Description

tote bag

technical field

The invention relates to a handbag with a bag body and an outer shell, the bag body has at least one handle, and the outer shell has an introduction port and an introduction device connected with the bag body.

Background technique

Handbags, here especially shopping bags, encompass a wide variety of variations with regard to the material and design of the bag body. Especially in the field of shopping bags, for example plastic bags made of polymers or paper strips are widespread. Such bags are typically displayed at the checkout counter in retail stores, such as supermarkets, so that customers who do not bring their own bags can safely transport their purchases home. Such plastic bags are mostly not intended for multiple use and are often disposed of immediately after transporting the goods to the home, which is especially harmful from an ecological point of view. Bags made of other materials, such as fabric bags, although designed for multiple uses, have the disadvantage that they take up relatively much space and are therefore durable in rare cases, e.g. Carry it in your bag. Therefore, it often happens that when you need it urgently, the fabric bag just happens to be out of hand. Furthermore, fabric bags also have the disadvantage that their capacity is really limited compared to the space they occupy. Finally, so-called mesh bags are often used as shopping bags. This type of mesh bag is composed of mesh or mesh-like materials, most of which also have a certain degree of elasticity, so this type of bag has a relatively large capacity while occupying a very small space. However, users do not like to carry mesh or mesh bags in other transport containers, such as handbags or travel bags, because the mesh fabric is prone to soiling during unprotected transportation and other objects in the handbag will be damaged. Hooking with the mesh or mesh fabric, so that the user can only grab the contents of the handbag or the mesh or mesh shopping bag by himself after very laboriously dismantling the objects hanging from each other.

Ultimately, all these inconveniences lead to the fact that the user often does not have his own bag to use if necessary and therefore has to resort to ecologically unfavorable plastic bags when shopping.

Contents of the invention

The technical problem underlying the present invention is therefore to provide a handbag, in particular a shopping bag, which avoids the above-mentioned disadvantages. In particular, the carrying bag according to the invention should be reusable, be stored easily and without problems in other containers, such as handbags or travel bags, and offer a large loading volume compared to the space requirements.

This technical problem is achieved by a handbag having the features of claim 1 . Advantageous developments of the invention are characterized by the subclaims.

The present invention therefore relates to a handbag, in particular a shopping bag, with a bag body and a casing, the bag body has at least one handle, the casing has an inlet opening and an inlet device connected to the bag body, wherein the bag body according to the invention It is characteristic that the insertion opening and the insertion device are designed in such a way that the bag is folded in the shape of a tube when inserted into the housing and is wound up in the housing.

Therefore, it is firstly the object of the present invention to provide a carrying bag with a special protective shell. In German patent document DE 19840410C2, disclose a kind of method and equipment for preserving reticulated or reticulated object. In this patent it is proposed to provide a housing around a net-like or mesh-shaped object with a return mechanism, wherein the return mechanism grabs the object and introduces the object into the housing in an introduction opening through a substantially point-shaped fastening area, which fastening area Compared to the size of the net-like or mesh-like body, which is small, the introduction opening is likewise small compared to the rolled-out net-like or mesh-like body. Meanwhile, DE 19840410C2 basically relates to a retaining net, for example for protecting loads in the trunk of a car. In addition, however, it is mentioned that the net-like or mesh-like objects can be hammocks, ladders, protective nets, filter nets, etc., and finally also bags. However DE 19840410C2 neither studies the specific structure of such bags nor the details of a suitable return mechanism for everyday use of such bags.

The present invention now proposes to develop the insertion opening and the insertion device of the bag known from DE 19840410 C2 in such a way that the bag body is folded in the shape of a tube when it is introduced into the housing and is wound in the housing. The hose-like folds of the bag ensure that the bags do not get tangled or knotted when being introduced into the housing and thus impede the pulling process. The winding of the hose thus formed ensures a space-saving storage of the bag in the housing. When the bag according to the invention is not in use, it is also pulled back substantially completely in the casing. At the same time, the casing surrounds the bag substantially completely and prevents the bag from being soiled and affected by other objects. Thus, the bag according to the invention can, for example, be stored without problems with other objects in a transport container, such as a handbag or travel bag, without the danger that other objects will catch on the bag or soil it. or in other ways.

In addition, tote bags provided with shells can be provided in a variety of shapes, and can be made into real fashion items from everyday items such as shopping bags. The housing is typically a plastic housing which can be designed in different shapes and colours. The housing is in particular a space-saving housing, for example, if it has a flat cylindrical shape with preferably rounded edges. At the same time, the axis of the cylinder is basically consistent with the scroll. In this case, the insertion opening is preferably arranged on the outer surface of the rounded cylinder in such a way that the insertion of the bag is substantially tangential to the axis of rotation.

Of course, the housing can also be made of other materials, such as sheet metal or wood. It is particularly preferred if the housing is formed in two parts, wherein, in the case of a flat cylindrical housing, the two half-shells are joined substantially at a center plane situated perpendicularly to the axis of rotation. After the insertion device of the carrier bag according to the invention has been installed, the two outer shell halves are connected to each other during production, for example by gluing, screwing, welding, riveting or, particularly preferably, by means of suitable fitting snap-in mechanisms . According to the first embodiment, the two housing half-shells are connected to each other so that they can no longer be separated by the user during normal use. According to a second embodiment, the housing half-shell can be disassembled by the user, for example unscrewed, so that in this embodiment the bag can be detached from the introduction device in order to clean the bag separately, for example.

The insertion device preferably comprises a roller mounted rotatably in the housing, on which the bag is fastened. When the bag is introduced into the housing, it winds up on the rollers in its folded configuration.

The roller preferably has return means for introducing the bag into the housing. The resetting device can be designed, for example, as a manually rotatable handle, so that the user can rewind the bag on the roller after the bag has been used. However, the restoring device particularly preferably comprises an elastic spring device which ensures automatic introduction of the bag after use. The spring device is tensioned when the bag is pulled out of the housing, so that it provides the restoring force required for reinserting the bag. At the same time, the spring device is preferably designed as a helical spring.

The introduction device preferably comprises a locking device, which can assume a first position, in which the introduction device is unlocked, and a second position, in which the introduction device is braked or locked. At the same time, the first position of the introduction device with unlocking corresponds to the position of introducing the bag into the housing, while the second position corresponds to the position of using the handbag. Such a locking device is particularly required when elastic restoring means are provided for automatically introducing the bag into the housing.

According to a first alternative, the locking device can be locked automatically. It is thus possible to use, for example, spring-loaded pins which, after the bag has been pulled out, engage in suitable detents which can be provided, for example, on the rollers. For unlocking the locking device, for example, an actuating element can be provided, such as a user-operable button, which moves the spring-loaded pin out of the catch mechanism again, so that the reset device can be released and the bag can be reinserted. The button can also have a detent which can cooperate with a cooperating detent provided in the introduction to lock the introduction in the direction of introduction, that is to say in the direction in line with the wrapping direction of the bag in the housing rotation. The button is preferably arranged so that it can move axially toward the interior of the housing against the restoring force of a spring element arranged in the traction element. At the same time, the button releases the catch, preferably in the position pressed into the housing, and initiates a rotation of the insertion device in the insertion direction.

According to a particularly preferred alternative, the locking device can be unlocked automatically, so that the user does not have to actuate an actuating element for releasing the locking device at all. The automatic unlocking of the locking device can be implemented, for example, in that the locking device can be released by pulling the bag past the locking position. Suitable designs for automatic unlocking and insertion of the bag are known from the field of cable winches for domestic appliances, for example for vacuum cleaners, in which the spring-loaded winding device is released by pulling the power supply cable and the cable is reconnected. Inhaled into the enclosure. For example DE A1574391 describes an electrical device with a cable roller comprising a spring winch for a power supply cable, wherein the spring winch is supported by a plurality of fixed pins supported on a circumference around the winch shaft and associated fixed pins For fastening, the fastening screw and the fastening pin act in the direction of rotation and their engagement into the detent mechanism is dependent on the rotational speed.

According to another alternative for the automatic release of the locking device, the central journal of the roller has a toothed structure on a certain part of its circumference, into which a rotatably mounted, spring-loaded rocker engages middle. The toothed structure and the shape of the rocker are designed such that, in the first position of the rocker, not only the rotation of the roller in the same direction as the introduction bag is locked but also the pivoting of the rocker into its second position . But the rollers can rotate in the same direction as the bag body is pulled out. On the other part of the circumference of the journal there is no toothing, so that the rocker can pivot into its second position, wherein the roller can rotate in the direction of insertion into the pocket.

According to another embodiment of the handbag according to the present invention, the locking device may comprise a slider, which is preferably tightly closed to the inner surface of the casing and engages with the rollers at the above two positions. In the first position, the slider releases the rollers so that the bag can be pulled out of the housing, while the movement of the slider in the second position locks the rollers and thus, for example, by pulling out the tensioned reset device of the bag It is also not possible to pull the bag back into the housing. As soon as the slider has been moved from the second position back into the first position, the roller is released and the reset device can cause the bag to wrap around. When the slide block is tightly closed with the inner surface of the housing, it is ensured that the hose-shaped folded bag can be wound.

The roller can have two guide discs at its two axial ends, which likewise preferably close the inner surface of the housing tightly. The guide disc may have a toothing into which the flange of the slider in the second position engages, thereby locking the rotation of the roller.

The bag preferably has at least one stop which abuts against the insertion opening when the bag is inserted into the housing. At the same time, the stop is designed such that it is larger than the inner diameter of the insertion opening at least in one direction. The stop thus prevents the bag from being completely introduced into the housing. The user is more able to grasp the bag at the stop and pull the bag out of the housing for use. The recessed opening on the housing and the stop are preferably shaped in such a way that the stop, when inserted into the bag, blends into the overall shape of the housing in an aesthetically appealing manner and forms, for example, a closed housing in this position. contour.

Particularly preferably, the stop is arranged on the handle of the bag. The stopper can be provided, for example, as a two-part plastic body, for example around the handle during the manufacture of the bag according to the invention, or around one handle if two handles are provided and for example by welding or Bonding interconnects.

The bag itself can consist of different materials, for example cloth fabric or plastic fabric. However, the bag body particularly preferably consists of a mesh and/or mesh material. Therefore, on the one hand, the lightness of the shopping bag is realized, and on the other hand, the large capacity of the shopping bag is realized. The mesh or mesh material preferably has anisotropic elasticity, so that the capacity of the bag can be adapted to various needs. At the same time, the anisotropic elasticity is preferably such that the substantially vertically oriented fibers or threads of the net-like or mesh-like material have only minimal elasticity when carrying items in the shopping bag and ensure a substantially constant length of the shopping bag, The horizontally extending threads or fibers are highly elastic so that the bag can be adapted to the required transport volume.

According to a particularly preferred embodiment, the bag comprises two interconnected cutouts with rounded corners. This configuration of the bag ensures that the bag can be introduced into the housing or pulled out of the housing without hindrance.

Thus, on the one hand, the bag can be made of light, weight-saving material, and on the other hand, it has high stability and cannot be broken when transporting heavy items, such as beverage bottles and the like, the bag body The handle is preferably formed by a strap which is folded at its end regions to the upper edge of the trim and is connected to the trim, while the central region of the strap is spaced from the upper edge of the trim so that there is a gap between the strap and the trim. A handle opening is formed between the upper edges. This ensures a uniform force transmission of the handle into the two cutout parts, thus reducing the risk of breaking when transporting heavy objects. Furthermore, a reinforcing strip can also be provided in the central region of the strap, which is connected, for example sewn, to the end region of the upper edge of the cutout.

According to another embodiment of the carrying bag according to the invention, the bag body is releasably connected to the introduction device. The bag can thus be washed or otherwise cleaned independently of the housing, for example. Furthermore, different bags, for example different in design and/or material, can also be used with the same housing. The bag can, for example, be fastened releasably to a strap or a cord which is fixedly connected to the introduction device. If the strap or string consists of elastic material, it preferably has at least such a length and elasticity that the fastening means for releasably fastening the bag can be pulled out of the housing and actuated by the user. Suitable fastening means are, for example, buttons, twist connections, riveting, zip connections and the like.

The outer surface of the shell of the bag according to the invention can be designed in various ways. Thus, for example, advertising printing can be provided or a small mirror can be integrated into the surface of the housing. However, the outer surface of the housing particularly preferably has fastening means for releasably fastening the disk-shaped object. The disc-shaped object is preferably a shopping trolley coin, such as is required in a supermarket in order to unchain a shopping trolley that is chained to a storage station.

Detailed ways

An embodiment of a carrier bag according to the invention, indicated generally at 10 , is shown in FIG. 1 . The handbag 10 has an outer shell 11 which, in the example shown, consists of two half-shells 12 , 13 which are connected to one another along a center surface 14 by snap-in means 15 , 16 . The snap-in mechanism includes a flange 15 protruding outward from the edge of the half shell 12 (refer to FIG. 2 ), which engages in a cooperating opening 16 which leaves a recess in the edge region of the half shell 13. mouth. The housing 11 has a substantially oval housing opening 17 through which a body 18 of a carrier bag, shown only schematically, can be pulled out. To this end, the bag 18 has a stop 19 in the region of its handle, which cannot be seen in FIG. The edges of the opening 17 abut and thus prevent the bag 18 from being completely introduced into the housing 11 . The stop 19 also serves as a handle by means of which the user can pull the bag 18 out of the housing 11 . As can be seen in FIG. 1 by the bag 18 shown only schematically in a partially drawn position, the insertion opening 17 and the housing 11 are shaped such that the bag 18 is folded together in a hose-like manner when inserted into the housing 11 . , thereby achieving a space-saving and orderly storage of the bag body 18 in the housing and thus enabling unhindered use of the carrier bag 10 according to the invention. Furthermore, the housing 11 has a slide 20 which is shown in FIG. 1 in its first position, in which the pouch 18 can be pulled out and inserted. If the slider 20 is moved forward in the guide rail 21 , that is to say in the direction of the insertion opening 17 , as will be explained in detail in particular in connection with FIG. 2 , it locks the withdrawal and insertion of the pocket 18 . In the example shown, the housing 11 has substantially the shape of a flat, rounded cylinder. On the front face 22 of the cylinder there is provided a fastening device designed as a clip 23 which releasably holds a shopping cart coin 24 . In the example shown there are provided three clips 23 distributed on a semicircle, which protrude outwards through the front end face 24 of the housing 11 in an inverted "L" shape. The distance defined between the horizontally extending leg 25 of the L-shaped profile and the front face 22 corresponds approximately to the thickness of the shopping cart coin 24 in order to secure the coin 24 with a press fit. When using the coin 24 for shopping, the user can easily push the coin parallel to the front face 22 in the direction of the semicircular area of the coin circumference where the holding card holder 23 is not provided, so that the coin is loosened by the holding card holder.

The function of the handbag according to the invention is shown in detail in FIG. 2 by means of a schematic diagram of the outer shell 11 , wherein the half shell 13 and the bag body 18 are omitted, so that the internal structure of the outer shell 11 can be better observed. The housing 11 has a roller 26 arranged rotatably in the housing, which is arranged rotatably about an axial journal 27 . One end of a only schematically shown coil spring 28 engages in the journal 27 , the other end of which is connected to the roller 26 . The bag body 18 shown in FIG. 1 is fixedly connected to the roller at its end opposite the stop 19 serving as a handle. When the bag body 18 is pulled out from the inlet 17 , the roller rotates against the reset force of the coil spring 28 , so that the coil spring is applied a prestress in the direction of pulling back the bag body 18 . When the bag 18 is released, the rollers 26 draw the bag 18 into the housing 11 again in the opposite direction. In order to fix the roller 26 in the pulled-out position under the tension of the coil spring 28, the slider 20 can move along the inclined inner surface 29 of the housing 11 so that the flange of the slider 20 protrudes into the inside of the housing 11 30 meshes with a toothed structure 31 provided on the roller 26 . In the example shown, the toothing 31 is arranged on the outer edge of a guide disc 32 arranged at the axial end of the roller 26 . A corresponding toothing can be provided on a similar guide disc 32 arranged at the opposite axial end of the roller 26 . In this case, the slide is also designed symmetrically and has a further, identical flange 30 which engages with the toothing of the second guide disk. The guide disc is preferably part of the integrated roller 26 . The guide discs are inserted into corresponding depressions in the inner surface of the housing so that they substantially seal the inner surface tightly. The slider is correspondingly designed such that the flange 30 is arranged at the end of an arcuate section 33 which likewise seals off the housing inner surface tightly. Thereby it is ensured that the locking device formed by the guide disc 32 of the slide block 20 and the roller 26 will not affect the unfolded bag body 18, that is to say it will not be hooked with the bag body in particular, thereby ensuring the introduction and pulling of the bag body. Unhindered functioning of the exit and locking mechanism. The bag itself may be non-detachable or releasably mounted on the rollers 26 for cleaning, repair or replacement purposes.

In the embodiment of the housing 11 shown in Figures 1 and 2 there is provided a mobile slider for locking the rollers 26, while Figures 3 and 4 show an embodiment of the invention with self-locking and self-locking rollers. tote bag. In the diagrams of FIGS. 3 and 4, the components indicated by the same reference numerals increased by 100 perform the same or corresponding functions as the components in the embodiment shown in FIGS. Describe its function in detail.

In FIG. 3 is shown an axial cross-section of the housing 111 in a self-locking and self-unlocking embodiment of the bag according to the invention. The roller 126 provided in the housing 111 here also has a coil spring (the coil spring is not shown therein because it is a sketch), which is applied when the bag body (also not shown) is pulled out from the introduction port 117. stress. In an alternative form for self-locking and self-unlocking of the locking device, the central journal 127 of the roller has a toothed structure 151 in an area 150 of its circumference, a rocker mounted rotatably about an axis 152 and loaded by a spring 153 The rod 154 can engage in this toothed structure. The shape of the toothed structure 151 and the rocking bar 154 is designed so that in the first position shown in FIG. And when the roller rotates to the direction that the bag body is introduced, the tooth surface of the toothed structure and the rocking bar 154 are mutually locked. In the region 155 of the circumference of the journal 127 no toothing is provided, so that in this region under the influence of the torque applied by the spring 153 the rocker 154 can pivot into its second position, in which the opening The rotation of roller 126 to the direction that bag body is introduced.

FIG. 5 shows a top view of the bag body 18 of the tote bag according to the invention. For the sake of brevity, the net or mesh structure of the bag body will not be described again. The bag body 18 comprises two cutout parts 34 , 35 arranged one above the other shown in FIG. 5 , which are sewn together along a U-shaped edge 36 . In the region of their substantially convex, curved upper edge 37 , the two cutouts 34 , 35 are not connected to one another and thus form the opening of the pocket 18 . Each convex arc 37 of the cutouts 34 , 35 has in its central region a concave cutout 38 defining a lower edge of a handle opening 39 . The upper edge of the handle opening 39 is formed by a strap 41 forming a handle 40 which extends to both sides of the handle 40 in the region of the upper edge 37 of the convex surface of the cutouts 34 , 35 . The strap 41 wraps the upper edge of each cutout part 34 , 35 in this area in an inverted U-shape and is connected to the cutout part 34 , 35 by a seam 42 . In FIG. 6 , which shows a corresponding cross-section along the line VI-VI of FIG. 5 , it can be seen that the welt formed in this way is designed in three layers at the upper edge 37 of the convex side of the cutouts 34 , 35 . An efficient transmission of the force exerted by the handle 40 over the entire upper part of the bag body 18 is thereby ensured, so that there is no risk of the bag tearing even when transporting heavy items. In order to ensure a three-layer stable structure in the region of the handle 40, a further belt layer 43 is inserted here in the U-shaped pleated belt 41 and connected with a seam 44, as shown in particular in FIG. 7 . As can be seen in the illustration, it shows a section along the line VII-VII of FIG. 5 . The free ends of the straps 41, 43 protruding outwards can be closed by seams. Also provided in the region of the handle 40 at least on one side of the structure defined by the two cutouts 34 , 35 is the above-mentioned stop 19 (shown only in dashed lines in FIG. 5 ). As can be seen in Figure 8, which shows a section along the line VIII-VIII of Figure 5, the upper edge 38 of the concave surface of the cutouts 34, 35 is folded twice so that it also forms a three-layer stable edge , this edge is fixed by seam 45. In the lower region of the bag is likewise sewn a triple-pleated strap 46 which is connected with its free end 47 or 48 to the rollers 26 , 126 of the housing 11 , 111 . As can be seen in FIG. 9 , which shows a section along line IV-IV of FIG. 5 , the triple-wrapped strap 46 is secured by two seams 48 , 49 .

The interior space of the bag body 18 is defined in such a way that the free ends of the trimmed parts 34, 35 point inward from the seam along the U-shaped edge 36, so that an externally clean joining edge 36 is produced. When using the bag, whether the shell 11 is carried in a hanging manner inside the bag in the bottom region of the strap or outside the bag depends on whether the shell 11 is connected to the end 48 of the strap 46 protruding into the defined inner space, or to the strap 46 is connected with an externally directed end 47 . Since the shell 11 must in any case be arranged outside the inside of the strap before being introduced into the bag 18 , it is necessary to turn the bag over before being introduced into the bag 18 in the case of the shell being fastened to the end 48 of the strap 46 .

According to an alternative form of the invention, the bag can be detachably connected to the introduction device of the housing by means of suitable fastening means (not shown here).

In FIG. 10 is shown an axial cross-section of a housing 221 of another embodiment of a handbag according to the invention. This embodiment of the housing is self-locking and unlockable by the user with button 270 . In this embodiment the roller 226, which is rotatably arranged in the housing 221, also has a helical spring (not shown there because it is sketched) which acts to push the bag (also not shown) out of the inlet. Tensioned when pulled out, in the representation in FIG. 10 the insertion opening is located in a cut-away housing part and is therefore not visible in this figure. A helical spring is disposed between the central journal 227 and the roller 226 . The ends of the helical spring (not shown) are respectively fixedly connected to the journal 227 or the roller 226 so that the helical spring is compressed when the roller 226 rotates relative to the journal 227 . When the handbag is pulled out from the housing 221, the roller 226 rotates opposite the journal 227 and simultaneously tensions the coil spring, because the handbag 18 is fixedly connected to the outer surface of the roller 226 with its end 47 or 48 (referring to FIG. 5 ). Joining, for example by gluing or spot welding.

The embodiment of the housing 221 shown in FIG. 10 also comprises again two half-shells 212 and 213 which are mechanically connected to each other along the mid-plane 214 by suitable fastening means 215 , 216 . Additionally or alternatively, the two half-shells can also be bonded to each other along the center plane 214 .

A recess 256 is provided in the upper half shell 212 , in which the shopping cart coin 224 is arranged such that the surface of the shopping cart coin 224 substantially closes the upper half shell 212 tightly. The shopping cart coin 224 is releasably arranged in the recess 256, wherein the inner diameter of the recess and the outer diameter of the shopping cart coin are dimensioned such that the shopping cart coin 224 is held firmly in the recess 256 on the one hand and on the other hand. On the one hand, it can be easily removed by the user from the recess 256 . For this purpose it can be provided, for example, that the recess 256 has a peripheral groove 257 into which the outer edge of the shopping cart coin 224 engages after the coin has been pressed into the recess 256 . Since the surface of the housing part 212 is raised in the exemplary embodiment shown, the planar shopping cart coin 224 rests non-planarly with its outer edge on the recess 256 . The user can thus tilt the edge of the cart coin 224 relative to the bottom of the recess 256 by lightly pressing it so that the elasticity of the coin 224 and/or the elasticity of the material of the housing half 212 defined by the recess 256 is sufficient to lift the coin out of the recess. 256 out of slot 257 and thus loosen from housing 221.

The locking and unlocking mechanism of the housing 221 in FIG. 10 will be described in detail below with reference to the scroll wheel 226 shown in detail in FIG. 11 and the button 270 shown in detail in FIG. 12 .

As can be seen in FIG. 11 , the rotatable roller 226 comprises a hollow roller 258 in which an axially extending slot 259 is left for tensioning a coil spring (not shown). In order to better illustrate the inner structure of the roller 226, the hollow roller 258 is shown partly broken in FIG. 11 . At the end of the hollow roller 258 directed toward the button 270 there are radially inwardly directed locking wedges 260 which each have an inclined slide surface 261 and an essentially axially extending stop surface 262 .

Furthermore, spring tongues 263 are provided which run diagonally through the interior of the hollow drum 258 and which are slightly offset relative to the wedge 260 axially in the direction of the center of the hollow drum 258 .

Button 270 is shown in detail in FIG. 12 . The button 270 is inserted into the recess 264 of the lower case 213 of the case 221 (refer to FIG. 10 ). The outer edge 271 of the button 270 is designed so that it engages the edge of the recess 264 with a peripheral shoulder 272 extending on the edge of the recess 264 in the interior of the half shell 213, so that the button 270 does not move in the inserted state. Will fall out from the half shell 213. The button 270 is arranged axially displaceably in the housing half-shell 213 , wherein a peripheral shoulder 272 forms a stop for the outward movement of the button, while the button engages the roller 226 during axial movement inwardly of the half-shell 213 . The elastic reed 263 leans against each other. On the side of the pushbutton 270 directed toward the interior of the housing 221 there is provided a guide roller 273 into which the recess of the journal 227 can engage (cf. FIG. 10 ). A radially extending locking wedge 275 is provided on the outer circumference of the guide roller 273 , which can cooperate with the locking wedge 260 of the roller 226 for locking and unlocking of the roller 226 . The locking wedges 275 also each include an inclined sliding surface 276 and an essentially axially positioned stop surface 277 . The locking wedges 276 and 260 are arranged so that they are in the direction of rotation of the roller 226, which is the direction in which the tote is pulled out, which is consistent with the tension of the coil spring, enabling the roller 226 to overcome the tension of the coil spring. Rotation is performed by the return force of the spring. Once the tension on the tote is released, the return springs of the rollers 226 attempt to rotate in the opposite direction. However, due to the very small angle of rotation determined by the number of locking wedges, the stop surface 262 of the locking wedge 260 of the roller 226 abuts against the stop surface 277 of the locking wedge 276 of the button 270, thereby preventing the roller 226 Keep spinning. Thereby the carrier bag according to the invention can be used. If the user wants to introduce the bag into the housing 211 again, he only has to press the outer surface 278 of the button 270 in order to push the button axially into the housing 211 by a short distance. Simultaneously, the locking wedges 275 or 260 , which are temporarily still relatively located in the stop, are moved axially towards each other and the locking mechanism of the roller is unlocked. The roller 226 can thus be swiveled into its rest position under the influence of the restoring force of the helical spring and at the same time the bag can be introduced into the housing 221 . The axial movement of the button towards the inside of the housing 221 , released by the operation of the button 270 , produces a deformation of the elastic tongue 263 of the roller 226 against which the edge of the guide roller 273 abuts. At the same time the elastic reed generates a restoring force against the pressure exerted by the user on the button 270 . Once the user releases the button 270 again, the restoring force generated by the elastic reed 263 causes the button 270 to move outward again, so that the locking wedges 275 and 260 can re-engage each other and lock the rotational movement of the roller 226 in the rolling direction.

In FIG. 13 a perspective view of an axial cross-section of a housing 311 of another embodiment of a handbag according to the invention is shown. The locking and unlocking mechanism of the housing 311 of FIG. 13 will be described in detail with particular reference to FIGS. 14 to 16 . Here, FIG. 13 shows an axial cross-section of a housing 311 of another embodiment. A perspective bottom view of the housing upper 312 with the button 370 inserted in the shell of the housing is shown in FIG. 14 , while FIG. 15 shows the scroll wheel 326 in detail. Finally, FIG. 16 shows the lower casing 313 of the housing. Components in the alternatives of FIGS. 13 to 16 are identical or have similar functions to those of the alternatives of FIGS. 1 and 2 and the alternatives of FIGS. Figure labels are indicated and will not be described in detail.

This embodiment of the housing is also self-locking and can be unlocked by the user via button 370 . A roller 326 rotatably provided in the housing 311 has a coil spring (not shown there because it is sketchy) which acts to pull the tote bag (also not shown) from the inlet 317 shown in the drawing. Pulled tight on exit. In the illustration of FIG. 13 the insertion opening 317 is closed by a handle 319 serving as a stop. The helical spring is arranged between the central journal 327 and the roller 326 and works like the helical spring already described in relation to FIG. 10 .

The housing 311 comprises two half-shells 312 and 313 integrally formed along a mid-plane 314 . In the exemplary embodiment shown, the two housing half-shells 312 , 313 are pressed together during installation, so that the respective circumferential return hooks 315 , 316 arranged at the edge of the shell engage with each other.

The central journal 327 serving as the axis of rotation has a slot 379 which can widen in a V-shape at the upper end. A fastening hook 380 with a wedge-shaped contour is arranged on the tip of the journal 327 . Due to the gap, the journal 327 is pressed together during installation, so that its tip can engage via a fastening hook into an opening 374 provided on the underside of the button 370 . Once the tip of the journal 327 passes through the opening 374, the retaining hook grabs the edge of the opening. Overall, this embodiment (in combination, if necessary, with gluing or welding of the edges of the housing) prevents undesired opening of the housing 311 by the end user.

The coins are inserted on pins provided for this purpose on the underside of the housing; the downward inclination of the surrounding coins enables the coins to be removed by tilting.

In the alternative form of FIG. 13 , the recess 356 is again provided in the lower half-shell 313 for the shopping cart coin 324 , so that the surface of the shopping cart coin 324 substantially seals the surface of the upper half-shell 313 tightly. The bottom surface of the recess 356 and the surface of the coin 324 do not fit precisely, so the cart coin 324 is retained in the recess 356 but can be released by the user by tilting it.

As can be seen in FIG. 15 , the rotatable roller 326 comprises a hollow roller 358 in which an axially extending slot 359 is left for tensioning a coil spring (not shown). In the assembled state of the housings, the rollers 336 are surrounded by guide rings 381 , 382 which are formed in the inner surfaces of the upper housing half 312 and the lower housing half 313 . To pull out the shopping net (not shown), the roller 326 is rotated by tension on the handle 319 connected to the net and a spring engaged at one end in the journal 327 and fixed at the other end in the slot 359 of the roller is tensioned . The cylindrical roller 326 has in its interior two elastic locking wedges 360 which each have an inclined sliding surface 361 and an essentially axially extending stop surface 362 . On the side of the button 370 directed toward the interior of the housing 311 there is provided a guide roller 373, on its outer circumference a radially extending locking wedge 375 is provided, as already shown in FIGS. 10 to 12 in an alternative form, Locking wedge 360 is cooperable with roller 326 for locking and unlocking roller 326 . The locking wedges 360 may be mated with corresponding locking wedges 375 on the outer circumference of the guide roller 373 based on their elasticity clockwise. The button is pressed outwards in its rest position aligned with the housing surface. Once the tension on the shopping net is released, the return spring turns the roller 326 counterclockwise so that the fronts of the locking wedges 360 and 375 are separated from each other and the return movement of the roller for introducing the web is stopped. By pressing the button 370, the locking wedge 375 of the upper housing is pressed down and slides under the locking wedge of the roller. The stopping of the return movement of the shopping web is thus canceled and the shopping web is completely re-engaged by the pressure of the spring.

The opening 374, into which the journal 327 of the shaft engages, prevents wedging of the shaft by pressing the button. The elasticity of the locking wedge 360 enables the button to spring back. In order to facilitate the reset movement of the button, if necessary, an elastic reset device, such as a spring leaf or an elastic pad, can be provided on the tip of the journal and the bottom surface of the button.

Although the invention has been described with reference to an exemplary embodiment in which the bag is connected in the region of its base to the insertion device and has a handle in the region of the handle, all possible alternatives are also conceivable. For example, the bag can also be connected in the region of its handle to the insertion device of the housing. In this case, the handle is advantageously arranged in the region of the bottom of the bag.
