Description

Twist open rigid packaging for tobacco products

technical field

The present invention relates to twist-to-open rigid packs of tobacco products.

The invention may be advantageously used in a cigarette pack, to which the following description refers by way of example only.

Background technique

Patent application WO2009010851A2 describes a swivel open rigid cigarette case comprising two partially separable containers, one of which is inserted into the other. More specifically, the inner container houses the group of cigarette packs and the inner container itself is housed inside the outer container such that the inner container is in a closed position relative to the outer container (in which position the inner container is inserted the interior of the outer container) and an open position (in which the inner container is partially removed from the outer container). The inner container has a hinged lid that is mechanically connected to the outer container by a connecting member so that the hinged lid opens "automatically" (i.e., without the need for the user to touch the hinged lid) as the inner container is moved relative to the outer container. closure. The main hinge about which the inner container rotates relative to the outer container is located at the front edge of the bottom walls of the two containers.

The swivel open rigid cigarette case described in patent application WO2009010851A2 is only in the closed position (i.e. when the inner container is inserted statically stable (ie, only remains 'upright') in the interior of the outer container). In other words, the cigarette pack is stable and remains 'upright' when 'upright' in the closed position, however, when 'upright' in the open position (i.e. the inner container is partially removed from the outer container) , the cigarette pack was unstable and fell forward. In countries where retailers of packs of cigarettes (or even loose cigarettes) are usually used to clearly displaying 'samples' of merchandise, the fact that the packs of cigarettes above do not stand 'upright' in the open position is an obvious one. shortcoming. Therefore, in the case of the cigarette pack described, the most effective display 'setting' (ie, in terms of advertising and/or promotion) is in the 'upright' open position (however, this is not possible).

Design patent DE20107274U1 describes a rigid cigarette case that rotates open and includes two partially separable containers, one of which is inserted into the other. More specifically, the inner container houses the group of cigarette packs and itself is housed inside the outer container such that the inner container is in a closed position relative to the outer container (in which position the inner container is inserted the interior of the outer container) and an open position (in which the inner container is partially removed from the outer container). A primary hinge about which the inner container rotates relative to the outer container is located midway along the respective bottom walls of the inner container and the outer container. In this cigarette case, however, the mechanical connection between the inner container and the outer container is relatively fragile and unstable, and can eventually result in a partial or complete separation of the inner container and the outer container near the main hinge.

Contents of the invention

It is an object of the present invention to provide a twist-to-open rigid pack of tobacco products designed to eliminate the above-mentioned disadvantages and which, in particular, is inexpensive and easy to produce.

According to the present invention there is provided a twist-open rigid pack of tobacco products as described above.

Detailed ways

The number 1 in Figures 1, 2 and 3 generally indicates a rigid cigarette pack that is swiveled open.

The cigarette pack 1 comprises a cigarette pack 2 (shown in Figure 3) comprising a group of cigarettes and a sheet of foil wrapping material wrapped around and completely enclosing the group of cigarettes. The sheet of wrapper material typically has a perforated tear line defining a removable top portion that is torn to open the pack and remove the individual cigarettes.

The cigarette pack 1 comprises a parallelepiped-shaped rigid inner container 3 containing the cigarette pack group 2 , and a parallelepiped-shaped rigid outer container 4 containing the inner container 3 . The inner container 3 is hinged to the outer container 4 along the main hinge 5 so as to be in a closed position ( FIG. 1 ) (in which the inner container 3 is inserted inside the outer container 4 ) and an open position ( FIG. 1 ) relative to the outer container 4 . 3) (in this open position, the inner container 3 is partially withdrawn from the outer container 4 ), thereby allowing access to the group of cigarette packs 2 .

The inner container 3 in the form of a parallelepiped is cup-shaped and has: an open top 6 for access to the group of cigarette packs 2; a bottom wall 7 opposite the open top 6; a front wall 8; a rear wall 9 , which is opposite and parallel to the front wall 8 ; and two opposite parallel side walls 10 . The inner container 3 comprises a hinged lid 11 which is hinged to the inner container 3 along a lid hinge 12 for an open position ( FIG. 3 ) with the open top 6 open and a closed position with the open top closed relative to the inner container 3 . Rotate between positions. The hinged lid 11 comprises: a rectangular top wall 13, which is opposite and parallel to the bottom wall 7 of the inner container 3 when the hinged lid 11 is closed; a rectangular rear wall 14, which forms a rectangular rear wall when the hinged lid 11 is closed. a continuation of the rear wall 9 of the inner container 3; and two triangular side walls 15 forming a continuation of the side walls 10 of the inner container 3 when the hinged lid 11 is closed. A lid hinge 12 connects the top edge of the rear wall 9 of the inner container 3 to the bottom edge of the rear wall 14 of the hinged lid 11 .

The outer container 4 is also parallelepiped-shaped and has a top wall 16 facing and parallel to the top wall 13 of the hinged lid 11 when the inner container 3 is in the closed position; 3 When in the closed position, the bottom wall is parallel to and opposite to the top wall 16, and the bottom wall faces and is parallel to the bottom wall 7 of the inner container 3; an open front end 18 through which the inner container 3 rotates; a rear wall 19 , when the inner container 3 is in the closed position, the rear wall is opposite to the open front end 18, and the rear wall faces and is parallel to the rear wall 9 of the inner container 3; and two opposite parallel side walls 20, when the inner container 3 is in the closed position In the closed position, the two opposite parallel side walls face and are parallel to the corresponding side wall 10 of the inner container 3 .

The hinged lid 11 has an automatic control system that connects the hinged lid 11 to the outer container 4 such that an opening/closing movement of the inner container 3 relative to the outer container 4 automatically produces a corresponding opening/closing movement of the hinged lid 11 (i.e. , the user does not need to touch the hinged cover 11). The automatic control system of the hinged lid 11 comprises: a control piece 21 ( FIG. 9 ), which extends from the edge of the top wall 16 of the outer container 4 towards the inside of the outer container 4 ; and a slot 22 ( FIG. 8 ), which inserts A slot is formed through the top wall 13 of the hinged cover 11 and the slot is engaged by the control tab 21 .

The cigarette pack 1 comprises stop members for limiting the retraction of the inner container 3 from the outer container 4 and thus defining a fully open position of the inner container 3 relative to the outer container 4 . The stop member comprises: two retaining pieces 23 ( FIG. 8 ), which protrude from the side wall 10 of the inner container 3 toward the outside of the inner container 3 and are located near the rear wall 9 of the inner container 3 ; and two Retaining pockets 24 ( FIG. 9 ) protrude from the side wall 20 of the outer container 4 towards the interior of the outer container 4 and are located near the open end 18 of the outer container 4 . In actual use, when the inner container 3 rotates around the main hinge 5 relative to the outer container 4 from the closed position to the open position, each retaining piece 23 slides in its respective retaining pocket 24 to prevent the inner container 3 from closing. take back.

In a preferred embodiment shown in the figures, the rear wall 19 of the outer container 4 has a through hole 25 shaped and dimensioned to allow the insertion of a user's finger. To open the cigarette pack 1 , the user grips the outer container 4 with one hand and inserts a finger inside the through hole 25 to exert a pushing force on the rear wall 9 of the inner container 3 and move the inner container 3 relative to the outer container 4 .

As shown in FIG. 3 , the main hinge 5 allows the inner container 3 to rotate relative to the outer container 4 and connects the bottom wall 7 of the inner container 3 to the bottom wall 17 of the outer container 4 . The main hinge 5 is located midway along the bottom wall 7 of the inner container 3 (i.e. approximately halfway along the bottom wall 7 at a first distance from the front edge of the bottom wall 7 and at a distance from the rear edge of the bottom wall 7 ). at the second distance), and the main hinge is located at an intermediate position along the bottom wall 17 of the outer container 4 (that is, approximately halfway along the bottom wall 17 at a first distance from the front edge of the bottom wall 17 and at a distance from the front edge of the bottom wall 17 The rear edge of the bottom wall 17 is at a second distance).

As shown in FIGS. 4 and 5 , the main hinge 5 about which the inner container 3 rotates relative to the outer container 4 passes through corresponding transverse fold lines parallel to the front and rear edges of the bottom wall 17 (at Clearly shown in FIG. 9 ) is directly formed on the bottom wall 17 of the outer container 4 . The front edge 38 of the bottom wall 17 of the outer container 4 is connected along a transverse fold line 37 to the trapezoidal web 26 (the main base of which is along the front edge 38 of the bottom wall 17), which is on one side (Partially) bonded to the inner surface of the bottom wall 17 of the outer container 4, and the trapezoidal connecting piece is (completely) bonded to the outer surface of the bottom wall 7 of the inner container 3 on the opposite side, so that the outer container 4 Connect to inner container 3. In other words, the web 26 is first folded 180° and bonded (partially) to the bottom wall 17 of the outer container 4 and then (completely) bonded (on the side opposite to the side glued to the bottom wall 17 of the outer container 4) to the bottom wall 7 of the inner container 3 .

As mentioned above, the main hinge 5 is located midway along the bottom wall 17 of the outer container 4, and the main hinge divides the bottom wall 17 of the outer container 4 into a front part 17" and a rear part 17', the front part and the rear part 17'. The bottom wall 7 of the inner container 3 is integral (the front part is glued to the bottom wall of the inner container) (i.e., rotates integrally with the inner container 3 ) and is thus detached from the remainder of the outer container 4; The remainder of the container 4 is integral and thus detached from the inner container 3. The web 26 is connected only to the front portion 17" of the bottom wall 17 by means of an adhesive 27 (shown in FIG. Attached (bonded) to the rear portion 17 ′ of the bottom wall 17 . The web 26 is fully bonded to the outer surface of the bottom wall 7 of the inner container 3 by means of an adhesive 28 (shown in FIG. 7 ). In other words, the web 26 is only partially bonded to the bottom wall 17 of the outer container 4 by the adhesive 27 (that is, only to the front portion 17 ″ of the bottom wall 17 ), but the web is bonded to the bottom wall 17 by the adhesive 28. Instead, it is completely glued to the bottom wall 7 of the inner container 3 .

In a preferred embodiment shown in FIGS. 4 and 5 , each side wall 20 of the outer container 4 has a flap 29 which is folded 90° relative to the side wall 20 (i.e. vertically) and Fully bonded to the bottom wall 17 of the outer container 4 (that is, to both the front portion 17″ and the rear portion 17′ of the bottom wall 17) by the adhesive 30 (shown in FIG. 6 ). Each The flaps 29 are each centrally traversed by a fold line 5b aligned with and superimposed on the fold line defining the main hinge 5 to allow the flaps 29 to be identical to the bottom wall 17 of the outer container 4 Rotate in a manner. Fold line 5b divides each flap piece 29 into a front portion 29 "and a rear portion 29', the front portion is superimposed on and bonded to the front portion 17" of the bottom wall 17, and the rear portion is superimposed on to and bonded to the rear portion 17' of the bottom wall 17. The rear portion 29' of each flap 29 is permanently connected to the side wall 20 along the fold line, while the front portion 29" of each flap 29 are temporarily connected to the side wall 20 along a tear line 31 which is torn when the cigarette pack 1 is opened, (i.e., when the pack of cigarettes 1 is opened, the tear line 31 is completely torn, thus, The front portion 29" of the corresponding flap 29 is permanently separated from the side wall 20). In a different embodiment, instead of the tear line 31, a split line is used which makes each flap 29 The front portion 29" is separated from the side wall 20.

A different embodiment not shown (and not the object of the invention) does not have the web 26, so that the bottom wall 7 of the inner container 3 is glued directly to the front part 17" of the bottom wall 17 of the outer container 4. This embodiment The way preferably has a flap 29 to prevent a gap from forming between the bottom edge of the side wall 20 of the outer container 4 and the side edge of the bottom wall 17 .

As shown in Figure 8, the inner container 3 is formed by folding a flat and generally elongated rectangular blank 32, parts of which are denoted as corresponding parts of the inner container 3 using the same reference numerals with superscripts where possible.

The blank 32 has two longitudinal fold lines 33 and a plurality of transverse fold lines 34 defining between the longitudinal fold lines 33: a panel 13' which forms the top wall 13 of the hinged lid 11; a panel 14' , which forms the rear wall 14 of the hinged lid 11; plate 9', which forms the rear wall 9 of the inner container 3; plate 7', which forms the bottom wall 7 of the inner container 3; and plate 8', which forms the inner container 3 front wall8.

Plate 14 ′ has two flanks 15 ′ forming side walls 15 of hinged lid 11 . The panel 9' has two side flaps 10', which respectively form the outer parts of the side walls 10 of the inner container 3, which are located on opposite sides of the panel 9' and connected to the panel 9' by a longitudinal fold line 33. separate. The panel 8' has two side flaps 10", which respectively form the inner part of the side walls 10 of the inner container 3, which are located on opposite sides of the panel 8' and connected to the panel 8' by a longitudinal fold line 33. separate.

As shown in Figure 9, the outer container 4 is formed by folding a flat rectangular blank 35 with appendages, parts of which are denoted as corresponding parts of the outer container 4 using the same reference numerals with superscripts where possible.

The blank 35 has four longitudinal fold lines 36 and a plurality of transverse fold lines 37 which define between the four longitudinal fold lines 36: a panel 16' which forms the top wall 16 of the outer container 4; 19', which forms the rear wall 19 of the outer container 4; the rear portion 17' and the front portion 17" of the bottom wall 17 of the outer container 4; and the connecting piece 26.

The panel 19 ′ has two side flaps 20 ′ forming the side walls 20 of the outer container 4 , which are located on opposite sides of the panel 19 ′ and are separated from the panel 19 ′ by a longitudinal fold line 36 . Each side flap 20' has a flap 29, a portion of which is attached to the side flap 20' along a corresponding tear line 31 and the remainder of which is attached along a corresponding transverse tear line 37. 20' to the flanks.

When placed 'upright' on a flat support surface (i.e., resting on its bottom wall), the cigarette pack 1 described has the advantage that in the closed position (i.e., the inner container 3 is inserted inside the outer container 4 ) and in the open position (ie inner container 3 partially removed from outer container 4), the cigarette pack is statically stable (ie remains 'upright'). This means that the pack of cigarettes 1 can be positioned 'upright' in both the closed position and the open position.

Furthermore, compared to the cigarette pack in patent application WO2009010851A2, the cigarette pack 1 described is also cheap and easy to produce since only minor changes need to be made which do not make the blank expensive/difficult to produce or to fold.

Finally, the web 26 provides a more stable mechanical connection between the inner container 3 and the outer container 4 by fully bonding the web on one side to the bottom wall 7 of the inner container 3 with an adhesive 28. The entire outer surface (thus forming a very strong mechanical connection), by bonding the web on the other side to the front portion 17" of the bottom wall 17 of the outer container 4 with an adhesive 27 and also by using a transverse fold line 37 is achieved by mechanically connecting the web to the bottom wall 17 (thus also forming a very strong mechanical connection).The web 26 also improves the bottom wall of the outer container 4 by hiding any exposed packaging material along the front edge 38 17 for the appearance of the front edge 38 .

Considering its numerous advantages, the design of the cigarette pack 1 described can also be fully applied in the manufacture of other types of rigid containers for tobacco products, such as cigarette cartons (in this case, a set of cigarette packs is used instead of a cigarette pack Group 2) or cigar boxes (in which case the preferred but not necessary cigar pack group is used instead of cigarette pack group 2).
