The adoption is envisaged of reliefs on the lower wall of the flange (10) of the small frame, and of branched fins (30) arranged in the peripheral groove (12) of said small frame, into which the edge of the external container is inserted, in order to increase the surface area for adhesion, promote the distribution of the glue and to create barriers to the passage of air for the purpose of improving the hermetic sealing of the lid during the use of the packaging. The upper edge of the external container can also have a differently shaped configuration in order to improve adhesion.

Description

Packaging system containing a small bag and an outer case

Field of the invention

The present invention relates to an integral lid to a pouch, and the pouch is inserted such that the single lid frame is a system of fastening a small frame to an outer shell into which as a whole forms a box-like package which is hermetically sealed during use.

BACKGROUND OF THE INVENTION

Packages of this type are already known and consist of a square shaped inner bag containing, for example, vacuum-packed roasted ground coffee, an outer case usually made of hard cardboard and a small frame with a solid lid made of plastic material that is attached to both the inner bag and the outer housing.

Such packages generally have insufficient connection both between the lower surface of the small frame bead and the inner bag, as well as between the upper edge of the outside

The essence of the invention of the shorter sleeve and the small frame itself, the spiritual seal that the negative product, especially in the case of coffee, the wall of the bag visible in the opening of the breakthrough sufficient hermetic upper flange of the small frame that is

The object of the present invention is to provide a small frame with an integral cap made of plastic material with a fastening system having the following advantages in relation to other versions already on the market:

a) better adhesion of the small frame rim with a solid lid to the surface represented in this case by the vacuum

(b) better air-tightening of the fastening: the zone between the em and the sachet is greater when the small frame is attached to the outer casing, represented, for example, by hard cardboard.

The excellent adhesive properties achieved using the fastening system of the present invention provide the packaging with greater hermetic and improved resistance to pressure conditions that

They often arise during transportation and use of household conditions,

Therefore, a fastening system 11 has been specifically developed for packaging roasted and ground coffee, although this system is also applicable to various types of products such as peanut biscuits, cocoa and the like.

cleaning

Overall, the invention provides a better way of attaching an element made of a plastics material, such as a discharge element, to a housing.

According to the invention, the fastening system is based on a combination of one or more of the following characteristics:

(a) the groove portion of the small frame frame of the manufactured plastic material into which the edges of the outer housing are introduced has branched fastening ribs. This branched multidirectional contact with the adhesive on the planes to be connected by means of multiple alignment in space.

As a result of the increase in the surface area of the appropriate alignment of the frame, which is provided with an adhesive, and the ribbing, the adhesion force when connecting the outer casing to the small frame is greater.

b) the lower surface of the frame of the small frame made of plastic material is shaped, not smooth.

This design of the fastening flange provides inconsistency to this surface, and therefore the adhesive layer that attaches the small frame to the bag is applied.

three dimensionally. This increases the surface area of the small frame to be bonded, splits the tearing presses into the elongation and shear displacement components and thus improves the adhesion between the small frame and the fastening means. In addition, the introduction of downstream lines along the entire perimeter of the molded part provides a better air seal of the joint by the effect of the gas exchange baffles present from one side to the opposite side of the adhesive layer.

(c) moreover, it is envisaged that the upper edge of the outer casing, which is intended to be attached to the skirt, has a non-uniform surface finish instead of a flat smooth finish. This non-uniform treatment of the top edge of the sleeve also allows for a three-dimensional and multidirectional contact of the glued areas, thereby increasing the surface area of the sleeve to be adhered and the force being distributed over the elongation and shear displacement components.

's

Box packs are already known, and these packs include the use of a lid made of a plastic material affixed to both the inner pouch and the outer housing.

the possibilities of tensioning the package are overall

Limited by the effect of a smooth uniform surface intended to bond the parts.

In addition, the fastening strips used in the prior art packages for fastening a small frame with an integral cap to the outer casing. provide a limited surface area for gluing, while the branched referencing structure of the invention provides a more beam-oriented orientation of the bonded surfaces with the ability to increase adhesion in all necessary directions.

Similarly, a uniform and smooth bonding of the small frame flange is known, which is used to connect the small frame with a solid cap made of plastic material to the support surface. The contoured non-uniform configuration of the fastening flange of the present invention provides a three-dimensional and multi-directional orientation of the bonded surface, followed by the adherence of adhesive forces in all directions. The adjacent fastening lines provide a better air seal.

if impermeability properties are required in the bonded zones.

In addition, the finish of the fastening skirt limits leakage of adhesive when two components are joined, and such a finish also allows suitable adhesive application in addition to the intended purpose in the desired direction, thereby improving adhesion to other parts of the surface.

Finally, the non-uniform treatment of the upper fastened edges of the outer shell, similarly to the present invention, provides a much better adhesion compared to the flat and uniform configuration of the bonded surface that exists in all prior art carton packaging packages.

internal filled

This package, denoted as a whole by a bag of ground and ground hard cardboard coffee, consists of a small symbol X containing, with a parallel arrangement of sides, a product 3 for example a vacuum-packed outer casing 4 formed for example;

6, which is connected to a closing cap 8 which opens on a hinge made of the same material as said small frame.

The small frame 7 takes the form (see the frame provided with the skirt 10 when the leakproof bag 2 is fastening, including but not limited to sticking to the edge of the outer casing 4.

Regarding those adjustments 10 and 1 2. of the present invention, the first of which is extremely critical and important, since it must create an optimal air seal in order to avoid a decrease in the senses of the product qualities contained in the product after its opening during use, when reliability depends on good sealing of the closure cap. provided with a seal

20, which at the edge 22 of the small frame Z-slot 12 to hold the joint at the edge of the outer sleeve 4 is also critical in that it allows the entire rigid package to be sealed, which is resistant to mechanical stresses and transport pressures; use.

In order to improve the joint edge 14 of the sleeve 4 inserted into the groove 12, there are in accordance with the invention a number of branched ribs 30 (see also FIGS. 3 and 3 for example) on two mutually opposite sides, each comprising a plate 32 connected to the rib. 34, which is part of the wall of the respective small frame.

The rib 36 appears to be a limited protrusion S on the plane of the plate 32, creating a nonuniformity that contributes to a better adhesion of the edge 14 of the outer shell wall inserted into the groove 12.

The backrest 35 of the ribs 34 is considered in the direction of the plane of the skirt 10 to create conditions for guiding the edge 14 of the wall of the outer casing 4 during preparation of the wrapping, which is usually automated.

The plates 32 of the branched ribs 30 may be of any other shape and size as in FIG. Third

It will be understood that at least one branched rib 30a of the previously described type is also applied in the front center zone of the small frame (see Figures 2, 5 and 6) for the same reasons.

A further improvement of the present invention aimed at better joining the upper wall of the inner pouch 2 to the lower surface of the skirt 10 is to provide said zone with a shaped surface treatment in the preferred embodiment of FIG.

Thus, for example, the surface of the skirt is provided with a plurality of fine sampling cells 40 interconnected so as to form a plurality of bridging lines positioned between the small channels during surface treatment.

In FIG. 8 and shows an enlarged detail of the preferred cross-sectional solution. This surface treatment, whose elements 40 can produce a wide variety of geometric shapes, allows the formation of a large number of corners and recesses which multiply the possibility of joining the respective flange-pocket interface surfaces so that, during the joining operation, more uniformly small flow channels can be applied. i kmi

At the same time, the multiple elements 40, which are formed together, prevent the ingress of external air after bonding, thereby ensuring a hermetically sealed package during use.

The shaping of the surface finish reliefs of the skirt 10 and the guidance of the bridging lines to prevent air passage can be perfectly accomplished in different ways.

A possible alternative to the solution shown in FIG. 7, which remains within the scope of the mouse and the invention, can thus be seen in a schematic embodiment, for example in FIG. 10th

In accordance with the invention, it will be appreciated that the rim 14 of the outer casing 4 also has a non-uniform treatment on part or all of the surface, as shown, for example, in FIG. 11 and 12. This type of treatment, which molds or grooves on the carton reinforcements or utilizes a series of cavities or reliefs or any other methods known to those skilled in the art, increases
