Description

Cylindrical cookie stack container round.

The present invention aims at a container formed, which associates a piece of paper or cardboard and a film superimposed, surrounding a stack of rigid products.

These packages are commonly used in the field of agri-food techniques for packaging Especially products such as cookies.

To make an opening of said conditioning, a tear band is generally used that allows you to trim the film on its perimeter and extract the end superior conditioning, thus giving access to products. Said container is disclosed in document US2926833.

This type of conditioning has a certain number of inconveniences

First, especially in the case of a cylindrical conditioning, and because the piece, Generally corrugated cardboard, closely surround the products, Cookie extraction is not especially easy. Also said conditioning is not compatible with effective rear closure, which forces you to quickly consume the contents of the package a open time

The present invention relates to a conditioning device that has a good level of tightness and allows easy access to products, and eventually an easy back closure.

To this end, the invention relates to a formed container surrounding a stack of rigid products, and associate a piece of paper or cardboard and a film overlapping, characterized in that the piece has a cutting area that defines an area of pretention of the products, and why the film presents a band that is supportive and that covers at least in part said cutting zone, the film and the band forming a device of opening that allows to free the zone of cut, being able to be carried out the extraction of successive products by gravity placing the container standing.

The presence of the planned cutting area in the piece allows to use any opening device, advantageously open and close, capable of freeing the cutting area and allow access to products.

Indeed, the piece of paper or cardboard allows ensure sufficient rigidity of the container in an upright position and form a kind of self-supporting distributor, even taking into account for the localized weakening provided by the area of cut.

The solidarity band of the film can present an adhesive layer that supports the band and the piece outside  from the cutting area. This especially allows closing back of the container

According to an embodiment that allows also a subsequent closure of the container, the piece has a section of adhesive band covered with a protective band, which is arranged for example near a cutting edge or an edge Of the piece.

The band can extend from a first edge to a second opposite edge of the movie.

According to an advantageous embodiment, the contour of the piece fits the contour of the film, and the piece and the film are superimposed so as to leave, so less at one end, a margin that allows the film to form by folding at least one package fund. The piece and the film may be superimposed so as to present an edge common.

It is advantageous for said band to overflow so less on one side of the piece.

The film can present a band in over-thickness along said solidarity band of the film, so as to limit the breakage of the film, in direction to one end of the film, especially an end that form a bottom of the package.

According to a preferred embodiment, the device is characterized because the film has a tongue cropped that is significantly in correspondence with the area cutting, and because the solidarity band of the film is constituted by a label that adheres to the film in a overflowing surface of the clipped tongue of the film way to form an opening-closing device.

The container can be cylindrical or parallelepipedic, and at least one bottom of the container may be formed at least in part by a fold of the film to the along one edge of said piece.

The film can present an overflowing area of the piece and that is overlapped with the film, with welding along the welding line.

It is especially advantageous to have an area of Start of breakage in the welding line.

Other features and advantages of the invention they will appear better by reading the following description, carried out as a non-limiting example, with reference to drawings, in which:

- Figures 1a and 1b illustrate the first variant of the invention, in which the part is provided with a cut, illustrating figure 2 a mode of use in the form of a cylindrical shaped container, which can be opened in accordance with Figures 3 and 4;

- Figures 5a and 5b illustrate the second variant of the invention, FIG. 6 illustrating a mode of use in the form of a cylindrical shaped container, represented in open position;

- Figures 7a and 7b illustrate another variant in which the piece is equipped with a precut in line discontinuous or other;

- Figures 8 and 9 illustrate a mode of use in the form of a cylindrical shaped container that can be opened from conformity with figures 3 and 4.

In accordance with Figures 1a and 1b representing the first variant of the invention, the piece 1 of paper or cardboard, more specifically of corrugated paper or cardboard, has an opening consisting of a cut 16 of width l and length l 0 allowing the output of the products, for example cookies. For a cylindrical package, the length l_ {0} is at least equal to half the perimeter of the package. For products extracted laterally, the width is greater than or equal to their height. The opening of the package is carried out by pulling the film 2 especially of plastic material, in particular polyolefin, of a thickness of for example a few tens of microns, thanks to a breakage start, for example some cuts 27, located for example at level of longitudinal weld 25 of
package.

Band 3 can be in solidarity only with the film 2, but preferably it can also be in solidarity with the piece 1 out of the cut 16. In addition, the part of the band 3 in longitudinal overflow of the film 1 beyond the edge 14 of the it can also be coated with an adhesive layer that It allows a subsequent closure of the package after use.

In the case represented in which band 3 only is in solidarity with movie 1, it is advantageous to provide piece 1, to proximity of its edge 14 (or an edge 18 of the cut 18), of a piece of adhesive strip 17 provided with adequate protection. After the first opening of the package, the protection is removed of the adhesive strip piece 17, so as to allow a closure easy container.

In the embodiment shown, the band 3 is a band of a face attached to the inner face of the film 2 and at the same level as cut 16 of piece 1. The function of band 3 is to allow film 2 to break out of the perimeter of the cut 16. Indeed, the films are generally of materials for which the propagation direction of a Breakage is not exactly predictable. With band 3, the break is sparingly separates from the edges of band 3, while not It can penetrate its perimeter.

The length l_ {0} of the cut is longer or equal to the half perimeter of the cookie, and its height l is greater than or same as a cookie, in the case of a container cylindrical.

To manufacture the container, the removal of the band adhesive 3 is made directly on the film 1. The cutting of the opening 16 in part 1 can be done well at the same time as the contour cut of part 1 according to its length, or shape separated. The removal of the piece of protected adhesive strip 17 is before or after cutting the contour of part 1 and / or the opening 16.

It should be stressed that a thin adhesive strip 4 can be placed below the strip 3 that serves to open in order to control the direction and orientation of the breakage in the case of a bioriented polymer film 2, so as to avoid the breakage does not go to the bottom of the package
tea.

The consumer picks up movie 2 and the band adhesive 3 at the level of the cuts 27 and rips perimetrically the film so as to release the cut 16 and allow access to products 40, for example cookies (see figures 3 and 4), which ensures a grip and lateral extraction of the same as the length released from the cut 16 reaches the middle perimeter of the cylindrical package. The grip area 16 as well released being located near a bottom of the package (for example at a distance equal to the thickness of one, two, even three products), cookies can be extracted by gravity by placing the foot package.

A distance equal to the thickness of at least one product between the grip area 16 and the bottom of the package allows ensure sufficient rigidity despite cutting 16.

In accordance with Figures 5a and 5b, the film 2 features a clipped tongue 30 for example rectangular. The tongue 30 is advantageously clipped in a perimeter not closed, for example on three trimmed sides 31, 32 and 33, allowing an articulation line 36 of the tongue 30 to remain in relation to the film 2 between the ends 34 and 35 of the sides 31 and 33.

To facilitate the passage through a machine, especially the displacement of piece 2 during the container shaping, trimmed sides 31, 32 and 33 are advantageously sympathetic in points 37 to piece 2. Said 37 points offer negligible resistance during the opening.

The solidarity band of movie 2 is consisting of a label 50 with an internal adhesive face superimposed on trimmed tongue 30, as depicted in the figure 5b. Label 50 has two edges 51 and 52 that are spaced from the edges 31 and 33 of the tongue 30, outside the perimeter of it. Also, a pretention area 53, advantageously non-adhesive on its inner face, it is separated from the edge 32 of the tongue 30, outside the perimeter thereof.

Advantageously, the tongue 53 is bordered by at least in part by lines of weakening 55 (for example dashed lines or lines of low resistance) that serve especially security seal of the container.

Advantageously, some weakening lines, for example precuts 57, line a joint line 54 of the label 50 located to the vertical of line 36 or slightly beyond it outside the perimeter of the tongue 30.

To open the container, the user takes the edge 53 of label 50 and displays it as shown in the Figure 6, dragging the tongue 30 whose outer face is integral by adhesion of the inner face of the label 50, which releases cut 16 of part 1 and allows access to products.

In the variant illustrated in Figures 7a and 7b an adhesive strip 3 is used to associate two materials, ie a piece 1 of paper or cardboard, more specifically of paper or cardboard corrugated, and a film 2 especially of plastic material, in particular polyolefin, whose thickness is in general some tens of microns Piece 1 and movie 2 are in solidarity with level of a precut 15 made in piece 1. A start of the breakage made in particular at the level of longitudinal welding of the package formed, allows, pulling the film, to lay the same tearing at the same time precut 15 of piece 1. The movement is carried out in all or part of the length l 2 of the piece 1, in order to allow access to products, by Example cookies. The subsequent closure can be done by application of the adhesive strip 3 in overflow of the piece 1 against the film 2 on which it is folded, for example at the level of the longitudinal welding 25 of the formed package.

The adhesive strip 3 has a width less than or equal to the distance between precuts 15 in part 1 and can be:

-

         a transferable tape (protection / adhesive / protection) or either a layer of adhesive deposited between piece 1 and the film 2,

-

         a double sided band (protection / adhesive-support-adhesive / protection), an adhesive face being in contact with the film 2 and the another face in contact with film 1,

-

         a single-sided band with a soldering support (adhesive-soldering support), meeting face adhesive in contact with part 1 and the non-adhesive face but welder welded to film 2, adhesion being performed between the support and film by welding, thermal or not, in part or the entire adhesive strip.

The precut 15 'of width l (for example two discontinuous precut lines 15 or two reduction lines thickness) is made in part or in full length l2 of the package part and, in any case, in a length Enough for the extraction of the products. The width l is also sized according to the products. For cookies extracted laterally, is greater than or equal to the height of the cookies.

In the case of a transferable tape or a band double-sided, the adhesive strip can be placed first in one of the two materials, with removal of protection before contacting the other material.

In the case of a single-sided band with soldering support, the placement of an adhesive tape is carried out first in piece 1.

In the case of a transferable tape or a band double-sided, the length of the adhesive strip 3 deposited is less than or equal to the length L2 of the film 2 used for the container

In the case of a single-sided band with soldering support, the length of the deposited adhesive strip 3 is less than or equal to the length l 2 of part 1.

In the embodiment of figures 7a and 7b, piece 1 has a width l 1 and a length l 2 and the precut 15 'of the width l extends between an edge of end 11 and the other end edge 14, parallel to the sides longitudinal 12 and 13, being separated by a distance m from edge 13. The assembly of part 1 and film 2 is done matching edges 11 and 21 respectively of piece 1 and film 2, leaving lower and upper margins M_ {1} and M_ {2} that allow a fold of the film 2 to form at less partly a package fund at each end.

The film 2 has a width L_ {1} and a length L2, said length L2 being preferably longer to the length l2 of the piece 1, so that the adhesive strip 3 and the film can overflow to allow adhesion of the film on itself, corresponding length l 2 of the piece 1 substantially to the perimeter of the package formed around the products. In figure 1b, it is also observed that the band 3 is arranged so as to partially or completely cover the area precut 15 of piece 1.

Finally, at one end of the band that overflow of part 1, a breakage is planned, by example cuts 27. In the example shown, said cuts 27 they start at edge 24 of movie 2.

Figure 8 illustrates the case of a container cylindrical, especially for round cookies in the case where the length of the adhesive strip 3 is equal to the length of the film 2. The cuts 27, which border on the edge 24 of the film 2, are provided at the level of longitudinal welding 25 of the package whose funds are made by folding the ends of the film 2 that exceed the edges 12 and 13 of the piece 2.

The consumer picks up movie 2 and the band adhesive 3 at the level of the cuts 27 and rips perimetrically the film and precuts 15, so as to release the products 40, for example cookies (see Figures 3 and 4), which allows ensure a grip and lateral extraction thereof in when the length of precut torn reaches half perimeter of the cylindrical package The 15 'grip area thus released remaining located near a bottom of the package, cookies can removed by gravity by placing the foot pack.

Figure 9 illustrates the case in which the length of the adhesive strip 3 is equal to the length l 2 of the piece 1. In this case, precuts 27 can always be done at the level of longitudinal welding 25, but since the beginning of the opening is done by pulling only on film 2 until the breakage joins edge 14 of piece 1 to tear next the set of film 2 and precut 15 'to release the products 40, as in the case of figure 2.

It is understood that, in the case of a container cylindrical, the length of the precut can be greater than or equal to half perimeter of the container, while in a container square or rectangular, the length of the precut can be longer or equal to the length of one side of the container, in order to ensure Product extraction
