DETAILED DESCRIPTION OF THE INVENTION

TECHNICAL FIELD The present invention relates to a first cut member forming two cut members or trays made of cardboard or cardboard sheet material and an upper portion or case lid forming and engaging with said tray. A two-part packaging case of the type including a second cutting member.

[0002] The invention likewise relates to a cut-member assembly for obtaining such a packaging case, as well as to a method and a machine for manufacturing a case from the cut-member assembly.

The invention likewise relates to a method for unpacking such a case.

SUMMARY OF THE INVENTION The present invention is a rigid product that allows the product to be easily displayed on the outside of its shipping packaging in a clean and eye-catching manner, especially on a display shelf of a large store counter. In the field of packaging materials for packaging (wide-mouthed bottles, cans ...) or semi-rigid products (bags ...), they have particular but not exclusive use.

BACKGROUND OF THE INVENTION [0005] Packaging cases of the type described above which allow the upper part of the case to be quickly separated in relation to the lower part are already known (EPO 637,548).

[0006] However, such cases have the disadvantage that they do not allow easy, rapid and complete removal of all products from the packaging material, so that they can be displayed aligned on one shelf. .

DISCLOSURE OF THE INVENTION [0007] The present invention makes it possible, in particular, to completely remove a tray and a lid of packaging material by a few simple actions without touching the product, thus completely removing the packaging material from the product. In that it is possible to display all the products in the packaging on the store shelves perfectly, instantly and at once.
It is an object of the present invention to provide a case and a cutting member assembly which can better meet practical requirements compared to the prior art.

[0008] The case furthermore exhibits a high robustness and a fast tempo (20 cases / min).
Can be assembled automatically. The cases thus obtained according to the invention can be easily stacked on a pallet.

DETAILED DESCRIPTION OF THE INVENTION For this purpose, the invention relates to a two-part packaging case, in particular of the type described above, which is arranged to be seized by a user and the rest of the case. Having a first lateral side wall connected to the rest of the case by a partially pre-cut bondline that allows a user to peel it off in relation to the part; One or more other side walls, one or more partially pre-cut portions, which can be disengaged by manually applying a force perpendicular to the walls and pulling them apart, and / or A packaging case is provided, characterized in that it is fixed to one or more other side walls of the lid only by one or more bonding points.

[0010] A partially pre-cut portion (or sometimes more simply referred to below as a pre-cut portion) refers to the rest of the cutting member only at a few points of cooperation or portions. A fragile portion that is not attached and can therefore be easily unintegrated from the cut member by pulling perpendicular to the plane of the cut member.

The one or more partially pre-cut parts and / or the one or more bonding points are such that they exhibit an excellent resistance in the vertical direction, ie essentially in the plane of the wall, as long as they are stressed. Are located in

This resistance is completely sufficient, in particular, to allow the transport of the product even if the packaging material is trapped by the lid.

If, on the other hand, the separating stresses applied between the walls are distinctly perpendicular to the walls, these walls may advantageously be provided with this arm and / or pushback, for example for passage. After passing through a hard point where the user needs to apply a few Newtons of supplementary stress, such as with his thumb as a means, using a force of, for example, about 5-10 Newtons,
Easy release by hand without peeling of cardboard.

In addition, the tray and the lid now retain their rigidity unless the first side wall of the case is manually peeled off by the user, so that separation or opening between the tray and the lid is not possible. It should also be pointed out that this is further advantageously hindered by the above-mentioned hard point or points.

[0015] The engagement between the tray and the lid can be internal or external. That is, the tray wall may be positioned outside or inside the lid.

[0016] Advantageously, the first lateral sidewalls are two first sidewalls of the lid and the tray, respectively.
5,6; 70, 79).

Here, the tray and the first side wall of the lid, which are secured to each other by conventional solid bonding, for example by means of a glue strip of the “hot melt” type, are thus also likewise if there is no peeling of the cardboard With no possibility of separation, it also ensures excellent rigidity of the case.

[0018] Adhesion by an adhesive point, such as a partially pre-cut portion that is easily peeled off from the rest of the cutting member to which it originally belongs, conversely excludes the possibility of delamination. .

The first lateral side wall of the case has a catching means or is integrated with it, for example, so as to be captured by hand.

According to an embodiment of the invention described more particularly here, these capture means and partially pre-cut joining lines of the first lateral side wall are, in particular, the legs of the product Is provided in order to allow the user to peel off the first side wall of the case, in particular by releasing it completely.

Advantageously, it coincides with the edge of the case between the wall, the base and the lid.

Also advantageously, only partially pre-cut joining lines of the first lateral side wall of the case with the bottom surface coincide with the corresponding ridge and / or with the side wall adjacent to the first side wall. Only the partially pre-cut joint line coincides with the corresponding ridge.

For example, a user who can capture the side wall to be stripped with his entire hand is, for example, 1
It exerts a stripping force, such as ４4 kilograms, greater than the separating force for de-integrating partially pre-cut parts.

Advantageously, the legs of the product can always be removed from the side of the peelable surface, once by vertical or horizontal pull or twice by horizontal pull on each side. Can be stripped of the entire side surface or nearly the entire side surface (ie, at least 70% of the surface).

Advantageously, the partially pre-cut joint line (also sometimes more simply referred to hereafter as the pre-cut joint line) is, at the time of departure or at a later time, firstly of the cardboard. The first hard point resulting from the longer length of the cut part, and then possibly the supplementary one or two intermediate hard points, for example in the more easily peelable part It is cut to exhibit a more brittle part with a longer pre-cut part ending.

Thus, by dividing the peeling stress, it is better to ensure that the first side wall is not unintegrated in the event of unexpected stresses and / or side impacts on the case. It becomes possible.

[0027] Such measures can likewise be performed by stripping the first wall of packaging material and, for example, by means of a precut line with one or more hard points on the rest of the cutting member that supports it. Similarly, after the division of the partially pre-cut portions or glue points that are connected, the user removes the tray without the product while maintaining the lid in place on the product, and then It is also possible to remove the lid from the product, for example by lightly lifting and / or sliding horizontally along the product.
