Description

Packaging in a semi-rigid material with shock absorption system

The present invention relates to a packaging made of a semi-rigid material, such as cardboard or corrugated board, comprising at least one shock absorption system, particularly in the corners. This may lead to a package having improved strength, especially in terms of tearing, particularly in case of impact, for example following a fall.

Most known packages of semi-rigid materials may discharge all or part of their contents under the effect of shocks more or less violent. For example they can open, and in particular tear, under the effect of a shock. In some uses insufficient strength can be particularly problematic, especially in the case where packaging includes objects that should not spread. One can cite the case of very dirty objects, for example likely to smudge the environment, or especially of objects polluting and / or likely to be dangerous, in particular from a mechanical, chemical and / or biological point of view.

Indeed, in many cases, dangerous and / or polluting objects are packaged in cardboard packaging for subsequent processing or destruction. During transport, for example between the place of packaging or collection of these objects and the place of treatment or destruction, the packaging can suffer shocks, especially be thrown on each other. It is very important that during these shocks, the packages do not open and / or tear, in order to avoid a dispersion of the packaged objects. Solutions of the prior art for improving the strength of the packaging pass through an increase in the thickness of all or part of the material forming the packaging. This solution is expensive, may require a more complex assembly, is creative weight and / or environmentally expensive.

The present invention therefore aims to solve all or part of the problems mentioned above. In particular, the packages can absorb shocks, especially on the angles when falling. The energy of these shocks can be absorbed in whole or in part by a shock absorbing portion of the packaging. This energy is little or no impact on the rest of the packaging and / or objects contained. This can thus preserve the integrity of the objects and / or prevent any unintentional spreading.

According to a first aspect, the subject of the invention is a package comprising walls, a lower part, an upper part, and a shock absorbing system present in at least one corner zone, this system comprises present-molding lines. in at least one corner zone, in particular these upsetting lines have an angle ranging from 30 to 60 °, or even from 40 to 50 °, or even more particularly about 45 °, with respect to a fold line and / or an edge. The shock absorbing system (s) is (are) in particular present in the corners of the package.

Shocks caused by shocks, especially in the event of a fall, are very often located in the corner areas. The present invention may make it possible to reduce or even eliminate tearing, especially in corner areas, during shocks in these areas, particularly in the event of a fall.

Without wishing to be bound by this hypothesis, it is possible that the upsetting lines absorb a greater part of the impact energy than conventional packaging, in particular by an easier and controlled deformation, which can reduce the forces exerted on the surrounding parts which are likely to cause the rupture of the most fragile zones, in particular the fold lines near or adjacent.

The packaging or packaging according to the invention therefore comprises crease lines, these can in particular be straight or curved. These upsetting lines can be considered as preferential pre-folding lines, in particular these lines can be obtained by using on the cutting shapes of the pressers with intermittent perforation, mid-cutters, half-flesh or perforanting. In particular the upsetting lines extend either between two fold lines, between two edges, or between an edge and a fold line. These ends may be located on a fold line and / or an edge, at least 5 mm, or even at least 1 cm from an edge and / or a fold line, in particular fold lines wall, bottom or lid.

In particular, these upsetting lines have an angle ranging from 30 to 60 °, or even from 40 to 50 °, or even more particularly about 45 °, with respect to two fold lines, two edges or a fold line and a edge. The upstanding lines, in particular straight or curved, present on a plane of a corner zone can be parallel to each other. They may in particular be spaced apart by a distance ranging from 0.5 to 5 cm, in particular from 1 cm to 3 cm. These upsetting lines may be of identical length or on the contrary be shorter and shorter as one approaches the corner. In particular the ends of the crease lines are at an equal distance from the edge or the fold line.

According to one embodiment, these upsetting lines do not come into contact with a fold line and / or an edge.

According to another embodiment all these fold lines or a part thereof come into contact with a fold line and / or an edge. The upsetting lines are in particular present on at least part of the walls located in a corner zone, and in particular on all these parts. They may be present on at least part of the lower and / or upper parts perpendicular to the walls, and in particular on all the corner zones of the lower and / or upper parts.

They may still be present on at least a portion of the lower and / or upper parts parallel to the walls.

Shock abutment lines may be present on the upper corners and / or the lower corners, especially on all corners. In particular, the upsetting lines are present, or even only present, on parts that have a point of contact with the corner. The upsetting lines may in particular be present on a wall and / or on a bottom and / or cover element, in particular having a point of contact with the corner.

A corner can be understood in its common sense, and in particular as an inside corner of the package, especially once it closed. A corner may also be defined as the intersection point of three planes, for example selected from the wall planes, the top closure plane or cover, and the bottom closure plane or bottom. A wedge zone may be defined as a part of the package comprised in a circle having the corner for center and a radius, or a distance, greater or less depending on the product contained and / or the size of the package . For example, this radius may be 50 cm, in particular 30 cm, in particular 20 cm or even 10 cm. In another way, this radius correspond to 20%, especially 15%, especially 10% or even 5% of the height, width and / or depth of the package.

Alternatively, the package may include upsetting lines for shock absorption outside the defined area. According to another variant, the package does not include upsetting lines for the absorption of shocks outside the defined area.

In particular, the packaging according to the invention is single-grooved, that is to say it comprises, at least 50%, especially at least 80%, in particular at least 90%, or even at least 95%. % of its surface, a single layer of semi-rigid material and / or it is not doubled. However, it is conceivable that the package according to the invention is wholly or partly double or triple groove. In these cases, crushing of the crease lines may be deeper.

The package can be obtained from a single element, or flank, or from several elements glued together.

The upper part can in particular define a lid, it can close the top of the package. The lower part can in particular define a bottom, it can close the bottom of the package.

The package may comprise gripping means, in particular located above the closing portion of the top of the package. The package may include at least one, or even a single, glue tab for joining the body body, or include an inner lug and an outer lug. In this case each close blank may comprise a glue tab. The paw which is found inside is glued inside, the paw which is found outside is stuck on the outside. The outer leg may be more or less perforated to facilitate the volume of the body. Especially the package includes an automatic bottom.

In particular, the package may comprise within it, in particular in its closed part, a plastic bag, which may itself be closed. This plastic bag can be linked to the packaging, in particular to prevent unwanted movements of this plastic bag and / or objects they contain.

According to another of its aspects, the invention relates to a blank comprising: panels intended to form walls separated by fold lines, at least one panel intended to close the top of the package, articulated by a folding line on a panel intended to form walls, - at least one panel intended to close the underside of the package, articulated by a fold line on a panel intended to form walls, said fold line being perpendicular to the fold lines panels intended to form walls - discharge lines located in at least one area near an intersection of two fold lines, two edges or an edge and a fold line, in particular perpendicular.

By zone close to an intersection of two fold lines, two edges or an edge and a fold line, is meant in the sense of the present invention a circular zone having its center at the intersection of two lines of folding, two edges or an edge and a fold line and a radius as defined above.

Of course, the blank can provide a package according to the invention.
