Abstract

Package or container which once emptied of its contents can, under the effect of a pressure, undergo a modification of its overall size by folding the material and nesting the elements in each other and finally exhibiting a reduced volume with respect to its initial state.

Description

La présente invention concerne un emballage ou contenant, qui une fois vidé de son contenu, peut, sous l'effet d'une pression, subir une modification de son encombrement, par pliage de la matière et emboîtement des éléments entr'eux, et présenter à la fin, un volume réduit par rapport à son état initial. The present invention relates to a packaging or container, which once emptied of its content, can, under the effect of pressure, undergo a modification of its size, by folding the material and interlocking of the elements between them, and present at the end, a reduced volume compared to its initial state.

Habituellement, les contenants, après utilisation du produit qu'ils renferment, sont encombrants par leur volume. Ils prennent beaucoup de place et leur encombrement est un inconvénient dans les phases de leur récupération. Usually, the containers, after using the product they contain, are bulky by their volume. They take up a lot of space and their bulk is a drawback during the recovery phases.

L'emballage suivant l'invention permet de remédier à cet inconvénient. Il est constitué de tronçons cylindriques ou tronconiques, de diamètres différents, étagés, reliés entr'eux par des anneaux circulaires plus ou moins parallèles à la base, faisant épaulement, qui sous l'effet de la pression exercée, fléchissent en premier, -pour, l'un après l'autre, amorcer le pliage du cône ou tronc de cône qui leur est adjacent, et les emboîter entr'eux ; ces anneaux délimitent aussi la zone de pliage et d'emboîtement. The packaging according to the invention overcomes this drawback. It consists of cylindrical or frustoconical sections, of different diameters, stepped, connected between them by circular rings more or less parallel to the base, forming a shoulder, which under the effect of the pressure exerted, bend first, -for , one after the other, initiate the folding of the cone or truncated cone which is adjacent to them, and nest them together; these rings also delimit the folding and nesting zone.

Les dessins annexés illustrent l'invention
La figure l représente l'emballage avant réduction.The accompanying drawings illustrate the invention
Figure l shows the packaging before reduction.

La figure 2 représente l'emballage après réduction. Figure 2 shows the packaging after reduction.

En référence à la figure l, suivons le pliage d'un étage. Referring to Figure 1, let's follow the folding of a floor.

L'emballage est un appui sur la face 1. The packaging is supported on side 1.

Exerçons une force en F. Let's exert a force in F.

L'anneau 2 fléchit et amorce le pliage du tronc de cône 3. The ring 2 flexes and begins the folding of the truncated cone 3.

Le pliage continue sous la poussée du cylindre 4 jusqu'à ce que celui-ci vienne en butée sur l'appui, 1, ce qui va déclencher le fléchissement de l'anneau 5 et ainsi jusqu'au pliage de tous les étages. The folding continues under the thrust of the cylinder 4 until the latter comes into abutment on the support, 1, which will trigger the bending of the ring 5 and thus until the folding of all the stages.

L'invention concerne toutes les variantes de contenants dont le profil et la section permettent la réduction du volume par pliage et emboîtement de la matière. The invention relates to all variants of containers whose profile and section allow the reduction of volume by folding and nesting of the material.

Claims

1) - Packaging or container characterized in that it comprises a frustoconical profile, stepped, (3) (4), circular rings making shoulder (2) C5) and a section, allowing, under the action of a pressure , to bend the material and to fit the elements between them to finally obtain reduced overall dimensions compared to the initial packaging.

2) - Packaging or container according to claim 1 characterized in that it comprises a stepped profile (3) (4), of different diameters, such that they allow interlocking between them, in the folding phase.

3) - Packaging or container according to claims 1 and 2 characterized in that it comprises circular rings, forming a shoulder (2) (5), adjacent to each cylinder or truncated cone constituting the packaging, to create a zone of deflection, initiate folding, and accommodate nesting.
