Abstract

The blank for a variable volume packaging container has a side wall (3) with flanks (5) extending upwardly from the base (2) and connected by pairs of flaps (7) formed by articulated triangles. In the larger volume condition, the side wall (3) is raised upwardly and in the smaller volume position, the flanks (5) are joined.

Description

L'invention se rapporte à un contenant de volume variable.The invention relates to a container of variable volume.

Classiquement, un contenant comprend: - un fond, - une paroi latérale et éventuellement, un couvercle. Dans certaines applications, il peut être intéressant de pouvoir moduler le  Conventionally, a container comprises: - a bottom, - a side wall and possibly, a cover. In certain applications, it may be advantageous to be able to modulate the

volume de ce contenant.volume of this container.

On connaît, par exemple, des contenants constitués d'un fond et de plusieurs tubes montés coaxialement de manière à en faire varier la hauteur par  We know, for example, containers consisting of a bottom and several tubes mounted coaxially so as to vary the height by

coulissement des tubes.sliding of the tubes.

On connaît également un contenant constitué d'un fond rectangulaire à partir duquel fond s'élèvent quatre flancs de matière, chacun de largeur inférieure à la dimension du coté du fond auquel il se rattache et ces flancs sont reliés deux à deux par une paire de volets rectangulaires articulés de manière que ces volets, soit puissent s'étendre dans le prolongement des flancs, soit puissent être pliés  There is also known a container made up of a rectangular bottom from which bottom rise four flanks of material, each of width less than the dimension of the side of the bottom to which it is attached and these flanks are connected two by two by a pair of rectangular flaps hinged so that these flaps can either extend into the sidewalls or can be folded

vers l'intérieur du contenant pour former un coin rentrant.  inward of the container to form a nip.

Pour ce changement de taille, les volets ne sont solidaires que des flancs  For this change in size, the flaps are only joined to the sides

qu'à partir d'une certaine hauteur du fond.  only from a certain height from the bottom.

Un tel montage ne présente guère d'avantage.  Such an arrangement hardly presents any advantage.

Un des résultats que l'invention vise à obtenir est un contenant du type  One of the results that the invention aims to obtain is a container of the type

précité qui apporte notamment une nouvelle fonctionnalité.  mentioned above which notably brings a new functionality.

A cet effet, I'invention a pour objet un contenant comprenant: - un fond, - une paroi latérale, - éventuellement, un couvercle et - des moyens pour en modifier le volume, ce contenant étant caractérisé en ce que: - la paroi latérale est constituée par des flancs s'élevant depuis le fond reliés entre eux par des paires de volets de forme globalement triangulaire articulés, d'une part, entre eux et, d'autre part, sur les bords latéraux des flancs précités jusqu'au fond, avec la pointe de chaque triangle qui est solidaire du fond du contenant, de sorte qu'au moins sur une certaine hauteur à partir du fond, il n'y a pas discontinuité de paroi entre le fond, les flancs et les volets et que dans la position de plus grand volume, la paroi latérale s'évase vers le haut et dans la  To this end, the invention relates to a container comprising: - a bottom, - a side wall, - optionally, a cover and - means for modifying the volume thereof, this container being characterized in that: - the side wall consists of sides rising from the bottom connected together by pairs of flaps of generally triangular shape articulated, on the one hand, between them and, on the other hand, on the lateral edges of the aforementioned sides to the bottom , with the point of each triangle which is integral with the bottom of the container, so that at least over a certain height from the bottom, there is no wall discontinuity between the bottom, the sides and the flaps and that in the position of greatest volume, the side wall flares upwards and in the

position de plus petit volume, les bords des flancs sont jointifs.  position of smaller volume, the edges of the sides are contiguous.

L'invention sera bien comprise à l'aide de la description ci-après faite à titre  The invention will be better understood with the aid of the description below made by way of

d'exemple non limitatif en regard du dessin qui représente: - figure 1: vue de dessus d'un contenant, - figure 2: vue de dessus d'une variante du contenant, - figure 3: un détail du contenant de la figure 1 en position volume minimum,  non-limiting example with regard to the drawing which represents: - Figure 1: top view of a container, - Figure 2: top view of a variant of the container, - Figure 3: a detail of the container of Figure 1 in minimum volume position,

- figures 4 et 5: deux flancs de la paroi reliée par deux volets.  - Figures 4 and 5: two sides of the wall connected by two flaps.

En se reportant au dessin, on voit un contenant 1 comprenant -un fond 2, une paroi latérale 3, - éventuellement, un couvercle et  Referring to the drawing, we see a container 1 comprising -a bottom 2, a side wall 3, - optionally, a cover and

- des moyens 4 pour en modifier le volume.  - Means 4 for modifying the volume.

Selon une caractéristique de l'invention: - la paroi 3 latérale est constituée par des flancs 5 s'élevant depuis le fond 2 reliés entre eux par des paires 6 de volets 7 de forme globalement triangulaire articulés, d'une part, entre eux et, d'autre part, sur les bords latéraux des flancs 2 0 précités jusqu'au fond, avec la pointe de chaque triangle qui est solidaire du fond du contenant, de sorte qu'au moins sur une certaine hauteur à partir du fond, il n'y a pas discontinuité de paroi entre le fond, les flancs et les volets et que dans la position de plus grand volume, la paroi 3 latérale s'évase vers le haut et dans la  According to a characteristic of the invention: - the lateral wall 3 is constituted by flanks 5 rising from the bottom 2 connected together by pairs 6 of flaps 7 of generally triangular shape articulated, on the one hand, between them and , on the other hand, on the lateral edges of the aforesaid flanks 20 to the bottom, with the tip of each triangle which is integral with the bottom of the container, so that at least over a certain height from the bottom, there is no wall discontinuity between the bottom, the sides and the flaps and that in the position of greatest volume, the lateral wall 3 flares upwards and in the

position de plus petit volume, les bords des flancs 5 sont jointifs.  position of smaller volume, the edges of the sides 5 are contiguous.

Dans une forme de réalisation, les moyens d'articulation des volets induisent lors du passage du grand volume en petit volume un placement des volets à l'extérieur de l'enveloppe délimitée alors essentiellement par les flancs  In one embodiment, the means of articulation of the flaps induce during the passage from the large volume to small volume a placement of the flaps outside the envelope then essentially delimited by the sides

constituant la paroi latérale du contenant (figure 2).  constituting the side wall of the container (Figure 2).

Dans une autre variante de réalisation, au moins certains des flancs sont reliés par deux paires 6 de volets 7, de sorte qu'en position dite de petit volume, chaque paire 6 de volets se rabat contre la paroi interne des flancs de manière à  In another alternative embodiment, at least some of the flanks are connected by two pairs 6 of flaps 7, so that in the so-called small volume position, each pair 6 of flaps folds against the internal wall of the flanks so as to

occuper le moins d'espace possible.occupy as little space as possible.

Cela est très intéressant, car le contenant peut avoir une double fonction, une fonction d'emballage classique, par exemple, pour une bouteille de champagne et, du fait de l'étanchéité qu'assure au moins un certain temps la  This is very interesting, because the container can have a double function, a classic packaging function, for example, for a bottle of champagne and, because of the seal that ensures at least some time the

continuité de paroi, une fonction de seau à glace dans l'autre position.  wall continuity, an ice bucket function in the other position.

L'intérieur du contenant pourra être recouvert d'une feuille plastique. La hauteur des volets triangulaires sera inférieure à la hauteur des flancs, de sorte que ces volets disparaissent notamment dans la variante de réalisation  The interior of the container may be covered with a plastic sheet. The height of the triangular flaps will be less than the height of the flanks, so that these flaps disappear in particular in the alternative embodiment

(figurel ou 3) à double paire de volets entre les flancs.  (figurel or 3) with double pair of flaps between the sides.

Au lieu de quatres volets, on peut utiliser six volets.  Instead of four components, six components can be used.

Selon que l'articulation des volets sera réalisée par une ligne d'amincissement locale de la matière depuis la face externe ou depuis la face interne de la paroi latérale, le positionnement des volets se fera automatiquement  Depending on whether the flaps are articulated by a local thinning line of the material from the external face or from the internal face of the side wall, the positioning of the flaps will be done automatically

à l'extérieur ou à l'intérieur du contenant en position petit volume.  outside or inside the container in small volume position.

L'angle d'ouverture des volets en triangle dicte l'amplitude de l'évasement  The opening angle of the triangle flaps dictates the amplitude of the flare

du récipient.of the container.

Toutefois, pour que ces volets puissent se rabattre sur les flancs sans se chevaucher, la plus grande dimension transversale " d " des volets sera au plus  However, so that these flaps can be folded over the sides without overlapping, the largest transverse dimension "d" of the flaps will be at most

égale à la demi-largeur " D " du flanc sur lequel les volets se plaquent.  equal to the half-width "D" of the side on which the flaps are pressed.

Ainsi, plus cette plus grande dimension " d " transversale sera éloignée de  Thus, the further this greater transverse dimension "d" is from

2 0 la base du récipient, moins le récipient sera évasé et inversement.  2 0 the base of the container, the less the container will be flared and vice versa.

Cela apparaît clairement au regard des figures 4 et 5 o en figure 4, l'évasement est plus important que dans le cas de la figure 5 tout en ayant les  This is clearly seen from Figures 4 and 5 o in Figure 4, the flare is greater than in the case of Figure 5 while having the

mêmes dimensions " d ", " D ".same dimensions "d", "D".
