Abstract

In the bottom of the thermoplastic container, a projecting ridge (1) is formed, serving as support base for the upper container in the stack. The invention makes it possible to obtain stackable containers whose external lateral surface has no apparent relief. <IMAGE>

Description

La présente invention a pour objet un récipient, notamment en matière thermoplastique, pouvant être, à vide, empilé avec des récipients analogues afin de réduire l'encombrement lors du stockage et du transport.The present invention relates to a container, in particular of thermoplastic material, which can be, when empty, stacked with similar containers in order to reduce the space requirement during storage and transport.

On connaît de tels récipients composés d'un corps creux à axe longitudinal et formés d'une paroi de fond et d'une paroi latérale dont la section supérieure est plus grande que la section inférieure. Les récipients de ce type les plus courants sont en général tronconiques ou en tronc de pyramide.There are known such containers composed of a hollow body with a longitudinal axis and formed of a bottom wall and a side wall whose upper section is larger than the lower section. The most common containers of this type are generally frustoconical or in the form of a pyramid trunk.

Lorsqu'on empile de tels récipients les uns dans les autres, la surface inférieure du fond d'un récipient repose sur la surface supérieure du fond du récipient immédiatement inférieur dans la pile. Si un effort est transmis à la pile, la paroi latérale de l'un ou de plusieurs récipients risque de se déformer ce qui produit des coincements empêchant un prélèvement aisé indivuel des différents récipients composant la pile. Celà est incompatible avec le fonctionnement de machines automatiques de remplissage.When stacking such containers one inside the other, the bottom surface of the bottom of a container rests on the top surface of the bottom of the container immediately below in the stack. If a force is transmitted to the stack, the side wall of one or more receptacles risks deforming which produces jamming preventing easy individual removal of the various receptacles making up the stack. This is incompatible with the operation of automatic filling machines.

Afin de remédier à cet inconvénient, il a déjà été proposé de former dans chaque récipient, et plus précisément à la partie supérieure de celui-ci un bourrelet ou épaulement périphérique. Dans ce cas, lors de l'empilage, le bourrelet ou épaulement d'un récipient vient reposer sur la collerette ou partie supérieure du récipient immédiatement inférieur dans la pile. Ainsi, toute contrainte radiale sur les parois latérales est supprimée de sorte que celles-ci ne se déforment pas et qu'il n'y a pas de risque de coincement. Toutefois, une telle disposition s oppose pratiquement à l'application d'une décoration sur toute la surface latérale extérieure de la paroi.In order to remedy this drawback, it has already been proposed to form in each container, and more precisely at the upper part thereof, a peripheral bead or shoulder. In this case, during stacking, the bead or shoulder of a container comes to rest on the collar or upper part of the container immediately below in the stack. Thus, any radial stress on the side walls is removed so that they do not deform and that there is no risk of jamming. However, such an arrangement practically opposes the application of a decoration over the entire outer lateral surface of the wall.

La présente invention a pour objet de pallier cet inconvénient et de permettre la réalisation d'un récipient empilable dont la surface latérale ne présente aucun relief apparent.The object of the present invention is to overcome this drawback and to allow the production of a stackable container whose lateral surface has no apparent relief.

Selon la présente invention, le récipient notamment en matière plastique, composé d'un corps creux à axe longitudinal constitué par un fond et une paroi latérale dont la section supérieure est plus grande que la section inférieure est caractérisé en ce que le fond du récipient présente une arête surélevée faisant saillie par rapport à la surface supérieure du fond.According to the present invention, the container in particular of plastic material, composed of a hollow body with a longitudinal axis constituted by a bottom and a side wall whose upper section is larger than the lower section is characterized in that the bottom of the container has a raised edge protruding from the upper surface of the bottom.

Selon une autre caractéristique d'une invention, la face supérieure de l'arête est plate et d'une épaisseur supérieure à l'épaisseur du reste du récipient.According to another characteristic of an invention, the upper face of the edge is flat and of a thickness greater than the thickness of the rest of the container.

D'autres caractéristiques et avantages de l'invention apparaitront au cours de la description qui va suivre d'un mode particulier de réalisation donné uniquement à titre d'exemple non limitatif en regard de la figure unique qui représente schématiquement un empilage de deux récipients respectivement M et N.Other characteristics and advantages of the invention will appear during the following description of a particular embodiment given solely by way of nonlimiting example with regard to the single figure which schematically represents a stack of two containers respectively M and N.

Sur la figure, on voit que les récipients inférieur M et supérieur N réprésentés en coupe verticale selon leur axe longitudinal sont constitués essentiellement par une paroi latérale 2 fermée à sa partie inférieure par un fond 3. Dans l'exemple représenté, les récipients M et N sont terminés à leur partie supérieure par une collerette 6. A partir du fond 3 de chaque récipient fait saillie une arête ou une couronne circulaire 1. Cette arête présente elle-même une paroi latérale 4 terminée à sa partie supérieure par une face plane 5. Conformément à une caractéristique de l'invention, la face 5 est d'une épaisseur supérieure à l'épaisseur du reste du récipient.In the figure, it can be seen that the lower M and upper N containers represented in vertical section along their longitudinal axis are essentially constituted by a side wall 2 closed at its lower part by a bottom 3. In the example shown, the containers M and N are terminated at their upper part by a flange 6. From the bottom 3 of each container protrudes an edge or a circular crown 1. This edge itself has a side wall 4 terminated at its upper part by a flat face 5 According to a characteristic of the invention, the face 5 is of a thickness greater than the thickness of the rest of the container.

Dans le cas où le récipient est thermoformé cette suréépaisseur est obtenue automatiquement par le procédé de formage. Le thermoformage est effectué par un piston double qui commence dans un premier temps à former la partie centrale du fond 3 à l'aide d'un premier piston, puis dans un second temps le reste du récipient. Ainsi, la partie 5 n'est pas étirée contrairement à ce qui se produit sur l'ensemble du récipient. L'anneau ou arête 1 qui peut être circulaire ou de forme quelconque constitue une base résistante pour l'appui du récipient supérieur. La hauteur de l'anneau 1 dont la forme est indépendante de la forme du récipient définit le pas d'empilage.In the case where the container is thermoformed, this additional thickness is obtained automatically by the forming process. The thermoforming is carried out by a double piston which begins firstly to form the central part of the bottom 3 using a first piston, then secondly the rest of the container. Thus, the part 5 is not stretched contrary to what occurs on the entire container. The ring or edge 1 which may be circular or of any shape constitutes a resistant base for the support of the upper container. The height of the ring 1, the shape of which is independent of the shape of the container, defines the stacking pitch.

Ainsi, aucune force radiale n'est exercée sur les parois latérales 2 des récipients et ceux-ci restent parfaitement libres les uns par rapport aux autres. La surépaisseur de la face 5 permet de présenter une résistance élevée à l'écartèlement.Thus, no radial force is exerted on the side walls 2 of the containers and the latter remain perfectly free with respect to each other. The extra thickness of the face 5 makes it possible to have a high resistance to spreading.

Dans le cas où le récipient est fabriqué par injection, on prévoit bien entendu une épaisseur déterminée, supérieure à l'épaisseur moyenne du pot, entre le poinçon et la matrice.In the case where the container is produced by injection, there is of course a specific thickness, greater than the average thickness of the pot, between the punch and the die.

Bien entendu, l'épaisseur entre les parois 4 de l'anneau est très faible de sorte que la perte de volume intérieur du récipient soit pratiquement nulle, ce qui n'était pas le cas avec les fonds surélevés connus antérieurement.Of course, the thickness between the walls 4 of the ring is very small so that the loss of interior volume of the container is practically zero, which was not the case with the raised bottoms known previously.

La présente invention s'applique bien entendu à tous les cas de récipients empilables quelle que soit la nature de leur matériaux constituants et en particulier au cas des récipients pouvant contenir des liquides.The present invention applies of course to all cases of stackable containers whatever the nature of their constituent materials and in particular to the case of containers which may contain liquids.
