Description

COWERCLE POUR RÉCIPIENT EN MATIERE PLASTIQUE
La présente invention a pour objet un couvercle en matière plastique notamment pour un récipient également en matière plastique comprenant à sa partie supérieure une collerette périphérique, du type "couvercle rentrant" c'est à dire assurant l'obturation du récipient par pénétration de la partie centrale du couvercle à l'intérieur du récipient.COWERCLE FOR PLASTIC CONTAINER
The subject of the present invention is a plastic cover, in particular for a container also made of plastic, comprising at its upper part a peripheral flange, of the "re-entrant cover" type, that is to say ensuring the closure of the container by penetration of the part. center of the lid inside the container.

Les couvercles de ce type sont connus et largement utilisés.Lids of this type are known and widely used.

Mais en raison de l'augmentation des cadences de production, il est nécessaire que ces couvercles puissent être empilés à la fabrication et surtout soient aisément dépilables lors de la fermeture des récipients. Ces opérations ne peuvent être pratiquement faites que par des moyens mécaniques pour respecter les cadences imposées. Il faut donc que les couvercles présentent une configuration telle qu'ils puissent être empilés mécaniquement avec une bonne stabilité de la pile ce qui permet une extraction mécanique du couvercle supérieur de la pile et sa pose ultérieure sur un récipient par des moyens mécaniques.But due to the increase in production rates, it is necessary that these covers can be stacked during manufacture and above all are easily unstackable when the containers are closed. These operations can only be practically done by mechanical means to respect the imposed rates. It is therefore necessary that the covers have a configuration such that they can be stacked mechanically with good stability of the stack which allows mechanical extraction of the upper cover of the stack and its subsequent installation on a container by mechanical means.

Or, lorsqu'on superpose deux couvercles du type ci-dessus, l'air se trouvant, à l'origine, entre la paroi supérieure du couvercle inférieur et la paroi inférieure du couvercle supérieur est chassé et les couvercles demeurent agglutinés l'un à l'autre ce qui ne permet pas de les dépiler mécaniquement.However, when two covers of the above type are superimposed, the air originally located between the upper wall of the lower cover and the lower wall of the upper cover is expelled and the covers remain agglutinated one by one. the other which does not allow to mechanically unstack them.

Pour remédier à cet inconvénient, il a déjà été proposé de former entre le rebord du couvercle et le fond se trouvant au-dessous du niveau dudit rebord, une rainure périphérique permettant de pallier cet inconvénient, les couvercles reposant sur deux zones circulaires respectivement une zone intérieure constituant l'un des bords de la rainure et une zone extérieure constituée par la paroi reliant la rainure au rebord. Mais la rainure a nécessairement une largeur assez importante ce qui réduit la surface du fond qui constitue la zone imprimable de décoration.To overcome this drawback, it has already been proposed to form a peripheral groove between the rim of the cover and the bottom located below the level of said rim, making it possible to overcome this drawback, the lids resting on two circular zones respectively a zone inner constituting one of the edges of the groove and an outer zone formed by the wall connecting the groove to the edge. However, the groove necessarily has a fairly large width, which reduces the surface of the background which constitutes the printable decoration area.

La présente invention a pour objet de remédier aux inconvénients ci-dessus et de proposer un couvercle à large surface de décoration présentant une bonne stabilité des piles de couvercles, le dépilage de ceux-ci étant réalisé très facilement par une voie mécanique, l'empilage des pots remplis étant également très stable.The object of the present invention is to remedy the above drawbacks and to propose a cover with a large decorative surface having good stability of the stacks of covers, the unstacking of the latter being very easily achieved by mechanical means, stacking filled pots are also very stable.

Selon l'invention, le couvercle pour récipient à collerette, notamment en matière plastique, comprenant une surface centrale et un rebord surélevé au-dessus de ladite surface centrale permettant l'application du couvercle sur la collerette, une rainure périphérique étant formée entre le fond du couvercle et le rebord, est caractérisé en ce que la rainure présente une hauteur égale à la hauteur du rebord au-dessus du fond du récipient, le fond de la rainure étant d'une largeur supérieure à la largeur d'entrée de la rainure.According to the invention, the lid for a container with a collar, in particular made of plastic, comprising a central surface and a raised rim above said central surface allowing the application of the lid to the collar, a peripheral groove being formed between the bottom of the cover and the rim, is characterized in that the groove has a height equal to the height of the rim above the bottom of the container, the bottom of the groove being of a width greater than the entry width of the groove .

Ainsi, dans le cas d'un empilage de couvercles, les deux bords latéraux de la rainure constituent un étai, qui évite tout écrasement de la pile et par suite, autorise un dépilage aisé alors que dans la technique antérieure, une pression suffisamment forte pouvait faire glisser le fond de la rainure d'un couvercle dans la rainure du couvercle inférieur ce qui produisait un encliquetage.Thus, in the case of a stack of covers, the two lateral edges of the groove constitute a forestay, which avoids any crushing of the stack and consequently, allows easy unstacking whereas in the prior art, a sufficiently strong pressure could slide the bottom of the groove of a cover into the groove of the lower cover which produced a click.

D'autres caractéristiques et avantages de la présente invention apparaîtront au cours de la description qui va suivre d'un mode particulier de réalisation, donné uniquement à titre d'exemple non limitatif, en regard des figures qui représentent
- La figure 1, en vue de côté un couvercle selon l'invention
- la figure 2, le même couvercle en vue par-dessus ;
- la figure 3, une vue en coupe par un plan vertical d'un
empilage de couvercles ;
- la figure 4, du gerbage de deux récipients revêtus de
couvercles selon l'invention, en demi-coupe.Other characteristics and advantages of the present invention will appear during the following description of a particular embodiment, given solely by way of nonlimiting example, with reference to the figures which represent
- Figure 1, in side view a cover according to the invention
- Figure 2, the same cover seen from above;
- Figure 3, a sectional view through a vertical plane of a
stacking covers;
- Figure 4, the stacking of two containers coated with
covers according to the invention, in half-section.

Sur les figures 1 et 2, on voit que le couvercle comprend un rebord 1, au-dessous duquel se trouve une paroi latérale 2 reliant le rebord 1 au fond du récipient 3, et au-dessous du couvercle une rainure 4. De préférence, une languette de préhension 5 est prévue sur le rebord 2 dont la forme générale est circulaire dans l'exemple représenté. On retrouve ces éléments sur la coupe partielle de la figure 3.In FIGS. 1 and 2, it can be seen that the cover comprises a rim 1, below which there is a side wall 2 connecting the rim 1 to the bottom of the container 3, and below the cover a groove 4. Preferably, a gripping tab 5 is provided on the rim 2 whose general shape is circular in the example shown. We find these elements on the partial section of Figure 3.

Le rebord 1 est réuni au fond 3 par une face latérale 2 qui est sensiblement parallèle à l'axe du récipient. Il est possible de prévoir un angle de dépouille d'environ 3 . The rim 1 is joined to the bottom 3 by a lateral face 2 which is substantially parallel to the axis of the container. It is possible to provide a draft angle of approximately 3.

Entre le fond 3 et la surface latérale 2, est formée une rainure formant saillie vers le bas du couvercle désignée d'une manière générale par la référence 4. La rainure 4 comprend deux parois latérales 41, 42 réunies par un fond 43. Selon une caractéristique de l'invention, le fond 43 est d'une largeur supérieure à l'ouverture d'entrée 32 de la rainure. Les parois latérales 41 et 42 peuvent, par exemple, être inclinées par rapport à l'axe du couvercle et avec des angles égaux respectivement à 10 pour 42 et à 60 pour 41. Cette rainure est, de préférence, formée par un piston extensible du type décrit dans le brevet français FR-A-2 602 712 destiné à réaliser des fonds pistonnés pincés pour les récipients eux-mêmes. Between the bottom 3 and the side surface 2 is formed a groove projecting downward from the cover generally designated by the reference 4. The groove 4 comprises two side walls 41, 42 joined by a bottom 43. According to a characteristic of the invention, the bottom 43 is of a width greater than the inlet opening 32 of the groove. The side walls 41 and 42 can, for example, be inclined relative to the axis of the cover and with angles equal to 10 for 42 and 60 for 41 respectively. This groove is preferably formed by an extendable piston of the type described in French patent FR-A-2 602 712 intended to produce plucked piston ends for the containers themselves.

On voit sur la figure 3 que le couvercle supérieur repose sur le couvercle intérieur d'une pile d'une part, par l'angle formé entre les parois 2 et 3, et d'autre part, par le fond 43. Il résulte de la rainure 4 une forte résistance à l'écrasement, cette résistance étant donnée par la proximité des parois 41 et 42. En raison des différences de dimensions entre le fond 43 et l'ouverture d'entrée 32 de la rainure 4, le fond 43 ne peut pas pénétrer dans l'ouverture d'entrée 32 du récipient inférieur.We see in Figure 3 that the upper cover rests on the inner cover of a stack on the one hand, by the angle formed between the walls 2 and 3, and on the other hand, by the bottom 43. It follows from the groove 4 has a high resistance to crushing, this resistance being given by the proximity of the walls 41 and 42. Due to the differences in dimensions between the bottom 43 and the inlet opening 32 of the groove 4, the bottom 43 cannot enter the inlet opening 32 of the lower container.

Comme cela apparaît sur la figure 4 qui représente en demicoupe deux récipients, munis de couvercles, en position de gerbage ou d'empilement, la configuration du couvercle C permet également d'assurer un bon empilage des récipients remplis présentant la rigidité nécessaire. Le fond d'un récipient rempli repose sur le fond 3 du couvercle C, au voisinage de la rainure 41, 42, 43 ce qui lui confère une bonne résistance en flexion.As shown in FIG. 4 which shows in half-cut two containers, provided with lids, in stacking or stacking position, the configuration of the cover C also makes it possible to ensure good stacking of the filled containers having the necessary rigidity. The bottom of a filled container rests on the bottom 3 of the cover C, in the vicinity of the groove 41, 42, 43 which gives it good flexural strength.

Bien entendu, la présente invention n'est pas limitée à la forme circulaire du couvercle, mais peut être mise en oeuvre avec une forme quelconque, par exemple carrée, de celui-ci, et il va de soi que de nombreuses variantes peuvent être apportées, notamment par substitution de moyens techniques équivalents, sans sortir pour cela du cadre de l'invention. Of course, the present invention is not limited to the circular shape of the cover, but can be implemented with any shape, for example square, thereof, and it goes without saying that many variants can be made , in particular by substitution of equivalent technical means, without departing from the scope of the invention.
