Description

De nombreux récipients métalliques et tout particulièrement les pots ou boîtes contenant de la peinture ou analogue sont généralement fermés par un bouchon métallique enfoncé par pression dans l'ouverture du récipient. Or, il est bien connu que ces bouchons posent de nombreux problèmes car ils doivent avoir des dimensions précises pour assurer une étanchéité efficace et par suite être enfoncés à force de sorte qu'en général ils sont extrêmement difficiles à remettre en place pour l'usager et en outre ont tendance à sauter lorsque le récipient fermé subit un choc.Many metal containers and especially pots or boxes containing paint or the like are generally closed by a metal plug pressed by pressure into the opening of the container. However, it is well known that these plugs pose many problems because they must have precise dimensions to ensure an effective seal and consequently be forced in so that in general they are extremely difficult to replace for the user. and also tend to jump when the closed container is shocked.

L'utilisation, pour la fermeture de ces récipients métalliques, de capsules en matière plastique facilite l'adaptation du bouchon sur l'orifice à obturer, et permet ainsi à l'utilisateur de remettre plus facilement le bouchon en place. Malheureusement cette facilité d'adaptation se traduit rapidement par une déformation permanente de la capsule qui ne permet pas de maintenir une étanchéité durable, ce qui est très grave lorsque le récipient contient des produits sensibles à la pénétration de l'air. Les capsules en matière plastique, de même que les bouchons métalliques, ne peuvent donc être utilisés que pour la fermeture d'orifices de dimension relativement faible.The use, for closing these metal containers, of plastic capsules facilitates the adaptation of the stopper to the orifice to be closed, and thus allows the user to more easily replace the stopper in place. Unfortunately, this ease of adaptation quickly results in a permanent deformation of the capsule which does not make it possible to maintain a lasting seal, which is very serious when the container contains products sensitive to the penetration of air. Plastic capsules, as well as metal caps, can therefore only be used for closing orifices of relatively small size.

La présente invention a pour but de remédier à ces inconvénients en fournissant un bouchon composite qui permette de retrouver une étanchéité efficace quelque soit le nombre d'utilisations et puisse s'adapter à des dimensions d'orifices très diverses tout en étant simple de réalisation.The object of the present invention is to remedy these drawbacks by providing a composite stopper which makes it possible to find an effective seal whatever the number of uses and can adapt to very diverse dimensions of orifices while being simple to produce.

Cette invention est relative à un bouchon composite pour récipient métallique comportant une capsule en matière plastique dont la paroi latérale est munie à sa partie supérieure d'un bourrelet d'appui sur le bord de l'orifice (voir p. ex. EP-A 112 691). Selon l'invention le bouchon comporte, à l'intérieur de cette capsule, un capuchon métallique dont la périphérie est serrée sur l'opercule de la capsule contre sa paroi latérale cylindrique et qui est rendu solidaire de cette dernière.This invention relates to a composite stopper for a metal container comprising a plastic capsule, the side wall of which is provided at its upper part with a support bead on the edge of the orifice (see eg EP-A 112 691). According to the invention, the stopper comprises, inside this capsule, a metal cap whose periphery is clamped on the cap of the capsule against its cylindrical side wall and which is made integral with the latter.

Selon un mode de réalisation, la paroi latérale de la capsule comporte une nervure de verrouillage d'un rebord cylindrique du capuchon métallique. Selon un autre mode de réalisation le capuchon métallique comporte un rebord qui se prolonge sur toute la partie supérieure de la paroi de la capsule et est serti sur le bourrelet d'appui.According to one embodiment, the side wall of the capsule comprises a rib for locking a cylindrical rim of the metal cap. According to another embodiment, the metal cap has a rim which extends over the entire upper part of the wall of the capsule and is crimped onto the support bead.

Dans tous les cas, on constate que le bouchon obtenu présente une rigidité suffisante pour éviter une déformation de la matière plastique susceptible de détruire l'étanchéité. Par contre, cette matière plastique garde suffisamment de souplesse pour s'adapter dans l'orifice à obturer et être ainsi facile à remettre en place de manière efficace.In all cases, it is found that the plug obtained has sufficient rigidity to avoid deformation of the plastic material capable of destroying the seal. On the other hand, this plastic material retains enough flexibility to adapt to the orifice to be closed and thus be easy to replace effectively.

La description ci-dessous de modes de réalisations, donnés à titre d'exemple non limitatif et représentés aux dessins annexés, fera d'ailleurs ressortir les avantages et caractéristiques de l'invention.The description below of embodiments, given by way of nonlimiting example and represented in the appended drawings, will moreover highlight the advantages and characteristics of the invention.

Sur ces dessins :

  • - la Fig. 1 est une vue en perspective avec arrachement partiel d'un bouchon composite selon l'invention ;
  • - la Fig. 2 est une vue partielle à plus grande échelle, en coupe radiale, du bouchon de la Fig 1 ;
  • - la Fig. 3 est une vue analogue à la Fig. 2 d'une variante de réalisation.
In these drawings:
  • - Fig. 1 is a perspective view with partial cutaway of a composite plug according to the invention;
  • - Fig. 2 is a partial view on a larger scale, in radial section, of the plug of FIG 1;
  • - Fig. 3 is a view similar to FIG. 2 of an alternative embodiment.

Le bouchon composite, objet de l'invention, est destiné à la fermeture d'un récipient métallique et tout particulièrement d'un pot ou d'une boîte contenant de la peinture, de l'huile ou autre produit à faible densité. Une telle boîte est indiquée en traits mixtes en 1 sur la Fig. 1. Le bord de l'orifice de la boîte 1 sur lequel vient se fixer le bouchon composite peut être droit ou roulé.The composite stopper, object of the invention, is intended for closing a metal container and more particularly a pot or a box containing paint, oil or other low density product. Such a box is indicated by dashed lines in 1 in FIG. 1. The edge of the orifice of the box 1 on which the composite plug is fixed can be straight or rolled.

Le bouchon 2 est formé par une capsule 4 en matière plastique, par exemple en polyéthyléne, qui comporte une paroi latérale cylindrique 6, terminée à sa partie supérieure par un bourrelet 8 d'appui sur le bord de l'orifice à obturer. Un opercule circulaire 9 forme le fond de la capsule 4, mais est relié à la paroi 6 dans sa partie médian de sorte que le capsule 4 comporte une jupe inférieure 10 de pénétration à l'intérieur de l'orifice à obturer.The stopper 2 is formed by a capsule 4 made of plastic, for example polyethylene, which has a cylindrical side wall 6, terminated at its upper part by a bead 8 bearing on the edge of the orifice to be closed. A circular cover 9 forms the bottom of the capsule 4, but is connected to the wall 6 in its median part so that the capsule 4 has a lower skirt 10 for penetrating inside the orifice to be closed.

Un capuchon 12 en métal est monté à l'intérieur de la capsule 4 de telle manière que sa périphérie soit étroitement serrée contre la partie interne de cette capsule 4. Comme le montre les dessins, le capuchon 12 comporte de préférence une partie centrale cylindrique 14 qui est coaxiale à la paroi latérale 6 de la capsule et est fermée par un fond 16 situé dans le même plan que le bord supérieur du bourrelet 8 ou même légèrement en saillie à l'extérieur de celui-ci. A l'opposé de ce fond 16, le cylindre 14 est solidaire d'une couronne plane 18 qui est étroitement appliquée sur l'opercule 9 et est recourbée pour former un rebord cylindrique 20 parallèle au cylindre 14. Le cylindre 20 est appliqué contre la face interne de la paroi latérale 6 de la capsule. Il est en outre immobilisé par une nervure circulaire 22 de cette paroi de sorte que l'ensemble périphérique formé par le cylindre 20 et la couronne 18 est étroitement appliqué contre la face interne de la capsule en matière plastique 4, et que le capuchon métallique et cette capsule sont rendus solidaires l'un de l'autre.A metal cap 12 is mounted inside the capsule 4 so that its periphery is tightly pressed against the internal part of this capsule 4. As shown in the drawings, the cap 12 preferably comprises a central cylindrical part 14 which is coaxial with the side wall 6 of the capsule and is closed by a bottom 16 located in the same plane as the upper edge of the bead 8 or even slightly projecting outside of it. Opposite this bottom 16, the cylinder 14 is integral with a flat crown 18 which is tightly applied to the cover 9 and is curved to form a cylindrical rim 20 parallel to the cylinder 14. The cylinder 20 is applied against the internal face of the side wall 6 of the capsule. It is also immobilized by a circular rib 22 of this wall so that the peripheral assembly formed by the cylinder 20 and the crown 18 is tightly applied against the internal face of the plastic capsule 4, and that the metal cap and this capsule are made integral with one another.

Lorsqu'un tel bouchon est introduit dans l'orifice à obturer la jupe 10 pénétre à l'intérieur de cet orifice et l'ensemble de la paroi latérale 6 est comprimé pour assurer une étanchéité efficace. Cette paroi latérale ne peut se déformer que d'une manière limitée car elle est solidement maintenue par le capuchon 12 et notamment par ces éléments 18 et 20.When such a plug is introduced into the orifice to be closed, the skirt 10 penetrates inside this orifice and the whole of the side wall 6 is compressed to ensure an effective seal. This side wall can only be deformed in a limited way because it is firmly held by the cap 12 and in particular by these elements 18 and 20.

Bien entendu, la partie inférieure du bourrelet 8 de la capsule peut comporter une ou plusieurs encoches réparties sur sa circonférence de façon à faciliter l'introduction d'un organe mince destiné à amorcer le soulèvement du bouchon lorsque celui-ci doit être retiré. Une telle opération peut en effet être effectuée aussi souvent qui cela est nécessaire, la matière plastique conservant sa souplesse et l'étanchéité étant retrouvée à chaque fois.Of course, the lower part of the bead 8 of the capsule may include one or more notches distributed over its circumference so as to facilitate the introduction of a thin member intended to initiate the lifting of the plug when the latter has to be removed. Such an operation can indeed be carried out as often as necessary, the plastic material retaining its flexibility and sealing being found each time.

Selon une variante de réalisation représentée sur la Fig. 3, la nervure 22 de la paroi latérale 6 de la capsule est supprimée, et le capuchon métallique 12 comporte un rebord périphérique cylindrique 24 qui se prolonge sur toute la surface extérieure du bourrelet 8 et est serti sur ce bourrelet. Le capuchon métallique est ainsi rigoureusement solidaire de la capsule en matière plastique 4 et assure au bouchon composite une rigidité suffisante pour que cette capsule ne puisse se déformer de manière permanente. Dans ce mode de réalisation le bourrelet 8 comporte un épaulement 26 qui vient en appui sur le bord de l'orifice de la boîte 1 pour permettre l'introduction d'un organe mince pour amorcer le soulèvement du bouchon.According to an alternative embodiment shown in FIG. 3, the rib 22 of the side wall 6 of the capsule is removed, and the metal cap 12 has a cylindrical peripheral rim 24 which extends over the entire outer surface of the bead 8 and is crimped onto this bead. The metal cap is thus strictly secured to the plastic capsule 4 and provides the composite plug with sufficient rigidity so that this capsule cannot be deformed permanently. In this embodiment the bead 8 has a shoulder 26 which bears on the edge of the orifice of the box 1 to allow the introduction of a thin member to initiate the lifting of the plug.

Quel que soit le mode de réalisation choisi on constate que le bouchon composite conserve son éfficacité même après un nombre important de manipulations et que par suite, l'invention est adaptée aussi bien à la fermeture des orifices de petite dimension qu'à celle des orifices importants. Le bouchon décrit peut donc être utilisé pour fermer un orifice ménagé dans une partie de la surface du récipient ou éventuellement pour fermer l'orifice constitué par la totalité de cette surface comme le montre la Fig. 1. La forme du bouchon facilite l'empilage des boîtes ainsi obturées les unes au-dessus des autres soit que les fonds comportent un rebord périphérique qui s'emboite tout autour du bourrelet 8 de la capsule soit qu'ils comportent une nervure susceptible de s'emboîter entre la paroi cylindrique 14 du capuchon et la paroi latérale 6 de la capsule. En variante, le fond 16 fermant la partie centrale cylindrique 14 du capuchon 12 peut être légèrement en saillie par rapport au plan du bord supérieur du bourrelet 8 de manièe à s'emboîter dans une rainure située dans le fond de la boîte immédiatement supérieure.Whatever the embodiment chosen, it can be seen that the composite stopper retains its effectiveness even after a significant number of manipulations and that consequently, the invention is suitable for both closing small orifices and that of orifices. important. The stopper described can therefore be used to close an orifice formed in part of the surface of the container or possibly to close the orifice formed by the whole of this surface as shown in FIG. 1. The shape of the stopper makes it easier to stack the boxes thus closed one above the other, either because the bottoms have a peripheral rim which fits all around the bead 8 of the capsule, or whether they have a rib capable of fit between the cylindrical wall 14 of the cap and the side wall 6 of the capsule. As a variant, the bottom 16 closing the cylindrical central part 14 of the cap 12 can be slightly projecting with respect to the plane of the upper edge of the bead 8 so as to fit into a groove located in the bottom of the box immediately above.

Le fond du capuchon métallique 16 fournit en outre une surface plane et visible qui constitue un excellent support pour le marquage ou autre ou même pour la présentation de la couleur de la peinture contenue.The bottom of the metal cap 16 also provides a flat and visible surface which constitutes an excellent support for marking or other or even for the presentation of the color of the paint contained.
