Abstract

The stopper comprises a top (1) with a tapping (2). A cap (3) which rotates freely in one direction on the screw top has an opening (4) in its top (5). An elastic ring (6) which is housed in a groove in the internal lateral face of the cap mates with the lower edge (7) of the top so as to prevent the top from leaving the cap . The upper face of the top has a dihedral part (8) constituting a male part. The cap has an upper sleeve (9), having the same axis (XX') as the cap, whose two bosses (10) overhang the male part. The key for the removal of the stopper has a female part of complementary form to the dihedral part of the male top and indentations conjugate with the bosses.

Description

La présente invention se rapporte aux bouchons, et notamment à ceux comportant un couvercle taraudé venant se visser sur le col fileté d'un récipient.The present invention relates to stoppers, and in particular to those comprising a threaded cover which is screwed onto the threaded neck of a container.

Les citernes de gaz sont munies d'une valve de remplissage permettant le transfert du produit, généralement à partir d'un camion-citerne itinérant ; le mécanisme de cette valve est protégée des intempéries par un bouchon constitué d'un simple couvercle taraudé. Il y a donc un risque pour l'utilisateur ou une personne non habilitée à solliciter le clapet de la valve de remplissage avec des conséquences graves; il est également possible à un distributeur peu scrupuleux de livrer du produit sans que la société propriétaire de la citerne en soit avertie en dévissant le bouchon et en emplissant la citerne du produit.The gas tanks are fitted with a filling valve allowing the transfer of the product, generally from a traveling tank truck; the mechanism of this valve is protected from the weather by a plug made up of a simple threaded cover. There is therefore a risk for the user or a person not authorized to apply the filling valve valve with serious consequences; it is also possible for an unscrupulous distributor to deliver product without the company owning the tank being notified by unscrewing the cap and filling the tank with product.

Au FR-A-1207211, on décrit un bouchon comprenant une coiffe, coiffant fou, au moins dans le sens de rotation, le couvercle et ayant une ouverture ménagée en son sommet et des moyens destinés à empêcher le couvercle de sortir de la coiffe. La face supérieure du couvercle comporte une partie mâle ou femelle accessible, par l'ouverture, à une clé munie d'une partie femelle ou mâle, de forme complémentaire de la partie mâle ou femelle, assurant une solidarisation en rotation de la clé et du couvercle.In FR-A-1207211, a stopper is described comprising a cap, loose cap, at least in the direction of rotation, the cover and having an opening formed at its top and means intended to prevent the cover from coming out of the cap. The upper face of the cover has a male or female part accessible, through the opening, to a key provided with a female or male part, of a shape complementary to the male or female part, ensuring a rotational securing of the key and the lid.

On ne peut ainsi dévisser le couvercle taraudé du col du récipient qu'en faisant tourner le couvercle au moyen de la clé, parce que toutes les autres parties du couvercle sont entourées de la coiffe, en étant donc inaccessibles, et parce que la rotation de la coiffe, au moins dans le sens du dévissage du couvercle taraudé, ne se traduit pas par la rotation de ce couvercle taraudé, puisque la coiffe est montée folle au moins dans ce sens de rotation sur le couvercle.One can thus unscrew the threaded cover from the neck of the container only by rotating the cover by means of the key, because all the other parts of the cover are surrounded by the cover, thus being inaccessible, and because the rotation of the cover, at least in the direction of unscrewing the threaded cover, does not result in the rotation of this threaded cover, since the cap is mounted loose at least in this direction of rotation on the cover.

L'invention vise à augmenter encore l'inviolabilité, tout en facilitant l'ouverture par une personne munie de la clé. Le bouchon suivant l'invention est caractérisé à la revendication 1.The invention aims to further increase the inviolability, while facilitating opening by a person provided with the key. The stopper according to the invention is characterized in claim 1.

La partie mâle ou femelle de la face supérieure du couvercle est ainsi rendue encore moins accessible si l'on ne dispose pas d'une clé. Il faut donc disposer d'une clé qui non seulement s'adapte à la partie mâle ou femelle du couvercle, mais également qui est susceptible de passer dans le manchon en s'adaptant à la forme des bossages. En outre, ces bossages constituent des faces de contact de la clé avec la coiffe de sorte que, après que la clé a été appliquée sur la partie mâle ou femelle et a tourné légèrement, le paneton de la clé vient sous le bossage, en sorte qu'il est immobilisé en translation suivant l'axe du bouchon et que l'utilisateur n'a plus qu'à exercer un effort de rotation, sans avoir à pousser la clé vers le bas en permanence. La partie femelle comporte une échancrure conjuguée du bossage.The male or female part of the upper face of the cover is thus made even less accessible if one does not have a key. It is therefore necessary to have a key which not only adapts to the male or female part of the cover, but also which is capable of passing through the sleeve while adapting to the shape of the bosses. In addition, these bosses constitute contact faces of the key with the cap so that, after the key has been applied to the male or female part and has turned slightly, the key bit comes under the boss, so that it is immobilized in translation along the axis of the plug and that the user only has to exert a rotational force, without having to push the key down continuously. The female part has a conjugate notch in the boss.

Suivant un mode de réalisation, les moyens destinés à empêcher le couvercle de sortir de la coiffe sont prévus sur la face latérale intérieure de la coiffe de manière à être eux aussi inaccessibles. Ces moyens peuvent être notamment un jonc élastique (circlip).According to one embodiment, the means intended to prevent the cover from coming out of the cap are provided on the inner lateral face of the cap so as to be also inaccessible. These means can in particular be an elastic ring (circlip).

Dans un mode de réalisation, la coiffe coiffe le couvercle avec jeu. Dans un autre mode de réalisation, elle le coiffe avec interposition d'un cliquet, n'assurant la solidarisation en rotation de la coiffe et du couvercle que dans le sens du vissage du bouchon sur le col de la citerne.In one embodiment, the cap covers the cover with play. In another embodiment, it covers it with the interposition of a ratchet, ensuring the rotational fastening of the cap and the cover only in the screwing direction of the stopper on the neck of the tank.

Aux dessins annexés, donnés uniquement à titre d'exemple :

  • la figure 1 est une vue en coupe éclatée d'un bouchon et d'une partie d'une citerne ;
  • la figure 2 est une vue en plan correspondant à la figure 1;
  • la figure 3 est une vue partielle en élévation d'une clé ;
  • et les figures 4 à 6 sont des vues de dessous de plusieurs panetons de clé.
In the accompanying drawings, given solely by way of example:
  • Figure 1 is an exploded sectional view of a plug and part of a tank;
  • Figure 2 is a plan view corresponding to Figure 1;
  • Figure 3 is a partial elevational view of a key;
  • and Figures 4 to 6 are bottom views of several key panons.

Le bouchon suivant l'invention est destiné à se visser sur le filetage F du col C d'une citerne qui n'est pas autrement représentée.The cap according to the invention is intended to be screwed onto the thread F of the neck C of a tank which is not otherwise shown.

Le bouchon comporte un couvercle 1 ayant un taraudage 2. Une coiffe 3 coiffe fou le couvercle 2. Cette coiffe est munie d'une ouverture 4 ménagée en son sommet 5. Un jonc 6 élastique logé dans une rainure de la face latérale intérieure de la coiffe 3 coopère avec le bord 7 inférieur du couvercle de manière à empêcher celui-ci de sortir de la coiffe 3 après qu'il y a été introduit.The cap has a cover 1 having a thread 2. A cap 3 for the cover 2. This cap is provided with an opening 4 formed at its top 5. An elastic rod 6 housed in a groove on the inner lateral face of the cap 3 cooperates with the lower edge 7 of the cover so as to prevent the latter from coming out of the cover 3 after it has been introduced therein.

La face supérieure du couvercle comporte une partie 8 diédrique constituant une partie mâle. La coiffe comporte un manchon 9 supérieur de même axe XX' que la coiffe, et dont deux bossages 10 sont en surplomb de la partie 8.The upper face of the cover has a dihedral part 8 constituting a male part. The cap has an upper sleeve 9 of the same axis XX 'as the cap, and of which two bosses 10 are overhanging the part 8.

La clé utilisée pour ôter le bouchon est représentée aux figures 3 à 4. Elle comprend essentiellement une poignée 12, une tige 13 et un paneton 14. La face inférieure du paneton constitue une partie femelle 15 comportant des échancrures 16 conjuguées des bossages 10.The key used to remove the stopper is shown in FIGS. 3 to 4. It essentially comprises a handle 12, a rod 13 and a bit 14. The underside of the bit constitutes a female part 15 comprising notches 16 conjugated with bosses 10.

Pour ôter le bouchon, on introduit la clé par le paneton 14 en faisant coïncider les bossages 10 et les échancrures 16 dans l'ouverture de la coiffe jusqu'à ce que la partie femelle 15 vienne coopérer par complémentarité de forme avec la partie 8 mâle. Par une légère rotation, on engage le paneton 14 sous les bossages 10. En continuant à tourner, on peut dévisser le couvercle 1 taraudé du filetage F.To remove the plug, the key is introduced through the bit 14, making the bosses 10 and the notches 16 coincide in the opening of the cap until the female part 15 comes to cooperate by form complementarity with the male part 8. . By a slight rotation, the blade 14 is engaged under the bosses 10. Continuing to turn, you can unscrew the threaded cover 1 of the thread F.

Aux figures 5 et 6, les échancrures 16 sont disymétriques et/ou disposées disymétriquement.In Figures 5 and 6, the notches 16 are asymmetrical and / or arranged asymmetrically.
