Definitions

  • 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.
  • 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.
  • a stopper 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.
  • 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.
  • 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.
  • 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.
  • 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).
  • 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.
  • 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.
  • the cap has a cover 1 having a thread 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.
  • 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.
  • FIGS. 3 to 4 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.
  • 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. .
  • the blade 14 is engaged under the bosses 10. Continuing to turn, you can unscrew the threaded cover 1 of the thread F.
  • the notches 16 are asymmetrical and / or arranged asymmetrically.
