Definitions

  • the present invention relates to a disposable safety closure device.
  • a closure device comprising, on the one hand, a stopper fixed to the neck of a container, closed by a cover and provided with a tongue of tearing projecting from the side opposite to the container and serving to irreversibly remove the cover of the stopper, and, on the other hand, a part covering the tear-off tab and comprising a circular skirt.
  • This last piece is a plugging cap also comprising means ensuring the seal between itself and the plug.
  • closures used are of the snap-on or ultrasonic welded type, but none of them is designed to resist opening by a young child. However, these closure devices avoid any possibility of recapping the container after the first opening.
  • closure devices are of the "child proof” type, that is to say have a structure such that the opening of the fitted container can only be achieved by coordination of several movements.
  • the object of the invention is to provide a safety closure device, that is to say a device which cannot be opened easily by a young child, or opened accidentally, and which is for single use, it that is to say who can no longer ensure the closure of the container that it equips after first opening.
  • the cap covering the cap ensures the safety of the closure of the container, since this cap can only be removed from the cap after having achieved its angular positioning in a precise manner, so that the returns which it comprises are in alignment with the openings made in the lip of the cap.
  • the stopper cannot be used for closing the container, after a first opening, since this first opening results in the separation of the part of the stopper comprising the closure cap and the part of the stopper mounted on the neck. of the container.
  • the tear-off tongue extends in the extension of the tubular part, over a part of the periphery thereof.
  • the safety cap comprises, at the free end of the circular skirt, an inward return which, covering the upper edge of the tongue, has an open central part.
  • cap while ensuring excellent protection of the tear-off tab of the cap, leaves, by its open central part, direct vision of the central part of the cap. This allows a consumer wishing to buy the container equipped with this device, to instantly and visually check that the closure cap has not been damaged.
  • the closure device according to the invention designated by the general reference 2 in FIG. 1, comprises a plug 3 and a safety cap 4 intended to be fixed over the plug.
  • the plug 3 includes a hollow interlocking profile 5 intended to come cover the upper edge 6 of the neck 7 of a container.
  • the attachment of the hollow socket 5 on the neck of the container is carried out by means of shoulder 8 and complementary boss 9, formed respectively on the neck 7 and on the cap.
  • This assembly is such that it is irreversible.
  • a shoulder 10 which the neck 7 includes is flush with the lower end of the cap.
  • the stopper is extended outwards by a tubular part 12, the free end of which is closed by a cover 13.
  • the tubular part 12 comprises a thinned zone of material 14, capable of to be torn apart.
  • a tongue 15 is provided which projects from the side opposite the neck of the container 7, this tongue 15 extending in the extension of the tubular part, over a part of the periphery thereof.
  • the tubular part 15 comprises a lip 16 projecting radially outwards, in which are cutouts 17 of determined shape. As shown in the drawing and in particular in Figure 6, the shape of these cutouts is not regular, and their angular distribution is also not regular.
  • the safety cap 4 comprises, for its part, a circular skirt 18 surrounding the tubular part 12 of the stopper and covering the tear-off tab 15.
  • the skirt 18 has a return 19 inwards which covers the tab, the inner edge of this return defining a central opening 20.
  • the end of the skirt 18 located on the side of the neck of the container has a flange 22 facing radially outward, is intended to come to bear on the lip 16 of the plug.
  • This rim 22 is extended on the side of the container neck by a part 23 in the form of a cylindrical skirt with a height at least equal to the thickness of the lip 16.
  • the free end of the skirt 23 has at least one return 24 inward, the number and shape of the returns 24 corresponding to those of the cutouts 17 formed in the lip 16 of the plug.
  • These returns 24 are capable of passing under the lip 16 to form attachment members of the safety cap vis-à-vis the cap. It appears from this structure that in the closed position of the container, the cap is hung on the stopper and occupies an angular position with respect thereto. To make the opening of the container, it is therefore necessary to bring the cap 4 in an angular position such that the returns 24 which it comprises are arranged opposite the cutouts 17 of the lip 16. This angular positioning can be facilitated by coincidence of marks, formed respectively on the cap and on the cap. Once this coincidence has been achieved, the cap 4 is removed by axial displacement.
  • FIGS. 4 and 5 show the cap 3 respectively before opening, and after opening. It emerges from this structure that after opening the container can no longer be closed.
  • the invention brings a great improvement to the existing technique by providing a disposable closure device, and of safety since its structure avoids any accidental opening.
