Definitions

  • the present invention relates to a plugging device with a rotating cap.
  • This type of closure device is, for example, constituted by a dispenser cap comprising a cap body permanently mounted on a container with elastically deformable walls, more especially intended to contain semi-liquid or pasty products, this cap body mounted so final on the neck of the container having a central boss capable of sealingly sealing a central opening formed in the cap in a certain position thereof, and of delimiting with this opening in another angular position of the cap a passage for the outlet of the product in the container.
  • a closure device of this type is described in particular in French patent application FR-A-2 600 978 in the name of the applicant.
  • the device described in this document comprises a cap capable of being pivoted relative to the body of the plug when it is pivoted relative to the latter in order to clear a passage for discharging the product.
  • this device is entirely satisfactory as regards its structure and reliability, it has the disadvantage of being able to be opened easily, by simple rotation of the cap relative to the body of the stopper.
  • the present invention specifically aims to provide a plugging device with a rotating cap requiring, for its opening, the simultaneous production of two completely separate movements.
  • the device which it relates to of the type in which the cap comprises a cylindrical skirt, extending by a frustoconical part, the connection zone between the cylindrical skirt and the frustoconical part being situated substantially at the level of a shoulder, arranged in a plane perpendicular to the axis of the closure device and formed in a body constituted by the body of the stopper, or by the container to be fitted itself, is characterized in that in this connection zone is provided at least one tongue delimited by two vertical slits and a horizontal slit the horizontal edge of the tongue delimited by the slit being provided, on the inside side of the cap with an extension forming a notch extending substantially vertically and arranged, in the closed position of the cap, adjacent to a notch belonging to the body, located in its extension in the direction of rotation of the cap, each tongue being elastically deformable to allow a radial offset of the notch corresponding to a value at least equal to the width of the notches belonging to the body.
  • the cap When the closure device is in the closed position, the cap is blocked in rotation, by pressing that takes each notch of a tongue which it comprises, against a corresponding notch formed in the body. Therefore to achieve the opening of the device, it is first necessary to exert a radial action on each tab, to make it escape the corresponding notch of the body, before exerting a rotating unscrewing movement.
  • each notch formed on the body projects from the shoulder perpendicular to the axis of the body, upwards and close to the outer edge of the shoulder.
  • the notch that comprises the extension of each tongue is profiled from front to rear in the direction of screwing, its front end being thinned.
  • each notch that the body has is profiled inversely to that of the corresponding notch of the cap, its thinned edge being offset inwards relative to its longitudinal center line.
  • each tongue is delimited by two vertical slots, and a horizontal slot, at its upper end, this upper edge being provided with an extension, of orientation parallel to the axis of the cap.
  • the cap has two diametrically opposite tongues. This last characteristic makes the opening movement even more complex since it is necessary to exert pressure not on one tongue, but on two tongues simultaneously.
  • This closure device is for example intended to equip a container whose neck 2 is shown in Figures 2 to 4, made of an elastically deformable synthetic material, whose elastic deformation allows the expulsion of the pasty or semi-liquid product it contains under pressure from the user.
  • the body 3 of the plug On the neck 2 is permanently mounted the body 3 of the plug, which comprises a part 4 intended to fit together with sealing on the neck 2.
  • the fixing is carried out by means of complementary bosses 5, 6 formed respectively on the neck and on the body of the plug, the rotation lock being produced by means of notches 7, 8 respectively formed on the neck and on the body of the plug.
  • the body 3 of the plug has, given its interlocking part, a shoulder 9 with an axis perpendicular to the axis of the body.
  • the body of the plug continues with a cylindrical part comprising beads 10 acting like a thread. This cylindrical part is connected by lugs 12 to a central end piece 13 from which protrudes a boss 14. Between the lugs 12 are openings 15 for the passage of the product.
  • a cap 16 On the body 3 of the stopper is intended to be mounted a cap 16.
  • This cap 16 comprises a cylindrical skirt 17 intended to come to cover the lower end of the body of the stopper, and capable of being fitted with a non-tamper-evident safety belt. shown in the drawing.
  • This cylindrical skirt 17 comprises lugs 18 cooperating with ramps 19 that the body of the plug comprises to achieve an axial displacement of the cap relative to the body when the cap is rotated in a direction of unscrewing.
  • This cylindrical part 17 forming a skirt is extended upwards by a frustoconical part 20.
  • This frustoconical part, 20 comprises, projecting inwards, a cylindrical part, comprising beads 22 intended to cooperate with the beads 10 of the body of the plug. to achieve an axial displacement of the cap with respect to the body to pass from the open position to the closed position.
  • the end of the cap has an opening 23 intended to cooperate with the central boss 14 to respectively close the container when the opening comes to fit on the central boss, or the opening of the latter when said opening 23 is clear of the boss.
  • the cap 16 comprises two diametrically opposite tongues 24, each tongue disposed substantially in the connection zone between the skirt 17 and the frustoconical part 20 being delimited, by two vertical slots 25 and by an upper horizontal slot 26 At its upper edge delimited by the slot 26, the tongue 24 is equipped with a vertical extension 27.
  • This extension 27 is situated substantially at the level of the outer edge of the shoulder 9 of the body 3.
  • the lower end of the extension 27 forms a notch 28, the front end of which in the direction of screwing, is profiled, that is to say has a thinned edge 29.
  • Each tab 24 is associated with a notch 30 formed on the body of the plug. 3, projecting upwards from the shoulder 9.
  • This notch 30 is arranged in the extension of the notch 28 of the tongue when the device is in the closed position. Unlike notch 28, this notch 30 is profiled inversely, its end situated opposite the end 29 forming a thinned edge 32, and facing inward.
  • the invention brings a great improvement to the existing technique by providing a closure device of simple design, the opening of which requires the coordination of several movements, which avoids any risk of accidental opening or by a young child.
  • the plugging device may not include a plug body and a cap, but the cap could be mounted directly on the neck of the container which, for its part, would have locking notches without being removed. however within the scope of the invention.
