Definitions

  • the invention relates to a hinged stopper device for closing a container such as a bottle, flask or the like.
  • a hinged stopper that is to say a device molded from a plastic part comprising a first part provided with '' an outlet opening and intended to be fixed to the container and a second part or cap connected to the first part by a film hinge in said plastic material, for example polypropylene whose excellent resistance to bending allows the production of hinges extremely robust likely to undergo a very large number of folds without any notable alteration.
  • Hinged stopper devices for closing containers of this type are disclosed, for example, in FR-A-2 380 195, where the means constituting the hinge itself are relatively bulky and projecting considerably from the external surface. of the device which eliminates their use for certain applications, for example for closing containers of the type of those used for the packaging of pharmaceuticals, cosmetics, or the like.
  • the embodiments described include means for blocking the cap relative to the part fixed to the container, so that if they are suitable for opposing the unwanted opening, by children, of the container that they equip, they are of a structure too complex to be associated with receptacles for which the condition which has just been recalled is less imperative.
  • an object of the invention to provide a hinged stopper device for closing containers such as bottles, flasks, tubes or the like, which overcomes the above-mentioned drawbacks of known devices.
  • a hinged cap device comprising a first part provided with an opening so and suitable for being fixed to the container and a second part or cap provided with means for closing said opening and connected to said first part by a film hinge with elastic effect is characterized in that the single film hinge comprises end zones - considered in the axial direction of the hinge - which are shaped according to portions of spherical surfaces.
  • film hinge is meant here a hinge, the two parts of which are movable relative to each other are connected to each other by a thin thickness or film of plastic material, which protects the pivot axis, as otherwise customary in the technique of stoppers, binders or folding boxes molded in one piece which make use of such hinges.
  • the middle zone between said portions of spherical surfaces has a substantially rectangular plane contour, with long sides directed parallel to the axis of the hinge.
  • the portions of spherical surfaces are limited by a substantially parallel plane lele to the free edge of the cap, in the molding condition of the device, while said plane makes an angle of substantially 90 ° relative to its molding condition, in the closed condition of the device.
  • the thickness of the film constituting the hinge is the same, in the middle zone and in the end zones.
  • the film is of variable thickness, advantageously thicker in the middle zone than in the partly spherical end zones.
  • the first part fixed to the container comprises an end lip and the central zone of the hinge is connected on one of the faces to the side wall of the cap and to the side wall of said lip by rounded edges while the connection of said zone to said walls takes place by chamfers on its other face.
  • the closure device according to the invention for closing a container such as a bottle, a flask or a tube, T, FIG. 2, essentially comprises a first part 11 intended to be fixed on the container T by screwing a skirt 12 on the end piece e of the tube and a second part or cap 13 connected to the first part by a hinge 14 of the "film hinge" type. that is to say made by an area of small thickness of the plastic material constituting the device, for example polypropylene whose excellent resistance to bending allows the realization of this type of hinge.
  • the skirt 12 which has on its outer surface two diametrically opposite ribs 12a and 12b forming stops, depends on a frustoconical cap 15 whose base of smaller diameter is pierced with an opening 16 for the passage of the product contained in the container T , while at the base of larger diameter is connected a wall 17 with very small conicity 17 whose free end part is connected by a shoulder 18 to a cylindrical lip with circular cross section 19.
  • the cap 13 is shaped as follows a frustoconical bowl also with very low conicity and whose profile of the internal face of the side wall 20 is conjugated with that of the wall 17, while the external diameter of the free edge 20a corresponds to that of the lip 19.
  • a bottom 21 slightly curved towards the inside of the bowl, carries in its center a stud 22 of combined shape and dimensions of the opening 16 which it is intended to close in the closed condition of the device.
  • the hinge 14, illustrated more precisely in FIGS. 3 to 6, is formed at the periphery of the lip 19 and in the vicinity of the end of the wall 20 distant from the bottom 21.
  • the film hinge 14 comprises a central zone 30, FIGS. 1, 3 and 5 substantially planar and with a somewhat rectangular outline with long sides 32, 33 directed tangentially to the cylindrical or almost cylindrical surfaces constituting the lip 19 and the wall 20 and short sides parallel to the overall plane of symmetry of the device, as shown by line II-II in Figure 1.
  • central zone 30 are connected to the longitudinal ends of the rectangle (the direction of the long sides of which defines the axis of the hinge) zones 35 and 36 shaped according to portions of spherical surfaces bounded by a plane parallel to that of the free edge 20a of the cap 13, in the device molding condition, and whose radius is slightly greater than the width of the middle zone 30 in the plane of symmetry II-II of the device.
  • the zones 35, 36 have the same thickness as that of the zone 30.
  • the zones 35 and 36 are thinner than the zone 30.
  • the latter is connected to the external face of the wall 20 by a rounded 40, to the external face of the lip 19 by the same rounded 41 and by chamfers 43 and 44 at free edge 20a of the cap 13, on the one hand and, on the face 45 of the shoulder 18 which is substantially coplanar with said free edge in the condition of 180 ° opening of the stopper device, which is that shown on the Figures 1 and 2, on the other hand.
  • the injection molding of the polypropylene device takes place from part 10, so that a high resistance is obtained for the hinge, both in its central zone 30 and in its end zones in part. spherical, the latter contributing to the elimination of any notch phenomenon detrimental to the resistance of the device which is further increased by the orientation of the constituent molecules of the molded material.
  • the cap 13 When, from the condition shown in FIGS. 1 and 2, the cap 13 is made to pivot around the hinge 14 by actuation in the direction of the arrow f until the container T is closed by cooperation of the stud 22 and the opening 16, the central zone 30 is flexed by 180 ° and this bending causes the deformation, - with stress under partial compression and so by directionally - - partly spherical zones 35 and 36.
  • the plane limiting the free edges of the spherical parts 35 and 36 forms a substantially 90 ° angle with the initial molding plane, so that the hinge means then form a closed structure which contributes to the good overall tightness.
  • the cap 13 When, to gain access to the content of the container T, the cap 13 is removed from the part 10 integral with the container, the compressive stress of the zones 35 and 36 of the spherical part of the hinge 14 is released and their release leads, by elasticity, the desired spring effect for opening the device.
