Definitions

  • the present invention relates to a plastic screw cap.
  • the object of the invention is to provide a stopper intended for example for corking bottles made of hard synthetic material, such as polyvinyl chloride, and to provide excellent protection for the conditioned liquid, mineral water or other products, by using a material which ensures good impermeability to air and in particular to oxygen vis-à-vis which the mineral salts are very sensitive.
  • the plug it relates to comprises on the one hand a plug body made of an air-impermeable material from the bottom of which protrudes a part in the form of an annular chimney comprising near its free end a peripheral ring continuous or discontinuous, facing outwards, and on the other hand a shutter which, intended to be mounted inside the body of the stopper, and made of a more flexible material than this, has a general shape of a bowl , whose skirt has a diameter between the outside diameter of the chimney and the inside diameter of the neck of the corking bottle, and a height at least equal to that of the chimney projecting from the bottom of the stopper, a discontinuous peripheral ring on continuous projecting from the internal face of the skirt, which is arranged so that in the engaged position of the bowl on the chimney, the shutter ring is located between the chimney ring and the bottom of the plug, the inside diameter of the shutter ring being less than the outside diameter of the plug ring.
  • the two elements being produced independently of one another can be assembled at the end of manufacture, the shutter remaining retained by clipping inside the stopper during the various manipulations prior to the capping operation.
  • the shutter remains perfectly integral with the body of the cap, thanks to the mutual supports of the rods of the body of the cap and of the shutter.
  • the cap body is made of polypropylene, while the shutter is made of polyethylene.
  • the body of the stopper fulfills the function of attachment to the neck of the bottle, and forms an air barrier, while the shutter, given its flexibility, ensures the sealing of the stopper.
  • this sealing is favored by the fact that the shutter, made of a flexible material, is pinched between two rigid parts constituted respectively by the chimney of the body of the stopper and by the neck of the bottle.
  • the bearing zone of the shutter skirt on the inner face of the neck of the bottle is disposed above the rods respectively of the chimney of the body of the stopper and of the skirt of the shutter.
  • the upper edge of the shutter skirt does not have an outward return covering the neck of the bottle.
  • Another object sought by the invention is to provide an opening with separation of the tamper-evident ring by simply unscrewing the cap without having to tear a tab, with as obvious evidence as possible of the non-violation of the closure. It is thus important that after the first opening of the cap, the tamper-evident ring detaches very substantially therefrom in order to allow immediate viewing of the first opening even after replacing the cap.
  • this cap of the type fitted with a tamper-evident ring comprising profiled notches intended to cooperate with profiled notches of the neck of the container, to allow rotation of the ring in the direction of screwing on the cap and to prevent its rotation in the direction of unscrewing of the cap, and in which the ring is connected to the body of the stopper by sectionable bridges, is characterized in that the ring comprises at least one axial slot delimiting two sections connected to each other at the level of the slot by a tab of small cross section relative to the height of the Ring.
  • the slots made in the tamper-evident ring are two in number and are arranged diametrically opposite.
  • the stopper shown in the drawing and designated by the general reference 2 comprises a stopper body 3 made of polypropylene and a shutter 4 made of polyethylene.
  • the plug body 3 has a traditional structure, that is to say has a substantially cylindrical skirt, provided with an internal thread 6, closed by a bottom 7, and the free end of which is fitted with a ring d inviolability 8, which is connected to it by bridges 9.
  • annular chimney 10 comprising on its outer face and near its free end, a peripheral ring 12 which, in the embodiment shown in the drawing, is discontinuous.
  • the shutter 4 comprises for its part a cylindrical skirt 13 of height at least equal to the height of the chimney 10, one of the ends of which is closed off by a bottom 14 and the other end of which is intended to be pressed against the bottom 7 of the body 3 of the plug.
  • the skirt 13 of the shutter 4 with a diameter between the outside diameter of the chimney 10 and the inside diameter of the part 15 of the neck 16 of the bottle at which the seal is to be made, comprises for its part a rod 17 projecting from its internal face. As shown in Figure 2, the rod 17 is arranged so that after mounting the shutter in the body of the plug the rod 17 of the shutter is sited between the rod 12 of the chimney and the bottom of the plug.
  • the contact between the rods 12 respectively of the chimney 10 and 17 of the obturator 4 ensures the clipping of the obturator in the body of the stopper allowing on the one hand a simultaneous manipulation of these two elements before capping and on the other hand the simultaneous removal of these two elements during the operation of opening the bottle.
  • the liquid tightness is ensured under excellent conditions, taking into account the pinching of the shutter skirt, made of a relatively flexible material, between the chimney 10 of the stopper and the neck 15 of the container, which for their part are made of a harder material.
  • the tamper-evident ring has two diametrically opposite slots 18, extending over its entire height with the exception of a tab 19 of low height with respect to the ring height.
  • the profiled notches 20 of the ring passing over the profiled notches 22 of the neck 16 of the container cause an increase in the diameter of the ring by irreversible elongation of the lugs 19.
  • the cap is unscrewed and after breaking of the bridges 9, the ring is released, and can slide freely along the neck of the container, given the increase in its diameter due to the lengthening of the legs 19. This allows to immediately see if a bottle has been or not opened.
  • the invention brings a great improvement to the existing technique, by providing a plug of simple design and structure, ensuring excellent sealing qualities, achieving good liquid tightness and good air impermeability.
  • the structure of this stopper makes it possible to immediately view the first opening of the container with which it is fitted.
  • the invention is not limited to the sole embodiment of this stopper described above by way of example; on the contrary, it embraces all of its variant embodiments.
  • the body of the plug and the shutter could be made of materials different from those mentioned in the description, that the bowl of the shutter could present a return towards the outside coming to cover the upper edge. of the bottle or that the number of connecting tabs between the different sections of the tamper-evident ring could be different without departing from the scope of the invention.
