Definitions

  • the present invention relates to a plug without added seal used to close and seal the opening of the neck of a container, such as a bottle of liquid.
  • plug without added seal is meant a plug which makes it possible to seal the opening of the neck of a container, in particular of liquid, without necessarily needing a seal usually consisting of a disc of foam placed under the lid of the cap, or alternatively an injected or molded bead acting as an O-ring.
  • the existing plugs may be provided with a groove disposed below the seal where the seal is housed. The pressure exerted by the tension ring or the attachment system during the mounting of the cap compresses the seal on the upper surface of the opening of the neck and thus ensures the desired seal.
  • the present invention relates to a cap which provides excellent sealing without having such a reported seal.
  • plugs which do not require an insertseal provided that they are provided with circular lips, teeth and / or protuberances which are located under the cover axially at the neck of the plug or on the peripheral skirt of the plug. it in order to come to bear on the neck and thus get the desired seal.
  • the plugs in question are of course intended to hang on even withdrawals specifically provided for this purpose in the outer portion of the neck.
  • handling storage or delivery causes a movement of water or any other liquid stored in the cylinder, which can create a real effect surf.
  • the bottle once placed on the fountain usually in the inverted position, creates a pressure exerted on the cap because the liquid that flows is replaced by air whose pressure ensures a transfer by gravity .
  • the action of the atmosphere also exerts a variable external pressure according to the meteorological conditions (temperature, pressure). It is the difficult balancing between internal pressure and external pressure that must subtract the cap from the risk of leakage.
  • the present invention relates to a plug without attached insert that meets all the needs mentioned above in terms of impermeability, sealing and hermetic effect.
  • US 4,461,392 which relates to a plastic bottle screw cap according to the preamble of claim 1, having a main annular sealing flange extending from the top wall of the plug to engage the upper wall surface of the neck from the bottle.
  • the main flange is flexible and wide enough to cover a major portion of the upper wall surface to accommodate the irregularities of that surface.
  • the plug further has a secondary annular sealing flange extending radially downward from the top wall of the plug to engage the outer side wall of the bottle neck.
  • CA 1 196 606 which relates to a plastic plug having a circular sealing lip which is disposed in the junction area between the wall portion of the plug and the plug end portion, and extends inwardly at an inclined angle. At its smallest diameter, the sealing lip has a rounded sealing portion. Below the sealing portion, the sealing lip is enlarged outward in a funnel configuration to receive the neck of a container. According to this arrangement, a reliable leakage measurement is obtained at the outer wall portion of the container neck, even when there are wide variations in tolerances. In each case, the sealing zone which extends circumferentially around the neck of the container is of linear configuration, which improves the sealing effect of the sealing lip.
  • the plug according to the present invention is however distinguished from existing plugs in that its second lip is also projecting under the closure cap around the first lip, and is further provided with several teeth or protuberances positioned to form several points contact with the neck when the second lip is in the folded position and thus form several sealing barriers with a staircase effect.
  • the teeth or protuberances thus marry the shape of the neck and absorbs the defects and surface scratches due to manufacturing imperfections or handling accidents.
  • the first and second lips are joined by a thicker zone to enhance their stiffness and thus make them less flexible, which causes them to bend with more pressure on the neck and provide a suction cutting effect.
  • the lid has a lower surface provided with a circular depression forming a groove adjacent to the first lip.
  • This groove also gives a space for folding in the first lip, which thus ensures easier backflow in case of surf and therefore better efficiency and sealing.
  • the peripheral skirt has an internal upper portion provided with a groove forming, by its position, a third outer lip to the other two, this third lip applies a pressure on the cap when it is attached to the neck and thus ensures a better tightening of the tension ring of the stopper against the bead of the neck, with further maximum compression of the first and second lips in the folded position and an additional point of contact with the neck.
  • the skirt of the cap according to the invention is advantageously provided with a pull tab associated with a thin tear to facilitate its removal.
  • the cap is also advantageously injected in one piece of plastic material.
  • the plug 1 without attached, the preferred embodiment of the invention illustrated in the accompanying drawings, is intended to close the opening of the neck 2 of a container such as for example, a water bottle usable in reverse position in a fountain of distribution.
  • the stopper 1 comprises a closure cap 3 around which a skirt 5 sized to fit around the neck 2 projects.
  • the skirt 5 has an internal surface provided with attachment means to the illustrated neck, which in the embodiment consists of a tension ring 7 positioned to be able to engage under a bead 9 formed in the same neck so as to ensure the fixing of the cap on the neck.
  • the manner in which the tensioning ring 7 is placed under the bead 9 of the neck so as to hold the cap in the closed position is illustrated more precisely on FIG. figure 4 .
  • the stopper 1 also comprises a first circular lip 11 which is projecting under the closing cap 3 near the opening of the neck.
  • This first lip is in practice folded against the neck towards the opening thereof when the cap is fixed, as is illustrated here again on the figure 4 . In this folded position, the first lip 11 prevents any effect of surf when the container is moved.
  • the cap also includes a second circular lip 13 which is external to the first and positioned to be also folded against the neck in a direction opposite to that of the first lip when the cap is attached.
  • the folded position of the second lip, once the cap is installed, is again clearly illustrated on the figure 4 .
  • the second lip 13 is itself projecting directly under the closing cap 3 around the first lip and is further provided with a plurality of teeth or protuberances 15 positioned to form a plurality of contact points with the surface of the neck 9 when the second lip 13 is in the folded position.
  • This makes it possible to form several sealing barriers with a staircase effect.
  • the teeth or protuberances conforming to the shape of the neck absorb defects and / or surface scratches due to manufacturing imperfections or handling accidents.
  • the first and second lips 11 and 13 can be joined by a thicker zone, which makes it possible to reinforce their rigidity and thus make them less flexible. This causes them to bend with more pressure, retain a spring effect on the neck and ensure a suction cutting effect.
  • the cover has a lower surface provided with a circular depression 19 forming a groove adjacent to the first lip 11.
  • This groove in practice gives a space for folding to the first lip and ensures thus easier backflow in case of surf and therefore a better seal.
  • the particular position and the advantage that the presence of this circular depression 19 may have in use are here even more clearly illustrated on the figure 4 .
  • the peripheral skirt 5 has an inner upper portion provided with a groove 21 forming, by its position, a third lip 23 external to the other two, which creates a radial tension and applies a pressure on the plug when the one it is attached to the neck and which therefore ensures a better tightening of the tension ring 7 against the bead 9 of the neck 2, with further compression of the first and second lips 11 and 13 in the folded position.
  • the third lip 23 also provides an additional point of contact with the neck.
  • the skirt may advantageously be provided with a pull tab 25 associated with a thin tear 27 to facilitate the removal of the plug from the neck.
  • the plug according to the invention is preferably injected in one piece of plastic material.
  • the plug according to the invention therefore has the advantage of being perfectly hermetic.
  • the first lip 11 has the advantage of containing the water hammer surf caused by the movement of the liquid in the neck. Because of the profile of the throat, it allows the liquid to reflux.
  • the third lip 23 also has the advantage of possibly correcting the difference specific to each model of bottle and thus ensure a perfect tension of the ring 7.
  • the third lip 23 by positioning forces more closely the tension exerted on the operculum and therefore, plate even better the first and second lips 11 and 13 on the top of the neck.
