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.
• 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.
• the sealless plug according to the invention for closing a neck opening of a container comprises, as basic elements:
• a second outer circular lip 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 fixed.
• 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 reinforce their rigidity and thus make them less flexible, which causes them to bend with more pressure on the neck and ensure an effect. suction cup.
• the cap 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 inner 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 furthermore 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.
• Figure 1 is a perspective view from below of a plug without reported seal according to a preferred embodiment of the invention
• Figure 2 is a partial sectional view of the cap shown in Figure 1 when it is placed for installation on the neck of a container;
• Figure 3 is a view similar to Figure 2, showing the plug when the latter is partially depressed.
• Figure 4 is a view similar to Figures 2 and 3, showing the cap when it is fully installed on the neck of the container.
• 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 3 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 tension 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 in FIG. 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 in FIG. 4. In this folded position, the first lip 11 makes it possible to avoid any surfing effect 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 in FIG. 4.
• the present invention is mainly characterized in that 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 several points of contact 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 are 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 preferably 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 fold space to the first lip and thus ensures easier backflow in case of surf and therefore a better seal.
• the particular position and the advantage that can have the presence of this circular depression 19 in use are here even more clearly illustrated in FIG. 4.
• the peripheral skirt 5 has an internal 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 cap when 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 3, with further compression of the first and second lips 11 and 13 in position folded.
• 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 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.
