Definitions

• the present invention relates to a device for capping a container provided with a neck, this device being of the type comprising:
• a first portion forming a shutter
• a second annular portion intended to be held around the neck
• a third portion which forms a tamper-evident tab associating the first with the second portion, which is connected to these first and second portions by frangible means and which is intended to be removed during a first use in order to release 1 ' shutter.
• the invention also relates to a container provided with a neck on which is mounted a closure device of the aforementioned type. During the very first opening of such a container, the tamper-evident tab is removed by tearing the frangible means, so that the shutter can be moved away from the neck.
• a cap provided for a container.
• This cap includes a annular skirt divided by two lines of least resistance into a retaining ring, a shutter and a tamper-evident tab.
• One of the two lines of least resistance is designed as a closed loop, while the other line of least resistance has an interruption. Therefore, the tamper-evident tab can only be completely detached from the retaining ring, by pulling on an ear provided at one end of this tamper-evident tab.
• this tamper-evident tab has the drawback of being unsightly and the drawback of risking injuring the user and / or hanging objects likely to be unbalanced thereby to fall.
• a completely separable tab closure device does not have such drawbacks, since its tamper-evident tab is intended to be removed from the first and second portions of the device.
• the object of the invention is at least to make the closure devices of the aforementioned type more practical.
• a closure device of this type characterized in that it defines means for storing the tamper-evident tab, once this tamper-evident tab has been separated from the first and second portions.
• the invention also relates to a container provided with a neck, characterized in that it comprises a closure device as defined above, mounted on the neck.
• FIG. 1 is a first perspective view of a closure device according to the invention

• FIG. 6 is a view similar to Figure 3 and shows all of Figures 3 to 5, the tamper evident tab is stored after being removed;
• FIG. 7 is a view similar to Figure 3 and shows a sealing device according to a first embodiment of the invention

• Figure 10 is a partial perspective view, with parts broken away, of a container according to a second alternative embodiment of the invention.
• a closure device 1 is shown either alone, or mounted on the neck 2 of a container, which is a bottle 3 partially shown. More specifically, in Figures 1 to 3, the closure device 1, produced by molding of plastic material, is still intact or virgin. It is then in one piece and, for the most part, symmetrical about an axis XX '. It has three portions, one of which forms a shutter 4, and another of which is an annular skirt 5 for mounting the device 1 on the neck 2. The last portion, which extends between the other two, around the axis X -X ', is a tamper-evident tab 6 which, until it is removed from the device 1, associates the shutter 4 with the skirt 5.
• One of the two ends of the tamper-evident tab 6 is provided with a gripping member 7.
• Frangible means intended to be torn during the withdrawal of the tamper-evident tab 6, comprise two continuous lines of lower mechanical resistance 8 and 9, each resulting from the presence of a groove on the external face of the closure device 1.
• the line of least mechanical resistance 8 extends between the tamper-evident tab 6 and the shutter 4.
• the line of least mechanical resistance 9 extends between the tamper-evident tab 6 and the skirt 5.
• a hinge joint 10 with a pivot axis
• AA ' is provided between the two ends of the tamper-evident tab 6 and comprises two elastic strips 11 which connect the shutter 4 to the skirt 5 and are angularly offset around the axis XX' from one another .
• the line of least mechanical resistance 9 inclines towards the free edge 12 of the skirt 5, then defines a hoop 13, the concavity of which faces the shutter 4 and which s extends diametrically opposite the joint 10.
• closure device 1 is mounted on the neck 2.
• the skirt 5 is then retained around this neck 2 by snap-fastening means consisting of two complementary annular beads, one of which is referenced 15 and provided inside the skirt 5, and the other of which is referenced 16 and provided outside the neck 2.
• the neck 2 has a helical and external thread 17, by means of which a cap (not shown) can be screwed onto this neck 2, in the absence of the plugging device 1.
• This thread 17 is axially offset towards the free edge of this neck 2, with respect to the bead 16.
• the skirt 5 and the neck 2 define between them an annular storage space 18, to which the hole 14 gives access.
• the tamper-evident tab 6 opposes the withdrawal of the shutter 4, which seals the passage delimited by the neck 2.
• the tamper-evident tab 6, grasped by the gripping member 7, is completely removed by tearing the lines of least resistance 8 and 9, which releases the shutter 4, which can then be tilted around the axis AA 'of the articulation 10, away from the neck 2, in the position illustrated in FIG. 6.
• the user is then not embarrassed by the tamper-evident tab 6 removed, since he can slide it into the storage space 18, through the hole 14.
• he begins by inserting the end of this tamper-evident tab 6 opposite the gripping member 7 in the hole 14, then in space. 18. Then, it gradually penetrates the tamper-evident tab 6 into the storage space 18, by exerting a thrust symbolized by the arrow F in FIG. 4.
• the frangible means are formed by two continuous lines of lesser mechanical resistance, the lateral edges of the tamper-evident tab 6 are substantially regular, so that this tamper-evident tab passes through the hole 14 without catching.
• the tamper-evident tab 6 can be pushed in this way until the gripping member 7 abuts against the edge of the hole 14 and locks at the entrance to the storage space 18.
• the tamper-evident tab 6 is is then in the position illustrated in Figures 5 and 6: it is mounted, or if one prefers stored, in the storage space 18 and only its gripping member 7 protrudes outside. However, since it is hidden by the open shutter 4, as can be seen in FIG. 6, this gripping member 7 does not cause any discomfort when the content of the bottle 3 is poured into another container or when a user drinks from the neck by placing its mouth opposite the hinge 10.
• the hole 14 facilitates rapid drainage of a liquid that can be trapped between the neck 2 and the skirt 5 during assembly of the closure device 1, and / or it promotes and accelerates the evaporation of this liquid which may be a residue of a foodstuff poured into the bottle 3 or of cleaning water.
• a closure device 101 according to a first alternative embodiment of the invention is shown in Figures 7 to 9. In Figures 8 and 9, it is mounted on the neck 102 of a bottle 103 according to this first alternative embodiment of the 'invention.
• the references designating parts of this closure device 101 or this bottle 103 will be constructed by increasing by 100 the references designating the similar parts on the device 1 or the bottle 3.

• the storage space 118 is axially offset and extends between the inner bead 115 of the skirt 105 and the free edge 112 of this skirt 105, as can be seen in FIG. 8.
• the passage formed through the wall of the skirt 105, to give access to the storage space 118 is not formed by a hole, but by a notch 114, delimited from the free edge 112 and elongated in the direction of the shutter 104.
• the tamper-evident tab 106 is stored inside the storage space 118.
• a bottle 203 according to a second variant embodiment of the invention is shown in FIG. 10.
• the neck 202 of the bottle 203 is devoid of the thread 17 of the bottle 3.
