Definitions

• the present invention relates to a closure device of a container neck and a container equipped with such a device, and a method of manufacturing such a device.
• the invention relates more specifically to the devices including a skirt surrounding the neck of a container, a lower part, when considered that this neck extends vertically with its drinking upwards, is intended to remain around the neck after the first opening of the device, while the rest of the skirt, that is to say its upper part, is provided removable relative to the neck, while being initially connected to the non-removable bottom portion of the skirt by a weakening area to be broken at the first opening of the device.
• This ruptible zone serves as a witness of the first use of the device for the consumer, while the non-removable skirt portion, especially when it has a substantial length, can be used for aesthetic purposes as a dress of the corresponding area of the collar.
• the invention applies in particular, but not exclusively, to the field of packaging wines and strong alcohols in glass bottles whose neck is traditionally dressed with a long skirt with a lower part. removable.
• this part of skirt has a length substantial, that is to say that it extends lengthwise down far beyond the aforementioned bulge of the neck, it is common to provide the retaining projection in the form of a tongue integral with the current part of this skirt part.
• FIG. 7 An example of this type of skirt is schematically represented in FIG. 7, in which the skirt comprises an upper part 101 separated from its lower part 102 by a rupturable weakening line 103 shown solely in dotted lines.
• the lower part 102 is provided with a tongue 104 of the type mentioned above, which projects from the inside face of the part 102 in the direction of the upper part 101.
• the user drives up the upper portion 101, as indicated by the arrow 105, which tends to cause the breaking of the line 103, while the tongue 104 tends to retain the lower portion 102 around a container neck 106, abutting against a transverse shoulder 107 of this neck.
• the retention of the skirt portion 102 is not always effectively provided by the tongue 104 because, due to the constraints that are applied to it, related to the drive 105 of the skirt portion 101, and / or because of the dispersion of the dimensions of the different necks on which the skirt may be placed, the tongue gives way before the complete rupture of the line 103, turning on itself.
• the tongue then moves from its initial shape, represented in solid lines, the section of which is substantially rectangular, to a downwardly curved curved shape, represented in dotted lines, while the skirt portion 102 is driven, together with the portion 101, upwardly relative to the neck 106.
• the tongue offers no vertical resistance with respect to the shoulder 107, so that the latter continues the deformation of the tongue, until it tilts down in a position shown in phantom in Figure 7, the connection zone between the tongue and the skirt portion 102 then forming a kind of non-resistant flexible hinge.
• skirts provided internally with one or more retaining tabs are given in EP-A-0 410 059, US-A-5 129 530 and US-A-5 007 545.

• this segment consists of a base portion, connected to the skirt by a flexible hinge area, and a free end portion, connected to the base portion in an articulated manner, along the line of folding.
• the angular fold line is formed by a suitable conformation of the tongue from a rectilinear configuration of the latter, obtained at the end of molding and similar to the mold exit configuration shown in phantom in FIG. .
• the tabs deform by folding the free end portions towards the base parts, along the angular folding lines defined by the polygonal shape of the sections of these sections. tongues.
• the free end portions of the tongues effectively participate in the retention of the skirt portion intended to remain around the container neck, with the risk that these end portions will yield under the constraints by falling back completely by bending against the base portions, while these base portions generate on the skirt, by leverage around the angular folding lines, essentially radial stresses directed outwards, at the level of the flexible hinge areas (so similar to what is indicated by the arrow 108 in Figure 7).
• the object of the present invention is to provide a tongue-sealing device, of the type described above, which guarantees a resistant and reliable retention of the skirt portion provided with this tongue, without harming the external aesthetics of this part. of skirt.

Indeed, when, during the first opening of the device, the tab abuts axially against the associated bulge of the neck, the biasing force of this tongue is damped by its curved shape and tends to bend the tongue so as to increase the curvature of this form, which further increases the resistance, until breaking of the weakening zone separating the two parts of skirt.

• the curved shape which extends over the entire overhang width of the tongue towards the inside of the skirt so homogeneous, that is to say without area of discontinuity of curvature from its free end to its end connected to the skirt, works in a global bending movement, modifying the overall curvature of the shape.
• the homogeneous dynamic behavior of the tongue does not make it possible to distinguish, according to the overflow width of this tongue, a free end portion and a base portion that have different deformation kinematics different from one of the other.
• This curved shape also has the advantage of transmitting thrust forces to the portion of the skirt above the tongue, this skirt portion may be thicker and stronger than that located below the tongue. In particular, these thrust forces tend to stress the skirt with a moderate radial component, even negligible, which limits the radial deformations towards the outside of the skirt, at the level of the tongue, and thus reduces the risks of whitening of the tongue. plastic material.
