Abstract: A cap for closing a neck of a bottle is disclosed. The cap includes a lid for closing off the neck and a skirt for fixing to the neck. The skirt is provided with a bulge line for interfering by wedging with the neck, a weakened line to be ruptured by propagation of a tear, and a stop means for preventing the tearing propagating in the rectilinear extension of a first part of the weakened line that runs along the bulge line while being situated on the side of the latter opposite to the lid. The weakened line also includes second and third substantially rectilinear parts which, on the periphery of a skirt, follow on respectively from the first part to the second part of the weakened line. The second part of the weakened line avoids the stop means and extends on either side of the bulge line, while being inclined both with respect to the bulge line and with respect to the direction of the axis of the skirt.

Abstract: The invention relates to a sealing device which includes a tubular skirt, suitable for being removably attached to a neck of a container in order to seal said neck, and an annular lip, arranged inside the skirt, and suitable for resting sealingly against an inner surface of the neck when the skirt is attached to the neck.

Abstract: A stopper for a container neck, comprising: a skirt having a generally tubular shape and being centered on an axis, the skirt being adapted to surround a neck of a container, and being provided internally with a snap-on member adapted to fasten the skirt to the neck in a removable manner by jamming the snap-on member with an external projecting boss of the neck of the container; and an opening strip having a generally annular shape and including a peripheral portion that is permanently connected to a peripheral portion of the skirt, the strip being movable relative to the skirt between: a first position, in which the strip surrounds an external lateral surface of the skirt, by providing an annular space radially between the external lateral surface of the skirt and an inner surface of the strip; and a second position, in which the inside of the strip is substantially detached from the skirt in order to enable the strip to be manually grasped so that the skirt is unsnapped from the neck.

Abstract: The present disclosure relates to a manufacturing method for a plug for a container neck. In one implementation, a skirt of the plug is molded and provided with an attachment device adapted to removably attach to the container neck and with a permanent retention strip around the container neck. The retention strip is adapted to pass, by folding, from a molding configuration to an operating configuration. A peripheral break line is then cut out in the skirt, adapted so as to be broken during the first opening of the plug. In some implementations, the retention strip may be prefolded and thereby pass from a molding configuration to an intermediate prefolded configuration. The retention strip is then folded until it passes into an operating configuration. In some implementations, the folding of the retention strip may pass the retention strip from an intermediate prefolded configuration to an operating configuration.

Abstract: The invention relates to a stopper device with an external cap made from plastic and an internal insert for fixing the device around the neck of the container. The sleeve of the cap forms a head, into which the insert may be introduced and permanently fixed and a skirt extending axially from the insert. According to the invention, contamination on the neck of the container may be limited and the appearance improved. Particularly at the base of the neck, the skirt essentially forms a frustum converging towards the axis of the sleeve on extending from the head, before the installation of the device around the neck, the frustum forming, at the end opposite the head, an internal surface to come into contact against the container neck under the influence of an elastic deformation of the sleeve as a result of the installation of the device around the neck.

Abstract: A cap for sealing a container neck includes a first skirt section, and a second skirt section. The second skirt section includes a first axial end connected to the first skirt section, a second axial end opposite the first axial end and connected to an end wall of the cap, and an intermediate section extending axially between the first and second axial ends. The cap further includes a plurality of ribs distributed around the central axis and projecting in a radial direction from at least the intermediate section towards the central axis. Each rib includes an exterior radial end connected to an interior cylindrical surface of the intermediate section, and an interior radial end radially opposite the exterior radial end. The interior radial end has at least one protrusion projecting in a direction orthogonal to the radial direction.

Abstract: A packaging assembly includes a bottle, which may be used upside-down such that a neck is turned towards the ground, and a closure without any added seal gasket for closing the neck. This closure includes a cap for obturating the neck, and a skirt for attachment to the neck. The cap includes an inner sealing lip, delimiting on its outer face, a convex tight bearing surface for bearing tightly against the inner face of the neck, and a substantially flat ramp surface, which connects the tight bearing surface to a lower axial end of the lip, and which, while the lip is deformed with the remainder of the closure when an inner clip of the skirt interferes with an outer bead of the neck during placement of the closure on the neck, may interfere with a free end of the neck to guide engagement of the lip inside the neck.

Abstract: A capping device includes an external outer cap adapted to be removably fixed to the exterior face of a container neck, and an internal insert adapted to plug the opening of the neck. The insert is adapted to be fitted to the neck independently of the outer cap and before fitting the outer cap to the neck. When it is fitted to the neck, the outer cap is adapted to be permanently fastened to the insert. When filling the container, the insert may include means for retaining it on the neck adapted to connect the insert mechanically to the neck before the outer cap is fitted to the neck, thereby sealing at least the exterior peripheral surface of the free end of the neck against a cleaning liquid applied externally to the neck.
