Abstract: A stopping device, comprising a stopper and a plastic cap to cover a container's neck with the stopper in the neck, the cap comprising a cover and a ring surrounding the stopper and the neck when mounted onto the neck, the ring and cover being produced as a single component connected by at least one part breakable by a force parallel to a central axis of the ring directed towards the stopper, the cover having an element resting against the stopper, the breakable part having bridges extending between an outer radial edge of the cover and an inner radial edge of the ring, and a channel in an arc of a circle defined between two adjacent bridges, the length of the cover's outer radial edge and the length of the rings inner radial edge, the channel having radial width smaller than 0.3 mm and axial height more than 0.15 mm.

Abstract: A device connecting a recipient closed by a perforatable stopper and a container for a needle, comprising a base for mounting the container, the base defining a central bore and comprising means for mounting on the recipient, the needle pertaining to a subset engaged in the central bore forming part of the device, for mounting on the container, and being arranged in the central bore parallel to the bore's longitudinal axis, and a sealing sleeve arranged in the central bore, around the needle and in contact therewith, the base being a single component and comprising a body for perforating the stopper extending from an intermediate wall of the base, away from the central bore and parallel to its central axis, up to a distal end, the perforating body being hollow and the inner space thereof communicating with the central bore and with a space radially surrounding its distal end.

Abstract: The closure device (500) comprises a stopper (501) made of elastomer and a cover (502) suitable for covering both the neck (12) of a container and stopper (501) in place in said neck (12). The cover (502) is made of plastics material and comprises a ring (503) and a drive member (504). The ring (503) may surround the stopper (501) and the neck (12) in the mounted configuration, the ring being provided with locking means (503G) for locking on the neck (12). The drive member (504) may be mounted on the ring (503) in arbitrary angular orientation about a central axis (X503) of the ring. The drive member is provided with an annular edge (505D) suitable for being engaged between an outer skirt (503A) of the ring (503) and at least one tab (503G) forming locking means and extending radially towards the central axis (X503) of the ring from the skirt (503A).

Abstract: This device comprises an elastomer stopper (501) and a cap (502) suitable for covering both the neck (12) of a container and the stopper in position in this neck. The cap comprises a ring (503) provided with means (503G) for locking it to the neck and an operating member (504). The operating member (504) is fitted with at least one deformable part (506C) for transmitting a thrust load (f2) parallel to a central axis (X503) of the ring (503), between two portions (505, 506) of this member (504) or between an external material (301) and this member (504). The load transmitting part (506C) is deformable between a first configuration in which its length (L506) parallel to the central axis (X503) is a first value and a second configuration in which this parallel length is a second value that is less than the first value.
