Abstract: The present invention relates to a tethered screw plastic stopper, comprising a tamper shell positioned around the stopper. The tamper shell includes a retaining feature operable to cooperate with a top ring extending outwardly around a bottle neck. The stopper also includes a roof connected to the tamper shell through a hinge and separably connected to the tamper shell through a weakness line, wherein the tamper shell may be moved downwardly in rotation into an opened position.

Abstract: The present invention discloses a tethered stopper affixed to a bottle neck finish. The stopper includes a closure shell, a tamper band, and a strip connecting the closure shell to the tamper band at the perimeter of both the closure shell and the tamper band. The bottle neck finish includes a transport ring having a retaining feature configured to receive and retain the strip of the stopper when the closure shell is removed from the bottle neck finish. Also discloses is a method for securing the tethered stopper within the tamper band.

Abstract: The present invention relates to tethered plastic stopper having a closure shell, a tamper band, and an annular ring. The annular ring is formed between a bottom weakness line separably linked through bottom bridges to the top edge of the tamper band and to the bottom edge of the annular ring and a top weakness line separably linked through top bridges to the top edge of the annular ring and to the bottom edge of the closure shell. At least one of the bottom bridges is configured to prevent disconnection of the annular ring from the tamper band and at least one of the top bridges is configured to prevent disconnection of the annular ring from the closure shell. The remaining bottom bridge and the remaining top bridge having a section exceeding at least 30% relative to the section of the bottom bridges and top bridges, respectively.

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: 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: 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.
