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. The third part of the weakened line extends along the bulge line while being situated on the side of the bulge line turned towards the lid.

Cap for closing the spout of a container

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.

Stopper for a container neck

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.

Method for manufacturing a plug for a container neck

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.

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.

Cap for a container neck

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.

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.

Device for capping a container neck

A cap for a container neck includes a tubular skirt defining a central axis. The skirt includes an internal first skirt part, means for removably fixing the first skirt part to an exterior surface of the container neck, and a second skirt part. The second skirt part includes a first axial end connecting the second skirt part to the first skirt part, internally having at least one surface adapted to abut a free end of the container neck. The second skirt part also includes a second axial end opposite the first end, and an intermediate part extending between the first and second ends. Ribs project radially from the intermediate part in a direction substantially parallel to the axis. A radial dimension of the intermediate part is less than a radial distance between the exterior cylindrical surface of the first skirt part and the interior radial end of the abutment surface.

A stopper device includes a base adapted to be fastened to a neck of a container, and a cap movable relative to the base between closed and open positions. A strand in an unaltered configuration extends along a periphery of the cap. First and second longitudinal ends of the strand are connected to the cap frangibly and non-frangibly, respectively. A hook protrudes toward an outside of the base, and when the strand is in the unaltered configuration, the hook retains a running portion of the strand, blocking movement of the cap from the closed to the open position. The first end of the strand includes a tab for detaching the first end by breaking the frangible connection and moving the running portion toward an outside of the cap until the cap may freely move from the closed to the open position without the running portion being retained by the hook.

Stopper device for the neck of a container

The invention relates to a cap () that comprises a circular skirt (), said cap including an irremovable portion (-) fixedly attached about the neck of a vessel () and a removable portion (-) removably attached to the neck, the irremovable and removable portions being separated by a first weakening line (). In order to maintain the removable portion of the skirt attached to the irremovable portion of the skirt after the first opening, the skirt is provided with a second peripheral weakening line (). It is also provided that the first weakening line extends less than 360&#xb0;, while the two ends (A,B) of the second weakening line are located along the periphery of the skirt respectively between a first (A) of the two ends of a linking portion of the skirt and the hasp (-) closest to said first end, and between the second end (B) of the linking portion and the hasp (-) closest to said second end.

Stopper having a subdivided line of weakness and a method of fabricating such a stopper

The stopper () has a tubular skirt () for fastening it around the container neck, an end wall () perpendicular to the central axis (X-X) of the skirt, and an annular sealing lip () extending into the skirt from the inner face (A) of the end wall. A protrusion () connects the inner face of the end wall to the inner face (B) of a peripheral portion of the lip in order to transmit a movement of the end wall to the lip in the event of excess pressure in the container. In order to release this excess pressure reliably and in a manner which is easy to carry out, the protrusion occupies all the space delimited jointly by the inner face of the end wall, by the inner face of said lip portion and by a geometric plane (P) which passes through said lip portion and intersects the inner face of the end wall along a straight line (L) orthoradial to the axis of the skirt.

Stopper for a container neck and a molding machine for molding a plastics material for the purpose of fabricating such a stopper

This method makes it possible to fabricate a stopper () starting from a tubular skirt () suitable for surrounding a container neck, and provided both with retainer means for retaining it permanently around the neck, and also with fastener means for fastening it removably to the neck. In this method, the skirt and a blade () are moved in rotation relative to each other about the axis (X-X) of the skirt so that the blade cuts a peripheral line of weakness in the skirt, which line of weakness is made up firstly of through notches and secondly, between said notches around the periphery of the skirt, of breakable bridges that interconnect, in the same direction as the axis, a non-removable portion of the skirt, which portion is provided with the retainer means, and a removable portion of the skirt, which portion is provided with the fastener means. With a view to improving the method simply and inexpensively, provision is made for the skirt and the blade to be driven relative to each other through an angular stroke that is strictly greater than 360&#xb0;, while progressively modifying the relative axial position between the skirt and the blade by a movement in axial translation (T). The line of weakness is thus in the shape of a helix having its two peripheral ends defining between them a non-breakable strip that permanently interconnects the removable and the non-removable portions of the skirt.
