Abstract: A molding apparatus for molding a closure device for a container. The closure device may be tethered to the container, and may open and close via a hinged articulation. The closure device includes a cylindrical body comprising hinge-connecting areas with pockets formed in the interior wall and defining an inner surface of the hinge-connecting areas, and hinges extending downwardly from the hinge-connecting areas and positioned at or below a bottom edge of the cylindrical body. The molding apparatus comprises a cavity insert component and a core component that cooperate to form mold surfaces to mold the closure device such that hinges are located below the cap area of the closure device, and hinge-connecting areas formed by projections in the core mold component and recesses in the cavity mold component are located within the cap area are flanked by membranous areas.

Abstract: A closure for sealingly closing a container neck having a tubular body with a top wall, an annular side wall, an intermediate wall joining the side wall to the top wall and an annular tamper evidence band frangibly connected to an open end described by the side wall. The band includes retaining cams protruding from its inner surface. Each cam has a lead-in ramp for engaging, in use, the flange of a container neck as the neck is introduced into the open end of the body and a stop for engaging the flange to separate the band from the body when the closure is subsequently removed from the neck. Each lead-in ramp has a central recess therein.

Abstract: A closure device for a container that defines a neck and an annular flange. The closure device comprises a cap body, a tamper evidence (TE) band positioned below the annular flange, a tongue that extends from the cap body towards the tamper evidence band and first and second leashes positioned on either side of the tongue. The first and second leashes connect the cap body to the tamper evidence (TE) band, and allow the cap body to be removed from the neck of the container while remaining attached to the tamper evidence (TE) band. When the cap body is actuated to a fully open position the first and second leashes act as a torsion spring for causing the tongue to exert a force against the neck of the container for retaining the cap body in the fully open position.

Abstract: A closure device for a container having a neck including an annular flange, the closure device comprising: a cap body; a tamper evident (TE) band positioned below the annular flange when assembled in the container; a first hinge and a second hinge defined on the cap body; a leash connected to the TE band, the first hinge and the second hinge; the leash allowing for the cap body to be separated from the TE band during opening, but to remain connected thereto via the leash; a tongue protruding from the cap body between the first and second hinges; when the cap body is actuated from a closed configuration relative to the neck to a fully open position: the leash is configured to retain the cap body to the TE band; an interaction of the tongue and the neck is configured to retain the cap body in the fully open position.

Abstract: A closure (1) for sealingly closing a container neck (11) having a tubular body (2) with a top wall (4), an annular side wall (5), an intermediate wall (6) joining the side wall (5) to the top wall (4) and an annular tamper evidence band (3) frangibly connected to an open end (21) described by the side wall (5). The band (3) includes retaining cams (31) protruding from its inner surface (30). Each cam (31) has a lead-in ramp (32) for engaging, in use, the flange (12) of a container neck (11) as the neck (11) is introduced into the open end (21) of the body (2) and a stop (33) for engaging the flange (12) to separate the band (3) from the body (2) when the closure (1) is subsequently removed from the neck (11). Each lead-in ramp (32) has a central recess (34) therein.

Abstract: A gas spring has a closed cylinder, the interior of which is divided into a first working space and a second working space by a piston, which is free to slide back and forth in the cylinder. The piston has a piston rod, which extends through the second working space and out from the cylinder through a seal. The first working space and the second working space are filled with pressurized gas. A compensating space, which is filled with a compensating medium, is also provided. The volume of this compensating medium changes with the temperature, and this change in volume brings about a corresponding change in the volume of the first working space. The compensating medium is an incompressible medium which expands in volume as the temperature drops, this expansion leading to a decrease in the volume of the first working space.
