A seal for a closure assembly that includes a seal ring; and a carrier being coupled to the seal ring, extending circumferentially and radially outwardly of the seal ring to a radially outer periphery, and having a circumferentially extending pocket in the radially outer periphery adapted to release a vacuum pressure.

A parenteral vial, stopper and cap assembly comprises a vial having a body defining an interior, and an opening leading to the interior. The assembly further comprises a stopper configured to sealingly engage the opening, a cap configured to cover the opening and the stopper. The stopper and the cap fit together to form an integral unit configured to cap the vial. The cap moves with respect to the vial between a partially engaged position that permits gas flow out from the vial interior, and a fully engaged position in which the stopper sealingly engages the opening.

A stopper has a head part and a stopper part. The stopper part extends from the head part to a lower end and has flanges, between the head part and the lower end, that have different diameters that increase from the head part to the lower end of the stopper part. A container has a mouth and neck and shoulder inner surfaces. The stopper part is inserted into the container through the mouth, the head part remains outside the mouth, at least one of the flanges proximate neck sealingly engages the neck inner surface, and at least one of the flanges proximate to the shoulder sealing engages the shoulder inner surface. A fluid tube is retained by the stopper. The fluid tube extends from an inlet within the container outwardly through the mouth to an outlet outside the container.

A closure includes an overcap having an annular skirt, and an annular wall extending inwardly from the skirt. A lid is carried by the overcap radially within the annular skirt, and includes a hub, and an annular margin extending radially outwardly with respect to the hub, and having upper and lower surfaces. An annular container seal extends circumferentially continuously around the annular margin. One or more vents may extend through the annular margin between the upper and lower surfaces thereof at one or more discrete circumferential locations radially inward with respect to the container seal. One or more vent seals may be disposed at the one or more vents between the lid and the overcap.

A plastic injection moulded wide mouth container body and container cover locking and sealing mechanism which includes an annular flange and an annular angular notch groove respectively in a pre-determined configuration so as to provide a tight leak-proof seal when the container lid is fitted over, around and within the container body hoop annular fin and upon locking engagement. The present invention incorporates a multi-use plastic handle grip which may also be used as a closure opening levering tool to disengage the container lid from the container body in a safe and ergonomic manner. More significantly the invention, and when in use and upon first usage opening, does not require the removal of any portion of the container lid to comply with tamper evident requirements, nor needs other tools such as knives and metal levers to completely remove the container closure from the container body. Still furthermore the invention includes a plurality of venting channels and adjacent ports which allows the evacuation of increased internal air pressure within the closed container head space with no leakage of the packaged fluid product. The invention may be adapted to plastic containers of any size and shape being round, oval, square or rectangular tapered or straight wall containers.

A closure for a container. The closure comprises an end panel, a sidewall depending from the end panel and having an inwardly directed curl, and a sealing compound extending down the inner surface of the sidewall. A plurality of ribs are formed in the sealing compound, spaced apart around the circumference of the sidewall, each rib extending down the sidewall and projecting radially inwardly.

A container closure device (20) for a container (10), in particular for a beverage can (10), comprises a lid (30) having an upper face (31), a lower face (32), and an opening (33). The container closure device (20) further comprises a closure (50) having a closure part (51) for opening and closing the opening (33) and an operating device (40) for actuating the closure part (51). The closure part (51) is arranged on the lower face (32) so as to be pivotable about a first axis (A) which extends substantially parallel to the lower face (32). The operating device (40) is arranged on the closure part (51) so as to be rotatable about a second axis (B) and be rotatable from a first position (S.sub.1) into a second position (S.sub.2). The opening (33) can be closed by rotating the operating device (40) into the first position (S.sub.1) and can be opened by rotating the operating device (40) into the second position (S.sub.2).

a vacuum container and a system which includes a complementary base, including a three-part airway, a sealing lid, and a lid release button. The three-part airway features an internal air chamber, an extraction airway, and a one-way check-valve preventing ambient air from penetrating the internal air chamber through the extraction airway when vacuum sealed. The extraction airway extends between the top and the bottom of the container and includes an internal air extraction outlet, disposed at the top of and within the internal air chamber, and an external air extraction outlet outside the container, disposed at the bottom of the container, and configured to be coupled to an external air pump. A complementary method is also provided.

The present teachings relate to a screw-cap closure, in particularly the closure shell, which consists of horizontal and vertical elements, placed on the closure shell's cylindrical sidewall inner surface. Horizontal parts include a plurality of thread segments, and both ends of the cylindrical sidewall (where cylindrical side wall ends and slopes start). Vertical elements consist of areas with increased wall thickness under both ends of the plurality of thread segments. Combination of aforementioned elements create a frame, that guarantees sufficient structural stiffness and allows to decrease the closure's wall thickness.

A pressurized closure assembly is provided which has a connector assembly to allow improved application of torque in limited space conditions to rotate a head away from the hub of the closure assembly.
