A bung closure for gas-tight and liquid-tight closure of a bung opening of a container, includes a cup-shaped basic body made from metal and having a disk-shaped base and an adjoining, upwardly open, tubular ring part; at least one interlocking element in the form of a shaped sheet-metal strip or a tab provided within the cup-shaped basic body for engagement with a screwing tool for screwing the bung closure into, and out of the bung opening of the container; and a stable plastics layer provided on the outer side of the ring part, with an external thread formed on an outside of the plastics layer for threaded engagement with the internal thread of the bung opening.

An anti-tamper synthetic elastomeric cap structure, of the type having a dilated external head in abutment with an apex to form a “T-cap”, includes a composite structure having, embedded in the head, an endoskeleton with external appendages that provides a cage having a circumferential projection, with respect to a penetrating body under the head that defines a band having a notching therein and disposed about the neck of a bottle to provide a pre-fracture line and a grasping appendage.

Aspects and techniques of the present disclosure relate to an internal cover/vent handle arrangement, in association with a container, such as a 5 gallon bucket with a slanted sidewall for evacuating air volume above stored material. The disclosure relates to a squeeze-actuated vent valve arrangement arranged and configured to be easily operated even while deeply recessed in the bucket. The disclosure also relates to a deflectable outer seal arrangement configured to seal against a slanted sidewall of a bucket.

A stopper for a container with a lid with a peripheral wall engaging around the neck of the container and with an olive seal provided with an outer, peripheral annular bead for jamming engagement in the container opening includes an inner surface of the olive seal having a ribbed wall surface, which is defined by a plurality of grooves and webs extending in the longitudinal direction on the wall of the olive seal.

The present invention discloses a one-button-opened cup cap and cup. The cup comprises a cup body and a cup cap partially inserted into the cup body. The cup cap comprises a pressing assembly, a water shutoff assembly and an exhaust assembly. The water shutoff assembly comprises a main cap, a sealing cap and a linkage component. The pressing assembly is connected with the main cap. The linkage component is provided with an air outlet hole plugged by the exhaust assembly. The pressing assembly is longitudinally pressed under the action of external force to act on the exhaust assembly and unblock the air outlet hole. The main cap restricts the pressing assembly from positioned at two longitudinal positions different in height. The present invention has the advantages of need of only pressing the pressing component when disconnecting the cup cap from the cup body, and simple and quick disconnection operation.

A stopper configured to hermetically close a nozzle intended to contain a biopharmaceutical fluid with a cylindrical bore of diameter (D1) and a flange having a groove. The stopper has a body with a front part with a cylindrical outer wall about an axis A, with a diameter at rest greater than (D1), intended to be received under stress in the cylindrical bore of the nozzle, a stop disc extending a rear part of the body radially towards the outside and extending in a plane transverse to the axis. The body and the stop disc are rotationally symmetric about the axis A. The stop disc includes an annular bulge, interposed radially between a first annular shoulder and a second annular shoulder, the bulge extending forward from the stop disc and being intended to be received in the groove in the flange of the nozzle.

A bottle includes a neck and an opening at an end of said neck. A closure member closing the opening is provided with locking means that secure the closure member to a rim of the opening. The locking means include a collar surrounding a neck portion of the neck and locking-levers that are hingedly connected to the collar. The closure member includes outwardly extending lugs that register with the locking-levers. The locking-levers include link members that releasable engage the lugs at a top surface thereof. The locking-levers are retractable to a closed position in which the link members clamp the closure member to the rim of the opening.
