A closure may have a top wall and a side wall depending from the top wall. A plug seal device may depend from said top wall within the side wall. The plug seal device may have an upper section, a lower section, and a sealing section proximate the boundary between the upper section and the lower section. The sealing section is operable such that when the plug seal device is inserted in an opening to an inner cavity in a container, the sealing section engages with an inner container surface to provide a seal between an inner cavity of the container and the external environment.

To provide a rubber stopper capable of suppressing occurrence of coring. Provided is a rubber stopper including a canopy portion having an upper surface and a lower surface, and a leg portion provided on the lower surface of the canopy portion, in which the leg portion has a tapered base portion at the center on a lower surface side of the canopy portion, and a curvature radius R1 of the tapered base portion is 2 mm or more and 4 mm or less.

A storage vessel is provided comprising a vessel body, a vessel plug, and at least one commemorative element. The vessel body has a bottom securely joined to a domed top to define an interior chamber accessible through an opening defined on the bottom. The vessel plug secures the opening and may be obscured during use to disguise the opening. The at least one commemorative element comprises a rod with a star mounted on its distal end, extending off the domed top. The vessel may further comprise an ornamental structure extending off the domed top and an identifier. The vessel may be used as an urn, and the interior chamber may be used to accommodate the remains of loved ones, including small and large pets.

A container for pourable foodstuffs has a base, a side wall connected to the base and surrounding a storage chamber. An elastic cuff is connected with a first end to the side wall and has a second end with an opening. The cuff width decreases from first to second end along a longitudinal container axis. The elastic cuff can be pushed into and pulled out of the storage chamber. A sealing element shaped as a stopper can be inserted into the opening for closing the container and has a shank portion matched in shape and size to the opening such that sealing abutment of a shank portion surface against surfaces of the elastic cuff adjoining the cuff opening is established in a contact region of the shank portion when the stopper is inserted. The shank portion has an end with a thickened portion thicker than the contact region.

A closure for beverage containers that have a substantially cylindrical neck with an end opening and a closure cap includes a neck with an inside circumferential detent collar and a closure cap having an insertion shaft. A circumferential detent groove is provided on an outer circumference of the shaft. The detent groove corresponds to the detent collar, is profiled in a direction of insertion, and engages over the detent collar on a ring surface thereof that lies in the direction of insertion.

Described herein is an improved bottle and lid design that eliminates the need for lids on bottles that require unscrewing, snapping, or other exertion to remove and/or replace the lid.

A reusable bottle cap system includes a bottle cap and a bottle cap cover. The bottle cap includes a proximal handling portion and a stem that extends from the proximal handling portion to a distal end. The stem has opposing outside and inside surfaces. The outside surface includes a sealing feature for sealing to the mouth of a beverage bottle. The inside surface defines an opening extending to the distal end of the stem. The shell has an inside surface defining a cavity that is closed at a distal end. A pin extends from the distal end of the inside surface of the shell. The pin is received into the opening of the stem to provide a holding force to secure the bottle cap cover to the bottle cap.
