A stopper for a container has a jacket portion insertable into the container, wherein the jacket portion has a through-opening formed in an axial direction, wherein the stopper has at least two segments, wherein the respective segment has a free end, wherein a first portion of the free end of the respective segment forms a subregion of the jacket portion, and a second portion of the free end of the respective segment protrudes radially inward in relation to the jacket portion, wherein a third portion of the free end of the respective segment protrudes radially outward in relation to the jacket portion, wherein the second portions form a cover portion that can be pierced through in the axial direction and that closes the through-opening, wherein the third portions form a bearing portion of the stopper for bearing against a container edge of the container.

A decanter system can include a decanter and a stopper. The decanter can include a decanter body and a neck. A mouth can be formed in the neck. The stopper can include a sealing member. The stopper can be configured to be selectively disposed in the mouth to form a seal between the sealing member and the mouth. The stopper is positionable in the mouth between a first position and a second position where the seal is maintained in each of the first position and the second position. A method of storing liquid can include providing a decanter system. A liquid can be disposed in the decanter body. A filter with flavoring materials disposed therein can be placed within the decanter body. The decanter can be sealed with the stopper in the first position. The stopper can be pushed downwards in the mouth to the second position, repeatedly as desired.

This utility model released one kind of multifunctional flexibly transformable cup, comprising one internally cut-through transformable cup and a nested bottom plug that is sealed and clamped with the transformable cup body. The above-mentioned transformable cup is comprised of a foldable enclosure and pin that are successively cut-through and flexibly and tightly connected. The aforesaid seal clamp for embedded bottom plug is located at the junction between the foldable enclosure and pin. When the multifunctional flexibly transformable cup of the utility model is in use, the folding enclosure body can be overturned freely, and the whole body is made of food-grade flexible silica gel material, which is safe and reliable and not easy to be broken. It can also be used as the wine cup, bottle stopper and the bottleneck inserted into the wine bottle that can be directly used for drainage of fluid, with complete functions.

A self-venting self-resealing pre-cut elastomeric closure for vials, bottles and the like, comprising a dished elastomeric septum supported for closing an opening in a container, a cut across the dished elastomeric septum, and additional cuts defining with the cross cut one or more flap areas elastically displaceable from a closed condition to a venting condition in response to insertion of a liquid transfer implement through the central area of the septum dish.

Cork inserts for friction fit caps have advantages over conventional thermoplastic inserts. These include: a unique sensorial feel for the user; avoiding the expenses associated with tooling and molding of plastic inserts; and reducing the amount of plastic in the waste stream. The cork insert is particularly attractive when used with caps that are made of natural materials, but can also used to reduce the carbon footprint of any cap that would otherwise us a plastic insert.

A temporary plug apparatus for use to seal a port in an upper manifold or lower manifold corresponding to a damaged filter grid in a pool filter system is provided. The plug apparatus includes a main body having a central body, an upper tubular member designed to insert into one of a plurality of ports in the upper manifold and a lower tubular member designed to insert into one of a plurality of ports in the lower manifold, and an elastic band coupled to the main body and designed to wrap around the upper manifold or lower manifold of the pool filter system to ensure the upper tubular member or lower tubular member of the main body is secured to the one of the plurality of ports in the upper or lower manifold.
