A rigid stopper (10) made of synthetic materials, particularly for wine bottles, comprises a substantially cylindrical body (12) defining a longitudinal axis (20), with a side surface (14) and two opposing substantially flat end faces (16, 18), and at least two compressible-elastomeric “O”-rings (22, 24) seated in corresponding semicircular-circumferential-grooves (26, 28) on the side surface (14). The semicircular-circumferential-grooves (26, 28) are positioned symmetrically about a central-plane (56) toward faces (16, 18) of body (12) respectively. Faces (16, 18) are comprised of foramen (42, 44) respectively which communicate with a volute cavity (14) for the purpose of accepting a typical cork-screw-extractor. Stopper 10 having longitudinal symmetry about a central plane (56), either face (16) or face (18) of stopper body (12) is configured to rest flush with bottle (48) top for the purpose of maintaining compatibility with random orientation of the stopper 10 with the “corking” process of packaging machinery. A predetermined diameter (32) of stopper body (12) is slightly less than the interior neck (54) of bottle (48) for the purpose of allowing the “O”-rings (22, 24) to be compressively engaged between the stopper body (12) and interior neck (54), thereby sealing and maintaining position by means of friction of stopper (10) within bottle (48). The two compressible-elastomeric “O”-rings (22, 24) are made of a different material of that of the cylindrical body (12). The material of the compressible-elastomeric “O-rings (22, 24) is non-toxic food-grade silicone rubber having a formulation able to ensure complete compatibility for alimentary use and a high resistance to aging. The material of the cylindrical body (12) is a rigid thermo-plastic bisphenol-free polycarbonate, a non-toxic category having a formulation able to ensure complete compatibility for alimentary use and a high resistance to aging.

Stopper body (12) is much more durable, sanitary, dependable, and reusable than the traditional cork or synthetic cork stopper. As compared to the recent screw cap, the stopper (10) maintains the mystique, romantic charm, and quality image of an expensive wine, whereas the screw-cap gives connotation as being of lesser quality wine and has low tamper resistance.

The present invention relates to a cap for covering an opening of a container, preferably the opening of a bottle. The present invention is characterized by a cork body having a cylindrical configuration and configured in two portions between which there is arranged an impermeable sheet element according to the longitudinal direction. The presence of an impermeable sheet allows using a conventional closure material preventing permeability in the longitudinal direction both to prevent the liquid from coming out of the container and to prevent bacteria or contaminants from the outside from entering.

A freshness plug includes a solid round body having an internally depressed section, a protrusion extending from the internally depressed section, a shoulder extending from an exterior of the internally depressed section, and malleable flanges below the shoulder.

Disclosed are caps for closing an opening in a lid for a container, such as a paint can or bucket, wherein the caps comprises top walls comprising on their top surfaces centrally disposed recesses configured to receive a tool to rotate the caps; and threaded cylindrical projections on their bottom surfaces.

An auto-lock sealing valve structure of a rubber jointing ring using the lid attached to the rubber jointing ring includes a lid, a rubber jointing ring, and a bottle body. The rubber jointing ring connects the lid and the bottle body. The designation of the vapor escaping groove in the lid body helps the air inside the rubber jointing ring escape out, simultaneously the raised edge on the bottle lid prevents the rubber jointing ring part from coming out off. The gaps on the body part of the rubber jointing rings help the air inside the bottle body to entirely escape but still ensure that the liquid inside the devices cannot escape.

A cork screw bottle lock is used to secure a cork within a bottle and to facilitate removal of the cork from the bottle using a screw on/off mechanism. A cork screw bottle lock may include a retainer configured to secure a cork onto a bottle by a screw-on attachment of the retainer to the bottle. A method may include adding contents to a bottle and sealing the bottle using a cork secured to the bottle using a cork screw bottle lock.

The invention relates to a plastic container that is blown in a blow mold, having a body, defining an opening is provided, and a disposable closure, which closes the opening and is formed in the blow mold together with the body. A holding strip with a first end and a second end is also formed in the blow mold together with the body and the disposable closure. The first end is permanently fixed to the body, and the second end is permanently fixed to the closure. The body, the disposable closure, and the holding strip are formed as a single piece.
