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 stopper for closing sparkling and other non-pressurized beverage containers. A stopper body may have a carrier member and lip engagement member arranged for sliding movement relative to each other and relative to the stopper body. The lip engagement member may be arranged to engage with a lip of a container neck, and be resiliently biased to move toward the carrier member to provide a seal-forming force on a sealing surface of the stopper body. The stopper may be arranged to introduce gas into the container, e.g., to re-pressurize the container to keep a carbonation level of beverage during storage.

Systems and methods for storing a liquid include a container including a body portion defining an internal chamber and at least one opening in communication with the internal chamber, and an insertable plug including a plug body with two rings attached to the plug body via hinges, the insertable plug configured to be inserted into the opening so that a portion of the plug body covers a lip of the opening to restrict access through the opening to the liquid contained in the internal chamber, wherein the hinges can be deformed to raise the two rings away from the plug body. An insertable plug for a container can include a cylindrical plug body, and two rings attached to the plug body by hinges, wherein the hinges can bend to orient the rings towards or away from the plug body.

A beverage-packaging container is provided that includes a container body for receiving the liquid and a cork stopper for sealing the liquid contents within the container body. The sidewalls and bottom wall of the container body are formed of paperboard and are preferably formed of a layered, recycled paperboard. The top wall of the container body is formed of a cork material with a cork-receiving hole disposed within the top wall. The cork stopper has a truncated cone-shaped portion that is configured to engage frictionally with the edges of the cork-receiving hole. The cork stopper may also have a wooden crown to aid the user in grasping and removing the cork stopper from the top hole of the container body.
