Abstract
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.
