A container that seals in a volume of material is provided. The container may be routinely opened, closed and material may be removed or added. A removable plate and a base define a maximum volume available for material when the container is sealed. A screen may be disposed between the plate and the base. The screen may optionally be comprised within the base, adhered to the base, or removable from the base. Features for enabling manipulation of the plate and/or screen are optionally provided.

The present application is directed to cap assemblies and particularly, cap assembly for closing an opening in a vessel, the cap assembly including a stopper including an polymer body adapted to fit an opening of a vessel, the stopper also including a tubular portion which defines an internal passageway extending through the polymer body; and a rigid cap attached to and integral with the stopper, wherein the cap is adapted to engage the vessel and provide a sealing force between the stopper and the vessel.

A wine bottle stopper is provided including a vacuum stopper and a removable decorative cap. The vacuum stopper includes a central conduit extends longitudinally through the vacuum stopper, and a one-way valve is located within the central conduit. The vacuum stopper includes an upper portion which extends exterior to the wine bottle and a bottom shaft sized for insertion into a wine bottle's opening. The vacuum stopper also has a release valve connected to the one-way valve. Meanwhile, the decorative cap has a sidewall and a top wall forming a central cavity sized to engage and cover the vacuum stopper's upper portion.

The embodiments of the present disclosure provide a stopper comprising a plug and a pierceable membrane, the plug including a cavity between a pierceable membrane and a lower opening. The pierceable membrane and the cavity can form a tortuous path that reduces interactions between the contents of the container and the ambient environment. The cavity can be bounded by a plastic insert disposed within the plug. The plastic insert can include insert walls, the lower opening, and an insert flange. The pierceable membrane can be bonded to an upper surface of the insert flange.
