Abstract
A stopper for a food jar is described that may be used to store and transport food items. The stopper includes a bottom wall and a sidewall. The stopper includes one or more vent passages connecting the bottom wall and the sidewall to provide pressure relief. A vent gasket is provided at the bottom wall that opens when pressure inside of the container is elevated to allow air to pass into the vent passages and vent outside of the container.
Claims20
A stopper for a food jar, comprising:
- a stopper, the stopper configured to close an opening of a container;
- the stopper includes a top wall, a bottom wall, and a sidewall, wherein the top wall is generally opposite of the bottom wall, and the sidewall joins the top wall and the bottom wall;
- a central recess formed in the bottom wall;
- one or more vent passages passing through an interior of the stopper;
- the one or more vent passages have a first opening at the central recess and a second opening in the sidewall;
- the one or more vent passages connect to the central recess and to the sidewall;
- and
- a vent gasket configured to position in the central recess, the vent gasket configured to selectively open and close the one or more vent passages in response to a pressure differential between an ambient atmosphere of the container and an interior of the container.

A stopper for a food jar, comprising:
- a stopper, the stopper configured to close an opening of a container;
- the stopper includes a bottom wall and a sidewall;
- a central recess formed in the bottom wall, the central recess includes a cylindrical wall defining a void;
- one or more vent passages connecting the central recess and the sidewall;
- a positioner that extends from the bottom wall and into the void of the central recess;
- a vent gasket configured to at least partially fit into the void of the central recess;
- the vent gasket comprising a cylindrical portion;
- the cylindrical portion of the vent gasket defining a central open portion configured to receive the positioner, wherein an exterior surface of the cylindrical portion includes one or more fins configured to seal against the cylindrical wall of the central recess;
- and
- the cylindrical portion comprising a flexible gasket flap configured to touch or seal against the positioner, the flexible gasket flap configured to deflect or bend in response to a pressure differential between an inside of the container and an ambient atmosphere of the container, thereby releasing pressure.

- a vent gasket configured to at least partially fit into the void of the central recess;
- the vent gasket defining a central open portion configured to receive the positioner;
- and
- the central open portion comprising a flap configured to seal against the positioner and to automatically open under higher than ambient pressure conditions to relieve pressure.
