A lid assembly for a drink container is provided. The lid assembly can include a lid and a slider. The lid can include an opening through which a liquid is selectively dispensed. The slider can selectively reveal the opening by sliding along the lid. The slider can include a first slider portion that can slide along a first surface of the lid and a second slider portion that can slide along a second surface of the lid.

A cap includes: a cap body including a top plate portion and a cylindrical skirt portion; a sealing member provided in the cap body separately from the cap body so as to face the top plate portion; a plurality of locking portions arranged in a circumferential direction in the skirt portion, the locking portions protruding inward in a radial direction of the skirt portion and supporting the sealing member; a plurality of small diameter portions arranged between the top plate portion and the locking portions of the skirt portion, the small diameter portions being respectively provided on a top plate portion side of the locking portions in the axial direction; and a plurality of large diameter portions provided adjacent to the small diameter portions in the circumferential direction and having an inscribed circle diameter larger than an inscribed circle diameter of the plurality of small diameter portions.

A self-venting closure assembly includes a closure body having a deck with a peripheral mounting skirt and an annular seal on an underside of the deck adjacent to the peripheral mounting skirt, further including a circular valve seat within the center portion of the deck, and a plurality of vent openings circumferentially spaced within the valve seat, all surrounded by an annular spillover wall. An elastomeric umbrella valve is centrally mounted to the deck and has a frustoconical valve flap arranged on an underside of the valve seat. The valve flap cooperates with the vent openings to normally seal the vent openings but permits air to flow into an interior of the closure body when a vacuum is applied to an interior of the container on which the closure is mounted.

A container system comprises a container with a storage compartment and a lid assembly to seal the container. The lid assembly includes an upper portion and a lower portion that are moveably coupled to one another. The upper portion includes a vent gasket that contacts the lower portion to seal a vent opening in the lower portion, and the lower portion includes a lower gasket to seal the lower portion to the container. When removing the lid assembly, the upper portion is moved relative to the lower portion a predetermined amount causing the vent gasket to be free of contact from the lower portion creating a vent path for air to escape from the storage compartment.

A portable blender includes a container with a chamber and an opening to the chamber. A lid/base is arranged to be coupled to the container and seal the chamber. The has a power source, a motor, a control, and a blade assembly, with the blade assembly oriented toward the chamber. The lid/base also has a pour spout and a vent which both open into the sealed chamber. A closure mechanism is provided for sealing the pour spout and vent, with a stopper configured to cover the pour spout and a vent cover configured to cover the vent. The closure mechanism is arranged such that stopper movement governs vent cover movement, with stopper movement away from the pour spout causing vent cover movement away from the vent, and stopper movement to cover the pour spout moves the vent cover to cover the vent.

A cap (1) comprising a base body (2, 2) is endowed, on one of the internal sides thereof, with a thread (3), a seat (4) in which a seal (5) is housed at least partially, and a liner (6) fitted onto the base body (2) and torsionally fastened thereto, which completely conceals the base body (2) from lateral views and in at least one plan view.
