The present invention discloses a rotatable lid and a drinking cup having the rotary lid. The rotatable lid comprises a lid body (1), a rotating knob (2), a water stopper (3), a moving component (4); the lid body (1) has a shaft hole (11), a water outlet (12), and an air inlet (13); and the water stopper (3) has a water outlet sealing portion (32) and an air inlet sealing portion (33). Pushing the rotating knob (2), the moving component (4) can move together with the rotating shaft (21) of the rotating knob (2) relative to the water stopper (3), the locking portion of the moving component (4) driven by the rotating shaft (21) can move on the locking track (34) to press upward the water stopper (3). Therefore, the water stopper correspondingly seals both of the water outlet and the air inlet on the lid body. In this way, the water outlet on the rotary lid is closed. It is convenient for a user to operate.

A container system includes an outer container including a hollow interior, and a container insert positionable in the hollow interior of the container body. In one aspect, the container insert extends between a first end and an opposite second end and includes a generally cylindrical portion and an out-of-round portion positioned adjacent to the generally cylindrical portion. The out-of-round portion is enlarged relative to the generally cylindrical portion and configured to engage with a portion of the container body when the container insert is positioned in the hollow interior of the container body to provide a press fit between the container body and the container insert. In this or another aspect, the outer container includes a lateral opening and the container insert includes a flange which extends across at least a portion of the at lateral opening when the container insert is positioned in the hollow interior.

A container includes a bottom box and a top lid. The bottom box includes a containing space adapted to contain the contents. The bottom box has a tilted shape wherein the bottom box has one side height greater than another side height. The top lid includes an integrally formed lens and formed with a plurality of air holes on a top surface thereof. The top lid is removably assembled with the bottom box.

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. The closure body further includes a circular valve seat within the center portion of the deck, and a plurality of vent openings circumferentially spaced within the valve seat. 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 beverage container closure or lid that is adapted for closing an open end of a beverage container. The lid is selectively couplable to the beverage container and includes a selectively openable stopper that when closed, creates a fluid-tight seal between the beverage container and the environment. The stopper may be selectively opened by a user by the user pressing a button disposed on a side of the beverage container closure. The stopper is subsequently automatically closed when the user releases the button. Thus, a user may open and close the beverage container closure using a single hand without the need to remove the beverage container closure from the beverage container.

A child-resistant closure having inner and outer caps cooperating as a nested shell is contemplated. Downward force applied to the closure engages a series of cooperating lugs and detents to engage the child resistant feature, while thinned walls and cooperating, ramped skirts on the shells' interfacing surfaces to improve the hoop strength along a predefined circumference to avoid stripping/disengagement of the threads on the closure and container neck. An optional tamper evident ring may also be provided, as well as a combustion resistant vent formed in the top panel of the inner shell.

An insulated container having a canister can be sealed by a lid structure. The lid structure can be a multi-part insulated lid. The lid can include a vent configured to vent air from inside the canister. In addition, the container may be part of a container kit or container system where one or more inner containers, are nested and secured within the insulated container.

The present invention relates to a method for channeling gas during sealing a container with a closure means and/or unsealing a container that is sealed with a closure means, comprising the steps of: A) providing a closure means comprising: a) a lid assembly having: a lid cover, configured to provide an upper plate and a lower plate connecting said upper plate via standing wall therebetween, said upper plate is provided with at least one hinge member; at least one wing member, pivotably connecting to said lid cover at said hinge member, comprising a handling portion, a flipping portion, and a stopper portion for limiting the upward pivoting of said wing member with respect to said lid cover by engaging with said upper plate of said lid cover; and a gas channeling means; and b) a sealing element, fittingly mounted around said standing wall of said lid cover; and B) providing a container having surrounding wall having a first edge connecting to a bottom and a second edge defining an open-top for said container, wherein said second edge is configured to support said flipping portion of said wing member; and characterized in that, gas being channeled through said gas channeling means, during closing said container with said closure means and/or opening said container that is closed with said closure means.

Disclosed are a container cover and a vacuum preservation container. The container cover comprises a cover body and an air extraction assembly, wherein a first through hole is provided in the cover body, the air extraction assembly comprises an outer cover and an inner cover, the inner cover is arranged on an upper end of the first through hole in a sealing manner, a second through hole and a third through hole are provided in the inner cover, the second through hole is in communication with the first through hole, a first one-way valve is arranged in the second through hole, and a second one-way valve is arranged in the third through hole.

The invention relates to a cap for closing containers comprising at least one mesh, one foamed polymer and at least one further polymer, and to containers equipped with the cap of the invention.
