A bottle assembly is provided including a bottle having an end portion with a first detent formation, and a collar having a second complementary detent formation. The collar is arranged to snap fit to the end portion by engagement of the detent formations by application of force only in a direction towards the bottle. In addition, a valve assembly for use with a drinking vessel is provided including a base member and a sealing member. The sealing member is movable, dependent on a pressure difference across it, between a sealed position, wherein the sealing member is sealed against the base member, and an unsealed position, wherein the sealing member is unsealed from the base member. One or more channels are formed between the base member and the sealing member and are arranged to allow air to enter the drinking vessel when the sealing member is in the unsealed position.

A thermally efficient container system having a lid and a base that has a chamber to include a frozen product, or a hot product. The container system includes an outer container including an outer tub and an outer lid. The outer lid can be coupled to the outer tub via one or more hinges. The container system also includes an inner container including an inner tub configured to fit into the outer tub and form a first cavity between at least a portion of the inner tub and the outer tub, and an inner lid configured to fit within at least a portion of the outer lid and adjacent to a proximal surface of the outer lid forming an enclosed second cavity between the inner lid and the outer lid. The container system can include one or more locking assemblies that are configured to secure the lid to the base.

A beverage container closure or lid adapted for closing an open end of a beverage container. The lid is 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 opened by pressing a button disposed on a side of the beverage container closure. The stopper is subsequently automatically closed when the button is released. Thus, the 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. The beverage container closure includes an actuating lever configured to press the button when a user applies a force to the lever. By utilizing the mechanical advantage provided by the lever, a user is able to selectively open and close the stopper using a relatively low amount of force.

A lid assembly including a camming lever and a sealing member for selectively sealing and unsealing a drinking aperture of a lid main body. The camming lever is rotatably to selectively move the sealing member between a sealed position adjacent to and an unsealed position spaced apart from the drinking aperture. The camming lever includes a lever arm extending from two cams having a cam axle extending therebetween. The cam axle is pivotally attached to the sealing member, which is pivotally attached to the lid main body. The cams engage an upper surface of the lid main body. A stub axle extends laterally outward from each cam and engages a ledge which limiting upward movement of the cams.

A lid for use with a beverage container. The lid has a body with a drink opening, a drink opening stopper operable to transition between a closed position and an opened position, and a lock actuator manually rotatable between a locking position preventing the drink opening stopper from transitioning from the closed position to the opened position when the lock actuator is in the locking position and an unlocking position permitting the drink opening stopper to transition from the closed position to the opened position when the lock actuator is in the unlocking position.

A wet sheet storage container. A plurality of male thread parts for screwing a lid body in the circumferential direction are formed on the outer circumferential surface of an upper end part of a container body, and a plurality of female thread parts for threadedly engaging with the male thread parts are formed on the inner circumferential surface of the lid body. The male thread parts are each provided with a base end part formed on the upstream side in the rotation direction of the lid body during installation of the lid body, and a tip end part formed on the downstream side in the rotation direction of the lid body, and the male thread parts are formed such that the height of the tip end part is greater than the height of the base end part.

A non-spill drinking container lid device comprising a collar, a sealing element, and a twist fastener that may be assembled and then attached as a lid device to a drinking container. When a person wants to drink from the container, suction by the mouth and compression by a person's lip causes the sealing element to separate from the collar and allow liquid to flow. The twist fastener provides for adding contents to the container without removing the sealing element or collar.
