The present disclosure provides a cap plate and a secondary battery. The cap plate includes a main portion and a first protruding portion. The main portion includes a first exterior surface, a second exterior surface and a third exterior surface, the third exterior surface is a curved surface. The first protruding portion includes a fourth exterior surface extending downwardly from a bottom end of the third exterior surface, the fourth exterior surface is inclined inwardly relative to the third exterior surface. The secondary battery comprises the cap plate and a case. The case includes an opening; the cap plate is provided to the opening, the main portion is fixed to an inner wall of the case. The first protruding portion is received in the case, and a gap is provided between the fourth exterior surface and the inner wall, a dimension of the gap increases gradually along a downward direction.

A dispensing system for use with a portable container for the storage, transport, and dispensation of fluids, especially liquids. The dispensing system includes an annular collar affixable to such a portable container. The collar is matable with a twist-top having a straw thereon. Once mated, corresponding structures on the collar and twist-stop prevent or inhibit separation. The twist-top can be twisted open to a position in which corresponding interior structures of the twist-top and collar form a fluid channel allowing liquid in the container to flow past sealing elements such as a gasket, and to egress to a contoured surface for sipping hot liquids by a human. The twist-top can be twisted close to reseal and inhibit fluid egress. Alternatively, a rotatable flip straw in the twist-top can be opened to drink cold liquids from the container while the twist-top is sealed in closed position.

The puzzle storage box disclosed herein may comprise an internal locking mechanism designed to challenge ingenuity while being embedded within an assembly of unlimited form potentiality. In one variation, the internal locking mechanism is embedded in a shallow container and may be used for more personal, everyday carry. In another variation, the internal locking mechanism is embedded in a deeper container for increased volume and prominent display. The internal locking mechanism will be incorporated into endless shapes and forms, and its novel method of operation will be respectively conveyed.

A container apparatus having at least one containment member is disclosed that may include a bottom and at least one sidewall, an interior and an open end. The container may also include a flange that extends around a free end of the at least one side wall, and a plurality of wall members (or castellations) connected to/formed with/that extend from the flange. The plurality of wall members may be separated by ventilation apertures, with the plurality of wall members and the ventilation apertures extending around the perimeter of the free end. A sealing material, such as a removable film, may extend over the open end to enclose the containment member.

A base assembly for a ball display case includes a base configured to support the display case on a surface. A pedestal is supported by the base and configured to support the ball in the display case. The pedestal includes a platform for seating the ball in the display case. The platform includes a spring configured to yield when contacted by the ball in the display case.

A drink container and plug lid for use therewith. The lid has an upper member and a lower member with a ring seal positioned therebetween and radially outwardly stretchable from an initial diameter to a larger sealing diameter in response to an actuator moving the upper and lower members together to place the ring seal in fluid-tight sealing engagement with the container body. Moving the upper and lower members apart allows the radially outward stretched ring seal to move from the sealing diameter to the initial diameter whereat it is out of fluid-tight sealing engagement with the container body.

The closure adapted to cover a container aperture defines a retention projection dimensioned to be received in a retention aperture in a wall of the container. An insertion surface on the projection avoids the closure being impeded by an edge of the wall. The projection defines a disengagement surface to remove the projection from the retention aperture and defines a registering surface opposite the registering surface. The closure may be fitted agnostic to the rotational alignment of the closure relative to wall and then twisted relative to the container until resistance is provided by the registering surfaces engaging Automated closure requires only two degrees of movement and only two force sensors.

A household tissue paper container includes a container body that is configured to store household tissue paper therein and has a take-out portion having an outlet through which the household tissue paper is taken out; and an open/close lid that is pivotably attached to the container body and closes the outlet. The outlet is formed at a swelling portion having a substantially spherical raised shape in the take-out portion. The outlet has a protruding piece that is protruding from a front edge of the outlet toward a rear where the open/close lid is attached to the container body.

A container includes a base and a cap that engages a portion of the base. The base has a body portion and a neck portion, where the neck portion defines an open end. The cap has a housing and a hinged lid. The housing defines an open cavity in the cap, and the neck portion extends into the open cavity. The hinged lid is movable between an open position providing access to the cavity and a closed portion sealing the cavity.

A bowl assembly has a bowl and a lid. The bowl assembly is adapted to store water or food for a pet. The bowl functions as a container to hold the water or food, while the lid functions in a first configuration to seal the water or food within the bowl. The bowl assembly is convenient to travel with and adapted for use in a vehicle where in the first configuration. The bowl assembly allows for the pet to access the water or food while in a cup holder. The bowl assembly is also stabilized by the lid in a second configuration, where placed on a ground or floor surface.
