A liquid storage tank includes a housing, a piston, a lower cover, an elastic element, and an outlet pipe. The piston is located in the housing. The lower cover is attached to the housing and has a support post extending toward the piston. The piston, the housing, and the lower cover define a tank chamber. The elastic element is connected with the tank hosing and the piston. The outlet pipe communicates with the tank chamber.

An apparatus is provided having an open configuration and a closed configuration. The apparatus includes, while in the closed configuration, a first panel, a second panel, a third panel, a fourth panel, a fifth panel, and a sixth panel that together create a box partially enclosing a void space. The first panel is rotatably coupled to the fifth panel and the sixth panel, the second panel is rotatably coupled to the fourth panel and the sixth panel, and the third panel is rotatably coupled to the fourth panel and the fifth panel. The apparatus opens from the closed configuration to present the contents therein through a single degree-of-freedom mechanism where the first, second, and third panels become perpendicular to the fourth, fifth, and sixth panels while the fourth, fifth, and sixth panels become aligned in a same plane.

A firelighter cage (10) comprising a first side member (12) including a first wall portion (18) formed from a rigid mesh defining a first cavity (22) and a second side member (14) including a second wall portion (19) formed from a rigid mesh defining a second cavity (23). Connectors (24) are provided on a first edge portion (20) of the first side members (12). When the first and second edge portions (20, 21) are aligned and engaged against each other, relative rotation of the first and second side members (12, 14) causes the connectors (24) to engage with a second edge portion (21) of the second side member (14) such that the first and second wall portions (18, 19) define a chamber (16) for receiving firelighters (11).

A container including a rigid base and one or more rigid lateral walls, the lateral wall being perimetrically continuous, such that the lateral wall and the base define a cavity. The cavity allows for the storage and transportation of contents, such as sand, rocks, building materials, paints, and other liquids. The container includes a set of flanges on an exterior side of the one or more lateral walls, with the flanges providing attachment points for a set of handles. When the set of handles are secured to the flanges, a user can easily grip the handles to transport the container to a new location. In addition, the container includes a circumferential lip that extends below the base, such that a user can easily grasp the lip at different locations to maneuver the container, without forcing the user to grip a specific handle on the bottom of the container.

A first score line (430) is curled inward at one end section (431) and the other end section (432) of the first score line (430) so as to go into a region enclosed by the first score line (430), and the first score line (430) approaches a center line (CL) of a tab as going to the trailing ends thereof. In addition, a curvature at which the first scored line (430) is brought closer to the other end section (432) side is applied to the one end section (431) of the first score line (430), and a curvature at which the first score line (430) is brought closer to the one end section (431) side is also applied to the other end section (432) of the first score line (430).

A can (1) is provided with a mouth part (4), a shoulder part (3), and a body part (2). The shoulder part (3) of the can (1) is decorated, without damaging the shoulder part (3), by forming at least one of a recess and a protrusion by means of a rotating process in which the shoulder part (3) is held between a receiver (11a), having a concave-convex shape, of an inner roll (11) and an outer roll (12) having a convex-concave shape corresponding to the concave-convex shape of the receiver (11a) of the inner roll (11).

Devices for cooling beverages in cooperation with a compressed gas cartridge. The devices include a housing, a head, a working fluid, and a release mechanism. The housing defines a chamber complementarily configured with the compressed gas cartridge to receive the compressed gas cartridge. The head couples to the housing and defines an interior void in fluid communication with the chamber. The working fluid is contained with the interior void of the head. The release mechanism is operably connected to the housing and configured to selectively release compressed gas from the compressed gas cartridge into the interior void of the head. The compressed gas cools the working fluid when the compressed gas is selectively released from the compressed gas cartridge and contacts the working fluid in the interior void. The head is configured to be placed in a beverage to cool the beverage.

The present invention relates to a self-carbonating beverage container, comprising: a) beverage can housing adapted to hold to hold a fixed portion of liquid; b) a carbonating gas bottle containing carbonating gas stored under pressure having a breakable seal through which said carbonating gas is released, wherein said carbonating gas bottle is attached to said can; and c) a spout attached to said can such that one end of said spout is introduced into the beverage can housing and the spout other end comprises puncturing mean and it faces the breakable seal of said carbonating gas bottle, wherein actuating said puncturing mean enables the carbonating gas to flow into the beverage can housing.
