A closure can close an outlet of a vessel. The vessel outlet can comprise a tubular cavity with an interior surface. The closure can comprise a male portion comprising a distal undersized portion, a proximal oversized portion, and a taper between the undersized and oversized portion. The male portion can be inserted in the vessel outlet, undersized portion first. Interference between the inner diameter of the vessel outlet and the outer diameter of male portion can occur when the male portion is sufficiently inserted. The interference can cause the undersized portion to flare out and engage the interior surface of the tubular cavity, thereby providing a seal.

The invention relates to a closure system on a fuel tank (2) of thermoplastics with barrier properties for hydrocarbons. The closure system comprises at least one orifice (4), with a closure cap (5) which closes the orifice (4) in a sealing manner and which cooperates in a form-fitting manner with closure means provided at the circumference of the orifice (4) and encloses at least one first sealing means between it and a tank wall (3). The closure system (1) according to the invention is distinguished in that the tank wall is sealed in the region of the orifice (4) with at least one second sealing means, which covers and/or shields a part of the tank wall surfaces exposed to hydrocarbons.

A can comprises a can body (10) and a lid (4). The can body is manufactured using only a single homogeneous piece of material and has an edge that defines a top opening into the can. The can body also has an inwardly directed bead (23), which extends around the body, is adjacent to the can body edge, and defines an inwardly facing sealing surface (24) of substantially constant transverse cross-sectional dimension along an axial extent. The lid defines an outwardly directed sealing surface which abuts the inwardly facing sealing surface presented by the inwardly directed bead in order to seal the lid to the can body. An alternative can body has an inwardly directed pinched or collapsed bead which defines an upwardly facing sealing surface (34) for engagement with a downwardly facing sealing surface of a can lid. The alternative can body additionally has an inwardly directed bead (35) between the can body edge and the pinched or collapsed bead. An outer brim (42) of the lid is configured to be retained between the two beads of the alternative can body.

A container includes a container main body including a housing part and an opening, and a lid configured to close the opening and including an insertion part configured to be inserted to the opening. The outer peripheral surface of the insertion part includes first and second protrusions and first and second recesses. The inner peripheral surface of the opening includes third and fourth protrusions and third and fourth recesses. When the insertion part is temporarily inserted to the opening, the third protrusion presses the first recess in a state where the first protrusion is housed in the third recess. When the insertion part is fully inserted to the opening, the third protrusion presses the second recess and the fourth protrusion presses the first recess in a state where the first protrusion is housed in the fourth recess and the second protrusion is housed in the third recess.

A cap for a pouch including a spout engaging body, a handle member and a multimode handle coupling assembly. The spout engaging body includes a depending skirt defining a central bore configured to engage a spout. The handle member extends from the spout engaging body. The multimode handle coupling assembly includes at least one handle tab formed into the handle member and at least one mode three slot. The at least one mode three slot includes a multi direction slot defined in the handle member having a central opening and a plurality of radial slot portion pairs, to, in turn, sized to receive a handle tab of another cap in a plurality of orientations.

An improved closeable lid for a beverage container is described. The lid uses a base, a flanged gasket, a valve and a knob to allow a user to control the flow of liquid from the beverage container. The flanged gasket surrounds the base with radially extending flanges that conforms to the interior of the beverage container, creating a seal. The valve moves vertically to engage and disengage the seal created by mating the valve face to the valve seat. The vertical movement of the valve is modulated by the rotation of a knob that is connected to the valve that provides a threaded shaft. The user can consume liquid from the beverage container as a result one or more fluid apertures through the base allowing for the passage of fluids from the beverage container past the valve and through base to the user. When the knob is rotated to the closed position, the valve creates a seal preventing the flow of liquid through the fluid apertures of the base.

An array of pressure vessels for storage of a compressed gas includes at least one Type 4 pressure vessel and at least one Type 1 pressure vessel. The Type 1 pressure vessel is in fluid communication with the at least one Type 4 pressure vessel. A metal wall of the at least one Type 1 pressure vessel has a Type 1 thermal conductance that is greater than a Type 4 thermal conductance of the at least one Type 4 pressure vessel.

A beverage lid for temporarily and removeably covering beverage cups and glasses to prevent spillage and contamination. The lid is installed on a drinking glass having an enlarged reservoir with a circular rim. The lid has a circular, planar base with an outer surface, an inner surface, and a diameter larger than the diameter of the glass rim. A central handle is affixed at a proximal end to and projects from the base and has an outer, grasping surface and an inner surface. The handle preferably has a shape that allows the outer surface of one handle to nest in the inner surface of the handle of another of the lids. The lid preferably includes an annular lip or tabs that project transverse to the plane of the base to prevent the lid from sliding off the rim of the glass.

A tube plug insertable in one end of a heat exchange tube, the tube plug formed as an shaft having a distal part and an opposite proximal part which terminates in a proximal end with an threaded hole extending axially in the proximal end in the distal direction, and a plug removal tool having a proximal handle part and a distal stem part which has external threads that match threads in the threaded hole in the plug's shaft, the stem part being threadedly insertable into the threaded hole in the proximal end of the tube plug, whereby rotation of the stem will urge the tube plug to rotate relative to the heat exchange tube and break free from being lodged in the bore thereof.
