According to the disclosure, a closing disc is provided for closing openings, in particular in motor vehicles. It comprises a plate-shaped carrier body made of a hard component with a covering side and a closing side, and a soft component arranged on the closing side, wherein the soft component is formed from a heat-activatable adhesive material, and wherein the closing disc is free of latching means or comprises no latching and/or fastening means.

A fluid end, includes a plunger reciprocating within a first bore, the plunger increasing a pressure of a fluid within a pressure chamber. The fluid end also includes a second bore. The fluid end further includes a plug assembly associated with the second bore. The plug assembly includes a plug body positioned within the second bore. The plug assembly also includes a lock ring positioned, at least in part, within the second bore, the lock ring positioned to be driven radially outward responsive to a longitudinal force applied to the plug body.

A hole plug includes a cap and a securing frame. The securing frame extends from the cap. The securing frame includes first and second support legs, first and second connectors, and a lock body. The first connector is engaged with the first support leg. The second connector is engaged with the second support leg. The lock body is engaged with the first and second connectors

A keg/cask seal for a keg or cask containing a beverage is disclosed. A color mark is arranged in a geometrically defined shape on a top side of the keg/cask seal. The geometrically defined color mark allows a conclusion to be drawn about the time lapsed since the keg/cask seal was installed.

Disclosed is a closure with a first body of a first metal with a first electrode potential, and a second body of a second metal with a second electrode potential different than the first electrode potential. The first and second bodies are joined together along a connection interface between the first and second bodies to form the closure separating a first space on a first side of the closure from a second space on a second side of the closure. The connection interface extends from the first side of the closure to the second side of the closure, and includes a close-coupled portion and a seal portion between the first side of the closure and the second side of the closure. A polymer film is disposed between the first and second bodies along the close-coupled portion of the connection interface.

A seal cover (1) is provided for closing an annular opening portion (10) that has locking projections (14) on an outer peripheral surface of the opening portion (10). The seal cover (1) includes a fitting (22) having a seal ring (23) fit on an outer peripheral surface and locking portions (24) configured to be pushed and resiliently deformed by the locking projections (14), to move over the locking projections (14) and to be locked to the locking projections (14) when the fitting (22) is fit into the opening portion (10). Tapered surfaces (27) are formed on front end parts of the locking portions (24) and are disposed in a connecting direction for delaying a time point (T2) when the locking portions (24) are maximally resiliently deformed from a time point (T1) when the seal ring (23) is compressed maximally when the fitting (22) is fit into the opening portion (19).
