摘要： A device for use in connection with tapping off fluid from or filling fluid into a container through an internally threaded tapping or filling hole in the container provided with an externally threaded generally cup-shaped plug having an outwardly open cavity in which a tool may be inserted for rotating the plug. The device comprises a bell-like housing and a tool for manually operating the plug from a position outside the housing. The tool comprises a shaft which extends slidably and rotatably through a portion of the housing opposite to the open end of the housing and which is provided with a handle at its outer end and with a plug holding and operating means at its inner end. The latter means includes an expansion mechanism adapted to be expanded into contact under pressure with portions of the side wall of the cavity of the plug upon insertion of the plug holding and operating mechanism into the cavity.

摘要： A can lid remover comprises a pair of mutually expandable wedge members (17, 23) which may be driven in between an outer peripheral flange (49) of a can and an outer peripheral flange (48) of a lid in adjacent initial positions in which they are located side by side in a common plane and which then may be moved to mutually expanded positions while lifting the lid flange (48) from the can flange (49). In order to facilitate a safe and convenient use thereof, the remover is also provided with a holder-up (24) which is located in front of the wedge members (17, 23) and adapted to be applied against the inner side of a cylindrical wall portion of the lid (47) and which may be moved in relation to the wedge means (17, 23) from an outer end position at a greater distance therefrom to an inner end position at a shorter distance therefrom while forcibly driving in the wedge members (17, 23) between the lid flange (48) and the can flange (49), and means (21) for releasably holding the wedge members (17, 23) in their initial positions during at least an initial portion of the movement of the holder-up (24) from its outer end position to its inner end position.
