Abstract: An improved strength machine is at least partly distinguished by the following features: having a housing (20), a housing frame (141), an inner supporting structure (145) and/or an inner frame (145, 150), having a rotatable flywheel weight (13) mounted in the housing (20), on the housing frame (141), on the inner supporting structure (145) or on the inner frame (145, 150), the flywheel weight is fitted on a shaft (12) or is seated on a shaft (12), having a flexible pulling element (3), the flexible pulling element (3) is attached to the shaft (12) or a reel (95) which is mounted on a freewheel bearing (94), which is pretensioned by means of a spring arrangement (96) in the wind-up direction of the pulling element (3).

Abstract: A tube having a cylindrical tube body, an end wall closing off one end of the body, and a dispensing nipple disposed on the end wall coaxially to the axis of the tube body. The end wall has at least one portion weakened by reduced wall thickness or reduced material hardness so that two parts of the end wall may be collapsed onto one another for completely emptying the tube. For emptying a tube, an apparatus is provided which has a trough-shaped casing for accommodating the tube and a squeezing body movable within the casing. The casing surrounds the tube through an angle of more than 180° and has a longitudinal slot for manually moving the squeezing body.
