摘要:
A piston pump dispenser for dispensing liquids such as soap, comprising a piston chamber (2) in fluid communication with an inlet (2a) and an outlet (1b). A piston (1) is arranged for a reciprocating movement between a depressed position and a retracted position within said piston chamber (2). A one-way valve assembly (3) arranged for preventing fluid flow from said outlet (1b) to said piston chamber (2). Characteristically, said inlet (2a) is arranged on the piston chamber (2) such that, when the piston (1) is displaced a certain distance from said retracted position towards said depressed position, the piston (1) closes the fluid communication between the inlet (2a) and the piston chamber (2), thus preventing liquid from flowing from the piston chamber (2) to the inlet (2a) when the volume of the piston chamber (2) is decreased.

The present invention concerns a detachable brake element (1) for a paper dispenser. Said brake element comprises a braking surface (1a) and attachment means (1d). Characteristically said attachment means are suitable for detachably attaching the brake element (1) to a paper dispenser so as to apply a braking force with said braking surface (1a) on an end surface of a paper roll supported by the paper dispenser. A paper dispenser capable of receiving, and a paper dispenser comprising such a brake element (1) are also concerned.

The dispenser 1 comprises a cross contamination protection cover 4 surrounding the tail 3, forming a narrow opening 5 and providing limited access for a user to pull the tail 3.
摘要:
A spring system operatively connected to a dispenser drum (1) of a roll towel dispenser, being rotatable in a housing (2) and provided with a longitudinally extending knife (3) reciprocating between an inner and an outer position during each revolution of the dispenser drum (1) guided by a cam track (4) positioned in one or both end walls (2a) of the housing (2).The spring system comprises a short return spring (5) and a long positioning spring (6) connected eccentrically to one en d of the dispenser drum (1), at a common connection point (7), the other end of said springs (5, 6) being connected to a common connection point (8) near the back of the housing (2), whereby the positioning spring (6) is further led around a guide pin (9) positioned at such a position near the front of the housing (2), that the two springs (5, 6) form a triangle in each position during a revolution of the dispenser drum (1).
