Abstract (en)
[origin: EP0738543A2] The pump issues pastes from a paste container (6). It has bellows (13) connecting an upper casing part (4) to a lower one (3). The casing parts fit telescopically. There is a paste channel (47) inside an annular wall. The upper casing part contains a second hollow body (23) forming a paste storage space with the paste channel. This contains a spring-elastic membrane wall (42) which has a closer (43) in the form of a plug. The second hollow body has an attachment (36) on an endface wall (35) at a right angle to the axis (31) of the outlet aperture (30), with which it is concentric. The attachment has a ventilation and air outlet boring (38).
