Dispenser for proportioned emission of pasty substances

摘要: The dispenser for pasty substances (M), e.g. mustard or the like, has a housing (1), on upper edge (3') of which top (10) is seated support pumping device (2), and in (1) piston (5) provided travels stepwise downwards direction bottom (8) penetrated by stationary riser tube (6) reaches down to bottom, end connection with discharge spout (16), adjoining there an actuation surface (17) device, during return sucked downwards. To achieve shape simple manufacture optimum use, it proposed that (6), open at below inlet valve (V1) pump space (15) elastically reduced displacement initial basic position (Figure 7) clearance such way volume remaining between corresponds approximately inside (15).
