Abstract (en)

A manually operable fluid dispensing pump (10) for attachment to a container (14) for a fluid to be dispensed, comprising an open flexible tubular bladder (20), a housing (16) which includes a cavity (11) intended to contain the tubular bladder, and a trigger (18) connected to the housing (16), such that it will depress the bladder (20). The bladder has a downstream end (20b) provided with a one-way outlet valve comprising a cylinder with a cross-section smaller than the cross-section of the bladder, which interacts with post (50) on assembly with the nozzle (22), an upstream end (20a) open to permit fluid to flow into the bladder under control of a flap-valve formed by the bladder side wall. The upstream flap-valve permits the flow of fluid from the container (14) via a channel (21, 28) to the pump when the bladder expands to regain its natural profile after depression. Venting means (45) are incorporated between container (14) and cavity (19), and the trigger (18) operates on the bladder (20) by means of a skid plate (30) having a raised profile (30A).
