Abstract (en)
[origin: WO2020225223A1] The prior art discloses a discharge head (10) for a liquid dispenser (100) having a base (20) and a push actuator (50), which can be pressed down relative to the base (20). Said discharge head (10) has a pump device (12), which comprises a malleable pump chamber component (80), which is open on both sides, is fastened to the base (20) and to the push actuator (50) and encloses a pump chamber (13) having variable volume, and which pump device has an inlet valve (14) and an outlet valve (16). The discharge head (10) has at least one ventilation opening (28) and a ventilation valve (18), wherein the ventilation valve (18) on the base (20) has a peripheral valve web (42), which is raised via a surrounding radially extended cover wall (24) of the base and the inside of which forms a peripheral valve surface. In order to ensure a reproducible behavior of the ventilation valve, according to the invention, a reinforcement structure (26) is provided on the surrounding cover wall (24) on the outside, on a top side of the cover wall (24), preferably in the form of a peripheral reinforcement web, and/or the peripheral valve web (42) is designed as a part of a sleeve-like structure, which forms the peripheral valve web (42) above the cover wall (24) and which continues under the cover surface in a peripheral wall portion (46) flush to the valve web (42).
