Embodiment Construction

[0046] figure 1 A liquid dispenser 100 is shown, which is used for dispensing pharmaceutical or cosmetic liquids, for example for dispensing body wash. The liquid dispenser 100 has a liquid reservoir 110 and a discharge head 10 which is fastened to the bottle neck or reservoir socket of the liquid reservoir 110 by means of a thread or another connection technique.

[0047] The discharge head 10 has a base 20 and an actuation pusher 50 which is depressible relative to the base 20 in the direction of the actuation direction 2 . An outlet opening 52 is provided on the actuation pusher. By pressing the actuating button 50 , the pump device 12 arranged in the discharge head 10 is actuated, which pumps liquid from the liquid reservoir 110 to the discharge opening 52 .

[0048] exist figure 2 The discharge head 10 is shown in more detail in . refer to the figure 2 as well as image 3 The exploded view of the explains the components in detail.

Abstract

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).

Description

technical field [0001] The invention relates to a dispensing head for a liquid dispenser for dispensing pharmaceutical or cosmetic liquids and to a liquid dispenser provided with such a dispensing head. Background technique [0002] This type of discharge head has a deformable pump chamber member, which is arranged between the base and the actuating pusher, so that its internal volume cooperates with the inlet valve and the outlet valve to form a pump chamber, the pump The contents of the chamber can be brought out by depressing the actuating pusher. A discharge head of this type can be constructed in a particularly simple design from only three components, since the inlet and outlet valves and, if applicable, the ventilation valve can be arranged in one piece by means of valves arranged in one piece on the pump chamber components. The lip or body is formed with the base or mating wall of the actuating pusher. [0003] A distributor of this type is known from EP 3427840 A1...
