Abstract
Proposed are an outlet valve and a dispensing device with an outlet valve for a cosmetic liquid. The outlet valve has a flatly resting valve element with an outlet formed therein. The outlet valve is able to open through the elastic deformation of the valve element.
Claims44
Valve for a liquid comprising:
- a valve element that is elastically deformable in a deformation area for opening of the valve;
- a retention section associated with the valve element;
- and
- an outlet,
- wherein the valve element is non-detachably connected to the retention section around the deformation area or is held in a sealing manner against or on the retention section,
- wherein the valve element rests flatly on the retention section and covers an outlet channel,
- wherein the outlet is formed through the valve element, and
- wherein the valve element is injected or glued directly against the retention section and is connected to the retention section.

Dispensing device for a cosmetic liquid, wherein the dispensing device has or forms a dispensing head, wherein the dispensing head has an outlet valve for the liquid or a product formed from it,
- wherein
- the outlet valve is installed as a prefabricated assembly and comprises:
- a valve element that is elastically deformable in a deformation area for opening of the valve;
- a retention section associated with the valve element;
- and
- an outlet,
- wherein the valve element is non-detachably connected to the retention section around the deformation area or is held in a sealing manner against or on the retention section,
- wherein the valve element rests flatly on the retention section and covers an outlet channel,
- wherein the outlet is formed through the valve element, and
- wherein the outlet of the valve element is covered by the retention section in the closed state of the valve.
