Abstract
A liquid dispensing device including a sealing component which can take up a liquid release position and a liquid blocking position. The sealing component includes an elastomer part and a rigid part, these parts being fastened to each other when moving.
Claims14
A device for dispensing liquid in drop form, characterized in that the device comprises a nozzle comprising:
- a sealing component which can take up a liquid release position and a liquid blocking position, and
- a pressing element for pressing on the sealing component;
- wherein the sealing component comprises an elastomer part and a rigid part, the elastomer part, in the liquid blocking position, cooperating with said pressing element to provide a seal, the elastomer part and the rigid part being fastened to each other such that when the elastomer part of the sealing component moves the rigid part moves together with the elastomer part,
- wherein exertion of pressure of the liquid on the sealing component causes the sealing component to move from the liquid blocking position to the liquid release position to allow liquid to be dispensed;
- wherein in the liquid release position, the seal between the pressing element and the sealing component is broken;
- and
- wherein the sealing component comprises parts for forming liquid drops, the parts for forming drops having the shape of a cone widening towards a distal end of the device.

- a pressing element for pressing on the sealing component;
- wherein the sealing component comprises an elastomer part and a rigid part, the elastomer part, in the liquid blocking position, cooperating with said pressing element to provide a seal, the elastomer part and the rigid part being fastened to each other, at least when moving,
- wherein exertion of pressure of the liquid on the sealing component causes the sealing component to move from the liquid blocking position to the liquid release position to allow liquid to be dispensed;
- and
- wherein the sealing component comprises parts for forming liquid drops, the parts for forming drops having the shape of a cone widening towards a distal end of the device;
- the device further comprising a return element, exerting a return force on the elastomer part so that the sealing component takes up the liquid blocking position, the return element resting against or being fixed to the rigid part of the sealing device.

A device for dispensing liquid in drop form, characterized in that the device comprises a nozzle comprising:
- a sealing component comprising an elastomer part and a rigid part, said sealing component moveable between a liquid release position and a liquid blocking position, and the elastomer part and the rigid part being fastened to each other such that when the elastomer part of the sealing component moves the rigid part moves together with the elastomer part;
- and
- a core having a side surface and a distal end surface;
- wherein, in the liquid blocking position, a surface of the elastomer part of the sealing component cooperates with the distal end surface of said core to provide an annular seal;
- wherein in the liquid release position, the seal between the pressing element and the sealing component is broken;
- and
- wherein the sealing component comprises parts for forming liquid drops, the parts for forming drops having the shape of a cone widening towards a distal end of the device.
