Abstract
A discharge head for a liquid dispenser for discharging cosmetic products which has a base to be secured to a liquid storage. The base has a coupling device in the form of a thread or a latching coupling device, for coupling to the liquid storage. The discharge head has a sponge carrier with a sponge receptacle in which a sponge is arranged. The sponge carrier is movable in a translationally guided manner with respect to the base and has a hollow connector inside which a liquid channel is provided that connects the liquid storage to the sponge receptacle. This liquid channel is provided with an outlet valve, which is opened by moving the sponge carrier in the direction of the base, such that liquid can flow freely out of the liquid storage into the sponge receptacle.
Claims18
A discharge head for a liquid dispenser for discharging cosmetic products, comprising:
- a base to be secured to a liquid storage means;
- the base having a coupling device for coupling to the liquid storage means;
- a sponge carrier with a sponge receptacle in which a sponge is arranged;
- the sponge carrier is being movable in a translationally guided manner with respect to the base;
- the sponge carrier having a hollow connector inside which a liquid channel is provided that connects the liquid storage means to the sponge receptacle;
- and
- an outlet valve, which is assigned to the liquid channel and which can be opened by moving the sponge carrier in the direction of the base, such that liquid can flow freely out of the liquid storage means into the sponge receptacle.
A discharge head for a liquid dispenser for discharging cosmetic products, comprising:
- a base to be secured to a liquid storage means;
- the base having a coupling device;
- and
- an applicator portion which is movable in a translationally guided manner with respect to the base;
- the applicator portion having a hollow connector inside which a liquid channel is provided by way of which the applicator portion can be fed with liquid from the liquid storage means;
- at least one outlet valve, which is assigned to the liquid channel and which interrupts a supply of liquid to the applicator portion;
- and
- a one-piece sealing component on the coupling device, said sealing component having a peripheral bottle-sealing portion by which a contact region between the base and the liquid storage means is sealed off from an environment;
- and
- the sealing component has an inner sealing portion which interacts with the hollow connector in such a way that:
- a sliding sealing face on the inner sealing portion interacts with an outer face of the hollow connector in such a way that, during translational movement of the hollow connector with respect to the inner sealing portion, no liquid can flow between the sliding sealing face and the outer face of the hollow connector, and/or
- a valve body face provided on the hollow connector bears, in an end position of the applicator portion, on a valve sealing face of the inner sealing portion in such a way that the liquid channel is thereby interrupted.
