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.

Abstract: A nib for a calligraphic dip pen includes a first inner plate with a first inner plate point end, a second inner plate with a second inner plate point end, and a core with a core top end. The first inner plate and said second inner plate are affixed to the core top end. The first inner plate and the second inner plate are bent toward an axial line of the core such that the first inner plate point end and the second inner plate point end are in contact. The nib for a calligraphic dip pen further includes a spacer plate positioned against either the first inner plate or the second inner plate. The spacer plate includes a spacer plate point end positioned in contact with both the first inner plate and the second inner plate.

Abstract: Devices have a flexible housing with an inside chamber having a closed and open end. A first chemiluminescent fluid is disposed in a breakable container in the chamber, and a second chemiluminescent fluid is in the chamber. A tip assembly is attached to the housing and includes a nib movably disposed in the body, and a filter element may be positioned within the body to prevent passage of broken particles from the container to the nib tip. A resilient element is used to impose an outward biasing force on the nib. A porous material is disposed over an outer surface of the nib tip and securely held in place. The device is activated for use by bending the housing to break the container causing the first and second chemiluminescent fluids to mix and react, providing a chemiluminescent solution that flows to the tip assembly for dispensing onto a desired surface.
