1. A cosmetic dispenser in the form of a pen for discharging a cosmetic medium, said cosmetic dispenser comprising:
a housing elongated along a main direction of extent and having an end face including a discharge opening; a liquid reservoir disposed within an interior of said housing and filled with a liquid cosmetic; a pumping device disposed within said interior of said housing, said pumping device including a pump chamber connected to said liquid reservoir on an inlet side of said pump chamber and to said discharge opening on an outlet side of said pump chamber; a flexible wall disposed in circumferentially surrounding relation with said pump chamber, said flexible wall having openings only at said inlet and outlet sides of said pump chamber, said flexible wall having an exterior surface disposed on a lateral surface of said housing and forming an actuating portion of said pumping device; and a valve disposed between said discharge opening and said pump chamber, said valve including two valve lips formed as one-piece with said flexible wall, said valve lips having respective surfaces disposed in opposed relation and in direct contact with one another to define a closed position of said valve, said valve lips being movable away from one another and out of contact with one another to define an open position of said valve which permits communication between said pump chamber and said discharge opening to dispense a predetermined amount of liquid cosmetic through said discharge opening; said housing including first and second rigid housing components disposed, along the main direction of extent, on respective opposite sides of said actuating portion, and a third rigid housing component interconnecting said first and second rigid housing components to one another, said third rigid housing component including a counterforce surface disposed, in a circumferential direction of said housing, substantially opposite said actuating portion to permit application of a force to said actuating portion with one finger and application of a counterforce to said counterforce surface with another finger, said third rigid housing component being disposed in circumferentially surrounding relation with said flexible wall and defining an opening through which said actuating portion is accessible, said flexible wall and said third rigid housing component being formed as an integral two-component injection-molded part.
