Abstract
A dispenser for apportioned dispensing of material, particularly pasty masses. The dispenser has a piston which travels within the dispenser storage chamber toward a mouthpiece dependent on actuating steps. A slide is displaceable toward the mouthpiece by an actuating handle. The slide is guided in sealed fashion by a lip. The slide includes a wing which, upon an actuating stroke, comes in sealing fashion against the wall of an ejection channel and upon a return stroke lifts away from the wall of the ejection channel. The wing is flat in shape, and forms one resiliently movable leg of the slide. The slide is V shaped, with the V tip facing the piston, and extending into the material.

In a dispenser for apportioned dispensing of material, including a dispenser housing, a mouthpiece, a storage chamber for the material, a piston arranged to travel within the storage chamber in a direction toward the mouthpiece in dependency on dispensing actuation steps, an actuating handle, a slide displaceable by said handle toward the mouthpiece, lip means arranged for sealingly guiding the slide to the housing, an ejection channel connected to the mouthpiece, and a wing arranged to come in sliding contact against a wall of said ejection channel during an actuating stroke and to move away from the wall of the ejection channel during a return stroke, the improvement wherein:
- said wing is flat,
- said slide is V-shaped,
- said wing forms one resiliently moveable leg of said V-shaped slide,
- the vertex of said V-shaped slide points toward said piston, and
- said slide extends into said material.
