Abstract
The invention relates to a receptacle with a plunger, which is displaceably arranged therein. The plunger comprises a plunger body with a flat face, whereby at least two encircling sealing lips are shaped onto the plunger body. Each sealing lip has slot-shaped notches at at least one location that, as soon as the plunger is inserted into the receptacle, permit a gas exchange between the inside of the receptacle and the outside atmosphere. The invention also relates to the use of the receptacle and of the plunger for storing and discharging, in particular, dental materials.
