An application device for applying a dispensable material is disclosed having a closed state and an open state, the application device comprising an elastic part made of an elastic material and having a through channel being configured for engaging a cavity of a receptacle, further comprising a holder supporting a dispensing means fluidly connected with the through channel. A pinch seal is used for sealing the through channel when being in the closed state. Long-term storage is made possible, since leakage of the pinch seal is prevented by a cap effecting the pinch seal which is partially fitted into a collar.
