摘要

The cap has a button operating through a spraying channel against a stem to move the stem and to open a valve. The product in a container exits via the stem and a product delivery opening. An acoustic seal (49) is provided between the button and the cap, where the seal is a circular seal flank. A circulating edge of the button touches down during pressing down of the button on the seal to close a gap between the edge and the seal.
