Cap, for an aerosol/spray can, has a folded acoustic seal at the button as an elastic link between it and the cap

摘要

The cap (7), for an aerosol or spray can, has a button (6) with an elastic link (49) between it and the cap to form a folded acoustic seal. The seal can be a bellows structure or a single fold around the button, to give a hermetic seal between the cap and button, with a thicker section (30) away from the cap zone (29) with the spray outlet opening (3).
