Abstract
An aerosol type container wherein a separate product bag of plastics material is provided. The bag is of a larger size than the opening in which the valve cup is seated and thus must be gathered or pleated to pass through that reduced diameter opening. The initially gathered or pleated bag material is compressively engaged between the top curl defining the opening and the valve cup and is heated to a molding and bonding temperature so that a molded ring conforming to the adjacent portions of the top curl and the valve seat is formed, this part eliminating the usual need for a compound or other sealant between the valve cup and the top curl.
