摘要
A thermoplastic bottle has a crimped valve cup and a method of manufacturing a thermoplastic bottle includes crimping a valve cup to such a bottle. The thermoplastic bottle and valve cup may be used in a system to dispense aerosol products. At least one protrusion extends from a flange of the bottle to which the valve cup is crimped. Prior to being crimped to the bottle, the valve cup is set to the bottle with an interference fit between a crimping portion of the valve cup and the protrusion. The interference fit prevents shifting of the valve cup from its set position on the bottle prior before the valve cup is crimped.
