Abstract
This invention provides a new, simple, inexpensive and expedient means of attaching an expandible elastomeric pressure unit within an existing vessel using a readily available valve for dispensing fluid products contained therein. The present invention by using elastomeric pressure units for the dispensing of fluid products under pressure no longer requires the use of propellent gas therewith since the dispensing energy is contained in the elastomeric material of the unit itself, the dispensing p.s.i. being controllable by varying the thickness of the walls of the said pressure unit and the composition and make-up thereof. The present invention also teaches various bonding techniques for efficiently attaching the pressure unit to the valve member in most cases where the container is filled through the valve itself and also for attaching the pressure unit to the vessel means in those cases wherein the container is filled around the valve but before the said valve is sealed into place.
