Abstract: A method is provided for the two-stage pressurizing of a product in which a propellant gas may be immediately generated for use as a high-pressure propellant after the sealing of the container. A first reactant and the flowable or sprayable product which is desired to be dispensed is placed into the container until the container is substantially full. The container is then sealed. A second reactant, which may be dissolved in a further amount of product, is introduced in liquid form into the sealed container through a dispensing valve, another valve, or a sealable plug. The first and second reactants react to generate the propellant, which is then contained or dissolved with the product in the container until needed. As product is expelled, the propellant evolves out of the product to exert expulsive pressure. Thus, the invention involves the process of charging during the filling of product and allows the product to be dispensed promptly and continuously thereafter.

The beam spring will allow air to enter the bottle upon the application of negative pressure within the bottle. An automated mechanism is provided for cutting and grasping (e.g., utilizing a vacuum mandrel) a beam spring comprising a predetermined length of a band of flexible material.

Abstract: In the "undercap" method of, and closure cap crimper-propellant fill head apparatus for, introducing a charge of volatile propellant in its liquid state into an aerosol container containing product to be dispensed, a significant residual amount of the propellant charge remains in the crimper-propellant fill head bell after the closure cap has been secured in place to seal the container. Not all crimper-propellant head machines are equipped with systems for reclaiming residual propellant, and even when so equipped, it is not always practical to reclaim residual propellant since certain products to be dispensed will foul the reclamation equipment. According to this invention a compressed purge gas is injected into the crimper-propellant fill head bell to purge a substantial portion of the residual propellant into the container before it is sealed by crimping its closure cap on the container mouth.

Abstract: Carbonated and non-carbonated beverages are selectively dispensed under the driving force of a one time charge of pressurized inert gas inserted into the headspace of the beverage container at the time of bottling/canning.

A cap valve seals the container and includes an elastomeric check valve preventing escape of gas while permitting the siphon tube to be inserted into the container. A throttling and diffusing valve controls outflow from the siphon tube to ambient and prevents fracturing of gas from the beverage liquid to minimize foaming/frothing.

Abstract: A disc for mounting a valve onto a spray can which is capable of engaging a standard-sized protective cap such that the cap fills all the space between the disc and the top of the spray can regardless of variations in the thickness of the disc or the seal.
