DESCRIPTION:
BRIEF SUMMARY
BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention relates to a portable dispensing assembly for dispensing fluid substances such as but not limited to foodstuffs such as ice-cream. More particularly, the invention relates to a dispensing assembly able to be worn as a "back-pack" by an operator so that the contents may be dispensed in remote locations.
The invention may also be used to dispense substances other than foodstuffs such as poisons, water, chemicals and the like. Although the invention is suitable for dispensing substances other than foodstuffs, it will be described principally with reference to its application for dispensing foodstuffs and particularly ice-cream.
2. Description of Related Art
Ice-cream is usually dispensed for purchase from an open, externally-cooled container, by the use of a scoop or by extension from a power-operated device, via a faucet or spigot. This form of dispensing means that the ice-cream storage containers must remain in one place as they are too heavy to be portable and cannot be separated from their source of refrigeration.
SUMMARY OF THE INVENTION
The present invention aims to overcome the several problems inherent in the above-mentioned systems by providing according to one embodiment a dispensing device for fluid substances and the like which is portable and includes self contained cooling means. Thus, the present invention, in one form, comprises a dispensing assembly including a vessel for the said substance; a floating piston or diaphragm arranged for movement in the vessel; a source of propellant gas for moving the piston or diaphragm within the vessel; a discharge line through which the substance is able to pass and which terminates in a dispensing nozzle in communication with a discharge valve; and a regulator valve for controlling the flow of propellant gas from the source to the rear face of the piston.
In a preferred embodiment of the invention, the above-described dispensing assembly is incorporated into a "back-pack" able to be carried by an operator so that a paste like substance such as ice-cream or the like may be dispensed and sold at remote locations. Such a back-pack form may also include cooling means such as a receptacle for ice or "dry ice" and a cone holder with an associated cone-feed mechanism.
In one broad form the present invention comprises; substances, the assembly comprising; flow, wherein the propellant energises the contents of the vessel, upon actuation of the discharge valve; and mounting on the back of an operator of the dispensing assembly.
In another broad form the present invention comprises; assembly on the back of an operator; the dispensing assembly comprising; communication with both a container for storing and discharging a propellant into said vessel to energise said contents and a discharge assembly through which the contents of the vessel are discharged via a discharge valve.
In its broadest form the present invention comprises; dispensing assembly comprising; is in communication with a propellent and a discharge assembly, pressure into said vessel to energise said contents, wherein the energised contents are discharged from the assembly via the dispensing valve assembly.
According to a preferred embodiment, the dispensing assembly is contained within a housing forming a back pack which fits to the back of an operator via shoulder saddles and a waist harness.
