Abstract
A dispensing system for dispensing decorating materials such as frosting incorporates a dispensing tube having the material to be dispensed and a water-operated piston therein. Application of water under pressure to the dispensing tube results in the dispensing of the material through a decorating tip. The water pressure applied to the dispensing tube is controlled and regulated through the utilization of a control valve assembly having a flow stop valve and an on/off valve. Water applied to the control valve assembly is pressure regulated and filtered.
Claims14
A dispensing system for decorating or filling edible products and for connection to a source of water under pressure comprising:
- (a) a water pressure regulator connected to receive water from said source and deliver water at a regulated reduced pressure;
- (b) an on/off water valve actuatable by an operator connected to said water pressure regulator;
- (c) flexible tube connected at one end thereof to said water valve to receive water under pressure therefrom;
- (d) a dispensing tube connected to an opposite end of said flexible tube to receive water under pressure therefrom when said on/off water valve is on;
- (e) said dispensing tube having:
- i. a quick disconnect connector at one end thereof for connection to said flexible tube;
- ii. a hollow cylindrical body;
- iii. a piston in said body forming a first chamber on one side thereof for containing decorating material to be dispensed and a second chamber on another side thereof in communication with said flexible tube to receive water under pressure;
- iv. means defining an exit opening in said first chamber for permitting
- the flow of decorating material therefrom;
- whereby, operation of said on/off valve by the operator causes water under pressure to be admitted to said second chamber to force said piston against said decorating material in said first chamber resulting in the dispensing of said material through said exit opening onto or into an edible product.

A dispensing system for decorating or filling edible products and for connection to a source of water under pressure comprising:
- (a) an on/off water valve actuatable by an operator connected to a source of water;
- (b) a flow stop valve having:
- i. an inlet connected to receive water under pressure from said on/off valve when the latter is on;
- ii. an outlet;
- iii. a variable volume valve body between said inlet and said outlet;
- iv. a piston in contact with a rolling diaphragm, said piston connected to said diaphragm to force said diaphragm into and out of said variable volume in said valve body to increase and decrease said volume and temporarily decrease and increase the pressure respectively of said water;
- (c) a flexible tube connected at one end thereof to the outlet of said flow stop valve;
- (d) a dispensing tube connected to an opposite end of said flexible tube to receive water under pressure therefrom when said on/off water valve is on;
- (e) said dispensing tube having:
- i. a quick disconnect connector at one end thereof for connection to said flexible tube;
- ii. a hollow cylindrical body;
- iii. a piston in said body forming a first chamber on one side thereof for containing decorating material to be dispensed and a second chamber on another side thereof in communication with said flexible tube to receive water under pressure;
