Abstract

A dispensing system (2) for a grease degrading enzyme fluid includes a container (20) for fluid to be dispensed, a fluid flow tube (30) for allowing fluid to flow from the container to an outlet (36), and an electrically operated valve (32) for controlling the flow of fluid through the tube. The system also includes a control circuit (42) for actuating the valve (32) to dispense fluid at predetermined intervals and a battery (44) for supplying power to the valve and the control circuit.

Claims

1. A dispensing system including a container for a fluid to be dispensed, a fluid flow tube for allowing fluid to flow from the container to an outlet, an electrically operated valve for controlling the flow of fluid through the tube, a control circuit for actuating the valve to dispense fluid at predetermined intervals, a battery for supplying power to the valve and the control circuit, and a housing that encloses the container, the valve, the control circuit and the battery, in which the container is supported within the housing by a resilient spring element so that in use the vertical position of the container within the housing varies according to the weight of fluid in the container, and wherein the container includes an indicator for indicating the quantity of fluid in the container according to its vertical position within the housing.

2. A dispensing system according to claim 1, in which the housing includes a window for viewing the indicator.

3. dispensing system according to claim 1, in which the container includes a flexible bag inside a substantially rigid outer box.

4. A dispensing system according to claim 1, in which the container includes a connection fitting for connection to the fluid flow tube.

5. A dispensing system according to claim 4, in which the connection fitting includes a non-drip valve.

8. A dispensing system according to claim 1, in which the fluid includes a grease degrading enzyme.

9. A dispensing system according to claim 1, wherein the dispensing system is constructed and arranged to be mounted on a wall.

10. A dispensing system according to claim 1, wherein the valve for controlling the flow of fluid is an electrically operated latching valve.
