Abstract

A connector for manually connecting a dispensable fluid to a fluid dispensing includes: a cleaning fluid inlet; a dispensable fluid inlet and an outlet, wherein the cleaning fluid inlet is in fluid communication with the outlet via a cleaning fluid flow path, and wherein the dispensable fluid inlet is in fluid communication with the outlet via a dispensable fluid flow path. A fluid dispensing apparatus, such as a coffee dispensing apparatus, may include the connector.

Claims (21)

1 . A connector for manually connecting a dispensable fluid to a fluid dispensing apparatus, the connector comprising:

a main body comprising a cleaning fluid inlet and an outlet;

a dispensable fluid connector which is detachably attachable to the main body and comprising a dispensable fluid inlet; and,

wherein the cleaning fluid inlet is in fluid communication with the outlet via a cleaning fluid flow path, and wherein the dispensable fluid inlet is in fluid communication with the outlet via a dispensable fluid flow path;

wherein the outlet is in fluid communication with the cleaning fluid inlet to provide a cleaning fluid flow path through the main body and/or the dispensable fluid connector; and

wherein the cleaning fluid flow path comprises a first cleaning fluid flow path through the main body, and a second cleaning fluid flow path through the dispensable fluid connector and the dispensable fluid connector is configurable to select either the first or second cleaning fluid flow paths.

2 . The connector of claim 1 , wherein the cleaning fluid flow path and dispensable fluid flow path are connected at a convergence upstream of the outlet.

3 . The connector of claim 1 , further comprising a one-way valve in the dispensable fluid flow path and/or the cleaning fluid flow path.

4 . The connector of claim 3 , wherein the one-way valve is a duck bill valve.

5 . The connector of claim 1 , wherein the main body comprises a first body portion and a second body portion configured to rotate relative to each other between a first configuration in which the cleaning fluid inlet is connected to the outlet via the first cleaning fluid flow path, and a second configuration in which the cleaning fluid inlet is connected to the outlet via the second cleaning fluid flow path.

6 . The connector of claim 5 , wherein the dispensable fluid connector is rotatable relative to the main body, wherein rotation of the dispensable fluid connector relatively rotates the first and second body portions between first and second positions to provide the first and second configurations.

7 . The connector of claim 1 , wherein the dispensable fluid connector and the main body are connected by an inter-engagement of a projection and a channel to provide a bayonet fitting, wherein the main body comprises the channel and the dispensable fluid connector comprises the projection which is received by the channel.

8 . The connector of claim 1 , wherein the dispensable fluid connector comprises a tube for insertion into a container or wherein the dispensable fluid connector is connectable to a container.

9 . The connector of claim 1 , wherein the dispensable fluid connector comprises an external surface, wherein the external surface comprises a gripping feature.

10 . A fluid dispensing apparatus comprising the connector of claim 1 .

11 . The apparatus of claim 10 , wherein the apparatus is a coffee dispensing machine and the dispensable fluid is milk.

12 . The apparatus of claim 10 , wherein the connector forms part of a cleaning fluid circuit.

13 . The apparatus of claim 12 , wherein the cleaning fluid circuit comprises one or more of a cleaning agent dispenser, a water supply, a water heater, a drain, a fluid dispensing nozzle for dispensing fluid from the apparatus.

14 . The apparatus of claim 10 , wherein the connector is fixedly attached to the apparatus.

15 . The apparatus of claim 10 , wherein the dispensable fluid is milk and the apparatus further comprises a source of milk attached to the connector.

16 . The connector of claim 1 , wherein the dispensable fluid connector is disposable and optionally made from a biodegradable material.
