System for dispensing liquid from inverted container

A positive pressure valve assembly for use with a container having a main body for storing a supply of a liquid to be dispensed and a dispensing opening, the positive pressure valve assembly comprising:

• an engagement collar sized to be securely attached to the dispensing opening of the container;
• a dispensing tube extending from the engagement collar and including a liquid passageway;
• a flow restrictor positioned to selectively open and close the dispensing tube to control the flow of the liquid out of the dispensing tube;
• a one-way valve positioned in the engagement collar to allow air flow into an open interior of the main body as the liquid is dispensed to maintain a pressure within the open interior;
• an air supply member having an air flow passageway including an air inlet is configured to receive a supply of air and the air outlet is positioned to deliver the supply of air to the one-way valve;
• and
• a valve base coupled to the air supply member, wherein the flow restrictor is pivotably mounted between the valve base and the air supply member.

A liquid dispenser for dispensing liquid from a container for the liquid that includes a main body and a dispensing opening, comprising:

• a cabinet sized to receive the container in an inverted position such that the liquid can flow out of the dispensing opening under the influence of gravity;
• a positive pressure valve assembly sized to be received and retained on the dispensing opening of the container, the positive pressure valve assembly comprising:
• an engagement collar sized to be securely attached to the dispensing opening of the container;
• a dispensing tube extending from the engagement collar and including a liquid passageway;
• a flow restrictor positioned to selectively open and close the dispensing tube to control the flow of the liquid out of the dispensing tube;
• a one-way valve positioned in the engagement collar to allow air flow into an open interior of the main body as the liquid is dispensed to maintain a pressure within the open interior;
• and
• an air supply member having an air flow passageway including an air inlet
• and an air outlet in communication with the one-way valve, wherein the air supply member includes a center opening, wherein the dispensing tube extends through the center opening when the positive pressure valve assembly is mounted to the container;
• an air producer operable to direct an air flow into the air inlet of the air supply member;
• and
• a controller operable to activate the air producer and to control the movement of the flow restrictor to control the discharge of the liquid from the dispensing tube of the positive pressure valve assembly.

A liquid dispenser for dispensing liquid directly from a container for the liquid that includes a main body and a dispensing opening, comprising:

• a cabinet sized to receive the container in an inverted position such that the liquid can flow out of the dispensing opening under the influence of gravity;
• a positive pressure valve assembly sized to be received and retained on the dispensing opening of the container, the valve assembly comprising:
• an engagement collar sized to be securely attached to the dispensing opening of the container;
• a dispensing tube extending from the engagement collar and including a liquid passageway;
• a flow restrictor positioned to selectively open and close the dispensing tube to control the flow of the liquid out of the dispensing tube;
• and
• an air supply member having an air flow passageway in communication with the dispensing opening of the container, wherein the air supply member includes a center opening, wherein the dispensing tube extends through the center opening when the positive pressure valve assembly is mounted to the container;
• wherein the flow restrictor is operable to control the discharge of the liquid and the air supply member provides air flow into the main body of the container as the liquid is dispensed.
