Abstract

A dispensing system for dispensing an associated substantially viscous product includes a dispensing system housing and a first container. The first container is disposed within the dispensing system housing and has an elastically deformable wall defining a changeable volume for containing the associated product. The elastically deformable wall is expandable between an unexpanded state and an expanded state. The first container includes an outlet through which the associated product is expelled. Potential energy stored in the deformable wall in the expanded state is operable to expel the associated product from the first container through the outlet. The dispensing system includes a selectively engage-able valve operatively fluidly connected to the outlet for controlling the expulsion of a predetermined amount of the associated product from the outlet. An actuator is operatively coupled to the valve to selectively engage the valve.

First claim

What is claimed is:

1. A dispensing system for dispensing an associated substantially viscous product, the dispensing system comprising:
a dispensing system housing;
a first container disposed within the dispensing system housing and having an elastically deformable wall defining a changeable volume for containing the associated product, the elastically deformable wall expandable between an unexpanded state and an expanded state, the first container comprising an outlet through which the associated product is expelled, wherein potential energy stored in the deformable wall in the expanded state is operable to expel the associated product from the first container through the outlet;
a selectively engage-able valve operatively fluidly connected to the outlet for controlling the expulsion of a predetermined amount of the associated product from the outlet; and
an actuator operatively coupled to the valve to selectively engage the valve;
wherein a first chamber is defined between the first container and a second container that envelopes the first container and is disposed within the dispensing system housing, and wherein the second container defines an opening at which a pump is attached to the second container for introduction of a pressurization material into the first chamber to increase a pressure applied to the first container.

2. The dispensing system of claim 1 , wherein the selectively engage-able valve defines a fixed volumetric region from which the predetermined amount of associated product is expelled and wherein the selectively engage-able valve comprises a valve inlet and a valve outlet.

3. The dispensing system of claim 2 , wherein the valve comprises a displacement member moveable between a first and a second position.

4. The dispensing system of claim 3 , wherein movement of the displacement member to the first position allows the associated product to flow into the fixed volumetric region.

5. The dispensing system of claim 4 , wherein movement of the displacement member to the second position allows the associated product to flow out through the valve outlet.

6. A dispensing system for dispensing an associated substantially viscous product, the dispensing system comprising:
a dispensing system housing;
a first container supported by the dispensing system housing, the first container having a deformable body defining a changeable volume for containing the associated product, the first container comprising an outlet through which the associated product is expelled from, wherein the deformable body is expandable between an unexpanded state and an expanded state;
a second container supported by the dispensing system housing, the second container being pressurize-able, wherein the first container is disposed at least partially within the second container; and
a pump having a pump inlet and a pump outlet, wherein the pump inlet is operatively connected to the outlet, the pump configured to receive the associated product that is expelled from the outlet of the first container through the pump inlet, the associated product exiting the pump through the pump outlet;
wherein the pump comprises a second pump outlet, the second pump outlet being operatively connected to the second container for use in pressurizing the second container when the pump is actuated.

7. The dispensing system as defined in claim 6 , wherein the first container has elastically deformable walls.

8. A dispensing system for dispensing an associated substantially viscous product, the dispensing system comprising:
a dispensing system housing;
a first container disposed within the dispensing system housing and having an elastically deformable wall defining a changeable volume for containing the associated product, the elastically deformable wall expandable between an unexpanded state and an expanded state, the first container comprising an outlet through which the associated product is expelled, wherein potential energy stored in the deformable wall in the expanded state is operable to expel the associated product from the first container through the outlet;
a selectively engage-able valve operatively fluidly connected to the outlet for controlling the expulsion of a predetermined amount of the associated product from the outlet; and
an actuator operatively coupled to the valve to selectively engage the valve;
wherein the selectively engage-able valve defines a fixed volumetric region from which the predetermined amount of associated product is expelled and wherein the selectively engage-able valve comprises a valve inlet and a valve outlet;
wherein the valve comprises a displacement member moveable between a first and a second position.
