## Abstract

The combination of a container of a first volume and a fluid containment and dispensing apparatus includes a flexible bag having an inner wall, an outer wall and a collar. The collar comprises a plurality of components, including a collar body, a flange that is attached to the bag, and a top plate having a first aperture therein configured to for connection to a first fluid carrying conduit, the fluid carrying conduit providing for egress of fluid from the bag. The container comprises walls the walls having inner and outer surfaces, and the collar body extends from a wall of the container. The container provides at least one second aperture providing for ingress and egress of fluid to and from a space situated between the outer surface of the bag and the inner surface of the container and the apparatus further comprises a fastener, such as a clamp, to fasten the collar components together.

## Claims

### Claim 1

The combination of a container of a first volume and a fluid containment and dispensing apparatus including a flexible bag having an inner wall, an outer wall and a collar, the collar comprising a plurality of components, including a collar body, a flange that is attached to the bag, and a top plate having a first aperture therein configured to for connection to a first fluid carrying conduit, the fluid carrying conduit providing for egress of fluid from the bag, wherein the container comprises walls the walls having inner and outer surfaces, wherein the collar body extends from a wall of the container, the container providing at least one second aperture providing for ingress and egress of fluid to and from a space situated between the outer surface of the bag and the inner surface of the container, the apparatus further comprising fastening means to fasten the collar components together.

### Claim 2 (depends on 1)

The combination of claim 1, wherein the fluid carrying conduit provides for the ingress of fluid into the bag.

### Claim 3 (depends on 1)

The combination of claim 1, wherein the at least one second aperture is configured to attach to a second fluid carrying conduit configured to carry said fluid engrossing and egressing from the space situated between the outer surface of the bag and the inner surface of the container.

### Claim 4 (depends on 1)

The combination of claim 1, wherein the collar body includes a flange, the top plate aligned with the flange and fastened thereto by the fastening means.

### Claim 5 (depends on 1)

The combination of claim 1, wherein the fastening means is a clamp.

### Claim 6 (depends on 5)

The combination of claim 5, wherein the clamp comprises two elements each having a first end and a second end, wherein the first ends are pivotally connected to one another and wherein the second ends are releasably connectable to one another by a releasable fastener.

### Claim 7 (depends on 6)

The combination of claim 6, wherein one of the second ends has an externally threaded rod attached thereto and the other includes a recess configured to receive the threaded rod, the threaded rod having an internally threaded nut.

### Claim 8 (depends on 5)

The combination of claim 5, wherein the clamp is C-shaped in cross-section comprising upper and lower walls extending from a connecting rear wall.

### Claim 9 (depends on 8)

The combination of claim 8, wherein the dimension extending between the internal surfaces of the upper and lower wall decreases towards the rear wall.

### Claim 10 (depends on 1)

The combination of claim 1, wherein the at least one second aperture is situated in the same wall of the container from which the collar body extends.

### Claim 11 (depends on 1)

The combination of claim 1, comprising two second apertures.

### Claim 12 (depends on 11)

The combination of claim 11, wherein the two second apertures are situated in the same wall of the container from which the collar body extends to opposing sides of the collar body.

### Claim 13 (depends on 1)

The combination of claim 1, further comprising a down pipe within the bag and which extends from the first aperture into a lower part of the bag and towards a bottom wall of the container terminating a small distance away from the inner surface of the bag and the bottom wall.

### Claim 14 (depends on 1)

The combination of claim 1, wherein a cylindrical and hollow boss extends the first aperture formed in the top plate in a direction perpendicular to the plane of the top plate.

### Claim 15 (depends on 14)

The combination of claim 14, wherein the boss extends away from the container.

### Claim 16 (depends on 14)

The combination of claim 14, wherein the boss extends toward the container.

### Claim 17 (depends on 14)

The combination of claim 14, wherein the boss provides for attachment of the fluid carrying conduit and the down pipe to the top plate in alignment with and for the passage of fluid through the first aperture.

### Claim 18 (depends on 1)

The combination of claim 1, further comprising a source of compressed fluid, a conduit connected to the said source of compressed fluid and to the second aperture and extending therebetween.

### Claim 19 (depends on 18)

The combination of claim 18, further comprising a multi-position valve, the valve providing in one position fluid pathway from the source of compressed fluid through the second aperture to the space between the outer surface of the bag and the inner surface of the container, and in a second position a fluid pathway from the space between the outer surface of the bag and the inner surface of the container to a atmosphere.

### Claim 20 (depends on 1)

The combination of claim 1, further comprising a pump in fluid communication with the first fluid carrying conduit, the pump configured to cause egress of fluid from the bag via said first fluid carrying conduit.

### Claim 21 (depends on 1)

A method of containing fluid in and dispensing fluid from a vessel comprising the steps of:
introducing fluid into the flexible bag of the combination of claim 1;
allowing fluid situated in the space between the outer surface of the bag and the inner surface of the container to egress via the at least one second aperture;
and dispensing fluid from the flexible bag through the first aperture by introducing through the second aperture fluid under pressure in the space between the outer surface of the flexible bag and the inner surface of the container.
