Abstract

The present disclosure provides a dispenser for pressurized material. In an embodiment, the dispenser for pressurized material includes a container half having an exposed edge and a closure member at the exposed edge. The container half has a cup half in an interior top portion. The dispenser includes a reciprocal container half having a reciprocal exposed edge and a reciprocal closure member at the reciprocal exposed edge. The reciprocal container half has a reciprocal cup half in an interior top portion. The closure member and the reciprocal closure member matingly engage along the exposed edges to attach the container half to the reciprocal container half and form a container. The dispenser includes a sleeve bag on valve (SBoV) assembly in an interior of the container. The SBoV assembly includes a valve seat. The cup and the reciprocal cup support the valve seat to secure the SBoV assembly in the container.

First claim

The invention claimed is:

1. A dispenser for pressurized material comprising:
a container half having an exposed edge and a closure member at the exposed edge, the container half having a cup half in an interior top portion;
a reciprocal container half having a reciprocal exposed edge and a reciprocal closure member at the reciprocal exposed edge, a reciprocal cup half in an interior top portion;
the closure member and the reciprocal closure member matingly engaged along the exposed edges, attaching the container half to the reciprocal container half to form a container;
a sleeve bag on valve (SBoV) assembly in an interior of the container, the SBoV assembly comprising (i) a valve extending from the top portion of the container, (ii) a bag, and (iii) an elastic sleeve disposed around the bag, the elastic sleeve providing a pressure on the bag; and
a valve cap comprising a first leg flexibly attached to the container half and a second leg flexibly attached to the reciprocal container half, the valve cap in fluid communication with the valve,
wherein flexibly attached comprises a structural connection between the valve cap and each of the container half and the reciprocal container half that enables hinge movement between the valve cap and each of the container half and the reciprocal container half.

2. The dispenser of claim 1 wherein the SBoV assembly comprises a valve seat; and
the cup and the reciprocal cup support the valve seat to secure the SBoV assembly in the container.

3. The dispenser of claim 1 wherein the container is rigid.

4. The dispenser of claim 1 wherein the container half and the reciprocal container half each is composed of a polymeric material.

5. The dispenser of claim 4 wherein the container half and the reciprocal container half each comprise polyethylene.

6. The dispenser of claim 1 wherein the container half and the reciprocal container half each comprises an outer surface with a grip structure.

7. A process comprising:
providing a container half having an exposed edge and a closure member at the exposed edge, the container half having a cup half in an interior top portion;
providing a reciprocal container half having a reciprocal exposed edge and a reciprocal closure member at the reciprocal exposed edge, a reciprocal cup half in an interior top portion;
inserting a sleeve bag on valve (SBoV) assembly in an interior of the container half, the SBoV comprising (i) a valve extending from the top portion of the container, (ii) a bag and (iii) an elastic sleeve disposed around the bag, the elastic sleeve providing a pressure on the bag;
providing a valve cap comprising a first leg flexibly attached to the container half and a second leg flexibly attached to the reciprocal container half, the valve cap in fluid communication with the valve, wherein flexibly attached comprises a structural connection between the valve cap and each of the container half and the reciprocal container half that enables hinge movement between the valve cap and each of the container half and the reciprocal container half;
joining, with the closure members, the container halves along the exposed edge; and
forming a container with the SBoV in the container interior.

8. The process of claim 7 wherein the SBoV comprises a valve seat, the process comprising supporting the valve seat with the cup half and the reciprocal cup half.

9. The process of claim 8 wherein the valve seat comprises a lip portion, the process comprising supporting the cup portion with a shelf of the cup and a reciprocal shelf of the reciprocal cup.
