## Abstract

A valve for an aerosol device includes a valve assembly receivable in an opening provided in a container of the aerosol device to close the opening and includes a seal between the valve assembly and the container.

## Claims

### Claim 1

A valve assembly for an aerosol device, the valve assembly, in use, being receivable in an opening provided in a container of the aerosol device to close said opening, the valve assembly comprising:
means on an outside of the valve assembly or providing a seal with the container when positioned in the opening thereof;
a flat portion which, in use, faces towards the interior of the container and provides a flat base for an interior of the aerosol device;
channels immediately adjacent the flat portion which provide access to an interior of the valve assembly;
wherein component parts of the valve assembly comprise a valve stem, a spring and a valve chamber, and are arranged in a valve body contained therein by a sealing piece to provide a self-contained valve assembly; and
wherein the valve stem and the valve chamber define a space therebetween that contains one dose to be released when the valve assembly is actuated.

### Claim 2 (depends on 1)

The valve assembly according to claim 1, wherein a part of the valve assembly is cylindrical.

### Claim 3 (depends on 1)

The valve assembly according to claim 1, wherein said means for providing a seal extends completely around a periphery of the valve assembly.

### Claim 4 (depends on 1)

The valve assembly according to claim 1, wherein the flat portion is formed by a body part of the valve assembly.

### Claim 5 (depends on 1)

The valve assembly according to claim 1, wherein the valve body and the sealing part are snap-fit together.

### Claim 6 (depends on 1)

The valve assembly according to claim 1, wherein the component parts of the valve assembly comprise a seat gasket positioned between the valve chamber and the sealing piece.

### Claim 7 (depends on 6)

The valve assembly according to claim 6, wherein the seat gasket surrounds the valve stem and is capable of sealing an aperture provided in the valve stem.

### Claim 8 (depends on 1)

The valve assembly according to claim 1, wherein the valve stem is movable within the valve chamber.

### Claim 9 (depends on 1)

The valve assembly according to claim 1, wherein the seal means comprises an elastomeric ring.
