## Abstract

A stem of a valve for a container for dispensing pressurized fluid, has an inner channel inside a cylindrical housing connecting the at least one lateral inlet opening at its lower end and an outlet opening at its upper end. The inner channel has a conical shape at its lower end and the diameter of the cylindrical housing is increased towards the lower end of the stem and in particular in the section which corresponds to the section with lateral inlet openings. Both adaptations reinforce the stem and make it more resilient against bending and tensile forces.

## Claims

### Claim 1

A stem of a valve for a container for dispensing pressurized fluid, said stem comprising:
a lower stem end having at least one lateral inlet opening;
an upper stem end having an outlet opening; and
an inner channel inside a cylindrical housing connecting the at least one lateral inlet opening and the outlet opening;
wherein the inner channel has a parabolic shape at a lower inner channel end of the inner channel.

### Claim 2 (depends on 1)

The stem according to claim 1, wherein the cylindrical housing exteriorly broadens toward the lower stem end.

### Claim 3 (depends on 1)

The stem according to claim 1, wherein the lower stem end has a flange.

### Claim 4 (depends on 1)

The stem according to claim 1, wherein a top sealing part is provided around the outlet opening.
