Abstract
The present invention relates generally to a valve for a flexible plastic container and more particularly to a valve for dispensing particulate containing liquids.
Claims5
A valve body for a liquid container adapted for use with a fitment comprising:
- a valve body having a proximal end having a fluid inlet and a distal end having a fluid outlet and a generally cylindrical shaped wall having an outer surface and defining a fluid pathway between the fluid inlet and the fluid outlet;
- a valve member positioned in the fluid pathway and moveable from a closed position where no liquid can flow through the fluid outlet to an open position where fluid can flow through the fluid outlet;
- a first ring on the outer surface proximate the proximal end and having a first diameter and a generally rounded outer profile;
- and
- a second ring on the outer surface spaced axially inwardly from the first ring in a position between the first ring and the distal end, the second ring having a second diameter greater than the first diameter and having a generally flat surface facing the distal end, the first ring is dimensioned to releasably engage an interior surface of the fitment when inserted a first distance inside the fitment to define a first position, and the second ring is dimensioned to lock to the body when inserted a second distance inside the fitment to define a second position, the second distance being greater than the first distance.

A closure assembly for a fluid container adapted for use with a fitment comprising:
- a fitment having a flange for connecting to a sidewall of the container, the fitment having an interior surface;
- a valve body having a proximal end having a fluid inlet and a distal end having a fluid outlet and a generally cylindrical shaped wall having an outer surface and defining a fluid pathway between the fluid inlet and the fluid outlet;
- a valve member positioned in the fluid pathway and moveable from a closed position where no liquid can flow through the fluid outlet to an open position where fluid can flow through the fluid outlet;
- a first ring on the outer surface proximate the proximal end and having a first diameter and a generally rounded outer profile;
- and
- a second ring on the outer surface spaced axially inwardly from the first ring in a position between the first ring and the distal end, the second ring having a second diameter greater than the first diameter and having a generally flat surface facing the distal end, the first ring is dimensioned to releasably engage the interior surface of the fitment when inserted a first distance inside the fitment to define a first position, and the second ring is dimensioned to lock to the body to the fitment when inserted a second distance inside the fitment to define a second position, the second distance being greater than the first distance.
