Abstract

Provided is a tube fitment used in a fitment valve assembly having a vertical cylindrical housing and a horizontal cylindrical channel connected to each other in a T-shape, the vertical housing having a top section, a middle section, and a lower section, the top section of the housing having a front wall and a partially open back wall, where the opening is the locus for connecting a spout valve assembly; the horizontal cylindrical channel having a first opening at the first end proximate to the joint of the T-shaped tube fitment and at the top of the horizontal cylindrical channel; having an activator pin and an O-ring situated in the second section of the vertical cylindrical housing that is narrower that said first section of said vertical cylindrical housing.

First claim

The invention claimed is:

1. A tube fitment used in a fitment valve assembly comprising:
(I) a vertical cylindrical housing having a top section, a middle section, and a lower section, and
(II) a horizontal cylindrical channel having a bottom portion and a first opening;
wherein said vertical cylindrical housing being vertically connected to said horizontal cylindrical channel at a point approximately centered thereon thereby forming a joint;
wherein said top section of said vertical cylindrical housing comprises a front wall, a first side wall, a second side wall, and a partially open back wall, wherein said partially open back wall is the locus for connecting and attaching a spout-valve assembly to a container that dispenses fluid;
wherein said horizontal cylindrical channel is defined by the front wall, the first side wall, the second side wall, and the partially open back wall of the top section of the vertical cylindrical housing;
wherein said first opening is defined by the bottom portion of the horizontal cylindrical channel, and is positioned at the joint of the horizontal cylindrical channel and the vertical cylindrical housing, such that said first opening connects the bottom of said top section of said vertical cylindrical housing and the top of said middle section of said vertical cylindrical housing;
wherein at the base of said lower section the said vertical cylindrical housing below said first opening in said horizontal cylindrical channel comprises an activator pin;
wherein an O-ring is situated in said middle section of said vertical cylindrical housing that is narrower than said top section of said vertical cylindrical housing,
wherein the partially open back wall of said vertical cylindrical housing includes a tray attached thereto, the tray configured to support said spout-valve assembly attached to the fluid dispensing container.

2. The tube fitment as recited in claim 1 , wherein said front wall, on the inside, comprises a locking groove for locking said tube fitment to said spout-valve assembly.

3. The tube fitment as recited in claim 2 , wherein said front wall comprises a locking hole above said locking groove and a locking pin positioned therein and a twist knob attached to said locking pin for locking said tube fitment to said spout-valve assembly by turning said twist knob movable between an in and an out position.

4. The tube fitment as recited in claim 3 , wherein said top section of said vertical cylindrical housing comprises two J-shaped pull-tabs attached to the two sides of said front wall, such that said vertical cylindrical housing's side walls protrude over the base of said J-shaped pull-tabs.

5. The tube fitment as recited in claim 1 , wherein said tray is U-shaped.

6. The tube fitment as recited in claim 1 , wherein said activator pin is supported by at least one ridge.

7. The tube fitment as recited in claim 6 , wherein said at least one ridge is rectangular.

8. The tube fitment of claim 1 , wherein said activator pin is cylindrical.
