Abstract

A dispensing fitment assembly includes a fitment assembly and a dispensing probe. The fitment assembly includes a fitment housing and a plug. The fitment housing is configured to operatively couple to a container opening of a fluid container. The plug is positioned within an interior portion of the fitment housing. The plug is slidingly movable between an open and closed position. Engagement between the dispensing probe and the interior surface of the plug is configured to move the plug from the closed position to the open position. Disengagement between the dispensing probe and the interior surface of the plug is configured to move the plug from the open to closed position.

First claim

What is claimed is:

1. A dispensing fitment assembly for selectively dispensing fluid from a fluid container, the dispensing fitment assembly comprising:
a fitment assembly, comprising:
a fitment housing configured to operatively couple to a container opening of the fluid container, the fitment housing having an interior portion defined therein,
a plug positioned within the interior portion of the fitment housing, the plug being slidingly movable between an open position and a closed position, the plug comprising a plurality of flanges and a lip, wherein each flange includes a tapered leading portion at an interior surface of the plug, and wherein the lip is defined at an exterior surface of the plug, the exterior surface of the plug facing the fitment housing and the interior surface of the plug being opposite the exterior surface of the plug; and

a dispensing probe engageable with at least the interior surface of the plug, the engagement between the dispensing probe and the interior surface of the plug configured to move the plug from the closed position to the open position,
the dispensing probe being disengageable from the interior surface of the plug, the disengagement between the dispensing probe and the interior surface of the plug configured to move the plug from the open position to the closed position,

when the plug is in the closed position, the dispensing probe is configured to be fluidly isolated from the fluid container to restrict flow of fluid from or to the fluid container,
when the plug is in the open position, the dispensing probe is configured to be in fluid communication with the fluid container to permit flow of fluid from or to the fluid container.

2. The dispensing fitment assembly of claim 1 , wherein the fitment housing comprises a first end and a second end longitudinally opposite to the first end.

3. The dispensing fitment assembly of claim 2 , wherein an entirety of the plug is disposed proximal to the second end of the fitment housing and longitudinally away from the first end of the fitment housing.

4. The dispensing fitment assembly of claim 1 , wherein the dispensing probe having an end portion, the end portion having a flared portion, the flared portion of the end portion abutting the tapered leading portion of at least a first flange of the plurality of flanges to disengage the plug from the interior portion and thereby move the plug from the closed position to the open position.

5. The dispensing fitment assembly of claim 4 , wherein the plug comprises a recess, the end portion of the dispensing probe terminating in a distal end surface, wherein, when the flared portion of the end portion abuts the tapered leading portion of at least the first flange of the plurality of flanges, the distal end surface of the end portion of the dispensing probe is received within the recess of the plug.

6. The dispensing fitment assembly of claim 4 , wherein the interior portion of the fitment housing includes a first portion and a second portion, the second portion being proximal to the second end of the fitment housing, a first cross-sectional area of the first portion being greater than a second cross-sectional area of the second portion.

7. The dispensing fitment assembly of claim 6 , wherein the lip engages against the second portion of the fitment housing when the plug is in the closed position.

8. The dispensing fitment assembly of claim 7 , wherein engagement between the dispensing probe and the interior surface of the plug detaches the engagement between the lip and the second end of the fitment housing to move the plug from the closed position to the open position.

9. The dispensing fitment assembly of claim 4 , wherein the end portion of the dispensing probe includes a distal portion and a proximal portion, a cross-sectional area of the flared portion being greater than a cross-sectional area of the distal portion or a cross-sectional area of the proximal portion.

10. The dispensing fitment assembly of claim 1 , wherein the fitment housing comprises one or more vent passages defined proximal to the first end of the fitment housing, the one or more vent passages being configured to place the fluid container in fluid communication with an exterior of the fluid container so as to maintain the fluid container at a pressure greater than vacuum during dispensing of fluids out of the fluid container and, optionally, at atmospheric pressure during periods of not dispensing of fluids out of the fluid container.

11. A dispensing fitment assembly for selectively dispensing fluid from a fluid container, the dispensing fitment assembly comprising:
a fitment assembly, comprising:
a fitment housing coupled to a container opening of the fluid container, the fitment housing having an interior portion defined therein, the interior portion extending between a first end and a second end longitudinally opposite to the first end,
a plug positioned within the interior portion of the fitment housing, an entirety of the plug being disposed proximal to the second end of the fitment housing and longitudinally away from the first end of the fitment housing, the plug being slidingly movable relative to the interior portion between an open position and a closed position, the plug comprising a plurality of flanges and a lip, wherein each flange includes a tapered leading portion at an interior surface of the plug, and wherein the lip is defined at an exterior surface of the plug, the exterior surface of the plug facing the fitment housing and the interior surface of the plug being opposite the exterior surface of the plug; and

a dispensing probe engageable with the plug, the engagement between the dispensing probe and the plug configured to move the plug from the closed position to the open position,
the dispensing probe being disengageable from the plug, the disengagement between the dispensing probe and the plug configured to move the plug from the open position to the closed position,
when the plug is in the closed position, the dispensing probe is fluidly isolated from the fluid container to restrict flow of fluid from or to the fluid container,
when the plug is in the open position, the dispensing probe is in fluid communication with the fluid container to permit flow of fluid from or to the fluid container.

12. The dispensing fitment assembly of claim 11 , wherein the dispensing probe engages with the fitment housing proximal to the first end of the fitment housing.

13. The dispensing fitment assembly of claim 11 , further comprising a one-way flow control valve positioned within the dispensing probe, the one-way flow control valve being configured to permit passage of fluids in a dispensing direction and restrict passage of fluids in directions other than the dispensing direction.

14. The dispensing fitment assembly of claim 11 , further comprising a fitment connector coupled to the fitment housing, the fitment connector comprising a first end, a second end opposite to the first end and an internal passage extending between the first end of the fitment connector and the second end of the fitment connector.

15. The dispensing fitment assembly of claim 14 , wherein the second end of the fitment connector is disposed longitudinally away from the plug when the plug is in the closed position.

16. The dispensing fitment assembly of claim 15 , wherein a cross-sectional area of the second end of the fitment connector being less than a cross-sectional area of the plug, such that the second end of the fitment connector captures the plug within the internal passage of the fitment connector when the p
