## Abstract

A resealable closure and valve assembly adapted to be coupled to a container to selectively control the dispensing of liquid from the container. The resealable closure and valve assembly includes a non-mechanically biased stop selectively engageable with a passageway to selectively seal the passageway from a dispensable product, such as a liquid contained within a container. In some embodiments, the stop is adapted to reseal the passageway by the force of weight applied to the stop by fluid in the container. In some embodiments, the stop is adapted to reseal the passageway via a suction force.

## Claims

### Claim 1

A liquid container having a resealable outlet for use on a dispenser for dispensing liquid form the container, the container outlet comprising:
a passageway; and
a non-mechanically biased stop selectively engageable with the passageway to seal the passageway from liquid in the container,
wherein the passageway is accessible beneath the stop by a dispenser peg for insertion in the passageway to push the stop inwardly of the passageway toward a container interior, the stop comprising:
a tapered body;
a first annular flange coupled to the tapered body;
a first skirt extending away from the first annular flange;
a second annular flange coupled to the first skirt; and
a second skirt extending away from the second annular flange; and
wherein the stop is adapted to reseal the passageway by the force of weight applied to the first and second annular flange by fluid in the container.

### Claim 2

A resealable closure and valve assembly adapted to be coupled to a container to selectively control the dispensing of liquid from the container, the resealable closure and valve assembly comprising:
a cap having an opening and adapted to be coupled to an opening of a container;
a tubular passageway coupled to the opening in the cap, the tubular passageway having a first end coupled to the opening in the cap and a second end extending distally relative to the opening in the cap; and
a non-mechanically biased stop selectively engageable with the second end of the tubular passageway to selectively seal the passageway from dispensing liquid contained within the container, the stop comprising:
a tapered body dimensioned and configured to extend into the second end of the tubular passageway and selectively form a seal against an inner surface of the tubular passageway; and
a first annular flange coupled to the tapered body, wherein the stop is adapted to reseal the passageway by the force of weight applied to the first annular flange by fluid in the container.

### Claim 3 (depends on 2)

The resealable closure and valve assembly of claim 2, wherein the stop further comprises a first skirt extending away from the first annular flange, the first skirt at least partially defining a tapered annular recess for receiving the second end of the passageway, at least a portion of the first skirt engages an outer surface of the passageway when the stop sealingly engages the passageway.

### Claim 4 (depends on 3)

The resealable closure and valve assembly of claim 3, wherein the stop further comprises a second annular flange coupled to the first skirt, and wherein the stop is adapted to reseal the passageway by the force of weight applied to the second annular flange by fluid in the container.

### Claim 5 (depends on 4)

The resealable closure and valve assembly of claim 4, wherein the stop further comprises a second skirt extending away from the second annular flange.

### Claim 6

(canceled)
