## Abstract

In various embodiments, the invention provides enhanced structures, devices, and techniques that allow fluids and liquid products, such as cosmetics, to dispense in a more even, smoother, and more predictable manner from fluid containers.

## Claims

### Claim 1

An apparatus for dispensing fluid, the apparatus comprising:
a fluid repository in fluid communication with a nozzle, wherein the nozzle includes at least one dispensing orifice formed therein; and,
a plug positioned within at least a portion of the interior of the nozzle, the plug comprising:
a tip, and
a base having at least one longitudinal opening formed therein, wherein the longitudinal opening is structured to create a pathway for communicating fluid from the fluid repository to the dispensing orifice upon application of a threshold fluid pressure.

### Claim 2 (depends on 1)

The apparatus of claim 1, further comprising a retaining ridge formed in at least a portion of the interior of the nozzle.

### Claim 3 (depends on 2)

The apparatus of claim 2, wherein at least a portion of the base of the plug is structured for correspondingly mating with at least a portion of the retaining ridge in the nozzle.

### Claim 4 (depends on 1)

The apparatus of claim 1, wherein at least a portion of the plug is positioned within the interior of the nozzle to establish a predetermined gap distance between the tip of the plug and the dispensing orifice.

### Claim 5 (depends on 4)

The apparatus of claim 4, wherein the predetermined gap distance is structured in response to a fluid viscosity.

### Claim 6 (depends on 1)

The apparatus of claim 1, further comprising a plurality of longitudinal openings formed in the base of the plug.

### Claim 7 (depends on 1)

The apparatus of claim 1, further comprising at least one tortured path formed on the tip of the plug.

### Claim 8 (depends on 7)

The apparatus of claim 7, wherein the tortured path comprises a plurality of segments positioned generally transversely with respect to a longitudinal axis of the plug.

### Claim 9 (depends on 7)

The apparatus of claim 7, wherein the tortured path comprises a plurality of segments positioned at an angle with respect to a longitudinal axis of the plug.

### Claim 10 (depends on 7)

The apparatus of claim 7, wherein the tortured path comprises a plurality of segments, wherein a thickness of at least one of the plurality of segments is structured as a percentage of a height of the tip of the plug.

### Claim 11 (depends on 7)

The apparatus of claim 7, wherein the tortured path is structured in response to a fluid viscosity.

### Claim 12 (depends on 1)

The apparatus of claim 1, wherein the plug is structured to communicate fluid therethrough at a threshold fluid pressure not exceeding a pressure applied to the fluid repository.

### Claim 13 (depends on 1)

The apparatus of claim 1, wherein the plug is structured to communicate fluid therethrough at a threshold fluid pressure independent of a pressure applied to the fluid repository.

### Claim 14 (depends on 1)

The apparatus of claim 1, further comprising a plurality of longitudinal openings formed in the base of the plug and at least one tortured path segment formed on the tip of the plug.
