## 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;
a plug positioned within at least a portion of the interior of the nozzle, the plug comprising:
a. an inflow region,
b. an outflow region, and
c. a constriction region positioned between the inflow region and the outflow region establishing a two-way pathway for fluid communication between the inflow region and the outflow region; and,
wherein the plug 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 the plug further includes a retaining segment structured for correspondingly mating with at least a portion of the retaining ridge of the nozzle.

### Claim 4 (depends on 1)

The apparatus of claim 1, wherein at least a portion of the outflow region of the plug is positioned for direct contact and fluid communication with the dispensing orifice.

### Claim 5 (depends on 1)

The apparatus of claim 1, wherein at least one cross-sectional area of the constriction region is structured in response to a fluid viscosity.

### Claim 6 (depends on 1)

The apparatus of claim 1, wherein at least one volumetric space defined by the constriction region is structured in response to a fluid viscosity.

### Claim 7 (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 8 (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 9 (depends on 1)

The apparatus of claim 1, wherein the plug comprises a tube-shaped portion and the constriction region comprises a crimped segment formed at a location between the inflow region and the outflow region.

### Claim 10 (depends on 1)

The apparatus of claim 1, wherein at least a portion of the plug comprises an elastomeric material.
