## 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 having an inflow region and an outflow region; and
a filter screen positioned between an outflow region of the plug and the dispensing orifice, the filter screen 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 the filter screen is affixed to at least a portion of the outflow region of the plug.

### Claim 5 (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 an outflow region of the plug and the dispensing orifice.

### Claim 6 (depends on 5)

The apparatus of claim 5, wherein the predetermined gap distance is structured in response to a fluid viscosity.

### Claim 7 (depends on 1)

The apparatus of claim 1, wherein the filter screen includes a plurality of cross-hatched openings formed therein.

### Claim 8 (depends on 8)

The apparatus of claim 8, wherein a cross-sectional area of at least one of the openings is structured in response to a fluid viscosity.

### Claim 9 (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 10 (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.
