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. In one embodiment, a plug is inserted into the nozzle of a squeeze tube. The plug has embossments on its surface that form longitudinal openings for the tube's fluid contents to dispense in a controlled fashion. In one embodiment, a plug is positioned within at least a portion of the interior of the nozzle of a fluid container. The plug includes a tip and a base having at least one longitudinal opening structured to create a pathway for communicating fluid from the fluid repository to the dispensing orifice on at least a portion of an outside surface of the plug upon application of a threshold fluid pressure.

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 with at least one tortured path formed on said tip of said plug defined by a plurality of raised segments, anda base having at least one longitudinal opening formed on at least a portion of an outside surface of the base, wherein the longitudinal opening is structured to create a pathway for communicating fluid from the fluid repository to the dispensing orifice on at least a portion of an outside surface of the plug upon application of a threshold fluid pressure. 2. The apparatus of claim 1, further comprising a retaining ridge formed in at least a portion of the interior of the nozzle. 3. 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. 4. 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. 5. The apparatus of claim 4, wherein the predetermined gap distance is structured in response to a fluid viscosity. 6. The apparatus of claim 1, further comprising a plurality of longitudinal openings formed in the base of the plug. 7. The apparatus of claim 1, wherein the tortured path comprises a plurality of segments positioned generally transversely with respect to a longitudinal axis of the plug. 8. The apparatus of claim 1, wherein the tortured path comprises a plurality of segments positioned at an angle with respect to a longitudinal axis of the plug. 9. The apparatus of claim 1, 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. 10. The apparatus of claim 1, wherein the tortured path is structured in response to a fluid viscosity. 11. 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. 12. 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.
