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 positioned within at least a portion of an interior of a nozzle of a fluid container. The plug may include a base portion having at least one fluid flow opening formed therein and a bellows portion. In operation, the bellows portion may expand to an elongated state upon application of a threshold fluid pressure to create a pathway for communicating fluid, and may contract to a compressed state which creates a fluid communication seal between a fluid repository and dispensing orifice of the fluid container.

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 base portion having at least one fluid flow opening formed therein, anda bellows portion structured for: expanding to an elongated state upon application of a threshold fluid pressure to create a pathway for communicating fluid from the fluid repository through the fluid flow opening to the dispensing orifice upon application of a threshold fluid pressure, andcontracting to a compressed state wherein the bellows portion contacts an interior surface of the nozzle to create a fluid communication seal between the fluid repository and the dispensing orifice. 2. The apparatus of claim 1, wherein at least a portion of the base portion of the plug is structured for correspondingly mating with at least a portion of the interior of the nozzle or the fluid repository for retaining the plug in an operative position. 3. The apparatus of claim 1, wherein the plug is structured to establish a predetermined gap distance between the bellows portion and the dispensing orifice in the elongated state of the bellows portion. 4. The apparatus of claim 3, wherein the predetermined gap distance is structured in response to a fluid viscosity. 5. The apparatus of claim 1, further comprising a plurality of fluid flow openings formed in the base portion of the plug. 6. The apparatus of claim 1, further comprising a ring positioned between the bellows portion of the plug and the dispensing orifice. 7. The apparatus of claim 6, wherein the ring comprises a crenellated ring structured to maintain a predetermined gap distance between the bellows portion and the dispensing orifice in the elongated state of the bellows portion. 8. 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. 9. 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. 10. The apparatus of claim 1, wherein at least one of the fluid flow openings is structured in response to a fluid viscosity. 11. A plug apparatus for facilitating fluid flow in a fluid dispensing apparatus comprising a fluid repository in fluid communication with a nozzle, wherein the nozzle includes at least one dispensing orifice formed therein, the plug apparatus comprising: a base portion structured for placement in at least a portion of the interior of the nozzle of the fluid dispensing apparatus, the base portion having at least one fluid flow opening formed therein, anda bellows portion structured for: expanding to an elongated state upon application of a threshold fluid pressure to create a pathway for communicating fluid from the fluid repository through the fluid flow opening to the dispensing orifice upon application of a threshold fluid pressure, andcontracting to a compressed state wherein the bellows portion contacts an interior surface of the nozzle to create a fluid communication seal between the fluid repository and the dispensing orifice.
