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.
Claims22
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, and
- a 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, and
- contracting 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.
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, and
- a 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, and
- contracting 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.
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 having at least one fluid flow opening formed therein, and
- a valve having at least one fluid flow opening formed therein, the valve structured for:
- expanding to an elongated state wherein a tip of the valve extends into the fluid flow opening of the base to create a fluid communication seal between the fluid repository and the dispensing orifice, and
- contracting to a compressed state upon application of a threshold fluid pressure wherein the tip of the valve dissociates from the fluid flow opening of the base to create a pathway for communicating fluid from the fluid repository through the fluid flow opening of the base, through the fluid flow opening of the valve, and to the dispensing orifice.
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 having at least one fluid flow opening formed therein;
- and
- a valve having at least one fluid flow opening formed therein, the valve structured for:
- expanding to an elongated state wherein a tip of the valve extends into the fluid flow opening of the base to create a fluid communication seal between the fluid repository and the dispensing orifice, and
- contracting to a compressed state upon application of a threshold fluid pressure wherein the tip of the valve dissociates from the fluid flow opening of the base to create a pathway for communicating fluid from the fluid repository through the fluid flow opening of the base, through the fluid flow opening of the valve, and to the dispensing orifice.
