Benefits of technology
[0010]It is another object of this invention to provide an improved dispensing system for viscous fluids capable of triple sealing the tube contents from the atmosphere so as to eliminate the unwanted sealing of the tube by the hardening on the caulk.
[0011]It is a further object of this invention to provide an improved dispensing system for viscous fluids that allows for a controlled dispersing of the tube's contents.
[0013]It is yet a further object of this invention to provide an improved dispensing system for viscous fluids that may be closed without the ejection of any further caulk from the tube.
[0014]Lastly, it is an object of this invention to provide for a method of maximizing the use of the tube's contents and preventing waste by unnecessary ejection and or hardening.
Problems solved by technology
Since caulk is air-cured, the inability of the user to reseal the tube or cartridge results in the remainder of the caulking material going to waste.
The obvious solution has been to utilize a resealable cap, and there is a plethora of prior art caps that purport to allow the reuse of these opened containers, however they all fail in at least one of the following problem areas.
First, to engage and seal the cap causes an unwanted amount of the caulk to be ejected from the end of the cap.
Second, the leading edge of the caulking does contact enough air to harden, usually jamming the cap and preventing its opening because there are not enough seal barriers between the atmosphere and the tube contents when closed.
Third, the flow of caulking that is dispensed through the cap is not sizeable.
This of course is also a problem when a cap is not used.
Cutting of the sealed nozzle provides for the inability for the user to control the flow of the caulk during application as nothing regulates the flow of caulk through the nozzle other than pressure applied to the tube or cylindrical cartridge, making it difficult to maintain a smooth bead throughout the application.

A two piece dispensing system for viscous fluids includes a valve body and a valve cap. The valve body threadingly engages the factory nozzle of the viscous fluid tube / cartridge. The hollow valve body and valve cap are slidably engaged via rotational engagement to allow the discharge of fluid or to seal the container. The valve body has two groves with a circumferential scraping edge to collect the fluid, prevent unwanted ejection of the fluid from the tube, and help seal the tube's contents from the atmosphere. The dispensing system is matingly conformed so as to utilize a triple atmospheric seal when closed.
Description
BACKGROUND OF THE INVENTION[0001]The present invention relates to the art of dispensing viscous fluids, such as caulk, paste, putty, etc. In Particular the present invention relates to a self-cleaning, reusable dispensing system for caulk.[0002]Commercially available caulk comes in either a pliable polymer tube or a cylindrical cartridge for use with a caulking gun. Whether in a tube or cylindrical cartridge the manufacture provides a sealed nozzle for application of the caulk that the user must cut in order to dispense the caulk. Once cut, the nozzle is non-resealable. Since caulk is air-cured, the inability of the user to reseal the tube or cartridge results in the remainder of the caulking material going to waste.[0003]The obvious solution has been to utilize a resealable cap, and there is a plethora of prior art caps that purport to allow the reuse of these opened containers, however they all fail in at least one of the following problem areas.[0004]First, to engage and seal the...
