Abstract

A system and method for custom coloring sealant is generally provided with one or more dispensing cartridges, containing a quantity of low viscosity sealant base solution, which in some embodiments is as fluid, or more-so, as common latex paint. One or more such dispensing cartridges are secured within a cartridge case. A coloring agent is added to the dispensing cartridge. The system may then be agitated by hand or in a mechanical agitator, such as a commercial paint shaker, until a desired color is attained. The sealant thickener may then be added and mixed by similar agitation of the system to obtain a non-sag, high viscosity sealant. Embodiments of the cartridge case are provided for use with various mechanical agitators and dispensing cartridges.

Claims

1. A system for providing custom colored sealant;

the system comprising;

at least one dispensing cartridge, having a first end portion with an opening that extends into an open interior compartment of the at least one dispensing cartridge and a cartridge cap that removably secures with the first end of the dispensing cartridge to selectively cover the opening;

a quantity of sealant base solution disposed within the interior compartment of the at least one dispensing cartridge;

a cartridge case having separate first and second end portions of generally identical construction, said end portions being generally cylindrical with solid planar end portions;

the first end portion of the cartridge case including a plurality of cavities that are shaped and sized to receive at least a portion of the at least one dispensing cartridge when the cartridge case is in a mixing position;

the second end portion of the cartridge case having a plurality of cavities that are generally aligned with the cavities in the first end portion of the cartridge case and shaped to receive at least a second end portion of the dispensing cartridge when the cartridge case is in the mixing position, thereby defining a plurality of cartridge receptacles configured to contact an outer surface of the at least one dispensing cartridge;

the first and second end portions of the cartridge case being positioned in a spaced apart relationship with one another with no intervening elements therebetween, thereby being in contact with and supported by the first and second end portions of the at least one dispensing cartridge, when the cartridge case is in the mixing position;

a quantity of sealant thickener; and

a quantity of a coloring agent.

2. The system of claim 1 wherein there are seven dispensing cartridges and seven cartridge receptacles.

3. The system of claim 1 wherein there are more cartridge receptacles than dispensing cartridges and the system is further comprised of at least one balancing weight disposed within at least one of the cartridge receptacles that does not have a dispensing cartridge disposed therein.

4. The system of claim 3 wherein the at least one weight is shaped at least similarly to the at least one dispensing cartridge;

the at least one weight having a weight that is at least similar to a weight of a dispensing cartridge.

5. The system of claim 1 wherein at least one of the cartridge receptacles is formed with a generally circular cross-section, whereby generally cylindrical, rigid, dispensing cartridges may fit within the at least one cartridge receptacle.

6. The system of claim 1 further comprising:

a plunger that is axially, slidably disposed within the dispensing cartridge;

a lip member that extends radially inwardly from the second end portion of the dispensing cartridge, whereby preventing unintentional removal of the plunger from the second end portion of the dispensing cartridge.

7. The system of claim 1 further comprising:

a plunger that is axially, slidably disposed within the dispensing cartridge;

at least one barb that extends radially inwardly from the second end portion of the dispensing cartridge, whereby preventing unintentional removal of the plunger from the second end portion of the dispensing cartridge.

8. The system of claim 1 further comprising:

a plunger that is axially, slidably disposed within the dispensing cartridge;

the second end portion of the dispensing cartridge tapering inwardly to a terminal diameter that is less than a diameter of the plunger, whereby preventing unintentional removal of the plunger from the second end portion of the dispensing cartridge.

9. The system of claim 1 wherein the quantity of sealant base solution has a viscosity of between or equal to 50 to 100,000 centipoise.
