Abstract
This multipurpose device for dispensing paints or chemicals replaces aerosol cans and custom equipment for spraying paint. Constructed of stainless steel, brass, and Teflon®, the reusable chemical caddie can be used to dispense solvents, paints, and a broad range of materials which will not corrode stainless steel. The reusable chemical caddie eliminates the contamination of the atmosphere with traditional propellants, utilizing compressed air as a propellant. The reusable nature of the reusable chemical caddie eliminates the contamination that results from residual toxic materials and that are invariably discarded when traditional spray cans are discarded into landfills. It is portable, and with an increased capacity as compared to traditional spray cans, is ideally suited for commercial applications.
Claims4
A reusable chemical caddie consisting of:
- A. a cylindrical stainless steel tank made of type 304 or 316L stainless steel;
- B. said tank having a top surface positioned opposite a base of said tank;
- C. said tank having an oval shaped opening in the top surface;
- D. said tank having a seal integrally affixed to said opening;
- E. said tank having a lid which fits tightly into said opening;
- F. said tank having an attachment mechanism affixed to the top surface, so that in a first position the lid is held tightly to the integrated seal, and in a second position, the lid may be removed to permit the tank to be filled with a liquid material;
- G. said tank having at least four threaded connections in said top surface, into which the following assemblies are affixed:
- i. a dispensing assembly,
- ii. a pressure relief assembly,
- iii. a stirring assembly,
- iv. a pressurization assembly;
- H. said dispensing assembly consisting of:
- i. an internal dip tube attached to one of the threaded connections, extending to the bottom of said tank,
- ii. a first set of brass connectors attached to the threaded connection connected to said dip tube,
- iii. a pressure regulator attached to the first set of brass connectors,
- iv. a length of Teflon® tubing, enmeshed in stainless steel, with couplings to affix a first end to said pressure regulator,
- v. a second set of brass connectors, attached on one end to the Teflon® tubing,
- vi. a flow control valve, having an inlet and an outlet, connected to said inlet to said second set of brass connectors,
- vii. a third set of brass connectors, attached to said outlet of said control valve,
- viii. a nozzle assembly with release mechanism, said assembly having an adjustable nozzle which controls the pattern of material discharged from said nozzle;
- I. said pressure relief assembly being constructed so as to release pressure from said tank whenever the pressure exceeds a value that is less than or equal to the rated value of said tank;
- J. said stirring assembly consisting of:
- i. an agitator,
- ii. a shaft, onto which the agitator is attached at a first end,
- iii. a port, which is permanently affixed to said tank, and through which the shaft passes,
- iv. a swivel seal assembly, attached to said port;
- and,
- K. said swivel seal assembly consisting of:
- i. a threaded swivel assembly with a cylindrical opening,
- ii. said cylindrical opening being threaded at the outer end and having smooth walls at the interior end,
- iii. said swivel seat having an O-Ring which fits snugly within the cylindrical opening, through which the shaft passes snugly,
- iv. said O-Ring having a compression fitting and compression screw which compress the O-Ring against the shaft, forming a seal of sufficient strength to withstand the pressure of said tank.
