Figure 1 is an illustration of the custom color spray paint can that can be seen in use. The containers may be filled with a variety of fluids to facilitate in the matching of specific colors. This convenience is particularly useful in repair work and the expedited application of paint.

Figure 2 is a figure showing the primary embodiment of the present invention. The space between the guide tube and the outside container is filled with paint or other fluid and with the domed top attached, pressurization of the contents will occur. To prevent aeration of the fluid via the compressed gas, the guide tube extends above the surface level of the added fluid. A sight glass is incorporated into the wall of the outside container to facilitate proper fluid level while filling. Due to the variety of fluids or mixtures allowed in this invention, a particle filter is attached to the base of the spray nozzle feed tube to prevent nozzle clogging.

Figure 3 is a view showing the level of paint or other fluid allowed with the primary embodiment. The guide tube may vary in height allowing more or less fluid in the cavity. For aeration of the contents, the guide tube is not necessary. The guide tube may also vary in diameter depending on the size of the pressurization cartridge.

Figure 4 is a figure showing the system ready for pressurization. For pressurization to occur, the threaded cap is rotated on its threads to seat the puncturing pin firmly into the gas cartridge.

Figure 5 is a view showing a screw-top type engagement system for pressurization of the container. With the domed cap in place and an unused gas cartridge in the guide tube, all that is required to pressurize the contents is the final quarter turn of the screw-type cap. The quarter turn is enough to bring the puncturing pin in contact with the gas cartridge. The cartridge is punctured and the contents are pressurized.

Figure 6 is an embodiment where the container is pressurized by deforming the dome cap to push the puncturing pin into the gas cartridge to pressurize the container. The cap is made of tough flexible material that will not leak once pressurized, but with enough flex to allow the puncturing pin to strike the pressurized gas cartridge.

Figure 7 is a sectional view of the primary embodiment showing all the major components of the device. Shown is the domed top and outside containing attached prior to pressurization. This sectional view encompasses both the primary puncture system and the alternate flexible top puncturing system. The offset nature of the spray nozzle feed tube is clearly depicted so as not to interfere with the pressurization components.

Figure 8 is an alternate embodiment of the invention having the charging gas cartridge removed from the container. The paint or fluid is pressurized by mating the cartridge carrier with the inlet member, thus flowing the gas into the container. This embodiment allows for maximum utilization of internal space and also has the capability to recharge the container without exposing the contents.

Figure 9 is a view showing the components of the alternate embodiment with the addition of paint or other fluid wherein the top is ready for attachment to the container housing.

Figure 10 is an illustration showing that once the paint or fluid has been added to the container, the domed top is secured ensuring an effective seal. The cartridge carrier is then mated with the charging port for compressed gas transfer and container pressurization.

Figure 11 is a view where the carrier is threaded into the charging port and the gas cartridge is compromised, thus flowing the gas into the container. The internal pressure of the container due to the addition of compressed gas is maintained by the one-way valves located in the spray nozzle assembly and the inlet member in addition to the sealed cap structure and the container.

Figure 12 is a view where the container has been charged with compressed gas, and the paint or other fluid is discharged via the spray nozzle.
