Abstract

A paint containing module comprises a reservoir portion for containing a liquid such as paint. The reservoir portion is fabricated from a flexible transparent material and this portion communicates via an aperture with a liquid discharge portion having an arcuate arm with a liquid passageway, the passageway communicates with the reservoir portion at one end of the arm and with a tip portion at the other end of the arm. When the tip is held in close proximity to the nozzle of a spray gun the liquid is drawn via the passageway and discharged.

Claims

1. In a spray gun adapted to be used with a source of pressurized gas, said gun of the type having a cylindrical barrel portion with a central aperture therethrough, said aperture communicating at an exit end of said barrel with a nozzle and at an entrance end of said barrel with a valve mechanism adapted to be manually actuated to permit pressurized gas to flow through said central aperture to be discharged at said nozzle end under relatively high velocity, in combination therewith apparatus for use with said gun to provide for dispersement of a liquid by means of such high velocity gas, comprising:

a. holder means positioned on the bottom of said barrel of said gun near said exit end, and b. a cylindrical liquid container, said container having a bottom liquid reservoir portion fabricated from a flexible, transparent material, and a top liquid discharge portion communicating with said reservoir, said top liquid discharge portion comprising a first collar means adapted to coact with and be rigidly held by said holder means, and second means comprising an outwardly extending arcuate arm with an aperture therein communicating at one end with said reservoir portion and at said other end with a tip portion of said arm, said aperture being of a substantially smaller diameter than said reservoir portion to permit said liquid to be drawn into said aperture by capillary action, said arcuate arm positioned by said collar and said holder means in a manner such that said tip of said arm is positioned in close proximity to said nozzle, with said cylindrical liquid container positioned beneath said high velocity air stream, whereby when high velocity gas is being emitted by said nozzle, said liquid is drawn from said reservoir and dispersed, said high velocity stream causing said liquid to be withdrawn from said reservoir due to said capillary action and the attendant compression of said flexible container.

2. The apparatus according to claim 1 wherein said holder means when coacting with said collar means causes said container to be positioned at an acute angle with respect to the main axis of said barrel.

3. The apparatus according to claim 1 wherein said bottom liquid reservoir portion of said container includes a series of pleats on the surface thereof forming an accordian-like structure capable of compressing as said liquid is drawn from said reservoir to thereby aid in discharging liquid.

4. The apparatus according to claim 3 further including a. a protective cylindrical cage adapted to surround said accordian-like reservoir portion, said cage fabricated from a rigid material and dimensional to permit easy compression of said accordian-like portion, while serving to prevent a user from inadvertently compressing the same to thereby discharge said liquid.

5. The apparatus according to claim 2 further comprising:

a. adjustment means pivotally coupling said holder means to said barrel portion of said spray gun to enable a user to select any one of a plurality of said acute angles.

6. The apparatus according to claim 1 further comprising:

a. a stopper assembly haVing a grasping portion and an elongated tip portion of a diameter slightly less than the diameter of said aperture of said arcuate arm for insertion therein to prevent any liquid from emanating from said reservoir portion of said container when the same is not being used.

7. In a spray gun adapted to be used with a source of pressurized gas, said gun of the type having a cylindrical barrel portion with a central aperture therethrough, said aperture communicating at an exit of said barrel with a nozzle and at an entrance end of said barrel with a valve mechanism adapted to be manually actuated to permit pressurized gas to flow through said central aperture to be discharged at said nozzle end under relatively high velocity, in combination therewith apparatus for use with said gun to provide for dispersement of a liquid by means of such high velocity gas, comprising:

a. holder means positioned on the bottom of said barrel of said gun near said exit end, b. a cylindrical liquid container, said container having a bottom liquid reservoir portion fabricated from a flexible, transparent material, and a top liquid discharge portion communicating with said reservoir, said top liquid discharge portion comprising a first collar means adapted to coact with and be rigidly held by said holder means, and second means comprising an outwardly extending arcuate arm with an aperture therein communicating at one end with said reservoir portion and at said other end with a tip portion of said arm, said aperture being of a substantially smaller diameter than said reservoir portion to permit said liquid to be drawn into said aperture by capillary action, said arcuate arm positioned by said collar and said holder means in a manner such that said tip of said arm is positioned in close proximity to said nozzle, with said cylindrical liquid container positioned beneath said high velocity air stream, whereby when high velocity gas is being emitted by said nozzle, said liquid is drawn from said reservoir and dispersed, said high velocity stream causing said liquid to be withdrawn from said reservoir due to said capillary action and the attendant compression of said flexible container, and c. a protective cylindrical cage adapted to surround said flexible bottom liquid reservoir portion, said cage fabricated from a rigid material and dimensioned to permit easy compression of said reservoir portion, while serving to prevent a user from inadvertently compressing the same to thereby discharge said liquid.
