IV. DESCRIPTION OF THE PREFERRED EMBODIMENT

(9) A universal pressurized spray adapter 10 for a liquid bottle, shown in FIGS. 1-7, replaces a factory pump trigger spray nozzle to provide for pressurization of the bottle and its liquid contents for release of a pressurized flow of the liquid contained in the bottle.

(10) The spray adapter 10 comprises a dual threaded transition member 20, FIG. 7, having a lower end 22 defining outer threads 30 which are applied to a selected bottle cap adapter 32 to an outer threaded neck of a bottle, with the bottle cap adapter 32 provided in various inner diameters to adapt to bottle neck of a variety of sized bottles. The lower end 22, FIG. 7 further comprises a lower surface 24 defining a lower draw stem port 33 and a lower pressure tube outlet port 34, each port defining the entry of a respective draw stem channel 40 and a pressure tube channel 45. The draw stem channel 40 secures an upper end 52 of a hollow draw stem 50, FIG. 1, which is provided in a variety of lengths, with the appropriate selected draw stem 50 dependant upon the depth of the bottle to which the spray adapter 10 is applied. The pressure tube channel 45 receives an outer perimeter surface 83 of a hollow outer plunger tube 82 of a plunger tube assembly 80, FIGS. 1 and 5, which forms an airtight seal between the lower pressure tube outlet port 34, FIG. 7, and the outer perimeter surface 83 of the outer plunger tube 82. The dual threaded transition member further comprises an upper end 26 defining outer threads 36 and an upper surface 28 defining a spray nozzle outlet port 37, which integrates with the draw stem channel 40 and a plunger assembly inlet port 38 integrating with the pressure tube channel 45. The plunger tube assembly 80, as shown in FIG. 1, therefore penetrates through the pressure tube channel 45 and further seals the plunger tube assembly 80 within the plunger assembly inlet port 38.

(11) The spray adapter 10 further comprises a spray nozzle assembly 60 further defining a spray nozzle uptake tube 62 which engages and secures within the spray nozzle outlet port 37 and connects through the draw stem channel 40 with the draw stem 50 to supply liquid content of the bottle to the spray nozzle assembly 60 under pressure created by the pressurization of the bottle contents by the involvement of the plunger tube assembly 80. The spray nozzle uptake tube 62 transfers the pressurized liquid content into the spray nozzle release tip 63 upon activation by pressing the pressure release button 64, which opens the nozzle release tip 63 to allow the liquid content to exit an adjustable spray nozzle housing 65 under pressure. The spray nozzle housing 65 is engaged over the spray nozzle tip 63, with the spray nozzle tip 63 moving forward and backward within the spray nozzle housing 65 between an open and closed position. The pressure release button 64 is connected to the nozzle release tip 63 by a pivotal release lever 66 which withdraws a release lever arm 67, the pivotal release lever 66 and release lever arm 67 attaching between the pressure release button 64 and the nozzle release tip 63, as shown in FIGS. 2-3. The entire spray nozzle assembly 60 is encased between a left section encasement 70, FIG. 1, and right section encasement 74, FIG. 6. The pivotal release lever 66 is pivotally mounted within the left section encasement 70, which may be reversed to be contained within the right section encasement 74, wherein the pressure release button 64 is depressed, the pivotal release lever 66 pivotally withdraws the release lever arm 67, extending the spray nozzle release tip 63 and releasing the liquid through the hollow draw stem 50 into the uptake tube 62 through the nozzle housing 65 directed at an intended target where the liquid content is to be disbursed. The upper end 26 of the dual threaded transition member 20 receives opposing mated inner threads 72, 76, of the left section member 70 and right section member 74 joined together to enclose the spray nozzle assembly 60, with the facing inner threads 72, 76, of the left section member 70 and right section member 74 forming an inner threaded cylinder 78 which engage the outer threads 36 of the upper end 26 of the dual threaded transition member 20, securing the spray nozzle assembly 60 to the dual threaded transition member 20, the dual threaded transition member 20 further secured to the bottle by the appropriate selected bottle cap adapter 32, extending the appropriate selected draw stem 50 into the bottle and the liquid contents contained within the bottle.

(12) Once the spray adapter 10 is secured upon the bottle, the plunger tube assembly 80, FIGS. 4-5, is utilized to pressurize the bottle. The plunger tube assembly 80 further comprises the hollow outer plunger tube 82, which engages the pressure tube channel 45 through the dual threaded transition member 20, with a lower end 85 of a plunger rod 84 inserted within the hollow outer plunger tube 82 with a plunger expansion 86 terminating at the lower end 85 of the plunger rod 84, the plunger expansion 86 forming an air tight seal between the plunger expansion 86 and the hollow outer plunger tube 82, drawing air from outside the spray adapter 10 and forcing it into the bottle each time the plunger rod 84 is raised and lowered, in a pumping motion. The plunger expansion 86 prevents an outflow of the air into the bottle, but causes the inflow of air into the bottle, thereby creating the pressure required to operate the spray adapter 10. The plunger rod 84 further defines an upper end 87 with an upper plunger knob 88, FIGS. 1 and 4-5, to lift and press the plunger rod 84 to pressurize the bottle contents.

(13) Optionally, the spray nozzle housing 65 may provide and adjustable spray pattern, not shown, but contemplated within the scope of the invention. In addition, the spray nozzle assembly 60 may use some means other than the pressure release button 64, which may be supplied as a lever, a trigger, or other means which can be pressed, pulled or otherwise manipulated to activate the movement of the spray nozzle release tip 63.

(14) While the universal pressurized spray adapter 10 has been particularly shown and described with reference to a preferred embodiment thereof, it will be understood by those skilled in the art that changes in form and detail may be made therein without departing from the spirit and scope of the invention.
