(12) Referring now to FIG. 1, bottle assembly 100 includes body 102, it may include a top radius 104, a bottom radius 106, a thread lip 108, a cap body (“cap”) 110, a pressurizing plunger (“plunger”) 112, a teeter valve pivot 114, a nozzle base 116, an adjustable spray screw cap 118, and spray nozzle 120.

(13) In one or more embodiments, body 102 may have a threaded portion (not pictured here) upon which the cap 110 may be screwed onto. Plunger 112 is disposed through the cap 110 and is used to pressurize the body 102. Adjustable spray screw cap 118 is threaded onto nozzle base 116. By turning the adjustable spray screw cap 118, the position of spray nozzle 120 is modified within nozzle base 116 thus changing the characteristics of the spray. The spray is activated by depressing a teeter valve (not pictured here) which pivots on an axis transverse through the diameter of the cap 110 located at the teeter valve pivot 114.

(14) FIG. 2 depicts the assembled bottle assembly 100 and further depicts a cut-away portion 202 of the cap 110. The teeter valve 204 is shown located between the cap 110 and the plunger 112.

(15) Referring now to FIG. 3 which shows a exploded perspective view of the left side of the bottle assembly 100. Plunger shaft 302 has a top end which is connected to the plunger 112 and a bottom end which is connected to the stopper 304. The stopper 304 may contain at least one of a multiple of flanges to produce pressure within the body 102.

(16) The plunger shaft is disposed through an opening 306 in the teeter valve 204. The teeter valve 204 pivots on an axis through the cap 110 and located at the teeter valve pivot 114. This pivot is accomplished by a teeter valve flange 308 projecting down on the underside of the teeter valve 204. A pivot tab 310 is located at the lower tip of the teeter valve flange 308. This pivot tab 310 extends partially into the teeter valve pivot 114 in the cap 110.

(17) In one embodiment, the cap 110 is removably connected to the body 102 by a threaded portion 320 of the body and a mirror threaded portion (not pictured here) on the interior of the cap 110. To further seal this connection, a washer 312 is disposed between the body 102 and the cap 110.

(18) The stopper 304 is disposed within the pump shaft 316. The pump shaft 316 has two ends, an upper end which has a threaded portion 318 and a lower end (not pictured here). The threaded portion 318 of the pump shaft 316 is rotatably attached to the underside of the cap 110.

(19) A relief tube 314 has both a first (“upper”) end and a second (“lower”) end. Relief tube 314 allows the pressurized fluid to escape the body 102. In one embodiment, the upper end of relief tube 314 may be press-fit into the underside of the cap 110 utilizing an o-ring (not pictured) to form a seal.

(20) A flexible conduit 322 has both a first (“upper”) end and a second (“lower”) end. The lower end of flexible conduit 322 is connected to the relief tube 314. Pressurized fluid which rises through the relief tube 314, passes through the cap 110 and then, in one or more embodiments, the upper end of relief tube 314 may be barbed to connect to the flexible conduit 322. The upper end of the flexible conduit 322 passes through nozzle base 116 and is attached to the spray nozzle 120. In one or more embodiments, the spray nozzle may 120 may be barbed, and flexible conduit 322 is press-fit over the barbs to form a connection. The pressurized fluid, having entered the nozzle base 116, then attains the desired spray characteristics determined by the positioning of the adjustable spray screw cap 118 and the spray nozzle 120.

(21) Referring now to FIG. 4, a return spring 402, is disposed between the teeter valve 204 and the cap 110. When the teeter valve 204 is pressed to activate a spray discharge, return spring 402 is compressed and the teeter valve pivots on the pivot tab 310, located at the tip of the pivot flange 308. Return spring 402 is located on extrusion 404, on the interior top surface of cap 110.

(22) The plunger shaft 302 is disposed within a shaft guide 406 and when depressed and air is conducted through the pump shaft 316 and into the body 102 through a pump valve 410, creates a pressure is created within body 102. A relief tube extension 408 is connected to relief tube 314, which in turn is connected to the underside of the cap 110. In one embodiment, the relief tube extension 408 may be press-fit into the relief tube 314. A through hole 606 (not pictured here) in the cap 110 then connects the flexible conduit 322 to the relief tube 314. This relief extension 408, relief tube 314 and flexible conduit 322 then conduct the pressurized fluid to the nozzle base 116.

(23) FIG. 5 depicts the underside of the assembled pump and valve mechanism of one or more of the preferred embodiments. The interior threaded portion 502 of underside of the cap 110 is used to connect to and disconnect from the body 102 (not pictured here).

(24) Housing 504 contains the through hole 606 (not pictured here) for the relief tube 314 and is disposed on the underside of the cap 110, as is the threaded connector 506 for the pump shaft 316.

(25) Referring now to FIG. 6, cap 110 is viewed from the top with teeter valve 204 and plunger 112 removed for clarity. Detents 602 and 604 allow clearance and free movement for pivot flanges 308 on interior surface of cap 110.

(26) A through hole 606 provides a connection point for the lower end of flexible conduit 322. Flexible conduit 322 is then routed across the upper interior surface of cap 110 by guides 608 and 610. The upper end of flexible conduit 322 is then connected to the barbed nozzle base 116 (not pictured here).

(27) Referring now to FIG. 7, the cap insert assembly 700 comprises the interior threaded portion 502 of underside of the cap 110 which is used to connect to and disconnect from the body 102 (not pictured here). Housing 504 contains the through hole 606 (not pictured here) for the relief tube 314 and is disposed on the underside of the cap 110, as is the threaded connector 506 for the pump shaft 316. Filter assembly 702 is removably attached to the relief tube extension 408.

(28) Referring now to FIG. 8, uptake adapter assembly 800 is comprised of a first end and a second end. Upper flanges 802 are disposed at the first end of the uptake adapter 800 and inserted into relief tube 314 (not pictured). A first hose seat 804 and a second hose seat 806 are positioned adjacent to each other. An intake indention 808 is positioned adjacent to the second hose seat 806. An intake hole 810 is centered within the intake indention 808. Lower flange 812 is disposed at the second end of the uptake adapter 800 and inserted into relief tube extension 408 (not pictured).

(29) Referring now to FIG. 9a, cap insert assembly 700 is shown as an isometric view with a detailed inset.

(30) Referring now to FIG. 9b, the detailed inset of FIG. 9a illustrates the positioning of the uptake adapter assembly 800 between the relief tube 314 and the relief tube extension 408.
