• This invention relates to the field of tank sprayers, and more particularly to a tank sprayer assembly including a tank component and a sprayer package subassembly.
• Tank sprayer assemblies are often utilized to dispense low viscosity fluids.
• the assemblies typically include a tank component that is configured to hold a quantity of fluid to be sprayed.
• a hand pump is coupled to the tank component and is configured to introduce air into the tank component so as to pressurize the fluid therein.
• a hand sprayer is also coupled to the tank component and is utilized to disperse the pressurized fluid from the tank component.

• a tank sprayer assembly 10 in accordance with the present disclosure comprises a tank component 14 and a sprayer package subassembly 18.
• the sprayer package subassembly includes a package container 72 and sprayer component 30 (see, e.g., FIGS. 2 and 3) for use with the tank component 14.
• the package container 72 of the sprayer package subassembly 18 is configured to retain, support, and protect various parts and mechanisms of the sprayer component 30 in an assembled state to facilitate handling, shipping, and storing of the sprayer package subassembly 18 as a separate unit from the tank component 14.
• the package container 72 also retains the sprayer package subassembly 18 in a manner that enables the sprayer package subassembly 18 to be readily assembled to the tank component 14.
• the sprayer package subassembly 18 is configured to be assembled to the tank component 14 without requiring removal of the sprayer component 30 from the package container 72. (see, e.g., FIG. 2).
• the lower wall 76 includes a rim structure 80 that surrounds the access opening 78.
• the rim structure 80 includes a recess or depression that defines a substantially horizontal surface 81, also referred to as seating surface 81, and a substantially vertical surface 83, also referred to as boundary surface 83.
• the seating surface 81 of the rim structure serves as a surface against which the skirt portion 38 of the cap 32 is placed when the cap 32 secured within the cavity 74.
• the vertical surface 83 extends from the seating surface 81 to form a receptacle structure in which the lower end portion of the skirt portion 38 is received.
• the upper wall 84 forms a barrier on an opposite side of the cavity 74 from the lower wall 76.
• the upper wall 84 is configured to be movable in relation to the other walls to enable the sprayer component 30 to be advanced into the cavity 74 and the skirt portion 38 of the cap 32 to be placed in engagement with the seating surface 81 of the rim structure 80. Once the sprayer component 30 is positioned in the cavity 74, the upper wall 84 is moved back to its position shown in FIGS. 5-8 to secure the cap 32 within the cavity. When the cap 32 is positioned within the cavity 74 with the cap 32 aligned with the access opening 78, the uptake tube 44 and the pump cylinder 64 extend through the access opening 78 to be located partially exterior to the cavity as depicted in FIG. 5 and 8. As depicted in FIG.
