Abstract

A tank sprayer assembly includes a tank component and a subassembly, the tank component having a neck that defines a first access opening. The subassembly includes a sprayer component and a packaging container, the packaging container defining a cavity and having a lower wall defining a second access opening. The sprayer component includes a cap and a pump attached to the cap, the cap and the neck being configured to threadingly engage each other. The tank sprayer is positionable in an assembled configuration and disassembled configuration. In the assembled configuration, the cap is aligned with the second access opening, the neck is extended through the second access opening into the cavity, and the neck and the cap are threadingly engaged to secure the sprayer component to the tank component. In the disassembled configuration, the cap is aligned with the second access opening and the neck is spaced apart from the cavity.

Dependent claims

A tank sprayer assembly, comprising:

a tank component defining a chamber configured to receive fluid therein, said tank component including a neck defining a first access opening configured to allow access to said chamber, and said neck having an externally threaded portion;
and
a subassembly including:
a packaging container having an upper wall, a lower wall, and a plurality of side walls, the upper wall and the lower wall being spaced apart from each other to define a cavity therebetween, the plurality of side walls extending between the upper and lower walls surrounding the cavity, the lower wall defining a second access opening configured to allow access to said cavity, and
a sprayer component including (i) a cap defining a cap space and having a skirt that includes an internally threaded portion facing said cap space, and (ii) a pump attached to said cap and including a cylinder and a piston movably positioned within said cylinder, the cap being retained within the cavity with the skirt held against the lower wall around the second access opening by the upper wall and with the pump extending from the cap through said second access opening,
wherein said tank sprayer is positionable in an assembled configuration and disassembled configuration,
wherein, when said tank sprayer is positioned in said assembled configuration, (i) said internally threaded portion of said cap is aligned with said second access opening of said lower wall, (ii) said neck extends through said second access opening of said lower wall so as to be at least partially positioned within said cavity, and (iii) said externally threaded portion of said neck is meshingly engaged with said internally threaded portion of said skirt of said cap so as to secure said sprayer component to said tank component, and
wherein, when said tank sprayer is positioned in said disassembled configuration, said neck is spaced apart from said cavity of said packaging container.

5 more elements

A method of assembling a tank sprayer assembly, comprising:

retaining a cap of a sprayer component within a packaging container to form a subassembly, the packaging container having an upper wall, a lower wall, and a plurality of side walls, the upper wall and the lower wall being spaced apart from each other to define a cavity therebetween, the plurality of side walls extending between the upper and lower walls surrounding the cavity, the lower wall defining an access opening to said cavity, the cap being retained against the lower wall over the access opening by the upper wall, the sprayer component including a pump attached to said cap, the pump extending from said cap through said access opening;
advancing a neck of a tank component through the first access opening and into engagement with an internally threaded portion of the cap within the cavity of the packaging container of the subassembly;
and
rotating the tank component in relation to the subassembly while the neck is located in the cavity so as to meshingly engage an externally threaded portion of the neck with the internally threaded portion of the cap so as to couple the subassembly to the tank component.

A subassembly of a tank sprayer assembly, comprising:

a packaging container having an upper wall, a lower wall, and a plurality of side walls, the upper wall and the lower wall being spaced apart from each other to define a cavity therebetween, the plurality of side walls extending between the upper and lower walls surrounding the cavity, the lower wall defining an access opening configured to allow access to said cavity, and
a sprayer component including (i) a cap defining a cap space and having a skirt that includes an internally threaded portion facing said cap space, and (ii) a pump attached to said cap and including a cylinder and a piston movably positioned within said cylinder, both said cylinder and said piston extending through said cap space,
wherein the cap is retained within the cavity against the lower wall over the access opening by the upper wall with said internally threaded portion aligned with said access opening, and
wherein both said cylinder and said piston extend from said cavity of said packaging container through said access opening.
