Abstract
A handheld fluid sprayer (10) is configured to draw spray fluid from a reservoir (14) mounted on the fluid sprayer and eject the spray fluid through a nozzle (32). The reservoir is removably mounted to the fluid sprayer. A filling apparatus can connect to the reservoir at the same interfaced that the reservoir (14) connects to the fluid sprayer (10). The filling apparatus can be used to refill the reservoir (14).
Claims19
A spray system comprising:
- a sprayer having a body and a pump configured to pump spray fluid to a spray tip;
- a reservoir mountable to the sprayer by a first interface formed between a reservoir mount of the reservoir and a sprayer mount of the sprayer, wherein the reservoir mount extends around an opening that is open to an interior of the reservoir, wherein the reservoir mount is configured to connect to the sprayer mount such that the sprayer supports the reservoir by the sprayer mount connecting to the reservoir mount;
- and
- a filling device mountable to the reservoir by a second interface formed between the reservoir mount and a fill mount, wherein the filling device includes a funnel having the fill mount and configured to route fluid to the reservoir through the opening, wherein the fill mount and the reservoir mount are configured to connect together such that the reservoir is connected to the filling device to move with the filling device.

A method of filling a reservoir for a handheld fluid sprayer, the method comprising:
- connecting a filling device to a reservoir by a first interface between a fill mount formed on a funnel of the filling device and a reservoir mount formed on the reservoir such that the reservoir is directly connected to the filling device;
- pouring spray fluid into the funnel, the funnel directing the spray fluid to the reservoir through the first interface;
- draining excess spray fluid from the funnel by pouring spray fluid out of the funnel while the reservoir remains connected to the filling device by connection between the fill mount and the reservoir mount;
- disconnecting the filling device from the reservoir by breaking the first interface;
- and
- connecting the reservoir to the handheld fluid sprayer by interfacing the reservoir mount and a sprayer mount of the handheld fluid sprayer, the reservoir mount connected to the sprayer mount such that the reservoir is supported by the handheld fluid sprayer to be carried with the handheld fluid sprayer.
