Estimating the term…
A paint reservoir has a fluid outlet (115) connectable to a spray gun (101) and a fluid inlet (131) provided with a removable screw cap (132) whereby the fluid inlet (131) is directly accessible for introducing paint to the reservoir while attached to the spray gun (101). The fluid outlet (115) and fluid inlet (131) may both be provided in an end wall of the reservoir with outlet (115) located on the longitudinal axis of the reservoir or offset to allow the size of the fluid inlet (131) to be increased for easier filling of the reservoir. The outlet (115) can be aligned with the longitudinal axis of the reservoir or it can be inclined relative to the longitudinal axis to provide greater clearance for access to the fluid inlet (131) when the reservoir is attached to the spray gun (101).
Apparatus such as a spray gun for spraying a liquid comprising a collapsible reservoir for a liquid to be sprayed, a spray nozzle for dispensing liquid supplied from the reservoir, the reservoir having a fluid outlet connectable to the apparatus and a fluid inlet for adding liquid to the reservoir, and the fluid inlet having a removable closure for opening and closing the fluid inlet, wherein the closure is directly accessible when the reservoir is connected to the apparatus.
Apparatus according to claim-6 wherein the lid is separate from the flexible container and means is provided for securing the lid to close the opening in the container.
A spray gun for spraying paint-like materials comprising a spray nozzle for spraying a liquid, a collapsible reservoir for the liquid, the reservoir having a fluid outlet releasably connected to the spray gun whereby, after use, the reservoir can be detached and discarded, and the reservoir further having a fluid inlet arranged to be directly accessible when the reservoir is attached to the gun for adding liquid to the reservoir.
A reservoir for supplying a liquid to a spray gun or the like, the reservoir having a fluid outlet adapted for releasable connection to the spray gun and a fluid inlet directly accessible when the reservoir is attached to the spray gun for introducing liquid to the reservoir, wherein the reservoir is collapsible when liquid is withdrawn therefrom in use of the spray gun.
