Abstract
A liner system for a spray gun including three liners, one of which resides within the interior of a spray gun reservoir, a second of which rides on an outside of the reservoir, a third of which is interposed between the reservoir and attached to a spray head via bayonet hook and has a free end which serves as a shield when placed over the spray head, just upstream from the nozzle. These liners minimize down time when cleaning spray guns and reduce the amount of solvent required.
Claims17
A disposable liner for spray guns wherein the spray gun is of the type having a fluid reservoir and a separable spray head, comprising, in combination:
- a first liner having an external configuration complemental to interior walls of the reservoir, placed in the reservoir and including an opening at the top of said liner,
- and means to secure said liner to the reservoir, whereby the fluid normally stored in the reservoir resides in said liner to reduce both time in cleaning the spray gun and volume of cleaning solvent,
- and, including a second liner having an internal configuration complemental to exterior side walls of the reservoir and placed over the reservoir to reduce both time in cleaning the spray gun and volume of cleaning solvent.
A kit for minimizing both spray gun cleaning down time and the volume of solvent required, the kit comprising:
- three liners, a first liner which lines an interior of a spray gun reservoir,
- a second liner which circumscribes the reservoir's outer periphery, a third liner which both shields a spray head and serves as a gasket between the reservoir and the spray head.
A method for using a spray gun, the steps including:
- opening the gun to expose the interior of the gun's reservoir,
- inserting a first liner into the reservoir,
- inserting a second liner about the reservoir before inserting the first liner,
- turning over a top edge of the first liner to align with bayonet pins on the reservoir, locking the liner to the gun,
- filling the first liner with fluid,
- closing the gun, and
- spraying.
