Abstract
Disposable reservoirs for use with spray apparatuses, reservoir-adapter kits, spray assemblies employing such reservoirs, and methods of use are disclosed.
Description
- This invention relates to disposable reservoirs for holding liquids, and spray assemblies and methods employing such reservoirs.
- A wide variety of spray apparatuses for applying liquids, such as paint, varnish, cleaning solvents, or other liquid materials to a surface are known. Typically, such spray apparatuses includes a reservoir containing the liquid and a spray apparatus configured to spray the liquid in the reservoir. The liquid from the reservoir may be gravity fed or pressure fed to the spray apparatus by an air bleed from the compressed air line to the reservoir.
- One conventional reservoir is a rigid pot attached to the spray gun apparatus with a removable lid. The reservoir is re-usable and should be thoroughly cleaned when changing the liquid in the reservoir in order to prevent contaminating the new liquid that is poured into the reservoir. However, cleaning the reservoir and, if needed, the spray gun apparatus is time consuming and may require the use of solvents that are costly and may be a health hazard to the operator.
- Another conventional reservoir employs a collapsible liner that is placed within a rigid reservoir. During use, the liquid is withdrawn from the collapsible liner and, after spraying, the collapsed liner and lid can be removed and thrown away allowing a new, clean liner and lid to be used for applying a different liquid. While the collapsible liner is useful because the rigid reservoir does not have to be cleaned as often, it can be difficult to install and remove the liner within the rigid reservoir. Furthermore, sometimes not all of the paint in the liner is used, and this un-used paint can be difficult to recover from the liner.
- Therefore, there is a need in the art for a more user friendly disposable reservoir. It would also be desirable that such a reservoir be cheap to fabricate and suitable for use with a variety of conventional spray gun apparatuses.
- The invention is directed to disposable reservoirs for use with spray apparatuses, reservoir-adapter kits, spray assemblies employing such reservoirs, and methods of use. In one aspect of the invention, a disposable reservoir for holding a liquid, such as paint, includes a body with a first portion having an outlet and a threaded portion configured to be threadly coupled to a spray apparatus and, a second portion having an inlet. A passageway or hollow within the body extends between the inlet and the outlet. The reservoir further includes a lid removably attachable to the second portion to cover the inlet.
- Another aspect of the invention is directed to a reservoir-adapter kit for use with a spray apparatus. The kit includes at least one adapter having a passageway therethrough, a reservoir coupling portion, and a spray apparatus coupling portion configured to be threadly coupled to the spray apparatus. The kit further includes at least one reservoir having a body with a first portion having an outlet and a second portion having an inlet. A passageway or hollow within the body extends between the inlet and the outlet. The first portion of the body also has a threaded portion configured to be threadly coupled to the reservoir coupling portion of the at least one adapter so that the inlet of the at least one adapter is in fluid communication with the outlet of the body. The kit further includes a lid configured to be removably attached to the second portion to cover the inlet. The kit may include a plurality of reservoirs of different sizes and configurations and a plurality of adapters to enable the reservoirs to be used with various types of spray apparatuses.
- Another aspect of the invention is directed to a spray assembly. The spray assembly includes a reservoir having a body with a first portion having an outlet and a threaded portion, a second portion having an inlet, and a passageway or hollow within the body extending between the inlet and the outlet. The reservoir further includes a lid removably attached to the second portion to cover the inlet. The spray assembly also includes a spray apparatus operable to spray fluid disposed within the reservoir. The spray apparatus includes a threaded coupling member coupled to the reservoir so that the outlet of the reservoir fluidly communicates with the spray apparatus.
- Yet another aspect of the invention is directed to a method of using a spray apparatus. The method includes providing a reservoir. The reservoir includes a body with a first portion having an outlet and a threaded portion, a second portion having an inlet, and a passageway or hollow within the body extending between the inlet and the outlet. The reservoir and a threaded coupling portion of the spray apparatus are coupled to each other. The reservoir is filled with liquid. The liquid is sprayed onto a surface using the spray apparatus. After spraying, the reservoir may be de-coupled from the spray apparatus, and the reservoir may be thrown away.
