A wash-free air-guiding cover includes a cover having a body with a fixing seat disposed on a side thereof. A ventilation tube is disposed on the fixing seat and includes a ventilation hole intercommunicated with the other side of the body. An air guiding device is mounted to the fixing seat and includes a tube having first, second, and third air guiding spaces. The air guiding device further includes first and second sealing members and first and second flow guiding rods. Air flowing into the tube must flow zigzag through the first, second, and third air guiding spaces and between the first and second flow guiding rods and the second and third air guiding spaces, assuring smooth flow of air during the painting operation and avoiding the paint from leaking via the ventilation tube and the ventilation hole of the cover.

A spray gun cup receptacle is disclosed comprising an open end for receiving a liner within a cavity and a base end opposite the open end. The sidewall comprises two apertures through which the cavity is visible from outside the spray gun cup receptacle. Also disclosed are improved lids for spray gun cups, and improved connections between the lid(s) and spray gun cup receptacles.

A connector system for a liquid container system for a spray gun includes a lid that includes a liquid outlet and an adapter. The adapter includes a spray gun end and a lid end. The ends are connected with a liquid-tight passageway. Further, the spray gun end is adapted for releasable engagement with a liquid inlet port of the spray gun and the lid end is adapted for releasable engagement with the liquid outlet. The connector system also includes a plurality of interlocking tab assemblies for releasably attaching the adapter to the lid. Each assembly includes a first tab and a second tab, wherein an end of the first tab is adapted to secure the adapter to the lid when the first tab and the second tab are interlocked.

Fluid liners and container assemblies for a spraying apparatus and related methods of use are provided. The disclosed liners include a side wall defining a fluid-containing portion and an open end, a flange extending outwardly from the side wall, and a latching member coupled to the flange, where the latching member includes a retaining feature for releasably coupling the side wall to a lid compatible with the liner. Disclosed fluid containers include a lid having a fluid outlet adapted to couple the lid to the spraying apparatus and a collapsible liner, where either the liner or lid comprises a latch that releasably couples the liner and the lid to each other. Advantageously, the fluid liners and fluid containers can provide enhanced storage options for container contents between spraying operations.

Vent assemblies for reservoirs and other closed systems. The vent assemblies include one or more apertures in a wall of the reservoir. A closure member is retained on the external surface of the reservoir by a closure member retainer and includes a first component and a second component, the second component is relatively conformable compared to the first component. The second component is positioned between the first component and the wall of the reservoir. A sealing surface is located on either the first component or the second component, where the sealing surface closes the aperture when the closure member is in an unvented position, and the sealing surface does not close the aperture when the closure member is in a vented position.

An improved multi-purpose sprayer for separately dispensing a first liquid product and a mixture with a spray head body is presented. The multi-purpose sprayer is operable by manually operating an actuator in a first flow position for selecting the flow of a first liquid product and a second flow position for selecting the flow of the first liquid product and the mixture.

Retaining bracket for a fluid spray delivery apparatus to ensure that an applicator rod remains properly attached to the apparatus and in fluid communication with the fluid even when subjected to a driving force. Also disclosed is a fluid application system or assembly, and a method of applying fluid using the same, the system or assembly including a source of fluid to be applied to a target object, a siphon gun assembly, an applicator rod, tubing for placing the applicator rod in fluid communication with the siphon gun assembly, and a retaining bracket that secures the tubing to the siphon gun assembly such that the tubing remains in place and does not disconnect from the siphon gun assembly when subjected to a driving force such as water under pressure.

Fluid liners and container assemblies for a spraying apparatus and related methods of use are provided. The disclosed liners include a side wall defining a fluid-containing portion and an open end, a flange extending outwardly from the side wall, and a latching member coupled to the flange, where the latching member includes a retaining feature for releasably coupling the side wall to a lid compatible with the liner. Disclosed fluid containers include a lid having a fluid outlet adapted to couple the lid to the spraying apparatus and a collapsible liner, where either the liner or lid comprises a latch that releasably couples the liner and the lid to each other. Advantageously, the fluid liners and fluid containers can provide enhanced storage options for container contents between spraying operations.

Disclosed is a foldable cup and a spray cup, comprising: a cup opening, a cup body connected with the cup opening, and a discharge port disposed at the lower portion of the cup body, wherein the cup body is made of a flexible material, which, after being folded, shrinks the overall cup size. The disclosed cup body is made of a foldable, flexible material, such that the cup size can be shrunk to facilitate storage.

A back-mounted spray apparatus includes a storage container shaped to receive therein liquid to be sprayed. The storage container includes a pair of side handles integrally formed therewith and a central handle therebetween and integrally formed therewith. Actuation of a spraying assembly of the apparatus causes the liquid from the storage container to be selectively sprayed outwards therefrom.

The storage container has a lower or front peripheral portion that is arc-shaped in a direction extending between sides thereof according to one aspect. The backpack sprayer includes a frame member extending along a rear thereof and to which the storage container couples. The frame member has an aperture extending therethrough which is arc-shaped.

A horizontal frame member is cantilevered from a vertical frame member according to another aspect. The storage container has a lower portion within an inwardly-facing channel shaped to receive and couple to the horizontal frame member.
