  • Patent number: 11992855
    Abstract: The present invention relates to a fluid delivery assembly for a spraying apparatus. The assembly comprises an outer cup, a lid having a fluid outlet adapted to couple the lid to the spraying apparatus, and a liner for holding paint. The fluid delivery assembly comprises an interlocking keyed geometry adapted to prevent rotation of at least one of the lid and the liner with respect to the cup. The interlocking keyed geometry comprises at least one of (a) at least one protrusion of the cup extending into at least one recess of the lid, and (b) at least one protrusion of the lid extending into at least one recess of the cup, wherein the liner is trapped between the protrusion and the recess. The invention also relates to liners for such fluid delivery assemblies, which may be provided as a set of liners having different inners volumes.

  • Publication number: 20220401978
    Abstract: 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.

  • Publication number: 20220347703
    Abstract: Spray gun reservoir components are disclosed. The spray gun reservoir component includes a liquid outlet and an outer face, and defines a centerline plane and an attachment plane. The liquid outlet surrounds a longitudinal axis. The outer face extends away from the liquid outlet. The centerline plane passes through the longitudinal axis. The attachment plane is defined orthogonally to the longitudinal axis and the centerline plane. The outer face further comprises a retention feature extending away from the centerline plane and generally parallel to the attachment plane. In some embodiments, the spray gun reservoir component further comprises a bearing surface formed on the outer face along the attachment plane to engage with a corresponding bearing surface on a liquid spray gun attachment point, with the bearing surface comprising the retention feature.
