Definitions

  • the present disclosure relates to liquid spraying apparatuses, such as spray guns. More particularly, it relates to reservoir systems used to contain and supply liquid to a spray gun.
  • Liquid spray guns are commonly used to spray coating such as stains, primers, paints, sealers and the like onto surfaces.
  • spray guns are widely used in vehicle body repair shops when re-spraying a vehicle that has been repaired following an accident.
  • the liquid is contained in a reservoir or cup attached to the gun from where it is fed to a spray nozzle.
  • the liquid may be gravity fed or suction fed or, more recently, pressure fed by an air bleed line to the reservoir from the compressed air line to the spray gun, or from the spray gun itself.
  • WO 2004/037433 A1 discloses a spray gun reservoir system according to the prior art.
  • the liquid is contained in a rigid reservoir or pot removably mounted on the spray gun. In this way, the pot can be removed for cleaning or replacement.
  • the pot was secured to the gun empty and provided with a removable lid by which the desired liquid could be added to the pot while attached to the gun. On completion of spraying, the pot can be removed and the gun and pot cleaned for re-use.
  • the PPS TM Paint Preparation System available from 3M Company of St. Paul, MN provides a reservoir that eliminates the need for traditional mixing cups and paint strainers.
  • the PPS TM Paint Preparation System reservoir includes a reusable outer container or cup, an open-topped liner, a collar and a lid.
  • the liner is a close fit in the outer container, and paint (or other liquid) that is to be sprayed is contained within the liner.
  • the lid is assembled to the liner and provides a spout or conduit through which the contained paint is conveyed.
  • the liner collapses as paint is withdrawn and, after spraying, the liner and lid can be removed allowing a new, clean liner and lid to be employed for the next use of the spray gun.
  • the amount of cleaning required is considerably reduced and the spray gun can be readily adapted to apply different paints (or other sprayable coatings) in a simple manner.
  • the PPS TM Paint Preparation System is one example of a reservoir system used to contain and supply liquid to a spray gun.
  • reservoir systems can include one, two or more components that may or may not be directly employed for a particular application.
  • the reservoir or pot incorporates one or more connection features that facilitate removable assembly or attachment to the spray gun.
  • the spray gun and reservoir are designed in tandem, providing complementary connection formats that promote direct assembly of the reservoir to the spray gun.
  • the corresponding reservoir system will include an adaptor that is employed between the reservoir and spray gun.
  • the adaptor has a first connection format at one end compatible with the spray gun inlet and a second connection format at an opposite end compatible with the reservoir outlet. With either approach, releasable connection between the spray gun and reservoir was conventionally achieved via a standard screw thread connection format.
  • any improvements to the adaptor or connector formats are desirable.
  • users desire improvements to other components of the reservoir system, either alone or in combination with one another.
  • the cup receptacle, the lid, connection between the lid and cup receptacle, along with auxiliary components intended to be used apart from the spray gun are all subject to potential improvement.
  • the inventors of the present disclosure recognized that a need exists for spray gun reservoir systems that overcome one or more of the above-mentioned problems.
  • the lid includes a lid body comprising a spout, a platform and a wall.
  • the platform at least partially surrounds the spout, and defines a major plane and a partial helical shape.
  • the partial helical shape declines with respect to the major plane and revolves about a central axis of the spout.
  • the wall includes an outer face adjoining the platform and including a portion that declines with respect to the major plane of the platform.
  • the partial helical shape interrupts the declining portion of the outer face of the wall.
  • the outer face of the wall comprises a dome shape or a conical shape.
  • a first end of the partial helical shape is proximate a transition zone to the major plane and a second end of the partial helical shape interrupts the declining portion of the outer face of the wall.
  • the lid includes a lid body and a collar.
  • the lid body provides a spout and a platform surrounding the spout. At least a portion of the platform forms a partial helical shape revolving about a central axis of the spout.
  • the collar is rotatably connected to the lid body. Further, the collar includes a lid connector structure configured to connect the lid to the cup receptacle.
  • the lid includes a collar.
  • the collar is rotatably connected to the lid body.
  • the collar includes a lid connector structure configured to connect the lid to the cup receptacle.
  • the cup receptacle includes a side wall forming an aperture for viewing contents of an inner cavity, and the aperture has a non-uniform circumferential width.
  • the lid body includes an outer face defining a continuous dome shape, and the platform defines a ramp surface projecting into the dome shape.
  • the reservoir system further includes an adaptor configured to connect the reservoir with a spray gun inlet port.
  • the lid and the adaptor provide complementary connection formats.
  • the reservoir system further includes a plug for sealing the spout.
  • the plug can include a plug side wall with a stepped outer diameter.
  • the reservoir system further includes a shaker core useful, for example, in mounting the reservoir to a shaker machine.
  • the shaker core can define opposing, first and second ends, with an inner diameter of the shaker core at the first end being less than a diameter of the shaker core at the second end.
  • liquid refers to all forms of flowable material that can be applied to a surface using a spray gun (whether or not they are intended to color the surface) including (without limitation) paints, primers, base coats, lacquers, varnishes and similar paint-like materials as well as other materials, such as adhesives, sealer, fillers, putties, powder coatings, blasting powders, abrasive slurries, mold release agents and foundry dressings which may be applied in atomized or non-atomized form depending on the properties and/or the intended application of the material and the term "liquid" is to be construed accordingly.
  • FIG. 1 depicts one embodiment of a spray gun assembly 20 including a reservoir system 30 in accordance with principles of the present disclosure assembled to a spray gun 32 of a gravity-feed type.
  • the gun 32 can assume a wide variety of forms, and generally includes a body 34, a handle 36, and a spray nozzle 38 at a front end of the body 34.
  • the gun 32 is manually operated by a trigger 40 that is pivotally mounted on the sides of the body 34.
  • An inlet port 42 (referenced generally) is formed in or carried by the body 34, and is configured to establish a fluid connection between an interior spray conduit (hidden) of the spray gun 32 and a reservoir 44 (referenced generally) of the reservoir system 30.
  • the reservoir 44 contains liquid (e.g., paint) to be sprayed, and is connected to the inlet port 42 (it being understood that the connection implicated by the drawing of FIG. 1 does not necessarily reflect the connections of the present disclosure).
  • the spray gun 32 is connected via a connector 46 at a lower end of the handle 36 to a source of compressed air (not shown). Compressed air is delivered through the gun 32 when the user pulls on the trigger 40 and paint is delivered under gravity from the reservoir 44 through the spray gun 32 to the nozzle 38.
  • the paint or other liquid
  • FIG. 2 illustrates one non-limiting example of a reservoir system 50 in accordance with principles of the present disclosure.

  • One or more additional, optional components can be included with reservoir systems of the present disclosure as described below.
  • the reservoir 52 includes a cup receptacle 60 and a lid 62.
  • the reservoir 52 can further include a liner 64.
  • the liner 64 corresponds in shape to (and is a close fit in) an interior of the cup receptacle 60 and can have a narrow rim 66 at the open end which sits on the top edge of the cup receptacle 60.
  • the lid 62 includes a flange or collar 68 and a lid body 70.
  • the lid body 70 is configured to push-fit in the open end of the liner 64 to locate the peripheral edge of the lid body 70 over the rim 66 of the liner 64.
  • the lid/liner assembly is secured in place by the collar 68 that releasably engages the cup receptacle 60 as described below.
  • the lid 62 forms a liquid outlet or spout 72 (referenced generally) through which liquid contained by the liner 64 can flow.
  • the liner 64 collapses in an axial direction toward the lid 62 as paint is withdrawn from the reservoir 52. Air may enter the cup receptacle 60 as the liner 64 collapses (e.g., via an optional vent hole (hidden) in a base of the cup receptacle 60, one or more openings in a side wall of the cup receptacle 60, etc.).
  • the reservoir 52 can be detached from the spray gun 32 ( FIG. 1 ), the collar 68 released and the lid/liner assembly removed from the cup receptacle 60.
  • the cup receptacle 60 is left clean and ready for re-use with a fresh lid 62 and liner 64. In this way, excessive cleaning of the reservoir 52 can be avoided.
  • the adaptor 54 facilitates connection of the reservoir 52 to the spray gun inlet port 42 ( FIG. 1 ) as described in greater detail below.
  • the lid 62 provides a first connection format 74 (referenced generally) configured to releasably connect with a complementary second connection format 76 (referenced generally) provided with the adaptor 54, with the adaptor 54 further including a spray gun interface feature configured for connection to the spray gun inlet port 42.
  • the cup receptacle 60 is shown in greater detail in FIG. 3 .
  • the cup receptacle 60 includes an annular sidewall 80 defining an inner cavity 82.
  • the sidewall 80 terminates at an open end 84 providing access to the inner cavity 82.
  • Opposite the open end 84 is a base end 86.
  • a floor 88 extends radially inwardly from the sidewall 80 proximate the base end 86, and has a ring-like shape defining an opening 90.
  • the opening 90 can serve as a vent hole for the reservoir 52 ( FIG. 2 ) during use.
  • the floor 88 serves as or provides a support for the liner 64 ( FIG. 2 ).
  • the floor 88 can be slightly off-set from the base end 86 as shown, with the base end 86 enabling the cup receptacle 60 to be stably rested directly on a flat working surface.
  • one or more notches 92 can be defined in the sidewall 80 and open at the base end 86, effectively forming the based end 86 as a plurality of circumferentially separated feet that promote stable placement on a flat working surface.
  • At least one aperture or window 100 is formed through a thickness of the sidewall 80 to permit the contents of the cavity 82 to be viewed therethrough.
  • the aperture 100 can have a non-uniform or varying circumferential width.
  • a perimeter of the aperture 100 can be described as defining a first side 102 opposite a second side 104.
  • the first side 102 is proximate, but longitudinally spaced from, the base end 86; the second side 104 is proximate, but longitudinally spaced from, the open end 84.
  • Longitudinal extension of the aperture 100 can be viewed as defining a first section 106 extending from the first side 102, and a second section 108 extending from the first section 106 to the second side 104.
  • a width (or circumferential width) aperture 100 along the first section 106 is greater than a width of the aperture 100 along the second section 108.
  • the larger area first section 106 can also be appropriately sized for passage of a user's finger(s), such as to grasp the liner 64 ( FIG. 2 ) when attempting to disassemble the lid 62 ( FIG.
  • the smaller area second section 108 also affords a user the ability to discern a level of liquid is in the cavity 82 when the cup receptacle 60 is inverted (e.g., such as when connected to a spray gun) but with minimal impact on a structural integrity of the cup receptacle 60.
  • the second side 104 is spaced from the open end 84, such that the sidewall 80 is circumferentially continuous and uninterrupted between the open end 84 and the aperture 100.
  • This continuous ring of material provides elevated hoop strength to the cup receptacle 60 at a region where a user is more likely to grasp or handle the cup receptacle 60.
  • desired hoop strength of cup receptacle 60 at likely user handling regions is maintained while still affording an understanding of liquid level.
  • tactile feedback members 110a, 110b can be formed or provided at opposite sides of the aperture 100.
  • the tactile feedback members 110a, 110b allow a user to know, without looking at the cup receptacle 60, that they are gripping an area adjacent the aperture 100, such that they can properly locate their hand(s) and avoid inadvertently applying excess pressure (such as by squeezing) to the liner 64 ( FIG. 2 ) through the aperture 100. It has been found that squeezing the liner 64 when it is filled with paint can cause spilling of paint (by forcing it upward and out of the open end of the liner 64 or accidental disconnection of the lid 62 ( FIG. 2 ) from the liner 64 through excess deformation of the open end of the liner 64).
