Description

[0001] This application is a divisional application of the patent application with national application number 201780006750.1, invention name “Modular spray gun cover assembly and method of design and use”, and the date of entering the Chinese national phase is July 13, 2018. Background Art

[0002] Liquid spray guns are often used to spray coatings such as stains, primers, paints, sealants, etc. onto surfaces. It is known to provide a liquid spray gun having a paint cup for containing the liquid to be sprayed. The paint cup may include a cover for connection to the spray gun. There is a need for improved paint cups, components of paint cups including covers, and methods of design and use thereof. Summary of the invention

[0003] It has been observed that when used in its typical environment (e.g., in a mixing room of an automobile collision repair shop), the paint cup and its components have a tendency to become coated in paint. This coating of paint may cause practical difficulties for the painter. For example, even though the paint cup may be transparent (so as to allow viewing of the contents of the cup) at the time of purchase, viewing of the contents eventually becomes difficult or impossible due to the accumulation of dried paint. Specifically, in order to facilitate the correct measurement of the components of the paint or other substances, the transparent paint cup system generally includes a mixing ratio meter visible from the outside of the cup. The mixing ratio meter may be a separate liner, or it may be displayed on the paint cup itself. In order to prevent the accumulation of paint and maintain the visibility of the mixing ratio meter, the painter needs to use a solvent to clean the paint cup, or purchase a new paint cup. If the painter is then forced to purchase a new cup to replace the contaminated cup, a large amount of plastic material may need to be discarded, and the cost of the new cup may be significant.

[0004] The present disclosure relates to improved spray gun cups, spray gun cup receivers, and methods of using the same. In certain embodiments, less material may be used to manufacture the spray gun cup receiver, resulting in a spray gun cup that is cheaper to manufacture, lighter to use, and creates less trash when disposed of. The spray gun cup receiver according to the present disclosure may also allow for increased visibility of the contents of the spray gun cup through its sidewalls due to the provision of openings therein. This may be particularly advantageous during paint mixing when a painter may wish to view the levels of various liquids added to the spray gun cup to ensure the correct volumes and / or ratios of components being used. Because the openings do not become coated with paint, the contents of the spray gun cup may continue to be easily viewed even if the remainder of the sidewalls become coated with paint.

[0005] Furthermore, due to the nature and arrangement of the support member in the sidewall of the spray gun cup receptacle, the support member leaves a sufficient portion of the opening unobstructed so that the contents of the spray gun cup are visible at every height from at least one viewing direction. In other words, if a painter wishes to ensure that the level of liquid in the spray gun cup is at a certain height, where that height is blocked by the support member in one rotational position, the painter need only rotate the spray gun cup—or view the spray gun cup from another direction—until that height becomes visible. In this way, the painter can determine the precise level of the contents at any height, regardless of the opacity of the spray gun cup receptacle.

[0006] The spray gun cup receiver according to some embodiments of the present disclosure can provide strength, rigidity and structure during paint mixing. In some embodiments, the spray gun cup receiver remains in place while spraying. In such embodiments, the spray gun cup receiver can also provide strength, rigidity and structure when the spray gun cup is connected to the spray gun and during the painting process itself. These benefits can be achieved while reducing the amount of raw materials required for manufacturing (compared to a paint cup with a continuous wall).

[0007] In some embodiments, the spray gun cup may include a liner that can be inserted into a spray gun cup receiver. In such cases, the spray gun cup receiver can serve as an outer support cup.

[0008] In some embodiments, the spray gun cup may include a capping member that may optionally include an integrated filter. The integrated filter can eliminate the need for a separate filter by allowing the user to mix the paint in the paint cup itself (i.e., without having to transfer the paint from another receiver). Because the number of transfer steps is reduced, the amount of wasted paint is reduced. Examples of capping members and liners suitable for use in some embodiments of the present disclosure can be found in PCT Publication WO 1998 / 032539 to Joseph et al. (alternatively, U.S. Publication US 2004 / 0256484 A1, the disclosure of which is hereby incorporated by reference in its entirety).

[0009] The spray gun cup and spray gun cup receiver according to the present disclosure can provide the necessary structure to withstand all typical forces in the use of paint spraying system. In the event that a portion of the spray gun cup receiver blocks the view of a portion of its contents, the receiver, liner or mixing ratio meter (if provided) can be rotated or otherwise adjusted to reveal any portion of the contents previously concealed by the spray gun cup receiver. Visibility of the contents is thus ensured while maintaining sufficient strength, rigidity and structure as required throughout the mixing, connecting and painting process.

[0010] Compared to known systems, the spray gun cups, receivers, covers and liners according to the present disclosure can also facilitate assembly, use, disassembly and cleaning. In some embodiments, the cover can be directly connected to the receiver without a separate collar, and complementary connection features are provided on the cover and receiver to facilitate part alignment, while speeding up connection and reducing errors.

[0011] In addition, embodiments according to the present disclosure can help users separate the liner from the closure to which the liner is securely sealed. The features disclosed herein can provide this functionality while also reducing the possibility of rupturing the liner and / or causing paint to spill.

[0012] Additionally, some embodiments may provide improved tactile feedback to a user grasping an apertured receptacle to guide the user to avoid improperly clamping or squeezing a paint-filled pad, thereby reducing the likelihood of costly spills.

[0013] Additional embodiments disclosed herein can increase flexibility and reduce manufacturing costs of components (eg, closures) for spray gun cups. For example, closures disclosed herein can be assembled from modular components, the benefits of which are described more fully below.

[0209] It should be noted that in the drawings, some elements may exist in identical or equivalent multiples; in such cases, one or more representative elements may be designated by reference numerals only, but it should be understood that such reference numerals apply to all such identical elements.

[0210] Figure 1A and Figure 1BAn exemplary embodiment of a spray gun cup receiver 100 according to the present disclosure is shown. The spray gun cup receiver 100 includes an open end 110 that provides access to an interior cavity 120. Opposite the open end 110 is a base end 130. As shown, the base end 130 includes a substantially flat configuration with optional feet 132, thereby allowing the base to be stably placed directly on a flat work surface W ( Figure 1A The number, shape and placement of the legs 132 may vary as desired. In some embodiments, the base end 130 itself is not flat, but may be held stationary on a work surface as described above with the aid of additional structures (i.e., retainers, etc.).

[0211] Regardless of whether the base end 130 is flat, a base end plane 134 may be drawn through the base end 130 (when at rest and upright as noted above) parallel to the work surface W, as shown in FIG. Figure 1B shown.

[0212] In this embodiment, the sidewall 140 surrounds the cavity 120 and connects the open end 110 to the base end 130. The sidewall 140 includes a series of openings 150 (at least two, but in this particular embodiment, eight) penetrating the sidewall 140 to allow the contents of the cavity 120 to be viewed through the openings. There is no requirement as to how much material is needed to form the sidewall 140; it should be understood that the sidewall 140 is present as long as the open end 110 and the base end 130 are connected. As shown, the openings 150 are separated by support members 160 and support members 166. Generally speaking, the support members 166 provide support in the axial direction (along the central axis 101 and orthogonal to the base end plane 134), while the support members 160 provide particularly hoop strength to the spray gun cup receiver 100 at a location intermediate between the open end 110 and the base end 130. In the illustrated embodiment, there are four vertical support members 166. However, it is contemplated that there may be a different number of support members 166 (e.g., one, two, three, five, six, or seven or more), and that the support members may be non-vertical or only approximately vertical. "Approximately vertical" means that an imaginary straight line drawn to represent the average of the trajectory of the support members from the base end 130 to the open end 110 is within + / - five degrees of the vertical plane. It should be understood that the term "vertical" as used herein refers to the orientation of the geometry assuming the spray gun cup receiver 100 is disposed, wherein the flat base end 130 is disposed on a horizontal plane (flat work surface).

[0213] In some embodiments, the sidewall 140 of the spray gun cup receiver 100 can be highly porous so that relatively minimal support structure (e.g., support member(s) 160 and / or support member(s)) is provided. In such cases, it can be advantageous to construct the spray gun cup receiver (particularly the sidewall 140) from a relatively strong material such as filled polyamide.

[0214] exist Figure 1A and Figure 1B It can be further seen in the embodiment of the spray gun cup receiver 100 that the receiver connection structure 170 is included near the open end 110 thereof. The receiver connection structure 170 enables the separate cover member 300 ( Figures 1A to 1D 100). As shown, the receiver connection structure 170 includes threads. However, other connection structures can also be used to provide different connection mechanisms (e.g., a screw wedge connection, a snap fit connection, a push fit connection, a twist lock connection, a clamp connection, a latch connection, a hinge connection, or a combination thereof).

[0215] Now go to Figure 1C , similar to Figure 1A and Figure 1B The spray gun cup receiver 100 shown is also provided with a volumetric mark "V". The volumetric mark provides a way for the painter to determine the volume and / or ratio of the liquid component(s) in the cavity 120. The volumetric mark can be provided on a separate sleeve 600 (see, e.g. Figure 4C and Figure 5C ), embossed or otherwise disposed on the gasket 200, or otherwise positioned between the spray gun cup receiver 100 and the cavity 120 that can hold the liquid.

[0216] like Figure 1B and Figure 1C As can be seen in FIG. 1 , the support member 160 is disposed at a suitable support member 160 angle α that allows the volumetric mark to be viewed at any height within the cavity 120. For example, although Figure 1C As shown, the "10 oz." marking is hidden behind the support member 160, but simply rotating the volume mark will enable it to be viewed (e.g., by rotating the volume mark so that "12 oz." will appear in the lower right opening). Alternatively or in addition, the volume mark can be repeated so that the same volume mark appears in more than one position, where at least one of the positions is not visually imprisoned by the support member 160. In this way, the arrangement of the support member 160 can allow the volume of the contents at any liquid level to be accurately determined.

[0217] exist Figure 1A and Figure 1BIn the exemplary embodiment of FIG. 1 , the angle α of the support member 160 is about 7.5 degrees relative to the base end plane 134. Figure 1C In the embodiment of FIG. 1 , the support member 160 angle α is about 25 degrees relative to the base end plane 134 (in order to make the trajectory "T" described below more visually obvious). However, the support member 160 angle α (or "angles" in the case of more complex shapes) may be selected to be any angle greater than 0 degrees and less than 90 degrees (i.e., the support member 160 is neither parallel to the base end plane 134 nor orthogonal thereto) that both facilitates the structural requirements of the spray gun cup receiver 100 and provides visibility at all liquid levels in the cavity 120 as described herein through the at least one opening. The support member 160 should divide the at least two openings 150 so that the openings 150 are at least partially vertically positioned one above the other, and therefore a support member 160 angle α much less than 90 degrees (e.g., 30 degrees or less) is desirable for the largest spray gun cup receiver 100 sizes and geometries. As can be seen in the embodiment of the drawings, the aperture 150 is divided by support members disposed at a support member 160 angle α so that the upper aperture is positioned higher than the lower aperture, thereby allowing visibility at all fluid levels.

[0218] In some embodiments, multiple support members 160 with different corresponding angles α1, α2, α3, etc. can form more complex shapes (see, e.g. Figure 2 and Figure 3 ). In some embodiments, the support member 160 angle α is at least about 2 degrees relative to the base end plane 134. In some embodiments, the support member 160 angle α is less than or equal to about 30 degrees relative to the base end plane 134. In some embodiments, the support member 160 angle α is in the range of about 2 degrees to about 30 degrees relative to the base end plane 134, including but not limited to 4 degrees, 7 degrees, 11.5 degrees, 16 degrees, and 25 degrees, including any angles therein.

[0219] like Figure 1DAs shown in the embodiment of , when the support member 160 circumscribes the cavity 120, the trajectory "T" followed by the support member can be described as a non-circular ellipse. As used herein, a "non-circular ellipse" refers to an ellipse whose eccentricity is not zero. In an embodiment in which the sidewall 140 of the spray gun cup receiver 100 is generally cylindrical, the eccentricity can be calculated as the sine of the support member 160 angle α in degrees (i.e., eccentricity = SIN(α)). Generally speaking, for such embodiments, the eccentricity will increase as the support member 160 angle α increases, and vice versa. In some embodiments, the eccentricity of the trajectory "T" is at least 0.03. In some embodiments, the eccentricity of the trajectory "T" is less than or equal to 0.5. In some embodiments, the eccentricity of the trajectory "T" is in the range of about 0.03 to about 0.5.

[0220] It should be understood that the trajectory "T" need not be strictly elliptical in order to fall within the scope of the present disclosure. For example, the spray gun cup receiver 100 may be formed to be generally cylindrical, but with a slight draft angle (e.g., about 3 degrees) such that its profile increases from the base end 130 to the open end 110, resulting in the trajectory "T" along the support member 160 angle α being generally elliptical, but in fact slightly "egg-shaped".

[0221] In other embodiments, the support member 160 may follow a different trajectory or trajectories. For example, Figure 2 and Figure 3 An alternative embodiment of a spray gun cup 500 receiver is shown, which includes a spray gun cup receiver with Figures 1A to 1D Embodiments may include more than one support member 160 disposed in different manners. Alternatively or in combination, the support members 160 may be disposed along a trajectory whose support member 160 angle α varies as its position around the sidewall 140 changes—for example, a sine wave, a square wave, or a sawtooth pattern. Such waves or patterns may be repeating or irregular. In addition, although the embodiments of the spray gun cup 500 receiver shown herein all show a generally circular cross-section, this is not required. For example, the cross-sectional shape of the spray gun cup receiver 100 at any given height may include a polygon such as a hexagon or an octagon or any other shape that allows the functional purposes set forth herein to be achieved. For example, in all cases, the support members 160 will be shaped and arranged to enable visibility of the cavity 120 as described elsewhere herein.

[0222] Figure 4A As shown in FIG. (for example, in Figure 1A The spray gun cup 500 of the spray gun cup receiver 100 shown in FIG. 1 includes a gasket 200 positioned in the cavity 120 of the spray gun cup receiver 100. The gasket 200 has an open end 210 corresponding to the open end 110 of the spray gun cup receiver 100 (see FIG. 1 ). FIG. 4C to FIG. 4D ). The cover member 300 is fixed to the spray gun cup receiver 100, to the liner 200, or to both. The cover member 300 can be fixed in a variety of ways. FIG. 4A to FIG. 4D As shown, the optional collar 400 (compare FIG. 5A to FIG. 5D ) The cap member 300 and the gasket 200 are captured between the collar 400 and the spray gun cup receiver 100 via a collar connection structure 470 (in this case, threads). Any of the receiver connection structures 170 described earlier can be used in a similar manner to allow the optional collar 400 to be attached to the rest of the spray gun cup 500. In addition or alternatively, the cap member 300 itself can be provided with a cap connection structure 370 to complement the collar connection structure 470. In such embodiments, for example, the collar 400 can be configured to attach from below the cap member 300 to capture the gasket 200 between the cap member 300 and the collar 400. In such embodiments (and in other embodiments described herein), the spray gun cup receiver can be kept with the spray gun cup during spraying, or the cap, liner and collar can be separated or removed from the spray gun cup receiver 100 as a unit during spraying (in which case the spray gun cup receiver 100 can be used primarily as a mixing container).

[0223] As shown, the capping member 300 includes a liquid outlet 310 and one or more outlet connection members 320 to allow the capping member 300 to be connected to the liquid inlet of the spray gun. The outlet connection member 320 can be disposed on the liquid outlet 310, near the liquid outlet, adjacent to the liquid outlet, or away from the liquid outlet, as long as the outlet connection member facilitates a secure, liquid-tight connection to the spray gun. Optionally, the capping member includes a filter (not shown) to allow the liquid in the spray gun cup to be filtered before spraying.

[0224] The liquid outlet 310 and / or the outlet connection member(s) 320 may be integrally formed with the remainder of the closure 300. Alternatively, these components may be initially formed as separate modular parts or assemblies that include connection geometry to allow connection to the remainder of the closure 300. Examples of such configurations are described in Figures 17 to 18A , each depicting an exemplary closure 300 including a modular closure base 304 and a modular liquid outlet 330 connected thereto. Fig.17A and Fig.18A The disassembled state is shown respectively. Fig.17 and Fig.18 components, and Fig.19The modular closure base 304 is depicted as a kit provided with a plurality of modular liquid outlets 330 configured to fit a plurality of spray guns (in this case, the alternative spray guns are labeled "B," "C," "D," "E," etc.). Such an approach can be advantageous, for example, by allowing a single closure / receiver combination to connect to multiple spray guns without requiring (i) separate adapters; or (ii) separate molds to form a custom closure for each gun. Instead, the universal modular closure base 304 can be manufactured in a single (potentially larger) tool, while the smaller modular liquid outlets 330—which presumably will be manufactured at a lower volume—can be manufactured on smaller, less expensive molds and equipment. Using this approach, changes in the connection geometry of a particular spray gun, or the introduction of a new spray gun, can be accommodated without modifying the mold for the modular closure base.

[0225] Examples of outlet connection members 320 for use with the closure 300 described herein (e.g., in the kit described in the preceding paragraph) include, for example, those shown and described in the following patent applications: U.S. Patent Application 15 / 375,556 (3M Case No. 78953US002, entitled “Reservoir systems for hand-held spray guns and methods of use”); and U.S. Provisional Patent Applications 62 / 322,492, 62 / 279,619, and 62 / 279,537 (each: 3M Case No. 78171US002, entitled “Connector systems for hand-held spray guns”; and 3M Case No. 78171US002, entitled “Wide-Mouthed Fluid Connector for Hand-Held Spray Guns”. 77498US002 entitled "3M Guns" and 3M Case No. 77499US002 entitled "Button-Lock Fluid Connector for Hand-Held Spray Guns"), the contents of which are incorporated herein by reference in their entirety.

[0226] The modular liquid outlet 330 provided above may alternatively be attached or preassembled to the end of a paint supply line or pouch, etc., and then connected to the spray gun paint inlet. In this way, paint can be directly to the spray gun without the need for a modular cover base 304, a gasket 200, or a spray gun cup receiver 100.

[0227] Constructing the closure 300 using a modular liquid outlet 330 and a modular closure base 304 may provide additional advantages or allow for more complex geometries to be feasible than would be possible using other methods such as injection molding. For example, in a given closure 300, it may not be possible to form a particular geometry in an injection molded part due to the location of the mold parting and the necessary trajectory of the slide required to form certain features. However, if the closure 300 is divided into modular components, the mold may be designed to directly contact the surface of each modular component that is not accessible on a one-piece closure. Therefore, additional geometric complexity may be achieved.

[0228] Modular closure components may also be constructed of different materials than desired for the application. For example, it may be desirable to use an engineering plastic for the modular liquid outlet 330 (due to the strength and durability required for secure and permanent connection to the spray gun), while a low-cost polymer may be used for the modular closure base 304.

[0229] The modular liquid outlet 330 can be secured to the modular closure base 304 (or vice versa) in a variety of ways. For example, spin welding, sonic welding, quarter turn locks, other mechanical locking mechanisms, gluing / adhesives, threads, other mechanical fasteners (i.e., screws, rivets, and / or molded posts) cold / hot formed and mushroomed down to hold / maintain one or more components in place and provide a suitable leak-proof seal.

[0230] exist Figures 17 to 17A In the illustrated embodiment, the modular liquid outlet 330 is positioned against and fixed to the modular closure base 304 with the help of a sealing feature 306 and an alignment feature 309. In this case, the sealing feature 306 is located on the modular closure base 304 and includes a cylindrical protrusion 307, which includes one or more radial sealing ribs 308 adapted to interact with the inner surface 311 of the liquid outlet 310 to form a liquid-tight seal when the modular liquid outlet 330 is assembled to the modular closure base 304. Similarly, the alignment feature 309 helps to position the two parts together and also helps to resist relative rotation of the parts during assembly. If desired, the two parts can be additionally fixed by adhesives, welding, etc. after assembly. Alternatively, the fit between the modular liquid outlet 330 and the modular closure base 304 can be constructed to be sufficiently strong without the help of additional fasteners (e.g., by friction fit, snap fit, threads, etc.). The sealing features 306 and / or the alignment features 309 may be interchanged between the two parts as appropriate when in use.

[0231] exist Figures 18 to 18AIn the illustrated embodiment, the modular liquid outlet 330 is secured to the modular closure base 304 by welding and / or adhesives, etc. In this case, the adhesive joint and / or welded joint acts to maintain and form a liquid-tight seal when the modular liquid outlet 330 is assembled to the modular closure base 304.

[0232] It should be understood that the description herein and throughout FIGS. Fig. 16B Any of the covers 300 shown in FIG. 300 may be constructed and / or provided in a modular manner as described in the preceding paragraphs and in Figures 17 to 19 in the kit shown.

[0233] Figure 4B It shows that Figure 4A Also included are implementations of the volume marker V as described elsewhere herein.

[0234] Figure 4C An exploded view of a spray gun cup 500 is shown including volumetric markings disposed on a sleeve 600. As shown, it can be seen that the sleeve 600 can include a sheet of material that can be deformed into the cavity of the spray gun cup receiver when inserted. Alternatively, the sleeve 600 can be provided as a pre-molded unit that can be dropped into the spray gun cup receiver 100 without being deformed.

[0235] The corresponding receiving geometry of the bushing 600 or the spray gun cup receiver 100 can be configured so that the bushing 600 is aligned in the cavity and relative to the opening and is thus substantially fixed to prevent rotation. In such embodiments, the bushing 600 can be provided with repeating volumetric markings "V" as described above so that each liquid level can be seen from at least one position around the spray gun cup receiver. In some embodiments, the bushing 600 can be aligned in more than one position so that the bushing can be inserted and fixed in more than one position.

[0236] Figure 4D An exploded view of a spray gun cup 500 is shown that does not include a constant volume mark V, but nevertheless wherein the contents of the cavity are visible at all fluid levels through at least one opening as described elsewhere herein. In order to make the contents of the liner 200 (when set) visible, the liner is generally constructed of a transparent or translucent material.

[0237] Figure 5A Shown with Figure 4AThe spray gun cup 500 is different from the spray gun cup shown in , because the collar 400 is not used. In contrast, the cap member 300 is adapted to be secured without the need for a collar. Although originally constructed as described above, the cap member 300 may be provided with a cap connection structure 370, which may alternatively be provided on the collar 400. For example, the cap member 300 itself may be screwed directly into the spray gun cup receiver 100 (via the cap connection structure 370), or screwed onto the spray gun cup receiver, or both. Alternatively (or in combination), the cap member 300 may include a cap connection structure 370 to be compatible with the previous description relative to the spray gun cup receiver 100. Figure 1A The receiver connection structures 170 discussed (eg, a snap-fit ​​connection, a push-fit connection, a twist-lock connection, a clamp connection, a latch connection, a hinged connection, or a combination thereof) are complementary.

[0238] Figure 5B Shown as Figure 5A Also included are implementations of the volume marker V as described elsewhere herein.

[0239] Figure 5C An exploded view of a spray gun cup 500 is shown including volumetric indicia disposed on a sleeve 600. As shown, it can be seen that the sleeve 600 can include a sheet of material that can be deformed into the cavity of the spray gun cup receiver 100 when inserted. Alternatively, the sleeve 600 can be provided as a pre-molded unit that can be dropped into the spray gun cup receiver 100 without being deformed.

[0240] Figure 5D An exploded view of a spray gun cup 500 is shown that does not include volume markings, but nonetheless wherein the contents of the cavity are visible at all fluid levels through at least one opening as described elsewhere herein. Figure 5C and Figure 5D As shown in both, the cover connection structure 370 includes a snap-fit ​​connection with the complementary receiver connection structure 170. In order to make the contents of the liner 200 (when provided) visible, the liner is typically constructed of a transparent or translucent material.

[0241] Figures 6 to 8 An additional embodiment of a spray gun cup 500 is shown, which is similar to FIG. 5A to FIG. 5D The embodiment has a cover 300 that is directly connected to the receiver connection structure 170 without the need for a separate collar 400. Figures 9 to 9A An exemplary liner for use with such a spray gun cup 500 is shown in Figures 10 to 10A An exemplary spray gun cup receiver is shown in Figures 11 to 16B Various exemplary embodiments of cover 300 are shown in FIG.

[0242] exist Figure 6In the illustrated embodiment, the spray gun cup receiver 100 includes one or more apertures 150. While such apertures 150 may be arranged in the manner described above (i.e., intersecting one or more support members), the support members are not shown here. One or more tactile feedback members 152 are arranged adjacent to the aperture(s) and protrude from the outer wall 104 of the spray gun cup receiver 100. Alternatively, the tactile feedback members 152 may be arranged as depressions in the outer wall 104, or as textures on the outer wall 104, for example. The tactile feedback member(s) allow the user to know that they are gripping an area adjacent to the aperture without viewing the spray gun cup 500, so that they can properly position their hand(s) and avoid inadvertently applying excessive pressure (such as by squeezing) to the pad 200 through the aperture(s). It has been found that squeezing the liner 200 when filled with paint can cause the paint to spill (by forcing the paint upward from the open end 210 of the liner 200 ), or the closure 300 to accidentally disconnect from the liner 200 through excessive deformation of the open end 210 of the liner 200 .

[0243] Although Figures 6 to 16B The exemplary spray gun cup receiver shown in FIG. 1 includes the Figure 5D Compared to the different configurations of openings, it should be understood, however, that any of the closure 300 and spray gun cup receiver 100 described herein may be used with one another, provided any necessary modifications are made to the respective receiver, closure, and / or optional collar connection structure (170, 370, 470, respectively).

[0244] Figures 11 to 16B Various exemplary embodiments of closures that may be used for the spray gun cup 500 receiver described herein are shown. Fig.11A and Fig. 11C As can be seen in , the closure 300 may include one or more gasket sealing members 340. When provided, the gasket sealing member 340 operates as follows: the gasket 200 is inserted into the open end 110 of the spray gun cup receiver 100; paint is added through the open end 110 of the gasket 200; the closure 300 is positioned in the open end 110 of the gasket 200 (and the receiver); the closure 300 is secured to the receiver in a direction along the central axis 101 so that the open end 110 of the gasket 200 is radially stretched over the gasket sealing member 340 and ultimately into fully sealed engagement. The gasket sealing member 340 may include one or more radially outwardly projecting features, such as Figures 11 to 11E and Figures 15 to 19 The gasket sealing member may additionally (or alternatively) include a chamfered or otherwise tapered surface, such as Figures 12 to 14A Those shown in .

[0245] The closure 300 may also include a gasket seal fastener 342, an example of which is best described in Figures 12 to 13A The liner seal fastener 342 can enhance the retention of the liner on the closure 340, and some embodiments can help provide a tactile and / or audible assurance to the end user that the closure 300 is securely seated in the liner 200 by allowing a "snap" action discussed in more detail elsewhere in this specification. The liner seal fastener 342 is particularly suitable for use with a chamfered or otherwise tapered liner sealing member 340 as described above, because such a tapered surface can lack other features that can help resist the liner 200 from being pulled off the closure (e.g., the liner 200 is shown having a Figures 11 to 11E and Figures 15 to 19 ). However, even in these configurations, a liner seal fastener 342 may be employed as an additional support.

[0246] Although the entire spray gun cup 500 (or just the closure 300 and liner 200) may be discarded after use, a user may wish to remove the liner 200 from the closure 300 to add additional paint or replace the closure 300 with a fresh one (e.g., when the filter 301 in the closure 300 has become clogged or when paint has dried thereon). However, it has been found that because the liner is stretched to fully seal against the liner sealing member 340, the liner 200 may be difficult to remove from the closure 300 without damaging the liner 200 or spilling paint. Therefore, the liner 200 may be provided with one or more release tabs 204 that facilitate easy removal of the liner 200 from the closure 300 after assembly. These release tabs 204 are Figure 7 , Fig. 9 and Fig.9A is shown in more detail in . Figure 8 An embodiment is shown in which the liner 200 optionally does not include a release tab 204.

[0247] The closure 300 may include a closure body 360 and may be provided with a flange 371 around its periphery. In the illustrated embodiment, the flange 371 carries at least a portion of the closure connection structure 370, and specifically (one or more) closure engagement members 372. In some embodiments, one or more flange openings 380 are provided so that the flange 371 is interrupted around its periphery. The (one or more) flange openings 380 may allow clearance for (one or more) release tabs 204 on the liner 200 to extend from the spray gun cup 500 for convenient grasping and lifting of the liner 200. As shown, the (one or more) flange openings 380 penetrate the closure connection structure 370. Therefore, adjacent to the (one or more) annular interruptions 304 is the flange tab 372, on which the closure engagement member 374 is provided to interact with a complementary feature on the receiver connection structure 170. In some embodiments (see, e.g. Figures 12 to 13A ), the presence of the flange opening 380 allows access to a mold (e.g., an injection mold) to form the gasket seal fastener 342).

[0248] In the illustrated embodiment, the receiver engagement member(s) 172 and the closure engagement member(s) 372 include easy-to-start partial threads, whereby the closure 300 is easily aligned and attached to the receiver 100 with a partial turn. Fig.10 and Fig. 10A 300 . As shown, the receiver engagement member 174 includes a cam surface 176 facing away from the open end 110 of the spray gun cup receiver 100. As shown, the cam surface 176 can be linearly inclined, or can be flat (not inclined), curved, or can include any combination of inclined portions, flat portions, and / or curved portions. If completely flat, the inclined or curved surface portion can be disposed on a complementary cover cam surface 376 (described in more detail elsewhere) so that the cam action is promoted when the parts interact. Regardless of the specific configuration of the cam surface 176, the cam surface 176 is adapted to interact with a complementary structure on the cover 300 to allow the cover 300 to be securely attached to the spray gun cup receiver 100 so that the gasket 200 is maintained in a sealing relationship between the cover 300 and the receiver.

[0249] It should be understood that while features 176 and 376 are referred to as "cam surfaces," it is not strictly necessary that a camming action (which should be understood herein to include the application of a force along the central axis) occur during interaction. Rather, in some embodiments (see, e.g., the specific twist-lock embodiments described below), the corresponding cover and receiver engagement members (374, 174) that may carry cam surfaces (376, 176) do not require the application of an axial force during installation and / or removal.

[0250] As shown, the receiver engagement member 174 is additionally provided with a stop feature 178 that prevents over-rotation of the closure 300 during installation and provides an indication to the user that the closure 300 has been fully installed on the spray gun cup receiver (see, e.g. Figures 10 to 10A ). When optionally provided, the stop feature 178 may be formed as a continuation of the cam surface 176 (as shown), or may be spaced apart from the cam surface 176. It has been found that the presence of the stop feature 178 may be particularly beneficial on disposable (e.g., plastic) parts, where over-rotation may cause deformation of the engagement feature and ultimately potential failure of the connection.

[0251] In one embodiment, the closure engagement member 374 is adapted to align and mate with the receiver engagement member 174 so that the closure 300 (i) can be "snapped" into the liner 200; (ii) will not be cross-threaded; and (iii) will resist rotation in the wrong direction when the closure is initially assembled to the spray gun cup receiver. To achieve these benefits, a series of design features are employed (although all of the features are used together in the illustrated embodiment, they are not intended to be disclosed as being inseparable, as each feature can provide a benefit without the need for the other(s) features).

[0252] One feature includes spaces between adjacent receiver engagement members 174 that allow the closure engagement members 374 to fully pass until the closure is substantially fully seated against the spray gun cup receiver (and / or liner 200) - although not yet fully sealed and tightened - prior to engagement of the cam surfaces on either part. In this way, the closure can be "snapped" onto the liner in one brief motion, rather than, for example, gradually advancing the two parts together as the threads tighten. The "snap" feel and / or sound results from a combination of: (i) the liner sealing member(s) 340 being rapidly advanced into the open end 210 of the liner 200, causing a portion of the liner 200 to rapidly extend over the liner sealing member 340 and then relax; and (ii) the closure edge 312 thereby impacting the liner edge 212 / receiver edge 112 as the closure 300 rapidly drops into contact. This brief snap feeling can provide tactile and / or audible assurance to the end user that the closure 300 and liner 200 are securely attached, but that the closure has not yet been secured to the spray gun cup receiver 100 .

[0253] In embodiments where the closure can be substantially fully seated in the liner 200 via a "snap" action as described above, there may be no need to provide additional camming action (e.g., via cam surface 176 and closure cam surface 376). Instead, adequate retention of the components can be achieved via a non-cam twist-lock connection. In such embodiments, the end user will (i) align the respective closure and receiver engagement members (374, 174); (ii) snap the closure into the liner; and (iii) twist the closure in a non-camming manner to engage the closure engagement member 374 against the receiver engagement member 174, such that the respective engagement members prevent the closure from being pulled out of the spray gun cup receiver along the central axis, but without providing any compression of the closure 300 against the spray gun cup receiver 100 or the liner edge 212.

[0254] Next, as described in the preceding paragraphs, when the closure 300 is placed on top of the spray gun cup receiver 100 and mounted to the gasket 200, and before being rotated to engage the easy-to-start partial threads, the rear portion 379 of the closure engagement member 374 is located at a vertical position along the central axis 101 that interferes with the front portion 179 of the adjacent receiver engagement member 174, so that the closure cannot be rotated in the reverse direction. Instead, the end user only needs to rotate the closure in the correct direction to ultimately lock the closure and gasket against the spray gun cup receiver 100.

[0255] Thus, the closure (i) is easily rotationally aligned; (ii) easily snaps into the correct axial position against the spray gun cup receiver; (iii) snaps into place to provide reassurance of a secure connection; (iv) is prevented from rotating in the wrong direction; and (v) is easily rotated in the correct direction, without risk of cross-threading, to engage the corresponding cam surfaces for complete sealing and tightening.

[0256] As shown, providing the receiver engagement member(s) 172 as partially threaded for ease of activation not only enables faster installation of the closure, but it prevents possible cross-threading, reduces the number of areas where excess paint can collect and contaminate the assembly, and facilitates cleanup.

[0257] like Fig.11 As shown, for example, the cover includes four flange tabs 372—one for each receiver engagement member 174. The flange tabs 372 may be provided as separate components that protrude from the radially outer periphery of the cover 300 along the central axis 101, such as, for example Figures 11 to 12A and Figures 15 to 16B Alternatively, Figures 13 to 14AAs shown, the flange tabs 372 may be connected by a flange bridging member 382. In either case, flange openings 380 may be provided in the region(s) between the flange tabs 372. The flange openings 380 may allow clearance for, for example, a liner release tab 204 as described elsewhere, and may additionally provide access to the end user's fingers to aid in gripping the closure 300 for installation and removal. Such additional gripping functionality may be particularly desirable in situations where the end user may be wearing gloves, and where the end user's hands (gloved or otherwise) may be slippery due to wet paint.

[0258] In embodiments including the flange opening 380, an additional benefit can be achieved in that the flange tab 372 can be more easily lifted or pried open by the end user if it is desired to release the closure 300 from the spray gun cup receiver. Such prying would require significantly more force were the flange 371 not interrupted by the flange opening 380. Such lifting or prying can be advantageous in embodiments where the closure 300 is snap-fit ​​or friction-fit onto the spray gun cup receiver 100, but can also be used to remove a closure 300 that has been screwed into place (e.g., if spilled or excess paint has dried in the assembly, making removal by rotation difficult). It should be noted that such lifting or prying functions can be best achieved without the bridging member 382, ​​although even with the bridging member 382, ​​such lifting or prying functions can be facilitated as long as each flange tab 372 is able to lift the flange tab 372 sufficiently independently of each other.

[0259] In some embodiments (see e.g. Figures 12 to 14A ), one or more access windows 373 are provided in the flange 371 corresponding to the (one or more) closure engagement members 374. The (one or more) access windows 373 can provide access by sliding in the injection mold to form a feature that would otherwise be below the flange tab 372 - such as (one or more) closure cam surfaces 376 on the (one or more) closure engagement members 374. For example, as Fig.14A As shown, the cover cam surface 376 is visible through the access window 373 viewed from the top of the cover 300.

[0260] In some embodiments (see e.g. Figures 11 to 14A ), the flange 371 is formed integrally with the cover 300 (ie, the cover body 360 and the flange 371 are integral). In other embodiments (see, for example, Figures 15 to 16B ), the flange 371 is initially formed independently of the cover body 360 and is subsequently attached to form a competing cover 300. In such cases, the flange 371 can be configured to rotate relative to the cover body 360 after being attached to the cover body 360 (e.g., Figures 16 to 16B), or may be rotationally fixed relative to the cover body 360 (as shown in Figures 15 to 15B ). When configured to rotate relative to the closure body 360, the interaction of the flange 371 and the closure body 360 can allow the closure body 360 to remain in a fixed sealing relationship against the gasket 200 and / or the spray gun cup receiver 100 while the flange 371 is rotated to cause the closure connection structure 370 to engage the receiver connection structure 170. Such relative movement can help (i) provide a seal between the closure and the gasket and / or the spray gun cup receiver, and (ii) reduce the rotational force required to install the closure.

[0261] When provided as a separate component, the flange 371 can be retained on the cover 300 via one or more flange retention features 378. An exemplary embodiment including the flange retention features 378 is shown in FIG. Figures 15 to 16B In Figures 15 to 15B In the illustrated embodiment, flange 371 is rotationally fixed relative to cover 300. Figures 16 to 16B In the illustrated embodiment, the flange 371 is allowed to rotate relative to the closure 300. In some embodiments, a full three hundred and sixty degree rotation about the central axis 101 is allowed, while in other embodiments, the rotation may be limited to a partial turn, such as, for example, ninety degrees. In the case of limited rotation, the flange rotation limiting feature 377 may be provided on one or both of the closure body 360 and / or the flange 371 (see, for example, Fig. 16C and Fig.16D ). In this example, flange rotation limiting features 377 are provided on flange 371 so that they will rotate through a predetermined arc until contacting flange retaining features 378 on cover body 360.

[0262] Even if the flange 371 is rotatable relative to the closure body 360 (e.g., by providing a sealing gasket, etc.), the separate flange 371 can be assembled in a sealing relationship relative to the closure body 360. However, this is generally not necessary because the closure body 360 carries the gasket sealing member (e.g., on a skirt that protrudes from below the closure body as shown in the drawings) and also includes an inner closure body surface 361 that concentrates paint to the liquid outlet. In other words, the closure body 361 forms a liquid conduit for paint to flow from the gasket into the spray gun, so that the separate flange 371 can be movably connected to the closure body without having to worry about forming a leak path for the paint.

[0263] In some embodiments, the liner 200 includes a liner edge 212 around the liner open end 210, which can provide additional sealing functionality when clamped between the closure 300 and the spray gun cup receiver 100. In such embodiments, the closure 300 can be provided with a closure edge 312 and a spray gun cup receiver 100 having a receiver edge 112 around the open end 110.

[0264] In such embodiments, it may be desirable for the cam surface 176—by interacting with the closure cam surface 376 on the closure engagement member 374—to enable a clamping force to be applied along the central axis 101 when the closure 300 is attached to the spray gun cup receiver 100. In such cases, one or both of the cam surface 176 and / or the closure cam surface 376 are provided with a geometry to cause relative clamping movement of the closure 300 and the receiver along the central axis 101 during connection. In one embodiment, such a geometry may be provided at least in part by an inclined or curved cam surface portion as described above, either on the cam surface 176 or the closure cam surface 376, or on both the cam surface 176 and the closure cam surface 376.
