Description

200539951

[Technical Field to which the Invention belongs] The present invention relates generally to a fluid supply cup for a fluid applicator, and more particularly to a fluid supply cup with antistatic properties. [Prior art]

Some fluid applicators, such as gravity-supply jets, have a fluid supply cup erected on top of the fluid applicator. The fluid supply cup may have a disposable liner. Fluids such as paint or other coatings can be measured and mixed in a separate container and later injected into the disposable liner for use, or can be measured and mixed in the disposable liner itself. Disposable liners reduce cleaning time and costs. However, when disposable liners are used in certain coatings with a chargeable material, such as paint containing metal particles, the uniformity of the coating may change during the application process. As a result, the obtained part has an uneven coating. In view of the possible problems caused by uneven coatings, some users have begun to recommend the use of discarded liners when using certain coatings. SUMMARY OF THE INVENTION Therefore, there is a need for a fluid supply cup that does not affect the uniformity of the coating during dispensing.

200539951 The present invention meets this need by using a flexible disposable cup in a fluid supply assembly. The disposable cup system is made from. During the dispensing, the coating mixture particles will not stick to the disposable cup to keep the coating mixture. "Antistatic material" means a material with repellency. The term "antistatic material" means conventional materials, as well as static dissipative materials, that is, materials with a higher discharge rate than ordinary antistatic additives, and conductive materials with a load capacity. [Embodiment] Fig. 1 shows a device attached to a fluid application device. In one embodiment, the fluid supply assembly is used for paint or other coating) to the flow applicator (such as a coating invention will describe a paint sprayer (such as a gravimeter) for applying paint to the coating The surface of the layer substrate. The paint sprayer (such as a car repair shop) can be used for repainting a car in a gas store. A paint sprayer describes the fluid supply assembly, which is used in the present invention. It can be used to supply other charged particles. FIG. 1 shows a paint sprayer i 0. 15. A handle 30 supported by a nozzle device body 丨 5 rear end 35 fastened to the front end 25 of the body 15. The body 15 can be pivoted tightly to manually activate the spray Nebulizer 10. It is close to the feed; the flexibility is lost to the uniformity of the chargeable particles in an antistatic material. The antistatic material is known to have an electrostatic charge capacity that is faster than a fluid supply group that discharges static electricity quickly. (Such as a material sprayer). This supply is used in the paint spray-repair market ... Although it is related to fluids that are not limited to this. It includes a beaker 20, and a bezel 40 to r nozzle to the nozzle. Device 4 200539951 2〇 A top-mounted paint supply assembly 45 to the main body i5 is erected at the front end 25. Two pi knots 50 to one air Zhao hose (not shown) are used to deliver pressurized gas to the nozzle device 20, which is by lever 40 controls the transmission of pressurized gas Zhao. The compressed gas vessel is transmitted from the gas connection 50 to the mouth nozzle through the inner channel (not shown), and the compressed gas Zhao is used to make the coating mist and It is conveyed to the spray paint by the nozzle device 20 around the paint shaft 55. The paint is conveyed to the nozzle device 20 by the paint supply module 45. Embodiment 1-3 of the paint supply module 45. The paint supply module includes a discard type Cup 55. Disposable cup 55 has a generally cylindrical side wall 60. The exit end 65 of the top of the cup is open and the bottom 70 is closed. The side 60, exit 65 and bottom 7 Define an internal 75 ° During use, the disposable fluid supply cup may generate electrostatic charges. Therefore, the coating on the right contains charged particles that will be attracted to the cup surface. When the charged particles stick to the cup The composition of the coating changes. This results in The uniformity of the coating applied during the process changes, which may cause difficulty in uniform application. For example, the coating may be a full compound of a coating containing metal particles. When the coating is applied, the metal particles may stick to The fluid is supplied to the cup surface of the cup. When this phenomenon occurs, the color of the applied paint changes, and the article painted by the tile has an uneven color. 200539951 The disposable cup of the present invention is made of antistatic material. The electrostatic charge that may be generated during manufacturing, storage, and use is eliminated. The electrostatic charge is eliminated, and the coating mixture in the coating process can be eliminated during spraying: it will stick to the disposable cup. Therefore, 'in the application process Keep the ::: tertiary: the average sentence of things. Chargeable particles include, but are not limited to: particles. & Non-gold, the antistatic material contains an antistatic polymer material. Suitable polymeric materials include, but are not limited to, polyethylene or other soft, flexible polymers. If desired, 胄 polymeric materials :: Polymer materials that are generally transparent 'or translucent or even opaque. "Antistatic additives"-the word means-general antistatic additives, four additives and conductive additives. Antistatic agents can be applied to the surface after casting (inside: before incorporating the polymer or after forming (outside).

It has some inherent conductivity functions and other functions that are absorbed by the atmosphere at the same time. Conventional antistatic materials have a resistivity of 1012 ohms. The anti-static cover is completely or completely filled. Compared to a ratio, which is usually determined by atmospheric conditions, it is generally between about 109 per square and the electrical material can be a surface resistive, surface-like antistatic material, eliminating charges such as relative temperature and humidity. The static dissipative material has a greater capacity to discharge static charges than ordinary antistatic materials. 6 200539951 '1. The electrical dissipative material has a resistivity between approximately 10 and 109 ohms per square. The static dissipative material can be covered or completely filled. # 电 dispersion materials can be affected by atmospheric conditions. Conductive materials have the ability to quickly discharge static charges. The conductive material has a resistivity between approximately 103 and 106 ohms per square. These materials are substantially completely filled. An electrostatic charge flows through the saturated material. Atmospheric conditions do not affect conductive materials. Suitable antistatic additives include, but are not limited to, long-chain fatty amines and amino compounds, esters, quaternary ammonium compounds, polyethylene glycol 'ethylene diether vinegar, ethoxy long-chain fatty amines, Polymeric antistatic additives composed of hydrophilic heterogeneous molecular polymers, essentially conductive polymers such as polyaniline and polythiophene, and conductive fillers such as carbon black, metal powders and fibers and graphite fibers. In use, a disposable cup made of antistatic material is filled with a coating mixture containing charged particles. The disposable cup is placed in the reusable cup holder 'and the cover is attached to the reusable cup holder. The disposable cup is thus sealed in the reusable cup holder and the outer lid. The coating mixture is applied later. The chargeable particles in the coating mixture do not stick to the disposable cup in order to maintain the uniformity of the coating mixture when applied. The disposable cup may have a flexible sidewall to allow the disposable # to be folded when applying paint. The side wall can be as thin as about 0.003 inches to 0.008 inches. In one configuration, the disposable cup may have a flexible side wall which serves to allow almost all coatings to be used to fold the disposable cup to a minimum amount of folds. The side wall adjacent to the exit end and the bottom is thicker than the middle portion of the side wall. With this configuration, when folded, the 0 cup is almost wound from the inside out. The side wall adjacent to the exit end and the bottom can be approximately two to three times thicker than the central cavity wall. For example, the side wall adjacent to the exit end and the bottom may be approximately 0.006 inches to approximately 0 015 inches, and the central portion may be approximately 0.003 inches to approximately 0.0005 inches. If desired, a thicker portion adjacent to the exit end and the bottom may cover approximately a quarter of the side wall. However, those familiar with the art will understand the use of other thicknesses and other ratios of the thicker parts. If desired, the bottom may be slightly thicker than the range of about 0.003 to about 002 inches, so that the bottom can be kept substantially flat when the side wall is folded. Since the side wall is folded, no gas is required to be discharged in the disposable cup. This allows the user to discharge the paint sprayer at any angle without leaking and can use the conventional gravity-feed paint cup to use more paint in the cup. In one embodiment, the exit end 65 of the disposable cup 55 defines a shaft 80. A flange 85 extends outward and downward from the outer edge of the exit end 65. The flange 85 ranges from about 10 to the shaft 80 of the exit end 65. To about 70. The angle α extends downward ° 8 200539951 The reusable cup holder 90 is generally cylindrical. It has a side wall 95, an open upper end 100 and a lower end 105. The lower end 105 has an opening 110. If desired, the opening 110 can cover all or almost all of the lower end 105. Alternatively, 'the lower end may have more than one smaller opening. The opening 110 of the lower end 105 allows ingress and egress of surrounding air pressure during use, which helps to fold the disposable cup. Alternatively, the reusable cup holder 90 may include more than one post 112 extending downwardly from the lower end 105. The pillar may surround the entire opening 110 (i.e., an annular rib) or only a portion of the opening. The struts 112 can help stack the fluid supply assembly as described below. The upper end 100 defines a shaft 115. A flange 120 extends outward and downward from the outer edge of the upper end 100. The flange 120 extends downward from the shaft 115 of the upper end 100 at an angle yS ranging from about 10 to about a range. This angle frame is substantially at an angle α corresponding to the flange 85 of the disposable cup 55. When the disposable cup 55 is placed in the reusable cup holder 90, the flange 120 of the cup holder 90 can be reused to support the flange 85 of the disposable cup 55.

A connecting surface 1 2 5 is provided at the upper end 100 of the reusable cup holder 90. If desired, the connecting surface 1 2 5 may extend outwardly from the side wall or from the end of the flange 120 on the side wall. The reusable cup holder 90 may be made of a rigid plastic, which includes, but is not limited to, polypropylene or high-density polyethylene. If necessary, the plastic used is strong enough so that the reusable cup holder can withstand the clamping force of a paint mixer. If required, the plastic is transparent or translucent, although it may be opaque. If opaque plastic is used, the sidewalls are too thin and should have elongated openings so that the disposable cup and its contents can be seen. — For Uncle Gong, the side wall can be between about 0.02 inches to about 0.08 inches thick.

The disposable cover 130 has a generally frusto-conical member 135. The outer edge 14 of the generally frustoconical member 135 defines a shaft 145. The angle 7 of the outer edge 140 of the generally frusto-conical member 135 is from the axis 145 to about 10. To about 70. Range. This angle T is substantially an angle α corresponding to the flange 85 of the disposable cup 55. The disposable lid 130 is mounted on the disposable cup 55, and the outer edge 140 of the disposable lid 130 matches the flange 85 of the disposable cup 55. The inside of the disposable cover 130 may have a rib 150 extending downward, if necessary. The downwardly extending rib 150 extends into the interior 75 of the disposable cup and matches the interior of the side wall 60 of the disposable cup 55 to form a seal. In addition, a sealing protrusion 155 may be provided on the inside of the disposable cover 130 to protrude downward. The downwardly projecting sealing bump 155 matches the flange 85 of the disposable cup 55 to form a seal. A joint fitting 160 is integrally connected to the generally frustoconical member 1 3 5. The joint fitting 1 60 has an opening 165 extending through itself. The disposable cover 130 may be made of a transparent, translucent or opaque plastic 10 200539951 glue. A suitable plastic contains ethylene. However, it is not limited to polypropylene or high-density polycone 180 outer flanges. Flange should be covered, and the other 90-shaped compound has a flat section with a head. If the cover is available, but

The reusable outer cover 170 has a generally frusto-conical portion 175. The generally frusto-conical portion 175 continues to define a shaft 185. The angle of 180 of this generally frusto-conical portion i 75 < 5 is a distance of ㈣185 to about 10. To about 70%. This angle 5 is roughly equivalent to the angle of U0 of the reusable cup holder Chuan. The outer edge 18 of the reusable cover n0 matches the flange 120 of the reusable cup holder 90. A complementary connection surface 19o is formed on the reusable 170o outer edge 180. In this embodiment, the complementary connection surface 190 extends downward from the outer edge 180, although different configurations are allowed. The complementary connection surface 190 matches the connection surface 125 of the reusable cup, and seals the reusable cup holder 90 and the reusable outer cover 170 together. 0 The reusable outer cover has a joint fitting 195 integrally connected to the generally conical portion 175. The joint fitting 195 extends through the opening 200 itself. The connector 160 of the disposable cover 130 is mounted on the connector accessory 195 of the reusable outer cover 170. • The reusable outer cover 170 can be made of a strong and tough plastic. If necessary, the selected plastic is strong enough. The reusable outer can bear the clamping force of a paint shaker. Examples of suitable plastics include 11

200539951 Not limited to acetal. Acetal is generally not transparent. Therefore, the use of the cover 170 may include more than one sight hole in order to use the paint level, if required. The sight hole may also allow the name of the type of coating to be written on the disposable lid, and it allows the disposable lid to be easily removed using the outer lid. A conduit 210 connects the fluid supply assembly to the paint. The conduit 210 is mated with the joint fitting 160 of the disposable cover 130 and the joint fitting 160 of the disposable cover 130. The catheter passes through its own opening 215. There is a path for the fluid to flow from the discard | inner 7 5 through the opening in the discarded cover 1 30 1 6 5 through the opening in the 215 to the paint sprayer 10. An optional filter 220 can be placed in the conduit opening 215, the opening 200 in the reusable outer cover 170, and the opening 165 in the cover 130. \ To use the fluid supply assembly, the disposable cup 55 reuse the cup Frame 90. The flange 85 of the disposable cup 55 matches the flange 120 of the cup holder 90. The flange 85 is positioned at the center of the reusable cup holder 90. Alternatively, the disposable cup 55, or the reusable cup, or the indicator 230 is provided at the same time. The indicator 230 may be molded and printed on the side, a label attached to the side, or the indicator may be provided in the form. This indicator can be used to measure the paint structure, and the repeatable user can see that the user is throwing the repeatable sprayer 10 in place. The piece 195 and the 210 have a t-cup 55 through the opening of the duct 210 2 10 or the discard type to remove impurities. Place the reusable reusable cup 55 on the rack 90, on the side, some other shape. Alternatively, 12 200539951 can use the disposable cup and reusable cup holder on a day scale, or measure the coating member with a measuring sticker. This indicator may include more than one mixing ratio mixing scale, for example: 4: 1 mixing ratio, 2: 1 mixing ratio; 3: 2: 1 mixing ratio, and so on. Each agitation ratio can contain more than one segment of different size so that different agitation ratios can be used to measure different amounts of fluid. The indicator may also include more than one general scale, that is, a scale with equally sized fragments. One universal scale may have 20 equally divided segments, another 10 equally divided segments, and 5 one third equally divided segments. There are many common dimensions if needed. The multiple universal scales allow the user to measure different fluid quantities without using agitation ratio scales that are not necessarily included. The user can select the appropriate universal scale based on the amount of fluid required. Alternatively, the measurement guide can print the indicators on a clear, thin, flat plastic month. The plastic sheet has connecting parts on the opposite sides of the plastic sheet, including, but not limited to, a sign and an elongated hole. The plastic sheet is molded into a cylinder, and the sign is inserted into the slot. The measurement guide may be placed on a table, and the disposable cup, or a reusable cup holder having the disposable cup therein may be placed inside the cylinder. ^ After measuring the coating member, The cylinder removes the discarded cup (and the reusable cup holder, if present). This effect can be achieved by lifting the disposable cup by the flange, or cutting the label and the slit hole on the plastic sheet. An optional removal tag located on the flange at a relative position of 180 degrees can assist in removing the disposable cup. 13 200539951

The discardable cup can be placed in the reusable cup holder later (> (if not already in this position). This measurement guide improves the visibility and accuracy of the coating component measurement. The rectangular shape is easy to manufacture It eliminates the need to accurately place a label on the discardable cup or reusable cup holder. It also allows a more direct view of the indicator than the label (ie, via the label, the reusable cup holder, and Because the indicator can be placed next to the disposable cup, the disposable cup is particularly advantageous for using a smaller diameter disposable cup. Finally, if the disposable cup is used alone, it is not used when pouring and measuring paint. The reusable cup holder can keep it clean. Plastic sheets can be molded into different sizes, so the measurement guidelines can be used for discarded cups of different sizes. A larger plastic sheet can be used for the reusable For cup holders and / or the larger discarded cups. The cylinder made of the larger plastic sheet is large enough to be installed in the reusable cup holder and / or the larger discard Inside the cup The larger plastic piece may include a mark (such as a dashed line near the bottom), which allows the index to be properly aligned based on whether the larger disposable cup uses the reusable cup holder. When the larger discards When using a disposable cup with a support for a disposable cup, the entire plastic sheet can be used. When the larger disposable cup is used alone (or the reusable cup will not affect alignment, for example, because it does not have a support ), The plastic sheet can be cut at the mark. This allows proper alignment in any case. Β Official use], when I discard the cup, a smaller plastic sheet can be used. In order to provide = ^ 仏 and the comparative Proper alignment of small disposable cups, when measuring fluids, 5 reusable cup holders will generally not be used for this smaller disposable cup. 14 200539951

After the disposable cup 55 is filled with paint, the disposable lid 1 30 is placed on the top of the disposable cup 55. The angle 7 of the outer edge 140 of the disposable lid 130 is substantially equivalent to the angle α of the flange 85 of the disposable cup 55 so that the outer edge 140 of the disposable lid 130 matches the flange 85 of the disposable cup 55 . The angle 7 places the disposable lid 130 in the center of the disposable cup 55. There is no need to increase the total outer diameter of the fluid supply assembly, and the angle τ of the disposable cover 130 also allows for additional sealing areas. A downwardly extending rib 150 on the inside of the disposable lid 130 is mounted in the disposable cup 55. There may be more than one downward extending rib 150 surrounding the disposable cover 130, which surrounds a part of the interior of the disposable cover 130, or the rib may extend completely around. The downward extending rib 150 keeps the disposable cover 130 in place, and it can also serve as a seal. The disposable lid 130 may also have a downwardly extending sealing protrusion 155 that contacts the flange 85 of the disposable cup 55 to enhance sealing.

The reusable outer cover 170 is placed on the top of the disposable cover 130. The connection surface 125 of the reusable cup holder 90 and the complementary connection surface 190 of the reusable outer cover 170 are fastened to the reusable cup holder 90. Suitable connection surfaces and complementary connection surfaces include, but are not limited to, screw connections, shanks and grooves, and tips and slots. The outer edge 180 of the reusable outer cover 170 has an angle 5 of which 15 200539951 is substantially equivalent to the angle of the flange 12o of the reusable cup holder 90. The reusable outer cover 170 is fastened to the reusable Reusable cup holder 9〇 ^ / ° The outer edge 14 of the disposable lid 130 and the flange 85 of the disposable cup 55 are thrown at the temple and are between the outer edge 18 of the reusable outer lid 170 and can be picked up again 1 is between the flange 120 of the cup 90. No need to increase the moment, this angle increases the “foot” force. The angle α of the flange 85 of the disposable cup 55 and the angle γ of the outer edge 140 of the disposable lid can be reused. The angle is less than the angle of the outer edge 180 of the reusable outer cover 170. Generally, each axis is in the range of about 10 ° to about 70 °, usually about 20 ° to about 60 °, and more generally about 30. to about 50 °, more generally about 35. to about 45 °. When the angle α of the flange 85 of the disposable cup 55 and the angle 7 of the outer edge 1 40 of the disposable lid 55 match the fluid The supply assembly is installed at the angle of the paint sprayer, so that the disposable lid system is substantially parallel to the paint axis of the paint sprayer when in use, and almost all the paint in the disposable cup can be used. The cost is more than $ 100 per fluid ounce, reducing paint waste is an important consideration. A plug 235 can be used to cover the joint fitting 160 on the disposable cover 130. The plug 23 can be installed in the joint fitting 160 Inside or outside. The plug 235 will open The port 165 is sealed in the joint fitting 160 for shaking or storage. 16 200539951 In the embodiment, without any additional support, the fluid supply assembly of the present invention is placed in the paint blender machine. The guide 210 is placed into the joint fitting 195 in the reusable outer cover 170. A non-essential filter 22 is inserted into the opening 215 of the catheter 21o. Alternatively, the filter 220 may be placed in The joint fitting 160 of the disposable cover 13 or the joint fitting 195 of the reusable outer cover 170 may have a protrusion 225 if necessary, which prevents the folded disposable cup 55 from blocking. The opening 65 leads to the conduit 21. The protrusion 225 can also be used to remove the filter 220 when the filter 22 is to be cleaned or discarded. If necessary, the conduit 21 can be filled with solvent and cleaned. It is sealed for storage. If an internal fitting fitting plug 235 is used for the fitting fitting 160 on the disposable cup 130, a plug of the same size can be inserted into the catheter. # The fluid supply assembly is installed to the conduit 2 1 0. The catheter 2 1 0 Connects to the reusable outer cover 170 and the paint sprayer 10 and provides a flow path from the interior 75 of the disposable cup 55 to the paint sprayer 10. Various techniques that are familiar with the art can be used Different types of catheters. * For example, an application has been filed on June 10, 2003, entitled "Friction Fit" Paint Cup Connection "in US Patent Application Serial No. i0 / 458,436, which describes a suitable catheter . 17 200539951 Figures 11-15 show another suitable answer 5. The conduit may be a coupler 505 for connection between the paint sprayer 10 and the outer cover 508. The adapter at 505 includes a first end 5m ′ which can be engaged with the paint sprayer 10, as shown in the figure, a second end 515 which can be engaged with the outer cover 508, and—the first end. Hollow perforations 52 between 510 and the second end 515. • In one embodiment, the first end 510 has a diameter smaller than the second end 515. The external shape of the first end 510 is substantially cylindrical. The first end "ο has a connection surface 525 for engagement with the complementary connection surface 530 on the paint sprayer 10. Suitable connection surfaces 525 and complementary connection surfaces 53 include, but are not limited to, tapped spiral surfaces, The handle and the groove, the sharpened connection relationship, the bolt connection relationship, and the crimp connection relationship, or the first end 51 is integrated with the paint sprayer 10, and the adapter 505 is a plug-in sprayer 10 The supply duct. If required, the connection surface 525 and the complementary connection surface 53 for the paint sprayer have threads of representative size and pitch, so the fluid device can be used with any number of sprayers. First end 515 has a portion 535 having a first shape and a portion 540 having a first shape. The portion 535 having a first shape may be flat and the portion 540 having a second shape may be flexed if desired. Or, % The part with the first shape may have a simple or complex shape, including, but ^ is not limited to flexing outward or inward. If the part with the first shape is deflected, it should have a difference from the first Dimorphic The curvature of the shape-like part. The tool 18 200539951 has a shape with a first shape and may have a shape different from the meandering. If necessary, the second end 515 has a flat rim portion 535 and a flexible portion 540 opposite to it. Flexure, and more than one flat portion. If desired, there are two opposing flat portions and two opposing flexures. The outer cover 508 has a generally integrally formed cylindrical joint fitting 555, which has a It passes through its own opening 56. The opening 560 is ring-shaped on the ridge. The opening 550 has at least one tab 555 in the outer cover 508 extending inwardly above the edge of the opening 550. The tab 555 has A shape that allows the first shape portion to pass near it, but does not allow the second shape portion to pass through, allows the first end 515 to be inserted into the opening 550. If a flat portion 535 is used, the tab 555 is generally flat The tab 555 may be at the edge of the upper end of the joint fitting 545, if necessary, or it may be lowered from the edge. Below the tab 555 is at least a horizontal plate 56 in the opening 55. The first 515 has ^ One of the fittings 545 Ping Tam Edition 560 and

The height between the tabs 555 so that the second end 515 only enters the expected distance. When the second end 515 hits the horizontal block 560, the adapter 505 is turned to lock the fluid supply assembly to the paint sprayer 10, as shown in FIG. 15. Alternatively, the outer cover 508 can be rotated onto the adapter 505. When the adapter 505 is turned, the tab 555 is engaged with the top of the flexure 540 of the second end 515. There is at least a vertical stretch plate 562 inside the opening 550. Vertical Block 19

The 200539951 version 562 prevents the adapter 505 from turning excessively until the flat piece 555 matches so that it can be disengaged from the adapter 505. The vertical plate 5 62 can be extended by the plate 555 to a horizontal plate, and the vertical plate 5 62 It extends some distance between the tab 555 and the water. Because the flat portion 535 of the second end 515 and the flat tab 555 of the flexure fitting 545 and the high adapter 505 of the second end 515 cannot be prevented from being connected to the fluid supply assembly due to the connection relationship before they are fully inserted into the opening 550 Improper combination of 5 05 detached. In addition, the second end of the flexure 540 of each side support of the joint fitting 545 reduces the ability of the second end 515 to move inside. This helps to provide a stable connection relationship between the fluid supply components. The disposable cover 565 has a second end 515 of the joint fitting 570 505 entering the joint of the outer cover 508 and the joint fitting 570 of the disposable cover 565 enters the transfer 5 2 0.

The external portion 360 matches the flange 85 of the disposable cup 55. The upwardly extending projection 3 80 is mounted inside the outlet end 65, and the disposable cup 55 forms an additional seal. An alternative embodiment of the disposable cup is shown in Figures 7-10. In Figure 7, the disposable cup 400 has a generally cylindrical lower side wall portion 22 200539951 405, a generally frustum-shaped intermediate side wall portion 415, and a cylindrical upper side wall portion 420. . A big

The exit end 425 of the top of the disposable cup 400 is open, and the portion 430 is closed. The lower side wall portion 405, the intermediate side wall portion and the upper side wall portion 420, the exit end 425, and the bottom portion 430 define a 4 3 5. The interior 4 3 5 is smaller than the interior 7 5. The smaller diameter of the lower sidewall portion when less paint is used allows accurate measurement of the paint ratio. Inside the bottom 415, the exit end 425 defines a shaft 440. A flange 445 extends outwardly and downwardly from the outer edge of the end 425. The flange 445 extends from the thin shaft 44 0 of the outlet at an angle α ranging from about 1 (Γ to about 70 °.) The outlet end 425 is adapted to be placed in the reusable cup holder, and its dimensions are consistent Insert the reusable cup holder.

Alternatively, the generally cylindrical lower side wall portion may be offset from the center, that is, not concentric with the upper side wall portion. This will cause the lower side wall portion to be closer to the side wall of the reusable cup holder, allowing any measurement to be easily read. 4 Figure 8-10, the disposable cup 450 has a generally oval lower side wall portion 4 5 5 And an intermediate sidewall portion 460 extending from the lower sidewall portion to the generally columnar upper sidewall portion 465. The heart depends on the standard. The round shape is round The outlet end 470 of the top of the disposable cup 450 is open, and the bottom 23 200539951 part 4 7 5 is closed. The lower side wall portion 455, the intermediate side wall portion 460 and the upper side wall portion 465, the exit end 470, and the bottom portion 475 define an interior 480. The interior 480 is smaller than the interior 75. Since the disposable cup extends close to the reusable cup holder, the elliptical shape makes it easier to read the index for measuring the coating. The major axis of the ellipse can extend completely or substantially all the way across the diameter of the reusable cup holder, or partially or substantially all the way to the bottom across the diameter®

The exit end 470 defines a shaft 485. A flange 490 extends outwardly and downwardly from the outer edge of the exit end 470. The flange 490 extends from the shaft 485 of the exit end 470 by a distance of about 10 °. To about 70. The angle α of the range extends downward. The outlet end 470 is adapted to be placed in the reusable cup holder so that its dimensions fit into the reusable cup holder. In these embodiments, the distance across the exit end of the disposable cup is greater than the distance across the bottom in at least one direction. A smaller portion of the disposable cup may extend the entire height of the side wall or less than the entire height of the side wall. If the side wall is cylindrical and the smaller diameter portion extends the entire height of the side wall, it can be connected to the flange by a flat annular portion. If it does not extend the entire height of the side wall, it can be connected by an upper side wall portion that is generally frustoconical. Other sidewall configurations known to those skilled in the art can also be used. The disposable cup of this embodiment does not require any modification to the device, and can be used for the reusable cup holder and the outer cover and the disposable cover of the 2005 200551, which allows the use of disposable cups of different sizes in the fluid supply assembly. .
