BACKGROUND OF THE INVENTION

1. Field of the Invention

[001] The invention relates to a liquid strainer, more particularly to a paint strainer, and to a device for storing and dispensing same.

2. Background of the Invention

[002] Disposable paint strainers are used to filter paint that is to be sprayed from a spray gun, and consist of an impervious structure, usually a low-cost paper board body, with a filter insert. The strainer is usually produced in a conical shape, but this shape is not necessarily required. The conical strainer is typically placed in the opening of a spray gun cup and the paint is poured through the strainer and into the cup to filter the paint. Filtering both mixes the paint for best color match and strains any impurities that may clog a spray gun. If a spray gun clogs during use, the uniformity of the painting is compromised. Consequently, virtually all paint manufacturers recommend filtering or straining paint that is used in spray guns. Such pre-filtering is recommended for paint used, for example, in auto body repair.

[003] It is important to protect the strainer body and filter from dust, and to avoid touching the strainer filter with the hand or fingers. Dust can dislodge from the filter mesh, drop into the paint cup and can appear as blemishes on the surface of a car or can clog the spray gun. Touching of the filter can transfer body oils or contaminants on the hand to the filter and can result in spotting or "fish eyes" in the paint job, necessitating repainting. Modern paints, especially waterborne paints, are extremely sensitive to contamination by silicone (dimenthylsiloxide), and touching of the filter must be avoided.

[004] Strainers are typically supplied by the manufacturers in cases of 1 ,000 units.

Internal packages within the case of 1000 strainers are typically bags containing 100 or 250 stacked, nested strainers. Strainers are typically supplied packed in a poly bag or overwrap to prevent contamination. Although satisfactory for transportation of the product, this type of packaging is less than desirable for the paint shop. The bag of strainers must be stored in the paint shop, and the bag can end up on a shelf or a workbench, or even on the floor, where it can be damaged, knocked around or left open. A damaged or open package allows dust to enter the bag, and thus is not desirable. Also, in order to obtain a strainer for use, the painter must reach into the bag and pull out a strainer by hand. If the strainer is dispensed from the bag tip first, the painter is likely to touch and contaminate the outside of the filter.

[005] Over the years, various types of dispensers have been developed to allow for more convenient storage of the strainers. These dispensers have been made from everything from low cost corrugated board to sheet metal. Some conventional dispensers are merely tubes that hold a stack of strainers, and the open ends of the tube do little to avoid exposure of the tip and filter area of the strainer to manual contamination or

contamination from dust in the air. The strainer is typically removed from the top of the dispenser or shipping box, with the painter reaching in to remove a strainer. If the dispenser is mounted at or near chest level, it is difficult to reach into the top of the dispenser, especially when the stack of strainers is almost used and the painter has to reach far down the tube to remove the strainer. To overcome the inconvenience of this, some strainer dispensers have been made with slots down the front side so that the painter can grab the rim of a strainer and move it up the tube and out of the open top end.

However, this slot leaves the carton open to contamination by dust and particles in the atmosphere. Some conventional dispensers are configured to have the strainers dispense from the bottom of the tube, but this has two drawbacks. First, having the strainers dispense from the dispenser bottom leaves the tip and filter of the strainer exposed to the atmosphere, allowing contamination from dust and particulates. Secondly, in order to dispense a strainer from the stack, the strainer is gripped by the tip or filter area of the strainer. This can physically damage the filter or weaken its bond to the paper and/or exposes the filter to contamination from body oils or other chemicals on the hands and fingers.

SUMMARY [006] The subject invention overcomes all the above problems with strainer storage and dispensing.

[007] In one aspect, a liquid strainer is provided which includes a sheet arranged into a hollow conical body by overlapping two edge portions of the sheet and joining the edge portions within the overlapped area. The conical body includes a rim and an apex. The conical body defines at least one cut out portion. The liquid strainer further includes a filter overlying an interior surface of the conical body and covering the at least one cut out portion, and a protruding tab disposed on an external surface of the conical body between the apex and the rim, the tab protruding outside the overlapped area from one of the edge portions.

[008] The liquid strainer may include one or more of the following features: The tab extends along a line between the apex and the rim. The tab is formed integrally with the conical body. The tab comprises a first side, a second side opposed to the first side, and a peripheral edge that joins the first and second sides, the tab being contiguous with the conical body along a portion of the peripheral edge. The tab is configured to be movable between a first orientation in which the first side of the tab confronts and overlies the exterior surface of the conical body, and a second orientation in which the second side of the tab confronts and overlies the exterior surface of the conical body. The tab is configured to move relative to an operating configuration in which the first and second sides are substantially normal to the exterior surface of the conical body. The conical body is formed of a thin imperforate material. The conical body is formed of one of paper, paperboard and plastic conical body and tab are formed from a single blank of material. The tab is formed separately from the conical body.

[009] In another aspect, a dispenser comprises an elongate hollow dispenser for storing a nested stack of strainers and dispensing individual strainers from the stack, each strainer having a dispensing tab, the dispenser including opposed first and second ends, the second end configured to expose at least the dispensing tab of the strainer extending from the second end of the for removal of a single strainer from the dispenser. [010] The dispenser may include one or more of the following features: The dispenser includes a skirt configured to permit selective opening and closure of an opening in the skirt and withdrawal of a strainer through the opening For example, the skirt can include a door configured to permit the selective opening and closure of an opening in the skirt and withdrawal of the strainer through the opening. The skirt is hollow and includes a skirt base portion connected to the second end of the dispenser body, the skirt base portion being semi-circular in cross-sectional shape, a skirt apex portion opposed to the base portion, and a skirt wall portion extending between the skirt base portion and the skirt apex portion. The door includes a door base portion connected to the second end of the dispenser body, the door base portion being an arc in cross-sectional shape, the arc angle being in the range of 190 degrees to 300 degrees, a door apex portion opposed to the door base portion, and a door wall portion extending between the door base portion and the door apex portion. The door is rotatable about a longitudinal axis of the dispenser. When the door is in a closed position, the door and the wall portion of the skirt provide the skirt with a conical shape. The dispenser includes a flattened portion that is configured to be wall mounted. The dispenser includes a stand member configured to support the dispenser relative to a horizontal mounting surface. The dispenser is configured to dispense strainers in a predetermined orientation relative to a longitudinal axis of the strainer and an axis transverse to the longitudinal axis.

[011] In another aspect, a method of using a dispenser to store a stack of conical strainers and to dispense individual strainers from the dispenser is provided. The dispenser includes an elongate hollow dispenser body including opposed first and second ends. The method includes loading stacked and nested conical strainers into the interior of the cylindrical body by inserting the stack into the cylindrical body such that the apex of a leading strainer is first in, and such that the loaded strainers are positioned in the dispenser such that at least the apex of the leading strainer extends through an opening in the second end of the dispenser body. The method includes dispensing the leading strainer separately from the remaining stacked strainers by engaging a tab located on the outer side surface of the leading strainer, the tab disposed between the apex and a rim of the leading strainer. The method further includes removing the leading strainer from the dispenser using the tab.

[012] The method may include one or more of the following features: The dispenser further having a skirt configured to close the second end, the skirt including a door configured to permit selective opening and closure of an opening in the skirt, and the step of dispensing further comprising opening the door, engaging the tab located on the outer side surface of the leading strainer, removing the leading strainer from the dispenser through the door, and closing the door. The step of dispensing further includes manually grasping the tab, and then pulling downward on the strainer via the tab while rotating the apex radially outward, thereby withdrawing the leading strainer from the dispenser.

[013] The subject invention provides a strainer having a dispensing tab, located on the outer surface of the strainer, which provides a manual grip area that allows the strainer to be withdrawn from its packaging or from a dispenser while avoiding direct contact with the strainer body or filter. Furthermore, the subject invention can be provided at no additional cost of material or labor during the manufacturing of the strainer.

[014] If the strainer is packed in the traditional poly bag or poly tubing, the dispensing tab of the strainer can be can be conveniently grasped by the painter for removal from the stack within the bag. Furthermore, the removal will be from the tip end, which provides for easier removal than if the strainer is de-nested from the rim at its open end, in which case the rim or tabs on the strainer can catch in the soft plastic bag or film and interfere with removal.

[015] The subject invention also includes a dispensing unit which can be loaded with multiple stacked strainers, and allows the dispensing tab to be gripped for dispensing of the strainer from the bottom of the dispenser without direct contact with the filter portion of the strainer. The bottom-dispensing feature is more convenient than some

conventional top-dispensers, allows complete protection of the strainer during storage, and includes a closable lower end through which the strainer is removed without direct contact of the tip and filter area.

[016] Modes for carrying out the present invention are explained below by reference to an embodiment of the present invention shown in the attached drawings. The above- mentioned object, other objects, characteristics and advantages of the present invention will become apparent from the detailed description of the embodiment of the invention presented below in conjunction with the attached drawings.

DETAILED DESCRIPTION

[035] Referring now to Fig. 1, a disposable liquid strainer 10 is shown which includes a hollow, conical body 14 having an open, generally circular end defined by a rim 16. The conical body tapers to an apex 18 that is opposed to the rim 16. The rim may include rim tabs 22, 24 that permit positioning and support of the strainer 10 or allow removal of the strainer from a spray gun cup by an area free of paint. The rim tabs 22, 24 extend outward from the rim 16 so as to extend the exterior surface 28 of the conical body 14. The rim tabs 22, 24 serve as handles by which the strainer 10 can be held and positioned, and each includes a through hole 26 by which the strainer can be secured to a stand if desired. The strainer 10 is provided with a filtering region 70 in the vicinity of the apex 18 that includes side filter areas 72 and an apex filter area 74.

[036] In addition, the strainer 10 is provided with a dispensing tab 40 which protrudes from an exterior surface 29 of the strainer 10 along a line L extending between the apex 18 and the rim 16. The dispensing tab 40 permits the exterior of the strainer 10 to be manually grasped to facilitate removal from packaging or other storage means, while avoiding direct contact with conical body 14, and particularly avoiding contact with portions of the filtering region 70 including the filter areas 72, 74.

[037] Referring now to Fig. 2, the preferred embodiment of a blank for forming the disposable conical strainer 10 is illustrated generally at 12 and has a sheet body 12A with a first convex leading edge 30 and a second trailing substantially concave edge 31 extending between sides 34 and 36. When the blank 12 is formed into a cone, the convex edge 30 and sides 34, 36 together define the rim 16, and along with the concave edge 31 define the apex point 18 opposed to the rim 16. The sheet body 12Amay further include the rim tab portions 22 and 24 formed at the respective intersections of sides 34, 36 and the convex edge 30. [038] The concave edge 31 is divided into two edge portions 32 and 33 which extend substantially from the apex 18 outwardly to the edge formed by sides 34 and 36. One of the edge portions 32 includes a protrusion which forms the dispensing tab 40. The dispensing tab 40 is integral with the sheet body 12A and protrudes from a generally central portion of the edge portion 32. More particularly, as better seen in Fig. 1, the dispensing tab 40 protrudes from the edge portion 32 at a location between the filtering region 70 and the rim 16. Although not limited to this location, placement of the dispensing tab 40 between the filtering region 70 and the rim 16 avoids likelihood of contact between a user's fingers and the filtering region. In the illustrated embodiment, the dispensing tab body is formed integrally with the sheet body 12 A, but it is obvious to those skilled in the art that it may be a separately added member consisting of any material and be of any shape to perform the function of the invention. In the illustrated embodiment, the dispensing tab 40 is generally rectangular in shape, but the dispensing tab 40 is not limited to this shape.

[039] Cutouts 20 are formed in the sheet body 12A near the concave edge 31 , and are generally sector- shaped. The cutouts 20 define the side filter areas 72. In addition, a substantially circular opening 21, which is formed in the sheet body 12A so as to intersect the concave edge 31 at its midpoint, corresponds to the apex filter area 74. Through holes 26 are formed in the rim tab portions 22, 24.

[040] The sheet body 12A material is preferably formed of a thin imperforate sheet material and can be for example kraft board, sulphate board, coated or non-coated paper or other materials resistant to paint or other liquids to be filtered.

[041] A filter material strip 50 in the form of a mesh blank overlies the cutouts 20 and opening 21, and is glued to the body sheet material at marginal edge portions of the cutouts 20 and opening 21. The filter mesh material 50 can be any suitable screening material known in the art such as textile mesh of sufficient mesh size to filter the particulate material processed in any particular use. Synthetic, textile, metallic and other mesh materials can be used. The pore sizes of the mesh can vary according to the nature of the paint and the desired finish and can, for example, be in the range of 80 to 500 microns or can be formed of a suitable non- woven fabric such as a lightweight spunbonded polypropylene or polyester fabric.

[042] Folding the sheet body 12 into the final conical strainer 10 is accomplished by positioning edge portion 32 over a margin portion of edge 33 and adhering the overlapped area 62, shown in cross-hatch in Fig. 1, from the apex 18 up to the upper edge, or rim, 16 of the conical strainer 10. Here, the edge portion 32 overlies the margin portion of edge 33 so as to reside on an exterior surface 29 of the strainer 10.

[043] In addition, the dispensing tab 40, which protrudes from the edge portion 32, is not adhered to the margin portion of edge 33, and instead is free standing and foldable about the line L corresponding to the joint between the dispensing tab 40 and the edge portion 32. That is, the dispensing tab 40 includes a first broad side 42, a second broad side 44 opposed to the first side, and a peripheral edge 46 that joins the first and second sides 42, 44, such that the dispensing tab 40 is contiguous with the conical body 14 of the strainer 10 along a portion of the peripheral edge 46 that corresponds to the line L. Due to the flexibility of the sheet body material, the dispensing tab 40 is movable about the fold line between a first orientation in which the first side 42 of the dispensing tab 40 confronts and overlies the exterior surface 29 of the conical body 14, and a second orientation in which the second side 44 of the dispensing tab 40 confronts and overlies the exterior surface 29 of the conical body 14 (Fig. Ia). In use, the dispensing tab 40 is generally oriented so as to protrude from the exterior surface 29 and the first and second sides 42, 44 are substantially normal to the exterior surface 29.

[044] Adhesion of the overlapped area 62 can be achieved using glues of the aqueous emulsion type. By maximizing the overlapped area 62, good adherence can be obtained. Moreover, the maximized area 62 further provides a somewhat rigidified doubled over portion which adds mechanical strength and forms a rib which aids in supporting the paint or other material strained. [045] In an embodiment of this invention, the strainer 10 has a diameter of

approximately 6 inches at the rim 16, and the distance from the apex 18 to rim 16 is about five and one-quarter inches. The side cutout portions 20 define filter areas of 3-3/10 square inches each and the apex filter area 74 is generally conical with an area of 3/10 square inches and an overlapped, multi-ply area 64 of 1/10 square inch. Preferably the ratio of area 64 to the area of the conical apex filter mesh material is at least one to three. However, these dimensions are merely illustrative, and the invention is not limited thereto.

[046] It should be understood that any number of cutout portions 20, 21 may be used as desired. An advantageous feature of the invention is the use of an apex filter 74 which enables maximized straining without wastage of material and with sufficient mechanical strength to enable straining under severe conditions of use as in paint straining and the like. Although the apex filter 74 is generally conical, the upper edge of the strainer 10 can be circular as in the preferred embodiment, star-shaped or have irregular shaped as may be desired for particular applications.

[047] Referring now to Figs. 3-13, a dispenser 100 is used to store multiple stacked, nested strainers 10, and to dispense individual strainers 10 from the lower end of the stack. With particular reference to Figs. 3 and 4, the dispenser 100 includes an elongate hollow dispenser body 102 including opposed first and second ends 104, 106. In the illustrated embodiment, the dispenser body 102 is substantially cylindrical, and in use is generally oriented so that a longitudinal axis 101 of the body 102 is vertical and the first end 104 overlies the second end 106. The inner diameter of the dispenser body 102 is slightly greater than the outer diameter of the rim 16 of the strainer 10.

[048] The dispenser body 102 is formed by joining two half cylinders (Figs. 5-6). The first half cylinder corresponds to a front half 108 of the dispenser body 102, and the second half cylinder corresponds to the rear half 110 of the dispenser body 102. The half cylinders are joined along longitudinally extending edges which include radially outward extending flanges 112, 114. Specifically, the flanges 112 of the front half 108 are provided with one or more circumferentially extending connecting tabs 116. In addition, the flanges 114 of the rear half 110 are provided with corresponding connecting slots 118 dimensioned to receive the connecting tabs 116. When the two half cylinders are placed together so that the front half flanges 112 abut the rear half flanges 114, the connecting tabs 116 are received in corresponding connecting slots 118. The connecting tabs 116 may be press fit into the slots 118. In addition, fasteners such as clips 120 may be used to secure the respective the front and rear halves 108, 110 of the dispenser body 102 in a joined, cylindrical configuration.

[049] In addition, the rear half 110 of the dispenser body 102 includes a flat, centrally disposed back panel 130 formed by providing body 102 with a stepped out portion. The flat back panel 130 provides a stable mounting surface that includes at least one through hole 132 to permit the dispenser 100 to be wall mounted. The through hole 132 may be elongated, and may include a widened portion sized to receive a fastener head

therethrough.

[050] Referring again to Figs. 3 and 4, the first end 104 of the body 102 is open, and is provided with a removable cover 180 that closes the first end 104 and prevents dust and debris from entering the dispenser 100 through the first end 104. A rear edge of the cover 180 is pivotably connected to a rear edge of the first end 104. The pivotable connection is achieved by any conventional means, and may include providing a curved member 182 on the rear edge of the cover 180 which passes through and engages with slots 138 formed in the back panel 130 of the dispenser body 102.

[051] The second end 106 of the body 102 is partially closed by a domed skirt 140 that extends axially from the second end 106, and which is semi-circular in cross-section (Figs. 7 and 8). The skirt 140 is provided on a rear half of the dispenser body 102, such that the front half of the lower end of the dispenser is open. This opening is identified in the figures at 148.

[052] As best seen in Fig. 9, the skirt 140 includes a cylindrical portion 143 that extends integrally from the second end 106, and terminates in a tapered portion 144 that is tapered from the cylindrical portion 143 to a skirt apex 145. The cylindrical portion 143 includes a circumferential, outward protruding lip 142 disposed near the second end 106, forming a circumferential groove 146 between the second end 106 and the lip 142. The groove 146 is used to connect a rotatable skirt door 150 to the skirt 140, as discussed further below.

[053] The domed skirt door 150, having a shape that substantially conforms to that of the skirt 140, overlies and surrounds at least a portion of the skirt 140. The skirt door 150 is sector shaped in cross section such that the arc angle θ of the sector is greater than 180 degrees (Fig. 10). The sector arc angle θ is required to be at least slightly greater than 180 degrees so that when the skirt door 150 is in a closed position relative to the skirt 140, the skirt door 150 completely closes the opening 148 at the front half of the lower end 106 of the dispenser 100, as so that the sides edges of the skirt door 150 overlie opposed sides of the skirt 140 (Fig. 3). In the illustrated embodiment, the sector arc angle θ is approximately 210 degrees, but the sector arc angle θ may be in the range of 182 to 300 degrees. This sector arc angle θ is sufficient to permit selective opening and complete closure of the front opening 148, while also permitting withdrawal of a strainer 10 through the opening 148.

[054] Referring to Figs. 9 and 11, the skirt door 150 includes a skirt door apex 160 that surrounds the skirt apex 145 such that the skirt apex 145 is nested within the skirt door apex 160. The skirt door 150 includes a cylindrical portion 152 disposed adjacent to the second end 106, and a tapered portion 154 that is tapered from the cylindrical portion 152 to the skirt door apex 160. The cylindrical portion 152 includes a circumferential, inward protruding lip 156 disposed near the second end 106. The skirt door lip 156 is received within and engages the groove to retain the skirt door 150 on the skirt 140. The lip 156 is sized and shaped to permit the skirt door 150 to slide over the outer surface of the skirt 140 while rotating about the longitudinal axis 101 of the dispenser body 102 between an open position (Fig. 4) and a closed position (Fig. 3). [055] In the open position, the skirt door 150 is rotated to a position substantially on the rear of the dispenser 100 so that opening 148 on the lower end 106 of the front of the dispenser 100 is open, and the skirt door 150 completely surrounds the entire skirt 140.

[056] In the closed position, the skirt door 150 is rotated to a position substantially on the front of the dispenser 100 so that the opening 148 is closed, and only the margin portions of the edges of the skirt door 150 overlie laterally opposed sides of the skirt 140. In the closed position, the skirt door 150, in combination with the skirt 140, closes the opening 148 at the second end 106 and prevents dust and debris from entering the dispenser 100 through the opening 148. In some embodiments, the skirt door 150 may be transparent, whereby it is possible to view the strainers 10 loaded in the dispenser 10 through the skirt door 150, even when the skirt door 150 is in a closed position.

[057] The diameter of the respective cylindrical portions 143, 152 of the dispenser 100 is less than that of the second end 106 of the cylinder body 102, and is slightly less than the diameter of the rim of the strainer 11. As a result, a shoulder 134 is formed on the inner surface of the dispenser 100.

[058] In addition, a handle 162 is formed on the outer surface 158 of the tapered portion 154 of the skirt door 150. The handle 162 is a thin plate that protrudes radially outward from the outer surface 158, and extends along a line between the skirt door apex 160 and cylindrical portion 152. The handle 162 can be easily manually grasped and used to rotate the skirt door 150 relative to the skirt 140 about the longitudinal axis 101 of the dispenser 100.

[059] Referring to Fig. 12, a stack 80 of nested strainers 10 are shown disposed in the dispenser 100. The stack 80 is loaded into the dispenser 100 through the open first end 104 with the strainers 10 in an upright orientation such that the apices 18 of the strainers 10 are downward, and the respective rims 16 reside above the apices 18. When the strainers 10 are loaded into the dispenser 100, the lower-most strainer 10 is supported on the shoulder 134 so that rim 16 and portions of the conical body adjacent the rim 16 are disposed within the cylinder body 102 of the dispenser. Correspondingly, the remainder of the strainer 10, and particularly the filtering portion 70, extends below the cylindrical body 102 and resides within the skirt 140. In this configuration, when the skirt door 150 is in the open position, the forward facing side of the lower portion of the strainer 10 is exposed to the exterior (Fig. 4).

[060] The rim tabs 22, 24 of the strainer 10, having an outer dimension greater than the diameter of the rim 16 and of the cylinder body 102, are received within the interior channel 122 formed by the joined front and rear flanges 112, 114. As a result, the strainer 10, when disposed within the dispenser 100, is constrained to a particular orientation relative to its longitudinal axis 11. That is, when the rim tabs 22, 24 are received within the channels 122, the dispensing tab 40 can be oriented to face the opening of the skirt 140. Thus, the dispenser 100 is configured to dispense strainers 10 in a predetermined orientation relative to the longitudinal axis 11 of the strainer 10. In addition, since the dispenser 100 maintains the strainer in an upright orientation with the apex 18 disposed below the rim 16, the strainer is also constrained to a predetermined orientation about an axis transverse to the longitudinal axis 11.

[061] The dispenser 100 permits storage of one or more strainers 10, and when storing the strainers, the dispenser can be fully closed so that the strainers 10 are protected from environmental dust and debris. In addition, the dispenser 100 includes a closable door 150 that can be selectively opened and closed to permit access to the opening 148 formed in the lower end 106, through which individual strainers 10 can be dispensed.

[062] Referring to Fig. 13, in addition to having features which permit it to be wall mounted, the dispenser 100 may also include a stand 200, which allows the dispenser 100 to supported in an upright orientation relative to a horizontal mounting surface such as a counter top. The stand 200 includes a base 202 and a sleeve 204 which extends upward from the base 202. The base 202 is generally U-shaped, and is oriented to open to a side corresponding to the front of the dispenser 100. The sleeve 204 includes an extension portion 208 extending upward from the base 202, and an annular portion 206 mounted to the top of the extension portion 208. The annular portion 206 is closed in cross section so as to form a ring in which the dispenser 100 is received and supported (Fig. 16). In addition, like the base 202, the extension portion 208 is a plate member formed into a U- shape that opens to the front.

[063] As seen in Figs. 14 and 15, the sleeve 204 is formed having a peripheral shape that conforms to the shape of the dispenser body 102, and includes opposed sleeve side channels 218 which are sized and shaped to receive the flanges 112, 114 of the dispenser body 102 therein. A sleeve rear channel 220 is provided on a rearward side of the sleeve 204 which is sized and shaped to accommodate the back panel 130 of the dispenser body 102. The sleeve rear channel 220 is provided with a slightly circumferentially inward taper 222 so that the upper end 220a of the sleeve rear channel 220 is wider than the lower end 220b. The taper 222 is dimensioned to match a corresponding taper 135 formed on the back panel 130 of the dispenser body 102.

[064] In use the dispenser 100 is received within the sleeve 204 so that a front of the dispenser 100 faces forward, and the annular portion 206 surrounds the lower end of the dispenser 100. In addition, the flanges 112, 114 of the dispenser 100 are received in the sleeve side channels 218, and the back panel 130 is received in the sleeve rear channel 220. The respective tapered surfaces 135, 222 of the dispenser 100 and annular portion 206 engage, whereby the dispenser 100 is maintained within the stand 200 at a predetermined height above the horizontal mounting surface.

[065] Amethod of using the dispenser 100 to store a stack of conical strainers 10, and to dispense individual strainers 10 from the dispenser 100, will now be described. The method includes the following steps:

[066] Step 1. Loading stacked and nested conical strainers 10 into the interior of the cylindrical body 102 by inserting the stack 80 into the cylindrical body 102 such that the apex 18 of a leading (lower-most) strainer 10 is first in. The loaded strainers 10 are positioned in the dispenser such that at least the apex 18 of the leading strainer 10 extends beyond a second end 106 of the cylindrical body, and is at least partially surrounded by the skirt 140 and skirt door 150. In addition, the loaded strainers are positioned in the dispenser such that the rim tabs 22, 24 reside within the channels 122, and the dispensing tab 40 is disposed in the opening 148. This orientation of the strainer 10 within the dispenser 100 conveniently makes the dispensing tab 40 easily accessible when the skirt door 150 is rotated to an open position. Although the strainer 10 can be inserted into the dispenser 100 in other orientations, for example in an orientation in which the rim tabs 22, 24 do not reside within the channels 122, placement of the rim tabs 22, 24 within the channels 122 advantageously promotes centering of the dispensing tab 40 in the opening 148.

[067] During storage of the strainers 10, the cover 180 for the upper end of the dispenser and the skirt door 150 are closed, providing a closed storage device and preventing dust and debris from contacting and contaminating the strainers 10.

[068] Step 2. Open the skirt door 150 from the closed position (Fig. 3) to the open position (Fig. 4) to provide access to the leading strainer. Of course, this step can be skipped in the event that the skirt door 150 was already in an open position.

[069] Step 3. Dispensing the leading strainer 10 separately from the remaining stacked strainers 10. This is achieved by:

Step 3a. Manually grasping the dispensing tab 40 that is located on the outer side surface of the leading strainer 10a, and then

Step 3b. Using the dispensing tab 40 to pull downward on the strainer 10 while rotating the apex 18 radially outward, withdrawing the leading strainer

10 from the dispenser.

[070] Because the dispensing tab 40 is on the exterior surface 28 of the strainer 10, the dispensing tab 40 can be grasped and the strainer dispensed with a lateral motion, allowing on the strainer 10 to come free of the stack and be dispensed. [071] Because the dispensing tab 40 is on the exterior surface 28 of the strainer 10, there is no need to contact the conical surface 14 of the strainer 10, and any contact with the filter region 70 can be avoided.

[072] Use of the dispensing tab 40 to grasp the strainer 10 allows only one strainer to be dispensed at a time, and protects the filter portion 70 of the strainer. In contrast, if the strainer were to be dispensed without the dispensing tab 40, grasping the conical body 14 by pinching of the tip or mesh could damage or contaminate the filter portion 70. In addition, it is difficult to grasp the conical body directly while controlling the pinching tension, and pinching often results in more than the one strainer 10 being dispensed.

[073] Step 4. Close the skirt door 150 to ensure that the remaining strainers 10 are stored and maintained in a non-contaminated condition.

[074] Although the dispenser 100 is configured to accommodate the features of strainer 10, it is understood that other strainer configurations including strainers having no rim tabs 22, 24 can be stored in, and dispensed using, the dispenser 100.

[075] A selected illustrative embodiment of the invention is described above in some detail. It should be understood that only structures considered necessary for clarifying the present invention have been described herein. Other conventional structures, and those of ancillary and auxiliary components of the system, are assumed to be known and understood by those skilled in the art. For example, instead of manually gripping the dispensing tab, it would be obvious to those skilled in the art to design a lever that could contact the dispensing tab and push the strainer downward, allowing it to drop free of the dispenser. Moreover, while a working example of the present invention has been described above, the present invention is not limited to the working example described above, but various design alterations may be carried out without departing from the present invention as set forth in the claims.
