Boyd, West Allis, Wis., assignor to Gritlith-Hope Company, West Allis, Wis., a corporation of Wisconsin Filed Sept. 20, 1963, Ser. No. 310,198 8 Claims. (Cl. 221-279) This invention relates to dispensers for nested articles, such as disposable drinking cups and the like made of paper or thin plastic material.

Cups of this type are manufactured in a wide range of sizes, and it has been common practice to provide a dispenser for each cup size or for a relatively narrow range of cup sizes.

An object of the invention is to provide an improved cup dispenser capable of accommodating and dispensing stacked paper cups and the like having a relatively wide range of rim diameters so as to avoid the need for supplying numerous sizes of dispensers.

Another object is to provide a cup dispenser which includes simplified and improved means for forming a restricted dispensing throat capable of automatic adjustment to accommodate and retain the various-sized cups and to insure individual delivery of the cups.

Still another object is to provide a cup dispenser which includes a dispensing throat formed by a plurality of superposed centrally open throat disks of inexpensive construction having inwardly projecting resilient cup-retaining tongues or blades, and which further includes simplified and improved means for mounting the throat disks.

A further object is to provide a cup dispenser which will accommodate both frusto-conical and fully conical cups, as well as dishes, bowls, and the like, and which can be arranged as a downfeed dispenser or an upfeed dispenser.

A further object is to provide a cup dispenser in which the dispensing parts can be inexpensively constructed of plastic material.

A further object is to provide a cup dispenser including means for resisting retrograde movement of the stacked cups during dispensing by a pick-up or gripping-type cup holder, and in which said means is rendered ineffective during loading of the dispenser.

The invention further consists in the several features hereinafter described and claimed.

Referring to the drawings, the downfeed cup dispenser illustrated in FIGS. 1 to 6 is designated generally by the numeral 20 and includes a vertically extending tubular casing 21 of cylindrical shape forming a magazine for housing therein a stack of nested disposable cups 22, such as of paper or plastic. These cups, here shown to be of a conventional frusto-conical type, have resilient side walls 23 and resilient beaded rims 24, the rims of adjacent nested cups being axially spaced. The tubular casing 21, which is formed of sheet metal or other suitable material, has an open upper end for loading the stacked cups therein, and normally closed by a skirted domed cap or cover member 25. The inner diameter of the casing is selected to accommodate the largest-sized cups to be dispensed. The lower end of the casing is provided with an enlarged throat-forming cup-dispensing head designated generally by the numeral 26 and hereinafter described. The casing is equipped with the usual vertically extending inspection window 27 in the lower portion of its side wall. For wall mounting of the dispenser, the casing is provided with one or more of the usual wedgetype flange members 28 detachably interengageable with wall brackets 29.

The dispensing head 26 comprises an annular end fitting or adapter 30 and a cap ring 31 detachably secured thereon, as hereinafter described, for mounting a pair of

throat disks

32 and 33, hereinafter described, arranged in superposed relation coaxially of the tubular cup casing 21. The end fitting 30, which is desirably formed of molded plastic such as polyethylene, includes a sleeve portion 34 snugly fitting over the lower end portion of the tubular casing and rigidly attached thereto, as by rivets 35, the lower end of the sleeve portion having an internal annular shoulder 36 against which abuts the lower edge of the tubular casing. The end fitting 30 further includes an outwardly projecting flat ring portion 37 integrally joining the outer end of the sleeve portion, and a downwardly projecting cylindrical ring portion 38 integrally joining the outer edge portion of the fiat ring portion. Peripherally spaced radial ribs 39 at the inner side of the cylindrical ring portion integrally connect this ring portion and the fiat ring portion 37, the lower edges of these ribs being coplanar with the bottom edge of the cylindrical ring portion. The outer periphery of the cylindrical ring portion 38 is provided with projecting segmental screw threads 40, and the outer bead-like edge of the flat ring portion 37 presents a downwardly facing bevel seat 41. The cap ring 31, which is also formed of molded plastic, such as polyethylene, is detachably screwed onto the end fitting 30 and comprises a cylindrical ring portion 42 and an inturned annular bottom or end flange 43. The cylindrical cap ring portion 42 is provided at its inner side with segmental threads 44 engageable with the external threads 40 of the end fitting 30, and the upper periphery of the cap ring portion 42 has a bevel seat 45 engageable with the bevel seat 41 of the end fitting.

The

flat throat disks

32 and 33 are marginally clamped between the inturned flange 43 of the cap ring and the annular lower edge of the end fitting 30, the upper disk 32 engaging a flat gasket ring 46 of resilient plastic, such as polyethylene, which bears against the lower edge of the end fitting and the lower edges of the ribs 39. The gasket ring 46 is somewhat thicker than the throat disks. The cap ring flange 43 has integrally formed on its inner face a pair of diametrically opposite dowel projections 47 extending parallel to the axis of the cap ring. The dowel projections pass through holes 48 formed in the throat disks and into holes 49 formed in the gasket ring, the latter ring being pressed onto the dowel projections so that the throat disks will remain on the cap ring when it is unscrewed from the end fitting 30.

The normally

flat throat disks

32 and 33 are desirably formed of a thin resilient material, preferably a plastic such as polypropylene, polytetrafluoroethylene, and acetate resin, and are conveniently stamped out of fiat sheet stock or are molded to shape. Each throat disk has a star-shaped central opening or aperture 50 defined by evenly spaced inwardly projecting radial tongues or blades 51 of inwardly tapering shape, eight tongues or blades being provided in the present instance, and the inner ends of the inwardly divergent spaces 52 between the inner ends of the blades being about equal to the width of the blades. The edges of the inner ends of the blades are here shown to be slightly concave. The inner diameter of the opening in the outer disk 33, that is, the distance between the inner ends of opposite tongues, is slightly smaller than the cup diameter of the smallest cup 22a to be dispensed at a region immediately adjacent to the underside of the rim bead, so as to compensate for sagflexing when a full column of cups is loaded, and the inner diameter of the opening in the inner disk 32 is slightly larger than that of the outer disk, a difference of about inch in these diameters being found suitable. As seen in full lines in FIG. 2, the inner ends of the tongues or blades of the upper or inner throat disk 32 engage the side walls and the underside of the resilient rim of the lowermost cup, and the inner ends of the tongues or blades of the outer disk 33 engage the tapered side walls of the cup at a region spaced downwardly from the rim, thus supporting and retaining the stack of cups. In the case of

cups

22b and 220 with larger rim diameters, as indicated by broken lines in FIG. 2, the cupretaining tongues of the two throat disks assume downwardly deflected stack-retaining positions.

When the cup dispenser is to be loaded, the casing cover 25 is temporarily removed and a stack of cups is lowered into the casing. In the case of the smaller-sized cups the lowermost cup will freely enter the central openings in the throat disks until it is stopped by the inner ends of the dispensing tongues 51, while in the case of cups 22c, FIG. 2, with a bottom diameter larger than the normal gap between opposed tongues, the weight of the stack of cups or additional downward pressure on the stack will deflect the tongues downwardly and force the lowermost cup through the throat disks a sufficient distance so that it can be grasped by the users fingers. In some instances, the user may insert his fingers upwardly into the throat disk openings to pull the lower portion of the lowermost cup into the disk openings to dispensing position.

When the lowermost cup is to be withdrawn from the dispenser, it is grasped at its protruding lower portion by the users fingers and pulled downwardly, further deflecting the dispensing tongues of the throat disks until the cup is released from these tongues. During the withdrawal of the lowermost cup, the resilient rim of the lowermost cup passes through the two throat disks in succession and may temporarily bulge slightly into the inter-tongue spaces of the throat disks. During this withdrawal, the following cup is drawn downwardly by the frictional engagement between the cups a short distance but is restrained against withdrawal by the tongues of the upper or inner throat disk 32, thus separating the cups. This momentary condition is illustrated in FIG. 6. After the lowermost cup is free of the dispenser the tongues snap back to the cup-retaining position seen in FIG. 2. When dispensing the larger cups, the flexing action of the throat disks is much more pronounced, but operation and separation is equally effective.

The cup dispenser illustrated in FIGS. 7 to 9 is arranged for upfeed dispensing of frusto-conical paper cups 22, and is adapted for mounting on a counter or table top 55 having an opening 56. The dispenser includes a tubular casing 71 the upper portion of which extends through the counter opening 56 and is provided with a dispensing head 76. The dispensing head includes an end fitting similar to the fitting 30 of FIG. 1 except that the flat ring portion 37 thereof is provided with an added peripheral flange 57 of curved outwardly tapered cross-section having a thin outer edge 58 adapted to be flexed tightly against the counter top to provide a moisture seal. As in FIG. 2, the dispenser is provided with a cap ring 31 detachably screwed onto the end fitting 80 and mounting a pair of

stacked throat disks

32 and 33 and an annular gasket 46. The casing 71 is fixed in position by a surrounding split ring 59 which is formed in one or two parts and attached thereto by one or more clamping screws 60 and which engages the underside of the counter top. A peripherally flanged cover 61 is secured in the lower end of the casing as by sheet metal screws 62.

A domed cup follower 63 of frusto-conical shape is axially movable in the magazine and is urged upwardly, as by a conical coil spring 64. The upper end of the cup-elevating spring is secured to the follower by a clip 65 riveted to the follower, and the lower end of the spring is secured to the bottom cover 61 of the casing by a riveted clip 66.

To load the dispenser of FIG. 8, the throat-carrying cap ring 31 is unscrewed from the end fitting 80, whereupon a stack of the inverted nested cups 22 is pushed downwardly into the casing against the pressure of the elevator spring 64, the rim of the lowermost cup bearing on the cup follower 63. While the cup stack is held depressed, the cap ring is screwed back onto the end fitting, and the cup stack is then permitted to rise slightly to bring the uppermost cup into engagement with the dispensing tongues. Alternatively, the throat-carrying cap ing 31 may be engaged about the uppermost cup to assist in pushing the cup stack into the container.

The upwardly urged stacked cups are retained by the resilient tongues 51 of the

throat disks

32 and 33 the inner ends of which engage the walls of the outermost or uppermost cup in the same manner as in the downfeed dispenser of FIG. 2, and individual withdrawal of the cups from the dispenser is effected in the same manner.

The downfeed dispenser shown in FIGS. 10 to 13 is generally similar to that of FIG. 1 but is slightly modified for dispensing nested conical paper cups 122, either directly by hand or by means of a pick-up or grippingtype cup holder H, FIG. 10. The dispenser includes a dispenser head 126 having therein a pair of

throat disks

132 and 133 which are similar to the

throat disks

32 and 33 of FIG. 5 except that in forming the central opening of each disk alternate resilient tongues are omitted, leaving wider spaces 152 between the remaining four tongues 151. The throat disks are mounted in the dispenser head 126 in the same manner as in the dispenser head 26 of FIG. 2 and will accommodate a wide range of cup sizes. Stacked cups 122a of relatively small size are shown by full lines in FIG. 11, and cups 122b and 122c of considerably larger size are indicated in broken lines. Each of the cups has a resilient conical side wall 123 and a resilient rim bead 124.

A follower weight 164 is movable in the tubular casing 21 and includes a downwardly projecting bar 163 engaging the inner walls of the uppermost cup, as seen in FIG. 11. The weight is connected by a retaining chain 165 to the center of the underside of the removable casing cover 25.

The stacked cups are loaded into the casing from above and are urged downwardly by the follower weight, the pointed lower ends of the lowermost cups projecting through the central openings of the throat disks. As shown by full lines in FIG. 11, the deflectable resilient tongues 151 of the

throat disks

132 and 133 engage the outer walls of the lowermost cup 122a to retain the stack of cups in the dispenser; and in the case of cups with larger rim diameters, the dispensing tongues will assume a normal downwardly deflected position as shown by broken lines.

When the first or lowermost cup is withdrawn downwardly, either directly by hand or by means of the pickup or gripper-type holder H of FIG. 10, the resilient rim portion of the cup is forced past the inner ends of the resilient tongues 151 of the two throat disks in succession, deflecting these tongues downwardly, and parts of the resilient rim portion of the cup momentarily bulging into the inter-tongue spaces. The second or following cup, however, is retained by the tongues of the upper throat disk, as in FIG. 6. The follower weight resists upward displacement of the stacked cups, particularly when the lowermost cup is withdrawn by the grippingtype holder H which is pushed upwardly into engagement with this cup.

The modified form of dispenser 170 illustrated in FIGS. 14 to 17 is arranged for upfeed dispensing of conical paper cups 122 and is adapted for mounting on a counter or table top 55, as in FIG. 8. The dispenser includes a casing assembly comprising coaxial outer and inner tubular casing members 171 and 171' which extend vertically through an opening 56 in the counter and are attached at their upper ends to a dispensing head assembly 126. The dispensing head assembly includes a pair of relatively rotatable annular end fittings or adapters 130 and 130' of molded material, such as polyethylene, and further includes a cap ring 31 having a detachable screw threaded connection with the end fitting 130. The end fitting 130 includes a sleeve portion 134 snugly fitting on the outer casing member and rigidly secured thereto by rivets 135, the upper end of the sleeve portion having an internal annular shoulder 136 against which abuts the upper edge of this casing member. The end fitting 130 further includes an outwardly projecting flat ring portion 137 integrally joining the upper end of the sleeve portion 134 and provided with a peripheral flange 157 of tapered cross-section having a thin outer edge 158 adapted to be flexed tightly against the container top to aiford a moisture seal. As in FIG. 8, the outer casing 171 is fixed in position by a surrounding split clamping ring 59 engaging the underside of the counter and clamped about the casing by one or more screws 60. The lower end of the outer casing is provided with a bottom cover or closure 61, as

in FIG. 8.

The inner tubular casing member 171' is slightly smaller in diameter than the outer casing member and is rotatable therein about its vertical axis through a small angle as hereinafter described. The upper end of the inner casing member has rigidly secured thereto the end fitting 130 which includes a sleeve portion 134' fitting 6 within the inner casing member and secured thereto as by rivets The end fitting 130' further includes a flat ring portion 137 which slidably bears on the upper face of the flange 137 of the companion end fitting 130 and is connected thereto by peripherally spaced projections 167 which slidably fit in arcuate dovetail slots 168 formed in the flange 137. Integrally formed on the outer edge portion of the flat ring portion 137' is an upstanding cylindrical ring portion 38 which is provided with exterior interrupted screw threads 40 corresponding to the screw threads 40 of FIG. 4 and engageable with internal screw threads 45 formed on the cap ring 31. Peripherally spaced radial bracing flanges 139 integrally connect the inner side of the cylindrical ring portion 38 with the flat ring portion 137.

A pair of centrally open

resilient throat disks

132 and 133, like those of FIG. 13, and an associated annular gasket ring 46 are detachably clamped to the end fitting 130' by the screw-threaded cap ring 31 which is like that of FIGS. 2 and 8. The cap ring is detachable to permit downward loading of a stack of cups into the inner casing member, and the throat disks and gasket ring remain on the cap ring when it is detached.

A follower plate or disk 173 is movable axially in the inner casing member 171 and is urged upwardly by a coiled conical spring 64 attached to this plate and to the bottom closure by respective riveted

clips

65 and 66. The upward travel of the follower plate is limited by stop embossments 172 formed on the inner casing member. The spring-urged follower plate 173 has rigidly attached thereto, as by riveted angle brackets 174 an upstanding bar 175 which enters the lowermost one of the inverted stacked conical cups 122 and engages the inner walls of this cup, thus urging the stacked cups upwardly.

To resist or limit downward or retrograde movement of the stacked cups during a dispensing operation the follower plate 173 is provided with a pair of diametrically opposite pawls 176 in the form of thin resilient metal plates secured at their inner ends, as by rivets 177, to the underside of the follower plate, the outer ends of these pawls being engageable with diametrically opposite vertical rows of ratchet teeth or shoulders 17 8 struck up from the inner casing member 171'. The pawls 176 will yield past the teeth to permit upward spring-urged displacement of the follower plate 173 as the cups are successively withdrawn from the dispenser.

When the dispenser of FIG. 15 is to be loaded with a stack of cups, the cap ring 31 is rotated in unscrewing direction to remove this ring. During the first part of this rotation the inner casing member 171' rotates with the cap ring and end fitting 130' through a small angle to bring the ratchet teeth 178 of this casing member out of register with the pawls 176 on the follower plate, so as to permit downward displacement of the plate against the pressure of the cup-elevating spring 64. This rotation is limited by the abutment of the connector projections 167 with ends of the arcuate dovetail slots 168. Further rotation of the cap ring in the same direction will release this ring from the end fitting 130 and permit a limited upward travel of the follower plate into abutment with the stop embossments 172. A stack of the inverted conical cups 122 is then pushed downwardly into the inner casing member, the inner walls of the lowermost cup engaging the upstanding follower bar 175 and depressing the follower plate 173. The cap ring, carrying the throat disks, is then screwed back onto the end fitting 130', and during some part of this angular displacement of the cap ring the inner casing member is rotated thereby to bring the pawls 176 back into alignment with the rows of ratchet teeth 178. The dispenser is then in condition for dispensing of cups from the device.

FIG. 15 shows the position assumed by the

tongued throat disks

132 and 133 when a stack of the smallestsized conical cups 122a is housed in the casing, these cups being shown in full lines. In the case of somewhat larger conical cups 1220, one of which is indicated in broken lines, the resilient tongues of the throat disks will assume a normal outwardly deflected position, similar to that shown by broken lines in FIG. 11.

The foremost or uppermost cup is withdrawn from the dispenser of FIG. 15 either by direct manual grasping of the cup or by the use of the cup-gripping holder H shown in FIG. 14, the ratchet-controlled follower plate 173 preventing or limiting retrograde movement of the stacked cups during this dispensing operation, and the resilient tongues of the throat disks flexing outwardly to pass the foremost cup and to separate this cup from the following cup.

In each form of cup dispenser, the provision of two or more cooperating throat disks simultaneously engaging the foremost cup insures proper support or retention of a relatively long column or stack of cups, while permitting the use of relatively thin disks with cup-engaging tongues which are quite resilient and deflectable through a large angle without acquiring a permanent set, so that the dispenser is able to accommodate cups having a wide range of rim diameters. By way of example, the plastic throat disks may have a thickness of the order of 0.015 inch. While the resilient throat disks are desirably formed of plastic, in some instances they may be made of sheet metal.
