Abstract:
A dispenser for cup holders for flexible cup liners, in which the cup holders are stacked one on top of the other in a tube having a slot in the side thereof for receiving the handles of the stacked cup holders and the slot having an inlet slot portion for receiving the handles, an offset slot portion in which the handle of the lowest cup can rotate, and a discharge slot portion for discharging the lowest cup from the bottom opening of the tube after rotation of its handle.

Description:
BACKGROUND OF THE INVENTION 
     It is customary in industrial lunch rooms and offices where beverages are dispensed to utilize a rigid cup holder into which is inserted a thin flexible cup liner. The liner is truncated in shape with a flange at the bottom which snaps into position at the bottom of the holder. The cup holder can be made of a rigid plastic and will be retained at the dispensing location. The cup liners are usually stacked in cardboard containers and various devices are available for dispensing the liners one at a time from the stack prior to insetion into the cup holder. 
     It is also desirable to have a dispenser for the cup holders since they are more expensive than the liners and are reused at the serving location. A device for dispensing cup holders is disclosed in U.S. Pat. No. 3,788,487. In this device, the cup holders are placed in a cylindrical passage with the cup handles sticking out through an open slot in the side of the passage. However, it is necessary to lift each cup holder upwardly in the reverse direction from which it was inserted in the passage in order to remove it. Thus, when only several cup holders are at the bottom of the passage, it is necessary to move these cup holders a considerable distance in order to remove them. 
     SUMMARY OF THE INENTION 
     A cup holder for flexible cup liners is provided by the present invention which permits the cup holders to be stacked, one on top of the other, in a cylindrical tube. Instead of having to remove the cup holders from the tube upwardly in the reverse direction to which they were inserted, the cup holders are removed one at a time from the bottom of the tube. The tube contains a vertical slot extending from the top to the bottom of the tube and the cup holders are introduced into the top opening in the tube. The handles of the stacked cup holders enter the inlet portion of the slot at the top and extend through the slot as the handles move downwardly. The slot has an enlarged offset portion near the bottom of the tube which permits the handle of the lowest cup holder to engage a transverse support surface in order to support the holders stacked above it. When it is desired to remove the lowest cup holder from the dispenser, it is manually rotated by moving the handle in an opening formed by the offset portion until the handle lines up with a discharge slot. The height of the opening in the offset portion must be greater than the height of the cup holder handle to permit the handle to rotate and the width of the opening must be great enough to permit the handle to move from the inlet slot portion to the discharge inlet portion. 
     With such a structure, it is possible to remove the cup holders one after another from the bottom opening of the tube without having to lift the cup holders from the bottom of the tube up to the top of the tube. Also, the transverse edge of the slot offset portion can contain a slight upward rise which prevents accidental movement of the lowest handle from the inlet slot portion into position over the discharge slot portion.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT 
     Referring to FIGS. 1 and 2, the cup holder dispenser 10 consists of a cylindrical tube 11 preferably constructed of a side wall of a clear plastic material. The tube can be suppported upright on any flat surface by a top bracket 12 and bottom bracket 14. Top bracket 12 has curved arms 15 and 16 which partially surrounds the tube and are cemented or otherwise secured thereto. Also, a straight flange 17 projects upward and contains openings for fasteners 18 which can be any suitable fastener for connecting the bracket 12 to a wall surface or other surface. In a similar manner, bracket 14 has curved arms 20 and 21 which projects partially around the tube 11 and are cemeted or affixed thereto in any suitable manner. The bracket 14 has a downwardly extending flange 22 which contains openings for fasteners 23 so that the lower end of the tube 11 can be attached to a flat supporting surface. Each of the brackets 12 and 14 can have a lip or flange 24 which serves to position the brackets at the top and the bottom of tube 11. It is understood that any suitable mounting structure can be utilized to support the tube 11 in a vertical position in a location for dispensing cup holders 25 from the bottom opening 26 of the tube 11. 
     Each of the cup holders 25 are made of a rigid molded plastic material and are designed to be used with thin plastic liners which are disposable. Since the cup holders 25 are to be used over and over again, it is necessary that they be always available at the liquid dispensing location. 
     As illustrated in FIG. 3, each cup holder has a bottom opening 30 across which extends a bar 31 and fingers 32 are located slightly above the bar to engage a rim on the cup liner. Also, each cup holder has a ledge 34 which receives the base 35 of another cup so that the cup holders can be stacked one on top of the other. Each cup holder has a handle 36 extending from the top edge 37 of the holder and connected with an intermdiate tapered portion 38. 
     Tube 11 contains a slot 40 which extends the full length of the tube and is divided into an inlet slot portion 41, discharge slot portion 42, and an offset slot portion 43. As illustrated in FIG. 2, the handles 36, when in stacked condition, extend to one side of tube 11 through slot 40 and each handle is separated from handles of adjacent cup holders. 
     One side of the slot 40 has a vertical edge 40a extending vertically downwardly to a transverse offset edge 40b which terminates in a raised edge 40c. The raised edge then connects with a shorter vertical edge 40d. The other side of the slot 40 has a vertical edge 40e extending vertically downwardly to a transverse offset edge 40f which then connects with a shorter vertical edge 40g. The opposite edges 40a and 40e form the inlet slot portion 41; the edges 40a, 40b, 40c, 40f and 40g form the offset slot portion 43; and the opposite edges 40d and 40g form the discharge slot portion 42. The offset slot portion defines an opening 44 into which the handle 36 of the lowest cup holder can move during removal from the dispenser 10. The height of opening 44 is at least slightly greater than the height of the highest handle to be dispensed and the width of the opening is preferably slightly greater than twice the width of the widest handle to be dispensed. With such dimensions, the handle of the lowest cup holder can be gripped and rotated into opening 44 in order to become positioned over the discharge slot portion 42. The raised edge 40c is optional and when used, the stack of cup holders must be raised by force on the lowest handle before the handle can be roated as illustrated by FIG. 4. 
     As illustrated in FIG. 1, a plurality of cup holders 25 are loaded in the top opening 46 of the tube 11 with handles 36 projecting out from slot 40 and the handle of the lowest cup engages the transverse edge 40b to support the cup holders. The ledge 34 of each cup holder engages the bottom 35 of the cup holder directly above to maintain the holder in stacked position, with each of the handles projecting outwardly from slot 40. When it is desired to remove the bottom cup holder 25 from the dispenser 10, the handle 36 of the holder is gripped and all the cup holders are raised upwardly to permit the handle 36 to clear the raised surface 40c (see FIG. 4). The handle 36 of the lowest cup holder is then rotated into the space 44 and adjacent to the edge 40g so that the handle is directly above the discharged slot portion 42, formed by edges 40d and 40g. The rotated position of the cup holders is illustrated in FIG. 5. The handle then moves through the discharge slot portion and out of the dispenser as illustrated in FIG. 6. After the handle of the lowest holder is rotated, the stack of holders moves downwardly until the handle on the holder directly above engages the transverse surface 40b and this next cup is now in position for removal in the same manner from the dispenser when needed. 
     The purpose of the raised surface 40c is to prevent the handle 36 of the lowest cup holder from being accidently moved into the opening 44 and over the discharge slot portion 43 so that the cup holder would fall from the dispenser 10 when it is not needed. Normally, the weight of the cup holders in the stack above the lowest cup holder will hold the handle of the bottom holder is position, but the raised surface 40c makes accidental removal of the bottom holder more difficult. 
     It is understood that the width of the slot portions 41 and 42 will be sufficient to receive the widest cup handle that will be utilized for the dispenser 10. Also, the height of opening 44 between surfaces 40b and 40f is such that it will permit handle 36 of the lowest cup holder to be raised upwardly to clear the raised surface 40c. However, the height will not be great enough to permit rotation of the holder directly above the lowest holder and such rotation will be stopped by the lower portion of edge 40e. (see FIG. 5) Further, since the inlet and discharge slot portion are offset from one another, the width of opening 44 must be such as to provide a transverse support surface 40b adjacent discharge slot portion 42. Preferably, the transverse support surface 40b should be at least the width of the handle so that the width of the opening 44 between edges 40a and 40g would be at least twice the width of the handle. 
     It is apparent that the number and size of the holders which can be dispensed will depend upon the size of the dispenser and the size of the various slot portions. While the tube 11 is illustrated as round, the dispenser could be shaped to accommodate holders of various shapes and sizes. When tube 11 is made of plastic, the individual surfaces and edges can be smooth so they will not injure the hands when removing a cup holder. As holders are removed from the dispenser, the remaining holders will still form a stack and all holders will be removed through bottom opening 26. Except for the handles, the cup holders are continually covered by the tube 11 so that the dispenser maintains the cup holders in sanitary condition.
