Abstract

Abstract of the Disclosure A package includes two or more individual cup dispensing units, each unit comprising a carton holding a stack of nested tapered cups. Each carton of a dispensing unit is of paperboard having a generally circular opening in a top wall through which the tapered cups protrude, and which opening is surrounded by a series of short radial knife cuts defining a series of yieldable tabs on the wall which permit the topmost protruding cup to be pulled through the opening, but which function to restrain the cups immediately below. The botom wall of the carton is formed with a generally circular opening, either fully cut-out or defined by a series of radial cuts, which permits the protruding tapered cups of a similar, adjacent carton to extend through the bottom opening into the carton to form a compact, multiple dispensing unit package which is shrink wrapped for shipping and display.

1 3, 794 _CKGROU~D OF THE INVE~TION

This invention relates to packaging, and more particularly to package structure for stacXs of nested cup6 that serves also as apparatus for dispensing the cupsO
Cup dispensers are well known in the art and generally require some form of permanent mounting on a wall or other suitable structure~ It is not always practicable to mount a dispenser of this type in every desired location, and they frequently are mounted in a single location not convenient to all users.
It is an objective of this invention to provide an improved package structure for nested paper cups that is suited as dispensing apparatus useful in a variety of locations, It is a further objective of the invention to prov.ide an improved package structure for nested cups that iq separable into self contained units each serving as a dispensing apparatus, and which units are adapted for use without need for permanent mounting structure.

SUMMARY OF THE INVENTIo~

In achievement of the foregoing as well as other objectives, the invention contemplates an improved package structure including at least a pair of separable units~
each unit adapted to sarve as a cup dispensing apparatus and comprising: a container having substantially planar, parallel, mutually spaced first and second walls; each said wall including a generally circular opening, the opening in said first wall axially aligned with the L2~3~S'~L

opening in said second wall; said container being adapted to hold a stack of nested cups each having a tapered side wall, a circular bottom wall, and a circular open top, said bottom wall being smaller than either of said openings, and said open end being greater than at least said opening in said second wall, whereby said stack protrudes through said opening in said second wall at its one end and rests on said second wall in the region of the opening therein, the recited protruding stack of one of ~aid containers extending through said opening in said second wall of the other of said containers so that said la~t recited second wall is disposed in engagement with the first wall of the recited one container, said cups being dispensible by grasping a protruding cup and removing it through said irst opening of a container, either in the recited assembled mode of said units or in the ~eparated mode thereof.
The manner in which the foregoing as well as the other objectives of the invention may best be achieved will be more fully understood from a consideration of the following description, taken in light of the accompanying drawing.

-~` lZ~9S~:~

Figure 5 is an elevational showin~ of the package in Figure 2, with a portion sectioned generally along the line 5-5: and Figures 6 and 7 are perspective views, from above and below, respectively, of a modified embodiment of the invention.

Description of the Preferred Embodiment With mor~ detailed reference to the drawing, there is seen in Fig. l a package lO of two pairs of ~ta~ked unit~ 11, each identical to the other and comprising containers or cartons of paperboard serving as dispensing apparatus. Referring also to Figs. 2 and 3, each carton ll is of generally rectangular configuration, including planar, parallel, mutually spaced first and second walls 12 and 13, respectively, joined by planar ~ide walls 14, 15, 16 and 17.
As is seen also in Fig. 3, irst or upper wall 12 inaludes a generally circular opening 18, and, as is seen in Fi.g. 4, second or lower wall 13 includes a generally circular opening l9 axially aligned with opening 18.
Opening l9 pxeferably is smaller or of lesser diameter than opening 18, and along its periphery there are provided radially inwardly projecting tabs 20 defined by radial knife cuts 21 in lower wall 13. Tabs 20 are connected to wall 13, along the periphery of opening 19, and include perforations 22 extending transversely of the bases of the tabs so that the perforations are substantially aligned with the periphery of opening l9~
The upper opening 18 preferably is larger or of greater diameter than opening 19, and is substantially defined by tabs 23 which, in turn, are defined by relatively short xadial knife cuts 24.

-` ~ZQ~

As is se~n to advantage in Fig. 5, an inverted stack of tapered cups 25 is disposed in each carton 11, wherein the tapered side wall and bottom wall of the end cup of a cup stack protrudes through the larger opening 18, and the open top of the other end of the same cup stack rests on the lower wall 13, in the region of perorations 22. Tabs 20 conveniently serve as a dust cover for the lower walls of a lowermost carton 11 of a package. Tabs 23 defining the upper opening 18 are sufficiently flexible and resilient, as is the nature of the paperboard of the carton, to accommodate one-at-a-time removal of protruding cups through opening 18.
As is further seen to advantage in Fig. 5, the pair of stacked cartons 11 are so positioned that the protruding end cup 25 of a cup stack in one carton 11, i.e lower carton, ~xtends through the s~aller opening 19 of the other carton 11, i.e. upper carton, flexing the radial tabs 20 about perforations 22 and being received in the open top of the ~ottom or lowermost cup of the inverted ~tack in the upper carton 11. Further to the paired cartons 11, the lower wall 13 of the uppar carton is disposed in engagement with the upper wall 12 of.the lower carton, whereby the upper carton is supported on the lower carton. To separate a pair of stacked cartons, one need only lift an upper carton to a position as shown in Fig. 5 Assembly of the side-by~side pairs of cartons 11 as a package 10 is maintained by a sheet of flexible material such as a clear plastic film overwrap 27 (Fig. 1) held in the illu~trated rectangular form over the protruding cup stacks ~y a flat rectangular sheet 2~ of stiff plastic material in an inverted U-shape configuration, wherein tha flat loop portion rests atop the inverted cup stacks and the leg portions are generally coplanar with the sides of the assembled cartons as shown.

~2~95~

While two pairs of cartons 11 are illustrated as making up the package 10, it will be appreciated that several pairs may be arranged side by side, in a single line, or in a square array, either being overwrapped with a clear plastic sheet or film as shown, and having a form al~o as shown to present a flat upper package surface facilitating stacking of several packages. Alternatively where stacking of the packages is not contemplated, a~sembly of a package may be achieved using conventional shrink-wrapped film without the form 27.
The invention also contemplates an al~ernative embodiment, as is seen in Figs. 6 and 7, wherein two or more cartons 111 may be arranged atop one another in a package 110, and assembly may be maintained by clear wrapping film 126.
In any of the described combinations, the inventive structure achieves both practical and aesthetic qualities desired of a cup dispenser, affording an attractive, compact package capable of ready disassembly by the user into equally attractive, easy to use diqpenRing unit~.
While paperboard i9 the preerred material of the caxton, it will be apparent from t~le foregoing that other materials affording adequate flexibility and resilience for 1exure of the tabs, such as polyethylene or like plastic, ox laminates including paperboard, plastic, or metal foil, will be suitable for use in achieving objectives and advantages of the invention.
It will be appreciated that the foregoing as well as other altarnative embodiments may be resorted to without departing from the scope of the claims.
