Abstract

Emballage distributeur pour piles de gobelets coniques emboîtés qui sert en même temps de conteneur de transport et de dispositif de distribution de gobelets. Le problème relatif à des distributeurs de gobelets est qu'il n'est pas toujours possible de monter le distributeur à l'emplacement voulu. Le système ci-décrit permet de réaliser une pluralité de conteneurs contenant les gobelets et empilables les uns sur les autres de manière à pouvoir être utilisés à des emplacements et des positions différents. L'emballage distributeur (11) contient une pile de gobelets jetables coniques emboîtés (25) et permet de les distribuer individuellement. L'emballage distributeur (11) possède une ouverture généralement circulaire (18, 118) dans la paroi supérieure (12, 112) au travers de laquelle les fonds des gobelets coniques font saillie et sont entourés d'une série de languettes ou segments flexibles (23, 119) autour de la périphérie qui permettent de faire sortir un gobelet en le tirant au travers de l'ouverture, tout en bloquant le gobelet immédiatement en dessous. Des fentes ou des coupures au couteau (26, 122) dans la paroi supérieure (12, 112) de l'emballage distributeur (11) s'étendent de l'ouverture (18, 118) dans la paroi supérieure (12, 112) jusqu'à chacune des parois latérales (14, 15, 16, 17) au point médian de chaque paroi latérale pour permettre l'empilage d'une série de gobelets (25) au travers de l'ouverture supérieure (18, 118) de l'emballage distributeur (11) sans déchirer la paroi supérieure (12, 112). Une ouverture (19) peut être aménagée dans la paroi de fond de chaque emballage avec des fentes radiales (21) s'étendant vers l'extérieur à une distance suffisante pour permettre l'empilage des emballages individuels (11) en un paquet (10) compact et composé d'unités multiples pour le transport et l'étalage.Dispensing packaging for stacked conical cup stacks which serves simultaneously as a transport container and cup dispensing device. The problem with cup dispensers is that it is not always possible to mount the dispenser in the desired location. The system described allows for a plurality of containers containing the cups and stackable on each other so that they can be used at different locations and positions. The dispenser package (11) contains a stack of nested conical disposable cups (25) and allows them to be dispensed individually. The dispenser package (11) has a generally circular opening (18, 118) in the upper wall (12, 112) through which the bottoms of the conical cups protrude and are surrounded by a series of flexible tongues or segments ( 23, 119) around the periphery which allow a cup to come out by pulling it through the opening, while blocking the cup immediately below. Slots or knife cuts (26, 122) in the top wall (12, 112) of the dispenser package (11) extend from the opening (18, 118) in the top wall (12, 112) to each of the side walls (14, 15, 16, 17) at the midpoint of each side wall to allow stacking of a series of cups (25) through the upper opening (18, 118) of the dispenser packaging (11) without tearing the upper wall (12, 112). An opening (19) can be provided in the bottom wall of each package with radial slots (21) extending outward at a distance sufficient to allow stacking of the individual packages (11) into a package (10 ) compact and composed of multiple units for transport and display.

Description

DISPENSER PACKAGE

This invention relates to a dispenser package for stacks of nested tapered cups that serve as a shipping container and also as apparatus for dispensing the cups.

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.

This invention provides an improved package structure for nested paper cups that is suited as dispensing apparatus useful in a variety of locations.

This invention comprises an improved package structure comprising a container having substantially planar, par¬ allel, mutually spaced first and second walls; each said wall including a generally circular opening, the opening in said first wall axially aligned with the 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

OMPI IPO 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 said containers extending through said opening in said second wall of the other of said containers so that said last 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 first opening of a container, either in the recited assembled mode of said units or in the separated mode thereof.

Fig. 7 is a bottom view of a container illustrating a modification of the structure illustrated in Fig. 4; Fig. 8 is a plan view of a container illustrating another embodiment of the container.

With reference to the figures. Fig. 1 illustrates a package 10 of two pairs of stacked container units 11 and 11' , each identical to the other and comprising containers or cartons of paperboard capable of serving as dispensing apparatus. Referring also to Figs. 2 and 3, each carton 11 and 11' is of generally rectangular configuration, in- eluding planar, parallel, mutually spaced first and second walls 12 and 13, respectively, joined by planar side walls 14, 15, 16 and 17.

As is seen in Fig. 3, first or upper wall 12 includes a generally circular opening 18, and, as is seen in Fig. 4, second or lower wall 13 includes a generally circular opening 19 axially alligned with opening 18. Opening 19 preferably 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 perfora¬ tions 22 extending transversely of the bases of the tabs and outlining a polygon with the perforations substan- tially aligned with the periphery of opening 19. 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 radial knife cuts 24.

Perforations 22 are arranged so that they do not intersect the slits formed by radial knife cuts 21, i.e. the per¬ forations 22 do not join 21. Tabs 20 may be pushed inward to form an opening in the bottom 14 of the dispenser package, preferably of somewhat smaller diameter than opening 18 in the top of the package, the tabs 26 bending along lines defined by perforations 22.

As is seen to advantage in Fig. 5, an inverted stack of tapered cups 25 is disposed in each carton 11 and 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 cup of the same cup stack rests on the lower wall 13, in the region of perforations 22. Tabs 20 conveniently serve as a dust cover for the lower walls of a lowermost carton 11 of a package. Tabs

23 defined 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 protrud- ing cups through opening 18.

In the embodiment illustrated in Fig. 6, the top wall 12 of each dispenser package 11 and 11' is provided with slits or knife cuts 26 extending from the circular opening 18 to each of the sidewalls 14, 15, 16, and 17, at a point on the circular opening 18 adjacent each sidewall. The slits or knife cuts 26 are preferably positioned to extend from the center of the top of each side wall to the circular opening 18, the cuts intersecting the circular opening at a point on its periphery nearest the adjacent sidewall. It has been found that provision of the slits or knife cuts 26 permit a stack of cups 25 to be loaded into the package 11 through the top opening 18 without tearing the top wall 12 and without disabling the tabs 23.

In another embodiment, illustrated in Fig. 7, tabs 20 formed by knife cuts 21 on the bottom wall 13 of the dispenser package are joined at their inner ends by webs 20' holding the tabs 20 in place until the webs are ruptured by insertion of the small end of a protruding

OMPI ^"stack 25 of cups in one package into the open end of a stack

25 of cups in another package thereby tearing the webs 20' " and pushing tabs 20 inward. It will be evident that any number of dispenser containers may be stacked in this

5 manner to form a compact package.

An alternate preferred embodiment of opening 18 in the upper wall of the container is illustrated in Fig. 8. In this embodiment, the top wall 112 of the dispenser package

10 is provided with a generally circular or generally octa¬ gonal opening 118. In the preferred embodiment illus¬ trated in Fig. 8, the opening 118 is made up of four arcuate jaws 119, the arcuate segments each subtending an angle of 40° to 45° and each interconnected to four

15 straight sided segments 120 by curved fillets 121 having a small radius relative to the radius of the arcuate portion of jaws 119. The upper opening 118 as defined by the straight sided segments 120 and the circular segments of arcuate jaws 119 are smaller than the diameter of the

20 top curl or rim of a cup. The purpose of the arcuate jaws 119 will become apparent from the following description of their function.

In use, an inverted stack of tapered cups 25 is disposed 25 in dispenser package 11, as illustrated in ig. 5 such that the tapered side wall and bottom wall of the end cup of a cup stack protrudes through opening 118, and the open top of the other end cup of the cup stack rests on the lower wall 13. Jaws 119 defining the smaller diameter portion 30 of opening 118 are sufficiently flexible and resilient to permit the withdrawal of one cup through opening 118 while retaining the remainder of the stack.

The top wall 112 of this embodiment of the dispenser 35 package is provided with slits or knife cuts 122 extending

OMPI from the midpoint of each of straight segments 120 de¬ fining opening 118 in the top wall 112 of the dispenser package to each of the sidewalls 14, 15, 16, and 17, at the midpoint of each sidewall. The knife cuts are perferably positioned to extend from the center of the top of each sidewall to the center of each straight segment 120 as il¬ lustrated in Fig. 8. Knife cuts 122 permit a stack of cups 25 to be loaded into the package through the top opening 118 without tearing the top wall 112 of the package and without damage to arcuate dispensing jaws 119. The straight segments 120 are preferably parallel to the side walls and the arcuate jaws 119 are preferably opposite the corners of the top wall.

In this embodiment of the invention, four diagonal slits or knife cuts 124 in the top wall 112 of the package may be provided to intersect the opening 118 at the midpoint of the arcuate dispensing jaws 119. As a cup is dispensed, at times several cups may cling to one another whereupon the diagonal knife cuts 124 cause a slight division of dispensing jaws 119 on each side of slits 124 allowing the segments of the dispensing jaw to snap over the top rim or curl of the first cup onto the rim of the trailing cup thereby separating the cups and allowing a single cup to be dispensed. The combination of curved or arcute jaws 119 and interconnecting straight sided segments 120 and ra¬ dial slits 124 move with a slight independence of one another to provide an improved cup dispensing package. The straight sided segments 120 contact only a very small area of the rim of a cup on either side of knife cuts 122. This arrangement serves to reduce resistance to with¬ drawal of a cup from the package. The combination of arcuate jaws 119, straight segments 120 and radial slits 122 and 124 cooperate to allow slight separations of the knife cuts with just enough movement for dispensing a

O PI single cup while retaining the remainder of the stack in the package.

As is further seen to advantage in Fig. 5, the pair of i 5 stacked cartons 11 are so positioned that the protruding end cup 25 of a cup stack in one carton 11, i.e. lower carton, extends through the smaller opening 19 of the other carton 11, i.e. upper carton, flexing the radial tabs 20 about perforations 22 and being received in the

10 open top of the bottom or lowermost cup of the inverted stack in the upper carton 11. Further to the paired cartons 11, the lower wall 13 of the upper carton is disposed in engagement with the upper wall 12 of the lower carton, whereby the upper carton is supported on the lower

15 carton. To separate a pair of stacked cartons, one need only lift an upper carton to a postion 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

20 such as a clear plastic film overwrap 27 (Fig. 1) held in the illustrated rectangular form over the protruding cup stacks by a flat rectangular sheet 26 of stiff plastic material in an inverted U-shape configuration, wherein the flat loop portion rests atop the inverted cup stacks

25 and the leg portions are generally coplanar with the sides of the assembled cartons as shown.

While two pairs of cartons 11 are illustrated as making up

"V the package 10, it will be appreciated that several pairs

30 may be arranged side by side, in a single line, or in a square array, either being overwrapped with a clear plas¬ tic sheet or film as shown, and having a form also as shown to present a flat upper package surface facilitating stacking of several packages. Alternatively, where

35 stacking of the packages is not contemplated, assembly of a package may be achieved using conventional shrink- wrapped film without the form 27. Alternatively, a plurality of containers may be arranged atop one another in a package, and assembly may be maintained by clear wrapping film.

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 dispensing units.

While paperboard is the preferred material of the carton, it will be apparent from the foregoing that other mater- ials affording adequate flexibility and resilience for flexure of the tabs, such as polyethylene or like plastic, or 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 alternative embodiments may be resorted to without de¬ parting from the scope of the claims.
