The present invention relates to dispensing containers and more particularly relates to containers for dispensing yieldable articles such as paper cups, assembled in nested or telescoping relation.

One object of the present invention is to provide a collapsible dispensing container having parts thereon adapted, in the collapsed condition of the container, to lie within the contour of the container walls, assuring compactness of the collapsed container, such parts being adapted readily to be moved to a position inwhich the parts can be extended inwardly of the container when it 'is brought to an expanded condition so that the inwardly extending parts provide retention devices serving to retain a column of nested articles such as paper cups but permitting them to be removed one at a time from the container by grasping the lowermost article by the hand and withdrawing it past the retention devices.

A further object of the invention is to improve and simplify containers of the class described and to provide a form of container that can be packed with articles without special machinery as well as without the necessity of employing skilled operatives. At the same time a form of container is provided that affords ample protection to its contents during storage and shipment and can be adapted for dispensing of its contents with only a very simple operation upon the container at the time it is desired to convert it into its dispensing condition.

To these and other ends the present invention.

resides in certain combinations and arrangement of parts described below, the novel features of which are defined in the claims hereto appended.

Fig. 7 is a section taken on line 1-1 of Fig. 6 looking in the direction of the arrows.

The present invention, as herein disclosed, comprises a collapsible, tubular container. having top and bottom closures and means for dispensing articles one at a time from the container, such means being normally inoperative until such time that it is desired to employ the container as a dispensing container, whereupon the container is converted to dispensing form by the simple oper: ation of pushing inwardly certain parts thereof.

Referring more particularly to the drawings, the container, as illustrated in Fig. 1, comprises a tube In of flexible sheet material such as foldin paperboard. The container is preferably formed .fiaps l1 and I 9 being adapted to interlock in overlying relationship with respect to the flaps l G and [8, to close the top of the carton. The flaps "a and i911 likewise are adapted to interlock in overlying relationship with respect to the flaps Ilia and No, to close the bottom of the carton.

For the purpose of withdrawing cups from the carton, the bottom end of the carton is opened and the bottom closure flaps Ilia, I la, l8a and Na are removed from their respective side wall panels. To facilitate the removal of said flaps, score line 20 separating the flaps from their body panels, is preferably formed in the nature of a line of severance whereby the flaps may be easily and quickly removed while at the same time, after their removal, a smooth, neatly appearing edge is presented at the bottom of the open carton as indicated at 2] in Fig. 2.

The carton formed from the type of blank shown in Fig. 4 of the drawings is particularly suitable for dispensing conical shaped paper cups having a top edge formed without any bead or extended lip.

Retention elements are formed in the side walls near the bottom of the carton to hold the cups therein until they are desired for use. The retention elements of the present invention comprise pairs of integrally connected triangular segments, indicated at 22, 23 in Fig. 4, the triangular segment 22 being defined by the hinge line 24, the comer forming score line 25 and a free edge 26, and. the triangular segment 23 being defined by the hinge line 21, the score line and free edge 28. The hinge lines 24 and 27 diverging from the corner forming score line 25 extend upwardly and inwardly of adjacent side wall panels. The corner forming score 25 in the present blank is disposed in alignment with the score line which separates adjacent side wall panels and which, when the carton is set up, forms a corner of the carton. The free edges 25 and 28 of the triangular segments are formed by cuts extending from the outer ends of the hinge lines 24 and 21 and meeting at the upper end of the score line 25.

The triangular segments thus provided are adapted to be swung inwardly of the carton when adjacent side wall panels aredisposed in an angular relationship with each other. to thereby provide cup retaining elements.

In the present instance the retention elements extend inwardly of the carton sufficiently to support a column of nested paper cups'as shown in Fig. 2 and Fig. 3. In the case where the cups nest closely and form a relatively compact group, the retention elements are required to support a considerableweight. Furthermore, due to the tapered shape of the cups, as illustrated, the downward pressure exerted by the column of cups held in the carton has a lateral component tending to press the retention elements outwardly. For that reason the hinge lines 24 and 21 are preferably formed in angular relationship with the corner forming score line 25 such that when the retention elements are swung inwardly of the carton, the edge of the element formed along score line-25 will project inwardly below a line normal to the contacted surfaces of the cups contained in the carton as illustrated in Fig. 2'.

To minimize the amount of material struck from the side wall panels to form the retention elements shown in Fig. 2, it is desirable to have the free edges 26 and 218 of the triangular segments extend downwardly from the upper end of the corner forming line 25 as shown in Fig. 4. The angles defined by the edges 26 and 28 with the score line 25 are also preferably formed to provide supporting contact between the cups in the carton and substantially the entire free edges of the triangular segments. It is apparent that the triangular segments 22, 23 provide duplicate engaging edges 26, 28, either one of which can function to give a column of cups adequate support so that even if the carton should be subject to a slight distortion there will be at least one segmental edge of each pair engageable with the side of a contained cup, in which case the other segment in the pair functions principally as a holdingor limiting means for the engaging segment thus keeping it in proper engaging relationship with the cup.

As shown in Figs. 2 and 3, the distance between the cup supporting portions of opposite retention elements is less than the diameter of the top portion of the contained cups, thereby, as above indicated, providing means to retain the paper cups in the carton. It is to be noted, however, that due to the fact that the present cups for which this carton is designed are made of resilient material, it is possible to withdraw the lowermost cup from the end of the carton by grasping the bottom of 'the cup and pulling it with sufficient force to cause a distortion of its upper portion, as shown in Fig. 3. Due to the fact that the cup immediately above the one being withdrawn is, because of the nesting arrangements of the cups, interiqrly supported in such a manner as to prevent distortion thereof, said cup is retained in the carton until it, in turn, is grasped and manually withdrawn.

When it is desired to pack paper cups of the type having a beaded upper edge projecting outwardly beyond the side wall of the cup, such as a frusto-conical type of cup, the retention elements are pr r r ged so that two adjacent elements are located somewhat above the other pair of adjacent elements. Such an arrangement is embodied in a modified form of the present invention. A blank'3fl of a carton made in accordance with the modified form is shown in Fig. 5.

The blank 30 is suitably cut and scored to provide side wall panels 3|, 32, 33 and 34 and an attaching flap 35 on wall 34 by means of which the walls 3| and 34 may be joined together as by means of adhesive. The top and bottom end closures may be formed by flaps 36, 31., 33, 39, 36a, 31a, 38a and 39a, the flaps 3'! and 39 being adapted to interlock in overlying relationship with respect to flaps 36 and 38, to close the top of the carton, and the flaps 31a and 39a. likewise being adapted to interlock in overlying relationship with respect to the flaps 36a and 38a, to close the bottom of the carton. The score line 40, defining the bottom closure flaps, is preferably formed in the nature of a line of severance to facilitate the removal of said flaps from the carton prior to the dispensing of the cups contained therein.

The pair of adjacent retention elements 4|, 4| are each formed of the triangular segments 42, 43 and preferably substantially identical to the retention elements formed by the triangular segments 22 and 23.

The retention elements 4|, 4| are arranged somewhat nearer the bottom of the carton than the other two retention elements indicated at 50, 5|, for purposes later to be described. The element 5" comprises triangular segments 52, 53 and the element 5| comprises triangular segments 54, 55.

For purpose of forming the blank shown in Fig. 5 into tubular shape, the attaching flap 35 is ad hesively secured to the side wall panel 3|, in which case the triangular segment 56 of the attaching flap 35 is secured to the similar triangular segment 55 of panel 3|. Together, the se ments 56 and 55 constitute a segment similar to segment 53, and with triangle segment 54 comprise the retention element 5| shown in Fi 7. As shown in Fig. 5, the triangular segment of the attaching flap 35 is defined by the comerforming score line 64, a horizontal cut, and a slot disposed angularly with respect to the score line 64. Said slot is provided for the purpose of facilitating inward deflection of the retention element 5|, it being apparent that triangular segment 55 will be adapted to swing withits adhesively attached triangular segment 55, about the hinge line 62 when the blank has been formed into tubular shape. For the same purpose a similar slot is provided in the attaching flap |5 of the type of blank shown in Fig. 4 to define one edge of the triangular segment formed in said flap l5.

As the frusto-conicai type of cups, for which the modified form of carton is designed, and which are indicated by dotted lines in Fig. 6, are formed with beaded rims, they ofier a greater resistance to distortion than in the case of the conical shaped cup having no reinforcement around its rim. Due to the fact that the frustoconical type of cup resists distortion, to cause a their rims.

separation of the lowermost cup 51 in the carton from the cup 58 immediately above it and nested therein, it has been found to be advantageous to cause the lowermost cup 51 upon withdrawal to move somewhat out of alignment with cup 58. To obtain this relative movement 'between cups 51 and 58, the retention elements 4|, 4| are spaced nearer the bottom of the carton than the retention elements 50 and 5|,

thereby as the cup 51 is grasped and withdrawn from the carton, said cup is forced sidewise when it engages the elements 50 and 5|, as shown in Fig. 6. By reason of the close nesting of the cups contained in the carton, sidewise movement of the cup 58 is somewhat resisted and thereby separation of said cups 5? and 58 is-facilitated.

When the lowermost cup assumes a position where it is engaged by eachof the retention elements 4|, 4|, 50 and 5|, there is suflicient sepa ration between the cups 5'! and 58 to permit the complete withdrawal of cup 51, while at the same time cup 58. is retained by the retention elements until it,. in turn, is manually withdrawn from the carton.

Due to the fact that the frusto-conical shaped cups are commonly provided with an outwardly extending peripheral projection such as a headlike rim to reinforce the cup, it has been found desirable to form the elements 50 and 5| such that they are more rigid than the'type of elements used in dispensing cartons adapted for conical shaped cups having no projections on It has also been found that, due to the projections on the frusto-conical type of cups, there is no substantial tendency for the elements 50 and 5| to be forced outwardly for the reason that the projecting portions tend to exert an effective downward force on said elements. Therefore to provide for the desired rigidity in the elements 5|] and 5|, the hinge-forming score lines indicated at 59, 60 and 6|, 62 are preferably disposed in an angular relation to the corner-forming score lines 63 and 64, respec- The bottom flaps are then torn off, along the weakened line 20 or weakened line 40, as previously described. The container is then ready to be suspended on a convenient nail or hook after which it is ready for use as a cup-dispensing container.

From the foregoing it is clear that, due to the construction and. arrangement of the parts of the retention elements, when the retention elements are in an inwardly directed position, as illustrated in Figs. 1, 2 and 3, the column of cups shown in dotted lines in Fig. 2 will be supported by the retention elements due to the manner in which these elements bear against the sides of tively, such that when the retention elements .1 and 4. A similar slit or opening 1| is provided in wall 34, see Fig. 5.

The use and operation of the container of the I present invention will now be described. The containers are formed into open end collapsible tubes with the retention element lying within the plane of the container walls, as illustrated at the right hand corner of the container as shown in Fig. 1. They are shipped to the packer in flat condition and the packer will fill the container with the desired number of cups in nested formation as suggested in Figs. 2 and 6, where small groups of nested cups are illustrated. The 010- sure flaps of the container are then secured in closed position and the container is then ready for shipment to the user.

- A convenient way of conditioning the filled container for dispensing the cups is to first press inwardly upon the retention elements so that they will assume the position as illustrated in Figs. 2 and 6, depending upon the form employed.

, somewhat inwardly due to connection between the lowermost cup. The weight of the column of cups is thus supported by the retention elements. A relatively heavy weight of cups in column formation can be supported by the retention elements as there is no likelihood that any of the retention elements will be forced to its original position where its parts will lie within the plane of the container walls. This is due to the fact that the retention elements are so formed that the hinge line between the two. segments, as shown at 25, Figs. 3 and 4, will assume a position in respect to the cups which is less than a right angle. In other words, the hinge line 25 is so disposed as to engage the side of the cup at an angle which is other than normal or at right angles to the side of the cup, whereby the downward force exerted upon the retention elements by the cups will produce a lateral force which is a component of the downward force tending to swing the retention elements still further away from their original position within the plane of the container walls. The eiiect of this tendencypf the retention elements to swing down instead'of up, as illustrated in Fig. 2, is that the portions at the hinge line 25 of the retention element swing about the point at which this line joins the fold line between the adjacent side walls and, as the comers of the container are relatively rigid, any excessive pressure imposed upon the retention elements to swing them down, as illustrated in Fig. 2, will produce an inward deflection of the walls to which the retention elements are connected at portions of such walls remote from the fold lines therebetween. Thus any'excess pressure imposed upon all of the retention elements will cause inward deflection of portions of the walls intermediate their edges. This tendency toward inward deflection of the walls will produce a gripping effect upon the column of cups so that, within the limits of the strength of the material employed, the gripping force exerted upon the column of cups will be in more or less direct proportion to the weight of the column.

In the form of the retention elements illustrated in Figs. 5, 6 and 7 it is to be observed that the upper retention element 5|] offers more resistance to the column of cups than is the case with the retention element 4|, this being due to the fact that when the projecting portions of the cups come into contact with the edges of the element 50, there is a tendency to produce an inward swinging movement in the direction of the line which is normal to the line of the corner of the container. This tendency causes the passageway between the retention elements to become more constricted asthe elements approach the horizontal and at the same time the intermediate portions of the walls are drawn the segments of the retention elements and the tion that is the case with the downwardly projected retention elements.

When the form of retention element, as illussegments being each hinged to a line within trated at 50 in Fig. 6, is employed there is no tendency for the retention elements to be forced into their original position in the plane of the container walls in the angle illustrated, particularly with cups having projecting lip portions, for the reason that before the pressure exerted by the side of the cup against the retention elements becomes great EIlOlEh to produce any appreciable outward component of force upon the retention element, the projecting li of the cup will engage the retention element and tend to draw its edges in the direction of movement of the cup being withdrawn.

The triangular segments are each preferably so shaped as to provide for contact with the side portions of the cups, thus even if one of a pair of segments does not contact the cup side the other segment will do so. In such a case the segment not contacting a cup side nevertheless performs the necessary function of holding the companion segment in cup-engaging position.

In both forms of the carton disclosed herein and made in accordance with the present invention the retention elements, being formed of hingedly connected triangular segments, provide supporting elements that may be formed of relatively light weight paperboard while at the same time being more sturdy than other types of retaining elements heretofore used.

While the present description sets forth certain preferred embodiments of the invention, numerous changes may be made in the construction without departing from the spirit of the in vention and it is, therefore, desired that the present embodiments be considered in all respects as illustrative and not restricted, reference being had to the appended claims rather than to the foregoing description to indicate the scope of the invention.
