PAPER CUP HOLDER Filed Feb. 7. 1952 3 Sheets-Sheet 3 United t es Patflt PAPER CUP HOLDER I-lerbertL. Bennett, Easton, Pa assignor to Dixie Cup Compan'y, Easton, Pa., a corporation of Delaware Application February 7, ;1952,'Ser'ia l No. 270,480 5 Claims. or. 65-61 flfhis invention relates to improvements in a paper cup holder, andmore particularly to a paper cup holder of up holders for paper cups have been developed, These holders are mostly used in soda fountains and similar locations where various types of hot and cold drinks are individually dispensed. The paperrcups are usually kept 'in stacked nested relationship on the back bar, frequently with the stack inverted, and the clerk or operator grasps a holder by .the bottom, presses it axially over the terminal fcupl'of the stack, and a gripping element in the holder automatically grips and retainsthat terminal cup in the holder and holds it therein during the entire use of the cup egainst accidental dislodgement. Holders of this type heretofore known have not always proven successful to a desired extent, owing to the fact that it was extremely difficult to remove and replace a gripping element when desired, andespecially due to, the fact that the gripping elements were not of a character to be used on cups of different shapes. That is, the same gripping element would not function with a cup substantially of a true conical shape, and also function 'witha eupjhavinga widely blunted apical portion, or with a flat bottom cup. Sometimes the grippers would not funcjtion with a one-piece cup and also a two-piece cup. Further, holders of this type heretofore known were not as economical in construction as is desired, a highly important factor, and the gripping, elements were "not as positive inaction as desired, and frequently relatively short lived.

With the foregoing in mind, it is an important object of the instant invention to provide an automatic-pickup holder for paper cups, which holder is very econor'nicali'n constructionand includes a simplified form of cup grip ping element operating upon a new principle providing a highly elfective and positive'grip u'pon theci ip.

Also an object of this invention is the provision of a pickup holder for paper cups embodying a gripping elemeht in the form of a resilient diaphragm, that 'is simple in form, economical in construction,'and so shaped and disposed in the holder as to effect an extremely positive grip on the cup, whether or not the gripping element is wet or dry. v t

A further feature of the invention resides in the provision of a pickup holder for paper cups embodying a gripping element capable of handling cups ofdifiei'eht formations, and which is readily and easily placed in and removed from the holder.

As shown on the drawings:

In the illustrated embodiment of the instant invention,

there is shown a holder embodying a hollow body part 1 provided with a cup receiving cavity 2 in its upper portion, and the lower portion of which functions as a base upon which to set the holder, the cup and its contents. Obviously, the holder may be given any desired configuration, but a generally hour glass shape is preferable when dealing with conical paper cups, such shape more nearly approximating the cylindrical in the event flat bottom cups are to be held in the holder. Equally as obviously, the holder may be made or fabricated from several pieces of material if so desired, that is the base portion and the part having the cup receiving cavity may be initially separate pieces secured together, and the holder may be made of any desirable material, both metal and thermosetting plastic being satisfactory examples.

Herein where the term body is used in connection with the holder, that term is to be construed as meaning in general the holder itself including both the upper cup receiving portion and the base.

In the upper portion of the cup receiving cavity 2, the internal face of the holder body 1 is preferably provided with a land 3 shaped to intimately fit the outer conical surface of the cup itself. Therebelow, it is not necessary that the cup contact any portion of the body part of the holder per se. The holder is also provided with an internal groove 4 defined by a pair of spaced side walls preferably horizontal, and a base Wall 5 which preferably approaches the vertical, although it may be at a slight angle to the vertical, say five degrees, for example. In the present construction, such groove is all that is necessary to hold the gripping insert now about to be described.

With reference more particularly to Figs. 2, 3 and 4, it will be seen that the gripping insert in the illustrated embodiment is molded from resilient material, rubber or synthetic rubber being highly satisfactory for the purpose. The molded and natural shape of the insert which is generally indicated by numeral 6, is that shown in Figs. 2 and 3. The insert is in the form of a diaphragm, upwardly dished or bowed as clearly seen in Fig. 3, and having a central aperture 7 defined by a common meeting line between upper and lower converging beveled surfaces 8 and 9. From this aperture, the disc very gradually thickens toward a definitely enlarged or thickened portion 10 spaced inwardly from the normal circumferential edge of the disc. This portion on its underside has a relatively wide and deep beveled surface 11, inside of which is an upwardly and inwardly extending portion 12 which merges with a conical wall 13 leading to the bevel 9. On the upper external surface, there are

twowall areas

14 and 15 at slightly different angles to the horizontal, conjointly providing a downwardly sloping upper surface from the beveled surface 8 to a relatively sharp circumferential edge further defined by the aforesaid surface 11. Obviously said edge has a diameter greater than that of the groove 4.

When the insert is snapped into the aforesaid groove 4 in the body part of the holder, the original beveled surface 11 is forced into substantially intimate contact with the almost vertical base or bottom wall 5 of the groove, and caused to assume a substantially upright position and the portion 12 is caused to assume a substantially horizontal position along the lower wall of the groove, as seen in Fig. 1. Being so confined in the holder, the insert is caused to assume a distorted shape and to become dished or bowed in the opposite direction as exaggeratedly illustrated in Fig. 4. The insert, therefore, possesses an inherent tendency to assume its molded or natural shape of Figs. 2 and 3, but is prevented from doing so by being confined in the holder.

In Fig. 1 I have illustrated the holder operatively carrying a paper cup 16 having a widely blunted or rounded apical portion 17, the gripping insert 6 positively engaging the cup in lower portion thereof above the blunted end 17. This engagement is accomplished merely by a relative axial movement between the cup and holder, the lower portion of the cup passing through the aforesaid aperture 7 in the insert.

In Figs. 5, 6 and 7 I have illustrated the operation of the holder, and in this instance I have shown a conical cup 18 having a relatively sharp or very slightly blunted apex 19. The selection of the cup 18 is for two purposes, first to indicate that the same insert 6 will handle either form of cup with equal facility, and secondly for purposes of clarity in illustrating the action of the holder.

in Fig. 5, the cup is about to enter into engagement with the insert, and the insert is in its deformed position, but the position which it must assume when confined in the holder. In Fig. 6, the cup is seated in the holder against the land 3 in the upper part thereof, and the insert has established effective engagement with the lower portion of the cup. It will be noted that the insert is downwardly deformed to a greater extent than in Fig. 5, since the cup entering the aperture 7 tends to increase the diameter of that aperture, and this can only be accomplished by a further dishing of the insert itself. This further dishing of the insert together with the inherent tendency of the insert to assume its natural shape (Figs. 2 and 3) establishes a positive grip upon the cup.

Any force tending to remove the cup from the holder will cause a buckling effect in the insert as illustrated at 2t) in Fig. 7 in a rather exaggerated manner. When properly seated in the holder, the cup is against the upper surface 8 of the insert adjacent the aperture 7, and as stated above the aperture has been stretched slightly upon reception of the cup. Consequently, a force tending to remove the cup from the holder causes the insert to move along with the cup and tend to assume its natural shape, but the edge between the beveled surfaces 8 and 9 at the opening 7 cannot pass by the cup, owing to the confinement of the insert, and the insert tends to buckle and thereby more forcibly holds the cup in place.

This holding of the cup by the insert, is not of such great strength that the cup cannot be intentionally removed from the holder, and that intentional removal is best effected by pressing with the thumb on the apex of the cup. However, the gripping action of the insert is amply sufficient to prevent any accidental or unintentional dislodgement of the cup from the holder. It is also apparent from the above description, that were the opening 7 of any other character than round, or in accordance with the contour of the cup wall, the holding power of the insert would not be as great.

While the structure above described in connection with Figs. 1 to 7 inclusive exemplifies a preferred form of the invention, another satisfactorily operating form is disclosed in Figs. 8 and 9. In these figures, a cup holder including a body 21 of the same general configuration as the holder body 1 previously described, has a cup receiving cavity 22 therein, and is provided with an internal annular groove 23 in the body wall. In this instance, however, the groove 23 in the holder body is slightly deeper and slightly wider than the groove 4, above described.

The same pickup insert or gripping element 6 is utilized in the holder structure of Figs. 8 and 9, but owing to the greater size of the groove 23, there is a relatively loose fit of the pickup insert 6 in the groove, and the pickup insert may be said to be somewhat floatingly mounted. Owing to this loose fit, the pickup insert 6 when placed in the holder remains in its normal upwardly dished shape, the same shape as seen in Fig. 3. The insert retains its natural shape, as seen in Fig. 8, until actually contacted or brought into contact with a paper cup, such for example as the cup 18. Upon contact with the cup, when the holder is pressed over the cup or the cup is pushed into the holder, as the case may be, the insert reverses its position and assumes the downwardly dished shape seen in Fig. 9. The size of the groove 23 permits the necessary shifting of the outer marginal portion of the insert when it reverses its dished shape.

While as first glance, it might appear as though the insert would revert to its normal shape after being engaged by the cup, and thus push the cup out of the holder, such action cannot happen. From the showing in Fig. 9, it will be noted that there must be a stretching of the central opening in the insert in order for it to assume its natural shape, and the insert cannot by its own inherent tendency accomplish that stretching. No actual contact by any part of the insert with the base wall of the groove 23 is necessary in order for the insert to satisfactorily hold and retain the cup against accidental dislodgement. In order to hold the cup, only sufiicient force is necessary to cause the insert to reverse its dished form. However, there will always be more force than that applied, especially when an operator places the inverted holder over the terminal cup of a stack of inverted cups in serving a soft drink or the like. The operators forceful push will not only reverse the insert, but will tend to enlarge the aperture in the insert, and thereby more effectively lock the cup in the holder. That slight additional force,over and above that just necessary to reverse the insert, is sufficient to provide the insert with a gripping action on the cup more than enough to sustain the cup against accidental dislodgement during normal usage.

From the foregoing, it is apparent that I have provided a highly economical, and highly eflicient automatic pickup holder for paper cups of various sizes and shapes. The gripping insert itself is simply molded from resilient material, is extremely economical, and may readily be snapped into or out of the groove 4 or groove 23 in the respective holder bodies. Preferably, the insert is of such size in the first described embodiment that there is a rather minute space between the bevel 11 of the insert and the base wall 5 of the holder groove when the insert is in position. Sizing these parts in that manner, to provide such a minute space, facilitates the removal and positioning of the insert.

It will be understood that modifications and variations may be effected without departing from the scope of the novel concepts of the present invention.

I claim as my invention:

1. A cup holder comprising a tubular body having an annular groove therein which groove includes a substantially vertical bottom wall and upper and lower side walls, a molded resilient disc having a central aperture therein and a circumferential edge at least partially defined by a normally beveled surface on the underside of the disc and which edge has a diameter greater than that of said groove, said disc having a normally dished shape, and said beveled surface being of a width approximately the distance between the side walls of said groove, said normally beveled surface being held in an upright position substantially parallel to the bottom wall of the groove when the disc is inserted in the groove thereby holding the disc dished in the opposite direction to enhance its gripping action on a cup extending through said aperture.

2. As an article of manufacture, a cup gripping element for insertion in a paper cup holder, comprising a resilient disc upwardly bowed and having a central opening therein, said disc prior to insertion in a holder having an outwardly and downwardly sloping upper surface and an upwardly and outwardly beveled margin on the lower surface meeting said upper surface at the circumferential edge of the disc.

3. As an article of manufacture, a cup gripping element for insertion in a paper cup holder, comprising a resilient disc upwardly bowed and having a central opening therein, said disc prior to insertion in a holder having an outwardly and downwardly sloping upper surface and an upwardly and outwardly beveled margin on the lower surface meeting said upper surface at the circumferential edge of the disc, said central opening being defined by two other upwardly and downwardly intersecting beveled surfaces.

4. As an article of manufacture, a cup gripping element for insertion in a paper cup holder, comprising a molded resilient disc upwardly bowed and having a central opening therein, said disc prior to insertion in a holder having a thickened portion tapering outwardly to a narrower circumferential edge, and said disc gradually decreasing in thickness inwardly of said portion to said opening.

5. A cup holder comprising a tubular body having an annular groove on the inside thereof, a resilient dished disc having a central aperture therein to grippingly receive a part of a cup seated in the holder, the upper surface of said disc sloping downwardly to a relatively sharp circumferential edge further defined by an annular beveled surface on the underside and which edge has a diameter greater than that of said groove, said annular surface being held in an upright position when said disc is inserted in said groove to hold the disc dished in the opposite direction against its inherent restorative tendency and enhance the gripping action of the disc on a cup extending through said aperture.
