DRINKING CUP.

Application filed February 16, 1927. Serial No. 168,546.

My present invention relates to a drinkin cup and more particularly to that type 0 drinking cup made of paper or other similar material and foldable to assume a normally flat position and the parts of which are adapted to be spread or separated for use. I am aware that heretofore various forms of this 'type of drinking cup have been made and used, examples of these are that type in which the cup is formed to comprise obverse and reverse members having substantially parallel sides and provided with flaps by which the cups may be removed from a superimposed pile thereof; that type in which the cup is constructed to taper from a relatively narrow closed end to a'relatively wide opened end; and that type in which a parallel sided cup has been provided at the open end thereof with a spout for the supposed purpose of aiding or directing the liquid inits flow from the cup in the use thereof. In this and other similar forms of foldable drinking cups made of paper and similar material there is more or less difliculty as well as inconvenience in -the use thereof. Oftentimes, due to the set formed in the paper by the piling and packing of the cups they do not readily open as intended; obviously .in that type of cup in which the sides taper from a relatively narrow closed end to a relatively wide opened end there is a tendency of the liquid to flow too fast from the cup in the use thereof. Furthermore, in the construction of drinking cups of this type, the flaps which are employed to close the cup are folded in such a manner that the seam 1s of varying numbers of piles of material from which the cupk is w en placed together thicker in certain portions than others which is an obvious disadvanta e in ackin the cups.

e o ject o my invention is to overcome these difliculties and to provide a cup of the -tvpe to which the invention relates in which there is a relatively wide closed end and a relatively narrow open-end, the open end bein preferably provided with an extension for irecting the flow of the liquid from the cup tothe mouth of the user whereby as will be a preciated due to the taper of the cup the ow of the liquid is more or less retarded and in any event does not rush from the cup to the mouth of the user. Furthermore, in carrying out the invention the blank from which the cup is formed is so constructed that the flaps, by which when folded the closed end of the cup is formed, provide a uniform thickness of the seams by which the closed joint in the cup is made. Still furthermore, in carrying out the invention, the adhesive is so applied to the corners of the interfold flaps as to insure a liquid tight joint at the closed end of the cup. These and other features of the drinking cup made in accordance with the present invention will be hereinafter more particularly described. When formed, my cup presents substantially similar reverse and obverse sides of trapezoidal shape, the bot tom closed end of the cup being the base of the trapezoid and being the longer of the two parallel sides of the trapezoid, the shorter opposite side definin the open top end of the cup. The opposite ateral edges of the obverse and reverse sides, defining the two other opposite lateral sides of the trapezoids, substantially converge toward each other as they extend from the bottom to the top of the cup, which results in forming a receptacle m which the width of the obverse and reverse faces,'at the top open end of the cup, are substantially less than the width of these faces at the bottom closed end.

' As the result of the shape and combination of the parts forming my cup, when in use, the obverse and reverse faces diverge from each other as they extend upwardly from the closed bottom to the open top, the points of greatest divergence of these faces bein at the edges defining the open top end 0 the cup.

Fig. 5 is a section on line 5-5, F g. 3. Fig. 6 is a section on line 6-6, F g. 4. Fig. 7 is a section on line 7-7, Fig. 4.- Fig. 8 is a partial elevation showing another form of blank, and

Fig. 9 is an elevation of the closed end of a cup when made in the form of the cup illustrated in Fig. 8.

7 Referring to the drawing and particularly forming an obverse side of the cup. These parts are spaced with their limitations determined by fold lines 13 and 14.. One end of the blank is provided with an extension at the corres ending end of the reverse-side 10 and the ad acent edge portions of the flaps 11 and 12 are cut away substantially as illustrated in this figure of the drawing in order that when folded to position a lip 15 is provided at the open end of the cup for directing the flow of the liquid from the cup to the mouth of the user or otherwise as may be desired for example in pouring liquid from the cup.

At the opposite end of the blank the reverse side 10 is extended to provide a fla 16 and the corresponding ends of the flaps 11 and'12 are extended to provide. flaps 17 and 18. Also as illustrated in this figure, the op posite ends of the flap 16 merge with the adjacent ends of the flaps 17 and 18, that is the flaps 17 and 18 form continuations of the flap 16 and are not separated or divided therefrom.

In forming the blank in addition to the fold lines 13 and 14 which maybe formed by suitably creasing the material, the blank is also provided with a fold line 19 at the flap end of the reversemember, and fold lines 20 and 21 at the flap'ends of the flaps 11 and 12. In folding the parts of the blank to position the flap 11 is first folded over on theline 13 and the flap 12 then folded on the line 14 so that the parts-then assume a position as illustrated in Fig. 3, in which the fold line 20 is in alignment with the fold line 19 and also the fold line 21 is in alignment with the fold line 19. At this point in the description it is to be noted that the flap end of the flap 11 is cut away as indicated at 22 and the adjacent and of the fla 17-as indicated at 23, while corresponding the flap end of the flap 12 is cut away as indicated at 24 and the adjacent end of the flap 18 as. indicated at 25. The outer extremity of the fold line 20 terminates in this cut away portion of the flaps 11 and 17 as indicated at 26, and the outer end of the fold line 21 terminates in the cut away portion'of the flaps 12 and 18 as indicated at 27. The construction is such that when the parts are folded as hereinbefore described the ends of these fold lines 20 and 21 assume a superimposed position, that is the end 27 ofthe fold line 21 is superimposed on the end 26 of the fold line 20 in a point asindicated at 28 for a purpose which will presently appear.

The edge portion of the flap 12 is provided with a suitable adhesive material as indicated at 29,- and the flap 16 is provided with an adhesive material as indicated at 30 which is extended across and made to cover adjacent portions of the flaps 17 and 18 as indicated at 31 and 32 respectively. It will now be understood that in making the told as hereinbefore described the adhesive material 29 on the flap 12 connects this flap to the flap 11 and that the adhesive'material on the flaps 17 and 18 overlies the adhesive material on the adjacent surface of the fiap l6 and provides what may be termed a double supply of adhesive to these superimposed portions of the flaps to assist in insuring a liquid tight joint at the closed end of the cup. The other portions of the flaps 17 and 18 are also caused to adhere to the adjacent or underlying portions of the flap 16 due to the fact that the flap 16 in its substantial entirety is provided withthe adhesive material.

In completing the closure the flaps 16,17 and 18 are folded on a line 33 which is coincident with the then superimposed fold lines 19, 20 and 21. This causes that portion of the gummed or adhesived inner surface of theflap 16 which then extends beyond the edges of the flaps l7 and 18 to adhere to the outer underlyin surfaces of the flaps 11 and 12. It will now e understood that because of the cut away ends of the flaps 11 and 17 and the correspondingly cut away ends of the flaps 12 and 18 that portion 23 of the cut away end of the flap 17 conforms substantiall with the cut away end portion 24 of the ap 12, and correspondingly the cut away end portion 25 of the flap 18 corresponds substantially with the cut away end portion 22 of the flap 11 so that in this portion of the joint there are only three plies in all parts In this form of the invention the end portions of the flap 16 are so formed that when the flap 16 is turned to place these end portions lie'substantially parallel with the cor responding edges of the cup as is clearly indicated in Fig. 4 of the drawing. In some instances, however, as shown in Figs. 8 and 9, the end portions of the flap 16 may be extended as indicated at 34 and 35 and after the flap 16 is folded to position these end portions 34 and 35 thereof may be turned over the tapering edge portions of the obverse and reverse members of the cup and secured to the underlying adjacent surface of the reverse side of the cup. This feature, however, is a detail of construction which is no necessary part of the invention.

'As illustrated in the drawing the reverse member is provided with a crease line 38 extending in a substantially centrally disposed position from the open end of the cup an appreciable distance toward the closed end of the cup. This may be provided to cause the cup to more readily open by compressing the tapering side edges thereof. It will be understood, however, that this crease line may be dispensed with or instead of being placed in the reverse side ormember may be placed in the obverse side or member with the same results.
