M 90mm? tion of Maine sppuci ssatet 931, Serial nassmsz The present invention relates to paper ing. cups 1.01; the type which are adapted: for .fla't. packing 111:2.10011'5811181' but which are opened:

for use as theyarewithdrawn from thec'on;

It has been'propo'sedheretofore provide paper cups which are packedin a flat condition and are opened; for, use .byI-pressure on. opposite edges.

these cups being; ingeneral, triangular in" shape only by grasping it along theconverging sides with:

when fiatp, Often times these'cupsfdo not open readily from the ;flat.,condition, since, under pres-1 sure applied to opposite edges, both sidesgspringin thesame direction: instead of away from each, other as theyshould, to open. the cup, or the sides I buckleysothatv the cup opens unevenly. Moreover, this type: of ,cup supported in: the hand the result that the cup, when in use tends ftO slide upwardlyout, of'the hand'or Ito crush by reason of the'pressure exerted-in grasping it. 1

The objects of theypresent .inventionpare' to.

provide a cup 10f the. flat packing-typewhich-is;

self-extending into open cup forms .asjit is with:

drawn'from the container, and which presentsa surface of substantial :width" along the bottom for the jusers hand or; finger by means, of which the cup is supported without exerting undue pressure on the sides thereof; Other objects and advantages-of the invention will be apparent from the following detailed; description thereof taken in connection with the accompanying drawing,v in -which:- 1:1 L

Fig. 1 is a plan view of a blank from which a cup embodyingtheinvention is formed.

Fig. 3 is a plan view of a completed cup formed from the blank of Fig. 1. e V

Fig. 4 is a fragmentary sectional view of a container. showing the manner in which the cup the outer edge thereof. The bottom edge 33 of the blank is provided with a central bottom flap 3! opposite the flap 34, said bottom flap being v somewhat "smallerthan said flap 34'; both trans versely andloxigitudinally. "The side edge 3| of the blank-is providedrwith a tabior-flapifl adj wentthe upper .end thereof the tab providing means bywhich thecup maybe removed from the'con-s taineras will hereinafterappear. 4

The blank, provides 'a central body poms; 14b v defined by jfold lines ,4! ,;and- 42, which ,extend vertically :of the cup-adjacent. opposite edges of the bottom flap 31, iand sideflapsJii, and 44 defined respectively by the side edges and 3l and fold lines 45 and 46, thelatterv extending parallel to and in spaced relation togthelines 4| and. The portions of the. blank .betweenthe fold lines 4! and 45 and similarly between the-fold lines 41 and 46 comprise; end-forming portions "and 48 eachof whichfhasa'fold orcreasefSII, 5| extending reversely;to ;the' folds 'or creases 4| and 45, 42 and 46 respectively; The folds .or creases 50, 5 l l are ,located near e fv to the folds or creases '45 and 461than:t o =the folds increases-4| and 42 for a purpose which will;hereinafter-appear;

Informingthe cup the side; flap43 is first fQ1ded' iIlt0f overlapping-engagement with the centralportionjw theend-forming portion 4'! being 'arrangedas shownmost clearly in Figs. 2 and 4 between the, portions and-43, i the fold edge 50 extending inwardly; ,The fold at is laterally separated from the 7 fold 4 l and lies] within the area of the central body portion 40,"

as will be apparent from Figs. 3 and spy reason of the spacing ;of;-fold from: folds, 4 land 45.

The opposite 1 side. flap 44 is next folded into=- ov lappin en g me w h t e centr nor-I- tion luandwith the dee-ofa h rflap JMth o d edge 5| extending inwardly between the portions 40 and 44 and the fold line 42 extending outwardly beyond thefold line 46 by reason .of the location of fold 5|. flaps 43 and 44 are secured together inany suitable manner, after which the bottom portion of the cup is folded upwardly along the line 52 against the overlapping side flaps 43 and 44 and secured thereto. The fold-up of the bottom portion along the line 52 provides a straight-line bottom closure for the cup and provides watertight corners at opposite ends of said closure as will be apparent. The upper portion of the drinking lip 34 is folded against and secured to the remainder'of the lip thereby to provide a reinforced drinking edge, and the tab 38 is folded against the side flap 44.

Thecompleted cup thus formed is substantial ly in the form of a wedge having a front portion 40, Fig. .5, a back portion comprisingflaps 43and The overlapping edges of V 44 and end portions 41 and 48 providing, when the cup is in open position, a substantially rectangular open mouth, the cup decreasing in cross-section to the straight line bottom fold 52. The front and back portions of the cup remain substantially planar either in the open or in the" is of substantially greater width than the back portion composed of the side flaps 43 and 44, the creases 45 and 46 which define the opposite edges of the back portion being substantially spaced, from the corresponding creases 4i and 42' re-' spectively.

a dispensing container for the cup is shown in cross-section, it will be notedthat the container providesa dispensing.. opening 5t .of a.v width somewhat greater than the width: ofthe back portionof the cup but oflesswidth than the front portion thereof; the edges 5 and 5 of thedispensi-ng opening thereby engaging the outer edges of the cup between the-fold lines and 45,12 and respectively. As the cup is grasped by the tab 38 for removal from the container, it will be seen that the edges 55 and 56 retain the front portion 40 of the cup against movement until the backportion has been substantially separated therefrom, that is, the cup has been opened to substantially its greatest size. The material of the cup is sufliciently flexible to permit the front portion to bend orbuckle-afterthe cup is extended, therebyto' permit the cup to be entirely removed from the container. It will thus be seen that the cup is automatically distended as it is withdrawn from the container and is thus automatically madeready for use without any necessarymanipulation by the person using the cup. -The natural resiliency ofthe material of the cup is sufficient to cause the tab 38d of the succeeding cup within the container to spring away to a slight extent from the portion of the cup against which it is folded, thereby providing a handle for the cup which may be easily grasped by the user when the succeeding cup is to be withdrawn from the container. 5

weclaimz r 1. A paper cup for use in a di'spensing' con tainer; the latter having a dispensingopening with supporting lips on opposite sides thereof, said cup having side and end walls, said end walls having reentrant creases to provide for collapse of said cup to a fiat condition, one of said side walls being substantially wider than the other of said side walls, the wider wall being somewhat wider and the narrower wall being somewhat less wide than the spacing between the supporting lips of the container to provide for passage of the narrower wall between said lips and to prevent accidental passage of the wider wall therebetween.

2. A paper cup for use in a dispensing container, thelatter having a dispensing opening with supporting lips on opposite sides thereof, said cup having substantially plane side walls, end walls connectingfsaid side walls and having reentrant creases therein to provide for collapse of said cup to a flat condition, said side walls Referring now to Fig. 4, in'w-hicha portion'of beingunequaim width, one of said side walls being widerand the other side wall being narrower than the spacing between the supporting lips of the container to provide for passage ofthe narrower-wall between said lips with the latter restraining. the remainder of the cup from unintendedpassage between said lips.
