f UNITED sTArEs PATENT OFFICE Vortex tion of Delaware' cup lll., s mur Appunti@ september 2s, 1934, No. mais o 7 o lum. (ci. 22o- 1.5)

This invention relates to'utheart of paper rej ceptacles, and more particularly 'to individual par;

per cups of the type disclosed in my .United States Letters Patent No. 1,8'70,223, .granted August 9, 1932. j

-An object of thisvinventio'n. is to rovidean improved cup of the open or self-extended type which is vbetter adapted'to resist any tendency to collapse it during dispensing or use of the same.

Another object of the invention is to so improve aV cup ofthe above-noted type that the open end of the cup is forced to assume .a'shape which more nearly`approximates a circle.

A further object of the invention is to depress the wall bf a cup in such a manner and at such points as to cause the cup tobe better able to re'- tain an open shape in condition for immediatel In accordance with the general lfeatures of this invention,l there is provided ajcup having a body t portion Vadapted when in use to present a substantially rounded mouth and being of open form,

'tapering' "from itsmouth in wedge-like 'shape to a tight bottom closure made by a straight edge transverse fold-upof the cup material secured to the'body portion, thewall of the body portion' iiedforms of cups embodying features of the blank .shown in Figure 1.

invention, in one form of whichthel rib-like depressions extend substantially the' full length of the cup, Whereas. in`V the other form the rib-like depressions do not extend the full length of the. cupbut are disposed in an intermediate position between the top and bottom of the cup.' f

Itis als'o the aim of this invention-to provide van.improved;method ofj making a cup having the foregoingfeatures. However, it is thought'tliat 'Y my, novel method will be fully understood from v a description of a, cup

made as a result of the use of the method.

Other objects and features of this invention will more fully appear from the; following detailed '1. description taken in connection with the accomy panying drawings, which 1ll us\trate-several-em bodiments thereofLandin which wFigure l-isa view. of a'pap`er blank froniiw'hich my novel cup i s made. Figure 2 is a top view o f a cup made hfrom the Figure 3 is a side view of'this cup. Figure 4' is a top view of the samecup after the. cup has had opposite depressed ribs incorporated therein 'involving the features of this invention. v o Y Figure 5 is a sideview of the cupshown in Figure'i.l 5

Figure e is a .v'1sw` of a mourned blank from which a cup. embodying this invention can also beconstructed.. m

Figure '1 is a side view of a cup maqerrom thel blank shown in Figure 6,- and having depressed 1'0 modiiied orm of cup similar to that shown in Figure 5 but diifering erefrom in thatthe lonl5 gitudin n ribs d o'note d the run length of thei cup. L

'.As shown o n the drawings:

The reference character- I0 designates geh-V' erally ablank which may be made from paper 20 or any other suitable material and from which a cup embodying the features of my invention is adapted. tovbe constructed. blank has convegingside edges gli and I2 which attheir outer extremity terminates in avcurvededge |315 adapted to denne the rounded mouth of the cup.

'Theinner extremities of the side edges II and I2' .terminate in a fold-up portion designated generallyby 'the reference character I4. This foldup Ais adapted tol be folded about transverse liles 30 'of foldindicated by dotted lines and designated I5 and I'I'to the line I6, the lin'esHIS and I1 will 40.

bedirectly over the line I64 when the `blank is folded intoI a wedge-shaped cup. When thus vfolded, they will define a transverse straight-edge I8 (Figure 3) at'the bottom of the cup. VThis, edge I8 will 'be located at theline It (Figure 1). 45 l The portions of the cup blank between the lines A|5516 and 'I1 and-the bottom extremity ofthe cup comprisesin 'reality a plurality of superimposed layersin the resulting fold-uli. Il' shown in' Figure 1: .The portions of the cup which are 50 adapted to be thus formed in superimpod layers tion 20 of' the fold-up has an extension or adhesive tab 22. In other-words, the layer or por- 55 tion constitutes an exterior layer `which is llightly longer than the underlying layers i9 and :I'he side of theblank `Il) at the edge l2 is provided with a strip of adhesive designated by the reference numeral 24. This marginal portion with the strip of adhesive thereon is adapted to be overlapped by theside portion ofthe blank adjacent the edge Ii and to be glued to that portion, as will be evident from Figure 3.- Thereafter the fold-31p Il is turned upwardly about the line I6 and is glued to the side of the cup over the overlapped side edges by means of adhesive on the tab 22.

This results in the cup being provided with a water-tight straight edge transverse fold up at the bottom o! the cup.

In the formation of the cup from the blank lill the blank isl rolled upon any suitable apparatus such, for example, as a mandrel, into the wedgelike form shown in Figures 2 and 3. In this form the cup has a rounded mouth and is creaseless. In other words it is oi a self-extended open i'orm tapering from its mouth in wedge-like form to the say, these depressions areformed in the cup asv far downy toward the bottom of the cup as the structure 'will permit without distorting or damaging the bottom closure. 'Ihese depressions are diametrically opposite and are formed in the diametrically opposite narrow sides I3 yand il o! the cup shown-in Figure 2. In Figure 2 it will be perceivedl that the cup has an elliptical cross-` sectional shape. It is at the narrow sides Il and 34 i' this cup oielliptical cross-sectional shape that I form the depressions Il and 3| shown in Figures 4 and 5.

These depressions, may be formed by any suit- V able apparatus. I nnd that they may be incorvso porated in the cup by disposing the cup over a mandrel of proper cross-sectional shape and by thereafterrunning ribbing fingers over the

edges

33 and 34 of the cup. In carrying out this operation the pressureon the sides or edges 33 andl u of the cup presses these ,narrow end sides or edges inwardly so that,the open end of the cup is caused to assume a shape which more nearly approximates that of a circle. In other words.

.the cup is opened to a still further extent so that,-

it is in effect changed from a cup having an open end of an elliptical crpss-section to `a cup having an end of substantially a circular cross-section as shown .in Figure 4. y

In Figures 6 and 7 I have illustrated a modified iormo'f theV invention in which the'principal dii'- ference resides in the change of the location ot the adhesive tab 22 as well yas the location oi' the strip of adhesive 24. The `cup in this form. oi the invention is made from a blank it having converging side edges Il' and I2' terminating at their outer ends.in the lcurved edge i3' ior deilningthe open end ofthe cup. 'Ihe inner extremities of' these side edges terminate in a foldup I4' made up of three plies, the outer layer of form an extension or tab 22. This fold-up is folded about the transverse straight edge I8' as shown in Figure 7.

In this form of the invention the extension taby '22', instead of being formed in a central position with reference to the side edges, is formed adjacent one of the side edges li so as to in effect constitute an extension of that side oi the blank.

This enables a single strip of adhesive 24' to be applied in a substantially straight line along the side edge Il" and also on the extension tab 22. f

In Figure 8 I have illustrated a modiiica'tionv of the first form' of the invention in which the only dierence resides in the fact that the ribs length of the cup butterminate below 4the open g end of the cup as indicated at and Il. With this exception this form oi.' the invention is like the form shown in Figure 5. i

Iam aware that many changes may be/made and numerous details of construction may be varied through a wide range without departing from the principles of this invention, and I, therefore. do not purpose limiting the patent granted hereon otherwise -than necessitated by the prior art.

I claim as my invention: 1.- A cup having a body portion adapted -when in useto present a substantially rounded mouth land' being o! open form tapering from its mouth in wedge-like form to a tight bottom closure made by a straight vedge transverse fold-up of' the cup material secured to the body portion, said' cup having substantially a non-circular cross-sectional shape below its rounded mouth the wall of said body portion having longitudinally ex.
