terial, from which the' cup is formed, said blank comprising two' corresponding fiat members 16, 17 and having a crease line 1S @on one face defining the 'central transverse division between said members; lhe niemrging side edges extending -to the ends' of the crease line 18, and in addition the members 16, 17 are formed with crease lines 19, 20, 21, the 'crease lines 19 being transveliseiof the blank yand equally spaced trom th central transverse line 18, and the crease lines 20 being extended lengthwise et' the blank parallel with each other from one crease line 19 to the other crease line 19 and reasonably adjacent to the side edges of the blank, while the crease clined lines from the ends of the longitudinal crease lines 2O to the crease line 18. The

, crease line 1S defines the line on which the blank is folded, and the other crease lines referred to come into use only when a pros- I pective user of the cup desires to convert the lower end ot' the same into atiat supporting bottom.

After the blank .has been folded on the line 18 and the members 16, 17 have beeii brought in tace to tace contact, the adjacr yc side edge portionsof said members are securely fastened tdgether and latwise against each other to form a fiat receptacle by means of binding strips 22, preferably of metal, which extend from the upper to the lower edges of said members and are 'approximately of U-shape in cross-section Ato receive and be firmly compressed against said edge portions of the members 1G, 17 so as to bind said members together without other means than the pressure of the opposite sides ot' said binding strips. 'Initially the binding` strips :22 extend slightly above the upper edges' of the members 16, 17 and thereby form projecting portions 2d.. shown iii Fig. ritter the strips 2:. have been applied to the side edges ot the inembers 16, 17 to create the construction shown in Fig. Q, said binding strips are t'olded over or turned inwardly toward cach other against 7the outer face ot' one ot' said members; in this instance the member 1G, and the upper projecting end portions 23 of said binding strips are 'then bent.lateially and downwardly against the inner face ot' said member 1S, leaif'ing the upper ends of the binding strips smooth and securing said strips against the outer face of the member 16, thereby creating the construction shown iii F ig. 1. Vi'hen the cup has reached the stage illustrated in Fig. 4, it will have been entirely completed and be ready for the market, the cup then being flat and formed of two integral sides fastened together at their vertical edges by the strips 2Q, with no paste or other adhesive present.

rThe finished cup discloses the crease lines 19, :'20, 21 as a guide and aid to the user of the cup in fashioiiing the lower cud thereof into a flat bottomadapted to support tho cup oii a table, 'tray or the like. The hat cups shown in 'Fig'. l may be very convcn ieiitly carried both iii stock by a dealer and iii the pocket by persons desiring to use the cups. The cup shown in Fig.- 4 is :i fat cup as distinguished from what is commonly 75 called a formed-upf cup or one which is permanently in circular shape and has a fixed flat bottom. The paper used in the cup is flexible and of water-proof character and preferably devoid of any wax or other surface-coating. When it ispdesired to use the cup ot my invention a person may by pressing in wardiy on the middle portion of the bottom edge thereof, cause the paper ot' thc cup .to bend at .right-angles to the side members 16, 17 on those portions of the crease lines 19 which are intermediate the crease lines Q0, as indicated in Fig. 1U; and

.opposite side or hound edges of the cup slightly toward each other and open out or distend the. main body portion ot the hotly of the cup, and in addition the liattening of the central portion of the bottom of the cup will form and vleave projecting dowi'iwardly trom the told lines 20, two triangular end .sections 2l which may then be folded iiiwardly on the crease lines il() and those portions of the crease lines 19 which are outwardly beyond the lilies 20, against the flat portion defined between said lines 2O and the middle portions of the lines 19, :i rectangular flat bottom being thus created. as shown in Fig.' 11. suitable to support the cup and such contents as may he placed therein. along the sections 2l, and when said sections are folded inwardly to aid in creating the flat bottoni, said strips serve to preserve the iiitegrity of the flat bot-tom and thus materially aid in creating aV durable structure and a cup oi such stability as to render its use both convenient and safe.

lily invention, therefore, comprises a desirablecupstructure which is initially flat. and which has on its side members guiding maiis or crease lines enabling a user to properly and conveniently convert the lower end of the cup into a fiat supporting bot.- tom `which without any added means serves to maintain the cup in expanded condition ready for use. v

l/Vhat claim as my invention and desire to secure by Letters Patent. is:

V1. As a new article of manufacture, an initially flat. drinking cup of paper or the like comprising a transversely folded blank 180 the faces of whose side members are clamped together liquid tight at their adjacent side edges and bear adjacent to their lower ends crease lines to guide the usei. in converting the lower end of the cup into a flat bottom on which the cup may stand.

2. As a new article of 'manufacture an initially flat drinking cup of paper or the like comprising a transversely folded blank the faces of whose side members are clamped together liquid tight at their adjacent side edges and bear adjacent to their lower ends crease lilies to guide the user in converting the lower end of the cup into a flat bottom on which the cup may stand, said crease lines extendingtransversely of said members suitably above the folded lower edge of the cup, vertically between said transverse lines inwardly from the side edges of said members and downwardly and outwardly from the upper ends of said vertical lines to th lower edge ofthe cup.

As a new article of manufacture, an initially flat drinking cup of paper or the like comprising a transversely folded blank forming the side members of the cup, and bendlable stitfening strips clamped upon and holding together liquid tight the adjacent side edges of said members, said members having adjacent to their lower ends crease lines to `cuide the user in converting the lower end of the cup into va fiat bottom on which the cup may stand.

l. An initially Hat drinking cup of paper or the like comprising atransversely folded blank forming" the side members of the cup, and bendable stiffening strips applied to and binding together. the adjacent side edges of said members, said members having adjacent to their lower ends crease lines to aid the user in converting' the lower end of the cup into a flat bottone and said lincs extendin n transversely of said members above the lower folded edge of the cup, vertically between said transverse lines at points set inwardly from the vertical side edges of said members and diagonally downwardly and outwardly from the upper ends of said vertical lines to the lower edge of the cup.

As a new article of manufacture7 an initially flat drinking cup of paper or the like comprising a transversely folded blank forming the side members of the cup, and bendable stidening strips clamped upon and holding together liquid tight the adjacent side edges of said members, said members having adjacent to their lower ends crease lines to guide the user in converting:y the lower end of the cup into a 'lat bottom on which the cup may stand, and said strips being of metal and of U-shape in Icross section and receiving between their side portions the facet0face edge portions of said cup-members. y n

6. As a new article of manufacture, a drinking cup of paper or the like comprising a transversely folded blank constituting the opposite side members of the cup7 and stil-lening stri s clamped upon and holding together liquid tight the adjacent side edges of said members7 said strips being folded over inwardly parallel with said members and having their upper ends which normally project above said members bent laterally and downwardly against the inner face of the member whose outer face is engaged by them.

7. s` a new article of manufacture, a drinking cup of paper or the like compris ing a` transversely folded blank constitutin the opposite side members of the cup7 an bendable strips clamped upon and holding' together liquid tight the adjacent side of said members, said strips being of metal and of U-sliape in cross section and receiving` between their side portions the face-toface edge portions of said cup-members, and
