To all whomv t may concern:

Be it known that I, JOSEPH V. Wncn- BAUGH, a citizen of the United States, and

Ya resident ofJNew' York, ,in the county of to be suitable for packingV and sale.

The invention has for its object to provide a cup of this type from a suitable blank as of paper which is folded in `an extremely simple manner to provide a Yliquid-tight container having a large capacity for the amount of material employed. A further objectv of the invention consists in providing a substantially rigid mouth- Vpiece or lip' therefor and the edge of which shall not be sharp, asis the case usually with cups of the types heretofore' produced. The cup, moreover, lendsV itself readily to manufactureV in a sanitary manner. `For ex-V ample, it maybe produced Afrom a continuous strip of material which will require no handling, the said material, also, remaining sealedV or enclosed until the actual time of manufacture', and the cup being capable Y of being manufactured and dispensed entirely by mechanical means. The present applicationis a division of my U. S. Letters Patent No. 1,359,772, granted November 23, 1920. Y

vIn the accompanying drawings, which illustrate the invention- Figs. 1 to 4c are diagrammatic views illustrating the different stages in the manufac-' ture of a cup.

Fig. 5 is a perspective view of a completed cup. Y

Similar characters of reference designate corresponding parts throughout the several views.

Referring to the drawings, 10 designates a blank composed, for example, of a suitable grade of paper of the required thickness and stiffness. This blank may be obtained in desired lengths as from a continuous strip 11, being cut therefrom along the lline 12 to provide a parallelogram of substantially equal sides and generally in the form of a square. One of the corners, for example, the corner 13, of the blank is turned backwardly along a line 14 perpendicular to Vthe diagonal 15 of the parallelogram, and the blank itself is then turned over about the-said diagonal 15 as an axis or folded along same, whereupon the fulllength edges 16 and 17 are securedto each other in any suitable manner, for example by folding same inwardly. I prefer, in order to facilitate the turning and folding operations and final shaping of the cup, to crease or provide line impressions along the said diagonal 15 and line 14 perpendicular thereto as well as along theedges 16 and 17. Also additional radial line impressions 15 may be provided at either side of the diagonal. The edges may be securedto each other by means of a suitable adhesive, or may be folded over again, or preferably, are

lsecured by means of a suitable binding strip Vor metal tape-18 which is bound over same, Fig. 4.-. This completes the cup .which is thus securely sealed approximately from bottom to top along the lengthwise edges 16 and 17, in manner indicated, providing, also, a suitable mouthpiece 19. The latter is reenforced and .stiffened by the backwardly `turned corner 13, which serves,

also, to hold the cup open as well as to round off'r that portion ofthe cup coming Yin l.contact withthe mouth', thus obviating --the sharp edges now found in thepaper cups in general use. It is to be noted, in

this connection, that if the paper for manufacturing the l.cup -be taken from a strip Asuppliedin the form ofa roll, the inside surface is not exposed YtoV dust and air and alsoneed not behandled during the process of .-manufacture, thus insuring a sanitary product.

In the manufacture of these cups in quantity and by mechanical means, the material for the blank 10 is provided by feeding forward the strip 11 of paper and simultaneously ltherewith a strip 18 of binding material such as metal. The latter is preferably arranged to be vfed beneath the paper 11 along one edge thereof' and at a slightly lesser rate than that of the strip in order to make use of the same feed rolls for both and to` effect a saving of metal.

ylll/'hen the requisite quantity has been fed forward, both paper and metal strip are cut along the line 12 to provide the blank 10. Thereupon, or simultaneously with the feeding of the material, suitable means are caused to deflect the corner 13, preferably at an an le of fort -ive degrees to the direction 0% travel ofy the paper, after which the deflected portion is gripped and turned under, and the line impressions made therein. The entire blank isl thereupon turned over abouty the diagonal 15 as an axis, orv

folded along said diagonal. The, strip of metal 18, together with the coactin rlengthwise edges 16 and 17, is then fol ed over and secured or bound together.

When a metal strip,- as the strip 18 is employed, the same is designed to be clamped over the said edges; and to this end is preferably formedv with perforations equally spaced along its median line, the same. facilitating the bending ofthe Strip in order to clamp the material. Moreover, the edges of said perfonations are, left rough .upon the inner Side, thereby insuring a maximum4 hold. on the paper or` flexible material.

I' claim:

1. A pliable metal cIampngstrip for the registering edges of a paper container, adapted to be fed by a sprocket wheel and having perforations arrangedflongitudinally thereof tol aford accuratefeedl of the strip and tok insure bending ofI the strip moet readily' along the line of. perforations.

2. A pliable metal clamping strip for the registering edges of a paper container, adapted to be fed by a sprocket Wheel.- and having perforations arranged along its median line to ai'ordi accurate feed ofthe strip and to` insure bending of the strip most readily along the said median line.

3. A pliable metal clamping strip for-the registering. edges of. a paper container, adapted to be fed'by a sprocket wheel and having perforations arranged longitudinally thereof to afford accurate feed ofthe strip and to insure bending of the strip most readil along the line.` ofl perforations, the sameV eing roughened along their edges to provide a secure hold by the strip.

4. A pliable' metal clamping strip for the Vmedian line to afford accurate feed of the strip and to insure bending of the strip most readily along the said median line, the said perforations being roughened alongk their edges to provide a secure hold by the strip.

5. A drinking cup consisting of a paper blank substantially in the form of an equi,- lateral parallelograni, folded backwardly at one corner along a line perpendicular to the diagonal of the parallelogram and turned about said diagonal, and having its lengthwise edges secured to each other.

6. A'drinking cup consistingof a paper blank substantially in the form of a square, folded backwardly at one corner along a line perpendicular to the diagonal ofthe square and turned about said? diagonal, and having` its lengthwise edges secured to each other.

7. A drinking cup consisting of av paper blank substantially in the form of a square, folded backwardly at one corner along a line perpendicular to the diagonal ofthe 'square and turned about said diagonal, and

having its lengthwise edges secured to each other, and a metal strip turned over the lengthwise edges.

8. A drinking. cup consisting of a paper blank substantially in the form ofl an equilateral parallelogram, folded; at one corner along a line perpendicular to the diagonal of the parallelogram and turned about said diagonal, and having its lengthwise edges securedI to each other.

9. A drinking cup consisting of a paper blank substantially in the form of an equilateral parallelogram, folded at one corner along a line perpendicular to the'diagonal of the parallelogram, said corner having a series ofv impressions along its folded edge, the blank being also turned about the said diagonal and having its lengthwise edges secured to each other.

Signed at New York, in the county of! New York and State of New York this 12th day of July, A. D. 1920.
