BLANK FOR PAPER BOXES.

SPECIFICATION forming part of Letters Patent N0. 634,507, dated October l0, 1899. Applica-tion filed May S, 1899. Serial No. 715,999. (No model.)

To CLZZ whom t may concern:

Be it known that I, HARRY B. SMITH, a citizen of the United States,residing at New York, (Brooklyn,) in the county of Kings and State of New York, have invented certain new and useful Improvements in Blanks for Paper Boxes; and I dohereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appert-ains to make and use the same.

My present invention relates to certain new and useful improvements in box-blanks, and more particularly to blanks for forming paper boxes.

It is the prime object of the invention to provide an extremely cheapand easily-constructed blank for forming paper boxes having curved or rounded 4corners, the bottom, ends, and sides of the box being formed from a single blank, and the Wings forming said ends and sides being constructed in such manner as to form when folded up into position a smooth unbroken surface around the entire outer circumference of the box, no overlapping parts whatever vbeing present in the structure, which is one of the essential and distinguishing features of the invention.

The demand for a paper box having curved or rounded corners 'is very great at the present time; but as heretofore constructed it was impossible to obtain such a box at a price low enough to enable its general use in connecf tion with articles sold at a nominal price. Furthermore, boxes now upon the Vmarket having rounded corners, so far as I am aware, either have crimps or folds at the corners or are formed with overlappingportions or edges,

Which render such corners unevencumber some, or bulky, and otherwise detract gener# ally from the neatness of the box.

Briefly stated, my. invention comprises a box-blank made from paper or card board and consisting of a body portion of any desired shape having its corners rounded orcurved and provided with side and end Wings or flaps `which have the opposite ends thereofcut off or removed to such a degree or extent as that when vfolded up to form a box the adjacent edges of'said Wings or fia-ps will abut against each other to form a close t, but will not overlap each other, thus producing a smooth andcontinuous unbroken surface around' the outer circumference of the box.

In order to enable others to construct boxblanks and boxes in accordance with my invention, I will proceed to describe the same in detail, reference being had for this purpose to the accompanying drawings, wherein- Figure l is a plan view of one of my improved box-blanks. Fig. 2 is a perspective view of a box formed from one of my blanks. Fig. 3 is a transverse sectional view of the blank, taken on the line of Fig. 1.

Referring now to the drawings, the reference-numeral l designates the body of the blank, which in the present instance is shownl as being rectangular in shape; but I wish it understood that I do not confine myself to any particular shape of blank, for obviously the shape and general outline of the blankpmay be varied at will without'departing from the true spirit of the invention, the novel features of which I will now describe.

The corners ofthe blank l are rounded or curved, as at 2, and the sides and ends of the blank are provided with integral Wings or flaps 3 3 and 4c 4, respectively, the body of the blank being scored, cut, or creased along the lines 5 5 and 6 6, where the said ends and side wings or flaps join the said body of the blank, to facilitate the upward bending of said wings or iiaps during the formation of the box. The opposite free ends 7 and S of the side and end wings, respectively, are cut off, so that the maximum length of each Wing will be slightly less than the corresponding Width and length, respectively, of the sides and ends of the body portion of the blank, whereby when the said wings are foldedup in the position shown in Fig. 2 to form the box and the free ends 7 and 8 of said wings are bent around the curved or rounded corners 2 the adjacent edges of the free ends of said wings will just meet and abut against each other to form a .close t, but will not overlap, and this I consider as the important and novel feature of the invention. After the Wings have been folded up in position to form the box they can be retained in such position in any suitable manner, as by metal corner-clips, short strips of paper pasted or glued to the corners, or by a surrounding strip of covering-paper, which `Wi`l-lbe pasted entirely around. the outer circumference of the box, and owing to the fact that a clean flush joint is formed at the rounded corners, no overlapping or crimped parts being present, a smooth unbroken surface is thus provided which adds greatly to the neatness and attractiveness of the box.

As heretofore stated, I do not wish to be understood as limiting myself to any particular form or shape of blank, for obviously the lgeneral shape and configuration of the blank may vary to suit the demands Without departing from the spirit of my invention, the essential feature of which is to provide a box with rounded corners and a continuous smooth outer circumference entirely free from projections or undulations, such as are usually present in boxes having crimped or overlapping portions at the corners.

lfVhat I claim, and desire to secure by Letters Patent, is-

l. A paper-box blank formed from a single sheet, comprising a body portion having rounded corners and integral side and end wings, the maximum length of said Wings being slightly less than the maximum length of the sides and ends respectively of the body portion of the blank, so that When said wings end wings, With lines of scoring or creasing 35 at 'the points of connection between the Wings and body ofthe blank, the maximum length of said Wings being slightly less than the maximum length of the sides and ends respectively of the body portion of the blank, so 4o that when said wings are folded upward into position for the formation of the box, the adjacent edges of said side and end Wings will abut to form a close joint but will not overlap.

In testimony whereof I affix my signature 45 in presence of two witnesses.

HARRY B. SMITH.
