Improvements in Blanks for Paper Boxes.
I, HARRY BRIDGMAN SMITH, Manufacturer, of 300, Pacific Street, Brooklyn,
United States of America, do hereby declare the nature of this invention and
in what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement:-
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 cheap and
easily constructed blank for forming paper boxes having ornamental corners,
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 over-lapping parts whatever being
present in the structure which is one of the essential and distinguishing fea-
tures of the invention.
The demand for paper boxes having ornamental corners is very great at the
present time, but as heretofore constructed, it was impossible to obtain such
boxes at a price low enough to enable their general use in connection with
articles sold at a nominal price. Furthermore, boxes now upon the market,
having ornamental corners so far as I am aware either have crimps or folds at
the corners, or are formed with over-lapping portions or edges, which render
the corners uneven cumbersome, or bulky and otherwise detract generally 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
cut away, bevelled or rounded and provided with integral side and end wings or
Haps which have the opposite ends thereof cut off, or removed to such a degree or
extent as that when folded up to form the box the adjacent edges of said wings
or flaps will abut each other to form a close fit, but will not over-lap one upon
the other, thus producing a smooth and continuous unbroken surface around
the outer circumference of the box.
In order to enable others to construct box blanks 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 drawing, wherein:
Figure 1 is a plan view of one of my improved box blanks for making a ▸
round cornered box.
Figure 2 is a perspective view of a box formed from the blank shown in
Figure 1.
Figure 3 is a transverse sectional view of the blank taken on the line -
of Figure 1.
Figure 4 is a plan view of a modified form of blank.
Figure 5 is a perspective view of one corner of a box formed from the
blank shown in Figure 4.
Figure 6 is a plan view of one corner of a further modified form of blank,

page_text: Figure 7 is a perspective view of one corner of a box formed from the blank
shown in Figure 6.
Figure 8 is a plan view of a blank similar to that shown in Figure 4, but
illustrating a modified manner of forming the side and end wings or flaps, and
Figure 9 is a perspective view of one corner of a box formed from the blank
shown in Figure 8.
Referring now to the drawings, Figures 1, 2 and 3 the reference numeral I
designates the body of the blank, which in the present instance is shown 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 blank may be varied at will without departing from the true spirit of
the invention, the novel features of which I will now describe.
The corners of the blank 1, as shown on Sheet 1 of the drawings, 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 4, 4, respectively, the body of the blank being scored,
cut or creased along the lines 5, 5 and 6 6, where the said end and side wings
or flaps join the said body of the blank, to facilitate the upward bending of said
wings or flaps during the formation of the box.
The opposite free ends 7 and 8 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 folded up in the posi-
tion shown in Figure 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 each other to form a close fit, but
will not over-lap; and this I consider an important and characteristic 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 cover-
ing paper which will be 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 over-lapping or crimped parts being present, a smooth, unbroken surface is
thus provided which adds greatly to the neatness and attractiveness of the box.
Upon Sheet 2, of the drawings, I have shown several modified forms of my
invention in which the corners of the blank are cut away, chamfered, or bevelled
at an angle to the sides and ends of the box to form boxes having correspond-
ing cut-away or angular corners.
Referring to Figures 4 and 5 the corners of the blank 1, are chamfered,
bevelled or cut away at an angle to the sides and ends of that portion designed
to form the bottom of the box, as indicated at 2", and the sides and ends of the
blank are provided with integral flaps or wings 3, 3, and 4, 4, respectively, as
in the form of blank shown in Figures 1, 2 and 3, the body of the blank being
scored, cut or creased along the lines 5, 5, and 6, 6, where the said end and
side flaps or wings join the said body of the blank to facilitate the folding or
upward bending of said flaps or wings during the formation of the box.
The opposite free ends 7 and 8, of the side and end flaps respectively, are cut
off in such manner that the maximum length of each flap 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 flaps are folded up into
position as shown in Figure 5, to form the box, and the free ends 7 and 8. of
said flaps are bent over the chamfered or bevelled corners 2, the adjacent edges
of the free ends of said flaps will just meet and abut each other as in the case
with the round cornered box shown in Figures 1, 2 and 3, but will not overlap
and this constitutes an important and prominent characteristic of each form of
box herein shown and described.
To ensure the ends of the flaps being bent so as to accurately conform to
the

page_text: chamfered or bevelled corners, and to facilitate 'such bending, the said flaps are
scored, cut or creased transversely on the lines 9, 9, and 10, 10, such scored, cut
or creased lines extending from the outer edges of the flap to the points where
the free ends of the latter join the body of the blank. After the wings have
been folded up into position to form the box they can be secured together in
any suitable manner, as by metal corner clips, or paper strips, all as set forth
herein before with reference to the round cornered box shown in Figures 1, 2
and
In Figures 6 and 7, of the drawings, I have illustrated a further modified
form of blank, the corners of which instead of being chamfered or bevelled off
on a straight line as in Figure 4, are each chamfered or cut away at a compound
angle, that is to say, whilst each corner is cut away at an angle to the sides and
ends of the body of the blank, instead of being cut away on a straight line is
cut on two straight lines 11, 11, formed at an obtuse angle to one another, the
apex of which lies equidistant between the points where the ends of the flaps
and 4, join the body of the blank. Otherwise the construction of the blank is
the same in all respects to those before described.
In Figures 8 and 9, I have illustrated a still further modified form of blank
which is formed in precisely the same manner as the blank shown in Figure 4,
excepting that instead of cutting off the opposite ends of the side and end
flaps 3 and 4", in such manner that each will project beyond the points inter-
sected by the chamfered or bevelled corners, only one end of each flap shall
project in such manner, as clearly indicated at 7", and S", the opposite end 12,
being cut off at the point where the flap is intersected by the chamfered or
bevelled corner, the relative proportions of the flaps and body of the blank
nevertheless being still retained in such manner that the maximum length of
the side and end Haps shall be less than the corresponding maximum length of
the body of the blank, whereby when the flaps are folded up into position to
form the box the free ends 7 and 8 will conform to the chamfered or bevelled
corners of the blank and their vertical edges will just meet and abut the corre-
sponding edge 12, of the adjacent flaps, in the same manner and for the purpose
heretofore described.
In each of the forms of blanks shown on Sheet Two of the drawings the flaps
are scored, cut or creased transversely as shown to facilitate folding the free
ends of the flaps and cause them to accurately conform to the chamfered or
bevelled corners of the blank, such lines of scoring in each instance being
formed at the points where the ends of the chamfered or bevelled corners join
the flaps, but in the round cornered box shown in Figures 1, 2 and 3 no such
scoring is required.
As heretofore stated I do not wish to be understood as limiting myself to any
particular form or shape of blank, for obviously the general shape and con-
figuration 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 cut-away or ornamental corners and a continuous smooth outer circum-
ference entirely free from projections or undulations such as are usually present
in boxes having crimped or over-lapping portions at the corners.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is:
1. A paper box blank formed from a single sheet, comprising a body portion
having cut-away corners and integral side and endwings, 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
are folded up into position for the formation of the box, the adjacent edges of
the said side and end wings will abut but not over-lap, substantially as described.
2. A paper box blank formed from a single sheet, comprising a body portion

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
are folded up into position for the formation of the box, the adjacent edges of
said side and end wings will abut but not over-lap, substantially as described.
3. A paper box blank formed from a single sheet, comprising a rectangular
body portion having rounded corners and integral side and end wings, with
lines of scoring or creasing at the points of connection between the wings and
body of the 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 that when said wings are folded upward into position for the for-
mation of the box, the adjacent edges of said side and end wings will abut to
form a close joint but will not over-lap.
4. A paper box blank formed from a single sheet, comprising a body portion
having chamfered or bevelled corners and integral side and end flaps, the
maximum length of said flaps being slightly less than the maximum length of
the sides and ends respectively of the body portion of the blank, whereby when
said flaps are folded up into position for the formation of the box the adjacent
edges of said side and end Haps will abut but not over-lap, substantially as
described.
5. A paper box blank formed from a single sheet, comprising a body portion
having chamfered or bevelled corners and integral side and end flaps, said flaps
being scored or creased transversely at the points intersected by the ends of
the chamfered or bevelled corners, the maximum length of said flaps being
slightly less than the maximum length of the sides and ends respectively of
the body portion of the blank, whereby when said flaps are folded up into posi-
tion to form the box the adjacent edges of said side and end flaps will abut to
form a close joint but will not over-lap, substantially as described.
6. A box blank formed from a single sheet substantially as described and
illustrated in Figure 1 or in Figure 4, or in Figure 6, or in Figure 8 of the
accompanying drawings.
