I, HENRY HARRIS LAKE, of. the Firm of Haseltine, Lake & Co., Patent Agents,
5, Southampton Buildings, in the County of Middlesex, do hereby declare the
ature of this invention and in what manner the same is to be performed, to
e particularly described and ascertained in and by the following statement:-
My invention relates to improvements in folding boxes and the object of my
nvention is to produce a very cheap and simple form of folding box which can
be quickly shaped up for use and which has means by which it can be securely
locked in this position so that it is practically as strong as the ordinary paper
box, although my invention comprises a box which is made without fastening
means of any kind except such means as are formed on the box blank.
My invention consists of a folding box constructed and arranged substan-
tially as shown in the accompanying drawings and described in this specification.
In the drawings, wherein similar figures of reference designate similar parts,
Figure 1 is a perspective view of the box when set up and closed.
Figure 2 is a perspective view of the open box.
Figure 3 is a perspective view of the box when partially folded illustrating
the manner in which the several folds and flaps are placed.
Figure 4 is a sectional plan view of the folding box.
Figure 5 is a plan view of the box blank.
Figure 6 is a perspective view of the open box with a slight modification of
one of its flaps; and
Figure 7 is a broken vertical section illustrating the arrangement of the lock-
ing wings.
The box has a bottom 10, which is rectangular in shape, and this is scored
around the edges, and the blank has at the corners parallel cuts as shown at 11,
11 and 12 thus forming the end pieces 13 and 13" and also the side pieces 14,
these latter being of a width equal to twice the height of the box and being
scored as shown at 15 so as to produce the outer and inner side pieces 16 and 17.
The end pieces 13 and 13ª are also scored at 13b so as to form the short stiffening
0 flaps 18 and 19 which are adapted to fold inward and assist in forming the box
sides as described below. One of the side pieces 16 has also an extension 20
forming a locking strip, which in length is equal to the width of the box and
which when folded into place, as shown best in Figure 4 and as described pre-
sently locks the two side pieces 16 in place and so stiffens the box and prevents
35 the displacement of its parts. The said locking piece is separated from the
part 16 by a scored line 21 to facilitate the folding of the box. I have also cu
in the parts 16 from a point near the score line 15 flaps 22 which are adapted t
folded, as shown clearly in Figure
project laterally into the box when it
and so form a protection to the goods in the box, and the flaps can also be use

page_text: to hold a light cover which may be slipped beneath them, but it will be seen at
once that the box can be used without the flaps 22 if desired, and if a specially
strong box is to be made it is better not to cut the said flaps as the 'sides will
be thereby strengthened.
Extending outward from the end piece 13 and separated therefrom by a
score line 23 is the top or cover 24, which is scored at its outer end as shown
at 25 forming a flap 20, which is preferably, though not necessarily, of a width
corresponding to the height of the box and which is adapted to overlap the front
of the box as shown in Figures 1 and 2, and this flap has at the ends and sepa-
rated from it by a score line 27, locking wings 28 which are adapted to enter
the sides of the box between the side pieces 16 and 17, as shown clearly in
Figures 1 and 7, and so lock the box very securely.
In some cases it is desirable to have a larger flap than the flaps 22 to cover
the goods in the box, and to meet such requirements a flap 30 can be formed
on the outer edge of the end piece 13, and this flap may be wide enough to prac-
tically cover the box as in Figure 6 or it may be cut off at the line 31, in which
latter case it can be used either as a flap or to stiffen the box, and if used as a
stiffener it is folded over against the front side of the box as shown clearly in
Figure 7.
The blank is cut out as described above and, when the box is to be folded for
use, the end pieces 13 and 13ª are bent up perpendicular to the bottom 10, the
flaps 18 and 19 bent inward at right angles to the end pieces, so as to overlap as
shown in Figure 3, the inner side pieces 17 are folded up against the flaps 18
and 19, the side pieces 16 folded over the tops of the flaps 18 and 19
and pushed downward firmly against them thus forming the inner side
walls of the box, and while the said side pieces 16 are being folded in the locking
strip 20 is bent inward parallel with the end wall 13 and pushed downward
against the box bottom, thus forming the inner front wall of the box and at
the same time holding the side pieces 16 against displacement. It will be seen
that this folding of the sides leaves openings at the front ends of the side walls,
which openings are adapted to receive the locking wings of the cover as herein-
after described. It will be observed that this makes the box exceptionally stiff.
The folding as above brings the top or cover 24 to the position shown in Figures 1
and 3 and, when the box is to be closed, this top or cover is folded downward
upon the box and the flap 26 closed over against the front end 13 of the box,
the locking wings 28 being at the same time inserted in the box sides between
the side pieces 17 and flaps 18, so that when the box is closed and the cover
locked down to the position shown in Figure 1 the box has a perfectly smooth
appearance, is firmly locked and is braced by the locking strip 20 and the lock-
ing wings 28 so that it is practically as stift and strong as a solid walled box.
From the foregoing description it will, of course, be understood that the
locking strips 20 can be formed on either of the side pieces 16; that the flap 30
may be made to serve the purpose of the locking strip; that the top flaps 22
may be used or not as desired and that, in any event, the locking wings 28
thoroughly fasten the box. It will also be understood that these locking wings
may be used with other forms of box body having a swinging cover and side
pieces to receive the wings without departing from the principle of the invention.
Having now particularly described and ascertained the nature of said inven-
tion, and in what manner the same is to be performed, as communicated to me
by my foreign correspondents, I declare that what I claim is :-
1. A folding box having a bottom, end pieces connected to opposite sides
thereof, side pieces connected to the two remaining sides of the bottom and
adapted to be folded over upon themselves to form tlie box sides, and a locking
strip connected to the outer portion of one of the side pieces and adapted to fold
into the box at right angles to the side pieces and parallel with and against one
of the end pieces, substantially as described,

page_text: 2. A folding box comprising a bottom, end pieces connected to opposite sides
thereof and provided with end flaps adapted to fold inward at angles to the end
pieces, side pieces connected to the two remaining sides of the bottom, said side
pieces being adapted to fold in the middle and be doubled over the flaps of the
end pieces, and a locking strip connected to one of the side pieces near the outer
part thereof and adapted to fold inward at right angles to the side pieces and lie
parallel with and against one of the end pieces, substantially as described.
3. A folding box comprising a bottom, end pieces connected to opposite edges
thereof and provided with flaps adapted to turn inward at angles to the end
pieces, side pieces connected to the two remaining sides of the bottom and
adapted to be doubled over the aforesaid flaps, of the end pieces, and inturned
flaps cut from the said side pieces and adapted to project laterally into the box,
substantially as described.
4. The combination with the box and the folding end pieces having inwardly
turnable flaps, of the side pieces connected to the bottom and adapted to be

of the side pieces and adapted to fold inward at right angles to the side pieces
and flat against one of the end pieces so as to extend from side to side of the box
between the doubled side pieces, substantially as described.
5. A folding box comprising a bottom, end pieces connected to opposite edges
thereof and provided with inwardly turnable end flaps, side pieces connected to
the two remaining edges of the cover and adapted to be doubled over the flaps of
