Improvements in Paper Boxes.
1, ROBERT PITFIELD BROWN, of 3412 North Nineteenth Street, in the City
of Philadelphia, in the State of Pennsylvania, one of the United States of America,
Manufacturer, do hereby declare the nature of my invention and in what manner
the same is to be performed, to be particularly described and ascertained in and
by the following statement :-
My invention relates to knock down paper or cardboard boxes, and has for its.
main object to provide a box which, when set up, will be very firm and stiff.
My invention is best explained in connection with the accompanying drawings,
in which,
Figure 1 is a view of the blank, which, when set up, forms the box.
Figure 2 is a perspective view of the box partly set up; a portion of one side
being torn away to show the mode of fastening the ends.
Figure 3 is a transverse vertical section of the box when completely set up.
Figure 4 is a detail view of a modification showing how the locking flap at
the extremity of the end pieces may be dispensed with; and
Figure 5 shows a completed box with one form of cover therefor.
B is the blank from which the improved box is constructed, and consists of a
bottom piece C, and side and end flaps A A D D. The bottom piece C is provided
with tongues c c formed by cuts e² ²; these tongues are formed near the ends of
the bottom piece and are designed to lock the end pieces, as will be explained.
The side flaps A A have wings a a, extending from each extremity, as shown.
which wings are adapted to form part of the ends of the box. The end flaps D D
consist, as shown in Figures 1, 2 and 3, of portions dd, d¹ d', and d² d²,
score marks eel being preferably provided to cause the material to bend in the
proper places. The parts d d are adapted to fold up outside of the wings a a,
when these are folded, substantially as shown in Figure 2, the parts d' d' fold
inside of the wings a a and the locking flaps d² d' are then caught under
the tongues cc, locking the whole end in place. It will be noted that, as the
wings a a are folded under the end flaps DD the sides A A are held in position
thereby, and also that there are three thicknesses of material at the ends, thus
making a very stiff box; one of the thicknesses of the material, namely, the
flaps did' fits inside the box and further stiffens it. In some cases it may not be
necessary to provide the tongues c c, but simply bend down the flaps d' d' inside
the box. I prefer, however, to provide these tongues c c, even if the locking
flaps d d are omitted, since, as seen in Figure 4, if the tongues c c are arranged at
the extremities of the bottom C, they will engage with and hold in place the
partsd of the end flaps in the manner shown in Figure 4. Suitable score marks
such as are indicated at a² c¹ may, of course, be provided when necessary.

page_text: I also contemplate, in some cases, to form flaps G integral with the sides A A, as
shown in dotted lines in Figure 1; these, when folded down as shown in Figure 5,
not only serve to give the box an ornamental appearance, but also serve to prevent
small articles, such, for instance, as matches, if the boxes are used to hold these,
from readily falling out, taking the place of the independent piece of paper or
cardboard often used for that purpose.
In Figure 5 I have shown the completed box provided with a slide cover F; it
will, of course, be understood that any suitable cover can be employed.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what
.claim is
1. A knock down box having a bottom C with tongues e c formed therein, sides A
provided with wings a a extending from both extremities of said sides, and adapted
to form part of the ends of the box, and end flaps D consisting of parts dd
adapted when the box is set up, to fold outside of the wings a a and parts d¹ d¹
adapted to fold inside of the wings a a and be held in position by the tongues cc,
all substantially as specified.
2. A knock down box having a bottom C, sides A provided with wings a a
extending from both extremities of said sides and adapted to form part of the ends
of the box, end flaps D consisting of parts d d adapted when the box is set up to
fold outside of the wings a a, parts d' d' adapted to fold inside of the wings a a and
locking flaps d d and a suitable lock adapted to engage with the locking flaps d² d²
and hold the ends in place.
3. A knock down box having a bottom C with tongues c c formed therein,
sides A provided with wings a a extending from both extremities of said sides
and adapted to form part of the ends of the box and end flaps D consisting of
parts d d adapted, when the box is set up, to fold outside of the wings a a and
parts d' d' adapted to fold inside of the wings a a and flaps d2 d2 adapted to
extend under the tongues c c, all substantially as specified, and so that firm and
stiff ends will be formed from the folds d d and wings a a.
4. A knock down paper box having sides A provided with flaps G and with
wings a extending from both extremities thereof and adapted to form part of
the ends of the box, a bottom C having tongues c c and ends D formed of
parts d d d said parts d adapted to fold outside, and the parts d' inside of the
wings a a and so form the box ends and the parts d² ² adapted to fit under the
tongues c c all substantially as specified, and so that a firm and stiff box will be
provided.
