Improvements in the Manufacture of Paper or Pasteboard Boxes.
I, HENRY HARRIS LAKE, of the Firm of Haseltine, Lake & Co., Patent
Agents, 45 Southampton Buildings, in the County of Middlesex, 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 invention relates to the construction of knock down boxes of paper or paste
board, and has for its object to provide a box of this description which shall be at
once exceedingly strong and stiff, have a particularly finished appearance, and be
easy of construction.
The nature of my improvements will be best understood as described in connection
with the drawings in which they are illustrated, and in which,
Figure 1 represents the blank formed with laps and creases adapted for the
construction of my new box in what I consider its best and most perfect form.
Figure 2 is a perspective view of the blank representing the first folding
operation.
Figure 3 showing the second folding operation;
Figure 4 the third folding operation;
Figure 5 the fourth or completing fold;
Figure 6 is a longitudinal section through the completed box;
Figure 7 a transverse section;
Figure 8 a perspective view of one corner of the inside of the box before the
false or inner bottom is secured in place.
Figure 9 is a plan view of a somewhat modified blank provided with laps and
creases adapted to the manufacture of a bex having the leading features which
characterize my present invention.
Figure 10 shows the box in process of manufacture.

Figure 12, a cross-section, and
Figure 13 a longitudinal section of the modified construction.
A in all of the figures indicates the bottom of the box, B B the laps forming the
sides or side walls, and EE the laps forming the ends or end walls C and C indicate
laps extending from and formed integral with the laps B and B and adapted to fold
down on the inside of the box against the side walls or laps B, each of the laps C
being by my new construction provided with terminal laps D and D which are
adapted to fold down against the bottom A of the box. I also provide the end
laps or walls E with laps F formed in continuation thereof and adapted to fold
down against the laps or end walls E on the inside of the box, and preferably
I provide each lap F with a terminal lap as G or H, which is adapted to fold down
upon and lie along the bottom A of the box. B B' etc., indicate Jateral
prolongations of the laps B which, as is usual in boxes of this kind, are folded
at right angles to the laps B and are enclosed between laps E and F. H and
H¹ indicate pieces of paste board preferably formed integral with the blank and
adapted to serve as an inner or false bottom to the box, serving not only to

page_text: strengthen the bottom, but also to hold the inwardly folded laps C C and F Fin
proper position against the outer walls of the box.
Preferably where the short horizontally lying laps G and D would, if extended
to the full width of the sides and end pieces, lap upon each other, I cut away the
corners as indicated at g g to avoid this lapping, and so that both the laps D and G
may lie flat upon the bottom A of the end and I will here mention that while
I greatly prefer to provide the end laps F with the horizontally lying extensions,
such extensions may, nevertheless, be dispensed with without departure from the
broad features of my invention which, however, in all cases involves the use of the
horizontally lying extensions of the side laps CC because these side laps being of
much greater length than the end laps require for properly holding them in place
the brace which is afforded by the horizontally lying extensions.
In my preferred form of construction I make the inner or false bottom piece H
as a prolongation of one of the side laps F as indicated in Figs. 1 to 8, though the
bottom piece may with many of the advantages of my new construction be formed
as a prolongation of one of the side laps C indicated in Figs. 9 to 13.
Among the particular merits of my preferred form of construction indicated in
Figs. 1 to 8 is the ease and simplicity of the operation by which the properly
prepared blank is formed into a box. This is illustrated in the drawings. The
first folding operation being to turn the laps C and D inward around the crease
line 1, bringing the blank to the form indicated in Fig. 2. The side pieces B C
are then bent upward around the crease lines 2 until they stand perpendicular to
the bottom A, this manipulation also bending at right angles to the lap C and
terminals laps D which, of course are bent on the crease lines 3. The next
folding consists in bending in the terminal laps B' B at the left end N of the
blank as represented until they stand at right angles with the laps C and the
bottom A as indicated in dotted at Fig. 3. The end piece E is the bent up at
right angles to the bottom on the crease line 5, the lap F pressed in and down over
the terminals B' B' and the terminal lap G at the same time pressed down upon
the bottoin A of the box, bending on the crease line 7 with the result indicated in
Fig. 4. The end of the box thus completed will hold its own shape, enabling the
operator to give his undivided attention to the holding of the other or right hand
end of the box which is accomplished in precisely the same way, except that
instead of the short lap G is the long lap or bottom piece H which is pressed down
upon the bottom of the box covering the laps D D and G and forming a perfectly
smooth bottom at the same time that it locks the inwardly bent laps securely in
position..
In the manipulation of the modified blank shown in Fig. 9 what I may call the
front or lower series of laps projecting from the bottom piece A is most conveniently
folded in precisely the same way as the similar laps in the blank of Fig. 1. The
upper side pieces B, however, with its terminal laps is folded up around the creased
line 2, as indicated in Fig. 10, the terminal laps B₁ are then folded into proper
position, and the end laps F F and G folded over them as in the case of the other
blank, the final folds making this modification of my box consist in pressing the
laps C down around the crease line 1 until it lies against the inside of B, and then,
or at the same time, pushing the termiual lap or bottom piece H' down upon the
inside of the box and so as to cover the terminal laps lying upon the bottom of the
box and abutting against the inner walls thereof.
The box formed in accordance with my invention presents a smooth and finished
appearance both inside and outside, and at the same time all of its parts are
braced and buttressed in such a way as to give the box great strength and
rigidity.
Of course it will be understood that by the term box I have reference as well to
box covers as to the box proper.
Some of the advantages of my invention are present even if the false bottom is
not formed as an integral part of the blank but is simply inserted after the box has

page_text: been erected and so as to overlic the terminal flaps and press the inner side laps
against the outer laps.
Having now particularly described and ascertained the nature of the said inven-
tion, and in what manner the same is to be performed, as communicated to me by
my foreign correspondent, I declare that what I claim is,
1. A knock down box having end and side walls, said side walls having laterally
extending flaps B' and end and side laps adapted to fold down inside of the walls
of the box, said side laps having lap extensions adapted to fold down upon the box
bottom and a false or inner bottom adapted to fit the inner side of the box bottom
and hold the inner walls of the box against the outer walls thereof.
2. A knock down box baving end and side walls, said side walls having laterally
extending flaps B' and adapted to fold down inside of the walls of the box, said
laps all having lap extensions adapted to fold down upon the box bottom and a false
or inner bottom adapted to fit the inner sides of the box bottom and hold the inner
walls of the box against the outer walls thereof.
3. A knock down box having end and side walls, said side walls having laterally
extending flaps B and adapted to fold down inside the outer walls of the box, said
side laps both having lap extensions adapted to fold down against the box bottom
and a false bottom formed of an extension of one of the inwardly folding laps and
of the breadth of the box bottom whereby it holds the inner walls or laps against the
outer walls of the box.
4. A knock down box having end and side walls, said side walls having laterally
extending flaps B₁ and end and side laps adapted to fold down inside the outer
walls of the box, said laps all having lap extensions adapted to fold down against
the box bottom and a false bottom formed of an extension of one of the inwardly
folding laps and of the area of the inside of the box whereby it abuts against and
holds the inner laps against the box walls.
5. A knock down box having end and side walls, said side walls having laterally
extending flaps B' and end and side laps adapted to fold down inside the outer
walls of the box, said laps both having lap extensions adapted to fold down against
the box bottom and one end lap having a lap extension of the area of the inside of the
box adapted to fold down upon the box bottom and abutted against the inner laps
so as to hold them against the outer box walls.
6. A knock down box having end and side walls, said side walls having laterally
extending flaps B', said end and side laps adapted to fold down inside the outer
walls of the box, said side laps and one end lap having short extensions adapted to
fold down upon the box bottom, and the other end lap having an extension of the
area of the box bottom adapted to fold down upon the box bottom and abut against
the inner laps so as to hold them against the outer box walls.
7. A knock down box having end and side walls, said side walls having laterally
extending flaps B', and end and side laps adapted to fold down inside the outer
walls of the box, said side laps and one end lap having short extensions adapted to
fold down upon the box botton, the ends of the end lap extension being cut away
so as not to lap on the extensions of the side laps, and the other end lap having an
extension adapted to fold down and form a false or inner bottom for the box.
