-Improvements-in-the-Construction-of-Folding-Boxes Made of
Cardboard, Leatherboard, and such like Materials.
I, REGINALD HARRY FILMER, of 17 Little Sutton Street, Clerkenwell, in the
County of London, Box Manufacturer, do hereby declare the nature of this
invention to be as follows:-
The invention has for its object an improved construction of folding box of
cardboard, leatherboard or such like material, in which the body and lid of the
box, as also the parts for securing the lid and other parts in positiou, are all
comprised in a single piece of material.
The blank to form the box is scored, bent or grooved on lines bounding the.
bottom, sides, ends and lid of the box, to enable it to be readily folded on such
lines; the ends of the box body are formed of overlapping flaps forming end
continuations of the sides, and one of such flaps at each end of the box has
extending therefrom a locking and holding flap, which has one or two locking
notches, so that when the box is folded into form, these locking and holding flaps
may be placed across the lid and have their notches interlocked, thereby forming a
lock to hold the lid in position and at the same time form a support to the ends
and a handle by which the box can be carried. The end flaps are secured in
position as follows. At the ends of the box bottom are flaps which, on the folding
line, are of the full width of the box end, but which narrow down to the width
apart of two supplemental locking flaps formed thereon and scored, bent or grooved,
on the folding lines. These supplemental locking flaps are formed with locking
notches; the overlapping end flaps are slotted at the required positions to enable
the supplemental locking flaps to be passed therethrough, and these latter flaps,
after having been passed through such slots, have their notches interlocked,
thereby securing the parts forming the box ends firmly together. The lid has
shallow end flaps which descend into the body of the box and rest upon the
supplemental locking flaps of the ends. The lid is formed of two overlapping parts
which may be of equal width, but I prefer that one of them, as also its end Haps,
be of width to extend fully across the width of the box, so that said end flaps may
bear end wise against the inside of the box sides and thereby afford support
against crushing; the other part of the lid may in this case be narrow and without
end flaps.
When the lid is formed of two overlapping parts, each of width less than that
of the box body, each of such parts is provided with shallow end flaps, and in such
case the locking and holding flaps, being shorter than in the other case, can each
have only one locking notch.

Cardboard, Leatherboard, and such like Materials.
I, REGINALD HARRY FILMER, of 17 to 20 Little Sutton Street, Clerkenwell,
in the County of London, Box Manufacturer, 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 :-
The invention has for its object an improved construction of folding box of
cardboard, leatherboard or such like material, in which the body, lid and handle of
the box, as also the parts for securing the sides, lid and handle in position, may be
all comprised in a single piece of material.
•
My invention is illustrated in the accompanying drawings, in which
Fig. 1 is a plan of the blank shaped and scored, bent or grooved, according
to my invention, to form a box, lid, fastening and holding means from a single piece
of material.
Fig. 2 is a plan and Fig. 3 is a cross section of the same partially folded
into shape.
Fig. 4 is a vertical cross section, Fig. 5 is a vertical longitudinal section on
line 5-5, Fig. 4, and Fig. 6 is a perspective view of the complete box, showing
the lid fastening and holding means secured for use.
The blank to form the box is cut to the shape required and scored, bent or
grooved, on lines a a¹ bbc bounding the bottom d, sides e, ends and lid 9 of
the box, to enable it to be readily folded on such lines; the ends of the box
body are formed of overlapping flaps forming end continuations of the sides e,
and one of such flaps fat each end of the box has extending therefrom a locking
and holding flap h, which has one or two locking notches h¹, so that when the box
is folded into form these locking and holding flaps h, which are bent, scored or
grooved, at their junction 2 with the end flaps f, may be placed across the lid g
and have their notches interlocked, thereby forming a lock to hold the lid g in
position and at the same time form a support to the ends and a handle by which
the box can be carried.
The end flaps are secured in position as follows. At the ends of the box
bottom are flaps i, which, on the folding lines a¹, are of the full width of the box
end, but which narrow down to the width apart of two supplemental locking flaps j
formed thereon and scored, bent or grooved, on the folding lines k, which, for
convenience of manufacture, run completely across the blank. These supplemental
locking flaps are formed with locking notches j; the overlapping end flaps fare
slotted at the required positions f¹ to enable the supplemental locking flaps j to be
passed therethrough, and these latter flaps j, after having been passed through such
slots and been turned towards each other by bending on the lines k, have
their notches interlocked, thereby securing the parts f forming the box ends
firmly together.
The lid flap g has end flaps 92 which descend into the body of the box and may
be made wide enough to rest upon the supplemental locking flaps ; of the ends i.
The lid is formed of two overlapping parts gg', which may be of equal width, but
I prefer that one of them, g, as also its end flaps g2, be, as shown in the drawings,
of width to extend fully across the width of the box, so that said end flaps g² may
bear end wise against the inside of the box sides e and thereby afford support
against crushing in that direction; the other part, 93, of the lid may in this case
be narrow and without end flaps as shown. When the lid is formed of two over-
lapping parts 99', each of width less than that of the box body, each of such parts
is provided with end flaps 9, and in such case the locking and holding flaps h,

page_text: being necessarily shorter than in the other case, can each have only one locking
notch, and in such case, in order to increase the facility of manufacture, one of
the locking and holding flaps h would be formed on one end flap f adjacent to the
lid flap 9 and the other on the end flap fat the opposite corner on the other side
of the blank, adjacent to the lid flap g. When the flaps are deeper than shown
in the drawings I find it convenient to round off or remove their corners, so as to
enable them to be readily inserted into the box.
The following is the method of folding the blank into a box and lid and of
fastening down the lid and providing a handle for carrying the same. The sides e
are first folded on the lines a so as to stand vertically in relation to the bottom d,
the end flaps are then folded on the lines b¹ so as to stand across and form the
ends of the box as shown at Figs. 2 and 3, the flaps are next folded on the lines a¹¯
and the supplemental locking flaps ; are folded on the lines k and passed through
the slots, then folded towards each other, after which such flaps have their
locking notches interlocked on the inner sides of the ends. The end flaps 92
of the lid are then folded on the lines c and the flaps g g' forming the lid are folded
on the lines bb over the top of the box, the flap 9 extends over the flap g' and the
end flaps 9 pass inside the end flaps fand, according to the example shown in the
drawings, rest upon the locking flaps j and fit at their ends against the sides e of
the box, thereby affording support to the sides and lid of the box against a crushing
pressure. The locking and holding flaps are next folded on the lines over the
top of the box and their notches / interlocked, thereby securing the lid and at the
same time forming a convenient Landle for carrying the box.
Other means of locking the flaps j and h may be adopted and, if desired, the
body of a box may be made as above described and used independently of a lid, or
a lid for the same might be formed in any suitable manner.
The special advantages resulting from my improved construction of folding box
in comparison with those hitherto in use, are complete security of the fastening
means, increased strength against deformation from without as well as from within,.
and convenience for carrying the box, which is moreover of a neater appearance
and without any openings through which dust or the like can enter, and being made
all in a single piece, there is no fear of any of the parts being absent at the moment
wben required for use.
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 I
claim is :-
1. A folding box made of a single piece of cardboard, leatherboard or such like
material, scored, bent or grooved, on the lines bounding the bottom d, sides e and
end flaps forming end continuations of the sides e and having locking slots f
therein, locking flaps i at the ends of the bottom d, supplemental locking flaps j at
the upper ends of the flaps i which are passed through the slots f', then bent.
towards each other and interlocked to secure the ends, a lid formed of flaps g g²,
one or both of which is provided with end flaps 92, and a locking and holding
flap on each of two end flaps which are folded over the lid and interlocked
to form a combined fastening and holding means, substantially as herein shown and
described.
"
2. A folding box body made of a single piece of cardboard, leatherboard or such
like material, scored, bent or grooved, on the lines bounding the bottom d, sides e
and end flaps f forming end continuations of the sides e and having locking slots f1.
therein, locking flaps i at the ends of the bottom d, supplemental locking flaps j at.
the upper ends of the flaps i which are passed through the slots f, then bent.
towards each other and interlocked to secure the ends and thereby hold the body
of the box securely together, substantially as herein showu and described.
3. A folding box made of a single piece of cardboard, leatherboard or such like.
material, scored, bent or grooved, on the lines bounding the bottom, sides
and ends, and having locking flaps attached to the ends folded over the lid and.
