Improvements in the Construction of Folding Boxes made
Cardboard, "Leather-board," and such like Materials.
of
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, 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, &c., whereby great strength is obtained on the sides and angles thereof
by very simple means.
:-
"
My invention is especially applicable to somewhat large sized boxes, and is
represented in the accompanying drawings, in which :-
Fig. 1 is a plan view of a piece of paper or "blank cut to the shape required
to produce my improved box body, and showing the lines on which it is "bent,'
scored or grooved to facilitate the folding thereof.
"
Figs. 2 and 3 are cross sections showing the same in two stages of the folding to
form a box body, and Figs. 4 and 5 are cross sections drawn at right angles to each
other of a finished box body. The lid for such a box body is made in a similar
manner to that of the body.
The broken lines in Figs. 1 to 5 show a slight modification.
Figs. 6 to 10 are similar views to Figs. 1 to 5 showing another slight
modification.
In all the figures like parts are indicated by similar letters of reference.
I will first describe the construction represented at Figs. 1 to 5.
In the "blank" shown at Fig. 1, the central rectangular part a forms the bottom
of the box; b, b-b, b, the longer sides, and c, c¹,-c, c', the shorter sides or ends.
The parts bb have, at each end, a short flap 62, and the parts c' c¹ have, at each
end, a short flap c². The parts bb and cc can be folded in relation to the bottom a
respectively on the lines 63 ; the parts be¹ can be folded in relation to the
parts bc respectively on the lines 6* c*; the flaps 62 can be folded in relation to the
parts on the lines, and the flaps 2 can be folded in relation to the parts c¹ on
the lines c.

In proceeding to fold the "blank" into a box body, I fold the parts b₁ along the
lines over on to the parts b, fold or turn up the said juxtaposed parts bb' on the
line at right angles to the bottom a, see Fig. 2, and fold the flaps 62 inwards on
I then turn or
the lines at right angles to the parts 6 b', as also shown in Fig. 2.
fold the parts c c¹ at one end of the "blank on the line cat right angles to
to the bottom a, see Fig. 3, and fold the flaps e² outwards on the lines
angles to the part c¹; the part c' and parts c³ folded as above, are then folded
inwards on the line e', so that the part c¹ shall be inside the box and enclose the
flaps between it and the part c, whilst the flaps will rest against the end
portions of the parts b¹, see Fig. 4, and can be fixed in position by tucking their
corners through the inclined slots 68 formed in such parts b', see Fig. 5; the
parts c c c at the other end of the box, are treated in a similar manner, thereby
finishing the box body. As shown in the drawings by the full lines, the
parts, care broad enough to extend from top to bottom of the sides of the
box, but, if desired, such parts may be made narrower and terminate at the dotted
lines cor at other desired width; and further, if desired, the inclined slots 66
may be dispensed with and the flaps c² otherwise secured to the parts b b¹, for
instance, by a paper binder passed through holes formed in such parts.

page_text: Also, if desired, the parts bb' may, when folded on to each other, be secured
together by wire staples, paper binders or cement.
In the box body represented at Figs. 6 to 10, the "blank" for formning the same
is shaped and "bent," scored or grooved like that shown in the previous
figures, except that the parts are entirely dispensed with, thereby leaving only a
single thickness of material along the main part of each side, and in such case,
when connecting the parts by tucking a corner of each flap c² into an inclined
slot 6 in the side b, I form such inclined slots at a suitable distance below the upper
edges of the sides b, as shown at Figs. 6 and 10, in order to secure strength, and I
make the flaps c² narrower than the parts c', so that their corners shall be
capable of being tucked through the inclined slots 6*.
By the construction of parts herein described the connection of the sides and
ends of the box is made very strong and rigid as the flaps are held firmly
between the parts c and cannot shift so long as the parts c¹ are held securely in
position by the flaps e² connected with the parts b or b¹.
It will be understood that the terms sides" and "ends" as used above are
convertible the one for the other and instead of being of unequal lengths, such
parts may be of like length the one to the other.
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 :-
CLAIMS.
1. A folding box having a separate body and lid, each of which is formed from
a "blank" of cardboard or the like shaped and "bent," scored or grooved as shown
at Figure 1, and folded so that the sides and ends of the box are each formed of
two parts of the blank folded against each other, and so that each side has at each
of its ends a flap which is held between the two thicknesses of the box ends, and
the parts secured firmly together by means of flaps attached to the inner thickness
of the ends fastened to the box sides, substantially as herein shown and described
with respect to Figs. 1 to 5.
2. A folding box of cardboard or the like having a separate body and lid, each
of which has its sides and ends secured together by flaps attached to the sides held
between two thicknesses of material forming the ends and by flaps attached to the
inner thickness of the ends secured to the sides, substantially as herein shown and
described.
3. A folding box of cardboard or the like constructed substantially as herein
shown and described.
