page_text: Improvements in Folding Boxes made of Cardboard, Leatherboard and
the like.
I, REGINALD HARRY FILMER, of 17 Little Sutton Street, Clerkenwell, in the
County of London, Box Manufacturer, do hereby declare the nature of this in-
vention to be as follows:-
My invention applies to that class of box body which has its four sides perma-
nently connected together and capable of folding on the lines connecting them
with the bottom, two opposite sides of said box being also creased or grooved and
folded on lines of 45° extending from the bottom corners of said sides to the upper
edges of the latter. Boxes of this character have heretofore been made only of
small dimensions and of comparatively thin material for use as egg boxes, and they
have depended for their stiffness on the interior cardboard divisions used there-
with. Such boxes have also had their lids permanently connected with the bodies
thereof.
Now according to my present invention I am enabled to make a large stiff box
body having the sides permanently connected together which whilst capable of
being readily folded flat on to the bottom for storage like the boxes hereinbefore
referred to are also provided with strengthening or stiffening flaps on the two
doubly folded sides, which flaps whilst capable of folding in like manner to their
carrying sides greatly stiffen said sides when the box body is set up for use and said
flaps are folded over the box body.
For this purpose I cut the material to form the two doubly folded sides wider
than the two other sides and crease or groove them on the lines intended for the
height of the box body I also continue the diagonal creases or grooves from the
bottom corners of said sides not only across the latter but also in the same direction
across the strengthening or stiffening flaps.

I, REGINALD HARRY FILMER, of 17, Little Sutton Street, Clerkenwell, in the
County of London, Box Manufacturer, do hereby declare the nature of this in-
vention and in what manner the same is to be performed to be particularly
described and ascertained in and by the following statement:-
My invention applies to that class of box body which has its four sides perma-
nently connected together and capable of folding on the lines connecting them
with the bottom, two opposite sides of said box being also creased or grooved and
folded on lines of 45° extending from the bottom corners of said sides to the upper
edges of the latter. Boxes of this character have heretofore been made only of
small dimensions and of comparatively thin material for use as egg boxes, and they
have depended for their stiffness on the interior cardboard divisions used there-
with. Such boxes have also had their lids permanently connected with the bodies
thereof.
Now accoding to my present invention I am enabled to make a large stiff box.
body having the sides permanently connected together which whilst capable of
being readily folded flat on to the bottom ior storage like the boxes hereinbefore
referred to are also provided with strengthening or stiffening flaps on the two
doubly folded sides, which flaps whilst capable of folding in like manner to their
carrying sides greatly stiffen said sides when the box body is set up for use and said
flaps are folded over the box body.
My invention is illustrated in the accompanying drawings in which Fig. 1 is
a plan view of the material to form the box body opened out flat and showing the
lines on which it is creased or grooved to enable it to be folded into the form
required. Figs. 2 and 3 are respectively a plan and side view of the box body
erected for use with the additional or strengthening flaps folded over and ready
to receive the lid. Figs. 4 and 5 are two side views drawn at right angles with each
other showing the box body erected for filling but with the additional or strengthen-
ing flaps in a vertical position and Figs. 6 and 7 are respectively a plan and an
edge view of an empty box body folded flat for storage or transport.
In carrying my invention into effect I cut the material to form the box body to
the shape shown in Fig. 1 and I crease or groove the same on the lines 6 forming
the boundary of the bottom a and junction of the sides c and d therewith. The
sides c have short triangular flaps el at each end thereof and the material is creased
on the lines e bounding said sides and upon which the flaps c' are folded.
The sides d are creased or grooved on the diagonal lines f and the triangular
flaps care pasted, wire stitched or otherwise secured as shown at d Figs. 3 and 4,
to the triangular parts of said sides d.
According to my present invention I cut the material to form the two doubly
folded sides d wider than the two other sides c so as to form two stiffening or
strengthening flaps 7 and I crease or groove them on the lines h intended for the
height of the box body, I also continue the diagonal creases or grooves f from
the bottom corners of said sides d, not only across the latter as heretofore, but also
in the same direction across the strengthening or stiffening flaps g thereby enabling
the said flaps g to hold on the lines f in like manner to their carrying sides d.
Having now particularly described and ascertained the nature of my said in-
vention and in what manner the same is to be performed I declare that what I
claim is :-
1. A box body of the character herein described provided with folding stransthor

page_text: ing or stiffening flaps connected to two of its sides, such flaps and their carrying
sides being creased or grooved diagonally as herein described and for the purpose
stated.
2. The combination with a box body of the character herein shown and described
of a stiffening or strengthening flap attached to each of two opposite sides thereof
and having diagonal creases or grooves in continuation of those of their carrying
sides, as herein set forth and for the purpose stated.
