Improvements in Folding Boxes.
I, MICHAEL JACOBY of Grun Street 17/18 Berlin, C. in the Empire of Germany,
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:-
This invention relates to improvements in card board or other folding boxes
in which the box is formed by folding from a single piece of card-board cut in a
suitable manner, and its object is to produce boxes of polygonal form where the
cut edges of the box to be joined are uneven in number.
The invention mainly consists in the arrangement of grooves in the card board
forming the vertical sides of the box and in the means for closing or folding these
sides when the boxes are not in use to economize space.
On the accompanying drawing a three sided folding box is shewn by way of
example,
Figures 1 & 2 being respectively a front elevation and plan of the box
complete and
Figure 3 a view of a folded form.
The case or box is made out of one piece in such a way that at corresponding
distances on the cardboard, vertical grooves a, b, c, are provided and the cardboard
is bent round as shown in Figure 2 and brought together at the third groove c,
so as to be fastened there with paste, pin fastenings or such like. By constructing
the boxes as hereinbefore described they can be folded together which is not only
necessary for storing the empty boxes; but also for rapid pin or clamp fastening
of the box edges with machines when required for use, while one of the vertical
sides is provided with a groove d in its middle so that the box can be folded together
into two thicknesses of cardboard, the side b, c, lying upon the side b, a, while the
side a, c, is doubled upon the groove d, the whole lying flat in one plane as shown
at Figure 3.
The closing of the ends of the box is effected in a simple but extremely suitable
way, each of the vertical sides being provided with a triangular flap, top and bottom,
two of which a', 6', preferably form equalateral triangles, whilst the third c¹ is pro-
vided with a flap e which is to be inserted in the incision f in one or in both the
other flaps. This closing forms the ends of the cardboard boxes or cases.
For larger sizes the box can be constructed of several parts of cardboard whilst
clamps, pins, or glued bands maintain in their place the several edges.
The box may be produced' out of any other material such as metal, celluloid etc.
Having now particularly described and ascertained the nature of my said
Invention, and in what manner the same is to be performed, I declare that what
I claim is:-
1. In folding boxes triangular in plan of cardboard or other material and made
from a single piece, the provision of grooves at each fold and a groove in the centre
of one side as a means for conveniently constructing the box for use, or packing it

page_text: for storage substantially as hereinbefore described with reference to the accom-
panying drawings.
2. In folding boxes triangular in plan of cardboard or other material and made
from a single piece, the construction of the box ends and the fastening of the same
by means of a flap c inserted in an incision f in one or both of the end pieces
substantially as hereinbefore described with reference to the accompanying
drawings.
