Improvements in Folding Boxes.
I, LEOPOLD MAYER, of Stuttgart, Reuchlinstrasse No. 20, in the Kingdom
of Würtemberg, Merchant, do hereby declare the nature of my invention for
IMPROVEMENTS IN FOLDING BOXES, and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement, reference being had to the accompanying sheet of drawings and to
the letters and figures marked thereon, that is to say:
The object of the present invention is to provide a box which in consequence of
its simplicity and cheapness is well suited for packing goods of small value, which
has been hitherto for the most part impossible owing to the expense incurred by
using boxes even of the most common sort. By a modification of the invention,
hereinafter described I can provide a perfectly air tight, collapsible box, par-
ticularly adapted for packing aromatic and mealy substances. This box may be
exported very conveniently and cheaply in a collapsed or folded condition, then
filled with tea etc. and imported. This article offers many advantages over others
of similar kind of which the principal are its efficiency cheapness and simplicity.
Figs. 1, 2 and 3 show a box made of one piece of cardboard, whereby the opposite
corners A are folded over and glued together, and the opposite corners B are
turned up towards A in such manner that the corners D and lid and bottom of the
box are formed. The box is now closed by pushing the points & under the corner-
edges a.
Fig. 4 is a modification showing a box made of two pieces of cardboard. The
difference between this box and the one hereinbefore described is, that the upper
side A of the box is made double (as shewn at J) so that the latter is considerably
stiffened and a pocket or slip formed at F for the reception of the points b, which
may be inserted in the same thus forming a more secure fastening.
Fig. 5 shows a second modification in which the cover H with projecting edges h
is added to the ends B, by which double corner-folds h' and triple corner-folds h*
are formed.
To close the box, the points bare inserted in the slit E, and thus the box receives
the same tight fastening as that in the modification, shown in Fig. 4, the cover H
is then closed over the lid (bottom) of the box, by which the corner-folds h¹ are
formed and are laid over the lid-folds D, whereby the triple corner-folds h² are
formed by the projecting edge of the cover, so that the corners a, which may
possibly not have been perfectly tight, are now closed absolutely airtight.
As explained and shown by the drawings the construction of the above described
boxes is one and the same, the difference consists solely in the more or less
simplified execution respectively in producing an absolutely airtight fastening.
The chief aim is to supply the existing demand for a box uncommonly cheap,
easily manufactured and folded up, as well as easily unfolded and closed and
fastened airtight, which object is attained by the invention hereinbefore described.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, what I claim is:
1. A box composed of card, pasteboard or the like substantially of the form as
shown in Fig. 1, with or without the stiffening piece J or end auxiliary pieces H,
having the opposite pointed ends b, the folded corners D and the sides A. arranged,
substantially as described and shown.
2. In combination with the box covered in claim 1, a stiffening piece J arranged
under the top A. and forming in combination therewith pockets or slits into which
the ends b may be inserted forming a tighter closure, substantially as described.

page_text: 3. In combination with the box covered in claim 1, the auxiliary ends H
arranged as described for strengthening the corners double and three fold in the
manner, substantially as described.
Dated this 17th day of November 1890.
