Improved Cardboard Box and its Manufacture.
I, JOSEF TEMLER, of Warsaw in the Empire of Russia, and of 30 to 34 Taber-
nacle Street in the County of London, 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 present improvement relates to cardboard boxes of that kind in which the
bottom and sides are separately made and then united. In this box a novel means
for connecting these two parts is employed as will presently be explained and as is
illustrated in the accompanying drawings.
Fig. 1 shows such a box in section. Fig. 2 shows a plan thereof. The rim a of
the box is of suitable outline and inserted in a metal frame 6 the outer edge of
which is suitably channelled, and the rim a is forced into the frame 6 by the
bottom c of the box, and conversely the bottom cis held in place owing to the rim a
being forced against the bottom by the frame b, thus the whole is held together.
The process of making these boxes is as follows:-
As shown in Fig. 3 of the drawings the strip of cardboard a which is to form the
sides (or rim) of the box is provided with a moulding or beading a 1 at its edge.
This may be most conveniently made by taking a strip of suitable width to form
two rims and in the middle forming a groove such as shown in Fig. 4 by "stowing'
or upsetting." If then this strip is cut through in the centre of the groove it
forms two strips a with the curved beading a 1 shown in Fig. 3.

"
Fig. 5 represents in section the metal frame b serving to connect the sides and
bottom. Its outer rim has the shape of a little channel or groove. Size and shape
of the frame vary according to size and shape of the box to be produced.
The strip a shaped as shown in Fig. 3, is inserted in the frame b so that the
moulding or beading a 1 engages with the groove in the metal frame as shown in
Fig. 6, and then the ends of the strip a are united.
The bottom c, cut to suitable shape and size, is inserted into the rim a from the
side opposite to that at which the frame b is placed and in this operation advantage
is taken of the elasticity inherent in the cardboard (though it is but slight) and the
bottom is pushed down until it touches the frame b. When brought into position
the edge of the bottom piece c forces the beading on a into the channelled part of
frame and is in turn held fast by the said curved moulding.
The beading a 1 at the edge of the strip a may with the same effect be shaped
differently, for instance as shewn in Fig. 7. In this case, when the strip is inserted
in the frame, the groove produced on the strip a is so placed, that the edge of the
groove in the frame engages with the groove in the strip as shown in Fig. 8.
Cardboard boxes consisting of a rim, a bottom piece and a metal frame connecting
the former are thoroughly protected against tearing at the part most exposed
thereto. As the channelled edge of the frame slightly projects beyond the edge of
the box it gives a ready hold to the hand for opening the box, and moreover,
metal rim is ornamental.
the
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. Cardboard boxes in which the side or rim portion a and the bottom piece c
are connected by a metal frame forcing one against the other.

page_text: 2. In cardboard boxes such as indicated in Claim 1 the use of a metal frame b
with a channelled or grooved edge serving to connect the rim a with the bottom
-piece c..
3. The process of manufacturing cardboard boxes such as indicated in Claim 1,
characterised by producing a bead or moulding a 1 on the rim a, the rim being then
inserted in a metal frame channelled or grooved in sectional elevation the bottom
piece c being then pushed in from above until it is "sprung" into the beading a 1
whereby the rim a is fixed in the groove of frame 6 and the bottom piece c retained
in its place.
