page_text: I, BRUNO RÜCKERT of Leipsig in the Kingdom of Saxony and Empire, of
Germany, Inventor, 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 :-
J
The purpose of this invention is to construct a paste-board box, the closed
hollow space of which, is not formed until the box has to be used, and the reasons
which urge me to make these improvements are;
Firstly, the disproportionately great expense which the transporting. of empty
paste-board boxes occasions,
Secondly, the great amount of space they take up when, not used, and
Thirdly, the impossibility of preventing the boxes being damaged before being
taken into use.
Inventor is aware that there are already in use paste-board-boxes the hollow
space of which is done away with-for the purpose of removing the evils just
named by folding the parts together, but such constructions necessitate a dis-
advantageous deviation from the form of paste-board boxes mostly used, in which
the lid is lifted off from the top, and the corners of the sides are closed tight and
admit no dust. Another disadvantage of the paste-board boxes commonly used is
that the sides bend outwards at the upper edge and that the corners of the latter
are easily torn.
With a view to removing the drawbacks just enumerated the paste-board box
représented in Figs 1 to 5 has been invented. It can not only be easily and
cheaply transported and stored conveniently in a small space but it also proves as
firm and durable as possible when the projections a are made to the sides of the
under box and when the thread b is applied to the closing corners of the ends of
the box.
The box A and the lid B are each stamped out of a piece of suitable pasteboard,
Figs. 1 and 5, and to form the sides d e f and g corresponding grooves h are
impressed.
On the inner side of the closing-corners i so much of the material is pared or
split off that only a thin skin remains and the closing-corners i can be joined like
paper to the outside of the sides e and g. By this means neither the closing-
corners nor the corners of the sides of the box and the lid show, when the
sides d e f g are joined any material exposed to rent or destruction.

page_text: The closing-corners i are covered on the inside with an adhesive substance,
which is left to dry and is not used until the boxes are used at some later time.
With a view to prevent the perpendicular corners of the box and the lid from
being torn the upper edges of the sides and ends of the under-box A are made a
little longer and these projections a are bent inwards; this makes the sides and
ends d e and fg so stiff that they do not bend, except of course when the box is
destroyed. For the purpose of keeping the perpendicular corners on the upper-
edge of the box A from being torn down when the box happens to be overfilled,
threads b are glued on to the closing-corners i of the ends in such a way, that the
corners of the box are encircled by them and the tearing down of the corners is
thus prevented. The inserting of the threads b into the closing-corners i and the
ends eg is done in the following manner: the thread is carried by a special
instrument in which it is soaked in the adhesive substance, the closing-corner is
then pressed down so as to cause a split. in the upper edge of the ends e g; the
thread is laid into this cleft, as Figs. 1, 2, 4 and 5 show, and cut off at the edge of
the closing-corner i, and when the boxes are set-up for use it is stuck between the
closing-corners i and the ends d f of the box.
Fig. 1 shows the shape of the pasteboard box A with the stiffening edges a and
the thread b which is laid between the ends eg and closing-corners i, all being
shown as it is before the box is taken into use.
Fig. 2 is a section through the box when the latter is joined together ready for
use, and shows likewise the stiffening edges a and the thread b. Fig. 3 represents
a section through the box when set up ready for use.
In Figs. 4 and 5 a lid B is represented in the same way, the stiffening edges a
being dispensed with in this case. The improvements just mentioned: the
stiffening edges a and the inserted thread 6 are such as to allow of the boxes
being made in manufactories but they are not finished, that is to say set up or
joined, in the way described before arriving at the place where they have to be
used. The stiffening edges a and the thread b give these pasteboard boxes a far
greater amount of firmness than the pasteboard boxes commonly used and con-
sisting of underpart A and removable lid B ever had.
Having now particularly described and ascertained the nature of the said
invention, and in what manner the same is to be performed, I declare that what
I claim is ;
1.) The pared or split off closing-corners i on the inner surface of the pasteboard
parts A and B, for the purpose of obtaining closing-corners that do not rend and
are not so liable to destruction.
.
2.) The closing-corners i provided on their inner surface with a dried adhesive
substance, for the purpose of joining the sides de f g firmly together at some later
time by making the adhesive substance wet again.
3.) A folded-up, pasteboard material all parts of which are ready made for use
and can be ornamented if required, and which pasteboard material can with
assistance of the closing-corners mentioned in claims 1 and 2 be set up or joined
together into a box consisting of box A and lid B without any further trouble.
4.) A pasteboard box, with stiffening edges a that can be painted or ornainented
in any other way, and with the thread b which is laid in between the sides and
the closing-corners and encircles the corners of the box when the latter is set up or
joined together and makes it very firm and durable.
