I, WILLIAM LLOYD WISE, of 46, Lincoln's Inn Fields, in the County of London,
Consulting Engineer and Chartered Patent Agent, do hereby declare the nature of
this invention to be as follows:-
This invention relates to a device for jointing the corners of boxes and like
bodies of pasteboard or other flexible material, which offer the following combined
advantages over those hitherto known and in use:-
No metal binders, clamps, adhesive matter, or other separate fastening means are
required;
The corners of boxes can be closed sufficiently tight to contain powdery, sandy,
or like material;
The parts to be secured together are united so as to withstand both pressure and
tension;
The device can be used for boxes or their covers having height that render
hitherto known devices useless.
In using the device for jointing the corners of an ordinary square pasteboard
box, each side of the box is provided as usual at one end or at both ends
with a flap, which is preferably in the form or approximately in the form of a
triangle having its apex at the bottom of the box and its base at the outer and upper
edge of the side of the box. At the part corresponding to the outer end of this
base, the flap is so cut that it here forms a hook-like or tooth-like projection which
may extend downwards toward the bottom of the box. Corresponding to the dis-
tance of this projection from the corner to be closed, a cut is made in the outer
portion of the side of the box which, with the side having the flap, is formed one
corner of the box, the cut in side preferably extending from the outer and upper
edge towards the bottom of the box. If the two sides (the one with the projection
and the other with the cut) are bent up to form the corner, the projection of the
one can be hooked into the cut of the other, whereby the two sides can be firmly
united, closed, or jointed. By repeating this at all four corners a solid box having
the advantages above stated can be constructed.
The pasteboard, cut into proper shape for forming a box and provided with pro-
jections and cuts as above explained, may be sent out from the factory flat and be
subsequently bent and united as described, with ease and rapidity, when and where
the box is required.
It is preferred to give to the cut in the side of the box a slanting position so that
it shall start from the outer and upper edge of the side and proceed a short distance
downwards and at the same time towards the adjacent end of the side in which it
is made: if the hook or tooth-like projection is inserted into such a slanting cut,

withstand pressure exerted against the outside and inside of the side in a sufficient
manner.
By virtue of the flexibility of the material from which such boxes or hollow
bodies are made, the tooth or hooklike projection may be inserted down to the
bottom of the cut, and as the depth of the cut corresponds to the length of the
tooth, there will remain no aperture slit or opening in the cut for allowing powdery
or sandy material, with which the box is to be filled, to escape. By the insertion
of the projection into the cut, also, the flap is drawn round the formed corner so
as to close the corner tightly.
From what has been said, it will be readily seen that the device can be employed
for closing the corners of boxes and the like of very small height, because the sides
of the boxes, even if of very limited height, will allow one to be provided with a
hook or tooth like projection on the flap and an adjacent one to be provided with
a cut as described.

I, WILLIAM LLOYD WISE, of 46, Lincoln's Inn Fields, in the County of London,
Consulting Engineer and Chartered Patent Agent, 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 a device for jointing the corners of boxes and like
bodies of pasteboard or other flexible material, which offers the following combined
advantages.
No metal binders, clamps, adhesive matter, or other separate fastening means are
required;
The corners of boxes can be closed sufficiently tightly to contain powdery, sandy,
or like material;
The parts to be secured together are united so as to withstand both pressure and
tension;
The device can be used for boxes or their covers having height so small as to
render other devices unsuitable.
In using the device for jointing the corners of an ordinary square pasteboard
box, two parallel sides of the box are provided as usual at one end or at both ends
with a flap, which is preferably in the form or approximately in the form of a
triangle having its apex at the bottom and its base at the outer and upper
edge of the side of the box. At the part corresponding to the outer end of this
base, the flap is so cut that it here forms a hook-like or tooth-like projection which
muy extend downwards toward the bottom of the box. Corresponding to the dis-
tance of this projection from the corner to be closed, a cut is made in the outer
portion of the side of the box which, with the side having the flap, is to form one
corner of the box, the cut in the side preferably extending from the outer and upper

page_text: edge towards the bottom of the box. If the two sides (the one with the projection
and the other with the cut) are bent up to form the corner, the projection of the
one can be hooked into the cut of the other, whereby the two sides can be firmly
united, closed, or jointed. By repeating this at all four corners a solid box having
the advantages above stated can be constructed.
The pasteboard, cut into proper shape for forming a box and provided with pro-
jections and cuts as above explained, may be sent out from the factory flat and be
subsequently bent and united as described, with ease and rapidity, when and where
the box is required.
It is preferred to give to the cut in the side of the box a slanting direction so that
it shall start from the outer and upper edge of the side and proceed a short distance
downwards and at the same time towards the adjacent end of the side in which it
is made if the hook or tooth-like projection is inserted into such a slanting cut,
the joint will not only withstand strain exerted lengthwise of the side, but will also
withstand pressure exerted against the outside and inside of the side in a sufficient
manner.
The accompanying drawings illustrate a box in accordance with this invention
by way of example, Fig. 1 shows a piece of pasteboard, cut to size, suitable for
constituting a box, by bending up of the sides à dcc. Two of these sides d d are
provided with flaps a, each Hap having at its outer end a hook or tooth h, formed by
cutting the Map into suitable shape. The other two sides c c are provided with
alauting cuts, so arranged that if one side d and another c are bent up to form
a corner, the hook or tooth may be insorted in the cut z, as indicated in dotted
Ines Fig. 2 and in plan Fig. 3. The flexibility of the material allows of a tight
insertion of the hook h into the cut z, the flap a tightly closing the corner thus
formed,
By virtue of the flexibility of the material from which such boxes or hollow
bodies are made, the tooth or hooklike projection may be inserted down to the
bottom of the cut, and as the depth of the cut corresponds to the length of the
tooth, there will remain no aperture slit or opening in the cut allowing powdery or
sandy material, with which the box is adapted to be filled, to escape. By the insertion
of the projection into the cut, also, the Hap is drawn round the formed corner so
as to close the corner tightly.
From the foregoing it will be readily seen that the device can be employed for
closing the corners of boxes and the like of very small height, because the sides
of the boxes even if of very limited height, will allow of the provision of hooks or
tooth-like projections on the flaps and adjacent sides to be provided with cuts as
described.
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
1 claim is:
-w
1. Device for jointing the corners of boxes and like bodies of pasteboard and
other flexible material, comprising at each corner a hook or tooth h on the flap a
of one side of the body and a slanting cut in the adjacent side of said body for the
said hook to be inserted therein, substantially as described.
2. The device for jointing the corners of boxes and like bodies shown in and
described with reference to the drawings.
