(57) 5n7 The two parts which make up the packaging box are produced by die-cutting from
a single sheet of cardboard, are joined together in order to form a single-piece box
and are optionally divided by cut lines and weakened lines (16, 17, 18, 19). The top
part (B) of the box has longitudinal slots (21, 22, 23, 24) cut into the corners of
its bottom part (A), these slots suitably reducing the width of that portion of the
side walls in which they are made. When it is to be used, the box is opened out, its
side walls are positioned so as to form a rectangle, and the bottom flaps are closed,
after which means act along the said cut and weakened lines in order to separate the
two parts of the box from each other and to ensure that the size of the transverse
section at the bottom of what is to be the top part (B), with the said slots cut into
the corners, is reduced so that it can be inserted telescopically into the bottom
part (A) of the said box. The box is thus ready to receive the product, and from this
point on it can be used in the same way as a conventional packaging box.
