Improvements in the folding of boxes, cases, and like articles.

Extract from Specification.-In constructing a collapsible
box or like article according to my invention two sides of the
same, the bottom and the top (or lid) are creased, scored, or
hinged in such a manner so as to be capable, when the box
is built up or completed, of being folded so as to lay in a
perfectly flat position. The other two or remaining sides
are in a perfectly plain condition. The two creased, scored,
or hinged sides are cut of a length a little larger than the
plain sides for the purpose of allowing flaps or flanges to be
made, which are at the corners thereof cut so as to form
slots and lugs or projections for the purposes of interlocking
the sides together, as will be fully explained, and also for the
purpose of providing flanges for the fastening-together of
the four sides. The lugs or projections are strengthened
by means of a piece of thin sheet metal having spikes or
legs on the inside surface for attachment to the before-men-
tioned lugs.
