Improvements in and relating to Cardboard and like Boxes
or Cases.
I, HENRY HARRIS LAKE, of the Firm of Haseltine Lake & Co., Patent
Agents, 45 Southampton Buildings, in the County of Middlesex, 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 cardboard boxes and like boxes or cases.
According to said invention such boxes or cases are manufactured, without the
aid of adhesive substances or fastening devices and without metallic corner pieces,
by cutting or stamping a flat piece of cardboard in such a manner that it forms
the bottom A and the sides B together with the connecting flap or corner piece C
of the box or case, as shown in Figure 1 wherein the sides and flap are bent into
the plane of the bottom. Along the dotted lines the cardboard is scored for
enabling the sides to be more easily bent upwards. After the sides have been thus
bent the connecting flap C, at the edges of these sides which are now vertical, is
bent on to the sides immediately adjoining, the tongues D which are separated
from the body of the connecting flap C by incisions E being passed through slits F
in the said sides, thus obtaining a box or case possessing sufficient strength for
many purposes for which it is used.
To prevent the tongues D slipping accidentally from the slits F it is sufficient
to make these tongues somewhat broader at their outer rounded ends towards the
side B on which they are provided, and to give the incisions E a curved form
to correspond therewith, as represented in Figure 1.
The cover for such a box or case may similarly be made either separate there-
from or adhering to one of its sides as represented in Figure 3, wherein A¹
designates the top of the cover and B' B' B' the sides of the cover.
The formation of the box or case together with the cover from a flat piece of
cardboard will not present any difficulty.
The arrangement of the connecting flaps C on the sides B is capable of
numerous modifications. Figure 2 shows by way of example an arrangement in
which for the connection of two adjoining sides B use is made of two connecting
flaps provided on the latter, the tongues D of these flaps being passed from the
outside and inside through the corresponding slits F in the two sides.
The chief advantage of these cardboard boxes or cases is that the pieces of
cardboard, from which they are made may be finished in the factory and may
then be sent away spread out flat. At the place where they are to be used the
boxes or cases can be very easily and rapidly made as they are required from
the pieces of cardboard, so that, as compared with ordinary boxes or cases, a
great saving of freight and of space for keeping boxes or cases is achieved.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed, as communicated to me
by my foreign correspondents I declare that what I claim is :-
1. For the manufacture of boxes or cases a flat piece of cardboard which
consists of the bottom part A and the sides B connected therewith, some or all
of these sides having on one or both of their free lateral edges connecting flaps C
which are pressed on to the upwardly bent and adjoining sides with which they

page_text: are connected by tongues D passed through the slits F in the said sides, these
tongues being rounded at their end, made somewhat broader towards the side B
on which they are arranged, and separated from the body of the flaps by curved
incisions.
Second. A cardboard box or case of the kind set forth in the first claim, in
which the cover is made in one piece with the body, the parts which are designed
for them adhering together at one edge of the cover top and one edge of the side
of the box or case.
Dated this 1st day of September 1893.
