Improvements in the Manufacture of Boxes made of Cardboard,
Strawboard, and Analogous Materials.
We, ARTHUR WILLIAM STEVENSON and ALBERT HUGH STEVENSON, both of the Firm
of Hugh Stevenson and Sons, of Bridge Street, Ardwick, Manchester, in the County of
Lancaster, Paper Box Manufacturers, 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 :-
Our invention relates to improvements in the manufacture of straight sided boxes
made of cardboard and analogous materials such as strawboard, and wood pulp boards
of all kinds, which materials for convenience of description are hereinafter referred to
as cardboard.
Prior to our invention it has been customary to make a certain class of straight
sided cardboard boxes with a shoulder projecting above the top of the sides of the
box which sides form a ledge upon which the lid when closed rests in the same
vertical plane as the outside of the box thus forming what is known in the trade as a
"flush lid" box.
Our present improvements consist principally in dispensing with the separate
lining or strip hitherto employed in the manufacture of this class of box and forming
the top rim or shoulder over which the lid fits, the ledge upon which the lid rests,
and the sides of the box, all out of one piece of cardboard, and in such a manner that
when the lid is closed its sides will be in the same vertical planes as the corresponding
sides of the box.
In the accompanying sheet of drawings-
Figure 1 is an outside elevation of a straight sided cardboard box made according
to our improvements, the lid being indicated by dotted double lines. Figure 2 is a
sectional elevation on a larger scale of part of the box. Fig. 3 is a plan, Fig. 4 a
longitudinal section, and Fig. 5 a transverse section of the bottom and sides of the
box before the latter are turned up and fastened at the corners.
In these views 1 denotes a sheet of cardboard which is scored or grooved along the
lines 2 to facilitate the bending up of the flaps 3, and end pieces 4 to form the sides
of the box, the flaps 3 and end pieces 4 being cut out by the usual or any suitable
known means.
According to our improvements we prefer to employ heat or moisture and pressure
applied by stamping dies or embossing rollers in order to leave in a different plane a
raised longitudinal strip 5 along the outer side of each side flap 3 and end piece 4.
When the sides are turned or bent up the corners are made up with paper, cloth or
like material pasted or otherwise caused to adhere thereto or by wire stitches or any
The
of the other known modes of making up the corners of cardboard boxes.
longitudinal strips 5 come together and form the top rim of the box over which the
lid 6 fits snugly, see Fig. 1, and rests upon the ledge 7 with each of its sides in
the same vertical plane as the corresponding side of the body of the box.
In order to insure close fitting of the ends of the longitudinal strips 5 which form
the top rim we cut away the cardboard to the required depth at each corner as
clearly shown in the plan view, Fig. 3.

page_text: After the corners have been made up the box is ready for use or the sides may
be covered with a bauding strip or two or more separate banding strips applied in
one machine and at one operation in the ordinary way well known by makers of
cardboard boxes.
Instead of scoring or grooving the cardboard the sides may be bent up in a
suitable bending machine.
We prefer to employ pressure, applied by stamping dies or embossing rollers
but we might form the top rim by double scoring or grooving the side flaps 3
and end pieces 4 and then bending the longitudinal strips 5 into the form shown
before making up the corners.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed we declare that what
we claim is :-
1. Forming the top rim over which the lid fits, the ledge upon which the lid rests
and the sides of a straight sided box out of a single sheet of cardboard in such a
manner that when the lid is closed each of its sides will be in the same vertical
plane as the corresponding side of the box substantially as herein set forth.
2. The improved straight sided cardboard box formed substantially in the manner
herein described and as illustrated by the accompanying drawings.
