Improvements in Collapsible Card-board or like Boxes.
I, GEORGE ROWLAND TAYLOR, of 1, Cawdor Road, Fallowfield, Manchester,
Gentleman, do hereby declare the nature of my said invention to be as follows:-
My invention relates to collapsible card-board or like boxes and has for its
object to produce from a single sheet of card board or other like material a box
in which tapes, cords or other devices for securing the sides when made up are
entirely dispensed with, and the rigidity of the box structure is ensured by the
manipulation only of the box material.
In accordance with my invention I form the blank of the box with scorings or
creases which produce the usual bottom, side and end parts, a flap or leaf at
the top horizontal edge of each end part, and a flap or leaf at the vertical edges of
each side part, such flaps to the said side part being formed by a slit or cut in
the box material at right or other angles to the score or crease made to form such
flap.
In each of the flaps of each side part I form an opening or gap of, by preference
approximately oval or D formation and diagonally disposed to the edges of said
flap, and into such openings, after being folded over the end flaps, curved or
tongue-like extremities on each end flap are caused to enter and engage, and thereby
lock the said sides and ends in a perfectly rigid manner.
The said vertically disposed flaps may be in the end parts and the horizontally
disposed flaps on the side parts. The lid may be constructed in one or other of the
same ways.
The said locking may also be effected on the exterior of the box, but I prefer it
to be upon the interior.
Improvements in Collapsible Card-board or like Boxes.
I, GEORGE ROWLAND TAYLOR, of 1, Cawdor Road, Fallowfield, Manchester,
Gentleman, 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:-
My invention relates to collapsible card-board or like boxes and has for its object

page_text: to produce from a single sheet of card-board or other like material a box in which
tapes, cords or other devices for securing the sides when made up are entirely
dispensed with, and the rigidity of the box structure is ensured by the manipula-
tion only of the box material.
In accordance with my invention I form the blank of the box with scorings or
creases which produce the usual bottom, side and end parts, a flap or leaf at the
top horizontal edge of each end part, and a flap or leaf at the vertical edges of
each side part, such flaps to the said side parts being formed by a slit or cut in
the box material at right or other angles to the score or crease made to form such
flap.
In each of the flaps of each side part I form an opening or gap (by preference)
approximately oval or D formation and diagonally disposed to the edges of said
flap, and into such opening in each flap after being folded over the end flaps,
curved or tongue-like extremities on each end flap are caused to enter and engage
and thereby lock the said sides and ends in a perfectly rigid manner.
The said vertically disposed flaps may be on the end parts and the horizontally
disposed flaps on the side parts. The lid may be constructed in one or other of
the same ways.
The said locking may also be effected on the exterior of the box, but I prefer it
to be upon the interior.
To permit of my invention being clearly understood and carried into practical
effect I have hereunto annexed a sheet of drawings, and will now proceed to
describe the same with the aid of the various figures and letters of reference
marked thereon:-
Fig. 1 represents a perspective view of a box constructed in accordance with
my invention and illustrating more particularly the manner in which the box
blank is formed and manipulated to produce the box, or the manner in which the
completed box is made ready for collapse.
Fig. 2 represents a similar view of the box as made up and ready for use with its
ends and sides rigidly erect.
Figs. 3 and 4 represent similar views to Figs. 1 and 2 of a modified construction,
for effecting a slight saving in material.
Figs. 5, 6 and 7 illustrate an important feature of my invention to a larger
scale.
Referring to Figs. 1 and 2. (A) is the floor of the box, (B) the sides, and (C) the
ends, all formed out of a single sheet of cardboard or box material and produced by
the usual scoring or bending.
In lieu, however, of the corner pieces (D) of the box blank being entirely cut
away, or only a small portion left for joining the ends and sides, I retain such
corner pieces as illustrated, but attached only to the sides (B).
In each of such corner pieces I form a gap or opening (E) (see Fig. 5)
approximating in shape to the letter D or a flat-sided oval and arranged at an
angle to the edges of the corner piece as illustrated.
The size of the box blank is also such as to leave at the top edge of each end (C)
an extension (F), which by scoring or bending forms a hinged flap adapted to fold
inwards on to the inner face of the end (C).
The ends of such flap are of the form shewn and each embodies a rounded
corner, tongue or shoulder (G).
The manipulation of the parts for erecting the box is as follows:-Starting
with the box collapsed, i.e., with the sides (B), and corner picces (D) folded out-
wards in the flat, or folded inwards over the floor of the box, and the ends (C)
and flaps (F) likewise folded inwards, or outwards in the flat,-in which position
they cause the box to occupy a minimum of room,-the two sides (B) are first
brought to the vertical, with the corner pieces (D) also vertical and at right angles
to the sides as shewn at the lower part of Fig. 1. One of the sides (B) is then
brought to the vertical and over both of the end pieces (D) the flap (F) is turned
down into the interior of the box until it lies flat against the end pieces.

page_text: Each end of the flap (F) at that moment lies immediately over and overlaps the
gap (E) in the corner piece (1) to an extent represented approximately by the
dotted lines in Fig. 6.
It only then remains for the overlapping portion of each flap end viz. the
shoulders or corners (G) to be sprung or guided into the gaps to effect the locking
of the end (C) in a rigid vertical attitude relatively to the floor (A).
The same description of manipulation applies to the erection and locking
of the parts belonging to the other end of the box and the appearance of the
completely erected box which is exceedingly rigid is clearly shewn in Fig. 2.
The form of the gap (E) is important. Å slit would not answer, as the corner (G)
would have to be introduced into it at a very sharp angle and therefore break the
cardboard, whereas the wide opening allows of the insertion of the flap by a very
slight bending of the flap and when such flap is inserted allows it to lie in an
almost flat condition, the degree of bending being divided between the material
of the end pieces and that of the flap as shewn by sectional plan in Fig. 7.
By such form of opening both ends of the flap can if desired be simultaneously
secured and thus effect a saving of time in erecting the box. The shape of
each corner (G) is, by preference such as, in conjunction with the shape of the
gap (,) to present a complete oval, but I may make the shoulder in any other
form suitable for entering the gap, and in such connection it may be made more
in the form of a tongue.
To save material I may use small locking flaps (*), sewn or pasted on to the
box, as shewn in Figs. 3 and 4.
In lieu of being on the ends (C) the flaps may be on the sides (B), and the end
pieces (D) may be attached to the ends (C), likewise the flaps (F) may be adapted
to fold outwards and effect the locking upon the outside of the box, but to ensure
against accidental collapse they are preferably adapted to fold inwards, and to lot
the contents of the box help in keeping the box rigid.
The lid may be made in the same manner with the folding and locking, by
preference, effected upon the sides whilst the folding and locking of the box is upon
the ends, or rice-versa.
For deep boxes the corner pieces may be merely at the top part only, sufficient
for the flap to engage with, or they may extend the full depth.
Although preferring the gap to be arranged as shewn they may be in the end
or sides and the flaps being on the corner pieces, and I may vary their proportions
and dispositions to suit requirements.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is
1. A cardboard or like box with folding ends and sides, corner pieces attached
to two opposite sides (or ends), an opening or gap such as (E) in each corner-
piece, and flaps attached to two opposite ends (or sides) and adapted to enter the
said gaps, substantially as and for the purposes herein set forth and illustrated on
the accompanying drawings.
2: In collapsible cardboard or like boxes, locking the sides and ends by
gaps or openings of the kind described, and folding flaps, substantially as set
forth.
