IMPROVEMENTS IN PAPER BOXES
Year: 1885

page_text: I ALFRED JULIUS BOULT of 323 High Holborn in the county of Middlesex,
Engineer do hereby declare the nature of this invention for IMPROVEMENTS
IN PAPER BOXES (a communication from Frank Peart Birley of Toronto in the
dominion of Canada, Manufacturer) 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 an improvement in the manufacture of paper boxes
such as are made and folded from a single sheet cut to the proper shape and
designed for the putting up of various articles of manufacture; and the object of
the present invention is to so cut and fold the paper blank used in forming the box
that the least possible waste of material shall be caused and that the ends shall be
so folded independent of each other that substantially the same form of blank may
be used either for a single or a double ended box; and it consists in the method of
cutting and folding the blank substantially as shown in the accompanying drawing
and hereinafter more particularly explained.
Figure 1 represents a plan of the blank as it will be formed when designed for
a single end box.
Figure 2 is a similar view of the blank when made for a double ended box.
Figure 3 is a perspective view showing the blank folded to form the box but
without being glued together or the end flaps turned in.
Figure 4 is a perspective view showing the inside portion of the end turned in,
one of the side flaps folded and turned under, its fellow flap standing before folding
and the outside or locking piece of the bottom likewise standing.
Figure 5 is a similar perspective view but showing the flaps folded and bent
down.
In Figures 1 and 2 the solid lines indicate where the paper or other material is
cut while the dotted lines indicate the lines on which the parts are folded or bent.
In Figures 1 and 2 A forms one side of the box; B its adjoining side; C the side
of the box opposite to A; and D the side of the box opposite to B; while the
flap E is designed to fit below and be pasted to the outer edge of the side A. Of

page_text: course the same effect will be produced by placing the flap E on the outer edge of
the side A so that it would be pasted or gummed to the side D. The part
marked F forms the inside portion of the bottom and the parts G and H form the
side flaps which are folded diagonally and then folded down upon the inside
portion F of the bottom. The outside portion portion I is then folded down and
the flap J bent and slipped under the flaps G and H which form a complete lock
and secures the bottom together and as any inside pressure on the portion F merely
tends to grip the flap J more securely between it and the flaps G and H the
pressure from the goods ensures a solid bottom.
It will be noticed on reference to the drawing that the only difference between
the blanks forming a single ended or double ended box is that the parts
marked G F H I and J are duplicated for a double ended box.
Although the flap E is necessary in order to make a complete and really
serviceable box, the advantages of this improved form of bottom would be secured
even though the said flap E was dispensed with. The claim is therefore not to be
confined to the use of the said flap and it will further be seen that although it will
be preferable (being easier) to fold the flaps G and H diagonally they would
perform their principal function were the piece of each which is folded undercut
entirely away and the bottom might also be made without even folding the
flaps GJ.
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 correspondent I declare that what I claim is
1. As an article of manufacture the herein described box consisting of the
sides A B C and D with the flaps F G H and I and flap J cut and folded
substantially as described.
2. As an article of manufacture the berein described box consisting of the
sides A B C and D and flap E with the parts F G H and I and flap J cut and
folded substantially as described.
Dated this 30th day of June 1885.
