Improvements in and relating to the Manufacture of Paper Bottles
and Boxes.
I GEORGE AMBROSE WILKINS, of Billiter Buildings, Billiter Square, in the City of
London, Mechanical Engineer, 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 the manufacture of bottles and boxes of paper, and to the
coating or other treatment thereof with inodorous substances to render them
impervious to oils or other liquids or substances for which they may be required.
The main object of my present invention is the manufacture of corrugated. paper
bottles or boxes coated or otherwise treated with inodorous substances.
These bottles and boxes are made by forming a hollow or tubular body from a
sheet of paper by rolling (the number of convolutions being varied according to the
desired strength and thickness of the bottle or box), and then fixing an end-piece or
end-pieces in the said hollow or tubular body. In making bottles, one of these end-
pieces is formed with a suitable opening for the introduction into the bottle of the
liquid or other substance which it is to contain. In making the paper boxes, a
bottom is fixed in the hollow or tubular body and a lid or cover is made for the top
thereof.
I sometimes form a screw-thread in or upon one end of the said tubular body and
provide a screw-cap or screw-stopper which fits into or upon the screw-threaded end
thereof.
I make the said bottles or boxes with corrugations extending either longitudinally,
circumferentially or spirally, and the bottle or box may be corrugated from end to
end, or only partially throughout the length of the same, leaving the ends smooth or
uncorrugated.
Bottles or boxes having longitudinal corrugations extending from end to end
thereof can be made by means of a machine provided with a corrugated mandrel upon
which the paper is rolled and a corresponding corrugated roller between which and
the mandrel the paper is passed.
These bottles and boxes can, moreover, be made in series, that is to say, a long
corrugated hollow cylinder or tube may be made and cut into lengths or pieces to form

page_text: several bodies of bottles or boxes. The ends of the bottles or boxes are made by
means of cutting dies of such form that they will impart the requisite shape or
configuration to the said ends, so that the latter will fit the corrugated bodies.
In making bottles or boxes with corrugations extending circumferentially or spirally
around the same, or extending longitudinally only partially throughout the length of
the bottle or box, I use an expansible mandrel of the required shape in combination
with a roll of corresponding shape. The said mandrel may be constructed in any
convenient manner, so that it can be expanded to permit the paper to be rolled or
wound thereon and can then be contracted to permit its withdrawal from the corrugated
hollow cylinder or tube.
I
can,
however, manufacture my improved bottles or boxes by first corrugating a
sheet of paper and then forming the same into a tube by rolling it and applying
adhesive material thereto by hand.
When the bottle or box is completed, I coat or otherwise treat the same on the
inner or outer surfaces or both, with pitch, paraffin, or other suitable material which
is capable of rendering the bottle or box impervious to water, oil or other liquids or
substances, and which if not inodorous should, when the bottle or box is to be used
for containing food, be deodorized in any well known or suitable manner.
I thus produce a cheap and light vessel for containing liquids and other substances
and one which is not liable to breakage and which will not affect or be affected by
the contents thereof.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I wish it under-
stood that I claim ;-
First. The manufacture of a corrugated paper bottle or box substantially as
hereinbefore described.
Second. A paper bottle or box provided with a screw-cap or screw-stopper, sub-
stantially as set forth.
