I GEORGE AMBROSE WILKINS of 11 Fenchurch Avenue in the City of London,
Manufacturer, do hereby declare the nature of this invention to be as follows:-
My invention relates to an improvement in paper bottles the object being to provide
a paper botttle, having a perfect and unbroken interior coating of pitch.
Heretofore it has been impracticable to form bottles having a lining of pitch
because of the formation of apertures or bubbles, the existence of which has rendered
them unfit for holding liquids; this controlling objection is entirely overcome by my
invention.
It is well known that paper is of a very sensitive nature and contains when in its
normal state, a considerable percentage of moisture absorbed from the atmosphere.
This atmospheric moisture I have found to be the source of difficulty.
In carrying out my invention I select a good quality of paper and waterproof it,
rendering it of such a nature that during the subsequent stages of the manufacture of
the vessel the paper will not absorb any moisture. Or, I take a good quality of
paper which has already been waterproofed. Having selected a sheet of suitable
size, it is formed into a cylinder of the desired diameter and length. The head
and end constructed with relation to the diameter of the cylinder, are next introduced
and secured in place. There is thus formed a vessel or receptacle, which requires only
to be provided with the lining of pitch to be in a substantially completed condition.
The lining of pitch is formed by heating the pitch and introducing it into the vessel in
any convenient manner. If the waterproofed paper is used, as above-described, the
coating will be found to be entirely free from all bubbles or apertures, thus ensuring
the proper retention of the fluid.
In forming and coating the bottle, I recommend the employment of the machines
for which I have this day made application for letters patent designated to accomplish
especially the introduction of the heats and application of the pitch, which I regard as
the most difficult and important steps in the manufacture.

of Middlesex, Manufacturer 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 an improvement in paper bottles, the object being to provide
a paper bottle, having a perfect and unbroken interior coating of pitch.
Heretofore it has been impracticable to form bottles having a lining of pitch
because of the formation of apertures or bubbles, the existence of which has rendered

It is well known that paper is of a very sensitive nature, and contains, when in its
normal state, a considerable percentage of moisture absorbed from the atmosphere.
This atmospheric moisture I have found to be the source of difficulty. In carrying
out my invention I select a good quality of paper and waterproof it, rendering it of
such nature that during the subsequent stages of the manufacture of the vessel the
paper will not absorb any moisture. Or I take a good quality of paper which has
already been waterproofed. Having selected a sheet of suitable size, it is formed into
a cylinder of the desired diameter and length. The head and end constructed with

There is thus formed a vessel or receptacle, which requires only to be provided with

found to be entirely free from all bubbles or apertures thus ensuring the proper
retention of the fluid.
In forming and coating the bottle, I recommend the employment of the machines
for which I made application for letters patent, on the 12th of April 1887
designated to accomplish especially the introduction of the heats and application
of the pitch, which I regard as the most difficult and important steps in the
manufacture.
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 :-
A bottle constructed of paper, and lined with pitch, the paper previous to the
application of the lining being waterproofed.
