Improvements in Stoppering Bottles.
HENRY IVAN GOULD Gentleman 43 York Street Walworth London County of
Surrey 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
A construction upon the inside of the neck of a Bottle by which the cork is

parts which form the subject of my application being capable of reduction or
increase so as to resist any pressure brought to bear upon the cork from the Aerated
water or other liquids contained in the Bottle.

page_text: Upon the upper part of the neck of the Bottle I have two or more Flanges or
projections which slant from left to right or the reverse at an angle of about
45 degrees this angle is however varied according to the pressure the fluid exercises
upon the cork.
This
These projections or flanges are "run off to nothing" at either end and have
the upper part rounded or tapered off towards the edge, which also is round-so
presenting no sharp surface to the cork when it is driven into the Bottle.
most important feature prevents the possibility of cork dust getting into the fluid
when being bottled or when the cork is withdrawn-The flange also merely dents
the cork and is thus withdrawn uninjured and fit for further use.
The underneath side of these flanges are perfectly flat and cut upwards or undercut
as it is called-giving a tighter grip upon the cork and allowing for defect in the
manufacture.
Below these Flanges I have another projecting ring making the complete circuit
of the Bottle-which is also rounded upon the top and perfectly square underneath.
The edge also being chamfered. This ring I have added as additional security for
use in Bottles where extra pressure is produced by the fluid contained therein―The
flanges in this case being continued to, and terminating at, this ring.
By the peculiar construction of these Flanges I claim that the cork can be easily
driven past them but cannot possibly be withdrawn without being slightly twisted.
This also is a feature the cork requiring to be only turned one halfway round to effect
its complete withdrawal. The flanges also by their ends being "run off to nothing
present no obstacle either in driving the cork into the Bottle or withdrawing it.
"
The width and depth and length of these Flanges are also determined by the
pressure they are required to resist i.e. The stronger the pressure the deeper and
thicker must these flanges be so making a deeper dent in the cork and consequently
holding it more firmly in its place.
For Bottled Beers &c. and fluids containing small quantities of gas. These Flanges

wire and string &c. Also by the peculiar shape or formation of the flanges and ring
which I claim as entirely novel-the corks can be used several times.
3. Finally the Bottle supplies a general want corked mineral waters &c. being
almost universally preferred and called for in preference to Bottles containing India
