Liquids.
I, JOHN WILKINSON of Beech Villa, Swinton in the County of York, Bottle
Manufacturer do hereby declare the nature of my invention for "AN IMPROVEMENT
IN STOPPERING. BOTTLES CONTAINING AËRATED LIQUIDS" to be as follows:-
For stoppering a bottle containing an aërated liquid a ball, which is generally of
glass or ceramic material is employed to act as a valve pressed by the internal
pressure against a ring or collar of caoutchouc or other elastic material which is
placed on a shoulder or rebate in the neck of the bottle, and is held in place by an
external ring or tubular cap fixed therein. Such external ring or cap is objected
to as being liable to corrosion and discoloration, and as moreover not ensuring that
the elastic ring shall be so tightly fitted into the bottle neck as to prevent leakage.
Now, according to my invention, I make the elastic collar with an internal ring of
yielding but comparatively inelastic material such as soft metal, and having
inserted this composite collar into the bottle neck in a position facing a circular
groove formed therein, I by means of a cone introduced into the collar expand it
so as to cause its periphery to engage tightly in the groove in which it remains,
the inelastic ring within it preventing it from contracting in diameter and thus it
cannot escape from the groove, nor allow leakage past it.

An Improvement in Stoppering Bottles Containing Aörated
Liquids.
I, JOHN WILKINSON of Beech Villa, Swinton in the County of York, Bottle
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:-
For stoppering a bottle containing an aërated liquid a ball which is generally of
glass or ceramic material is employed to act as a valve pressed by the internal
pressure against a ring or collar of caoutchouc or other elastic material which is
placed on a shoulder or rebate in the neck of the bottle, and is held in place by an
external ring or tubular cap fixed therein. Such external ring or cap is objected
to as being liable to corrosion and discoloration, and as moreover not ensuring that
the elastic ring shall be so tightly fitted into the bottle neck as to prevent leakage.
Now, according to my invention, I make the elastic collar with an internal ring of
yielding but comparatively inelastic material such as soft metal textile material or
hard caoutchouc imbedded therein and having inserted this composite collar into
the bottle neck in a position facing a circular groove formed therein, I by means
of a cone introduced into the collar expand it so as to cause its periphery to engage
tightly in the groove in which it remains, the inelastic ring within it preventing
it from contracting in diameter and thus it cannot escape from the groove, nor
allow leakage past it.
Fig. 1 of the accompanying drawing shews a plan of a ring or collar constructed
according to my above described invention, and Fig. 2 shews a section of the same,
inserted into the groove of a bottle. A is the elastic material such as caoutchouc,
in which is imbedded a ring B of soft metal or other material.
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
The use for stoppering bottles of an elastic collar having a ring of yielding but
comparatively inelastic material imbedded within it, so that when the collar is
expanded into the groove in the neck of the bottle, it will be held securely therein
by the expanded internal ring, substantially as herein described.
