PROVISIONAL SPECIFICATION.
An Improved Method of Stoppering Bottles, Jars, and the like.
1, JOHN DOCKETT, of High Street, Exmouth, in the County of Devon, Wine and
Spirit Merchant, do hereby declare the nature of this invention to be as follows:-
This invention consists in an improved method of stoppering bottles, jars and the
like.
The stopper is in the forin of a cover having internal screw threads. It is screwed
down on the bottle neck which is provided externally with screw threads corresponding
with the internal threads of the stopper.
In the mouth of the bottle is a ring of cork which extends downwards from the top
of the neck to a suitable distance and constitutes a cylindrical lining to the neck
against the interior of which it bears.
Projecting centrally downwards from the inside of the top of the stopper is a plug
which decreases in diameter as it extends downwards. That is to say, the plug is
conical and has its point downwards.
When applied to a bottle, jar, or the like vessel, the stopper is screwed down and
the plug is thereby forced into the cork ring thus closing the mouth of the vessel.
The further the plug is forced down in the ring the more effectual is the closing. To
prevent the cork ring from being forced out of place down into the bottle, the neck is
contracted from the top downwards so that the ring forms a hollow truncated cone of
which the larger end is uppermost.
COMPLETE SPECIFICATION.
An Improved Method of Stoppering Bottles, Jars, and the like.
I, JOHN DOCKETT, of High Street, Exmouth, in the County of Devon, Wine and
Spirit Merchant, 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 :-
This invention consists in an improved method of stoppering hottles, jars and the
liko.
The stopper is in the form of a cover having internal screw threads. It is screwed
down on the bottle neck which is provided externally with screw threads corresponding
with the internal threads of the stopper.
In the mouth of the bottle is a ring of cork which extends downwards from the top
of the neck to a suitable distance and constitutes a conical lining to the neck against
the interior of which it bears.
Projecting centrally downwards from the inside of the top of the stopper is a plug
which decreases in diameter as it extends downwards. That is to say, the plug is
conical and has its point downwards.
When applied to a bottle, jar, or the like vessel, the stopper is screwed down and
the plug is thereby forced into the cork ring thus closing the mouth of the
vessel.
The further the plug is forced down in the ring the more effectual is the
closing.
To prevent the cork ring from being forced out of place down into the bottle, the
neck is contracted from the top downwards so that the ring forms a hollow truncated
cone of which the larger end is uppermost.

page_text: The accompanying drawing represents a vertical section of the top of a bottle living
my improved means for stoppering applied thereto. The stopper a which is in the
form of a cover is provided with screw threads which work over corresponding threads
formed on the neck of the bottle.
In the mouth of the bottle is a ring or thimble e of cork, approximately conical and
curved to fit in the neck which is correspondingly curved, as shown.
Extending downwards from the inside of the top of the cover a is a conical plug d
formed in one piece with the cover a.
Accordingly, as the latter is screwed down on the neck of the bottle the plug dis
forced into the ring and bears against it with a pressure increasing as the stopper is
screwed down.
Consequently, the further the stopper is screwed down the tighter is the closing of
the vessel. The ring or thimble e resembles in shape a truncated hollow cone and as
it has the largest end at the top it cannot be forced into the bottle or vessel by screwing
on the cover.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
Improved means for stoppering bottles, jars and the like, consisting of a screwed
stopper such as a with central plug d which, as the stopper is screwed on the hottle
neck, enters a cork ring e fitted in the neck of the vessel and pressing on the said ring
closes the vessel with increased tightness as the cover is screwed down, substantially
as hereinbefore described with reference to the accompanying drawing.
