An Improvement in Stoppers for Bottles.
We, JAMES CHARLES CUSHION, of 96 Gibbon Road, Nunhead in the County of
Surrey, Commercial Traveller, and GEORGE FREDERICK WILLIAM POWELL of No. 42
Ivydale Road, Nunhead in the County of Surrey, Gentleman, do hereby declare the
nature of this invention to be as follows:-
Our invention relates to the stoppering of bottles in such a manner that the washer
of caoutchouc or other packing material used for rendering the stoppering tight is
removed out of contact with the contents of the bottle. For this purpose, we make
the mouth of the bottle with an internal screw thread and we make a stopper of glass
or ceramic material with an external screw thread so that it can screw into the bottle
mouth, the stopper having also a projecting lip or flange which presses on a ring of
packing material placed in a circular groove formed in the top edge of the bottle
mouth. Or, when it is desired to remove the packing still farther from the contents
of the bottle, we form on the exterior of the bottle neck a projecting flange at some
distance below the top; on this flange we place the ring of packing material and then
the stopper, which is made with a downwardly projecting lip external to the bottle
mouth, being screwed in, its lip presses on the packing and renders the closure
tight.

An Improvement in Stoppers for Bottles.
We, JAMES CHARLES CUSHION of 96 Gibbon Road, Nunhead, in the County of
Surrey Commercial Traveller, and GEORGE FREDERICK WILLIAM POWELL of No. 42
Ivydale Road, Nunhead in the County of Surrey, Gentleman, 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 :-
Our invention relates to the stoppering of bottles in such a manner that the washer
of caoutchouc or other packing material used for rendering the stoppering tight is
removed out of contact with the contents of the bottle. For this purpose we make
the bottle mouth and stopper as shewn in vertical section by the accompanying
drawing. A is the upper part of the bottle neck which is made with an internal screw-
thread and an external projecting flange B some distance below the top. C is the
stopper made with an externally threaded plug D to screw into the bottle mouth and
with a downwardly projecting lip E.
On the flange B we place a ring F of caoutchouc or other suitable packing
material, and on screwing the stopper into the bottle mouth the lip E pressing on the
ring F renders the closure of the bottle tight, the packing material F being in such a
position that it is removed from direct contact with the liquor contained in the bottle.
The lip E is preferably sloped as shewn so as to prevent the washer F from being
squeezed outwards.
Having now particularly described and ascertained the nature of our invention
and in what manner the same is to be performed we declare that what we claim is :-
Closing a bottle by screwing into the bottle mouth a stopper having an externa!
downwardly projecting lip which presses on a ring of packing material interposed
between this lip and a projecting flange formed on the bottle neck, substantially as
and for the purpose herein set forth.
