Complete Specification Left, 8th June, 1896-Accepted, 11th July, 1896
PROVISIONAL SPECIFICATION.
Improvement connected with Stoppering or Closing the Tops of
Bottles and the like.
I, EDWARD PINK, of 1 Southwark Park Road, London, S.E. Manufacturer, do
hereby declare the nature of this invention to be as follows:-
This invention refers to a simple or simplified arrangement for securing a
stopper to the top of a bottle or jar by atmospheric pressure. The stopper is
preferred to be a metallic disc with a flange or rim turned at right angles, and with
the edge turned out and partly round within which latter part is held an india
rubber washer to bear upon the top of the mouth of bottle or jar. In applying this
stopper, the bottle or jar is first filled, the stopper put on and held in its place by
any suitable spring clip and the bottle or jar, subjected to heat to produce a slight
vacuum, this causes the atmospheric pressure to act upon outside of stopper and
press it down upon the top of neck of bottle, thereby securely holding it in position,
then the spring clip is removed. The right angle rim of the stopper is made to
fit the inside of the neck of the bottle to assist in securing the stopper against
tangential movement.

COMPLETE SPECIFICATION.
Improvement connected with Stoppering or Closing the Tops of
Bottles and the like.
I, EDWARD PINK of 1 Southwark Park Road, London, S.E. 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 :-
This invention refers to an improved arrangement of stopper for securing the
same to the top of a bottle or jar by atmospheric pressure.
To enable the invention to be properly understood I will proceed to describe the
same with aid of the accompanying drawings, in which:
Fig. 1, is a partial sectional elevation of a bottle fitted with a stopper according
to this invention.
Fig. 2, top plan of same.
Fig. 3, a partial sectional elevation shewing a slightly different shape for the
stopper.
A, illustrates the body of bottle or jar, A', the top of neck, B, an india rubber or
other suitable washer: C, the stopper. The latter is preferred to be made of
metal and of a suitable size to enter the mouth of bottle. The stopper is formed
with a turned over portion C', to enable it to hold and bear upon the india rubber
washer B. In applying this stopper to a bottle or jar it is fitted on as shewn
at Fig. 1, after the bottle or jar has been filled, the stopper is then held in place by
317

page_text: spring clip or other suitable means such as by weight resting on it, and the bottle
or jar subjected to suitable means to produce a slight vacuum in same, such
as heating the bottle or jar, this causes the atmospheric pressure to act upon outside
of stopper and press it down upon top of neck A¹, of bottle thereby by aid of the
washer B, securing the stopper in position and hermetically sealing the contents of
bottle. After the stopper has been secured as stated the clip or other means
-employed to hold stopper while the vacuum is being created, is removed.
Fig. 3, illustrates a similar arrangement with a flat washer B, the turned over
part C', being made to correspond.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, I declare that I am
aware that stoppers have been proposed to be secured by atmospheric pressure,
I therefore do not broadly claim the same, but what I claim as my invention is:
A stopper for bottles or jars and the like to be secured by atmospheric pressure
-constructed and arranged as herein before described and illustrated by the
-accompanying drawings.
