PROVISIONAL SPECIFICATION.
Improvements in Stoppering or Closing Bottles, Jars, and similar
Vessels.
We CHARLES HERBERT COBBOLD, of Rose Hill, Dodworth, in the County of York,
Mining Engineer, and WILTON BROOKE, of Ashville, Stairfoot, Barnsley, in the
said County, Glass Works Manager, do hereby declare the nature of this invention
to be as follows:-
This invention relates to that class of Bottles or Jars which are used for
preserving milk, soups, fruit, or other articles, and has particular reference to
hermetically sealing, stoppering, or closing such Bottles or Jars in a simple, cheap,
and efficient manner.
According to our improvements we make a recess or groove or ledge horizontally
round the interior of the mouth or nozzle of the Bottle about a quarter of an inch
or other suitable distance from the top of the mouth. In this recess or groove and
on this ledge we place an elastic ring preferably of square or rectangular or flat
cross section, or the ring may be of any other suitable form adapted for making
a joint with the stopper. We then take a stopper of tin or other suitable material,
which stopper fits or loosely passes inside the Bottle mouth and rests on the elastic
ring for the purpose of making an airtight joint. The stopper is preferably made
of tin and of dish shape with an outer rim projecting on to the top of the bottle
mouth and preventing the admission of dust between the stopper and the interior
of the bottle mouth.
The sealing of the Bottle or Jar is effected in the following manner:-The
article to be preserved is placed in the Bottle or Jar either before or after the
elastic ring is placed in its position in the groove or on the ledge, and the groove
may be so formed that it will securely hold the elastic ring. After the Bottle or
Jar has received its contents the stopper is placed in position, and a clip or holder
is placed or passed over the stopper. This clip may have claws or bent ends for
engaging under a rim formed outside the Bottle mouth or neck. The Bottle with
its contents is then placed in a bath or oven or other suitable vessel or receptacle,
in order that the contents of the Bottle or Jar mav be sterilized or cooked or
heated. During this heating process the atmospheric air is forced out of the
Bottle, the clip being made of spring steel or other suitable yielding material to
allow of the escape of the air from the Bottle by the pressure of the steam
generated within the Bottle. As the Bottle and its contents are allowed to cool
the steam within the Bottle condenses and produces a vacuum and the pressure
of the atmosphere thus combines with the clip or other holder in securing the
stopper in airtight position. When the Bottle and its contents have sufficiently
cooled and the stopper has become fixed in airtight position, the clip may be
removed and the pressure of the atmosphere entirely relied upon for keeping the
stopper in airtight position until it is desired to open the Bottle and use the
contents. If thought necessary or required for the purpose of trade or advertise-
ments a metallic or paper or other capsule or label may be placed over the stopper

page_text: and Bottle mouth when the clip or holder has been removed, and this capsule or
label would serve to prevent the stopper being tampered with or the sealing
accidentally broken.
The air may also be exhausted from the Bottle by means of an air pump or in
any other suitable way. The stopper may also be made of glass, earthenware, or
other suitable material, and can be used an unlimited number of times,
as it can be removed by inserting any convenient instrument between
the lip of the Bottle and the turned over edge or rim of the stopper which
need not be destroyed or damaged in opening as is the case with many stoppers
used for vacuum Bottles. But in the case of the tin or metallic stoppers it is not
necessary to remove the stoppers in the way just mentioned, as by simply piercing
the cap the vacuum is relieved and the cap may be lifted off. The rubber ring or
other elastic ring being retained in the groove is not lost as in other vacuum
Bottles where the ring is attached to the stopper, and a continuous expense is thus
saved.

COMPLETE SPECIFICATION.
Improvements in Stoppering or Closing Bottles, Jars, and similar
Vessels.
We CHARLES HERBERT COBBOLD of Rose Hill, Dodworth, in the County of York
Mining Engineer, and WILTON BROOKE, of Ashville, Stairfoot, Barnsley, in the
said County, Glassworks Manager, 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 relates to that class of Bottles or Jars which are used for
preserving milk, soups, fruit, or other articles, and has particular reference to
hermetically sealing, stoppering or closing such Bottles or Jars in a simple, cheap,
and efficient manner.
According to our improvements we make, a recess or groove or ledge horizontally
round the interior of the mouth or nozzle of the Bottle about a quarter of an inch
or other suitable distance from the top of the mouth. In this recess or groove and
on this ledge we place an elastic ring preferably of square or rectangular or flat
cross section, or the ring may be of any other suitable form adapted for making a
joint with the stopper. We then take a stopper of tin or other suitable material,
which stopper fits or loosely passes inside, the bottle mouth and rests on the elastic
ring for the purpose of making an airtight joint. The stopper is preferably made
of tin and of dish shape with an outer rim projecting on to the top of the bottle
mouth and preventing the admission of dust between the stopper and the interior
of the bottle mouth.
The sealing of the Bottle or Jar is effected in the following manner:-The
article to be preserved is placed in the Bottle or Jar either before or after the
elastic ring is placed in its position in the groove or on the ledge, and the groove
may be so formed that it will securely hold the elastic ring. After the Bottle or
Jar has received its contents the stopper.is placed in position, and a clip or holder
is placed or passed over the stopper. This clip may have claws or bent ends for
engaging under a rim formed outside the Bottle mouth or neck. The Bottle with
its contents is then placed in a bath or oven or other suitable vessel or receptacle,

page_text: in order that the contents of the Bottle or Jar may be sterilized or cooked or heated.
During this heating process the atmospheric air is forced out of the Bottle, the
clip being made of spring steel or other suitable yielding material to allow of
the escape of the air from the Bottle by the pressure of the steam generated within the
Bottle. As the Bottle and its contents are allowed to cool the steam within the
Bottle condenses and produces a vacuum and the pressure of the atmosphere thus
combines with the clip or other holder in securing the stopper in airtight position.
When the Bottle and its contents have sufficiently cooled and the stopper has
become fixed in airtight position, the clip may be removed and the pressure of the
atmosphere entirely relied upon for keeping the stopper in airtight position until
it is desired to open the Bottle and use the contents. If thought necessary or
required for the purpose of trade or advertisements a metallic or paper or other
capsule or label may be placed over the stopper and Bottle mouth when the clip
or holder has been removed and this capsule or label would serve to prevent the
stopper being tampered with or the sealing accidentally broken.
The air may also be exhausted from the Bottle by means of an air pump or in
any other suitable way. The stopper may also be made of glass, earthenware, or
other suitable material, and can be used an unlimited number of times, as it can
be removed by inserting any convenient instrument between the lip of the Bottle
and the turned over edge or rim of the stopper which need not be destroyed or
damaged in opening as is the case with many stoppers used for vacuum Bottles.
But in the case of the tin or metallic stoppers it is not necessary to remove the
stoppers in the way just mentioned as by simply piercing the cap the vacuum is
relieved and the cap may be lifted off. The rubber ring or other elastic ring
being retained in the groove is not lost as in other vacuum Bottles where the ring
is attached to the stopper, and a continuous expense is thus saved.
We append drawings by which our invention will be clearly understood.
Fig. 1 is a section of the upper portion of a bottle or jar stoppered according to
our Invention; A is the elastic ring fitting into the groove or recess B in Bottle
mouth; C is the dish-shaped stopper resting on and making a joint with the elastic
ring A; D is the spring clip with claws or bent ends E engaging under the rim
outside the bottle mouth.
Fig. 2 is a plan and Fig. 3 a side view of the spring clip D.
Fig. 4 is a plan and Fig. 5 a side view of the dish-shaped stopper C.
Having now particularly described and ascertained the nature of our said
Invention and in what manner the same is to be performed we declare that what
we claim is:
1. The combination of the stopper C with the elastic ring A as and for the
purpose described.
2. The combination of the stopper C and elastic ring A with the spring clip D
as and for the purpose described.
