PROVISIONAL SPECIFICATION.
Improvements in Closing Bottles and Jars.
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:-
Our improvements have reference to that class of glass bottles or jars which are
used for preserving or bottling milk, soup, fruit or other articles, and provide a
clean simple and efficient method of hermetically sealing such bottles or jars.
According to our invention we form a recess or groove in the interior of the
bottle mouth, and in this recess or groove we place an elastic ring of suitable shape.
We then take a stopper preferably made of glass to fit inside the bottle mouth. This
stopper may be circular or other suitable shape on its under side so as to effectively
make a joint with the rubber ring. The upper portion of the stopper may be
round or any other suitable shape.
After the bottle or jar has received its contents and the elastic ring and
stopper have been placed in their proper position, a movable clip or holder is
passed over the stopper. This clip or holder may have claws or bent ends or may
otherwise be arranged so as to fasten itself on the bottle mouth. The clip is made
of spring steel or other yielding material to allow the escape of the air from the
bottle by the pressure of the steam generated within the bottle 'during the process
of cooking or heating the contents.
As the bottle and its contents are allowed to cool the steam generated within the
bottle condenses and produces a vacuum and the pressure of the atmosphere assists
the spring clip or holder in forcing the stopper into airtight position, when the
clip or holder may be removed. The air may also be exhausted from the bottle
by means of an air pump or in any other suitable way.
By making our improved stopper of glass there is no metallic substance of any
kind coming in contact with the contents of the bottle or jar. Our invention admits
of the stopper being made of globe or half globe shape, of conical form, or of a
variety of other shapes which may be adapted for forming an airtight joint with the
elastic ring and for engaging with the spring clip or holder.

in what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement
a
Our improvements have reference to that class of glass bottles or jars which are
used for preserving or bottling milk, soup, fruit, or other articles, and provide
clean, simple, and efficient method of hermetically sealing such bottles or jars.
According to our invention we form a recess or groove in the interior of the
bottle mouth, and in this recess or groove we place an elastic ring of suitable shape,
either of india rubber or other suitable material. We then take a stopper preferably
made of glass to fit inside the bottle mouth. This stopper may be circular or
other suitable shape on its under side so as to effectively make a joint with the
rubber ring. The upper portion of the stopper may be round or any other
suitable shape.
After the bottle.or jar has received its contents and the elastic ring and stopper
have been placed in their proper position, a movable clip or holder is passed over
the stopper. This clip or holder may have claws or bent ends or may otherwise be
arranged so as to fasten itself on the bottle mouth. The clip is made of spring
steel or other yielding material to allow the escape of the air from the bottle by
the pressure of the steam generated within the bottle during the process of cooking
or heating the contents.
As the bottle and its contents are allowed to cool the steam generated within the
bottle condenses and produces a vacuum, and the pressure of the atmosphere
assists the spring clip or holder in forcing the stopper into airtight position, when
the clip or holder may be removed, or the clip or holder may when desired be
allowed to remain on the bottle mouth as an additional security to the stopper
being kept in airtight position. The air may also be exhausted from the bottle by
means of an air pump or in any other suitable way.
By making our improved stopper of glass there is no metallic substance of any
kind coming in contact with the contents of the bottle or jar. Our invention admits
of the stopper being made of globe or half globe shape, of conical form, or of a
variety of other shapes which may be adapted for forming an airtight joint with
the elastic ring and for engaging with the spring clip or holder.
Our invention will be clearly understood by the annexed drawings. Of these
drawings Fig. 1 is a section of the upper portion of a bottle or jar stoppered with
one form or shape of stopper applicable to our invention., A is the stopper; B the
elastic ring.; C the clip or holder passing over the stopper A and having claws or
bent ends E engaging under the outside rim of the bottle mouth; D is the bottle
or jar.
Fig. 2 is a side view and Fig. 3 a plan of the clip or holder C.
Fig. 4 is a sectional view and Fig. 5 a plan view of stopper A, and illustrates
one form of stopper applicable to our invention.
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 :-
The combination of the stopper A elastic ring B and spring clip C as and for the
purpose described.
