Improvements in Closing or Stoppering Bottles, Jars, and the like.
We, THOMAS CASSIENET PALMER, WILLIAM JOHN FRASER, FRANK HAZEL FRASER
and LESLIE MCGREGOR FRASER, trading as W. J. Fraser & Co., of 98, Commercial
Road, East, in the County of London, Engineers, do hereby declare the nature of
this invention to be as follows:-
This invention relates to vacuum closing or stoppering of bottles, jars and like
vessels such as are used for containing fruits, preserves, pickles, drugs and the like
the improvements having mainly for object to dispense with the necessity of employing.
a specially constructed bottle or jar as has hitherto been necessary with the vacuum,
closing of bottles and jars.
In carrying out our invention we employ a conical or taper stopper or plug.
with or without a flange at the upper end. Our stopper is provided with a ring.
of any suitable flexible material to form a tight joint. between the side of the stopper
and the bottle.
The closing of the bottle or other vessel by our improved stopper is effected in the
usual manner or in cases where the contents of the bottle would be injuriously
affected by heat the bottles may be placed in a closed chamber from which the air is
exhausted.

Improvements in Closing or Stoppering Bottles, Jars, and the like.
We, THOMAS CASSIENET PALMER, WILLIAM JOHN FRASER, FRANK HAZEL FRASER,
and LESLIE MCGREGOR FRASER, trading as W. J. Fraser & Co., of 98, Commercial
Road East, in the County of London, Engineers, 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 vacuum closing or stoppering of bottles, jars and like
vessels such as are used for containing fruits, preserves, pickles, drugs and the like,
the improvements having mainly for object to dispense with the necessity of employing
a specially constructed bottle or jar as has hitherto been necessary with the vacuum
closing of bottles and jars.
In carrying out our invention we employ any ordinary or straight necked bottle
and a conical or taper stopper or plug with or without a flange at the upper end.
Our stopper is provided with a ring of any suitable flexible material to form a tight
joint between the side of the stopper and the bottle by the gradually increasing
pressure of the conical stopper.

page_text: To enable our invention to be fully understood we will describe the same by
reference to the accompanying drawing, in which :-
Figure 1 is an elevation.
Figure 2 a plan of the underside, and
Figure 3 a vertical section on the line 3-3 of Figure 2 of the stopper we employ
for carrying out our invention:
Figure 4 is a section of an ordinary bottle or jar shewing the stopper applied
thereto.
As will be seen by the drawing the stopper consists of a conical or taper plug a
formed with a flange b and can be advantageously stamped out of thin sheet metal;
c is the ring of india-rubber or other suitable elastic material placed on the lower
end of the conical plug a.
The closing of the bottle or jar by means of this stopper is effected in any usual
manner, that is to say, the bottle d being filled, the plug a with its elastic ring c
is placed in the mouth of the bottle; the stopper being held in this position by a
spring clip, a weight, or other suitable device. The air is then expelled from the
bottle by heat or otherwise, so that the stopper is maintained in its position as
shewn in Figure 4 by atmospheric pressure in the usual manner, the elastic ring b
being compressed between the taper plug a and the straight side of the bottle and
forming a tight joint as shewn in Figure 4 and the flange b resting on the top of the
bottle.
In cases where the contents of the bottle would be injuriously affected by heat
the bottles may be placed in a closed chamber from which the air is exhausted or
connected direct to a vacuum pump having a suitable connection.
The bottle is opened in any usual manner such, for example, as by perforating
the stopper.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is :-
The vacuum closing or stoppering of ordinary or straight necked bottles, jars and
the like by means of a taper stopper or plug provided with an elastic ring in the
manner and substantially as hereinbefore described and illustrated in the accompanying
drawing.
