IMPROVEMENTS IN STOPPERING BOTTLES, JARS AND LIKE VESSELS"
This invention relates to improvements in stoppering bottles, jars and like vessels,
the object of the improvements being chiefly to avoid the necessity of allowing
any material likely to affect the flavour or quality of the contents of the bottle or
other vessel stoppered to come into contact with the said contents.
In carrying out my invention I employ a bottle the interior of the neck of which
is formed with a female screw; the improved stopper consists of a double screw of
suitable hard wood one of the screws being adapted to fit into the mouth of the
bottle; the other screw which has a finer thread projects above the top of the
bottle neck, and serves to receive a cap, or cover of suitable material such as hard
wood, provided with a female screw thread adapted to fit over the herein before
described projecting screw of the stopper and having an elastic washer preferably
of cork.
To stopper a bottle or other vessel according to my improvements, the stopper is
loosely screwed into the mouth of the bottle or other vessel and the cap or cover
is then screwed over the projecting part of the stopper and will press the
elastic washer over the mouth of the bottle or other vessel and form a hermetic
joint.
To open the bottle or other vessel it is merely necessary to turn the cap in the
reverse direction and the whole stopper will be withdrawn

"IMPROVEMENTS IN STOPPERING BOTTLES, JARS AND LIKE VESSELS
"
This invention relates to improvements in stoppering bottles, jars and like vessels
the object of the improvements being chiefly to avoid the necessity of allowing
any material likely to affect the flavour or quality of the contents of the bottle or
other vessel stoppered to come into contact with the said contents
In carrying out my invention I employ a bottle the interior of the neck of which
is formed with a female screw or its equivalent; the improved stopper consists of
a double screw of suitable material preferably hard wood one of the screws being
adapted to fit into the mouth of the bottle; the other screw which has a finer
thread projects above the top of the bottle neck and serves to receive a cap or
cover of suitable material such as hard wood, provided with a. female screw thread
adapted to fit over the hereinbefore described projecting screw of the stopper and
having an elastic washer preferably of cork.
In order to enable my invention to be fully understood I will proceed to describe
the same by reference to the accompanying drawing in which figure 1. represents
an elevation and figure 2. a vertical section of a bottle stopper constructed according
to my invention; figures 3, and 4, are vertical sections of a bottle neck shewing
my improved stopper applied thereto; figures 5, and 6, are an elevation and a
vertical section respectively of a stopper similar to that shewn in the preceding
figures, but with the cap or cover formed in two parts. Similar letters in all the
figures represent similar parts
I will first describe the stopper shewn in figures 1. to 4
'
a, is the neck of a bottle, the interior of which is formed with a female screw
thread as shewn, the screw thread not extending to the top of the mouth of the
bottle, the diameter of the space b, between the top of the screw thread and the
mouth of the bottle being somewhat larger than the diameter of the screw
The improved stopper cousists of a double screw c, d, of suitable material such
as hard wood and is formed with a collar c, between the screw threads c, and d, the
screw c is adapted to fit loosely into the female screw thread in the mouth of the
bottle, the collar e, passing freely into the mouth b; the other serew d, has a finer
thread than the screw c, and screws into the cap or cover f, as clearly shewn in
figure 2; the cap or cover f, is made of any suitable material but preferably of
hard wood; g, is an elastic washer preferably of cork, and which may be cemented
to the bottom or underside of the cap or cover f
To make use of the improved stopper, the cap f, must be partly unscrewed from
its screw d, so as to leave a space between the top of the screw d, and the top of
the female screw thread in the cap f, as shewn in figure 2, the stopper is then
loosely screwed into the mouth of the bottle as shewn in figure 3, until the under-
side of the collar e, éomes against the shoulder h, in the mouth of the bottle which
will prevent the screw c, from entering further into the bottle neck, then by
continuing to turn the cap or cover f, the same will be screwed on its screw d, so
as to bring the elastic washer g, over the mouth of the bottle and thus form a
hermetic joint and at the same time the threads of the screw c, will be drawn up
against the female screw thread in the neck of the bottle so that the stopper will
be held firmly in its place as shewn in figure 4
To open the bottle it is merely necessary to turn the cap or cover f, in the
reverse direction and the whole stopper will be withdrawn. Before again using

page_text: the stopper it will be advisable to "partly unscrew the cap or cover f, from its
screw d, as hereinbefore described
The stopper shewn in figures 5 and 6, is substantially the same as that shewn in
figures 1 to 4, except that the cap or cover f, is formed in two parts with an elastic
washer i, between them. By thus forming the cap in two parts a tighter grip on
the screw d, is obtained when the stopper is screwed down, the upper part of the
cap forming a lock nut so that in the event of the screw. c, sticking in the neck
from any cause (such for example as from the nature of the contents of the vessel)
the cap f, will be prevented from turning on its screw d, when withdrawing the
stopper.
Although I have described my invention as applied to a bottle it is equally
applicable to jars and like vessels.
It will be obvious that instead of forming the neck of the bottle or other vessel
with a female screw thread it may be formed with vertical grooves or slots and a
shoulder, in which case the stopper instead of being formed with the screw thread c,
would be formed with a number of projections corresponding with the vertical
grooves or slots in the bottle neck, the projections and grooves forming what may
be termed a bayonet joint
Having thus described my invention and the manner of performing the same
what I claim is.―
Firstly. A stopper for bottles, jars and like vessels consisting of a coarse screw
(or its equivalent) for fitting into a corresponding female screw (or its equivalent)
in the mouth of the bottle, and a fine screw for receiving a screw cap or cover
provided with an elastic washer, all arranged and operating as herein before
described
Secondly In a stopper for bottles, jars, and the like the combination of the
coarse screw c, collar e tine screw d, screw cap f, and washer g, as and for the
purposes herein before described and represented in the accompanying drawing.
Thirdly The combination with a bottle neck provided with a female screw
thread (or its equivalent) a space b, and a shoulder h, of a stopper of the construction
hereinbefore described and represented in the accompanying drawing.
Fourthly The stopper for bottles, jars and like vessels having a cap or cover in
two parts as herein before described and shewn in figures 5 and 6 of the
accompanying drawing
Fifthly The manufacture and use of the improved stoppers for bottles, jars
and like vessels substantially as hereinbefore described and represented in the
accompanying drawing
In witness whereof I the said Alfred Kempson have hereto set my hand and
seal this third day of January in the year of our Lord One thousand eight hundred
and eighty four
