Improvements in Stoppering Bottles, Jars, Flasks, and like Vessels.
1, ALFRED KEMPSON, of 26, Mark Lane, in the city of London, Merchant, 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 improvements in stoppering bottles, jars, flasks, and like
vessels, the object of the improvements being to allow of the same being closed and
opened quickly and easily..
In carrying out my invention the mouth of the bottle or other vessel to be stoppered
is provided with an internal screw thread, the thread commencing as low as possible
from the opening of the mouth, the interior of the neck from the screw thread to the
mouth being straight that is to say, of the same diameter throughout. The stem of
the stopper for this bottle is provided with a portion of a screw thread not exceeding
one half of a turn the portion of the stem of the stopper above the screw thread being
made to fit loosely in the space of the bottle neck above the screw thread therein so
that the stopper is kept in a vertical position when screwed home. The shoulder of
the stopper is provided with a packing of suitable material such as cork or india
rubber.
In order to enable my invention to be fully understood I will describe the same by
reference to the accompanying drawing in which figure I represents a vertical section
of the neck of the bottle, stoppered according to my invention; figure 2 is an
elevation of the stopper, and figure 3 a plan of the underside of the same. Similar
letters in all the figures represent similar parts.
a, is the mouth of the bottle and, is the internal screw thread with which it is
provided commencing at some considerable distance from the opening of the mouth a;
, represents the portion of the interior of the neck which from the top of the screw
thread b, to the mouth I form straight or of the same diameter throughout; d, is
the stem of my stopper, and e, is the portion of a screw thread not exceeding one half
of a turn with which I provide the same; is the portion of the stopper above the
screw thread, which fits loosely in the space g, of the bottle above the screw thread b
the stopper being by this means kept in a vertical position when screwed home as
shewn in figure 1 h, is the packing of suitable material such as cork or india rubber
with which the shoulder i, of the stopper is provided.
By these means in order to close the bottle the stopper, figures 2 and 3, is inserted
in the mouth a, (figure 1) thereof and a tight joint will be obtained by simply giving

page_text: the stopper a half turn (as shown in figure 1); a half turn in the opposite direction
allowing the stopper to be withdrawn.
Having now particularly described and ascertained the nature of my said invention
and in what manner the same is to be performed I declare that what I claim is :-
1. The improved stopper for bottles, jars, flasks, and like vessels hereinbefore
described and illustrated in the accompanying drawing.
2. Constructing the necks of bottles, jars, flasks, and like vessels as hereinbefore
described so as to adapt them to be closed by my improved stopper as hereinbefore
described and illustrated in figure 1 of the accompanying drawing.
