Improvements in the Method of Stoppering and Covering the Mouths
of Bottles and other Vessels.
I THEODORE Bernard BirnbaUM of 33 London Wall in the City of London.
India Rubber Manufacturer, do hereby declare the nature of this invention to be
as follows:-
My invention consists of an india rubber thimble or cap of suitable shape, having
a rolled or otherwise thickened edge, such thimble or cap being stretched over the
neck or mouth of any bottle or other vessel, the rolled or thickened edge gripping
the lip or neck of the bottle or other vessel and by this means the mouth or neck
of such bottle or other vessel is hermetically sealed without the aid of a cork or
stopper, and any cork or stopper in such bottle or vessel is held in its place.
The thimble or cap may be made of india rubber or other suitable elastic sub-
stance and the rolled or otherwise thickened edge may be made by any usual
method.
.
The use of this invention will avoid the present practice of securing corks or
stoppers in bottles by tying skin or kid over them; it will prevent evaporation and
it will serve the purpose of a cork or stopper by securing the mouth of any bottle
or vessel.

COMPLETE SPECIFICATION.
Improvements in the Method of Stoppering and Covering the Mouths
of Bottles and other Vessels.
I THEODORE BERNARD BIRNBAUM of 33 London Wall in the City of London
India Rubber Manufacturer 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 :-
The usual method of covering the mouths of bottles or other vessels and securing
corks and stoppers therein or covering the mouths of bottles or other vessels where
a cork or stopper is not employed is, by placing skin kid or paper over the cork or
stopper or mouth of the bottle (as the case may be) and securing the same by tying
string or other material below the mouth of the neck of such bottle or other vessel.
By this method considerable time is involved in the process of attaching such
covering and evaporation and leakage is often permitted by reason of the porous
nature of the material used and the sometimes insecure nature of the tying and
consequent loosening of the cork or stopper. These defects are obviated by the
use of my invention. To enable the same to be properly understood I will proceed
to describe the same with aid of the accompanying drawings:-
Figure 1, a detailed view of my invention.
Figure 2, illustrates its application to a bottle.
Figure 3, corresponding view to a bottle without cork or usual stopper.
Figure 4, corresponding view to a jar without cork or usual stopper.
(a) represents a thimble or cap made of an elastic material and of any size or
shape suitable to be stretched over the mouth of the vessel to be covered. To
assist the grip and the retaining of the cap or thimble in its place and to prevent
the edge of the same from tearing, it is rolled up or thickened as at (6). To

page_text: prevent the thimble being lost it may be made with an eye or button (c) at top or
other convenient place to which to attach a cord (d) one end of which which may
be secured to an elastic ring (e) to slip over the neck of the bottle before the
thimble is put on.
For further security. against possible evaporation and more especially when the
bottle or other vessel contains liquid of a very volatile nature the ring (e) may be
drawn over the neck of such bottle or other vessel, gripping the thimble immediately.
above the rolled or thickened edge (b) and below the mouth of the bottle thus
affording additional grip and rendering evaporation or leakage impossible. This
ring (e) when not in use in this way may be drawn down the neck of the bottle as
described.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is,
An elastic airtight covering for the mouths of bottles or other vessels substan-
tially as and for the purposes hereinbefore described and illustrated by the
accompanying drawings.
