Improvements in Stoppers for Bottles, Jars, and other Receptacles.
I GEORG MICHAELSON, Manufacturer of Mechanical Patent Cork Stoppers of
33 Unter den Linden, Berlin, in the Empire of Germany 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 for improvements in stoppers for bottles jars and other receptacles
has for its object to obviate the disadvantages appertaining to the use of stoppers
having a disc or ring of rubber as the impervious material. As is known the
rubber stoppers have the inconvenience of dissolving in the contents of the bottles
sufficiently to impart thereto a slight smell or taste of the rubber, and furthermore
they are not looked upon favourably on account of the rubber becoming soft and
sticky at high temperatures.
In a stopper constructed according to this invention cork is used as the impervious
material for stoppers for bottles and other receptacles and this material does not
possess the before mentioned disadvantages, is very cheap, and can by the employ-
ment of a high degree of temperature be easily sterilised or cleansed.
In the accompanying drawings
-
Figure 1 is a view of the stopper, fitted to the neck of a bottle, constructed
according to this invention.
Figure 2 is a top view of the same and
Figure 3 is a vertical section through the stopper.
The stopper shown as an example fitted to a bottle consists essentially of a cap a
of metal, porcelain, celluloid, or other suitable substance and which is provided
with a projecting rib which is turned inwards so as to form a slightly conical
opening in which fits the cork disc c forming the stopper. The cork disc presses on
the top of the bottle neck d so that neither the bottle neck nor the disc of cork nor
the cap carrying the disc need be made to a special shape as in the case of the
known stoppers with porcelain top and rubber lining which are inserted in suitably
constructed bottle necks.
In order to make the stopper a mechanical one, the cap is by means of the
hinge connected to one end of a link e and is retained over the mouth of the
bottle by a second hook shaped link k fitting over a projection g on the other side
of the cap a.
The links e and h can be attached to the neck of the bottle by the
wire i fitted round it in any known and suitable manner.
The pressing down and closing the stopper cap can also be effected by any other
suitable arrangement.
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 :-
A stopper for bottles jars and other receptacles in which the closing is effected
by a cap a fitted in its slightly conical cavity with a cork disc c which is pressed by
suitable arrangement on the mouth of the bottle so that the closing is independent
of the shape of the mouth or neck of the bottle substantially as described.
