Improvements in or relating to Stoppers for Bottles or the like.
We, EMIL STIERLING and WILLIAM GÖTZKY, Merchants, of Werder No. 9, Bruns-
wick, 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:—
In most of the bottle closing devices in ordinary use india-rubber is used for
the purpose of effecting a tight fit. These devices, however, suffer from the draw-
back that the liquid contained in the bottles often suffers in value, by acquiring
a taste and smell from the india-rubber used in them, owing to the chemical
action which the liquid produces on the india rubber. In consequence of this
drawback merchants and others have in many cases gone back to the old system
of closing bottles by means of cork stoppers. But however excellent the latter
may be as regards its effect, its application is clumsy and impracticable as com-
pared with india rubber closing devices which are modern and easily handled.
This invention relates to a closing device for bottles and the like which combined
the good qualities of the simple cork stopper and the advantages characterizing
the modern indiarubber closing devices. The device consists essentially of a
cylindrical piece or plug of cork which is pressed into a recess of a porcelain,
composition or other knob or head which recess is conically widened towards the
interior which cork is pressed into the neck of the bottle-preferably conically
shaped-provided in the interior with an annular shoulder.
In the accompanying drawing the closing device is represented in two forms.
The cork is fixed in the head b. The part projecting from the head is cylin-
drical. When pressed into the neck c of the bottle, Figure 2, it is somewhat
compressed at its lower end, and its lower edge being closely pressed against
the shoulder provided for that purpose in the neck of the bottle, a reliable and
air-tight closing is effected.
The modification of the device as represented in Figs. 3 and 4 differs from
that represented in Figs. 1 and 2 in so far that the upper part of the cork a is
provided with a flange projecting around the cylindrical part of the cork and
forming a kind of shoulder the lower surface of which when the stopper is in-
serted, comes against the top edge of the neck of the bottle, covering the same
against dust and the like and increasing the tight closing effect of the stopper.
The stopper can be easily removed from the neck of the bottle and the danger
of breaking off of the cork is minimised.
This closing device is characterized by great durability and especially by
simplicity, and the fact that it is easily retained in the bottle.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed, we declare that what
we claim is:-
1. A stopper for bottles or the like consisting of a cork plug (which is alone
used as the stoppering material) secured in a porcelain or other head and adapted

page_text: to be inserted into a neck of the receptacle to be closed and pressed against a
shoulder in the latter substantially as described.
2. A stopper for bottles or the like of the kind described in which the upper
part of the cork has a flange forming a surface which will close against the edge
of the neck of the receptacle when the cork is inserted protecting the edge against
the entrance of any kind of impurity and increasing the stoppering effect of the
device substantially as described.
3. The complete stopper for bottles or the like substantially as described and
illustrated in Figures 1 and 2 or in Figures 3 and 4 of the accompanying draw-
ings.
