Improved Stoppering Device for vessels.
J, HERMANN CARL HARTZ, of 9, Steckelhorn, Hamburg, German Empire,
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 :-
The object of the present application consists essentially of a stoppering device
for vessels of all kinds by means of which an easy insertion and withdrawal of the
stopper can be effected and in which the airtight closing of the neck of the vessel
is a perfectly reliable one whilst the mechanism requisite is of a very simple nature.
The same is applicable to all sorts of vessels and is also very suitable for transport
purposes and suffers little injury in use.
Referring to the accompanying drawings, the invention is shown in
Figure 1 in longitudinal section through the stoppering device, and in
Figure 2 in view firmly fixed in position in the neck of the vessel.
The stoppering device consists essentially of two stoppers a b of cork or other
elastic material which are penetrated by a screw c ending above in a ring. This
ring is constructed with a swivelling arrangement revolving around the bolt c¹ in
order to enable the vessels to be conveniently placed upon each other which is of
advantage when in transit. Between the stopper a and the ring c there is placed a
closing disc d provided with an elastic washer in the shape of a ring d', which disc
is covered by a little plate e. At the lower part of the stopper 6 there is a plate f
attached, the points of which g engage in the stopper so as to hold it fast. To this
plate f there is attached an envelope provided with a matrix i, in which the
screw e moves when the two stoppers are screwed together, whilst the screwing out of
the same from out of the matrix is prevented by means of the disc k. The said
envelope can be closed by means of a cap which prevents any fragments from
the two stoppers caused by the friction of the screwing in or out of the screw c,
from falling into the fluid in the vessel. At the points in the neck of the vessel at
which the stoppers would press on being screwed together, the neck can be
provided with a slight widening, in order that thereby a better closing and a firmer
securing of the stopper may be effected. When the stoppering device is inserted
in the neck of the vessel (Figure 2) and the screw c turned, the two elastic
stoppers a and b are pressed together and are thereby forced outwards against the
neck of the vessel so that an unquestionably air tight closing of the vessel is
secured, whilst when the screw c is turned back the stoppering device can be easily.
withdrawn from the vessel.
The above description makes clear the advantages of the closing device set forth
in the commencement of the specification and the same distinguishes itself by its
great security from previous arrangements.
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 improved closing device for vessels of all kinds characterised by having one
