COMPLETE SPECIFICATION.
Improvements in and relating to Stoppers for Bottles, Jars, and
similar Vessels.
CARL HANISCH, of Lautenthaler Strasse, Seesen a/ Harz, in the Kingdom of
Prussia and German Empire, Brewer, do hereby declare the nature of this inven-
tion, 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 stoppers which may be employed for closing bottles jars
and other similar vessels, and its object is the construction of a simple and effective
stopper which may be produced at a very low cost.
The stopper constructed according to this invention is illustrated by the
accompanying drawings and will be hereinafter described with reference thereto.
In these drawings,
Figure 1 represents an elevation of the neck of a bottle to which the stopper is
applied, the stopper being open.
Figure 2 is a similar view with the stopper closed.
Figure 3 is an end elevation of the stopper.
Figure 4 is a vertical section of the bottle neck.
Figures 5 and 6 are representations of the tools which may be employed for
opening and closing the stopper.
I have shewn in the drawings, and will hereinafter describe the stopper as being
applied to a bottle only, but it will be understood that it may be similarly applied
to jars, wide mouthed bottles, and other similar vessels, the difference being one of
dimensions only.
The stopper consists essentially of the cap K, which is cut or stamped out of
springy sheet metal such as steel or brass. The central portion of the cap, d, is
shaped to cover the mouth of the vessel, and the two wings 11, are bent at right
angles therewith and parallel with each other or as may be required by the shape of
the mouth of the vessel which it is to close. At the extremities of the wings there
are formed or secured the two pins or projections ss, which are best produced by
bending the tips of the wings at right angles inwards as shewn by Figure 3.
Just below, and outside of the mouth of the vessel, there are formed two diametric-
ally opposite L-shaped slots vv, in, but not through, the thickness of the material.
In applying the stopper to the bottle, the wings are slightly opened outwards so
that the points ss may be inserted into the vertical portions of the slots i v. The
stopper is then pressed downwards until the points reach the bottom of the slot,
when the stopper is turned through part of a revolution causing the points to enter
the horizontal portions of the slots. The stopper is thus held by a bayonet lock,
and cannot be released without first rotating the stopper in the opposite direction.
Owing to the spring pressure of the wings of the stopper, the points ss are firmly
held in the slots in every position.
It will be found unnecessary to remove the stopper from the vessel in order to
abstract its contents, as, when the stopper is lifted, it may be tilted sidewise, as
indicated by Figure 1, quite clear of the neck if desired, or only partly clear
as shewn.
When it is desired to obtain a hermetical joint between the stopper and the
mouth a of the vessel, a suitable elastic or compressible substance is introduced
between the part d and the mouth. Cork or indiarubber may be suitably used for
this purpose, and may be cemented or riveted on the underside of d, as shewn at e,
Figure 3, or it may be a separate and independent pad or cushion, of a disc or
annular form, laid or cemented upon the mouth of the vessel and held between it
and the part d.

page_text: Owing to the fact that a tight joint can only be secured by exerting pressure, it
has been found advisable to devise tools by means of which the necessary pressure
may be exerted and released in opening and closing the vessel. The tool to be
used in closing the vessel is illustrated by Figure 5. It consists of two arms hinged
to the connecting piece g. One of the arms b is shaped like the letter J, and the
other, f, is flat with the two pins c c secured on its inner face. To use the tool, the
stopper being assumed to be in the position represented by Figure 1, the arm b is
placed with its bent portion around the lower part of the neck of the vessel. The
arm is then folded over the stopper, bringing the part d into a horizontal position
with one of the pins con each side of it. The two arms being then pressed together,
the stopper is forced downwards until the points ss reach the horizontal part of the
slot v, when the tool is turned horizontally and the points are caused to enter the
horizontal portion of the slot through the engagement of the pins cc with the stopper,
which compel it to follow the turning motion of the tool.
The tool for opening the vessel is shewn by Figure 6, and consists of a piece of
strong wire bent and closed to produce the handle h and the two points u.
It may
of course be forged or stamped to a corresponding form, but it is preferred to
construct it of strong steel wire. To use the tool, the points u are inserted under
the cap d, one on each side, and the stopper is thereby turned until the points $ 8
enter the vertical parts of the slots when the stopper may easily be lifted.
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 :-
1. A stopper for bottles jars and other like vessels, constructed and arranged
substantially as herein before described and as illustrated by the accompanying
drawings.
2. A stopper for bottles jars and other similar vessels, consisting of a cap d
having two wings and two points s s engaging with two L shaped slots formed
in the substance of the neck or upper part of the vessel, constructed substantially
as hereinbefore described and as illustrated by the accompanying drawings.
3. A stopper for bottles jars and other similar vessels, consisting of a cap d
having two wings 11 and two points ss engaging with two ✓ shaped slots formed in
the substance of the neck or upper part of the vessel, and a soft elastic or com-
pressible substance between the cap and the mouth of the vessel, constructed
substantially as hereinbefore described and as illustrated by the accompanying
drawings.
