COMPLETE SPECIFICATION.
Improved Double-closing Stopper for Bottles and other Receptacles.
I, JULIUS SALOMON, of Schlossplatz of Pankow near Berlin, in the 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 :-
This invention relates to an improved stopper for bottles and other receptacles,
effecting, by means of a closing cap coming in contact with the upper edge of the
bottle or other receptacle and at the same time pressing with its edge on a ring
provided on an outer shoulder of the neck of the bottle or other receptacle, a
double closing of the bottle or other receptacle without it being necessary to turn
the stopper. By this device it is possible to use cork as material for tightly closing
the bottle or other receptacle, which material, from a hygienic standpoint, is far
superior to india rubber, although it cannot be employed where the stopper has to
be turned or screwed down.
As against other materials used for stoppers, such as leather and the like, cork
has the advantage that it is somewhat elastic and can therefore also be used for
closing vessels intended for holding gaseous or gas-generative liquids.
I will now describe my invention with reference to the accompanying drawing in
which :-
Fig. 1 is a vertical section of a bottle neck provided with the improved double
stopper.
Fig. 2 shows a part of the bottle with the stopping device opened.
The stopper consists of a cap a made of porcelain, metal, or other suitable
material, which cap is provided with a rim, flange, or projecting edge a' and adapted
to be secured to the neck of the bottle by means of suitable well known device, for
instance as shown in the drawing.
The head or mouth piece of the bottle has a shoulder 6' on its outer side for
receiving a packing ring c preferably made of cork, which ring c is stretched over
the slightly-conical lips of the bottle head. A disc d made of cork or other suit-
able material is placed inside the cap a. When the cap a is closed the disk d
pressing against the lips of the mouth 62 effects the first closing, and the projecting
edge a of the cap a pressing against the ring c simultaneously effects the second or
double closing of the bottle. The diameter of the cork ring c and cork disk d are
preferably such, that the latter is cut out of the disk of cork when cutting or
stamping out the ring c; thus all waste of material is avoided.
C
Having now particularly described and ascertained the nature of this inven-
tion and the manner in which the same is to be performed, I declare that what I
claim, is :-
1. An improved double closing stopper for bottles and other receptacles
consisting of a cap (a) whose inner disk (d) presses against the lips of the
bottle neck whose flange or projecting edge (a¹) presses against a packing
ring (c) provided on an outer shoulder (6¹) of the bottle neck, substantially as
described and shown in the drawing.

consisting of an outer shoulder. (61) on the neck of the bottle for receiving an outer
packing ring, substantially as described and shown in the drawing.
