COMPLETE SPECIFICATION.
Improvements in Stoppering Bottles, Jars, or other Containers.
We, FRANZ HOUBEN, Chemist, Mannheim, H 10-16, and JOHANNES WOLLEN-
SCHLÄGER, Merchant, Mannheim, H. 7-4., both 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:-
Our invention relates to an exceedingly simple, practical and clean stopper
which effects air-tight closing without employing any metallic parts whatever.
In the annexed drawing.
Fig. 1, is a horizontal view of the bottle-neck;
Fig. 2, a vertical cut of the bottle-neck and stopper;
Fig. 3, a horizontal cut of the stopper according to A-B of Fig. 2.
Figs. 4 & 5 show a different arrangement.
Figs. 6 & 7 give front and side views of the stopper, without the rubber ring.
This bottle or jar, which may be made of glass, porcelain or other suitable
material, bears, inside its discharge passage and at less than half an inch from
the rim, two semi-circular inwardly-projecting ledges a a with openings between
them. The lower portion c of the stopper-body is adapted to slide through said
ledges a a and has two projecting lugs did which can pass through the open-
ings 5 b. When the projecting lugs dare under the openings bb the stopper can
be revolved through an angle of 90 deg., thereby bringing the projecting lugs dd
of the stopper under the ledges a a.
A cushion ring e is arranged to lie between the shoulder of the stopper and
the ledges d d and forms an air-tight joint.
The stopper may be made of any suitable material and the ring e, of rubber,
asbestos, cork or other like substance.
If the contents of the bottle should become heated, the ring e acts as a valve
operating from the interior to the exterior, the air or vapor making its escape
The atmospheric
through bb the ring e and the bottle neck into the atmosphere
pressure then bears upon e, exerting a downward force on the neck, thereby
making it impossible for the air to enter the bottle from the outside.
Bottles of this description may be employed with advantage for preserving,
sterilising or Pasteurising all kinds of liquids. fruits and the like.
The inwardly-projecting ledges a a on the bottle-neck may also be reduced in
size down to the size of the projecting lugs a¹ (Fig. 4). To correspond therewith,
the projecting lugs d on the stopper-body are made larger and larger, finally
taking the shape of the projections (Fig. 5). To facilitate the escape of the air,
it is advisable to provide the portion of the stopper above the projecting neck-
bottle ledges with an oblique channel ƒ (Figs. 6 & 7).
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:-
A stopper for bottles, jars, and other containers characterized by having, close
to the rim of the bottle, two semi-circular inwardly projecting ledges a a, in the

page_text: spaces bb between which the projecting lugs d d of the stopper can be passed for
the purpose of revolving the stopper 90 deg. and bringing the projecting lugs d d
under the inwardly-projecting ledges a a whilst there is arranged in the bottle
neck between the said ledges aa and the stopper-body can elastic ring e which
acts as an exteriorly opening valve for the escape of vapor from the bottle, and
on the other hand is pressed down and made air tight by the weight exerted by
the atmosphere on the bottle-neck, substantially as above described and as shown
in the annexed drawing.
