PROVISIONAL SPECIFICATION.
Improvements in Means for Hermetically Closing Bottles, Jars, and
like Receptacles, and for Opening the same.
I, ALOIS TSCHURTSCHENTHALER of Bozen in the Empire of Austria, Preserver
do hereby declare the nature of this invention to be as follows :-
This invention relates to a means of closing or sealing bottles, jars and like
receptacles, and is effected by a lid or cap inserted on the mouth of the receptacle,
the depending flange of which lid effects an hermetic closing in connection with an
indiarubber ring placed in an annular groove or flute in the upper part of the neck
of the receptacle.
As against known means of sealing receptacles which are hermetically closed by
indiarubber rings placed on their mouths, the present device offers the advantage
that it is not necessary to rarely the air in the receptacle for effecting an hermetic
sealing, consequently, the heating of the contents of the receptacle does not interfere
with the efficiency of this closing device.
This device is constructed and operated as follows:-
A groove or flute, in which an indiarubber-ring is laid, encircles the upper part
of the neck of the receptacle. When the lid is put on, the indiarubber ring is
compressed by the depending flange of the lid, which has a less inner diameter than
the ring, and, consequently, an hermetic sealing effected.
It will be evident that the lid cannot be pressed so far, that the under surface of
its crown comes in contact with the edge of the receptacle, unless the surplus air
can escape. To meet this requirement, according to this invention, a hollow or
channelled rod is provided, adapted for insertion from underneath between the wall
of the receptacle neck and the indiarubber ring. That air which must escape
before the lid can be put on, therefore, passes out of the receptacle, through or
along the channel of said rod; after withdrawal of this channelled rod, the receptacle
is hermetically closed.
The said rod can also be employed to admit air into a receptacle required to be
opened and thus facilitates the taking-off of the lid. This latter method of opening
is recommended where the receptacle when closed was made hot (by reason of
contents being hot when filling &c.) and consequently after cooling the rarefied air
in such receptacle has caused the lid to be very firmly pressed on the mouth of the
receptacle.

COMPLETE SPECIFICATION.
Improvements in Means for Hermetically Closing Bottles, Jars, and
like Receptacles, and for Opening the same.
I, ALOIS TSCHURTSCHENTHALER, of Bozen, in the Empire of Austria, Preserver,
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 a means of hermetically closing or sealing bottles, jars
or like receptacles, and is effected by a cap or lid put over the mouth of the

page_text: receptacle, the flange of which lid, by pressing against an indiarubber or caoutchouc
ring placed in a groove or flute in the upper part of the neck of the receptacle,
causes an hermetic closing.
As against known methods of hermetically sealing such receptacles by means of
indiarubber rings placed on their mouths, the present device offers the great
advantages of being exceedingly simple, and also that for effecting the hermetical
closing, it is not necessary to exhaust the air present in the receptacle; consequently,
the contents of the receptacle need not be heated, as is the case with the devices at
present in use.
I will now describe my invention with reference to the accompanying drawings,
in which :-
Fig. 1. is a vertical section of a bottle provided with the improved closing device,
and showing the lid on, and
Fig. 2. is a similar view showing the lid in elevation and removed from the
receptacle.
Fig. 3. is a suitable device for opening the receptacle.
a is a groove or flute encircling the neck of the receptacle, in which an india-
rubber or caoutchouc ring is placed.
When the lid is put on, the indiarubber ring 6 is pressed against the walls
of the bottle neck by the flange of the lid c, and thus an hermetic closing is
effected.
It will be evident that the lid c cannot be pressed down until the under surface
of its horizontal plate comes in contact with the upper edge of the receptacle, unless
the surplus air can escape. To meet this requirement, the hollow or grooved rod d
adapted for insertion, from underneath, between the wall of the receptacle-neck, and
the indiarubber ring b, is used in the manner shown in Fig. 2; air which must
escape when the lid is being put on, therefore, passes out of the receptacle, through
or along the hollow or groove in the rod d.
The rod d may also be used for admitting air into the receptacle when it is
required to open same, and thus the taking off of the lid is greatly facilitated. This
latter method is essentially recommended in cases where the receptacle or its
contents had been heated when putting on the lid, so that the rarified air has pressed
the plate of the lid tightly on the mouth or edge of the receptacle.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, 1 declare that what I
claim is :-
:-
1. Improved device for hermetically closing bottles, jars and the like receptacles,
in which an indiarubber or caoutchouc ring (6) placed in an annular groove or
flute (a) is pressed against the walls of the receptacle neck by the flanges of a lid
or cover (c) and thus an hermetic sealing is effected, substantially as described and
shown in the drawing.
2. An improved means of hermetically closing bottles, jars or the like receptacles
as characterized by Claim 1, in which when closing or opening the receptacle a
hollow or grooved rod (d) is inserted between the indiarubber ring and the neck of
the receptacle for allowing the air to enter or escape, substantially as described and
shown in the drawing.
