COMPLETE SPECIFICATION.
Improved Means for Stoppering or Closing Aerated-water-bottles
and similar Receptacles.
We. JOHANN NADLER. Engineer, and STEFAN OBERMAYER, Gentleman, both
of I Weihburggasse 12, Vienna, in the Empire of Austria, 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 means for stoppering or closing aërated-water-bottles
and other vessels containing gaseous liquids, all the parts intended to come in contact
with the liquid being manufactured from materials perfectly harmless to health, such
as glass, ceramic materials, indin-rubber or inalterable metals.
In carrying out our invention we employ a plug freely movable in a syphon-head
between the syphon-tube and the discharge-tube, the said plug being pressed by the
pressure of the gas against the opening of the discharge tube, whereby the tight
closing of the latter is effected. In order to empty the contents of the receptacle
the plug is moved from its seating by pressure by the means hereinafter described.
The connection of the stoppering or closing device forming the head of the
bottle, with the bottle or the receptacle itself, can be effected by means of a
connecting device, without the application of screws, or by cementing the said head
to the neck of the bottle.
In the accompanying drawing,
Figure is a vertical sectional view of the mouth of a bottle or receptacle stoppered
according to our invention, the stoppering device being shewn closed and connected
with the bottle or receptacle by means of a coupling contrivance:
Figure 2 is a similar view but shewing the stoppering device open and connected
with the bottle by cementing the upper part of the bottle in the stoppering or
closing device:
Figure 3 is a horizontal section on the liner, Figure 1, through the
coupling contrivance connecting the stoppering or closing device with the bottle:
Figure 4 is a horizontal section on the line y Figure 1:
Figures 5 and 6 are perspective views of the closing-plug and of a socket herein-
after described upon which bears the syphon-tube.
As shown in Figures 1 and 2, a plug B is arranged inside the hollow space of the
closing-device A, connecting the syphon-tube a with the discharge-tube a'; this
plug is kept pressed with its upper surface against a correspondingly-shaped seat a²
by the pressure of the gas contained in the liquid, and in this manner closes the
passage through the device into the receptacle between a and a'and retains the liquid
in the receptacle. The plug B is provided on its circumference with ribs b
(Figures 1 and 5), the said ribs serving to guide the plug in the hollow space of the
device A and, at the same time, allowing the liquid to pass through the grooves
left free between these ribs.
The plug B can, however, be made of any other form suitable for the same
purpose, for example, it can be provided with holes or recesses, or the hollow space,
in which the plug is guided, can be suitably enlarged or it can be provided with
lateral channels. In any case the arrangement must be such that the space
remaining between the plug and the sides of the chamber shall not be too large,
otherwise during the filling and more especially during the emptying of the bottle the
plug would beat against the said sides.
Above the plug B and independent of the same is arranged a rod or piston c,
which, on its upper end is provided with a knob C protruding from the closing-

page_text: the
device upwards; this knob when pressed down removes, by means of the rod
plug B from its upper seat. The downward stroke of the rod e is limited by a pinc
fixed in the side of the upper part of the device and extending into a recess c¹ in
the knob C.
To allow the rod to work air-tight we provide tubular pieces d, d' of india-
rubber or other suitable elastic material. The tube d serves as a packing and as a
spring whilst the tube d' only serves to increase the tightness of the packing. The
packing may, however, consist of only one or of more than two pieces of tube.
The syphon-tube a is placed in a socket E closing the bottom aperture of the
chamber containing the plug B, and provided on its upper end with recesses e
(Figures 4 and 6) through which the liquid can freely pass when the plug is
pressed down and can freely circulate around the latter to flow either in the
direction a', a (when the bottle is being filled) or in the direction a, a' (when the
vessel is being emptied).
Between the bottle F and the head A is placed a packing ring, which, when
compressed allows the clamp-shaped ring G, divided at g (Figure 3), to engage in
a groove in the head A and under the bottom edge of the shoulder of the
bottle-mouth a second ring G is then placed over the divided ring G (Figure 1).
By this arrangement a firm and tight connection of the closing-device with the
bottle or receptacle is effected without the application of screws.
The closing-device can, however, as shewn in Figure 2, be provided with a
socket-shaped extension a', in which the upper part of the bottle is placed and
cemented.
In order to fill the bottle or receptacle F or to empty the liquid from the bottle,
the knob C must be pressed down, whereby the rod or piston c will be caused to
force the plug B down from its seat, so that the liquid can enter the bottle in the
direction a a or can flow out from the vessel in the direction a a¹. Upon the
pressure on the knob C being relieved, the pressure of the gas will immediately
force the plug B upwards against its seat, whereby the further admission or
discharge of the liquid is prevented.
Our improved stoppering or closing-device can be very quickly mounted upon the
bottle or the receptacle and can as easily and quickly be removed, for the purpose of
cleaning the same or exchanging single parts thereof.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is :-
1. A stoppering or closing-device for aërated-water-bottles and similar receptacles,
consisting of a plug B movable in a hollow space in the head A between the
syphon-tube a and the discharge-tube a', the said plug being acted upon by the
pressure of gas inside the receptacle, thereby closing the discharge tube and being
further so arranged as to be removable from its seat by a depressing
contrivance C, c when the closing-device is to be opened, substantially as described
and shewn.
2. In a stoppering or closing-device for aërated-water-bottles and similar
receptacles such as is referred to in Claim 1, the elastic-packing tubes d, d
surrounding the bolt c in the upper part of the head A, substantially as, and for the
purposes, described.
3. In a device such as referred to in Claim 1, the socket E provided with recesses e
on its upper end, the said socket being arranged in the head A. and supporting the
syphon-tube a, substantially as described and shown.
4. In a device such as is referred to in Claim 1, a coupling-contrivance for
emnecting the closing-device with the receptacle, the said coupling-contrivance
consisting in the divided ring G and the ring G placed over the same, substantially
as described and shewn.
5. The improved means for stoppering or closing aërated-water-bottles and other

page_text: similar receptacles hereinbefore described and illustrated in the accompanying
drawing.
