LAUCHLAN ROSE, of 11, Curtain Road, Finsbury, in the County of Middlesex,
Lime Juice Merchant. "AN IMPROVED OPENER FOR BOTTLES CONTAINING AËRATED
OR GASEOUS LIQUIDS CLOSED BY INTERNAL STOPPERS."
The usual mode hitherto adopted for opening aërated water bottles closed
by means of internal stoppers has been by means of a cup shaped plunger
known in the trade as "button openers," the cup or button being provided
with a short stem or spindle, which is pressed down upon the stopper, thus
displacing it from its position in the neck, enabling the bottle to be decanted.
The great objection to the use of such and similar openers is that no provision
is made for relieving the gas or air pressure in the bottle, and consequently
upon this displacement of the stopper the contents of highly charged bottles,
such as those containing soda water, potass water, or seltzer water, are forced
up by the gas pressure, generally splashing the person opening the bottle before
he or she can decant the contents into the glass.
Now the object of my Invention is to provide an opener which shall obviate
these objections, and my improvements consist in providing a short tube of such a
diameter as to allow its entrance into the mouth of the bottle to be opened and
provided with an outside flange or rim at or near its centre, on one side of which
I attach or fix a tube of rubber, cork, or other suitable material of sufficient
diameter to tightly close the mouth of a bottle or other hollow receptacle when
forced or pressed into it, without closing the herein before described tube; and on
the other side of the flange I place a washer of rubber, leather, or other suitable
material, so that upon the tube being pressed down upon the stopper of the bottle re-
quiring to be opened, such washer will at once rest upon the lip of the bottle, making
an air tight connection with the other bottle or hollow receptacle by means of the
tube opener, and by these means the gas or air pressure in the bottle requiring to
be opened is at once relieved by the escape of the gas or air into the receptacle, and
the bottle may be decanted without that spilling of the contents, which generally
accompanies the present mode of opening as hitherto adopted. It will be seen that
this tube opener may be adapted to any size of bottle mouth by having the tube
covering of rubber or cork, or other suitable material, of a cone form, which will
adapt itself to the opening of the neck or mouth of the bottle or other hollow
receptacle to be used in connection with it.

page_text: Another form of my improved opener and the one preferred by me is in the form
of a small bottle or other hollow receptacle with an elongated neck of such a
diameter as to allow of its insertion into the mouth of the bottle which it is
required to open, provided with a ring or flange outside at a short distance from
the lip of such bottle or receptacle, and on which ring or flange on the side
nearest the lip I place a washer of rubber or other suitable material, so that upon
the insertion of the opener and the pressing down of the stopper, the washer will
at once rest upon the lip of the bottle requiring to be opened, thus forming an air-
tight connection with the receptacle of the opener, and thus relieving the gas or
air pressure by allowing the air or gas to pass into the receptacle, by which means
the bottle may be decanted without the loss or spilling of its contents.
