I, ALDERMAN HENRY COCHRANE, J.P. trading under the style and firm of
Cantrell and Cochrane, of. Dublin and Belfast, Ireland, Mineral Water Manu-
facturer, do hereby declare the nature of the said invention for "AN IMPROVED
METHOD FOR STOPPERING AND OPENING BOTTLES CONTAINING AERATED LIQUIDS
to be as follows :-
"
This Invention relates to bottles which are closed by a glass marble, disc, or
other stopper being pressed by the action of gas against a ring of india rubber or
other suitable material at the mouth of the bottle; and is especially designed to
permit such bottles being opened by releasing the gas thus obviating the necessity
of forcing the stoppers into the bottles, and reducing to a minimum the risk of
bottles bursting while being opened.
According to my said Invention, in the manufacture of the bottlo a screw thread
is formed on the outside of its nozzle or neck. Apart from the bottle is made a
cap, portion of the interior of which is threaded for the purpose of screwing down
upon the nozzle or neck of the bottle, and which when thus screwed down forms in
fact the mouth or lip of the bottle.
In the upper portion of the cap is a shoulder or projection against which rests a
collar or washer of india rubber or other suitable material for the purpose presently
described. The side of the cap is provided with a suitable aperture so that when
the cap is screwed down on the neck of the bottle the said aperture will be below
its rim.
The action of my said Invention may be briefly described thus:-When the
bottle is being filled the cap is screwed into position, the glass ball or stopper
having been first introduced into the bottle. Upon the bottle being fully charged
with aërated liquid the ball is caused.to press against the collar of india-rubber or
other material arranged in the cap, thus effectually closing the bottle.

page_text: In order to open the bottle the cap is screwed round until the aperture in ita
side comes above the rim of the bottle, when the gas will escape and the glass ball
fall away from the rubber collar thereby enabling the contents to be poured out
with ease.
For the purpose of preventing the glass ball from running into the mouth of the 5
bottle while the contents are being poured out, an internal shoulder or flange or a
series of longitudinal or transverse grooves may be formed in the interior of the
bottle.

page_text: I, ALDERMAN HENRY COCHRANE, J.P., trading as Cantrell and Cochrane, Dublin
and Belfast, Mineral Water Manufacturer, do hereby declare the nature of my
invention for AN IMPROVED METHOD FOR STOPPERING AND OPENING BOTTLES
CONTAINING AËRATED LIQUIDS 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 bottles which are closed by a glass marble, disc, or
other stopper being pressed by the action of the gas contained within the bottle
against a ring of india rubber or other suitable material at the mouth of the bottle;
and is especially designed to permit such bottles being opened by releasing the gas,
thus obviating the necessity of forcing the stoppers into the bottles, and reducing
to a minimum the risk of bottles bursting while being opened,
According to my said Invention in the manufacture of the bottle a screw-thread
is formed on the outside, or insido, of its nozzle or neck. I construct a cap of glass,
metal, or other suitablo material, on the interior, or exterior, of which (according as
the screw-thread has been formed on the outside or inside of the neck of the bottle)
a corresponding screw-thread is formed for the purpose of screwing on the cap,
which, when screwed down, forms the mouth or lip of the bottle In the upper
portion of the cap is a shoulder or projection against which a rests a collar or
washer of indiarubber or other suitable material, for the purpose presently
described. The side of the cap is provided with a suitable aperture, so placed
that when the cap is screwed on, the gas cannot escape; or instead of such aperture
a groove or channel may be formed across the threads of the screw; or the cap
may be made to fit loosely; so that in each case, when the cap is partially
unscrewed, from its seat, the gas can escape.
The action of my said Invention may be briefly described thus:-Before the
bottle is filled, the glass ball or stopper is inserted, the cap is screwed into position,
the shoulder or projection being pressed tightly on the washer of indiarubber. The
bottle is then charged with aërated liquid, whereby the ball or stopper is caused to
press against the collar or washer arranged in the cap, thus effectually closing the
bottle. In order to open the bottle, the cap is screwed round until the gas escapes,
so that the pressure is removed from the underside of the glass ball or stopper,
which falls from its seat; thereby enabling the contents to be poured out
with ease.
In order that my said Invention may be more readily understood, and carried
into practice, I will describe the accompanying drawings:-Fig. 1 is an elevation
and fig. 2, a section shewing the application of an external cap, made according to
my Invention, to a bottle, in the manner described; fig. 3 is an elevation and fig 4
section illustrating the application of an internal cap, made according to my
Invention. In figs. 1 and 2 a a represents the cap screwed on to the neck of the
bottle; The shoulder or projection is indicated at b, in which rests the washer or
Collar c. Against this collar or washer impinges the ball or stopper as shown, dis

before described; or a channel may be cut across the screw-thread as shown in
dotted lines, fig 2. In the internal cap arrangement, illustrated in figs 3 and 4, a
shoulder or projection similar to that described at b, fig. 2, may be used, or an
annular groove similar to that shewn at e, fig 4, in which the indiarubber washor
lies. The top of this cap may be formed with a flange having a milled edge to
facilitate screwing and unscrewing, and underneath this flange is arranged the
outer washer of india rubber f, so that when the cap is screwed into the neck of
the bottle the said collar or washer f will be pressed against the rim or edge of the
bottle, and thus form an airtight joint. In all cases when the cap is tightly
screwed down, the shoulder or projection of the cap is made to press upon or against
a washer or washers of indiarubber, so as to make an air-tight or gas-tight joint or
joints. The channel across the screw threads is.shewn in dotted lines on fig 3, or
an aperture g, fig. 4, may be used.
It is obvious that according to my Invention it is not necessary to remove tho
cap in any case from the bottle, seeing that the bottle can be charged, opened, and
emptied of its contents in the manner hereinbefore described.
Having now particularly described and ascertained the nature of my said
Invention, and in what manner the same is to be performed, I desire to say that
I am aware that screw threads have been used in order to secure indiarubber and
other washers; but what I believe to be novel and original, and therefore claim is
The arrangement substantially as hereinbefore described of a screw-cap in
combination with the ball or Stopper and washer or washers, whereby the partial
unscrewing of the Cap enables the contents of the bottle to be poured out.
