Improvements in or relating to Bottles or Vessels for Containing
Aerated Water, or otherwise liable to be subjected to Internal
Pressure.
I, THOMAS COPE, Junior, of The Old Mitre Inn, Essington, near Wolverhampton
in the County of Stafford, Engineer, do hereby declare the nature of this invention
to be as follows:-
Owing to the excessive pressure frequently existing within aerated water bottles
a considerable loss results in breakages, and moreover the ordinary pressure makes
it, as is well known, difficult to force in the stoppers when it is desired to open
the bottles.
Now, the object of this invention is to provide suitable means for allowing excess
of pressure beyond what is required in a bottle or vessel containing aerated water,
or in other bottle or vessel, to escape; and also to combine therewith means
whereby, in such cases as may be required, such for instance as in the case of an
aerated water bottle, the ordinary pressure may be relieved previously to opening
the bottle or vessel in the usual way, so that such opening may be effected with
greater facility than heretofore, and whereby such pressure may, if desired, be
reduced to that of the atmosphere, in which case the stopper (of an internally
stoppered bottle) will simply fall inwards.
According to this invention, a hole or holes is or are formed through the side of
the neck or other portion of the bottle or vessel and is or are covered by a rubber
or other elastic ring which is stretched around such neck or other portion, or by a
ring of metal, such as steel, having a pad or pads of rubber or other suitable
material which bears or bear around the hole or holes; and any excess of pressure
above that required within the bottle or vessel forces back the ring and allows of
the escape of sufficient gas to bring down the pressure to the desired point.
According to a convénient application of the invention, in the case more
especially of an aerated water bottle, a groove is formed around the neck of the
bottle, preferably by forming projections or collars therearound which leave the
groove between them and the hole or holes passes or pass from the interior of
the bottle out into the bottom of the groove. The groove is formed wider than tho
diameter of the hole or. holes, and the ring, which is of the same width as the
groove, is stretched into place therein. A notch is formed in one or each collar for
the whole depth thereof at the part which is adjacent to a hole, so as to allow ready
escape of the gas as it passes out under the ring; and, when it is desired to relieve
the pressure within the bottle previously to opening it in the usual way, a pointed
instrument, such as a skewer, may be pushed along the notch and under the ring so
as to raise it and allow of the escape of the gas. The whole of the pressure may
be allowed to escape in this manner, if desired, in which case the ordinary stopper
will fall down within the bottle, and the mouth of the bottle thus be left open.
The notch or notches may be of such width that the ring may be moved by the
finger to allow the escape of gas.
In
According to another application of the invention, a projection may be formed
on the bottom of the bottle, with a groove therearound for the reception of the ring,
and a passage be formed down from the interior of the bottle into such projection
with a hole or holes branching out therefrom into the bottom of the groove.
this case the wall of the bottle is carried down so as to form a ring or ledge_upon
which the bottle may stand, the projection being within the recess thus formed.
When a metal ring is employed, with a pad or pads for closing in a hole or holes,
the pressure may be readily relieved or released, when it is desired to open the

page_text: bottle, by simply inserting an instrument, or the finger, inside the ring and pulling
it slightly outwards to relieve or release the pressure upon the pad or one of
the pads.

COMPLETE SPECIFICATION.
Improvements in or relating to Bottles or Vessels for Containing
Aerated Water, or otherwise liable to be subjected to Internal
Pressure.
I, THOMAS COPE, Junior, The Old Mitre Inn Essington near Wolverhampton
Stafford Engineer, 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 :-
Owing to the excessive pressure frequently existing within aerated water bottles a
considerable loss results in breakage, and, moreover the ordinary pressure makes it,
as is well known difficult to force in the stoppers when it is desired to open the
bottle.
Now, the object of the invention is to provide suitable means for allowing
excess of pressure beyond what is required in a bottle or vessel containing aerated
water, or in other bottle or vessel, to escape and also to combine therewith means
whereby in such cases as may be required, such for instance as in the case of an
aerated water bottle the ordinary pressure may be relieved previously to
opening the bottle or vessel in the usual way, so that such opening may be
ellected with greater facility than heretofore, and whereby such pressure may if
desired be reduced to that of the atmosphere, in which case the stopper (of an
internally stoppered bottle) will simply fall inwards.
According to this invention, a hole or holes is or are formed through the side of
the neck, or other portion of the bottle or vessel, and is or are covered by a rubber
or other elastic ring which is stretched around, such neck or other portion, or by a
ring of metal such as steel having a pad or pads of rubber or other suitable
material which bears or bear around the hole or holes; and any excess of pressure
above that required within the bottle or vessel forces back the ring and allows of
the escape
of sufficient gas to bring down the pressure to the desired point.
According to a convenient application of the invention, in the case more
especially of an aerated water bottle a groove is formed around the neck of the
bottle preferably by forming projections or collars there around, which leave the
groove between them; and the hole or holes passes or pass from the interior of
the bottle out into the bottom of the groove. The groove is formed wider than
the diameter of the hole or holes, and the ring which is of the same width as the
groove, is stretched into place therein. A notch is formed in one or each collar for
the whole depth thereof at the part which is adjacent to a hole, so as to allow ready
escape of the gas as it passes out under the ring; and when it is desired to relieve
the pressure within the bottle previously to opening it in the usual way, a pointed
instrument, such as skewer may be pushed along the notch and under the ring so as
to raise it and allow of the escape of the gas. The whole of the pressure may be
allowed to escape in this manner if desired, in which case the ordinary stopper will
fall down within the bottle and the mouth of the bottle thus be left open. The
notch or notches may be of such width that the ring may be moved by the finger
to allow the escape of gas.
According to another application of the invention, a projection may be formed
on the bottom of the bottle with a groove there around for the reception of the
ring, and a passage be formed down from the interior of the bottle into such
projection with a hole or holes branching out therefrom into the bottom of the

page_text: groove. In this case the wall of the bottle is carried down so as to form a ring or
ledge upon which the bottle may stand, the projection being with the recess thus
formed.
When a metal ring is employed with a pad or pads for closing in a hole or holes,
the pressure may be readily relieved or released, when it is desired to open the
bottle by simply inserting an instrument, or the finger, inside the ring and pulling
it slightly outwards to release or relieve the pressure upon the pad, or one of the
pads.
In order that my invention may be fully understood I will now refer to the
annexed drawing in which
Fig. 1. shows in side elevation my invention adapted to a bottle.
Fig. 2. is a sectional elevation of same.
In Figure 1. a is the bottle which in this example is an aerated one such as a
soda water bottle. b is an indentation in which are formed the holes c which
communicates with the interior of the said bottle. The dotted lines represent the
flexible ring carrying the pad 9 (Figure 2). It will be seen that the pad g which
may be of any suitable material is secured to the flexible ring and by the
pressure exerted by the same is retained in the indentation & thus closes the
hole c.
The pressure exerted by the ring on the pad is so arranged as to allow
the gas in the bottle to escape, as soon as it has reached a preconcerted limit.
Having now particularly described and ascertained the nature of my said inven-
tion & in what manner the same is to be performed I declare that what I
claim is:
(1) In aerated water & other bottles for containing liquids under pressure, the
construction & arrangement of the bottle with or without the indentation >, with
holes c covered by a suitable ring & pad substantially as described & for the
purpose set forth.
