We, HENRY BARRETT, Stopper Manufacturer, and JOHN JAMES VARLEY, Engineer,
both of No. 268, South Lambeth Road, in the County of Surrey, do hereby declare
the nature of this invention to be as follows:-
Our invention relates to bottles having internal stoppers which are held to elastic
seats fitted in the necks of the bottles by the pressure of gas contained in the
bottles.
Our said invention has for object to provide a ready, easy, and safe means of
opening such bottles without the necessity of forcing the stopper inwards against the
pressure contained in the bottle, which operation is frequently attended with danger
and to this end our invention comprises the improvements hereinafter described.
We form a loop of wire or metal or other suitable material having the ends turned
outwards and flattened, and so shaped that they may be placed between the top side of
the elastic ring or seating and the under side of the upper shoulder of the groove in
the bottle neck into which the ring or seating is placed. The loop which normally
lies at or near one side of the mouth of the bottle extends to or just above, the top of
the mouth and forms what may be termed a lever.
When it is desired to open a bottle which contains aërated or other liquids under
pressure the top of the loop or lever is moved from the one side of the mouth towards
the other side, whereby the ring or seating will be compressed so that the gas can
escape. At the same time the stopper will be forced slightly downwards so that when
the gas shall have escaped the stopper will drop to a lower position in the bottle. The
loop or lever may he pressed downwards to produce the same result.
One important feature of our invention is that it can be applied to bottles which are
already in use at a very small cost, rendering such bottles safe in the hands of the
public; and another advantage is that it provides against the loss of rings.

page_text: We are aware of inventions for the above. described objects but in all such
inventions the bottles, of necessity, have to be specially constructed thus preventing
their application to the vast number of bottles now in use.

Improvements relating to Means for Facilitating the Opening of
Internally Stoppered Bottles for Aërated and other Liquids.
We, HENRY BARRETT, Stopper Manufacturer, and JOHN JAMES VARLEY, Engineer,
both of No. 268, South Lambeth Road, in the county of Surrey, 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 the opening of bottles having internal stoppers which are
held close to clastic seats or rings fitted in the necks of the bottles by the pressure of
gas contained in the said bottles, and has for its chief object to provide ready, easy,
and safe means for effecting the opening and escape of the confined gas, which means
are applicable as well to bottles already in use as to similar bottles when new inasmuch
as our improved device may be applied without altering the surfaces of the bottles
either by removing or perforating any part of the same.
To this end we employ a
bow or loop or lever of novel application and construction by means of which the
elastic seating and the stopper may be displaced so as to allow of the gradual escape
of the gas.
In the accompanying drawing
Figure 1 is a front elevation of the upper portion of a bottle of ordinary construction
having our improvements applied thereto.
Figure 2 is a vertical section of the bottle neck with the stopper and opening device
drawn to an enlarged scale.
Figure 3 is a similar section at right angles to that shown in figure 2.
Figure 4 is a sectional view illustrating the operation of the opening device.
a is the bottle neck, is the elastic seating located in a suitable recess below the
flange or shoulder c, and d is a stopper, all of these parts being of ordinary
construction.

e is a loop of wire or other suitable material having the ends f, turned outwards
and flattened or cam-shaped, as shown in figure 3, so that they may be placed between
the top side of the clastic ring or seating b and the under side of the shoulder c of the
groove in the bottle neck into which the ring or seating is placed. The loop which
normally lies at one side of the mouth of the bottle, as shown in figures 1 and 2,
extends to or just above the top of the mouth, also as shown in figure 2 and forms
what may be termed a lever.
When it is desired to open a bottle which contains aërated or other liquids under
pressure the top of the loop or lever is moved from the one side of the mouth towards
the other side, that is to say, from the position shown in figure 2 to that shown in
figure 4, whereby the ring or seating will be compressed or displaced by the ends f, f
of the loop so that the stopper will not bear evenly thereon, thus allowing the gas to
escape. At the same time the stopper will be forced slightly downwards so that,
when the gas shall have escaped, the stopper will drop to a lower position in the bottle,
for instance, onto the support g, figure 1. The loop or lover may be arranged so as to
be pressod downwards to produce the same result.
As hereinbefore stated a very important feature of our invention is that it can be
applied to bottles which are already in uso at a very small cost without altering their
shape or cutting away part of the material of the bottle or adding to it means for
holding or working the loop or lover opener.
We are thereby enabled to make old bottles more efficient inasmuch as they can bo
more readily and safely opened than when round stoppers or balls are used according
to the old plan; and another advantage is that it provides against the loss of rings,
which often occurs with bottles in ordinary use.
We wish it understood that we do not limit ourselves to the form of lever or loop
hereinbefore described, but it should be noted that it is advisable that it should have
one or both ends flattened or cam-shaped so as to slightly displace the seating or ring
when it is moved on one side so as to bring the lever into play.
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. The combination with a bottle which is adapted to be closed by means of a
stopper held against an elastic seating in the neck by the pressure of gas contained in
the bottle, of a loop or lever having one or both of its ends adapted to be inserted
between the upper shoulder of the recess in which the said seating is located and the
seating itself, one or both ends of the said loop being flattened or shaped, substantially
as, and for the purpose setforth.
2. The combination with a bottle having an elastic seating located in the neck
thereof, of a loop or lever such as e having its end or ends adapted to displace the said
ring when it is moved, substantially as, and for the purpose, described.
3. The manufacture of levers or loops such as e having the end or ends thereof so
shaped as to be suitable for the purposes above mentioned substantially as described.
