Improvements in or Applicable to Bottles and Stoppers for Aërated
or Gaseous Liquids,
I JOHN JAMES VARLEY, of No. 268 South Lambeth Road, in the county of Surrey,
Manufacturer, do hereby declare the nature of this invention to be as follows:-
This invention has for object to provide improved means for discharging a portion
of the gas contained in bottles containing acrated or gaseous liquids and closed with
internal stoppers thereby allowing of the bottles being opened with ease, facility and
safety.
For this purpose in the case for example of a bottle closed by means of an internal
stopper such as a ball which is forced by the internal pressure against an elastic ring
or seating fitted in a groove in the neck of the bottle I provide a pusher which works
in a hole passing from the outside of the bottle neck into the groove in which the said
elastic seating is placed so that by pressing the said pusher inwards the portion of the
outer circumference of the elastic seating against which the pusher acts will be slightly
moved or compressed inwards and thereby open a passage for the escape of the gas
within the bottle after which the stopper will drop from its seating or can be easily
removed therefrom. The stem of the pusher is in some cases channelled or formed
hollow to facilitate the escape of the gas and can be provided with any suitabbe
packing.
In some cases the end of the pusher is bent and passes through the seating which
arrangement prevents the seating from being entirely forced out of its groove.
Instead of providing for the escape of the gas by means of a pusher acting on the
elastic seating I sometimes perforate the elastic seating itself or channel the outer
circumference thereof so that a comparatively slight pressure on the stopper will allow
the gas to escape through the said perforations or channels. Or in place of perforating
the seating as above named the stopper itself may be perforated.

Improvements in or Applicable to Bottles and Stoppers for Aërated
or Gaseous Liquids.
I, JOHN JAMES VARLEY, of No. 268, South Lambeth Road, in the county of
Surrey, Manufacturer, 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
This invention has for object to provide improved means for discharging a portion
of the gas contained in bottles containing aërated or gaseous liquids and closed with
internal stoppers thereby allowing of the bottles being opened with ease, facility, and
safety.
For this purpose in the case for example of a bottle closed by means of an internal
stopper such as a ball which is forced by the internal pressure against an elastic ring
or seating fitted in a groove in the neck of the bottle, I provide a pusher which works
in a hole passing from the outside of the bottle neck into the groove in which the said
elastic seating is placed so that by pressing the said pusher inwards the portion of the
outer circumference of the elastic seating against which the pusher acts will be
slightly moved or compressed inwards and thereby open a passage for the escape of
the gas within the bottle after which the stopper will drop from its seating or can be
easily removed therefrom.
In the accompanying drawing figures 1 to 8 illustrate sections of the necks of
bottles provided with a pusher as above named; a, is the bottle neck; b, the usual
rubber ring therein, and c, the internal ball stopper; d, represents my pusher which
consists of a stem which slides in a hole in the side of the neck of the bottle, the inner
end being enlarged so as to prevent it being withdrawn from the bottle-the outer end
of the pusher having a knob or button e.
In figure the inner end of the pusher bears against the periphery of the rubber
ring; in figure 2 it bears against the periphery and the upper surface of the ring; in
figure 3 against the periphery and the upper and under surfaces and in figure 4 against
the periphery and the under surface. Figure 5 shews the inner end of the pusher
embedded in the rubber ring and being attached thereto will prevent the ring from
becoming detached from the bottle.
The stem of the pusher is in some cases channelled as in figure 7 or formed hollow
as in figure 6 to facilitate the escape of the gas and can be provided with any suitable
packing and in these figures the end of the pusher is bent and passes through the
seating which arrangement also prevents the seating from being entirely forced out of
its groove, and the pusher being channelled as shewn in figure 7 or formed hollow or
tubular as shewn in figure 6, the gas from the bottle can escape freely when the ring
is pressed by its pusher.
In figure 8 the bottle is formed with a projecting ring f, on the outside of the neck
*for the purpose of strengthening the neck at this part and to give a longer and better

page_text: guide to the stem of the pusher. In this figure the stem of the pusher works through
a packing ring 9, (or a stuffing box) in the groove of the neck of the bottle, the object
of this arrangement is to prevent a portion of the liquid passing out of the bottle with
the gas and thus prevent the fingers from getting wet; or a recess may be formed at
the back of the groove at that part at which the pusher works in the hole; the pusher
is in every case either enlarged at the end inside the bottle or otherwise formed so that
it cannot be removed from its place and in order to allow for this, the hole passing
from the groove to the outside of the bottle may be enlarged or countersunk on the
inside so as to allow room for any enlargement at the end of the pusher or for an india
rubber washer.
Instead of providing for the escape of the gas by means of a pusher acting on the
elastic seating I sometimes perforate the elastic seating itself as shewn at h, h,
figures 9 and 10, or channel the outer circumference thercof as at i, i, figures 11
and 12, so that a comparatively slight pressure on the stopper will allow the gas to
escape through the said perforations or channels.
Or in place of perforating the seating as above named the stopper itself may be
perforated as represented at figures 13, 14, 15 and 1.6.
Figure 13 shews the neck of a bottle with a stopper constructed with a hole k,
passing from near the seat or under side of the ring to the outside of the bottle so that
on pushing the stopper slightly on one side the gas in the bottle will have a free
passage out of the bottle. Figures 14, 15, and 16 also shew stoppers having holes or
passages which when the stopper is held against the seating by the pressure within
the bottle will be closed but a slight pressure on one side of the stopper will open the
passage so that the gas will escape from the bottle.
Having now particularly described and ascertained the nature of my said invention
and in what manner the same is to be performed I declare that what I claim is :-
1. Providing bottles for containing aërated liquids and closed with internal stoppers
bearing against elastic seatings in the necks of the bottles, with a pusher working in a
hole passing horizontally from the outside of the bottle neck to the groove in which
the said elastic scating is placed for the purpose and in the manner substantially as
herein before described and illustrated in figures 1 to 8 of the accompanying
drawing.
2. Perforating or channelling the elastic seatings of bottles containing aërated
liquids and closed by internal stoppers substantially as and for the purpose herein-
before described and illustrated in figures 9 and 10 and 11 and 12 respectively of the
accompanying drawing.
3. Perforating internal stoppers for bottles having elastic seatings in the necks
thereof substantially as and for the purpose herein-before described and illustrated in
figures 13 to 16 of the accompanying drawing.
