Improvements in Stoppering Bottles for Containing Mineral Waters
or other Liquids Under Pressure.
I, CHARLES EDWARD BEAVIS, of Jacob Street, Bristol, Mineral Water
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 :-
My invention relates to a new and improved stopper for use in bottling mineral,
gaseous, , and other liquids, and has for its object to provide means whereby a screw-
stopper may be used with bottling machines and automatically sealed by a valve in
the stopper, without the delay and inconvenience caused by having to insert the
stopper after the bottle is filled.
My invention consists in making the screw stopper of the usual form and size,
but with a perforation from the top to the bottom, through which the liquid is
injected to the bottle by the machine, and fitted with a valve, self contained and
self supporting, that will effectively seal the stopper when the bottle is filled.
The nature and operation of this invention will be more fully described in
connection with the accompanying drawings, in which
Fig. 1 is a view of the stopper and valve ready for insertion in the bottle; Fig. 2
is a section of the same;
Fig. 3 is a plan view of the top of the stopper, and
Fig. represents the valve and spindle which is fitted in the perforation in the
stopper.
A is the top of an ordinary screw stopper, having a groove a cut round it to
receive a wire ring for attaching the stopper to the bottle; B is the ordinary
rubber washer to make the stopper air-tight, the screw part C fitting into the
bottle in the usual manner; a circular hole D is made, extending a suitable distance
through the stopper, and from this, the hole is continued with a smaller diameter E,
leaving a set off or seating d; connecting the upper and lower holes, two or more
chases or channels Fare formed to afford a free passage for the liquid and air.
A valve G on which a washer H is fitted, is attached to a spindle I, preferably
made triangular in shape, a collar or flange J being fastened to the top of the
spindle, which normally rests on the seating d and supports the spindle and valve.
The various parts being provided as described, the valve spindle 1 is inserted in
the perforation D, E, and the collar J put on to support it in the seating, and the
washer put on the valve, the stopper and valve will then be complete as shewn in
Fig. 1. ready for insertion in the bottle: one end of a piece of suitable wire may
be put round the groove a in the top of the stopper and fastened by twisting, and
the other end of the wire put around a similar groove or ring on the outside of the
bottle neck; or rings may be put in the groove of the stopper and round the neck
of the bottle, and connected together by a chain or other flexible material, this
forms a hinge or attachment to prevent the stopper being lost.
The stopper being inserted in the bottle, and the valve supported in the stopper
by the seating d, the bottle is ready for charging by the machine, the liquid is then
forced from the machine through the channels and perforation, and these at the
same time serve for the exhaustion of air from the bottle; when the bottle is
sufficiently full and the outside pressure removed, the compressed air in the bottle
will force the valve G and washer H against the lower part of the stopper, and
effectually seal it, the valve, washer, and collar occupying the positions shown by
dotted lines in Fig. 2; the spindle I is made triangular, so that it may be kept

page_text: steady against the perforated channel E, and yet allow as much space as possible
for the inlet of liquid and outlet of air.
The bottle is opened in the usual way, by simply unscrewing and taking out the
stopper, but if it be desired to liberate any superfluous gas before removing the
stopper, a finger can be placed on the collar J, which will be nearly level with
the top of the stopper, and by a slight pressure, the valve will be opened, and the
gas escape.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that I am
aware that stoppers have hitherto been made with perforations through them for
the purpose of filling and exhausting the air, to this I make no claim, but what I do
claim is :-
1. The construction of screw stoppers for bottling liquids under pressure, with
perforations through them of different diameters, thereby forming a seating to
support a valve for automatically sealing the stopper when the bottle is filled,
substantially as described.
2. In screw stoppers for bottling liquids under pressure, the insertion of a
valve as herein described, to be normally supported on au internal seating,
which automatically seals the stopper when the bottle is filled, substantially as
described.
3. With screw stoppers as described, the attachment of rings round the stopper
and neck of the bottle as herein set forth, and connecting them to each other by
wires, chains, or the like, substantially as described.
4. In the construction of screw stoppers, the combination of the several parts
herein described, whereby the bottles may be filled from a machine and sealed,
without the delay occasioned by having to insert the stoppers by additional or
secondary appliances; substantially as and for the purposes herein set forth and
described, and illustrated in the accompanying drawings.
