page_text: I, ARTHUR READ POLLARD, of 18, Warwick Place, Worthing, in the County of
Sussex, Master Sign Writer, do hereby declare the nature of this invention to be as
follows:-
This invention relates to stoppers for bottles and the like, and consists of an
improved stopper and bottle neck adapted to the same as well as a device for use in
filling the bottles or other liquid receptacles in which these stoppers are used.
Bottles stoppered according to this invention can be produced at a low first cost,
and are much more easily opened than in any other method in use at the present.
The neck of the bottle is contracted close to the mouth forming an internal
shoulder and channel, in which an annular ring of rubber or other substance is
inserted in such manner that when the stopper is pressed by the pressure in the
bottle against the shoulder, an air-tight joint is formed.
The stopper is of a globular shape or approximating thereto and preferably formed
of glass, it is of less diameter than the neck of the bottle so that an annular space is
left round it through which the liquid contents can pass. But the stopper is of
greater diameter than the contracted part of the neck of the bottle near its mouth;
consequently the stopper has to be inserted in the neck while the bottle is being
manufactured. The stopper has a small ear or projection formed integrally with it,.
which, when the bottle is full projects so as to be almost flush with the mouth of the
bottle, and stands normally in its centre. A number of grooves or depressions are formed
in the stopper in such a position that when the stopperis in the position above described,
none of them are open to the atmosphere. But when by a slight pressure on the
ear or projection the stopper is rocked on its rubber seat so that the ear touches one
side of the hottle mouth, one or more of the grooves or depressions opens to the
atmosphere and, it being open to the interior of the bottle also, the gas rushes
out, the pressure is reduced and the stopper falls into such a position in the neck of
the bottle that the liquid can be poured out.
The stopper is prevented from falling into the mouth of the bottle by the neck of the
latter being contracted with one or more radiating internal grooves, which allows
the liquid to pass the stopper.
When filling bottles stoppered in this manner I use a guide which ensures the ear
or projections being in the centre of the mouth.

page_text: I, ARTHUR READ POLLARD, of 18, Warwick Place, Worthing, in the County of
Sussex, Master Sign Writer, 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 relates to stoppers for bottles and the like, and consists of an
improved stopper, and bottle neck adapted to the same, as well as a device for use
in filling the bottles or other liquid receptacles in which these stoppers are used.
Bottles stoppered according to this invention can be produced at a low first cost, and
are much more easily opened than in any other method in use at the present.
The neck of the bottle is contracted close to the mouth forming an internal
shoulder and channel, in which an annular ring of rubber or other substance is
inserted in such inanner that when the stopper is pressed by the pressure in the
bottle against the shoulder an airtight joint is formed.
The stopper is of a globular shape, or approximating thereto, and preferably formed
of glass, it is of less diameter than the neck of the bottle so that an annular space
is left round it through which the liquid contents can pass. But the stopper is of
greater diameter than the contracted part of the neck of the bottle near its mouth;
consequently the stopper has to be inserted in the neck while the bottle is being
manufactured. The stopper has a small ear or projection formed integrally with it
which when the bottle is full projects so as to be almost flush with the mouth of the
bottle, and stands normally in its centre. A number of grooves or depressions are
formed in the stopper in such a position that when the stopper is in the position
above described none of them are open to the atmosphere. But when by a slight
pressure of the finger on the ear or projection the stopper is rocked on its rubber
seat so that the ear touches one side of the bottle mouth, one or more of the grooves
or depressions opens to the atmosphere, and it being open to the interior of the
bottle also, the gas rushes out, the pressure is reduced, and the stopper falls into
such a position in the neck of the bottle that the liquid can be poured out.
The stopper is prevented from falling into the bottle by the neck of the latter
being contracted with one or more radiating internal grooves which allows the
liquid to pass the stopper.
When filling bottles stoppered in this manner I use a guide which ensures the
ear or projection being in the centre of the mouth.
In order that my invention may be more fully understood and ascertained I
append drawings, in which.
Fig. 1 is a section of the upper half of a bottle shewing my improved stopper
applied thereto.
Fig. 2 is a section through line x-x of Fig. 1.
Fig. 3 shews my improved stopper (shewn in a slanting position in dotted lines).
Fig. 4 is a sectional elevation of my improved guide for use in filling the
bottle, and
Fig. 4 is a plan of same.
Referring to Fig. 1 A indicates the upper part of the body of the bottle and B
the neck which is of the form shewn. Just inside the neck of the bottle, which is
suitably contracted an annular groove or depression is formed, in which is inserted
an india rubber or other ring a in such manner as to form an airtight joint when
the stopper is forced up against it by the inside pressure.
The stopper bis of globular form, or approximating thereto, and preferably made
of glass. It is of smaller dimensions than the neck, but larger than the mouth of

page_text: the bottle, and is formed with a projection or ear c which when the bottle is filled
projects upwards so as to be almost flush with the mouth of the bottle. The stopper
has preferably a second projection or ear c', of spherical, or any other suitable
form, situate opposite the projection c to balance the stopper and ensure that the
ear or projection c shall be kept in an upright position, and also to prevent the
stopper turning the wrong way.
At C the neck is contracted with one or more radiating internal grooves as shewn
in Fig. 2 to prevent the stopper from falling into the body of the bottle, while at the
same time allowing the liquid to pass around the stopper into the body of the bottle.
62 represents the stopper in its normal position or when the bottle is empty, and 63
shews same in position when the bottle is being emptied of its contents.
The neck of the bottle has an indentation formed on one side which acts as an
internal ledge or projection E on which the stopper rests when the bottle is being
emptied, thereby preventing it from choking the mouth of the bottle by the force of
the liquid behind it.
The body of the stopper is formed with a number of grooves or depressions e in
such manner as to allow the gas to escape from the inside of bottle when the stopper
is turned on one side as in b₁.
In filling bottles of this description I use a guide shewn in Figs. 4 and 4 to ensure
that the projection c shall be in an upright position by being held in the centre
thereof.
My improved guide is formed with a central aperture & in which fits the ear or
projection c of the stopper, and also with a circular flange d², and a flange d³,
preferably of rubber, which rests upon the top of the bottle. It is formed of any
suitable material, and has a number of slits or grooves radiating from the centre,
so as to allow the liquid to pass down round the ear or projection c of the stopper b.
The action of my improved bottle stopper is as follows.
The stopper being inserted in the neck of the bottle while it is being manufactured,
would assume the position 62 shewn in dotted lines, but when the bottle is being filled
it falls to the position of 6 being held in an upright position by the guide. When in
this position the gas inside forces it against the rubber or other ring and forms an
airtight joint, as the grooves e in the stopper are not open to the atmosphere; but on
turning or rocking the stopper by means of the ear or projection c to one side of the
mouth of the bottle, as shewn in dotted lines by b¹, one or more of the grooves e
immediately opens the interior of the bottle to the atmosphere. This allows the gas
to escape, and the stopper then falls to the position b². On the bottle being turned
on the side of the indentation the stopper rests against the ledge or projection E and
allows the liquid to flow out.
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. A stopper for bottles and like articles, consisting essentially of a ball of globular
or similar form, and preferably made of glass, having grooves or depressions formed
in it in such manner that when the bottle is filled and the stopper is in its normal
closed position these grooves shall not be in communication with the atmosphere,
but on the stopper being turned to one side, by means of an ear or projection formed
integral therewith, one or more grooves will simultaneously be opened to the
atmosphere and to the interior of the bottle, thus allowing the gas inside the bottle
to escape, substantially as shewn and described.
2. In stoppers for bottles and like articles, forming the stopper with grooves, and
with one or more ears or projections, substantially as, and for the purpose, hereinbefore
described and shewn.
3. In combination with bottle stoppers as herein described, a neck formed with an
indentation to constitute an internal ledge against which the stopper rests when the
bottle is being emptied, said neck being also contracted with one or more radiating

page_text: internal grooves to prevent stopper from falling into the body of the bottle, while at
the same time allowing the liquid to flow round the stopper into the body of the
bottle, substantially as described and shewn.
4. For use in filling bottles constructed according to my invention, a guide substan-
tially as shewn and described with reference to Figs. 4 and 4*, of the accompanying
drawings.
Dated this 8th day of November 1897.
