PROVISIONAL SPECIFICATION.
Improvements in or relating to Stoppers or Corks for Bottles
and the like.
HENRY WILLIAM BARTON, Esq., 48, Stratford Road, Plaistow, E., Oil, Colour,
and General Store Manager, do hereby declare the nature of this invention to
be as follows:-
This invention consists of improvements in or relating to stoppers or corks
for bottles and the like, the object being to provide a simple and effective means
for closing a bottle when required, or opening it, of a material of sufficient
cheapness when required to enable it to be discarded after use.
For the purpose of illustration I will describe how I carry out my invention.
The stopper is formed of any suitable material such for instance as that having
a flexible nature when required and is so shaped as to engage upon and close
the neck of the bottle through the medium when desired of a ring or shoulder
upon which the stoppering portion bears. This stoppering portion has the re-
quired curvature and upon its upper surface carries projections or shoulders
having inclined surfaces adapted to engage upon corresponding projections or
shoulders having inclined surfaces upon the neck of the bottle. The stopper
is cut and recessed to enable it to pass these projections or shoulders so as to
allow the inclined surface upon the stopper to come into contact therewith being
so arranged that upon rotating the stopper, the inclined surface will cause the
stoppering surface to bear upon and close the bottle. A suitable thumb piece
or projection is provided for enabling the stopper to be operated when required.
The stoppers may be made of material which might be employed in more than
one bottle, but by the construction of my stopper, might be made of material
sufficiently cheap to warrant its being discarded after the contents of the bottle
had been consumed.

I, HENRY WILLIAM BARTON, 48, Stratford Road, Plaistow, E., Oil, Colour, and
General Store Manager, do hereby declare the nature of this invention and in

page_text: what manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement:-
-
This invention consists of improvements in or relating to stoppers or corks
for bottles and the like, the object being to provide a simple and effective means
for closing a bottle when required or opening it, which may be formed of a
material of sufficient cheapness when required to enable it to be discarded after
use.
For the purposes of illustration, I will describe the way in which I carry out
my invention. The stopper is formed of any suitable material such for instance
as that having a flexible nature when required and is so shaped as to engage
upon and close the neck of the bottle through the medium when desired of a
ring or shoulder upon which the stoppering portion bears. This stoppering
portion has the required curvatures and upon its upper surface carries projec-
tions or shoulders having inclined surfaces adapted to engage upon corresponding
projections or shoulders having inclined surfaces upon the neck of the bottle.
The stopper is cut and recessed to enable it to pass these projections or shoulders
so as to allow the inclined surface upon the stopper to come into contact there-
with being so arranged that upon rotating the stopper, the inclined surface will
cause the stoppering surface to bear upon and close the bottle. A suitable
thumb piece or projection is provided for enabling the stopper to be operated
when required. The stoppers might be made of material which might. be em-
ployed in more than one bottle, but by the construction of my stopper might
be made of material sufficiently cheap to warrant its being discarded after the
contents of the bottle had been consumed.
For purposes of illustration, I will now refer to the annexed drawings in
which I have shewn one form of my stopper applied to a bottle.
Figure 1, is a sectional side elevation.
Figure 2, side view of stopper.
Figure 3, plan view of stopper.
a is the bottle neck which is provided with shoulders b and c and the seating d.
The stopper e is formed of material of sufficient cheapness to enable it to be
discarded if required. This stopper is provided with the seating fand has the
shoulders or inclined surfaces g thereon, being recessed at h to enable the stopper
to be inserted in the neck of the bottle a and pass the projections & thereon:
By rotating the stopper in the required direction, the inclined surfaces g will
come into contact with the projections & c in the neck of the bottle and so
cause the seating surface fto bear upon the seating formed in the neck of
the bottle. Of course it would readily suggest itself that the stopper may be
so arranged as to allow of a certain amount of independent movement between
the seating surface and the locking part of the stopper. is the thumb piece
or projection for enabling the stopper to be operated when required. As is
well known, there are various substances which might be utilised for the manu-
facture of my stopper, and it adapts itself to being moulded or formed by com-
pression of various ingredients, some of which are of such a price as to warrant
the discarding of the stopper after use.
Having now particularly described and ascertained the nature of my said in-
vention, and in what manner the same is to be performed, I declare that what
I claim is:-
1. The new or improved stopper for bottles, substantially as described and
illustrated herein and for the purpose set forth.
2. In stoppers for bottles of the class herein described, a stopper formed of
suitable material and so shaped as to have a stoppering surface which is brought
into operation through the medium of inclined shoulders or plates upon said
stopper, thus engaging upon corresponding projections or surfaces formed in
the neck of the bottle, a thumb piece for the purpose of securing the stopper

page_text: in position or removing same, recesses in said stopper for the purpose of pass-
ing the securing shoulders or projections upon the neck of the bottle, substan-
tially as described and illustrated herein and for the purpose set forth.
