page_text: I, SEPTIMUS ALEXANDER PARKES, of Holbrook, Park Road, Surbiton, Surrey,
Gentleman, do hereby declare the nature of this invention to be as follows:--
This invention relates to improvements in screw stoppers and has for its object
to provide simple and efficient means whereby the bottle or jar may be rendered
airtight and also present to the contents of the bottle a stopper formed of non-
corrodible material.
In carrying out my invention I provide the neck of the bottle or jar with a
screw thread over which screws a cap preferably of metal. Inside this cap I
provide a disc preferably of non-corrodible material such as glass, earthenware,
porcelain or the like, which fits loosely in the metal cap but is prevented from
dropping out by a series of projections formed round the inside of the cap after
the disc is in position or by any other suitable means. This disc completely
covers the mouth of the bottle and a band or ring of rubber or other resilient
material is placed either on the-neck of the bottle or on the stopper thereby closing
the bottle on screwing the cap up tight and presenting a non-corrosive surface
to the contents of the bottle.
The rubber ring may be placed in a groove formed in the upper edge of the neck
and the disc may be formed with a ring near its periphery which passes over the
rubber band and presses it out thereby sealing the jar.
This ring may be bevelled outwards and the edge of the neck correspondingly
bevelled and provided with a groove to contain the ring.
Several other methods may be adopted to form the joint thus a projecting piece
may be formed on the dise and provided with a groove on the edge into which the
rubber ring is placed, and the mouth of the bottle bevelled outwards so that the
ring bears against this, or, a channel may be formed on the cap or upper edge of
the neck and the band or ring placed therein and the bottle or disc provided with
a projecting ring which presses against the rubber band on screwing the cap tight.
These channels and projecting rings may be bevelled or sloped outwards or
inwards if found desirable.
Thus there is no metal or other corrosive material in connection with the con-
tents of the bottle and so it is especially applicable to bottles containing pickles
and the like.

page_text: I, SEPTIMUS ALEXANDER PARKES, of Holbrook, Park Road, Surbiton, Surrey,
Gentleman, 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 improvements in screw stoppers and has for its object
to provide simple and effective means whereby the bottle may be rendered air
tight and also present to the contents of the bottle a stopper formed of non-
corrodible material.
In carrying out my invention I provide the neck of the bottle with a screw
thread over which screws a cap preferably of metal. Inside this cap I provide a
disc preferably of non corrodible material, such as glass, earthenware, porcelain
or the like, which fits loosely in the metal cap but is prevented from dropping out
by a series of projections formed round the inside of the cap after the disc is in
position or by any other suitable means. This disc completely covers the mouth
of the bottle and a band or ring of rubber or other resilient material is placed
either on the neck of the bottle or on the stopper thereby closing the bottle on
screwing the cap up tight and presenting a non-corrosive surface to the contents
of the bottle.
The rubber ring may be placed in a groove formed in the upper edge of the
neck and the disc may be formed with a ring near its pèriphery which passes over
the rubber band and presses it out thereby sealing the jar.
This ring may be bevelled outwards and the edge of the neck correspondingly
bevelled and provided with a groove to contain the ring.
Several other methods may be adopted to form the joint. Thus a projecting
piece may be formed on the disc, and provided with a groove on the edge into
which the rubber ring is placed, and the mouth of the bottle bevelled outwards
so that the ring bears against this, or a channel may be formed in the cap or
upper edge of the neck, and the band or ring placed therein and the bottle or disc
provided with a projecting ring which presses against the rubber band on screwing
the cap tight. These channels and projecting rings may be bevelled or sloped
outwards or inwards if found desirable.
Thus there is no metal or other corrosive material in connection with the con-
tents of the bottle and so it is especially applicable to bottles containing pickles
and the like.
In order that the invention may be more clearly understood, reference is had to
the accompanying sheet or drawings, in which Fig. 1 is a section of the head of
a bottle provided with my improved stopper, and Figs. 2 to 9 are similar views of
slightly modified forms.
As shown in Fig. 1 the top of the bottle A is formed with the screw threaded
part a and the stepped portion a. On top of this bottle the cap B is screwed, and
within the cap the disc C is placed of glass, earthenware or other incorrodible
material. This disc is provided with the flange c which projects over the stepped
or rebated portion of the bottle. The outer edge of the top of the bottle is formed
with the small groove a within which the rubber ring D is placed. On screwing
the cap down firmly, the rubber ring will be pressed between the inner corner of
the disc and flange, forming a completely air tight joint.
The said disc is fitted in the cap in such a manner that while they cannot be
easily separated yet the cap can turn relatively to it, so as to avoid any stretching
or tearing action on the india-rubber ring. This can be conveniently effected by

page_text: nipping or contracting the metal of the cap over the upper flange of the disc
sufficiently to prevent its removal, whilst avoiding a rigid connection.
As shown in Fig. 2 the arrangement is somewhat similar, but the groove a is
formed on the top surface of the bottle, and the disc instead of being provided with
a flange is formed with the enlarged portion e' which fits within the top of the

the joint.
In the arrangement shown in Fig. 3 the rubber ring D instead of being placed
in a groove at the outer corner of the bottle, is placed in a similar groove a at the
inner-corner, and the enlarged part c¹ is rounded at the corner so as to press against
the rubber ring when the cap is screwed down.
As shown in Fig. 4 the outer edge of the bottle a³ is bevelled and the groove a³
is formed at the lower portion of this hevelled part. The flange somewhat similar
to that shown in Fig. 1 is also formed with its inner side bevelled or sloped so that
it will press on the rubber ring at an angle.
In the arrangement shown in Fig. 5 the top of the bottle is formed with the
groove a of some denth within which the rubber ring is completely hidden. The
dise C is formed with the small flange e which is adapted to enter within the
groove and form the joint by pressing on the rubber ring.
As shown in Fig. 6 the arrangement is reversed the disc being formed with the
double or grooved flange e, within which the rubber ring is placed and the top
of the bottle is formed with the flange a entering into the groove.
The arrangement shown in Figs. 7 and 8 are similar to those above described,
but in place of having the flanges and channels straight in cross section, they are
shown at an angle. Instead of the angle heing directed inwardly as shown in
these figures, it is obvious that the channels and flanges may extend in the
opposite direction. The rubber band also may be of any desired shape in cross
section. either square or round.
Fig. 9 shows an arrangement in which the rubber ring D is fitted around the
central part of the loose dise instead of to the top of the bottle. To keep the
ring in place the lip is provided or the ring may he caused to lie in a groove.
The shape of the shoulder on the top of the bottle may be varied as found desirable,
the ring in the arrangement shown being compressed between bevelled surfaces.
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:
