I ALBERT JULES THEODORE WILD of N° 51 Great Dover Street Borough in
the County of Surrey Civil Engineer do hereby declare the nature of my inven-
tion for "IMPROVEMENTS IN BOTTLES: AND SIMILAR VESSELS AND IN STOPPERS
THEREFOR "to be as follows:-
An improved external screw neck bottle cast and finished with an apparatus or
tool as stated in my provisional Specification N° 10719-1884 and improved
metallic screw capsule used in conjunction therewith by which arrangement great
strength is obtained. To carry out my invention I form an external seating above
the thread of the neck of the bottle or an internal seating in the neck of the bottle
of any suitable depth so as to allow a rubber ring or any other material to be fixed'
or lodged on the seating or neck of the bottle by the capsule for the purpose of'
medically sealing. the bottle. In the capsule I form a groove or indentation in'
such a manner as to hold a Washer or rubber ring or other suitable material above
the thread therein so that the capsule bites on the thread of the bottle first and
the rubber ring or other material fixes externally round the seating or internally
on the seating thus making an absolute air tight joint and preventing any liquid'
coming in contact with such washer. In some cases I may form an indentation in
the capsule which would be internally applied in the neck of the bottle but adapted'
most essentially for the purpose of strengthening the capsule from over pressure.

page_text: My invention relates to bottles and similar vessels and stoppers therefor, and
comprises various improvements hereinafter described.
In the accompanying drawing-
Figure 1 is a side elevation of the neck of a bottle made according to my said
invention.
Figure 2 is a vertical central section of my improved stopper.
Figure 3 is a vertical central section shewing the bottle-neck.with the stopper
applied thereto.
Figure 4 is a vertical central section showing a slight modification of my
invention, and
Figure 5 is a sectional elevation shewing a further modification thereof.
a indicates the neck of the bottle, which is formed with an external screw-
thread a' and an external seating a². This seating is L-shaped in transverse
section. The said seating and screw-thread are formed by means of a suitable tool
or apparatus. b is the stopper, which consists of a cover or capsule with an
internal screw-thread 61, corresponding with the screw-thread on the bottle-neck,
and a groove or channel 63, in which is inserted a disc c of cork, and a ring or
washer d of india-rubber or other suitable material. The groove or channel 6ª is
of such depth that, when the disc c and ring d are inserted therein, they will be
held in position in the capsule.
When the stopper is screwed upon the neck of the bottle, the ring or washer dis
forced down upon the seating a³, so that its inner surface and its lower surface are
pressed tightly against the said seating, as shown in Figure 3; and the cork disc c
is forced down upon the mouth of the bottle, as also shewn in this figure. It will,
therefore, be seen that the escape of liquid from the bottle will be prevented by the
cork disc c, whilst the ring or washer d will ensure the air-tight closure of the
bottle. It will be seen, moreover, that, when the bottle is thus closed, the liquid
therein cannot come in contact either with the india-rubber ring, or with the block
tin or other material of which the cover or capsule is made, but can only come in
contact with glass and cork, as in bottles closed by ordinary corks. In cases where
it is not necessary to prevent the contact of the liquid with the india-rubber, I
sometimes dispense with the cork disc c.
If necessary I provide for strengthening the capsule, to enable it to withstand
considerable internal pressure, by making it with a central depression, which will
project slightly into the mouth of the bottle.
In some cases, instead of forming the bottle-neck with an external seating,
I make the same with an internal seating a³, Figure 4, and I make the stopper b

page_text: with a central depression 63 around which is placed the ring or washer d. When
this stopper is screwed upon a bottle-neck, the washer d is forced down upon the
seating a³, so that its outer surface and its lower surface are pressed tightly against
the said seating, as shewn in Figure 4.
I sometimes make my stopper as shewn in Figure 5, in which e is a plug of glass
or other suitable material, and f is a ring of cork fitted thereon. This plug is made
with a head e' which fits into the groove or channel 6* in the capsule. When this
stopper is screwed upon a bottle-neck, the plug e enters the mouth of the bottle
and the cork f is pressed against the interior of the bottle-neck. This form of
stopper is well adapted for bottles to be used for champagne, as the plug e will not
be rotated, when the capsule is unscrewed from the bottle-neck; but will be forced
out in the direction of its axis by the act of unscrewing the capsule. The stopper
can therefore be removed, when necessary in the manufacture of the champagne,
without disturbing the sediment which accumulates upon the interior of the
stopper.
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
First. A stopper consisting of a cover or capsule having an internal screw-thread
or similar means for securing it upon a bottle or other vessel, and an elastic ring or
washer fitted in a groove or channel in the said capsule and adapted to bear upon
an external seating on the neck of the bottle or vessel, (with or without the cork)
all substantially as, and for the purposes, set forth.
Second. A bottle or similar vessel formed with an external seating substantially
as shewn in Figure 1 of the drawing for use in combination with the said
stopper.
Third. The modification of my invention wherein I employ an internal seating
on the bottle-neck, and make the stopper with a central depression, substantially
as described with reference to Figure 4 of the drawing.
Fourth. The modification of my invention wherein I employ a glass or other
plug arranged within the capsule and provided with a ring of cork, substantially as
described with reference to Figure 5 of the drawing.
