Improvements in Stoppering Bottles and Jars.
I, STAFFORD HILL, of the Firm of G. V. De Luca Hill & Co., of 6 and
7 Long Lane in the City of London, Glass Bottle Manufacturers and Merchants,
do hereby declare the nature of this invention to be as follows:-
My invention relates to that class of stoppers in which a rigid cap rests on a
rubber or other ring which wben compressed forms a close joint between the cap
and the bottle and in which the cap is intended to be hold firmly down by the
atmospheric pressure and which cap is further secured against accidental displace-
ment by an appropriate device.
Attempts have been 'made to construct such stoppers in which the cap is held
down on the ring (besides the atmospheric pressure) by a screw cap or ring, but such
screw caps or rings are found in practice to become fixed by rust or dirt so as to be
very difficult to remove when the bottle has to be opened.
Now my invention is intended to provide a more perfect stopper than those
heretofore in use, which may be closed with great facility and certainty, which is
thoroughly reliable and is not liable to accidental displacement, and which is easily
and quickly opened.
According to my invention which I propose to designate the "Look-vacuum "
stopper I construct the nozzle of the jar or bottle with an exterior annular rim or
shoulder and below that one or more preferably three slightly inclined grooves
which serve to receive corresponding parts forming a bayonet joint.
The cap make of sheet metal, preferably tinned or bronzed sheet iron, or of
solid tin, the latter although it costs more is preferable for the reason hereinafter
explained, and I form the said cap of diameter to fit easily but closely over the
nozzle of the hottle and of depth to reach to or nearly to the shoulder, and with
its lower edge turned outwards forming a flange adapted to rest on and compress
a rubber ring placed on the shoulder. Over this cap I place a sheet metal
cylindrical ring the upper edge of which is turned inwards so as to engage with
the flange of the cap and the lower part of which is provided with one or more,
preferably three inwardly projecting studs or indentations to engage in the bayonet
joint grooves before mentioned and so that when the said ring is placed over the
cap and rotated a fraction, say, for instance a quarter of a revolution, the studs or
indentations engaging in the inclined grooves draw, the ring and with it the cap
downwards and compress the rubber ring so as to secure an air tight joint.
In actual use it is intended that the cap and rubber ring and the bayonet joint
ring shall be loosely fitted on, that the air shall then be expelled from the bottle
by boiling (or by exhaustion or otherwise) that the bayonet joint ring shall then
be rotated so as to compress the rubber ring between the cap and the shoulder,
that the bottle be then left to cool, or otherwise the atmospheric pressure
allowed to act on the cap which is thereby pressed with great force on the rubber
ring.
The joint thust produced is absolutely air tight and is so protected and secured
by the bayonet joint ring that accidental displacement is practically impossible.
The ring is not likely to become fixed, and when this is removed the cap is easily
lifted, without being destroyed, by the insertion of the end of a lever, say for
instance the blade of a knife, under the flange of the cap, by, which the cap may

to be lifted off.
When the cap is made entirely of tin of appropriate thickness the atmospherio
pressure bends the top of the cap inwards and thereby slightly contracts the
annular portion of it so that it closes in on and bites the glass nozzle so effectually
that the contents of the bottle is cut off entirely from access to the rubber ring,
which in some cases is a distinct advantage,
The bottles and stoppers made as hereinbefore described are more perfect than
any others heretofore invented, inasmuch as they can be produced at a very
moderate cost, they are extremely easy to manipulate, they are very secure, and
easily opened, and they possess this combination of advantages to a greater extent
than any others heretofore produced.

oppering Bottles and Jars.
I, STAFFORD HILL, of the Firm of G. V. De Luca Hill & Co. of 6 and
7 Long Lane in the City of London, Glass Bottle Manufacturers and Merchants,
do hereby declare the nature of the said 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 that class of stoppers in which a rigid cap rests on a
rubber or other ring which when compressed forms a close joint between the cap
and the bottle and in which the cap is intended to be held firmly down by the
atmospheric pressure and which cap is further secured against accidental displace-
ment by an appropriate device.
Attempts have been made to construct such stoppers in which the cap is
held down on the ring (besides the atmospheric pressure) by a screw cap or
ring, but such screw caps or rings are found in practice to become fixed by rust or
dirt so as to be very difficult to remove when the bottle has to be opened.
Now my invention is intended to provide a more perfect stopper than those
heretofore in use, which may be closed with great facility and certainty,-which
is thoroughly reliable and is not liable to accidental displacement, and which is
easily and quickly opened.
In the accompanying drawings
Fig. 1, is an elevation of one of my improved bottles or jars with the rubber
ring and the cover removed:
Fig. 2, is an elevation of the same with cover on, a small portion thereof being
represented as broken away to show the position of the rubber ring:
Fig. 3, is an elevation shewing the upper portion of the bottle and closing
apparatus in section.
According to my invention which I propose to designate the "Lock-vacuum
stopper construct the nozzle of the jar or bottle A with an exterior annular
rim or shoulder b and below that one or more, preferably three, slightly inclined
grooves o which serve to receive corresponding parts of the cover thereby forming
a bayonet joint.
The cap D I make of sheet metal, preferably tinued or bronzed sheet iron, or
of solid tin, the lattor although it costs more is preferable for the reason
hereinafter explained, and I form the said cap of diameter to fit easily but closely
over the nozzle of the bottle and of depth to reach to or nearly to the shoulder b,
and with its lower edge turned outwards forming a flange d adapted to rest on

page_text: and compress a rubber ring placed on the shoulder b. Over this cap I place
a sheet metal cylindrical ring g the upper edge of which is turned inwards so as to
engage with the flange d of the cap D and the lower part of which is provided
with one or more, preferably three, inwardly projecting studs or indentations to
engage in the bayonet joint grooves c before mentioned, and so that when the said
ring g is placed over the cap D and rotated a fraction, say, for instanco a quarter
of a revolution the studs or indentations engaging in the inclined grooves
draw the ring y and with it the cap D downwards and compress the rubber ring
so as to secure an air tight joint. A groove & immediately above the shoulder b
serves to retain the rubber ring in its place before the cover is put on.
g
In actual use it is intended that the cap D and rubber ring f and the ring g
shall be loosely fitted on (that is to say so that the flange of the cap D is
slightly pressed on to the rubber ring), that the air shall then be expelled from
the bottle by boiling (or by exhaustion or otherwise) that the ring shall then
be rotated so as to compress the rubber ring between the flange d of the cap D
and the shoulder b, that the bottle be then left to cool, or otherwise the
atmospheric pressure allowed to act on the cap D which is thereby pressed with
great force on the rubber ring, after which the ring g should be further tightened.
The joint thus produced is absolutely air tight and is so protected and secured
by the ring g that accidental displacement of the cover or rubber ring is
practically impossible. The ring 9 is not likely to become fixed, or if it should
become rusted it is easily started by reason of the small surfaces of the studds
on indentations h, and when this is removed the cap D is easily lifted, without
being destroyed, by the insertion of the end of a lever, say for instance the blade
of a knife, under the flange of the cap, by which the cap may be sufficiently
raised to admit of the ingress of air after which the cap needs only to be lifted
off; or it may be at once released by being pricked so as to admit the air.
When the cap D is made entirely of tin of appropriate thickness the atmospheric
pressure bends the top of the cap inwards and thereby slightly contracts the
annular portion of it so that it closes in on and bites the glass nozzle so effectually
that the contents of the bottle is cut off entirely from access to the rubber ring,
which in some cases is a distinct advantage.
The bottles and stoppers made as hereinbefore described are more perfect than
any others heretofore invented iuasmuch as they can be produced at a very
moderate cost, they are extremely easy to manipulate, they are very secure, and
easily opened, and they possess this combination of advantages to a greater extent
than any others heretofore produced.
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 what 1
claim is :-
1. The improvements in stoppering bottles and jars substantially as hereinbefore
described and shown in the drawings.
2. A jar or bottle and stoppering mechanism consisting of a jar or bottle
having a shoulder such as b on which a rubber ring such as f is compressed by
the flanged edge d of a cover such as D by atmospheric pressure assisted and
secured against accidental displacement by a ring such as g having studds or
indentations such as h which engage in inclined grooves such as a substantially
as and for the purpose described and as shewn in the drawings.
3. In an arrangement or mechanism for stoppering bottles and jars the com-
bination of a bottle or jar provided with a shoulder b, inclined grooves o, and
groovek, with a rubber ring , cap D with Hange d, ring g with studds or
indentations h, all substantially as described and shown.
