PROVISIONAL SPECIFICATION.
Improvement in and relating to Bottles and Jars.
I, WILLIAM PAGET HOBLYN, of The Fir Hill, St. Columb, in the County of
Cornwall, J.P. for Cornwall, do hereby declare the nature of this invention to be
as follows:-
.
My invention has for its object both to prevent the contents of bottles and jars
of glass or earthenware from being tampered with and to effect the hermetic
sealing thereof. For these purposes I form on the ordinary mouth of the bottle or
jar an extension or chamber open at top and of somewhat larger size internally
than the mouth of the bottle, so that the ordinary cork or stopper can be readily
inserted in the mouth through the extension.
At any point of the outer surface of the extension I form a sufficiently deep
circular groove round the same to allow of the part beyond the groove being
readily separated by a moderate blow.
The bottle having been filled with the liquid, and the cork inserted, the opening
of the extension is then closed by a stopper or cap of glass or other suitable
material coated with a suitable cement so that when this has hardened the stopper
cannot be extracted.
For gaining access to the contents of the bottle the upper part of the extension
has to be separated from the bottle by a moderate blow, as described, and the cork
is then extracted in the usual manner..
For additional security, the stopper or cap may be made with projecting studs
and the extension be formed with bayonet-joint grooves or vice versa so that when
the cap is inserted coated with cement, and then turned slightly round by means of
a key, it will be securely held in the extension. In this case, if the liquid in the
bottle be aerated under pressure, the stopper or cap may be made with a downward
extension bearing upon the cork, so as to support this against the internal
pressure.
The said extension is by preference made in one piece with the bottle or jar at
the time of manufacture.
It may however be applied to existing bottles by fitting with its lower open end
over the mouth of the bottle or jar, being securely cemented thereto.
For preventing the accidental fracturing of the extension, particularly when the
bottles have to be transported long distances, I provide a light cap of metal,
papier machè or other suitable material to be fitted over the extension.

☐ Improvement in and relating to Bottles and Jars.
I, WILLIAM PAGET HOBLYN, of The Fir Hill, St. Columb, in the County of
0 Cornwall, J.P. for Cornwall, 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 :—
My invention has for its object both to prevent the contents of bottles and jars
of glass or earthenware from being tampered with and to effect the hermetic
1

page_text: sealing thereof. For these purposes I form on the ordinary mouth of the bottle
or jar an extension or chamber open at top and of somewhat larger size internally
than the mouth of the bottle, so that the ordinary cork or stopper can be readily
inserted in the mouth through the extension.
At any point of the outer surface of the extension I form a sufficiently deep
circular groove round the same to allow of the part beyond the groove being
readily separated by a moderate blow.
The bottle having been filled with the liquid, and the cork inserted, the opening
of the extension is then closed by a stopper or cap of glass or other suitable
material coated with a suitable cement so that when this has hardened the stopper
cannot be extracted.
For gaining access to the contents of the bottle the upper part of the extension
has to be separated from the bottle by a moderate blow, as described, and the cork
is then extracted in the usual manner.
For additional security, the stopper or cap may be made with projecting studs
and the extension be formed with bayonet-joint grooves, or vice-versa, so that
when the cap is inserted coated with cement, and then turned slightly round by
means of a key, it will be securely held in the extension. In this case, if the
liquid in the bottle be aerated under pressure, the stopper or cap may be made
with a downward extension bearing upon the cork, so as to support this against the
internal pressure.
The said extension is by preference made in one piece with the bottle or jar, at
the time of manufacture.
It may however be applied to existing bottles by fitting with its lower open end
over the mouth of the bottle or jar, being securely cemented thereto.
For preventing the accidental fracturing of the extension, particularly when the
bottles have to be transported long distances, I provide a light cap of metal, papier
machè or other suitable material to be fitted over the extension.
The accompanying drawing shews by way of example, some arrangements of
my invention as applied to bottles and jars. Fig. 1 shews a vertical section and
Fig. 1 a plan of a bottle neck on which is formed the extension A, in the opening
of which is provided a seat B for the reception of a plug C, shewn detached at the
section Fig. 2. The sides of the seat B are slightly undercut and the periphery
of the plug is correspondingly bevilled, the diameter of the bottom of the plug
being such that it will just enter through the opening of the extension, so that
when the plug is in place as at Fig. 1, a small annular interstice will exist
between it and the extension A, which is filled in with a suitable cementitious
matter applied to the plug before introducing it. Thus it will be seen that when
the cement has hardened the plug will be held securely in position in the extension
and will withstand considerable internal pressure. On the extension A is formed
either both an internal and an external circular groove D D' as at Fig. 1, or only
an external groove D as at Fig. 2, leaving in either case only a comparatively thin
annular portion of material connecting the upper part of the extension to the
lower part as shewn by dotted lines at Fig. 1A so that by a slight blow the top
part can be separated, leaving the cork X exposed. The cork is by preference
made to project sufficiently to bear against the underside of the plug C, so as to
be supported thereby to resist any internal pressure to which the contents of the
bottle are subjected.
The internal diameter of the extension A is by preference made slightly larger
in diameter than the opening of the neck of the bottle, so that the cork can pass
freely through it when being inserted into the neck of the bottle.
Although I prefer to make the plug B with bevilled sides as described, it may
also be made cylindrical, fitting a cylindrical seat in the extension, the cement
when hardened being sufficient to hold it securely. In some cases the plug may
be beld still more securely against internal pressure by forming the extension A
with a bayonet joint, as shewn in section and plan at Figs. 3 and 4, the extension A
being formed with two vertical grooves E with lateral enlargements while the plug

page_text: is formed with two studs F that pass down the grooves and then, by turning the
plug by means of a key inserted in a recess G, are made to enter the lateral
enlargements, the grooves E being then filled with cement so as to hold the plug
in that position; or the surfaces of the plug and the seat might be made of a
slightly spiral cam shaped, as at Fig. 5, so that when the plug is inserted and
turned slightly, it will be jammed tight in the seat, in which position it is secured.
by the cement with which it is coated and by filling the spaces H with cement. I is
the before mentioned protecting cap made to fit tightly over the neck of the bottle..
Fig. 6 shews the invention applied to a jar.
Fig. 7 shews the application to an ordinary bottle neck of a separate extension
piece K with plug L secured to the bottle by cement.
Having now particularly described and ascertained the nature of this inven--
tion and in what manner the same is to be performed, I declare that what I
claim is :-
Providing bottles and jars with an extension to the neck, adapted to be closed.
by a plug or stopper secured by cement or other means, and having one or more
circular grooves so that while the extension effectually protects the contents of the
bottle against being tampered with, it can be readily separated from the bottle by
a slight blow when the contents are to be used, substantially as described.
