Vessels for Containing Preserved Food.
1, GEORGE FREDERICK REDFERN, of the General Patent Office, No. 4 South Street,
Finsbury, in the county of Middlesex, Patent Agent, do hereby declare the nature of
this invention (a communication from abroad by Joseph Petit, of Bordeaux, in the
republic of France, Engineer) to be as follows:-
Hitherto the great difficulty of stoppering glass bottles has been the sole cause of
tin boxes or canisters being employed.
The great increase in the manufacture or preparation of all kinds of preserved foods
has caused the consumer to seek amongst these products that which nearest approaches
perfection.
One of the essential conditions for obtaining such perfection depends as much on
the receptacles employed for containing the preserves as on the hermetic closing and
for this reason glass receptacles have been preferred to all others.
But in making use of such recoptacles there has been hitherto great difficulty n
stoppering or closing them in obtaining the desired conditions of resistance and of
impermeability, that is to say: the perfect hermetic closing of glass receptacles.
In carrying out the invention I make the upper part of the neck of the receptacle
with a ring upon which is placed an india rubber washer resting on a glass rim
or flange in which is a groove for receiving the iron wire between the metal
capsule and the glass for effecting the unstoppering in an easy manner. The
metal capsule is constructed with a shoulder or recess to receive the washer and to
perfectly enclose the ring at the upper part of the neck of the receptacle. The
capsule is provided on the side with an oval hole which allows, when once the
stoppering has been effected, of a wire being passed therethrough, the said wire
having an eyelet at its end; after the stoppering the wire is introduced into the hole
and passes round the neck and out at the hole through which it entered; it is then
bent over the capsule so as to form a hook or clasp; the eyelet is then turned over
the end hooked or clasped over the capsule.
The stoppering is effected by means of a special machine. For this purpose the

page_text: india-rubber washer or ring is placed on the rim, flange or shoulder of the receptacle
in such a manner that it may enter the capsule which is pressed out so that only the
shoulder in which the india rubber washer is situated is subjected to pressure; the
receptacle is then placed on the machine. When pressure is exercised the rubber
washer or ring is firmly compressed on all four of its sides, namely, on two by the
glass and on the two others by the capsule. Whilst the pressure is being effected the
edge of the capsule is turned down all round under the lower part of the rim, flange
or shoulder of the receptacle by means of the machine. In this manner the rubber
washer or ring remains firmly compressed and fills all recosses and forms a joint
which is absolutely hermetic.
For preserves of a fatty nature a sheet of vegetable parchment or pure tin is placed
above the india rubber washer.
In order to unstopper the recoptacle it is merely necessary for a person to pass
through the eyelet any suitable object and to pull this end of the wire towards himself
or herself completely round the neck.

I, GEORGE FREDERICK REDFERN, of the firm of G. F. Redfern & Co., the General
Patent Office, No. 4 South Street, Finsbury, in the County of Middlesex, Patent
Agent, do hereby declare the nature of this invention (a communication from abroad
by Joseph Petit, of Bordeaux, in the republic of France, Engineer) and in what
manner the same is to be performed to be particularly described and ascertained in
and by the following statement :-
Hitherto the great difficulty of stoppering glass bottles has been the sole cause of
tin boxes or canisters being employed.
The great increase in the manufacture or preparation of all kinds of preserved
foods has caused the consumer to seek amongst these products that which nearest
approaches perfection.
One of the essential conditions for obtaining such perfection depends as much on
the receptacles employed for containing the preserves as on the hermetic closing and
for this reason glass receptacles have been preferred to all others.
But in making use of such receptacles there has been hitherto great difficulty in
stoppering or closing them in obtaining the desired conditions of resistance and of
impermeability, that is to say: the perfect hermetic closing of glass receptacles.
In order to enable the invention to be fully understood I will proceed to describe
the samo by reference to the accompanying drawing in which figure 1 is a transverse
section of a capsule forming part of my improvements; figure 2 is a plan of the
same; figure 3 is a transverse section of a jar provided with the improved capsule;
figure 4 is a perspective view of the upper part of a jar constructed according to my
invention with the capsule applied thereto and figure 5 is a similar view shewing the
capsule removed.
In carrying out the invention I make the upper part of the neck of the receptacle
with a ring over which is placed an india rubber washer B resting on a glass rim or
flango m in which is a groove n for receiving the iron wire between the metal capsule
and the glass for effecting the unstoppering in an easy manner.
The metal capsule
is constructed with a shoulder or recess S to receive the washer B and to perfectly
enclose the ring k at the upper part of the neck of the receptacle. The capsule is
provided on the side with an oval hole T which allows, when once the stoppering has
been effected, of a wire being passed there-through, the said wire having an eyelet L
at its end; after the stoppering the wire is introduced into the hole T and passes
round the neck and out at the hole through which it entered; it is then bent over the
capsule so as to form a hook or clasp the eyelet is then turned over the end hooked
or clasped over the capsule.
The stoppering is effected by means of any suitable machine. For this purpose the
india rubber washer or ring B is placed on the rim, flange, or shoulder m of the

page_text: receptacle in such a manner that it may enter the capsule which is pressed out so that
only the shoulder S in which the india rubber washer is situated is subjected to
pressure; the receptacle is then placed on the machine. When pressure is exercised
the rubber washer or ring B is firmly compressed on all four of its sides, namely, on
two by the glass and on the two others by the capsule. Whilst the pressure is being
effected the edge V of the capsule is turned down all round under the lower part of
the rim, flange or shoulder of the receptacle by means of the machine in any usual
manner, In this manner the rubber washer or ring remains firmly compressed and
fills all recesses and forms a joint which is absolutely hermetic.
For preserves of a fatty nature as india rubber is injuriously affected by contact
with fatty matters, at sheet of vegetablo parchment or pure tin is placed above the
india rubber washer.
In order to unstopper the receptacle it is merely necessary for a person to pass
through the eyelet any suitable object and to pull this end of the wire towards
himself or herself completely round the neck.
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
The improvements in stoppering or closing bottles, jars, and like vessels for
containing preserved food substantially as hereinbefore described and illustrated in
the accompanying drawing.
