PROVISIONAL SPECIFICATION.
Jars and similar Receptacles for Sterilized Milk and similar
preparations.
I DAN RYLANDS of Shepcote, Stairfoot, near Barnsley in the County of York,
Glass Bottle Manufacturer do hereby declare the nature of this invention to be as
follows:-
:―
My present invention has for its object the manufacture of jars for sterilized
milk and other preparations in such a way that the said jars are sealed up perfectly;
and also so that it is quite easy to break the vacuum and to pour out the milk from
the said jars without removing it to another vessel.
Another object of my invention is that the sterilized milk or other fluid intended
for child nourishment can be drawn from the jar without having to be first
transmitted into another feeding bottle.
The way in which I consider this can best be worked out is by so altering the
shape of the plunger and of the top of the parison mould that an oval or other shape
spouted jar is formed; and the special point of novelty in a jar made according to
my present invention is that I form all around the outside of the jar and near to
the top of the mouth a ledge for receiving a washer made of india rubber or other
suitable substance.
I also use a strip of paper for going inside the jar lid. The lid is pressed of an
exact internal configuration whether oval or round or other shape and has the same
spouted form as the jar, so that it nicely fits over the spouted mouth of the jar, and
comes down upon the washer resting on the ledge.
In any suitable place in the top of the lid I form or make a hole of a suitable
shape for receiving either a small piece of glass and wax or for receiving a piece
of wadding or other suitable substance; and this hole is intended to remain open
or to have in it a piece of suitable wadding during the time that the milk is being
heated to the proper heat for sterilizing it. After the milk has been so heated the
said hole is closed either by means of sealing wax or other suitable substance, and
where so preferred a piece of glass or other substance is dropped in the hole before
the sealing wax is put in.
After the milk has been heated sufficiently hot to sterilize it and as the hole
referred to in the lid will have been closed before the contents of the jar have
condensed, the condensing which follows will result in a vacuum in the jar, and
the atmospheric pressure thus brought upon the lid will hold the lid in air-
tight position on the rubber washer before referred to. When it is desired to
remove the lid it is only necessary to break the vacuum by inserting a sharp pointed
instrument into the ring of india rubber and prising up.
Where the contents of the jar are intended for the use of infants, the mouth
of the jar or bottle instead of being spouted may be any other suitable shape,
but it will still be formed having the outer ledge at a slight distance below
the mouth; and the glass cap will also be made to suit the outside configuration
of the mouth. On this ledge there may be formed a suitable outer screw or
suitable inclines on which may be screwed a metal or other cap having an india
rubber tube and a glass tube as used for feeding bottles. I form in this glass cap
a hole sufficiently large to receive the tube, into which hole I insert a cork or
other suitable packing, and through which packing a hole is made to allow of the
egress of the steam or hot air during the time that the milk is being sterilized.
After the milk has been sterilized this hole is sealed up, the result being as before
described, namely that the vacuum is sufficient to hold the lid in airtight position.

page_text: In forming the hole in the lid for the feeding bottle I make it such a shape as it
will allow for any ingress of air that may be necessary to enable the infant to
easily withdraw the contents of the bottle when the tubes are affixed thereto.
In some cases I form the cap and the outside of the jar in such a way that the
tube of glass and the india rubber tube and cap usually attached to feeding bottles
can be adapted to this bottle without removing the glass cap which has been used
in the sterilizing process..
It will be well understood that during the sterilizing process the lid of the jar or
bottle is held in proper position by means of clips having suitable screw or other
attachment... ·

COMPLETE SPECIFICATION.
Jars and similar Receptacles for Sterilized Milk and similar
preparations.
I DAN RYLANDS of Shepcote Stairfoot near Barnsley in the County of York,
Glass Bottle Manufacturer do hereby declare the nature of this invention and in
what manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement:-
My present invention has for its object the manufacture of jars for sterilised
milk and other preparations in such a way that the said jars are sealed up perfectly
and also so that it is quite easy to break the vacuum and to pour out the milk from
the said jar without removing it to another vessel.
Another object of my invention is that the sterilised milk or other fluid intended
for child nourishment can be drawn from the jar without having to be first trans-
mitted into another feeding bottle.
The way in which I consider this can best be worked out is by so altering the
shape of the plunger and of the top of the parison mould that an oval or other
shape spouted jar is formed; and the special point of novelty in a jar made according
to my present invention is that I form all around the outside of the jar and near to
the top of the mouth a ledge for receiving a washer made of india rubber or other
suitable substance.
I also use a strip of paper for going inside the jar lid. The lid is pressed of an
exact internal configuration whether oval or round or other shape, and has the
same spouted form as the jar, so that it nicely fits over the spouted mouth of the jar,
and comes down upon the washer resting on the ledge.
In any suitable place in the top of the lid I form or make a hole of a suitable
shape for receiving either a small piece of glass and wax or for receiving a piece
of wadding or other suitable substance; and this hole is intended to remain open or
to have in it a piece of suitable wadding during the time that the milk is being
heated to the proper heat for sterilising it. After the milk has been so heated the
said hole is closed either by means of sealing wax or other suitable substance, and
where so preferred a piece of glass or other substance is dropped in the hole before
the sealing wax is put in.
After the milk has been heated sufficiently hot to sterilise it and as the hole
referred to in the lid will have been closed before the contents of the jar have
condensed, the condensing which follows will result in a vacuum in the jar, and the
atmospheric pressure thus brought upon the lid will hold the lid in airtight position
on the rubber washer before referred to. When it is desired to remove the lid it
is only necessary to break the vacuum by inserting a sharp pointed instrument into
the ring of india rubber and prising up.
Where the contents of the jar are intended for the use of infants, the mouth of
the jar or bottle instead of being spouted may be any other suitable shape, but it
will still be formed having the outer ledge at a slight distance below the mouth :

page_text: and the glass cap will also be made to suit the outside configuration of the mouth.
On this ledge there may be formed a suitable outer screw or suitable inclines on
which may be screwed a metal or other cap having an india rubber tube and a
glass tube as used for feeding bottles. I form in this glass cap a hole sufficiently
5 large to receive the tube, into which hole I insert a cork or other suitable packing,
and through which packing a hole is made to allow of the egress of the steam or
hot air during the time that the milk is being sterilised. After the milk has been
sterilised this hole is sealed up, the result being as before described, namely that
the vacuum is sufficient to hold the lid in airtight position. In forming the hole in
the lid for the feeding bottle I make it such a shape as it will allow for any ingress
of air that may be necessary to enable the infant to easily withdraw the contents
of the bottle when the tubes are affixed thereto.
In some cases I form the cap and the outside of the jar in such a way that the
tube of glass and the india rubber tube and cap usually attached to feeding bottles
can be adapted to this bottle without removing the glass cap which has been used
in the sterilising process.
It will be well understood that during the sterilising process the lid of the jar or
bottle is held in proper position by means of clips having suitable screw or other
attachment.
In the accompanying drawings,
Fig. 1 is a sectional elevation, Fig. 2 an elevation, and Fig. 3 a plan view of ‘a
spouted jar as contemplated by my invention.
Fig. 4 is a plan view of the jointing ring which is of rubber or other suitable
material.
'
Figs. 5 and
are elevations in section showing the formation of the blowing
mould, the parison mould, and the pressing plunger most suitable for the production
of the spouted jar illustrated by Figs. 1 to 3.
In Fig. 7 a jar is shown in sectional elevation well adapted for the sterilisation
and preservation of milk or other fluid intended for the nourishment of children,
and so constructed that the sterilised milk can be drawn from the jar without
having to be poured into a feeding bottle.
In Fig. 8 the glass lid of the jar has been removed and the metal lid and glass
and rubber tube substituted making an efficient feeding bottle.
Fig. 9 is an external elevation of Fig. 8.
In Fig. 10 a jar is shown provided with a glass lid the lid being formed with
a mouth for the reception of the sealing cork, the lid being securely held in
position and attached to the jar by means of the screwed annular metal rim shown.
Fig. 11 illustrates the jars with the sealing cork removed and the glass and
rubber tube ordinarily used with feeding bottles in position as for use,
In Figs. 1. 2 and 3, a is the body of the jar formed at b into a surrounding ledge
or projection for the reception and seating of the rubber or other jointing ring c;
is the spout of the jar, e a rim of paper or cork, f the glass cap or lid the internal
onfiguration of which corresponds to the outer formation of the raised rim g
orming the mouth of the jar, and h an aperture formed in the glass lid. The
terilisation of the milk and the setting up and maintaining of a vacuum in the
terior of the jar is effected in the following manner.
he glass lid with its internal lining of cork or paper being in position as shown,
The jointing ring c and
nd the lid being held down firmly on the jar by means of clips having screw or
ther suitable attachments, the now closed jar and its contents are placed in a
itable heating bath and the contents raised to the heat necessary for the
erilisation of the milk. This being done, the jar is removed from the bath and
e aperture closed by means of sealing wax or other suitable substance, or where
preferred a piece of glass or cork is placed in the aperture before the application
the sealing wax. The jar being now hermetically closed will result in the
tting up of a vacuum in the interior of the jar as the contents cool when the
ternal pressure of the atmosphere acting on the upper surface of the lid and
e bottom of the jar will be amply sufficient to compress the jointing ring ‍and
c

page_text: make tight and effectual joint against the readmittance of the outer air. When
it is desired to remove the lid it is only necessary to break the vacuum by inserting
a sharp pointed instrument into the jointing ring and levering the lid away from
the jar.
Figs. 1 to 3 show my invention as applied to jars of an oval form, but it will be
evident that the invention is applicable to round or other formation of jars.
In Figs. 5 and 6 the formation and arrangement of the blowing mould, the parison
mould, pressing plunger, and mould bottom, most suitable for the production of the
above-described spouted jar are shown.
Fig. 5 represents the various parts in the position they are caused to assume
during the parison forming or pressing process.
In Fig. 6 the blowing mould, mould cover, and the mould bottom are in position
for the blowing and completion of the finished jar; a is the blowing mould, b the
parison mould formed as shown, c the pressing plunger, d the blowing mould bottom,
f the blowing mould cover, g the parison jar, the blown and completed jar. The
manner of operating the various parts is after the manner of the pressing and
blowing process now so well known; that is, firstly in the pressing into form of the
parison bottle as shown by Fig. 5, and secondly in the expanding and blowing of
the parison into the completed jar as shown by Fig. 6. It will be seen that the
pressing plunger is suitably formed at i for the pressing and formation of the
interior portion of the spout, the blowing mould at forming the exterior portion.
In Fig.
an hermetically sealed jar suitable for the sterilisation and preservation
of milk or other similar fluid is shown. From the illustration it will be seen that the
encircling ledge a is provided with a raised screw thread on its outer circumference
and that the glass lid c is formed at d into a mouth portion sealed by the cork e
and sealing wax f.
Fig. 8 shows the previously-described jar converted into an infant's feeding
bottle by the removal of the glass lid c, and the substitution of the metal cap g
which is internally threaded at h for engaging with the screw thread carried by the
outer circumference of the encircling ledge a. The metal cap is formed with a
mouth portion i for the reception of the ordinary feeding bottle tube arrangement.
In Figs. 10 and 11 a jar is shown also intended for the sterilisation and
preservation of milk and which can also very readily be converted into an infants
feeding bottle, a is the glass cap formed ab into a mouth portion sealed by the
cork cand sealing wax d. The glass lid in this arrangement is held in position and
securely attached to the jar by the internally threaded metal rim e engaging with
the raised screw threads f formed on the outer circumference of the encircling
ledge g as shown. It will be seen that to convert this jar into a feeding bottle it is
only necessary to remove the sealing cork c and substitute the ordinary glass and
rubber tube arrangement.
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 I
claim is :
1. In an oval or other shaped jar for containing sterilised milk and other similar
preparations, the combination of the spout d and the projecting ledge & substantially
as and for the purpose described and illustrated at Figs. 1, 2, 3 and 4.
2. In the manufacture of the improved jar mentioned in the preceding claim the
use of the pressing plunger formed at i for the pressing and formation of the
interior portion of the spout, and the adaptation of the blowing mould at j for
forming the exterior portion of the spout as described and illustrated by Figs. 5
and 6.
3. The construction of jars as illustrated at Figs. 7, 8 and 9 so that the hermeti-
cally sealed jar containing sterilised milk or similar preparations can be converted
into an infants feeding bottle in the manner herein described or any mere modification
thereof:
4. The modified jar for containing sterilised milk or similar fluids as shown at

page_text: Fig. 10, capable of being converted into an infants feeding bottle by the removal of
the sealing cork c and the substitution of the ordinary glass and rubber tube without
the removal of the glass lid a as illustrated by Fig. 11.
Dated this 3rd day of October 1892.
