Improvements in Feeding Bottles.
I, HEINRICH HERRMANN of Lauffen on the Neckar, Wurtemberg in the Empire
of Germany, Surgeon," 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. :―
The means hitherto employed for sterilising liquid food for infants only
partially fulfil their object, as firstly the sterilisation takes place in a different
vessel' to the one used for feeding and therefore the food has to be poured into
the latter after sterilisation and thereby comes in contact with the outer air, as is
also the case during the affixing of the teat. My improved feeding.
bottle
obviates in a simple manner this 'drawback by the sterilising of the liquid being
performed, by means of a water bath, in the feeding bottle itself, whilst the latter
is hermetically closed, a 'special arrangement being provided for allowing the
steam which may be formed to escape without admitting air. In order that only
purified air may be admitted, a small vessel perforated at the top is arranged on
the stopper, which vessel is filled with antiseptic wool or the like and which
communicates with the interior of the bottle by means of a small tube passing
through the stopper.
On the accompanying drawing
Figure 1 shows a vertical section of this improved sterilising feeding bottle';
Figure 2 a vertical elevation of same;
;
Figures 3 to 6 show on a larger scale the stopper and the device employed for
obtaining the sterilisation of tlie liquid and the purification of the air.
-
The feeding bottle A may have the ordinary form or any other suitable öne
and be provided or not with a scale for measuring the contents. The stopper B is
proferably made of india rubber, cork or the like. A tube C passes through the
stopper fitting airtight in the sanie, and reaches almost to the bottom of the
eans of which
bottle, which tube has a tap or cock c outside the plug by 'means
the tube C may be closed during the sterilisation of the contents of the bottle by
means of heat. One or more tube nozzles are attached to the cock c, on one of
which nozzles the suction tube is fixed. A second tube D extending 'ouly through
the stopper B' communicates by its outer, end and by means of a hollow inter-
mediate piece 'G with a small vessel. E filled with antiseptic wool, and having a
cover e and at its upper part a number of small openings, through which when
the lid is closed air is admitted into the upper part of the vessel and must pass
through the antiseptic wool before it can get into the feeding bottle.
A small light plate in the form of a valve, and which carries a light bäÏÏƒ
connected by means of thin wires, is arranged in the hollow intermediate pleco G
resting on the tube D and closing the same at the top and sliding on the short
tube of the vessel E. This arrangement of the plate F with its ball has for
its object to enable the steam evolved during the heating (sterilising) of the liquid
in the feeding bottle by lifting the plate to press the ball on the mouth of the
abort tube eand-to close this latter, so that the steam cannot penetrate into the
vessel E and moisten the antiseptio wool, but escapes to the outside through
the intermediate piece G and its discharge nozzle or tap g.
The sterilising of the liquid is performed by immersing the feeding bottle,
which for this object may be coated with wire network, in water, which cold at
firat is boiled for to hour. When the boiling (sterilising) of the liquid is
completed, the plate Feloses automatically and the ball drops down so the

page_text: opening at the bottom of the tube is free and air can pass through the vessel E
into the feeding bottle.
When it is intended to make use of the feeding bottle, the suction tube is
attached and the cock c opened, when desirable the quantity of liquid drawn
through may be regulated by this cock. The air drawn into the bottle by the
liquid contained therein being sucked out can only enter the bottle A through the
openings of the vessel E filled with antiseptic wool, as the small plate F always
automatically closes after the sterilisation, and thus germs, and dust are excluded,
so that whilst the bottle is in use no impure air can come in contact with the
food.
"
The advantages of my improved feeding bottle consist, in addition to the
thorough sterilisation and maintenance of the latter during the utilization of
the bottle, more particularly in an even, regulatable, quantity of liquid corre-
sponding to the capabilities of the child being always drawn out, whilst in the
apparatus hitherto employed where the supply of air was defective when the child
was sucking at the bottle owing to a vacuum being formed, the sucking could only
be done with considerable exertion, or when the suction ceased and the vacuum in
the bottle was filled, the liquid was expelled in too great quantities when the bottle
was again used, so much so that it was frequently ejected through the month and
nose of the child. The deleterious offects of these defective feeding bottles,
more particularly in the case of weakly children, as well as of the use of
imperfectly sterilised liquid, need not be further enlarged upon here, as every
physician is thoroughly acquainted with them.
An economic advantage is also obtained by the fact that any milk remaining in
the feeding bottle may, by closing the cock c, be kept sterilised and may be again
used without danger, after being simply warmed.
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 !
claim is :-
:-
"
1. An improved feeding bottle for infants having for its object to be able to
thoroughly sterilise and maintain sterilised the liquid or food in the bottle itself,
consisting in arranging in an ordinary baby's feeding bottle a stopper (B) of
india-rubber, cork, or the like having a tube (C) reaching almost to the bottom of
the bottle, and provided with a cock (c), and also an air supply pipe, (D) with a
valve (F) for letting off the steam and a closing ball (f), the cock (c): being closed
during the sterilising of the food contained in the bottle, and the steam produced
by this boiling or sterilising escaping by the opening of the steam release valve (F)
substantially as described and shown.
2. In a feeding bottle such as described in Claim 1 the opening of the cock (c)
to suit the amount of liquid desired to be drawn through it, and the automatic
closing of the valve F after the boiling is ended and whilst the bottle is in use,
thus freeing the lower opening of the vessel E filled with antiseptic substance
through which air is drawn free from germe, substantially as hereinbefore described
and sliown.
