COMPLETE SPECIFICATION.
An Improved Infants' Feeding Bottle.
I, WILLIAM MONTAGU COWARD of Islington Terrace, Sydney in the colony of
New South Wales, Engineer, 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 :-
Hitherto infants' feeding bottles have been subject to several disadvantages;
either there is considerable difficulty in keeping the tubes clean and free from
poisonous matter, owing to the incrustation that takes place on the inside of the tube;
or the tube itself soon gets broken while removing it from the bottle, or while it
is being cleaned. It has also been found to be exceedingly difficult for the infant to
draw out the whole of the fluid contained in the bottle; moreover, when the bottle is
laid on its side, the fluid has a tendency to leak out through the stopper at the mouth
of the bottle.
It is with a view to remedy these disadvantages, that I have invented my improved
feeding bottle. To this end, at the lowest part of the bottle near the base, an aperture
is pierced of sufficient size to permit of a free flow of the milk or food from within
the bottle. To this aperture is applied (while the bottle is in process of manufacture)
the end of a glass tube, which, while being fitted, is heated to redness throughout
its length, and in this plastic condition is bent round the external contour of the
bottle until its upper extremity is brought to the same level as the mouth of the
bottle, but on the opposite side of the bottle to that on which is the aperture near
the base. The bottle itself is pear shaped in cross section, and of such form as to
permit of its being wedged between the pillows on which the infant is reclining.
Its peculiar shape, furthermore, lowers the centre of gravity of the bottle, while
full, and tends to keep the aperture at the lowest point. The proper position of the
bottle while the infant is sucking, is, with the small side downwards, so that the fluid
may gravitate towards the aperture pierced in its lowest part. While in this position,
the teat is raised above the level of the food in the bottle, consequently the food
cannot leak out through the teat. Should the bottle be accidentally reversed in its
position, the food within the bottle will be removed from the aperture near the base,.
and will not therefore enter the tube.
In the accompanying sheet of drawings, Fig. 1 is a side elevation of the bottle,
shewing the tube fitted on its external contour. Fig. 2 is a front elevation, also
showing the external tube. Fig. 3 is a cross section on the line A. B of Fig. 1.
Fig. 4 is a plan. Fig. 5 is a glass lengthening tube. Fig. 6 shows the neck of the
bottle in the opposite position to that shown in Fig. 2; and Fig. 7 is a side view
of the teat, which, as may be seen, is inclined at an angle to the axis of the tube, so
as to be more readily available for the infant in any position in which it may be
lying. a is the bottle, 6 the tube, c the aperture near the base, d the neck of the tube,
to which the teat connection is to be made. Figs. 1, 2, & 4 show the tube following
the external contour of the bottle.
By referring to fig. 1, it will be seen that the neck of the bottle and the end of the
tube to which the teat is connected, are inclined to the vertical axis of the bottle at
the same angle, but in opposite directions. When it is desired to remove the bottle
to a greater distance from the child's mouth, glass lengthening pieces, Fig. 5 may be
used, secured to the tube and teat by ordinary india rubber collar attachments. I
prefer to make the teat (see Fig. 7) of such a shape that it shall be slightly inclined
to the axis of the tube or connection to which it is attached, so that it may be turned
in different directions without moving the bottle, and therefore be more readily
accessible, as may be seen by referring to Fig. 1.

page_text: By moulding the tube onto the bottle itself, both the bottle and tube are materially
strengthened, and form a more convenient whole, than when separate, as in ordinary
feeding bottles.
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. A feeding bottle having a suction tube which forms an integral part of the
bottle substantially as described and illustrated in the drawings, and for the purpose
herein set forth.
. 2. A feeding bottle of the shape shown in Figs. 2, 3, and 4 on the sheet of drawings,
bav.ng the exit aperture c near the bottom, and in the contracted portion, so that
while the bottle remains in its proper position, with the contracted portion downwards,
the contents will flow through the aperture, but should the position be changed, the
contents will be removed from the aperture, and leakage will be prevented, sub-
stantially as described.
