Improvements in Feeding Bottles.
I, FRIEDRICH SCHNEIDER, of Bünde, Westphalia, in the Empire of Germany,
Manufacturer, 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:-
The feeding bottle which constitutes the subject of this invention is represented in
the accompanying drawing.
Figure 1 is a side elevation.
Figure 2 a longitudinal section and
Figure 3 a horizontal section of this improved bottle.
The glass bottle a which is of oval form is open below and hermetically closed by
means of a screw cap c of Britannia metal and a packing ring of cork. Its upper
end is closed and forms an upwardly-bent beak a¹. On one side. the said bottle
possesses a re-entering channel b, which extends from within a short distance from
the metallic cap c, along the entire length of the bottle. Into this channel is inserted
a strong glass tube d which is joined to the wall of the bottle a by melting, and
terminates in the interior of the bottle. The upper part of the aforesaid tube d, is
bent so as to correspond to the curvature of the beak a¹, and is joined to the same by
melting for the purpose of strengthening the bottle. The tube d protrudes however
about three or four centimetres beyond the beak a', and is provided at its upper end
with a small collar d¹ for the reception of a tit.
If deemed expedient the upper end d as far as it is joined to the beak or point of
the bottle by melting can be protected by a metal cap e.
The metal cap e is placed on the bottle in the manner usually adopted by tinmen
in such cases, that is to say, a sheet of metal is cut to the desired form so that when
it is bent round the bottle and tube its edges will meet or overlap as the case may be.
The said edges are then soldered together in the usual way.
On the side of the bottle opposite the channel b is provided a small opening f which
can if necessary, be closed by a metal cap, and which enables the access of air to the
interior of the bottle so that the liquid can flow out.
The advantages of the feeding-bottle as compared with the bottles heretofore used
for the same purpose are as follows:-
1. The bottle can be easily cleaned through the medium of a brush introduced
through the lower opening. In like manner the tube d can be cleaned by means of
a brush introduced either from above or below. Owing to this and to the fact that it
does not possess any angles or corners, an accumulation of miasmata will be completely
precluded even in cases of somewhat superficial cleaning.
The bottles hitherto employed, which are generally very difficult to clean, present
points, especially in the metal fittings, where decomposed alimentary substances can
accumulate, so that these substances, on shaking the bottle become mixed with the
contents of the latter, are taken by the infant and may be the cause of stomach and
bowel catarrhs. There is also a possibility that the warm nutriment, being very liable
to take up foreign substances, will, by contact with the fittings which are for the most
part made of lead, take up particles of lead.
2. When the bottle is placed in a lying position, it will be automatically emptied
through the tube d, if not prevented by sliding the well known tit upon the
latter.
In all existing arrangements of feeding-bottles may be noticed the serious defect
that the sucking of the nutriment is a matter of considerable difficulty for the infants.
As soon as the infant ceases to suck, the nutriment passes back into the bottle, and

page_text: when the nutriment rises again the air contained in the sucking-tube is imbibed with
it, giving rise to flatulence and other similar complaints.
These defects are completely obviated in the improved bottle.
3. The preliminary sucking of the nutriment by the nurse is superfluous in the case
of this feeding bottle, so that the transmission of injurious substances from the nurse
to the infant is precluded.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed I declare that what I
claim is
A feeding bottle in which, when it is placed in a lying position, the outlet of the
liquid will take place automatically through a tube extending along the outside of the
said bottle and terminating in the latter below.
