IMPROVEMENTS IN FEEDING BOTTLES
Year: 1882

Office of the Commissioners of Patents on the 8th June 1882.
GUSTAVE FALCONNIER of Nyon Switzerland " IMPROVEMENTS IN FEEDING
BOTTLES."
My invention relates to certain improvements in feeding bottles and refers.
Firstly To the stoppers and bottles by which the bottle is hermetically closed
when out of use by making a good joint between the stopper and the bottle.
Secondly to a self acting air valve formed by the joint between bottle and
stopper as hereafter described in connection with air passages formed in the bottle
or stopper.
Thirdly By dispensing with the joining between the nipple and Caoutchouc
tube the whole can be taken to pieces cleaned and put together again with great
facility.
The means by which I effect the above are as follows:-
The Bottle is made with inclined grooves going round the top thereof and in
these slides a projection or projections on the stopper which on being turned round
tightens up on the bottle thus hermetically closing it when out of use.
On the top of the bottle is also placed a thin washer of india rubber or other
suitable material which turns upon its edge against the neck of the bottle and
covers up air holes which are made in the bottle or stopper. The air is admitted
to the Bottle when necessary by this valve uncovering the aforesaid holes.
The nipple tubes and guards may be dispensed with and in this case according to
the use to be made of the bottle I fix mouthpieces or nipples of various shapes to
that part of the stopper or cork which is applied to the mouth. In this case the
bottle may be stoppered in any suitable manner. In some cases I weld the inner
glass tube to the stopper to form one with it, the india rubber tube being then
attached to a projection on the stopper
I also form the nipple guards either with a keyhole slot run out to the edge or
with an oval hole so that the suction tube may be compressed therein and may be
easily withdrawn for the purposes of cleansing.

"IMPROVEMENTS IN FEEDING
My invention relates to certain improvements in feeding bottles and refers.
Firstly. To the stoppers and bottles by which the bottle is hermetically closed
when out of use by making a good joint between the stopper and the bottle.
Secondly to a self acting air valve formed by the joint between bottle and
stopper as hereafter described in connection with air passages formed in the bottle
or stopper
Thirdly. By dispensing with the joining between the nipple and Caoutchouc
tube the whole can be taken to pieces cleaned and put together again with great
facility.
The means by which I effect the above are as follows:-
:-
The Bottle is made with inclined grooves going round the top thereof and in
these slides a projection or projections on the stopper which on being turned round
tightens up on the bottle thus hermetically closing it when out of use.
On the top of the bottle is also placed a thin washer of india rubber or other
(suitable material which turns upon its edge against the neck of the bottle and
covers up air holes which are made in the bottle or stopper The air is admitted to
the bottle when necessary by this valve uncovering the aforesaid holes.
The nipple tubes and guards may be dispensed with and in this case according to
the use to be made of the bottle I fix mouthpieces or nipples of various shapes to
that part of the stopper or cork which is applied to the mouth. In this case the
bottle may be stoppered in any suitable manner In some cases I weld the inner
glass tube to the stopper to form one with it the india rubber tube being then
attached to a projection on the stopper
I also form the nipple guards either with a keyhole slot run out to the edge or
with an oval hole so that the suction tube may be compressed therein and may be
easily withdrawn for the purposes of cleansing
And in order to explain my said invention more fully I will now proceed to
describe the same with reference to the accompanying sheet of drawing.
Fig. 1 represents a complete view of the feeding bottle all the accessories being in
position and having a bayonet closing. This feeding bottle is provided with a
dipping tuber a caoutchouc pipe s and a nipple t connected with the latter by
means of shield u as shown at fig 4
The fig 1 shows in dotted lines how the feeding bottle may at will be provided
merely with a nipplet fixed upon the cover of the bottle dispensing with the tube r
the pipes and shield u
In all the other figures the stopper is formed in such manner as to allow to use
it either way
+
Fig 2 represents top plan of the bottle without the stopper
Fig 3 represents the stopper from underneath
Fig 4 a longitudinal section of the nipple showing the disposition of the extremity
of the caoutchouc pipe 8 and the shield u
Figs 5 and 6 plan views of the shield made in two different manners
Fig 7 shows the disposition of the jointing valve A and the air openings B. The
stopper of the flagon is supposed to be provided with a bayonet closing The thin
part of the joint A acts like a valve on the openings B when the sucking takes placed
and prevents the liquid from flowing out through these openings
The left hand part of the fig is a section made in the direction of O Q the right
hand part a section through OP

page_text: Fig 8 represents the bottle similar to that shown at fig 7 as seen from above and
without the stopper
Fig 9 an arrangement similar to that represented in fig 7 only having the joint-
valve A placed at bottom of the stopper together with the air openings B Fig 10
represents the stopper shewn at fig 9 alone as seen from below Figs 11 and 12
show a plan and section of the stopper of the feeding bottle with the joint valve A
and the air openings B the stopper being stuck into the bottle's neck and kept by
means of a screw channel
Fig 13 represents the stopper of a feeding bottle with a bayonet closing
The air openings B are arranged here in a special manner which is more clearly
shown at fig 14 where the stopper alone is represented as seen from below after the
joint valve A has been taken off. The mouth through which the air penetrates into
the apparatus is placed at B (fig 14) whence it circulates through an helicoidal
groove to enter into the bottle near the centre of the stopper at B². The joint
valve A (fig 13) is arranged as formerly and the thin part of the same acts like a
valve upon the opening B2 in such a manner as to permit the air to enter during
the sucking whilst at the same time it prevents the liquid from escaping through
the helicoidal channel
The arrangement of the latter being dispensed with may enable the thin part of
the joint to leave the end B2 of the channel open. In fact the contents of the bottle
would not be in that case liable to be spilled as the air could only penetrate into the
bottle through the nipple which only opens during the sucking and the length of
the helicoidal channel which the liquid must run through would prevent the latter
from issuing at B¹
Fig 15 shows an arrangement quite similar to that of fig 13 only in this case the
helicoidal groove runs through the thickness of the neck of the bottle instead of
running through the thickness of the bottom of the stopper. The stopper is here
merely kept in place through the elasticity of the joint valve A which is likewise
composed of a thick part and a thinner one. For the reasons above stated there
might be placed upon the helicoidal channel a simple India rubber joint leaving
the air opening B¹ and the end B2 of the channel free
The helicoidal groove might of course just as well be bored through the thickness
of the stopper's side instead of running through the side of the bottle's neck It
might also be bored in the thickness of the India rubber A
Fig 16 represents a stopper with a bayonet closing placed within the bottle's neck.
An helicoidal groove similar to that above mentioned with air mouth B' and
opening B2 is bored through the thickness of the stopper. In this case the joint
valve A might likewise be replaced by a single caoutchouc ring leaving the opening B¹
and B² open
The helicoidal groove could also be arranged here in an inverted manner namely
in the bottle's neck instead of running through the thickness of the stopper
Having thus described the nature and object of my said invention and the means
whereby the same may be carried into practical effect I would remark in conclusion
that what I claim as my invention and desire to secure by the hereinbefore in part
recited Letters Patent is
The improvements in feeding bottles substantially as set forth
In Witness whereof I the said Gustave Falconnier have hereunto set my
hand and seal this Second day of December in the year of our Lord one
thousand eight hundred and eighty two
