Improvements in Suckling Bottles.
I, CARL ERNST STOMMEL of Elberfeld, Rhenish Prussia, Germany, Merchant
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 :-
This invention relates to such improvements in suckling bottles for nursing babies
by means of which the sucking piece or nipple can be so fitted into the bottle that
it is pliable and that it can be conveniently fixed therein and taken out for cleaning
and that the milk can be boiled in the bottle and kept hermetically closed so that
it will not get sour or coagulate.
The new suckling bottle is shown on the accompanying drawing in which
Figure 1 shows a vertical section of the same in one manner of construction;
Figure 2 shows a variation of joining the nipple ;
Figure 3 is a plan of Fig. 2.
Figures 4-8 are modifications of the nipple joint.
Figures 9-11 show the arrangement for closing the bottle when used for boiling
and storing milk therein.
In the drawing similar parts are marked by similar letters.
A is the bottle; at its head I insert into it. the hollow conical piece B, that rests
on the top edge by a flange C; the bottom of this conical piece is bored through
centrally so as to allow the lower part of the sucking pipe D to pass through; this
pipe is provided with a ball E by which it is held suspended on the cone B; the
upper part D of the pipe D opens conically to receive the upper part or nipple
piece F of the sucking pipe. This pipe is passed through the central hole in the
cover or lid G, which is screwed or otherwise fixed upon the head of the bottle,
pressing at the same time the flange C of the cone B tight upon the edge of the
bottle lead. Inside of the lid G the nipple pipe F is provided with two balls H
and K; the upper one I bearing against the inside of the lid G, the lower one K
quite at the end of the pipe fitting into the conical opening of the sucking
pipe D.
By this means a ball joint is made between the two pipes D and F allowing each
part to move freely and giving a tight joint in any position of the nipple part and
of the lower part.
At the upper end the nipple pipe F may be provided with a
mouth piece L of india rubber.
In the variation shown by Figures 2 and 3 the conical piece B is replaced by two
india rubber lips or washers M and M', having central holes. The upper one is
stuck upon the upper nipple pipe F and held thereon between the two balls H
and K the lower one is stuck on the lower pipe D which rests on it by the
half spherical opening D2 at its top; this half spherical part being in place of the
conical widening D' of the pipe D in the first case. The two washers with the pipes
therein are now stuck together as shown by Fig. 2; the lid G' put over the upper
pipe and secured to the neck of the bottle, nipping the washers between itself and
the upper edge of the bottle head; thus securing a tight closing and fitting of the
sucking pipe in the bottle.
Now in order to allow a little air to enter into the bottle, as otherwise it would
be impossible to draw milk out of it, I cut a little groove N into the neck of the
bottle as seen by Figures 2 and 3.
Figure 4 shows a simplified construction of the preceding one.
Here the upper
washer M is dispensed with, only one, M³, being used; the lid G' instead of being
made of sheet metal is made of india rubber, which allows in itself the movement

page_text: required for the nipple pipe, as will be easily understood from a glance at Figure 4.
The two pipes and Dare provided with the ball joint as before.
The arrangement of Figures 5, 6, 7 and 8 is identical with the design of Figure 2
so far as the joining of the nipple pipes F D' by means of the two india rubber
washers M' is concerned, but it differs in the manner of securing the lid on the
bottle. In this case the lid Gis held on the head of the bottle by means of a
bayonet joint. At two diametrically opposite sides of the head of the bottle,
grooves are cut vertically into the same and the lid itself is provided with
corresponding projections P as is well known for such joints. At one of the
grooves a recess R is cut into the upper edge of the bottle, so as to create an air
passage and to make the sucking possible.
Now when the bottle is to be used for boiling milk and keeping it in a preserved
state, air must be prevented from entering into the bottle after boiling and the
bottle must be hermetically closed, while the milk is still boiling, so that the nir
and fermenting matters driven out in consequence of the boiling process and of the
heat, can not re-enter again. In that case I take out the pipes and the holding
washers and in their place I put a plnin india rubber washer S, on the top of the
bottle, having a little projection R' fitting into the recess R of the bottle edge and
I use the lid G' to press the washer S on the bottle edge and hold it centrally
thereto.
A pin T on the washer S serves as a handle to hold the washer S in putting
it on and taking it off.
The washer S of course has also grooves O' cut in its sides for the projections P
of the lid to pass through.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed declare that what.
claim is:
1. In a suckling bottle for babies a nipple pipe Fending in two ball pieces 1, K
and a sucking pipe D ending in a conical top D', which two pieces are joined
together and by the ball and come joint are made pliable; a conical holding piece B
and a lid G holding the piece B and the two pipes together as shown by Figure 1|
and for the purpose described.
2. In a suckling bottle for babies the variation in joining the two pipes FD
by a true spherical joint K D and holding them together by two india rubber
washers M M in combination with an air inlet groove N as shown by Figures 2
and 3 and as described.
3. In a suckling bottle for babies the combination of the sucking pipes F D
and an india rubber washer M' with an india rubber lid Gas shown and for the
purpose specified Fig. 4.
4. In a suckling bottle for babies in combination with the pipes F D and india
subber washers M the lid G being joined to the bottle by a bayonet joint, the air
pasange grooves O, R along the side of the head of the bottle and at the top edge
of the same, as shown and for the purpose set forth.
5. In a suckling bottle for babies the hermetically closing washer S with e
projection R fitting into the recess R in combination with the lid G, as shown by
Figures 9 and 10 and for the purpose set forth.
Dated this 16th day of June 1894.
