COMPLETE SPECIFICATION.
Improvements in Sucking-bottles.
EIGEOTER
I, HEINRICH JENSEN of Flensburg, in the Province of Sleswig, German Empire,
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 :-
My invention relates to improvements in sucking-bottles, out of which the fluid,
contained therein, can only How out, when the child sucks at the mouth-piece.
This is arrived at by a ball-valve arranged inside of the sucker.
In order that my invention may be well understood, I refer to the accompanying
drawing, in which similar letters denote similar parts throughout the different
figures, and in which :-
―
Fig. 1 is a longitudinal section of the bottle, showing the valve shut,
Fig. 2 is a similar view showing the valve in an open state, and
Fig. 3 is a section of the valve-box.
The main parts forming the object of my invention are the two valve-box-halves a
and 6 fitting neatly together and having an excavation of a somewhat conical shape,
in which the ball is allowed to play. The suckers being made of an elastic
material is tilted over the complete valve so far, that the open wide part overhangs
enough to be also drawn over the mouth of the bottle. In order to ascertain a good
air-tight fit of the suckers and valve a b, the latter is on the outside provided with
furrows 7. The excavation of the valve being wider on top, ends above and below
into holes o and u forming the seats of the valve. The ball is put in before the two
halves of the valve-box are set together, and is made of any suitable material heavier
than the liquid, preferably of ivory, thus tending always to sink to the bottom, into
the position illustrated by Fig. 1, in which the valve is closed. All parts can be
easily removed to permit a thorough cleaning, which is a very important feature of
my invention.
After cleaning, the parts are put together in the way mentioned above and the
complete sucker is fixed to the bottle, being filled with a nourishing fluid. The
elasticity of the sucker will make it fit to any size bottle.
The bottle is handed to the child in an inclined position the sucker downward.
The ball on account of its greater weight sinks down on the seat u and closes the
valve, thus preventing the liquid from flowing out. As soon as the child starts to
suck, the ball will rise and allow the liquid to come out. This operation will
repeat each time the child swallows and presses the lips together, while starting to
suck. When the baby stops sucking the ball i will also be set at rest and remain
shutting the valve. As may be easily understood the valve will allow liquor to
pass only each time the child sucks and the more so the more violent the sucking is.
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:
In a sucking-bottle: A valve-box consisting of the two parts (a and b), being
provided with an axial conical excavation, in combination with the valve-ball (i),
having a higher specific gravity, than that of the liquid, and the sucker (s) being
made of an elastic material, as for the purpose set forth.
