Improvements in Bottles or Flasks.
We, LOUIS JORDAN and STEPHEN WALL18 of 291 Church Street, New York
City, United States of America,, Manufacturers, 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 certain improvements in bottles or flasks.
The object of the invention is to provide improved means whereby liquid can
be drawn from a closed vessel freely and easily, and whereby air is admitted into
the vessel at a point other than the mouth thereof, as the liquid.is:drawn from the
closed flask, bottle or vessel.
These objects aro accomplished by and this invention consists in certain novel
features of construction and in combinations of parts more fully described hereinafter
and particularly pointed out in the claims.
Referring to the accompanying drawings:
Fig. 1, shews in elevation a. bottle provided with my invention.
Fig. 2, is a detail enlarged elevation of the valve.
Fig. 3, is a section through the bottom of the bottle and the valve located
therein.
Fig. J,shews the valve tube of such length and so constructed that it may be
adjusted to vary,size of slits.
Fig. 5, shews the invention applied to a nursing bottle.
Fig.6, shews a different manner of securing the valve.
In the drawings the reference letter a, indicates a nursing or other bottle
or flask having the receiving and discharging mouth or opening b, as usual,
provided with a suitable closure c, such as shewn in Fig. 1, or a nipple as shewn
in Fig. 5.
It is well known how difficult and unpleasant it is to drink or pour liquid from a
bottle or flask when air, cannot pass through the discharge opening into the bottle
as the liquid-passes out.
To avoid this difficulty I provide the bottle with a second opening d, preferably
(although not necessarily) located in the bottom or end of the bottle opposite the
opening b. This opening d, is surrounded with. an outwardly extending neck, as
shewn, and in flasks or other bottles having flat bottoms or bases the bottom is
slightly raised at or about the centre and the neck extends down in the recess
thus. formed so that its lower end will be above or flush with the bottom plane of
the bottle.
In this opening.d, an adjustable (or other) valve e, is located and so arranged as
to admit air into the bottle when anything is drawn from the bottle, but prevent
air or liquid flowing from the bottle except at discharge 6. This valve e, prefer-
ably, consists of a tube, of rubber or other elastic impervious substance closed at
one end and open at the other. The tube near its closed end is provided with one
or more narrow slits or openings i, so formed that inward pressure on the tube will
close said opening or openings air and fluid tight and prevent escape of fluid or
liquid from the bottle, but outward pressure will open the same and allow air to flow
into the bottle. The tube, is inserted open end out into the opening d, and is held
rigidly clamped therein by suitable means, such as a longitudinally perforated or
hollow plug, having the lateral head or flange extending over the end of the
rubber tube and the neck around the bottle opening d, or by having said neck
externally threaded and having a threaded cap open at centre to clamp a flange j³,
of valve as shewn in Fig. 6. The slit or slits i, are, preferably, formed longitudinally
of the tube f, and can be formed' longer than necessary so that the supply of air

and thereby reducing the portions of the slits, capable of opening. The number
or size of the slits can be increased at any time by cutting, and the valve and its
plug can be removed at any time for any reason.
This invention is not limited to the precise valve herein shewn, and the valve is
adapted for use in other bottles than that here shown; and it is also evident that
various changes might be made in the form and arrangements of the parts described
without departing from the spirit and scope of my invention, hence I do not wish
to limit myself to the precise construction herein shewn.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed we declare that what
we claim is :-
:―
1. A bottle or flask having two openings, one of which has an adjustable valve
inserted therein.
2. A bottle or flask having two openings, one of which has a screw or other
closure, and the other separate opening is provided with a valve to admit air and
prevent outflow of air or liquid.
3. A bottle or flask having two separate openings at opposite ends thereof, one of
said openings forming the mouth or discharge opening of the bottle, and a valve
located in the other opening to prevent outflow therethrough and allow inflow of air
into the bottle.
4. A bottle having the usual opening, and provided with a second and
separate opening, and a valve removably located in said second opening to
admit air and prevent outflow of the contents of the bottle through the same
opening.
5. A bottle or flask having the usual opening and a separate and second opening
in its bottom provided with an outwardly extending neck above or flush with the
plane of the bottom of the bottle, and a valve in said opening, substantially as and
for the purposes set forth.
6. A valve consisting of an elastic tube closed at one end and open at the other
end and provided with a slit or opening near the closed end.
7. A valve consisting of an elastic tube closed at one end and open at the other
end and provided with a slit or opening near the closed end, and a perforated plug
in the open end, substantially as and for the purposes set forth.
8. A nursing bottle having the nipple opening and another opposite opening
having the hereindescribed valve as set forth.
