1 Claim. (Cl. 215--21)
a wine bottle having the device incorporated in
of, which prevents refilling thereof, and which,
the neck thereof.V
at the same time, may be formed without en
larging or changing the size and appearance of a
bottle; or which, wh-en used with relatively small
or short bottles, does not appreciably change the
size and appearance thereof.
The invention is a combination of sleeves and
10; ball checked valves in the neck of a bottle, through
which a fluid may be poured from the bottle, and
which, when an attempt is made to pour or force
the fluid back into the bottle, forms a check valve.
Attempts have been made to provide nonre
ñllable bottles, but substantially all of these re
quire enlarging the size of the bottle, or iiuids
may be forced into the bottle or will even flow
into the bottle when the bottle is immersed in
the fluid.
The object of the invention is, therefore, to
provide means for forming the neck of a bottle,
which permits a fluid to be' readily poured from
the bottle, but prevents its being reñlled without
adding to the height or size of the bottle neck.
Another object is to provide means for prevent
ing refilling of a bottle, in which all of the parts
may be made of glass, or the same material as
the bottle.
Another object is to provide means for pre
3,0, venting refilling of a bottle without the use of
springs or the like.
Another object is to provide means preventing
reñlling of a bottle, in which all the parts remain
stationary on the bottle after being installed.
Another object is to provide means for prevent
ing refilling of a bottle. in which any of the parts
cannot be removed without breaking the bottle.
A further object is to provide means for pre-y
venting reñlling of a bottle, in which the internal
40 area of the bottle is not appreciably reduced.
And a still further object is to provide means
for preventing refilling of a bottle, which may be
incorporated in the normal neck thereof, which
is of a simple and economical construction.
Figure 1 is a view showing a side elevation of
The purpose of this invention is to provide a
double neck bottle with means in the neck there
With these ends in view the invention embodies
an internal sleeve adapted to be ñtted into the
base of the neck of a bottle, another sleeve having
a ball forming a check valve therein, and open
ings in the sides thereof, an outer sleeve forming
a cover for the internal parts and also the neck
of the bottle, and a ball adapted to be placed on
the inside of the bottle.
Other features and advantages of the invention
will appear from the following description taken
connection with the drawing, wherein;
Figure 2 is a yvertical cross-section through the
neck of the bottle..
Figure 3 is a plan view looking downward upon
the upper end'of the device.
Figure 4 isl a sectional plan through the lower
part of the device, showing means locking the
device on the bottle.

In the drawing the device is shown as it masr
be made, wherein numeral! indicates a bottle,
numeral 2 the neck of the bottle forming an outer
sleeve or cover, numeral 3 the upper internal 20
sleeve, and numeral 4 the lower internal sleeve
or bushing.
Y The bottle shown in the drawing is of the
type normally used for wine, and the like, how
ever, it will be understood that this device may 25
berincorporated in bottles of any type or design,
or in bottles used for any purpose, and the neck
and internalÍ parts thereof may be made longer
or shorter, or thicker or thinner,'to accommo
date substantially any type of bottle, and the
device may be provided.v for use with a bottle
having the normal screw cap, as shown in Figure
1, or with a cork, as shown in Figure 2, or any
closing means may be used in combination with
this device.
The bottle is preferably provided with
relatively short, threaded neck 5, having tri
angularly shaped recesses 6 formed in the
threads, and round pins or rollers 1 are placed
in these recesses, and it will be noted that these 40
rollers, installed in this manner, permit the cap
2 to be screwed on the threaded neck 5, how
ever, the rollers ’l instantly move against the
beveled surfaces of the recesses and bind, and,
therefore, positively prevent turning the cap or 45
neck in the opposite direction, so that, once
the neck is in place, it will be absolutely impossi
ble to remove it without breaking the neck or
The neck 5 is shown with relatively rounded 50
threads 8, and the cap 2 is correspondingly
threaded, however, it will be understood that
threads of any type or design may be used. The
bushing 4 is placed in the neck 5, and this bush
ing is formed with an upper valve seat 9, and 55
a lower valve seat I0, with a communicating pas
sage Il extending therethrough, and with a re
cess I2 at the upper end adapted to receive the
sleeve 3 which is freely mounted therein, and
it will be noted that normally a ball I3 will
rest upon the valve seat 9, forming a valve to
prevent a fluid being poured into the bottle
from the upper end, and when the bottle is in
verted, a ball I4, indicated by the dotted lines in
recesses in the threaded surfaces thereof. A cork
cap or closure may then be applied, and the device
is sealed and ready for use.
This bottle will have the appearance of a nor
mal bottle, and the size may or may not be in
creased, and liquor may be poured from the
bottle in the usual manner, however, when an
attempt is made to reñll the bottle the liquor
will be prevented from ñowing back through

weight of the ball being suiiicient to compensate
for the normal pressure of fluid in an open con
tainer, in which the bottle may be immersed.
The ball I4 normally rests in the bottom of
the bottle, and, when pouring a fluid from the
bottle, it may roll down the side thereof, and
against the surface I5 at the bottom of the neck,
so that it will not prevent pouring liquid from
20 the bottle unless the bottle is inverted to sub
stantially a vertical position. ì
The sleeve 3, which rests freely in the recess
I2 of the bushing 4, is formed with openings I6
in the sides, and the upper end I'I is closed.
25 This sleeve is held in place by projections I8
extending internally from the cap 2, and above
the projections is a cylindrical part I9, into
which a cord 20 may be inserted, however, it will
also be understood that this section of the cap
30 may be threaded so that a closure may be
screwed thereon, as indicated by the numeral 2|
shown in Figure 1. This part may be also shaped
to accommodate a closure of any type or design.
It will be understood that other changes may
be made without departing from the spirit of the
invention. One of said changes may be in the
use of other means for securing any of the parts
together, another may be in the use of other
means for holding the balls forming the check
40 valves, and still another may be in the use of
other means for permanently locking the cap or
The upper end of the sleeve is sealed by a cork or 15
cap, or any other sealing means may be used.
The interior sleeves in combination with the
outer sleeves provide a double neck bottle.
Having thus fully described the invention, what
I claim as new, and desire to secure by Letters 20
Patent, is:
A double neck bottle of the nonreñllable type,
comprising a bottle, a boss threaded on the outer
surface extending from the open end of the
bottle, a bushing extending through said boss 25

one of said valve seats positioned on the interior
of said bottle, a valve closing member positioned 30
on the interior of said bottle and adapted to rest
upon the valve seat exposed to the interior of
said bottle, said valve member having sufficient
weight to preventva fluid passing up through
said valve seat with the bottle in the inverted 35
position, a cage with openings in the sides there
