2 Claims.
This invention relates to improvements in con
tainers of .the type designed to prevent misrep
resentation regarding the contents and as such
is in the form of a nonure?llable receptacle.
551
In the art to which the present invention re~
lates e?orts have been popularly -made<to pre
vent the re?lling of receptacles, such as bottles,
in order to avoid the possibility of either the oiier
ing of a spurious substitute or the illegal mar
10 keting of a re?lled bottle or other receptacle.
Quite extensive e?orts have, accordingly, been
exerted in the direction of preventing the re?lling
of bottles and like receptacles, and containers
and such receptacles have come to be commonly
is known as non-re?llable bottles even though it is
well known ‘that it is practically impossible to
actually prevent re?lling because of the advance
that has been made in the welding of glass by
which it is possible to either remove the bottom
2.0 of a glass receptacle and re-weld it in a manner
not observable, or it is possible to drill through an
appropriate part of the Wall of the receptacle
and after ?lling weld the opening thus formed in
a not readily detectable manner.
It is, therefore, not sufficient to provide means
to prevent liquid being introduced into a bottle
or other receptacle through the opening from
which liquid is intended to be discharged. Ac
cordingly, the present invention provides the
30 novel combination of means for preventing the
re?lling of a receptacle through the port or open
of the contents of a receptacle and means co
operating therewith ior precluding further dis
charge after an amount has been discharged sub
stantially equal to the capacity of the receptacle. 5
The invention also includes in greaterv detail
in such an arrangement means for preventing
repetition of the measuring operation or restora
tion thereof to a condition enabling such repeti
tion.

The invention also comprises certain other
novel constructions, combinations, and arrange
ments of parts as subsequently speci?ed and
claimed.

In other words, the novel idea of the present
invention is directed to preventing discharge of
49 the contents of a receptacle after the receptacle
has ‘once been emptied rather than, or supple
mental to, the eiiort to prevent re?lling, so that
thepresent invention may be tersely described as

With this and more detailed objects in view as
will in part hereinafter become apparent and in

The invention further comprises a control of
the neck 2. Seated within the neck 2 and clos- 50

charge of liquid from container l and precluding
re?lling of the container through the said neck.
The said stopper consists of a tubular housing

while the pawl presents a rounded portion in the

erator hearing the resulting sound will discon

be rotated in a contra-clockwise direction. Dur

or suiiiciently nearly invert, the bottle or recep
tacle | to enable liquid to ?o-w along the chamber
6 through the slots l2 and I4 and into the dis
ing such rotation, the pawl 22 successively swings
upon its pivot out of one of the grooves 2| against
the pressure of spring 26, rides across the thread
segments, and drops into the next groove 2|, and
so on, as the stem 23 is rotated. The thread 20
10 is of the righthand variety so that, should the
stem ll be revolved clockwise instead of contra
clockwise, the stem would be caused, owing to its
thread engagement with the base or bottom l5
of housing 4, to- move inward or downward; but
15 the presence of the pawl 22 and its action with
respect to the thread segments precludes the pos
sibility of any such movement. Pawl 22, there
fore, permits only such rotation of the stem I‘!
as will cause the stem to travel outward through
20 the bottom |5 of housing 4.
Of course, when the receptacle of bottle I is
?rst ?lled and the housing 4 and its carried parts
are inserted, the stem I‘! will be in its lowermost
position, and the stop 24 is located to contact with
25 the cap 23 in timed relation to the exhaustion of
the contents of the bottle to avoid any appreciable
further movement of the parts after exhaustion
of the contents of the receptacle I. Furthermore,
the stop 24 is located with respect to the threads
30 such that, when the pawl 22 drops into the last
groove 2| which it can engage as the stop 24 con
tacts, the cap 23 and slot l3 will preferably be
out ‘of alinement with the slot ||. Of course, the
grooves 2| are located relative to the location of
35 the slots l3, l4 and I2 such that, when the pawl
22 engages any one of the grooves 2| where the
slots l3 and H are in registration, the next step
bringing the pawl into engagement with the next
groove 2|, causes the shell ID to have such angu
lar advance as to bring the slots | 4 ‘and I2 into
registration, so that the slot | | is closed, and these
successive relationships are maintained by the
successive step-s represented by the succeeding
grooves 2| in their relation to pawl 22 as the stem
45 I1 is revolved.
'
To avoid delay in the rate of discharge from
the discharge tube or shell I0, it is desirable to
provide means for admitting air to the interior
of the shell II! when liquid is to be delivered there
from. For this purpose, a preferably minute port
2‘! is formed through the neck 2 and through
the housing 4, preferably at a point diametrically
opposite from the nozzle 3. The shell It] is pro
vided in line with each of the slots |3 with a
55
series of miniature ports 28 alined vertically and
spaced apart equal to the longitudinal travel of
charge tube |ll until it is ?lled. The operator then
turns the knob IQ for one more click which cuts
off the registration of slots | 4 with slots l2, and
brings a slot l3 into register with the slot II, and
at the same time brings a port 28 into register
with the port 21. The contents of the discharge
tube may thus be freely discharged through the
spout or nozzle 3.
This operation may be re
peated step by step until the entire contents of 615
the bottle has been discharged, and at that time
the stop 24 will either be in contact with the cap
23 or sufficiently near to the cap to preclude any
appreciable introduction or removal of liquid;
It should be understood that should an operator L20
choose at any time he can, when a slot I3 is in
register with a slot | |, pour liquid into the spout
3 sufficient for ?lling the discharge tube I0, and
then by turning the tube Hi to the next notch and
thus bringing the slots I2 and M into register, F25
cause the thus introduced liquid to enter the re
ceptacle I. _Such an introduction of liquid, how?
ever, can not be of any pro?t to the operator,
since he has lost just that much in the longitu
dinal thrust of the tube Ill, which thrust is the
controlling factor in emptying the receptacle.
When the shell or tube II! has reached its maxi
mum limit of longitudinal thrust there is nothing
that can be done to allow the'contained liquid to
escape, if there be any contained liquid. Accord T135
ingly, the length of the stem I‘! is preferably
slightly longer and the number of available
notches over which the pawl 22 may travel slight
ly greater than that required for‘ theactual com~
plete emptying of the receptacle I, so as to in
sure against accidental movement of the operat
ing knob l9 having the eifect of rendering some
of the original contents inaccessible.
After the bottle has once been completely
emptied and the discharge tube or shell ID has
reached the limit of its longitudinal travel from
which it can not be backed off, any ?lling of the
bottle as by the removal of the bottom and the
re-welding of it will be of no avail, since it is not
possible, having once emptied a bottle, to re
empty it. Accordingly, the present invention in ~50
volves not only a non-refillable receptacle in the
sense in which that term is generally accepted,
but also includes the capacity to resist re-empty-'
ing. Thus, re?lling is effectively discouraged.
By these means not only is the public assured 555
the shell Ill incident to a complete rotation or v of the genuineness of the original contents, but ‘
movement thereof through 360°. In other words, the possibility of’ marketing a receptacle bearing
the distance from one port 28 to the next lower a revenue stamp that has once been used is de
stroyed.
60 port 28 of the several rows of ports below the
several slots |3 is equal to the spacing of the
thread helices of thread 20. Thus, when'a slot
|3 comes into register with slot ll, one of the
ports 28 comes into register with port 2'! and al
65 lows su?icient admission of air to permit free dis
charge of the contents of the discharge tube It].
. The operation should be obvious from the fore~
going, but may be brie?y stated, after the parts
have been assembled with the receptacle | ?lled
and the closure l9 resting on the upper end of
housing 4, or substantially so, to consist of turn
ing the closure l9, which thus serves as a knob,
that is in the direction which is contra-clockwise.
The ?rst tiu‘ning movement will result in the
75 pawl 22 rising over one of the thread segments
25
The matter of effectiveness of construction of
course possesses the possibility of some variation,
but in order to insure the best results it is de
sirable wherever there is not an actual glass weld
between two glass portions to provide a fusible
cement between the separate parts that are
brought together and to fuse the cement after the
application. For instance, the housing 4 is pref
erably coated with a fusible cement especially at
its outer end portion, which cement is fused after
the insertion of the housing 4 in the neck 2._ The
relatively tapered contacting faces of the two
parts insures a tight joint in the ?rst place, and
the fused cement precludes possibility ofv separa
tion in addition to the capacity of the washer 1.

20 receptacle I.
What I claim is:
1. The combination with a receptacle having
an intake and a discharge ori?ce, of a valve cas
ing ?xed in said receptacle, a valve rotatable in
said casing and having intake and discharge ports
adapted to be brought alternately into communi
cation with the interior of the receptacle and
with the exterior thereof and located to avoid.

' formed by the intersection of the threads with
said grooves, and a stop at the free end of the‘
stem, to limit the total possible movement of
said valve in the direction permitted by the ac 10
tion of the pawl.
2. The combination with a receptacle having
an intake and a discharge ori?ce, of a cylindrical
valve casing closed at one end and ?xed in said
receptacle, a valve rotatably and slidably mount~ 15
ed'in said casing and having intake and discharge
ports adapted to be moved alternately into com
munication with the interior and exterior of the
receptacle, said casing having its closed end lo
cated within the receptacle and provided with 20
an axial internally screw-threaded aperture, said
valve having a screw-threaded stem engag
ing the threads of said aperture, and a stop at
the free end of the stem to limit the total possi
ble movement of the valve in one direction axially 25
of said casing, said stem being provided with
grooves extending lengthwise thereof,>a pawl piv
oted in said casing, and means ,for holding the
free end of said pawl against the grooved stem
to prevent rotation of the valve in one direction.
