2 Claims.
This invention relates to dispensing devices
and more particularly to an improved type of oil
An object of this invention is to provide an
improved oil can which is so constructed that
pressure on the ?exible bottom thereof will for
cibly eject oil in desired quantities through the
Another object of this invention is to provide
a valved spout for an oil can which is adapted
to admit air into the can as the oil is forcibly
ejected therefrom.
A further object of this invention is to pro
vide an improved spout for an oil can which
15 may be attached to a conventional oil can for
adapted to engage against the vent 22, being held
thereagainst by means of a spring 26 having an
eye 25 at one end‘ thereof upon which the ball
23 is adapted to seat. The other end of the
spring 24 is provided with one or more loops bu
and the extremity 26 of the spring 24 is soldered
or otherwise fastened to the‘ inner bottom I8
so that the ball 23 will be yieldably supported in
a position to close the vent 22.
An elongated tube 21 is formed integral with 10
the spout I2 and extends through the inner bot
tom I8 and the outer Wall I9 of the plug I5
and is preferably bent longitudinally in a man
ner such that the inner and thereof will be po
sitioned closely adjacent the junction between 15

can as the bottom is ?exed.
receptable I0.
With the foregoing and other objects in view,
the invention will be more fully described here
2 O matter, and will be more particularly pointed out
in the claims appended hereto.
In the drawing, wherein like symbols refer to
like or corresponding parts throughout the
several views,
Figure 1 is a vertical section partly broken
away and in side elevation of an oil can con
structed according to an embodiment of this
Figure 2 is a bottom plan of the closure of
30 the discharge tube in section.
Referring to the drawing, the numeral Ill des
ignates generally a liquid receptacle which is
adapted to receive oil or the like. This recep
tacle III is provided with a relatively ?exible bot
3 UT tom II and a reduced threaded neck I3. Prefer
ably, the receptacle I0 tapers upwardly and is
substantially conical in con?guration, although
I do not wish to be limited to the particular con
?guration of the body of the can I0.
In order to provide a means whereby oil or
other liquids may be readily dispensed from the
can I0, I have provided a spout I2 of suitable
length having, in the present instance a curved
outer end portion I4. This spout I2 at its inner
45 end is secured to a chambered plug or closure I5
In the use and operation of this dispensing de
vice, the closure I5 is unthreaded from the neck
I3 and the receptacle II) ?lled with the desired 20
liquid which, in the present instance is oil and the
closure I5 is then replaced. The inner open end
of the discharging tube 21 will be positioned close~
ly adjacent the bottom I I at the periphery there
of so that when the bottom I I is ?exed inwardly 25
to force oil out of the receptacle I0, the move
ment of the bottom I I will not effect the passage
of oil from the receptacle I0 into the inner or
open end of the discharge tube 21.
When the bottom I I ?exes outwardly of the re 30
ceptacle ID a partial vacuum will be formed in the
receptacle III which is relieved by atmospheric
pressure, unseating the valve 23 and permitting
air to pass from the vent 2| through the hollow
plug or closure I5 and then pass the opened valve
23 into the interior of the receptacle III. The
check valve 23 will yieldingly close when the air
pressure inside the can I0 is substantially equal to
the atmospheric pressure. Through the con
struction of a can of this type the ?exing of the 40
bottom Ill will, at all times, discharge oil through
the spout I2 irrespective of the angular position
of the can so long as the inner open end of the
discharge tube 21 is submerged in the oil. Prefer
ably, the curved end portion I4 of the spout I2 is
directed in the same direction as the inclination
I ‘I. The threads l6 are adapted to engage the of the inner portion of the tube 21 so that when
threaded neck I3 of the receptacle I0 so as to oil is being discharged from the receptacle It], the
user of the device will naturally turn the can so
tightly secure the spout I2 on the upper end of
that the curved portion I4 will be downwardly and
50 the receptacle Ill. The chambered plug I5 com
this will then simultaneously position the inner
prises an inner wall I8 and an outer wall I9 pro
vided with an annular raised portion 20 engaging open end of the discharge tube 21 at the bottom
of the liquid so that irrespective of the quantity
about the inner end of the spout 20 which is pro
vided with an air vent 2|. The inner wall I8 is ' of oil in the can I0, oil will at all times be ejected
upon ?exing of the bottom due to the fact that 55
55 provided with a vent 22 and a ball Valve 23 is
provided with peripheral threads I6 and a ?ange
when the bottom II is ?exed pressure is set up
inside the can l0 which can only be relieved by
point adjacent the junction of said bottom and
the ejection of oil through the discharge tube 21
and the spout l2.
It is, of course, understood that various changes
the side wall of the receptacle, a ball valve en
gaging said vent means, and a resilient arm ?xed
at one end to said closure and provided with an
eye at the other end engaging said valve to nor
and modi?cations may be made in the details of
construction and design of the above speci?cally
mally hold said valve in closed position.
