Leonard, Wake?eld, Nebr.‘ ‘ Application April 17, 1937,‘ Serial No. ‘137,558 2 Claims. This invention relates to dispensing devices and more particularly to an improved type of oil can. 5 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 spout. 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 the purpose of forcibly ejecting the oil from the the bottom II and the side wall of the can or 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, 25 (clam-4s)" 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 invention. 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. 40 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 2 2,127,87/l when the bottom II is ?exed pressure is set up inside the can l0 which can only be relieved by 10 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. described embodiment of this invention without ?exible bottom comprising an elongated spout, a departing from the spirit thereof, such changes and modi?cations being restricted only by the scope of the following claims. threaded closure carried by said spout provided I claim: 1. An oil can comprising a receptacle, a ?exible bottom carried by said receptacle, a threaded neck by said receptacle, a hollow closure 15 carried threada-bly engaging said neck, said closure hav ing vent means therethrough, a spout, a dis charge tube integral with said spout and extend ing through said closure and terminating at a 2. A dispensing means for a receptacle having a with a vent opening, an elongated longitudinally 1O bent discharge tube integral with said spout and adapted to be disposed interior of the receptacle with the inner open end adjacent the bottom thereof, a spherical valve engaging said opening, a resilient arm secured at one end to said closure, 15 and an eye carried by the opposite end of said arm engaging said valve to normally hold said valve in closed position.
