Patented Apr. 26, 1932 UNITED STATES OSCAR WILLUMSEN, F OCEAN PARK, CALIFORNIA AIR VENT FOR DISPENSIZN'G CONTAINERS Application filed February 11, 1930. serau No. 427,351.

Thepresent invention relates to dispensing containers and more particularlyto improve :ments in'reserve dispensing containers such as disclosed in my allowed application Serial Number'300;810 allowed October 21, 1929.

The primary object ofthe present invenation isztoprovide a dispensing container having a detachable nozzle normally concealed within the container, with means for venting the container when the nozzle applied :to the-dischargeopening of the container.

A further object resides in the novel .arrangement-whereby the outer end of the air -venttube is closedby'the closure cap for the discharge opening of the container.

A further object resides in the novel man ner in whichthe vent tube is disposed within the container soastoprev-ent escape ofthe liquid thru'the vent tube while the contents are being dispensed thru the discharge open- -in g of the container.

Astill'further objectresides in the-provision of an rimproved dispensing container for oils, gasoline and the like having a pair 60f concentrically arranged, spaced apart necks at its discharge'end, with a vent tube opening to the atmosphere between the necks for venting the container when the discharge nozzl'eis detachably connected with the inner- 'most' neck.

Other objects andadvantages of the invention will be apparent during the course of the following detailed description, taken in connection with the accompanying drawings *forming a part of this specification and in which drawings r p Fi-gurel is aviewpart inlongitudinal section and-part in side'e levation of the improved container. 1

iii-the drawings, and wherein similar ref- 14 whereby the washer16 of the closurecap -erence characters designate corresponding parts thruout the several views, the reserve dispensing container or receptacle includes a tubular body portion 5 being closed at its forward end by a front endwallfi and 'at its rear or opposite end by a rearend wall1'8. Each end wall 6 and 8 is preferably provided with an annular attaching flange 9 which maybe secured to the ends of the body portion 5 in any preferred manner such as by soldering or the like. Secured intermediate the ends of the body portion 5 is a'suitable handle 10 which extends longitudinally of the body portion.

The rear end wall 8 supports a tubular .65- chamber forming member 11 which projects axially into the body portion 5 and "the chamber formed by the member 11 isadapted to removablyreceive a-spout or nozzle 12 adapted for detachable connection with the dis charge end of the container. The -rneth0d and manner of mountingthis nozzle in'the chamber 11 is clearly set forth in my allowed application above referred to. r The end wall 8 is also adapted to receive the threaded cap '13 serving to retain the nozzle 12 in'thechamber 11.

Theend wall 6 at the forward or discharge end of the container is provided with an axially disposed tubular threaded portion or .30

neck 14 for threaded reception of a closure cap 15. The closure cap 15 is-threadedexteriorly upon the neck 14 and is preferably provided with a sealingwasher 16 for sealing engagement with the outerend edge ofthe n8 neck 14. Secured at its inner end to theend wall 6 inwardly oftheneck 14 is a threaded sleeve or inner neck 18 which is-of less' external diameter than the internal diameter of the neck 14 forming. an annular pocket:19 between the concentrically arranged sleeves. This threaded sleeve 18 is secured'to-thewwall escape of liquid from the container. This threaded sleeve 18 forms the discharge opening ofthe container and preferably has its outer end curled as at-21 and disposed flush with'the outer edge of the threaded portion will seat upon the outer end of each of the necks 14 and 18. The end wall 6 preferably has an outturned flange as at 22 in Figure 1 which extends into the annular pocket 19 to act as a spacer between the sleeve 14 and 18 and further aids in properly connecting the sleeves to the end wall.

The tubular spout or nozzle 12 is preferably of flexible tubing and is provided at its rear end with an enlarged internally threaded head portion 24 which is adapted for threaded connection with the external threads of the inner sleeve 18 after removal of the closure cap from its threaded connection with the outer sleeve 14. The outer or discharge end of the tubular flexible spout 12 is provided with an extrenally threaded discharge cap 25 to which an extension or a reducing nozzle may be connected for discharging the contents of the container into a relatively small opening, when desired.

As will be observed in Figure 3 the spacing between the necks 14 and 18 is greater than the thickness of the spout head 24 so that threading of the head upon the inner neck does not close the annular pocket 19 to the atmosphere.

Referring now to the novel venting means for permitting ready and free escape of the contents thru the nozzle 12, the same embodies a metal air vent tube extended thruout the length of the tubular body portion 5 with one end opening into the tubular body portion and its opposite end opening into the annular pocket 19. This air vent tube 30 has its outer end 31 extending with a sealed connection 32, formed by the solder 20, between the inner connected ends of the spaced necks 14 and 18 so that the tube opens into the annular pocket 19 in alignment longitudinally of the body portion 5 with the handle 10. Fromthe outer open end 31 of the tube 30 the tube extends upwardly along the inner surface of the front end wall 6 as at 34 and is then extended in a straight line along the inner surface of the body portion 5 as at'35 with its open end 36 spaced slightly from the rear end wall 8. The tube portion extends longitudinally of the body portion 5 directly beneath the handle 6 and in longitudinal alignment therewith, and may be secured to the body portion 5 in any preferred manner such as by soldering at the points 37. This extending of the portion 35 along the entire length of the body portion 5 and at the top side of the container when held by the handle 10 for dispensing the contents of the container disposes the open end 36 of the vent tube above the liquid contents of the container so that the liquid is not permitted to escape thru the vent tube while in the act of emptying the container.

In conditioning the container for dispensing the liquid therefrom, the cap 13 may first beremoved andthe nozzle 12 removed from the chamber 11. The container may then be placed on end with the wall 6 uppermost and the closure cap 15 removed so that the nozzle head 24 may be threaded upon the inner sleeve 18 as shown in Figures 2 and 3. The container may then be held by the handle 10 and the nozzle 12 placed at the desired location for delivering the contents of the container. On tilting the container upwardly as shown in Figure 2, air will be drawn thru the annular pocket 19 into the outer end 31 of the vent tube 30 and permits free escape of the liquid thru the discharge spout 12.

When filling the container thru the opening formed by the inner sleeve 18, a quantity of the liquid will enter the small vent tube 35 to the level of the liquid in the body portion 5, and thru handling of the container a small quantity of the liquid may find its way into the annular pocket 19 which is ordinarily closed by the closure cap 15. In standing the container on end for applying the nozzle 12, any liquid in the pocket 19 will drain back int-o the container. When the container is tilted for dispensing the contents, the liquid escaping thru the nozzle 12 will create a suction in the small vent tube for drawing the small column of liquid therein into the body portion 5. The conical portion of the spout head 24 will have a tight fit with the inwardly curled outer end 21 of the tube 18 to prevent escape of the liquid at the joint between the head and sleeve.

Thus it will be seen that a novel arrangement has been disclosed whereby the container may be vented from the discharge end without liability of any of the liquid escaping thru the vent tube. It will also be apparent that a novel arrangement has been shown whereby the single closure cap 15 aside from sealing the discharge opening of the container also serves to close the outer end of the vent tube.

Changes in detail may be made to the form of invention herein shown and described, without departing from the spirit of the invention or the scope of the following claims:
