C. HERZOG SELF-CLOSING DISPENSING DEVICE Aug. 29, 1950 Filed Dec. 28, 1948 INVENTOR. CARL HERZOG PJW/ ATTORNEY Patented Aug. 29, 1950 UNITED STATES PATENT OFFICE SELF-CLOSING DISPENSING DEVICE Carl Herzog, Belleville, N. J.

Application December 28, 1948, Serial No. 67,729

7 Claims.

My invention relates to a self-closing dispensing unit.

An important object of the invention is to provide a device of the above mentioned character adapted to be applied to a liquid holding container to permit of the convenient discharge of the contents and the proper cutting off of such discharge to prevent the spilling of the liquid.

A further object of the invention is to provide a dispensing unit adapted to be mounted upon the neck of a container and having parts thereof placed under tension for securely holding the unit in place and other parts placed under compression and serving to close the outlet opening or slit of the device.

A further object of the invention is to provide an internal web which is tensioned to close the slitor slits.

A further object of the invention is to provide a device of the above mentioned character which is of simplified construction and may be readily made integral.

Other objects and advantages of the invention will be apparent during the course of the follow ing description.

In the accompanying drawings, forming a part of this application, and in which like numerals are employed to designate like parts throughout the same:

Figure l is a side elevation of a dispensing unit embodying my invention, showing the same applied to a liquid holding container,

Figure 2 is a front end elevation of the same,

Figure Bis a bottom plan view of the unit,

Figure 4 is a vertical section taken on line 4-4 of Figure 2,

Figure 5 is a vertical section taken on line 5--5 of Figure 4,

Figure 6 is a similar view taken on line 6-6 of Figure 4,

Figure 7 is a horizontal section taken on line 1-1 of Figure 4, and,

Figure 8 is a rear end elevation of the device.

The dispensing device is preferably formed integral and made from resilient material, such as rubber, natural or artificial. The device is preferably made from neoprene, when it is used for handling oil or the like, as this material will not deteriorate upon contact with oil. This device comprises an adaptor including an end I0 having an annular flange I I, increasing in thickness toward its free end for affording an outwardly converging inner wall I2. Formed integral with the end I0 adjacent to its periphery is an axial operating member or arm I3. This member is provided with a pair of spaced longitudinal passages I4 leading into the recess of the flange II and having closed ends I5. The passages I4 are separated by a web I6 extending axially of the operating member I3, as shown. The operating member I3 preferably tapers toward its free end and has an inner cylindrical portion I1, provided upon its bottom with a segmental radial rib or flange I8. The operating member I3 is provided with circumferentially extendingopenings, preferably in the form of slits I9, spaced from the ends I5 and leading into the passages I4. These slits are disposed at a right angle to the longitudinal axis of the web I6. These slits pass through the longitudinal center of the rib I8. The slits are disposed upon opposite sides of the web I6 and preferably extend for less than degrees.

The numeral 20 designates a container for the liquid to be dispensed, such as a metal container for holding oil. This containe'ror can is equipped with the usual screw-threaded neck 2| for receiving the usual can. not shown. The neck 2I is mounted upon the end of the can adjacent to one side thereof, as is customary. The slits I9 are arranged at the bottom, when the adaptor is applied to the neck and the flange ,Il' receives the neck therein, and when the can is horizontally arranged upon its side, for convenient dis- .pensing, Figure 1. Since the device is formed. of rubber it is flexible and resilient and all parts are integral. Due to the taper of the inner face I2, the flange II is distorted when applied .to the 1 neck 2|, Figure l, and its original'cylindrical outer surface is then deformed to taper forwardly. This places the flange of the adaptor under tension, which tends to move the adaptor to-- ward the container 20 for securely holding the dispensing unit upon the neck. This arrangement also exerts forces in opposite directions at the top and bottom of the adaptor which are transmitted to the operating member I3 and serve to place parts thereof under compression which tends to retain the slits I9 closed. The Web It retains the slits I9 closed before the operating member is flexed. When the outer end of the operating member I3 is flexed by being moved upwardly, Figure 1, the slits I9 are opened and the liquid will discharge from the container. This upward movement of the operating member I3 stretches the web I6 longitudinally. When the operating member is released it returns to the normal straight condition and is aided in such returning action by the web I6 which is then under tension. The web I6 therefore pulls the operating member in the direction to close the slits l9. This closing of the slits I9 is also aided by the distortion of the adaptor as applied to the neck of the container.

It is to be understood that the form of my invention herewith shown and described is to be taken as a preferred example of the same, and that various changes in the shape, size, and arrangement of parts ma; be resorted to without departing-field the spirit of my iiiveiitififi "or the scope of the siibjfiind claims.
