DISPENSING CAP WITH SELE-CLOSING VALVE, HAVING AN AGITATOR INTEGRAL WITH THE MOVABLE VALVE ELEMENT Filed March 19, 1949 Patented July 3, 1951 UNITED STATES DTSPENSING CAP WITH SELF-CLOSING VALVE, HAVING AN AGITATOR INTEGRAL WITH THE MOVABLE VALVE ELEMENT Anthony Sparacio, Brooklyn, N. Y.

Application March 19, 1949, Serial No. 82,435

1 Claim.

This invention relates to a dispensing cap.

It is an object of the present invention to provide a dispensing cap which will be automatically returned to its closed position upon release of the handle serving to open the cap and wherein the means for returning the cap serves to maintain the cap within the container.

It is another object of the present invention to provide an automatic agitating means serving to break up the lumps of powder within the can each time the closure element is operated and also to provide means located at the opening of the closure element to eject the powder to the opening when the dispenser closure is actuated.

Other objects of the present invention are to provide a dispensing container cap which is automatically returned to its closed position, which is of simple construction, inexpensive to manufacture and provide upon the container, has a minimum number of parts, provides a neat exterior appearance, compact, convenient to use and efficient in operation.

For other objects and for a better understanding of the invention, reference may be had to the following detailed description taken in connection with the accompanying drawing, in which Fig. 1 is a perspective view of a container embodying the features of the present invention.

Fig. 2 is a side elevational view of a different type of container utilizing the cap of the present invention.

Fig. 3 is a fragmentary sectional View taken generally on line 33 of Fig. 1.

Fig. 4 is a fragmentary sectional view of the container tilted and the cap moved to an open position to permit the dispensing of the contents of the container.

Referring now to the figures, I represents a container having a top I I on which is fitted a socket l2 for rotatably receiving a semi-spherical shaped cap I3 to the upper end of which is fixed a handle I4 by means of a rivet I5.

Extending through the cap is a transverse sleeve I6 serving as a trunnion for the cap and through which a pin I1 is extended for the securement of the cap to the socket member I2 for pivotal adjustment with respect thereto.

Surrounding the trunnion sleeve I6 is a spring device I8 having a bent and coiled portion I9 and a free end 2 I. The bent portion has a hook extension 22 for engagement with the portion 2| to limit the outward extension of the spring device and a'coil portion 23 surrounding the cap sleeve I6.

When the handle I4 is depressed, the portion 2| will be sprung toward the portion I9 and the portion 2| will tend to spread from the portion I9 upon the handle I4 being released whereby the cap I3 will be automatically moved to its closed position and held by the spring device in tight engagement with the top II of the container.

In Fig. 2 there is shown a slightly modified form of the invention wherein the container has a screw top as indicated at 25. The container has a threaded portion for receiving the top 25. The cap I3 is mounted upon the upper end of the top 25 in the same manner as above described.

It will be apparent that the portion I9 will be in constant engagement with the powder so as to break up any lumps of the powder which may be formed within the container. The hook extension 22 is operable in the closure element and adjacent the portion or socket I2 for use in such a manner as to force the powder out over the edge of the socket.

Accordingly, upon each movement of the closure element is the spring device will be actuated to positively break up the lumps and to positively force the powder out of the opening provided by the socket l2.

While various changes may be made in the detail construction, it shall be understood that such changes shall be within the spirit and scope of the present invention as defined by the appended claim.

Having thus set forth and disclosed the nature of my invention, what is claimed is:

A dispensing cap device for containers comprising a socket member adapted to fit the top of the container, a semi-spherical cap operable in the socket member, handle means on the cap for operating the same, a spring device expandable through the socket and adapted to extend into the container and adapted to be worked by the cap when the cap is moved between open and closed positions, said spring device having an extension extending substantially into the interior of the container to break up the powder as the cap is operated, and a second extension disposed in the opening and forming a part of the spring device to force portions of the contents over the socket member and out of the container automatically as the cap is moved to an open position.
