CAN-MOUNTED rum nsvrcn FIELD OF INVENTION The present invention relates to pump device for can containers for lubricants and the like, the more particularly to a pumping device including an opening means operable to be mounted in a can container.

DESCRIPTION OF THE PRIOR ART Oil and other lubricants are usually packaged in can containers. Lubrication pump dispensing devices formerly known in the art are generally provided with a container integral therewith or which are mounted on pump device.

Accordingly, it is an object of the present invention to provide a pump device operable to be mounted on the can container in which lubrication materials are shipped.

Another object of the present invention is to provide container-opening means in combination with a pump device operable to cut an opening into a container which will receive the pump device.

These and other objects shall become apparent from the description following, it being understood that modifications may be made without afiecting the teachings of the invention here set out.

BRIEF DESCRIPTION OF THE DRAWINGS:

FIG. 1 is a front elevational view of the can-mounted pump device of the present invention.

FIG. 2 is a side elevational cross-sectional view of the pump device of the present invention taken substantially along the lines 22 of the FIG. 1, and showing the pump device mounted in a can container shown in dotted lines for illustrative purposes.

FIG. 3 is a side elevational view of the pump device showing the cutter means oriented to a can container shown in dotted lines for illustrative purposes wherein the cutter device is oriented to cut a hole into the can container, the hole being operable to receive the pump device of the present invention.

A more thorough and comprehensive understanding may be had from the detailed description of the preferred embodiment when read in connection with the drawings forming a part of this specification.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT Referring now to the drawings and more particularly to the FIG. 1, the can-mounted pump device of the present invention is generally identified by the numeral 10. The pump includes a body portion 11 having a spout 12, a can container cutting portion 13, a handle 14 and a pump housing 15 threadably mounted to the body portion 11. The cross section of FIG. 2 advantageously shows the pump portion of the pump 10. The housing 15 is substanu'ally a cylinder issuing inwardly with respect to the center of the housing to a tubelike orifice entranceway 16 having a flexible tube 17 mounted thereon. The housing 15 is provided with a cylinder 18 having one of its terminal ends suitably fastened to the body 1 1 contiguous with one of the terminal ends of the spout 12 and its opposite terminal end issuing inwardly with respect to the center thereof. A ball 19 is provided in the cylinder to provide a closure. A retaining spring 20 is disposed between the spout 12 and the ball 19 in the cylinder 18. A pump cylinder 21 similar to the cylinder 18 and slightly larger than the cylinder 18 is slidably carried on the cylinder 18 by a pump-operating rod 22 mounted at one of its terminal ends on a wall of the cylinder 21 by a pair of outwardly projecting brackets 23, and carried at its opposite terminal end by a pump handle 24 pivotally carried by the handle 14 of the pump 10. The rod 22 is provided with a spring 25 disposed between the brackets 23 and wall of the housing 15. The pump cylinder 21 is provided with a spring 26 and a ball 27. The ball 27 forms a closure in the cylinder 21. The spring 26 is disposed between the cylinder 18 and the ball 27 in the cylinder 21. When the pump handle 24 is pivotally operated upwardly and downwardly with respect to the handle 14 the cylinder 21, carried by the rod 22 tends to draw liquid in a can container into housing 15. A ball 28 is provided in the housing 15 operable to form a closure with inwardly issuing walls of the housing 15 and the tubelike orifice entranceway 16. When the cylinder 21 is moved downwardly in response to movement of the pump handle 24 the ball 27 is urged upwardly by the liquid in the housing 15, and the liquid is caused to flow into the cylinder 21. Similarly, liquid in the cylinder 21 causes the ball 19 to be urged upwardly to permit the flow of liquid into the cylinder 18 and consequently into the spout 12. Repeated movement of the pump handle 24 causes liquid to be pumped out of the container, through the respective cylinders 18 and 21 and out the spout 12 under pressure. The outermost walls of the housing 15 are provided with threads operable to threadably engage one of the walls of a container as hereinafter described.

The can container cutting portion 13 on the pump 10 includes a cutting edge 29 projecting outwardly from the outermost peripheral edge of the cutting portion 13 and a centrally disposed center punch 30. It has been found in practice that a multiplicity of upstanding cutting means may be suitably fastened to the sidewalls of the housing 15. The cutting means may extend distally below the enu'anceway 16. By causing the upstanding cutting means to impinge a wall of a can container and rotating the body portion 11, threads on the body 11 may engage the terminal edge of the hole in the wall of the can container.

In operation the embodiment of the cutting portion 13 as shown is positioned on a wall of can container substantially as shown in FIG. 3. A sharp blow on the pump 10 causing the cutting portion 13 to impinge the can container and the punch 30 and the cutting edge 29 to pierce the can container. By rotating the pump 10 and the cutting portion 13 a round hole may be cut into the can container. The cutting edge 29 tends to cause the cut edge of the can container to be bent downwardly. That is to say the punch 30 tends to hold the apparatus 10 in position on the can container wall as the cutting edge 29 slices the container wall in response to rotation of the pump 10. The can container wall being cut tends to be bent downwardly forming a depending lip along the terminal edge cut, thereby providing an increased area or thickness about the edge cut. The increased thickness of the terminal edge of the hold readily engages the threads of the housing 15 to securely fasten the pump 10 in the can container. A gasket 32 may be disposed on the housing 15 between said housing and the wall of the can container to seal the housing in the container.

Having thus described in detail a preferred apparatus which embodies the concepts and principles of the invention and which accomplishes the various objects, purposes and aims thereof, it is to be appreciated and will be apparent to those skilled in the art, that many physical changes could be made in the apparatus without altering the invention concepts and principles embodied therein. Hence, it is intended that the scope of the invention be limited only to the extent indicated in the appended claims.
