Application July 13, 1933, Serial No. 680,327

1 Claim.

stated in a quick and eificient manner without the likelihood of personal injury.

This and various other important objects and advantages of the invention will become apparent to the reader of the following specification.

In the drawings:-- Figure 1 represents a side elevational view of the container with the cap thereon.

Figure 2 represents a longitudinal view through the container.

Figure 3 represents a fragmentary longitudinal sectional view through the discharge end of the container, with the opening tool inserted therein. Figure 4 represents a cross sectional view taken substantially on line 44 of Figure 1.

Referring to the drawings, wherein like numerals designate like parts, it can be seen that the container is of elongated conical construction. The conical side wall is joined, as at 5, the side wall proper being denoted by the numeral 6. The bottom is denoted by numeral 7 and is soldered or otherwise secured, as at 8, to the lower end of the wall 6. The upper or apex end of the wall 6 is open and when the container and its contents are on sale, this upper open end is closed by a rupturable cap 9 which is suitably secured, preferably by soldering to the apex end of the container, while the top portion of the cap is preferably concaved to facilitate puncturing thereof by the pointed end 10 of the tool 11 which has a hand grip 12 thereon.

l5 sectional The tool 11 is preferably slightly tapered from the handle 12 toward its pointed end 10 so that when the pointed end 10 has pierced the concaved portion of the cap 9 by wedging the tool 11 into the open end of the container, the torn portions of the cap can be pressed snugly against the inner side of the wall 6 so that they will not interfere with the free passage of oil from the container.

In the filling of crank cases, this container is particularly efficient, in that all that is required is to invert the container with the apex end inserted into the filler neck of the crank case. The container may now be left alone until all of the oil has drained from the container. The container can then be removed and thrown away, if desired.

While the foregoing specification sets forth the invention in specific terms, it is to be understood that numerous changes in the shape, size and materials may be resorted to without departing from the spirit and scope of the invention as claimed hereinafter.

Having described the invention, what is claimed as new is:-

A tool for opening containers wherein the container is provided with a neck portion having a rupturable cap; a handle, a shank on the handle for piercing the cap, said shank having a pointed end portion, said shank being gradually tapered toward its pointed end to press the ragged end of the punctured cap against the inner side of the neck after the pointed end portion pierces the cap and as the shank wedges into the neck portion of the container.
