I claim the ornamental design for a portable male urinal, as shown and described.
FIG. 1 is a perspective view of a portable male urinal of the present invention, showing the portable male urinal having a flexible neck extending between an upper capped input port and a lower collection receptacle with a carry handle;
FIG. 2 is a front elevation view of the portable male urinal of FIG. 1;
FIG. 3 is a rear elevation view of the portable male urinal of FIG. 1;
FIG. 4 is a right side elevation view of the portable male urinal of FIG. 1;
FIG. 5 is a left side elevation view of the portable male urinal of FIG. 1;
FIG. 6 is a top plan view of the portable male urinal of FIG. 1, showing the cap in an open position; and,
FIG. 7 is a bottom view of the portable male urinal of FIG. 1.
The portable male urinal is shown with a symbolic break in its length. The appearance of any portion of the article between the break lines forms no part of the claimed design.
The broken line showing of the upper capped open port, lower collection receptacle and carry handle is included for the purpose of illustrating use and environment and forms no part of the claimed design.
