We claim the ornamental design for a sport cup, as shown and described.
FIG. 1 is a front perspective view of a portion of a sport cup.
FIG. 2 is a front view of the portion of a sport cup shown in FIG. 1.
FIG. 3 is a right side view of the portion of a sport cup shown in FIG. 1.
FIG. 4 is a left side view of the portion of a sport cup shown in FIG. 1.
FIG. 5 is a top view of the portion of a sport cup shown in FIG. 1; and,
FIG. 6 is a bottom view of the portion of a sport cup shown in FIG. 1.
Any showing of the environment by broken lines having equal length segments shows unclaimed portions of the sport cup only and forms no part of the claimed design. The portions of the sport cup shown in broken lines having unequal length segments illustrate the boundary of the claimed design and form no part of the claimed design. The design shown in FIG. 1 is not visible in the rear view; therefore, the rear view has been omitted.
