The ornamental design for a safetyclosure for tops of containers, as shown and described.
FIG. 1 is a side elevational view of a safety closure, the opposite side
being a mirror image thereof, for containers showing my new design, the
container partially shown in broken lines for illustrative purposes only;
FIG. 2 is a top plan view thereof;
FIG. 3 is a front elevational view thereof; and,
FIG. 4 is a rear elevational view thereof.
The bottom does not form any part of the design and, therefore, a bottom
view is not included.
