<p>A seal assembly (20) mountable on a container presents two ports (36, 38) individually and selectively sealed and opened by overlying lids (58, 60). The ports (36, 38) have unobstructed pouring zones, and the lids (58, 60) have coplanar upper surfaces and integral positioning ears (66,68) for resiliently retaining each lid in both an open and a closed position. <IMAGE></p> |
