is effectively unlocked to facilitate its removal. The closure skirt likewise has a pair of circumferentially extending snap beads on its inner wall with the midpoint diametrically opposite the lug for snap locking engagement with the annular locking rib. The locking lug lies in the same plane as the locking beads to likewise snap fit beneath the locking rib when the cap is manually pressed down over the container neck.
The closure skirt has an outer finger tab in alignment with the locking lug to provide a bearing surface for the operator's thumb or finger in lifting off the closure when the thumb tab and locking lug are oriented into alignment with the notch in the annular locking rib. Indicia which may be in the form of a trianglefinger dexterity or strength problems because of the necessary force required particularly for the removal of small-sized snap-on closures from small-sized containers Because of their smaller size, such closures resist flexing to a greater extent compared to larger-sized closures, hence requiring a greater force to remove from its container.
Also, during closure removal, the locking lug impacts against the outer peripheral edge of the neck finish, despite the unobstructive passage of the locking lug through the notch in the annular locking rib. Since the locking lug is located at a spaced axial distance from the closure end wall, in the same plane as the snap beads so as to underlie the locking rib in the snapped-on position, the lug strikes the upper peripheral edge of the neck finish at
