ABSTRACT:
A closure and applicator cap adapted to be attached to the neck of a container which holds a flowable product. The cap includes a molded plastic cap body having a tip portion and an axially-extending discharge passage in the tip portion. The wall of the tip portion has an annular exterior cut extending completely around its circumference. The cut forms an annular zone of weakness in the wall of the tip portion. This zone of weakness is disposed in a first plane which is transverse to the axis of the tip portion, and which is offset downwardly of a second and higher plane containing the uppermost external annular edge of the cut. The tip portion has a flat extremity above the cut to enable it to be grasped and shifted so as to rupture the zone of weakness of the tip portion and expose the discharge passage thereof for the dispensing of product therethrough. Optionally, reinforcing struts are molded integral with the flattened extremity of the tip portion, to increase strength against inadvertent breakage.
