ABSTRACT:
A non-resealable dispenser cap construction having an elongate tapered, stepped hollow spout member with an exterior shoulder intermediate its ends, and a discharge orifice. A closure cap member having a transverse closure wall is mounted on the spout member with the transverse wall engaging and closing over the discharge orifice. With the closure cap member so mounted, the transverse closure wall is distorted and biased by its engagement with the wall of the discharge orifice. One of the members is formed with two oppositely-disposed frangible tabs which overlie and are permanently attached to the other member, and each tab has a zone of weakness which can be readily ruptured upon the application of opposing rotative forces to the members. With the cap member removed the orifice is exposed, permitting discharge of the container contents through the spout member. Re-sealing of the cap member on the spout member is prevented, due to a lack of interengageable parts on the two members.
