ABSTRACT:
For tent-type paperboard containers as well as other containers, a spout fitment is attached surrounding a hole in the container. The fitment spout has internal threads and an external flange which seals around the hole and is fixed to the container by thermal means, adhesive or the like. The cap has a top disk from which an externally threaded skirt depends. The exterior of the skirt has gripping ribs to assist in screwing and unscrewing the cap. The lower edge of the skirt seals against a sealing membrane on the spout. Surrounding the skirt is a tamper-evident band attached to the lower edges of the ribs by frangible bridges. The tamper-evident band has locking means engaging complementary locking means on the fitment. Thus, the cap cannot be unscrewed without removing the tamper-evident band. By unique design, the fitment and cap may be molded in one mold cavity.
