<p>For tent-type paperboard containers as well as other containers, a spout fitment (41) is attached surrounding a hole in the container. The fitment spout (42) has internal threads (44) and an external flange (47) which seals around the hole and is fixed to the container by thermal means, adhesive or the like. The cap has a top (52) from which an externally threaded skirt (59) depends. The exterior of the skirt (54) has gripping ribs (56) to assist in screwing and unscrewing the cap. The lower edge (66) of the skirt (54) seals against a sealing membrane (48) on the spout. Surrounding the skirt (54) is a tamper-evident band (61) attached to the lower edges of the ribs by frangible bridges (62). The tamper-evident band (61) has locking means (63) has locking means on the fitment. Thus, the cap cannot be unscrewed without removing the tamper-evident band (61). By unique design, the fitment and cap may be molded in one mold cavity.</p> |
