Abstract
A fitment and cap therefor are integrally molded with lugs interconnecting the part. The fitment has a flange to be attached to a container and an internally threaded spout. The cap has an externally threaded skirt. The lugs are diametrically spaced and interconnect the bottom edge of the skirt and upper edge of the spout. After molding, force is applied to break the lugs and snap the skirt inside the spout, the threads slipping past each other and inter-engaging. A temper-evident band extends around the skirt and is connected thereto by frangible bridges. At diametrically spaced locations vertically projecting fingers extend down from the tamper evident band and are received in sockets on the fitment flange shaped so that the band fingers prevent unscrewing the cap without removing the tamper-evident band. A pull tab and thumb tab assist the consumer in removing the tamper evident band so that the cap may be unscrewed from the fitment.
