Abstract

A twist open/twist close edge seal closure is described wherein the closure has a sealing disc supported on the interior portion thereof which vertically rises and lowers depending on the rotation of the closure. The sealing disc has a folding finger which compresses against the sealing rib of the container to provide an adequate seal thereof and allows dispensing of the container contents around the exterior portion of the sealing disc upward through a dispensing channel and through the dispensing spout of the edge seal closure. The closure further comprises an anti-crush rib for seating on a container top wall and preventing crushing of the container neck. The container neck preferably includes a quad-lead thread having a pitch wherein a quarter rotation of the closure will open the container and allowing dispensing of the contents therein.
