Abstract
A tamper-evident dispensing structure is provided for being sealed to a collapsible pouch. The structure includes a fitment and a lid structure which are each separately molded and which can be subsequently non-releasably attached. The fitment is adapted to be sealed to a periphery of the pouch at an opening in the pouch. The fitment has a receiver and has at least one dispensing flow passage through the fitment. The lid structure includes (1) a base for being fixedly and non-releasably attached to the fitment receiver, (2) a cap for being sealingly and removably mounted on the fitment to occlude the dispensing passage, and (3) at least a first frangible web connecting the cap to the base for accommodating separation of the cap from the base.
