Abstract
A tamper-evident outer cap for a tube spout fitment with push-pull cap for a flexible pouch is provided. The tube spout fitment is sealed to the pouch body, and includes a base portion having a seal-engaging surface disposed within the pouch body and a centrally located passageway. An internal tubular spout projects upwardly from the base portion and has a centrally located passageway. A push-pull cap is slidably retained on the internal tube spout, and is a generally cylindrical member having an outer wall, an inner wall parallel to the outer wall, and an upper wall having a central opening formed therein interconnecting the outer wall to the inner wall. A tamper-evident outer cap is disposed over the push-pull cap, and includes an openable portion, a collar portion permanently retained on the tube spout fitment, and a first connecting member interconnecting the openable portion and the collar portion.
