摘要（英）：

Embodiments of a flexible pouch (1) comprise a pouch body (10), a collapsible perforated folded panel (50), an opening seal (60) disposed between the collapsible perforated folded panel and the second ends (18, 19) of the front wall (12) and the rear wall (14), wherein the opening seal adheres the second end of the front wall to the second end of the rear wall which thereby conceals the collapsible perforated folded panel. The release or removal of the opening seal is operable to expose the collapsible perforated folded panel and application of a pull force is operable to outwardly expand the collapsible perforated folded panel to allow draining of liquid or dispensing of dry powder or flakes from the pouch chamber.
