FLOW CHANNELS FOR A POUCH

摘要

A pouch includes first and second pouch walls that define an interior of the pouch, and an opening to the interior of the pouch is provided in at least one of the first and second pouch walls. A flow channel profile is disposed on an inner surface of the first pouch wall, and a complementary groove is disposed on an inner surface of the second pouch wall. The complementary groove releasably engages the flow channel profile so as to define a flow channel between the first and second pouch walls. The flow channel profile extends between the opening and a portion of an interior of the pouch that is spaced from the opening. When the flow channel profile is releasably engaged with the complementary groove, a tip of the flow channel profile contacts a surface the complementary groove, and a surface of the flow channel profile that is adjacent to the tip also contacts a surface of the complementary groove.
