Abstract: 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.

Abstract: A pouch with a valve includes first and second pouch sidewalls sealed to one another to define an opening. A resealable closure mechanism is attached to inner surfaces of the first and second sidewalls proximate the opening to define a pouch interior opposite the opening. A channel extends from the interior to the opening between a section of the first closure element and the first sidewall. A pleated thermoplastic member is sealingly disposed in the channel and has an aperture disposed through the member. A fluid path may provide direct fluid communication between the interior and an exterior of the pouch, wherein the fluid path passes through an edge of the pouch defined by at least one of the first or second pouch sidewalls.

Abstract: A pouch includes first and second opposing pouch walls and a plurality of flow channel protuberances that defines a flow channel between the first and second pouch walls and is disposed on an inner surface of at least one of the first or second pouch walls. At least one of the plurality of protuberances includes a first component extending from the at least one of the first or second pouch walls and a second component extending at a non-zero angle from the first component. The flow channel extends between an opening of the pouch and a portion of an interior of the pouch that is spaced from the opening.
