Abstract:
A flexible container comprising:a pair of flexible panels secured together to form a bag having an open end for access to an interior of the bag, the bag having a first side and an opposite second side; a closure mechanism having elongated interfitting elements each secured to one of the bag panels adjacent the open end of the bag, the closure mechanism extending along the open end of the bag for sealing the open end; a vent member defining an internal passage, the internal passage having first and second ends, the vent member located at the open end of the bag adjacent an end of the closure mechanism such that the first end of the internal passage is in fluid communication with the bag interior, the internal passage providing an exit path for discharge of a pressurized fluid from the bag interior, the vent member located adjacent the first side of the bag; a closure clamp slidingly received by the closure elements for translation of the clamp with respect to the bag between an open bag position in which the clamp is located adjacent the second end of the bag and a closed bag position in which the clamp is located adjacent the first end of the bag; and a flow limiter comprising an end portion of the closure clamp, the end portion of the closure clamp defining a channel adapted for engagement with a portion of the vent member, the flow limiter operably engaging the vent member adjacent the second end of the internal passage such that discharge of the fluid from the internal passage will be prevented in the absence of a predetermined positive pressure in the bag interior, the flow limiter adapted to permit discharge when a positive pressure equal to or exceeding the predetermined pressure is created within the bag interior.
