  • Publication number: 20070241023
    Abstract: A dearation valve 1 for a compression bag comprising a main member 2 and a valve element wherein the main member is provided with a mounting plate 21 that comes into contact with the inner surface of a bag sheet B1. A valve mechanism 22 provided in the mounting plate 21 has a valve element support 23 and a deaeration hole 24 is provided in the valve element support 23. The valve element 3 is set by the engagement of a valve element side interlocking part 32 provided in the center of the valve element 3 with a main member side interlocking part 23b provided in the center of the valve element support 23. Since the interlocking parts engage with each other such that the valve element side interlocking part 32 can move in the longitudinal direction in relation to the valve seat side interlocking part 23b, the deaeration hole 24 can be closed off when the valve element 3 contacts the valve element support 23.
