<P>PROBLEM TO BE SOLVED: To provide an air exhaust port which automatically and instantaneously opens/closes a valve, prevents air ingress into a vacuum storage bag at a high vacuum state, and is easily fitted to the vacuum storage bag. <P>SOLUTION: The air exhaust port of the vacuum storage bag P comprises a barrel 1 forming an air passage 2 and fitted to the vacuum storage bag P, and a valve element 3 to open/close the air passage 2 of the barrel 1. The barrel 1 is formed by coupling a first barrel 11 having a fixing plate 4 to facilitate fitting to the vacuum storage bag P and a second barrel 12 having a fixing end 5 to fix the valve element 3, and has a pressing part 6 in the center of the air passage 2. A through-hole S is formed in the valve element 3 so as to be located at a central part of the pressing part 6, and the air exhaust port is opened/closed between the pressing part 6 and the through-hole S. A lid body 9 having a pressing unit 8 to press the periphery of the through-hole S of the valve element 3 is freely attachably/detachably fitted to the barrel 1. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
