ABSTRACT:
A novel flat tubular plastic flutter valve for filling adjacent thin film evelope chambers into which it is peripherally sealed, as for cushioning and protecting items to be shipped within folder-over chambers, and in which the valve is notched to divide from a common external fluid (preferably air) filling inlet into a pair of independent flutter valve outlets one extending into each of the adjacent chambers and diverging from one another along the notch; the flutter valve preferably having low impedance characteristics imparted by a push-in and withdrawable fluid-filling block and stems that enable ready deflation and re-inflation of the chambers. The valve is also useful with other chamber bladder configurations, including undivided single chambers, among others.
