ABSTRACT:
A closure device includes a spring member to increase the sealing action of the closure device. The closure device is particularly suitable for use with flexible containers. The closure device includes a male and a female closure element that include male and female hook portions, respectively. The male and female hook portions interlockingly engage with one another to provide a leak proof seal for the flexible container. The spring member is attached to one of the closure elements and acts upon the hook portions of the other closure element to increase the sealing action of the closure device.
