A seal using male and female sides, one having a sealing member bent by the other when joined together

摘要

A closure device that includes a spring member (144) to increase the sealing action is disclosed. The closure device is particularly suitable for use with flexible containers such as plastic bags. The closure device includes a male (150) and a female (130) closure element that include male (152,154) and female hook (140, 142) portions, respectively. The male and female hook portions interlock with one another to provide a leak proof seal for the flexible container. The spring member (144) is attached to one of the closure elements and acts upon the hook portions of the other engaged closure element to increase the sealing action of the closure device.
