Leak proof closure device with spring member

A flexible resealable leak proof container that defines an interior and exterior, the container comprising:

• a thin film defining first and second sidewalls;
• a closure device, the closure device further comprising male and female longitudinally extending closure elements adapted to interlockingly engage one another over a predetermined length, the male closure element includes a base portion and a pair of spaced-apart webs extending therefrom, each male web including and terminating in a respective male hook portion, the male base portion, webs and hook portions being integrally formed in one piece, the male hook portions facing away from one another, the female closure element includes a base portion and a pair of spaced-apart webs extending therefrom, each female web including and terminating in a respective female hook portion, the female base portion, webs and hook portions being integrally formed in one piece, the female hook portions extending toward one another and adapted to engage and mate with the male hook portions when the closure device is fully occluded, thereby defining an interior and exterior of the container, and at least one spring member extending from and being integrally formed in one piece with the base portion of one of the male or female closure elements, the at least one spring member including a free end that acts directly on at least one of the hook portions of the other closure element when the closure device is fully occluded.

A method of manufacturing a closure device, comprising:

• providing a male longitudinally extending closure element, the male closure element including a base portion and a pair of spaced-apart webs extending therefrom, each male web further including and terminating in a respective male hook portion, the male base portion, webs and hook portions being integrally formed in one piece the male hook portions facing away from one another;
• providing a female longitudinally extending closure element adapted to interlockingly engage the male closure element over a predetermined length, the female closure element including a base portion and a pair of spaced-apart webs extending therefrom, each female web further including and terminating in a respective female hook portion, the female base portion, webs and hook portions being integrally formed in one piece, the female hook portions extending toward one another, the female hook portions adapted to engage and mate with the male hook portions when the closure device is fully occluded;
• and
• providing at least one spring member extending from and being integrally formed in one piece with the base portion of at least one of the closure elements, the at least one spring member including a free end that acts directly upon at least one of the hook portions of the other closure element when the closure device is fully occluded.
