Patent attributes
The present disclosure relates a leakproof or leak-resistant zipper with profiles which include an inter-engaging element with inter-engaging fingers and a leakproof or leak-resistant structure. The slider, when moved in the closing direction, urges the fingers of one profile to inter-engage with the fingers of the other profile and further urges the elements of the leakproof or leak-resistant structure into engagement with each other. The slider, when moved in the opening direction, separates the inter-engaging fingers of the inter-engaging elements and further allows the elements of the leakproof or leak-resistant structure to separate.
