Abstract
Provided is a waterproof airtight zipper with double zipper sliders, including an upper waterproof zipper part and a lower waterproof zipper part; a lower edge of the first top stopper and an upper edge of the second top stopper are fixedly connected as an integral intermediate sealing structure; the intermediate sealing structure is located between both the zipper sliders of the upper waterproof zipper part and the lower waterproof zipper part and is arranged in a disconnected manner; and an opening is formed at the intermediate sealing structure. A form of double zipper sliders is adopted to make left and right ends stressed at the same time, so that it is more labor-saving to pull open the zipper; the way of pulling open the zipper bidirectionally facilitates operation and use; and the intermediate sealing structure can ensure the air tightness effect of the waterproof sealing zipper.
