Claim Text:
1. A clamped type coupling element slide fastener with the structure impervious to fluid, including: a pair of support tapes, symmetrically arranged at the left and right and respectively formed with a first surface and a second surface; two rows of coupling elements, respectively clamped at the inner edge of said first surface and said second surface of said pair of said support tapes, said two rows of said coupling elements being enabled to be mutually coupled or separated, wherein at least one of a top surface and a bottom surface each coupling element of said two rows of said coupling elements being formed with a groove; and an impervious elastomeric member, made of a high polymer elastomer, said impervious elastomeric member being filled in said groove of said two rows of said coupling elements when said two rows of said coupling elements being in a coupled status thereby forming a covering layer, and said impervious elastomeric member being filled in a slit between said two rows of said coupling elements and said pair of said support tapes and in a slit formed on another surface of said two rows of said coupling elements thereby respectively forming a slit filling part and an extending part; said covering layer is cut along a center of said two rows of said coupling elements, said slide fastener being able to be coupled or separated; wherein a top surface of said covering layer of said impervious elastomeric member is not higher than a height of an outer side of said top surface of each said coupling element of said two rows of said coupling elements.
