Abstract
A waterproof zipper with at least one curve includes a first tape and a second tape, and interlocking elements attached to the first tape and the second tape, wherein the first tape and the second tape are curved, and wherein a curve of at least one of the tapes was caused by compaction of that tape. The zipper is coated on at least one side with a fluid impervious coating.
Claims15
A method comprising:
- (A) providing a zipper with a left tape and a right tape each connected to a rail of interlocking elements;
- (B) with the interlocking elements of the left tape interlocked with the interlocking elements of the right tape, putting TPU (thermoplastic polyurethane) between the interlocking elements;
- (C) compacting the left tape and the right tape and forming at least one curve in the zipper;
- and then
- (D) coating one or both sides of the zipper with fluid-impervious coating;
- and then
- (E) scoring the fluid-impervious coating along the rail.

A method comprising:
- (A) providing (a) a first zipper with a first left tape and a first right tape connected to a first rail of first interlocking elements, and (b) a second zipper with a second left tape and a second right tape connected to a second rail of second interlocking elements;
- (B) compacting the first left tape and the first right tape, and compacting the second left tape and the second right tape;
- and then
- (C) forming a third zipper from the left first tape and the right second tape;
- (D) with the interlocking elements of the third zipper interlocked, putting TPU (thermoplastic polyurethane) between the interlocking elements of the third zipper;
- (E) curving the third zipper to form at least one curve in the third zipper;
- and then
- (F) coating one or both sides of the third zipper with fluid-impervious coating;
- and then
- (G) scoring the fluid-impervious coating along the rail of the third zipper.

A method comprising:
- (A) providing (a) a first zipper with a first left tape and a first right tape connected to a first rail of first interlocking elements, and (b) a second zipper with a second left tape and a second right tape connected to a second rail of second interlocking elements;
- (B) with the first interlocking elements of the first zipper interlocked, putting TPU (thermoplastic polyurethane) between the first interlocking elements;
- and with the second interlocking elements of the second zipper interlocked, putting TPU between the second interlocking elements;
- (C) compacting the first left tape and the first right tape, and compacting the second left tape and the second right tape;
- (D) forming a third zipper from the left first tape and the right second tape;
- (E) curving the third zipper formed in (D) to form at least one curve in the third zipper;
- and then
- (F) coating one or both sides of the third zipper with fluid-impervious coating;
- and then
- (G) scoring the fluid-impervious coating along the rail of the third zipper.
