Embodiment Construction

[0063] The invention will now be further elucidated by means of examples and with reference to the accompanying drawings.

[0064] exist figure 1 , discloses a cross-sectional view of a prior art coil type slide fastener 10, wherein waterproof layers 22a and 22b are formed on one side of a pair of cloth tapes 24a and 24b, and coil type coupling elements 20a and 20b are mounted on a To the other side of the tapes 24a and 24b.

[0065] Each of the helical coupling elements 20a and 20b is formed by winding a synthetic resin monofilament. Each of the coupling elements is composed of a joint portion that engages with an opposing coupling element, an upper leg portion, a lower leg portion, and a turnover portion. The helical coupling elements 20a and 20b are sewn to the tapes 24a and 24b by sewing threads, or are knitted or woven to the tapes 24a and 24b when the tapes 24a and 24b are knitted or woven.

[0066] exist figure 1 , the coupling elements 20a and 20b are engaged with ...

Abstract

A waterproof slide fastener is provided. A pair of tapes has coupling elements attached thereto. A coating of polymeric material is provided on at least one surface of the tape and extends continuously therealong. The coating includes in cross-section a fin with a bulbous region. The coating is not extendable beyond the coupling elements when the slide fastener is in an open arrangement.

Description

[0001] The disclosure of UK Patent Application No. 1012592.0, filed 27 July 2010, including specification, drawings and claims, is hereby incorporated by reference in its entirety. technical field [0002] The present invention relates to zippers, and more particularly, the present invention relates to spiral zippers and pertains to waterproof or fluid tight spiral zippers. Background technique [0003] There are many types of fluid-tight zippers in which an elongated strip of cloth supports a continuous row of coupling elements on one side along two edges and a sealing member on the opposite side, thereby creating a waterproof or fluid-tight fastening mechanism. [0004] When the fastening or coupling element consists of a continuous spiral, the coupling element is most commonly knitted or braided onto the elongated tape, or alternatively sewn to the tape surface at the edges of the tape. [0005] There is a continuing need for a zipper that is waterproof and fluid-tight an...
