Problems solved by technology

However, olefin-based zipper systems have their limitations
Most olefin-based zipper systems made from polypropylene and polyethylene are not durable when used in external environments where extreme temperatures affect material properties
Polypropylene and polyethylene zipper profiles lack tensile and tear strength and lack good elongation properties

Embodiment Construction

[0023] Embodiments of improved zipper slider receivers (sometimes referred to as "zipper receivers") and methods of use and manufacture thereof are described herein. In regard to the advantageous aspects of the improved zipper slider receiver, the slider receiver includes a shape that provides an interference fit between the slider of the zipper and the slider receiver. This interference fit provides a seal at the ends of the zipper, making the zipper waterproof. While this is the feature that makes the slider receptacle waterproof, there are many additional features for making the slider receptacle function in a user-friendly and optimal manner. These features include the male side of the zipper extending deeper into the slider receiver than the female side, the slide locking mechanism of the zipper, the materials of the zipper and slider receiver, and the flexible design of the slider receiver.

Abstract

A slider garage includes an overmolded body, the overmolded body oriented on a zipper, the overmolded body including an overmolded male portion and an overmolded female portion, the overmolded male and female portions positioned on an end of the zipper, such that each is on one side of the zipper, the overmolded male portion being shaped such that it fits in the overmolded female portion in a watertight fashion and the overmolded body is molded over a portion of the zipper.

Description

Background technique [0001] The weak point of many zippers intended to be waterproof is at the final closure point of the zipper. In many zipper configurations, there is a small but high-impact aperture at the closure point of the zipper. Depending on the performance required for the waterproofing properties of the zipper, even such a small opening may not be acceptable. [0002] Most if not all polymer zipper systems are made from olefin-based polymers, such as polypropylene or polyethylene. The profile of the polymer zipper is manufactured using the extrusion molding process. Olefin-based systems are common in many polymeric zipper systems due to the inherent low cost of polymeric resins and their low coefficient of friction properties. A low coefficient of friction is important so that the ball and socket of the zipper can be pushed together with minimal effort. However, olefin-based zipper systems have their limitations. Most olefin-based zipper systems made of polypr...
