Self-Sealing Closure System and Method

a self-sealing, closure system technology, applied in the direction of slide fasteners, protective garments, other accessories, etc., can solve the problems of system not providing an effective sealing connection, lack of integrity, and redundancy but not necessarily integrity of the whole, and achieves high flexibility, high flexibility, and convenient operation.

Description

[0001] This invention claims the priority of Provisional Patent Application dated Feb. 11, 2020 by Leonard A Duffy of Hinesburg Vermont entitled “Self-Sealing Closure”BACKGROUND

[0002] There is a need for an innovative self-sealing closure system which is secure, durable, and easy to operate; in particular a closure system which is flexible, non-grabbing, readily cleanable, reusable, and impermeable. Such a system may be used for any application requiring a secure, easy-to-operate impermeable edge closure including but not limited to: PPE Protective Equipment Ensembles as used in chemical, biological, and radiological CBR incidents; spacesuits and vehicle air locks; underwater apparel and equipment; flexible containers; hyperbaric chambers; and diverse consumer and industrial applications including packaging, apparel, footwear, raingear, sports equipment, luggage; and for other general closure and fastening applications which may or may not require a sealed connection.

Embodiment Construction

[0040]As used herein, the terms “top” and “bottom” are intended as relative only in respect to describing the configuration of parts of the invention and have no relationship to gravitational position. Likewise, the term “plane”, as in “common joining plane” is intended to describe only the relative juxtaposition of parts in a static state, in lieu of a continuing geometric abstraction, thus the effective joining plane of the generally elastic and flexible structures may bend or twist relative to common orthogonal orientation. The term “elastomeric” is intended to include a selection or rubber-like materials which are both flexible and resilient with sufficient shape memory to function as designed. The term “containment device” is intended to include a wide range of bags, boxes, luggage, and similar devices.

[0041]As schematically illustrated in FIGS. 1 and 2 the Self-Sealing Closure System includes a first portion 01 for interconnecting with a second portion 02, the portions being e...
