Abstract
The present invention is concerned with a hair fastener. The hair fastener has a circumferential length from 65-205 mm. The hair fastener is made of an elastic band, a layer of fabric, a first coupler for providing a first connection connecting the opposite ends of said elongate band together, and a second coupler resembling a shell molded over and enveloping the first connection.
Claims18
A hair fastener with a circumferential length from 65-205 mm, comprising:
- a. an elastic band with a width from 0.8-10 mm, defining an outwardly facing surface along a length of said elongate band and with opposite ends defining end surfaces positioned adjacent each other at a connection region thus forming a closed loop;
- b. a layer of fabric enveloping along the length of said elastic band and with opposite ends at the connection region;
- c. a first coupler for providing a first connection connecting the opposite ends of said elongate band together;
- and
- d. a second coupler resembling a shell molded over and enveloping the first connection thus simultaneously i) providing a second connection to the opposite ends of said elongate band, ii) providing protection of said first coupler by enveloping the first coupler, iii) providing connection to the opposite ends of said fabric layer and iv) enveloping the opposite ends of said fabric layer;
- wherein:
- said first coupler connects said opposite ends of the elastic band together by joining at the end surfaces at the connection region but without increasing width or diameter of the connection region;
- and
- said second coupler at the connection region is sized and shaped with an enlarged width or diameter compared to the width or diameter of said first coupler at the connection region, wherein the thickness of the shell of said second coupler is from 1-4 mm.

A method of manufacture of a hair fastener, comprising steps of:
- providing an elongate elastic band with an extended length and with a width from 0.8-10 mm;
- forming a jacket made of a fabric along essentially an entire length over the elastic band;
- cutting the elastic band covered with the jacket into sections, each section with a desired length from 65-205 mm, thus producing a plurality of fabric-covered elastic band sections with opposite ends;
- providing a primary connection by connecting the opposite ends of each elastic band section with a first coupler such that each elastic band section becomes a loop;
- optionally completing formation of the fabric jacket over an entire length the loop;
- and
- providing a second coupler fixedly molded over the connected opposite ends and the first coupler, thus simultaneously providing secondary connection to the opposite ends of the elastic band, protecting the primary connection and connecting of opposite ends of the fabric jacket, the second coupler resembling a shell and with a thickness of 1-4 mm;
- wherein the first coupler is an adhesive for gluing the opposite ends of each said elastic band section together at end surfaces thereof but without increasing circumferential width or diameter of the elastic band section at the opposite ends.
