Abstract
A sealing device includes an elongated sealing member and a plurality of fasteners spacedly mounted along the sealing member. The sealing member includes a tubular heat sealing layer and a tubular supporting frame, having a flexible ability, coaxially received in the heat sealing layer and defining a deformable channel within the supporting frame. Each of the fasteners has a retention base disposed within the deformable channel and a engagement head outwardly extended from the retention base through the supporting frame and the heat sealing layer in such a manner that the supporting frame and the heat sealing layer are sandwiched between the retention base of each of the fasteners and the engagement head thereof, so as to retain the supporting frame within the heat sealing layer in position.

A sealing device, comprising:
- an elongated sealing member, comprising a tubular heat sealing layer and a tubular supporting frame, having a flexible ability, coaxially received in said heat sealing layer and defining a deformable channel within said supporting frame;
- and
- a plurality of fasteners spacedly mounted along said sealing member, wherein each of said fasteners is made of a stiff metal wire spring having a first end portion bent to form a single spiral retention base, a second end portion bent to form an engagement head, and a curved narrow neck portion between said first end portion and said second end portion, wherein said retention base is disposed within said deformable channel and said engagement head is outwardly extended to an exterior of said sealing member through said supporting frame, wherein said supporting frame and said heat sealing layer are retained at said neck portion of each of said fasteners in position and are sandwiched between said retention base of each of said fasteners and said engagement head thereof so as to retain said supporting frame within said heat sealing layer in position.
