Patent attributes
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.
