Combination device with fasteners having rib and groove tracks

Abstract

The object of this invention is to provide a fastening device with adhesive fasteners having rib and groove tracks which closes and seals a bag by alternative engagement of the tracks. In the present invention, to prevent an adhesive agent ( 27 ) from being exposed to impurities or the hands of a user, a predetermined amount of an adhesive agent ( 27 ) is evenly applied only to the groove track ( 23 ), ( 33 ) of each of a pair of fasteners ( 20 ) and ( 30 ) corresponding to each other, so that the groove track ( 23 ), ( 33 ) alternately and reliably engages with an associated rib track ( 25 a ), ( 26 a ), ( 35 a ), ( 35 b ). Therefore, the present invention overcomes the limitation of a material constituting the bag, thus being widely applied to various kinds of products, being convenient in use, achieving a slim structure, and providing an advantage from functional points of view.
