A fluid-impervious slide fastener is disposed; an covering abutting member is formed in a central slit of a pair of support tapes, the covering abutting member has a first covering body having a covering layer and a second covering body having a covering layer; when the fluid-impervious slide fastener is in a coupled status, the first covering body and the second covering body are able to elastically abut against each other so as to form a tightening deformation, thus the central slit is provided with a fluid-impervious function against a fluid, for example a liquid, of capable of bearing a hydrostatic pressure of 30 gf/cm.sup.2.

Provided is a container provided with a zipper tape including: a container body including at least a first area and a second area that are opposed to each other; a zipper tape including a first base strip being at least partially bonded to the first area, a second base strip being at least partially bonded to the second area, a first engagement portion and a second engagement portion respectively protruding from the first base strip and the second base strip and being engageable with each other; and a hinge is provided at at least one position that satisfies m/n<0.25, where “n” represents a length of an opening portion of the container body, and “m” represents a distance from the hinge to an inner end portion of the opening portion in a longitudinal direction of the zipper tape.

This fastener tape includes a first belt-shaped member and a second belt-shaped member that are engageable with each other, the first and second belt-shaped members being constituted with a resin composition containing an ethylene-vinyl alcohol copolymer and an acid-modified polyolefin resin.

A manufacturing method of a resin article having a plurality of filamentous projections that are formed in a contact surface of a resin article body may include a thrusting step to thrust acute-angled leading edges of plate-shaped metal parts into the contact surface of the resin article body, a heating step to heat the plate-shaped metal parts before or during the thrusting step, and a pulling out step to pull out the plate-shaped metal parts in a condition in which portions of the resin material of the resin article body is melted around the leading edges of the plate-shaped metal parts and in which melted resin portions are formed on unmelted portions of the resin material of the resin article body.

A piping zipper assembly, a box body and a box body production technology. One side of a zipper and a piping are formed into an integral piping zipper assembly by a coextrusion technology. Then, the piping zipper assembly is directly and accurately installed on the edge of a box shell through the piping, so as to realize the connection of the piping zipper assembly and the box shell. The step is simple, the production efficiency is high, and the production cost can be reduced. Compared with the existing production process in which the piping and the zipper are assembled on the box shell respectively and sewn to the box shell, the present invention greatly saves the installation time and solves the problem of low production efficiency in the existing production process. Meanwhile, the automation of luggage production can be realized.
