Description

  The present invention relates to a fastener, and more particularly, to a fastener for fastening a cover portion and a main body of a bag.

  Conventionally, various kinds of fasteners for preventing the cover portion of the bag from opening have been proposed. For example, as shown in FIGS. 8 and 9, a U-shaped gate-shaped fastener 21 is provided on the main body portion 12 of the bag 10, a band 30 is provided on the covering portion 11 of the bag 10, and the covering portion 11 is connected to the main body portion. 12, and a gate-shaped fastener 21 is inserted into the opening 22 a of the base metal fitting 22 attached to the cover 11. And the fastener which stabilizes so that the covering part 11 does not flutter by letting the belt | band | zone 30 provided in the covering part 11 pass through the gate-shaped fastener 21 provided in the main-body part 12 is proposed.

  However, according to such a fastener, there is a problem that in the manufacturing process of the entire bag, an attaching step for attaching the fastener to the bag increases, and as a result, the manufacturing cost of the bag increases. Specifically, when attaching such a metal fitting, the fastener 21 is attached to the main body 12 and a hole is formed in the covering portion 11, and then the base metal fitting 22 is attached by aligning the opening 22 a with the opened hole. Install. Furthermore, the band 30 must be attached to the covering portion 11 in a separate process, increasing the number of manufacturing processes.

  In addition, such a fastener is difficult to close with one hand. That is, it is difficult to pass the belt through the gate-type fastener with one hand. For example, if the band is made thin and easy to pass in order to make it easy to close, the covering portion will come off immediately, and the covering portion will not be stable.

  Fasteners that attempt to solve such problems have also been proposed. For example, there has been proposed a fastener that includes a receiving body that includes a concave portion on the bag body side and incorporates a magnet, and a latching body that includes a convex portion on the covering portion side (see, for example, Patent Document 1). .
