BAG BUNDLE, BAG OPENING DEVICE, BAG HOLDING STRUCTURE FOR SAID BAG OPENING DEVICE, AND BAG AND BAG BUNDLE HELD BY SAID BAG HOLDING STRUCTURE FOR BAG OPENING DEVICE

摘要

This bag bundle has a plurality of bags that house objects, layered therein. The bags comprise: a sheet-shaped first bag piece; a sheet-shaped second bag piece that, together with the first bag piece, constitutes a bag structure; an extension piece extending further upwards from an upper end, in the height direction, of the second bag piece; and an engagement hole formed in the extension piece and capable of engaging with an external member. The bag bundle having a plurality of said bags layered therein has a joining section that joins layered extension pieces to each other. As a result, the bag bundle can join without all of the engagement holes displacing from each other and, as a result, can easily engage with the external member.
