Abstract
A backward-folded opening-resistant container structure includes first and second casing members combinable with each other. The first casing member has an outer side to which a foldable member that includes an insertion trough and an engaging member is connected. The second casing member includes a grip portion having a notch. A break-away unit includes a planar portion connected to the notch by means of a perforation line and a fastening portion in the form of a hollow cylindrical body having an end formed with an opening connected to the planar portion. The insertion trough and the fastening portion are combinable with each other, and the foldable member is foldable to have the engaging member inserted into the opening. When the first casing member and the second casing member are separated, the perforation line is broken and the break-away unit detaches from the second casing member.
