摘要

The container is shown in a partially folded state. Adhesive is applied at 19,20,21. After folding about transverse fold lines a "lie flat" collapsible container is obtained. This is erected by lifting out side walls of base and lid. The diagonal fold lines shown extend from a base corner, only partially to the edge of the flaps shown.
