ABSTRACT:
A container fastener system which facilitates construction and use of containers formed of tri-wall or other multi-layer corrugated paper board is disclosed. Plate and clip fastening systems particularly adapted for interconnection of panels in overlapping relationship are disclosed. The arrangement facilitates adhesive attachment of the plate components to the panels and the attachment and interconnection of the plate components by clip members without penetration of the surfaces of the panels. One plate component of each pair is provided with a retainer flange which prevents lateral separation of one panel with respect to the other so as to maintain the integrity of the container when the panels are fastened together.
