Shimaoka’s Lock (A New Fixation Method in Cardboard)
Company:
DYNAPAC CO.,LTD.
Country: Japan
Category: Other
Conventionally, folded corrugated cardboard was mainly fixed with adhesive tape and complicated lock structures,
which was hard work.
To settle this, an easy lock structure from only folding the corrugated sheet has been developed.
Adding the shifted score lines and zigzag notches, the adjacent parts can be engaged when folded.
