Description

B31B covers manufacturing processes and machinery for producing containers, boxes, tubes, and similar hollow articles from paper, cardboard, and paper-like materials. This classification encompasses folding, gluing, forming, and assembly techniques used to create rigid or semi-rigid packaging structures, including corrugated boxes, folding cartons, paper bags, and composite containers. Technologies within this scope range from manual to fully automated systems for die-cutting, scoring, creasing, and bonding paper-based materials into functional containers. Related classes such as B31D address making other paper articles (e.g., envelopes, labels), while B65B covers filling and closing containers after manufacture.
