Carton with detachable buffer plate set

Abstract

A carton with a detachable buffer plate set includes a bottom plate, two long side plates, an upper cover, two short side plates, two reinforcing side plates, and a detachable buffer plate set. The long side plates and the short side plates are connected to the bottom plate. The upper cover is connected to one of the long side plates. The two reinforcing side plates are connected to the two short side plates respectively. The detachable buffer plate set is detachably connected to one of the reinforcing side plates. Accordingly, by detaching the detachable buffer plate set for supporting and buffering, products of similar size or products with accessories of different sizes may use the same-sized cartons and paper-plastic boxes, so that extra die-cutting costs and storage costs are avoided.
