<p>A carton structure (10) comprises an upper cover (100) and a lower cover (200). The upper cover (100) comprises a plurality of first sidewalls (120) and a plurality of first tongues (130) connected with the first sidewalls (120), wherein the first tongues (130) are used for being fixed to the inner surfaces of the adjacent first side walls (120). The lower cover (200) comprises a plurality of second sidewalls (220) and a plurality of second tongues (230) connected with the second sidewalls (220), wherein the second tongues (230) are used for being fixed to the inner surfaces of the adjacent second sidewalls (220). The lower cover (200) further comprises reinforcing pieces (240) connected to part of the second sidewalls (222) and located on the outer sides of the second sidewalls (222). When the lower cover (200) is externally sheathed by the upper cover (100), the reinforcing pieces (240) serve to fill in gaps between the upper cover (100) and the lower cover (200) that result from the first tongues (130).</p> |
