Carton structure
Technical Field
The invention relates to a carton structure, in particular to a carton structure which is formed by bending a main board body formed by cutting a thin corrugated board, matching two supporting boards and can achieve the effects of weight resistance and no deformation, and the cartons can be stably stacked without the worry of slippage.
Background
Generally, cartons for containing articles for transportation are mostly formed by bending corrugated boards, and the sizes and weights of the contents to be stored and carried by the cartons are different, so that the cartons need to have different strengths, if the cartons are thin, the deformation problem that the top surface or the bottom surface of the cartons are prone to be depressed can occur due to insufficient gravity resistance, and generally, the heavy cartons 1 are mostly formed by five layers of thicker corrugated boards 10 (as shown in fig. 1 and 2), so that the weight resistance of the cartons is increased by the thickness of the boards 10, however, the thicker the thickness of the cartons 1, the heavier the weight of the cartons, the higher the cost, and the general cartons 1 cannot be stably positioned when being stacked, so that the cartons 1 can be moved (as shown in fig. 3), and the articles in the contents can be easily dropped.
