Cover body structure of square paper box

Abstract

The invention provides a cover body structure of a square paper box. The cover body structure comprises a square cylindrical body with four side walls and a cover body; the cover body comprises an outer cover and a supporting cover; the outer cover is integrally connected to the top of the first side wall of the body; a first supporting cover integrated with the second side wall is arranged at theposition, adjacent to the first side wall, of the top of the second side wall; and the first supporting cover is bent in the direction of the body and then overlapped to the position, opposite to thesecond side wall, of the upper part of the third side wall. The cover body structure of the square paper box has the beneficial effects that since the supporting cover can be overlapped onto the sidewall of the opposite side, the better supporting action is achieved on the outer cover, the pressure bearing capacity is improved, meanwhile, since use of thick paperboards or additional arrangementof supporting frames is avoided, the cost is saved, and environmental protection is facilitated.

Description

technical field [0001] The invention relates to a square carton, in particular to a cover structure of the square carton. Background technique [0002] As a packaging material, cartons are widely used, especially the cartons that are folded into cubes are the most common. There are also two auxiliary covers folded inwardly under the existing carton top cover, such as Figure 8 As shown, the upper cover 1 is pressed on the auxiliary cover 2, and the length of the two auxiliary covers 2 is smaller than the width of the carton, and there is another support frame 3 in some cartons. The disadvantage of the existing carton is that when the middle part of the upper cover is deformed into the box under pressure, the front end of the auxiliary cover will be pressed down due to no support, and the upper cover cannot be effectively supported. When the stacking is too high or the upper and lower covers are subjected to external forces Easily deformed when squeezed. In order to protect...

Problems solved by technology

However, this method of improving the pressure bearing capacity of the carton will increase the cost of the carton and waste resources, especially when the pressure on environmental protection is increasing, the waste of resources also means more pollution in the production process
