Description

Technical Field

[0001] The utility model relates to the technical field of packaging, in particular to a buffer packaging structure without binding and glue. Background Art

[0002] Chinese authorized publication number CN219707586U, with the authorization publication date of September 19, 2023, discloses a corrugated paper buffer packaging for a roasting furnace, including an outer box, a bottom support plate, an outer bottom paper card, an inner bottom paper card, and an outer top paper card. The outer box is used to package and carry the external roasting furnace. The bottom support plate is arranged at the inner bottom of the outer box. The outer bottom paper card is arranged on the inner side wall of the outer box. The outer top paper card is arranged at the inner top of the outer box. The inner bottom paper card is inserted into the outer bottom paper card. The outer box, the bottom support plate, the outer bottom paper card, the inner bottom paper card, and the outer top paper card of the utility model are all made of paper materials, providing packaging and buffering for the bottom, side, and top of the external roasting furnace, facilitating the transportation of the external roasting furnace. At the same time, the buffer material for packaging the roasting furnace is green and environmentally friendly. The inner bottom paper card inserted into the outer bottom paper card enhances the buffering performance of the outer bottom paper card. The inner bottom paper card and the outer bottom paper card are modularly assembled, facilitating the replacement of damaged components, simplifying the packaging forming process, and being conducive to the production and processing and forming of the package. The defect of this prior art is that the overall earthquake-resistant and buffering function is weak, especially for some relatively heavy outdoor roasting furnaces.
