Patent Name Packing Box with Buffer Structure Patent Applicant Knife Handler Co., Ltd. Principal Applicant Address Taiwan Province Taipei County Inventor Liao Qinghua Application (Patent) No. 200420085148.1 Application Date 2004.08.10 Certification Date Auditing Announcement No. 2723369 Auditing Announcement Date 2005.09.07 Instruction CD-ROM D0536 Main classification number B65D81/02 Classification number B65D81/02; B65D85/68 Division Original application number Priority Claims Abstract This disclosure relates to a packaging box with a buffer structure, which is used for sheathing. In the electronic and computer-related products, the internal packing box structure provides a cushioning effect. The packing box is a first frame, a second frame and a pair of frame-like body-engaging structures made entirely of corrugated cardboard. In other words, the formation of the first frame, the second frame, or both sides of the frame, and the connection between the two frames is entirely using the concave-convex flap-engagement structure of the corrugated paper itself, and no adhesive is used there between. , nailing, gluing and other joint methods, therefore, 100% of the materials used for recycling, regeneration, and no pollution, and because no pollution, so Collection, re-use without any negative impediments, costs, equipment is minimized. Sovereignty item 1, a packing box with a buffer structure, characterized in that it comprises a first frame body, a second frame body and two side frame bodies, wherein: the first frame body is formed by cardboard along a fold line The bottom forming plate, the end wall forming plate and the foot forming plate are connected to each other. The bottom forming plate is formed with two slots. The end wall forming plate is formed by folding the end wall plate, the auxiliary plate and the bottom plate along the fold line. And standing on one side of the bottom forming plate, and the end wall forming plate forms a bent plate through a convex tangent at a position spanning the auxiliary plate and the end wall plate, so that the bent plate is folded along the fold line and can be bent at the end wall The upper part of the board protrudes and extends on one side, and the end wall forming board corresponds to the bottom part to form a two-slot position on the board to form a rectangular tab to insert and the fixing board is erected, and the foot part forms the outer wall board and the top board, The inner side wall board and the bottom board are folded along the fold line and stand upright on the side of the bottom forming board, and the foot forming board corresponds to the bottom forming the two slots on the board to form rectangular tabs to insert and the fixing board is erected, and at the other end The wall forming plate and the foot forming plate are adjacent to each other The side ends are respectively formed with a fitting groove, and the end wall forming plate is respectively provided with a longitudinal cutting fitting groove on both sides above the auxiliary plate; the second frame body is a bottom forming plate connected by a cardboard along a curved line. The end wall forming plate and the foot forming plate form two slots on the bottom forming plate. The end wall forming plate is formed by folding the end wall plate, the extension plate and the bottom plate along the fold line, and stands upright at the bottom to form a plate. The side, and the semi-convex round groove at the middle of the end wall forming plate form an accommodating space with a longitudinal opening facing upward after being bent, and the end wall forms a plate corresponding to the bottom and forms two rectangular slots on the plate to form a rectangular lug insert. The fixing plate is erected, and the side wall plate, the top plate, the inner wall plate and the bottom plate of the leg forming plate are folded along the fold line, and stand upright on the side of the bottom forming plate, and the foot forming plate corresponds to the bottom. A rectangular tab is inserted into the two slot positions on the board to insert the fixing plate, and the mounting plate is formed on both sides of the end wall forming plate and the leg forming plate. The end walls are formed on the extension plate. Semi-convex circle with longitudinal opening upwards A longitudinally-cutting fitting groove is respectively formed on one side of the upper side; and the two side frames are formed by two pieces of the bottom buckle plate, the end wall forming plate, the top plate and the bending extension plate which are connected by a cardboard along a curved line. The end wall forming plate, the top panel and the folded extension board are folded along the fold line and are erected on top of the two bottom buckle plates. The bottom buckle plate forms a card slot longitudinally in the middle and the top panel side. A long piece of flap is formed, and a longitudinal groove is formed on both sides of the bent extension plate. The card slots of the two side frame body and the bottom buckle plate are respectively inserted into the first and second frames. In the fitting grooves on both sides of the adjacent end wall forming plate and the foot forming plate, and the fitting grooves on both sides of the bending extension plate on both sides of the frame are respectively inserted into the auxiliary plates above the first frame, both sides are embedded. In the two grooves on the two sides of the extension plate of the second casing, the top panels of the two frame bodies are extended downward to form long flaps inserted into the two-side fitting grooves above the auxiliary plate of the first casing.
