AI Technical Summary
Because the single-layer structure of the double-insert box is extremely susceptible to stress deformation, the product is easily crushed or shaken during transportation, and cannot be effectively fixed, resulting in damage.
An anti-extrusion-free sealing buttable packaging box is designed. By providing a limit buffer assembly on the main body of the carton, including a side buffer unit and an end-surface buffer unit, it uses adhesive strips, limit strips, extrusion plates and buffer plates. The combined structure of the product realizes limiting and buffering, and avoids contact between the product and the outside of the box.
It effectively avoids the product's shaking and extrusion damage inside the box, ensuring that the product is not damaged during transportation, and prevents direct extrusion of the product when the outside of the box is subjected to stress, improving the safety of the packaging.

[0003] The double-insert box is a box structure with both upper and lower ports that can be opened. It is commonly used for the packaging of electronic, food, medicine, health care products, cosmetics, toys and other products. The double-insert box is formed by punching a piece of cardboard and then folding it. It has a simple structure and is easy to form. However, due to its single-layer structure, it is very easy to deform under force. If the product fits tightly against the inner cavity of the double-insert box, it will easily cause the product to be squeezed and damaged.

[0029] In this embodiment, when assembling the packaging box, the operation steps are as follows:
[0030] First, place the first buffer plate 204 and the second buffer plate 208 on the first side 102, the second end 103, the second side 104, and the upper surface of the cross-section joint edge 105 respectively, take the first adhesive strip 201, the first limiting strip 202, the second adhesive strip 205, and the second limiting strip 206 as a whole, and bond them to the first side 102, the second end 103, the second side 104, and the cross-section joint edge 105 (it should be supplemented that: the lower surfaces of the first adhesive strip 201 and the second adhesive strip 205 are coated with adhesive), at this time, the first limiting strip 202 is attached to the upper surface of the first extrusion plate 203, and the second limiting strip 206 is attached to the upper surface of the second extrusion plate 207;
[0031] Then, the first end edge 101, the first side edge 102, the second end edge 103, the second side edge 104, and the end face contact edge 105 are bent 90 degrees in sequence, and finally the end face contact edge 105 is aligned with the first end edge 101 and the end face contact edge 105 is attached to the inner side of the first end edge 101, and then adhesive is applied to the outer surface of the end face contact edge 105 to bond and fix it to the first end edge 101;
[0032] Then, the opening folded edge 106 at the lower end can be bent 90 degrees toward the inner side of the box body, and then the cover edge 107 at the lower end can be bent 90 degrees to fit the bottom end of the opening folded edge 106 at the lower end, and then the opposite inserting edge 108 can be inserted into the inner side of the box body, and the cover edge 107 can be fixed by the friction between the symmetrical edge 108 and the inner side of the box body;
[0033] At this point, the box body is assembled, and then the product to be packaged is placed inside the box body (it should be noted that the product size is smaller than the inner size of the box body), and then the upper opening folding edge 106 and the cover edge 107 are bent 90 degrees, and the inserting edge 108 is inserted into the inner side of the box body to fix the upper cover edge 107, and the product packaging is completed;
[0034] During the above operation, the opening folded edges 106 at the upper and lower ends are bent 90 degrees to squeeze the second extrusion plates 207 distributed above and below. The two second extrusion plates 207 are close to each other to squeeze the second buffer plate 208 to deform and bend. The bending part of the second buffer plate 208 fits the end surface of the product to limit the end surface of the product.
[0035] The cover edges 107 at the upper and lower ends are bent 90 degrees to squeeze the first extrusion plates 203 distributed above and below. The two first extrusion plates 203 are close to each other to squeeze the first buffer plate 204 to deform and bend. The bending part of the first buffer plate 204 fits the side of the product to achieve the side position limitation of the product. In this way, the product can be fixed inside the box body, effectively avoiding the product shaking and collision inside the box body to cause damage;
[0036] At the same time, when the outside of the paper box body 1 is squeezed, the first end edge 101, the first side edge 102, the second end edge 103, and the second side edge 104 thereof will not directly squeeze the product when deformed by force, and can play the role of preventing squeeze damage.
[0037] Please refer to Figures 1-2 The first end edge 101, the first side edge 102, the second end edge 103, the second side edge 104, and the end face connecting edge 105 are of the same height, and the overall height of the first extrusion plate 203 and the first buffer plate 204 and the overall height of the second extrusion plate 207 and the second buffer plate 208 are greater than the height of the first end edge 101, and a bending line 209 is integrally formed in the middle of the first buffer plate 204 and the second buffer plate 208, and the bending line 209 makes the end face cross-section of the first buffer plate 204 and the second buffer plate 208 in the normal state present a “>” shape.
[0038] In this embodiment: through the above structure, when the opening folding edge 106 and the cover plate 107 are bent 90 degrees, the first extrusion plate 203 and the second extrusion plate 207 can be extruded and moved, thereby providing power for the deformation of the first buffer plate 204 and the second buffer plate 208;
[0039] In addition, the bending line 209 makes the deformation trajectory of the first buffer plate 204 and the second buffer plate 208 controllable, thereby ensuring the stable deformation of the first buffer plate 204 and the second buffer plate 208.
[0040] Please refer to Figures 1-2 The first adhesive strip 201, the first limiting strip 202, the second adhesive strip 205, and the second limiting strip 206 are integrally formed by a die-cutting process, the first extrusion plate 203, the first buffer plate 204, the second extrusion plate 207, and the second buffer plate 208 are integrally formed by a die-cutting process respectively, and the entire paper box body 1 is integrally formed by a die-cutting process.
[0041] In this embodiment: through this structure, the production of this packaging box only adds the die-cutting and bonding assembly steps of the limit buffer component to the existing paper box production process, which can improve the production on the basis of the existing paper box production and facilitate the promotion of production.
