[0002] EPE is also known as pearl cotton. Polyethylene foam is a non-crosslinked closed-cell structure and is a new type of environmentally friendly packaging material. It is composed of countless independent bubbles generated by physical foaming of low-density polyethylene resin. It overcomes the disadvantages of ordinary foaming glue being fragile, deformed, and having poor resilience. It has many advantages such as water resistance, moisture resistance, shock resistance, sound insulation, heat preservation, good plasticity, strong toughness, recyclability, environmental protection, and strong impact resistance. It also has good chemical resistance and is an ideal substitute for traditional packaging materials.

[0003] For the packaging of some square valuable items, EPE foam is often filled inside the carton, which can not only improve the overall structural strength of the carton but also protect the square valuable items inside. For the same type of valuable items with different sizes, the sizes of the cartons used and the sizes of the foam filled inside are mostly different, which undoubtedly increases the production cost during manufacturing. Therefore, we propose an EPE foam structure for cartons to solve the above problems. Content of the Utility Model

A plurality of first connection grooves are opened on the inner wall of the installation groove. Openings are provided on one side of the first side foam and the second side foam. A plurality of second connection grooves are opened on the inner wall of the opening. Plug blocks are clamped on the inner walls of the first connection grooves and the second connection grooves. An adjustment block is fixedly installed between adjacent two of the plug blocks.

[0006] Further, the outer walls of the side foams and the movable foam are both inclined, and the positions of the first connection grooves and the second connection grooves on the same side are adapted to each other.

[0007] Furthermore, the outer foam structure is attached to the inner wall of the box body, and the edge foam is L-shaped.

[0008] Furthermore, a sliding groove is formed inside the edge foam, and the movable foam is slidably installed on the inner walls of two adjacent sliding grooves.

[0009] Furthermore, a plurality of positioning grooves are formed on the upper surface of the bottom foam, and a plurality of positioning blocks extending into the positioning grooves are fixedly installed at the bottoms of the first side foam and the second side foam.

[0010] Furthermore, a sliding groove is formed on one side of the first side foam close to the second side foam, and a sliding block extending into the sliding groove is fixedly installed on one side of the second side foam close to the first side foam.

[0011] Furthermore, two limiting plates are fixedly installed on the surface of the movable foam, and both of the two limiting plates are located outside the installation groove.

[0030] It should be noted that during the adjustment of the inner foam structure 3, when the four movable foams 302 move towards or away from each other, the four edge foams 301 will also move closer to or away from the middle of the box body 1. When the size of the inner foam structure 3 becomes smaller, the movable foam 302 will move towards the inside of the edge foam 301. Conversely, when the size of the inner foam structure 3 becomes larger, the movable foam 302 will move towards the outside of the edge foam 301.

[0031] Please refer to Figure 6 and Figure 7 In this embodiment, the outer foam structure 2 is attached to the inner wall of the box body 1.

[0034] Among them, the sliding groove 14 and the sliding block 13 are provided for splicing between the second side foam 203 and the first side foam 202.

[0035] In addition, by dividing the outer foam structure 2 into the bottom foam 201, the first side foam 202 and the second side foam 203, it is assembled in a detachable and spliced manner, which undoubtedly reduces the occupied space when discarded or placed, and improves the convenience of the structure.

[0036] Please refer to Figure 3, in this embodiment, two limit plates 10 are fixedly installed on the surface of the movable foam 302, and both of the two limit plates 10 are located outside the installation groove 5.

[0037] Among them, the limit plates 10 are provided to prevent the movable foam 302 from completely extending into the side foam 301.

[0038] It should be noted that the limit plates 10, the adjusting blocks 9, the inserting blocks 4, the sliding blocks 13 and the positioning blocks 11 are all made of EPE foam.

[0039] When this embodiment is in use, place the item inside the inner foam structure 3, remove the adjusting block 9, adjust the position of the inner foam structure 3 so that its inner wall fits the outer wall of the item, and then insert the inserting blocks 4 at both ends of the adjusting block 9 into the corresponding first connection grooves 6 and second connection grooves 8. In this way, the protection of the item can be completed. There is no need to prepare various fillers of different specifications for items of different sizes, reducing the inventory cost, simplifying the logistics process, and also reducing the production cost of the foam. When disassembling, directly take out the inner foam structure 3, then pull out the second side foam 203 upwards, and then remove the first side foam 202 and the bottom foam 201 respectively. In this way, the occupied space can be reduced when discarding or placing, improving the convenience of this structure.
