cushioning packaging structure and packaging box

Abstract

A cushioning packaging structure includes a sheet material having a front and a back. The front is provided with a plurality of notches, dividing the sheet material into a plurality of blocks. At least one block is provided with at least one hollow portion for inserting an item to be fixed. The sheet material can be bent along each notch to form a cushioning structure. The design of the notches allows the sheet material to be folded to increase the cushioning strength.

Claims

1. A cushioning packaging structure comprising: a sheet material having a front side and a back side, the front side having a plurality of notches to divide the sheet material into a plurality of blocks, wherein at least one of the blocks has at least one perforation, and the sheet material is bent along each of the notches to form a cushioning structure.

2. The cushioning packaging structure as described in claim 1, wherein the number of notches is four, the notches dividing the sheet material into a first block, a second block, a third block, a fourth block and a fifth block connected in sequence, the third block having the at least one cutout, the sheet material being bent along each of the notches, and the blocks being arranged in sequence to form a cushioning structure having a cushioning space, the cushioning structure being rectangular.

3. The cushioning packaging structure as described in claim 2, wherein the first block and the fifth block join together after the sheet is bent, so that the cushioning structure forms a closed rectangular structure.

4. The cushioning packaging structure as described in any one of claims 1 to 3, wherein each of the notches has a first inclined surface and a second inclined surface, the angle between the first inclined surface and the second inclined surface being 90 degrees, such that the first inclined surface and the second inclined surface fit together after the sheet is bent along each of the notches.

5. The cushioning material structure as described in claim 4, wherein the material is a single-layer foam or a multi-layer foam.

6. The cushioning packaging structure as described in claim 5, wherein the thickness of the sheet material is between 1.5 cm and 6 cm.

7. The cushioning packaging structure as described in claim 1, wherein each of the blocks is sequentially arranged to form a cushioning space, and at least one of the blocks is bent toward the cushioning space to form a reinforcement.

8. The cushioning material structure as described in claim 7, wherein, The sheet has five notches, dividing it into a first block, a second block, a third block, a fourth block, a fifth block, and a sixth block that are connected in sequence. The sixth block is bent toward the buffer space to form the reinforcement.

9. The cushioning structure as described in claim 1, wherein the cushioning structure is secured by a fastener.

10. A packaging box having a receiving space and at least two cushioning packaging structures as described in claim 1, respectively disposed on opposite sides of the receiving space.
