Abstract

The present disclosure provides a packaging structure. The packaging structure may include a sheet and a film. The sheet may include a base plate and a first side plate, a second side plate, a third side plate, and a fourth side plate. The film may at least include a first fixed part and a second fixed part. The first fixed part and the second fixed part may be fixedly connected with at least two side plates of the first side plate, the second side plate, the third side plate, and the fourth side plate, respectively. The packaging structure may achieve the purpose of stretching the film through the folding of the plurality of side plates, so that the film and the bottom plate may form a packaging space to effectively package and fix an object, thereby improving the reliability of transportation.

First claim

What is claimed is:

1. A packaging structure, comprising:
a sheet including a base plate and a first side plate, a second side plate, a third side plate, and a fourth side plate, the first side plate, the second side plate, the third side plate, and the fourth side plate being distributed around the base plate; and
a film at least including a first fixed part and a second fixed part, the first fixed part and the second fixed part being fixedly connected with at least two side plates of the first side plate, the second side plate, the third side plate, and the fourth side plate, respectively, wherein,
the first side plate is disposed opposite to the third side plate, and the second side plate is disposed opposite to the fourth side plate, the first fixed part and the second fixed part of the film are fixedly connected with the first side plate and the third side plate respectively, wherein
a plurality of cutting lines are disposed on the film to form a plurality of stretching holes;
the film includes only one display region in a central region of the film and two non-display regions, the two non-display regions are located at two opposite sides of the central region, respectively, along a longitudinal direction of the film from the first side plate to the third side plate, the plurality of cutting lines are only distributed at the two non-display regions such that the display region is a smooth region for displaying a packaged object.

2. The packaging structure of claim 1 , wherein the plurality of cutting lines include an arc line or a straight line.

3. The packaging structure of claim 1 , wherein the plurality of cutting lines are evenly distributed in a region of the film.

4. The packaging structure of claim 1 , wherein:
the base plate includes a first sub-base plate and a second sub-base plate, and a folding line disposed between the first sub-base plate and the second sub-base plate;
the second side plate includes two second sub-side plates disposed on either side of the folding line; and
the fourth side plate including two fourth sub-side plates disposed on either side of the folding line.

5. The packaging structure of claim 1 , further comprising:
a box body plate, the box body plate including a box base plate, a first folding plate, a second folding plate, a third folding plate, and a fourth folding plate, the first folding plate, the second folding plate, the third folding plate, and the fourth folding plate being distributed around the box base plate, wherein,
the first folding plate is disposed opposite to the third folding plate, and the second folding plate is disposed opposite to the fourth folding plate; and
the fourth folding plate is connected with the sheet at a side facing away from the box base plate.

6. The packaging structure of claim 5 , wherein the second folding plate is connected with a cover plate at a side facing away from the box base plate, and the cover plate is disposed opposite to the box base plate in a folding state of the packaging structure.

7. The packaging structure of claim 1 , wherein the film is configured to fasten an object at a packaging area of the packaging structure, and an area of the film is smaller than that of the packaging area.

8. The packaging structure of claim 7 , wherein the film has a plurality of sub-films, each of which includes a fixed part and a packaging part, the fixed part of each sub-film connected with at least part of the at least two side plates, the packaging part of each sub-film covering at least part of the object to fasten the object in the packaging structure.

9. The packaging structure of claim 8 , wherein the fixed part of each sub-film is fixedly connected with two adjacent side plates of the first side plate, the second side plate, the third side plate, and the fourth side plate respectively, the packaging part of each sub-film corresponding to an angle part of the base plate.

10. The packaging structure of claim 9 , wherein a count of the sub-films is between the range of 2 to 4, the fixed part of each sub-film being disposed outside of the base plate.

11. The packaging structure of claim 8 , wherein the fixed part of each sub-film is fixedly connected with two opposite side plates of the first side plate, the second side plate, the third side plate, and the fourth side plate, respectively.

12. The packaging structure of claim 1 , wherein the first supporting plate is connected with a margin of the base plate by a first folding line, the second supporting plate is connected with a margin of the base plate by a second folding line, wherein the first folding line is disposed opposite to the second folding line.

13. The packaging structure of claim 12 , wherein two first cutting lines and a second cutting line are disposed on the base plate, both ends of each first cutting lines being connected with the first folding line and the second folding line, the second cutting line being connected with the two first cutting lines.

14. The packaging structure of claim 1 , wherein the film is configured to fasten an object when being stretched by folding the first side plate and the third side plate towards a back of the base plate.

15. The packaging structure of claim 2 , wherein the plurality of cutting lines include a semi-arc shape, an angular shape, or two semi-arcs connected via a straight line.

16. The packaging structure of claim 6 , wherein the fourth folding plate is connected with the fourth side plate at the side facing away from the base plate.

17. The packaging structure of claim 11 , wherein the at least part of the object includes at least one of an angle part, an edge part, and a central part of the object.

18. The packaging structure of claim 1 , wherein each of the plurality of cutting lines includes two semi-arcs connected via a straight line.

19. The packaging structure of claim 18 , wherein the two semi-arcs are two symmetrically disposed semi-circular cuts whose bending directions are opposite.

20. The packaging structure of claim 1 , wherein the plurality of cutting lines have different shapes.
