Description

Technical Field

[0001] The utility model relates to the technical field of packaging products, in particular to a packaging box with a buffer structure. Background Art

[0002] As the name suggests, a packaging box is a box used to package products. Protecting goods is one of the important functions of a packaging box. During the circulation process, goods may be affected by various external factors, causing damage, pollution, leakage or deterioration of the goods, which will reduce or lose the use value of the goods. Scientific and reasonable packaging can make the goods resist the damage of various external factors, thereby protecting the goods and ensuring the quality and quantity of the goods are intact.

[0003] Existing packaging boxes are mostly made of paper. After packaging objects, there is a gap between the packaged objects and the packaging box during transportation. The packaged objects will have an impact on the packaging box. Due to the simple structure of paper packaging boxes, the packaged objects directly impact the inner wall of the packaging box, which can easily cause the packaging box to be damaged and deformed.

[0004] In addition, when using paper packaging boxes to pack hard objects with sharp corners, the single-layer packaging boxes are easily punctured by the sharp corners, causing the packaging to be damaged and affecting the transportation safety of the items;

[0005] Therefore, the present application provides a packaging box with a buffer structure to meet the needs. Utility Model Content

[0006] The purpose of the present utility model is to solve the problems existing in the above-mentioned background technology and to propose a packaging box with a buffer structure.

[0007] In order to solve the above technical problems, the present invention provides the following technical solutions:

[0008] A packaging box with a buffer structure comprises: a box body, a box lid, a sealing cover plate, a protective box sleeve, a buffer box, a partition, a limit frame and a support plate. The upper edge of the box body is compounded with the box lid, the front end of the box lid is compounded with the sealing cover plate, the outer end of the box body is bonded with the protective box sleeve, the surface of the box lid is bonded with the buffer box, the surface of the buffer box is provided with a card slot, the inner bottom plate of the box body is bonded with a partition plate, the lower end of the partition plate is provided with a supporting foot, the side of the partition plate is bonded with the limit frame, and the bottom of the limit frame is bonded with the support plate.

[0009] Preferably, the buffer box is trapezoidal in shape and is made of corrugated paper, and the interior of the buffer box is hollow.

[0010] Preferably, there is a gap between the buffer box and the side of the box cover, and the buffer box fits in with the opening of the box body.

[0011] Preferably, the surface of the buffer box is provided with four groups of inwardly recessed long strip-shaped slots, and the four groups of long strip-shaped slots are interconnected as a whole.

[0012] Preferably, two groups of partitions are provided, and the two groups of partitions are located at the left and right ends of the box body. The partitions are arranged vertically, and there is a gap between the partitions and the side surfaces and the front and back surfaces of the box body.

[0013] Preferably, the partition is in a "Y" shape as a whole, and the supporting legs at the bottom of the partition are in a "V" shape.

[0014] Preferably, the limiting frame is in a "concave" shape, and the limiting frame and the partitions on the left and right sides form a rectangular box body.

[0015] Preferably, when the box cover is closed on the box body, the buffer box is nested at the inner upper end of the partition and the limiting frame, and the card slot is embedded at the outer end of the upper edge of the partition and the limiting frame.

[0016] Preferably, several groups of support plates are vertically adhered to the bottom of the limit frame, and there are gaps between the support plates. The side of the limit frame is mounted on the supporting feet of the partition, and there is a gap between the bottom of the limit frame and the inner bottom end of the box body through the support plates.

[0017] Compared with the prior art, the present invention has at least the following beneficial effects:

[0018] 1. A rectangular box body is formed by the limit frame and the partitions on the left and right sides, and there is a gap between the box body formed by the limit frame and the partitions on the left and right sides. When items are placed in the formed rectangular box body, they can bend and deform when subjected to force, thereby cushioning the items placed in the limit frame and wrapping the outer ends of the items to fully cushion the items, which can reduce the impact of the packaged items on the packaging box and greatly improve the overall cushioning of the packaging box; 2. A gap is left between the partition and the sides and front and back sides of the box body, so that the buffer box can be supported on the upper part of the partition and the limit frame after the box lid is closed, with the outer part of the card slot of the buffer box filled in the gap. The buffer box can not only seal the upper end openings of the partition and the limit frame, but also ensure the three-dimensionality of the partition and the limit frame, thereby effectively enhancing the strength of the buffer structure.
