Description

Technical Field

[0001] This utility model relates to the field of packaging box technology, and in particular to a multi-layer packaging box. Background Technology

[0002] Packaging boxes, as the name suggests, are boxes used to package products. They can be classified by material, such as cardboard boxes, tin boxes, wooden boxes, cloth boxes, leather boxes, acrylic boxes, corrugated boxes, PVC boxes, etc., or by product name, such as mooncake boxes, tea boxes, goji berry boxes, candy boxes, exquisite gift boxes, local specialty product boxes, wine boxes, chocolate boxes, food, medicine, and health product boxes, food packaging boxes, tea packaging boxes, stationery boxes, etc. The functions of packaging boxes include ensuring product safety during transportation and enhancing the product's perceived quality.

[0003] For example, the authorization announcement number "CN215664735U" describes a type of protective packaging box. When the limiting post at the bottom of the upper protective layer is inserted into the limiting hole at the top of the lower protective layer, the relative displacement of the upper protective layer, the lower protective layer, the bottom plate, and the cover plate is restricted, which improves the packaging protection effect of the product. In addition, the protective cap at the limiting hole is not easily worn, which facilitates the reuse of the packaging box. Furthermore, the female buckle inside the protective cap, together with the male buckle at the bottom of the limiting post, enables the bottom plate and the cover plate to have a self-locking and fixing effect after being pressed together, which improves the stability of the packaging box.

[0004] The above-mentioned and existing technologies have the following drawbacks: the packaging box can only hold gifts of the same height, resulting in low utilization of the packaging box and affecting the ability to hold gifts of other heights. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a multi-layer packaging box.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] Design a multi-layer packaging box, including a packaging box body, a placement cavity on the upper surface of the packaging box body, a product inside the placement cavity, a first buffer layer between the lower surface of the product and the lower inner wall of the placement cavity, an anti-tipping device between the lower surface of the first buffer layer and the lower inner wall of the placement cavity, a second buffer layer between the four sides of the product and the four sides of the inner wall of the placement cavity, a first cover slidably connected to the placement cavity above the product, the first cover being fixed to the packaging box body by a locking device, and a second cover at the upper end of the packaging box body.

[0008] Preferably, the locking device includes multiple sets of through-hole units, which are symmetrically arranged on both sides of the packaging box body. Each through-hole unit includes multiple mounting holes arranged in a linear array. The upper surface of the first cover is provided with multiple locking blocks that correspond one-to-one with the through-hole units. Each locking block has a threaded hole on its surface. Each through-hole unit has a screw on its side, and each screw passes through the mounting hole and is threadedly connected to the threaded hole.

[0009] Preferably, the packaging box body has multiple first anti-slip particles on all four sides.

[0010] Preferably, the lower surface of the packaging box body is provided with multiple second anti-slip particles.

[0011] Preferably, the anti-tipping device includes a counterweight plate and a protective plate, the counterweight plate being disposed on the lower inner wall of the placement cavity, and the protective plate being disposed between the first buffer layer and the counterweight plate.

[0012] Preferably, the inner walls on both sides of the placement cavity are provided with multiple positioning blocks, and the two sides of the first cover are provided with multiple positioning grooves that correspond one-to-one with the positioning blocks, and the positioning blocks extend into the positioning grooves.

[0013] This utility model proposes a multi-layer packaging box with the following advantages: The locking device aligns the threaded hole with one of multiple mounting holes, then a screw passes through the mounting hole and connects with the threaded hole to fix the first cover. The second cover is then installed onto the packaging box body. In summary, this packaging box can store gifts of different heights, maximizing its utilization and not affecting the ability to hold products of other heights. The anti-tipping device, due to the weight of the counterweight plate, prevents the packaging box from tipping over during transportation. Attached Figure Description
