Abstract
Description
Technical Field
[0001] This utility model belongs to the field of paper packaging box technology, specifically relating to a protective paper packaging box. Background Technology
[0002] Paper packaging boxes are made of paper products and are used to package various items. They are divided into single-wall, double-wall, triple-wall, and quadruple-wall cartons. Cartons are further subdivided into paper boxes, color boxes, and extra-large, oddly shaped die-cut boxes, etc. Cartons are low in cost, easy to seal, suitable for adding fillers, and clean, making them suitable for product packaging, goods transportation, and material handling.
[0003] Existing paper packaging boxes have a simple structure, and the box itself is prone to deformation during use. Furthermore, when the box is transported, the bottom of the box comes into contact with the ground, making it susceptible to moisture. Therefore, we propose a protective paper packaging box. Utility Model Content
[0004] The purpose of this invention is to provide a protective paper packaging box to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a protective paper packaging box, comprising a box body, a box cover on the top of the box body, a reinforcing strip on the outer edge of the box cover, reinforcing corner edges on the outer side of the box body, a reinforcing base at the bottom of the box body, a support at the bottom of the reinforcing base, a buffer groove on the inner side of the box body, a honeycomb plate on the inner side of the buffer groove, a reinforcing plate inside the box body, mounting holes on the surface of the reinforcing plate, a foam layer on the inner side of the mounting holes, and a moisture-proof board at the bottom of the inner side of the box body.
[0006] Preferably, a lid is snapped onto the top of the box body, and reinforcing strips are fixedly connected to the four outer sides of the lid.
[0007] Preferably, a reinforcing corner edge is fitted onto the outer connecting corner of the box body, and a reinforcing base is fitted onto the bottom of the box body.
[0008] Preferably, a support is fixedly connected to the bottom of the reinforcing base, a buffer groove is provided in the middle of the box, and a honeycomb panel is fixedly installed on the inner side of the buffer groove.
[0009] Preferably, reinforcing plates are fixedly installed on the four inner sides of the housing, and mounting holes are provided through the surface of the reinforcing plates.
[0010] Preferably, a foam layer is fixedly installed inside the mounting hole, and a moisture-proof board is laid on the inner bottom surface of the box.
[0011] Compared with the prior art, the beneficial effects of this utility model are:
[0012] By adding reinforcing strips, corners, and a base, the overall protective strength of the outer side of the enclosure is increased. The buffer grooves and honeycomb panels enhance the impact resistance of the enclosure itself. The reinforcing plates and foam layers further improve the compression resistance and overall protection of the enclosure. The supports and moisture-proof boards improve the moisture-proof effect of the bottom of the enclosure, preventing moisture from affecting its performance. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0018] Please see Figure 1-3 This utility model provides a technical solution: a protective paper packaging box, including a box body 1, a box cover 2 on the top of the box body 1, a reinforcing strip 3 on the outer edge of the box cover 2, a reinforcing corner edge 4 on the outer side of the box body 1, a reinforcing base 5 at the bottom of the box body 1, a support 6 at the bottom of the reinforcing base 5, a buffer groove 7 on the inner side of the box body 1, a honeycomb board 8 on the inner side of the buffer groove 7, a reinforcing plate 9 inside the box body 1, mounting holes 10 on the surface of the reinforcing plate 9, a foam layer 11 on the inner side of the mounting holes 10, and a moisture-proof board 12 on the inner bottom of the box body 1.
[0019] Specifically, a lid 2 is snapped onto the top of the box body 1. Reinforcing strips 3 are fixedly connected to the four outer sides of the lid 2. Reinforcing corner strips 4 are fitted onto the outer corners of the box body 1. A reinforcing base 5 is fitted onto the bottom of the box body 1. A support 6 is fixedly connected to the bottom of the reinforcing base 5. A buffer groove 7 is opened in the middle of the box body 1. A honeycomb board 8 is fixedly installed on the inner side of the buffer groove 7. Reinforcing plates 9 are fixedly installed on the four inner sides of the box body 1.
