| 目的 针对现有快递包装普遍使用胶带封箱及生命周期短等问题，提出一种免胶带封箱可自锁且可多次使用的新型瓦楞纸箱设计方案。方法 首先确定包装材料;接着进行创新性包装结构设计，重点设计免胶带封箱及自锁结构的可靠性;在此基础上确定纸箱多次使用的工艺流程;最后利用验证试验及有限元仿真对纸箱进行性能分析。结果 自由跌落试验结果表明提案纸箱在多次使用过程中具有良好的封箱强度;跌落仿真结果表明提案纸箱可吸收约40%的外部冲击载荷，具有良好的缓冲性能;空箱抗压仿真可知提案纸箱的最大抗压强度为3236 N，较普通开槽箱抗压性能提升约42%。另外，提案纸箱较普通开槽箱可降低约60%的生产成本。结论 提案纸箱具有免胶带封箱、自锁防盗启、生命周期长、保护性能好、生产成本低等优点。 |

| The work aims to propose a tape-free corrugated box which has self-locking function and can be used for many times in view of the usage of the tape seal and the short life cycle of express package. Firstly, the packaging material was determined. Secondly, an innovative structural design of the package was carried out to highlight the reliability of tape-free sealing and self-locking structure. In addition, the recycling process of the proposed box was clarified. Finally, the dynamics performance of the proposed box was analyzed by the verification tests and finite element simulations. The results of free drop test showed that the proposed box had good sealing strength after multiple uses. The drop simulation test results showed that the proposed box could reduce about 40% of the external impact load and had good cushioning performance. The maximum compressive strength of the proposed box was 3236 N, which was about 42% higher than that of the traditional slotted case. Besides, the production cost of the proposed box could decrease by about 60% compared with the traditional slotted case. The proposed box has the advantages of tape-free sealing, self-locking and anti-theft opening function, long life cycle, good protection performance, low production cost, etc. |
