Description

Technical Field

[0001] The utility model relates to a glue-free express packaging box for a mobile phone, which is applied in the field of mobile phone express packaging. Background Art

[0002] The statements in this section merely provide background information related to the present disclosure and may not constitute prior art.

[0003] At present, the largest channel for mobile phone sales is the e-commerce channel (such as JD.com, Douyin Mall, Pinduoduo, etc.). Therefore, most mobile phones are delivered to users by express delivery, and during the express delivery process, a transport box needs to be put outside the mobile phone sales box. At present, most of these transport boxes use 0201 type corrugated paper boxes that meet the national standard GB / T 6543-2008, and then use BOPP self-adhesive tape to wrap and seal the paper box. The inner lining mostly uses plastic film inflatable cushions as buffer structures. However, this type of packaging currently has the following two main problems:

[0004] 1. A large amount of BOPP adhesive tape is needed for packaging, and after the transport packaging box is discarded, the BOPP adhesive tape is not easy to separate from the paper box, which greatly affects the recycling of the packaging box. At the same time, the discarded BOPP adhesive tape is extremely difficult to degrade in the natural environment, which will cause environmental pollution;

[0005] 2. The plastic film inflatable cushion used in the lining cannot be naturally degraded after being discarded, which will pollute the environment, and it is very easy to lose its cushioning effect due to air leakage during transportation.

[0006] Therefore, it has become an urgent task to provide a mobile phone glue-free express packaging box that does not require self-adhesive tape during packaging, is low in cost, environmentally friendly, has good firmness, and has reliable sealing. Utility Model Content

[0007] In order to overcome the problem that existing mobile phone express packaging requires a large amount of self-adhesive tape, and after the packaging is discarded, the self-adhesive tape is not easy to separate from the paper box, which has the disadvantages of high packaging cost and being environmentally unfriendly, the utility model provides a mobile phone glue-free express packaging box, which is equipped with specially designed locking tongues on both sides of the outer box clamping plate on the box cover and the outer box clamping groove. After buckling, the structure needs to be destroyed before the outer box can be opened. It has the advantages of no need for self-adhesive tape during packaging, low cost, environmental protection, good firmness and sealing reliability.

[0008] The technical solution of the utility model is as follows:

[0074] During the transportation and handling of packages, vibration and impact are the main causes of product damage. Among various impact environments, drop impact is the most direct factor that damages packages, which is extremely harmful to packages. As a kind of express packaging, cartons are required not to be mechanically damaged by external impact or vibration during the entire transportation process, and the outer packaging will not be opened due to the ups and downs of the road surface. Therefore, actual transportation tests were carried out on the cartons. In order to verify whether the cartons have good impact resistance and sealing reliability after multiple uses, a free drop test was first carried out. Test method: Refer to GB / T4857.5 and use a free drop tester to carry out a drop test on the packages. The test results are as follows: In the drop test results of the glue-free express packaging box for mobile phones in this case, except for slight damage to the corners, there was no damage to other parts.

[0075] 2. Packaging compression test

[0076] The compressive strength of corrugated boxes refers to the maximum pressure and deformation when the box is damaged by a pressure testing machine that uniformly applies dynamic pressure at a certain speed, generally in "N" (Newton). Compressive strength is one of the most important quality indicators of corrugated boxes. There are many influencing factors, mainly changes in raw material properties (including cardboard quantity, corrugated flute type, cardboard strength and adhesive type, etc.), structural design (including grooving, opening, reinforcement and other structural forms), production and manufacturing (including printing, pressing, etc.) and circulation and transportation environment (including stacking, storage time and relative humidity). Domestic and foreign scholars have done a lot of research on this. The basic principle of the compression test is to place the test product between the pressure plates of the carton compression machine and pressurize it until the sample is damaged or reaches the predetermined load and displacement value. This has led to three compression test modes, namely "fixed pressure to measure deformation", "fixed deformation to measure pressure resistance" and "maximum crushing force". Compression strength test method: Refer to GB / T4857.4 standard "Basic test for packaging and transport packages", and use a carton compression tester to conduct a compression test on the empty box sample. The test results are as follows:

[0077] 1. Constant pressure deformation test

[0078] Table 1 Deformation measurement effect at constant pressure (recorded 3 times)

[0079]

[0080] 2. Constant deformation test pressure resistance test

[0081] Table 2 Deformation resistance effect (recorded 3 times)

[0082]

[0083]

[0084] 3. Maximum crushing force test

[0085] Table 3 Maximum crushing force test results (recorded 3 times)

[0086]

[0087] It can be seen that the deformation of the mobile phone glue-free express packaging box under constant pressure is smaller than that of the comparison sample, and the compressive strength and maximum crushing force under constant deformation are greater than those of the comparison sample. That is, the compressive resistance of the mobile phone glue-free express packaging box in this case is better than that of the comparison sample.

[0088] 3. Stacking experiment

[0089] Goods need to be stored and kept multiple times during the circulation process. In order to improve the utilization rate of storage space, goods are usually stacked. In the process of storing goods, it is necessary to ensure the safety of goods, and the goods stacked on the bottom layer must not be crushed or deformed. In order to improve the utilization rate of storage space, when products are placed in cartons for storage or transportation, cartons are generally in a stacked state. The cartons on the upper layer will exert a certain pressure on the cartons on the lower layer. If this pressure exceeds the tolerance range of the cartons on the lower layer, the cartons on the lower layer will deform or even be crushed. Therefore, the stacking capacity of cartons is one of the factors that should be considered before stacking cartons. According to the number of stacking layers of the sample and the pressure of each layer, calculate the pre-pressure applied to the sample, and maintain the pre-pressure within a specified time or maintain the pre-pressure until the sample is damaged. The stacking capacity of the sample is determined by measuring the size change of the sample or recording the time when the sample is damaged.

[0090] M=0.38kg,H W =1000mm, Ho=92mm

[0091] N = INT (1000 / 92) - 1 = 6

[0092] F=9.81×1×0.38×[INT(1000 / 92)-1]≈38N

[0093] Where, M is the total mass of a single carton package, kg

[0094] H W ——The maximum effective stacking height during circulation, mm

[0095] Ho——Corrugated box height, mm

[0096] N——Number of stacking times

[0097] F——load.

[0098] The test results are as follows:

[0099] Table 4 Stacking test results

[0100]

[0101] It can be seen that the deformation of the glue-free express packaging box for mobile phones in this case is much lower than the allowable deformation of 6mm of the traditional 0201 box, that is, its deformation is within the allowable deformation range, and the stacking capacity of this solution is qualified.

[0102] 4. Summary: The free drop test results show that the mobile phone glue-free express packaging box has good cushioning performance and sealing reliability; the packaging (empty box) compression test results show that the mobile phone glue-free express packaging box has good sealing and compression protection. The stacking test results show that the mobile phone glue-free express packaging box is resistant to stacking and has good compression resistance.
