Description

Technical Field

[0001] The utility model relates to a glue-free express packaging box, which is particularly applicable to the express packaging field of bottle-shaped objects. 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, during the express delivery of bottle-shaped objects (without their own sales packaging, such as shampoo bottles, etc.), the bottles are generally placed directly in express packaging boxes (mostly 0201-type corrugated paper boxes that comply with the national standard GB / T 6543-2008), filled with plastic film air cushions, and then wrapped and sealed with BOPP self-adhesive tape. However, during the express delivery, bottles are still easily broken by external collisions and impacts, especially for fragile parts such as bottlenecks, which need to be specially protected.

[0004] However, this type of packaging currently has the following two main problems:

[0005] 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;

[0006] 2. Using BOPP adhesive tape is not only inconvenient to seal the box, but also inconvenient to open the box;

[0007] 3. The plastic film inflatable cushion used for filling 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.

[0008] Therefore, it has become an urgent task to provide a glue-free express packaging box that does not require self-adhesive tape during packaging, is easy to use, low in cost, environmentally friendly, has good firmness, and has reliable sealing. Utility Model Content

[0009] In order to overcome the problem that the existing express packaging of bottle-shaped objects requires a large amount of self-adhesive tape, and after the packaging is discarded, the self-adhesive tape is not easy to be separated from the paper box, which has the disadvantages of high packaging cost, inconvenience in use, and environmental pollution, the utility model provides a glue-free express packaging box, which is cross-connected with the first and second clamping grooves of the outer box respectively by the mutual clamping cooperation of the first clamping plate and the second clamping groove of the outer box, and in particular, a locking tongue is provided on the second clamping plate of the outer box to cooperate with the movable gap of the second clamping groove of the outer box, so that the outer box is firmly sealed as a whole, and the structure needs to be destroyed before the outer box can be opened after buckling. The utility model has the advantages of no need for self-adhesive tape during packaging, convenient use, low cost, environmental protection, good firmness and reliable sealing.

[0010] The technical solution of the utility model is as follows:

[0064] Experimental data:

[0065] Due to the functional requirements of the transport express box, in order to ensure the buffering and transportation performance of the glue-free express box, the following performance tests are conducted on the glue-free express packaging box (Lo=284mm, Bo=292mm, Ho=117mm) in this case:

[0066] 1. Package free drop test experiment

[0067] 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, the cartons were actually transported and tested. 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 perform a drop test on the package. The test results of corner drop (observation direction: front), corner drop (observation direction: back), surface 1 (observation direction: front), surface 1 (observation direction: back), surface 2 (observation direction: front), surface 2 (observation direction: back), surface 3 (observation direction: front), surface 3 (observation direction: back), edge 1 (observation direction: front), edge 1 (observation direction: back), edge 2 (observation direction: front), edge 2 (observation direction: back), edge 3 (observation direction: front), edge 3 (observation direction: back) of the glue-free express packaging box in this case are shown in the following table:

[0068] Table 1 Free fall test results (this case)

[0069]

[0070] It can be seen that the drop test results of the glue-free express packaging box in this case showed no damage except for slight deformation of the corners and edges.

[0071] 2. Packaging compression test

[0072] 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:

[0073] 1. Constant pressure deformation test

[0074] Table 2 Deformation measurement effect at constant pressure (recorded 3 times)

[0075]

[0076] 2. Constant deformation test pressure resistance test

[0077] Table 3 Deformation resistance effect (recorded 3 times)

[0078]

[0079] 3. Maximum crushing force test

[0080] Table 4 Maximum crushing force test results (recorded 3 times)

[0081]

[0082] It can be seen that the deformation of the 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 compression resistance of the glue-free express packaging box in this case is better than that of the comparison sample.

[0083] 3. Summary: The results of the free drop test show that the glue-free express packaging box in this case has good cushioning performance and sealing reliability; the results of the packaging (empty box) compression test show that the glue-free express packaging box in this case has good sealing and compression protection.
