Description

Express carton that can be used repeatedly three times and processing method

Technical Field

The invention relates to an express paper box which can be repeatedly used three times and a processing method thereof, belonging to the technical field of logistics transportation packaging.

Background Art

At present, compared with wooden boxes, express corrugated boxes have the advantages of lightness, easy processing and low cost during transportation. These advantages will gradually replace wooden boxes with corrugated boxes. Corrugated boxes are widely used in the express industry. The general process of express delivery from the postal company to the hands of consumers is: the sender fills in the delivery information at the express company. The express company has specific requirements for the packaging of items. Each edge of the corrugated box must be sealed with tape, and the body plate is sealed with tape cross. Then the express order is pasted on the outer packaging. After the express company picks up the goods, the information can be checked online. Before the goods enter the warehouse, they need to be inspected and processed, and then the warehouse location is allocated, and the express parcels are sorted. The transportation tools include railway transportation, road transportation, aircraft transportation, ship transportation, etc. After the package arrives at the destination, the courier generally marks it in a conspicuous place with a signature pen, and sorts it according to the destination manually. After the consignee checks and confirms the receipt, he confirms it with the return slip to the logistics distribution center. Generally, the express parcel is delivered directly to the destination community or residence. If the community has logistics temporary storage boxes and other tools for storing express parcels, they are stored. If not, take it back to the express delivery point and wait for the recipient to pick it up. After receiving the express, the recipient usually checks the outer packaging first. If there is no obvious damage or scratches, open the box for inspection, take out your own goods, and throw the outer packaging directly into the trash can. If the packaging is damaged or scratched, you need to contact the seller and the courier online or by other means, and the three parties will negotiate and jointly handle the corresponding loss compensation matters.

With the rapid development of the express delivery industry in the Internet era, the consumption of express delivery packaging continues to grow, but there are many problems in my country's transportation packaging field: such as the difficulty in recycling packaging materials and the low recycling rate; the short life cycle of express delivery packaging, which is out of circulation after one use; and the large-scale use of non-degradable materials such as plastic tape, which has led to serious environmental pollution and waste of resources. These problems cannot meet the social needs of energy conservation and emission reduction proposed by economic development, resulting in excessive pressure on environmental protection costs and urgent need to control production energy consumption.

In view of the current problems in the express delivery industry such as excessive use of tape, which pollutes the environment; tape is withdrawn from circulation after being used once, which wastes resources; and it is difficult to be discovered if it is stolen during circulation, there is an urgent need for a reusable express carton and processing method.

The method of using the present invention:

Figures 1 to 21 show the entire life cycle of the carton, which includes five stages: 1. Carton blank forming stage: completed by the corrugated carton manufacturer. 2. First use stage: completed by the consumer. 3. Second use stage: completed by the consumer. 4. Third use stage: completed by the consumer. 5. Carton reuse stage: completed by the consumer.

Stage 1: Box blank forming stage:

Figure 1 shows a plan view of a box blank. The packaging box blank is made of a cardboard with a length of L and a width of W by cutting and removing material.

Figure 2 shows the folding process of the cover plate flaps. First, cover plate convex flap piece 14 and cover plate concave flap piece 15 connected to cover plate 1 6 are folded inwards; second, cover plate hole flap piece 16 connected to cover plate 2 7 is folded inwards, and cover plate convex flap piece 2 37 and cover plate concave flap piece 2 38 connected to cover plate 3 8 are folded inwards; third, cover plate hole flap piece 2 39 connected to cover plate 4 9 is folded inwards.

Figure 3 shows the process of bonding the flaps of the carton. First, glue is applied to the surfaces of the manufacturer's joint 1, the cover plate concave flap piece 15 connected to the cover plate 1 6, the cover plate concave flap piece 2 38 connected to the cover plate 3 8, the cover plate hole flap piece 16 connected to the cover plate 2 7, and the cover plate hole flap piece 2 39 connected to the cover plate 4 9; secondly, the longitudinal pressure line 2 32 between the side body plate 1 2 and the side body plate 2 3, and the longitudinal pressure line 4 33 between the side body plate 3 4 and the side body plate 4 5 are folded in half, so that the adjacent cover plate concave flap piece 15 and the cover plate hole flap piece 16 are bonded to each other, and the cover plate concave flap piece 2 38 and the cover plate hole flap piece 2 39 are bonded to each other; at the same time, the manufacturer's joint 1 is bonded to the body plate 4 5 to form the carton into the factory state.

At this point, the carton is formed into the factory state shown in Figure 3.

Phase 2: Initial use:

First, the longitudinal pressure line 2 32 and the longitudinal pressure line 4 33 are pushed toward the center of the carton at the same time, so that the carton is formed from the flat factory state of FIG. 3 to the semi-folded state shown in FIG. 4. Continuing to push the longitudinal pressure line 2 32 and the longitudinal pressure line 4 33, the two cover plate meshing points 35 on the cover plate 1 6 and the cover plate 3 8 are overlapped, and finally the box cover is completely closed into a regular rectangle. The carton after the box cover is closed is shown in FIG. 5.

Based on Figure 5, the carton is turned over so that the bottom part of the box faces upward, and the state is shown in Figure 6. At this time, the contents 1 24 are loaded into the box. Then, the bottom plate 2 11 and the bottom plate 4 13 are folded, and then the bottom plate 1 10 and the bottom plate 3 12 are folded into the state shown in Figure 7. There is a prefabricated adhesive tape 26 at the inner edge of the bottom plate 10. At the same time, the bottom plate 10 and the bottom plate 3 12 have overlapping parts for bonding after being folded. Tearing off the surface paper of the prefabricated adhesive tape 26 can make the bottom plate 10 and the bottom plate 3 12 firmly bonded. The bottom of the box is sealed as shown in Figure 8.

The carton in the state shown in FIG8 will enter the logistics circulation link and reach the hands of the recipient. If the recipient wants to open the carton to take out the contents, he only needs to turn the carton cover plate 1 6, cover plate 2 7, cover plate 3 8 and cover plate 4 9 upwards (as shown in FIG9). Cover plate 2 7 and cover plate 4 9 are respectively designed with cover plate cut line 1 23 and cover plate cut line 2 41, and cover plate 2 7 and cover plate 4 9 can be torn apart along cover plate cut line 1 23 and cover plate cut line 2 41 respectively. This can separate cover plate 2 7 from cover plate 1 6, and cover plate 4 9 from cover plate 3 8, so that the four box covers are in an openable state (as shown in FIG10). At this time, the cover plate hole flap piece 1 16 originally connected to cover plate 2 7 and the cover plate hole flap piece 2 39 connected to cover plate 4 9 will remain on cover plate 1 6 and cover plate 3 8 to become the remaining cover plate hole flap piece 27 (as shown in FIG11). Finally, cover plate 1 6, cover plate 2 7, cover plate 3 8 and cover plate 4 9 are folded outwards respectively, and the content 1 24 can be taken out from the box.

At this point, the carton has completed its first use.

Phase 3: Secondary use phase:

As shown in Figure 11, after the first content 24 is taken out of the carton, new content 25 can be loaded, thereby entering the secondary use stage of the carton. Figure 12 shows the state of loading the new content 25.

Figures 13 to 15 show the secondary box sealing process. After the contents 25 are loaded into the box, first, cover plate 2 7 and cover plate 4 9 are folded inwardly; then, cover plate convex flap piece 1 14 and cover plate convex flap piece 2 37 folded inwardly on cover plate 1 6 and cover plate 3 8 are respectively flattened outwardly; at the same time, cover plate concave flap piece 1 15 and cover plate concave flap piece 2 38 folded inwardly on cover plate 1 6 and cover plate 3 8 are flattened outwardly, so that cover plate convex flap piece 1 14, cover plate concave flap piece 1 15 and cover plate 1 6 are on the same plane, and cover plate convex flap piece 2 37 and cover plate concave flap piece 2 38 are on the same plane with cover plate 3 8. The state at this time is shown in Figure 13.

Next, cover plate 16 and cover plate 38 are folded inwardly of the box, so that the two cover plate meshing points 35 on cover plate 16 and cover plate 38 overlap each other, and the box cover is initially sealed; then, cover plate convex flap piece 14 and cover plate convex flap piece 237 on cover plate 16 and cover plate 38 are placed on the remaining cover plate hole flap piece 27; then, the anti-theft flap piece 17 connected to the cover plate convex flap piece 14 is folded inwardly by 90°; then, the insertion flap piece side ears 19 connected to both sides of the anti-theft flap piece 17 are folded inwardly by 90°; finally, the folded anti-theft flap piece 17 and the insertion flap piece side ears 19 are inserted into the flap piece insertion hole 18, and the installation of the anti-theft flap piece 240 is similar to that of the anti-theft flap piece 17, which will not be described again. The state at this time is shown in Figure 14.

After the insertion flap side ears 19 of the anti-theft flap 17 and the anti-theft flap 2 40 are completely inserted into the corresponding flap insertion holes 18 and 42, the box cover is in the state shown in Figure 15. At this time, the cover plate convex flap 14 and the cover plate convex flap 2 37 will be tightly locked with the corresponding remaining cover plate hole flap 27, and the cover plate 1 6 and the cover plate 3 8 will be tightly engaged, thereby completing the resealing of the box cover.

After the anti-theft flap 17 and the inserted flap side ears 19 are inserted into the flap insertion hole 18, the inserted flap side ears 19 will automatically flatten so that the anti-theft flap 17 and the inserted flap side ears 19 on both sides are on the same plane. At this time, the structure cannot be pulled out from the flap insertion hole 18 without being destroyed, thereby forming an anti-theft open state together with the flap insertion hole 18.

The carton in the state shown in FIG15 will enter the logistics circulation link and reach the recipient. If the recipient wants to open the carton to take out the contents, he only needs to tear the anti-theft flap piece 17 and the anti-theft flap piece 2 40 from the cover plate convex flap piece 14 and the cover plate convex flap piece 2 37 along the anti-theft flap piece cut line 36. After the anti-theft flap piece 17 and the anti-theft flap piece 2 40 are torn off, the original cover plate convex flap piece 14 and the cover plate convex flap piece 2 37 will only have a triangular area left and become the residual cover plate convex flap piece 28. At this time, the state of the carton is shown in FIG17. Next, cover plate 1 6 and cover plate 3 8 are folded outward from the box first, and then cover plate 2 7 and cover plate 4 9 are folded outward from the box to take out the contents 25, as shown in FIG18.

At this point, the carton has completed its second use.

Stage 4, three-time use stage:

As shown in Figure 18, after removing the second content 25 from the carton, new content 3 29 can be loaded, thus entering the third use stage of the carton. Figure 19 shows the state of loading the third content 29, at which time the carton is used in the same way as a general standard corrugated slotted box.

After the contents 3 29 are loaded into the box, the cover plates 2 7, 4 9, 1 6 and 3 8 are folded inwards in sequence to form a box cover; finally, the box is sealed longitudinally with adhesive tape 30, as shown in FIG20. The box in the state shown in FIG20 will enter the logistics circulation link and reach the recipient.

At this point, the carton has completed its third use.

Stage 5: Carton Recycling Stage:

After three times of use, the carton has completed its mission as a package. It can then be recycled as waste paper to become a raw material for new green packaging materials; it can also be reused by consumers. After the third use, the carton only needs to remove the bottom plate 10 and the side plate 2 to become a storage box for books and other daily necessities 31 as shown in FIG. 21.

With environmental protection as the design concept, we designed a green and environmentally friendly express carton that has efficient assembly, can be used multiple times, and can be transformed from old objects. It can be reused three times, and has passed packaging performance tests and actual transportation tests to prove that it can be put into market use.
