Technical Field
[0001] The utility model belongs to the technical field of packaging materials, and particularly relates to a zipper type carton. Background Art
[0002] Cartons are the most widely used packaging products, usually used as wrapping for goods or as outer protective layers for items. As an indispensable part of modern logistics, packaging cartons bear the important responsibilities of containing, protecting products and making them beautiful.
[0003] The style of conventional cartons can refer to CN307548329S. Because the upper and lower openings of traditional cartons are not fixed and closed, a large amount of tape is needed to seal the cartons during packaging. When using tape to seal traditional cartons, the workload for packaging personnel is relatively large, and packaging is time-consuming and laborious. After the carton is used, the tape will remain on the carton, which is not convenient for secondary recycling of the carton. Moreover, when it is used as garbage, the degradability of the tape is extremely poor, and it has a high pollution to the environment. Utility Model Content

[0016] ① Goods can be packaged without tape, saving time and effort: by setting up the easy-tear strip, the long cover plate is shielded above the two groups of storage boxes, and a part of the short cover plate is shielded and covered. At this time, the easy-tear strip is tightened under the strip-through gap, and the fixed head at the end of the easy-tear strip is pasted to the adhesive area after tightening; at this time, one end of the long cover plate is connected to the first short side plate and is limited, and the other end is pulled and limited by the easy-tear strip, so the long cover plate is fixed and cannot be opened, and one end of the short cover plate is limited by the second short side plate in the same way, and the other end is pressed under the long cover plate, so the short cover plate is also in an unopenable state. At this time, the long cover plate and the short cover plate completely cover the upper openings of the two groups of storage boxes, completing the tape-free packaging of the goods.
[0017] ② No tape impurities during recycling, and high degradability when discarded: Through the establishment of the easy-tear strip, when the purchaser of the goods needs to disassemble the carton described in the utility model, the tear plate is picked out from the half-cut hole, and then the tear plate is directly pulled upwards, under the action of the high-toughness easy-tear strip; the long cover plate is disconnected from the dotted hole into two separate cover plates. When the easy-tear strip is completely torn off, the remaining carton body does not have any plastic components and can be directly recycled. Even if it is discarded, the pure carton component will naturally degrade more smoothly, and will not cause greater pollution to the environment. It only needs to classify and handle the torn easy-tear strip separately. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] Brief description of the usage process:
[0039] When using, Figure 3 As shown, the carton is opened and the goods are placed in the storage box 29, and the goods are embedded in the embedded holes 7 on the storage plate 24 at the bottom of the storage box 29 (the size and shape of the embedded holes 7 match the size and shape of the goods. Since the size and shape of different goods are different, the size and shape of the embedded holes 7 are not limited). Then, the storage box 29 around the goods is filled with vibration-damping materials, or a foam pad is placed on the top of the goods to provide vibration-damping limit for the goods.
[0040] The third folding plate 4 is then bent so that the second short side plate 41 of the third folding plate 4 and the adjacent surrounding folding plate 22 are parallel to each other, and the short cover plate 42 is then shielded above the two groups of storage boxes 29; the second folding plate 3 is then bent so that the first short side plate 31 of the second folding plate 3 and the adjacent surrounding folding plate 22 are parallel to each other, and the long cover plate 32 is appropriately deflected so that the fixed head 53 end of the easy-tear strip 5 can pass through the strip-passing hole 43 and then through the strip-passing gap 27, and then the long cover plate 32 is further deflected so that the long cover plate 32 shields above the two groups of storage boxes 29 and shields and covers a part of the short cover plate 42, and at this time, the easy-tear strip 5 is tightened under the strip-passing gap 27, and after tightening, the fixed head 53 at the end of the easy-tear strip 5 is pasted to the adhesive area 28.
[0041] After the fixing head 53 is pasted on the adhesive area 28, one end of the long cover plate 32 is connected to the first short side plate 31 and is limited, and the other end is pulled and limited by the tear strip 5, so the long cover plate 32 is fixed and cannot be opened, and one end of the short cover plate 42 is similarly limited by the second short side plate 41, and the other end is pressed under the long cover plate 32, so the short cover plate 42 is also in an unopenable state. At this time, the long cover plate and the short cover plate 42 completely cover the upper openings of the two groups of storage boxes 29, completing the tape-free packaging of the goods.
[0042] When the buyer of the goods needs to disassemble the carton described in the utility model, the tear plate 51 is pulled out from the half-cut hole 33, and then the tear plate 51 is pulled directly upward like a zipper. Under the action of the high-toughness tear strip 5 (the tear strip 5 is a high-toughness plastic film, and its material is consistent with the material of the tear strip 5 used in the existing zipper-type carton, so its material composition is not limited here); the long cover plate 32 is disconnected from the dotted hole 52 into two separate cover plates. When the tear strip 5 is completely torn off, the tear strip 5 cancels the deflection limit on the long cover plate 32. At this time, the long cover plate 32 can be deflected open to reveal the storage box 29, and then the goods can be taken out from the embedded hole 7.
[0043] This specific embodiment is merely an explanation of the present invention and is not a limitation of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed, but such modifications are protected by patent law as long as they are within the scope of the claims of the present invention.
