Abstract
Description
Technical Field
[0001] This utility model relates to the field of cardboard box technology, and in particular to a cardboard box that is easy to seal. Background Technology
[0002] Easy-to-seal cardboard boxes are a category of cardboard boxes that have undergone in-depth optimization in structural design and functional characteristics, aiming to achieve more convenient and efficient sealing. From a structural design perspective, they break through the relatively fixed and single architectural pattern of traditional cardboard boxes.
[0003] Currently, the internal structure and size of packaged cardboard boxes are usually fixed. This fixed internal structure provides stable support and protection for the goods, facilitating standardized and large-scale production. The fixed structural design also makes it easier to develop uniform production processes and molds, improving production efficiency and reducing production costs.
[0004] While the fixed internal structure and size of cardboard boxes facilitate standardized production, their limited spatial flexibility makes them unsuitable for packaging items of varying sizes and shapes. If the item's dimensions don't match the box's internal structure, it leads to wasted space and increased packaging and transportation costs. Therefore, this paper proposes a cardboard box designed for easy sealing to address these issues. Utility Model Content

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0035] Reference Figure 1 , Figure 2 and Figure 3An embodiment of this utility model is provided: a carton that is easy to seal, including a carton body 1, multiple movable plates 18 and multiple movable plates 19. Multiple sliding plates 10 are fixedly connected to the inner side of the carton body 1. A partition assembly is provided on the inner side of the multiple sliding plates 10. A protective assembly is provided on the outer side of the carton body 1. Two unsealing components are provided on the outer sides of both ends of the carton body 1.
[0036] The partition assembly includes multiple protective flexible panels 6, each end of which is slidably connected to the inner side of multiple sliding plates 10. A support rod 5 is installed inside the housing 1, with sliding grooves 7 formed on the inner sides of each support rod 5. The other ends of the multiple protective flexible panels 6 are slidably connected to the inner sides of the sliding grooves 7. By sliding the multiple protective flexible panels 6 to the positions of the sliding plates 10, the interior of the housing 1 is divided into multiple independent spaces of different sizes. The partition assembly also includes two locking blocks 4, each located at one end of the support rod 5. Each locking block 4 has a locking groove 9 on its inner side, and the outer sides of the multiple protective flexible panels 6 and the support rod 5 are locked into the inner sides of the two locking grooves 9. The two locking blocks 4 are respectively locked into the two ends of the support rod 5, with the locking grooves 9 on the inner sides of the locking blocks 4 used to lock the protective flexible panels 6 and the two ends of the support rod 5. This locking method ensures that the protective flexible panels 6 and the support rod 5 remain stable after being adjusted in position, and will not easily shift due to vibration or collision during transportation, thus ensuring the stability of the partition structure.
[0037] Reference Figure 1 , Figure 2 , Figure 5 and Figure 6 The unpacking assembly includes two adhesive layers 14, which are fixedly connected to the outer ends of two movable plates 19. One adhesive layer 14 has a hook-faced layer 15 fixedly connected to its outer side, and the other adhesive layer 14 has a textured layer 16 fixedly connected to its outer side. Multiple textured layers 16 are respectively positioned on the outer sides of multiple hook-faced layers 15. When sealing the carton, simply press the movable plates 19 with the hook-faced layers 15 and textured layers 16 together. The small hooks on the hook-faced layers 15 will embed into the fibers of the textured layers 16, achieving a tight seal and completing the carton sealing. When unpacking, simply pull the movable plates 19 apart to separate the hook-faced layers 15 from the textured layers 16, and the carton can be easily opened. This method is simple to operate, requires no additional tools, and can be reused multiple times.
[0038] Reference Figure 1 and Figure 2The protective components include two impact-resistant layers 2, both fixedly connected to the outside of the box body 1. Multiple movable panels 19 are also fixedly connected to their outer sides with protective soft rubber layers 3. The impact-resistant layers 2 on the outside of the box body 1 and the protective soft rubber layers 3 on the outer sides of the movable panels 19 effectively buffer external impacts, reducing damage to the contents of the box. During transportation and handling, even if the carton is accidentally impacted, it can protect the safety of the items to the greatest extent, making it suitable for packaging fragile items, precision instruments, etc.
[0039] Reference Figure 2 , Figure 3 and Figure 4 The inner sides of the box body 1, multiple movable panels 18, and multiple movable panels 19 are all equipped with a polylactic acid layer 11, corrugated paper 12, foam board 13, and a butyl rubber layer 17. The butyl rubber layer 17 is placed on the outer layer of the box body 1, multiple movable panels 18, and multiple movable panels 19. The butyl rubber layer 17 has good moisture-proof and waterproof properties, effectively blocking the intrusion of external moisture and protecting the items inside the box from moisture damage. The polylactic acid layer 11, corrugated paper 12, and foam board 13 are all placed inside the butyl rubber layer 17. The corrugated paper 12 enhances the box's compression resistance, while the foam board 13 acts as a shock absorber when subjected to vibration, ensuring that the items are not damaged during transportation. Fiberboard 8 is installed inside the multiple protective soft panels 6. The fiberboard 8 enhances the strength and toughness of the protective soft panels 6, enabling them to withstand a certain amount of pressure. Even when heavy items are placed on them, the partitions are not easily deformed or damaged, further improving the protection of the items. Multiple movable plates 18 and multiple movable plates 2 19 are respectively arranged on the outer sides of both ends of the carton 1. Multiple movable plates 18 are arranged on the sides of the two locking blocks 4, and multiple movable plates 2 19 are respectively arranged on the outer sides of multiple movable plates 18. The reasonable layout of movable plates 18 and movable plates 2 19, as well as the cooperation of the unpacking components, enable the carton to be tightly closed during sealing, effectively preventing items from scattering or being lost during transportation.
[0040] Working principle: First, rotate the movable plate 18 at one end inward, then rotate the two movable plates 19 at this end inward, and then attach the two rough surface layers 16 at this end to the sides of the other two hook surface layers 15 respectively.
[0041] Then, when multiple small items of different types need to be placed, the protective soft panel 6 can be slid to the inside of the multiple sliding plates 10 on the inner side of the box 1 to separate independent spaces, preventing items from colliding with each other. The locking blocks 4 and locking slots 9 ensure that the protective soft panel 6 and support rod 5 will not easily move. The fiberboard 8 installed on the inner side of the multiple protective soft panels 6 enhances the strength and toughness of the protective soft panels 6, enabling them to withstand a certain amount of pressure while fulfilling their separating function, thus better protecting the items inside the box. When heavier items are placed in the spaces separated by the protective soft panels 6, the fiberboard 8 ensures that the protective soft panels 6 will not easily deform or be damaged.
[0042] When the object is placed, the two movable plates 18 and 19 on the other end are operated in the same way. First, the two movable plates 18 are folded, and then the two movable plates 19 are folded. The two rough outer layers 16 of the movable plates 19 are then pasted to the sides of the other two hook layers 15 to achieve the sealing of the carton.
[0043] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
