Description

Technical Field

[0001] This utility model relates to the field of packaging carton technology, specifically to a packaging carton with a high-barrier nano-coating. Background Technology

[0002] High-barrier nano-coated packaging cartons are an innovative packaging material that combines nanotechnology with high barrier performance. By forming a nano-level protective layer on the surface of the cartons, their barrier properties, mechanical strength, and environmental performance are significantly improved. They are widely used in food, pharmaceuticals, and electronic products. With their excellent barrier properties, environmental friendliness, and functionality, they are becoming an innovative direction in the packaging industry. As technology iterates and market demands upgrade, their application scenarios will be further expanded, contributing to green packaging and sustainable development.

[0003] The packaging carton disclosed in the authorization announcement number CN208593592U includes a square paper box body. The opening of the paper box body is provided with a box cover. The box cover includes a front box cover provided on the front side wall of the paper box body and a rear box cover provided on the rear side wall of the paper box body. A bottom protective plate is glued and fixed to the bottom of the paper box body. A square column-shaped protective body is provided on the bottom protective plate and installed on the paper box body. The front side wall of the square column-shaped protective body is provided with two front vertical insertion slots. The rear side wall of the square column-shaped protective body is provided with two rear vertical insertion slots that cooperate with the front vertical insertion slots. A partition plate is detachably inserted between the front vertical insertion slots and the rear vertical insertion slots.

[0004] Although it has high structural strength, it can protect the products inside the carton and can partition the internal space of the carton as needed.

[0005] The partitioned design in the above-mentioned technology fails to effectively solve the problem of limiting and fixing the internal items after partitioning. When the size of the load is smaller than the internal cavity of the partition, the items are prone to displacement and shaking during the movement of the box due to the lack of effective constraints. This movement state can not only cause packaging damage due to mutual collision, but may also cause surface damage or structural deformation of the packaged items due to continuous impact. Utility Model Content

[0006] The purpose of this utility model is to provide a packaging carton with a high-barrier nano-coating to solve the problem mentioned in the background art that when the size of the load is smaller than the partition cavity, the item is prone to displacement and shaking during handling vibration or logistics flow due to the lack of effective restraint during the movement of the carton, resulting in damage to the item.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a packaging carton with a high-barrier nano-coating, comprising a carton body with a high-barrier nano-coating on its inner wall, a square column-shaped protective body fixedly connected inside the carton body, slots on both sides of the middle of the square column-shaped protective body, insert plates slidably connected inside the two slots, and abutment plates provided at the upper middle of the middle of the two end faces of the insert plates, the abutment plates being elastic elements, compression columns fixedly connected at both ends of the lower end face of the slots, and a sliding assembly provided at the lower end of the insert plate, the sliding assembly being used to drive the abutment plates to arch or flatten.

[0008] Preferably, a buffer spring seat is fixedly connected to the upper end of the extrusion column, and a rubber head is fixedly connected to the upper end of the buffer spring seat.

[0009] Preferably, the sliding assembly includes a sliding plate slidably connected to the lower end of the insert plate, the lower end of the insert plate has an opening groove, the sliding plate is slidably connected to the insert plate through the opening groove, the upper end of the abutment plate is fixedly connected to the insert plate, and the lower end of the abutment plate is fixedly connected to the sliding plate.

[0010] Preferably, both ends of the opening groove are circular and adapted to the two ends of the slide plate.

[0011] Preferably, a fixing ring is fixedly connected to both sides of the lower end of the opening groove, and a tension spring is fixedly connected to the outer side of the upper end of each of the two fixing rings. The upper end of the tension spring is fixedly connected to the slide plate, and the tension spring is sleeved on the outside of the extrusion column and the buffer spring seat.

[0012] Preferably, a plurality of contact strips are fixedly connected at even intervals on the side of the abutment plate away from the insert plate, and the contact strips are made of rubber material.

[0013] Preferably, the upper end face of the insert plate has an opening in the middle, and a handle is fixedly connected to the upper end of the opening. Placement slots are provided on both sides of the square column-shaped protective body.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This cardboard box utilizes a synergistic design of an abutment plate and a sliding assembly to securely hold items within its interior areas. When the insert plate is inserted into the slot, the compression column drives the sliding plate to shift, forcing the elastic abutment plate to undergo controllable deformation and arch outwards, contacting the items and forming a three-dimensional support structure that matches their shape. This adaptive adjustment mechanism effectively limits the placement of items inside the box, eliminating the risk of swaying caused by variations in item size in traditional cardboard boxes. This significantly improves stability during transport, making it particularly suitable for protecting irregularly shaped or precision items.

[0016] Based on the limiting function, this carton incorporates a multi-level cushioning structure: the cushioning spring seat absorbs the vibration energy during transportation through elastic deformation, the rubber contact strip uses flexible material to optimize the pressure distribution on the contact surface, and when the contact plate exerts a limiting effect, the cushioning spring seat can dynamically adjust the squeezing force to ensure sufficient fixing strength while avoiding surface damage caused by rigid contact. While ensuring the stability of the item's position, it builds a dual barrier against impact and vibration, making it suitable for long-distance transportation of fragile and high-value products.

[0027] Example 1

[0028] Please see Figures 1 to 6 An embodiment of this utility model provides: a packaging carton with a high-barrier nano-coating, including a carton body 1 with a high-barrier nano-coating on the inner wall, a square column-shaped protective body 3 fixedly connected inside the carton body 1, slots 14 are provided on both sides of the middle of the square column-shaped protective body 3, insert plates 4 are slidably connected inside the two slots 14, and abutment plates 5 are provided at the upper end of the middle of the two end faces of the insert plates 4. The abutment plates 5 are elastic elements, and extrusion columns 10 are fixedly connected to both ends of the lower end face of the slots 14. A sliding component is provided at the lower end of the insert plate 4. The sliding component is used to drive the abutment plates 5 to arch or flatten. An opening is provided at the middle of the upper end face of the insert plate 4. A handle 7 is fixedly connected at the middle of the upper end of the opening. Placement slots 2 are provided on both sides of the square column-shaped protective body 3.

[0029] This packaging carton features an innovative structural design. The inner wall of the carton is coated with a high-barrier nano-coating, which effectively blocks the penetration of moisture, oxygen, and odors, significantly improving the protection of the contents. The core of the carton is equipped with a square column-shaped protective body 3, with slots 14 on both sides and sliding inserts 4 forming an adaptive limiting system. When the insert 4 is inserted vertically along the slot 14, the bottom squeezing column 10 drives the internal sliding component through mechanical linkage, causing the elastic contact plate 5 to automatically arch outward to form a three-dimensional support structure. The rubber contact strips 13 on its surface can closely fit items of different sizes, achieving precise limiting and fixing. The handle 7 on the top of the insert 4 is easy to operate, and the placement slots 2 on both sides of the square column-shaped protective body 3 provide additional storage space. This modular design, through the synergistic effect of mechanical deformation and elastic elements, ensures the stability of the items during transportation and creates a double protective barrier through the high-barrier coating. It is particularly suitable for packaging scenarios that require comprehensive protection, such as precision instruments and fragile items.

[0030] A buffer spring seat 8 is fixedly connected to the upper end of the extrusion column 10. A rubber head is fixedly connected to the upper end of the buffer spring seat 8. The sliding assembly includes a slide plate 12 that is slidably connected to the lower end of the insert plate 4. An opening groove 6 is provided at the lower end of the insert plate 4. The slide plate 12 is slidably connected to the insert plate 4 through the opening groove 6. The upper end of the abutment plate 5 is fixedly connected to the insert plate 4. The lower end of the abutment plate 5 is fixedly connected to the slide plate 12. Both ends of the opening groove 6 are round and are adapted to the two ends of the slide plate 12. Fixing rings 9 are fixedly connected to both sides of the lower end of the opening groove 6. Tension springs 11 are fixedly connected to the outer side of the upper end of the two fixing rings 9. The upper end of the tension springs 11 is fixedly connected to the slide plate 12. The tension springs 11 are sleeved on the outside of the extrusion column 10 and the buffer spring seat 8. Multiple contact strips 13 are evenly spaced and fixedly connected to the side end face of the abutment plate 5 away from the insert plate 4. The contact strips 13 are made of rubber material.

[0031] The packaging carton achieves adaptive fixation through the collaboration of multiple components: when the insert plate 4 is vertically inserted into the slot 14, the bottom compression column 10 establishes a mechanical transmission with the slide plate 12 through the buffer spring seat 8. As the insertion continues, the thrust of the compression column 10 pushes the slide plate 12 to move directionally along the opening slot 6; at this time, the arc-shaped contact plate 5 connecting the slide plate 12 and the insert plate 4 deforms due to the displacement difference between the upper and lower fixed points, and the contact plate 5 arches outward. Its arc structure unfolds outward to form a three-dimensional support frame, and the rubber contact strips 13 on the surface are fully attached to the surface of the item through the flexible material. When the insert plate 4 is fully in place, the buffer spring seat 8 can... Appropriate deformation maintains a stable preload, keeping the contact plate 5 in a moderately deformed state. At the same time, the secondary shock absorption system composed of the buffer components can effectively absorb the impact of transportation. The tenon structure between the slot 14 and the insert plate 4 provides multi-directional constraint protection. This design allows the limiting mechanism to automatically adjust the support shape according to the size of the item. Through the displacement transmission of mechanical parts and the deformation of elastic elements, the precise positioning and reliable fixing of items of different specifications in the carton can be achieved. When the insert plate 4 is pulled out, the slide plate 12 moves downward through the action of the tension spring 11, completing the flattening of the contact plate 5. Finally, the insert plate 4 can be placed into the placement slot 2.

[0032] Work steps

[0033] In this embodiment, the following steps are taken when using the cardboard box: First, fully unfold the cardboard box body 1. Depending on the characteristics of the item, place it directly in the bottom of the box, or hold the upper handle 7 of the insert plate 4 and vertically insert the insert plate 4 into the slot 14 in the middle of the protective body. During insertion, the pressing post 10 at the bottom of the slot 14 forms dynamic contact with the sliding plate 12 inside the insert plate 4 through the buffer spring seat 8. As the insert plate 4 continues to penetrate deeper, the axial thrust of the pressing post 10 forces the sliding plate 12 to slide upward along the opening slot 6, thereby causing the arc-shaped contact plate 5 to undergo elastic deformation. Its arc structure arches outward, making... The rubber contact strips 13 of the surface array gradually conform to the outline of the item; when the insert plate 4 is pressed down to the limit position, the buffer spring seat 8 can deform, and the pre-tightening force transmitted by the fixing ring 9 is controlled within a safe range through the rubber head, so that the contact plate 5 forms a moderate pressure on the item, which ensures transportation stability and avoids excessive squeezing force. Finally, the sealing operation is completed, and the top cover of the carton body 1 covers the insert plate 4 to prevent the insert plate 4 from popping out. At this time, the high barrier nano-coating on the inner wall of the carton works together with the external limiting mechanism to build a dual protection system that combines environmental protection and physical fixation.

[0034] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
