[0002] The corrugated paperboard has a special structure, 60-70% of the volume of the paperboard structure is empty, so the corrugated paperboard box has good shock absorption performance, and can avoid the packaged articles from being impacted and shocked. In addition, the corrugated paperboard box is light, the corrugated paperboard is a hollow structure, and a large rigid box body is formed by using the least material, so the corrugated paperboard box is light and firm, and compared with a wooden box of the same volume, the corrugated paperboard box is only 10-30% of the weight of the wooden box.

DETAILED DESCRIPTION

[0036] In order to further understand the inventive content, characteristics and effects of the present application, the following embodiments are exemplified and described in detail as follows with reference to the accompanying drawings.

[0037] The structure of the present application will be described in detail below with reference to the accompanying drawings.

[0038] Reference is made to Figures 1-4 ​The embodiment of the present application provides a damp-proof paperboard box for sea transportation, which comprises an outer box body 1, an inner box body 2 and an intermediate piece 3, the inner box body 2 is located inside the outer box body 1, the intermediate piece 3 is located between the outer box body 1 and the inner box body 2, the outer box body 1 comprises an outer bottom wall 11 and a plurality of outer side walls 12, the upper side of the outer bottom wall 11 is provided with a buffer piece 4; the inner box body 2 is detachably arranged inside the outer box body 1, the inner box body 2 comprises an inner bottom wall 21 and a plurality of inner side walls 22, the lower surface of the inner bottom wall 21 is attached to the buffer piece 4, and the inner side walls 22 and the outer side walls 12 have a gap; the intermediate piece 3 is arranged in the gap, and at least one of the outer side walls 12 and the intermediate piece 3 is arranged as a water-proof plate-shaped piece.

[0039] For example, the material of the outer box body 1 can be plastic or metal, or paperboard, when the outer box body 1 is plastic or metal, the damp-proof effect can be achieved (in the case that there is no gap between the outer bottom wall 11 and the outer side wall 12). The material of the inner box body 2 is paperboard, in use, goods can be placed in the inner box body 2, the inner box body 2 can be taken out of the outer box body 1 for unloading and loading, and the lightness and buffering characteristics of the paperboard box can be fully utilized. At least one of the outer side wall 12 and the intermediate piece 3 is arranged as a water-proof plate-shaped piece, which can prevent the humid air outside from entering the inner box body 2, for example, the intermediate piece 3 is arranged as a bubble pad.

[0040] In use, the inner box body 2 can be used separately from the outer box body 1, or can be used in combination. The outer box body 1 is stationary at a storage location, the inner box body 2 is taken out of the outer box body 1, transported to a loading location, loaded, then transported to the storage location, and the loaded inner box body 2 is placed into the outer box body 1. Since the inner box body 2 is a paperboard box, the lightness and buffering characteristics of the paperboard box can be fully utilized in this process, which is convenient for loading and transportation. After the inner box body 2 is placed into the outer box body 1, on the one hand, the damp-proof effect can be achieved, and on the other hand, the inner box body 2 can be protected.

[0041] It should be noted that through the above arrangement, the following more flexible use modes are also provided:

[0042] Flexible use mode one: the outer box body 1 is used alone, goods are placed into the outer box body 1, at this time, the outer box body 1 can be used as a common box, and the outer box body 1 can be arranged as a paperboard box, or a plastic box or a metal box.

[0043] Flexible use mode two: the outer box body 1 and the intermediate piece 3 are used in combination, goods are placed into the outer box body 1, and the intermediate piece 3 has a buffering effect on the goods. If the goods themselves have water vapor, the intermediate piece 3 (for example, a bubble pad) can prevent the water vapor from entering the outer box body 1.

[0044] Flexible use mode three: the inner box body 2 is used alone, at this time, it is equivalent to a common paperboard box.

[0045] Flexible use mode four: the inner box 2 and the intermediate piece 3 are used in cooperation, the intermediate piece 3 is arranged outside the inner side wall 22, and the intermediate piece 3 can play a buffering and moisture-proof effect during use.

[0046] Referring to Figure 5 and Figure 7 , the intermediate piece 3 is provided as a hollow plate-shaped piece capable of spraying air when being extruded and capable of resetting and inhaling air after the extrusion is released; the hollow plate-shaped piece has an air inlet 31 and an air outlet 32, and the air outlet 32 is located in the gap.

[0047] During sea transportation, the goods are often in a shaking state, and the inner box 2 and the outer box 1 do not swing synchronously, so that the outer side wall 12 and the inner side wall 22 extrude the hollow plate-shaped piece, so that the air in the hollow plate-shaped piece is extruded into the gap and contacts the inner box 2 and the outer box 1, thereby drying the inner box 2 and the outer box 1 (only the inner side wall 22 can also be dried, as long as the air outlet 32 is directed to the inner side wall 22), and the hollow plate-shaped piece can reset and inhale air after the extrusion is released. During sea transportation, the hollow plate-shaped piece irregularly (not regularly and quantitatively) inhales and sprays air, which not only isolates humid air, but also realizes drying of the inner box 2 and / or the outer box 1 in a powerless manner.

[0048] Referring to Figure 3 , a plurality of through holes 23 are arranged on the side wall of the inner box 2, and the air outlet 32 is at least partially aligned with the through holes 23. Through the arrangement, the dried air can be extruded into the inner box 2, thereby realizing air permeation and drying and heat dissipation of the goods in the inner box 2.

[0049] Referring to Figure 2 , Figure 5 and Figure 7 , the side wall of the outer box 1 is connected with an air inlet pipe 5 in a penetrating manner, the air inlet pipe 5 is internally provided with a drying piece (for example, a desiccant), two ends of the air inlet pipe 5 are respectively located inside and outside the outer box 1, the air inlet 31 is in communication with the air inlet pipe 5, and one-way valves are arranged on the air inlet 31 and the air outlet 32, so that the air inlet 31 can only inhale air, and the air outlet 32 can only exhale air.

[0050] Through the arrangement, when the air outside is humid, the drying piece can filter the air to improve the drying degree of the air, thereby ensuring the drying effect.

[0051] Referring to Figure 5The hollow plate-shaped member comprises a first layer plate 33, a second layer plate 34, an elastic reset member 35, and an air bag 36; the first layer plate 33 and the second layer plate 34 are elastically connected through the elastic reset member 35; the air bag 36 is located between the first layer plate 33 and the second layer plate 34, and the two sides of the air bag 36 are respectively bonded to the first layer plate 33 and the second layer plate 34; the air inlet 31 and the air outlet 32 are both arranged on the air bag 36.

[0052] Through the arrangement, when the inner box 2 and the outer box 1 shake, the gap on one side can be reduced, the first layer plate 33 and the second layer plate 34 can be squeezed, the first layer plate 33 and the second layer plate 34 can be moved close to each other, the air in the air bag 36 can be sprayed out of the air outlet 32, and at the same time, the elastic reset member 35 (for example, a spring) can be squeezed, when the gap increases, the elastic reset member 35 drives the first layer plate 33 and the second layer plate 34 to move away from each other, so as to pull the air bag 36 to the two sides and inhale air.

[0053] In addition, the elastic member and the air bag 36 both have a buffering function, and can protect the inner box 2.

[0054] For example, referring to Figure 6 The first layer plate 33 is close to the inner box 2, and the second layer plate 34 is close to the outer box 1. The first layer plate 33 is provided with an air outlet hole 331, the air outlet hole 331 is aligned with the air outlet 32, and the side of the first layer plate 33 away from the air bag 36 is provided with a gas flow channel 37 in communication with the air outlet hole 331. Through the arrangement, the gas discharged from the air outlet 32 can flow in the gas flow channel 37, and the inner box 2 can be conveniently dried.

[0055] In addition, the paperboard box also has a disadvantage that when the paperboard box is placed in the storage place or taken out from the storage place, the paperboard box is easily damaged when the paperboard box is pushed or pulled. In order to solve the problem, the following arrangement is made:

[0056] For example, referring to Figure 1 and Figure 4 One of the outer side walls 12 is a rotating wall 13, the lower side of the rotating wall 13 is rotatably connected to two adjacent outer side walls 12 through a pin shaft, and the inner surface of the rotating wall 13 is rotatably connected with a material conveying roller 6. Through the arrangement, when the inner box 2 needs to be put into the outer box 1, the inner box 2 does not need to be lifted, only the rotating wall 13 needs to be opened, and the inner box 2 can be pushed into the outer box 1 through the material conveying roller 6.

[0057] For example, referring to Figure 8 and Figure 9The buffer 4 comprises a rotating disc 41, a rotating disc driving element 42, a roller shaft 43, and an annular air bag 44. The rotating disc 41 is rotatably connected to the upper surface of the bottom wall of the outer box 1 by a rotating shaft, and a receiving hole 45 is formed in the rotating disc 41. The rotating disc driving element 42 (for example, a stepping motor) can drive the rotating disc 41 to rotate by a predetermined angle. The roller shaft 43 is arranged in the receiving hole 45, and the two ends of the roller shaft 43 are rotatably connected to the two ends of the receiving hole 45. The annular air bag 44 is fixedly sleeved on the roller shaft 43.

[0058] In use, when the inner box 2 enters the outer box 1 from the feeding roller 6, the roller shaft 43 is parallel to the feeding roller 6, and therefore the combination of the roller shaft 43 and the annular air bag 44 can also function as a feeding element, facilitating the entry of the inner box 2 into the outer box 1.

[0059] Further, the rotating disc 41 can be rotated by a predetermined angle, and at this time, the inner box 2 and the outer box 1 are relatively inclined. When the inner box 2 and the outer box 1 are aligned, the shaking of the inner box 2 has a certain degree of consistency, and when the inner box 2 and the outer box 1 are relatively inclined, the positions of the inner box 2 and the outer box 1 are misaligned, and the frequency and degree of the pressing of the intermediate element 3 by the inner box 2 and the outer box 1 are increased, thereby improving the drying effect.

[0060] Further, the rotating disc 41 can also drive the inner box 2 to alternately and reciprocally swing, thereby actively pressing the hollow plate-shaped element and actively drying the inner box 2.

[0061] Further, in specific use, the roller shaft 43 and the annular air bag 44 have the following functions:

[0062] First, the roller shaft 43 and the annular air bag 44 can assist the entry and exit of the inner box 2.

[0063] Second, the roller shaft 43 and the annular air bag 44 have a buffering effect on the inner box 2.

[0064] Third, the roller shaft 43 and the annular air bag 44 can increase the shaking degree of the inner box 2, that is, increase the pressing degree of the hollow plate-shaped element, thereby improving the drying effect.

[0065] However, in many cases, the shaking degree of the inner box 2 does not need to be too large, and therefore the roller shaft 43 and the annular air bag 36 have the following functions: when the inner box 2 enters or exits, the roller shaft 43 and the annular air bag 36 can rotate to assist the entry and exit of the inner box 2; when the inner box 2 is located inside the outer box 1, the annular air bag 36 can support the inner box 2, thereby buffering the inner box 2; and further, the roller shaft 43 and the annular air bag 36 can be locked to reduce the shaking of the inner box 2.

[0066] Reference is made to Figure 9The two ends of the roller shaft 43 are provided with external threads 46 in opposite directions, and the pitches of the external threads 46 on the roller shaft 43 are sequentially increased in the direction away from the rotating wall 13; the roller shaft 43 is connected with a threaded sleeve 47 through the external threads 46, one end of the threaded sleeve 47 is attached to one end of the annular air bag 44; one side of the containing hole 45 is provided with a slide 48, and one side of the threaded sleeve 47 is fixedly connected with a sliding block 49 which is slidingly connected to the slide 48.

[0067] When the inner box 2 enters the outer box 1, the roller shaft 43 can rotate, and the threaded sleeve 47 is driven to move to one side of the annular air bag 44, so as to extrude the annular air bag 44; when the inner box 2 completely enters the outer box 1, the annular air bag 44 is extruded and attached to the side wall of the containing hole 45, so as to lock the roller shaft 43 and the annular air bag 44. In addition, the annular air bag 44 is extruded, so as to increase the supporting force of the annular air bag 44 on the inner box 2.

[0068] Referring to Figure 4 The inner surface of the outer side wall 12 is provided with a clamping groove 71, and the edge of the rotating disc 41 is fixedly connected with an arc-shaped clamping rod 72 which can be clamped into the clamping groove 71.

[0069] When the inner box 2 enters the outer box 1, the rotating disc 41 is required to rotate by a preset angle, so as to relatively incline the inner box 2 and the outer box 1. At the same time, the rotating disc 41 drives the arc-shaped clamping rod 72 to clamp into the clamping groove 71, so as to lock the rotating wall 13. Therefore, through the arrangement, the rotating wall 13 can be conveniently locked. When the rotating angle of the rotating disc 41 increases, not only the inclination degree of the inner box 2 can be increased, but also the inclination degree of the outer side wall 12 can be adjusted, so as to compress the inner box 2.

[0070] Through the arrangement, when the rotating disc 41 reciprocating swings, not only the inner box 2 can be alternately and reciprocating swung, so as to actively extrude the hollow plate-shaped member and actively dry the inner box 2, but also the rotating wall 13 can be small-amplitude reciprocating rotated, so as to extrude the inner box 2 and the hollow plate-shaped member and actively dry the inner box 2.

[0071] Referring to Figure 10 and Figure 11 The gap is provided with a humidity sensor 8, and the humidity sensor 8 is signal connected with the rotating disc driving member 42. When the air humidity reaches a preset value, the rotating disc driving member 42 can drive the rotating disc 41 to reciprocating move, so as to increase the drying speed of the inner box 2.

[0072] Working principle of the present application:

[0073] In use, the inner box 2 can be used separately from the outer box 1 or can be used in combination. The outer box 1 is stationary at a storage location, the inner box 2 is taken out of the outer box 1, transported to a loading location, loaded, then transported to the storage location, and the loaded inner box 2 is placed into the outer box 1. Since the inner box 2 is a paperboard box, the lightness and cushioning characteristics of the paperboard box can be fully utilized during the process, facilitating loading and transportation. After the inner box 2 is placed into the outer box 1, it can not only prevent humid air from entering, but also protect the inner box 2.

[0074] The goods are often in a state of shaking, and the inner box 2 and the outer box 1 do not shake synchronously, so the outer side wall 12 and the inner side wall 22 will squeeze the hollow plate-shaped member, thereby expelling the air in the hollow plate-shaped member to the gap and contacting the inner box 2 and the outer box 1, thereby drying the inner box 2 and the outer box 1 (the inner side wall 22 can also be dried, as long as the air outlet 32 is directed towards the inner side wall 22), and the hollow plate-shaped member can return to its original position and inhale air after the squeezing is released. During sea transportation, the hollow plate-shaped member inhales and expels air irregularly (not at a fixed time and quantity), which not only prevents humid air from entering, but also realizes drying of the inner box 2 and / or the outer box 1 without power.

[0075] The inner box 2 side wall is provided with a plurality of through holes 23, and the air outlet 32 is at least partially aligned with the through holes 23. Dry air can be squeezed into the inner box 2, thereby realizing air permeation and drying of the goods inside the inner box 2.

[0076] It should be noted that, in the present text, relational terms such as first and second and the like can only be used to distinguish one entity or operation from another entity or operation, without necessarily requiring or implying any such actual relationship or order between these entities or operations. Moreover, the terms "comprises", "comprising", or any other variant thereof are intended to cover non-exclusive inclusions, so that a process, method, article, or apparatus that includes a list of elements not only includes those elements, but also includes other elements not explicitly listed, or inherent to such a process, method, article, or apparatus.

[0077] Although embodiments of the present application have been shown and described, it will be understood by those of ordinary skill in the art that various changes, modifications, substitutions and alterations can be made thereto without departing from the principles and spirit of the application, the scope of which is defined by the following claims and their equivalents.
