Description

Technical Field

[0001] This application relates to the field of packaging technology, and in particular to a breathable and moisture-proof transport carton. Background Technology

[0002] Cardboard box packaging is a common packaging method. Cardboard box packaging has advantages such as affordability, ease of printing, light weight, and convenient transportation, and is widely used for sales packaging and transport packaging of goods.

[0003] When transporting items that require ventilation, ventilation holes are usually made in the cardboard boxes to allow air to circulate inside. However, moisture in the air can also circulate into the cardboard box through the ventilation holes. During the transportation process, the items transported inside the cardboard box may absorb moisture from the air, causing the items inside the box to become moldy and breed bacteria. Summary of the Invention

[0004] In order to improve the possibility that existing shipping cartons may become damp and cause damage to the transported goods, this application provides a breathable and moisture-proof shipping carton.

[0005] The breathable and moisture-proof transport carton provided in this application adopts the following technical solution:

[0006] A breathable and moisture-proof transport carton includes: a carton body with an open top; a lid covering the top of the carton body; a moisture-proof partition located below the carton body, wherein the bottom of the carton body has a group of vents, and the upper surface of the moisture-proof partition has a ventilated cavity communicating with the group of vents, and the moisture-proof partition has an air inlet connected to the ventilated cavity; and a desiccant placed in the ventilated cavity for drying the air flowing from the air inlet into the ventilated cavity, wherein the dried air then flows back into the carton body through the group of vents.

[0007] By adopting the above technical solution, the transported goods are placed inside the carton and the lid is closed for easy transport. During the transport of the goods, air can enter the ventilation cavity through the air inlet, and after being dried by the desiccant inside the ventilation cavity, it can circulate into the carton through the ventilation hole group. By setting the desiccant to dry the air, the possibility of the transported goods being moldy and damaged due to moisture in the existing transport carton can be reduced.

[0008] Optionally, the ventilation hole group includes a first ventilation hole and a second ventilation hole penetrating the bottom of the carton body; a partition is fixedly connected inside the moisture-proof box, and a flow hole group communicating with the ventilation cavity is opened on the partition; the flow hole group includes a first flow hole and a second flow hole penetrating the partition, the first flow hole being located below and communicating with the first ventilation hole, and the second flow hole being located below and communicating with the second ventilation hole; a compartment partition is also fixedly provided between the bottom of the moisture-proof box and the partition, the compartment partition being located between the first flow hole and the second flow hole; the compartment partition divides the ventilation cavity into a flow cavity communicating with the air inlet and a drying cavity for placing a desiccant, and an air handling hole communicating between the flow cavity and the drying cavity is penetrating the compartment partition; an opening and closing assembly for controlling the opening and closing of the air handling hole by sliding is provided between the partition and the compartment partition.

[0009] By adopting the above technical solution, and by setting an opening and closing component that controls the connection between the air handling hole and the flow cavity, the operator can control the air drying according to the ventilation conditions required by the items transported inside the carton.

[0010] When the items transported inside the carton require a dry and breathable environment, the opening and closing components control the connection between the air handling vent and the flow chamber. This allows air to enter the flow chamber through the air inlet and then through the air handling vent into the drying chamber. After being dried by the drying pack inside the drying chamber, the dried air can flow into the carton through the first flow vent and the first vent in sequence, thus meeting the transportation requirements of the product.

[0011] When the items transported inside the carton do not have requirements for the transportation environment, the air handling vents are sealed by the opening and closing components, preventing air from entering the drying chamber for drying. Instead, the air enters the circulation chamber and then flows directly into the carton body through the second circulation vent and the second vent. This reduces the use of desiccant packs, minimizes resource waste while ensuring normal transport of goods, and increases the applicability of moisture-proof boxes.

[0012] Optionally, the partition plate has a second control cavity communicating with the air handling hole, and the partition plate has a first control cavity communicating with the second control cavity, and the first control cavity, the first flow hole, and the second flow hole are interconnected; the opening and closing assembly includes: a first baffle plate, which is slidably connected to the first control cavity; a second baffle plate, which is fixedly connected to the lower surface of the first baffle plate and slidably connected to the second control cavity; when the first baffle plate blocks the first flow hole, the second baffle plate blocks the air handling hole; when the first baffle plate blocks the second flow hole, the second baffle plate separates from the air handling hole.

[0013] By adopting the above technical solution, when the items transported inside the carton require a dry air circulation environment, the first baffle is slid until it blocks the second flow hole. When the first baffle blocks the second flow hole, the second baffle can separate from the air treatment hole. At this time, air flows from the air inlet to the flow chamber, and then from the flow chamber to the air treatment hole to the drying chamber. The drying pack in the drying chamber can dry the air. The dried air can flow from the first flow hole to the first vent hole, and then from the first vent hole to the carton body.

[0014] When the items transported inside the carton do not affect the air humidity, slide the first baffle until it blocks the first flow hole. At this time, the second baffle can block the air handling hole, allowing the air entering the moisture-proof compartment through the air inlet to flow directly into the carton through the second flow hole and the second vent hole, reducing the waste of desiccant packs and improving the applicability of the moisture-proof compartment.

[0015] Optionally, the side wall of the moisture-proof box is provided with a sliding groove, and the side wall of the first baffle is connected to a movable rod that is slidably connected to the sliding groove.

[0016] By adopting the above technical solution, the first barrier can be moved by moving the moving rod, and the movement of the first barrier can realize the movement of the second barrier, making the operation process more convenient.

[0017] Optionally, the moisture-proof box is further provided with a first slot and a second slot, both of which are connected to the slide groove, and the first slot and the second slot are sequentially positioned below the two sides of the slide groove that are far apart from each other; when the moving rod is engaged in the first slot, the first baffle blocks the second flow hole; when the moving rod is engaged in the second slot, the first baffle blocks the first flow hole.

[0018] By adopting the above technical solution, and by setting the first slot and the second slot, which represent two gear switches, during the movement of the first baffle, the moving rod can be pulled upward as needed, and then moved in the slide groove. When the moving rod is placed in the first slot or the second slot, the pulling of the moving rod is released, so that the moving rod can be locked in the first slot or the second slot, thus completing the limitation of the moving rod, making the movement process more convenient.

[0019] Optionally, the carton body is fixedly connected to a plug rod, and the upper surface of the moisture-proof box is provided with an inwardly opening for the plug rod to be inserted.

[0020] By adopting the above technical solution, before transporting the carton body, the insertion rod of the carton body is inserted into the corresponding insertion hole. The insertion hole limits the insertion rod, thus limiting the insertion rod. The operation process is relatively convenient and the moisture-proof partition can be reused.

[0021] Optionally, a reinforcing component is provided between the plug rod and the plug hole.

[0022] By adopting the above technical solution and setting up reinforcement components, the tightness of the connection between the plug rod and the plug hole can be increased, further increasing the tightness of the connection between the carton body and the moisture-proof partition.

[0023] Optionally, each of the reinforcing components includes: a first magnet, which is fixedly connected to the lower surface of the plug rod; and a second magnet, which is fixedly disposed on the bottom wall of the plug hole, wherein the first magnet and the second magnet are attracted to each other.

[0024] By adopting the above technical solution, the magnetic attraction between the first magnet and the second magnet increases the tightness of the connection between the plug rod and the moisture-proof box. Furthermore, during the disassembly of the moisture-proof box, only greater force is needed to separate the two parts, making the operation process relatively convenient.

[0025] Optionally, the moisture-proof box is provided with an operating hole that communicates with the drying chamber. The wall of the operating hole is rotatably connected to a baffle for blocking the operating hole. Fixing components for fixing the baffle are provided on both sides of the baffle that are far apart from each other and between the moisture-proof box.

[0026] By adopting the above technical solution, after the desiccant in the moisture-proof compartment fails, the fixing component can be released from the baffle, and then the baffle can be rotated to expose the operating hole. The desiccant placed in the moisture-proof compartment can then be taken out through the operating hole for replacement, making the operation process relatively convenient.

[0027] Optionally, each of the fixing components includes: a fixing rod that passes through the moisture-proof box and is inserted into the baffle; a follower spring that is sleeved on the fixing rod and coaxially arranged with the fixing rod; and a fixing block that is fixedly connected to the end of the fixing rod away from the baffle, and the follower spring is fixedly disposed between the fixing block and the follower spring.

[0028] By adopting the above technical solution, when the baffle is rotated in the direction away from the moisture-proof compartment, the fixing block moves in the direction away from the moisture-proof compartment. The movement of the fixing block drives the fixing rod to move, and the follow-up spring is compressed until the fixing rod separates from the baffle. Then the baffle can be rotated. The operation process is relatively convenient.

[0029] After replacing the desiccant pack, rotate the baffle towards the moisture-proof compartment to a suitable position, and then insert the fixing rod through the moisture-proof compartment and into the baffle. The operation is quite convenient.

[0030] In summary, this application includes at least one of the following beneficial technical effects:

[0031] 1. By setting up a moisture-proof compartment and placing a desiccant pack inside the moisture-proof compartment to dry the air entering the compartment, the dried air can circulate through the ventilation holes into the carton body, satisfying the dry and breathable environment required by the carton body. This can effectively improve the situation where moisture may enter the carton and cause the transported goods to become damp and moldy.

[0032] 2. By setting a partition, the ventilated cavity is divided into a flow cavity and a drying cavity for placing the desiccant pack. The flow between the flow cavity and the air handling holes on the partition is controlled by the opening and closing component. This allows the moisture-proof box to be used for carton bodies that transport different types of goods, increasing the applicability of the moisture-proof box. Attached Figure Description

[0043] The following is in conjunction with the appendix Figure 1-9 This application will be described in further detail.

[0044] This application discloses a breathable and moisture-proof transport cardboard box, referring to... Figures 1 to 4 The system includes a cardboard box body 1, which is used to carry transported goods. The cardboard box body 1 is a rectangular box with an open top. The top of the cardboard box body 1 is covered with a box lid 2, which can cover the opening of the cardboard box body 1. A moisture-proof compartment 3 is provided below the cardboard box body 1. A ventilation cavity 31 is opened inward on the upper surface of the moisture-proof compartment 3. An air inlet 32 ​​is opened on one side wall of the moisture-proof compartment 3, which is connected to the ventilation cavity 31. A ventilation hole group 11 is provided at the bottom of the cardboard box body 1, and the ventilation hole group 11 is connected to the ventilation cavity 31.

[0045] Reference Figure 2 and Figure 3 The moisture-proof box 3 is also equipped with a desiccant 4, which is stored in the ventilated cavity 31. The desiccant 4 can dry the air that enters the ventilated cavity 31 from the air inlet 32, and then the dried air flows into the carton body 1 through the vent group 11.

[0046] Reference Figure 2 and Figure 4During the transportation of cardboard boxes, the goods to be transported are placed inside the cardboard box body 1, and then the box lid 2 is closed on the top of the cardboard box body 1. Outside air flows through the air inlet 32 ​​to the ventilation cavity 31. The desiccant 4 inside the ventilation cavity 31 can dry the air. The dried air then flows back into the cardboard box body 1 through the ventilation hole group 11. This not only meets the ventilation requirements of the transported goods, but also the desiccant 4 inside the moisture-proof box 3 can dry the air, reducing the problem that moisture entering the cardboard box body 1 may cause the goods inside the cardboard box body 1 to become moldy and breed bacteria. This improves the possibility that the existing transport cardboard boxes may become damp and cause damage to the transported goods.

[0047] Reference Figure 2 and Figure 3 A partition 33 is fixedly connected to the top of the moisture-proof box 3. The partition 33 is horizontally set, and a group of flow holes 331 is opened on the partition 33. The group of flow holes 331 communicates with the ventilated cavity 31 (in conjunction with...). Figure 4 The flow hole group 331 is connected to the ventilation hole group 11. The ventilation hole group 11 includes a first ventilation hole 111 and a second ventilation hole 112. The first ventilation hole 111 and the second ventilation hole 112 are both disposed through the bottom of the carton body 1, and the first ventilation hole 111 and the second ventilation hole 112 are arranged diagonally.

[0048] Reference Figure 2 The flow hole group 331 includes a first flow hole 3311 and a second flow hole 3312. Both the first flow hole 3311 and the second flow hole 3312 are disposed through the partition 33 and are arranged diagonally. The first flow hole 3311 is located directly below the first vent hole 111 and is connected to the first vent hole 111. The second flow hole 3312 is located directly below the second vent hole 112 and is connected to the second vent hole 112.

[0049] Reference Figure 2 and Figure 3 The moisture-proof box 3 is also equipped with a partition plate 5. The partition plate 5 is vertically arranged and fixedly connected to the inner wall of the moisture-proof box 3. The partition plate 5 is placed between the first flow hole 3311 and the second flow hole 3312.

[0050] Reference Figure 4 and Figure 5 The partition plate 5 divides the ventilated cavity 31 into a flow cavity 311 and a drying cavity 312. An air treatment hole 51 extends through the partition plate 5, connecting the flow cavity 311 and the drying cavity 312. The flow cavity 311 and the second flow hole 312 are connected, and the drying cavity 312 and the first flow hole 311 are connected (in combination). Figure 2 and Figure 5 The drying package 4 is placed inside the drying chamber 312.

[0051] Air enters the flow chamber 311 through the air inlet 32, and then reaches the drying chamber 312 through the air treatment hole 51 for drying. The dried air then passes through the first flow hole 3311 and the first vent hole 111 in sequence before reaching the carton body 1, thereby achieving the drying of the air.

[0052] Reference Figure 2 and Figure 5 The partition 33 has a first control cavity 332 inside, and the first control cavity 332, the first flow hole 3311 and the second flow hole 3312 are connected. The partition 5 has a second control cavity 52 inside, and the second control cavity 52 is connected to the air treatment hole 51. At the same time, the second control cavity 52 is connected to the first control cavity 332. An opening and closing component 6 is provided between the partition 33 and the partition 5. The opening and closing component 6 controls the opening and closing of the air treatment hole 51 by sliding, controls the flow between the air treatment hole 51 and the flow cavity 311, and thus controls the dryness of the flow air.

[0053] The opening and closing assembly 6 controls the flow between the air treatment hole 51 and the flow cavity 311. When it is necessary to circulate dry air into the carton body 1, the opening and closing assembly 6 controls the flow between the air treatment hole 51 and the flow cavity 311, so that the air can flow into the drying cavity 312 for drying, and then reach the carton body 1 through the first flow hole 3311 and the first vent hole 111, thereby achieving the drying of the air and meeting the need for dry air circulation for the items inside the carton body 1.

[0054] When there is no requirement for air during the transportation of the items inside the carton body 1, the opening and closing component 6 controls the non-flow between the air handling hole 51 and the flow cavity 311, thereby meeting the transportation requirements of the items inside the carton body 1 while reducing the waste of the desiccant pack 4 and saving resources.

[0055] Reference Figure 3 and Figure 4 The opening / closing assembly 6 includes a first baffle 61, which is horizontally positioned and slidably connected to the first control cavity 332. The size of the first baffle 61 is larger than both the size of the first flow hole 3311 and the size of the second flow hole 3312. A second baffle 62 is fixedly connected to the lower surface of the first baffle 61, which is vertically positioned and slidably connected to the second control cavity 52. ​​When the first baffle 61 blocks the first flow hole 3311, the second baffle 62 blocks the air handling hole 51; when the second baffle 62 blocks the second flow hole 3312, the second baffle 62 separates from the air handling hole 51.

[0056] When the items inside the carton body 1 require dry air, the first baffle 61 is moved. The movement of the first baffle 61 can drive the second baffle 62 to move until the first baffle 61 can block the second flow hole 3312. At this time, the air that enters the flow chamber 311 through the air inlet 32 ​​can flow into the drying chamber 312 through the air treatment hole 51. The drying pack 4 in the drying chamber 312 can dry the air that flows into the drying chamber 312. The dried air then flows into the carton body 1 through the first flow hole 3311 and the first vent hole 111.

[0057] When the items inside the carton body 1 do not require dry air, the first baffle 61 is moved. The movement of the first baffle 61 can drive the second baffle 62 to move, so that the first baffle 61 can block the first flow hole 3311 and block the air treatment hole 51.

[0058] Reference Figure 6 and Figure 7 The side wall of the first baffle 61 is connected to a movable rod 611. The length direction of the movable rod 611 is parallel to the length direction of the first baffle 61. The side wall of the moisture-proof box 3 is fixedly provided with a sliding groove 34. The length direction of the sliding groove 34 is perpendicular to the length direction of the movable rod 611, and the movable rod 611 is slidably inserted into the sliding groove 34.

[0059] When the items transported inside the carton body 1 require dry air, the moving rod 611 can move the first baffle 61, which in turn moves the second baffle 62, thus opening the first flow hole 3311 and the air treatment hole 51 and closing the second flow hole 3312. This allows air to enter the flow chamber 311 through the air inlet 32 ​​and then flow through the air treatment hole 51 to the drying chamber 312 for processing. The dried air then flows into the carton body 1 through the first flow hole 3311 and the first vent hole 111.

[0060] When the items transported inside the carton body 1 do not require specific humidity levels, the first baffle 61 can be moved by moving the moving rod 611. The movement of the first baffle 61 can drive the movement of the second baffle 62, so that the first baffle 61 can block the first flow hole 3311 and the second baffle 62 can block the air treatment hole 51. This allows air in the air to enter the flow cavity 311 through the air inlet 32, then enter the second flow hole 3312 through the flow cavity 311, then enter the second vent hole 112 through the second flow hole 3312, and finally enter the carton body 1 through the second vent hole 112, reducing the waste of the desiccant pack 4.

[0061] By setting the first baffle 61 and the second baffle 62, the air entering the carton body 1 can be dried, allowing operators to adjust the ventilation environment according to the transported goods inside the carton body 1, effectively improving the applicability of the moisture-proof partition box 3.

[0062] Reference Figure 6 and Figure 7 Specifically, a connecting rod 6111 is fixedly connected to one end of the movable rod 611 near the first baffle 61. A limiting block 6112 is fixedly connected to the side of the connecting rod 6111 away from the movable rod 611. A sliding groove 612 is provided inward on the side of the first baffle 611 near the movable rod 611. The length direction of the sliding groove 612 is vertical. The connecting rod 6111 is slidably connected to the sliding groove 612, and the sliding direction of the connecting rod 6111 is the length direction of the sliding groove 34. A limiting groove 613 is also provided on the first baffle 61. The limiting groove 613 communicates with the sliding groove 612, and the limiting block 6112 is slidably connected to the limiting groove 613. The cross-sectional area of ​​the limiting block 6112 is larger than the cross-sectional area of ​​the connecting rod 6111. The length direction of the sliding groove 612 is perpendicular to the length direction of the movable rod 611.

[0063] Reference Figure 5 and Figure 6 The moisture-proof box 3 is also provided with a first slot 35 and a second slot 36. The first slot 35 and the second slot 36 are both located below the sliding groove 612. The first slot 35 and the second slot 36 are placed on opposite sides of the sliding groove 34. The first slot 35 and the second slot 36 are both connected to the sliding groove 34.

[0064] Reference Figure 6 and Figure 7 When the moving rod 611 is engaged in the first slot 35, the first baffle 61 blocks the second flow hole 3312, and the second baffle 62 separates from the air treatment hole 51; when the moving rod 611 is engaged in the second slot 36, the first baffle 61 blocks the first flow hole 3311, and the second baffle 62 blocks the air treatment hole 51.

[0065] The first slot 35 and the second slot 36 are two position switches. When the moving rod 611 is engaged in the first slot 35, dried air can enter the carton body 1; when the moving rod 611 is engaged in the second slot 36, undried air can enter the carton body 1. This ensures the essential ventilation environment for transported goods while reducing the waste of the desiccant pack 4.

[0066] Reference Figure 2 and Figure 8Each of the four corners of the lower surface of the carton body 1 is fixedly connected with a plug rod 7. The plug rod 7 is set vertically. Each of the four corners of the upper surface of the moisture-proof box 3 has an inwardly opened plug hole 37. The plug hole 37 and the plug rod 7 correspond one-to-one, and each plug rod 7 is inserted into the corresponding plug hole 37.

[0067] When the goods being transported by the carton body 1 require ventilation, a moisture-proof partition 3 is installed at the bottom of the carton body 1, so that the four plug-in rods 7 at the four corners of the lower surface of the carton body 1 can be plugged into the corresponding plug-in holes 37, thus completing the installation of the moisture-proof partition 3.

[0068] Reference Figure 8 To increase the stability of the moisture-proof partition box 3 during installation, a reinforcing component 8 is provided between each plug rod 7 and the corresponding plug hole 37. The reinforcing component 8 is used to strengthen the tightness of the connection between the plug rod 7 and the moisture-proof partition box 3, and reduce the possibility of the moisture-proof partition box 3 separating from the carton body 1 during transportation.

[0069] Reference Figure 8 Each reinforcing component 8 includes a first magnet 81 and a second magnet 82. Each first magnet 81 is fixedly connected to the lower surface of the corresponding plug rod 7, and each second magnet 82 is fixedly connected to the bottom wall of the corresponding plug hole 37. Each first magnet 81 abuts and attracts the corresponding second magnet 82.

[0070] Reference Figure 3 In order for the moisture-proof compartment 3 to be reused multiple times, an operation hole 38 is provided on the side of the moisture-proof compartment 3 away from the slide 34. The size of the operation hole 38 is large enough to allow the drying package 4 to pass through. A baffle 39 is hinged to the inner wall of the operation hole 38. Fixing components 9 are provided on both sides of the baffle 39 that are far apart from each other and between the moisture-proof compartment 3. The fixing components 9 are used to fix the baffle 39.

[0071] When it is necessary to replace the desiccant 4, release the two fixing components 9 from fixing the baffle 39, and then rotate the baffle 39 away from the moisture-proof compartment 3. Then replace the desiccant 4 through the operating hole 38. After replacement, rotate the baffle 39 towards the side closer to the moisture-proof compartment 3, and then use the two fixing components 9 to fix the baffle 39.

[0072] Reference Figure 3 and Figure 9Each fixing component 9 includes a fixing rod 91, a fixing block 92, and a follower spring 93. Each fixing block 92 is fixedly connected to the end of the corresponding fixing rod 91. Each fixing rod 91 passes through the moisture-proof box 3 and is inserted into the baffle 39. The follower spring 93 is sleeved on the outside of the corresponding fixing rod 91, and each follower spring 93 is coaxially arranged with the corresponding fixing rod 91. One end of each follower spring 93 is fixedly connected to the fixing block 92, and the other end of each follower spring 93 is fixedly connected to the side wall of the moisture-proof box 3.

[0073] When it is necessary to release the baffle 39, move the fixing block 92 away from the moisture-proof box 3. The movement of the fixing block 92 causes the fixing rod 91 to move, and the follower spring 93 is compressed until the fixing rod 91 separates from the moisture-proof box 3, thus releasing the fixation of the fixing rod 91.

[0074] The implementation principle of a breathable and moisture-proof transport carton in this application embodiment is as follows: When the items transported inside the carton body 1 require dry air, the insertion rod 7 of the carton body 1 is inserted into the insertion hole 37 of the moisture-proof partition box 3, so that the first magnet 81 and the corresponding second magnet 82 attract each other. Then, the moving rod 611 is pulled upward so that the moving rod 611 can slide in the slide groove 34. When the moving rod 611 is placed above the first slot 35, the sliding of the moving rod 611 is stopped, and the moving rod 611 is locked in the first slot 35. At this time, the first baffle 39 blocks the second flow hole 3312, and the second baffle 62 is separated from the air treatment hole 51. Air can enter the flow cavity 311 from the air inlet 32, and then enter the drying cavity 312 through the air treatment hole 51.
