[0031] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they cannot be understood as limitations on the present invention.

[0033] In the description of this utility model, "several" means more than one, "plurality" means more than two, "greater than," "less than," and "exceed" are understood to exclude the number itself, while "above," "below," and "within" are understood to include the number itself. The use of the terms "first" and "second" is solely for the purpose of distinguishing technical features and is not to be construed as indicating or implying relative importance, implicitly specifying the number of the indicated technical features, or implicitly specifying the order of the indicated technical features.

[0034] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0035] During the transportation of fruits and vegetables, a certain amount of water vapor will be generated in the packaging box due to the respiration of fruits and vegetables, temperature, humidity, and refrigerated transportation. If not handled in time, water will accumulate in the packaging box and cause the fruits and vegetables to rot. For this reason, some technologies set a gas-water permeable membrane on the side wall of the packaging box to discharge the water vapor in the packaging box through the gas-water permeable membrane. However, in actual use, since the water vapor in the box is concentrated and flows toward the gas-water permeable membrane, the water vapor solubility around the fruits and vegetables near the water vapor permeable membrane is relatively high, which makes the fruits and vegetables in this area prone to rot.

[0036] Based on the above problems, the present invention provides a packaging box that can be used for fruit and vegetable packaging and avoids the accumulation of water vapor in the packaging box, thereby reducing the risk of fruit and vegetable rot. This application takes fruit and vegetable packaging as an example, but is not limited to packaging only fruits and vegetables. It can be used for any product that needs to absorb water vapor during storage or transportation. Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of the structure of the packaging box of an embodiment of the utility model. Figure 2 for Figure 1The exploded view shows that the packaging box of this embodiment includes: an outer box 100 and a water-absorbing member 200. The water-absorbing member 200 is arranged in the accommodating cavity 111 of the outer box 100. The water-absorbing member 200 has a storage portion 210 and a sealing portion 220. The storage portion 210 has a storage cavity 211 and a second storage opening 212 connected to the storage cavity 211. The storage cavity 211 is used to accommodate fruit and vegetable products. The sealing portion 220 can be movably connected to the storage portion 210 to selectively close or open the first storage opening 112. When using the packaging box of this embodiment to pack fruits and vegetables, the fruits and vegetables are placed into the storage cavity 211 through the second storage opening 212, and the second storage opening 212 is sealed by the sealing portion 220. Therefore, for the fruits and vegetables in the storage cavity 211, the surrounding area is an absorption environment, so that water vapor moves evenly to the surrounding area in all directions, and does not form a situation where water vapor accumulates in a certain area, thereby reducing the risk of fruit and vegetable rot.

[0037] Specifically, the outer box 100 is, for example, a cardboard box, a foam box, a plastic box, or a wooden box. The outer box 100 includes a box body 110 and a cover 120. The box body 110 has a receiving cavity 111 and a first storage opening 112 connected to the receiving cavity 111. The cover 120 is movably connected to the box body 110 to close the first storage opening 112. The connection between the cover 120 and the box body 110 includes, but is not limited to, a detachable connection, a movable connection, or a rotatable connection, as long as the first storage opening 112 can be opened or closed. The rotatable connection can be achieved by a structure such as a hinge, a pin, or a flexible member. For example, the outer box 100 is a cardboard box, that is, the box body 110 and the cover 120 are connected by a paper with a certain degree of flexibility, so that the cover 120 can be flipped relative to the box body 110 to achieve the opening and closing of the first storage opening 112.

[0038] The absorbent member 200 is disposed in the accommodating chamber 111. The absorbent member 200 may be a water-absorbing structure made of absorbent cotton, absorbent paper, non-woven fabric, or absorbent board. The absorbent member 200 includes a storage portion 210 and a sealing portion 220. The storage portion 210 has a storage chamber 211 and a second storage opening 212 connected to the storage chamber 211. The storage chamber 211 is used to accommodate items to be packaged (such as fruits and vegetables). The sealing portion 220 is movably connected to the storage portion 210, and fruits and vegetables can be placed into the storage chamber 211 from the second storage opening 212. The sealing portion 220 is used to optionally close and open the second storage opening 212. Similarly, the connection method between the sealing portion 220 and the storage portion 210 includes but is not limited to a detachable connection, a movable connection, or a rotating connection, as long as the first storage opening 112 can be opened or closed. Furthermore, when the absorbent member 200 is an integrated flexible bag-shaped structure, the second storage opening 212 can be opened and closed by deforming the absorbent member 200 itself. For example, the absorbent member 200 can be deformed at the sealing portion 220 by bundling to tighten the sealing portion 220 and close the second storage opening 212. The absorbent member 200 is detachably connected to the outer box 100 or is connected to the outer box 100 as an integrated structure. For example, the absorbent member 200 is made of absorbent paper, and the bottom wall and side walls of the accommodating cavity 111 are covered with absorbent paper to enclose the storage portion 210. The absorbent paper is not connected to each other. After the fruits and vegetables are placed in the storage portion 210, a piece of absorbent paper is placed on the top of the storage portion 210 as a cover. Alternatively, the absorbent paper can be connected to each other to form an integrated structure. During packaging, the integrated absorbent member 200 can be directly placed in the accommodating cavity 111 without having to lay out the absorbent paper one by one. Specifically, whether the absorbent paper is spliced ​​together or integrated, it is detachably connected to the outer box 100. Therefore, after use, when the absorbent member 200 cannot be reused, it can be discarded or dried separately, making the packaging box reusable, thereby saving costs. Furthermore, different fruits and vegetables produce varying amounts of water vapor during respiration and require varying humidity levels for freshness preservation. Therefore, when packaging fruits and vegetables using the packaging box of this embodiment, different absorbent members 200 can be selected based on the specific fruit and vegetable.

[0039] The absorbent member 200 is integrally connected to the outer box 100 by adhering absorbent paper to the inner wall of the outer box 100. It is understood that due to the flexibility of absorbent paper, if it is not supported, the absorbent member 200 will collapse, preventing the fruits and vegetables from being placed in the storage cavity 211. In this embodiment, the absorbent paper is adhered to the inner wall of the outer box 100, providing support for the absorbent member 200. Furthermore, the sealing portion 220 of the absorbent member 200 is attached to the lid 120. Therefore, when the first storage opening 112 is sealed, the second storage opening 212 is also sealed, making the packaging box easier to use.

[0040] In some embodiments, the outer box 100 is a corrugated aluminum foil box or a honeycomb aluminum foil box. The outer box 100 made of corrugated aluminum foil cardboard has good thermal insulation properties to ensure that fruits and vegetables are kept within a suitable temperature range during transportation, reducing nutrient loss and quality degradation due to temperature changes. The suitable temperature helps to extend the shelf life of fruits and vegetables and reduce losses caused by rot and deterioration. The inner layer of aluminum foil can also increase waterproof, oil-proof and folding resistance to increase the service life of the outer box 100. Corrugated aluminum foil cardboard includes single-layer corrugated cardboard and double-layer corrugated cardboard. When single-layer corrugated cardboard is selected, the cardboard thickness is greater than 3mm to ensure that the outer box 100 has sufficient strength. Similarly, double-layer corrugated cardboard needs to ensure a thickness of greater than 5mm. The honeycomb sandwich structure of the honeycomb cardboard is a closed small chamber, which has good sound insulation and thermal insulation properties, so that the packaging box of this embodiment has good sound insulation and thermal insulation properties.

[0041] In some embodiments, the storage portion 210 and the sealing portion 220 are connected to form an integrated flexible absorbent bag, that is, the absorbent member 200 is configured as a flexible absorbent bag. Specifically, the absorbent member 200 is made of a flexible material such as absorbent cotton, non-woven fabric, or flexible absorbent resin. As a result, the absorbent member 200 not only absorbs water but also acts as a buffer and shock absorber, thereby reducing the risk of damage to fruits and vegetables during transportation and improving the quality of fruit and vegetable delivery. In addition, during the fruit and vegetable packing process, the fruits and vegetables can be placed in the absorbent bag first, and then placed into the receiving chamber 111 through the absorbent bag, making the packaging of fruits and vegetables more flexible. For example, taking apple picking as an example, in order to ensure the quality of apples, they usually need to be picked manually one by one. During the picking process, workers can use the water-absorbing member 200 of this embodiment as a picking bag and directly place the apples in the water-absorbing member 200. When the number of apples in the water-absorbing member 200 is reached, the water-absorbing member 200 can be directly placed into the outer box 100 to seal the box directly without the need for secondary bagging, which makes the apple packaging process simpler and reduces the packaging labor cost.

[0042] Figures 3 to 5 , Figure 3 This is a schematic diagram of the structure of the water-absorbing bag in the utility model. Figure 4 It is a structural diagram of the water absorbing part and the box body. Figure 5This is a schematic diagram of the structure of another packaging box according to the present invention. In some embodiments, a sealing portion 220 can extend from the first storage opening 112 and connect to the outer box 100, keeping the second storage opening 212 open for fruits and vegetables to be placed into the storage cavity 211 through the second storage opening 212. Specifically, because the absorbent member 200 is a flexible structure, some support is required to maintain the second storage opening 212 open during the packaging process. To facilitate fruit and vegetable packaging, the sealing portion 220 can be connected to the outer box 100 to maintain the second storage opening 212 open without requiring additional manual support. The connection between the sealing portion 220 and the outer box 100 includes abutment, direct connection or indirect connection through other structural members. For example, the cover 120 of the outer box 100 is detachably connected to the box body 110, or the cover 120 is rotatably connected to the box body 110. The sealing portion 220 is an annular flexible structure connected along the edge of the second storage opening 212 (such as Figure 3 As shown), during the packaging process, the cover 120 is first removed, or the cover 120 is rotated to fit the outer wall of the box body 110, and then the sealing portion 220 is extended from the first storage opening 112 and folded outward to be sleeved on the outer wall of the outer box 100, so that the second storage opening 212 remains in an open state (as shown). Figure 4 As shown). Alternatively, in some embodiments, the sealing portion 220 includes a plurality of second cover portions 221, and at least two of the plurality of second cover portions 221 (hereinafter referred to as the second cover portion 221a and the second cover portion 221b for the convenience of description) are disposed opposite to each other at the edge of the second storage opening 212. The cover body 120 includes a plurality of first cover portions 121, and at least two of the plurality of first cover portions 121 (hereinafter referred to as the first cover portion 121a and the first cover portion 121b for the convenience of description) are disposed opposite to each other at the edge of the first storage opening 112. During the packaging process, in order to keep the second storage opening 212 in an open state, the second cover portion 221a and the second cover portion 221b are folded in opposite directions and respectively pressed against the first cover portion 121a and the first cover portion 121b (as shown). Figure 5 shown).

[0043] It is understandable that if the sealing portion 220 is turned outward and sleeved on the outer wall of the outer box 100, the diameter of the sealing portion 220 cannot be smaller than the diameter of the box body 110. Therefore, the structure of the water-absorbing bag is restricted, which increases the design cost. For another example, if the second cover 221 is directly abutted against the first cover 121, there is a risk that the second cover 221 will slip off. Based on this, refer to Figure 5 and Figure 6 , Figure 6 for Figure 5Schematic diagram of the structure of the absorbent member. In some embodiments, the absorbent member 200 further includes a hooking portion 230, which can be a hook, a loop, or a connecting strap. For example, the absorbent member 200 includes multiple hooks positioned along the second storage opening 212. During packaging, the multiple hooks are attached to the edge of the first storage opening 112 of the outer box 100. The hooks are then used to pull the sealing portion 220, thereby opening the second storage opening 212. It can be seen that connecting the outer box 100 via the hooking portion 230 not only eliminates the caliber of the sealing portion 220, but also allows the sealing portion 220 to be more stably attached to the outer box 100.

[0044] Reference Figure 5 and Figure 6 In some embodiments, the outer box 100 is a rectangular box body 110, and the cover body 120 includes multiple first cover portions 121. At least two of the multiple first cover portions 121 are positioned opposite each other at the edge of the first storage opening 112. The first cover portions 121 are rectangular in structure. The hook portion 230 is connected to the outer surface of the second cover portion 221 and forms a hook groove with the second cover portion 221. Therefore, during the packaging process, the end of the first cover portion 121 facing away from the box body 110 can be inserted into the hook groove, thereby achieving hooking between the second cover portion 221 and the first cover portion 121. Furthermore, on this basis, the first cover portion 121 has two first corners 1211 facing away from the box body 110, and the two second cover portions 221 are both connected to a hanging portion 230. The hanging portion 230 and the second cover portion 221 define a hanging groove. The first corner 1211 of each first cover portion 121 can be inserted into the hanging groove without the need for the entire end of the first cover portion 121 to be inserted into the hanging groove. This not only saves the amount of material used in the manufacture of the water-absorbing member 200, but also makes the hanging between the second cover portion 221 and the first cover portion 121 simpler, thereby making the fruit and vegetable packaging process simpler and improving packaging efficiency. Specifically, for example, the absorbent bag is a rectangular box body 110 adapted to the outer box 100, the second cover 221 is a rectangular structure, and the second cover 221 has two second corners 2211 facing away from the support portion. The hanging portion 230 is a right-angled triangle structure. The hanging portion 230 is connected to the second corner 2211 of the second cover 221. The two right-angled sides of the hanging portion 230 are respectively connected to the two sides of the second corner 2211. The hypotenuse faces the central area of ​​the second cover 221 and is not connected to the second cover 221, thereby defining a triangular hanging groove with an opening facing the central area with the second cover 221. During the packaging process, the first corner 1211 of the first cover 121 is inserted into the corresponding hanging groove to achieve connection with the second cover 221, so as to pull the storage portion 210 to keep the second storage opening 212 in an open state.

[0045] Reference Figure 7 , Figure 7 for Figure 1In a cross-sectional view, in some embodiments, the packaging box further includes a protective member 300, which is a flexible structure and is connected to the bottom of the water-absorbing member 200. Specifically, it can be understood that the bottom of the storage portion 210 is the main force-bearing part for supporting fruits and vegetables. Therefore, in order to ensure the quality of fruits and vegetables, the packaging box of this embodiment also includes a protective member 300. The protective member 300 can be a flexible structure such as pearl cotton, sponge, or foam to further cushion the fruits and vegetables, thereby improving the quality of fruits and vegetables and reducing the noise generated by vibration during the transportation of fruits and vegetables. Furthermore, on this basis, the protective member 300 is detachably connected to the outer box 100. Therefore, protective members 300 of different softness or thickness can be used according to different types of fruits and vegetables. For example, when packaging durian and apples, since apples are relatively more fragile and more easily crushed than durian, a softer and thicker protective member 300 is selected when packaging apples to prevent them from being crushed and improve transportation quality.

[0046] Reference Figure 2 In some embodiments, the packaging box further includes an air conditioner 400 for regulating the oxygen concentration within the packaging box to maintain it within the minimum range required for normal respiration of fruits and vegetables, thereby reducing the rate of decay and effectively preventing the intrusion of harmful bacteria such as mold from outside the box. This, in turn, maintains the quality of fruits and vegetables, reduces waste, and extends their storage and shelf life. Specifically, the outer box 100 has a mounting hole 113 that communicates with the accommodating chamber 111. The packaging box further includes an air conditioner 400, which is connected to the box body 110 and covers the mounting hole 113 and is used to regulate the oxygen concentration within the accommodating chamber 111. It is understood that oxygen is a crucial factor for the normal respiration of fruits and vegetables. At an appropriate oxygen concentration, fruits and vegetables can undergo aerobic respiration, sustaining their vital activities and generating energy. However, when the oxygen concentration is too high, the fruit's respiration is enhanced, resulting in faster organic matter consumption and increased heat release, which may accelerate aging and decay. On the other hand, if the oxygen concentration is too low, the fruit may be forced to undergo anaerobic respiration. Anaerobic respiration produces alcohol and carbon dioxide, which not only affect the taste and flavor of the fruit but may also damage the fruit cells, causing the fruit to rot. This embodiment can effectively improve this problem. When the oxygen concentration inside the packaging box is higher than outside, oxygen will permeate outward through the air-regulating element 400. Conversely, if the external oxygen concentration is higher, oxygen will permeate into the accommodating cavity 111 through the air-regulating element 400. The air permeability of the air-regulating element 400 controls the speed of oxygen inflow and outflow, thereby adjusting the solubility of oxygen in the accommodating cavity 111. Furthermore, in order to improve the uniformity of oxygen in the accommodating cavity 111, the packaging box includes multiple air-regulating elements 400, which are evenly distributed on the outer box 100.

[0047] Furthermore, it can be known that the minimum oxygen concentration required for respiration of different types of fruits and vegetables is also different. Based on this, on the basis of the above embodiment, the air-regulating member 400 is detachably connected to the box body 110 by plugging, threading, rotating and snapping. Thus, when transporting different types of fruits and vegetables, different air-regulating members 400 can be selected to improve the practicality of the packaging box of this embodiment. For example, when cherries are packaged in the packaging box of this embodiment, since the minimum oxygen concentration required for cherries to breathe is 3% to 5%, a breathable member with an air permeability of 20mm / s-120mm / s is selected. When lychees are packaged in the packaging box of this embodiment, since the minimum oxygen concentration required for lychees to breathe is 5% to 8%, a breathable film with an air permeability of 100mm / s-220mm / s is selected.
