Description

Technical Field

[0001] This invention belongs to the field of product packaging technology, and in particular relates to a packaging box for uniform moisture control and preservation. Background Technology

[0002] Packaging boxes are widely used for storing and transporting goods. Currently, most packaging boxes simply place the product inside and then seal it. While this meets the needs of general applications, the transportation and storage of some agricultural products, such as fruits and vegetables, may require moisture control and preservation. Current technology for packaging such products often involves spraying moisture or preservatives onto the inside of the box or the product before sealing, but this results in poor uniformity and can negatively impact product quality in practice. Therefore, it is necessary to improve existing packaging boxes. Summary of the Invention

[0003] In view of this, the present invention aims to overcome the defects in the prior art and propose a packaging box for uniform moisture control and preservation.

[0004] To achieve the above objectives, the technical solution created by this invention is implemented as follows:

[0005] A uniform moisture-controlled and fresh-keeping packaging box includes a main body and a lid. The main body includes an inner box and an outer box. A top plate is provided between the top of the inner box side panel and the outer box side panel. The top plate includes a V-groove in the middle and wings on both sides. The bottom of the V-groove is provided with several drainage holes.

[0006] The cover includes a top cover and a connecting eave on the outer edge of the top cover, and a waterproof eave corresponding to the V-groove is provided on the lower surface of the top cover; several through holes are provided on the side plate of the inner box, and several rows of water storage holes are obliquely provided on the inner wall of the side plate of the outer box, and each row of water storage holes is connected by a water inlet channel.

[0007] The water inlet channels are arranged on the inner wall surface of the side panel of the outer box, and each water inlet channel is connected by several auxiliary channels. A water inlet component is provided between the lower edge of each through hole and the side panel of the outer box. The water inlet component is arranged at an angle, and its lower end is supported on the corresponding water inlet channel.

[0008] A water storage cavity is formed between the bottom plate of the outer box and the bottom plate of the inner box. The bottom plate of the inner box has several release holes. At the same time, a bottom support plate is provided on the upper side of the bottom plate of the inner box. The bottom support plate and the bottom plate of the inner box are supported by a support member. A gap is left between the bottom support plate and the side plate of the inner box, so that a channel for water to dissipate upward is formed between the bottom support plate and the inner box.

[0009] Furthermore, the length direction of the auxiliary trough is perpendicular to the length direction of the water intake trough.

[0010] Furthermore, the upper part of the inner box is provided with an inwardly inclined thickened area.

[0011] Furthermore, the portion of the lower surface of the top cover located inside the waterproof eaves forms a concave water collection hood, and the portion of the lower surface of the top cover located outside the waterproof eaves forms a support surface that cooperates with the main body. The plane of the support surface is lower than the top surface of the inner side of the water collection hood.

[0012] Furthermore, the water-guiding component is a rod or a plate.

[0013] Furthermore, the inner and outer surfaces of the inner box, outer box, and cover are all coated with a waterproof layer.

[0014] Furthermore, the water storage cave includes a concave portion and a water storage section on the lower side of the concave portion.

[0015] Compared with existing technologies, the present invention has the following advantages:

[0016] This invention features a rational structural design. By designing the main body of the packaging box as a double-layer structure with special water-guiding and water-storing structures in the interlayer, the moisture inside the packaging box can be evenly distributed, resulting in good humidification and humidity control effects. This effectively ensures the humidity control needs during the increasing storage and transportation of products. Attached Figure Description

Thus, features defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature. In the description of this invention, unless otherwise stated, "a plurality of" means two or more.

[0029] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art will understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0030] The invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0031] A type of packaging box for uniform moisture control and preservation, such as Figures 1 to 9As shown, the device includes a main body and a cover. The main body comprises an inner box 1 and an outer box 2. A top plate 5 is provided between the tops of the inner box side plate 3 and the outer box side plate 4. The top plate includes a V-groove 6 in the middle and wings 7 on both sides. The bottom of the V-groove has several drainage holes 8. The cover includes a top cover 9 and a connecting eave 10 on the outer edge of the top cover. A waterproof eave 11 corresponding to the V-groove is provided on the lower surface of the top cover. Several through holes 12 are opened on the side plate of the inner box. Several rows of water storage holes 13 are obliquely provided on the inner wall of the side plate of the outer box, and each row of water storage holes is connected by a water inlet trough 14. Specifically, the above-mentioned water storage holes include a concave portion 21 and a water storage portion 22 on the lower side of the concave portion.

[0032] The water inlet channels are arranged on the inner wall surface of the outer casing side panel, and each water inlet channel is connected by several auxiliary channels 15. A water inlet component 16 is provided between the lower edge of each through hole and the side panel of the outer casing. The water inlet component is arranged at an angle, and its lower end is supported on the corresponding (or adjacent) water inlet channel. The water inlet component serves as a functional component for capturing droplets and transporting droplets to the water inlet channel. At the same time, it can also effectively improve the structural stability between the inner and outer casings.

[0033] A water storage cavity 17 is formed between the bottom plate of the outer box and the bottom plate of the inner box, and several release holes 18 are provided on the bottom plate of the inner box. The water guide is a rod or plate, which can capture water droplets between the inner and outer boxes and let them flow to the water storage holes on the inner wall of the side plate of the outer box. After each water storage hole is full, the excess water will flow into the water storage cavity. The water released through the holes and release holes can make the inside of the packaging box form a near constant humidity state.

[0034] Meanwhile, a bottom support plate 19 is provided on the upper side of the bottom plate of the inner box. The bottom support plate is supported by the support member 20. A gap is left between the bottom support plate and the side plate of the inner box, so that a channel for moisture to dissipate upward is formed between the bottom support plate and the inner box. That is, when the packaged products are placed on the bottom support plate (several small holes can be opened on the bottom support plate as needed), the products at the bottom layer will not absorb all the moisture from the release holes. Instead, the moisture released through the release holes will be evenly distributed upward to the entire interior of the packaging box, making the humidity more uniform and stable, and providing long-term moisture control and freshness preservation.

[0035] Typically, the length of the auxiliary channel is perpendicular to the length of the water inlet channel. With the help of the auxiliary channel, the water flow or dripping water in the water inlet channel can be dispersed on the inner wall of the outer tank side panel, thus maximizing the retention of water from the water inlet to the outer tank side panel within the water storage cavity. In an optional embodiment, if the distance between the inner and outer tank side panels is small, an inwardly inclined thickened area 27 can be provided on the upper part of the inner tank. When setting the top plate, ample space is provided for the V-groove section to improve structural stability.

[0036] Typically, the inner and outer surfaces of the inner box, outer box, and lid are all coated with a waterproof layer. The portion of the lower surface of the lid inside the waterproof eaves forms a concave water collection hood 23, while the portion outside the waterproof eaves forms a support surface 24 that mates with the main body. The plane of the support surface is lower than the top surface of the inner side of the water collection hood. This water collection hood design aims to increase the gap between the lid and the product, preventing excessive moisture absorption by the topmost product. In an optional embodiment, the top surface of the inner side of the water collection hood has several grooves (the grooves approximate a T-shaped groove structure), including a main groove 25 and water-holding tanks 26 formed on both sides. When moisture is released into the water collection hood, some is allowed to remain in the water-holding tanks. The two ends of the arc-shaped main groove connect to the upper end of the water-holding tanks, allowing moisture absorbed on the surface of the main groove to flow into the water-holding tanks. This structural design ensures more even moisture release from the lid, resulting in more uniform humidity on the top of the product stored inside the packaging box.

[0037] To improve the uniformity of humidity control, in an optional embodiment, a humidifier can be placed between the inner and outer casings under necessary application conditions. The humidifier periodically draws water from the storage chamber (filled before sealing the packaging box) to humidify the items inside the packaging box. The water mist generated by the humidifier can circulate between the inner and outer casings and enter the inner casing through the release hole and through the perforation, ensuring higher humidity control and humidification requirements. Furthermore, the water mist circulating between the inner and outer casings is captured by the water guide and can flow into the water storage hole for temporary storage, thus creating a uniform humidification effect. The humidifier's on / off time can be controlled by a timer or wirelessly, which will not be elaborated further here. Humidifier selection can be made according to needs. For short-term transportation or storage, the humidifier can be powered by a rechargeable battery. If the packaging box is used as a carrier for long-term storage, the humidifier can be powered by an external power source. For example, a wire hole can be opened on the side panel of the packaging box, and the humidifier power supply wire can be connected to an external power source through the wire hole to achieve power connection (and control).

[0038] This invention features a rational structural design. By designing the main body of the packaging box as a double-layer structure with special water-guiding and water-storing structures in the interlayer, the moisture inside the packaging box can be evenly distributed, resulting in good humidification and humidity control effects. This effectively ensures the humidity control needs during the increasing storage and transportation of products.

[0039] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
