Description

Technical Field

[0001] This utility model belongs to the field of packaging box technology, and in particular relates to a food transportation packaging box with good moisture-proof effect. Background Technology

[0002] Food transport boxes are containers specifically designed to ensure the safety of food during transportation and storage. They are typically made of waterproof, moisture-proof, and pressure-resistant materials. Boxes used for transporting certain special foods may also incorporate temperature control features. These boxes prevent damage to food caused by external factors such as collisions, compression, or drops during transport, protecting food quality and improving logistics efficiency. Food transport boxes are widely used in fresh food cold chain transportation, bulk food logistics, and the transport of high-value specialty foods. Existing food transport packaging boxes are prone to aging and deformation due to long-term use, leading to seal failure. This makes it difficult to maintain a stable moisture-proof environment inside the box, which may cause food to become damp and spoil, resulting in economic losses. Most existing food transport packaging boxes only have simple physical partitions, which cannot effectively solve the problem of food odors crossing between different areas due to air circulation, affecting the original flavor and quality of the food. In the process of transporting multiple foods together, multiple independent packaging boxes are often needed to hold different types of food to prevent cross-contamination of flavors, which increases transportation costs. Utility Model Content

[0003] The purpose of this utility model is to solve the problems of existing food transport packaging boxes being prone to sealing failure after long-term use, causing food to become damp, and different types of food being easily mixed in flavor when packaged together, and to propose a food transport packaging box with good moisture-proof effect.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a food transport packaging box with good moisture-proof effect, comprising an outer shell, a top cover on the top of the outer shell, an inner liner inside the outer shell, a partition inside the inner liner, a sealing mechanism including a sealing strip disposed between the outer shell and the top cover, a pressing block disposed below the top cover, wherein when the top cover is connected to the outer shell, the pressing block continuously presses the sealing strip, and a separation mechanism including a filter tube embedded in the outer wall of the partition, through which the air flowing between the upper and lower layers of the inner liner is filtered.

[0005] Preferably, the sealing mechanism further includes: a limiting block, two limiting blocks symmetrically arranged in the groove at the top of the outer shell, and a travel groove, the travel groove being formed on the outer wall of the limiting block, a limiting rod passing through the travel groove, the two ends of the limiting rod being respectively connected to the corresponding positions of the inner wall of the groove at the top of the outer shell.

[0006] Preferably, it also includes a connecting plate, the two ends of which are rotatably connected to the top of the corresponding limiting block, and a rotating shaft, which passes through the top outer wall of the connecting plate, and a handwheel is rotatably connected to the top of the rotating shaft.

[0007] Preferably, it also includes a telescopic rod, the two ends of which are respectively connected to the corresponding positions of the bottom outer wall of the top cover and the top outer wall of the extrusion block, and a first spring, which is disposed outside the telescopic rod, and the two ends of the first spring are respectively connected to the corresponding positions of the bottom outer wall of the top cover and the top outer wall of the extrusion block.

[0008] Preferably, the separating mechanism further includes a fixing tube, which is embedded in the bottom of the partition, a connecting tube, which is connected to the top of the fixing tube, and a filter tube sleeved outside the top of the connecting tube. The connecting tube has a filter cavity through the plate.

[0009] Preferably, the method further includes a closed tube disposed inside a fixed tube, a movable plug whose outer wall is slidably connected to the inner wall of the closed tube, a plurality of vent holes being formed around the outer wall of the movable plug along the axis, and a fixed seat disposed below the movable plug. A second spring is provided between the fixed seat and the movable plug, and the two ends of the second spring are respectively connected to the corresponding positions of the bottom outer wall of the movable plug and the top outer wall of the fixed seat.

[0010] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are: 1. In this utility model, by setting a sealing mechanism, when the top cover is connected to the outer shell, the first spring continuously pushes the squeezing block downward through its own elastic force, so that the squeezing block continuously presses the sealing strip. When the sealing effect of the sealing strip weakens locally, self-compensation is performed to ensure the stability and continuity of the seal, thus ensuring the moisture-proof effect of the packaging box.

[0011] 2. In this utility model, by setting a dividing mechanism, the inner liner is divided into two parts, upper and lower. When different types of food need to be transported, different types of food can be placed in different areas. The filter material set in the filter chamber adsorbs and purifies the air flowing through, preventing different types of food from mixing flavors in the upper and lower areas. There is no need to use another packaging box, which improves the versatility and ease of use of the packaging box. Attached Figure Description

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0015] Please see Figures 1-5 This utility model provides a technical solution: a food transport packaging box with good moisture-proof effect, including an outer shell 1, a top cover 2 on the top of the outer shell 1, an inner liner 3 inside the outer shell 1, a partition 4 inside the inner liner 3, a sealing mechanism 5 including a sealing strip 507 between the outer shell 1 and the top cover 2, a pressing block 509 below the top cover 2, when the top cover 2 is connected to the outer shell 1, the pressing block 509 continuously presses the sealing strip 507, and a separation mechanism 6 including a filter tube 603 embedded in the outer wall of the partition 4, through which the air flowing between the upper and lower layers of the inner liner 3 is filtered.

[0016] The sealing mechanism 5 also includes a limiting block 501, two limiting blocks 501 are symmetrically arranged in the groove at the top of the outer shell 1, and a travel groove 502 is opened on the outer wall of the limiting block 501. A limiting rod 503 is passed through the travel groove 502, and the two ends of the limiting rod 503 are respectively connected to the corresponding positions of the inner wall of the groove at the top of the outer shell 1.

[0017] It also includes a connecting plate 504, with both ends of the connecting plate 504 rotatably connected to the top of the corresponding limiting block 501, and a rotating shaft 505, which passes through the top outer wall of the connecting plate 504. A handwheel 506 is rotatably connected to the top of the rotating shaft 505.

[0018] It also includes a telescopic rod 508, with its two ends connected to the corresponding positions of the bottom outer wall of the top cover 2 and the top outer wall of the extrusion block 509, and a first spring 510, which is located outside the telescopic rod 508 and has its two ends connected to the corresponding positions of the bottom outer wall of the top cover 2 and the top outer wall of the extrusion block 509.

[0019] Specifically, the bottom end of the rotating shaft 505 is rotatably connected to the connecting plate 504. The outer wall of the top end of the rotating shaft 505 is provided with an external thread, and the inner wall of the handwheel 506 is provided with an internal thread. The external thread on the outer wall of the top end of the rotating shaft 505 meshes with the internal thread on the inner wall of the handwheel 506. The bottom of the handwheel 506 is rotatably connected to the top outer wall of the top of the top cover 2. In the initial state, the limiting rod 503 is located at the bottom end of the stroke groove 502. At this time, the two adjacent limiting blocks 501 are close to each other. After the top cover 2 is placed on the top of the outer shell 1, the bottom end of the limiting block 501 is inserted into the groove on the top of the outer shell 1. When the handwheel 506 is rotated, the rotating shaft 505 moves relative to the outer shell 1. As the handwheel 506 descends, the limit rod 503 moves along the trajectory of the travel groove 502 from the bottom to the top of the travel groove 502. The two adjacent limit blocks 501 move away from each other. The cross-sectional shape of the limit block 501 is L-shaped. The shorter end of the L-shaped limit block 501 is stuck in the inner wall of the groove at the top of the outer shell 1, making the connection between the top cover 2 and the outer shell 1 more stable. At this time, the telescopic rod 508 retracts, and the first spring 510 is compressed. The first spring 510 pushes the squeezing block 509 downward through its elastic force, so that the squeezing block 509 continues to press the sealing strip 507 downward to ensure the sealing effect of the packaging box.

[0020] The separating mechanism 6 also includes a fixed tube 601, which is embedded in the bottom of the partition plate 4, a connecting tube 602, which is connected to the top of the fixed tube 601, and a filter tube 603 is sleeved on the outside of the top of the connecting tube 602. The connecting tube 602 has a filter chamber 604 through the plate.

[0021] It also includes a closed tube 605, which is located inside the fixed tube 601; a movable plug 606, the outer wall of which is slidably connected to the inner wall of the closed tube 605; a plurality of vent holes 607 are provided around the outer wall of the movable plug 606 along the axis; and a fixed seat 608, which is located below the movable plug 606. A second spring 609 is provided between the fixed seat 608 and the movable plug 606, and the two ends of the second spring 609 are respectively connected to the corresponding positions of the bottom outer wall of the movable plug 606 and the top outer wall of the fixed seat 608.

[0022] Specifically, when the packaging box is sealed, the air above the partition 4 will flow downwards due to pressure. As the air flows, it will carry the odor molecules of the food above the partition 4. The space from the top of the connecting pipe 602 to the top of the inner wall of the filter pipe 603 is set as the filter chamber 604. The filter chamber 604 is equipped with filter material. When the air flows through the filter chamber 604, the filter material intercepts the odor molecules in the air, thereby purifying the air. The purified air continues to move downwards. The air pressure pushes the moving plug 606 downwards, and the second spring 609 is compressed. The air leaves the sealing pipe 605 through the vent 607 of the moving plug 606 and enters the lower half of the inner liner 3 through the bottom opening of the fixed pipe 601. When the pressure in the upper and lower parts of the inner liner 3 reaches equilibrium, the second spring 609 is released. The second spring 609 pushes the moving plug 606 to reset, so that the internal space of the sealing pipe 605 is sealed and isolated from the internal space of the inner liner 3, preventing different types of food from mixing odors.

[0023] It should be noted that the filter material mentioned above is activated carbon. Activated carbon is a porous carbon material with huge adsorption capacity. It is made by high-temperature activation treatment. Due to its well-developed pore structure and huge specific surface area, it is widely used to adsorb impurities in gases and liquids. This part is well-known technology in the field and will not be described in detail here.

[0024] Working principle: When in use, the operator turns the handwheel 506 to bring the adjacent limit blocks 501 closer together to disconnect the top cover 2 from the outer shell 1. After removing the top cover 2, the operator takes out the partition 4 and pulls out the filter tube 603 to replace the filter material in the filter chamber 604. After the filter material is replaced, the operator inserts the filter tube 603 back into its original position. Then, the operator puts the food into the bottom of the inner liner 3, puts the partition 4 back in, and continues to put in the food. After all the food is placed, the operator puts the top cover 2 back on the top of the outer shell 1. Then, the operator turns the handwheel 506 in the opposite direction to make the top cover 2 and the outer shell 1 tightly connected, thereby sealing the packaging box and completing the food packaging.
