Description

Technical Field

[0001] This utility model relates to the field of packaging box technology, specifically to a waterproof packaging color box. Background Technology

[0002] Packaging boxes are now a common protective structure used on the outside of products. They effectively hold the products, preventing them from being subjected to additional collisions during transportation and movement. They also effectively prevent debris and water from contaminating the products.

[0003] A waterproof printed packaging box and its manufacturing process are disclosed in CN119079306A. The box includes a box body with a first cover hinged to its top, and a waterproof block is provided on the first cover. A fastening component includes a protrusion at the bottom of the first cover, a limiting groove on the side surface of the protrusion, a groove on the top of the box body for the protrusion to insert into, and a support member installed on the side surface of the box body. The fastening component design improves the efficiency of the first cover closing onto the box body. The addition of a protective frame helps to increase the protection of the desiccant box, preventing the placed product from colliding with the desiccant box and increasing safety during use. This process aims to improve the efficiency of packaging box manufacturing, increase waterproof performance, and extend service life. It has advantages such as high production efficiency, good waterproof performance, and long service life.

[0004] However, when the above technology is used for connection, it only uses a fastening component on one side for compression and fixation, while the rotating shaft on the other side lacks a compression and fixation structure, which can easily cause liquid to flow in from the gap. At the same time, the top cover structure of the device is also relatively simple. Once liquid enters the interior, there is no structure to block the liquid, which can easily cause the liquid to flow freely and contaminate the product. Utility Model Content

[0005] Therefore, this utility model provides a waterproof packaging box to solve the problems in the prior art where insufficient sealing and fixing easily leads to poor waterproofing, and the lack of liquid restriction in the internal structure of the packaging box causes liquid to flow freely and contaminate the product.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A waterproof packaging box includes an outer box, an inner box, and a receiving box, characterized in that the inner box is nested inside the outer box, the inner box contains a plurality of receiving boxes, and a cover plate is fixedly connected to the top of the inner box.

[0008] The top outer wall of the inner box is provided with a circumferential slot, and the inner sides of the inner box are provided with symmetrical sliding grooves.

[0009] The top of the inner side of the outer box is fitted with a snap-fit ​​strip, the position of which corresponds to the slot.

[0010] Each of the containers has a connecting block fixedly connected to its bottom, and a sealing ring is arranged around the bottom of the outer box. A rectangular hole corresponding to the outer wall of the connecting block is opened at the center of the sealing ring.

[0011] Furthermore, the top edge of the inner wall of the snap-fit ​​strip slopes towards the bottom, and a rubber sealing strip is provided inside the snap-fit ​​groove.

[0012] Furthermore, the dimensions of the cover plate correspond to the dimensions of the outer wall of the outer box, and the bottom edge of the cover plate fits into the top of the outer box.

[0013] Furthermore, the top of the receiving box is provided with a receiving groove, and the internal dimensions of the receiving groove correspond to the outer wall dimensions of the connecting block. The top opening size of the receiving groove is larger than the bottom size of the receiving groove.

[0014] Furthermore, a sealing block is fixedly connected to the center of the cover plate, and the size of the sealing block corresponds to the size of the connecting block.

[0015] Furthermore, the inner top of the receiving box is fitted with the outer wall of the sealing block, and both the outer and inner boxes are provided with waterproof membranes.

[0016] Furthermore, the inner box has teeth that are inclined upwards inside the sliding grooves on both sides, and snap-fit ​​blocks are installed on both sides of the outer wall of the receiving box at positions corresponding to the sliding grooves.

[0017] Furthermore, the top edge of the snap-fit ​​block is inclined to the bottom, and the snap-fit ​​block engages with the teeth inside the sliding groove.

[0018] This utility model has the following advantages:

[0019] 1. Multiple containers are assembled together to achieve a closed combination. Then, the snap-fit ​​blocks on both sides of the container correspond to the sliding grooves on both sides of the inner box, allowing the container to be inserted into the inner box. The top sealing block fits and seals with the top of the container, thus sealing the multiple containers. The inner box is then nested with the outer box, causing the sealing ring at the bottom of the outer box to fit and press against the bottom of the inner box, thus sealing the inside of the inner box. The snap-fit ​​strip and the snap-fit ​​groove engage to fix the inner and outer boxes, and also ensure that the top edge of the outer box fits tightly against the cover plate to achieve a seal, effectively achieving waterproofing and preventing liquid from entering.

[0020] 2. Due to the interlocking of the inner and outer boxes, the liquid moves through the gap between them. Simultaneously, the inner box's obstruction prevents the liquid from immediately contacting the product upon entering the outer box. The liquid must then travel along the inner wall of the inner box to the top of the container, further restricting its movement. This ensures that the liquid reaches the interior of the container before finally contacting the product, effectively limiting and blocking the liquid and preventing it from flowing and contaminating the product. Furthermore, the close-fitting and sealed arrangement of multiple containers isolates them from each other, effectively preventing contamination of the containers and further protecting the product.

[0029] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0030] refer to Figure 1-5 As shown, a waterproof packaging box includes an outer box 1, an inner box 2, and a receiving box 3. The inner box 2 is nested inside the outer box 1, and multiple receiving boxes 3 are disposed inside the inner box 2. A cover plate 4 is fixedly connected to the top of the inner box 2. A groove 201 is circumferentially formed on the top outer wall of the inner box 2, and sliding grooves 202 are symmetrically arranged on both sides of the inner box 2. A snap-fit ​​strip 101 is circumferentially installed on the top of the inner box 1, with the snap-fit ​​strip 101 corresponding to the groove 201. A connecting block 301 is fixedly connected to the bottom of each receiving box 3, and a sealing ring 102 is circumferentially formed at the bottom of the inner side of the outer box 1. A rectangular hole corresponding to the outer wall of the connecting block 301 is formed at the center of the sealing ring 102. Products are placed into the receiving boxes 3, and then the multiple receiving boxes 3 are assembled together, so that the connecting blocks 301 at the top and bottom of the different receiving boxes 3 snap together, thereby achieving a sealed combination.

[0031] refer to Figure 1 , Figure 2 As shown, the top edge of the inner wall of the snap-fit ​​strip 101 slopes downwards, and a rubber sealing strip is provided inside the snap-fit ​​groove 201. The sliding grooves 202 on both sides of the inner box 2 are provided with teeth that slope upwards. Snap-fit ​​blocks 302 are installed on both sides of the outer wall of the receiving box 3 at positions corresponding to the sliding grooves 202. The top edge of the snap-fit ​​blocks 302 slopes downwards, and the snap-fit ​​blocks 302 and the teeth inside the sliding grooves 202 engage with each other, connecting the inner box 2 and the outer box 1. This causes the sealing ring 102 at the bottom of the outer box 1 to fit and press against the bottom of the inner box 2, thus sealing the inside of the inner box 2. Simultaneously, because the snap-fit ​​strip 101 is provided on the top side wall of the outer box 1, when the inner box 2 and the outer box 1 are connected, the snap-fit ​​strip 101 engages with the snap-fit ​​groove 201, fixing the inner box 2 and the outer box 1. It also ensures that the top edge of the outer box 1 fits tightly against the cover plate 4, effectively achieving waterproofing and preventing liquid ingress.

[0032] refer to Figure 3 , Figure 4As shown, the dimensions of the cover plate 4 correspond to the outer wall dimensions of the outer box 1. The bottom edge of the cover plate 4 fits snugly against the top of the outer box 1. The top of the receiving box 3 has a receiving groove, and the internal dimensions of the receiving groove correspond to the outer wall dimensions of the connecting block 301. The top opening of the receiving groove is larger than the bottom opening. A sealing block 401 is fixedly connected to the center of the inside of the cover plate 4. The dimensions of the sealing block 401 correspond to the dimensions of the connecting block 301. The top of the inside of the receiving box 3 fits into the outer wall of the sealing block 401. Both the outer box 1 and the inner box 2 have... A waterproof membrane is used to assemble multiple containers 3 together, so that the connecting blocks 301 at the top and bottom of different containers 3 interlock with each other, thereby achieving mutual combination and sealing. Due to the obstruction of the inner box 2, even if liquid enters, it can only move through the gap between the outer box 1 and the inner box 2. At the same time, the obstruction of the inner box 2 also prevents the liquid from contacting the product as soon as it enters. The liquid needs to move along the inner wall of the inner box 2 to the top of the container 3, further restricting the movement of the liquid. Thus, the liquid can only finally come into contact with the product after reaching the inside of the container 3.

[0033] Working principle: During use, products can be easily placed into the housing box 3, and then multiple housing boxes 3 can be assembled together. The connecting blocks 301 at the top and bottom of different housing boxes 3 interlock, thereby achieving a sealed combination. Then, the interlocking blocks 302 on both sides of the housing box 3 correspond to the sliding grooves 202 on both sides of the inner box 2, allowing the housing box 3 to be inserted into the inner box 2. At the same time, the teeth inside the sliding grooves 202 interlock with the interlocking blocks 302, preventing the housing box 3 from falling out. The top sealing block 401 fits snugly against the top of the housing box 3 for a seal. This achieves the sealing of multiple containers 3, and then the inner container 2 and the outer container 1 are interlocked, so that the sealing ring 102 at the bottom of the outer container 1 and the bottom of the inner container 2 are pressed together, thereby sealing the inside of the inner container 2. At the same time, since the top side wall of the outer container 1 is provided with a snap-fit ​​strip 101, when the inner container 2 and the outer container 1 are interlocked, the snap-fit ​​strip 101 and the snap-fit ​​groove 201 can be interlocked to fix the inner container 2 and the outer container 1. It can also make the top edge of the outer container 1 fit tightly with the cover plate 4 to achieve a seal, effectively achieving waterproofing and preventing liquid from entering.

[0034] During use, even if liquid enters, it is blocked by the inner box 2, causing it to move only through the gap between the outer box 1 and the inner box 2. The inner box 2 also prevents the liquid from immediately contacting the product; instead, it must move along the inner wall of the inner box 2 to the top of the container 3, further restricting its movement. This ensures the liquid reaches the interior of the container 3 before finally contacting the product, effectively limiting and blocking the liquid and preventing it from flowing and contaminating the product. Furthermore, the multiple containers 3 are tightly sealed together, isolating each other and effectively preventing the product inside each container from being contaminated, further protecting the product.

[0035] Although the present invention has been described in detail above with general descriptions and specific embodiments, some modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, all such modifications or improvements made without departing from the spirit of the present invention fall within the scope of protection claimed by the present invention.
