[0002] Aseptic double-layer packaging boxes are a packaging solution designed to keep items preserved, delivered, and used in a sterile environment. The design of these boxes is primarily based on the needs of aseptic packaging technology, especially in the medical, food, and other industries with strict requirements for microbial contamination.
[0003] Some existing aseptic packaging boxes have failed to adequately consider the requirements for sterility and airtightness in their material selection. They may use single-layer materials or combinations of materials that are not good at blocking external microorganisms and maintaining an internal sterile environment. In particular, under extreme conditions such as humidity, high temperature or high pressure, the performance of these materials may further deteriorate, leading to the destruction of the sterile state. Utility Model Content
[0004] The technical problem to be solved by this utility model is that the sealing method of the packaging box in the prior art may be too simple, such as relying only on pressing or pasting to seal. These methods are easily affected by the external environment during long-term storage or transportation, resulting in a decrease in sealing performance. Therefore, we propose a sterile double-layer packaging box.
[0005] To achieve the above objectives, this application adopts the following technical solution: a sterile double-layer packaging box, comprising a first sterile box, a second sterile box slidably connected inside the first sterile box, a pull-out cabinet slidably connected inside the second sterile box, a handle fixedly connected to the top of the second sterile box, adjustment grooves on both sides of the front end of the first sterile box, adjustment blocks slidably connected inside the adjustment grooves, a through groove on the side of the adjustment groove near the second sterile box, an insert fixedly connected to the side of the adjustment block near the second sterile box, straight grooves on both sides of the second sterile box, and slots at the front end of the straight grooves.

[0011] Preferably, guide grooves are provided on both sides of the interior of the second sterile box, and guide blocks are fixedly connected to both sides of the pull-out cabinet. The surface of the guide block is slidably connected to the interior of the guide groove.
[0012] The technical effects and advantages of this utility model are as follows:
[0013] In this invention, the worker pushes the adjusting block into the adjusting groove, causing the adjusting block to move the insert block and release the limiting position between the insert block and the slot.

[0020] The present invention will now be described in further detail with reference to the accompanying drawings and preferred embodiments. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.
[0021] Reference Figures 1-5 As shown, this utility model provides a technical solution: a sterile double-layer packaging box, including a first sterile box 1, a second sterile box 2 slidably connected inside the first sterile box 1, a pull-out cabinet 3 slidably connected inside the second sterile box 2, a handle 4 fixedly connected to the top of the second sterile box 2, adjustment grooves 5 on both sides of the front end of the first sterile box 1, adjustment blocks 6 slidably connected inside the adjustment grooves 5, a through groove 7 on the side of the adjustment groove 5 near the second sterile box 2, an insert block 8 fixedly connected to the side of the adjustment block 6 near the second sterile box 2, straight grooves 9 on both sides of the second sterile box 2, and a slot 10 at the front end of the straight groove 9. When an operator pushes the adjustment block 6 into the adjustment groove 5, the adjustment block 6 moves the insert block 8 and releases the limit between the insert block 8 and the slot 10. The operator then pulls the second sterile box 2 upwards, causing the second sterile box 2 to be pulled out, and the pull-out cabinet 3 to be pulled out, exposing the space inside the pull-out cabinet 3. Through the above settings, the contents stored inside the pull-out cabinet 3 are effectively protected and sealed.
[0022] Reference Figure 4 As shown in this embodiment: both ends of the adjusting groove 5 are provided with sliding grooves 11, and both ends of the adjusting block 6 are fixedly connected with sliding blocks 12. The surface of the sliding block 12 is slidably connected to the inside of the sliding groove 11. When the operator moves the adjusting block 6, the adjusting block 6 drives the sliding block 12 to slide inside the sliding groove 11. Through the above settings, the adjusting block 6 can be more stable during movement, and it is not easy to shake or deviate, ensuring the accuracy and reliability of the adjusting block 6 during movement. At the same time, when the sliding block 12 slides inside the sliding groove 11, it can also play a certain guiding role, making the movement trajectory of the adjusting block 6 clearer, further improving the accuracy and convenience of operation.
[0023] Reference Figure 2 and Figure 4 As shown in this embodiment: the size of the plug 8 is adapted to the size of the slot 10, and the surface of the plug 8 is inserted into the interior of the slot 10. By adapting the size of the plug 8 to the size of the slot 10, the plug 8 can be stably inserted into the slot 10 without easily shaking or falling off. When the adjusting block 6 moves to the outside of the adjusting groove 5, the plug 8 will enter the interior of the slot 10, thus achieving a connection and fixation function. This insertion method is not only simple and convenient, but also greatly improves the stability and firmness of the structure.
[0024] Reference Figure 4As shown in this embodiment: the rear end of the adjusting block 6 is fixedly connected to a storage spring 13, and the rear end of the storage spring 13 is fixedly connected to the rear end inside the adjusting groove 5. When the operator pushes the adjusting block 6 into the adjusting groove 5, the adjusting block 6 compresses the storage spring 13 to store force, and drives the insert 8 to release the limit between itself and the slot 10. After the operator adjusts the second sterile box 2 to the appropriate position, the insert 8 is aligned with the slot 10 and released. Under the action of the rebound force of the storage spring 13, the insert 8 is quickly inserted into the slot 10 to fix the second sterile box 2.
[0025] Reference Figure 3 As shown in this embodiment: The first sterile box 1 has sliding grooves 14 on both sides inside; the second sterile box 2 has sliders 15 fixedly connected to both sides. The surface of the sliders 15 is slidably connected to the inside of the sliding grooves 14. When the operator moves the second sterile box 2, the second sterile box 2 drives the sliders 15 to slide inside the sliding grooves 14. This design not only makes the movement of the second sterile box 2 smoother and reduces friction and resistance, but also improves the flexibility and durability of the overall structure. Furthermore, the sliding connection design between the sliders 15 and the sliding grooves 14 effectively limits the movement range of the second sterile box 2, preventing excessive movement or displacement from the predetermined position, thereby ensuring the stability and safety of the equipment.
[0026] Reference Figure 3 As shown in this embodiment: both sides of the bottom of the first sterile box 1 are fixedly connected to return springs 16, and the top of the return springs 16 is fixedly connected to push plates 17. When the staff pushes the second sterile box 2 into the first sterile box 1, the second sterile box 2 pushes the push plates 17 to compress the return springs 16 and store force. When the staff releases the limit of the second sterile box 2, the push plates 17 quickly rebound under the action of the rebound force of the return springs 16, thereby pushing the second sterile box 2 to move outward, realizing the rapid release and reset of the second sterile box 2. This design not only improves the operating efficiency of the equipment, but also makes the movement and fixation of the second sterile box 2 more convenient and reliable.
[0027] Reference Figure 3 and Figure 5As shown in this embodiment: guide grooves 19 are provided on both sides of the interior of the second sterile box 2, and guide blocks 18 are fixedly connected to both sides of the pull-out cabinet 3. The surface of the guide block 18 is slidably connected to the interior of the guide groove 19. When the operator pulls out or inserts the pull-out cabinet 3, the pull-out cabinet 3 drives the guide groove 19 to slide inside the guide groove 19. Through the above settings, not only is the operation of pulling out or inserting the pull-out cabinet 3 smoother and the jamming phenomenon reduced, but the overall operational convenience and usage efficiency of the structure are also improved. At the same time, the sliding connection design between the guide block 18 and the guide groove 19 can also effectively disperse the pressure generated during the movement of the pull-out cabinet 3 and extend the service life of the equipment.
[0028] Working principle: The operator pushes the adjusting block 6 into the adjusting groove 5, causing the adjusting block 6 to move the insert block 8 and release the limiting position between the insert block 8 and the slot 10. The operator then pulls the second sterile box 2 upwards, causing it to extend and the pull-out cabinet 3 to expose its interior space. This design effectively protects and seals the items stored inside the pull-out cabinet 3. When the operator moves the adjusting block 6, it causes the sliding block 12 to slide within the sliding groove 11. This design makes the adjusting block 6 more stable during movement, preventing wobbling or deviation, and ensuring the accuracy and reliability of its movement. Simultaneously, the sliding block 12 slides within the sliding groove 11. When sliding internally, it also serves as a guide, making the movement trajectory of the adjusting block 6 clearer and further improving the accuracy and convenience of operation. By matching the size of the insert 8 with the size of the slot 10, the insert 8 can be stably inserted into the slot 10 without easily shaking or falling out. When the adjusting block 6 moves outward from the adjusting groove 5, the insert 8 will follow into the slot 10, achieving a connection and fixation function. This insertion method is not only simple and convenient but also greatly improves the stability and robustness of the structure. When the operator pushes the adjusting block 6 into the adjusting groove 5, the adjusting block 6 compresses the energy storage spring 13 to store energy, and drives the insert 8 to release the limit between itself and the slot 10. When the operator adjusts the second... After positioning the sterile box 2, align the insert 8 with the slot 10 and release it. Under the rebound force of the storage spring 13, the insert 8 quickly inserts into the slot 10, securing the second sterile box 2. When the operator moves the second sterile box 2, the second sterile box 2 drives the slider 15 to slide inside the groove 14. This design not only makes the movement of the second sterile box 2 smoother and reduces friction and resistance, but also improves the overall flexibility and durability of the structure. Simultaneously, the sliding connection design between the slider 15 and the groove 14 effectively limits the movement range of the second sterile box 2, preventing excessive movement or displacement from the predetermined position, thus ensuring the stability and safety of the equipment. This allows the operator to insert the first sterile box 1 into the... When the second sterile box 2 is pushed, it compresses the return spring 16 by pushing the push plate 17. When the operator releases the limit of the second sterile box 2, the push plate 17 quickly rebounds under the rebound force of the return spring 16, thereby pushing the second sterile box 2 outward, realizing the rapid release and reset of the second sterile box 2. This design not only improves the operating efficiency of the equipment, but also makes the movement and fixation of the second sterile box 2 more convenient and reliable. When the operator pulls out or inserts the pull cabinet 3, the pull cabinet 3 drives the guide groove 19 to slide inside the guide groove 19. Through the above settings, not only is the operation of pulling out or inserting the pull cabinet 3 smoother and the jamming phenomenon reduced, but the overall operational convenience and usage efficiency of the structure are also improved.Meanwhile, the sliding connection design between the guide block 18 and the guide groove 19 can effectively disperse the pressure generated during the movement of the pull-out cabinet 3, extending the service life of the equipment.
