Abstract
Description
Technical Field
[0001] This application relates to the field of container technology, specifically to a plastic box with good air permeability. Background Technology
[0002] Currently, plastics are a class of materials made primarily of synthetic or natural polymer resins, with the addition of various additives. They possess ductility under certain temperature and pressure conditions and can be fixed in shape upon cooling. Plastic boxes are boxed packaging containers made of plastic materials. They can be transparent or opaque and are widely used in food packaging, daily necessities storage, and industrial parts storage. They offer advantages such as enhanced user experience, low density and light weight, ease of processing, durable packaging, moisture and water resistance, high toughness, strong transportation safety, and improved product quality.
[0003] However, existing plastic boxes have the following drawbacks: they are usually sealed structures, and some items (such as wood and plant materials, medical supplies, and textiles) may produce gases or moisture due to biological activities or physical changes during sealed storage. The accumulation of these gases or moisture may lead to a decline in the quality of the items or even damage. They cannot be ventilated regularly, making them inconvenient to use. Some boxes improve ventilation by setting up vents, but they cannot be sealed regularly. Prolonged ventilation can allow dust to enter and contaminate the items, and may even cause some items to age or be damaged more quickly, resulting in poor protection.
[0004] Therefore, how to improve existing plastic boxes to overcome the above-mentioned shortcomings is a problem that urgently needs to be solved by those skilled in the art. Summary of the Invention
[0005] One object of this application is to provide a breathable plastic box that is ventilated and sealed, provides good protection, and is easy to use.

[0024] Reference Figure 1-2One embodiment of this application provides a breathable plastic box, including a box body 1, a lid 2, a connecting component 3, a first sealing component 4, a second sealing component 5, and a control component 6. The lid 2 is detachably connected to the opening 16 of the box body 1 via the connecting component 3. A plurality of first ventilation openings 11 are formed through the bottom of the box body 1, a plurality of second ventilation openings 12 are formed through the side wall of the box body 1, and a plurality of third ventilation openings 21 are formed through the lid 2. The first sealing component 4 is movably disposed on the box body 1 and is used to control the opening and closing of the first ventilation openings 11 and the second ventilation openings 12. The second sealing component 5 is movably disposed on the lid 2 and is used to control the opening and closing of the third ventilation openings 21. The control component 6 is disposed between the box body 1 and the lid 2 and is used to control the movement of the first sealing component 4 and the second sealing component 5. The connecting component 3 enables the detachable connection between the box body 1 and the lid 2, allowing items to be stored or removed from the box body 1, providing basic protection and ease of use. Simultaneously, the control component 6 controls the movement of the first sealing component 4 and the second sealing component 5, thereby controlling the opening of the first ventilation port 11 and the second ventilation port 12 on the box body 1 and the third ventilation port 21 on the lid 2 for ventilation or sealing during use. This allows for quick changes in the storage environment according to storage needs, enhancing convenience and further improving the protective effect. Therefore, this breathable plastic box provides both ventilation and sealing, offering good protection and ease of use.
[0025] Reference Figure 1-5In some embodiments of this application, a first sliding groove 13 is formed at the four corners of the box body 1, and a second sliding groove 22 is formed at the four corners of the cover body 2. The control component 6 includes a first control rod 61, a second control rod 62, an elastic element 63, and a pushing element 64. The first control rod 61 is slidably disposed in the first sliding groove 13 and connected to the first sealing component 4. The second control rod 62 is slidably disposed in the second sliding groove 22 and connected to the second sealing component 5. The elastic element 63 is disposed in the first sliding groove 13 and is used to force the first control rod 61 to push the second control rod 62 to move until the first sealing component 4 and the second sealing component 5 are sealed. One end of the pushing element 64 is disposed on the second control rod 62 and the other end extends to the outside of the cover body 2. By setting the elastic element 63 in conjunction with the pushing element 64 to control the movement of the first control rod 61 and the second control rod 62, the movement of the first sealing component 4 and the second sealing component 5 is controlled. In use, the second control lever 62 is first inserted into the first slide groove 13 to position the cover 2 and the box 1. The cover 2 is then connected to the opening 16 of the box 1 via the connecting assembly 3. When the first vent 11, the second vent 12, and the third vent 21 are opened, the first sealing assembly 4 and the second sealing assembly 5 are opened by the pusher 64, and the elastic element 63 deforms. When the first vent 11, the second vent 12, and the third vent 21 are opened, the pusher 64 is released, the elastic element 63 returns to its original shape, and forces the first control lever 61 to push the second control lever 62 to move until the first sealing assembly 4 and the second sealing assembly 5 are sealed. It should be noted that the elastic element 63 is a coil spring, a leaf spring, etc., and its own design and installation method are existing technologies, which will not be described in detail here.
[0026] Reference Figure 1-5 In some embodiments of this application, the connecting component 3 is a connecting buckle structure, comprising multiple sub-buckles 31 and female buckles 32. The multiple sub-buckles 31 are disposed at the four corners of the cover 2; the multiple female buckles 32 are disposed at the four corners of the box 1 and are used to connect the sub-buckles 31 or the pusher 64; and when the female buckle 32 connects to and pushes the pusher 64, the female buckle 32 connects to the sub-buckles 31. This realizes the detachable connection between the box 1 and the cover 2, while controlling and restricting the movement of the pusher 64. When the female buckle 32 only connects to the sub-buckles 31, the connection between the box 1 and the cover 2 is realized; when the female buckle 32 pushes the pusher 64, it is necessary to simultaneously operate two female buckles 32 on opposite corners of the box 1, and then operate two female buckles 32 on the other opposite corner of the box 1, so that after controlling the pusher 64 to push, the female buckles 31 restrict the movement of the pusher 64, locking the first sealing component 4 and the second sealing component 5 in the open state. It should be noted that the connecting buckle structure itself and the installation method are existing technologies, and will not be described in detail here.
