Description
Technical Field
[0001] This utility model belongs to the field of laboratory equipment technology, specifically a sterile container lid with side-mounted support legs. Background Technology
[0002] Maintaining a sterile environment is crucial when conducting experiments within a laminar flow hood. As key equipment for storing and using sterile items, the design of the lids of sterile containers plays a vital role in maintaining this sterile environment.
[0003] Currently, the lids of sterile containers used in laminar flow hoods are usually round. In actual operation, to reduce contamination, operators are accustomed to placing the lids on their sides.
[0004] However, round lids are unstable when placed on their side and are prone to rolling off. There is an urgent need for a new lid design to solve the problem of round aseptic container lids rolling off their side. In addition, traditional support legs cannot be separated from the lid body for storage, which increases the overall space occupied. Utility Model Content
[0005] To address the shortcomings of existing technologies and solve the problem mentioned in the background art—namely, the poor stability of round lids when placed on their side, which easily rolls off—once the lid rolls into a non-sterile area, greatly increasing the risk of contamination of the contents of the container upon reuse, thus affecting the accuracy and reliability of experimental results, this problem has persisted in long-term experimental operations, causing considerable inconvenience to researchers and experimental operators. There is an urgent need for a new lid design to solve the problem of round sterile container lids easily rolling off their side. Furthermore, traditional support legs cannot be separated from the lid body for storage, thus increasing the overall space occupied. This utility model proposes a sterile container lid with side-mounted support legs.
[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: The sterile container lid with side-mounted support legs of this utility model includes a first circular lid body, characterized in that: a first side-mounted support leg is evenly arranged on the lower left and right edges of the first circular lid body, the angle between two adjacent first side-mounted support legs is 60 degrees, the first side-mounted support leg includes a second side-mounted support leg, an anti-slip pad is fixedly connected to the lower part of the second side-mounted support leg, an insertion block is fixedly connected to the upper part of the second side-mounted support leg, a T-shaped circular groove is opened on the side of the two insertion blocks that are far apart, a snap-fit block is slidably connected to the inner wall of the T-shaped circular groove, and a limit plate is fixedly connected to the opposite side of the two snap-fit blocks.
[0007] Preferably, springs are fixedly connected to the opposite surfaces of the two limiting plates, the outer wall of the limiting plate is slidably connected to the inner wall of the T-shaped groove, and the other end of the spring is fixedly connected to the inner wall of the T-shaped groove.
[0008] Preferably, a first connecting block is slidably connected to the outer wall of the plug-in block, the first connecting block includes two second connecting blocks, and a plug-in groove is provided below the second connecting block.
[0009] Preferably, a circular hole is provided on the inner wall of the insertion slot at the position corresponding to the snap-fit block.
[0010] Preferably, the inner wall of the insertion slot is slidably connected to the outer wall of the insertion block, and the inner wall of the circular hole is slidably connected to the outer wall of the snap-fit block.
[0011] Preferably, a first circular cover is fixedly connected above the two second connecting blocks, the first circular cover including a second circular cover, and the second circular cover having wavy air holes.
[0012] Preferably, a sealing gasket is provided on the inner surface of the second circular cover.
[0013] The beneficial effects of this utility model are as follows: 1. The sterile container lid with side-mounting feet described in this utility model features a first side-mounting foot with a 60-degree angle on the edge of the first circular lid. This ensures the lid is stably placed in the laminar flow hood when tilted, greatly reducing the risk of the lid rolling off and effectively minimizing the possibility of contamination of the contents due to the lid falling off. This improves the safety and reliability of experimental operations. The anti-slip pad at the bottom of the second side-mounting foot further enhances the stability of the lid when tilted. Even with slight vibrations or accidental contact within the laminar flow hood, the lid is not easily slipped. The anti-slip pad is made of silicone to increase friction with the laminar flow hood surface. To further prevent the lid from sliding, the wave-shaped vent design on the No. 2 circular lid extends the path for air to enter the container, effectively blocking external dust, bacteria, and other impurities. While meeting the ventilation requirements, it further enhances the container's dustproof and antibacterial effects. The sealing gasket on the inner surface of the No. 2 circular lid effectively improves the sealing performance between the lid and the sterile container, better maintaining the sterile state inside the container and providing a more reliable guarantee for experiments. The No. 1 side support foot is integrally molded with the No. 1 circular lid and is made of medical-grade plastic, ensuring the overall strength and biocompatibility of the lid and preventing pollution of the experimental environment.
[0014] 2. The sterile container lid with a side-mounted support leg described in this utility model allows for disassembly by pressing the locking block, which slides the locking block, the limiting plate, the T-shaped groove, and the round hole. The locking block disengages from the round hole and is placed in the inner wall of the T-shaped groove. Then, the insertion block is pulled out from the inner wall of the insertion groove to complete the disassembly. During installation, the locking block is pressed and slid into the inner wall of the T-shaped groove. Then, the insertion block is inserted into the inner wall of the insertion groove. When the round hole corresponds to the locking block, the spring pushes the limiting plate to slide through its elastic force. The limiting plate pushes the locking block to engage in the inner wall of the round hole and fix it in place, thus completing the installation. In the non-use state, the detachable first side-mounted support leg can be detached from the first connecting block and separated from the first round lid body for storage, reducing the overall space occupied. For example, in small spaces such as laboratory sterilizers and medical carts, the separated parts can be stacked more flexibly. During long-distance transportation, the disassembled state reduces the risk of the support leg breaking due to external impact, increases packaging density, and saves logistics costs.

[0018] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0019] like Figures 1 to 4As shown in the embodiment of this utility model, a sterile container lid with side-mounted supports includes a first circular lid body 3. First side-mounted supports 1 are evenly arranged on the lower left and right edges of the first circular lid body 3, with an angle of 60 degrees between adjacent first side-mounted supports 1. Each first side-mounted support 1 includes a second side-mounted support 11. An anti-slip pad 12 is fixedly connected to the lower part of the second side-mounted support 11, and a connecting block 13 is fixedly connected to the upper part of the second side-mounted support 11. T-shaped grooves 14 are formed on the opposite sides of the two connecting blocks 13. A locking block 15 is slidably connected to the inner wall of the T-shaped groove 14. The two locking blocks 15... 5. Limiting plates 16 are fixedly connected to each other on opposite sides. Springs 17 are fixedly connected to the opposite sides of the two limiting plates 16. The outer wall of the limiting plate 16 is slidably connected to the inner wall of the T-shaped circular groove 14. The other end of the spring 17 is fixedly connected to the inner wall of the T-shaped circular groove 14. A first connecting block 2 is slidably connected to the outer wall of the plug-in block 13. The first connecting block 2 includes two second connecting blocks 21. A plug-in groove 22 is opened below the second connecting block 21. A circular hole 23 is opened on the inner wall of the plug-in groove 22 at the corresponding position of the snap-in block 15. The inner wall of the plug-in groove 22 is slidably connected to the outer wall of the plug-in block 13. The inner wall of the circular hole 23 is slidably connected to the outer wall of the snap-in block 15.
[0020] The first side support leg 1 can be quickly detached from the first connecting block 2. In use, by pressing the snap-fit block 15, the snap-fit block 15, the limiting plate 16, the T-shaped circular groove 14, and the circular hole 23 slide. The snap-fit block 15 disengages from the circular hole 23 and is placed in the inner wall of the T-shaped circular groove 14. Then, the insertion block 13 is pulled out from the inner wall of the insertion groove 22 to complete the disassembly. In installation, by pressing the snap-fit block 15, it slides into the inner wall of the T-shaped circular groove 14. Then, the insertion block 13 is inserted into the inner wall of the insertion groove 22. When it slides to the position where the circular hole 23 corresponds to the snap-fit block 15, the spring 17 pushes the limiting plate 16 to slide through the elastic force. The limiting plate 16 pushes the snap-fit block 15 into the inner wall of the circular hole 23 and fixes it in place. The installation is then completed. In the non-use state, the detachable first side support leg 1 can be detached from the first connecting block 2 and separated from the first circular cover 3 for storage, reducing the overall space occupied, increasing the packaging density, and saving logistics costs.
[0021] like Figures 4 to 5 As shown, a first circular cover 3 is fixedly connected above the two second connecting blocks 21. The first circular cover 3 includes a second circular cover 31. The second circular cover 31 has a wavy air hole 32 and a sealing gasket 33 is provided on the inner surface of the second circular cover 31.
[0022] When it is necessary to open the sterile container, remove the circular cap 3 from the container and place the circular cap 3 on its side on the table inside the laminar flow hood. The first side support 1 supports the cap, and the anti-slip pad 12 contacts the table surface to ensure that the circular cap 3 is placed stably. At this time, the wavy vent 32 allows air to pass through while effectively blocking external impurities from entering.
[0023] After the operation is completed, pick up the first circular cap 3 and place it on the sterile container. The sealing gasket 33 on the inner surface of the second circular cap 31 fits tightly with the container opening to form a good seal and prevent bacteria from entering the container.
[0024] Working principle: The first side support leg 1 can be quickly detached from the first connecting block 2. During use, by pressing the locking block 15, the locking block 15, the limiting plate 16, the T-shaped circular groove 14, and the circular hole 23 slide. The locking block 15 disengages from the circular hole 23 and is placed in the inner wall of the T-shaped circular groove 14. Then, the insertion block 13 is pulled out from the inner wall of the insertion groove 22 to complete the disassembly. During installation, by pressing the locking block 15, it slides into the inner wall of the T-shaped circular groove 14. Then, the insertion block 13 is inserted into the inner wall of the insertion groove 22. When it slides to the position where the circular hole 23 corresponds to the locking block 15, the spring 17 pushes the limiting plate 16 to slide through the elastic force. The limiting plate 16 pushes the locking block 15 into the inner wall of the circular hole 23 and fixes it, thus completing the installation. In the non-use state, the detachable first side support leg 1 can be detached from the first connecting block 2 and separated from the first circular cover 3 for storage, reducing the overall space occupied, increasing the packaging density, and saving logistics costs.
[0025] When it is necessary to open the sterile container, remove the circular cap 3 from the container and place the circular cap 3 on its side on the table inside the laminar flow hood. The first side support 1 supports the cap, and the anti-slip pad 12 contacts the table surface to ensure that the circular cap 3 is placed stably. At this time, the wavy vent 32 allows air to pass through while effectively blocking external impurities from entering.
[0026] After the operation is completed, pick up the first circular cap 3 and place it on the sterile container. The sealing gasket 33 on the inner surface of the second circular cap 31 fits tightly with the container opening to form a good seal and prevent bacteria from entering the container.
