[0024] In this embodiment, a lower support plate 5 is fixedly connected to the outer surface of the lower silicone sheet 1 near the storage port 4, a protrusion 6 is fixedly connected to the upper surface of the lower support plate 5, an upper support plate 7 is fixedly connected to the outer surface of the upper silicone sheet 2 near the storage port 4, a groove 8 is provided on the lower surface of the upper support plate 7, and an arc-shaped nozzle plate 9 is provided on the outer surface of the lower support plate 5.
[0025] In practical use, the lower silicone sheet 1 is bonded to the upper silicone sheet 2 through the sealing ring 3, which supports and fixes the shape of the food storage box. The storage is completed through the storage opening 4. The lower support plate 5 and the upper support plate 7 can support and fix the shape of the storage opening 4, preventing deformation. The protrusion 6 can be inserted into the groove 8 to complete the seal. With the help of the arc nozzle plate 9, the integrity of the seal can be tested. The arc nozzle plate 9 also makes it easy to open the food storage bag, helping to check the seal and improve safety.
[0026] In this embodiment, the upper surface of the protrusion 6 is provided with a slot 10, the lower surface of the slot 10 is provided with a groove 11, the size of the groove 11 is larger than the size of the slot 10, the lower surface of the groove 8 is fixedly connected with a block 12, the lower surface of the block 12 is fixedly connected with a buckle 13, the size of the buckle 13 is larger than the size of the block 12.
[0027] In actual use, the card block 12, along with the buckle 13, is inserted into the card slot 11 under the card opening 10 to complete a tight closure. It works in conjunction with the protrusion 6 to be inserted into the groove 8 to complete a multi-layer seal, thereby improving sealing performance and safety.
[0028] In this embodiment, a lower friction strip 14 is provided on the upper surface of the arc nozzle plate 9, and an upper friction strip 15 is fixedly connected to the upper support plate 7 near the lower surface of the arc nozzle plate 9.
[0029] In practical use, the lower friction strip 14 and the upper friction strip 15 increase the friction of the outer surface of the arc nozzle plate 9, making it easier for the operator to open the sealing structure on the food storage bag by applying force up and down through the arc nozzle plate 9.

[0036] Working principle: During use, the lower silicone sheet 1 is bonded to the upper silicone sheet 2 via the sealing ring 3, simultaneously supporting and fixing the shape of the food storage container. Storage is achieved through the storage opening 4. The lower support plate 5 and upper support plate 7 support and fix the shape of the storage opening 4, preventing deformation, and simultaneously allowing the protrusion 6 to be engaged in the groove 8 to complete the seal. The arc-mouth plate 9 helps test the integrity of the seal, and it also facilitates opening the food storage bag to check the seal and improve safety. The locking block 12, with its buckle 13, engages with the slot 11 under the locking opening 10 to complete a tight seal. Combined with the protrusion 6 engaging in the groove 8, this completes a multi-layered seal. To improve sealing and safety, the lower friction strip 14 and upper friction strip 15 increase the friction of the outer surface of the arc nozzle plate 9, making it easier for the operator to open the sealing structure on the food storage bag by applying force up and down through the arc nozzle plate 9. The reinforcing ring 16 can strengthen the support and stability of the inner top and bottom walls of the lower silicone sheet 1 and the upper silicone sheet 2, ensuring that the food storage bag does not deform and can ensure the stability of the food storage bag. The storage date of the stored items can be written on the reminder sticker and placed into the reminder block 17 through the side opening 18, which can help the operator ensure that the items inside the food storage bag are consumed in time. The handle 19 makes it easy to pick up the food storage bag and facilitates operation.
