Technical Field
[0001] This utility model relates to the field of food storage device technology, specifically to a multi-layer sealed storage tank for preventing component migration. Background Technology
[0002] Composite flexible packaging is a new type of flexible packaging material formed by combining two or more different materials through processes such as coating, hot pressing, and bonding, which can fully utilize the advantages of each component material. It is mainly used in the food, pharmaceutical, cosmetic, and daily chemical industries, and features lightweight, strong protection, and excellent machinability. Its material structure includes various forms such as plastic composite film, aluminized composite film, and paper-aluminum-plastic composite film, achieving functions such as oxygen barrier, moisture protection, light blocking, and heat sealing.
[0003] When storing food, composite flexible packaging materials are used for packaging. However, when packaging food with composite flexible packaging materials, adhesives are used to seal the joints of the composite flexible packaging materials (such as the film of the composite flexible packaging material) to form a bag. This can cause indirect contact between the food and the adhesive, which may cause the adhesive to adhere to the surface of the food. Therefore, it is necessary to use multi-layer sealed storage tanks that prevent component migration to directly separate the packaging materials from the food and prevent the adhesive from mixing with the food.
[0004] This invention proposes a multi-layer sealed storage tank for preventing component migration, in order to solve the above-mentioned problems. Utility Model Content

(The limiting component 8 is a prefabricated part, that is, the sealing cover 801 and the screw 802 are connected as one piece to form a bolt-like structure. First, the screw 802 is screwed into the screw hole 603, and then the limiting block 803 is fixed to the bottom end of the screw 802, so that the sealing cover 801 and the limiting block 803 are located on the upper and lower sides of the partition 601 respectively.) The screw 802 is threadedly connected to the side wall of the screw hole 603. The sealing cover 801 is connected to the top end of the screw 802, and the limiting block 803 is connected to the bottom end of the screw 802. The sealing slot 602, the placement slot 604, the limiting block 803, and the sealing cover 801 are all cylindrical in shape. The sealing cover 801 is connected to the side wall of the sealing gasket. The limiting block 803 can be inserted into the placement slot 604, and the sealing cover 801 can be inserted into the sealing slot 602. Storage component 7 includes storage box 701, sealing door 702, guide plate 703, and limiting groove 704. The top opening of storage box 701 is rotatably connected to sealing door 702.

[0022] The working principle and usage process of this utility model are as follows: In specific use, the card plate 5 engages with the card slot 2, allowing the cover plate 3 and top plate 4 to be combined with the tank body 1 to form a complete storage tank. Before engaging the card plate 5 with the card slot 2, open the sealing door 702, place the food into the storage box 701, then close the storage box 701, and slide the guide plate 703 into the guide groove 605, so that the storage box 701 can be guided into the area formed by the partition 601 and the tank body 1. The rubber sleeve 10 provides cushioning for the movement of the storage box 701. Then, align the limiting groove 704 with the placement groove 604, and rotate the sealing cover 801 to make the seal... The cap 801 drives the screw 802 to rotate, causing the cap 801 to move from top to bottom (the initial state of the cap 801 is above the sealing slot 602, while the initial state of the limiting block 803 is inside the placement slot 604). The screw 802 drives the limiting block 803 to move from the placement slot 604 into the limiting slot 704, thereby restricting the movement of the sealing door 702 and thus restricting the movement of the storage box 701. Then, the card plate 5 is engaged with the card slot 2 to completely close the storage tank. Then, a packaging material film 9 is placed around the storage tank to completely prevent the adhesive from contacting the food, and the packaging material film 9 can also isolate the storage tank from the outside air.
