Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0029] Embodiment 1: Please refer to Figure 1-8 , a mooncake tray box made of PP material with an aluminum foil laminated packaging structure, including a box body 1. An octagonal protrusion 2 is provided at the middle position of the inner bottom end of the box body 1. An octagonal groove 3 is provided at the middle position of the bottom end of the box body 1. A mooncake tray 4 is horizontally placed at the inner bottom end of the box body 1. An octagonal rim 12 is provided at the top end of the box body 1. An aluminum foil laminated anti-oxidation component for sealing and anti-oxidation is provided inside the mooncake tray 4;

[0030] Please refer to Figure 1-8 , a mooncake tray box made of PP material with an aluminum foil laminated packaging structure further includes an aluminum foil laminated anti-oxidation component. The aluminum foil laminated anti-oxidation component includes a built-in circular groove 5. The built-in circular groove 5 is provided inside the middle position of the top end of the mooncake tray 4. A plurality of groups of horizontal partitions 6 are horizontally arranged inside the mooncake tray 4. A plurality of groups of vertical partitions 7 are longitudinally arranged between the front and rear ends inside the mooncake tray 4. A plurality of placement grids 8 are separated between the horizontal partitions 6 and the vertical partitions 7. A deoxidizer 9 is filled inside the placement grid 8. A PET layer 10 is covered on the top end of the built-in circular groove 5. An aluminum foil laminated sealing piece 11 is heat-sealed and bonded to the top end of the octagonal rim 12;

[0031] The external shape and size of the mooncake tray 4 are adapted to the internal shape and size of the box body 1. The mooncake tray 4 can move up and down along the inside of the box body 1. The box body 1, the mooncake tray 4, the built-in circular groove 5, and the octagonal edge 12 are made of PP material. The tops of the horizontal partition strips 6 and the vertical partition strips 7 are in contact with the bottom end of the PET partition layer 10. The top end of the PET partition layer 10 is flush with the top end of the mooncake tray 4. The external contour shapes of the aluminum foil laminated sealing piece 11 and the octagonal edge 12 are the same. The vertical center lines of the box body 1, the mooncake tray 4, and the built-in circular groove 5 coincide, improving the sealing ability and anti-oxidation ability;

[0032] Specifically, as Figure 1 , Figure 3 and Figure 5 shown, the aluminum foil laminated sealing piece 11 seals the top of the box body 1. There is a deoxidizer 9 in the many placement grids 8 separated by the horizontal partition strips 6 and the vertical partition strips 7 in the built-in circular groove 5. The deoxidizer 9 can absorb the oxygen in the box body 1 and delay the oxidation of the mooncakes. The PET partition layer 10 can isolate the deoxidizer 9 and the mooncakes.

[0033] Embodiment 2: Support feet 13 are respectively arranged at the eight corners at the bottom end of the mooncake tray 4. Reserved slots 14 are provided between every two of the support feet 13. An outer ring opening 15 is adhesively bonded to the outer circle at the top of the box body 1. Finger insertion grooves 16 are respectively arranged at the eight corners at the top end of the mooncake tray 4. An air vent 17 is arranged at the bottom end inside the finger insertion grooves 16. The finger insertion grooves 16 are arranged at equal intervals. The air vent 17 penetrates through the upper and lower ends of the mooncake tray 4, facilitating the taking and placing of the tray;

[0034] Specifically, as Figure 1 , Figure 2 and Figure 4 shown, the support feet 13 raise the mooncake tray 4, leaving a certain space at the bottom. The reserved slots 14 facilitate grasping the mooncake tray 4. When the mooncake tray 4 needs to be taken out, fingers can be inserted into the finger insertion grooves 16 to pinch the mooncake tray 4 and lift it. When the mooncake tray 4 is put down or lifted, air passes through the air vent 17, preventing the mooncake tray 4 from not being able to be put down or taken out due to air pressure problems.

[0035] Example 3: The top of the aluminum foil laminated sealing piece 11 is covered with a first polyester film printing layer 18. The top of the first polyester film printing layer 18 is adhesively bonded with a first nylon film wear-resistant layer 19. The rear end of the aluminum foil laminated sealing piece 11 is movably connected with a sealing tear strip 22. The top of the sealing tear strip 22 is covered with a second polyester film printing layer 21. The top of the second polyester film printing layer 21 is adhesively bonded with a second polyester film wear-resistant layer 20. The top of the rear end of the sealing tear strip 22 is evenly coated with an adhesive 25. A release paper 23 is applied to the rear end of the adhesive 25. A tear paper head 24 is provided at the bottom of the release paper 23. The aluminum foil laminated sealing piece 11 and the sealing tear strip 22 are made of the same material, and the sealing tear strip 22 and the tear paper head 24 are not connected, which is convenient for winding up the sealing piece;

[0036] Specifically, as Figure 1 , Figure 6 and Figure 7 shown, the torn aluminum foil laminated sealing piece 11 is rolled into a tube. Then, the release paper 23 on the back of the sealing tear strip 22 is torn off. The tear paper head 24 at the bottom of the release paper 23 facilitates its quick tearing. Then, the adhesive 25 on the back of the sealing tear strip 22 is pressed on the tubular aluminum foil laminated sealing piece 11, and the aluminum foil laminated sealing piece 11 becomes a tubular structure, which is not easy to flutter with the wind and is more convenient to tidy up.

[0037] Example 4: As Figure 1 Figure 8 shown, there is another form of the box body 1. The box body 1 is circular;

[0038] Working principle: When the utility model is in use, first, the mooncake tray 4 is placed inside the box body 1 to support the mooncakes. The aluminum foil laminated sealing piece 11 seals the top of the box body 1. There is a deoxidizer 9 in the many placement grids 8 separated by the horizontal partition strips 6 and the vertical partition strips 7 in the built-in circular groove 5. The deoxidizer 9 can absorb the oxygen in the box body 1 and delay the oxidation of the mooncakes. The PET partition layer 10 can isolate the deoxidizer 9 and the mooncakes. When placing the mooncake tray 4, the support feet 13 can raise the mooncake tray 4 to leave a certain space at the bottom. The reserved groove 14 facilitates grasping the mooncake tray 4. When it is necessary to take out the mooncake tray 4, the finger is inserted and the fingertip is buckled into the groove 16 to pinch the mooncake tray 4 and lift it up. When putting down or lifting the mooncake tray 4, air passes through the ventilation holes 17 to prevent the mooncake tray 4 from not being able to be put down or taken out due to air pressure problems. When it is necessary to open the aluminum foil laminated sealing piece 11, pinch the sealing tear strip 22 and tear it upwards. The torn aluminum foil laminated sealing piece 11 is rolled into a tube. Then, the release paper 23 on the back of the sealing tear strip 22 is torn off. The tear paper head 24 at the bottom of the release paper 23 facilitates its quick tearing. Then, the adhesive 25 on the back of the sealing tear strip 22 is pressed on the tubular aluminum foil laminated sealing piece 11, and the aluminum foil laminated sealing piece 11 becomes a tubular structure, which is not easy to flutter with the wind and is more convenient to tidy up.
