[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] See also Figure 1-5 The utility model provides an embodiment: a PET bubble box, comprising a PET box body 1 and a cover body 2 arranged at the top opening position of the PET box body 1, a lower supporting edge 3 is installed at the bottom edge of the cover body 2, and a locking hook 7 is fixed at the corner position of the bottom end of the lower supporting edge 3, an upper supporting edge 5 that can contact the lower supporting edge 3 is arranged at the outer edge of the top opening of the PET box body 1, and an outer convex plate 4 is fixed on the outer walls of both sides of the upper supporting edge 5, and T-shaped grooves 8 are opened on both sides of the top of the outer convex plate 4, a U-shaped seat 9 is fixed inside the T-shaped groove 8, and an elastic locking structure 10 for buckling with the locking hook 7 is arranged inside the U-shaped seat 9, and the U-shaped seat 9 and the elastic locking structure 10 are hidden in the outer convex plate 4, which has little effect on the appearance structure of the box body, and the outer convex plate 4 can still provide space for users to hold their hands;

[0020] The PET box body 1 is injection molded, with a smooth surface and no burrs. The outer wall edge of the PET box body 1 is designed to be chamfered or rounded to prevent scratching hands or damaging packaging;

[0021] A cutout groove 6 extending upward is provided at the bottom end of the lower supporting edge 3 on one side of the lock hook 7, and the lock hook 7 can be sunk into the T-shaped groove 8, and part of the elastic lock structure 10 is located in the cutout groove 6, and the cover body 2 and the PET box body 1 are locked and connected through the lock hook 7 and the elastic lock structure 10;

[0022] The elastic lock structure 10 includes a support shaft 1001 rotatably mounted inside the U-shaped seat 9, and a lock block 1002 fixed on the surface of the support shaft 1001. A hook portion 1003 is provided at the top of the lock block 1002. The hook portion 1003 and the lock hook 7 are buckled with each other. A torsion spring 1004 is installed on the surface of the support shaft 1001. During the buckling process of the cover body 2 and the PET box body 1, the user manually presses one end of the hook portion 1003 to make the hook portion 1003 tilt upward. At this time, the lock block 1002 is turned around with the support shaft 1001 as the center, and the torsion spring 1004 is in a compressed state. When the lock hook 7 enters the T-shaped groove 8, the user no longer applies force to the lock block 1002, and the torsion spring 1004 forces the lock block 1002 and the hook portion 1003 to reset, so that the hook portion 1003 and the U-shaped seat 9 are buckled.

[0023] The torsion spring 1004 allows the lock block 1002 to maintain a tight connection with the lock hook 7 even when the box body is subjected to external force or vibration, thereby preventing the box body from accidentally opening during transportation or use. The user only needs to press lightly to open and close the box body, without the need for additional tools or complicated operations, thus improving the convenience of use.

[0024] The locking block 1002 is made of a hard plastic material. The hard plastic material has high strength and hardness, and can provide good structural support, compression resistance and wear resistance. When the locking block 1002 is used as a connecting piece, the improved wear resistance enables the locking block 1002 to maintain a good connection state for a long time, thereby extending the service life of the product.

[0025] An upper eave 201 is integrally formed at the edge of the top of the cover 2, and a lip plate 202 is fixed to the outer surface of the cover 2. The arrangement of the upper eave 201 and the lip plate 202 can increase the stability of the overall structure of the cover 2. These edge designs can provide more support and reinforcement for the cover 2, making the cover 2 more solid and stable, less prone to deformation and loosening, and extending the service life of the product;

[0026] A convex eave 101 is integrally formed at the top edge of the PET box body 1. After the cover body 2 and the PET box body 1 are buckled together, the outer wall of the convex eave 101 and the inner wall of the lower supporting edge 3 contact each other to form a sealing surface. When the cover body 2 and the PET box body 1 are buckled together, the inner wall of the lower supporting edge 3 and the outer wall of the convex eave 101 contact each other to form a sealing surface. Through the close contact between the inner wall and the outer wall, the entry of air, moisture or foreign matter can be effectively prevented, and the items in the box are protected from external influences, and the sealing performance between the PET box body 1 and the cover body 2 is effectively enhanced;

[0027] An outer convex edge 301 is integrally formed at the chamfered position on the outer wall on one side of the lower supporting edge 3. The design of the outer convex edge 301 makes it more convenient and quick for the user to open the cover body 2. The user can easily grasp the box body through the outer convex edge 301 and then open the cover body 2 without the need for additional tools or complicated operations, thereby improving the convenience of using the box body.

[0028] When the embodiment of the present application is used, the user first takes out the items to be stored in the PET box body 1, places the items in the PET box body 1, and then takes out the cover body 2, so that the cover body 2 is buckled at the opening position at the top of the PET box body 1. During the buckling process of the cover body 2, the user pre-bends the elastic locking structure 10, so that the elastic locking structure 10 is actuated and in an unlocked state, until the lower surface of the lower supporting edge 3 and the upper surface of the upper supporting edge 5 contact each other, at which time the locking hook 7 sinks into the T-shaped groove 8, and part of the elastic locking structure 10 is located in the cut-out groove 6. Then the user releases the elastic locking structure 10, so that The elastic locking structure 10 and the locking hook 7 can be buckled with each other. At this time, the cover body 2 and the PET box body 1 are locked and connected through the locking hook 7 and the elastic locking structure 10. The lower supporting edge 3 and the upper supporting edge 5 in the box body can provide a larger contact area and support area, so that the connection between the cover body and the box body is more firm and stable. At the same time, combined with the locking hook 7 and the elastic locking structure 10, it can ensure that the box body and the cover body can be completely locked and connected, and it is not easy to detach or separate. In this way, whether in daily use or during transportation, it can better protect the internal items and improve the safety and reliability of the product.
