[0034] See also Figure 1 and Figure 2 One embodiment of the present invention provides a disposable anti-theft lunch box, including: a first box body 10, a second box body 20 and an anti-theft seal 30.

[0035] The first box body 10 and the second box body 20 are connected as a whole through an anti-theft seal 30; a plurality of first inverted portions 11 are provided on the rear side of the first box body 10, and the plurality of first inverted portions 11 are arranged in sequence along the rear side of the first box body 10; a plurality of first buckle holes 21 are provided on the rear side of the second box body 20, and the plurality of first buckle holes 21 are arranged in sequence along the rear side of the second box body 20.

[0036] A first tear-off portion 31 and a second tear-off portion 32 are formed on the anti-theft seal 30, and the anti-theft seal 30 is connected to the front side of the first box body 10, the left side of the first box body 10, and the right side of the first box body 10 through the first tear-off portion 31, and the first tear-off portion 31 extends along the left side of the first box body 10, the front side of the first box body 10, and the side of the first box body 10 in sequence, and the anti-theft seal 30 is connected to the front side of the second box body 20, the left side of the second box body 20, and the right side of the second box body 20 through the second tear-off portion 32, and the second tear-off portion 32 extends along the left side of the second box body 20, the front side of the second box body 20, and the side of the second box body 20 in sequence.

[0037] The specific structure of the first tearing portion 31 and the second tearing portion 32 can be designed according to actual needs. For example, the first tearing portion 31 and the second tearing portion 32 both include a plurality of connection points. The connection points of the first tearing portion 31 and the connection points of the second tearing portion 32 are arranged along the edge of the anti-theft seal 30. The connection points of the first tearing portion 31 are arranged along the front side of the first box body 10, the left side of the first box body 10, and the right side of the first box body 10 in sequence. The connection points of the second tearing portion 32 are arranged along the front side of the second box body 20, the left side of the second box body 20, and the right side of the second box body 20 in sequence. There is a certain distance between the adjacent connection points of the first tearing portion 31, and there is a certain distance between the adjacent connection points of the second tearing portion 32, so as to reduce the difficulty of the user tearing and damaging the first tearing portion 31 and the second tearing portion 32. Of course, the first tearing portion 31 and the second tearing portion 32 can also adopt tear marks that are easy to tear, and the thickness of the tear marks is smaller than the thickness of the anti-theft seal 30.

[0038] The anti-theft seal 30 is also provided with a plurality of second undercut portions 33 and a plurality of second buckle holes 34 . The plurality of second undercut portions 33 are evenly arranged on the left and right sides of the first box body 10 , and the plurality of second buckle holes 34 are evenly arranged on the left and right sides of the first box body 10 .

[0039] See also Figure 1 Before the disposable anti-theft lunch box is in the packaging state, the first inverted buckle portion 11 is not connected to the first buckle hole 21, and the second inverted buckle portion 11 is not connected to the second buckle hole 34, so the first box body 10 and the second box body 20 can be flatly unfolded, which is convenient for stacking and transportation. The stacking method can be that the first box body 10 extends into the first box body 10 of the adjacent disposable anti-theft lunch box, and the second box body 20 extends into the second box body 20 of the adjacent disposable anti-theft lunch box. And at this time, it is also convenient for users to place meals into the first box body 10 and / or the second box body 20.

[0040] See also Figure 2 After placing the food into the first box body 10 and / or the second box body 20, the disposable anti-theft lunch box needs to be switched to a packaging state. At this time, the first box body 10 and the second box body 20 are flipped toward each other so that the anti-theft seal 30 is located between the front side of the first box body 10 and the front side of the second box body 20. The anti-theft seal 30 is bent when the disposable anti-theft lunch box is in the packaging state so that the first box body 10 and the second box body 20 are close to or abut against each other. The first box body 10 and the second box body 20 are surrounded together to form a accommodating space. The food is located in the accommodating space. At this time, the first box body The rear side of the first box body 10 is close to the rear side of the second box body 20. By utilizing the bendability of the anti-theft seal 30, the first box body 10 and the second box body 20 are rotated and misaligned with each other, and the first inverted portion 11 can be tilted to align with the first buckle hole 21. Then the first box body 10 and the second box body 20 restore their positions, so that the first inverted portion 11 is correspondingly inserted into the first buckle hole 21 to make the first inverted portion 11 and the first buckle hole 21 inseparable. The rear side of the first box body 10 and the rear side of the second box body 20 cannot move away from each other, so it is impossible to steal food from the rear side of the accommodating space or take other bad actions.

[0041] As the anti-theft seal 30 is bent and folded, the part of the anti-theft seal 30 located on the left side of the first box body 10 is close to the part of the anti-theft seal 30 located on the left side of the second box body 20, and the part of the anti-theft seal 30 located on the right side of the first box body 10 is close to the part of the anti-theft seal 30 located on the right side of the second box body 20, so that the second inverted portion 33 can be correspondingly inserted into the second buckle hole 34 so that the second inverted portion 33 and the second buckle hole 34 are non-detachably connected. The cooperation of the second inverted portion and the second buckle hole 34 is restricted so that the left side of the first box body 10 and the left side of the second box body 20 cannot move away from each other, and the right side of the first box body 10 and the right side of the second box body 20 cannot move away from each other, so it is impossible to steal food from the left and right sides of the accommodating space or take other bad actions.

[0042] The front side of the first box body 10 and the front side of the second box body 20 cannot move away from each other due to the limitation of the anti-theft seal 30, so it is impossible to steal food or take other bad actions from the front side of the accommodating space.

[0043] In summary, when the disposable anti-theft lunch box is in a packaged state, the four sides of the storage space are blocked, making it impossible to steal food or take other bad actions, thereby improving the overall safety and sealing of the lunch box. Moreover, if only the front and back sides of the lunch box are fixed and locked, and there is no locking structure or anti-theft structure on the left and right sides, since the lunch box is usually made of elastic materials, it is easy to form a larger opening on the side of the lunch box after the lid of the lunch box is bent upward and the box body is bent downward, and food can be easily taken out from the side opening. The present invention can lock the lunch box without dead angles in the front, back, left and right, greatly improving safety.

[0044] See also Figure 3 When the disposable anti-theft lunch box is unpacked, the user can tear the anti-theft seal 30 along the left side, front side and right side of the whole lunch box in sequence, thereby destroying the first tear portion 31 and the second tear portion 32, so that the anti-theft seal 30 is separated from the first box body 10 and the second box body 20, and the first box body 10 and the second box body 20 can be opened at this time. At this time, the edges of the first box body 10 and the second box body 20 are relatively clean and tidy, and the first box body 10 and the second box body 20 are connected only by the cooperation of the second inverted portion 33 and the second buckle hole 34. The user usually eats from the front side of the lunch box, or at the left and right sides of the lunch box near the front side. Therefore, the structure of the first box body 10 and the second box body 20 located on the rear side will not affect eating, and other anti-theft structures are arranged on the anti-theft seal 30. After the anti-theft seal 30 is torn off, no residual structure will be left on the front side, left side or right side of the first box body 10 and the front side, left side or right side of the second box body 20, thereby not hindering the user's eating process.

[0045] The anti-theft seal 30 cannot be installed back on the first box body 10 and the second box body 20 due to the damage of the first tear portion 31 and the second tear portion 32. Therefore, the user can observe the first tear portion 31 and the second tear portion 32 to determine whether the lunch box has been opened.

[0046] In the prior art, a crease is usually used to achieve rotational fit between the box body and the box lid, which results in that when the box body and the box lid are opened, due to the elasticity of the crease, the elastic force of the crease will cause the box lid to rotate relative to the box body to an angle that is not suitable for the user, affecting the user's eating of food. In some optional embodiments, the first inverted portion 11 and the first buckle hole 21 are rotationally matched, so that the user can rotate the first box body 10 and the second box body 20 when the disposable anti-theft lunch box is unpacked. Due to the rotational fit of the first inverted portion 11 and the first buckle hole 21, the first box body 10 can be directly rotated to an unfolded state at 180° with the second box body 20, thereby avoiding affecting the user's eating of food.

[0047] The specific structure of the first inverted portion 11 can be designed according to actual needs. For example, in some optional embodiments, the first inverted portion 11 includes a base 12, a first connecting portion 13 and a first limiting end 14. The base 12 is connected to the first box body 10, and the first limiting end 14 is connected to the base 12 through the first connecting portion 13; a first limiting portion 22 is arranged in the first buckle hole 21. After the first limiting end 14 extends into the first buckle hole 21, the first limiting portion 22 abuts against the side of the first limiting end 14 facing the base 12 so that the first limiting end 14 cannot be separated from the first buckle hole 21, thereby realizing the non-detachable connection between the first inverted portion 11 and the first buckle hole 21.

[0048] In some optional embodiments, a first inclined hook portion 15 is formed on the side of the first limiting end 14 facing the base 12, and the first inclined hook portion 15 gradually extends in a radial direction of the first buckle hole 21 toward the base 12, and the first limiting portion 22 gradually extends in a radial direction of the first buckle hole 21 toward the base 12. The first inclined hook portion 15 is hooked with the first limiting portion 22. When the first limiting end 14 has a tendency to disengage from the first buckle hole 21, the first inclined hook portion 15 will squeeze the first limiting portion 22, so that the first limiting portion 22 is pressed toward the middle position of the first buckle hole 21, which makes it impossible for the first limiting end 14 to cross the first limiting portion 22 and disengage from the first buckle hole 21, thereby improving the stability of the first limiting end 14 being locked.

[0049] In some optional embodiments, the end of the first limiting terminal 14 is tapered, so as to facilitate the first limiting terminal 14 to be squeezed into the first buckle hole 21 and pass over the first limiting portion 22 .

[0050] In some optional embodiments, the first button hole 21 is formed with a first introduction port 23 , and the first introduction port 23 gradually expands in a direction away from the first button hole 21 , so as to facilitate guiding the first limiting end 14 into the first button hole 21 .

[0051] In this embodiment, a plurality of buckle seats 24 are disposed on the second box body 20 , and the first buckle holes 21 are correspondingly arranged in the buckle seats 24 .

[0052] See also Figure 4 The specific structure of the second inverted portion 33 can be designed according to actual needs. For example, in some optional embodiments, the second inverted portion 33 includes a second connecting portion 35 and a second limiting end 36. The root of the second limiting end 36 is connected to the anti-theft seal 30 through the second connecting portion 35. After the second limiting end 36 passes through the second buckle hole 34, the second connecting portion 35 is located in the second buckle hole 34, and the root of the second limiting end 36 abuts against the portion of the anti-theft seal 30 located around the second buckle hole 34, so that the second connecting portion 35 cannot be separated from the second buckle hole 34, thereby realizing the non-detachable connection between the second inverted portion 33 and the second buckle hole 34.

[0053] In some optional embodiments, a second inclined hook portion 37 is formed at the root of the second limiting end 36, and the second inclined hook portion 37 gradually extends in a direction away from the end of the second limiting end 36 in the radial direction of the second buckle hole 34, and a second limiting portion 38 is arranged around the second buckle hole 34, and the second limiting portion 38 gradually extends in a direction close to the end of the second limiting end 36 in the radial direction of the second buckle hole 34, and the second inclined hook portion 37 is hooked with the second limiting portion 38. When the second limiting end 36 has a tendency to retreat to the first buckle hole 21 so that the second connecting portion 35 is separated from the second buckle hole 34, the second inclined hook portion 37 will squeeze the second limiting portion 38, so that the second limiting portion 38 is pressed toward the central axis of the second buckle hole 34, so that the second limiting end 36 cannot pass through the second limiting portion 38 and pass through the second buckle hole 34, thereby improving the stability of the second limiting end 36 being locked.

[0054] In some optional embodiments, the end of the second limiting end 36 is tapered, so as to facilitate the second limiting end 36 to be squeezed into the second buckle hole 34 and pass through the second buckle hole 34.

[0055] In some optional embodiments, the second buckle hole 34 is formed with a second introduction port 39 , and the second introduction port 39 gradually expands in a direction away from the second buckle hole 34 , so as to facilitate guiding the second limiting end 36 to pass through the second buckle hole 34 .

[0056] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
