[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Example: Refer to Figure 1-4An anti-theft insulated lunch box includes a lunch box body 1, a lunch box lid 2 rotatably mounted on the lunch box body 1, an adhesive connecting plate 4 rotatably mounted on one side of the lunch box body 1, an upper cardboard 8 connected to one side of the lunch box lid 2, and a strong adhesive component provided on the upper cardboard 8. The strong adhesive component is adapted to the adhesive connecting plate 4. The interior of the lunch box body 1 is provided with a storage slot, and the inner wall of the storage slot is provided with lunch box insulation foil 3. After the food is filled, the lunch box lid 2 is closed to protect the food. The lunch box insulation foil 3 is provided inside the lunch box body 1. The metal material of the foil can effectively reflect heat radiation and reduce the loss of internal heat, thereby playing a role in heat preservation and avoiding the problem of rapid cooling of the delivered food.

[0017] Furthermore, the top of the adhesive connecting plate 4 is provided with a placement groove 5, and the upper cardboard 8 is located in the placement groove 5. The strong adhesive component includes an adhesive strip 10 fixedly installed on the side of the upper cardboard 8. A fixed adhesive plate 11 is provided on one side of the adhesive strip 10. The top of the adhesive connecting plate 4 is provided with an adhesive surface 6, which is adapted to the fixed adhesive plate 11. An oil film paper 12 is provided on one side of the fixed adhesive plate 11, and a tear head 13 is provided on one side of the oil film paper 12. After packaging, the upper cardboard 8 is placed in the placement groove 5 on the adhesive connecting plate 4, and then the tear head 13 is pinched to tear off the oil film paper 12. Then the fixed adhesive plate 11 is attached to the adhesive surface 6 on the adhesive connecting plate 4 to achieve the connection and fixation between the upper cardboard 8 and the adhesive connecting plate 4. The fixed adhesive plate 11 is a strong adhesive tape, such as 3M tape, which can achieve the purpose of not being easy to tear after adhesion.

[0018] Furthermore, the width of the fixing adhesive plate 11 is greater than the width of the adhesive surface 6. Therefore, there is still a large adhesive area on one side of the fixing adhesive plate 11. At this time, when the adhesive connecting plate 4 and the upper cardboard 8 are pressed down, the adhesive connecting plate 4 will rotate around the rotating seat 7. The unattached part of the fixing adhesive plate 11 will be attached to one side of the lunch box body 1 without taking up space. The result is more aesthetically pleasing after attachment. The strong fixing adhesive plate 11 achieves a sealing connection, preventing the lunch box lid 2 from being opened during food delivery and causing the food to be stolen.

[0019] Furthermore, a tear line hole 9 is provided at the top of the upper cardboard 8, and a tearing block 14 is fixedly installed on one side of the upper cardboard 8. The tearing block 14 is located on one side of the tear line hole 9. A rotating seat 7 is provided between the lunch box body 1 and the adhesive connecting plate 4. The rotating seat 7 is connected by rubber or plastic. The tear line hole 9 makes it easy for the upper cardboard 8 to be torn open. After the diner receives the lunch box, he / she pinches the adhesive connecting plate 4 and the adhesive strip 10, and then pulls the tearing block 14 with his / her other hand to tear the upper cardboard 8 along the tear line hole 9, thereby making it easy to open the lunch box lid 2 and eat.

[0020] In use: A lid 2 is provided on the main body 1 of the lunch box. After filling the lunch box, the lid 2 is closed to protect the food. The insulating foil 3 is provided to keep the food warm and prevent it from cooling down quickly during delivery. After packaging, the upper cardboard 8 is placed in the placement slot 5, and then the oil film 12 is peeled off. The fixing adhesive plate 11 is attached to the adhesive surface 6 to connect and fix the upper cardboard 8 to the adhesive connecting plate 4. The width of the fixing adhesive plate 11 is greater than the width of the adhesive surface 6. At this time, the adhesive connecting plate 4 and the upper cardboard 8 are pressed down. The adhesive connecting plate 4 will rotate around the rotating seat 7. The unattached part of the fixing adhesive plate 11 will stick to one side of the main body 1 of the lunch box without taking up space. The glued part is more aesthetically pleasing. The strong fixing adhesive plate 11 achieves a sealing connection to prevent the food from being stolen when the lid 2 is opened during delivery. The tear hole 9 is provided to make it easy to tear open the upper cardboard 8.

[0021] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
