Description

Technical Field

[0001] The utility model relates to the field of lunch boxes, in particular to an injection-molded lunch box with an anti-theft lock. Background Art

[0002] Disposable fast food boxes have shifted from foam boxes to environmentally friendly boxes. The original foam boxes were eliminated because they were not resistant to high temperatures and the production process caused damage to the environment. They were replaced by plastic boxes, paper boxes, wooden boxes, degradable boxes, etc. Among them, plastic has the characteristics of low toxicity, high melting point, strong plasticity, simple production and relatively low cost, so it has become the mainstream material for making disposable fast food boxes. PP polypropylene has mechanical and thermal properties and is suitable for meal packaging. Lunch boxes are divided into environmentally friendly lunch boxes, mainly plastic, paper, starch and rare metal types.

[0003] Disposable plastic fast food boxes are mostly used in collective dining environments, but the existing disposable plastic fast food boxes are too simple in structure and lack anti-theft functions. Due to the complex collective dining environment (some people secretly try a bite), users cannot tell which ones have been opened and eaten, which can easily cause cross-infection of germs.

[0004] Therefore, it is necessary to provide a new injection molded lunch box with an anti-theft lock to solve the above-mentioned technical problems. Utility Model Content

[0005] In order to solve the above technical problems, the utility model provides an injection-molded lunch box with an anti-theft lock, which solves the problem that the existing collective dining environment is complex, while the structure of the plastic fast food box is too simple and lacks anti-theft function.

[0006] The utility model provides an injection-molded lunch box with an anti-theft lock, comprising a box body, a box cover is buckled on the top of the box body, a partition is fixed inside the box body, fixing blocks are fixed on both sides of the box body, a groove is opened on the surface of the fixing block, and a check block is fixed on the groove wall of the groove;

[0007] Connecting plates are movably arranged on both sides of the box cover, a push rod is fixed on one side of the connecting plate, the push rod extends into the interior of the groove, and two anti-theft sheets are symmetrically fixed on the push rod.

[0008] In a preferred embodiment, the anti-theft sheet has a thickness of 1-2 mm.

[0009] In a preferred embodiment, a lever is fixed on the connecting plate.

[0010] In a preferred embodiment, the box cover is provided with ventilation holes.

[0011] In a preferred embodiment, a plurality of slots are formed on the surface of the box body and the partition, an adjustment plate is arranged inside the box body, a fixing plate is fixed on the top of the adjustment plate, a card block is fixed on the bottom of the fixing plate, and the card block is embedded in the slots.

[0012] In a preferred embodiment, the adjustment plate and the box body are made of the same material.

[0013] Beneficial effects of the utility model:

[0014] 1. When the lunch box is used, after adding rice, the lid can be buckled on the top of the box body, and then the connecting plates on both sides of the lid can be moved toward the box body until the top rod and the anti-theft sheet are all inserted into the groove. When the user needs to eat, he only needs to forcefully push the two levers to drive the top rod and the anti-theft sheet to move. Since the two anti-theft sheets are in an eight-shaped structure, the top rod can only slide out of the groove after they are broken, and the user can open the lunch box. When the user finds that the anti-theft sheet is broken before eating, it can be judged that the food has been stolen;

[0015] 2. By moving the position of the adjustment plate, different types of storage space inside the box can be changed, which increases the flexibility of the box when in use. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The utility model is further described below in conjunction with the accompanying drawings and implementation modes.

[0022] Please refer to Figure 1 , Figure 2 , Figure 3 as well as Figure 4 ,in Figure 1A three-dimensional view of the overall structure of the injection-molded lunch box with an anti-theft lock provided by the utility model; Figure 2 A schematic diagram of the three-dimensional structure of the box body provided by the utility model; Figure 3 A side view of the box body provided by the utility model; Figure 4 This is a structural schematic diagram of the fixing block provided by the utility model.

[0023] In the specific implementation process, Figure 1-Figure 4 As shown, it includes a box body 1, a box cover 2 is buckled on the top of the box body 1, and the box cover 2 is provided with air holes 11 to facilitate the discharge of hot air inside the box body 1, a partition 3 is fixed inside the box body 1, and fixed blocks 4 are fixed on both sides of the box body 1. A groove 5 is opened on the surface of the fixed block 4, and a check block 6 is fixed on the groove wall of the groove 5. Connecting plates 7 are movably provided on both sides of the box cover 2, and a push rod 8 is fixed on one side of the connecting plate 7. The push rod 8 extends into the inside of the groove 5, and two anti-theft sheets 9 are symmetrically fixed on the push rod 8. The thickness of the anti-theft sheet 9 is 1-2mm. The anti-theft sheet 9 of this thickness is easy to break, which is convenient for users to open the lunch box, and a handle 10 is fixed on the connecting plate 7 to further facilitate users to move the position of the connecting plate 7.

[0024] A plurality of card slots 12 are provided on the surface of the box body 1 and the partition 3, and an adjusting plate 13 is provided inside the box body 1. A fixing plate 14 is fixed on the top of the adjusting plate 13, and a card block 15 is fixed on the bottom of the fixing plate 14. The card block 15 is engaged with the card slot 12. The adjusting plate 13 is placed between the two card slots 12, and the card block 15 is then inserted into the card slot 12 to complete the fixing of the adjusting plate 13. The operation is simple and convenient. By moving the position of the adjusting plate 13, different types of storage space inside the box body 1 can be changed, thereby increasing the flexibility of the box body 1 when in use.

[0025] The adjustment plate 13 and the box body 1 are made of the same material, specifically PP polypropylene, which is non-toxic, tasteless and odorless. PP polypropylene is relatively soft. The general operating temperature of PP polypropylene is -6 degrees to +120 degrees, so it is particularly suitable for holding hot rice and hot dishes. It can be heated in a microwave oven or even steamed in a steam cabinet. The operating temperature of the modified PP polypropylene can be controlled at -18 degrees to +110 degrees. In addition to being heated to 100 degrees for use, the lunch box made of this PP polypropylene can also be refrigerated for use.

[0026] Working principle of the utility model: when the lunch box is used, after adding rice, the box cover 2 can be buckled on the box body 1, and then the connecting plates 7 on both sides of the box cover 2 can be moved toward the box body 1 until the top rod 8 and the anti-theft sheet 9 are all inserted into the groove 5. When the user needs to eat, he only needs to forcefully push the two levers 10 to drive the top rod 8 and the anti-theft sheet 9 to move. Since the two anti-theft sheets 9 are in an "eight" structure, the top rod 8 can slide out of the groove 5 only after they are broken, and the user can open the lunch box. When the user finds that the anti-theft sheet 9 is broken before eating, it can be judged that the food has been stolen.

[0027] By moving the position of the adjustment plate 13 , different types of storage spaces inside the box body 1 can be changed, thereby increasing the flexibility of the box body 1 when in use.

[0028] The circuits and controls involved in the present invention are all prior art and will not be described in detail here.
