Detailed Description

The preferred embodiments of the present invention will be described in conjunction with the accompanying drawings, and it will be understood that they are described herein for the purpose of illustration and explanation and not limitation.

Referring to fig. 1, the disposable lunch box with a lock of the present invention comprises a box body 1 and a cover body 2 fastened with the box body 1. The top lateral wall of box body 1 is equipped with outside S-shaped turn-ups sealing strip 3, S-shaped turn-ups sealing strip 3 divide into and holds portion 31 and clamping part 32 tightly, 2 inner walls of lid are equipped with sealed sand grip 4, and when covering lid 2, the clamping part 32 of S-shaped turn-ups sealing strip 3 is gone into to sealed sand grip 4 card, just so can make box body 1 and lid 2 tightly sealed, prevents that the hot water juice from revealing.

Referring to fig. 2, the S-shaped flanged sealing strip 3 of the disposable lunch box with a lock catch of the present invention is provided with a lock tongue 5, and the top of the lid body 2 is provided with a lock groove 6. In this embodiment, the spring bolt 5 is 2, is relative setting on box body 1, the locked groove 6 also is 2, is relative setting on lid 2. The lock tongue 5 is T-shaped and is divided into a connecting part 51 and a locking part 52, and two ends of the connecting part 51 are respectively connected with the S-shaped flanging sealing strip 3 and the locking part 52. The locking part 52 may be square or oval, and the length of the locking part 52 is greater than that of the locking groove 6. When the cover body 2 is covered, the locking part 52 of the bolt 5 extends into the locking groove 6 to be mutually buckled, locked and fixed with the locking groove 6. In order to prevent the cover 2 from being opened after the locking and fixing, the length of the connecting portion 51 may be designed to be slightly longer than the length when the cover 2 is attached. To open the case 1, the lock portion 52 needs to be pulled out of the lock groove 6, and since the lock groove 6 is shorter than the lock portion 52, the lock portion 52 is broken when the lock groove 6 is pulled out, and it is possible to determine whether or not the lid 2 has been opened by whether or not the lock portion 52 is broken.

After pulling open spring bolt 5, spring bolt 5 can also act as the effect of pull ring, and before opening lid 2, upwards stimulate spring bolt 5, make the perk of S-shaped turn-ups sealing strip 3, will produce the clearance like this between S-shaped turn-ups sealing strip 3 and sealed sand grip 4, conveniently open lid 2.

Referring to fig. 3, the bottom of the box body 1 is provided with a plurality of circles of semicircular protrusions 7 which are circumferentially arranged, the semicircular protrusions 7 can increase friction force, so that the antiskid effect is achieved, and in the process of delivering takeaway, the slippage of the takeaway caused by shaking in the process of distribution is reduced. When the consumer takes the lunch box, the hand is placed on the semicircular bulge 7, and a certain heat insulation effect can be achieved.

The top of the cover body 2 is provided with a storage groove 8. The storage groove 8 can be used for placing tableware such as chopsticks and spoons, and can also be placed on the storage groove 8 and then discarded after eating.

In addition, the case body 1 or the cover body 2 is made of a paper material. Preferably, the case 1 or the cover 2 is made of a PE material.

The working principle of the interlocking lunch box of the invention is explained as follows:

before box body 1 and 2 locks of lid, hold the meal in box body 1 earlier, close lid 2 on box body 1 correspondingly again, wherein, the laminating of sealed sand grip 4 and the S-shaped turn-ups sealing strip 3 of lid 2 reaches totally enclosed effect, then inserts the locked portion 52 of spring bolt 5 in the locked groove 6, forms the hasp effect to the lid of accomplishing whole cutlery box closes the operation.

Compared with the prior art, the disposable lunch box with the lock catch has a complete lunch box structure formed by mutually buckling the box body 1 and the cover body 2 with the same structure, and particularly, the box body 1 and the cover body 2 are locked and fixed by inserting the lock tongue 5 into the lock groove 6, so that the box body 1 and the cover body 2 are reliably combined and are not easy to separate from each other, and the box body 1 and the cover body 2 are convenient to disassemble and assemble. In addition, the bolt 5 is inserted into the lock slot 6 to lock the upper and lower lunch boxes, if the lunch box is to be opened, the bolt 5 is damaged, and whether the bolt 5 is intact or not is observed, so that whether the lunch box is opened or not can be judged, and the lunch box is prevented from being polluted; the sealing convex strip 4 of the cover body 2 is attached to the S-shaped flanging sealing strip 3, so that soup in the meal box can be prevented from flowing out.

The above-mentioned embodiments only express several embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention.
