AI Technical Summary
The sealing strips of existing airtight lunch boxes are prone to aging, which reduces the sealing effect and affects the use of the lunch boxes and food storage.
The design uses a structure of interlocking convex rings and grooves to replace traditional sealing strips. The interlocking of the convex rings and grooves achieves a sealed connection between the lid and the box body, enhancing the sealing effect and avoiding the aging problem of sealing strips.
It achieves a long-term stable sealing effect for sealed lunch boxes, eliminating the need for sealing strips and avoiding the problem of reduced sealing effect caused by the aging of sealing strips.

Abstract
Description
TECHNICAL FIELD
[0001] The utility model relates to sealed lunch box manufacturing technical field, especially a new sealed lunch box. BACKGROUND
[0002] The existing sealed lunch box generally adopts the sealing strip to seal and connect the box body and the box cover, the sealing strip is sleeved on the connecting edge of the box cover, the inner side of the edge of the box body is tightly combined with the sealing strip of the box cover to realize the sealing connection when the box cover is connected with the box body, however, the sealing strip is generally made of plastic, the sealing strip is aged after the long-term use of the sealed lunch box, the aging problem of the sealing strip is prone to occur under the influence of the use environment, the sealing effect of the sealing strip is greatly reduced, and the use of the lunch box and food storage are affected. SUMMARY
[0003] In view of the above-mentioned deficiencies of the prior art, the utility model aims at providing a new sealed lunch box which has simple structure and long-term stable sealing effect.
[0004] The utility model realizes the above-mentioned purpose in this way:
[0005] The utility model discloses a new sealed lunch box, including box body and box cover, the box body includes the body, and the convex ring is connected to the edge of the body, the box cover includes the cover surface body, and the recess is connected to the edge of the cover surface body, the convex ring and the recess are mutually nested.
[0006] Further, the outer edge of the convex ring is transversely bent to form an outer supporting edge, the outer edge of the recess is pressed against the outer supporting edge, the inner edge of the convex ring is transversely bent and integrated with the edge of the body to form a step-shaped structure one, the inner edge of the recess is transversely bent and integrated with the edge of the cover surface body to form a step-shaped structure two, and the step-shaped structure two and the step-shaped structure one are mutually spliced and sealed.
[0007] Further, the cover surface body further protrudes upward to form a decorative part, and the outer edge of the recess is further connected with a pull-tab, and the pull-tab protrudes outward horizontally relative to the box body.
[0008] The utility model has the advantages of:
[0009] The utility model discloses a new sealed lunch box, which is sealed and connected with the box body by the mutual nesting of the convex ring and the recess, without the sealing strip, so that the aging problem of the sealing strip is not worried about, and the sealing effect of the lunch box can be long-term and stable. BRIEF DESCRIPTION OF DRAWINGS
[0010] The utility model is further illustrated in connection with the drawings and embodiments:
[0011] Figure 1 It is the whole structure schematic view of a novel sealing lunch box in one embodiment of the utility model;
[0012] Figure 2 It is the box body structure schematic view of a novel sealing lunch box in one embodiment of the utility model;
[0013] Figure 3 It is the box cover structure schematic view of a novel sealing lunch box in one embodiment of the utility model.
[0014] In the drawing, 1 box body, 2 box cover, 11 body, 12 convex ring, 21 cover body, 22 recess, 121 outer supporting edge, 13 step structure one, 23 step structure two, 211 decoration part, 221 easy-to-pull piece. Specific implementation
[0015] In order to make the purpose, technical scheme and advantages of the utility model more clear and obvious, the utility model is further explained in detail below by combining with the embodiment and the drawing, and the illustrative embodiment and the explanation thereof of the utility model are only used for analyzing the utility model, and do not serve as the limitation of the utility model.
[0016] Figures 1-3 The specific structure of a novel sealing lunch box in one embodiment of the utility model is shown, which comprises a box body 1 and a box cover 2, the box body 1 comprises a body 11 and a convex ring 12 connected around the edge of the body 11, the box cover 2 comprises a cover body 21 and a recess 22 connected around the edge of the cover body 21, the convex ring 12 and the recess 22 are mutually fitted, by utilizing the mutual fitting of the convex ring 12 and the recess 22, the box cover 2 and the box body 1 can be sealed and connected, the sealing strip is not needed to be used to seal and connect the box cover 2 and the box body 1, thus the aging problem of the sealing strip does not need to be worried, and the sealing effect of the lunch box can be stably maintained for a long time.
[0017] Further, in the embodiment, as shown in Figure 2 And Figure 3 The outer edge of the convex ring 12 is transversely bent to form an outer supporting edge 121, and the outer edge of the recess 22 is pressed against the outer supporting edge 121; the inner edge of the convex ring 12 is transversely bent and integrated with the edge of the body 11 to form a step structure one 13, and the inner edge of the recess 22 is transversely bent and integrated with the edge of the cover body 21 to form a step structure two 23, the step structure two 23 and the step structure one 13 are mutually spliced and sealed; the step structure two 23 and the step structure one 13 are mutually spliced and sealed, which not only can increase the sealing area, thereby enhancing the sealing effect, but also can firmly connect the box body 1 and the box cover 2.
[0018] Further, in the present embodiment, as shown in Figure 1 and Figure 3 The cover surface 21 is further provided with a decorative portion 211 protruding upwardly, and the outer edge of the groove 22 is further connected with a pull-tab 221 protruding outwardly horizontally relative to the box body 11.
[0019] It can be understood that the above embodiments only express the preferred embodiments of the present application, and the description is more specific and detailed, but it cannot be understood as the limitation of the scope of the present application patent; it should be pointed out that for ordinary skilled in the art, the above technical features can be freely combined without departing from the concept of the present application, and several modifications and improvements can be made, which all belong to the protection scope of the present application; therefore, any equivalent transformation and modification made to the present application claims and scope shall belong to the scope of the present application claims.
