Description

Structure of lunch box cover

Technical Field

The utility model relates to the technical field of lunch boxes, in particular to a lunch box cover structure.

Background

The portable tableware has wide use in work and life, and can be used for bringing convenience to users to carry food during work or outdoor play.

In the prior art, when the types of the boxes are different and the functions are complete, the use requirements of different users can be met to different degrees. With the progress of technology, it is difficult to break through space functionally, so that it is necessary for some manufacturers of lunch boxes to start from the user experience, and the market competitiveness of the product is improved.

When the most basic structure of the box comprises a box body and a cover body, the box body is in pin joint fit with the cover body under normal conditions, and the limit is realized through devices such as a buckle, and the cover body can be turned over to take and put food when the buckle is opened. Such a case is cumbersome to assemble and the cover cannot be removed to serve as a container for a separate tray. At present, when the box needs at least two buckles to realize the positioning fit of the cover body on the box body, a user needs to open two buckles respectively by both hands or open two buckles respectively by one hand when the cover is opened, and the operation is not simple enough, so that the user experience needs to be improved.
