Abstract:
An external button lunch box includes a box body and a box lid. One or both sides of the butt edge of the box lid and the box body are connected through longitudinal ridges and slots. The protruding rib is located on the inside of the box cover, and the slot is located on the outside of the box body. The external buckle type lunch box provided by the utility model is provided with a latching groove on the outer side of the box body, and a convex rib is provided on the inner side of the lid corresponding to the latching groove. After the latching groove and the convex rib cooperate, the box can be realized. A stable connection between the body and the box lid; on the basis of the cooperation of the slot and the convex rib, a further vertical matching edge can be added, so that the vertical matching surfaces in contact with each other can achieve a better sealing effect, which is consistent with the existing technology Compared with the lunch box with horizontal surface, the sealing is better.
