Abstract

The invention discloses a lunch box. The lunch box comprises a shell and a liner arranged inside the shell, wherein first screw holes are formed in the bottom of the shell; second screw holes corresponding to the first screw holes are formed in the bottom of the liner; the liner and the shell are fixed via screws; rubber plugs inserted into the first screw holes are arranged at the ends, corresponding to the bottom surface, of the first screw holes; the bottom ends of the rubber plugs protrude out of the bottom surface of the shell. The lunch box has the beneficial effects that the rubber plugs are arranged in the screw holes and the bottom ends of the rubber plugs are arranged to protrude out of the bottom surface of the shell while the rubber plugs are utilized to prevent water, thus forming a non-slip mat, and through the arrangement, the rubber plugs simultaneously have two kinds of functions, so the structure of the lunch box is simplified and the non-slip rubber is unnecessary to be additionally arranged and glued to the bottom of the lunch box, thus reducing the cost and improving the assembly efficiency; besides, directly inserted into the screw holes, the rubber plugs can not fall off even if the rubber plugs are frequently worn.

Description

technical field [0001] The invention relates to the field of daily necessities, more specifically, to a lunch box. Background technique [0002] The lunch box is an important tableware commonly used in daily life, and it is used for carrying cooked food, and can provide cooked food in a working place or in the field within a certain period of time. [0003] Usually, the bottom surface of the lunch box needs to be provided with a non-slip pad to play a non-slip effect. The non-slip mat is usually made of rubber into a disc-shaped piece, and then bonded to the bottom of the lunch box. But this method is not only cumbersome to set up, it is often easy to stick crookedly, and it is easy to fall off after a long time of rubbing. Contents of the invention [0004] The technical problem to be solved by the invention is to provide a lunch box with simple structure and anti-skid. [0005] The object of the present invention is achieved through the following technical solutions: ...
