Description

Food container with dual snap-in mechanism

The present invention relates to a food container, especially a food container with a double embedded card mechanism.

With the increasing number of double-income families or single office workers, the proportion of people who start a meal at home is gradually decreasing. Eating out has almost become an unavoidable diet for office workers. This situation has also led to the use of disposable lunch boxes. The rate remains high. Traditional disposable lunch boxes are usually bound by rubber bands so that the lid and the box body can be properly combined. However, due to the small size of the rubber bands, and often stained with oil, people do not eat when eating. There is no special storage of rubber bands, causing rubber bands to be easily forgotten and discarded. In addition, people have also found that when discarding the lunch box and the rubber band tied to it, stray dogs who rummage through the lunch box may be accidentally caught by the rubber band, and thus injured.

In view of this, some manufacturers have designed an interconnected structure on the box cover and the box body, so that the box cover can be directly fastened to the box body.
