Lunchbox
food container

A lunch box (or lunchbox) is a hand-held container used to transport food, usually to work or to school. It is commonly made of metal or plastic, is reasonably airtight and often has a handle for carrying.
In the United States
In the United States a lunchbox may also be termed a lunch pail, lunch bucket, or lunch tin, either as one or two words.
The concept of a food container has existed for a long time, but it was not until people began using tobacco tins to carry meals in the early 20th century, followed by the use of lithographed images on metal, that the containers became a staple of youth, and a marketable product. It has most often been used by schoolchildren to take packed lunches, or a snack, from home to school. The most common modern form is a small case with a clasp and handle, often printed with a colorful image that can either be generic or based on children's television shows or films. Use of lithographed metal to produce lunch boxes from the 1950s through the 1980s gave way to injection-molded plastic in the 1990s.
A lunch kit comprises the actual "box" and a matching vacuum bottle. However, popular culture has more often embraced the singular term lunch box, which is now most commonly used.
With increasing industrialization resulting in Americans working outside the home in factories, it became unfeasible to go home to lunch every day, thus it was necessary to have something to protect and transport a meal.
