An egg carton (also known as an egg box in

eggs.[1]

Description

These

polystyrene foam, clear plastic or may be manufactured from recycled paper and molded pulp by means of a mechanized papier-mâché process.[1]

Origins

Before its invention, eggs were carried in egg baskets.[1] In 1906, Thomas Peter Bethell of Liverpool invented a predecessor to the modern egg box and marketed it as the Raylite Egg Box. He created frames of interlocking strips of cardboard, and packed these frames in cardboard or wooden boxes for transport by road or rail.[4]

In 1911, newspaper editor Joseph Coyle of Smithers, British Columbia, invented the egg carton, to solve a dispute between a local farmer, Gabriel LaCroix,[5] and hotel owner in Aldermere, near present-day Telkwa, in British Columbia,[6] over the farmer's eggs often being delivered broken.

In 1921, Morris Koppelman patented an improved version of the egg carton made from cut, folded and glued cardboard and functions similar to today's egg cartons. The patent emphasized the ability for it to fold flat after use, which is a feature no longer considered important.[7]

In 1931, American Francis H Sherman of Palmer, Massachusetts, patented an egg carton formed with pressed paper pulp that is recognizable as the modern egg carton used today.[8]

In the 1950s, British designer H.G Bennett, working for manufacturing company Hartmann, adapted the egg tray design to include a sealable lid, to allow for easy stacking and transportation of 6 or 12 eggs. These are the egg boxes still seen in supermarkets today.

In 1969, the United Industrial Syndicate (UIS) in Maine (a division of The Portland Company) patented an egg carton appears similar to Sherman's pressed paper pulp carton but has special pedestals formed into the carton to provide support for the weight of stacks of egg cartons and other strength related features and also an improved clasping closure feature. The three inventors listed on the filing are Walter H. Howarth, Gerald A. Snow, and Harold A. Doughty.[9]

Unlike many products, trademarks and advertisements for egg brands are usually printed on the food container itself rather than on a separate container (as with breakfast cereals).[1] This single-layer, distinctive packaging distinguishes among egg cartons from different producers or levels of quality on the retail shelf.

Sizes

Standard egg cartons have room for 10 or 12 eggs, but they can come in a variety of sizes, holding from one to 30 eggs.

Trays are usually used to store fresh eggs from farms or at farmers' markets. Plastic egg trays are also used by egg processors to wash and sanitize eggs. A cardboard sleeve or additional trays are used to protect eggs when using a tray format.
