Egg carton

[2][3] An egg carton can be made of various materials, including foamed plastics such as polystyrene foam, clear plastic or may be manufactured from recycled paper and molded pulp by means of a mechanized papier-mâché process.

[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.

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.
