An egg carton (also known as an egg box in British English) is a carton designed for carrying and transporting whole eggs. [1]
An egg carton (also known as an egg box in British English) is a carton designed for carrying and transporting whole eggs. [1]
These cartons have a dimpled form in which each dimple accommodates an individual egg and isolates that egg from eggs in adjacent dimples. This structure helps protect eggs against stresses exerted during transportation and storage by absorbing a lot of shock and limiting the incidents of fracture to the fragile egg shells. [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. [1]
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.
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.
Corrugated fiberboard or corrugated cardboard is a type of packaging material consisting of a fluted corrugated sheet and one or two flat linerboards. It is made on "flute lamination machines" or "corrugators" and is used for making corrugated boxes. The corrugated medium sheet and the linerboard(s) are made of kraft containerboard, a paperboard material usually over 0.25 millimetres (0.01 in) thick.
A box is a container with rigid sides used for the storage or transportation of its contents. Most boxes have flat, parallel, rectangular sides. Boxes can be very small or very large and can be used for a variety of purposes, from functional to decorative.
Paperboard is a thick paper-based material. While there is no rigid differentiation between paper and paperboard, paperboard is generally thicker than paper and has certain superior attributes such as foldability and rigidity. According to ISO standards, paperboard is a paper with a grammage above 250 g/m2, but there are exceptions. Paperboard can be single- or multi-ply.
Packaging is the science, art and technology of enclosing or protecting products for distribution, storage, sale, and use. Packaging also refers to the process of designing, evaluating, and producing packages. Packaging can be described as a coordinated system of preparing goods for transport, warehousing, logistics, sale, and end use. Packaging contains, protects, preserves, transports, informs, and sells. In many countries it is fully integrated into government, business, institutional, industrial, and for personal use.
Optical disc packaging is the packaging that accompanies CDs, DVDs, and other formats of optical discs. Most packaging is rigid or semi-rigid and designed to protect the media from scratches and other types of exposure damage.
Papier-mâché, frequently written as paper mache, is a composite material consisting of paper pieces or pulp, sometimes reinforced with textiles, and bound with an adhesive, such as glue, starch, or wallpaper paste.
A carton is a box or container usually made of liquid packaging board, paperboard and sometimes of corrugated fiberboard. Many types of cartons are used in packaging. Sometimes a carton is also called a box.
Cardboard boxes are industrially prefabricated boxes, primarily used for packaging goods and materials. Specialists in industry seldom use the term cardboard because it does not denote a specific material. The term cardboard may refer to a variety of heavy paper-like materials, including card stock, corrugated fiberboard, and paperboard. Cardboard boxes can be readily recycled.
A susceptor is a material used for its ability to absorb electromagnetic energy and convert it to heat. The electromagnetic energy is typically radiofrequency or microwave radiation used in industrial heating processes, and also in microwave cooking.
A converter is a company that specializes in modifying or combining raw materials such as polyesters, adhesives, silicone, adhesive tapes, foams, plastics, felts, rubbers, liners and metals, as well as other materials, to create new products.
Molded pulp or molded fiber is a packaging material, that is typically made from recycled paperboard and/or newsprint. It is used for protective packaging or for food service trays and beverage carriers. Other typical uses are end caps, trays, plates, bowls and clamshell containers.
Food packaging is a packaging system specifically designed for food and represents one of the most important aspects among the processes involved in the food industry, as it provides protection from chemical, biological and physical alterations. The main goal of food packaging is to provide a practical means of protecting and delivering food goods at a reasonable cost while meeting the needs and expectations of both consumers and industries. Additionally, current trends like sustainability, environmental impact reduction, and shelf-life extension have gradually become among the most important aspects in designing a packaging system.
Package cushioning is used to protect items during shipment. Vibration and impact shock during shipment and loading/unloading are controlled by cushioning to reduce the chance of product damage.
The folding carton created the packaging industry as it is known today, beginning in the late 19th century. The process involves folding carton made of paperboard that is printed, laminated, cut, then folded and glued. The cartons are shipped flat to a packager, which has its own machinery to fold the carton into its final shape as a container for a product. An example of such a carton is a cereal box.
Disposable food packaging comprises disposable products often found in fast-food restaurants, take-out restaurants and catering establishments. Typical products are foam food containers, plates, bowls, cups, utensils, doilies and tray papers. These products can be made from a number of materials including plastics, paper, bioresins, wood and bamboo.
Ecologic Brands Inc. is a United States company that specializes in creating eco-friendly packaging solutions for consumer products. The products are made from sustainable materials and are designed to be recyclable or compostable. The company also provides branding and marketing services to help companies promote their environmentally conscious products.
Cardboard is a generic term for heavy paper-based products. The construction can range from a thick paper known as paperboard to corrugated fiberboard which is made of multiple plies of material. Natural cardboards can range from grey to light brown in color, depending on the specific product; dyes, pigments, printing, and coatings are available.
Shelf-ready packaging (SRP) and retail-ready packaging (RRP) refers to the packaging of a product so that it is delivered to a retailer in packaging which is optimized for efficient stocking and sale.
A clamshell is a one-piece container consisting of two halves joined by a hinge area which allows the structure to come together to close. Clamshells can be made to be reusable and reclosable or can be sealed securely.
Closed Loop Box Reuse, is the process by which boxes or other containers are reused many times. It is a form of reusable packaging.
