Container (data structure)

A container is any receptacle or enclosure for holding a product used in storage, packaging, and transportation, including shipping.
Things kept inside of a container are protected on several sides by being inside of its structure. The term is most frequently applied to devices made from materials that are durable and are often partly or completely rigid.

A container can also be considered as a basic tool, consisting of any device creating a partially or fully enclosed space that can be used to contain, store, and transport objects or materials.

History

Humans have used containers for at least 100,000 years, and possibly for millions of years.Clive Gamble, ''Origins and Revolutions: Human Identity in Earliest Prehistory'' (2007), p. 204. The first containers were probably invented for storing food, allowing early humans to preserve more of their food for a longer time, to carry it more easily, and also to protect it from other animals. The development of food storage containers was "of immense importance to the evolving human populations", and "was a totally innovative behavior" not seen in other primates. The earliest containers were probably objects found in nature such as hollow gourds, of which examples have been found in cultures such as those of the Tharu people, and native Hawaiian people. These were followed by woven baskets, carved wood, and pottery.

Containers thereafter continued to develop along with related advances in human technology, and with the development of new materials and new means of manufacture. Early glass bottles were produced by the Phoenicians; specimens of Phoenician translucent and transparent glass bottles have been found in Cyprus and Rhodes generally varying in length from three to six inches. These Phoenician examples from the first millennium BC were thought to have been used to contain perfume. The Romans learned glass-making from the Phoenicians and produced many extant examples of fine glass bottles, mostly relatively small. By the beginning of the eighteenth century, sizes for retail containers such as glass bottles had become standardized for their markets.Warren Belasco, Roger Horowitz, ''Food Chains: From Farmyard to Shopping Cart'', pp. 98–99.

In 1810, Frenchman Philippe de Girard came to London and used British merchant Peter Durand as an agent to patent his own idea for a process for making tin cans. The canning concept was based on experimental food preservation work in glass containers the year before by the French inventor Nicholas Appert. Durand did not pursue food canning, but, in 1812, sold his patent to two Englishmen, Bryan Donkin and John Hall, who refined the process and product, and set up the world's first commercial canning factory on Southwark Park Road, London. By 1813 they were producing their first tin canned goods for the Royal Navy.

For transportation of goods on a larger scale, larger containers remained a problem, as customs officials inspecting imports had to deal with a lack of standardization in this field, and because predominantly wooden containers in use well into the twentieth century were prone to leaking or breaking. The standardized steel shipping container was developed in the 1950s, and quickly became ubiquitous for the large-scale transportation of commercial goods.

Towards the end of the Twentieth century, the introduction of computer-aided design made it possible to design highly specialized containers and container arrangements, and also to make form-fitting labels for containers of unusual shapes.Geoff A. Giles, ''Design and Technology of Packaging Decoration for the Consumer Market'' (2000), p. 82: "Container designers also found that shrink sleeves gave them new-found freedom to design containers that until then had been viewed as impossible to decorate".

Modern characteristics

A number of considerations go into the design of modern containers:

Variety

Practical examples of containers are listed below.

* Ceramic cylindrical vessels including:
** Ancient vessels, including Amphoras, Kvevri, Pithos, and Dolium
** Bottles, similar to a jar in being traditionally symmetrical about the axis perpendicular to its base and made of glass
** Jars, traditionally cylindrical and made of glass
** Jug
* Cylindrical vessels including:
** Barrels, made of wooden staves bound by rope, wooden or metal hoops.
** Cans, traditionally cylindrical and sheet-metallic.
** Drums, similar to a can but definitely cylindrical and not necessarily metallic
** Tub
* Rectilinear vessels including:
** Boxes
** Crates, a box or rectilinear exoskeleton, designed for hoisting or loading
** Wooden boxes
** Lift-vans
** Corf
** Dumpsters
** Certain waste containers
* Flexible containers including:
** Bags, such as shopping bags, mail bags, sick bag
** Luggage, including satchels, backpacks, and briefcases
** Packets
** Gunny sacks, flour sacks
** Wallets
* Shipping containers, including:
** Corrugated boxes, made of corrugated fiberboard
** Intermodal containers, a.k.a. ship container or cargo container
*** Twenty-foot equivalent units, an industry standard intermodal container size
** Intermediate bulk containers
** Unit load devices, similar to a crate
** Flexible intermediate bulk containers
