Strongbox


A safe (also called a strongbox or coffer) is a secure lockable box used for securing valuable objects against theft and/or damage from fire. A safe is usually a hollow cuboid or cylinder, with one face being removable or hinged to form a door. The body and door may be cast from metal (such as steel) or formed out of plastic through blow molding. Bank teller safes typically are secured to the counter, have a slit opening for dropping valuables into the safe without opening it, and a time-delay combination lock to foil robbers/and or thieves. One significant distinction between types of safes is whether the safe is secured to a wall or structure or if it can be moved around. A less secure version (only suitable for petty cash) is usually called a cash-box.

In 1835, English inventors Charles Chubb and Jeremiah Chubb in Wolverhampton, England, received a patent for a burglar-resisting safe and began a production of safes. The Chubb brothers had produced locks since 1818. Chubb Locks was an independent company until 2000 when it was sold to Assa Abloy.

On November 2, 1886, inventor Henry Brown patented a "receptacle for storing and preserving papers." The container was fire retardant and accident resistant as it was made from forged metal. The box was able to be safely secured with a lock and key and also able to maintain organization by offering different slots to organize important papers.

Specifications for safes include some or all of the following parameters:

It is often possible to open a safe without access to the key or knowledge of the combination; this activity is known as safe-cracking and is a popular theme in heist films.
