The safety deposit box in "Whatever the Case May Be"

A safety deposit box, also known as a safe deposit box, is a type of safe usually located in groups inside a bank vault or in the back of a bank or post office. It usually holds things such as valuable gemstones, precious metals, currency, or important documents such as wills or property deeds that a person might feel afraid to leave at home due to fear of theft, fire, or flood. In the typical arrangement, a renter pays the bank a fee for the use of the box, which can be opened only with production of the assigned key, the bank's master key, the proper signature, or perhaps a code of some sort.
