In packaging, a Bag-In-Box or BIB is a type of container invented by William R. Scholle in 1955 for the storage and transportation of liquids. It consists of a strong plastic bag seated inside a cardboard box. The bag is filled by the manufacturer with the desired liquid, then sealed, and then the box is sealed.
For use, the customer tears open a pre-cut window at one end of the box and connects a nozzle to a built-in port on the bag to pump out its contents.
The BIB has many common commercial applications. The most ubiquitous is the use of BIBs to supply syrup to soft drink fountains in the foodservice context.
The user is generally advised to not take the bag out of the box, as the bag alone may not be able to contain the internal pressure from its contents and could explode.
