Convertible box

Described here are convertible storage containers and methods of making and using them. These storage containers may be useful for packing goods, particularly packing fresh fruit and vegetables. The convertible storage containers typically comprise a plurality of non-convertible sides which assemble to form a storage cavity, a convertible side, and a plurality of conversion connectors that may secure the convertible side in a first position or a second position. When the convertible side is secured in the first position, the convertible storage container is a box having an attached top. When the convertible side is secured in the second position, the convertible storage container is an open-top display box. The convertible side may be secured by a self-securing conversion connector. Further, these convertible storage containers may be stackable, and may comprise alignment guides. Methods of making convertible storage containers are also described.
