An improved collapsible container configured with a base member and at least one multiple cavity or compartment divider either permanently or removably attached to the base member at a pivot point. The multiple cavity divider is configured to close into a relatively flat portion that can be rotated about the pivot point and positioned against the base portion in a storage state, and the multiple cavity divider is configured to be expanded into an open position about the pivot point to create a number of separate cavities. Further, the base member is configured to provide support for the bottom of each of the cavities when the multiple cavity divider is in the expanded position, and the base member is configured to provide support for the multiple cavity divider when it is in the fold down or storage position.
