PROBLEM TO BE SOLVED: To provide a paper container formed of a waste paper pack to be used as an accessory case. SOLUTION: The paper container is formed of a waste paper pack by cutting a head of the paper pack including a peripheral wall consisting of four sidewalls in a peripheral direction on a bottom wall. The frame device to be mounted on an opening rim formed by cutting the paper container comprises an outer frame and an inner frame. While the outer frame is fitted over the inner frame, a holding space for holding the opening rim of the paper container is formed between an inner peripheral wall of the inner frame and an outer peripheral wall of the outer frame. The outer peripheral wall of the outer frame is equipped with inward locking ribs on inner faces of at least a pair of opposite walls, while the inner peripheral wall of the inner frame is equipped with outward locking ribs on outer faces of at least a pair of opposite walls. While the outer frame is fitted over the inner frame, the inward locking ribs and the outward locking ribs face across a vertical interval, so that the holding space is bent by the inward locking ribs and the outward locking ribs. |
