The yarn density is the highest on the line connecting the center of the corner radius and the center of curvature of the corner radius, and gradually increases toward the line connecting the both ends of the corner radius and the center of curvature of the corner radius. Inextensible structure of the box-shaped container like molded article comprising a facing layer comprising a fabric, characterized in that has fence.

する箱形容器状成形品の成形方法。2. A method for molding a box-shaped container-shaped molded product having a flat quadrangular shape and each corner having curved surfaces, which comprises a thermoplastic nonwoven fabric as a core material or an inorganic fiber nonwoven fabric made of a thermoplastic resin as a matrix. Includes a step of heat-softening, a step of stacking a woven fabric of non-stretchable fibers as a surface material on the heat-softened core material and press-molding, and the material holding force of a clamp that holds the surface material during the press-molding step Is the strongest in the part corresponding to the line connecting the center of the corner radius and the center of curvature of the corner are in each corner of the molded product, and gradually gradually approaches the part corresponding to the line connecting the ends of the corner are and the center of curvature of the corner are. The box-shaped container is characterized in that it becomes smaller and is adjusted to be almost free in parts other than the corner radius. Molding method of goods.
