  • Laminated structure and method for manufacturing the same
    Patent number: 7744983
    Abstract: The laminated structure includes a lightweight and shape-retaining foamed resin base member, an outer circumference frame integrally laminated on the reverse side of the foamed resin base member along the outer circumference of an article, and bridging ribs connecting between respective points on the outer circumference frame. Accordingly, the present invention provides a lightweight laminated structure with low cost by reducing the amount of the resin used, since the molded synthetic resin outer circumference frame and bridging ribs have small projection areas.
