  • Patent number: 10710292
    Abstract: An object of the present invention is to produce a double-sided carpet type skin-equipped hollow molded article so as to prevent degradation of aesthetic appearance of the hollow molded article. The double-sided carpet type skin-equipped hollow molded article includes: a hollow molded article main body made of a thermoplastic and having a front surface wall and a back surface wall; and skins integrally bonded to the respective front and back surface walls. A first skin bonded to the front surface wall is a napped-type skin. A second skin bonded to the back surface wall is a skin having a thickness smaller than a thickness of the first skin. A wall surface to which the first skin is bonded protrudes outward more than a wall surface to which the second skin is bonded in a parting line of the hollow molded article main body. The first skin has a large thickness and is a napped-type skin. Therefore, obtained is an effect that a nap raised after deburring and cutting masks a cut portion.
