PROBLEM TO BE SOLVED: To provide a bag-shaped skin-integrated foam molding in which the number of parts is not increased, and the productivity is not lowered without a jig device, and the quality is stable even if the spring force of skin pieces is different, and even if the skin pieces with high spring force are used, and to provide its manufacturing method.SOLUTION: A bag-shaped skin-integrated foam molding is formed of a flat cylindrical part 4 by facing design surfaces 3a of tongues 33 protruded from main parts 31 of two skin pieces 3 and seaming both side edges of the two-folded tongues together, and includes a bag-shaped skin 2, and a foamed body integrally foamed and molded by housing the flat cylindrical part folded from a bottom portion 231 formed by a main part in the inside 20 of a bag-shaped skin and injecting a foaming ingredient in the inside of the bag-shaped skin from a nozzle 40. A seam line for forming a bottom part 23 is sutured in the main part of the two skin pieces by leaving a bottom part area of the bag-shaped skin having the flat cylindrical part. In addition to this, a striped frangible part 34 for facilitating folding is provided in a part E where the tongue of at least one skin piece bends from the bottom face portion.
【課題】部品点数を増加させず、また治具装置なしで生産性を落とすことがなく、表皮片の弾発力が違っていても、高い弾発力のある表皮片を使用しても、品質が安定した袋状表皮一体発泡成形品及びその製造方法を提供する。【解決手段】二つの表皮片3の主部31から張り出す舌片部33の意匠面3aを対向させ、二枚重ねにした舌片部の両側縁沿いを縫い合わせて扁平筒部4を形成し、且つ袋状表皮2と、主部がつくる底面部分231から折り曲げられる扁平筒部を袋状表皮内20に収め、その筒口40から袋状表皮内へ発泡原料を注入して一体発泡成形された発泡体と、を備える袋状表皮一体発泡成形品において、扁平筒部が在る袋状表皮の底面部域を残して、二つの表皮片の主部に、底面部23を形成する縫目ラインが縫合されるのに加え、少なくとも一方の表皮片の舌片部が底面部分から折れ曲がる部位Eに、折り曲げを容易にする筋状の脆弱部分34が設けられた。【選択図】図3
