    • To provide a spouted pouch that is simple in structure, being capable of dispersing any stress concentrated on a boundary area of spout seal portion, to thereby attain enhancements of pressure resistance and drop impact resistance. The spouted pouch is one having pouch main body (1) consisting of a bag formed by lamination of flexible films wherein the interspace between film edge portions as a seam is sealed by hot melt adhesion and having spout (3) fitted in the interspace between film edge portions of the pouch main body (1), the spout (3) sealed by hot melt adhesion together with the film edge portions, characterized in that on the external surface of the pouch main body (1), astride boundary area (6) between spout seal portion (2) and transformable film portion (5) facing the internal space of the pouch main body (1), there is provided stress dispersion piece (4) attached so as to partially cover both the spout seal portion (2) and the transformable film portion (5).
    • 为了提供结构简单的喷出袋,能够分散集中在喷口密封部分的边界区域上的任何应力,从而获得耐压性和耐滴落冲击性的增强。 喷出的袋子是一个具有袋主体(1)的袋子主体(1),其由通过层压柔性膜形成的袋组成,其中作为接缝的膜边缘部分之间的间隙通过热熔粘合而被密封并具有装配在膜之间的间隙中的喷口(3) 袋主体(1)的边缘部分,与薄膜边缘部分一起由热熔粘合而密封的喷口(3),其特征在于,在袋主体(1)的外表面上,跨越边界区域(6) 在与所述袋主体(1)的内部空间相对的喷口密封部(2)与可变形膜部(5)之间,设置有应力分散片(4),以部分地覆盖所述喷口密封部(2) 和可变形膜部分(5)。
