Abstract
Provided is a spouted pouch capable of improving the ability to suspend pouring liquid contents, the ease of adjusting a pouring force, and the ease of repouring. In the spouted pouch (10), a pouch body (20) has flow path control seal portions (22) formed on both left and right sides across an imaginary line A inside the outer edge seal portion (21). Assuming that a thickness dimension of the spout attachment base portion (31a) is taken as X, length dimension from the spout attachment base portion (31a) to the action point portion (22a) of flow path control seal portions (22) is taken as L, and a width dimension between the action point portions (22a) is taken as W, the thickness dimension X, the length dimension L, and the width dimension W are set so as to satisfy relationships of W/X=1.2 to 2.0 and L/X=0.3 to 1.5.
