PROBLEM TO BE SOLVED: To improve a touch feeling on side seal parts without forming a notch in a pouch container comprising a pair of body part sheets, a bottom part sheet and a top face sheet with a spout.SOLUTION: A pouch container comprises: a pair of body part sheets bonded at both width-wise sides; a bottom part sheet bonded to lower parts of the respective body part sheets; a top face sheet bonded to upper parts of the respective body part sheets; and a spout attached to the top face sheet. Side seal parts 22 are formed vertically extending at both side edge parts of the pair of body sheets as joint parts. In the side seal parts 22, folding lines 24 is formed to define folding positions in a width-wise middle area. Each of the folding lines 24 includes: an intermediate line part 24a extending vertically; and inclined line parts 24b, 24c extending vertically at least from one of upper and lower ends of the intermediate line parts 24a to outer side edge parts 25 of the side seal parts 22.SELECTED DRAWING: Figure 3 【課題】一対の胴部シール、底部シートおよびスパウト付き天面シートを備えるパウチ容器において、切込みを形成することなくサイドシール部の手触り感を改善する。【解決手段】幅方向の両側で接合された一対の胴部シートと、前記各胴部シートの下部に接合された底部シートと、前記各胴部シートの上部に接合された天面シートと、前記天面シートに装着されたスパウトと、を備えるパウチ容器であって、一対の胴部シートの両側縁部には接合部であるサイドシール部２２上下方向に沿って延伸形成されている。サイドシール部２２には幅方向中央領域での折れ曲がり位置を画定する折り曲げ線２４が形成される。折り曲げ線２４は、上下方向に沿って延びる中間線部２４ａと、中間線部２４ａの上端および下端の少なくとも一方からサイドシール部２２の外側縁部２５まで上下方向に対して傾斜して延びる傾斜線部２４ｂ，２４ｃとを含む。【選択図】図３
