Abstract
A biaxially blow-molded bottle-shaped container (1) of synthetic resin includes a generally square cross-sectional body portion (2). A panel wall (3) for absorbing a reduced pressure generated in the bottle-shaped container is provided on a flat wall portion at each side of the body portion. Depressed cross grooves (5) are provided spaced apart in parallel in a ridge line portion between the adjacent panel walls (3, 3). The body portion may be cut-off at corners thereof to provide vertically elongated flat surfaces (4), and depressed cross grooves (5) may be provided spaced apart in parallel in each flat surface (4).
