<p>Disclosed is a closed-bottom cylindrical bottle that is provided with an annular-shaped groove centered on the bottle axis that is radially inwardly recessed and circumferentially formed in the peripheral surface of the body, and that contracts and deforms the body in the axial direction of the bottle when the internal pressure decreases. The annular-shaped groove is recessed and formed by a first wall surface disposed on the opening side and a second wall surface disposed on the bottom side. The body sandwiches the annular-shaped groove and is formed so that the outer diameter of the bottom side is larger than the outer diameter of the opening side.</p> |
