Disclosed is a bottomed tubular bottle comprising:
an annular groove (20) which is formed so as to be circumferentially and radially recessed inward along the outer peripheral surface of a body of the bottle with the bottle axis as a center and which contracts and deforms the body in the axial direction of the bottle axis when the internal pressure is reduced,
wherein the annular groove (20) is formed in the shape of the letter V by two facing wall surfaces, and
a protrusion (25) is formed on at least one wall surface of the wall surfaces. |
