A heat-resistant hollow cylindrical container comprising a neck, a shoulder, an upper body, a middle body provided with pressure reduction absorbing panels, and a lower body including a bottom wall, wherein said pressure reduction absorbing panels are arranged symmetrically relative to a central axis of the container, each of said pressure reduction absorbing panels is located inside an imaginary outer periphery of the cylindrical shape of the container, and each of said pressure reduction absorbing panels is provided with at least a pair of protuberances to be hooked by a finger. The middle body is provided with two pressure reduction absorbing panels arranged symmetrically respective to the central axis of the container. Said protuberances form a gap therebetween, and have a width and a height so sized as to allow a finger tip to be placed into the gap. Said middle body is also provided with groove-shaped ribs arranged along the upper and lower edges of thereof to absorb changes in an internal pressure in the container. Each of said groove-shaped ribs has an eccentric profile with a depth gradually decreasing to become nil in one of the lateral sides of the body.
