<p>PROBLEM TO BE SOLVED: To prevent a bottle from irregularly deforming and facilitate deformation of a basic face lower part for improving effects for absorbing reduced pressure by connecting an end of a reduced pressure absorbing panel having the basic face gently protruding outward to a cylindrical bottle via a tilted face and also by forming narrow recesses from the basic face toward the tilted face. SOLUTION: In this plastic bottle formed with an approximately flat reduced pressure absorbing panel 2 on a wall face of a cylindrical bottle body 1, two reduced pressure absorbing panels 2 are formed on a face opposite to a handle 3 of an upper body of the cylindrical bottle body 1 so that the panels are largely notched approximately flatly from shoulders wherein they are generally formed of basic faces 21 gently protruding outward. In order to smoothly connect the basic faces 21 with the cylindrical bottle body, a lower end of the basic face 21 is connected to a cylindrical face 11 on a lower part of the bottle body 1 via a tilted face 22. Further a narrow recess recessed from the basic face 21 is formed from a middle height of the basic face 21 toward the tilted face 22.</p> |
