Disclosed is a handy bottle capable of absorbing deformation strain caused by variation of capacity, which is easy for lifting up and carrying because of its recessed portions for gripping and is excellent in dropping strength and capable of preventing the buckling phenomenon while maintaining moldability and lightweight property as well as a process for producing the handy bottle. A typical example of the handy bottle is featured by having the recessed portions for gripping on both side of a body portion thereof, a minimum distance L between the deepest portions of the recessed portions for gripping being 50% or less of the diameter D of the body portion, i.e. L/Dnull50%, and a shape in diametric cross section of the recessed portions being almost bilaterally symmetrical to a line connecting the deepest portions and a central axis of the body portion. The process for producing the handy bottle is featured by allowing movable inserts capable of molding the recessed portions for gripping to be on standby in the position at 2.0null2.6 times null of the central diameter R of a preform from the central axis of the preform, i.e. nullRnull(2.0 to 2.6), and allowing the movable inserts to proceed toward the deepest portions of the recessed portions for gripping in the course of blow molding.
