Method for producing blow-molded containers and blow-molded container

A method for producing a blow-molded container with a closable mouth section, a side wall with a radially outermost surface at a first radial distance from a longitudinal center axis of the containers and a closed base, the method comprising the steps of:

• subjecting an injection-molded preform to a heat treatment;
• and molding the preform into a container by a blowing process so that material in an area of the side wall is molded by the blow-molding process so that at least three recessed grips are arranged along an outer periphery of the container, wherein between each pair of recessed grips are arranged at least two longitudinal ribs that are oriented in a longitudinal direction of the container and have a radially outermost surface at a second radial distance from the longitudinal center axis of the container, the second radial distance being smaller than the first radial distance along the same horizontal plane, the longitudinal ribs are separated from each other by a recess that also extends in the longitudinal direction, and wherein at least one peripheral rib, which is shaped to extend a greater distance in the circumferential direction of the container than in the longitudinal direction of the container, is located within each of the recessed grips.
