Abstract: The intermediate stretched-blow molded container (1) comprises a biaxially stretched-blow molded hollow body (10) that comprises a container side wall (10a), at least one recess (101) that is formed in said container side wall (10a), that is off-center from the second vertical central plane (P2), and at least one convex and outwardly protruding deformable region (102) that is formed in the container side wall (10a). The maximum gripping dimension (DR) of the stretched-blow molded hollow body (10) measured next to and on one side of the convex and outwardly protruding deformable region (102) is smaller than the maximum dimension (DL) of the stretched-blow molded hollow body (10) measured next to and on the other side of convex and outwardly protruding deformable region (102).

Abstract: A primary blow mold for biaxially stretch blow molding a primary container in a double-blow molding process includes a mold cavity with a cylindrical upper molding portion and a bottom molding portion. The bottom molding portion has a sidewall; a concave transition wall where the transverse cross section of the mold cavity is the largest; and a bottom wall transvers to a central axis. In embodiments, the sidewall is not cylindrical and is an extension of the cylindrical upper molding portion, that forms a molding surface centered on the central axis; and the transverse cross section of the sidewall, measured in a plan perpendicular to the central axis, is the largest at the transition with the concave transition wall. The bottom molding portion defines an offset distance. In embodiments, an offset distance is at least 2 mm, and a slope angle of the sidewall is not less than 3°.
