Abstract: A heat-resistant and biaxially stretched blow-molded plastic container includes a base movable to accommodate vacuum forces generated within the container and thereby decrease the volume of the container. Embodiments of a container include a push-up portion, and first and second parting lines that are separated from one another by a gap and that extend on opposite sides of the push-up portion. Embodiments of such a container exhibit one or more of the following: (a) a distance between each parting line and the center of the base is not more than 20 mm; (b) a distance between the two parting lines is not more than 40 mm; and/or (c) a distance between the two parting lines is less than 50% of the transverse dimension of the base measured between the two outermost points of the parting lines. Methods for blow molding heat-resistant plastic containers are also disclosed.

Abstract: A container (1) and a screwable closure (2) comprising a hollow body (11) and a neck finish (10) terminated by a wide-mouth opening (100). Said neck finish comprises a neck support ring (102) and a neck portion (101) extending between the wide-mouth opening (100) and the neck support ring (102). The neck portion (101) comprises an upper portion (1010) and a reinforced lower portion (1011). The inner face (1011 b) of the reinforced lower portion (1011) is transitioning to the inner face (1010b) of the upper portion (1010) along a transition step (1011c) in such a way that said reinforced lower portion (1011) is thicker than the upper portion (1010) at least in a top part of the reinforced lower portion (1011). The neck support ring (102) is below the removable closure (2).
