Abstract: A multi-layer nozzle for injection molding includes a nozzle housing, a valve stem, a stem guide, an insert, and a nozzle tip. The insert may comprise a 3D metal printed insert. In embodiments, a 3D metal printed insert may be configured to split and combine the flow of materials, which may form a multi-layered article, such as a preform. A method of using such a multi-layer nozzle to form articles is also disclosed.

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).

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°.
