A device for producing plastic containers (10) by means of a molding, filling and sealing process is disclosed, at least consisting of a molding device (16) having individual molding tools (18), which can be moved repeatedly relative to one another from an open receiving position into a molding sealing position, and an extrusion unit (12), which can be used to insert at least one extruded plastic hose (14) into the open receiving position of the molding tools (18), which is characterized in that a traversing unit (20) can be used to move the extrusion unit (12) in conjunction with each extruded plastic hose (14) in opposite directions with respect to the molding device (16), which is stationary in every position of the molding tools (18).

A production apparatus of a two-layer preform including an inner layer preform and an outer layer preform includes: an outer layer cavity mold for injection-molding the outer layer preform. A bottom surface of the outer layer cavity mold is provided with a protrusion for separating the inner layer preform disposed in the outer layer cavity mold from the bottom surface.

A hollow article is molded in a state where an inner surface of a neck portion including an inner screw portion is held by an inner neck mold, and then, the hollow article is demolded from the inner neck mold by inserting an ejection rod into the hollow article to be engaged with an inner surface of the hollow article and rotating the hollow article together with the ejection rod.

Systems and methods for making a reduced material container (105) are provided that hold a preform (130) adjacent to an open end (165) of the preform (130), stretch the preform (130), close a mold (110, 120) about the stretched preform (175) to form a truncated preform (185), and introduce a pressurized fluid (160) into the truncated preform (185) to expand the truncated preform (185) and form the reduced material container (105). A stretch rod (125) can be inserted into the preform (130) to mechanically stretching the preform (130). The mold (110, 120) accepts the preform (130) at a first end (135) thereof, has an open state and a closed state, and the closed state forms a cavity (140) defining an internal surface (145) having a second end (150) located remotely from the first end (135). A first length (155) is defined by a distance between the first end (135) and the second end (150), the stretch rod (125) mechanically stretching the preform (130) to a second length (170), the second length (170) being greater than the first length (155).

Disclosed is a method for producing at least one molded, filled and sealed container product (10) comprising at least the method steps listed below: extruding a hose (32) by means of an extrusion device (12) using supporting gas in vertical extrusion direction in a preforming position; sealing the hose (32) at its lower end and cutting it at its upper open end; transporting of the parison (22) thus cut to length by means of a gripper device (20) in linear transport direction transverse to the extrusion direction from the preforming position into an opened molding tool (18); transferring the parison (22) into the opened molding tool (18) by means of the gripper device (20) in a main forming position; sealing the molding tool (18) for further forming of the parison (22) by a pressure gradient; filling and sealing the parison (22); and returning the gripper device (20) to the preforming position for a repeated sequence of the above method steps

A blow core mold unit includes a first core member configured to be loosely fitted to a neck portion of a preform, a second core member provided around the first core member and in contact with a neck mold, and a third core member provided in a space portion formed between the first core member and the second core member, and the blow core mold unit has a second supply flow path for supplying a high-pressure fluid into the space portion.

Described are a mold and molding process for manufacturing devices and containers that are scalable, modular, and lockable laterally and vertically with other like devices or containers. The mold is formed with a cup mold and top end mold sections specially designed to allow for molding and demolding a container with an undercut. The cup mold includes, on a vertical wall, one or more undercuts. Multiple undercuts may further form tongues with undercuts each of which forms a groove with undercuts on the molded article, and/or one or more grooves with undercuts each of which form a tongue with undercuts in the molded article. Molding and Demolding of the article with undercuts is further enabled by utilizing an improved method of molding said article with an undercut, and demolding said article from the mold once it is molded, by improvements to each stage of the molding process, including the preform stage, the conditioning station stage, the blow stage and the release stage.

There is provided a resin container manufacturing apparatus configured to stretch a preform disposed in a stretch blow molding mold by a stretching rod and stretch the preform by introducing blow air into the preform so as to form a resin container. The resin container manufacturing apparatus includes detection means for detecting an actual position of the stretching rod inserted into the preform, and supply control means for controlling a supply state of the blow air based on a detection result of the detection means.
