A foam the molded body with excellent flame retardancy. A foam molded body formed of a foam-molded resin composition containing a base resin and a flame retardant. An expansion ratio of the foam molded body is 1.1 to 9.0 times, the base resin contains polyolefin, and a blending amount of the flame retardant in the resin composition is 0.1 to 10% by mass.

A molding-forming method, a molding mold, and a molding production apparatus with which efficient burrs removal is possible without requiring a large apparatus. A molding production method includes, in addition to a molding being formed inside a mold, burrs formed around the molding are separated from the molding. After formation of the molding, air is blown inside the mold on at least a portion of the burrs formed around the molding to cool the same, a projecting member is projected toward the cooled burrs, and the burrs are separated from the molding. After pressing the burrs toward the projecting member by the air blowing, the burr is pressed toward the mold surface facing the projecting member by projection of the projecting member to separate the burr from the molding.

An apparatus including a conveyor track for upright containers, which is constituted by a horizontal, rotating conveyor belt, a vertical conveyor belt rotating in the same direction, which is arranged on one side of the horizontal conveyor belt and a vertical, fixed belt on the opposite side of the horizontal conveyor belt, where a distance between the vertical conveyor belt and the fixed belt is smaller than an outer diameter of the upright containers so that the upright containers rotate about a vertical axis as the upright containers pass between the rotating, vertical conveyor belt and the fixed, vertical belt and are laterally compressed so that the inner bags detach abruptly from the outer containers.

Provided is a manufacturing method for a double container that allows easy manufacturing with a molding device not significantly different from conventional devices and that can, at a lower cost than the processing cost of conventional technology, very easily and reliably form, in a comparatively rigid outer container and in a double container that allows, inside the outer container, capacity to be varied with respect to the amount of content, an opening for allowing external air to enter. When a pair of partial molds are brought near each other in order to form a split mold, at least part of the mating faces of the pair of partial molds forms a projection by sandwiching a small outer diameter portion of a parison, a gap that passes between the double container is created by cutting off the projection, and the gap is opened and expanded by screwing on a cap.

A separating system for separating individual container products from a frame assembly of plastic material, particularly polypropylene, has at least one stamping device (36) that at least partially separates the respective container product from a frame waste. By the stamping device (36) including a free fall body (52) separating the respective frame waste from the associated container product from an initial position during free fall, the separation can be carried out with very high speed (free fall) and additional mechanical components for applying a constraint force on the stamping body during the creating of the separating line can be omitted.

A mold body (10) for a blow mold (1). The mold body (10) has a bottom region (14), a shoulder region (13), a central region (15) and a separating plane (12). At least one mold cavity (11) has an inner wall (111) situated in the mold body (10). At least one temperature control channel (30) is arranged in the mold body (10). The at least one temperature control channel (30) is situated and/or positioned in the mold body (10) in such a way as to remove more heat from or supply more heat to a first region (112) of the inner wall (111) than a second region (113) of the inner wall (111) that is adjacent to the first region (112).

A hollow container producing device for producing a hollow container using a pair of parison sheets is provided. The hollow container producing device includes a pair of molds; an intermediate frame to be clamped to the pair of molds; and a transport unit that carries the intermediate frame and a pair of parison sheets to a position between the pair of molds, with the pair of parison sheets being respectively held on opposite sides of the intermediate frame.
