[Problem] To realize a predetermined 'aseptic level of the containers' without introducing a container sterilizing machine and to reduce the burden for adjusting the temperature of the preform. [Means for Solution] A metal mold for molding, wherein a space width (t) of at least the body portion in the space width for forming a thickness of from the body portion to the bottom portion of the preform is set to lie in a range of 1.18 to 2.11 times as great as a space width (t) for forming a thickness of an upper end portion of the mouth portion of the preform. At the time of the compression molding, the preform is taken out in the state of a high temperature from a compression-molding machineand is fed to a bottle-producing unit C while maintaining the state of a high temperature. Further, the inner surfaces of a clean box I in which the units are placed and the outer surfaces of the units are sterilized, and the interior of the clean box I maintains a positive-pressure state with the filtered clean air. The bottle-producing unit C and a filling/sealing unit D are neighboring and directly coupled to each other in the same clean box, and are partitioned by a WBZ

System for aseptically filling a container with a beverage or food

The invention also provides for an apparatus for feeding molten resin, wherein the apparatus includes holding units each having a respective holding portion that is opened and closed to hold a molten resin that is discharged from an extrusion port of a die head of an extruder and is cut by a cutter while moving on a track, in which, after the respective holding portion transfers the molten resin from the extrusion port to a female mold, a side of the respective holding portion is opened and the molten resin is fed down to the female mold in a compression-molding machine, wherein a plurality of longitudinal grooves extending up and down are formed in an inner circumferential surface of the respective holding portion that holds the molten resin.

Apparatus for feeding molten resin

To provide a metal mold for forming a preform decreasing the hitting of metal molds at a portion where a slide insert metal mold and a cavity metal mold undergo the sliding yet maintaining the pressure. The metal mold () for forming the preform includes a slide insert metal mold () split into at least two for forming at least a nozzle portion of the preform, wherein a pressure is maintained by using a fitting portion which includes a preform-forming portion of the slide insert metal mold () coupled together from the split state and a cavity metal mold (). Auxiliary fitting portions () where the slide insert metal mold () and the cavity metal mold () undergo the sliding is formed at a position of not forming the preform separate from the fitting portion that includes the preform-forming portion.

Metal mold for compression forming

Apparatus for feeding molten resin includes a holding unit that moves on a track and at least a pair of holders capable of holding and releasing the molten resin accompanying the opening and closing of the holding unit. A base portion is utilized for supporting the holders so as to be opened and closed and for holding the molten resin together with the holders. The molten resin discharged from an extrusion-forming machine and cut by a cutter is held by the holding unit, and it fed from the holding unit to a female mold of a compression-0molding machine. At the time of cutting the molten resin, a cutter mark is formed by the cutter on a cut surface of the molten resin.
