Definitions
- the present invention relates to a filling and packaging machine in which a container is filled with contents such as a soft drink and covered with a lid, and more specifically, a sheet-like lid material is suspended from a disc-like lid body and a lid body peripheral portion.
- the present invention relates to a filling and packaging machine including a next lid forming device.
- a bottle-shaped synthetic resin container supplied in an arbitrary direction is set up so that its upper end opening faces upward, and is supplied to a subsequent process.
- a standing device a filling device that fills a container supplied from a container standing device, a lid supply device that covers an upper end opening of the container filled with the content with a substantially U-shaped lid, and Filling and packaging machines equipped with a sealing device that heat-seals the lid to the upper end opening of the container are known (for example, see Japanese Examined Patent Publication No. 491-37977).
- the bottle-shaped synthetic resin container may have a mouth directly on the container opening and drink the contents after the lid has been peeled off
- a lid composed of a lid configured to protect the portion, that is, a disc-shaped lid body that covers the opening at the upper end of the container, and a skirt portion that is suspended from the periphery of the lid body (a substantially U-shaped lid in cross section) Is used.
- the aluminum foil is heat-sealed by paying attention to the excellent formability and shape retention of the aluminum foil.
- this lid material is punched out into a disk-shaped lid and formed into a U-shaped cross-section lid immediately after punching, and a molded U-shaped cross section
- a lid supply device for supplying and covering a lid at the opening of a container being transported is known (see, for example, Japanese Patent Laid-Open No. 63-212019).
- a metal detector cannot be used in a container having a lid material based on such an aluminum stay layer, so that nails, There is a problem that it is not possible to detect metals that may be mixed in such as kiss needles, broken pieces of molded product cutting blades, bolts and nuts, wires, and springs. Further, these containers having an aluminum lid have the disadvantage that the aluminum lid and the synthetic resin container body such as polystyrene need to be separately collected and are inferior in recyclability.
- a cover made of a laminated film only of a synthetic resin layer not having an aluminum stay layer is provided by the present inventors. It has been proposed (see, for example, JP-A-2002-225902).
- the lid is a lid composed of a combination of synthetic resin layers only, and the lid shape is also highly complete.
- the lid material in order to mold the lid, the lid material must be molded by heating.
- the lid molding device and the filling packaging machine should be a continuous process from the viewpoint of temperature control of the heating zone for heating the lid material. There was a problem that was difficult.
- the present inventors have conducted research on the lid material and succeeded in developing a synthetic resin lid material that can be molded by cold drawing (for example, specially Open 2004-74794), and a container using a synthetic resin lid material capable of forming a lid material by vigorous cold drawing, that is, a resin container and a lid fixed to the resin container.
- Polystyrene (HIPS; High Impact Polyst yrene) or impact resistance It is produced by cold-molding a cold-molding resin sheet having a base material layer containing a polystyrene-based resin containing a composition composed of restyrene and a styrene-butadiene copolymer, and has a shape retention property. (See, for example, JP-A-2004-75196).

- the sealed container P on the container table is gradually raised by the lifting mechanism described above.
- the lid skirt P-22 of the closed sealed container P is pressed into the molding hole formed in the cylindrical female mold F-141.
- the lid upper surface P- 21 is in contact with the bottom of the insertion recess F-148 of the extrusion piston F-142, and the heated lid skirt P-22 is inserted into the insertion recess F-148 of the extrusion piston F-142, and the lid skirt P-22
- the gear F-147 is rotated by the driving force of the toothed belt F-153, and the extrusion piston F-142 is rotated via the piston rod F-145.
- the rotational force acts on the sealed container P by the rotation of the piston F-142, but the container body P-1 is sealed by the container body P-1 because the rotation is restricted by the container holder F-132.
- a synthetic resin container filled with the contents is covered with a lid on which a synthetic resin sheet-like lid is also formed, so that a conventional aluminum staying layer is formed.
- a product container equivalent to a product container using a cover material as a base material can be obtained.
