  However, in the filling and packaging machine described in Patent Document 1, since the plug is attached to the packaging material in the initial stage, the influence of the plug protruding from the band-shaped packaging material and the flexibility of the band-shaped packaging material are impaired. Then, there has been a problem that a conveyance failure or a molding defect occurs in the subsequent belt-shaped packaging material conveyance means or packaging material molding means. In addition, the filling and packaging machine described in Patent Document 2 is for inserting a plug by a plug supply unit into a hole opened by the hole punching unit, but its positioning is very difficult, and the device It itself was very complex. Furthermore, in the conventional filling and packaging machine, when using an aseptic filling method for obtaining a sterile product that can be stored for a long time by sterilizing the contents and the packaging material in advance, the stopper of the container is in contact with the liquid contents. Therefore, there is a problem that the mouth plug must be sterilized in advance in addition to the strip-shaped packaging material. Moreover, since the shape of the mouth plug is complicated, it is very difficult to completely sterilize the mouth plug in a short time. A large-scale sterilization means is required, and there is also a problem that it is difficult to obtain a satisfactory aseptic product even if the sterilized mouth plug is used.

  An object of the present invention is a compact machine capable of easily and surely mounting a plug without causing defective conveyance or molding, and can easily produce a sterile product with a plug. It is to provide a filling and packaging machine.

  As a result of diligent research to solve the above problems, the present inventors have found that the mouthpiece is not attached to the band plate-like packaging material at the initial stage before being formed into a flat cylindrical shape, but is formed into a flat cylindrical shape. By attaching the stopper, it is possible to prevent poor conveyance and defective molding into the cylindrical packaging material, and the mouth plug is connected to the outer surface of the flat cylindrical packaging material in a state where it does not communicate with the inside. By attaching, the plug can be easily and reliably attached. Furthermore, since the plug does not come into contact with the liquid content, it is not always necessary to keep the plug in a sterile state, and a sterile product that can be stored for a long time. Has been found to be easily manufactured, and the present invention has been completed.

  Examples of the packaging material supply means include means capable of continuously or intermittently supplying a strip-shaped packaging material wound in a roll shape, and use the packaging material supply means in a conventional filling and packaging machine. Can do. The packaging material forming means is not particularly limited as long as it is a means for forming a strip-like packaging material supplied by the packaging material supply means into a flat cylindrical shape so that it can be longitudinally sealed. By forming the packaging material into a flat cylindrical shape, the plug can be easily mounted by the plug mounting means. By this wrapping material forming means, it is possible to fold it in half so that the longitudinal end portions of the strip-shaped wrapping material are aligned with each other to form a flat cylindrical shape. Further, the vertical sealing means is preferably a means capable of heat-sealing the strip-like packaging material, for example, means provided with a heating means and a pressurizing means. Examples include means using sound waves, high frequencies, and laser light.

  The plug mounting means is not particularly limited as long as the plug can be mounted on the outer surface of the flat cylindrical packaging material. The plug mounting is not limited to the flat plug opening. The inside of the cylindrical packaging material is mounted in a state of no communication. Although it does not restrict | limit especially as a mounting method, It is preferable to mount | wear with heat sealing similarly to the vertical sealing means. Examples of the plug mounting means include (1) a plug holding and pressing means for holding the plug and pressing the plug against the outer surface of the flat cylindrical packaging material, and holding the plug with the flat cylindrical packaging material sandwiched between them. A means having a seal pressure support provided from the outer surface side of the flat cylindrical packaging material provided at a position opposite to the pressing means; and (2) holding a plug and holding the plug on the outer surface of the flat cylindrical packaging material.

By arranging the anvil inside the flat cylindrical packaging material, the flat cylindrical packaging material is not deformed when the plug is pressed against the flat cylindrical packaging material by the plug holding and pressing means. It is possible to attach a good mouth plug to the. Further, as described above, the plug mounting means has a seal pressure receiving member provided at a position facing the plug holding and pressing means across the anvil to support the anvil from the outer surface side of the flat cylindrical packaging material. preferable. Thereby, when the plug is pressed against the flat cylindrical packaging material by the plug holding and pressing means, the pressing force of the plug holding and pressing means can be received more reliably, and the desired pressure between the flat cylindrical packaging material and the plug can be obtained. The seal pressure can be generated more reliably. In addition, the filling and packaging machine of the present invention has a half-cut (cut) at the cap attachment position on the surface of the band-like packaging material so that it is easy to form a communication state between the cap (opening) and the inside of the container. A surface half-cutting means that can form the surface may be provided. In addition, although mounting | wearing with a plug is normally performed before filling with a liquid content, it can also be performed after filling with a liquid content.

  The filling means is not particularly limited as long as it is a means for filling the flat cylindrical packaging material fitted with the stopper with the liquid content. For example, a filling pipe inserted into the flat cylindrical packaging material is used. The means which have is mentioned. Such a filling pipe is preferably provided with the anvil. In this case, it is not necessary to separately support the anvil, and a simpler structure can be obtained. Further, the anvil is preferably provided at a predetermined interval from the tip of the filling pipe, for example, about 20 to 100 cm, preferably 40 to 60 cm, so that the plug is attached at such a position. Since it can be performed and is not close to the lateral sealing means, the structure of the plug mounting means can be diversified, and the arrangement thereof is facilitated. The horizontal sealing means is not particularly limited as long as it is a means for sealing the flat cylindrical packaging material filled with the liquid content in a direction intersecting the longitudinal axis of the packaging material at an interval equivalent to one container. Instead, the intersecting direction is preferably perpendicular to the longitudinal axis. As a sealing method, a conventionally known high-frequency heat seal or ultrasonic heat seal is preferable.

Further, a sterilization chamber comprising a sterilization chamber surrounding the sterilization means and a molding chamber surrounding the packaging material forming means is provided. Thereby, the aseptic product which can be preserve | saved for a long term can be manufactured. That is, since a packaging container in which the stopper does not contact the liquid contents can be manufactured, it is not always necessary to provide an aseptic chamber around the stopper mounting means, and only around the sterilizing means and the packaging material forming means. Even a partially aseptic chamber that surrounds can produce aseptic products and can make the filling and packaging machine itself compact. In addition, although the vertical sealing means can be provided in the aseptic chamber (molding chamber), the inside of the flat cylindrical packaging material molded by the aseptic chamber and the packaging material molding means, in order to prevent entry of contaminated outside air, Since the positive pressure is always kept higher than the outside, the vertical sealing means is provided outside the molding chamber, the flat cylindrical packaging material before the vertical sealing is carried out to the outside of the molding chamber, and then the vertical sealing is performed. By doing so, the aseptic chamber can be made more compact.

  Examples of the strip-like wrapping material used in the filling and packaging machine of the present invention include, for example, a single-layer or multi-layer synthetic resin film or a paper as a base material so that heat sealing is possible. A laminated packaging material film in which a resin is laminated is preferable, and a barrier layer that blocks oxygen and light may be laminated on the laminated packaging material film as necessary. In addition, the plug has a function of allowing the plug (opening) and the inside of the packaging container to communicate with each other by screwing or pushing the plug just before eating or drinking. For example, there can be mentioned a stopper having a built-in opening blade described in JP-A-10-129709. The material is preferably made of a thermoplastic resin as a whole or only a thermoplastic resin at the sealing portion with the packaging material so that heat sealing is possible as in the case of the packaging material.
