は困難であった。<< Conventional technology >> Conventionally, as individual packaging of milk, concentrated coffee, etc.
As shown in FIG. 7 and FIG. 7, an individual package is used in which a container made of polystyrene, polypropylene, or the like is filled with the contents and then heat-sealed with a lid material mainly made of aluminum foil, as shown in FIG. When the lid material is peeled off from the container at the time of opening, there is a drawback that the contents are vibrated, and particularly when the container is pressed with a finger, the inside of the container is pressurized and scattered, thereby soiling clothes and hands. Further, a container made of polypropylene or the like has been adopted as a container for heating and storing the prepared foods and the like, but it has been difficult to heat under pressure.
《発明が解決しようとする課題》 本発明は、これらの欠点を解決したものであり、開封

ことを特徴とする個包装体の製造方法である。<< Means for Solving the Problems >> The present invention relates to an individual packaging body comprising a polypropylene container and a lid member having a portion which can be deformed into irregularities through a rib portion having a hinge effect along the periphery of the bottom portion. A state in which the container is filled with the liquid food in a state where the deformable portion is convex and the container is hermetically sealed with a lid material, and then the deformable portion is concave and the inside of the container is pressurized. It is a manufacturing method of the individual package characterized by the above-mentioned.

り、コーティングしたりすることもある。The material of the container (6) used here must be a polypropylene resin having a hinge effect, but if barrier properties are required, a saponified product of vinylidene chloride and ethylene-vinyl acetate copolymer is used. May be laminated or coated.
《作用》 容器の底部の変形可能な部分は最初凸状になったまま
で充填され密封される。その後変形可能な部分が凹状に
されるため、容器の内部の容積が縮小される。従って密
閉された状態では容器の内部は容積の縮小分だけ加圧さ
れた状態になる。内容物が常温充填の場合は容積の減少
した分だけ加圧される、又内容物がホット充填の場合は
冷却されると減圧され、減圧された分と容積の減少によ
る加圧された分との差で容器の内部は大気圧より高いか
低いかの状態となる。容器の内部の圧力の調整は、変形
可能な部分の大きさ又は内容物の充填量を適宜変えるこ
とによって行うことができる。<< Operation >> The deformable portion at the bottom of the container is filled and sealed while keeping its convex shape at first. Thereafter, the deformable portion is made concave, so that the volume inside the container is reduced. Therefore, in the closed state, the inside of the container is pressurized by the reduced volume. When the contents are filled at room temperature, the pressure is increased by the reduced volume, and when the contents are hot-filled, the pressure is reduced when the contents are cooled. The inside of the container becomes higher or lower than the atmospheric pressure due to the difference. The pressure inside the container can be adjusted by appropriately changing the size of the deformable portion or the filling amount of the contents.
本発明の個包装体の製造方法は、容器の内部が加圧さ
れた状態になっているので、特にシート状のフタ材は皺
がなく張り詰めた状態となり外観が非常に良好になり、
又容器の底部は変形可能な部分が凹状になっているた
め、底部の出張りがないので、安定した状態で置くこと
ができる。In the method for producing an individual package of the present invention, since the inside of the container is in a pressurized state, the sheet-shaped lid material is in a tightly packed state without wrinkles, and the appearance is very good,
In addition, since the deformable portion of the container has a concave portion at the bottom, there is no protrusion at the bottom, so that the container can be placed in a stable state.
更に本発明では、内容物がホット充填の場合は使用時
にフタ材を指で押圧して変形可能な部分を凸状に変形さ
せると、容器内がより減圧されるのでフタ材を開封した
時にも内容物が飛散することがない。Furthermore, in the present invention, when the contents are hot-filled, pressing the lid material with a finger at the time of use to deform the deformable portion into a convex shape when the lid material is opened because the pressure inside the container is further reduced. The contents do not scatter.
更に又本発明で、内容物が常温充填の場合は容器内が
加圧されているので、加圧殺菌や加圧調理を行っても容
器が変形することがない。Furthermore, according to the present invention, when the contents are filled at room temperature, the inside of the container is pressurized, so that the container is not deformed even if pressure sterilization or pressure cooking is performed.
