That is, in terms of manufacturing, in order to manufacture a bag-shaped container with a spout which is an inner container of this container, the edge portions of a single-layer or multi-layer film are pasted together by a means such as heat sealing to form a bag, and There is a problem that the spouts formed by injection molding or the like must be joined by means such as welding, and the number of manufacturing steps is large. In terms of performance, the heat-sealed portion at the edge of the film and the welded portion at the spout are generally inferior in impact resistance to the film portion, and there is a problem that the bag may be broken by a drop impact.

ある。An important feature of the composite container according to the present invention is that the thickness of the outer container mainly made of paper is 2.5 times or more, preferably, the average thickness of the body portion of the plastic inner container manufactured by blow molding. It is 2.5 to 5 times. That is, when the thickness of the outer container is 2.5 times or less the thickness of the inner container, for example, when the inner container is too thick, the rigidity of the inner container is large and it is difficult to reduce the volume at the time of disposal. The thickness of the container is 5 that of the inner container.
If it exceeds double, that is, if the outer container is too thin, sufficient mechanical strength of the container cannot be obtained. This is based on the findings obtained from the experimental results of the present inventors.

を含んでいても良い。The inner container made of plastic is manufactured by blow molding, but it is preferable to manufacture it by stretch blow molding because it is oriented in the molecular stretching direction and the mechanical strength of the container is improved. Further, as a material suitable for stretch blow molding, polyethylene terephthalate resin, polypropylene resin, high nitrile resin, polystyrene resin, polyvinyl chloride resin, polycarbonate resin or the like can be used, but polypropylene resin has good stretch blow moldability. It is particularly desirable because it has excellent water vapor barrier properties and good hygiene. The polypropylene resin used is

It is desirable to have a multi-layered structure containing at least one excellent material. As the gas barrier material, polyamide resin, ethylene-vinyl acetate copolymer saponified resin, high nitrile resin and the like can be used. Similarly, in the case of a content that does not like the emission and absorption of water vapor, a material having an excellent water vapor barrier property can be used. As a material having excellent water vapor barrier properties, an amorphous resin obtained by copolymerizing a cyclic olefin and ethylene can be used.

Therefore, the volume can be reduced at the time of disposal (for example, folding,
It also has the function of being able to reduce the volume by crushing etc.), so it also solves the dust problem in the disposal process and has a good impact on the environment.
