Description

  The present invention relates to a composite container composed of a flexible packaging bag and an exterior member, and more particularly to a composite container provided with self-supporting properties.

Conventionally, flexible packaging bags can be stored and transported in a lying state and are used as containers for packaging many products including foods and confectionery because of their low cost. . In addition, a square bottom bag, a standing pouch, etc., in which the flexible packaging bag is made self-supporting, have been used for various contents. Further, composite containers made of soft packaging bags and paperboard cartons or cardboard boxes include bag-in-cartons, bag-in-boxes, etc., which have been put into practical use by skillfully combining the characteristics of both materials. These naturally have a self-supporting property (see, for example, Patent Document 1).
