A shipping container for liquids is described. This consists of an outer corrugated paperboard container containing an inner corrugated liner forming corner posts. A flexible or semi-flexible bladder or jug generally conforming in cross section to the inside of the corrugated container contains the liquid. It is desirable for the in- ner corrugated liner to be bonded to the outer container, especially along the margins of the corner posts. It has been found to be critical that the ratio of the length of the outside face of the outer container to the corner post length should be no greater than about 8:1. This is essential to prevent face bulging, especially when the inner plastic container is filled with a high density material such as a paint. Where the inner plastic container has an upstanding handle or spout it is useful to have filler pieces that bear between the plastic container and upper flaps of the outer corrugated container. This prevents any up and down motion of the inner container during normal handling or under the severe stresses that might be imposed on a paint shaker.
