Abstract
Abstract A container comprising an inner container, inner lid, outer container and outer lid which is suitable for commercial transport and legible display of required label information, and can be readily grasped and handled such that the lid and contents can be safely and completely removed. The invention further relates to a plurality of such containers, each container having a different maximum capacity but a label area of at least the same size as the label area of the smallest container and the same distance from the bottom of the container such that application of the labels to the containers can be performed by automated means. These containers are useful, in particular, for storing and transporting hazardous materials such as thick film paste materials.
