ABSTRACT:
Blow molded, tight head plastic containers are provided with interlocking means in the form of a groove on the top section of the container, a tongue on the bottom section of the container and a peripheral rim about the top section of the container. When similar containers are stacked upon one another, this construction permits the stack to remain vertically aligned even when it is tilted to angles of 45.degree. to the vertical.
