摘要： A method and apparatus for altering the configuration of a limited portion of a container defining surface of a mold wall after each cycle of a container thermoforming operation, without removing the mold from its place in a machine, so as to prevent successively produced containers from sticking together when stacked or nested.

摘要： A method for altering the configuration of a series of containers produced in a mold such that the containers can be nested together without sticking. A first container is made by differential pressure forming a thermoplastic sheet in a mold having means for forming stacking lugs in the surface of the container. The means forming the stacking lugs are then automatically altered in position so as to present a mold having a different configuration at the surface where the stacking lugs are formed and a second container is formed in the mold. The containers are then nested and the stacking lugs of different configuration prevent sticking together of the containers.
