An incrementally variable volume container includes a sectionalised side wall and a closed bottom end. Each section has a top rim with an external thread for engaging a threaded lid. A tear strip is integrally molded between each top rim and a next section of the container to permit the next section to be removed. The container is used to contain perishable liquid, semi-solid or granular food items. The sections can be detached and discarded as the food content is consumed, and the lid can be used to close any section in fluid tight seal. Air volume in the container above the food content is thereby reduced and the freshness of the food content is maintained.
