Abstract: A food item receiving container. A case defines a receiving space. A lid functions to close the case. Locking wings are integrally formed at edges of the lid, so that they can be pivoted upward and downward. Flange portions are formed on upper end outer surfaces of sidewalls of the case, so that the locking wings are engaged with the flange portions to be maintained in a locked state. An engaging groove is defined on a lower surface of each flange portion. Each locking wing has an elastic engaging part which is formed to be flexed and cover the lower surface of the flange portion when the corresponding locking wing is pivoted downward, and engaging protuberances which are horizontally formed on an upper surface of the elastic engaging part to be engaged with the engaging groove of the flange portion while elastically deforming the elastic engaging part.

Abstract: A plastic, rectangular, airtight container for accommodating food items which comprising a rectangular by shaped container main body having four sides, a plurality locking projections provided on each of the four sides of the container main body, a lid provided with locking wings which are hinged along the periphery of the lid, each said locking wing provided with locking holes which accommodate the locking projections, and each said locking wing provided with a flow intercepting hole disposed between the locking holes for forming channels therebetween so that the plastic molten liquid is induced to flow through said channels by bypassing the molten liquid flow intercepting hole.
