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.

1. A food item receiving container, comprising:a case opened at an upper end thereof to define a receiving space therein;a lid for closing the opened upper end of the case;a plurality of locking wings integrally formed at edges of the lid, respectively, so that they can be pivoted upward and downward; andflange portions projectedly formed in the shape of a band on upper end outer surfaces of side walls of the case, respectively, so that the locking wings can be engaged with the flange portions to be maintained in a locked state;wherein at least one engaging groove is defined on a lower surface and at a middle portion, facing a corresponding locking wing, of each flange portion, andwherein each locking wing has an elastic engaging part which is formed to be flexed and thereby 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. 2. The container as set forth in claim 1, wherein two elongate engaging grooves are parallel defined on the lower surface of the flange portion; and two elongate engaging protuberances are formed on the upper surface of the elastic engaging part of the locking wing to be engaged into the two elongate engaging grooves, respectively. 3. The container as set forth in claim 1, wherein the engaging groove of the flange portion is formed with a first inclined surface which is inclined upward from an outside toward an inside of the flange portion; and the upper surface of the elastic engaging part of the locking wing comprises a second inclined surface which is inclined in an opposite direction to the first inclined surface of the engaging groove so that the second inclined surface is engaged with the first inclined surface while the locking wing is in the locked state.
