Abstract: The present invention relates to an airtight container lid used for an airtight container to seal a container body by a foldable locking element, and more particularly, a sealing packing is easily detached without being damaged while the sealing packing is installed in the lid, thereby solving an unhygienic problem generated in a region in which the packing is installed. That is, the packing can be easily detached, and it is possible to seal and hygienically clean the region in which the packing of the lid is installed. To this end, a lid is divided into an upper surface, which covers a container body, and a rim having a locking element, the upper surface is detachably coupled to the rim, and an installation groove is formed to closely couple a packing when the upper surface and the rim are coupled and the installation groove is removed when the upper surface and the rim are separated so that the packing is easily attached and separated and the installation groove is easily cleaned.
