PROBLEM TO BE SOLVED: To provide an egg packaging container which does not lower no the sealing strength of the egg packaging container itself, and in addition, enables a quick and light tearing-up operation by a consumer by finger tips of one hand. SOLUTION: Parallel two rows of perforations (11b) and (11a) for opening this container which are inserted between rising base end ridges (12a) and (12b) of egg housing recesses (7a) and (7b) and a heat-sealed section (10) are provided as follows. One first perforation (11b) is formed from the upper side by a first rotary cutter to a longer edge hemming flange (1b) on a lid body (B) side, and the second perforation (11a) which is the remaining other perforation is formed from the lower side by a separate second rotary cutter to a longer edge hemming flange (1a) of a container body (A) side simultaneously all at once. Also, the first and second perforations (11b) and (11a) are formed in a staggered arrangement state that cutouts (11b-y) and (11a-y) of the first and second perforations (11b) and (11a) cross with each other.
