A container structure for sealing and keeping food fresh, which can be repacked after unpacking. The container structure has a container body and a covering film; the container body has a housing chamber, a first abutting face, a concave groove portion, a second abutting face and a preset break line; the covering film can seal the housing chamber and bond with the first and second abutting face, specifically, it is bonded to the first abutting face through the micro sealing portion, so that the bonding between the covering film and the first abutting face is weaker than the bonding between the second abutting face; To open the covering film, the user needs to apply a force upon the external edge of the top end of the container body, to break the preset break line, and to separate the covering film from the first abutting face, so as to form a separated and independent frame.
