Carrying case

A carrying case comprising:

• a first main body having a semi-ellipsoidal shell shape;
• and
• a second main body having a semi-ellipsoidal shell shape corresponding to the first main body so that the second main body is coupled to the first main body to define an ellipsoid, wherein a coupling end of the first main body, which is coupled to the second main body, has two or more pairs of connected convex portions and two or more pairs of connected concave portions, such that a lateral side at a major axis side has a taegeuk shape,
• wherein a coupling end of the second main body has concave portions formed at positions corresponding to the convex portions of the first main body, and convex portions formed at positions corresponding to the concave portions of the first main body, and wherein one or two cut-out grooves having a preset length perpendicular to the coupling end are formed at one coupling end or two opposite coupling ends of the first main body and the second main body,
• wherein coupling members are respectively provided on the first main body and the second main body, and a connection part connected to a mask strap is coupled to the coupling members,
• wherein the connection part comprises:
• couplers coupled to central regions of the first main body and the second main body;
• connection strings respectively coupled to the couplers;
• and connection rings coupled to ends of the connection strings so as to be connected to the mask strap, and
• wherein reel-shaped storage boxes are respectively disposed inside the first main body and the second main body, and the connection strings are semi-automatically wound in the reel-shaped storage boxes.

A carrying case comprising:

• a first main body having a semi-ellipsoidal shell shape;
• and
• a second main body having a semi-ellipsoidal shell shape corresponding to the first main body so that the second main body is coupled to the first main body to define an ellipsoid, wherein a coupling end of the first main body, which is coupled to the second main body, has two or more pairs of connected convex portions and two or more pairs of connected concave portions, such that a lateral side at a major axis side has a taegeuk shape,
• wherein a coupling end of the second main body has concave portions formed at positions corresponding to the convex portions of the first main body, and convex portions formed at positions corresponding to the concave portions of the first main body, and wherein one or two cut-out grooves having a preset length perpendicular to the coupling end are formed at one coupling end or two opposite coupling ends of the first main body and the second main body, and
• wherein one or more guide rods are respectively coupled to inner surfaces of the first and second main bodies so as to be parallel to a major axis of the ellipsoid, and rollers are penetratively coupled to the guide rods, respectively.
