Abstract

A package packages an object to be packaged by placing the object to be packaged on a tray box, covering the object with packaging corrugated cardboard from the top, and wrapping a binding band. The packaging corrugated cardboard includes a peripheral wall having a pair of first sidewalls and a pair of second sidewalls, an inner flap connected to a top side of each of the first sidewalls, and an outer flap connected to a top side of each of the second sidewalls. Each inner flap is provided with a pair of protrusions protruding from both side ends of the flap. When the inner flap and then the outer flap are closed, an opening on a top side of the peripheral wall is closed with the protrusions being brought into contact with the second sidewalls.

Claims

1. A package comprising:

a peripheral wall to have a pair of first sidewalls facing each other, a pair of second sidewalls facing each other, and an opening at one end;

an inner flap to be provided at the one end of each of the first sidewalls;

a pair of protrusions to protrude from both side ends of the inner flap; and

an outer flap to be provided at the one end of each of the second sidewalls and be provided with a notch, the size of which is larger than or equal to the size of each of the protrusions, at a position corresponding to each of the protrusions, wherein

closing of the inner flap and then the outer flap closes the opening at the one end of the peripheral wall with the protrusions being brought into contact with the second sidewalls.

2. The package according to claim 1, wherein

an edge of each of the protrusions is brought into contact with the second sidewall when the inner flap and the outer flap are closed.

3. The package according to claim 1, wherein

each of the protrusions is bent at some midpoint to cause a surface on an edge side of the protrusion being bent to be brought into contact with the second sidewall when the inner flap and the outer flap are closed.

4. The package according to claim 3, wherein

each of the protrusions is bent with an edge facing downward.

5. The package according to claim 1, wherein

each of the protrusions is folded back at some midpoint to cause a part being folded back to be brought into contact with the second sidewall when the inner flap and the outer flap are closed.

6. The package according to claim 1, wherein

each of the protrusions is provided at a position that is the same distance away from an edge of the inner flap.

7. The package according to claim 1, wherein

the package is formed by using corrugated cardboard.
