Abstract
A packing box formed of corrugated paper having a corrugated medium with ridges and grooves arrayed in an array direction, including a first side part, a second side part opposed to the first side part, an inner lid part bent along a first edge portion of the first side part, an outer lid part bent along a second edge portion of the second side part, and an adhesion part for bonding an outer surface of the inner lid part and an inner surface of the outer lid part. The inner surface of the outer lid part is provided with the adhesion part and a score part along the adhesion part. The score part is provided between an edge opposite to the second edge portion and the adhesion part. The score part has a score that does not reach an outer surface of the outer lid part.
Claims14
A packing box formed of corrugated paper having a corrugated medium with a plurality of ridges and grooves arrayed in an array direction,
- the packing box comprising:
- a first side part extending in a first direction and a second direction intersecting the first direction, the first side part having a first edge portion at an edge in the first direction of the first side part and extending in the second direction;
- a second side part being opposed to the first side part and extending in the first direction and the second direction, the second side part having a second edge portion being on the same side as the first edge portion in the first direction and extending in the second direction;
- an opening surrounded by the first edge portion of the first side part and the second edge portion of the second side part;
- an inner lid part provided to be bent along a first bending line so as to close at least a part of the opening and extending in the second direction and a third direction intersecting the first direction and the second direction, the first bending line extending in the second direction at the first edge portion of the first side part;
- an outer lid part provided to be bent along a second bending line and extending in the second direction and the third direction, an inner surface of the outer lid part overlapping at least a part of an outer surface of the inner lid part from outside, the second bending line extending in the second direction at the second edge portion of the second side part;
- and
- an adhesion part for bonding the inner surface of the outer lid part and the outer surface of the inner lid part, wherein
- the outer lid part is configured such that the array direction of the ridges and grooves of the corrugated medium is the third direction, and
- the inner surface of the outer lid part is provided with a score part between an edge opposite to the second bending line in the third direction and the adhesion part, the score part has a score provided along the second direction, and the score does not reach an outer surface opposite to the inner surface of the outer lid part.
