Description

  The present invention relates to a packaging box for housing a film or the like wound in a roll shape, and a boxed roll accommodated in the packaging box.

  Many thin sheet-like members such as paper and film are rolled and accommodated in a cardboard box or the like for transportation and storage. Conventionally, when packing a roll-shaped object (hereinafter sometimes simply referred to as “roll”) in a cardboard box or the like, for the purpose of protecting the cross section of the roll, A method has been adopted in which a pad made of paper or metal is laid and the pad and roll are fixed with a washer. When the rolls are packed in this way, the pads and washers are no longer necessary after unpacking, so they are discarded as garbage.

However, recently, due to increasing interest in environmental issues, it has been desired to reduce the amount of waste, and it has become a problem to dispose of the above-mentioned pads and washers. As a technique that can solve such a problem, for example, Patent Document 1 discloses a square-shaped main body having an opening plane square shape, and both ends of the main body having a locking piece whose width is substantially equal to the inner diameter of the object to be accommodated. Oppositely provided outer flaps, opposite to both ends of the main body having fitting pieces having slits that form fitting grooves into which the engaging pieces are fitted, the width being substantially equal to the inner diameter of the object to be accommodated The technology regarding the packaging box which is comprised by the inner flap provided by this and forms the holding | maintenance part of a to-be-contained object by assembling each latching piece and a fitting piece at the time of packing is disclosed.
