The outer surface of the box when the opening is covered by the lid body, which is connected to the end edge of the lid body opposite to the side connected to the box. The cut portion is attached to the surface of the lid-side overlapping portion that is overlapped with the outer surface of the box body, and is provided at a position inside the outer edge of the lid-side overlapping portion. Further, the cut portion extends along the axis of the winding core of the wrap film housed in the box body, and the cutting edge faces the side opposite to the side connected to the lid main body portion in the lid side overlapping portion. It has a blade that is connected to the end of the blade on the side opposite to the cutting edge, and has a blade mounting portion that is attached to the surface of the overlapping portion on the lid side that is overlapped with the outer surface of the box body. The overlapping portion has a bent portion that bends the lid-side overlapping portion so that the surfaces of the lid-side overlapping portion on the opposite side of the outer surface of the box body overlap each other, and the bending portion is the cutting edge of the blade and the blade. At a position between the mounting portion, it extends along the axis of the core of the wrap film housed in the box.

In this wrap film box, the lid-side overlapping portion is bent at the bent portion, so that the blade of the cutting portion protrudes from the outer edge of the bent lid-side overlapping portion. As a result, the wrap film box can cut the wrap film by the blade of the protruding cutting portion. Then, in the state where the bending of the bent portion is extended, the outer surface side of the cut portion is covered by the overlapping portion on the lid side. Here, since the cut portion is provided at a position inside the outer edge of the lid-side overlapping portion, the cut portion does not protrude from the outer edge of the lid-side overlapping portion in a state where the bending of the bent portion is extended. In this way, the wrap film box can cover the cut portion with the lid-side overlapping portion by extending the bending of the bent portion.

In the wrap film box, the portion of the box body on which the lid-side overlapping portion is overlapped is connected to the lid main body portion of the lid-side overlapping portion of the lid-side overlapping portion in a state where the bending at the bending portion is extended. A first slit into which a portion on the side opposite to the side can be inserted may be provided. In this case, the lid-side overlapping portion is inserted into the first slit to prevent the lid-side overlapping portion from bending at the bent portion. As a result, the wrap film box can maintain a state in which the cut portion is covered with the lid-side overlapping portion. Further, by inserting the lid side overlapping portion into the first slit, the lid body is prevented from opening with respect to the box body. As a result, the wrap film box can prevent the wrap film contained in the box from popping out.

In the wrap film box, the lid-side overlapping portion has an insertion portion provided on the side opposite to the side connected to the lid main body portion rather than the bent portion, and the portion where the lid-side overlapping portion in the box body is overlapped. May be provided with a second slit into which the insertion portion can be inserted. In this case, by inserting the insertion portion into the second slit, it is possible to prevent the lid-side overlapping portion from bending at the bent portion. As a result, the wrap film box can maintain a state in which the cut portion is covered with the lid-side overlapping portion. Further, by inserting the insertion portion into the second slit, the lid body is prevented from opening with respect to the box body. As a result, the wrap film box can prevent the wrap film contained in the box from popping out.

Another aspect of the present invention is a wrap film accommodating body, which includes a winding core, a wrap film wound around the winding core, and the above-mentioned wrap film box for accommodating the winding core and the wrap film.

According to this wrap film accommodating body, since the above-mentioned wrap film box is provided, the cut portion can be covered by the lid-side overlapping portion by extending the bending at the bending portion.

According to various aspects of the invention, the cut can be covered.
