  There is a case where a wire material wound in a tubular shape, for example, a wire material for soldering is housed in a packaging box and conveyed. The wire wound in a tubular shape has the outer periphery and the end covered with a packaging film. The inner peripheral portion of the wire is not covered with the wrapping film. Therefore, the wire may be biased toward the inner peripheral side during transportation.

  When the wire rod is mounted on the wire feeder at the destination while being biased, the wire rod may be cut while being fed by the wire feeder. Since the liquid is sealed inside depending on the wire, the liquid leaks due to cutting.

  The present invention has been made in view of such circumstances, and an object of the present invention is to provide a wire rod holder and a packaging box that can prevent positional displacement of the wire rod.

  In the present invention, since the other core material is inserted into the notch provided in the one core material, the two core materials are integrated, the core material is inserted into the entire cavity of the wire material, and the positional deviation of the wire material occurs. Certainly prevented.

  In the wire rod holder according to the present invention, the cover and the core member are configured by a foldable flat member having two parallel slits, and a portion between the two slits in the flat member is the slit. The core material is formed by projecting the fold lines orthogonal to each other at the top or the valley bottom, and the cover is formed by the non-projecting portion of the plane member, and the cover and the core material are the plane member. It is characterized in that it can be deployed as follows.

  In the present invention, since the core member and the cover are formed by providing the flat member with slits and folding the slit, the wire rod holder is detached from the wire rod, then expanded into a flat shape, and then returned to the flat member, and the wire rod holder It is possible to reduce the occupied space.

  The packaging box according to the present invention is characterized by accommodating any one of the above-described wire rod holders holding the wire rod.

  In the present invention, it is possible to prevent displacement of the wire rod housed in the packaging box.
