  • Patent number: 6857199
    Abstract: A drying mold 1 for a pulp molded article has a first mold member 10, a second mold member 20, and a third mold member 30. The first mold member 10 has a drying portion 12 and first passageways 13a and 13b connecting the drying portion 12 to an exterior surface of the first mold member 10. The second mold member 20 has a prescribed heating means and is disposed in contact with the exterior surface of the third mold member 30. The third mold member 30 is disposed in contact with the exterior surface of the first mold member 10. The drying mold 1 is designed to form second passageways 2a and 2b between the first and the third mold members when the first and the third mold members are disposed in contact with each other. The passageways 2a and 2b connect the first passageways 13a and 13b to the outside of the drying mold 1.
