    摘要： An object of the invention is to provide a technique in which a decrease in physical properties is suppressed or consumer complaints are diminished.
    A method for filling a particulate water absorbing agent includes a filling step of filling a particulate water absorbing agent into a filling container and a vibrating step of vibrating the filling container at the outside of the filling container, the vibrating step being conducted at least one time between the start and the end of the filling step, in which a vibration condition in the vibrating step satisfies the following conditions (a) and (b):
    (a) vibration by a vibrating body in contact with the filling container has a vertical directional component and a vibrational angle is within 90° ± 30°; and
    (b) total amplitude at no load and a vibration frequency at no load of the vibrating body are set so as to satisfy Equation 1-1 and Equation 2 or Equation 1-2 and Equation 2.

    摘要： The present invention relates to a method for continuous production of a water-absorbent resin by use of an continuous polymerization device having a charge part of a monomer aqueous solution; an endless belt on which the monomer and a hydropolymer formed are conveyed; and a discharge part of the hydropolymer, wherein the continuous polymerization device has side walls and a ceiling, and the space ratio in the device represented by the equation, "space ratio in the device=B/A", is in the range of 1.2 to 20. In the equation, A is a maximum cross-sectional area (cm 2 ) of the hydropolymer during the polymerization in the width direction of the endless belt, and B is a maximum cross-sectional area (cm 2 ) of the space between the endless belt of the continuous polymerization device and the ceiling of the continuous polymerization device in the width direction of the endless belt.
