Abstract

PURPOSE:To provide a dust prevention synthetic resin hollow body by setting a synthetic resin hollow body in the die, inserting a cathod rod into the hollow body, applying some voltages with an anode of die and charging the outer circumferential surface of the hollow body to a negative value. CONSTITUTION:The inner wall surface of the die 1 is covered by the conductor 11 electrically insulated and the conductor 11 is connected to a power supply of the anode. Synthetic resin hollow body B is set in the die 1, the outer circumferential surface of the hollow body B is closely contacted with the inner wall surface of the die under an application of the inner pressure, and an anode voltage is applied preferably more than 600V/cm<2> to the conductor 11 covering the inner wall surface of the die with the expansion rod 3 being a cathod. Then the dividing voltage is caused in the hollow body B and the inner circumferential surface is positively changed, the outer circumferential surface closely contacted with the inner wall surface of the die is negatively changed similar to a negative value of the floating dust as well as the inner circumferential surface is positively charged, so that when the content is charged or loaded and displayed in a front of a storage section, the dust may be prevented from being adhered to improve more a validity of the product.
