After dropping Staphylococcus aureus and E. coli adjusted to a viable cell count of 10 5 CFU / ml on three test pieces, immediately place a 4 cm ⁇ 4 cm film on each test piece from the outside of the dropped Staphylococcus aureus and E. coli. made it adhere. hare. Immediately after and 24 hours after the above step (a), the film was taken and washed with SCDLP medium. workman. The washing liquid obtained in the above c was diluted 10 times, 100 times and 1000 times using the diluent.
  • Phosphate-buffered saline was used as a diluent. E. 1 ml of each liquid obtained in d above was transferred to a petri dish, and an agar medium was poured thereinto to solidify. Here, two petri dishes were prepared for each liquid. power. The culture medium obtained in (e) above was cultured in a constant temperature bath at 35° C. for 48 hours, and the number of colonies was measured to calculate the sterilization rate. (4) Test results Table 1 shows the results of this test.
  • the sterilization rate in Table 1 is the value calculated by dividing (positive control viable count - test sample viable count) by the positive control viable count. As shown in Table 1, at all points 1 to 3, the sterilization rate for both Staphylococcus aureus and Escherichia coli was 92% or more. This confirmed the effectiveness of the antibacterial treatment by the spray device of the present invention.
  • the spraying device of the present invention can be used for spraying various liquids, but it is particularly useful as a spraying device for liquids having a disinfecting action, specifically metal ion aqueous solutions, more specifically silver ion aqueous solutions and copper ion aqueous solutions. It can be used suitably.
