IPC: A61L2/16
Filed: 2003-03-07
Abstract: <P>PROBLEM TO BE SOLVED: To improve the antistatic effect of a dust cup 5b, to completely and easily dispose dust inside and to improve sanitation.  <P>SOLUTION: The dust cup (dust collecting container) 5b is constituted of a resin (polymer alloy type resin) whose surface specific resistance is smaller than 10<SP>10</SP>Ω/cm<SP>2</SP>. To produce the polymer alloy type resin, for instance, an antistatic polymer is alloyed with an ABS resin. When the surface specific resistance of the resin is smaller than 10<SP>10</SP>Ω/cm<SP>2</SP>, electric charges that the dust possesses are immediately absorbed by the resin, and discharged into air and electrostatic attraction of the dust to the inner surface of the dust cup 5b is reliably suppressed. Also, in the resin, an antibacterial agent containing metal ions is contained. The antibacterial agent is contained by ≥0.2% and ≤0.9% (preferably ≥0.2% and ≤0.5%) by a weight ratio to the resin. Thus, bacteria led to the dust cup 5b together with the dust in the air are removed.  <P>COPYRIGHT: (C)2004,JPO&NCIPI
