Title: Mat for holding medicine vaporizable by heating
Inventor: FUKUSHIMA KIYOSHI
IPC: A01M1/20
Filed: 1979-02-16
Abstract: PURPOSE: Title mat for insecticide that is composed of a porous base holding an insecticide formulation vaporizable by heating and a metal thin film formed on the surface of the base to be heated, thus increasing the vaporization rate of the formulation and reducing the decomposition because of its uniform heating and good heat transmission in the widthwise direction.
