Abstract:
1. A heat and steam generator for eye application comprising: a holder holding a heat and steam generating member containing an oxidizable metal which generates heat and steam by making use of an oxidative reaction of the oxidizable metal, the heat and steam generator being designed to supply steam to eyes and its surroundings, wherein the heat and steam generator releases steam from its side adapted to face the eyes and its surroundings for a period of 1 to 30 minutes to maintain the surface temperature of the skin which it faces at 34° C. to 43° C. over a period of 1 to 120 minutes, wherein the holder and the heat and steam generating member form a structure having a stiffness of 0.01 to 10 N/7cm-width, as measured by supporting a portion of the holder, which holds the heat and steam generating member, at opposing ends of the portion of the holder which extend in a vertical direction of the holder, and measuring a maximum resistance encountered by a platy penetrator blade which contacts a central the portion of the holder, and wherein a span of a specimen of the holder used for measuring the stiffness is 80 mm, the platy penetrator blade has a width of 50 mm and a tip radius of 5 mm, a crosshead speed of the platy penetrator blade is 20 mm/min, and, for measuring, the width of the platy penetrator blade coincides with the vertical direction of the holder.
