Abstract:
1. A temperature sensitive indicator, comprising: a member base including an upper base member and a lower base member; and a label component, one end of which is sandwiched and held between the upper base member and the lower base member of the member base and another end of the label component is protruded outward, the label component comprising: a sheet member; an absorbent member provide on an upper part of the sheet member; a capsule placed on one end side of the absorbent member and containing a temperature sensitive material that melts at a predetermined temperature or more which is the temperature at which the temperature sensitive material melts into a liquid; and a cover member including a protrusion covering the capsule, wherein the protrusion of the cover member is held inside the member base, housed in a convex portion provided on any one of or both of the upper base member and the lower base member, and wherein, by pulling the another end of the label component out of the member base, the capsule is pressed in the convex portion of the lower base member and is broken to enter a preparatory state for measurement, and the temperature sensitive material melts into a liquid at the predetermined temperature or more so that the liquid is absorbed by the absorbent member and turns color, thereby coloring the absorbent member and enabling confirmation that the temperature sensitive indicator senses a temperature equal to or greater than the predetermined temperature through confirmation of the coloring of the absorbent member by the liquid, the upper base member and the lower base member each comprising a bent portion provided between the convex portion of the member base and a side end portion of the member base from which the pulled-out portion of the label component protrudes.
