ABSTRACT:
A disposable thermometer is provided with an elongated, transparent housing in a first portion of which is formed a plurality of cavities for receiving temperature indicating means that melt at different temperatures when an elongated, thermally conductive carrier is placed in an orifice of the user's body. The temperature indicating means are initially contained in a solid state within openings in the carrier and are discharged therefrom into the cavities by an elastomeric member that is compressed by the sliding action of a cooperating member. In one embodiment of the invention the openings in the carrier are conical. In an alternative embodiment of the invention the openings in the carrier are cylindrical and a deformable member having a plurality of slots therein that register with the openings in the carrier is secured to the carrier so that when the temperature indicating means are forced outwardly by the elastomeric means the slots in the deformable member will open in order to permit passage of the temperature indicating means to the cavities.
