Oral thermometer

An elongated body of molded plastics material has an end portion with longitudinally spaced and laterally extending temperature numbers overlying corresponding bands of liquid crystal compositions, and an elongated lens of transparent plastics material covers the numbers and compositions and is sealed to the end portion of the body around the compositions. In one embodiment, the compositions are carried by an aluminum strip or foil which has a center portion spaced within a cavity and opposite edge portions projecting to the outer surface of the body between the lens and the body end portion. In another embodiment, the body end portion has longitudinaly spaced cells or cavities for receiving the liquid crystal compositions in a slurry form, and in a further embodiment, the body is molded of a transparent plastics material and has an end portion which forms a second lens to provide a double-sided thermometer. Another embodiment has superposed or overlaid liquid crystal compositions which respond to different temperatures and form segments of digital temperature numbers.
