Method of forming a thermometer structure
Abstract
Abstract A method of forming a thermometer structure, such as a low cost clinical thermometer, wherein the thermometer enclosure structure is formed of plastic as by molding. The capillary element of the thermometer is molded about a taut wire and is removed from the molding cavity by being urged with the wire to an exterior position. The thusly removed element is utilized as a pressure-applying means on the wire to hold the wire taut for subsequent molding of a subsequent element in the mold cavity. A previously formed element is removed from the end of the wire as an incident of drawing the wire through a subsequently formed element. A scale is located on the capillary element by accurately determining the top of the liquid column at a preselected temperature and coordinating the placement of the scale on the element relative to said determined level. One end of the capillary bore is closed by a heat sealing process wherein a projecting portion of the element is deformed to seal the bore end.
