A seamless capsule comprising a content and a film for coating said content is disclosed. The content is a hydrophilic substance. A viscous liquid having a viscosity of not more than 1000 cp at 100.degree. C. which is scarcely miscible with water is present between the content and the film. There is also disclosed a process for producing a seamless capsule which comprises simultaneously extruding a film solution for the seamless capsule, a hydrophilic substance solution and a viscous liquid which is scarcely miscible with water into a cooling solution from a concentrically arranged multiple nozzle composed of at least three nozzles, an outermost nozzle, an innermost nozzle and at least one intermediate nozzle placed in the middle position between the above nozzles, respectively, the diameter of said nozzle gradually increasing in that order.

Seamless capsule and process for producing the same

There is provided a disposable temperature indicator utilizing a change in condition of organic compounds at their melting point for the indication of temperature. The disposable temperature indicator is used as a disposable clinical thermometer which comprises a temperature-sensing portion having a temperature-indicating mixture composed of a solid solution of two organic compounds belonging to n-aliphatic hydrocarbons, nontoxic, odorless and having a narrow range of melting points particularly suitable for use in clinical thermometers or a temperature-indicating mixture containing an amount of color reagent as means for developing a change in color upon the change from the solid to liquid state of the temperature indicating mixture upon exposure to heat of a body to be temperature-registered; and a temperature-indicating portion formed of a porous thin plate with one surface or both surfaces thereof coated with one or both of a pair of compounds soluble in said temperature-indicating mixture, such resulting coating serving to produce a color compound by reaction with said temperature-indicating mixture.
