Temperature indicating compositions are provided for use in disposable thermometers comprising a heat-conductive carrier sheet having at least one but preferably a plurality of regions (cavities) thereon, each region containing a thermally responsive substance which undergoes a change in state at a precise and predetermined temperature different from any other region. The thermally responsive materials used herein as temperature indicating compositions are solid solutions comprised of two components which, inter alia, have linear temperature-composition liquidous curves. The change of state of the solid solution in each region is readily detectable visually by an indicator system which is intimately associated with the solid solution in said regions in order to permit rapid and accurate visual determination of the temperature of the test subject.

Temperature indicating compositions

A package for the complete and protective enclosure of an article is described in which the article is fully enclosed by a continuous surface of rigid or semi-rigid material so as to form a housing. The housing is banded by a section of sufficiently reduced wall thickness to permit the frangible separation of the housing into two segments which are then drawn apart with the enclosed article being engaged by one of the segments for withdrawal from the other segment. The article can be fully assembled or partially assembled while in the package and means are described in the latter instance for dispensing the fully assembled article automatically in the course of removing it from the package.
