| Abstract: |
A temperature indicator which in one preferred embodiment comprises a translucent or transparent confectionery head having a cavity therein. A flexible elongated resilient stem, preferably formed of a plastic material has one end thereof, which is provided with a plurality of small holes, inserted into the cavity. Each of the holes is at least partially filled with a temperature sensitive material capable of melting at a temperature typically within the range from 96 DEG to 110 DEG F With each material mounted within a hole being adapted to melt at a different temperature within the aforesaid range. The material filling each hole within the stem is preferably of a color which contrasts with the material in the other holes for ease of identification. One or more of the materials in each hole will melt depending upon the temperature of the individual ingesting the lollipop. Each temperature sensitive material is completely non-toxic and may be ingested together with the confectionery head without any danger of harming the user. The confectionery member may also take the form of a pacifier.

What is claimed is:
1. A temperature sensitive device especially adaptable for use in taking a child's temperature comprising:
- a confectionery body having a cavity extending to at least one end thereof;
- an elongated flexible resilient stem having a first end thereof inserted into said cavity;
- said first end having at least one opening provided completely therethrough which is substantially completely enclosed by said confectionery member when the first end of the stem is positioned in the confectionery head; said opening being in the shape which would be formed by a plane geometrical figure passing through said stem;
- a temperature sensitive element at least partially filling said opening in said stem;
- said confectionery head having at least a portion thereof which is substantally transparent so as to facilitate observation of the temperature sensitive element in said opening from either direction transverse to the plane of said opening;
- said temperature sensitive element being of a contrasting color relative to the substantially transparent portion of the confectionery member through which it is viewed;
- said element adapted to be substantially completely melted at a predetermined temperature level so as to substantially completely flow out of said opening and thereby effectively disappear from said stem to provide a positive indication of the predetermined temperature level.
