ABSTRACT:
A poultry or meat cooking timer has a hollow barrel with an open top slidably receiving a stem with an inner end immersed in a fusible holding material in the barrel to normally hold the stem within the barrel against the force of a spring in the barrel urging the stem outwardly therefrom. The stem has an integral tapered flange thereabout that is force fitted through an inner barrel ridge near the top of the barrel bore and the stem has a large top with a substantially flat surface for engaging a barrel flange for positively sealing the stem and barrel in normal retracted stem position to prevent intrusion of foreign substances into the barrel bore prior to stem release by the fusible material at a predetermined temperature.
