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.
Claims6
An improved disposable cooking timer comprising
- a barrel having a hollow interior and adapted to being inserted into an item to be cooked,
- said barrel having a closed inner end and an open outer end with a flange thereabout having an upper surface,
- a stem slidably disposed in said hollow interior of said barrel,
- resilient means urging said stem out of the open end of said barrel, and
- a fusible material having a predetermined melting temperature disposed in the inner end of said barrel in engagement with said stem and barrel for releasably retaining said stem in said barrel against the urging of said resilient means when the item temperature is below said predetermined melting temperature, and
- said stem having an enlarged flat outer end extending radially outward of said stem atop said barrel flange and having an under surface complementary to said upper surface of said barrel flange for mating therewith to seal the interior of said barrel against intrusion by foreign material prior to release of said stem by said fusible material.
An improved disposable timer comprising
- a barrel adapted to being inserted into an item to be cooked,
- barrel having a hollow interior and an external flange about an upper open end of said barrel with a substantially flat upper surface,
- a solid fusible material disposed in said barrel, and
- a spring loaded stem disposed in said barrel and biased outwardly of said upper open end of said barrel said solid fusible material releasably retaining said stem in said barrel, said stem having an enlarged outer end with a substantially flat under surface adapted to mate with said flat upper surface of said barrel flange for positively sealing the interior of said barrel prior to release of said stem by said fusible material to prevent intrusion of foreign substances into said barrel, said fusible material melting at a predetermined temperature and releasing said stem.
