Abstract: There is provided a trocar button having an enlarged flat head at the larger exterior end connecting with a conical body and a pointed bulbous end. The large part of the conical body connects with the enlarged flat head. Between the small part of the conical body and the pointed bulbous end there is a neck. In the body of the trocar button including the enlarged flat head, the conical body, the neck, and part of the pointed bulbous end, there is a cavity. With the removal of the pointed bulbous end at the neck, there is created a through passageway in the trocar button. A needle attached to a syringe, can be inserted in the through passageway and into the interior of the cadaver. Then, an embalming fluid can be forced through the needle and into the interior of the cadaver. Also, the through passageway allows gas in the cadaver to escape. Further, if there be a liquid in the cadaver some of that liquid can collect in the passageway. On the exterior of the conical body there is a thread.

Abstract: This invention is directed to a frenum lock, also know as a natural expression former, for use by morticians. The improvement of this invention is the increased thickness of the central area or the medial area of the frenum lock and the decreased thickness of the peripheral areas, i.e., spaced end or wing area, of the frenum lock. As a result, there is more rigidity in the medial area of the subject frenum lock and more flexibility in the peripheral areas or wing ends of the frenum lock. This makes it easier for the mortician to insert and to position the frenum lock between the lips and the gums of the cadaver for the cadaver to have a natural appearance.

Abstract: This invention is directed to a frenum lock, also known as a natural expression former, for use by morticians. It relates to an improvement on two of my patents. I have a patent entitled "NATURAL EXPRESSION FORMER", U.S. Pat. No. 3,103,052, issuing date of Sept. 10, 1963 and a patent entitled "NATURAL EXPRESSION FORMER WITH BITE INDENTATION", U.S. Pat. No. 3,195,215, issuing date of July 20, 1965. The improvement of this invention is the positioning of the dividing lines in the central portion of the natural expression former or the frenum lock. The dividing lines in the central portion of the frenum lock permit wider spreading of the expression forming wing-like portions on insertion of the expression former into the mouth of the corpse or cadaver and permit greater adaptation of the expression former to the dental arch of the corpse or the cadaver.
