Abstract
A suppository applicator for inserting suppositories into body cavities comprises a tubular body having an open end and a closed end. A plunger is slidably disposed in the tubular body for reciprocal movement between a withdrawn position and an extended position and a combined spring is situated between the plunger and the closed end of the applicator to urge the plunger toward its extended position. The tubular body is formed with a longitudinal slot along its side which has a notch that extends from the slot to engage a latch on the plunger and hold the plunger in its withdrawn position. The open end of the tubular body is shaped to stationarily hold a suppository against the withdrawn plunger until the suppository is to be inserted into the body cavity. When the latch is released, the spring pushes the plunger against the suppository to insert the suppository into its desired placement in the body cavity.
