An applicator [1] is provided for dispensing a predetermined quantity of semiliquid preparation into a body cavity especially the vagina, but also possibly the rectum, mouth, nose and ear. The applicator comprises a barrel [2] having an open delivery end [3] and an opposite operating end [4], and a plunger [5] movable along the length of the barrel between a charged position in which it is located towards the operating end of the barrel and a discharged position in which it is located towards the delivery end of the barrel. Biasing means [11] have a loaded condition corresponding to the charged position of the plunger and an unloaded position corresponding to the discharged position of the plunger with the biasing means being operative to move the plunger from its charged position to its discharged position upon release thereof. Manually releasable catch means [12] hold the biasing means in the loaded condition. A safety unit [15, 16] prevents operation of the manually releasable catch means unless the plunger is in its charged position. Preferably, an operating stem is provided for moving the plunger from its charged position to its discharged position and the operating stem and plunger are movable to their loaded and charged positions independently of each other so that the biasing means may be charged whilst the plunger remains in its discharged position.
