Abstract:

The purpose of the present invention is to further reduce the size and weight of an applicator. An applicator (A1) is provided with a housing (10), a piston plate (20), a micro-needle array (30), a conical coil spring (40), and an unlocking member (50). The housing (10) has a cylindrical body section (12) for housing the piston plate (20) and the conical coil spring (40), and also has a lid section (14) for gripping the conical coil spring (40) between the lid section (14) and the piston plate (20). The body section (12) has inner walls (12b1-12b4) for engaging the piston plate (20) with the housing (10) through protrusions (20c1-20c4). The body section (12) has vertically extending grooves (G1-G4). The piston plate (20) is guided in the axial direction of the body section (12) by the grooves (G1-G4). When the piston plate (20) is unlocked by the unlocking member (50), the piston plate (20) is moved within the body section (12) along the grooves (G1-G4) by the pressing force of the conical coil spring (40) and reaches an acting position on a skin.
