USPTO Abstract

A liquid applicator having a container (2) which can be broken at its thin-walled portion (5), into a main body (3) and a cap (4). The main body (3) has a space filled with a liquid (8). A columnar liquid-applying member (6) is located in the container (3), partly located in the main body (3) and partly in the cap (4). The liquid-applying member (6) is connected to the main body (3) by a coil spring (9) arranged in the space. The liquid-applying member (6) is supplied with the liquid (8) from the space and is impregnated with the liquid (8). A hydrophobic film (7) covers the substantially entire circumferential surface of the liquid-applying member (6). The film contacts the inner surface of the main body (3), but can move in the axial direction thereof together with the liquid-appliying member (6). The film (7) prevents the liquid from being scattered around when the container (2) is broken at its thin-walled portion (5).
