The pin (10) has a hollow plastic pin body (13) for accommodating a hard ampoule (11). An open end of the body includes a wall that is sufficiently flexible to break the ampoule in a toolless manner and to produce discharge of the liquid inside the body. An applicator head (15) is placed on an open end of the body. The body comprises a separate cladding layer (13b) in sections for increasing piercing rigidity of ampoule fragments, and holding units close to the open end of the body for holding the applicator head and/or the ampoule in its interior. The cladding layer extends over an entire length of the plastic pin body. Recesses are present in thread turns and increases elasticity of a front end of the pin body. |
