ABSTRACT:
The device for applying a liquid or semi-paste substance is provided with a hermetically sealed refill (1) containing said substance and removably disposed within a body (5), a head (7) for the application of the substance being removably fixed at one end of the body. A conical tube (9) is provided for putting the application head (7) into communication with the interior of the refill (1) and the other end of the body (5) is provided with a closure end-cap (12).
The refill (1) is closed at the end opposite to the application head (7) by a capsule (4) of perforatable material and the closure end-cap (12) carries a hollow needle (22, 29) which is capable of perforating said capsule (4, 26) when the refill is placed within the body (5). The hollow needle (22) communicates with air-pressurization means (17) consisting of a thumb-actuated hemispherical cap carried by the closure end-cap (12).
