Abstract

See full text

A fluid applicator in which the internal pressure of a fluid tank can selectively be increased, and the fluid to be applied is prevented from being discharged excessively during application. A cap is provided with a short first inner barrel and a long second inner barrel, so that, when the neck of the applicator is inserted into the short first inner barrel to seal the tip, the pressure rise in the first inner barrel is adapted to be small so as not to substantially increase the internal pressure of the fluid tank, whereas when the neck is inserted into the long second inner barrel, the pressure rise in the second inner barrel is adapted to be great so as to increase the internal pressure of the fluid tank. Alternatively, the applicator may be provided with a pressurizing device having a plurality of sealing barrels of different lengths.
