Fluid dispensing unit
A fluid dispensing unit having a housing in which is carried a fluid-containing ampoule and a porous pad secured to the underside of the housing has its structural integrity enhanced by a central planar depression formation in the housing top wall to thereby facilitate rupturing the ampoule without hazard of broken glass puncturing the housing walls. An improved porous pad structure also is provided.
