Definitions

  • the capillary passage 20 has a uniform diameter along its length which is dimensioned to permit flow therethrough by capillary effect only.
  • the neck 22 is formed of relatively thick material in comparison to the diameter of the capillary passage 20, to resist deformation of the diameter of the capillary passage 20 as ejecting pressure is applied to the reservoir 16, so as to provide a uniform flow of liquid from the reservoir 16 through the capillary passage 20 irrespective of the pressure applied by hand to the reservoir 16 within a reasonable range.
  • the flow is controlled primarily by surface forces in the passage 20.
  • Figures 4 and 5 show some variation to the structure shown in Figures 2 and 3.
  • the capillary passage 20 may be made shorter than the length of the neck 22, to provide a cavity 47 in the neck. This modification does not affect the effectiveness of the device, but enables molding of the dropper 10 to be more readily effected.
  • the dropper 100 is molded in a two-­part mold, which leaves a visible mold part line 114.
  • this inconsistency problem is overcome.
  • the prior art dropper 100 has no mechanism for remolding the tip.
