1. A device for delivering a fluid comprising:
- a housing having an interior region and an opening;
a quantity of fluid within the interior of housing;
means for causing a pressure differential between the interior region of housing and the immediate surroundings of the housing, wherein the pressure differential, in turn, forces a predetermined quantity of fluid from within the interior region of the housing to the opening; and
means associated with the opening for controlling the flow of fluid through the opening.

53. A restrictive opening for controlling the passage of fluid therethrough comprising:
-
a restrictor plug having an outer surface, a first end and a second end;
a receptacle having an inner surface, a first end and a second end; and
a groove disposed on one of the inner and outer surfaces extending from the first end to the second end thereof, wherein a tunnel is defined by the cooperation of the groove and the outer surface upon positioning of the restrictor plug and the receptacle into operative engagement to, in turn, permit the passage of fluid from the first end to the second end of the restrictor plug in a controlled manner. - View Dependent Claims (54, 55, 56, 57, 58, 60)
