Venting closure cap

A closure cap which can be manipulated to dispense container contents and enables venting of any excess pressure which may build up within the container when the closure is in a fully closed position, comprising:

• a central upstanding post having a first substantially cylindrical imperforate peripheral wall portion, a second reduced diameter substantially cylindrical imperforate peripheral wall portion positioned on top of said first wall portion and having a top surface, and a peripheral shoulder portion connecting said first and second wall portions together, said shoulder portion including at least one opening to said post top surface for metering the contents to be dispensed;
• a cap body reciprocally mounted on and about the periphery of said central post and having an aperture whose inner periphery cooperates with said peripheral wall of said second wall portion to provide a closed position and a plurality of dispensing positions for dispensing the contents at a plurality of different rates as said cap body is moved on said post away from said closed position;
• and
• venting means for enabling any excess pressure from within the container to exhaust between said top surface of said peripheral wall and said inner periphery of said cap body to the exterior of the container upon reaching a predetermined pressure within the container when the cap is positioned in said fully closed position.
