Abstract:
An aeration valve for a can comprising:a sleeve configured to be inserted into a top opening of the can, the sleeve including an inner wall surrounding an axial bore, a top surface facing generally away from the can when the sleeve is inserted, and a lateral bore positioned on a lower portion of the sleeve adapted to be inserted into the can; a rotatable insert positioned within the axial bore, the insert including a plate and a projection formed centrally on the plate; and a holder in which the projection engages; wherein the projection includes a first flat surface in a spaced apart relationship with the inner wall to form a first channel therebetween; wherein the holder includes a first sealing surface adapted to mate with the inner wall of the sleeve to thereby seal the lateral bore and a second flat surface in a spaced apart relationship with the inner wall to form a second channel fluidly connected to said first channel; wherein the plate extends over a top surface of the sleeve and includes a bottom surface overlying the top surface of the sleeve and includes a first recess fluidly connected to the first channel and an exterior of the valve, so that when the insert is rotated to position the first and second flat surfaces opposite the lateral bore, the interior of the can is aerated through the second channel, the first channel and the first recess.
