Abstract
A venting cap liner used in a pressurized container closure arrangement. The cap liner includes a multi-layer sandwich structure having a first layer and a generally flat resilient intermediate layer. The layers include at least one perforation extending through the layers to enable gas flow therethrough. The first layer has a first surface including at least one channel extending from one edge of the first layer to another edge of the first layer. The intermediate layer is responsive to a gas pressure level in the container such that, at a first selected pressure level, the perforation extending through said second layer opens to allow gas to flow through the perforation and at a second selected pressure level, the intermediate layer expands to close the perforation thereby resisting gas flow.
