The present invention provides a package such as a cylindrical can for containing a particulate product, such as roast and ground coffee, under pressure. The package automatically releases the pressure upon opening while preventing the escape of the particulate product. The package is made from a container having a closed top, a closed bottom, and an enclosed body between the top and the bottom. The package includes a venting member disposed within the container near the top. One end of the venting member abuts against the body of the container along its perimeter and another end abuts against the top of the container along its perimeter. The package further includes a channel between the venting member and the container. When the container is initially opened with a can opener, the top of the container is punctured in an area above the channel. The pressure is then released from the container into the channel and out of the package while the particulate product is prevented from escaping.
