Abstract
Abstract A plastic container includes a one piece plastic body portion having a cylindrical outer wall and a bottom wall, and a one piece cap portion having a cylindrical outer wall and a top wall. The outer wall of the cap has a snap fit around a portion of the outer wall of the body to hold the cap on the body. The top wall and the bottom wall have a plurality of small holes therethrough which allow gases and vapors to enter the container but prevent the contents of the container from leaving the container. The holes are in the shape of square truncated pyramids with the larger area ends of the holes being at the inside surface of the respective walls. A label may be secured around the cylindrical outer surface of the container across the junction between the body and the cap to help prevent removal of the cap from the body.
