Abstract
An injection stretch blow molded container is disclosed having an integral tab for hanging the container with the finish end down so as to facilitate removal of the contents of the container. A method of making the container is disclosed which includes the use of an injection molded parison having an integral tab of the size and dimensions desired for the container tab. The parison is then situated in a blowing mold having a pocket for receiving the integral appendage. The parison is stretched until the appendage is received in the pocket in the mold wall and then blown to form the container having a wall conforming to the interior of the blowing mold. A surface of the integral appendage performs the function of the mold wall with respect to a portion of the container.
