Abstract
A single service container having a plastic body and a non-removable plastic cap. The cap and body are made of materials which are compatible to one another for recycling purposes. A tear strip is defined in the cap by a pair of score lines which extend substantially across the cap. By lifting a pulling member that is integrally formed with the tear strip, the tear strip separates from the remainder of the cap along the score lines and provides the container with an opening through which its contents may be consumed. In this manner, a container is provided which has no components that need to be separated prior to recycling.
