    Abstract: Components of the package are a leakproof container of sufficient size and shape to hold five quarts of motor oil and one engine oil filter and a zip-type, tear-open top to the container with a pull tab.The container is made of a paper-based material which allows interior coating to provide a leak resistant environment once engine oil is drained from an engine into the open container.

Before opening, the container top is a means to contain the five quarts of motor oil and engine oil filter.
