Abstract
Abstract A cover that overlies the opening tab on an easy open to shield the opening tab and underlying elements from accumulations of dirt or other foreign substances. The clean cover is mounted so as to be nondetachable from the opening tab or other structure of the container, so that the clean cover cannot become a separate item of litter. The clean cover is flexible and can be depressed or otherwise sufficiently manipulated with the tab as necessary to open the container, and may slide or otherwise move with the tab as part of the normal container-opening function. The clean cover may be physically attached to the opening tab, or may alternatively be attached to the container end panel on which the tab is mounted.
