Abstract: The invention is a temporary cover for a paint can's rim, for protecting the rim from paint or liquid while pouring. The invention is substantially similar lengthwise/an extruded part. An embodiment's cross-section (FIG. 15) can be a substantially C-shaped portion (27) plus a substantially narrow-tipped elongated flat portion (from 24 to 26), for a total shape like a “b”, with the b's circular section being open on the front like a “c”. When the cup portion is pressed/secured on to a paint can rim: the cup's open side faces substantially peripherally and/or downward and the tip of the elongated portion faces substantially upwardly (FIG. 23). The invention can be made a size and shape to also be stored on a can's metal wire paint can handle (handle positioned inside of the C-shaped cup). Placed on the can handle, the cover can add handle cushioning for carrying the paint can.
