Abstract
A container lid composed of a plastic material comprising a main lid member and a slide member is disclosed, as well as a method of constructing and a mold for forming same. The main lid member has supporting guideways between which the slide member is situated, and the guideways are angled relative to the plane of the main lid member so as to hold the slide member on the lid. At least one aperture is provided for dispensing or collecting the container contents, the aperture being located at a point on the main lid member such that at least a portion of the slide member can be moved along the path between the guideways to a position covering the aperture. The slide member has: (1) a finger engageable portion for moving the slide between a closed position over the aperture and an open position in which the aperture is exposed; and (2) a formed recess which protrudes from its lower surface. The dimensions of the recess correspond substantially to the dimensions of the lid aperture for forming a tight-fitting lid closure when the slide member is in the closed position over the lid aperture.
