Spill preventing container lid

A spill-preventing lid for a container comprising:

• a lid body having a top, a bottom and a peripheral flange;
• a drink opening in said lid body;
• and
• a spill-preventing baffle, said baffle comprising a closed wall extending downwardly from said bottom of said lid body, said baffle having an open top, a solid bottom, a height from said open top to said solid bottom, and a width which is generally perpendicular to said height, said height being greater than a maximum dimension of said width, said open top of said baffle communicating with said drink opening, at least one aperture extending through said solid bottom, and a passage leading through said baffle from said bottom to said open top, allowing liquid to flow from said container into said baffle, though said passage defined by said baffle and to said drink opening, each of said apertures through said bottom being substantially smaller in dimension than the dimension of said drink opening, whereby liquid which is splashing is deflected by said baffle and said apertures reduce the energy of liquid passing therethrough, whereby said height of said baffle in relation to said greatest width-wise dimension of said baffle inhibits said splashing liquid from flowing into said passage to said drink opening without the need for a cap or a lid over said drink opening.

A spill-preventing, nestable lid for a container comprising:

• a lid body having a top, a bottom and a peripheral flange;
• a drink opening in said lid body;
• and
• a spill-preventing baffle, said baffle comprising a closed wall extending downwardly from said bottom of said lid body, said baffle having an open top and a bottom, said open top of said baffle communicating with said drink opening, a plurality of elongate non-contiguous perforations in said bottom, and a passage leading through said baffle from said bottom to said open top, allowing liquid to flow from said container into said baffle, through said passage defined by said baffle and to said drink opening during drinking, each of said perforations in said bottom being substantially smaller in dimension than the dimension of said drink opening, wherein an opening area of each of said plurality of perforations is less than about 25% an opening area of said drink opening and wherein said baffle has a height from said open top to said bottom, and a width which is generally perpendicular to said height, said height being greater than a maximum dimension of said width, whereby liquid which is splashing is deflected by said wall and bottom of said baffle and whereby said perforations reduce the energy of liquid passing therethrough, whereby said baffle inhibits said splashing liquid from flowing into said passage to said drink opening without the need for a cap or a lid over said drink opening;
• and wherein said closed wall of said baffle tapers inwardly moving from said top to said bottom thereof, thereby permitting mating portions of said lid to be nested onto mating portions of a second lid in order to minimize a volume of space occupied by said lid and said second lid, and wherein, when said lid is nested onto said second lid, said baffle of said lid and a baffle of said second lid fit into one another, and said lid body of said lid and a lid body of said second lid are positioned proximate to one another, thereby reducing a height of said lid and said second lid when nested.
