Lid and method of using a lid

A lid comprising:

• a body having a top surface and a planar bottom surface opposite said top surface, and a groove in said top surface, said top surface including a generally planar inner portion and an outer portion concentric with and surrounding said generally planar inner portion, wherein a surface of the outer portion distal from said generally planar inner portion defines an outer periphery edge of the body, and said groove in said top surface separates the top surface generally planar inner portion and the top surface outer portion, wherein said groove is concentric with and surrounding said generally planar inner portion and said groove is concentric with and surrounded by said outer portion, and wherein said planar bottom surface of said body underlies each of said generally planar inner portion, said groove, and said outer portion of said top surface;
• and
• a flexible skirt integrally joined to the outer periphery edge of the body and extending therefrom and said flexible skirt and said body are a single piece, wherein the flexible skirt includes a front panel and a back panel, the front panel and the back panel are positioned on opposite sides of the outer periphery of the body from each other, and two side panels between the front and back panels, each side panel being shorter than each of the front and back panels;
• and
• an inner recess along an inner perimeter defined by the union of the periphery of the bottom surface of the body and the flexible skirt, the inner recess configured to receive an edge of a container,
• wherein the groove defines a flexible zone which permits the flexible skirt to flip between a first position and a second position, and when said flexible skirt is in said first position said groove has a first width and when said flexible skirt is in said second position said groove has a second width, said second width is narrower than said first width,
• wherein when the flexible skirt is in the first position the flexible skirt projects downward and away from the top surface and an edge of the flexible skirt distal from the body defines a perimeter less than the perimeter defined by the outer periphery edge of the body, and wherein the second position is inverted from the first position.

A method of removably securing a lid to a container, the container including an open end, and the lid including a body having a top surface and a planar bottom surface opposite said top surface, and a groove in said top surface, said top surface including a generally planar inner portion and an outer portion concentric with and surrounding said generally planar inner portion, wherein a surface of the outer portion distal from said generally planar inner portion defines an outer periphery edge of the body, and said groove in said top surface separates the top surface generally planar inner portion and the top surface outer portion, wherein said groove is concentric with and surrounding said generally planar inner portion and said groove is concentric with and surrounded by said outer portion, and said bottom surface of said body underlies each of said generally planar inner portion, said groove, and said outer portion of said top surface, said lid further includes a flexible skirt integrally joined to the outer periphery edge of the body and extending therefrom and said flexible skirt and said body are a single piece, wherein the groove defines a flexible zone which permits the flexible skirt to flip between a first position and a second position and when said flexible skirt is in said first position said groove has a first width and when said flexible skirt is in said second position said groove has a second width, said second width of said groove is narrower than said first width of said groove, the method comprising:

• positioning the lid, with the flexible skirt in the second position, over the open end of the container, wherein the flexible skirt extends in an upward direction from the top surface when the flexible skirt is in the second position;
• securing the lid and the container together by moving the flexible skirt from the second position to the first position by causing the flexible skirt to flip about the flexible zone to cause engagement of the flexible skirt with an outer surface of the container thereby forming a removable attachment and a substantial seal between the lid and the container, wherein the flexible skirt extends in a downward direction from the top surface of the body when the flexible skirt is in the first position.
