Spill-proof lid for container
The present disclosure provides a lid that has a design that is configured to enable drinking from any point along the perimeter of the lid while at the same time preventing liquid to escape from the lid when a user is not drinking (i.e., spill proof). The lid has a plurality of slits around at least a portion of the lid.
1. A container lid configured to engage with a container,
the lid comprising:
a top planar surface;
a lip positioned around the circumference of the top planar surface;
a cylindrical mounting base extending from an outer edge of the top planar surface, wherein the cylindrical mounting base includes a cylindrical wall, wherein the cylindrical wall is substantially perpendicular to the top planar surface, wherein an outer surface of the cylindrical wall is configured to engage with a portion of an inner surface of an opening of the container, wherein the top planar surface and the cylindrical mounting base form an interior cavity of the lid; and
a plurality of slits extending through the thickness of the lip, wherein a first end of the slit is located on an outer surface of the lip, wherein a second end of the slit is located on an inner surface of the lip, wherein the slit is in fluid communication with the interior cavity,
wherein, absent negative pressure applied to the slits, the slits remain closed.
2. The container lid of claim 1 , wherein the outer surface of the cylindrical wall includes a plurality of ribs extending along at least a portion of the circumference of the outer surface.
3. The container lid of claim 1 , wherein engagement between the outer surface of the cylindrical wall and the inner surface of the container forms a waterproof seal.
4. The container lid of claim 1 , wherein the lip is raised relative to the top planar surface of the lid.
5. The container lid of claim 1 , wherein the plurality of slits within the lip extend radially from an inner edge of the lip to an outer edge of the lip.
6. The container lid of claim 1 , wherein the plurality of slits are linear.
7. The container lid of claim 1 , wherein the lid is made of silicone.
8. The container lid of claim 1 , wherein the lid is one piece of material.
9. The container lid of claim 1 , wherein the lip has a thickness of 0.3 mm to 0.7 mm.
