The lid (10) includes a lid lip (16) having a generally inverted U-shape and the bowl (20) includes a bowl lip (26) having a generally inverted U-shape such that the lid lip (16) and the bowl lip (26) interfit, forming mutually opposing surfaces, with the lid lip (16) superposing the bowl lip (26). At least one of the bowl lip (26) and the lid lip (16) includes a seal in firm contact with the opposing surface, with the seal contacting the opposing surface in a small area relative to a total surface area of the bowl lip (26).
摘要:
A selectively detachable container lid includes a center panel and a peripheral sealing lip surrounding the panel. The peripheral sealing lip has a generally inverted U-shaped cross section so as to define a channel into which a bowl rim fits. The lid also includes at least one ridge formed between the panel and the peripheral sealing lip. The ridge is interrupted by at least one gap. The ridge and the peripheral sealing lip partially overlap when viewed in a direction substantially normal to the panel. The ridge also abuts the bowl when the lid is placed loosely on the bowl. Also disclosed is a container that includes such a lid.
