One-piece splash and spill resistant lid

Abstract

A one-piece disposable cup lid enables drinking while inhibiting splashing and spilling by blocking straight-line paths through the lid and dispensing beverage through a well. A drinking spout can include a well having a sidewall, a bottom and a penetration into the cup, or a sloping lid section can intersect a raised rim to create a well therebetween, with a penetration in the sloping section or the rim configured to block straight-line paths, for example by upwardly hinging of a flap or depressing half of a split, convex bubble. Embodiments include baffles that force a beverage to flow through a convoluted path and/or through chambers before being consumed. Baffles can be formed in place, or by hinged movement of flaps after forming. Textures and/or protruding structures can intercept, direct, and/or influence surface tension as beverage flows across surfaces. Vent hole sizes and locations can further limit flow and spilling.
