Drinking container and lid

Abstract

A lid for use with a drinking container including a vessel having an internal space to hold a base liquid and an opening to the internal space. The lid has a body with an engagement portion configured to engage with the drinking container at the opening to close the opening, and defines a flowpath from an inlet configured to receive the base liquid from the internal space and an outlet, e.g., so a user can drink the base liquid from the vessel by way of the flowpath. The flowpath can include a cavity configured to receive a cartridge to treat the base liquid that is inserted into the cavity via the outlet, e.g., the cartridge can include an additive such as a flavoring for mixing with the base liquid. The flowpath and cartridge can accommodate drinking from the vessel in an upright position, e.g., such that the inlet of the flowpath is below the outlet. An adjustable length portion may define the inlet of the flowpath and may accommodate differently sized vessels.
