Abstract

A drink container with torque-limiting lid is provided. The drink container includes a lid that can be threadably coupled to a container body having a volume to hold fluids. The lid can include an inner lid assembly concentric with an outer lid assembly. The inner lid assembly can include a multiple ratchet teeth along an outer perimeter and the outer lid assembly can include one or more ratchet pawls along an inner perimeter and configured to engage the ratchet teeth. Rotational force on the outer lid assembly can be transferred to the inner lid assembly from the ratchet pawls to the ratchet teeth to threadably couple the inner lid assembly to the container body. Once a torque limit is reached, the ratchet pawls can slip along the ratchet teeth preventing further tightening of the inner lid assembly to the container body.
