ABSTRACT:
A thermal beverage container and a lid therefor are provided. The container includes an insulated reservoir for storing and dispensing liquid. A spout is located at the base of the container and is in communication with the reservoir. A dispensing arm is operable to open a valve upon actuation thereof to permit liquid to be expressed from the reservoir via the spout. The container has an open upper end onto which a lid is threadedly secured. The open upper end of the container defines a neck of reduced diameter relative to the reservoir. The neck has a groove formed therein which extends from the reservoir to the upper surface of the container. The lid is complementary to shape to the opening in the container and thus, includes a plug for seating in the neck. However, the groove is not filled by the plug. A funnel-shaped, centrally located passage is formed through the lid and supports a floatable ball. The passage permits liquid to be poured into the insulated reservoir without removal of the lid. A vent hole radially displaced from the passage is also formed through the lid and communicates with the groove to improve air flow from the reservoir to the exterior of the container upon the pouring of fluid therein.
