Abstract: The measuring cap-containing, liquid-dispensing container assembly includes a container with interior storage space and upstanding pour spout connected to the space, an annular raised platform peripheral of the spout base and an annular recessed liquid drainage channel between the spout base and platform. The channel preferably has a curved bottom and has a drainage hole communicating with the container storage space. The assembly includes a measuring cap disposed over and releasably secured to the spout by a first seal. The base of the cap abuts the platform and is sealed thereto by a second seal. The first seal can be an annular sleeve depending from the cap top interior peripheral of the spout, and mating threads or mating detents and recesses on the spout exterior and sleeve interior. The second seal is an o-ring in a recess in the cap base and/or platform, or a detent in one of the cap base or platform and a mating recess in the other of the cap base and platform.
