Abstract: A dosing device for a flowable composition for use in association with a gable top container having at least one angled upper surface. The dosing device has a bottom, a first sidewall connected to the bottom, preferably a second sidewall connected to the bottom and the first sidewall, and means for affixing the dosing device to a gable top container such that the device rests on an angled upper surface of the gable top container. The second sidewall may be trapezoidal in shape or in the alternative, oriented at an obtuse angle relative to said first sidewall. Preferably, the means for affixing the dosing device to the container is a channel for receiving a vertical ridge extension from the top of the gabled container. A kit for containing and dosing a flowable composition that includes a dosing device and a gable top container. Preferably, when the dosing device rests on the angled upper surface it provides a planar surface that is substantially perpendicular to a planar sidewall of the container.
