ABSTRACT:
An adjustable spoon or scoop with a measuring container on each end. The spoon has a sliding cover with dams for adjusting the volumes in the measurement containers at both ends. The cover can be easily snapped off of the spoon body to separate the parts for easy washing. The dimensions of the containers at opposite ends of the spoon are set to cover different volume ranges; for example, 1/8 teaspoon to 1 teaspoon at one end, and 1 teaspoon to 1 tablespoon at the other end. Coordinated indicia are provided to indicate the measurements corresponding to each position of the slider. The dimensions of the measurement containers are determined so that a standard fractional measurement will be provided at both ends of the spoon by each of a plurality of sequential slider locations. The body has a slender central portion extending between the measurement containers. An internal vertical rib is used to strengthen the central portion while keeping it slender, and a second rib, perpendicular to the first rib, serves as a dam to impede the flow of liquids from one container to the other.
