勺子和叉子的容器;勺子和叉子可枢转地安装到容器的顶部的下侧，并且顶部铰接到容器的底部，使得其可以打开以允许勺子和叉子转动到它们穿过容器的端部突出的位置，然后，顶部可以向下闭合，以与容器的底部搭扣配合，从而将勺子和叉子保持在适当位置，并使容器能够用作勺子和叉子的手柄。
A receptacle for a spoon and fork; The spoon and the fork are pivotally mounted to the underside to the top of the receptacle, and the top is hinged to the bottom of the receptacle so that it may be opened to permit the spoon and fork to be turned to a position in which they protrude through the ends of the receptacle, and the top may then be closed down to a snap fit with the bottom of the receptacle to hold the spoon and fork in place, and enable the receptacle to serve as a handle for the spoon and fork.
