PURPOSE:To obtain a measuring cap that can prevent a measured content from running over, can improve a measuring accuracy, and can be easily loaded on/unloaded from a bottle by specifying a relation among the capacities of a liquid content measured in order in a preliminarily measuring chamber in an inverted state, in the preliminarily measuring chamber in an erected state, and in a finally measuring chamber in an erected state. CONSTITUTION:A pouring port 110 is provided on the top of a finally measuring chamber 120. The finally measuring chamber 120 is communicated with a preliminarily measuring chamber 130 through a second communicating tube 140. The preliminarily measuring chamber 130 is communicated with a bottle 200 through a first communicating tube 150. In this measuring cap, the upper ends of the first and second communicating tubes 150, 140 are positioned so that a first capacity V1 of a liquid content measured in the preliminarily measuring chamber 130 in an inverted state, a second capacity V2 of a liquid content measured in the preliminarily measuring chamber 130 in an erected state, and a third capacity V3 of a liquid content measured in the finally measuring chamber 120 in an erected state can meet a relation of V1>V2>V3. In addition, as the first communicating tube 150, a communicating tube with a partition wall 151 dividing a flow path is used. |
