PROBLEM TO BE SOLVED: To provide a measuring and pouring cap which enables a desired quantity of content fluid to be accurately poured out while a poured quantity is checked, only by tilting a container body.SOLUTION: A measuring and pouring cap 10, which is used by being attached to a mouth and neck part of a container body 11, includes a reservoir measuring chamber 12 which is arranged in the state of covering a tip outflow opening of the mouth and neck part of the container body 11. The reservoir measuring chamber 12 is formed by having its periphery surrounded by a bottom wall part 15 provided with a plurality of outflow ports 13 and 14, and an outer peripheral wall part 17 provided with a pour spout 16. The plurality of outflow ports 13 and 14 comprise the main outflow port 13 which communicates with the pour spout 16, and the auxiliary outflow port 14 which communicates with the reservoir measuring chamber 12. The main outflow port 13 and the auxiliary outflow port 14 are formed in such a shape that a flow rate of the content fluid flowing out into the pour spout 16 from the main outflow port 13 and a flow rate of the content fluid flowing out into the reservoir measuring chamber 12 from the auxiliary outflow port 14 establish a linear relationship, when the content fluid is poured out by tilting the container body 11. |
