As described above, according to the spouting cap 1 according to the present embodiment, the two spouting holes 21 arranged side by side in the left-right direction (horizontal direction) are arranged in the horizontal direction as diagonally upward from the connection path 32. The angle θ formed by the central axis O2 of the two spout holes 21 is 35° or more and 60° or less when viewed from the top and bottom.
Therefore, the liquid content enters the oral cavity from the two spout holes 21 at an appropriate distance from each other in the left and right direction, making it difficult to reach the vicinity of the entrance of the throat, and allowing the liquid content to remain in the oral cavity at an appropriate distance. It can be poured in any position.

Since the two spout holes 21 communicate with one connection path 32 provided between the closing wall 15 of the cap body 11 and the top wall 13 of the spout plug 12, the squeeze deformation of the body is prevented. Sometimes, there is a difference in the flow rate of the content liquid poured out from the two spout holes 21, and the force of the content liquid poured out from the spout hole 21 is strong, making it easy for the content liquid to reach near the entrance of the throat. It is possible to suppress each of the following.

When the lid body 22 is rotated upward around the hinge portion 23 to open the spout hole 21, the first engaging portion 25a and the second engaging portion 12a engage with each other, so that the spout stopper 12 is opened. moves from the closed position to the open position, the inside of the supply cylinder 33 (communication hole 16) and the spout hole 21 communicate through the connection path 32, and the content liquid can be poured out, and the lid body 22 is moved to the hinge part 23. When the spout hole 21 is closed by rotating it downward, the first engaging portion 25a and the second engaging portion 12a engage with each other, so that the spout stopper 12 changes from the open position to the closed position. As a result, communication between the inside of the supply cylinder 33 and the spouting hole 21 through the connection path 32 is cut off.
As described above, as the lid body 22 is rotated in the vertical direction around the hinge portion 23, the spout tap 12 can be moved in the vertical direction between the closed position and the open position, resulting in excellent operation. It can be made to have a certain gender.

Since the spout stopper 12 can be positioned in the closed position, even if an unexpected external force is applied to the body of the container body W during storage without pouring out the liquid, the liquid will not flow through the spout hole 21. leakage can be prevented.
