Abstract:
To provide a discharge cap capable of suppressing the force of content splashing at the time of discharge, with a simple structure, in which a separation pressure of a check valve from a valve seat is unchanged, and in which the check valve is separated from the valve seat not with a stroke amount more than necessary even in the case where a container is pressed more than necessary.SOLUTION: A discharge cap 100 includes a fitting wall part 113 and a discharge cylinder 114 for discharging a content P, and it also includes a valve chamber 130 partitioned between the inside of a container and the discharge cylinder 114. In the valve chamber 130, a bottom part 133 having a supply cylinder 135 for taking out the content P and a valve seat 134, and a check valve 132 are provided. The check valve 132 has a valve seal surface 138a which can come into contact with the valve seat 134, and below a contact part between the valve seat 134 and the valve seal surface 138a, an inflow adjustment chamber 142 is provided which has a lower opening 135a for communicating the inside of the container and the valve chamber 130.SELECTED DRAWING: Figure 1
