PROBLEM TO BE SOLVED: To provide a synthetic resin container lid in which, even though elastic deformation or displacement of a tamper-evident skirt part (22) can be sufficiently suppressed by bringing a region which is an upper side of engagement means (34) on an inner peripheral surface of the tamper-evident skirt part into contact tightly with an outer peripheral surface of an engagement jaw part (46) on a neck part (42) of a container, when opening the neck part, flow-down of a cleaning fluid which is acted to the outer peripheral surface of the neck part is permitted, therefore the cleaning fluid is prevented from adhering and remaining on the outer peripheral surface of the tamper-evident skirt part, reliably, and to provide a combination of the synthetic resin container lid and the container.SOLUTION: Plural grooves (40) extending in a central axial direction, are provided with intervals in a peripheral direction in a region which is an upper side of engagement means on an inner peripheral surface of a tamper-evident skirt part. The grooves regulate a liquid discharge path (50) for permitting flowing of a fluid between the inner peripheral surface of the tamper-evident skirt part and an engagement jaw part of a neck part.SELECTED DRAWING: Figure 3 |
