An object is to provide a cap that can be flexibly designed, such as a cap that can be prevented or reduced from being increased in volume when the lid member has been attached to the cap body, while at the same time providing a capability to increase the distance between the lid member and the cap
An object is to provide a cap that can be flexibly designed, such as a cap that can be prevented or reduced from being increased in volume when the lid member has been attached to the cap body, while at the same time providing a capability to increase the distance between the lid member and the cap body when the elastic member has been restored, as well as providing a container equipped with the cap. Provided is a cap and a container with a cap, which includes a cap body (10), a lid member (20), an elastic member (30) that couples the lid member (20) to the cap body (10), and a coupling member (40) that couples the lid member (20) to the cap body (10), in which: the elastic member (30), which has been elastically deformed, is restored during at least part of the movement of the lid member (20) away from the cap body (10), thereby enabling the lid member (20) to be held away from the cap body (10); and the coupling member (40) is connected to the cap body (10) via a first hinge mechanism (41) and connected to the lid member (20) via a second hinge mechanism (42) that has an axis parallel to an axis of the first hinge mechanism (41).

The cap according to claim 2, wherein the pour spout opening is disposed at a position close to a first end of the cap body, and the elastic member is connected to the cap body at a position closer to the first end of the cap body than the coupling member is. 4. The cap according to claim 2, wherein the pour spout opening is disposed at a position close to a first end of the cap body, and the coupling member is connected to the cap body at a position closer to the first end of the cap body than the elastic member is. 5. The cap according to claim 1, wherein the cap body includes an engaging stopper member that engages with the coupling member in order to stop the coupling member from being, pivotally moved by the first hinge mechanism, when the lid member is moved close to the cap body, and the engaging stopper member includes a support part that supports the second hinge mechanism with the coupling member held in engagement with the engaging stopper member. 6.
