Abstract:
There are provided a check valve structure that not only prevents backflow of fluid but does not discharge fluid for unintended pressure in a correct direction, and a squeeze container using the check valve structure. A squeeze container includes a container and a nozzle member attached to an opening of the container. The nozzle member is provided with a check valve structure that is closed in an unloaded state, and that blocks a flow of fluid from downstream and allows a flow of fluid from upstream. The check valve structure is opened when an elastic valve element elastically deforms in two stages due to pressure of fluid from upstream (container).

Claim (Index 3):
The check valve structure according to  claim 2 , wherein\n a recessed portion constituting the communication passage is formed in the downstream support portion.
