A container that stores and dispenses a fluid agent container comprises a flexible body portion, a duckbill valve, and a cap. The flexible body portion defines an internal cavity; the internal cavity is configured to store the fluid agent therein; and an opening is defined in the body portion. The duckbill valve is coupled to the opening of the body portion, with the duckbill valve being configurable between an open configuration and a closed configuration such that the duckbill valve prevents the flow of the fluid agent out of the internal cavity when the duckbill valve is in the closed configuration and permits the flow of the fluid agent out of the internal cavity when the duckbill valve is in the open configuration. The duckbill valve is prevented from being motivated into the open configuration when the cap is coupled to the body portion.
