Containers are provided and include a container body having an opening extending into a hollow interior, and a cap extending across the opening. The cap has an inlet port with an inlet valve configured to couple to a fluid source such that fluid can be delivered through the inlet valve to pressurized the hollow interior of the container body. The cap also has an outlet port with an outlet valve having a cracking pressure at which the outlet valve is configured to move from a closed configuration to an open configuration to dispense fluid from the hollow interior, and a closing pressure at which the outlet valve is configured to move from the open configuration to the closed configuration to prevent fluid from passing therethrough. The cracking pressure is greater than the closing pressure.

A water dispenser is provided. The water dispenser may include a main body, a rotator installed to be rotatable in a horizontal direction in the main body and including a water discharger, a rotation guide rail having a predetermined curvature within the main body, and a rotation guide protrusion provided in the rotator and slidably coupled to the rotation guide rail to guide rotation of the rotator.
