A liquid accommodating container includes an inner layer constituting a liquid accommodating portion for accommodating liquid therein; an outer layer having an inner shape substantially equivalent to an outer shape of the inner layer, the outer layer being provided with an air vent for fluid communication between a space between the inner layer and the outer layer with an ambience; a liquid supply portion for supplying the liquid out of the liquid accommodating portion, wherein with supply of the liquid through the liquid supply portion, the inner layer peels off the outer layer, wherein the inner layer and the outer layer are contacted, in a first region, with each other with such a force that the inner layer is peelable from the outer layer by change of an inner pressure, and the inner layer and the outer layer are contacted, in a second region, with each other with a force which is larger than that in the first region, by which the inner layer peels off the outer layer in the second region after the inner layer peels oft the outer layer in the first region.
