1. A discharging container comprising:

  • a laminated bottle having a mouth part; and

    a cap fitting on the mouth part of the bottle, wherein the bottle comprises an outer layer and an inner layer laminated on an inner surface of the outer layer such as to be capable of delaminating from the outer layer;

    the inner layer is capable of being charged with a liquid content;

    the outer layer has a body part capable of being deformed so as to deflate and recovering its undeformed normal configuration;

    at least one inlet is formed in the outer layer to allow ambient air to flow into a space present between the outer layer and the inner layer while the deformed outer layer is recovering the normal configuration, with no valve provided for said at least one inlet;

    the cap has a discharging outlet for discharging the liquid content out of the inner layer; and

    the inlet has an opening area smaller than that of the discharging outlet such that air in the space between the layers is compressed when the body part of the outer layer is deformed so as to deflate, thereby the liquid content is discharged out through the outlet as a result that the compressed air presses inwardly a circumference of the inner layer.
