The invention relates to a dispenser comprising an outer container (300), an internal vessel (200) for storing contents and inserted inside the outer container (300), and a pumping part (100) combined in an upper part of the internal vessel (200) and for discharging the contents in the internal vessel (200) ; the internal vessel is composed with a material capable of the contraction and expansion; a plurality of wrinkles (210) are formed through a blow injection manner; and the connecting rod (220) for coupling with the pumping part (100), an elastic steel band (420) formed in the outer circumference of the internal vessel (200), and a plurality of an elastic steel pieces (421) formed by cutting out a part of the steel band (420) to stand are formed onto the upper part of the internal vessel, respectively;
the elastic steel piece (421) is gradually risen as the contents within the internal vessel (200) is gradually discharged, as maintaining a state where an end part reaches in contact with each other with an inner surface of the outer container (300);
the contents is discharged (or exhausted) by the compressed air (301) by filing between the outer container (300) and the internal vessel (200).
