A pumping container for blocking air comprises: a container for accommodating liquid contents; a pumping cap, coupled to an inlet of the container, for discharging the contents accommodated in the container to the outside according to a pumping operation; a suction line, coupled to the pumping cap, for sucking in the contents according to the operation of a pumping part; and an air blocking member for preventing the contents remaining in the container from making contact with air, by receiving and collecting air on the inside thereof in a volume equal to that of the contents discharged from the container by the pumping operation. Since the pumping container for blocking air, configured as described above, can always keep the contents accommodated in the container sealed from the outside so as not to be in contact with air, it is possible to prevent the problem of the shelf life of the contents rapidly shortening due to the decomposition or oxidation by contamination of the contents. |

1. An air-blocking type pumping container comprising:
a container (110) for accommodating liquid contents; a pumping cap (120) coupled to an inlet of the container (110) and for discharging the contents accommodated in the container according to pumping operation, wherein in the pumping cap an air inlet (128) is formed through which external air can be introduced into the inside of an air blocking member (130) in the pumping operation; a suction line (140) coupled to the pumping cap (120) and for sucking the contents (105) accommodated in the container according to the pumping operation; and the air blocking member (130) integrally coupled to a lower surface of a coupling cap (124) by means of an O-ring (132) for preventing beforehand the contents (105) remaining in the container (110) from contacting with the introduced air, by receiving the air introduced into the inside of the air blocking member in a volume equal to that of the contents discharged from the container by the pumping operation, wherein the air blocking member (130) has a lower part which is coupled to the suction line (140) so as to surround the line while exposing a suction opening of the suction line (140), and an upper part which is closely contactingly and integrally fixed to the lower surface of the coupling cap (124) facing the inlet of the container by means of the O-ring (132) while surrounding a pumping part (122) of the pumping cap, and the air blocking member is a one piece-type air collection part (130) which is expanded by receiving the air in a volume equal to that of the discharged contents (105). |
