PURPOSE:To prevent micro organisms, etc., from entering a container from outside by sealing a liquid outlet for communicating between inside and outside the sealed container with a hydrophilic filter and sealing an air hole with a hydrophobic filter respectively. CONSTITUTION:A liquid container comprises a flexible container body 1 for preserving liquid 7, a cap 2 provided on an opening of the container body 1 for sealing the container body 1, a hydrophilic filter 3 to be attached to a liquid outlet 10 of the cap and a hydrophobic filter 5 provided on an air hole 3, wherein the liquid 7 in the container 1 is discharged outside the container through the hydrophilic filter 3. When the container 1 is placed upside down and pushed, the liquid 7 in the container 1 transmits through the bag-like filter 3 to be discharged from the liquid outlet 10. Since the thin porous filter 5 for closing the air hole 4 is hydrophobic, the liquid does not transmit through the filter 5 unless a specific pressure or higher is applied. Micro organisms and bacteria, etc., contained in the atmosphere flowing through the air hole 4 in order to eliminate a negative pressure in the container are captured by the filter 5 and will not enter the container. |
