ABSTRACT:
A liquid container comprises a container body (2) having an opening (12) and a liquid-containing portion (2a), the container body containing liquid (W) therein; a cap (3) integrally formed with or fixedly connected to the opening after the liquid is charged in the container body, the cap having a base portion (3a) continuous to the opening, a thin-wall portion (3b) continuous to the base portion, a top portion (3c) continuous to the thin-wall portion, and at least one horn plate portion (13) continuous to the top portion, the horn portion radially outwardly extending beyond the diameter of the top portion; a cap opener (5) provided around the cap to be rotatable with respect to the cap, the cap opener having at least one craw plate (15) radially inwardly extending from inner wall of the cap opener to be in contact with the horn plate when the cap opener is rotated, an opening (5d) being made in the cap opener so as to exhaust the liquid (W) therethrough after the thin-wall portion is cut by twisting the cap opener relative to the cap. With this structure, leakage of liquid is effectively prevented.
