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.
A liquid chemicals injector comprising: (a) a liquid container having (i) a container body including an opening and a deformable liquid-containing portion, said container body containing a liquid therein, (ii) a cap integrally formed with or fixedly connected to said opening after said liquid is charged in said container body, said cap having a base portion continuous to said opening, a thin-wall portion continuous to said base portion, a top portion having a diameter and being continuous to said thin-wall portion, and at least one horn plate portion extending radially outwardly beyond the diameter of said top portion, and (iii) a cap opener provided around and being rotatable with respect to said cap, said cap opener having at least one craw plate extending radially inwardly from an inner wall of said cap opener to be in contact with said horn plate portion when said cap opener is rotated, an opening being formed in said cap opener after twisting said cap opener relative to said cap and thereby cutting said thin-wall portion, said opening allowing exhaust of said liquid therethrough; and (b) a catheter telescopically engaged with said opening of said container.
