Both members were integrally formed of a synthetic resin material, respectively. In the state shown in FIG. 1, the outer periphery of the plug lid member 8 is covered with the sealing member 23, and the strip 17 cannot be removed from the engaging projection 19, so that the plug cannot be opened. Also, since the shielding cylinder 26 is covered with the thin cylinder 27 from the lower end surface to the upper surface of the shoulder 5,
If the fitting cylinder portion 10 is removed from the container body 2 using a screwdriver or the like, a trace of deformation by the screwdriver or the like remains on the thin cylinder portion 27, and therefore, it cannot be illegally pryed open. When opening, the shielding tube 26 is pulled up to break the connecting portion 25, and is removed from the container body 2 as shown in FIG. Thereafter, the strip 17 is detached from the engaging projection 19, and the cap 14 is opened as shown in FIG. When the cap is closed from this state, the cap 14 is folded down so that the stopper tube 15 is fitted into the pouring hole 12 and the engaging projection 19 is fitted into the through hole 18 so as to engage with the strip 17. The child 19 is locked. As shown in FIG. 1, a liquid container 1 according to the present invention comprises a container, a stopper member, and a sealing member. It is molded integrally with resin material. [0008] The container body 2 extends from the outer peripheral edge of the bottom wall 3 to the body 4.
And the mouth and neck 6 is erected from the trunk via the shoulder 5. In the illustrated example, the mouth and neck 6 is made thicker than the body 4, and a wide band-shaped ridge 7 is provided around the outer surface of the upper end. The container 2 is made of synthetic resin or glass. The stopper member 8 has a fitting tube portion 10 fitted and fixed to the outer surface of the mouth and neck portion 6 in a liquid-tight manner, and is poured into a central portion of a top wall 11 which closes an upper surface of the fitting tube portion. A hole 12 is formed, and a stopper tube 15 hanging from the center of the lower surface of a cap 14 attached to a rear upper end of the fitting tube portion 10 via a thin hinge 13 is inserted into the pouring hole 12.

In the illustrated example, as shown in FIGS. 2 and 5, a plurality of small-diameter ribs are used as the connection portion 25 to connect the short tube 24 and the shielding tube 26. It may be a thin portion provided with a break line perimeter. In addition, as shown in FIG. 2, an outward flange 28 used as a fingerhold when pulling up the shielding cylinder and breaking the connecting portion 25 is provided around the upper outer surface of the shielding cylinder 26. As described above, in this embodiment, the connecting portion
The breaking of 25 was performed by raising the shielding cylinder 26,
This may be performed by twisting the cover 26 in the lateral direction, or by pushing the shielding tube 26 downward by one push. When the connection part 25 is broken by pushing down the shielding cylinder 26, the thin cylinder part
It is more preferable that a plurality of slits cut from the lower end face are arranged in 27. According to the present invention, the sealing member 23 is formed as described above, and the sealing member 23 is provided to protrude outward from the outer peripheral surface of the short tube 24 fixed to the outer surface of the lower end portion of the fitting tube portion 10. The shield tube 26 is erected through the easily breakable connecting portion 25 and the deformable thin tube portion 27 is suspended from the lower end surface of the shield tube to a position close to or in contact with the upper surface of the shoulder portion 5. Also, regardless of the size of the sealing member 23, pull up the shielding cylinder 26,
It is possible to provide the liquid container 1 which can be opened by any operation such as twisting in the lateral direction or one-pushing downward, and which can be easily opened. Further, since the strip 17 which is fitted to the engaging projection 19 and prevents the opening of the cap 14 is covered by the shielding cylinder 26, the inner solution can be prepared without special packaging such as a shrink pack. Since the strip 17 is suspended from the front surface of the cap peripheral wall, the strip 17 can be used as a knob for opening and closing the cap 14 after the shield tube 26 is removed. Furthermore, the deformable thin cylindrical portion 27 is hung from the lower end surface of the shielding cylinder 26 to a position close to or in contact with the upper surface of the shoulder portion 5, and the fitting cylindrical portion 10 is moved out of the mouth and neck portion 6 using a screwdriver or the like. When it is performed, the deformation mark is left on the thin cylindrical portion 27, so that it can be prevented from being illegally pryed open during the distribution process.
