By pulling up a, the pouring hole is opened. After the liquid is poured out, the content liquid is stored by covering the cap Ca.

When the container has been used for a long time, the lower surface of the shoulder wall of the inner plug Ba has only a cut groove 52 which is piercable and has no cut portion such as a cut. A high sealing effect is maintained even if the pressure contact with the top surface of the mouthpiece portion Aa of the container is maintained and the interference between the mouthpiece portion Aa of the container and the inner cylinder Ba inner cylinder 43 is reduced.

When the container is discarded after the use of the content liquid, when the knob 51 of the outer cylinder 42 of the inner plug Ba is pulled, the outer cylinder 42 is cut along the cutting groove 52 provided on the lower surface of the shoulder wall 44. And the inner plug Ba can be easily removed.

Next, a third embodiment will be described. In the present embodiment, the cap Ca of the second embodiment is changed, and the following description will focus on the differences. Since it is the same as the inner plug Ba except that the flange 78 is protruded from the outer cylinder 75 and the step is not provided at the upper end of the outer periphery, detailed description is omitted.

In FIG. 12, Ab is the mouthpiece of the container, B
b is an inner plug, Cb is a cap. A fitting ridge 70 and a holding ridge 71 are provided on the outer periphery of the barrel Ab. The inner stopper Bb is fitted to the container mouth tube Ab. Fitting tube 72
And a screw-in tube 74 in which an injection tube 73 is connected, and the fitting tube 72 includes an outer tube 75, an inner tube 76, and a shoulder wall 77. A flange 78 protrudes from an outer peripheral end of the outer cylinder 75.

As shown in FIG. 12, the cap Cb has a top wall 80, a side cylinder wall 81, and a cover cylinder 82 provided below the side cylinder wall 81. At the lower end of the side tube wall 81, a shoulder wall 83 which extends in a flange shape is continuously provided, and a side tube 84 is vertically provided so as to reach the flange 78 from the peripheral edge of the shoulder wall 83. The shoulder wall 83 and the side tube 84 constitute a cover tube 82 for the fitting tube 72 of the inner plug Bb.

In this embodiment, the same function and effect as those of the second embodiment can be obtained. Further, since the inner plug Bb is fitted by the covering cylinder 82 of the cap Cb, dust in the air can be obtained. Can be prevented from entering the fitting tube portion of the inner plug.

Next, a fourth embodiment will be described with reference to the drawings. Although the first embodiment relates to a dispensing container capable of separating the inner plug, the configuration of the fitting cylinder of the mouthpiece and the inner plug is changed to a normal liquid dispensing container that does not separate the inner plug. Applicable.

In FIG. 13, Ac is the mouthpiece of the container, B
c is an inner plug, and Cc is a cap. An enlarged diameter fitting portion 90 is formed on the upper portion of the container mouth cylinder portion Ac, and an engagement ridge 91 and a holding ridge 92 are provided on the outer periphery thereof.

The fitting cylinder 93 of the inner plug Bc comprises an outer cylinder 94 and an inner cylinder 95, and a middle cylinder 96 and a shoulder wall 97.
Is fitted to the enlarged diameter fitting portion 90 by the inner cylinder 95 and the middle cylinder 96. When the inner plug Bc is fitted, the engagement ridge 98 of the outer cylinder 94 engages with the lower side of the engagement ridge 91,
A high sealing effect can be obtained by the inner lower surface 97a of the shoulder wall 97 being pressed against the wide top surface of the enlarged diameter fitting portion 90 and the middle cylinder 96 fitted to the outer periphery of the enlarged diameter fitting portion 90. .

[0044]

Since the present invention is configured as described above, it has the following effects. Since the joint surface between the lower surface of the shoulder wall of the inner plug and the upper surface of the container mouthpiece is widened, the sealing effect between the container mouthpiece and the inner stopper can be enhanced. Therefore, even if the liquid discharging container is used for a long period of time, a high sealing effect is maintained between the lower surface of the shoulder wall and the container mouth portion, so that liquid leakage due to a reduced interference can be eliminated.

In the case of the shoulder score type inner plug, since no cut is formed in the shoulder wall on the upper surface of the mouthpiece portion, the sealing effect is not reduced, and liquid leakage through the cut portion can be eliminated.
