However, when it is desired to use the liquid contained in the liquid container, a finger, chopstick, or the like inserted or locked in the space S of the pull ring 8A may be pulled up in either the left or right direction in the figure. At this time, the pull rings 8A are attached to both sides of the surface of the sealing wall 6.
Since the bridge is bridged through two connection points 9, it is possible to avoid the application of a large tensile force or bending stress exceeding the allowable stress to only one connection point 9 of the pull ring 8A because the points of action are plural. You can Therefore, in any pulling direction, only a part of the pull ring 8A is not torn apart, the sealing wall 6 is smoothly and easily peeled off from the thin cut portion 7, and the hollow portion of the inner plug body 1 is hollow. The part 2 forms the outlet, and the liquid content in the liquid container can be reliably used. In addition, the space S above the pull ring 8A
Is curved and expanded into a substantially circular shape and spreads, and protrudes upward from the surface of the flange 3. Therefore, it is obvious that a finger, chopsticks, or the like can be inserted and locked in the pull ring 8A very easily.

Next, FIG. 3 shows a third embodiment of the present invention. The inner plug body 1 in this embodiment has a substantially cylindrical shape as shown in FIG. The hollow portion 2 is detachably fitted to the mouth portion of the container, and the hollow portion 2 functions as an outlet for the content liquid. A flange 3 protruding outward in the radial direction is integrally provided around the upper peripheral edge of the inner plug body 1, and a peripheral portion of the flange 3 forms a liquid container between the outer peripheral surface of the inner plug body 1. A hanging piece 4 for sandwiching the mouth portion is integrally formed by bending, and a protrusion 5 for locking the mouth portion of the liquid container is integrally formed in a protruding state at a lower end of an inner peripheral surface of the hanging piece 4. It is installed around. The inner plug body 1 is concealed by a cap (not shown) that is detachably fitted to the mouth of the container.

Further, the sealing wall 6 is made thinner than the thickness of the peripheral wall of the inner plug body 1 so that it can be easily peeled off, and is horizontally closed in an integrated closed state with the inner peripheral surface of the inner plug body 1. It is fitted. A thin cut portion 7 is provided in an annular shape on the peripheral edge of the surface of the sealing wall 6 in order to form an opening outlet portion, and the thin cut portion 7 is peeled off to form an outlet.

Further, the pull ring 8A having flexibility
Is formed from a plate-shaped bridging piece, is shortened as compared with the first embodiment, and is bent in a substantially horizontal character, and both ends thereof are integrally formed on the surface of the sealing wall 6, respectively. It is connected. Therefore, in this embodiment, the amount of upward extension of the pull ring 8A and the space S for insertion / locking are reduced as compared with the first embodiment.

However, when it is desired to use the liquid contained in the liquid container, a finger, chopstick, or the like inserted / locked in the pull ring 8A may be pulled up in either the right or left direction in the figure. At this time, the pull rings 8A are bridged on both sides of the surface of the sealing wall 6 through the two connection points 9, so that the points of action are plural,
It is possible to easily avoid that a large tensile force or bending stress exceeding the allowable stress acts on only one connection point 9 of the pull ring 8A. Therefore, in any pulling direction, only a part of the pull ring 8A is not torn apart, the sealing wall 6 is smoothly and easily peeled off from the thin cut portion 7, and the hollow portion of the inner plug body 1 is hollow. The part 2 forms the outlet, and the liquid content in the liquid container can be reliably used. The above-described various shapes of the pull ring 8A are appropriately selected and used based on the size and shape of the outlet, the inner diameter of the inside plug, and the like.

In the above embodiment, the substantially cylindrical inner plug body 1 is used.
However, the inner plug body 1 having an elliptical shape, a triangular shape, a quadrangular shape, a polygonal shape or the like may be used. In addition, if substantially the same action and effect can be expected, the shape, structure, material, transparency and translucency of the inner plug body 1, the hollow portion 2, the flange 3, the hanging piece 4, the protrusion 5, and the like. It is needless to say that the color may be appropriately selected, modified, changed, or omitted. For example, the hanging piece 4 may be extended, shortened, or curved. Further, the outer peripheral surface of the inner plug body 1 may be formed so as to gradually increase in diameter from the diameter decreasing from the upper side to the lower side. Further, the inner peripheral surface of the inner plug body 1 may be formed such that the diameter gradually increases to the diameter decreases. Further, in the above embodiment, the sealing wall 6 having a substantially circular plane is used, but a substantially elliptical plane is used.
The sealing wall 6 having a triangular shape, a quadrangular shape, a polygonal shape, or the like may be used. Alternatively, the sealing wall 6 or the periphery thereof may be formed into an inclined surface so that a liquid pool is formed on the wall around the sealing wall 6. It may be possible to prevent it from happening. Further, the number of notches, the notch locations, the shape, etc. of the thin cut portion 7 may be changed as appropriate. Further, in the above embodiment, the pull ring 8A
Is shown in the form of a plate or a belt, but the pull ring 8A and the ring 8a may have the same shape, structure, material, transparency or translucency, as long as they have substantially the same effects. Alternatively, the color may be appropriately modified or changed, or the pull ring 8A may be laid sideways or diagonally depending on the shape and structure of the cap that is detachably fitted on the inside plug body 1.
Further, in the above-described embodiment, the pulling ring 8A is bridged on both sides of the surface of the sealing wall 6 through the two connecting points 9, but if the pulling ring 8A has substantially the same action and effect, the Even if the pull ring 8A is provided in a bridge or in another mode other than the bridge via a plurality of connection points 9 such as at three locations and four locations, the same operational effects as those of the above-described embodiment can be obtained. Further, the inner stopper for a liquid container according to the present invention can be widely used for a liquid container for food, a liquid container for cosmetics, detergents, or chemicals. Furthermore, the inner stopper for a liquid container according to the present invention may be appropriately used for a container for containing powdery substances, viscous substances and the like.
