On the outer peripheral surface of the lower cylinder 4, a concave groove 8 into which a knob 14 of the inner plug C described later is fitted is provided, and a convex portion 9 is provided at the bottom of the concave groove 8.
The bottom of the concave groove 8 is formed deeper than the bottom of the screw groove of the screw part 5 so that the screwing of the lid B is not hindered when the knob 14 is accommodated.

As shown in FIGS. 2 and 3, the inner plug C includes a top wall 10 that forms the top, an inner cylinder 11 that is airtightly fitted to the inner peripheral surface of the mouth 1 of the container A, and the mouth 1 of the container A. The outer cylinder 12 is fitted to the outer periphery of the outer cylinder 12 and the knob 14 is connected to the lower end of the outer cylinder 12 via a hinge 13.
The top wall 10 includes a crest 16 that opens the spout 15 at the top, and a skirt 17 that extends horizontally from the lower end of the crest 16, and the inner cylinder 11 is suspended from the bottom of the skirt 17. An outer cylinder 12 is suspended from the outer peripheral edge of the portion 17.

An engagement protrusion 20 that engages with the fitting protrusion 6 of the container A is provided at the lower end of the inner periphery of the outer cylinder 12, and the outer peripheral surface of the outer cylinder 12 has a circular arc formed by the outer peripheral surface in plan view. A flat surface portion 21 having a string as a string is formed in a vertical direction, and a knob portion 14 is integrally provided in a flat plate shape at a lower end thereof via a thin hinge portion 13.
The hinge portion 13 and the knob portion 14 extend in the horizontal direction from the lower end of the outer cylinder 12 in the middle plug C at the time of molding.
The knob 14 is provided with a fitting hole 22 that fits into the convex part 9 at the bottom of the groove 8 in the vicinity of the center, and a lateral rib 23 for facilitating the picking with a finger on the tip side from the fitting hole 22. Is provided.

In the present embodiment, the hinge portion 13 is continuously provided at the lower end portion of the outer cylinder 12, but is not necessarily the lower end portion. For example, the hinge portion 13 is continuously provided in the middle or upper portion of the flat surface portion 21 as necessary. Can be changed.
In the present embodiment, the hinge portion 13 and the knob portion 14 have the same width. However, the hinge portion 13 may be narrower than that of the knob portion 14, and the flat surface portion 21 has at least a hinge width. The width may be 13 or more.

As described above, when the engaging protrusion 20 is not formed at a portion where the hinge portion 13 is continuously provided, that is, a portion corresponding to the flat surface portion 21, the knob 14 is continuously provided when the knob 14 is pulled. Since it is not engaged with the fitting protrusion 6 in the vicinity, the outer cylinder 12 is easily deformed and further easily detached from the mouth 1 of the container A.
Instead of the engaging protrusion 20, a notch may be provided in the fitting protrusion 6 of the container A corresponding to the part for the same purpose.

Next, usage modes and operational effects of this embodiment will be described.
First, in order to attach the inner stopper C to the container A, the circumferential positions of the knob 14 of the inner stopper C and the concave groove 8 of the container A are matched, and the fitting groove between the inner cylinder 11 and the outer cylinder 12 is aligned. The upper tube 2 of the mouth portion 1 is applied to and pressed from above.
With the pressing, the inner plug C is lowered, and the outer cylinder 12 is slightly deformed, and the engaging protrusion 20 gets over the fitting protrusion 6 and is fitted into the annular groove 7 of the mouth portion 1.

The knob portion 14 extending horizontally from the lower end of the outer cylinder 12 of the inner plug C is bent downward by the thin hinge portion 13, and the fitting hole 22 is fitted to the convex portion 9 of the groove 8.
The concave groove 8 is formed to such a depth that the surface of the knob portion 14 does not become higher than the screw thread portion of the lid body screwed into the screw portion 5 when the knob portion 14 is accommodated.
The fitting hole 22 of the knob portion 14 is press-fitted into the convex portion 9 to such an extent that a slight interference fit is achieved, so that the knob portion 14 does not easily come off the convex portion 9 and jump out of the concave groove 8. .
Therefore, when the lid B is screwed to the screw portion 5 and attached to the mouth portion 1, the knob portion 14 of the inner plug C is securely accommodated in the concave groove 8, and therefore becomes an obstacle when screwing. There is nothing, and the knob 14 is not damaged even if the lid B is repeatedly attached and detached.

Thereafter, when removing the inner plug C, if the finger is applied to the tip of the knob part 14 and pulled outward, the fitting hole 22 is removed from the convex part 9, and the knob part 14 is bent upward at the hinge part 13 and pulled up. While the outer cylinder 12 is slightly deformed, the engagement of the engagement protrusion 20 with the fitting protrusion 6 is released, and the inner plug C can be removed from the mouth 1.
At this time, since the flat surface portion 21 is formed on the outer peripheral surface of the outer cylinder 12 and the flat plate-like knob portion 14 is continuously provided at the lower end via the hinge portion 13, the flat plate-like knob portion 14 is disposed outward. Can be easily bent and deformed, and can be easily deformed by the hinge portion 13, so that the knob portion 14 can be easily pulled out from the groove 8 and the thickness of the outer cylinder 12 corresponding to the flat surface portion 21. Is relatively small, it is easy to deform and can be easily removed.

  Moreover, since the knob | pick part 14 and the hinge part 13 are shape | molded in the shape where the knob | pick part 14 and the hinge part 13 extended horizontally from the lower end of the outer cylinder 12, the restoring force which always tries to return to a horizontal direction acts on the knob | pick part 14, If the fitting between the fitting hole 22 and the convex portion 9 is released, the knob portion 14 rises autonomously and comes off the concave groove 8 and is more easily pulled out.

In this embodiment, the threaded portion 5 is employed as the engaging means for attaching the lid B to the container A. However, the threaded portion 5 is not necessarily a screw, and other engaging means such as a hook-shaped engaging portion are used. There may be.
Further, in this embodiment, a container is used by providing a spout 15 in the inner plug C and opening and closing the lid B that seals the spout 15, but the inner plug C has a spout. The member is not limited to a lid, and the member that is screwed into the screw portion 5 and attached to the mouth portion 1 is not limited to the lid.
As shown in FIG. 5, the inner plug C may be removed and the injection pump D may be attached, and the container with an inner plug of the present invention can be used in various forms as required.

Next, a second embodiment in which the configuration of the knob 14 of the inner plug C is changed will be described.
Hereinafter, the same reference numerals are used for the same components as those in the first embodiment, and the differences from the first embodiment will be mainly described.

As shown in FIG. 4, when the knob portion 14 is fitted into the concave groove 8 on both sides of the upper surface and the lid body is screwed to the screw portion 5, Longitudinal ribs 24 are provided that protrude to a height that substantially coincides with the threads of the body.
The knob 14 is provided with the vertical rib 24 so that when the lid B is screwed to the screw portion 5, the screw head of the lid B comes into contact with the surface of the vertical rib 24 and is securely accommodated in the concave groove 8. Therefore, it is possible to prevent the knob portion 14 from being lifted from the groove 8 and being bitten by the screw portion 5.

The vertical ribs 24 may be provided over the entire side portions up to the tip of the knob 14, but in order to facilitate bending deformation of the knob 14 and make it easy to pinch, the knob 24 as in this embodiment shown in FIG. 4 is used. It is better to extend from the part where the part 14 is connected to the hinge part 13 to the vicinity of the center, that is, the vicinity of the fitting hole 22.
The present embodiment is the same as the first embodiment in other configurations, and the operational effects other than the operational effects of the vertical ribs 24 are the same as those of the first embodiment.

The container with an inner plug of the present invention is provided with a knob portion that can be easily pulled out on the inner plug to be attached to the mouth portion, so that the inner plug can be easily removed. It can be used for recycling containers and the like.
In addition, since the knob portion is securely accommodated in the concave groove of the mouth portion of the container, it does not get in the way when the lid body is engaged with the mouth portion, and may be damaged by the engagement of the lid body. Therefore, the container can be suitably used for a container in which the lid is repeatedly attached and detached, or the inner plug is removed during use and another dispensing tool such as an injection pump is attached.
