It is provided with a hexagonal groove 4e provided on the (opposite surface of the top wall 2b) and adaptable to the protrusion 2e. As a result, in a state where the lid 4 is aligned with the base 2, the protrusions 2 e and the grooves 4 e are engaged with each other in the circumferential direction around the axis S 2 of the lid 4, and the lid 4 is rotated. The movement can be prevented. The protrusion 2e and the groove 4e are not limited to the illustrated examples as long as they can be locked to each other in the circumferential direction. For example, the protrusion 2e and the groove 4e may be oval or other polygons (triangle, quadrangle, pentagon, etc.). It may be a regular shape.

  In the middle stopper 1 of this embodiment, when the contents in the container C are to be poured out, the pouring hole of the lid 4 in a posture (see FIG. 1) in which the lid 4 is aligned with the base 2. Perform through 4b. When the container C becomes empty and contents are transferred from another container into the container C, the lid 4 is rotated around the hinge 3 to open the opening 2a of the base 2. Thereby, since the opening part 2a is larger than the extraction hole 4b, the contents can be easily transferred through the opening part 2a.

  Therefore, according to the inner plug 1, the contents can be transferred without removing the inner plug 1 from the opening C 1 of the container C. The inside plug is not soiled and the inside plug is not contaminated.

  Further, when the cap L is tightened into the mouth portion C1 of the container C or when the cap L is loosened and opened, the lid 4 is relative to the base 2 by the rotational force transmitted from the seal member L4 of the cap L. Since the rotation stopper 5 of the inner stopper 1 prevents the rotation of the inner stopper 1, the hinge 3 is formed small assuming that the cap L is attached to the mouth C1 of the container C (that is, r <R However, the lid 4 does not rotate with respect to the base 2 and the breakage of the hinge 3 can be advantageously prevented.

  Further, in the inner plug 1 of this embodiment, the protrusion 2e as the detent 5 and the groove 4e are engaged with each other over the entire circumferential direction, so that an excellent detent effect can be realized.

  Next, another embodiment of the present invention will be described with reference to the drawings.

  In the inner plug 1 according to the second embodiment shown in FIG. 4, the basic configuration of the base 2 and the lid body 4 is substantially the same as that of the first embodiment. Here, the detents 5 are formed on the upper surface of the top wall 2b of the base 2 with two convex portions 2f rising toward the lid body 4 and on the convex portion 2f formed on the lower surface of the top plate 4a of the lid body 4, respectively. It consists of two conforming recesses 4f. Each convex part 2f is arrange | positioned in the position which opposes on both sides of the opening part 2a. In addition, the number of the convex part 2f and the recessed part 4f is not limited to the example of illustration, It is good also as each one or three or more. Although not shown, the configuration of the convex portion 2f and the concave portion 4f may be reversed, that is, the concave portion is provided on the top wall 2b of the base 2, and the convex portion that fits the concave portion is provided on the top plate 4a of the lid 4.

In this embodiment, the base 2 is provided with a slit 6 that extends beyond both ends of the hinge 3 and that partially separates the hinge 3 side of the outer cylindrical portion 2d and the top wall 2b. Further, as shown in FIG. 7, the outer cylinder portion 2d has an outer cylinder portion having at least one end (here, both ends) e1 and e2 of the slit 6 as break starting ends and the lid body 4 as a knob piece. The fracture | rupture scheduled part 7 which cancels | releases the undercut engagement of the outer cylinder part 2d and the opening part C1 of the container C by 2d tearing is formed. More specifically, the planned fracture portion 7 includes vertical fracture planned lines 8 and 9 extending from the ends e1 and e2 of the slit 6 to the lower end of the outer cylinder portion 2d. Here, the longitudinal fracture lines 8 and 9 are formed by grooves whose thickness is thinner on the inner surface of the outer cylinder part 2d than on other parts, but the weakening pieces that can be broken are spaced apart from each other. The longitudinal fracture lines 8 and 9 may be formed by arranging in a grid (not shown).

  In the inner plug 1 of this embodiment, when the inner plug 1 is removed from the container C and discarded or collected, if the lid body 4 in an open posture is gripped as a knob piece and pulled down, When the hinge 3 side of the outer cylinder portion 2d is broken along the longitudinal fracture lines 8 and 9 with the ends e1 and e2 of the slit 6 as break start ends by the operation, the break reaches the lower end of the outer cylinder portion 2d. A portion sandwiched between the vertical fracture planned lines 8 and 9 of the outer cylinder portion 2d is torn off. Thereby, the engagement between the outer cylinder part 2d and the mouth part C1 of the container C is weakened, and then the remaining part of the outer cylinder part 2 remaining in the mouth part C1 of the container C is removed from the mouth part C1 of the container C. The plug can be removed from the container.

  Therefore, according to this embodiment, in addition to the effect of the inner plug 1 of the above-described embodiment, the container C and the inner plug 1 can be easily separated and discarded or recovered after use. Furthermore, the tearing of the outer cylindrical portion 2d can be easily achieved by gripping the lid 4 having a size that is reasonably sized for gripping.

This embodiment is the same as the inner plug 1 according to the fourth embodiment in that the slit 6 is provided in the base 2, but is slightly different in the configuration of the planned fracture portion 7. That is, here, the planned fracture portion 7 has a vertical fracture planned line 8 extending from one end e1 of the slit 6 to the lower end of the outer cylindrical portion 2d, and the other end e2 of the slit 6 as a fracture start end, It consists of a transverse break planned line 10 that extends along the circumferential direction of the outer cylinder part 2d via the front side of the inner plug 1 (opposite the hinge) and terminates before the longitudinal break planned line 8. Here, the planned vertical break line 8 and the planned horizontal break line 10 are formed by grooves whose thickness is thinner than other parts, but the breakable weakening pieces are arranged in a perforated manner at intervals. By doing so, you may form the vertical fracture line 8 and the horizontal fracture line 10 (illustration omitted). In addition, although the groove | channel which forms the longitudinal fracture scheduled line 8 is recessedly provided in the inner surface of an outer cylinder part, and the groove | channel which forms the transverse fracture planned line 10 is recessedly provided in the outer surface of an outer cylinder part, these grooves are You may provide in either the inner surface or outer surface of an outer cylinder part. Moreover, although it is desirable that the lateral fracture planned line 10 is provided more than half a circumference along the circumferential direction of the outer cylinder part 2d, it is not particularly limited.

In removing the inner plug 1 of the embodiment from the container C, first, the lid 4 in the open posture is grasped as a knob piece, and is pulled down downward, and the planned vertical fracture line 8 connected to one end e1 of the slit 6 is formed. The outer cylinder part 2d is broken along. Next, by pulling the lid body 4 in the lateral direction, the lower portion of the outer cylinder portion 2d below the planned horizontal break line 10 is pulled, and the outer cylinder portion 2d is broken along the planned horizontal break line 10, The inner plug 1 can be removed from the container C by pulling up the lid 4 after the rupture reaches the rupture end end 10a (end position of the planned lateral rupture line). In this embodiment, by terminating the planned horizontal fracture line 10 before the planned vertical fracture line 8, even if the outer cylindrical part 2d is fractured, the upper part of the horizontal fracture planned line 10 and the Since the connecting portion 2d ₂ that connects the side portions is formed, unlike the inner plug 1 of the fourth embodiment, the outer cylindrical portion 2d is divided into two when the outer cylindrical portion 2d is completely broken. Therefore, it is possible to remove the inner plug 1 with fewer work steps.

  Although the present invention has been described based on the illustrated examples, the present invention is not limited to the above-described embodiment, and can be appropriately changed within the scope of the claims.
