It is made to contact | abut or adjoin to the lower surface of this. The cutting member 10 is advanced to the upper end of the drooping wall lower portion 72 of the outer lid 8, and an annular protrusion 94 formed on the outer peripheral surface of the peripheral edge portion 90 is formed at the upper end portion of the inner peripheral surface of the drooping wall lower portion 72. The annular protrusion 74 is elastically moved over and engaged therewith, and is thus held in the position shown in FIG. The auxiliary member 12 is held at the position shown in FIG. The arc 102 of the cutting member 10, i.e. the second cutting means, is located opposite the breakable seal member 106 of the auxiliary member 12.
[0021]
The outer lid 8 on which the auxiliary container 12 and the cutting member 10 are attached is attached to the container 112 by being lowered from above to the position illustrated in FIG. 1 to cover the lid body 4 and the additional member 6 attached thereto. As clearly shown in FIG. 1, the annular ridge 80 formed at the lower end portion of the inner peripheral surface of the hanging wall lower portion 72 is elastically over the bulging portion 122 of the container 112 and is engaged with the annular groove portion 124. This prevents the outer lid 8 from rising relative to the container 112. Further, the lower end of the hanging wall lower portion 72 is brought into contact with the shoulder 126 of the container 112, thus preventing the outer lid 8 from further descending with respect to the container 112. Each of the plurality of locking pieces 88 formed on the inner peripheral surface of the hanging wall lower portion 72 is positioned between the plurality of protruding pieces 58 formed on the outer peripheral surface of the cylindrical wall 52 of the additional member 6. This prevents the outer lid 8 from rotating relative to the additional member 6. When the outer lid 8 is lowered to the position shown in FIG. 1, the lower annular protrusion 78 formed on the inner peripheral surface of the hanging wall lower portion 72 is formed at the lower end portion of the protruding piece 58 of the additional member 6. The latching protrusion 60 is elastically overcome and positioned below it. When the outer lid 8 is mounted at a required position, the cylindrical portion 100 of the cutting member 10, that is, the first cutting means is applied to the top wall 14 of the lid body 4, more specifically, to the settling portion 40 formed at the center portion thereof. Located opposite to each other.

The description will be continued with reference to FIG. 1. When the contents contained in the container 112 are consumed, the gripping piece 86 attached to the hanging wall 66 of the outer lid 8 is gripped and pulled. The direction breakable line 82 is broken, and the portion below the circumferential breakable line 82 is removed. Thereafter, the outer lid 8 is pressed downward and lowered to the position shown in FIG. At the time of the lowering, first, the cylindrical portion 100 of the cutting member 10 that is lowered along with the outer lid 8, that is, the first cutting means, is the settling portion 40 formed on the top wall 14 of the lid body 4. It enters into the inside and acts on the breakable line 48 formed in the bottom wall portion 44, leaving a part (the portion located at the right end in FIG. 8) to break, and thus flowing into the bottom wall portion 44. Create an entrance. When the cutting member 10 is further lowered, the lower surface of the annular plate portion 96 of the cutting member 10 comes into contact with the upper surface of the annular wall 50 of the additional member 6, thereby further lowering the cutting main portion 92 of the cutting member 10. Be blocked. Therefore, when the outer lid 8 is further lowered, stress is generated in the bridging portion 98 existing between the peripheral edge portion 90 and the cutting main portion 92 in the cutting member 10, and the bridging portion 98 is broken, so that the cutting member 10 is raised relative to the peripheral portion 90 and the outer lid 8 of the cutting member 10, and as shown in FIG. 8, the arc-shaped portion disposed in the cutting main portion 92. 102, that is, the second cutting means acts on the breakable seal member 106 of the auxiliary container 12 to break the breakable seal member 106 in an arc shape. Thus, the liquid auxiliary substance contained in the auxiliary container 12 flows down through the broken portion of the breakable seal member 106, passes through the cylindrical portion 100 of the cutting member 10, and further, the top wall 14 of the lid body 4. It flows into the container 112 through the inflow port formed in the bottom wall portion 44 of the settling portion 40, and is mixed into the substance accommodated in the container 112. If desired, in order to reliably avoid the liquid auxiliary substance flowing down from the auxiliary container 12 from staying on the upper surface of the annular plate portion 96 of the cutting member 10, at least inside the arcuate portion 102 of the annular plate portion 96. It is also possible to make the portion have an inverted truncated cone shape that is inclined downward inward in the radial direction. When the outer lid 8 is lowered to the position shown in FIG. 8, the upper annular ridge 76 formed on the inner peripheral surface of the hanging wall lower portion 72 of the outer lid 8 protrudes from the additional member 6. The locking projection 60 formed at the lower end of the piece 58 is elastically overcome and positioned below the locking projection 60.
[0023]
After the liquid auxiliary substance contained in the auxiliary container 12 is mixed with the substance in the container 112 as described above, the outer lid 8 is gripped and opened in the open direction, that is, as viewed from above in FIG. Rotate clockwise. When the outer lid 8 is rotated in the opening direction, the additional member 6 and the lid body 4 are also rotated in the opening direction. When the lid main body 4 is rotated in the opening direction, the tamper evidence skirt 26 of the lid main body 4 has locking means 32 formed on the inner peripheral surface thereof, and the engagement means 32 formed on the mouth neck 114 of the container 112. Ascending is prevented because it is locked to the stop jaw 118, but the other parts of the lid body 4 are unscrewed from the male thread 116 of the mouth-and-neck part 114 and the female thread 30 of the lid body 4 As it is done. Accordingly, the circumferentially breakable line 22 formed on the skirt wall 16 is broken, and the tamper evidence skirt portion 26 is separated from the main portion 24 of the skirt wall 16. Thereafter, as shown in FIG. 9, the container lid 2 is lifted with the rotation in the opening direction, leaving the tamper-evidence skirt portion 26 of the lid body 4, and detached from the mouth-and-neck portion 114. Part 114 is opened. The axial movement of the additional member 6 with respect to the lid body 4 is prevented by the engagement of the annular ridge 46 and the annular ridge 62, and the axial movement of the outer lid 8 with respect to the additional member 6 is prevented by the locking protrusion 60 and the upper annular ridge. Blocked by engagement with 76.
