As a result, the breaking member 34 is prevented from being accidentally moved upwardly from the installed position shown in FIG. In the illustrated example, the breaking member 3
Attached to the upper end of 4 is a relatively large diameter enlarged head member 48 which may be formed from any suitable synthetic resin material such as polyethylene or polypropylene. A circular recess 50 is formed on the upper surface of the breaking member 34, while a circular projection 52 is formed on the lower surface of the enlarged head member 48, and by press-fitting the circular projection 52 into the circular recess 50, Breaking member 3
4 is attached with an enlarged head member 48.

As described above, the breakable member 3 is inserted into the recessed recess 12.
4 and the annular stop member 46 are disposed, the closing member 54 is detachably attached to the upper surface of the lid body 4, thus closing the upper surface of the recess 12.
The closing member 54 can be formed from a single layer of aluminum foil or a laminate of aluminum foil laminated with paper or the like, and is provided on the top surface of the lid body 4, more specifically on the top surface of the annular top wall 28 of the outer member 8. It is preferable to releasably join them using a suitable adhesive.
As clearly shown in FIG. 2, the closing member 54 has a circular shape having a size sufficient to close the upper surface of the recessed recess 12, and extends radially outwardly from its periphery to the periphery of the annular top wall 28. A grip portion 56 that protrudes beyond is integrally formed. Closing member 5
By closing the upper surface of the recessed recess 12 with 4, dust etc. are reliably prevented from entering into the recessed recess 12, and the second substance M accommodated in the recessed recess 12 is prevented from being pilfered. characteristics are ensured.

The lid 2 as described above may include, for example, a container 60 having a neck portion 58 in the form shown in FIG.
That is, it can be used in combination with a glass container 60 that is widely used as a beverage container.
Referring to FIG. 3, a male thread 62 and an annular jaw portion 64 located below the male thread 62 are formed on the outer peripheral surface of the approximately cylindrical mouth and neck portion 58.

After storing the first substance (not shown) in the container 60, the lid body 4 is attached to the neck and neck portion 58, and the neck and neck portion 58 is thus closed. mouth and neck 5
8, the second substance M is accommodated in the recessed recess 12 of the lid body 4, and the breaking member 34, the annular stop member 46, and the closing member 54 are attached to the lid body 4. Alternatively, after the lid body 4 is attached to the mouth and neck part 58, the second substance M is accommodated in the recessed recess 12 of the lid body 4, and the breaking member 3 is attached to the lid body 4.

As shown in the figure, the lid main body 4 is fitted onto the mouth and neck part 58, the bottomed hanging wall 14 of the inner member 6, and therefore the recessed recess 12 are positioned within the mouth and neck part 58, and the outer member 8
The cylindrical skirt wall 30 of is positioned on the outside of the mouth and neck portion 58, and the annular top wall 10 of the inner member 6 and the annular top wall 28 of the outer member 8 are pressed against the upper end surface of the mouth and neck portion 58. Next, the neck portion 5 is attached to the main portion 33 of the cylindrical skirt wall 30 of the outer member 8.
A female thread 66 is formed along the male thread 62 of No. 8, and the lower end of the pilfer-proof hem 35 is bent radially inward to engage the annular jaw 64 of the neck portion 58. When the lid main body 4 is attached to the mouth and neck part 58 in this manner, the mouth and neck part 58 is sufficiently and reliably sealed, especially because the annular upper wall 10 of the inner member 6 is pressed against the upper end surface of the mouth and neck part 58.

In order to use the second substance M contained in the recessed part 12 of the lid 2 by mixing it with the first substance (not shown) contained in the container 60, the following operation is performed. All you have to do is carry out the following. First, the gripping portion 56 of the closing member 54 in the lid 2 is grasped and pulled upward, thereby removing the closing member 54 from the upper surface of the lid body 4 and releasing the upper surface of the recessed recess 12.
Next, the enlarged head 48 attached to the upper end of the breaking member 34 is pressed to lower the breaking member 34. In this way, the hanging part 38 of the breaking member 34 acts on the bottom part 22 of the bottomed hanging wall 14 defining the recessed recess 12, causing it to break. Therefore, the second substance M accommodated in the submerged recess 12 flows down into the container 60 through the broken bottom 22, and the first substance M accommodated in the container 60 (not shown) flows down into the container 60 through the broken bottom 22. ). Downward movement of the breaking member 34 is limited by the abutment of the enlarged head member 48 against the annular stop member 46, as shown in phantom in FIG. After that, grip the lid body 4, more specifically, the outer member 8, and move it in a predetermined direction, that is, in the third direction.
Rotate counterclockwise when viewed from above in the figure. In this way, the female thread 6 formed in the main portion 33 of the cylindrical skirt wall 30 of the outer member 8
6 is moved along the male thread 62 of the neck portion 58, the outer member 8 tends to move upward with rotation. However, the pilfer-proof hem 35 of the cylindrical skirt wall 30
The annular weakened line 3 cannot move upward because it is locked to the annular jaw 64 of the
1. More specifically, a considerable stress acts on the bridge portion 29 (see FIGS. 1 and 2), causing the bridge portion 29 to break, and the pilfer-proof hem portion 35 to be attached to the main portion of the cylindrical skirt wall 30. It is separated from section 33. After that, the entire lid 2 except the pilf-proof hem 35 can freely move upward as it rotates, and the lid 2 is separated from the neck part 58 with the pilf-proof hem 35 remaining. Ru. If desired, one or more axial lines of weakening (such The weakened line may be a so-called score or perforation), and by breaking this axial weakened line, the pilfer-proof hem 35 is opened from an endless annular shape to an edged band shape, and is separated from the annular jaw 64. In this way, the pill-proof hem 35 can also be removed without being left in the mouth and neck area 58.
When the lid 2 is removed from the mouth and neck part 58, the mouth and neck part 58
is opened, and the first substance mixed with the second substance M can therefore be discharged from the container 60.
