(how to use)
A procedure for putting a substance into the capped container 10A will be described. As an example, a case of applying powdered milk as the first substance, water as the second and third substances, and a heating agent as the fourth substance will be described. The heating agent is preferably packed in a water-permeable bag. The heating agent is made of powdered aluminum and powdered quicklime, for example. The bag body can be formed of a non-woven fabric, Japanese paper, synthetic paper, etc. having a predetermined basis weight permeable with water.

First, as shown in FIG. 4A, the canopy 30 of the lid 16 is directed downward, and the second substance 66 is put into the second container 28 through the second opening 27 directed upward. Next, the fixed body 20A is attached to the lid body 16 by screwing the female thread 44 into the male thread 32 until the tip of the outer wall portion 24 contacts the second bottom lid 36 (FIG. 4B). Subsequently, the first substance 68 is put into the first containing portion 26 through the upward first opening 25 . Next, the first bottom lid 18 is attached to the lid body 16 by fitting the tip of the inner wall portion 22 into the groove 19 (FIG. 4C). As described above, the cap 12 containing the first substance 68 and the second substance 66 is obtained.

By turning the canopy 30 upward and screwing the small diameter male screw 58 into the small diameter female screw 50, the inner container 52 containing the third substance 70 is attached to the cap 12 (FIG. 5). Next, by screwing the large-diameter male thread 62 into the large-diameter female thread 46, the outer container 54 containing the fourth substance 72 in advance is attached to the cap 12. As shown in FIG. As described above, the capped container 10A in which the first substance 68, the second substance 66, the third substance 70, and the fourth substance 72 are separately accommodated is obtained (FIG. 6). In other words, a container-packed food or drink is obtained in which the food or drink (the first substance 68 and the third substance 70) is contained in the capped container 10A.

Next, a procedure for transferring the first substance 68 and the second substance 66 accommodated in the cap 12 into the container 14 will be described. First, as shown in FIG. 7, the lid 16 is rotated in the opening direction. The lid body 16 moves upward in the axial direction by rotation. When the edge of one side surface of the first bottom lid 18 contacts the contact portion 34 , the first bottom lid 18 drops from the tip of the inner wall portion 22 and falls into the inner container 52 . The first substance 68 in the first containing portion 26 drops into the inner container 52 together with the first bottom lid 18 . Powdered milk, which is the first substance 68 that has fallen into the inner container 52 , is mixed with water, which is the third substance 70 contained in the inner container 52 . The first bottom lid 18 that has fallen into the inner container 52 functions as a stirrer and mixes the first substance 68 and the third substance 70 more efficiently when the capped container 10A is shaken.

Note that while the cylindrical seal portion 48 is in contact with the outer peripheral surface of the inner wall portion 22, the space between the second containing portion 28 and the first containing portion 26 is sealed. There is no flow from inside the portion 26 into the inner container 52 .

By moving the lid body 16 upward in the axial direction, the tip of the outer wall portion 24 is separated from the second bottom lid 36 to form a gap between the tip and the surface of the second bottom lid 36 . The second substance 66 in the second containing portion 28 flows out through the gap and flows between the outer container 54 and the inner container 52 through the communication passage 38 (arrow in FIG. 7). The second substance 66 that has flowed between the outer container 54 and the inner container 52 reaches the fourth substance 72 contained in the outer container 54 . Water, which is the second substance 66, permeates the bag and contacts the heating agent. The heating agent reacts exothermically with the addition of water. The exothermic reaction heats milk 71 , a first mixture of first substance 68 and third substance 70 in inner container 52 .

After the exothermic reaction is completed, the lid 16 is removed from the fixed body 20A (FIG. 8), and the outer container 54 and the inner container 52 are removed from the fixed body 20A (FIG. 9). Milk 71 heated to a predetermined temperature is obtained as described above. The opening of the inner container 52 may be reattached with another lid having a drinking mouth (for example, an artificial teat).

(Action and effect)
The cap 12 can contain the first substance 68 and the second substance 66 separately by having the first containing portion 26 and the second containing portion 28 . By rotating the lid body 16 in the opening direction, the cap 12 removes the first bottom lid 18 from the inner wall portion 22 , releases the seal between the outer wall portion 24 and the second bottom lid 36 , and releases the first substance 68 . A second substance 66 can be transferred into the container 14 . That is, the user can transfer the first substance 68 and the second substance 66 into the container 14 with one operation of rotating the lid 16 in the opening direction. In the case of this embodiment, since the first containing portion 26 is sealed by the first bottom lid 18, the first substance 68 can be transferred from the cap 12 to the inner container 52 without exposing it to the outside air.

In the case of this embodiment, by providing the inner container 52 and the outer container 54, the first mixture composed of the first substance 68 in the first container 26 and the third substance 70 in the inner container 52 and the second container A second mixture of second substance 66 in section 28 and fourth substance 72 in outer container 54 can be obtained.

The second mixture in the inner container 52 can be heated by applying a heating agent as the fourth substance 72 . Therefore, powdered milk, which is the first substance 68, can be mixed with water, which is the third substance 70, without being exposed to the outside air, and further heated to a predetermined temperature. can be made.
