(Instructions) The procedure for placing substances into the container 10A with a lid is explained. As an example, a case in which milk powder as a first substance, water as a second substance and a third substance, and a heating agent as a fourth substance are used will be described. The heating agent is preferably packaged in a water-permeable bag. The heating agent includes powdered aluminum and powdered quicklime, for example. The bag body can be formed of non-woven fabric, Japanese paper, synthetic paper, etc. with a specific unit area weight that allows water to be soaked.

First, as shown in FIG. 4A , the top cover 30 of the cover body 16 is turned downward, and the second opening 27 turns upward to put the second substance 66 into the second receiving part 28 . Next, the female thread 44 is screwed into the male thread 32 until the front end of the outer wall portion 24 contacts the second bottom cover 36, whereby the fixed body 20A is installed on the cover 16 (Fig. 4B). Then, the first substance 68 is put into the first receiving part 26 from the first opening 25 facing upward. Next, the front end of the inner wall portion 22 is inserted into the groove 19, thereby attaching the first bottom cover 18 to the cover body 16 (Fig. 4C). In the above manner, the lid 12 containing the first substance 68 and the second substance 66 is obtained.

With the top cover 30 facing upward, screw the small-diameter male thread 58 into the small-diameter female thread 50, thereby installing the inner container 52 containing the third substance 70 in advance to the lid 12 (Fig. 5). Next, the large-diameter male thread 62 is screwed into the large-diameter female thread 46, thereby attaching the container 54 in which the fourth substance 72 is previously placed to the lid 12. In the above manner, a lidded container 10A ( FIG. 6 ) is obtained in which the first substance 68 , the second substance 66 , the third substance 70 , and the fourth substance 72 are stored in separate states. In other words, a container-packed food and drink containing the food and drink (the first substance 68 and the third substance 70) in the container 10A with a lid is obtained.

Next, the procedure of transferring the first substance 68 and the second substance 66 contained in the lid 12 into the container 14 will be described. First, as shown in FIG. 7 , the cover 16 is rotated in the opening direction. The cover 16 moves upward in the axial direction by rotation. When the edge of one side surface of the first bottom cover 18 comes into contact with the contact portion 34 , the first bottom cover 18 is detached from the front end of the inner wall portion 22 and falls into the inner container 52 . The first substance 68 in the first receiving part 26 falls into the inner container 52 together with the first bottom cover 18 . The first substance 68 that falls into the inner container 52 , that is, the milk powder, is mixed into the third substance 70 that is contained in the inner container 52 , that is, water. The first bottom lid 18 dropped into the inner container 52 functions as a stirring element when the lidded container 10A is shaken, and the first substance 68 and the third substance 70 are mixed more effectively.

Furthermore, while the cylindrical sealing portion 48 is in contact with the outer peripheral surface of the inner wall portion 22 , the space between the second receiving portion 28 and the first receiving portion 26 is sealed, so the second substance 66 will not escape from the first receiving portion 26 The fluid flows into the inner container 52 .

As the cover 16 moves upward in the axial direction, the front end of the outer wall portion 24 moves away from the second bottom cover 36 , and a gap is formed between the front end and the surface of the second bottom cover 36 . The second substance 66 in the second receiving part 28 flows out from the gap and flows into the space between the outer container 54 and the inner container 52 through the communication passage 38 (arrow in FIG. 7 ). The second substance 66 flowing between the outer container 54 and the inner container 52 reaches the fourth substance 72 contained in the outer container 54 . Water as the second substance 66 penetrates the bag body and comes into contact with the heating agent. The heating agent produces an exothermic reaction by adding water. By the exothermic reaction, the first mixture 71 formed by mixing the first substance 68 and the third substance 70 in the inner container 52 is heated.

After the exothermic reaction is completed, the cover 16 is removed from the fixed body 20A (Fig. 8), and then the outer container 54 and the inner container 52 are removed from the fixed body 20A (Fig. 9). In the above manner, milk 71 heated to a specific temperature is obtained. On the inner container 52, another cover with a drinking mouth (such as an artificial pacifier) can also be reinstalled on its opening.

(function and effect) By having the first receiving part 26 and the second receiving part 28, the lid 12 can separately store the first substance 68 and the second substance 66. The lid 12 rotates the lid body 16 in the opening direction, so that the first bottom lid 18 can be detached from the inner wall portion 22, and the seal between the outer wall portion 24 and the second bottom lid 36 can be released, so that the first substance 68 can be separated from the second bottom lid 36. 2The substance 66 is transferred into the container 14. That is, the user can transfer the first substance 68 and the second substance 66 into the container 14 by rotating the lid 16 in the opening direction once. In the case of this embodiment, the first storage portion 26 is sealed by the first bottom cover 18, so the first substance 68 can be transferred from the cover 12 to the inner container 52 without being exposed to the outside atmosphere.

In the case of this embodiment, by providing the inner container 52 and the outer container 54, it is possible to obtain the first mixture including the first substance 68 in the first container 26 and the third substance 70 in the inner container 52, and the second The second mixture of the second substance 66 in the receiving part 28 and the fourth substance 72 in the outer container 54.

By using a heating agent as the fourth substance 72, the second mixture in the inner container 52 can be heated. Therefore, the first substance 68, that is, milk powder, and the third substance 70, that is, water, can be mixed without being exposed to the outside atmosphere, and then heated to a specific temperature. Therefore, a product heated to a specific temperature can be produced in a hygienic and simple process. The temperature of milk is 71.

(Example of variation) The present invention is not limited to the above-described embodiment, and can be appropriately modified within the scope of the spirit of the present invention.

In the above embodiment, the case where the cover 16 is removed has been described, but the present invention is not limited to this. For example, by using a cover body with a drinking spout as the top cover 30 , the cover body and the fixing body 20A can be kept installed in the container 14 for use. In this case, it is preferable to have a casing covering the cover.

In the above embodiment, the case where the heating agent is used as the fourth substance 72 has been described, but the present invention is not limited to this. For example, by appropriately selecting the second substance 66 and the fourth substance 72, it is possible to obtain a food (second mixture) in which the second substance 66 and the fourth substance 72 are mixed, and further, it is possible to obtain a mixture of the first mixture and the fourth substance 72. 2 Foods made from mixtures (third mixture).

In the case of the above embodiment, the case where the first substance 68 is transferred to the inner container 52 and the second substance 66 is transferred to the outer container 54 are substantially the same has been described. However, the present invention does not Limited to this. For example, the second substance 66 may be transferred into the outer container 54 before the first substance 68 . In this case, by making the distance between the first bottom cover 18 and the contact portion 34 longer, the first substance 68 can be transferred to the inner container 52 at a earlier time than the second substance 66 is transferred to the outer container 54 . It's late inside.

In the case of the above embodiment, the container 14 has the inner container 52 and the outer container 54. However, the present invention is not limited to this. For example, the lidded container 10B shown in FIG. 10 omits the inner container 52 . That is, the container of the lidded container 10B is only the outer container 54 . The fixed body 20B omits the second inner cylinder portion. In the container with lid 10B, the first substance 68 and the second substance 66 are accommodated in the lid 12 , and the third substance 70 is accommodated in the outer container 54 . The cover 16 has a third sealing surface 74 at a position where the base end of the outer cylinder 40 contacts. The third sealing surface 74 is an annular surface parallel to the radial direction of the cover 16 . The outer container 54 is sealed by the third sealing surface 74 and the second sealing surface 60 .

By rotating the cover body 16 in the opening direction, the first bottom cover 18 is detached from the front end of the inner wall portion 22 (Fig. 11). The first substance 68 in the first receiving part 26 falls into the outer container 54 together with the first bottom cover 18 . At the same time, as the cover 16 moves upward in the axial direction, the second substance 66 in the second receiving part 28 flows out from the gap between the front end of the outer wall part 24 and the surface of the second bottom cover 36 and flows in through the communication passage 38 Inside the container (arrow in Figure 11). In this way, the food (the fourth mixture) in which the first substance 68, the second substance 66, and the third substance 70 are mixed can be obtained in the outer container 54.

In the case of the above embodiment, the case where the first sealing surface 56, the second sealing surface 60, and the third sealing surface 74 are annular surfaces parallel to the radial direction has been described, but the present invention is not limited to this. It may be an annular surface inclined relative to the axial direction.
