That is, it is not necessary to carry the cord provided with the magnet plug 20 when using the alternative power supply.

In addition, when the AC power supply is used and when the alternative battery is used, it is possible to cope with the attachment and detachment of the connection unit 54, so that it does not hinder the actual use, and the appearance when using the AC power supply and when using the alternative power supply can be clearly seen. Can be distinguished. In addition, a sense of unity with the container body 1 can be obtained from the external appearance, and when the remaining hot water is discarded, the connection unit 54 may be removed, so that the water can be reliably prevented from getting wet. Further, if the magnet plug 20 is attached with the connection unit 54 attached, the AC power supply can be used as it is. As an alternative power supply, a battery may be used instead of the capacitor. The other configuration is the same as that of the above-described reference example, and thus the description is omitted.

Although the above embodiment has been described with respect to a pump-injection type liquid container which is both a water heater and a water heater, the present invention is applicable to other types of pump-infusion type liquid containers. Of course.
