[0001]

[Industrial applications]

 The present invention relates to a portable heat insulation container provided with a heating means.

[0002]

[Prior art]

 Conventionally, as a heat insulating container, there is a double structure container in which an outer body and an inner body are bonded to each other via a vacuum heat insulating layer, and it is generally known as a thermos bottle. This container has an excellent heat retaining function, and is widely used as a container for hot liquid drinks, for example, and for household use.

[0003]

[Problems to be solved by the device]

 Although the above-mentioned conventional thermos container known as a thermos container has an excellent thermal insulation function, it is unavoidable that the temperature of the contents drops with the passage of time. For this reason, for example, if a hot liquid drink is placed for several hours and the temperature of the liquid drink drops during drinking, the liquid should be transferred to another container and heated to make it hot for drinking. This is often done in households, etc. that have heating equipment around them, put it in a portable heat-insulating container, and heat it when drinking outdoors without any heating equipment. This is impossible, and we have to drink liquid drinks that have become cold.

In view of the above points, the present invention provides a portable heat insulating container which is capable of holding heat for a long time by providing a heating means in the container.

[0005]

[Means for Solving the Problems]

 In order to achieve the above object, the present invention provides a heat-insulating container body provided with a heat insulating means with a heating element for generating heat to heat the contents in the container body. The storage battery is made detachable.

[0006]

[Action]

 According to the present invention, by attaching the storage battery to the heat insulation container body, the heating element provided in the container body heats up and the contents in the container body are heated. The natural temperature drop of the contents in the container body is offset, and the temperature of the contents in the container body is maintained for a long time at a temperature close to the temperature when the contents are put in the container body.

[0007]

【Example】

 Hereinafter, the present invention will be described in detail with reference to the embodiments shown in the drawings. FIG. 1 is a sectional view showing an embodiment of the present invention. In FIG. 1, reference numeral 1 is a heat retaining container body provided with a heat insulating means. The container body 1 has a double structure in which an outer body 2 and an inner body 3 are joined together via a vacuum heat insulating layer 4. A bottom portion 5 of the inner body 3 of the container body 1 is curved inward, and a film-shaped heating element 6 is attached to the outer surface of the curved bottom portion 5. Reference numerals 7 and 8 denote lead wires each having one end connected to the heating element 6.

Reference numerals 9 and 10 denote contacts provided on the bottom portion 11 of the outer body 2, which are connected to the lead wires 7 and 8, and a part of each of the contacts 9 and 10 is outside the bottom portion 11. It projects to the side. A storage battery 12 serves as a power source for the heating element 6, and is detachably attached to the bottom of the container body 1. More specifically, a male screw portion 13 is formed on the outer periphery of the lower portion of the outer body 2 that constitutes the container body 1, and a female screw portion 14 that is screwed into the male screw portion 13 is formed on the upper portion of the storage battery 12. The storage battery 12 is attached to the container body 1 by screwing the female screw portion 14 into the male screw portion 13.

Reference numerals 15 and 16 denote contacts protruding from the upper surface of the storage battery 12, and when the female screw portion 14 of the storage battery 12 is screwed into the male screw portion 13 of the outer body 2 of the container body 1, the contacts 15 and 16 are outside. The contacts 9 and 10 projecting from the bottom 11 of the body 2 are brought into contact with each other, and the heating element 6 is energized via the lead wires 7 and 8.

The electromotive voltage of the storage battery 12 offsets the temperature decrease of the contents contained in the container body 1, and the temperature of the contents is maintained at a temperature close to that when the contents are contained in the container body 1. The voltage is set so as to cause the heating element 6 to generate heat that can be maintained for a time. Reference numeral 17 is a charging plug cord, 18 is an outer lid, 19 is an inner lid, and 20 is a safety valve.

Although the heating element 6 is provided on the bottom portion 5 of the inner body 3 of the container body 1 in the above embodiment, the present invention is not limited to the bottom portion 5. Although the film-shaped heating element 6 is used as the heating element 6, the heating element 6 is not limited to this.

[0012]

[Effect of device]

 As described above, according to the present invention, a heat-insulating container main body is provided with a heating element for generating heat to heat the contents in the container main body, and the container main body heats the heating element. Since the storage battery is detachably installed, by heating the contents inside the container body with the heating element, this heating and the natural temperature decrease of the contents inside the container body cancel each other out. The temperature of the contents can be maintained for a long time at a temperature close to the temperature when placed in the container body, and it can be maintained for a longer time by preparing multiple storage batteries and replacing the storage batteries. Therefore, there is an effect that it is most suitable as a portable heat insulation container used for outdoor sports or outdoor work that is performed for a long time.
