BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an insulated cooker for accommodating a large amount of liquid food such as stew in a warm state.

[0002]

2. Description of the Related Art Insulated cooking utensils for accommodating liquid foods such as stews in a warm state are well known in the art as disclosed in Japanese Utility Model Laid-Open No. 4-14024.

[0003] The heat-insulated cooking utensil includes a heat-insulating main body container, an inner container which is housed in the main body container so as to be freely taken in and out, and a heat insulating member which closes an opening of the main body container in a state where the inner container is housed. And a lid having a structure.

[0004] By the way, in the case of this insulated cooking utensil, a suspender for lifting the main body container is required, and
A handle for lifting the inner container is also required. On the other hand, since the main body container is to be closed in a hermetically closed state by the lid, it is desirable to position the handle for lifting the inner container in the main body container in consideration of the airtightness. There is a possibility that the temperature of the container may become too high to remove the inner container with bare hands. On the other hand, if the handle on the inner container side is to be positioned outside the main body container, there is a possibility that the tightness of the lid is impaired.

Therefore, in the above-mentioned known example, the hanging handle on the main body container side is omitted, and the handle on the inner container side is exposed to the outside of the main body container, so that it can be disengaged from the engaging member formed on the main body container side. In addition, a notch to be fitted with the handle is formed on the lid side so that a hanging handle for lifting the main body container can also be used as a handle for lifting the inner container, and the tightness of the lid is also ensured. Like that.

[0006]

However, when the handle for taking out the inner container is also used as a hanging handle for lifting the main body container as in the above-mentioned known example, the handle for taking out the inner container protrudes outside the main body container. Therefore, it is necessary to hold the handle with both hands when lifting the main body container, which is not convenient.

The handle for taking out the inner container is an indispensable member, and it is necessary to protrude outward from the main container for the above-mentioned reason. If an attempt is made to provide the handle at a position other than the portion where the handle is formed, the handle and the hanging hand will have a structure protruding from the outer periphery of the main body container, which may impair the appearance of the product. In order to solve such a problem, it is necessary to sufficiently consider the formation position of the hanging hand and to improve the appearance of the product.

The present invention has been made in view of the above points, and has as its object to enable lifting with one hand and not to impair the appearance of a product by devising a mounting position. is there.

[0009]

According to the basic structure of the present invention, as a means for solving the above problems, a main body container having a heat insulating structure, and an inner container for heating and cooking which is housed in the main body container so as to be freely taken in and out. And a lid having a heat insulating structure for closing the opening of the main body container in a state where the inner container is housed, wherein the mating surface of the main body container and the lid body is provided on the inner container. A pair of handles that protrude outwardly are provided, and both ends of the hanging handle for lifting the main body container are supported on a side surface of the main body container and a portion where the handle is protruding, and with one hand. In addition to being easily lifted, the product appearance is improved.

In the basic structure of the present invention, both ends of the hanging hand are pivotally supported on a pivot shaft projecting from a side surface of the lid, and a tip end side of the pivot point is connected to the lid. When the main body container is detachably engaged with the engaging portion protruding from the side surface of the main body container through a gap between the body and the handle, or both ends of the suspender are connected to the upper edge of the main body container. In the case where the supporting member is rotatably supported on a supporting shaft protruding at a position facing the handle, the supporting portion and the locking portion of the suspender are hidden behind the handle. This is preferable in that the exposure of the pivotal and locking parts can be minimized.

Further, in the case where the holding portion is formed with a clamping portion for clamping and holding the handle to the main container when the main container is lifted, the grip can be clamped and fixed to the main container when lifting the main container. It is more preferable in this respect.

It is preferable that the hanging hand be stored along the side of the lid or the side of the main body container when the main body container is not lifted, since the appearance of the product at the time of non-lifting becomes better.
