According to the above characteristic configuration, when the valve operating tool is in the closing operation position, the hook member is allowed to move from the holding position to the open position, and when the valve operating tool is in the opening operation position, the hook member is held. The interference part of the hook member and the interference part of the valve operating tool interfere with each other so as to prevent the movement from the position to the open position.
That is, when the valve operating tool is in the closing operation position, the hook member can be moved from the holding position to the opening position, so that the state in which the lid body is held in the closing position is opened and the lid body is removed. Can do. On the other hand, when the valve operating tool is in the opening operation position, the hook member cannot be moved to the open position. For example, in order to pour hot water from the spout, the water heating container is lifted to open the valve operating tool. When the hook member is moved to the open position when it is positioned at the position, the hook member cannot be moved. In this case, when the valve operating tool is in the open operation position, the state where the lid is held in the closed position cannot be released.
Accordingly, the lid can be prevented from falling off when pouring hot water from the spout, and a water heating container capable of improving safety can be provided.

In order to achieve the above object, a water heating container according to the present invention comprises a container body having an upper opening and an inner container inside, and a lid body capable of opening and closing the opening of the container body. A valve mechanism that can be switched between an open state that allows outflow of hot water in the inner container from the pouring spout and a closed state that prevents the water from flowing out from the spout is provided in the lid body, and the lid body is opened to the container body. A hook member that holds the lid in a closed position is movable between a holding position for holding the lid in the closed position and an open position for releasing the lid. And a valve operating tool for switching the valve mechanism between the open state and the closed state by moving the valve body up and down, and for opening the valve body to the open state and closing the valve body. It can move freely between the closing operation positions Serial A water heating vessel provided in the lid,
The feature configuration is that the hook member and the valve operation tool allow the hook member to move from the closing operation position to the opening operation position of the valve operation tool in the holding position, and the hook member In the open position, an interference portion is provided that prevents the valve operating tool from moving from the closing operation position to the opening operation position.

According to the above characteristic configuration, the movement of the valve operating tool from the closing operation position to the opening operating position is permitted when the hook member is in the holding position, and the valve operating tool is closed when the hook member is in the open position. The interference part of the hook member and the interference part of the valve operating tool interfere with each other so as to prevent the movement from the operation position to the opening operation position.
That is, when the hook member is in the holding position, the valve operating tool can be moved from the closed operating position to the open operating position, so that hot water can be poured from the spout by switching the valve mechanism to the open state. On the other hand, when the hook member is in the open position, the valve operating tool cannot be moved even if it is moved to the open operation position.For example, it seems that the lid body is held in the closed position. When the hook member is not positioned at the holding position when it is not properly held at the closed position, the valve operating tool is It cannot be moved.
Accordingly, the lid can be prevented from falling off when pouring hot water from the spout, and a water heating container capable of improving safety can be provided.

A further characteristic configuration of the water heating container according to the present invention is that the valve operating tool has one end in the longitudinal direction along the radial direction of the container body acting when the lid is positioned at the opening of the container body. A point of action that is located above the valve body as a point and is provided so as to be swingable about a lateral axis centering on a point between the point of action and an end opposite to the point of action in the longitudinal direction. Configured with side lever members,
The valve operating tool is moved from the closing operation position to the opening operation position by swinging the lever member on the action point side in a direction in which the force point that is the end opposite to the action point moves upward. Configured to
With the hook member in the state where the side close to the action point side leverage member is the open position and the side far from the action point side leverage member is the holding position, the fulcrum and force point of the action point side leverage member Provided so as to be movable in the radial direction of the container body when the lid body is positioned at the opening of the container body and intersects the alignment direction,
The portion between the fulcrum force points between the fulcrum and the force point in the action point side lever member is an interference part on the valve operating tool side,
As the interference part on the hook member side, the hook member is provided with a protruding part that protrudes toward the portion between the fulcrum force points,
When the hook member is located at the holding position, the projecting portion is in a state of being close to a lateral side portion of a portion between the fulcrum force points of the action point side lever member located at the opening operation position, and the hook member is When the protrusion is located in the open position, the protrusion is in a state of covering the upper portion between the fulcrum force point portions of the action point side lever member located in the closing operation position, and the protrusion of the hook member It exists in the point comprised so that the part between the fulcrum force points of the said action point side lever member may interfere.

According to the above characteristic configuration, the action point side lever member constituting the valve operation tool is swung in the direction in which the force point, which is the end opposite to the action point, moves upward. Is moved from the closing operation position to the opening operation position, and the valve mechanism is switched to the open state.
Further, the hook member intersects with the direction in which the fulcrum and force point in the action point side lever member are arranged, and is movable in the radial direction of the container body when the lid is positioned at the opening of the container body. When moved to the side closer to the point side lever member, it is moved to the open position, and when moved to the side farther from the action point side lever member, it is moved to the holding position.
When the hook member is in the holding position, the protrusion of the hook member is close to the lateral side of the portion between the fulcrum force points of the action point side lever member located at the opening operation position, and the hook member is opened. When the hook member is in the position, the protrusion of the hook member is in a state of covering the upper part of the portion between the fulcrum force points of the action point side lever member located at the closing operation position. Interference occurs between the fulcrum force points of the lever member.
Therefore, when the hook member is in the holding position, the lever on the action point side can be swung from the closing operation position toward the opening operation position (the portion between the fulcrum force points is moved upward), so that the valve mechanism can be It can be switched to the open state.
On the other hand, when the hook member is in the open position, the protrusion of the hook member is covered close to the upper portion between the fulcrum force points of the action point side lever member located in the closing operation position, and the action point side lever member is Even if the swing operation position is swung from the closing operation position toward the opening operation position (even if the portion between the fulcrum force points is moved upward), the portion between the fulcrum force points of the action point side lever member hits the protrusion of the hook member. The lever member on the action point side cannot be swung, and the valve mechanism cannot be switched to the open state.

When the action point side lever member is in the closing operation position, if a force is applied to the hook member in the holding position in a direction approaching the portion between the fulcrum force points of the action point side lever member, the protrusion of the hook member is Since the hook member can be moved to the open position toward the portion between the fulcrum force points of the action point side lever member in a form covering the portion between the fulcrum force points of the action point side lever member, the lid body is held in the holding position. It is possible to release from the state to be performed, and the lid can be opened.
On the other hand, when the action point side lever member is in the opening operation position, even if a force is applied to the hook member in the holding position in a direction approaching the portion between the fulcrum force points of the action point side lever member, the protruding portion of the hook member Is applied to the side portion between the fulcrum force points of the action point side lever member, so that the hook member cannot be moved toward the portion between the fulcrum force points of the action point side lever member, and the lid body is held in the holding position. Can not be released from.
In short, when the valve operating tool is in the opening operation position, the hook member cannot be moved to the open position, and when the hook member is in the opening position, the valve operating tool cannot be moved to the opening operation position. Therefore, it is possible to reliably prevent the lid from falling off when pouring hot water from the spout, and the safety can be further improved.

According to a further characteristic configuration of the water heating container according to the present invention, the valve operating tool is connected to the action point side lever member and an end corresponding to the force point of the action point side lever member and the action point side lever. An end portion connected to the force point of the member and the end portion is provided with a force point side lever member that can swing around a lateral axis centering on an end portion opposite to the end portion in the longitudinal direction. ,
When the force point side lever member is swung in the vertical direction with the end opposite to the end connected to the action point side lever member as the force point, The action point side lever member is configured to swing in the vertical direction.

  According to the above characteristic configuration, the force point side lever member is operated to move the force point, which is the end of the force point side lever member on the side opposite to the side connected to the action point side lever member, downward to swing the force point side lever member. Then, in conjunction with the swing, the action point side lever member swings so that the force point, which is the end connected to the force point side lever member, moves upward, and the valve operating tool is moved from the closing operation position. The valve mechanism is switched to the open state by moving to the opening operation position.

By the way, with one operating lever provided as a fulcrum that is allowed to abut on the upper part of the valve body with the intermediate portion in the longitudinal direction as an action point and one end in the longitudinal direction is swingable around the lateral axis. A valve operating tool can be configured.
In this case, by pushing down the end of the operating lever opposite to the fulcrum side as a force point, the valve body is moved downward to switch the valve mechanism to the open state.
However, in this case, the length of the operating lever is considerably longer than the length of the force point side lever member and the action point side lever member according to this characteristic configuration, so the distance between the fulcrum and the force point becomes longer. As a result, the distance between the action point and the force point is also increased. Therefore, in order to switch the valve mechanism to the open state, to move the valve body downward by a predetermined amount necessary for switching the valve body from the closed state to the open state, the force point is increased by a considerably large amount (that is, the valve body The amount of movement operation is large, and therefore the operability for switching the valve mechanism to the open state is inferior.
On the other hand, in this characteristic configuration, the length of the force point side lever member and the action point side lever member can be made considerably shorter than the length of the operation lever as described above.
This reduces the amount of vertical movement of the force point in the action point side lever member for switching the valve body from the closed state to the open state by the action point of the action point side lever member to switch the valve mechanism to the open state. Therefore, the amount of swing operation in the vertical direction of the force point side lever member connected to the force point of the action point side lever member can be reduced.
Therefore, the operability for switching the valve mechanism to the open state can be improved.

  A further characteristic configuration of the water heating container according to the present invention is that the color of the hook member is configured to be different from the color of the lid cover that forms the outer peripheral portion of the lid.

According to the above characteristic configuration, since the color of the hook member is different from the color of the lid cover that forms the outer peripheral portion of the lid body, the user can place the hook member in the holding position or in an open position other than the holding position. You can easily see if there is. That is, the user can easily determine the state where the lid is not held in the closed position by the container body.
Accordingly, it is possible to prevent an undesirable operation such as lifting the water heating container and tilting it for pouring hot water even though the lid is not held in the closed position by the container body. It has become possible to further improve the performance.

That is, even if a force is applied in a direction in which the force point side lever member 91 and the action point side lever member 92 are in the opening operation position and the pair of hook members 8 are brought close to each other, the protrusion of each hook member 8 is performed. Since the portion 8m hits the fulcrum force point portion 92a of the action point side lever member 92, each hook member 8 cannot be moved to the open position, and the lid 200 cannot be removed from the container main body 100.

  As shown in FIGS. 12 and 13, when the pair of hook members 8 are in the open position, the protrusions 8m of the hook members 8 are the arm portions of the bifurcated fulcrum force point portion 92a. Even if a force is applied so as to lower the operation portion 9h of the force point side lever member 91 (that is, the portion 92a between fulcrum force points is raised), the portion between the bifurcated fulcrum force points is covered. Since each arm portion of 92a hits the protruding portion 8m of each hook member 8, the force point side lever member 91 cannot be swung, and the valve mechanism V cannot be switched to the open state.
