By the way, due to carelessness of the user, the container body whose lid is held in the closed position by the hook member may fall from a normal posture in which the opening of the upper portion of the container body faces upward to a falling posture in which the container body is turned sideways. However, conventionally, when the container body falls down, the lid body opens and there is a possibility that hot water may leak from the container body, and an improvement has been desired.
For example, when the container body whose lid is held in the closed position by the hook member falls from the normal posture to the overturned posture, the hook member is generally in a state where the rear side of the hook member is the front side, It may move so as to draw an arc centering on the bottom, and at the moment when the side of the container body abuts on the table surface or the like, it is the rear side (the direction of detachment from the engaging portion, that is, the hook member) There may be an inertial force that tries to move from the outer diameter side to the inner diameter side in the radial direction of the container body.
In this case, there is a possibility that the hook member moves backward against the urging force of the urging means and detaches from the engaging portion due to the inertial force acting in such a manner. There is a risk of opening.

Therefore, it is assumed that the biasing force of the biasing means is increased in order to prevent the hook member from moving backward due to inertial force when the container body with the lid held in the closed position by the hook member falls down. Is done.
However, when the urging force of the urging means is increased, a large force is required for the user to engage or disengage the hook member by engaging or disengaging the hook member with the engaging portion. It becomes difficult to perform the engagement / disengagement operation.

  The present invention has been made in view of such a situation, and an object of the present invention is to provide a water heating container capable of preventing the lid from opening when it falls down while easily engaging and disengaging the hook member. Is to provide.

In order to achieve the above object, a water heating container according to the present invention comprises: a container main body having an upper opening and an inner container inside; and a lid body capable of opening and closing the opening of the container main body. A hook member that holds the container body in a closed position that closes the opening of the container body is provided on the lid body in a state that it can move forward and backward in the radial direction of the container body and is urged in the forward direction by the urging means. The water heating container provided in the container main body has an engaging portion that engages with a front end portion of the hook member that moves forward by the urging force of the urging means when the lid is positioned at the closed position. There,
The characteristic configuration is that a guide surface that slides and guides the forward and backward movement of the hook member is formed on the lid, and a guided portion formed across the front and rear of the hook member is placed on the guide surface,
When the front part and the rear part of the guided part of the hook member engaged with the engaging part are moved backward in a retractable posture in contact with the guide surface, the hook member does not interfere with the hook member and moves backward. When the rear portion of the guided portion is allowed to move backward with the non-retractable posture separated from the guide surface, a movement preventing portion that interferes with the hook member and prevents the backward movement is provided in the lid body. It is in the point.

According to the above characteristic configuration, when the container body in which the lid is held in the closed position by the hook member is in a normal posture in which the opening portion faces upward, the hook member has the guided portion formed over the front and rear thereof. The hook member can be moved back and forth with its guided portion sliding on the guide surface.
In the present invention, by placing the hook member on the guide surface in this way, a clearance is formed above the hook member, and the hook member engaged with the engaging portion is guided. It is possible to change the posture between a retractable posture in which the front portion and the rear portion of the portion are in contact with the guide surface and a non-retractable posture in which at least the rear portion of the guided portion is separated from the guide surface.
Then, when a force is applied to the hook member so that the hook member moves backward in the retractable posture, the movement preventing portion does not interfere with the hook member, and therefore the hook member is allowed to move backward. On the other hand, when a force is applied to the hook member so that the hook member moves backward in the non-retractable posture, the movement blocking portion interferes with the hook member, and thus the backward movement is blocked.

In addition, when the container body with the lid held in the closed position by the hook member is set in a normal posture on the table surface or the like, when the tip falls over to a falling posture in which the opening portion faces sideways, The hook member engaged with the engaging portion generally moves downward with respect to the table surface or the like while drawing an arc centering on the bottom of the container body, so that the side portion of the container body abuts on the table surface or the like. The inertial force acting on the hook member at the moment is acted so as to move in the front-rear direction of the hook member along the guide surface of the hook member and in the direction away from the guide surface (above the container body). .
For example, when the vehicle falls over with the rear side of the hook member facing forward, the inertial force acting on the hook member at the moment when the side portion of the container body comes into contact with the table surface or the like is along the guide surface of the hook member. The hook member acts so as to move in the rear side (the direction away from the engaging portion) and in the direction away from the guide surface (the upper side of the container main body).
Therefore, when the container body with the lid member held in the closed position by the hook member is in the normal posture, the hook member engaged with the engaging portion is set in the retractable posture, and the container body falls down when the container body falls down. At the moment when the side portion of the main body comes into contact with the table surface or the like, the posture of the hook member engaged with the engaging portion is automatically changed to a non-retractable posture due to inertial force.
Thus, when the container body with the lid held in the closed position by the hook member is in a normal posture, the hook member is in a retractable posture, so that the hook member can be detached from the engaging portion as necessary. The lid can be opened.
Also, when the container body with the lid member held in the closed position by the hook member falls, the posture of the hook member automatically changes to the non-retractable posture, and the movement prevention unit prevents the hook member from retreating. It is possible to prevent the hook member from being detached from the engaging portion and the lid body from being opened.
In addition, when the container body whose lid is held in the closed position by the hook member falls, the hook member is prevented from moving backward by causing the movement preventing portion to interfere with the hook member. In order to prevent the movement, it is not necessary to increase the biasing force of the biasing means, and it is possible to prevent the hook member from being easily engaged and disengaged.
Therefore, it is possible to provide a water heating container that can prevent the lid from opening when it falls, while facilitating the engagement / disengagement operation of the hook member by weakening the urging force by the urging means. .

According to a further feature of the water heating container according to the present invention, the lid is provided with a cover portion that covers an upper portion of the rear end side portion of the hook member,
The movement preventing portion is configured by a protrusion provided on the lower surface, which is a surface on the hook member side, in the cover portion so as to protrude toward the hook member side,
When the hook member engaged with the engaging portion moves backward with the posture incapable of retracting, the upper portion of the rear portion of the hook member is in contact with the protrusion to prevent the backward movement. There is in point.

According to the above characteristic configuration, when the container body with the lid held in the closed position by the hook member falls, the hook member engaged with the engaging portion assumes the non-retractable posture, and the hook member is in the non-retractable posture. Even if the inertial force is applied so that the hook member is moved backward, the upper portion of the rear portion of the hook member comes into contact with the protrusion, and the hook member is prevented from moving backward.
Therefore, it is possible to more accurately prevent the lid from opening when the water heating container falls.

  The water heating container according to the present invention is further characterized in that a portion where the guide surface abuts on a front portion of the guided portion of the hook member engaged with the engaging portion is provided at a rear portion of the guided portion. It is in the point comprised by the 2 step | paragraph shape which becomes higher than the part which contact | abuts.

According to the above characteristic configuration, when the container body with the lid held in the closed position by the hook member is in a normal posture, the hook member engaged with the engaging portion has a two-stage front portion of the guided portion. It is placed on the guide surface in a downwardly inclined posture that abuts the high step portion of the guide surface and the rear portion contacts the low step portion of the two-step guide surface. Therefore, even when the hook member is moved backward, the hook member is in a retractable posture and a rearwardly inclined posture, so that the hook member can be more reliably prevented from coming into contact with the movement blocking portion. Can do.
On the other hand, when the container main body falls from the state in which the hook body engaged with the engaging portion is in the rearwardly inclined posture while the container main body is in the normal posture, the two-stepped shape is obtained in the falling posture. Since the high step portion of the guide surface protrudes above the container main body (in the direction along the table surface or the like on which the container main body is installed) from the low step portion, the hook member engaged with the engagement portion The rear portion is easily separated from the lower step portion of the two-step guide surface, whereby the posture of the hook member can be easily changed to a non-retractable posture.
Therefore, it is possible to more accurately prevent the lid from opening when the water heating container falls.

  A further characteristic configuration of the water heating container according to the present invention is that the space between the high step portion and the low step portion of the two-stage guide surface is configured as an inclined surface that becomes higher as it approaches the high step portion. It is in.

According to the above characteristic configuration, when the hook member moves forward even if the hook member moves backward to a position where the front portion of the guided portion of the hook member descends from the high step portion of the guide surface and contacts the low step portion. The front part of the guided part of the hook member moves forward in such a manner that it slides on the inclined surface from the lower step part of the guide surface and rides on the higher step part.
Therefore, by making the guide surface into a two-step shape, when the container body falls, the posture of the hook member accurately changes to a non-retractable posture, while when the container body is in a normal posture, the hook member is smoothly moved. It can be moved forward.

  The water heating container according to the present invention is further characterized in that the urging means urges the hook member in a forward direction and separates the rear portion of the guided portion of the hook member from the guide surface. It is in the point comprised so that it may urge in a direction.

According to the above characteristic configuration, the urging means urges the rear part of the guided portion of the hook member in the direction away from the guide surface, that is, urges the hook member to return to the non-retractable posture. Therefore, when the container main body with the lid held in the closed position by the hook member falls, the posture of the hook member is surely set in the non-retreatable posture.
Further, when a force is applied to the hook member so that the rear portion of the guided portion of the hook member is brought close to the guide surface against the biasing force of the biasing means, the posture of the hook member can be changed to a retractable posture. Of course.
Therefore, it is possible to more accurately prevent the lid from opening when the water heating container falls.

  The water heating container according to the present invention is further characterized in that the hook member includes a main body portion extending in the front-rear direction and an operation portion extending from the rear end of the main body portion to the upper side in the vertical direction of the hook member. It is in that it is configured.

According to the above characteristic configuration, a force is applied to retract the hook member with respect to the upper end portion of the operation portion of the hook member while the container body in which the lid body is held in the closed position by the hook member is in a normal posture. And the force also acts to bring the rear portion of the guided portion of the hook member closer to the guide surface against the urging force of the urging means, so that the posture of the hook member can be easily changed to the retractable posture. Can do.
Therefore, the posture of the hook member can be surely set to the non-retractable posture when the water heating container is overturned, and the posture of the hook member can be easily changed to the retractable posture when the container main body is in the normal posture.

A further characteristic configuration of the water heating container according to the present invention is that the lid is detachable from the container main body,
A pair of the hook members are provided in a state of being distributed to the opposite side with respect to the center of the lid.

According to the above characteristic configuration, since the lid body is detachable from the container main body, the lid body and the container main body can be separated and easily cleaned.
In addition, since the pair of hook members are provided in a state of being distributed to the opposite side with respect to the center of the lid body, the pair of hook members can reliably hold the lid body on the container body at the closed position. it can.
Therefore, it is possible to facilitate the cleaning of the lid and the container body while ensuring the retention of the lid on the container body.

A further characteristic configuration of the water heating container according to the present invention is that the top opening in the container body falls from a normal posture in which the container is facing upward to a falling posture on a plane that faces in a lateral direction,
The biasing force of the biasing means is that the hook member is set to a biasing force that changes the retractable posture from the retractable posture.

According to the above characteristic configuration, when the container body whose lid is held in the closed position by the hook member falls on the plane, the hook member is attached in the forward direction at the moment when the side portion of the container body abuts the plane. Without being hindered by the urging force of the urging means that urges, the posture of the hook member accurately changes from the retractable posture to the non-retractable posture by the inertial force.
In other words, when the urging force by the urging means is increased, the posture of the hook member is unlikely to change from the retractable posture to the non-retractable posture when the container body whose lid is held in the closed position by the hook member falls. By reducing the biasing force by the biasing means, it is possible to accurately change the posture of the hook member from the retractable posture to the non-retractable posture when the container body falls.
In addition, weakening the urging force by the urging means contributes to facilitating the hook member engaging / disengaging operation.
Accordingly, the hook member can be easily engaged and disengaged, and the lid can be prevented more accurately from opening when the water heating container falls.

That is, as shown in FIG. 7 and FIG. 8, when the operation portion 9 h at the end of the force point side lever member 91 opposite to the side connected to the action point side lever member 92 is moved up and down, When the lever member 91 is swung in the vertical direction, the action point side lever member 92 is swung in the vertical direction in conjunction with the rocking in the vertical direction.
Then, as shown in FIG. 8, when the operation portion 9h on the handle side end of the force point side lever member 91 is pushed down against the biasing force of the spring member 31, the end on the valve mechanism side rises, Along with this, the force point at the end portion on the handle side of the action point side lever member 92 connected to the end portion rises, the action point 9 w at the end portion on the valve mechanism side descends, and the valve element 27 moves to the coil spring 30. The valve mechanism V is pushed down against the urging force, and the valve mechanism V is switched to the open state in which the pouring passage 20 is opened.

Next, a description will be given of a procedure when the lid 200 is attached to or removed from the container main body 100.
When the lid 200 is attached to the container main body 100, the lid 200 is placed on the opening of the container main body 100 in a normal posture with the relative positional relationship for attaching the lid. Then, as shown in FIG. 15B, the front end side lower surface 8 s of the rear end inclined shape at the front end portion 8 </ b> Af of each of the pair of hook members 8 is the front downward inclined shape of the flange 26 of each of the pair of engaging portions 25. The state becomes substantially parallel to the upper surface 26s and comes into contact with the upper surface 26s.
In this state, when the lid 200 is pushed downward, each of the pair of hook members 8 resists the urging force of the coil spring 24 by the guidance of the front downwardly inclined upper surface 26s of the flange 26 of each of the pair of engaging portions 25. Will be retreated.
When the lid 200 is further pushed downward, as shown in FIG. 11, the pair of hook members 8 get over the flange 26 and move forward by the urging force of the coil spring 24 to fit into the pair of engaging portions 25, respectively. The lid body 200 is held by the container body 100 in the closed position.
Thus, when the container body 100 in which the lid 200 is held in the closed position by the pair of hook members 8 is in a normal posture, as shown in FIG. Since it has a downwardly inclined posture, it is possible to reliably move the pair of hook members 8 backward without contacting the pair of protrusions 16p.

  When removing the lid 200 from the container main body 100, as shown in FIG. 11, a force is applied in a direction in which the pair of hook members 8 engaged with the engaging portions 25 are brought close to each other. Then, as shown in FIG. 12, the pair of hook members 8 are moved backward in a state where the respective operation side portions 8 </ b> B pass below the protrusions 16 p on the back surface of the lid cover 16, as shown in FIG. 13. In addition, since the lid body 200 can be lifted as it is, the lid body 200 can be detached from the container body 100. In FIG. 12, (a) shows the main part of the upper surface of the lid 200, and (b) is a view taken in the direction of arrows XIIb-XIIb in (a).

When the force applied to retract each of the pair of hook members 8 is released in a state where each of the pair of hook members 8 is located at the open position, each of the pair of hook members 8 is biased by the coil spring 24. To move forward and return to the free state.
As shown in FIG. 13, in a state where each of the pair of hook members 8 is located at the open position, the protruding portion 8b of each hook member 8 comes into contact with the lower step portion 41d of the guide surface 41 over the entire length thereof. However, since the inclined surface 41s is formed between the low step portion 41d and the high step portion 41h of the guide surface 41, when the hook members 8 move forward, the front ends of the protrusions 8b are guided. The inclined surface 41s is slid from the low step portion 41d of the surface 41 to ride on the high step portion 41h, and each hook member 8 can be smoothly moved forward.

As shown in FIG. 16, when the container body 100 with the lid 200 held in the closed position by the pair of hook members 8 falls to the fall position, the hook member 8 (the front end is a table surface or the like) positioned on the upper side in the fall position. Since the hook member 8) facing the opposite side (upper side) changes its posture to the non-retractable posture due to the inertial force as described above, the inertial force that tries to move backward with respect to the hook member 8 works. In addition, the upper portion 8e of the rear end edge of the hook member 8 hits the pair of protrusions 16p on the back surface of the lid cover 16 to prevent the hook member 8 from moving backward, and the hook member 8 is detached from the engaging portion 25. There is nothing to do.
In addition, when the container body 100 falls to the fall position, the hook member 8 located on the lower side in the fall position (the hook member 8 in which the front end of the hook member 8 faces the table surface or the like (lower side)) is also inertial. Similarly, the posture changes to a non-retractable posture due to the force, and an inertial force is exerted on the hook member 8 to move forward (in the direction of engaging with the engaging portion 25). 8 also does not detach from the engaging portion 25.
Therefore, even if the container body 100 with the lid body 200 held in the closed position by the pair of hook members 8 falls, the lid body 200 is prevented from being detached from the container body 100, so that hot water leaks from the container body 100. Can be prevented.

That is, when the container main body 100 with the lid 200 held in the closed position by the hook member 8 falls, the hook member 8 tries to retreat due to inertial force, but the upper portion 8e at the rear edge is inclined to the lid cover 16. Since the resistance against the movement to the rear side is increased, the back movement of the hook member 8 is prevented. Thus, the hook member 8 can be prevented from being detached from the engaging portion 25.
As a specific example of the movement blocking unit S, when the protrusions 16p as in the above embodiment are applied, the number of the protrusions 16p is not limited to two as in the above embodiment, It may be more than one.
When one protrusion 16p is provided, the protrusion 16p is provided in an elongated shape extending in the horizontal width direction of the hook member 8 and is brought into contact with a wide range in the horizontal width direction of the upper portion 8e of the rear end edge of the hook member 8.
