Description

  The present invention comprises a container main body having an upper opening and an inner container inside, and a lid body that can open and close the opening of the container main body, and the lid body is in a closed position for closing the opening of the container main body. The hook member to be held is in a state where the lid body is movable forward and backward in the radial direction of the container body and biased in the forward direction when the lid body is positioned at the opening of the container body in the closed position. The lower surface of the front end portion of the hook member is provided in a body, and is configured to have a rearward downward inclined shape that is farther away from the upper surface toward the rear side, and the rearwardly downwardly inclined lower surface of the hook member is in contact with the container body. As the lid body is moved downward from the state and positioned at the closed position, a concave portion that fits a front end portion of the hook member and holds the lid body at the closed position is the container body. Related to the water heating vessel

Such a water heating container starts from a state where the lid body is positioned at the opening of the container body so that the lower inclined surface of the hook member comes into contact with the container body, and the lid body is moved downward toward the closed position. By moving the hook member, the hook member is retracted against the urging force in the forward direction, and the upper edge of the recess is moved over, and the front end of the hook member is fitted into the recess, thereby closing the lid. Is to be held.
Incidentally, specific examples of such a water heating container include, for example, an electric kettle, an electric kettle, a humidifier, and a rice cooker.

The hook member is provided in a state of projecting from the side peripheral surface of the lid body, and the lid body is fitted into the opening of the container body by moving the lid body downward toward the closed position. Thus, the hook member is configured to fit into the recess.
In addition, the lower surface of the front end portion of the hook member is formed so as to be inclined downwardly, and when the lid body is moved downward toward the closed position, the hook member is brought into contact with the member above the recess in the container body. Thus, it is configured to be able to smoothly retreat against the urging force, and to smoothly get over the upper edge of the recess and fit into the recess. In addition, since the lower surface of the front end part of the hook member is formed to be inclined downwardly, the front end of the hook member is sharpened to some extent in order to prevent a half-hanging state to be described later.

By the way, the concave portion is provided on the inner side of the opening edge of the container main body, etc., but when the lid is held by the container main body in the closed position, the concave portion and the hook member fitted in the concave portion are externally provided. In order to improve the external appearance so as not to be visible, the concave portion is provided so as not to penetrate the outer peripheral side of the container body (that is, in a bottomed shape having a bottom on the outer peripheral side).
On the other hand, when the hook member is provided so that the foremost end is in contact with the bottom of the recess while being fitted in the recess, the fitting of the hook member into the recess (complete closure of the lid) is repeated. The foremost end of the hook member that collides with the bottom of the recess is worn away, and the foremost end surface is expanded. As described above, when the foremost end surface of the hook member becomes a surface expanded in the vertical direction, the foremost end (frontmost end surface) of the hook member moves above the recess or the recess when the lid is moved downward. It becomes easy to get caught in the edge, and it becomes easy to be in a balanced state (hereinafter sometimes referred to as a half-hanging state) by catching on the member above the recess or the upper edge of the recess. Therefore, a state in which the opening of the container main body is not properly closed by the lid is likely to occur. In such a state, if the water heating container is accidentally turned over, the lid may be opened. is there.

  Therefore, conventionally, when the hook member fits into the recess, the foremost end of the hook member fits into the recess so that the foremost end of the hook member does not collide with the bottom of the recess. The lid is provided with an advance prevention receiving portion for receiving the hook member to prevent advancement before reaching the bottom of the recess (for example, see Patent Document 1).

Japanese Patent No. 3220565

However, in the conventional water heating container, as a result of the cover body being provided with an advance prevention receiving portion for preventing the front end of the hook member from colliding with the bottom of the recess when the hook member is fitted into the recess. The hook member provided on the lid is always received by the forward movement preventing receiving portion, and when the hook member is positioned at the foremost portion in the movable range, the protruding length of the hook member from the side peripheral surface of the lid is It must always be shorter.
That is, when the hook member is fitted into the recess (when the lid is in the closed position), and the hook member is not fitted into the recess and is positioned above the recess, the lid is the opening of the container body. In any case, the hook member is received by the advance prevention receiving portion provided on the lid. Further, when the hook member is fitted into the recess (when the lid is in the closed position), the foremost end of the hook member does not collide with the bottom of the recess. For this reason, in a state where the hook member is positioned at the foremost part in the movable range, the foremost end of the hook member is naturally positioned above the recess and on the radially inner side of the lid body than the position corresponding to the bottom of the recess. Will do. Therefore, the hook member fits into the recess when the cover member is placed in the opening of the container body with the hook member positioned above the recess without being fitted into the recess. The protrusion length of the hook member from the side peripheral surface of the lid body is always shortened, and cannot be longer than the protrusion length of the hook member when the lid body is in the closed position.

  Therefore, in the conventional water heating container, the hook member has a rear lowering lower surface received by a member above the recess in the container body, and the lid is placed on the opening of the container body. Since the protrusion length from which the member protrudes from the side peripheral surface of the lid is shortened, the gap between the outer periphery of the lid and the edge of the opening of the container body is narrowed, and the opening of the container body is reliably secured by the lid. Even if it is in a state that is not closed (hereinafter sometimes referred to as an incompletely closed state), it is difficult for the user to visually recognize the gap and to determine the incompletely closed state.

  On the other hand, if the forward stop receiving portion as described above is omitted and the foremost end of the hook member collides with the bottom of the concave portion when the hook member is fitted into the concave portion, the lid body is placed at the opening of the container body. In the mounted state, it is possible to lengthen the protruding length of the hook member protruding from the side peripheral surface of the lid. However, as described above, since the foremost end of the hook member is easily worn, it is likely to be in a half-hanging state and it is difficult to determine the incompletely closed state.

  The present invention has been made in view of such circumstances, and an object of the present invention is to provide a water heating container that can easily determine the incompletely closed state of the hook member while ensuring the pointed front end of the hook member. It is in.

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, and is movable forward and backward in the radial direction of the container body when the lid is positioned in the opening of the container body in the closed position; The lower surface of the front end portion of the hook member, which is biased in the forward direction, is configured to have a rearward downward inclined shape that is farther away from the upper surface toward the rear side, and the rearward lowering of the hook member. From the state in which the inclined lower surface is in contact with the container body, the front end portion of the hook member is fitted into the lid body as the lid body is moved downward and positioned at the closed position. The recess that holds the closed position Its characteristic feature a water heating vessel provided in the container body, the front end of the hook member is configured into a shape having a receding portion that is recessed from the foremost end,
In the state where the front end portion of the hook member is fitted in the concave portion, the forward movement of the hook member is prevented by contacting only the retracted portion at the front end portion of the hook member with the concave portion forming member forming the concave portion. The forward stop receiving portion is provided.

  According to the above characteristic configuration, when the front end portion of the hook member is fitted into the recess, only the retreating portion at the front end portion of the hook member comes into contact with the advance prevention receiving portion, so that the foremost end of the hook member is at the bottom of the recess. Since the forward movement of the hook member is prevented without colliding, even if the hook member is repeatedly fitted into the recess, the wear of the foremost end of the hook member can be suppressed. Thereby, the front end of the hook member can be maintained in a sharp state, and the lid is opened to the container main body so that the rearwardly inclined lower surface of the hook member abuts the member above the recess in the container main body. When the lid is moved downward from the state (hereinafter sometimes referred to as “free state”) to the fitting position (closed position), the foremost end of the hook member is located above the recess or the recess. It is possible to effectively suppress the occurrence of an incompletely closed state due to a half-hanging state that is caught on the upper edge of the.

In addition, since the advance prevention receiving portion for receiving only the retracted portion at the front end portion of the hook member is provided in the concave portion forming member of the container body, the hook member protrudes from the side peripheral surface of the lid body in the free state. The length can be made longer than the protruding length at the fitting position (closed position). That is, the foremost end of the hook member at the fitting position (closed position) in a state in which the retracted portion of the hook member is in contact with the advance prevention receiving portion of the container body is located radially inward from the position corresponding to the bottom of the recess. Will be located. On the other hand, in the free state, the retracted portion of the hook member does not come into contact with the advance prevention receiving portion of the container body, so that the foremost end of the hook member is positioned radially outward from the position corresponding to the bottom of the recess. Is possible. Thereby, the protrusion length from the side peripheral surface of the lid body in the free state in the hook member becomes long, and in the free state, the gap between the outer peripheral portion of the lid body and the edge of the opening of the container body is increased. Is possible. Therefore, since the gap due to the incompletely closed state becomes relatively large, the user can easily visually recognize the gap and can easily determine the incompletely closed state.
Therefore, it is possible to provide a water heating container that can easily determine the incompletely closed state of the hook member while ensuring the state where the front end of the hook member is sharp.

  The further characteristic structure of the water heating container which concerns on this invention exists in the point by which the said recessed part formation member is comprised by the lip member which forms the edge of the opening part of the said container main body.

According to the above characteristic configuration, since the recess is provided in the lip member that forms the edge of the opening of the container main body, when the lid is separated from the opening of the container main body, substantially the entire opening of the container main body Will be released.
Accordingly, it is possible to facilitate the supply of hot water and the like to the inner container and the cleaning of the inner container.

A further characteristic configuration of the water heating container according to the present invention is that a pair of the receding portions are provided on both sides in the width direction of the hook member,
The forward stop receiving portion is provided in a pair corresponding to the pair of backward portions.

According to the above characteristic configuration, the pair of retreating portions on both sides in the width direction at the front end portion of the hook member are received by the pair of advance prevention receiving portions, so that the front end of the hook member does not collide with the bottom of the recess. It is securely held in the recess in an appropriate posture.
Therefore, since the wear of the front end of the hook member can be accurately suppressed, the occurrence of the incompletely closed state due to the half-hanging state can be more effectively suppressed.

  A further characteristic configuration of the water heating container according to the present invention is that the receding portion and the advance prevention receiving portion are each formed in a planar shape so as to come into contact with each other while being in surface contact with each other.

According to the above characteristic configuration, when the hook member is fitted into the recess, the retreating portion of the hook member and the advance prevention receiving portion abut on each other in a surface contact state. Can be ensured.
Further, since the retreating portion and the advance prevention receiving portion collide with each other in surface contact, a relatively loud collision sound is generated when the hook member is fitted into the recess, and the lid body is used by the user by the collision sound. It becomes easier to recognize that the body is properly held.

A further characteristic configuration of the water heating container according to the present invention is provided with a half-hanging state display portion on the cover that forms the outer periphery of the hook member or the lid,
Between the fitting posture in which the hook member is in contact with the forward movement receiving portion of the recess forming member and prevented from moving forward, and the retracted posture in which the hook member is located behind the fitting position. The half-hanging state display unit is configured to be switched between a state where it is exposed to the outside and a state where it is not exposed due to a difference in interference state between the lid cover and the hook member.

According to the above characteristic configuration, the half-hanging state display unit accurately determines when the hook member is in the fitting position located at the fitting position (closed position) and when the hook member is in the retracted position located behind the fitting position. It can be distinguished and discriminated.
In other words, when the hook member is in a retracted position located behind the fitting position, the hook member may be in a half-hanging state, so the incompletely closed state display unit accurately recognizes the half-hanging state. can do.
Therefore, the user can accurately recognize the incompletely closed state due to the half-hanging state of the hook member.

A further characteristic configuration of the water heating container according to the present invention is provided with a free state display portion on a lid cover that forms an outer peripheral portion of the hook member or the lid,
Between the fitting posture in which the hook member abuts on the advance prevention receiving portion of the recess forming member and is prevented from moving forward, and the forward posture in which the hook member is positioned forward of the fitting position. The free state display unit is configured to switch between a state where it is exposed to the outside and a state where it is not exposed due to the difference in the interference state between the lid cover and the hook member.

According to the above characteristic configuration, when the hook member is in the fitting posture positioned at the fitting position (closed position) and when the hook member is in the forward posture positioned forward of the fitting position by the free state display unit. It is possible to distinguish and discriminate accurately.
That is, when the hook member is in the forward movement position positioned forward of the fitting position, since the hook member is in the free state, the free state can be accurately recognized by the free state display unit.
Accordingly, the user can accurately recognize the incompletely closed state due to the hook member being in the free state.

It is configured to switch between a state and an unexposed state.

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 relative positional relationship for attaching the lid with the pair of hook members 8 in a free state. Put. Then, the rearwardly inclined lower surface 8s of the front end portion 8Af of each of the pair of hook members 8 is substantially parallel to the upper downwardly inclined upper surface 26s of the flange 26 of each of the pair of concave portions 25 and comes into contact with the upper surface 26s. It becomes a state.
As described above, when the lid 200 is placed on the opening of the container body 100 with the pair of hook members 8 in a free state, the free state display sheet 37 is visible from the outside. Therefore, the user can accurately recognize that the hook member 8 is in a free state and the container body 100 is not properly closed by the lid 200 and is in an incompletely closed state.
Further, in the free state, the retreating portion 8r of the hook member 8 does not come into contact with the advance prevention receiving portion 36 of the container body 100. Located outside the direction. Thereby, in the free state, the protruding length of the hook member 8 from the side peripheral surface of the lid body 200 in the free state becomes long, and the rear lower surface 8s of the hook member 8 in the free state is recessed in the container body 200.
