In order to make it easier to remove the lid of the inner pot placed on the inner pot housed in, and to easily scoop out the contents of the inner pot, the mouth opening of the inner pot is almost the same height as the mouth opening of the outer container. The present invention relates to a heat-insulating cooking container which is lifted up to a certain height and suspended and fixed.

[0002]

2. Description of the Related Art Generally, cooking and cooking of food such as boiled rice is performed by using electric heat or open flame. However, in such a cooking method, boiling or burning is likely to occur due to overheating, and a large amount of energy is consumed. There was such inconvenience. As a cooking utensil to solve this problem, by dipping desired raw vegetables or grains in hot water or boiling broth and keeping the semi-cooked food in a heat-insulated state for a long time A heat-insulating cooking container is known.

[0003] A typical heat-insulating cooking container basically has a heat-insulating outer container such as a vacuum double-wall container, an inner pan that can be stored in and out of the outer container, and the inner pan. It is composed of a heat insulating outer lid that closes the mouth opening of the outer container in a closed state. This inner pot is composed of an inner pot body and an inner pot lid with a knob placed at the opening of its mouth.

In this heat-insulating cooking container, the inner pot is taken out, cooking ingredients are put therein, and the inner pot lid is closed by heating to a temperature at which cooking is possible by an external heat source such as a stove with or without the inner pot lid. Then, by immediately putting it in the outer container and closing the outer lid, the heat is prevented from being dissipated to the outside of the outer container, and cooking such as simmering proceeds without an external heat source.

In this type of heat-insulating cooking container, a handle is required for taking in and out and moving the inner pot. The handle of the inner pot cannot be fixed so as to project outward from the side wall unlike the ordinary pot because of the heat insulating efficiency and the space efficiency. The most common handle for an inner pot used for a heat-insulating cooking container is equipped with two semi-circular vine members whose rotation fulcrums are the two opposing points on the outer periphery of the opening of the inner pot, which are mounted side by side (1 ) When accommodating the inner pot in the outer container, distribute each vine member along the half circumference on the opposite side of the opening of the inner pot and fold it down to accommodate. (2) When removing the inner pot from the outer container Both vine members are erected above the mouth opening and the central part is grasped to lift the inner pot body.

However, in this handle, since the grip portion is located right above the mouth opening of the inner pot, when the grip is gripped, the hand is exposed to heat, which makes handling extremely inconvenient. As a means for solving this problem, Japanese Utility Model Laid-Open No. 34438/1993 discloses a configuration shown in FIG.
The heat-insulating cooking container shown in is proposed. In FIG. 10, this heat-insulating cooking container 50 includes a heat-insulating outer container 51, an inner pot 52 that can be stored in and taken out of the outer container 51, and a mouth opening 51a of the outer container 51 in a state where the inner pot 52 is housed. It has a closing heat insulating outer lid 53.

In the inner pot 52, arm portions 56 rotatable with respect to the inner pot body 52 and a grip portion 55 at the tip thereof are provided at two opposing positions on the outer peripheral portion of the mouth opening 52a of the inner pot body 54.
When the handle 57 having the is attached and the inner pot 52 is housed in the outer container 51, when the handle 57 (1) closes the outer lid 53, the entire handle 57 is placed inside the outer container 10. It is rotated to a position in the vicinity of the mouth opening 52a of the inner pot so as to be housed, and (2) when the inner pot 52 is taken out, the grip portion 55 is used.
Is rotated so that it is located outside the mouth opening 52a of the inner pot 52 and above the mouth opening 51a of the outer container 51,
An insulating cooking container with a rotating handle is proposed.

This heat-insulating cooking container has a handle 5 during heat-insulating cooking.
Since 7 is rotated to the above state (1) and the whole is housed together with the inner pot main body 54 in the outer container 51 and the outer lid 53 can be closed, the inside of the outer container 51 is in a good heat insulating state. To be kept. When the outer lid 53 is opened and the inner pot 52 is taken out, the handle 57 is rotated to the position (2) so that the grip portion 55 is located above the mouth opening 51a of the outer container, so that it is easy to grip.
The inner pot 52 can be easily taken out without exposing the hands to hot air.

[0009]

However, in any of the above-described heat-insulating cooking containers, the inner pot is deeply inserted until it comes into contact with the inner bottom of the outer container during the heat-insulating cooking, and the mouth opening of the inner pot body is opened. Is located considerably below the mouth opening of the outer container. For this reason, at the end of cooking, when you open the outer lid, remove the inner pot lid without taking out the inner pot, and scoop out the cooked contents with a scoop, the contents will be in a deep position. Not only was it difficult to scoop out, but there was a danger that the hands would be exposed to the heat because the surrounding area was surrounded by high temperature heat. Further, when the inner pot lid is removed by hand while the inner pot is housed in the outer container, the handle sometimes interferes with removal.

The present invention has been made to solve this problem, and therefore an object thereof is to easily move the inner pot into and out of the inner pot, and in the state where the inner pot is housed in the outer container, the heat insulating effect and the space efficiency are achieved. (EN) A heat-insulating cooking container which is excellent, and in which the inner pot lid placed on the inner pot is easy to remove and the contents of the inner pot are easily scooped out.

[0011]

[Means for Solving the Problems] The above-mentioned problems are solved by an outer container having a heat insulating property, an inner pan which can be stored in and taken out from the outer container, and a mouth opening of the outer container while the inner pan is housed. In a heat-insulating cooking container having a heat-insulating outer lid for closing the inner pot, the inner pot has a handle composed of an arm portion rotatably connected to the inner pot body at a fulcrum fulcrum and a grip portion at its tip. Then
With the inner pot housed in the outer container, this handle (1)
A storage position in which the entire handle is near the mouth opening of the inner pot and is housed in the outer container with the outer lid closed, and (2) at least a part of the grip portion is outside the mouth opening of the outer container. When the handle is in the above-mentioned deployed position, the arm part serves as a lever with the rim of the outer container as a fulcrum, and the mouth part of the inner pot is pivotable. The handle is formed so that the inner pot body is lifted and suspended until the opening is almost level with the mouth opening of the outer container, and the handle locking means that locks the handle in the deployed position so as to maintain the suspended state. This can be solved by providing an insulated cooking container provided.

The handle locking means is provided at the rotation fulcrum portion and comprises a rotation shaft and a bearing hole into which the rotation shaft is inserted, and the rotation shaft has a polygonal cross section having at least two parallel sliding surfaces. The bearing hole is formed into a columnar shape, and the bearing hole is formed into a keyhole-like square shape in which a circular opening portion and a square opening portion are connected to each other, and the circular opening portion has a diameter capable of freely rotating the rotating shaft, The rectangular opening may have a width capable of sliding on the sliding surface of the rotating shaft, and the rotating shaft can be moved to the rectangular opening when the handle is at least in the deployed position. .

Further, the above-mentioned handle locking means is provided at the rotation fulcrum portion and comprises a rotation shaft and a bearing hole into which the rotation shaft is inserted.
The rotating shaft is formed in a polygonal column shape having at least two parallel sliding surfaces, and a head member having a diameter larger than that of the rotating shaft is attached to the tip of the rotating shaft. It is formed in a shape in which a passage opening portion, a rotary shaft moving opening portion, a circular opening portion and a rectangular opening portion are connected in series, and the head member passage opening portion has a shape and dimension capable of passing the head member perpendicularly to its surface. However, the rotating shaft moving opening has a width that allows the rotating shaft to move parallel to the surface thereof, the circular opening has a diameter that allows the rotating shaft to freely rotate, and the square opening has The pivot shaft may have a width that can slide on the sliding surface of the pivot shaft so that the pivot shaft can move to the rectangular opening when the handle is at least in the deployed position.

Further, the handle locking means is composed of an upwardly extending elastic locking lever mounted on a shoulder member extending outwardly from the rim portion of the outer container, and a hook portion formed at the tip thereof. The handle may be locked at the deployed position by engaging the hook with the handle. The handle locking means may be other than the above, and the present invention is not limited by the type of the handle locking means.

[0015]

[Operation] The handle is rotatable with respect to the main body of the inner pot, and in its storage position, the entire handle is compactly housed in the outer container with the outer lid closed near the mouth opening of the inner pan. Therefore, the handle does not interfere with the heat insulating effect and does not impair the space efficiency during the heat retention cooking.

When the handle is in the unfolded position, the arm serves as a lever to lift the inner pot main body with the mouth edge of the outer container as a fulcrum, and the handle locking means maintains this suspended state. The opening is held at substantially the same height as the mouth opening of the outer container. This makes it easier to remove the inner pot lid without interfering with the handle, and also the contents of the inner pot body,
The hands will not be exposed to the heat, making it easier to scoop. In addition, when the inner pan is taken in and out or moved, the handle can be carried with the handle standing above the inner pan.

If the handle locking means comprises a polygonal prism-shaped rotation shaft and a rectangular bearing hole, the rotation shaft has a circular opening when the handle is in the storage position and while the handle is rotating. When the handle is in the deployed position and the arm is pulled or pushed, the rotating shaft is slidably inserted into the rectangular opening and the handle is prevented from rotating in this state. . Therefore, the inner pot can be held in a suspended state in which the opening of the inner pot is substantially flush with the opening of the outer container.

(Embodiment 1) FIGS. 1 and 2 show two different modes in a preferred embodiment of the heat-insulated cooking container of the present invention. In FIG. 1, the heat-insulating cooking container 1 includes a heat-insulating outer container 2 having a vacuum double-wall structure, an inner pot 3 that can be stored in and out of the outer container 2, and an inner pot 3. It has a heat-insulating outer lid 4 that closes the mouth opening 2a of the outer container 2 in this state. At the mouth opening 3a of the inner pot 3, an inner pot lid 3c having a knob 3b attached at the center is placed.

In this inner pot 3, connecting members 36, which are riveted to each other, are mounted at two opposing positions on the outside of the peripheral edge of the mouth opening 3a, and a rotary fulcrum 32 provided at the tip end thereof. It has a handle 35 composed of an arm portion 33 rotatably connected and a grip portion 34 at its tip.

The handle 35 can be rotated between two positions with the inner pot 3 accommodated in the outer container 2. Hereinafter, the first position will be referred to as the "storage position" and the second position will be referred to as the "deployment position". FIG. 1 shows an aspect of the heat insulating cooking container 1 in which the handle 35 is at the storage position. As shown in FIG. 1, in the storage position, the handle 35 is
The whole is in the vicinity of the mouth opening 3a of the inner pot and is housed in the outer container 2 with the outer lid 4 closed.

FIG. 2 shows a state of the heat insulating cooking container 1 when the outer lid 4 is opened and the handle 35 is rotated to the deployed position. However, the outer lid 4 is not shown in FIG. As shown in FIG. 2, in the deployed position, the handle 35 is arranged such that the grip portion 34 is located on the upper outside of the mouth opening 2 a of the outer container 2. At this position, the handle 35 serves as a lever with the arm portion 33 serving as a fulcrum with the mouth edge portion 21 of the outer container 2 so that the mouth opening 3a of the inner pot 3 has substantially the same height as the mouth opening 2a of the outer container 2. It is formed so that the inner pot main body 31 is lifted up and suspended until it reaches the end. Further, the rotation fulcrum portion 32 is provided with handle locking means for locking the rotation of the handle 35 in a state where the inner pan body 31 is suspended.

The handle locking means of this embodiment is shown in FIG.
The handle locking means 40 is formed on a seat plate 37 extending from both sides of the tip of the coupling member 36 and fixed to the seat plate 37 in a vertically outward direction, and a rotary shaft 41 formed at an end of the handle arm 33. And a bearing hole 42 into which is inserted. The rotating shaft 41 is formed in a prismatic shape having a square cross section having parallel sliding surfaces 41a and 41b. The bearing hole 42 is
The circular opening 42a and the rectangular opening 42b are formed in a continuous keyhole-shaped rectangular shape, and the circular opening 42a has a diameter capable of freely rotating the rotating shaft 41. 42b has a width that allows the sliding surface 41a, 41b of the rotary shaft 41 to slide. In this embodiment, the rotary shaft 41 and the bearing hole 42 form the rotary fulcrum portion 32.

The operating mode of the handle 35 is shown in FIGS. FIG. 4 shows the handle 35 in the storage position. At this time, the rotary shaft 41 is attached to the circular opening 4 of the bearing hole 42.
The handle 35 is in a rotatable state on the 2a side, and the grip portion 34 is housed so as to be located near the mouth opening 3a of the inner pot 3.

When the inner pot 3 is taken out from the outer container 2, the outer lid 4 is opened, and as shown in FIG. The shaft 41 is slidably moved to the side of the rectangular opening 42b of the bearing hole 42 to prevent the rotation, so that the handle 35 does not wobble during carrying. This position of the handle 35 is called an "upright position".

When the inner pot 3 is housed in the outer container 2 again, the handle 35 fixed in the upright position descends by its own weight due to the inner pot 3 coming into contact with the inner bottom of the outer container 2 and the rotating shaft 41. Moves to the side of the circular opening 42a. Therefore, the handle 35 is rotatable and can be returned to the storage position.

When the user wants to scoop out the contents with the inner pot 3 kept in the outer container 2 when the adiabatic cooking is completed,
When the outer lid 4 is opened and the grip portion 34 is gripped and the handle 35 is further rotated beyond the upright position as shown in FIG. 6, the handle arm portion 33 comes into contact with the rim portion 21 of the outer container 2. become.

When the grip 35 is further rotated and pushed down until the grip portion 34 comes into contact with the shoulder member 22 extending outward from the rim portion 21 of the outer container 2, the grip 35 is moved to its arm portion 33.
Serves as a lever with the rim 21 of the outer container 2 as a fulcrum, and as shown in FIG. 7, until the mouth opening 3a of the inner pot 3 becomes substantially the same height as the mouth opening 2a of the outer container 2. The inner pot body 31 is lifted and suspended. At this time, when the handle 35 is pulled horizontally toward the outer side of the outer container 2, the rotation shaft 41 moves the square opening 42.
Sliding to side b. Therefore, the handle 35 is fixed to the deployed position and does not rotate, and the inner pot body 3 is held in a suspended state even when the hand is released.

In this state, since the handle 35 is horizontally opened along the shoulder member 22 of the outer container 2, the handle and the inner pot lid may interfere with each other when the inner pot lid 3c is removed. Absent. Even when scooping out the contents, the contents are lifted from the mouth opening 2a of the outer container 2 to a shallow position, so that the contents can be taken out easily, and the hands are less likely to be exposed to the surrounding hot air. Furthermore, since the handle 35 is fixed at this deployed position, the inner pot 3 can be taken out of the outer container 2 and moved in this state, and the handle does not wobble when heated by an external heat source, so it is easy to handle. .

When the handle 35 is returned from the deployed position to the storage position, if the handle 35 is pushed inward of the outer container 2, the rotating shaft 41 moves to the circular opening 42a side, so that the handle 35 is released from the locking. The outer container 2 can be easily rotated to the storage position.
Housed within. At this time, it goes without saying that the inner pot body 31 descends to the inner bottom of the outer container 2 by its own weight.

(Embodiment 2) The heat insulating cooking container of Embodiment 2 is
It is the same as the first embodiment except that the structure of the handle locking means is different. As shown in FIG. 8, the handle locking means 43 in the heat insulating cooking container of the second embodiment is a prism having a square cross section fixed to the seat plate 37 extending from both sides of the tip of the handle connecting member 36 vertically outward. The rotary shaft 44, a disk-shaped head member 45 fixed to the tip of the rotary shaft 44 and having a diameter larger than the cross section of the rotary shaft 44, and formed at the end of the arm portion 33.
4 is inserted into the bearing hole 46.

The bearing hole 46 has a shape in which a head member passage hole 47, a rotary shaft passage hole 48, a circular opening portion 46a, and a rectangular opening portion 46b are linearly continuous from the grip portion 34 side. There is. The head member passage hole 47 has a shape and dimension that allows the head member 45 to vertically pass through the arm portion 33. The rotation shaft passage hole 48 has a width that allows the rotation shaft 44 to pass while sliding parallel to the arm portion 33. The circular opening 46a and the rectangular opening 46b have the same shape and dimensions as those shown in the first embodiment.

When attaching the handle 35 to the seat plate 37 of the connecting member 36, the handle locking means 43 inserts the head member 45 into the head member passage hole 47 and allows the head member 45 to pass therethrough, and then rotates the rotating shaft 44. Circular opening 4 along passage hole 48
6a to complete the installation. The handle 35 attached in this way can be rotated from the storage position to the deployed position by the same operation as in the first embodiment.
Further, it can be locked by pulling out the grip portion 34 in the upright position and the deployed position.

The handle locking means 43 is not only convenient for attaching the handle 35, but also the head member 45 prevents the arm part 33 from flexing outward due to external force during use. Therefore, the handle 35 does not fall off the rotating shaft 44.

(Embodiment 3) The heat insulating cooking container of Embodiment 3 is
It is the same as the first embodiment except that the structure of the handle locking means is different. As shown in FIG. 9, in the heat-insulated cooking container according to the third embodiment, the rotation fulcrum portion 32 that connects the arm portion 33 of the handle and the connection member 36 is formed by a general, for example, rotatable riveting. ing. The handle locking means 43 in this embodiment is formed on the shoulder member 22 extending outward from the rim portion 21 of the outer container 2. That is, a locking lever 23 made of an elastic material such as synthetic resin or metal extends upward from the tip of the shoulder member 22, and a hook 24 formed inward and downward is provided at the tip thereof. The tip of the grip portion 34 of the handle 35 in the deployed position is the hook portion 24.
To engage with.

When the inner pot 3 is kept warm, the handle 35 can be rotated to be housed in a storage position near the upper portion of the mouth opening 3a of the inner pan 3. Further, when the inner pot 3 is taken out from the outer container 2, the grip portion 34 can be grasped and the handle 35 can be vertically lifted and pulled up as it is.

When the handle 35 is further rotated beyond the upright position, the handle arm portion 33 comes into contact with the rim portion 21 of the outer container 2 and lifts the inner pot main body 31 by the lever principle to suspend it. The tip of the grip portion 34 contacts the hook portion 24. When the grip 34 is further pushed, the locking lever 2
Since 3 has elasticity, the hook portion 24 is pushed outward by the grip portion 34 and flexes outward, and when the handle 35 reaches the deployed position along the shoulder member 22, it is released and returns to its original position. Engage. As a result, the handle 35 is locked in the deployed position.

In this state, even if the handle 35 tries to rotate in the upright position direction due to the weight of the inner pot main body 31, it cannot rotate because the grip portion 34 is engaged with the hook portion 24. In order to release this locking, it is sufficient to simply push the hook portion 24 outward with the fingertip. As a result, the grip portion 34 is released from the engagement with the hook portion 24, and the handle 35 is automatically rotated in the upright position direction by the weight of the inner pot main body 31.

The handle locking means 43 of this embodiment has an advantage that no special processing is required for the rotary fulcrum portion 32 of the inner pot. The shape of the handle locking means described above is not limited to that shown in each of the above embodiments. Any means, such as a screw type, a pin type, a snap ring type, and a pinching type, can be applied as long as the handle can be releasably locked at the deployed position.

[0039]

In the heat-insulated cooking container of the present invention, the inner pan has a rotatable handle, and this handle is rotatable between the storage position and the deployed position. It is housed in an outer container near the mouth opening of the inner pot with the outer lid closed, and the handle hinders the heat insulating effect during heat retention cooking, and the space efficiency of the outer container is impaired. Never.

When the handle is in the deployed position, the grip is outside the mouth opening of the outer container, and the arm serves as a lever with the rim of the outer container as a fulcrum to lift the inner pot body. Since the handle is locked so that the handle locking means keeps the suspended state, the mouth opening of the inner pot is held at approximately the same height as the mouth opening of the outer container, and when removing the inner pot lid. Since the handle does not interfere with the above and the contents of the inner pot are lifted to a relatively shallow position from the mouth opening of the outer container, you can easily scoop out without exposing your hands to heat. .

When the handle locking means is formed of a polygonal prism-shaped rotating shaft and a rectangular bearing hole, the handle does not wobble even in the upright position, and the handle can be fixed in the deployed position even when the inner pot is taken out. Therefore, not only can the inner pot be taken in and out and moved at this position, but it is also convenient for handling when cooking with an external heat source.

If the head member is attached to the tip of the rotary shaft, the rotary shaft will not be separated from the bearing hole even if an external force is applied.

If the handle locking means comprises an elastic locking lever extending upward mounted on a shoulder member extending outward from the rim of the outer container, and a hook portion formed at the tip thereof. Since the turning fulcrum of the handle does not require special processing, it can be manufactured at low cost.
