Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention provides a heat-retaining container for a pot suitable for use in a cooking method in which the ingredients are boiled in a pot, and then the pot is removed from the heating source and kept warm to boil depending on the residual heat of the pot and the boiled material to boil. In particular, the present invention relates to the one capable of supporting both a general-purpose double-sided saucepan and a single-sided saucepan.

[0002]

[Prior art]

 Recently, a cooking method in which the ingredients are boiled in a pan and then the pan is boiled and boiled according to the residual heat amount of the pan and the boiling material while keeping the pan warm from the heating source without heating (for example, JP (See Sho 63-248355, Jitsufairoku 5-3162, Jitsufairoku 3-6275, etc.).

According to such a cooking method, the heating time is significantly shortened as compared with the normal cooking method in which heating is continued even after boiling, so that energy saving can be achieved, as well as nutritional value and taste ( (Tasting), fragrance, etc. are less likely to be impaired, boiling over (deformation) is less likely to occur, and there is no spilling or charring, so there is no need to monitor for a long time, which is a great advantage. .

[0004]

[Problems to be solved by the device]

 As described above, in order to simmer and boil only after heat retention after boiling, a heat retention means for the ingredients is required in addition to the pot. Conventionally, as the heat retaining means, as described in the above-mentioned Japanese Utility Model Publication No. 3-6275, etc., a main body (outer pot) and a lid body made of a heat insulating material for accommodating a pot (usually a double-handed pot) It often consists of (outer lid).

However, in the conventional heat insulating container for a pot, which is a body and a lid as a heat insulating means, the pan and the heat insulating container are made as a pair, and one heat insulating container has a dimensional shape. There is a problem that it can be applied only to a very limited range of pots, and if it is applied to pots with a slightly different size and shape, the heat retaining capacity will be significantly reduced. In other words, since the conventional heat insulation container for pots is not versatile, it cannot be used for a wide variety of pans in general households, and a pan and a heat insulation container must be manufactured and sold as a set. It was expensive because it had to be done.

The inventors of the present application are developing and studying a heat-retaining container that is compatible with existing pots, and in the process, the side peripheral walls 60b and 70b of each other are oriented in the height direction as shown in FIG. A hot pot container 2 comprising a bottomed cylindrical main body 60 and a lid 70 fitted together was devised and prototyped. The main body 60 and the lid 70 of the pot heat retaining container 2 are made of a material having excellent heat insulating properties, for example, styrofoam, and the tip ends of the side walls 60b and 70b of the main body 60 and the lid 70, respectively. From the top and bottom edges toward the bottom wall (top wall) 60a, 70a, a pair of rectangular shapes for protruding the handles of both hand pans (not shown; one hand pan is shown in the figure). Opposed notch openings 61 1, 62 and 71, 72 are formed.

In this case, if the inner diameters of the main body 60 and the lid 70 are set to about 25 to 30 cm, a commonly-used double-handed ladle having a diameter of about 18 to 24 cm is used, and its handle is provided with the opposed notch opening 61 of the main body 60. , 62 can be housed in the main body 60 in a state of being projected outward, and the lid 70 can be inserted into the main body 60 from above so that the positions of the opposed notch openings 61 and 71, 62 and 72 are aligned with each other. When fitted, a slight gap is created between the handle of the pan and the opposed notch openings 61 and 71 and 62 and 72, but a substantially hermetically sealed space is formed on the outer circumference of the pan. It

Therefore, if both hand pans are put in the heat-retaining container 2 after boiling the material, the heat-retaining power of the heat-retaining container 2 keeps the boiled material in a high temperature state for a long time without heating. As described above, in the heat insulating container 2, since the pair of opposed notch openings 61, 62 and 71, 72 are formed in the main body 60 and the lid body 70, respectively, a large number of types of both-hand pans having different sizes and shapes can be used. It can be accommodated in the heat insulation container 2 without creating a large opening gap, and thus, sufficient heat insulation performance is exhibited for many types of both-hand pans.

However, it is not limited to a double-handed pan that is used for cooking such as simmering and boiling in a general household, and a single-handed pan may be used. Therefore, it is desirable to use not only a double-sided hot pot but also a single-sided hot pot with various sizes and shapes as the heat-retaining container. As shown in FIG. 4, there is a problem in heat retention performance. That is, in order to put the one-handed pan 50 into the heat-insulating container 2, the handle 51 is moved outside from one of the opposed notch openings 61 and 71 and 62 and 72 (the opening 62 and 72 side in the figure). If the handle 51 is taken out from one of the facing notch openings 61 and 71 and 62 and 72, the other opening side (the front side openings 61 and 71 side in the figure). ) Remains wide open, and also on one opening side (openings 62 and 72 side in the figure), the openings 62, 72 (61, 72) have their widths adjusted to the handles of both pans. Therefore, it is too wide for the bar-shaped handle 51 of the one-handed pan, and a large gap is formed between the openings 62, 72 (61, 72) and the handle 51. Therefore, even if the one-handed pan 50 is housed in the heat insulation container 2, heat escapes to the outside from the two opposed notch openings 61 and 71 and 62 and 72, and the heat cannot be sufficiently kept. .

In view of the above points, the present invention provides sufficient heat retention performance, can be easily and inexpensively manufactured, and is suitable for a wide variety of both-purpose and single-use pans with different sizes and shapes. It is an object of the present invention to provide a heat-insulating container for a pot that can be effectively handled.

[0011]

[Means for Solving the Problems]

 The pot heat retaining container according to the present invention is basically composed of a bottomed cylindrical main body and a lid body whose side peripheral walls are fitted along the height direction, and the main body and the side peripheral wall of the lid body. A pair of opposed notch openings for projecting the handles of the two-handed pans from their respective tips toward the bottom wall, and one side peripheral wall of the main body or lid. In addition to the pair of opposed notch openings from the tip toward the bottom wall, there is a narrow notch opening narrower than the opposed notch opening for protruding the handle of the one-handed pan out. Formed.

[0012] The shape of the main body and lid of the pot heat retaining container of the present invention is preferably close to the shape of a commonly used pot such as a bottomed cylinder or a square tube, but is not limited thereto. However, the side peripheral wall of the lid may be externally fitted or inserted (internally fitted) with respect to the side peripheral wall of the main body, that is, the horizontal sectional area of the main body and the lid ( Any of them may have a large diameter, and the narrow cutout opening for the handle of the one-handed pan may be formed in either the main body or the lid.

As the material of the main body and the lid body which compose the heat-insulating container for a pot of the present invention, resin foam having excellent heat insulating property, corrugated cardboard, etc. can be used, but not limited thereto. It does not need to be made of a material and may have a multi-layer structure or a hollow structure. When a resin foam is used as the material of the main body and the lid, the resin species may be polystyrene resin, polyolefin resin, or the like. The polystyrene resin is not limited to a homopolymer of a styrene monomer, but includes a copolymer. The styrene-based monomer includes methylstyrene, ethylstyrene and the like in addition to styrene. Further, the copolymer contains a copolymer containing styrene monomer in an amount of 50 mol% or more. Examples of the counterpart monomer for copolymerization include methacrylic acid esters such as methyl methacrylate, acrylic acid esters, acrylic acid, methacrylic acid, acrylonitrile, and maleic anhydride. The heat resistant polystyrene resin having such heat resistance can be most preferably used. Examples of the polyolefin resin include polyethylene, polypropylene, copolymers thereof, copolymers with other copolymerizable polymers, and mixtures thereof. A resin obtained by copolymerizing a polyethylene resin and styrene can also be preferably used.

On the other hand, the size and shape of the notch opening is not particularly limited, but it is preferable to make it rectangular or elongated according to the size, position, etc. of the handle of the pot to be used. As one of the above, in addition to the basic structure, at least one of the main body and the lid is covered with a sheet-like material or a film-like material having excellent heat radiation property such as an aluminum foil or an aluminum vapor-deposited resin film. Some are mentioned. In this case, as the sheet-like material or the film-like material having excellent heat radiation property, a thin material having a thickness of about 5 μ to 500 μ is desirable, and as the material, the aluminum foil, polyester such as resin, PC, etc. are used. Aluminum vapor-deposited resin film or the like can be used.

[0015]

[Work]

 In the heat-insulating container for a pot having the above-mentioned configuration, when the two-handed pot is kept warm, the handle is inserted into the main body with the handles protruding from the pair of opposed notch openings formed in the main body. After that, if the lid is externally or internally fitted to the main body from above so that the positions of the facing notch openings are aligned with each other, a slight gap is created between the handle of both hands and the facing notch opening. However, the narrow cutout opening for one-handed pan formed in one of the main body and the lid is closed by the side wall part of the side where it is not formed (main body or lid), and it is substantially formed on the outer periphery of both pans. A hermetically sealed space is formed. Therefore, if both hands are placed in the heat-retaining container after boiling the material, the heat-retaining power of the heat-retaining container keeps the boiled material in a high temperature state for a long time without heating.

On the other hand, when keeping the one-handed pan warm, for example, in the case where a narrow cutout opening is formed on the main body side, the one-handed pan is placed outside the narrow cutout opening of the main body. After inserting the lid body into the main body in a state of protruding, the lid body is externally or internally fitted to the main body from above.At that time, of the pair of opposed notch openings formed in the lid body. Align one side with the narrow cutout opening formed in the main body (where the handle of the one-handed pan is already inserted), and fit the lid to the main body. As a result, although there is some gap between the handle of the one-handed pan and the narrow cutout opening, the pair of opposed cutout openings formed in the main body is closed by the side wall of the lid, and the lid body is closed. The other side (opposite to the handle) of the pair of opposed notch openings formed on the side is closed by the side wall of the main body, so that a substantially airtight space is formed on the outer periphery of the one-handed pan. Therefore, if the one-handed pot is placed in the heat-retaining container after boiling the material, the heat-retaining power of the heat-retaining container keeps the boiled material in a high temperature state for a long time without heating.

When a narrow cutout opening is formed on the lid side, the lid of the one-handed pan is held in the opposite cutout opening with the handle of the one-handed pan protruding outward from the opposite cutout opening of the main body. The lid is fitted to the main body by aligning the positions of the narrow cutout openings. As described above, in the pot heat retaining container of the present invention, the main body and the lid are respectively formed with a pair of opposed notch openings for both hands pans, and only one of them has a narrow notch opening for one hand pan. Since it is formed, it is possible to store various types of double-sided pans and single-sided pans with different dimensions and shapes in the heat insulation container without creating a large opening gap. It is possible to exert sufficient heat retention performance.

In addition, by covering the inner wall surface of at least one of the main body and the lid with a sheet-shaped material or a film-shaped material having excellent heat radiation properties such as an aluminum foil or an aluminum vapor-deposited resin film, a sheet-shaped material or Since the membranous material is thin, the amount of heat taken from the pan in the heat insulation container is small, and the heat retention of the pan is further increased by the radiation of heat by the sheet or the membranous material.

【Example】

 Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 shows an embodiment of a pot heat retaining container according to the present invention. The illustrated pot heat retaining container 1 comprises a bottomed cylindrical main body 10 and lids 20 to which side peripheral walls 10b and 20b are fitted along the height direction. The main body 10 and the lid 20 Is made of a material having excellent heat insulating properties, for example, Styrofoam.

Here, the main body 10 has a diameter of about 27 cm and a height of about 27 cm so that a double-sided pan and a single-sided pan having a diameter of about 18 to 24 cm, which are commercially available, can be accommodated as described later. Has a height of about 17 cm and a wall thickness of about 1.5 cm, and the lid 20 has a diameter of about 30 cm, a height of about 12 cm, and a wall thickness of about 1.5 cm. In addition, the lid 20 is pushed onto the upper end of the side peripheral wall 10b of the main body 10 until the bottom wall (top wall) 20a of the lid 20 is in contact with the main body 10 for external fitting.

Then, the side walls 10b and 20b of the main body 10 and the lid 20 are respectively attached to the side pans 10b and 20b from their tips (upper end and lower end) toward the bottom walls (top wall) 10a and 20a. A pair of rectangular opposed notch openings 11, 12 and 21, 22 for projecting to the bottom are formed, and the side peripheral wall 10b of the main body 10 is further provided with the pair of opposed notch openings from the tip to the bottom wall. In addition to the cutout openings 11 and 12, a narrow cutout opening 13 is formed which is narrower in width than the opposed cutout openings 11 and 12 for allowing the handle of the one-handed pan to protrude to the outside.

In addition to the above, in the present example, a sheet-like material or a film-like material having excellent heat radiation properties is formed so as to cover the inner surface of the bottom wall 10a and the inner surface of the side peripheral wall 10b and the inner surface of the bottom wall 20b of the lid. Aluminum vapor-deposited resin films 15a, 15b and 25a having a total thickness of 5 μ to 500 μ are attached. Polyester is used here as the resin film of the aluminum vapor deposition resin film.

In the heat insulation container 1 of the present embodiment having the above-described structure, as shown in FIG. 2, when the two-handed pan 40 is kept warm, the handles 41 and 42 are formed on the main body 10. After being inserted into the main body 10 while protruding from the pair of opposed notched opening portions 11 and 12, the lid body 20 is attached to the main body from above to cover the opposed notched opening portions 11 and 21 and 12 and 22, respectively. Fit it in place so that it fits together. As a result, although a slight gap is created between the handles 41 and 42 of the two-sided pan 40 and the facing notch openings 11, 21 and 12, 22, one-sided pan formed on one of the main body 10 and the lid 20. The narrow cutout opening 13 for use is closed by the side wall portion 20b of the lid body 20 in which the narrow cutout opening 13 is not formed, and a substantially hermetically sealed space is formed on the outer periphery of the both hands pan 40. Therefore, if both hands pans 40 are put in the heat-retaining container 1 after boiling the material, the heat-retaining power of the heat-retaining container 1 keeps the boiled material in a high temperature state for a long time without heating.

On the other hand, as shown in FIG. 3, when warming the one-handed pan 50, the one-handed pan 50 is kept in a state in which the handle 51 of the one-hand pan 50 is projected from the narrow cutout opening 13 of the main body 10 to the outside. After being placed in the cover 10, the lid 20 is fitted onto the main body 10 from above. At that time, one of the pair of opposed notch openings 21 and 22 formed in the lid 20 is fitted. (21 in the figure) and the narrow cutout opening 13 formed in the main body 10 (the handle 51 of the one-handed pan 50 is already inserted), and the lid 20 is fitted to the main body 10. . As a result, although a small gap is created between the handle 51 of the one-handed pan 50 and the narrow cutout opening 13, the pair of opposed cutout openings 11 and 12 formed in the main body are formed on the side wall of the lid 20. The side wall portion 10b of the main body 10 closes the other of the pair of opposed cutout openings 21 and 22 (22 located on the side opposite to the handle 51) closed by the portion 20b. Therefore, a substantially hermetically sealed space is formed on the outer periphery of the one-handed pan 50. Therefore, if the one-handed pan 50 is placed in the heat-retaining container 1 after boiling the material, the heat-retaining power of the heat-retaining container 1 keeps the boiled material in a high temperature state for a long time without heating.

As described above, in the pot heat retaining container 1 of this embodiment, the main body 10 and the lid 20 are provided with the pair of opposed notch openings 11 and 12 for the two-handed pot 40, respectively, and the one-handed pot is provided. Since the narrow cutout opening 13 for use is formed, it is possible to accommodate various types of both-handed pans and one-handed pans having different sizes and shapes in the heat insulating container 1 without causing a large opening gap. As a result, sufficient heat retention performance can be exhibited for both double-handed and single-handed pots.

Further, since the entire inner wall surface of the main body 10 and the bottom wall surface 20a of the lid body 20 are covered with the aluminum vapor-deposited resin films 15a, 15b and 25a, the heat radiation caused by the aluminum vapor-deposited resin films 15a, 15b and 25a further increases the heat retaining ability of the pot. In addition, since the aluminum vapor-deposited resin films 15a, 15b, and 25a are thin, the amount of heat taken from the pan in the heat-retaining container is small, and the heat-retaining performance is remarkably improved.

Moreover, since the heat insulating material is good as the constituent material of the main body 10 and the lid body 20, the material cost is low, and the light and easy-to-handle resin foam such as Styrofoam is used, the heat insulating container having excellent heat insulating performance can be easily formed. Moreover, it can be provided at low cost. The facing notch opening and the narrow notch opening of the body and the lid may be formed at the same time when the body and the lid are formed. It may be formed by cutting (corresponding to the position of the handle of the pot to be used).

[0028]

[Effect of device]

 As can be understood from the above description, the heat insulating container for a pot according to the present invention has a simple structure and can obtain sufficient heat insulating performance, can be easily and inexpensively manufactured, and has a commonly used size. It has an excellent effect that it can reasonably correspond to various types of double-sided pots and single-sided pots with different shapes.

Further, by covering the inner wall surface of at least one of the main body and the lid with a sheet-shaped material or a film-shaped material having excellent heat radiation properties such as an aluminum foil or an aluminum vapor-deposited resin film, a sheet-shaped material is obtained. Alternatively, since the film-like material is thin, the amount of heat taken from the pan in the heat-retaining container is small, and the heat-insulating performance of the pan can be significantly improved by the radiation of heat by the sheet-like material or the film-like material. Furthermore, by using a resin foam such as Styrofoam for the constituent material of the main body and the lid, it is possible to easily and inexpensively provide a heat insulating container having excellent heat insulating performance.
