A plurality of concavo-convex parts are formed on the surface of the heating body 16, with a ratio of a press-bonding area that is a ratio of the area of the concave parts 14 to the area of the concavo-convex parts, being 20 to 80%. With this configuration, since the heating body 16 contains the concavo-convex parts having the press-bonding area ratio described above, a surface of object can be heated more uniformly by preventing overheating at the heating body 16, thereby suppressing occurrence of such problems as local overheating, scorching, and deformation at the heating auxiliary member.

Description

  The present invention relates to a heating auxiliary member for imparting burnt or crispy feeling to a heated object when the heated object is heated in a microwave oven.

  Various methods of cooking food using a microwave oven have been proposed. For example, Japanese Patent Laying-Open No. 2008-289692 (Patent Document 1) discloses a microwave packaging container as a heating auxiliary member in which a heating element is attached to the bottom surface of a paper container. This microwave oven packaging container contains an object to be heated such as pizza or okonomiyaki and is used by heating it in a microwave oven. Then, the heating element generates heat due to the dielectric heating of the microwave oven, and the generated object can be burnt to give a crispy texture as freshly made.

  Japanese Laid-Open Patent Publication No. 3-503243 (Patent Document 2) discloses a laminate as a heating auxiliary member including a metal layer that generates heat by interacting with microwaves in a microwave oven. A large number of ridges are formed on one side of the laminate. Such a bulge forms a space between the food to be heated and the laminate, so that moisture released from the food can be efficiently discharged to the outside and sufficient heat conduction can be provided.

  However, the conventional heating auxiliary member has a problem that the heating auxiliary member itself is burnt due to overheating when heated in a microwave oven.

  In addition, there is a request to repeatedly use the heating auxiliary member as described above instead of single use. However, when the above burning occurs, the burnt portion is not suitable for repeated use. In particular, there is a problem that the heating auxiliary member cannot be repeatedly used.

  This invention is made | formed in order to solve the above subjects, and the objective of this invention is to provide the heating auxiliary member which can be utilized repeatedly.

  The inventor of the present invention has completed the present invention while conducting research on a configuration for enabling repeated use of the heating auxiliary member. That is, by forming a concavo-convex portion in the heating element constituting the heating auxiliary member, and further setting the pressure-bonding area ratio, which is a ratio of the area of the concave portion to the area of the concavo-convex portion, within a numerical range of 20% to 80%, The present inventors have obtained new knowledge that defects such as occurrence of overheating in the auxiliary member and peeling of the heating element from the support portion constituting the heating auxiliary member can be suppressed. The heating auxiliary member according to the present invention completed based on the above knowledge includes a heating element having a conductive material layer capable of induction heating by microwave irradiation, and a plurality of irregularities are formed on the surface of the heating element. The crimping area ratio, which is the ratio of the area of the recess to the area of the concavo-convex part, is 20% or more and 80% or less.

  In this way, since the heating element includes an uneven portion having the above-described pressure-bonding area ratio, by preventing overheating in the heating element, the surface of the object to be heated can be heated more uniformly, It is possible to suppress the occurrence of problems such as local overheating, burning and deformation in the heating auxiliary member. Therefore, it is possible to obtain a heating auxiliary member that can be used repeatedly and has excellent durability.

  In the heating auxiliary member, the pressure-bonding area ratio is preferably 20% or more and 60% or less, and the pressure-bonding area ratio is more preferably 25% or more and 40% or less. In this case, generation | occurrence | production of problems, such as local overheating in a heating auxiliary member, a burn, and a deformation | transformation, can be suppressed more reliably. In addition, the reason why the lower limit value of the crimping area ratio is set to 20% is that the effect of preventing overheating is not significant when the crimping area ratio is smaller than this value. Moreover, the upper limit value of the pressure-bonding area ratio is set to 80% because when the pressure-bonding area ratio becomes larger than this value, the contact area between the heated object and the heating element becomes too small, and the surface of the heated object is heated ( This is because there is a problem that baking cannot be performed sufficiently.

  ADVANTAGE OF THE INVENTION According to this invention, the heating auxiliary member which can suppress the generation | occurrence | production of the damage by burning or local overheating and which can be used repeatedly can be obtained.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. In the following drawings, the same or corresponding parts are denoted by the same reference numerals, and description thereof will not be repeated.

(Embodiment 1)
As shown in FIG. 1, the heating auxiliary member 1 according to the present invention includes a support portion 20 and a heating element portion 26 formed on the surface of the support portion 20. The heating element portion 26 includes the heating element 16 and the adhesive 19. The heating element 16 is fixed to the surface of the support portion 20 with an adhesive 19. In addition, the planar shape of the heat generating body 16, the adhesive agent 19, and the support part 20 is square shape. In addition, the planar shape of the support part 20 can be made into many arbitrary shapes. For example, it may be a polygonal shape such as a circular shape, an elliptical shape, a triangular shape, or a pentagonal shape. The shape of the heating element 16 is also a quadrangular shape, but may be any other shape (for example, a polygonal shape such as a circular shape, an elliptical shape, a triangular shape, or a pentagonal shape). The size of the heating element 16 is smaller than the size of the support portion 20, but may be the same as the size of the support portion 20. The heating element 16 is disposed at a substantially central portion of the surface of the support portion 20. Around the heating element 16, the outer peripheral surface of the support portion 20 is exposed. In addition, you may comprise the heating auxiliary member 1 only with the heat generating body 16, without using the support part 20. FIG.

  Further, in the heating auxiliary member 1 according to the present invention, the heating element 16 is formed with uneven portions. The concavo-convex portion may be formed by, for example, embossing, and a plurality of concave portions 14 and convex portions 25 are formed between the concave portions 14. The concave portion 14 and the convex portion 25 are formed by rolling or pressing the heating element 16. The plurality of recesses 14 may be arranged, for example, in a matrix shape or a lattice shape, but may be randomly arranged. The depth H of the recess 14 can be set to an arbitrary depth.

  The heating element 16 is configured to generate heat to such an extent that the object to be heated can be scorched by irradiating electromagnetic waves of a microwave oven, particularly microwaves, and specifically, generates heat to about 170 to 250 ° C. ing. The heating element 16 can have various configurations, but can have a configuration including a metal thin film made of at least aluminum, nickel, gold, silver, zinc, platinum, or the like. For example, as shown in FIG. 3, the heating element 16 may have a laminated structure such as a paper 18, an adhesive 15, an aluminum (Al) vapor deposition layer 12, and a resin layer 13 made of PET. The resin layer 13 is not particularly limited as long as it is heat resistant to the heat generated by the Al vapor deposition layer 12, but a film having metal thin film vapor deposition processing suitability is used. For example, a polyethylene terephthalate film (PET) having a thickness of 9 μm to 50 μm is suitable. The thickness of the metal thin film such as the Al vapor deposition layer 12 is preferably in the range of 50 to 150 angstroms. As a specific example of such a heating element 16, for example, Susceptor (registered trademark) manufactured by Toppan Printing Co., Ltd. is commercially available.

  Here, the crimping area ratio in the heating auxiliary member 1 according to the present invention will be described. With reference to FIG. 2 and FIG. 4, the case where the several recessed part 14 is arrange | positioned at the surface of the heat generating body 16 at the matrix form is considered. The width of the concave portion 14 is Y, and the total width of one concave portion 14 and the convex portion 25 adjacent to the concave portion 14 is X. Note that the distance between adjacent recesses 14 is W (= X−Y). The pressure-bonding area ratio is defined as (Y × Y) / (X × X) × 100 (%). In other words, the crimping area ratio indicates the ratio of the area of the recess 14 to the constant area on the surface of the heating element 16. That is, if the crimping area ratio is large, it means that the occupied area of the recess 14 is relatively large. If the crimping area ratio is small, it means that the occupied area of the recess 14 is relatively small. The pressure-bonding area ratio is preferably 20% or more and 80% or less. If it does in this way, generation | occurrence | production of the damage by scorching and local overheating will be suppressed, and the heating auxiliary member 1 can be used repeatedly. Accordingly, it is possible to obtain the heating auxiliary member 1 that can be used repeatedly and has excellent durability.

  Further, the cross-sectional shapes of the concave portion 14 and the convex portion 25 may be substantially rectangular as shown in FIG. 2, but may be trapezoidal as shown in FIG. In this case, the width Y of the concave portion 14 is measured at the upper end portion of the concave portion 14 (that is, at the same level as the upper surface of the convex portion 25) as shown in FIG.

  Moreover, as shown in FIG. 6, when the cross-sectional shape of the convex part 25 is semicircular (that is, the convex part 25 is a hemispherical shape), the total width X of the concave part 14 and the convex part 25 is shown in FIG. Thus, it is set as the distance between the centers of a pair of adjacent convex portions 25. The width Y of the concave portion 14 is a distance between the surfaces of the adjacent convex portions 25 at a position away from the center of the convex portion 25 by a predetermined distance L. For this distance L, for example, a value such as 50% of the radius of the semicircle that is the cross-sectional shape of the convex portion 25 can be used.

  Further, in the planar shape of the heating element 16, the plurality of recesses 14 may be arranged in a matrix shape or a lattice shape, for example, but may be arranged at random. Moreover, the uneven part may be formed by embossing, for example. The depth of the recess 14 can be set to an arbitrary depth. For example, as the planar shape of the heating element 16, a plurality of concave portions 14 as grooves extending linearly as shown in FIG. 7 may be formed. The plurality of recesses 14 include a group of recesses 14 extending in parallel to each other and another group of recesses 14 extending so as to intersect the group of recesses 14. As a result, between the concave portions 14, convex portions 25 (see FIG. 7B) whose planar shape is a parallelogram or rhombus are formed.

  As shown in FIGS. 8 and 9, the planar shape of the heating element 16 is such that the concave portions 14 having a circular planar shape (a cross-sectional shape is also semicircular as shown in FIG. 9) are arranged in a triangular lattice shape. A configuration may be adopted. Moreover, between the adjacent recessed parts 14, the convex part 25 whose planar shape is circular shape (a cross-sectional shape is also semicircle shape as shown in FIG. 9) may be formed. The depth H of the recess 14 in the configuration shown in FIG. 9 is basically defined by the same definition as the depth H in the configuration shown in FIG. On the other hand, for the concavo-convex portion having such a shape, the width Y of the concave portion 14, the total width X of one concave portion 14 and the convex portion adjacent to the concave portion 14, and the distance W between the adjacent concave portions are basically It can be defined in the same manner as in the configuration shown in FIG.

  That is, referring to FIG. 9, the total width X of the concave portion 14 and the convex portion 25 is the distance between the centers of a pair of adjacent convex portions 25 as in the case shown in FIG. The width Y of the concave portion 14 is a distance between the surfaces of the adjacent convex portions 25 at a position away from the center of the convex portion 25 by a predetermined distance L. For this distance L, for example, a value such as 50% of the radius of a semicircle that is the cross-sectional shape of the convex portion 25 (more specifically, for example, the radius of curvature at the central portion of the convex portion 25) can be used. Further, as shown in FIG. 9, the width of the convex portion 25 corresponds to the distance W between the adjacent concave portions 14.

  Next, with reference to FIG. 10, the manufacturing method of the heating auxiliary member 1 by this invention mentioned above is demonstrated. As shown in FIG. 10, in the manufacturing process of the heating auxiliary member 1, first, a heat generating film preparation process (S 10) is performed. Specifically, a heat generation film including a conductor layer to be the heat generator 16 is prepared. As a structure of the heat generating film, a film having a laminated structure like the heat generating element 16 shown in FIG. 3 can be used.

  Next, a processing step (S20) is performed as shown in FIG. Specifically, for example, by performing roll processing on the prepared heat generating film with a roll having an uneven shape formed on the surface thereof, the uneven shape formed on the surface of the roll is transferred to the heat generating film. As a result, the heating element 16 can be obtained. If such a transfer technique is used, the uneven | corrugated shaped part of arbitrary structures can be formed in a heat generating film by changing the uneven | corrugated shape of the roll surface used for roll processing.

  Next, the sticking process (S30) shown in FIG. 10 is implemented. Specifically, the heating element 16 is attached to the surface of the support portion 20 made of, for example, paper. The heating element 16 is fixed to the support portion 20 using, for example, an adhesive 19 or the like. In this way, the heating auxiliary member 1 shown in FIG. 1 can be obtained.

  In the processing step (S20), when the heat generating film is roll processed, if both surfaces of the pair of rolls sandwiching the heat generating film are subjected to uneven processing, as shown in FIG. Clear irregularities can be formed on both the front and back surfaces of the heating element 16. Here, FIG. 11 shows the heating auxiliary member 1 using the heating element 16 in which clear uneven portions are formed on the front surface and the back surface, respectively. The heating element 16 is fixed to the surface of the support portion 20 with an adhesive 19. Since the adhesive 19 is disposed so as to fill the concave portion of the concave-convex shape portion on the back surface of the heating element 16, the contact area between the adhesive 19 and the heating element 16 is sufficiently large. Therefore, the adhesive strength of the heating element 16 to the support portion 20 is improved.

  On the other hand, in the above-described processing step (S20), if only one of the pair of rolls used for roll processing of the heat generating film is subjected to uneven processing, as shown in FIG. On the other hand, a clear uneven portion can be formed on the surface opposite to the back surface facing the support portion 20, while the back surface of the heating element 16 has a smooth curved surface along the shape of the uneven portion on the front surface side. Uneven portions are formed. The heating auxiliary member 1 shown in FIG. 1 can also be manufactured by sticking such a heating element 16 to the support portion 20 using the adhesive 19.

(Embodiment 2)
A second embodiment of the heating auxiliary member according to the present invention will be described with reference to FIGS. As shown in FIG. 13, the heating auxiliary member 1 includes a first support part 2 on which the first heating element 4 is formed, a second support part 3 on which the second heating element 5 is formed, and the first support part 2. And a connecting portion 6 that connects the second support portion 3 to each other. The 1st support part 2 and the 2nd support part 3 function as a support body of the 1st heat generating body 4 and the 2nd heat generating body 5 which are mentioned later. The first support portion 2 and the second support portion 3 are formed in substantially the same shape and size.

  The first support part 2 and the second support part 3 are formed with folds 21 and 31 at the center thereof so that the first support part 2 and the second support part 3 can be valley-folded. As shown in FIG. 14, the folds 21 and 31 are constituted by cutout portions 21a and 31a and folding lines 21b and 31b, and circular portions 21c and 31c (the planar shape is substantially circular) at the center thereof. Are formed). In this way, by forming at least a part of the fold lines 21 and 31 as the cutout parts 21a and 31a, the first support part 2 and the first support part 2 can be used when heated compared to the case where the fold lines 21 and 31 are formed only by the fold lines 21b and 31b. It is possible to more effectively prevent the second support portion 3 from returning to the expanded state. Further, the first support part 2 and the second support part 3 can be formed of paper, non-woven fabric, woven fabric, sponge, urethane, or the like. Among these, particularly, the oil content from the heated object F (see FIG. 16). And from the viewpoint of absorbing moisture, it is preferably formed of paper, non-woven fabric, woven fabric, or the like. Further, from the viewpoint of discarding the heating auxiliary member 1 after using it a plurality of times, it is preferable to form the first support portion 2 and the second support portion with paper, nonwoven fabric or the like.

  As shown in FIG. 13, the connecting portion 6 connects the left end of the first support portion 2 and the right end of the second support portion 3 at two locations, and each connecting portion 6 has a plurality of intervals. It is formed as a connecting body 62 (two in FIG. 13). Each connecting body 62 has a fold 61 formed at the center thereof, and the connecting body 62 can be bent along the fold 61 so as to be a valley fold. By bending the connecting body 62, the second support portion 3 approaches the first support portion 2 (that is, the second support portion 3 moves so as to overlap the first support portion 2) and is formed in the second support portion 3. The configured second heating element is configured to come into contact with the object to be heated F.

  The length of the coupling body 62, that is, the distance between the first support portion 2 and the second support portion 3, also varies depending on the object to be heated F sandwiched between the first support portion 2 and the second support portion 3. For example, in the case where the object to be heated F is a fillet fish or a cut piece of meat, it is preferably 5 mm to 50 mm. In addition, when one fish whole such as block meat, thick sliced bread, fish, salmon, salmon, etc. is to be heated F, the interval is preferably 15 mm or more and 100 mm or less. By setting it within this range, the heating auxiliary member 1 can be fitted to the shape of the article F to be heated. In addition, as a material of this connection body 62, although not specifically limited, paper, a nonwoven fabric, etc. can be mentioned.

  A first heating element 4 is formed on the first support portion 2, and a second heating element 5 is formed on the second support portion 3. Each of the heating elements 4 and 5 basically has the same configuration as the heating element 16 described in the first embodiment. The first heating element 4 and the second heating element 5 have the same configuration. That is, the first heating element 4 and the second heating element 5 are sheet-like, and the first heating element 4 and the second heating element 5 have substantially the same shape and size. And the crimping | compression-bonding area ratio in the 1st heat generating body 4 and the 2nd heat generating body 5 is 20% or more and 80% or less.

  In this case, similarly to the heating auxiliary member 1 according to the present invention, overheating of the first heating element 4 and the second heating element 5 can be prevented, so that the surface of the object to be heated can be heated more uniformly and the heating auxiliary member It is possible to suppress the occurrence of problems such as local overheating, burns and deformation.

  In addition, when the heating auxiliary member 1 is used repeatedly, the occurrence of a problem that the first support portion 2 or the second support portion 3 is locally burned by the heat generated from the first heating element 4 or the second heating element 5, This can be suppressed as compared with the case where a flat heating element is used. For this reason, the frequency | count of repeated use of the heating auxiliary member 1 can be increased.

  The size of the first heating element 4 and the second heating element 5 is smaller than that of the first support part 2 and the second support part 3. And the 1st heat generating body 4 and the 2nd heat generating body 5 are supported by adhere | attaching on the center part of the 1st support part 2 and the 2nd support part 3, respectively with an adhesive agent etc. As can be seen from FIG. 13, the outer peripheral edge portions of the first support portion 2 and the second support portion 3 are provided with areas that are not covered by the first heat generating element 4 and the second heat generating element 5 and are exposed.

Next, the usage method of the heating auxiliary member 1 described above will be described.
First, as shown in FIG. 15, the heating auxiliary member 1 is bent in the valley fold direction at the folds 21 and 31 before the use, as shown in FIG. 62 is also accommodated in a bag-like or box-like packaging container (not shown) in a state of being folded in the valley folding direction at the fold 61.

  Thus, the heating auxiliary member 1 accommodated in the packaging container is taken out from the packaging container, and the heating auxiliary member 1 is spread as shown in FIG. And the to-be-heated material F is mounted on the 1st heat generating body 4 of the 1st support part 2. As shown in FIG. And as shown in FIG. 16, the connection body 62 is bent along the crease | fold 61, and the 2nd support part 3 is covered on the to-be-heated material F. As shown in FIG. At this time, the second heating element 5 is in contact with the upper surface of the object to be heated F. Moreover, since the 2nd support part 3 is bent along the crease | fold 31, the 2nd heat generating body 5 is contacting the to-be-heated material F in a wider area. Further, since the heating auxiliary member 1 is housed in the packaging container in a state in which the second support portion 3 and the connecting body 62 are bent, the heating auxiliary member 1 has a habit in a state in which the connecting body 62 and the second supporting portion 3 are bent. . Accordingly, the first support portion 2 and the second support portion 3 as shown in FIG. 13 spread from the state in which the object to be heated F is sandwiched between the first support portion 2 and the second support portion 3 as shown in FIG. It can be prevented that the state returns to the state.

  In this way, the heated object F is sandwiched between the first support part 2 and the second support part 3, that is, the first heating element 4 is brought into contact with the lower surface of the heated object F, and the upper surface of the heated object F is contacted. Dielectric heating is performed using a microwave oven while the second heating element 5 is in contact. As a result, the heated object F itself is heated by dielectric heating, and the first heating element 4 and the second heating element 5 are dielectrically heated to generate heat up to about 170 to 250 ° C., and contact the heating element in the heated object. Heat the heated surface to about 160-210 ° C. As a result, the bottom and top surfaces of the object to be heated F are simultaneously burnt.

  In addition, when the 1st heat generating body 4 and the 2nd heat generating body 5 contact, there exists a possibility of overheating, but the outer-periphery edge part which is a part which the 1st support part 2 and the 2nd support part 3 are easy to mutually contact Is exposed (that is, the heating elements 4 and 5 are not formed), the first heating element 4 and the second heating element 5 are not in contact with each other at the outer peripheral edge. Therefore, overheating can be reliably prevented.

  The present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the spirit of the present invention.

  For example, as shown in FIGS. 17 and 18, the wall portion 7 can be formed so as to surround the first heating element 4 at the outer peripheral edge portion of the first support portion 2. By forming the wall portion 7 in this way, the oil and water coming out of the article to be heated F can be blocked by the wall portion 7 by heating. As a result, the inside of the microwave oven can be prevented from becoming dirty. In addition, although this wall part 7 is not specifically limited, For example, it can form with paper, a nonwoven fabric, a woven fabric, sponge, urethane etc. It is more preferable that the wall portion 7 is made of a material that absorbs oil and moisture. Examples of materials that absorb oil and moisture include, for example, the paper, non-woven fabric, woven fabric, sponge, urethane and the like described above. However, other materials can absorb oil and moisture. If it exists, it can utilize as a material of the wall part 7. FIG. The height of the wall portion 7 varies depending on the object to be heated F, but is about 5 mm or less from the viewpoint of being able to fit the object to be heated F while damming up oil and moisture. It is preferable to do.

  Moreover, in the said embodiment, although the folds 21 and 31 formed in the 1st support part 2 and the 2nd support part 3 are one each, the crease | folds 21 and 31 in the 1st support part 2 or the 2nd support part 3 especially. The number of is not limited and can be two or more. By increasing the number of the folds 21 and 31, the heating elements 4 and 5 can be reliably brought into contact with the object to be heated F which has a curved surface, an uneven surface or the like and is not flat.

  Moreover, in the said embodiment, although the 1st support part 2 and the 2nd support part 3 became a planar view rectangular shape, it is not limited to this shape in particular, A planar view has a circular shape etc. Moreover, it can be set as the shape match | combined with the to-be-heated material F made into object.

  Moreover, in the said embodiment, although the outer peripheral edge part of the 1st support part 2 and the 2nd support part 3 is exposed, the 1st heat generating body 4 or the 2nd heat generating body 5 is made into the 1st support part 2 or the 1st, respectively. 2 The same size as that of the support portion 3 can be adopted so that the outer peripheral edge portions of the first support portion 2 and the second support portion 3 are not exposed. Further, as shown in FIG. 19, the right end portion of the first support portion 2 and the left end portion of the second support portion 3 (that is, the first support portion 2 and the second support portion 3 are connected to each other). It is also possible to expose only at least one of the end portion on the side opposite to the end portion where the portion 6 is located.

  In addition, as shown in FIG. 20, protrusions 8 can be formed at the four corners of the first support portion 2 and the second support portion 3. For example, the protrusion 8 can be formed by pressing (pressing) the first support 2 and the second support 3 in a convex shape from the back surfaces of the first support 2 and the second support 3. By forming the protrusions 8, it is possible to prevent the heating elements 4 and 5 supported by the support portions 2 and 3 from contacting each other. In addition, as long as this protrusion 8 does not contact the heat generating bodies 4 and 5, the position and number in which it forms are not specifically limited. For example, the protrusion 8 may be formed at the center of the long sides (relatively long outer peripheral sides) of the first support 2 and the second support 3.

  Moreover, in the said embodiment, although the 1st support part 2 and the 2nd support part 3 are connected via the connection part 6, the connection part 6 is omitted and the 1st support part 2 and the 2nd support part 3 Can also be linked directly. Moreover, the number of the coupling bodies 62 constituting the coupling portion 6 is not particularly limited. For example, as illustrated in FIG. 21, the first support portion 2 and the second support portion 3 can be coupled by three coupling bodies 62. .

  Further, the first support portion 2 and the second support portion 3 are engaged with the first support portion 2 and the second support portion 3 so that the heated object F is held between the first support portion 2 and the second support portion 3. It can also be formed on at least one of the support part 2 and the second support part 3. The configuration of the engaging portion is not particularly limited. For example, as shown in FIG. 22, a notch portion 32 formed in the second support portion 3 and a notch 23 in the first support portion 2. And the locking portion 22 formed by inserting the. By locking the locking portion 22 to the notch portion 32, it is possible to maintain a state in which the object to be heated F is sandwiched between the first support portion 2 and the second support portion 3.

  In addition, a configuration opposite to the above-described configuration, that is, a notch portion can be formed in the first support portion 2 and a locking portion can be formed in the second support portion. From the viewpoint that the workability of the locking work is good and the locking part is not easily detached during heating, the locking part 22 is formed in the first support part 2 and the notch part 32 is formed in the second support part 3. preferable. In addition, the number of these latching | locking parts 22 and the notch parts 32 is not specifically limited, For example, as shown in FIG. 22, you may form two or more engaging parts. In the heating auxiliary member 1 shown in FIG. 22, two cutout portions 32 and two locking portions 22 are formed as a plurality of engaging portions. In particular, when the size of the heating auxiliary member 1 is increased, it is preferable to form a plurality of engaging portions in order to more reliably engage the end portions of the first supporting portion 2 and the second supporting portion 3.

  Further, a fold line 33 (see FIG. 21) may be formed so as to surround the notch 32. By forming the fold line 33, the region surrounded by the fold line 33 of the second support part 3 can move slightly differently with respect to the other parts of the second support part 3, that is, has play. Can be made. Accordingly, it is possible to prevent the engagement between the locking portion 22 and the notch portion 32 during the heating of the article F to be heated in the microwave oven. Further, as shown in FIG. 21, cuts 34 may be formed at the four corners of the second support portion 3. By forming this notch 34, the movement of the second support portion 3 itself has a play (that is, the outer peripheral edge portion of the second support portion 3 can be freely deformed relatively to the center portion). Therefore, it is possible to prevent the second support portion 3 from returning from the state in which the object to be heated F is held to the opened state while the object to be heated F is being heated.

  Moreover, in the said embodiment, although the magnitude | size and shape of the 1st heat generating body 4 and the 2nd heat generating body 5 were made the same, it is not limited to this in particular, The 1st heat generating body 4 and the 2nd heat generating body 5 are the same. The size and shape can be different. For example, by making the width of the second heating element 5 (width in the left-right direction in FIG. 13) shorter than the width of the first heating element 4 (width in the left-right direction in FIG. 13), It can comprise so that the 2nd heat generating body 5 may become difficult to contact. Although not particularly limited, the width of the second heating element 5 at this time can be about 5 mm shorter than the width of the first heating element 4.

  Further, as shown in FIG. 22, the flaps 9 can be formed on the upper outer peripheral edge and the lower outer peripheral edge of the second support portion 3. Each of the flaps 9 is defined by a notch 35 and a fold line 36, and is configured to be valley-folded along the fold line 36. Then, when the connecting portion 6 is bent against the crease 61 and the second support portion 3 is disposed above the first support portion 2 to hold the object to be heated F, the flap 9 is moved to the first support portion. The gap formed between the first support part 2 and the second support part 3 can be filled with the flap 9 by bending it about 90 degrees to the second side. Thereby, even when oil or water is scattered from the article to be heated F during heating, the oil can be received by the flap 9 and the inside of the microwave oven can be prevented from being soiled. The flap 9 can be formed on the first support portion 2 with the same configuration, or can be formed on both the first support portion 2 and the second support portion 3. In FIG. 22, the crease 36 is formed by a perforation. However, the crease 36 is not particularly limited as long as the flap 9 can be valley-folded, and may be formed by, for example, a folding line.

  In addition, as shown in FIG. 22, arc-shaped folds 37 can be formed so as to surround the four corners of the first support portion 2 and the second support portion 3, respectively. As a result, the folds 37 at the four corners act as reinforcing portions, so that the first support portion 2 and the second support portion 3 can be prevented from being deformed and warped during heating. In addition, since the 1st support part 2 does not generate | occur | produce much curvature by the to-be-heated material F being mounted, you may form the crease | fold 37 only in the 2nd support part 3, as shown in FIG.

  Moreover, in the said embodiment, the 1st support part 2 and the 2nd support part 3 are the 2nd above the state which expand | deployed as shown in FIG. 13, and the 1st support part 2 as shown in FIG. Although the two states, the state in which the support part 3 is disposed, can be taken, the second support part 3 is always disposed above the first support part 2, that is, in a form in which the support part 3 is not deployed. It is also possible to adopt the form. As such an example, the bag-shaped heating auxiliary member 1 as shown in FIGS. 23 and 24 can be mentioned. The bag-like heating auxiliary member 1 includes a first support 2 that supports the first heating element 4 and a second support 3 that supports the second heating element 5. The 1st support part 2 and the 2nd support part 3 are forming the bag shape by leaving the outer periphery of one side, and connecting the outer periphery of the remaining 3 sides. In addition, the part which is not connected comprises the opening part 10 (refer FIG. 24) for putting the to-be-heated material F in the heating auxiliary member 1. FIG. FIG. 25 is a developed view of the bag-like heating auxiliary member 1. As shown in FIG. 25, the first heating element 4 and the second heating element 5 come into contact with each other and are overheated. In order to prevent this, it is preferable that the first heating element 4 and the second heating element 5 are not formed on the outer peripheral edges of the first support part 2 and the second support part 3. In addition, although the margin part 24 for forming a bag shape is formed in the outer periphery of the 1st support part 2, the margin part 24 may be formed in the 2nd support part 3. FIG.

  Further, as shown in FIG. 23, in a state where the object to be heated F is not put in the heating auxiliary member 1, the distance between the first support part 2 and the second support part 3 is the distance of the object to be heated F. It is preferable that the thickness is smaller than the thickness. Then, as shown in FIG. 24, when the article to be heated F is placed inside the heating auxiliary member 1 and the article to be heated F is placed on the first heating element 4, the first heating element 4 and the second heating element. The 2nd support part 3 moves to the direction away from the 1st support part 2, keeping the state which 5 contacted the to-be-heated material F. FIG. As described above, even when the heating auxiliary member 1 is formed in a bag shape, the first heating element 4 and the second heating element 5 can be brought into contact with the upper and lower surfaces of the heating object F. Both sides can be burnt at the same time, and the same effect as in the above embodiment can be obtained.

  In addition, the said modification is an example which shows that the same effect as the said embodiment can be acquired even if it is the heating auxiliary member 1 which will not be in the expand | deployed state, If at least one part of an outer periphery is connected There is no particular limitation on making the heating auxiliary member 1 into a bag shape. For example, by not connecting the outer peripheral edge on the opposite side of the outer peripheral edge where the opening 10 in FIG. 24 is formed, another opening 10 is formed on the outer peripheral edge on the opposite side, thereby forming a cylindrical heating. It can be an auxiliary member. In addition, it is preferable to make the heating auxiliary member 1 into a bag shape from the viewpoint of preventing the oil and water from the object to be heated F from flowing out or scattering into the microwave oven. Moreover, the planar shape of the 1st support part 2 and the 2nd support part 3 is not limited to a rectangular shape, A various shape is employable.

  In addition, as shown in FIG. 26, a pair of edge portions facing each other in the outer peripheral edge portion when the first support portion 2 and the second support portion 3 are connected (for example, when the first support portion 2 is viewed in a plan view). ) Can also be formed with the stretchable part 11. The stretchable part 11 can be formed, for example, by bending the connecting part once inward to form a bellows. By forming the expansion / contraction part 11 in this way, when the article to be heated F is placed in the heating auxiliary member 1, the expansion / contraction part 11 extends so that the entire second support part 3 is relative to the first support part 2. It is possible to move upward while maintaining a substantially parallel state. For this reason, the 1st heat generating body 4 and the 2nd heat generating body 5 can be made to contact the whole surface of the to-be-heated material F equally.

  Further, as shown in FIG. 27, the first support part 2, the second support part 3, the first heating element 4 and the second heating element 5 can be sized so that a plurality of objects to be heated F can be placed thereon. . Thereby, it becomes possible to heat several to-be-heated material F simultaneously. In this case, one heating element (the first heating element 4 or the second heating element 5) may be attached to each first support part 2 or second support part 3 as in the above-described embodiment. In addition, two or more heating elements may be attached to one support part (for example, the first support part 2).

  The heating auxiliary member 1 in each of the above embodiments has the uneven shape as described above formed in the first heating element 4 and the second heating element 5, and thus can be used a plurality of times without deterioration of its function. . Moreover, the fold lines 21 and 31 formed in the first support part 2 and the second support part 3 of each of the above embodiments can be omitted.

(Embodiment 3)
28 to 30 show the appearance of a microwave heating container 101 (hereinafter simply referred to as “heating container 101”) as a heating auxiliary member according to an embodiment of the present invention. This heating container 101 is for containing a food as an object to be heated in a container and cooking the food in a microwave oven (not shown). The food is cooked once or a plurality of times. After that, it can be disposable.

  The heating container 101 in the illustrated example has a tray shape with an open top surface, and includes a bottom surface portion 102 that can support food, and a side surface portion 103 that rises from the periphery of the bottom surface portion 102. The bottom surface portion 102 is formed in a substantially circular shape in plan view, thereby making the contour shape of the heating container 101 smooth without a corner portion. The microwave emitted from the magnetron (not shown) of the microwave oven has a characteristic that the microwave is concentrated at the corner when the outline shape of the container is a corner with a corner. Becomes preferentially irradiated. Therefore, in this embodiment, by making the bottom surface portion 102 into a circular shape, microwaves are not concentrated on the corner portions, and the bottom surface portion 102 and the side surface portion 103 of the heating container 101 are uniformly irradiated with microwaves. I am doing so. As a result, although the details will be described later, the bottom surface portion 102 and the side surface portion 103 receive heat from the microwaves to generate heat uniformly.

  In addition to the circular shape, the shape of the bottom surface portion 102 may be various shapes as long as it has a substantially circular shape without corners, such as an oval shape, an elliptical shape, or a polygonal shape with rounded corners. it can. Further, in the present embodiment, the bottom surface portion 102 has a substantially circular shape without corners so that the bottom surface portion 102 and the side surface portion 103 are uniformly irradiated with microwaves, but the present invention is not necessarily limited thereto. The bottom surface portion 102 may be formed in a square shape.

  The side surface portion 103 is formed integrally with the bottom surface portion 102 and forms a peripheral wall having a predetermined height that surrounds the bottom surface portion 102. Thus, when non-solid / semi-solid foods (fluids having fluidity) such as eggs or foodstuffs that obtain fluidity by heating such as cheese or butter are contained in the heating container 101 However, the food is prevented from spilling from the heating container 101.

  The side surface portion 103 has a plurality of crest portions 130 protruding radially outward from the upper end to the lower end and a plurality of trough portions 131 recessed radially inward in the circumferential direction of the side surface portion 103 over the entire circumference of the side surface portion 103. Are provided alternately and repeatedly. The crest portion 130 and the trough portion 131 are formed so as to be wider toward the top, and the side surface portion 103 has a transverse cross section (horizontal cross section) formed in a wave shape.

  The side surface portion 103 is provided with a plurality of the crest portions 130 and the trough portions 131 described above, and the surface thereof is uneven, so that the surface area is larger than the case where the surface is smooth. As a result, as will be described later, since the heat transfer area of the side surface portion 103 that generates heat by microwave irradiation and heats the food from the side by heat conduction is increased, the heating power to the food is increased. Furthermore, since the side surface portion 103 has a large surface area after heating, the generated heat is efficiently dissipated, and the temperature is lowered relatively quickly. In addition, since the plurality of peak portions 130 and valley portions 131 reinforce the side surface portion 103, the strength of the heating container 101 is improved, so that the shape retaining property is excellent, and the food (especially, the food having fluidity). ) Can be stored in a stable state.

  The pitch of the crests 130 that circulate, that is, the interval between two adjacent crests 130 is preferably in the range of 4/10 cm to 20/10 cm, and is between 8/10 cm and 17/10/10 cm. The following is more preferable. If the pitch is less than 4/10 cm, the surface area is not so different from the case where the surface of the side surface portion 103 is flat, so the heating power to the food does not increase so much and the side surface portion 103 is not sufficiently reinforced. .

  Further, the height difference h (see FIG. 29) between the peak portion 130 and the valley portion 131 is preferably in the range of 3 mm to 10 mm. The reason for the above numerical range is as follows. That is, if the height difference h is less than 3 mm, the surface unevenness is too small, and the surface area does not change so much from the case where the surface of the side surface portion 103 is flat. This is because the reinforcement of 103 is not sufficient. On the other hand, if the height difference h exceeds 10 mm, the unevenness of the surface becomes too large, which is not practical.

  The bottom surface portion 102 and the side surface portion 103 are provided with a conductive material layer 104 that generates heat when irradiated with microwaves on a surface in contact with food. This conductive material layer 104 generates heat during heating with a microwave oven to a high temperature (about 170 ° C. to 250 ° C.), similar to the Al vapor deposition layer 12 of the heating element 16 in Embodiment 1 of the present invention described above. Become. As a result, the food material can be cooked by heat conduction, for example, by heating the food material from below and from the side and, if necessary, burning or baking the surface of the food material in contact therewith. The heating container 101 is composed of a heating element including the conductive material layer 104. The pressure-bonding area ratio in the heating element is 20% or more and 80% or less. Therefore, similar to the heating auxiliary member in Embodiment 1 of the present invention, the heating container 101 that can be repeatedly used and has excellent durability can be obtained.

  Here, the size of the heating container 101 (the diameter d of the bottom surface portion 102) is not particularly limited, and can be set to various sizes depending on the application. For example, in the case where the heating container 101 is used in a compact manner, for example, in a lunch box to provide food, the diameter d of the bottom surface portion 102 is preferably about 3 cm to 5 cm. In addition, when used for making a dish such as dinner, the diameter d of the bottom surface portion 102 is preferably about 5 cm to 25 cm. However, if the diameter d of the bottom surface portion 102 is too small (for example, smaller than 3 cm), the heating container 101 is too small and cooking is difficult. On the other hand, if the diameter d of the bottom surface portion 102 is too large (for example, exceeding 25 cm), there is a possibility that the shape retaining property of the heating container 101 is deteriorated and easily deformed.

  Further, the depth of the heating container 101, that is, the height H of the side surface portion 103 (see FIG. 30) is not particularly limited, and can be set to various sizes depending on the application. 1 cm or more is preferable. If the height H is less than 1 cm, the food contained in the heating container 101 (particularly, the food having fluidity) is spilled and is difficult to cook. Furthermore, when the height H of the side surface portion 103 is low, as will be described later, the side surface portion 103 hardly exerts a blocking effect for preventing the microwave from entering the heating container 101, and the microwave irradiation to the foodstuff is not performed. This is because the amount cannot be suppressed. On the other hand, the higher the height H is, the more preferable is the microwave blocking effect by the side surface portion 103. However, when storing in a lunch box or the like, it is necessary to suppress the height to about 2 cm to 4 cm at the maximum. . In other applications, if the height H of the side surface portion 103 is too high (for example, exceeding 10 cm), the size may become too large (bulky) and difficult to carry.

  Considering the above, the depth of the heating container 101 with respect to the size of the heating container 101, specifically, the outer peripheral length of the bottom surface part 102 (π × d in the present embodiment) (height H of the side surface part 103). Is preferably in the range of 1/60 to 3/4, and more preferably in the range of 1/20 to 1/2. For example, the dimensions of the heating container 101 are such that the diameter d (shown in FIG. 29) of the lower surface (bottom surface portion 102) of the heating container 101 is 9 cm, and the diameter D (shown in FIG. 30) of the upper surface is 10.5 cm. The height H (shown in FIG. 30) of the side surface portion 103 may be set to 4 cm, and the height difference h (shown in FIG. 29) of the peak portion 130 and the valley portion 131 may be set to 4 mm.

  In the present embodiment, the above-described bottom surface portion 102 and side surface portion 103 are formed on at least one surface of a flat sheet material (paper 18 in FIG. 3) made of paper, similarly to the structure shown in FIG. 3 in the first embodiment. And a single heating element 16 (heating sheet) formed by laminating a conductive material layer 104 and a resin layer 13 which is a heat-resistant film layer protecting the conductive material layer 104 with an adhesive 15 interposed therebetween. Is done. The heat generating body 16 has a concavo-convex shape formed on the surface in advance. And as shown in Embodiment 1 of this invention, the uneven | corrugated shape is formed so that a crimping | compression-bonding area ratio may be 20% or more and 80% or less. Therefore, the heating container 101 having such a configuration can provide the same effects as those of the heating auxiliary member 1 shown in the first embodiment of the present invention. Then, the heating element 16 having a predetermined size cut into a circle is folded along the fold line 110 (shown in FIG. 29) so that the paper 18 becomes the outermost surface, and the side part 103 is folded around the bottom surface part 102. Get up and running. Furthermore, it is integrally formed over the entire circumference of the side surface portion 103 by alternately repeating mountain folds and valley folds along outer and inner folds 111 and 112 (shown in FIG. 29). For such molding, for example, a press machine or the like can be used.

Sheet material constituting the material and thickness of the paper (base member corresponding to the paper 18 in FIG. 3) is not particularly limited, paper thickness basis weight 20g / m ² ~120g / m ² about It is preferred to use thin paper. By using thin paper with a small thickness, the heat transmitted from the conductive material layer 104 is effectively dissipated to the outside air after the cooking by the microwave oven is completed. It is possible to promote an early decrease in the temperature of the portion 103).

  In the present embodiment, the heating container 101 is manufactured by molding the heating element 16 (see FIG. 3) itself in which the concavo-convex portions are formed in advance. However, the present invention is not limited to this. After producing a container (not shown) composed of a conductive layer 104 such as an aluminum thin film by vapor deposition on a resin layer 13 which is a heat-resistant film layer produced separately, a heat generating sheet (FIG. (Not shown) may be cut into a predetermined shape and attached to the bottom surface or side surface of the container by bonding or the like to produce the heating container 101.

  Next, a method of cooking food using the heating container 101 having the above-described configuration will be described. First, various ingredients constituting a desired dish are placed on the bottom surface portion 102 of the heating container 101. At that time, the ingredients to be burnt or burnt are placed directly on the bottom surface 102.

  And the heating container 101 which accommodated the foodstuff is mounted in a microwave oven, and the heating by a microwave oven is performed for predetermined time. When heating by the microwave oven is performed in this manner, the microwaves emitted from the microwave oven are irradiated to the foodstuff and the heating container 101. Thereby, a foodstuff is heated from the inside by microwave irradiation. Further, the conductive material layer 104 provided on the bottom surface portion 102 and the side surface portion 103 of the heating container 101 receives heat from the microwaves and generates heat, resulting in a high temperature. It is also heated from the direction. At this time, since the conductive material layer 104 directly heats the surface of the food material in contact with the conductive material layer 104, the food material is burnt or burnt as desired.

  Here, among the microwaves irradiated to the heating container 101 from the microwave oven, the microwaves that have reached the side surface portion 103 from the outside are reflected, and the intrusion into the heating container 101 (irradiation of food) is blocked. . In addition, microwaves that reach the side surface portion 103 from the inside are reflected, but the surface of the side surface portion 103 (conductive material layer 104) is formed to be uneven by a plurality of peak portions 130 and valley portions 131, and further heated. Since a small uneven portion is also formed on the surface of the heating element constituting the container 101, the microwave is reflected on the surface of the side surface portion 103 (conductive material layer 104) and diffuses in all directions. Compared with the case where is formed smoothly, the amount of microwaves irradiated to the foodstuff decreases.

  As described above, in the heating container 101 of the present embodiment, the conductive material layer 104 is provided on the side surface portion 103 and the side surface portion 103 is formed in a wave shape in cross section, thereby directly acting on the food. The food can be cooked in a state where the amount of microwaves, that is, internal heating of the food by microwave irradiation is suppressed. Therefore, the suppression effect can reduce the amount of transpiration of moisture inside the food material, and as a result, the food material after cooking is given a plump and soft texture.

  Also, for example, after putting butter on the bottom surface 102 of the heating container 101, one potato ground into two well-stirred eggs and 100 ml of milk are poured into the heating container 101 and about 600 W is added. You may use the heating container 101 by this invention for the cooking which heated with the microwave oven for 4 minutes. In this case, the egg omelet cooked in the heating container 101 of the present embodiment is pleasingly tasty and can feel a soft texture. Thus, when the heating container 101 of this embodiment is used, it is possible to realize a state close to heating by a conventional frying pan or oven. In addition, the heating container 101 used for such cooking is such that the diameter d (shown in FIG. 29) of the lower surface (bottom surface portion 102) of the heating container 101 is 12.4 cm and the upper surface diameter D (FIG. 30). Is set to 15.3 cm, the height H of the side surface portion 103 (shown in FIG. 30) is set to 4 cm, and the height difference h (shown in FIG. 29) of the peak portion 130 and the valley portion 131 is set to 4 mm. It may be.

  Further, in the heating container 101 of the present embodiment, since the side surface portion 103 has an uneven shape, the surface area of the side surface portion 103 increases, and therefore, the heat transfer area by the conductive material layer 104 increases during heating. In addition, the heating power to the food is increased. Therefore, it is possible to pass the heat firmly to the ingredients. On the other hand, after cooking, since the conductive material layer 104 has a large surface area, the generated heat is efficiently dissipated and the temperature is lowered relatively quickly. In addition, since the paper 18 as the sheet material is made of thin paper having a small thickness, the heat transferred from the conductive material layer 104 is effectively dissipated without being accumulated. Therefore, in a short time after cooking, the side surface 103 can be picked by hand without worrying about burns and the heating container 101 can be carried.

  As mentioned above, although one Embodiment of this invention was explained in full detail, the specific aspect of this invention is not limited to above-described embodiment. For example, in the present embodiment, the heating container 101 has an upper surface opened, and microwaves can be applied to the food from the upper surface. The heating container 101 is configured to further include a removable lid that closes the upper surface opening. May be. As the lid, for example, a lid having an open bottom surface and a substantially circular lid body portion covering the food material and a hanging wall portion hanging from the periphery of the lid body portion may be used. Similar to the side surface portion 103 of the heating container 101 described above, the drooping wall portion may be formed in a cross-sectional corrugated shape in which a plurality of peaks and valleys are alternately repeated along the circumferential direction over the entire circumference. In the lid portion and the hanging wall portion, a conductive material layer 104 that generates heat upon irradiation with microwaves may be provided on the surface facing the food. The configuration and manufacturing method of the lid can be the same as the configuration and manufacturing method of the heating container 101 described above. Further, the size of the lid may be set to be approximately the same as or slightly larger than the size of the heating container 101.

  When the lid is used in this way, the upper surface opening of the heating container 101 is covered with the lid, and therefore, the microwave irradiated from above the food is reflected by the conductive material layer of the lid, so that the heating container 101 enters the heating container 101. Intrusion is suppressed. Therefore, it is possible to substantially block the microwave irradiation to the food material. And since the conductive material layer provided on the lid part and the drooping wall part of the lid generates heat due to the microwave irradiation and becomes high temperature, the heat conduction causes the food not only from below and from the side, but also from above. Will also be heated. As a result, since the food is heated not by internal heating by microwave irradiation but by external heating by heat conduction from the conductive material layer 104, the amount of moisture transpiration inside the food can be reduced, and more conventional It is possible to realize a state close to heating by a frying pan or an oven.

Hereinafter, the actual form 4 of the heating auxiliary member according to the present invention will be described. 31 to 33 show the appearance of a microwave heating container 201 (hereinafter simply referred to as “heating container 201”) as a heating auxiliary member according to an embodiment of the present invention. The heating container 201 is configured by the heating element 16 disclosed in the first embodiment of the present invention, and contains the food in the container and cooks the food in a microwave oven (not shown). Therefore, after the cooking of the food is performed a plurality of times, it can be disposable. The heat generating body 16 has a concavo-convex shape formed on the surface in advance. And as shown in Embodiment 1 of this invention, the uneven | corrugated shape is formed so that a crimping | compression-bonding area ratio may be 20% or more and 80% or less. Therefore, the heating container 201 having such a configuration can provide the same effects as those of the heating auxiliary member 1 shown in the first embodiment of the present invention.

  The heating container 201 shown in FIG. 31 basically has the same configuration as that of the heating container 101 in the third embodiment of the present invention, but the outer shape thereof is different. That is, in the heating container 201 shown in FIGS. 31 to 33, the heating element has a tray shape with the top opened as shown in FIG. 31, and the bottom 202 on which the food can be placed and the periphery of the bottom 202. And a side wall portion 203 that rises. The bottom portion 202 is formed in a substantially bowl shape in which a periphery is formed by a linear portion 202a and an arc-shaped portion 202b in plan view. Thereby, the outline shape of the heating container 201 is made smooth with no corners. In addition to the bowl shape, the shape of the bottom portion 202 assumes a variety of shapes as long as the periphery is formed by a linear portion and an arc-shaped portion, such as a polygonal shape with a rounded corner portion. it can.

  The side wall portion 203 is formed integrally with the bottom portion 202 so as to be raised at the periphery of the bottom portion 202 and surround the bottom portion 202, and forms a peripheral wall having a predetermined height that surrounds the bottom portion 202. Thereby, when a non-solid or semi-solid food material (fluid food material) that does not have solidity such as an egg or a food material that obtains fluidity by heating such as cheese or butter is contained in the heating container 201 However, the food material is prevented from spilling from the heating container 201.

  As shown in FIG. 32, the side wall portion 203 has a plurality of crest portions 230 a and 230 b protruding outward and a plurality of trough portions 231 a and 231 b that are recessed inward, which are alternately repeated along the periphery of the bottom portion 202. Is formed. As shown in FIG. 33, the arc region 203b rising at the arc-shaped portion 202b of the bottom portion 202 is formed in a corrugated shape in the range from one end to the other end adjacent to the bottom portion 202, that is, the entire region. The corrugated shape in the arc region 203b is formed so as to be wider in the direction along the periphery of the bottom portion 202 as it is farther from the bottom portion 202, and the side wall portion 203 has a transverse cross section (horizontal direction) substantially parallel to the bottom portion 202. (Cross section) is formed in a wave shape.

  On the other hand, the straight region 203a that rises at the straight portion 202a of the bottom portion 202 is formed in a corrugated plate shape so that the crest portion 230a and the trough portion 231a have substantially the same width regardless of the distance from the bottom portion 202. At this time, the arrangement pitch of the peak portions 230a of the linear region 203a is formed to be wider than the arrangement pitch of the peak portions 230a of the arc region 203b. Further, the straight line region 203a is formed in a corrugated shape from a position away from the bottom 202 by a distance L1, that is, from a position farther from the bottom 202 than the arc region 203b. At this time, in the straight line region 203a, a range of a distance L1 between the bottom portion 202 and the position formed in the corrugated plate shape is formed in a substantially flat plate shape. Here, the straight line region 203a according to the present embodiment has a portion formed in a substantially flat plate shape, that is, a distance L1 between one end adjacent to the bottom portion 202 and a region formed in a corrugated plate shape. The distance L2 from one end to the other end adjacent to the bottom 202 is preferably 1/10 or more and 4/5 or less, and more preferably 1/4 or more and 3/4 or less. In the present embodiment, for example, the distance L1 is 13 mm and the distance L2 is 37 mm.

  Since the side wall portion 203 is provided with a plurality of the above-described peak portions 230a and 230b and valley portions 231a and 231b, and the surface thereof is uneven as in the heating container 101 shown in the third embodiment, Compared with the case where the surface is smooth, the surface area is large. As a result, as will be described later, since the heat transfer area of the side wall portion 203 that generates heat by microwave irradiation and heats the food from the side by heat conduction is increased, the heating power of the food is increased. Further, after heating, the side wall portion 203 has a large surface area, so that the generated heat is efficiently dissipated and the temperature decreases relatively quickly. In addition, since the plurality of peak portions 230a and 230b and valley portions 231a and 231b reinforce the side wall portion 203, the strength of the heating container 201 is improved, so that the plasticity is excellent. Therefore, when foodstuffs (especially foodstuffs having fluidity) are accommodated, the foodstuffs can be held in a stable state.

  The arrangement pitch of the crests 230b in the arc region 203b, that is, the interval between the vertices of two adjacent crests 230b is preferably in the range of 4 / 10cm to 20 / 10cm, and 8 / 10cm or more. More preferably, the number is 17 pieces / 10 cm or less. On the other hand, the pitch of the crests 230b that circulate in the straight region 203a, that is, the interval between the vertices of two adjacent crests 230b is preferably in the range of 4 / 10cm to 10 / 10cm, It is more preferable that the number is / 10 cm or more and 17 pieces / 10 cm or less.

  In addition, the height difference hb between the peak portion 230b and the valley portion 231b in the arc region 203b is preferably in the range of 0.1 mm to 20 mm, and more preferably in the range of 3 mm to 10 mm. On the other hand, the height difference ha of the peak portion 230b and the valley portion 231b in the linear region 203a is preferably in the range of 0.1 mm to 20 mm, and more preferably in the range of 3 mm to 10 mm.

  The cross-sectional structure and planar shape of the bottom portion 202 and the side wall portion 203 are basically the same as those of the heating container 101 shown in the third embodiment.

  Here, in the heating container 201 in the present embodiment, the radius of curvature R of the arc-shaped portion 202b of the bottom portion 202 is, for example, 40 mm, and the length L3 in the longitudinal direction of the bottom portion 202 is, for example, 155 mm. The thickness is not particularly limited, and can be set to various sizes depending on the application.

  Hereinafter, a method for manufacturing the heating container 201 using a press machine will be described. First, a plurality of heating elements 16 (heating sheets) are arranged in a stacked manner between a male die and a female die of a press machine. At this time, for example, 50 heat generating sheets are arranged in an overlapping manner.

  Next, press molding is performed with a plurality of heat generating sheets stacked between the male mold and the female mold. The male mold and the female mold are formed in the same shape as each of the inner surface and the outer surface of the heating container 201 whose surface in contact with the heat generating sheet is completed. That is, in the male mold and the female mold, the corrugated portion of the straight region 203a and the surface in contact with the arc region 203b are formed in a corrugated shape, and the substantially flat plate portion of the straight region 203a and the bottom portion 202 are formed. The contacting surface is formed in a substantially planar shape. These male molds and female molds are spaced from each other by the number of heat generating sheets that are generally stacked in a state where the heat generating sheets are completely sandwiched.

  And the heat-formed sheet | seat press-molded is taken out from a press machine in the state in which the some heating container 201 overlapped.

  In the present embodiment, the side wall 203 is formed in a corrugated shape from a position farther from the bottom 202 than the arc region 203b where the straight region 203a rising at the straight portion 202a of the bottom 202 rises at the arc-shaped portion 202b. . As a result, the heating container 201 can improve the rigidity of the straight region 203a by the corrugated portion, and can make it difficult for tensile stress to occur due to the non-corrugated portion of the straight region 203a during pressing. For this reason, the heating container 201 is formed by bending a heat generating sheet, and even if it is a container having a linear portion 202a at the bottom, it is difficult to break during press working or the like, and is difficult to be distorted during use. In addition, since the heating container 201 is difficult to break at the time of pressing, a large number of heat generating sheets can be stacked and pressed together, and the productivity of the heating container 201 can be improved.

  As mentioned above, although this invention was demonstrated based on embodiment, this invention is not limited to this. For example, in the present embodiment, the heating container 201 is manufactured by forming a heat generating sheet in which an adhesive layer, a conductive material layer 204, and a heat-resistant film layer are laminated on one side of a paper sheet. However, the present invention is not limited to this, and other methods exemplified in Embodiment 3 (for example, after a container (not shown) made of paper or the like is manufactured, vapor deposition is performed on a separately manufactured heat-resistant film layer. A heating container (not shown) having a structure in which a conductive material layer 204 such as an aluminum thin film is formed by cutting into a predetermined shape and pasting to the bottom or side of the container by bonding or the like is provided. 201) may be employed.

(Embodiment 5)
A heating container 301 as a heating auxiliary member according to the present invention will be described with reference to FIGS. 34 to 38. The heating container 301 basically has the same configuration as that of the heating container 201 shown in the fourth embodiment of the present invention. That is, the heating container 301 is configured by the heating element 16 disclosed in the first embodiment of the present invention. The heating container 301 accommodates food in the container and heats the food in a microwave oven (not shown). It is for cooking, and can be disposable after the food is cooked multiple times. The heat generating body 16 has a concavo-convex shape formed on the surface in advance. And as shown in Embodiment 1 of this invention, the uneven | corrugated shape is formed so that a crimping | compression-bonding area ratio may be 20% or more and 80% or less. Therefore, the heating container 301 having such a configuration can provide the same effects as those of the heating auxiliary member 1 shown in the first embodiment of the present invention.

  The illustrated heating container 301 has a tray shape with an open upper surface, and includes a bottom portion 302 capable of supporting foodstuffs, and a side wall portion 303 rising from the periphery of the bottom portion 302. The bottom portion 302 is formed in a generally ceremonial shape having a longitudinal direction in which a substantially straight line and a curved line are connected to each other in plan view, thereby making the contour shape of the heating container 301 smooth without a corner portion. For this reason, in this embodiment, the bottom 302 is shaped like a bowl to avoid the problem of microwave concentration at the corners, similar to the heating container 201 in the fourth embodiment. On the other hand, the bowl shape is formed by connecting a linear portion 302a and a circular arc (semicircle) portion 302b as a curve, and from each point of the circular arc portion 302b to the center Ca of the heating container 301. The distance Lb is equal to or longer than the distance La from each point of the linear portion 302a to the center Ca of the heating container 301. For this reason, when it sees in the whole bottom part of the heating container 301, a difference will arise in the grade of the heating from the side wall part 303. FIG. Specifically, in the vicinity of the center Cb of the arc, the heating is performed in such a manner as to be surrounded by the arc-shaped side wall 303 in addition to the heating from the bottom 302. On the other hand, in the region of the center Ca of the heating container 301, heating is performed from the bottom portion 302 and the side wall portion 303 of the two linear portions 302a, but since it is far from the arc-shaped portion 302b, the region of the center Cb of the arc is In comparison, the degree of heating is low. From the above, in the bowl-shaped heating container 301, a high heating effect is obtained in both end regions in the longitudinal direction of the heating container 301, and conversely, the heating effect is reduced in the central region, so-called heating unevenness is realized. be able to.

  In addition, the straight line that forms a part of the planar shape of the bottom is not limited to a straight line in a strict sense, but includes a line that can be identified almost as a straight line. For this reason, the planar shape of the bottom is not strictly limited to the above-described saddle shape (combination of a straight line and a curve), but is a combination of a line and a curve that can be identified as almost a straight line. For example, an elliptical shape or other oval shapes may be used.

The side wall portion 303 is formed integrally with the bottom portion 302 and forms a peripheral wall having a predetermined height that surrounds the bottom portion 302. Thereby, non-solid / semi-solid foods (fluids that have no fluidity) such as eggs or foodstuffs that obtain fluidity by heating such as cheese or butter are contained in the heating container 301. However, the food material is prevented from spilling from the heating container 301.
The side wall portion 303 includes a plurality of peak portions 330 a and 330 b that protrude radially outward from the upper end to the lower end thereof and a plurality of valley portions 331 a and 331 b that are recessed radially inward over the entire circumference of the side wall portion 303. Are provided alternately and repeatedly along the circumferential direction. The crest portion 330b and the trough portion 331b in the arc-shaped portion 302b are formed so as to be wider toward the upper side, and the side wall portion 303 has a transverse cross section (horizontal cross section) formed in a wave shape. On the other hand, the peak part 330a and the valley part 331a in the linear part 302a are formed substantially in parallel from the bottom part toward the upper end.

  As in the case of the fourth embodiment, the side wall portion 303 is provided with a plurality of the above-described peak portions 330a and 330b and valley portions 331a and 331b, and the surface thereof is uneven, so that the surface is smooth. Compared with the case, the surface area is large. As a result, as will be described later, since the heat transfer area of the side wall portion 303 that generates heat by microwave irradiation and heats the food from the side by heat conduction is increased, the heating power of the food is increased. Further, after heating, the side wall portion 303 has a large surface area, so that the generated heat is efficiently dissipated and the temperature is lowered relatively quickly.

  In addition, since the plurality of peak portions 330a and 330b and valley portions 331a and 331b reinforce the side wall portion 303, the strength of the heating container 301 is improved, so that the shape retaining property is excellent, and the food (especially, the flow When the foodstuff having the property is accommodated, the foodstuff can be held in a stable state.

  In the embodiment shown in FIG. 34, the pitches of the peak portions 330a and 330b and the valley portions 331a and 331b are changed between the linear portion 302a and the arc-shaped portion 302b. That is, the pitch of the linear portion 302a is larger than the pitch of the arc-shaped portion 302b. This is because the heat generation at the side wall portion 303 is increased by increasing the surface area of the arc-shaped portion 302b, and as a result, the heating power for the foodstuff is improved. At the same time, since the area of the side wall portion 303 of the arc-shaped portion 302b is large, microwaves irradiated from the outside are blocked to some extent by the side wall portion 303, and the amount of direct irradiation to the food can be reduced. This leads to suppression of excessive loss of moisture from the food.

  Similarly to the heating container in the fourth embodiment of the present invention, the bottom 302 and the side wall 303 are provided with a conductive material layer that generates heat upon irradiation with microwaves on the surface in contact with the foodstuff. . This conductive material layer generates heat when heated by a microwave oven and becomes a high temperature (about 170 ° C. to 250 ° C.), so that the food is heated from below and from the side by heat conduction. It is provided for cooking the food by heating the surface of the food that comes into contact with the food, such as by burning or baking.

  Here, the size of the heating container 301 (the length of the linear portion of the bottom portion 302 and the diameter d of the arc-shaped portion) is not particularly limited, and can be set to various sizes depending on the application. it can. For example, in the case where the heating container 301 is used for serving dishes by storing it in a lunch box or the like, it is preferable that the length of the bowl-shaped longitudinal direction is about 3 cm to 5 cm. In addition, when used to make a single dish such as dinner, it will be cooked with more kinds of ingredients, so the length of the bowl shape in the longitudinal direction should be about 5 cm to 25 cm Is preferred. However, if the length of the bottom portion 302 in the longitudinal direction is too short (for example, smaller than 3 cm), the heating container 301 is too small to be cooked. On the other hand, if the length of the bottom portion 302 in the longitudinal direction is too long (for example, If it exceeds 25 cm), there is a possibility that the shape retention of the heating container 301 will be reduced and it will be easily deformed. In this case, it is more preferable that the ratio of the dimension in the longitudinal direction and the dimension in the direction perpendicular to the longitudinal direction is in the range of 4: 1 to 3: 2 from the viewpoint of realizing appropriate heating unevenness.

  Further, the depth of the heating container 301, that is, the height H of the side wall portion 303 is not particularly limited, and can be set to various sizes depending on the application, but is preferably 1 cm or more. If the height H is less than 1 cm, the ingredients contained in the heating container 301 (particularly, the ingredients having fluidity) are spilled and difficult to cook, and the side wall 303 has a low height H, which will be described later. As described above, this is because the side wall portion 303 hardly exhibits a blocking effect for preventing microwaves from entering the heating container 301, and the amount of microwaves irradiated to the food material cannot be suppressed. On the other hand, the higher the height H is, the more preferable is the microwave blocking effect by the side wall portion 303. However, when storing in a lunch box or the like, it is necessary to suppress the height to about 2 cm to 4 cm at the maximum. . In other applications, if the height H of the side wall portion 303 is too high (for example, exceeding 10 cm), it may be bulky and difficult to carry.

In consideration of the above, the depth of the heating container 301 with respect to the size of the heating container 301, specifically, the outer peripheral length of the bottom 302 (in this embodiment, linear portion length × 2 + arc-shaped portion length × 2). The ratio of (height H of the side wall portion 303) is preferably in the range of 1: 100 to 3:10.
In addition, since the heating container 301 according to the present embodiment is formed by the heating element 16 (heating sheet) using thin paper, by cutting and pressing a large number of heating sheets in a stacked state, the number of processes is reduced. A large number of heating containers 301 can be manufactured. This is an advantage that is obtained due to the simple shape of the heating container 301 including the bottom portion 302 and the side wall portion 303.

  Next, a method of cooking food using the heating container 301 having the above-described configuration will be described. First, as shown in FIG. 37, various ingredients constituting a desired dish are placed on the bottom 302 of the heating container 301. In the illustrated example, an egg is placed on the center of the heating vessel 301, and three pieces of raw broccoli and two pieces of thick bacon are placed on both end regions in the longitudinal direction. Also, a tablespoon of water is added to make the ingredients plump. The dimensions of the heating container 301 shown in FIG. 37 are such that the length in the longitudinal direction of the bottom 302 of the heating container 301 is about 16 cm, the width is about 8 cm, and the height H of the side wall 303 (shown in FIG. 36). It is about 3.5 cm. Further, the height difference h (shown in FIG. 35) of the peak portion 330b and the valley portion 331b of the arc-shaped portion 302b is set to 4 mm.

  And the heating container 301 which accommodated the foodstuff is mounted in a microwave oven, and the heating by a microwave oven is performed for a predetermined time. In the illustrated example, heating was performed in a microwave oven at 600 W for about 2 minutes and 30 seconds. When heating by the microwave oven is performed in this way, microwaves emitted from the microwave oven are irradiated to the foodstuff and the heating container 301. As a result, the food is heated from the inside by microwave irradiation, and the conductive material layer 304 provided on the bottom 302 and the side wall 303 of the heating container 301 is heated to generate heat due to the microwave irradiation. As a result, heat is also applied from below and from the sides by heat conduction from the conductive material layer 304. At this time, the conductive material layer 304 directly heats the surface of the food material in contact with the conductive material layer 304, so that the food material is burnt or burnt as desired.

  Here, among the microwaves irradiated to the heating container 301 from the microwave oven, the microwaves that have reached the side wall portion 303 from the outside are reflected, and the intrusion into the heating container 301 (irradiation of food) is blocked. Yes. In addition, microwaves that reach the side wall portion 303 from the inside are reflected, but the surface of the side wall portion 303 (conductive material layer) is formed to be uneven by a plurality of peak portions 330a and 330b and valley portions 331a and 331b. Therefore, the microwave is reflected on the surface of the side wall portion 303 (conductive material layer) and diffuses in all directions. Therefore, compared with the case where the side wall part 303 is formed smoothly, the amount of microwaves irradiated to the foodstuff decreases.

  As described above, in the heating container 301 of the present embodiment, the conductive material layer 304 is provided on the side wall portion 303 and the side wall portion 303 is formed in a cross-sectional wave shape, thereby directly acting on the food. The food can be cooked in a state where the amount of microwaves, that is, internal heating of the food by microwave irradiation is suppressed. Therefore, the suppression effect can reduce the amount of transpiration of moisture inside the food material, and as a result, the food material after cooking is given a plump and soft texture.

  In addition to the above, for broccoli and thick bacon that are difficult to pass through fire, sufficient heating is performed from both the bottom 302 and the side wall 303 that surrounds the arc, and the bottom 302 and straight line for eggs. Heating that is suppressed to some extent is performed from the side wall portion 303 of the shaped portion 302a. For this reason, moderate heating unevenness can be realized, and all foods can be appropriately heated. In this embodiment, the broccoli and the thickly sliced bacon are sufficiently cooked, but the eggs are in an ideal semi-ripe state.

  Furthermore, FIG. 38 uses the same heating container as described above, and ½ pieces of onions are placed at the center, and ½ pieces of raw potatoes and appropriate amounts of pumpkin are placed at both end regions in the longitudinal direction. In addition, a tablespoon of water is also added to finish the food in the same way as above. This was heated in a microwave oven at 600 W for about 4 minutes. As a result of cooking with the heating container 301 of the present embodiment, potatoes and pumpkins that are difficult to pass through can be cooked plumply, while onions that are easy to pass through can be cooked with moderate hardness. Thus, when the heating container 301 of this embodiment is used, it is possible to realize a state close to heating by a conventional frying pan or oven.

  Moreover, in the heating container 301 of this embodiment, since the side wall part 303 is uneven, since the surface area of the side wall part 303 becomes large, the heat transfer area by the conductive material layer 304 becomes large at the time of heating. In addition, the heating power of the foodstuff is increasing from the side wall portion 303, and the heat can be passed through the foodstuff firmly. On the other hand, since the conductive material layer 304 has a large surface area after cooking, the generated heat is efficiently dissipated and the temperature decreases relatively quickly. In addition, since the heating element constituting the heating container 301 includes thin paper as a constituent element, the heat transmitted from the conductive material layer 304 is effectively radiated without being accumulated. Therefore, in a short time after cooking, the side wall 303 can be picked by hand without worrying about burns and the heating container 301 can be carried.

  The first embodiment of the present invention has been described in detail above, but the specific aspect of the present invention is not limited to the above-described embodiment. For example, in the present embodiment, the heating container 301 has an upper surface opened, and microwaves can be applied to the food from the upper surface. However, as shown in FIG. 39, the heating container 301 can be removed to close the upper surface opening. You may comprise so that the cover 309 may be further provided.

  The lid 309 shown in FIG. 39 has an open bottom surface, and includes a substantially bowl-shaped lid body portion 390 that covers the food, and a hanging wall portion 391 that hangs down from the periphery of the lid body portion 390. Similar to the heating container 301, the lid 390 and the hanging wall 391 are provided with a conductive material layer that generates heat upon irradiation with microwaves on the surface facing the food. That is, the lid 309 is also composed of the heating element 16 shown in FIG. Although the illustrated hanging wall portion 391 of the lid 309 has a planar shape, it may be possible to form peaks and valleys as formed in the heating container 301. By doing so, it is possible to control the amount of foodstuff-irradiated microwaves. In addition, as the heating element constituting the lid 309, a heating element that does not have a concavo-convex shape on the surface like the heating container 301 may be used. The size of the lid 309 is set to be approximately the same as or slightly larger than the size of the heating container 301.

  According to this embodiment, since the upper surface opening of the heating container 301 is covered with the lid 309, the microwave irradiated from above the food is reflected by the conductive material layer 304 of the lid 309, and therefore into the heating container 301. Intrusion of microwaves is suppressed. Therefore, it is possible to substantially block the microwave irradiation to the food material. And since the conductive substance layer provided in the cover body part 390 and the drooping wall part 391 of the cover 309 generates heat by microwave irradiation and becomes high temperature, the food is not only from the lower side and the side by the heat conduction. And it comes to be heated from above. As a result, since the food is heated not by internal heating by microwave irradiation but by external heating by heat conduction from the conductive material layer 304, the amount of water transpiration inside the food can be reduced, and more conventional It is possible to realize a state close to heating by a frying pan or an oven.

  FIG. 40 is a diagram showing the heating container 301 and the auxiliary container 321 according to the embodiment. The auxiliary container 321 has a schematic shape corresponding to the heating container 301, but its size is slightly larger than that of the heating container 301. For this reason, the heating container 301 can be accommodated and held therein. The role of the auxiliary container 321 is to maintain the shape of the heating container 301. This is because, as described above, the heating container 301 itself is basically formed of the heating element 16 based on thin paper, and therefore when the highly fluid food is put in the heating container 301, the side wall portion It is also conceivable that 303 falls down. This is inconvenient for cooking using highly fluid ingredients. For this reason, the heating container 301 is accommodated in the auxiliary container 321 and the deformation of the heating container 301 is prevented by the rigidity of the auxiliary container 321.

  For the above purpose, the auxiliary container 321 can be formed of thick paper, heat-resistant plastic, or the like as long as it is a material that allows microwaves to pass through. The specific shape of the auxiliary container 321 is not particularly limited as long as it corresponds to the shape of the heating container 301 to some extent, and the peaks 330a and 330b and the valleys 331a formed on the side wall 303 of the heating container 301 are not limited. Irregularities corresponding to 331b may be provided on the side surface portion, or the side surface portion may be formed by a simple plane.

  Next, a modification of the heating container 301 according to the present embodiment will be described with reference to FIG. The basic configuration of the heating container 341 shown in FIG. 41 is the same as that of the heating container 301 shown in FIG. However, the heating container 341 shown in FIG. 41 is different in that a crest and a trough are not formed on the side wall 343a of the linear portion 302a. Thus, when the crest and trough are not formed in the side wall part 343a in the linear part 302a, since the surface area of the said side wall part 343a does not become large, the heat_generation | fever in this part is suppressed. Thus, heating of the central portion of the heating container 341 is also suppressed. Thereby, it becomes possible to realize a more appropriate heating unevenness.

  Next, another modification of the heating container according to the present invention will be described with reference to FIG. A heating container 351 shown in FIG. 42 is different from the heating container 301 shown in FIG. 34 or the like in that the bottom 352 has a rectangular shape with rounded corners. Specifically, the length of the long side (longitudinal direction) of the bottom 352 is about 12 cm, and the length of the short side is about 6.5 cm. Moreover, the height of the side wall part 353 is about 4.5 cm. In addition, each corner of the bottom 352 is rounded in plan view, but its radius is about 2 cm.

  Also in the case of the heating container 351 formed in this way, as with the heating container 301 described above, appropriate heating unevenness can be generated. That is, the food in the central region of the heating container 351 is heated from the bottom 352 and the two side walls 353, whereas the food in the longitudinal end regions is heated from the bottom 352 and the three side walls 353. Is done. For this reason, overheating to the foodstuff of a center area | region is prevented, and sufficient heating is made | formed with respect to the foodstuff of a both-ends area | region.

  At this time, the heating container 351 of the present embodiment can suppress the concentration of microwaves because the corners are rounded, and problems such as excessive scoring that occurs in a heating container whose corners are not rounded. Does not occur. Note that the radius of curvature when rounding the corner is not limited to 2 cm, but can be selected in the range of about 1 cm to 3 cm. Further, when rounding corners, the present invention is not limited to arcs, and an arbitrary curve that does not cause corners can be selected. Furthermore, in the heating container 351 of the present embodiment, the bottom 352 is substantially rectangular, but may be a pentagon or other polygons. Note that the heating container 351 according to the embodiment may also be configured not to form peaks and valleys on the side wall at the position corresponding to the linear portion, like the heating container 341 shown in FIG.

  Hereinafter, although there is a portion overlapping with the above-described embodiment, characteristic configurations of the present invention will be listed.

  The heating auxiliary member 1 or the heating container 101, 201, 301, 341, 351 according to the present invention includes heating elements 4, 5, 16 having a conductive material layer capable of induction heating by microwave irradiation, A plurality of concavo-convex portions are formed on the surfaces of the heating elements 4, 5, and 16, and the pressure-bonding area ratio, which is the ratio of the area of the concave portions 14 to the area of the concavo-convex portions, is 20% or more and 80% or less.

  In this way, since the heating elements 4, 5, and 16 include the concavo-convex portion having the above-described pressure-bonding area ratio, by preventing overheating of the heating elements 4, 5, and 16, The surface of F can be heated more uniformly, and the occurrence of problems such as local overheating, burning, and deformation in the heating auxiliary member 1 or the heating containers 101, 201, 301, 341, and 351 can be suppressed. Therefore, it is possible to obtain the heating auxiliary member 1 or the heating container 101, 201, 301, 341, 351 having excellent durability that can be used repeatedly.

  In the heating auxiliary member 1 or the heating containers 101, 201, 301, 341, and 351, the depth H (see FIG. 2) of the concave portions 14 in the concave and convex portions may be 0.01 mm or more and 2.0 mm or less. The depth of the concave portion 14 refers to the depth from the position of the upper surface of the convex portion adjacent to the concave portion 14 to the bottom surface of the concave portion 14.

  Thus, by setting the range of the depth of the recess 14, it is possible to reliably suppress the occurrence of problems such as local overheating in the heating auxiliary member 1 as described above. The reason why the lower limit of the depth of the concave portion 14 is set to 0.01 mm as described above is that, when the depth of the concave portion 14 is smaller than this value, there is a difference in effect from the flat state where the concave and convex portions are not formed. It is because it stops coming out. The reason why the upper limit of the depth of the recess 14 is set to 2.0 mm as described above is that if the depth of the recess 14 is made deeper than this value, the workability of the heating auxiliary member may be deteriorated. In addition, the lower limit value of the depth of the recess 14 is preferably 0.02 mm, more preferably 0.05 mm. Moreover, the upper limit of the depth of the recessed part 14 becomes like this. Preferably it is 1.5 mm, More preferably, it is 1.0 mm.

  In the heating auxiliary member 1 or the heating container 101, 201, 301, 341, 351, the width of the concave portion 14 in the concavo-convex portion is 0.5 mm or more, and the distance between adjacent concave portions 14 in the concavo-convex portion (for example, FIG. 2 or a distance W in FIG. 9 (W = X−Y) or less. Note that the width of the recess 14 refers to the distance (Y) between the side walls of the recess 14 at the upper end of the recess 14 in the configuration shown in FIGS. Further, when the plurality of recesses 14 extend in parallel with an interval in plan view, the width of the recess 14 in the direction perpendicular to the direction in which the recess 14 extends is defined as the width of the recess 14. . In addition, when a plurality of values can be defined as the width of the recess 14 depending on the planar shape of the recess 14, the distance between the side walls that are closest to each other in the recess 14 is the width of the recess 14.

  Thus, by prescribing the width of the recess 14, the bent shape of the heating auxiliary member as described above can be easily maintained, and the effect of suppressing the occurrence of problems such as local overheating can be reliably obtained. be able to. The reason why the lower limit of the width of the recess 14 is set to 0.5 mm as described above is that the above-described effects cannot be clearly obtained if the width of the recess 14 is narrower than this value. The upper limit of the width of the recess 14 is set to the distance W between the recesses 14 when the width of the recess 14 is larger than the distance W between the adjacent recesses 14. This is because the surface area of the object to be heated cannot be sufficiently heated as a result of the reduction of the area of the direct contact portion. The lower limit of the width of the recess 14 is preferably 0.7 mm, more preferably 1 mm, and still more preferably 1.5 mm.

  In the heating auxiliary member 1, the heating elements 4, 5, 16 may include the first heating element 4 and the second heating element 5. The heating auxiliary member 1 may include a first support part 2 on which the first heating element 4 is laminated and a second support part 3 on which the second heating element 5 is laminated. The first support 2 and the second support 3 are configured so that the second heating element 4 and the second heating element 4 can contact the object F to be heated placed on the first heating element 4. The body 5 is connected so as to face the body 5. In this case, for example, the first heating element 4 and the second heating element 5 are arranged such that the object to be heated F is arranged on the first heating element 4 and the second heating element 5 contacts the object to be heated F. Can be arranged. For this reason, a burn can be given to both surfaces of the to-be-heated material F. FIG.

  In the heating auxiliary member 1, the first support 2 and the second support 3 are connected at a plurality of locations so as to maintain the first heating element 4 and the second heating element 5 facing each other. Also good. If it does in this way, the to-be-heated material F will be pinched | interposed between the 1st support part 2 and the 2nd support part 3 rather than the case where the 1st support part 2 and the 2nd support part 3 are connected by one place. It can be securely held in a state.

  The heating containers 101, 201, 301, 341, 351 serving as the heating auxiliary members are the bottom surface portions 102, 202, 302, 352 and the side surface portions 103 or the side wall portions 203 that rise from the periphery of the bottom surface portions 102, 202, 302, 352. , 303, 353 may be provided. The main body portion may be constituted by the heating element 16. In this case, it is possible to realize a heating auxiliary member that can be repeatedly used and that can heat the object to be heated by disposing the object to be heated inside the cup-shaped main body.

  In the heating auxiliary member 1 or the heating container 101, 201, 301, 341, 351, the cross-sectional shape of the convex portion 25 in the concave and convex portion may be rectangular or circular. In this case, the uneven portion of the heating element 16 can be easily formed using roll rolling or pressing.

  In the heating auxiliary member 1, the first support 2 and the second support 3 may be bent so that the first heating element 4 and the second heating element 5 can be arranged to face each other. Good.

  In this case, when the object to be heated F is heated in the microwave using the heating auxiliary member 1, the object to be heated F is placed on the first support portion 2 via the first heating element 4. , The bottom is burnt. And since the 1st support part 2 and the 2nd support part 3 are connected so that bending is possible, the 1st heating element 4 on the 1st support part 2 is connected to the to-be-heated object F. 2 The 2nd heat generating body 5 on the support part 3 can contact. For this reason, a burn can also be given to the upper surface of the article F to be heated. Thus, by using the heating auxiliary member 1, it is possible to simultaneously impart burns to both surfaces of the article to be heated F.

  Moreover, since both surfaces of the to-be-heated material F can be heated simultaneously, the work to turn over does not need to be performed and there is no fear that the to-be-heated material F collapses due to the work. Moreover, since the 1st support part 2 and the 2nd support part 3 are connected, the 2nd heat generating body 5 supported by the 2nd support part 3 slips down from the to-be-heated material F during a heating within a microwave oven. Etc. can be prevented.

  In addition, by using the heating auxiliary member 1 and scorching the fish or the like as the object to be heated F, it is possible to reduce the generation of smoke compared to grilling the fish with a grill or the like. In addition, although the said to-be-heated material F is a concept including fish, meat, the food cooled after cooking, what is called frozen food, cereals, raw vegetables, chicken, etc., it is especially requested | required to be burnt. It is preferable that it is a raw fish of the same size as the fillet fish or fillet fish. In addition, fried chicken can be made by heating the prepared chicken with the heating auxiliary member 1.

  In the heating auxiliary member 1, the first support portion 2 and the second support portion 3 may be connected directly to each other in a bendable manner, or via a bendable connection portion 6. May be connected. In this case, for example, in the configuration in which the first support portion 2 and the second support portion 3 are directly connected to each other, the configuration of the heating auxiliary member 1 is made more than when the independent connection portion 6 is formed. It can be simplified. For this reason, the manufacturing cost of the heating auxiliary member 1 can be reduced. Moreover, when connecting the 1st support part 2 and the 2nd support part 3 via the connection part 6 which can be bent, by adjusting the size and arrangement | positioning of the connection part 6, the 1st support part 2 and The repulsive force of bending between the first support part 2 and the second support part 3 can be reduced as compared with the case where the second support part 3 is directly connected. For this reason, the second heating element 5 supported on the second support part 3 is more likely to come into contact with the object to be heated F placed on the first heating element 4 on the first support part 2. The contact area between the heating auxiliary member 1 and the object to be heated F is increased, and the upper surface of the object to be heated F can be burned more.

  In the heating auxiliary member 1, a portion where the first support portion 2 and the second support portion 3 are connected so as to be bendable is disposed so as to connect the first support portion 2 and the second support portion 3. A bendable connecting portion 6 may be included, and the connecting portion 6 is formed so as to partially connect the first support portion 2 and the second support portion 3, for example, as shown in FIG. 1. May be. In this case, the repulsive force of bending between the first support portion 2 and the second support portion 3 can be reliably reduced as compared with the case where the first support portion 2 and the second support portion 3 are directly connected. For this reason, the second heating element 5 supported on the second support part 3 is more likely to come into contact with the object to be heated placed on the first heating element 4 on the first support part 2. The area (contact area) of the part which contacts the to-be-heated material F in the member 1 can be increased.

  In the heating auxiliary member 1, the connecting portion 6 partially connects the first support portion 2 and the second support portion 3, and may be formed at a plurality of locations as shown in FIG. 13 and the like. In this case, when the second support portion 3 is arranged so as to overlap the first support portion 2 by bending the connection portion 6, the second support portion 3 can be reliably held by the connection portion 6. And the freedom degree of design in the case of setting the arrangement and size of the connecting portion 6 can be increased.

  In the heating auxiliary member 1, the connecting portion 6 has a length corresponding to the distance between the first support portion 2 and the second support portion 3 (for example, the length in the left-right direction of the connecting body 62 in FIG. 13) of 5 mm or more and 50 mm. It may be the following. From a different point of view, the connecting portion 6 has a gap between the first support portion 2 and the second support portion 3 in a state where the first support portion 2 and the second support portion 3 sandwich the object to be heated F. Is preferably 5 mm or more and 50 mm or less.

  In this case, the length of the connecting portion 6 may be adjusted according to the thickness of the object to be heated F, and the second heating element 5 supported on the second support portion 3 is formed on the surface of a fish fillet or the like. It becomes easier to contact.

  In the heating auxiliary member 1, at least one of the first support part 2 and the second support part 3 includes a flap 9 formed so as to extend toward the other support part at the outer peripheral edge part. You may go out.

  In this case, since the said flap 9 is formed, it can prevent that the oil and water of the to-be-heated material F are scattered in a microwave oven during a heating. In addition, this flap 9 may be formed in the 1st support part 2, may be formed in the 2nd support part 3, and also both the 1st support part 2 and the 2nd support part 3 are used. It may be formed. Here, when each support part 2 and 3 is formed with paper, it may deform | transform during heating. For example, the second support portion 3 that is the upper support portion on which the article to be heated F is not placed may be particularly deformed. However, the second support portion 3 can be deformed by forming the flap 9. Can be suppressed. Further, by forming the flap 9 on the first support part 2, that is, the lower support part, the oil and water flowing out from the heated object F during the heating are blocked to prevent contamination in the microwave oven. be able to.

  In the heating auxiliary member 1, the flap 9 may be formed by bending the outer peripheral edge portion of the one support portion (for example, the second support portion 3 in FIG. 22). In this case, the structure and manufacturing process of the heating auxiliary member 1 can be simplified as compared to the case where another member is connected as the flap 9 to the first support portion 2 or the second support portion 3 separately.

  In the heating auxiliary member 1, the first support 2 and the second support 3 are connected at a plurality of locations so as to maintain the first heating element 4 and the second heating element 5 facing each other. Also good. If it does in this way, the to-be-heated material F will be pinched | interposed between the 1st support part 2 and the 2nd support part 3 rather than the case where the 1st support part 2 and the 2nd support part 3 are connected by one place. It can be securely held in a state.

  In the heating auxiliary member 1, the outer peripheral edge portions of the first support portion 2 and the second support portion 3 are connected to each other so that a cylindrical body is formed by the first support portion 2 and the second support portion 3. May be. By adopting such a cylindrical body, the first heating element 4 and the second heating element 5 are reliably brought into contact with the heated object F by arranging the heated object F inside the cylindrical body. Can do.

  In the heating auxiliary member 1, the first support portion 2 and the second support portion 3 leave each other with at least a part so that a bag-like body is formed by the first support portion 2 and the second support portion 3. The outer peripheral edge portions may be connected to each other (that is, the first peripheral portion 2 and the second supporting portion 3 may be intermittently connected to each other). In this case, since free ends are intermittently formed at the outer peripheral edge portions of the first support portion 2 and the second support portion 3, the outer peripheral edge portions of the first support portion 2 and the second support portion 3 are The degree of freedom of deformation of the first support portion 2 and the second support portion 3 can be increased as compared to the case where the connection portions are continuously connected (that is, the first support portion 2 and the second support portion 3 are arranged so as to follow the shape of the object to be heated F). The second support part 3 can be easily deformed).

  In the heating auxiliary member 1, at least one of the first support portion 2 and the second support portion 3 may be configured to follow the shape of the article to be heated F. For example, in the heating auxiliary member 1, at least one fold line (for example, the fold line 21 or the fold line 31 in FIG. 14) is formed on at least one of the first support part 2 and the second support part 3 so as to follow the shape of the article to be heated F. May be formed.

  In this case, for example, when the object to be heated F has a curved surface, such as the skin side where three fish are put down, the fold line 21 or the fold line 31 is along the curved surface, so that the surface of the object to be heated F is more In addition, the heating element (the first heating element 4 or the second heating element 5) can be contacted over a wide range.

  In the heating auxiliary member 1, as shown in FIG. 14, the fold lines 21 and 31 are formed so as to extend in a direction along the extending direction of the connecting portion between the first support portion 2 and the second support portion 3. Also good. Further, in the heating auxiliary member 1, the fold lines 21 and 31 may be constituted by folding lines 212 and 312 and cutout portions 211 and 311. By forming such folds 21 and 31, the first support 2 or the second support 3 can be easily bent along the folds 21 and 31. For this reason, the 1st support part 2 or the 2nd support part 3 can be easily changed along the shape of the to-be-heated material F. FIG.

  In the heating auxiliary member 1, a region where neither the first heating element 4 nor the second heating element 5 is formed may be provided on at least one outer peripheral edge of the first support part 2 and the second support part 3. In this case, since the outer peripheral edge portion of each support portion is easily in contact with the other support portion, the outer peripheral edge portion is exposed, i.e., by providing a region where no heating element is formed on the outer peripheral edge portion, It is possible to prevent overheating caused by the direct contact between the first heating element 4 formed on the first support part 2 and the second heating element 5 formed on the second support part 3.

  In the heating auxiliary member 1, at least one of the first support part 2 and the second support part 3 may be capable of absorbing oil and / or moisture. Further, from a different point of view, at least one of the first support part 2 and the second support part 3 may be formed of a material that absorbs oil or moisture from the article to be heated F by heating. preferable. In this case, it is possible to prevent the inside of the microwave oven from being soiled by the oil or moisture from the object to be heated F by being heated. The material that absorbs oil and moisture is not particularly limited, and examples thereof include paper, nonwoven fabric, woven fabric, sponge, and urethane.

  In the heating auxiliary member 1, a protruding portion 8 may be formed on at least one of the first support portion 2 and the second support portion 3 so as to prevent contact between the first heating element 4 and the second heating element 5. . In this case, the protrusions 8 can be formed on at least one of the first support part 2 and the second support part 3 to prevent contact between the first heating element 4 and the second heating element 5. As a result, overheating can be prevented.

  In the heating auxiliary member 1, a wall portion 7 may be formed on the first support portion 2 on at least a part of the periphery of the first heating element 4. In the heating auxiliary member 1, the first support portion 2 may be formed with a wall portion 7 surrounding the first heating element 4.

  In this case, the wall portion 7 can prevent the oil and moisture from the heated object F from spreading into the microwave oven when heated. Further, the wall portion 7 makes it difficult for the first support portion 2 and the second support portion 3 to come into contact with each other, thereby preventing overheating in advance. Furthermore, by forming the wall portion 7 over the entire circumference of the outer peripheral edge of the first support portion 2 (so as to surround the entire circumference of the first heating element 4), oil and moisture are more reliably contained in the microwave oven. Can be prevented from spreading. Moreover, the effect is further reinforced by forming this wall part 7 with the material which absorbs the oil component from the to-be-heated material F. FIG.

  In the heating auxiliary member 1, the end portions of the first support portion 2 and the end portions of the second support portion 3 are engaged with each other (for example, formed in the second support portion 3 in FIGS. 21 and 22). The notch part 32 and the locking part 22) formed by making the notch 23 in the first support part 2 may be formed.

  In this case, the state in which the second heating element 5 formed on the second support portion 3 is in contact with the article to be heated F can be reliably maintained. For this reason, a contact area with the to-be-heated material F can be increased, and a burnt surface can be given to the whole surface, and further, direct contact between the first heating element 4 and the second heating element 5 can be effectively performed. It can also be prevented.

  Further, when the auxiliary heating member 1 is accommodated in an outer container such as a box or a bag, the first support portion 2 and the second support portion 3 are bent at the connecting portion 6, and the first support portion 2 and the second support portion 3 are folded. 2 It is preferable to fold the support portion 3 from the fold lines 21 and 31 and place it in the exterior container. According to this, since the 1st support part 2, the 2nd support part 3, and the connection part 6 become crooked in the state bent, the heating auxiliary member 1 is followed along the shape of the to-be-heated object F at the time of cooking by a microwave oven. It can be bent more easily. Therefore, the heating auxiliary member 1 can be brought into contact with the article to be heated F in a wider area.

(Experimental example 1)
The following experiment was conducted in order to confirm the state of occurrence of burns during heating cooking in the heating auxiliary member according to the present invention.

(sample)
As a sample for the experiment, a heating element having a square shape of a planar shape and a size of 150 mm × 90 mm in length × width was prepared. As a sample of the example, a heating element having an uneven surface on the front and back surfaces was used. Two types of samples of the examples were prepared. In addition, the planar shape of the concavo-convex structure in the heating element which is the sample of Example 1 is the same as the concavo-convex structure of the heating element shown in FIG. Further, the uneven structure of the heating element of the sample of Example 2 is the same as the uneven structure of the heating element shown in FIGS.

  On the other hand, as a sample of a comparative example, the heating element is not particularly subjected to uneven processing (flat shape), and is provided with uneven processing, but the crimp area ratio is outside the scope of the present invention ( Samples were prepared using a total of four types of comparative heating elements (three types).

(Experiment contents)
About the prepared sample of Example 1, Example 2, and Comparative Example 1- Comparative Example 4, the four corners were fixed to the earthenware dish with the adhesive tape. And the sample fixed to these earthenware dishes was heated on condition that the wattage was 600 W and the heating time was 1 minute in the microwave oven (model number: ER-G3) made by Toshiba Corporation. Then, the state of occurrence of burns in the heated sample was visually confirmed.

(result)
The results of the experiment are shown in Table 1 below.

  In Table 1, the pressure-bonding area ratio in the heating element in each sample, the design value of the depth of the recess (emboss depth) (the design value of the height of the projection formed on the roll surface used for processing) It shows the embossing depth), embossing conditions, and the presence or absence of burns. Note that the embossing condition indicates whether embossing (processing for forming the concavo-convex portion) has been performed only on the front surface or both of the front and back surfaces of the heating element.

  As can be seen from Table 1, all the samples of the comparative examples were burnt. On the other hand, no burn occurred in the examples of the present invention.

  The embodiment disclosed this time should be considered as illustrative in all points and not restrictive. The scope of the present invention is defined by the terms of the claims, rather than the description above, and is intended to include any modifications within the scope and meaning equivalent to the terms of the claims.
