[0014] The cooking sheet 10 comprises a sheet body 100 having a strip-like outer shape as its main body portion. The cooking sheet 10 is manufactured as a cylindrical roll 310 in which the sheet body 100 is wound around a roll core 300, and is distributed in a state in which it is stored in a holder (not shown). The cooking sheet 10 is used by unwinding the roll 310 and pulling out the sheet body 100 from the holder by the user, and then cutting the sheet body 100 in a direction approximately perpendicular to the pulling direction to process it into a rectangular shape of any desired dimensions.
[0015] The main surface 200 of the sheet body 100 is divided into a front surface 200a corresponding to the inner peripheral surface of the wound body 310 and a back surface 200b corresponding to the outer peripheral surface of the wound body 310.
[0016] The main surface 200 is embossed, whereby a plurality of projections and depressions are formed on the main surface 200 by deformation of a part of the main surface 200 in a direction substantially perpendicular to the main surface 200.
[0017] Specifically, a plurality of first uneven portions 210 consisting of a combination of first convex portions 210a and first concave portions 210b are formed on the front surface 200a, and a plurality of second uneven portions 220 consisting of a combination of second convex portions 220a and second concave portions 220b are formed on the back surface 200b.
[0018] The first protrusion 210a is formed as a protrusion from a part of the surface 200a. The first recess 210b is formed as a depression in another part of the surface 200a different from the part where the first protrusion 210a is formed.
[0019] As shown particularly in FIG. 3, each of the first convex portion 210a and the first concave portion 210b has a substantially circular outline when the base portion is viewed from above.
[0020] The multiple first uneven portions 210 are arranged on the surface 200a along both the longitudinal and lateral directions of the sheet body 100, and are arranged at equal intervals so that the first protrusions 210a or the first recesses 210b are not adjacent to each other or so that the first protrusions 210a and the first recesses 210b are not adjacent to each other. That is, in the sheet body 100, the first protrusions 210a and the first recesses 210b are arranged alternately at equal intervals and are distributed in a plane.
[0021] The second convex portion 220a is formed as a protrusion from a part of the rear surface 200b. The second concave portion 220b is formed as a depression in another part of the rear surface 200b different from the part where the second convex portion 220a is formed.
[0022] As shown particularly in FIG. 4, each of the second convex portion 220a and the second concave portion 220b has a substantially circular outline when the base portion is viewed from above.
[0023] The multiple second uneven portions 220 are arranged on the back surface 200b along both the longitudinal and lateral directions of the sheet body 100, and are arranged at equal intervals so that the second protrusions 220a or the second recesses 220b are not adjacent to each other or so that the second protrusions 220a and the second recesses 220b are not adjacent to each other. That is, in the sheet body 100, the second protrusions 220a and the second recesses 220b are arranged alternately at equal intervals and are distributed in a plane.
[0024] The protrusion of the part of the front surface 200a that forms the first convex part 210a is formed as a depression of the part of the back surface 200b, which corresponds to the second concave part 220b on the back surface 200b.
[0025] The other recesses in the front surface 200a that form the first recesses 210b are formed as protrusions on the back surface 200b, which correspond to the second protrusions 220a on the back surface 200b. That is, the first uneven portion 210 on the front surface 200a is formed as an inverted shape of the second uneven portion 220 on the back surface 200b.
[0026] As shown in FIG. 5, the outer diameter da of the first protrusion 210a is preferably in the range of 2.0 mm to 3.0 mm, more preferably 2.8 mm. The inner diameter db of the first recess 210b is preferably in the range of 1.3 mm to 2.3 mm, more preferably 2.1 mm. If the outer diameter da is less than 2.0 mm and the inner diameter db is less than 1.3 mm, the surface shape of the main surface 200 of the sheet body 100 will essentially be formed only by the front surface 200a and the back surface 200b, which is undesirable. If the outer diameter da is greater than 2.8 mm and the inner diameter db is greater than 2.3 mm, the surface shape of the main surface 200 of the sheet body 100 will essentially be formed by the first protrusion 210a and the second protrusion 220a, which is undesirable. The outer diameter of the second convex portion 220a is the same as the outer diameter da, and the inner diameter of the second concave portion 220b is the same as the inner diameter db.
[0027] Furthermore, the protrusion length h of the first protrusions 210a from the front surface 200a is preferably in the range of 0.4 mm to 0.6 mm. If the protrusion length h is less than 0.4 μm, the surface shape of the main surface 200 of the sheet body 100 will be essentially formed only by the front surface 200a and the back surface 200b, which is undesirable. If the protrusion length h is greater than 0.6 mm, the degree of shape change between the front surface 200a and the first protrusions 210a, and between the back surface 200b and the second protrusions 220a will be too great, resulting in an increase in the outer diameter of the wound body 310 and poor storage capacity, which is undesirable. Note that the protrusion length of the second protrusions 220a from the back surface 200b is the same as the protrusion length h.
[0028] Furthermore, the distance i between adjacent first protrusions 210a is preferably in the range of 5 mm to 8 mm, and more preferably 7 mm. If the distance i is less than 5 mm, the surface shape of the main surface 200 of the sheet body 100 will be substantially formed by the first protrusions 210a and the second protrusions 220a, which is undesirable. If the distance i is greater than 8 mm, the surface shape of the main surface 200 of the sheet body 100 will be substantially formed only by the front surface 200a and the back surface 200b, which is undesirable. The distance between the second protrusions 220a is the same as the distance i.
[0029] The sheet body 100 has a base material 110 made of oil-resistant paper, and a covering portion 120 that covers each of a front surface 200a and a back surface 200b of a main surface 200 of the sheet body 100.
[0030] The base material 110 is made of an oil-resistant paper material. Preferred examples of the paper material include glassine paper and parchment paper. The base material 110 is preferably a single layer, but may be made of a laminate of multiple different types of sheets.
[0031] The covering portion 120 is made of a heat-resistant resin material, such as a silicone resin, but a fluororesin may also be used.
[0032] As shown in Fig. 5, the thickness t of the entire sheet body 100 is preferably in the range of 0.2 mm to 0.5 mm, and more preferably 0.35 mm. If the thickness t is less than 0.2 mm, the sheet body 100 is likely to tear or be cut by a knife during use, which is undesirable. If the thickness t is greater than 0.5 mm, the flexibility of the sheet body 100 decreases, making it difficult to reuse, which is undesirable.
[0033] The cooking sheet 10 according to the embodiment of the present invention includes a sheet body 100 having an oil-resistant, sheet-like substrate 110 and a covering 120 made of a heat-resistant resin-based material that covers the contours of the front and back surfaces 200a and 200b of the substrate 110. The substrate 110 has a first protrusion 210a formed as a protrusion on the front surface 200a, a first recess 210b formed as a recess on another portion of the front surface 200a, a second protrusion 220a formed as a protrusion on the back surface 200b, and a second recess 220b formed as a recess on another portion of the back surface 200b. In a plan view of the substrate 110, the first protrusion 210a is formed in a position overlapping the second protrusion 220a, and in a back view of the substrate 110, the second recess 220b is formed in a position overlapping the first protrusion 210a.
[0034] The cooking sheet 10 according to the embodiment of the present invention has these features and can be used both as a cutting board and as a cooking sheet for a frying pan. That is, the cooking sheet 10 can be used as a cutting board, and ingredients that have been cut with a knife or the like can be moved along with the cooking sheet 10 and placed on a frying pan for cooking.
[0035] Therefore, a single cooking sheet can be used throughout the cooking process, eliminating the hassle of use and reducing the amount of waste that is discarded when cleaning up. As a result, it has versatility that can be used throughout each cooking process and reduces the environmental impact.
[0036] Furthermore, the cooking sheet 10 according to the embodiment of the present invention exhibits the following unique effects when used as a cutting board sheet and when used as a cooking sheet for a frying pan.
[0037] That is, when the cooking sheet 10 is used as a cutting board sheet and placed on the surface of a predetermined table or board such as a cutting board, as shown in Fig. 6, which is an enlarged side view of the main part, the sheet body 100 and the surface S are in contact only via the second recesses 220b, and a gap G is formed in the remaining part. Also, the cooking sheet 10 and the food to be cooked (not shown) are in contact mainly via the first protrusions 210a, and the first protrusions 210a constitute the substantial contact surface of the cooking sheet 10.
[0038] As a result, on the front surface 200a side, the first protrusions 210a act as a buffer, and the pressure of the knife cutting food is reduced after passing through the first protrusions 210a and then transmitted to the front surface 200a. Similarly, on the back surface 200b side, the second protrusions 220a act as a buffer, preventing the pressure of the knife after cutting food from being applied directly to the front surface 200a of the cooking sheet 10. As a result, the risk of the sheet body 100 being scratched or cut by the knife during cooking is reduced, and the durability of the sheet body 100 is improved.
[0039] On the other hand, when the cooking sheet 10 is used as a cooking sheet for a frying pan and placed on the surface of the frying pan, just as when it is used as a cutting board sheet, the sheet body 100 and the surface S are in contact only via the second recesses 220b, with gaps G formed in the remaining areas, as shown in Fig. 6. Also, the cooking sheet 10 and the food to be cooked (not shown) are in contact mainly via the first protrusions 210a, and the first protrusions 210a form the substantial contact surface of the cooking sheet 10.
[0040] As a result, on the front surface 200a side, the juices and oils produced by food during heating flow to the front surface 200a side, which is located closer to the front surface S than the first protrusions 210a, which are the actual contact surfaces, and contact with the food is reduced. Also, on the back surface 200b side, mainly the second protrusions 220a come into direct contact with the front surface S of the frying pan, preventing the back surface 200b from coming into direct contact with the front surface S of the frying pan. As a result, the risk of the sheet body 100 itself burning during heating or of the juices and oils produced by the heated food burning and sticking to the food is reduced, the durability of the sheet body 100 is improved, and food can be heated without compromising its flavor or appearance.
[0041] In this way, the cooking sheet 10 according to the embodiment of the present invention has the unique effect of improving durability when used as a cutting board sheet, and improving durability when used as a cooking sheet for a frying pan, while also being able to heat food without damaging its flavor or appearance.
[0042] Furthermore, in the cooking sheet according to the embodiment of the present invention, the first convex portions 210a and the first concave portions 210b are arranged alternately at equal intervals and are distributed in a plane, and the second convex portions 220a and the second concave portions 220b are also arranged alternately at equal intervals and are distributed in a plane.
[0043] This results in the formation of a pattern of alternating concave and convex shapes on the front surface 200a and the back surface 200b, which not only improves the durability mentioned above and enables food to be heated without impairing its flavor or appearance, but also results in a cooking sheet with excellent appearance.
[0044] Furthermore, in the cooking sheet according to the embodiment of the present invention, when the base material 110 is viewed from above, the first convex portion 210a and the first concave portion 210b have an approximately circular outline, and when the base material 110 is viewed from the bottom, the second convex portion 220a and the second concave portion 220b have an approximately circular outline.
[0045] This makes it possible to uniformly distribute heat and pressure to the unevenness, improving the durability mentioned above and further enhancing the effect of being able to heat food without damaging its flavor or appearance.
[0046] Furthermore, the cooking sheet according to the embodiment of the present invention is made of an oil-resistant paper material. More specifically, it is made of a material whose main component is pulp. This makes it possible to obtain a cooking sheet that is low cost and has a low environmental impact.
[0047] Furthermore, the cooking sheet according to the embodiment of the present invention is made of a material whose main component is a heat-resistant resin, more specifically, a silicone resin, which makes it possible to obtain a cooking sheet that is low-cost, has excellent heat resistance, and is hygienically safe.
[0048] The basis weight of the substrate 110 before the covering 120 is provided and embossed is 0.7 g / m 2 More than 4.0g / m 2 It is preferable to set the thickness within the following ranges: By setting the thickness within the ranges, the sheet has excellent flexibility and can be reused, and when used as a cutting board sheet, the risk of tearing or being cut by a knife is reduced, and when used as a cooking sheet for a frying pan, the risk of burning can be reduced.
[0049] (Variation) The first convex portions and first concave portions, and the second convex portions and second concave portions of the present invention may be arranged at irregular intervals in whole or in part, or may be arranged continuously in whole or in part.
[0050] The first protrusions and first recesses of the present invention may have a substantially rectangular, polygonal, oval, elliptical, or any other shape when viewed from above the base member. Correspondingly, the second protrusions and second recesses may have a substantially rectangular, polygonal, oval, elliptical, or any other shape when viewed from below the base member.
[0051] The substrate of the present invention is not limited by other compositions as long as it has oil resistance and can be processed into a sheet. For example, it may be made of a resin material instead of a material containing pulp as a main component.
[0052] The heat-resistant resin of the present invention is not limited by its composition as long as it is a heat-resistant resin that is safe for food ingredients and the human body. For example, it may be a fluororesin.
[0053] The substrate of the present invention is preferably a material containing pulp as a main component, and the pulp may be natural pulp or synthetic pulp.
[0054] As described above, the embodiment of the present invention has been disclosed in the above description, but the present invention is not limited thereto.
[0055] In other words, various modifications can be made to the above-described embodiments and variants in terms of mechanism, shape, material, quantity, position, arrangement, etc., without departing from the scope of the technical idea and purpose of the present invention, and these modifications are included in the present invention.
