請求項１の発明に係る電子レンジ加熱食品用容器によると、容器本体部と、前記容器本体部の開口部と嵌合する蓋体部とを備え、前記容器本体部内に食品を収容する電子レンジ加熱のための食品用容器であって、前記蓋体部の蓋面部に、電子レンジ加熱に際し前記容器本体部内に収容された食品から発生する水蒸気を外部に排気する複数の排気細孔からなる排気孔群が形成されていて、前記排気細孔の直径は０．５９ｍｍ以下であり、前記排気細孔の個数は８ないし１０００個であるため、従前のＵ字状またはＶ字状の切れ込みによる舌片状の開口部を用いた水蒸気の排気に代わり、良好な水蒸気排気及び封止性能改善を実現し、併せて蓋体部の形状上の制約も少なく、資材コストの軽減も可能となる。 According to the microwave-heated food container according to the invention of claim 1, the microwave oven includes a container main body part and a lid part that fits into the opening of the container main body part, and stores the food in the container main body part. A food container for heating, comprising: a plurality of exhaust pores for exhausting water vapor generated from the food stored in the container main body to the outside when the microwave oven is heated on the lid surface of the lid body Since a hole group is formed, the diameter of the exhaust pore is 0.59 mm or less, and the number of the exhaust pores is 8 to 1000, a tongue formed by a conventional U-shaped or V-shaped cut. Instead of steam exhaust using a piece-like opening, good steam exhaust and improved sealing performance are realized, and there are also few restrictions on the shape of the lid, and material costs can be reduced.

ここで、排気孔群２０を構成する排気細孔２１を規定する指標についてさらに詳述する。一つ目の指標として、個々の排気細孔２１の直径は少なくとも０．５９ｍｍ以下である。さらには、排気細孔２１の直径は０．１５ないし０．５ｍｍの範囲であることが好ましく、特には、０．１９ないし０．３５ｍｍの範囲であることが好ましい。 Here, the index that defines the exhaust hole 21 constituting the exhaust hole group 20 will be further described in detail. As a first index, the diameter of each exhaust pore 21 is at least 0.59 mm. Furthermore, the diameter of the exhaust pores 21 is preferably in the range of 0.15 to 0.5 mm, and particularly preferably in the range of 0.19 to 0.35 mm.

排気細孔２１の直径が大きくなりすぎる場合、排気細孔２１からの異物混入のおそれも高まる。そこで、極力異物の混入を規制する必要性と内部発生水蒸気の排気との両立から直径０．５９ｍｍ以下が導き出される。直径の下限の０．１５ｍｍはおおよそ現状の加工技術を考慮した値である。排気細孔２１の直径が０．１５ｍｍを下回る場合、孔直径は小さすぎであり排気細孔２１からの水蒸気の排気効率は低下すると考えられる。結果、容器本体部１００に嵌合した蓋体部１０が内圧により外れやすくなる。また、レーザー光線の照射装置の精度上の下限とも考えられる。 When the diameter of the exhaust pore 21 becomes too large, the possibility of contamination from the exhaust pore 21 increases. Accordingly, a diameter of 0.59 mm or less is derived from the necessity of regulating the mixing of foreign substances as much as possible and the exhaust of internally generated water vapor. The lower limit of 0.15 mm in diameter is a value that takes into account the current processing technology. When the diameter of the exhaust pore 21 is less than 0.15 mm, the pore diameter is too small, and the exhaust efficiency of water vapor from the exhaust pore 21 is considered to decrease. As a result, the lid body portion 10 fitted to the container main body portion 100 is easily removed by the internal pressure. It can also be considered as a lower limit on the accuracy of the laser beam irradiation apparatus.

［排気細孔の物性範囲の考察］
計６種類の食品例毎の電子レンジ加熱試験（表１ないし６参照）を踏まえた結果、好例な排気細孔に関する範囲は次のとおり導き出すことができる。まず、表１より、排気細孔はその個数によるものの、０．５９または０．５０ｍｍの直径も許容される。さらには、水蒸気排気の性能と異物混入抑制の両立から、０．３５ｍｍをより好ましい直径の上限とした。排気細孔の直径の下限は照射装置の性能に依存する。しかしながら、極端に直径を狭くすると水蒸気の排気効率は低下するため、一連の実験結果から少なくとも０．１５ｍｍは必要であり、好ましくは実験時の下限である０．１９ｍｍと判断した。
（以上） [Consideration of physical properties of exhaust pores]
As a result of taking into account the microwave heating test (see Tables 1 to 6) for each of the six types of food examples, a range related to good exhaust pores can be derived as follows. First, from Table 1, although the number of exhaust pores depends on the number thereof, a diameter of 0.59 or 0.50 mm is allowed . It is Raniwa, from both performance and contamination suppression of steam exhaust, and a more preferable upper limit of the diameter 0.35 mm. The lower limit of the diameter of the exhaust pore depends on the performance of the irradiation device. However, since the exhaust efficiency of water vapor decreases when the diameter is extremely narrowed, at least 0.15 mm is necessary from a series of experimental results, and it was determined that 0.19 mm, which is the lower limit during the experiment, is preferable.
(that's all)
