As a result, for example, even if the storage case C is dropped, the contained body 10 can be protected.

本実施例の収容ケースＣ（図１乃至図７参照）にあっては、対向する左側部１２と右側部１３の面積は同じであり、また、対向する正面部１４と背面部１５の面積は同じであり、正面部１４の面積は左側部１２の面積より大となっている。そして、第３の突起群２３、第４の突起群２４が弾性部材で形成され、第３の突起群２３及び第４の突起群２４の突起が、図５に示すように、底部１１に向かって傾斜している。第３の突起群２３、第４の突起群２４は、例えば、シリコン樹脂で形成されている。
その結果、蓋体１７を開けたとき、第３の突起群２３及び第４の突起群２４の突起が、底部１１に向かって傾斜しているため、収容ケース本体１内に収容した被収容体１０が開口部１６から抜け出るのを防止することができる。
なお、第１の突起群２１、第２の突起群２２、第３の突起群２３、第４の突起群２４、第５の突起群２５、第６の突起群２６は、底部１１、左側部１２、右側部１３、正面部１４、背面部１５、底部１１、蓋体１７と共に、例えば、シリコン樹脂で一体的に形成されて収容ケースＣを構成している。 In the storage case C of this embodiment (see FIGS. 1 to 7), the areas of the left side portion 12 and the right side portion 13 that face each other are the same, and the areas of the front portion 14 and the back portion 15 that face each other are the same. It is the same, and the area of the front part 14 is larger than the area of the left part 12. Then, the third protrusion group 23 and the fourth protrusion group 24 are formed of an elastic member, and the protrusions of the third protrusion group 23 and the fourth protrusion group 24 face the bottom 11 as shown in FIG. 5. Is inclined. The third protrusion group 23 and the fourth protrusion group 24 are formed of, for example, a silicone resin.
As a result, when the lid body 17 is opened, the projections of the third projection group 23 and the fourth projection group 24 are inclined toward the bottom portion 11. 10 can be prevented from coming out of the opening 16.
The first projection group 21, the second projection group 22, the third projection group 23, the fourth projection group 24, the fifth projection group 25, and the sixth projection group 26 are the bottom portion 11 and the left side portion. 12, the right side portion 13, the front portion 14, the back portion 15, the bottom portion 11, and the lid body 17 are integrally formed of, for example, silicon resin to constitute the housing case C.

また、上述の実施例の収容ケースＣ（図１乃至図７参照）にあっては、第１の突起群２１〜第６の突起群２６を設けたが、本願発明においては、これに限らず、第１の突起群２１〜第６の突起群２６の内、第６の突起群２６のみを省略することもできる。
また、上述の実施例の収容ケースＣ（図１乃至図７参照）にあっては、対向する左側部１２と右側部１３の面積は同じであり、また、対向する正面部１４と背面部１５の面積は同じであり、正面部１４の面積は左側部１２の面積より大となっていたが、本願発明においては、これに限らず、左側部１２、右側部１３、正面部１４、背面部１５の面積が略同じ場合、第１の突起群２１、第２の突起群２２、第３の突起群２３、第４の突起群２４の突起を底部１１に向かって傾斜するように構成しても良い。 Further, in the housing case C (see FIGS. 1 to 7) of the above-described embodiment, the first protrusion group 21 to the sixth protrusion group 26 are provided. However, the present invention is not limited to this. Of the first to sixth projection groups 21 to 26, only the sixth projection group 26 can be omitted.
Further, in the case C (see FIGS. 1 to 7) of the above-described embodiment, the areas of the left side portion 12 and the right side portion 13 facing each other are the same, and the front portion 14 and the rear portion 15 facing each other. The area of the front portion 14 is larger than the area of the left side portion 12, but in the present invention, the present invention is not limited to this, and the left side portion 12, the right side portion 13, the front portion 14, and the back portion. When the areas of 15 are substantially the same, the protrusions of the first protrusion group 21, the second protrusion group 22, the third protrusion group 23, and the fourth protrusion group 24 are configured to be inclined toward the bottom portion 11. Also good.

また、上述の実施例の収容ケースＣ（図１乃至図７参照）にあっては、厚みを有した平面状の左側部１２、右側部１３を備えていたが、本願発明においては、これに限らず、平面状の左側部１２、右側部１３を有しない、つまり、面でない線状の左側部１２、面でない線状の右側部１３を有する収容ケースＣ（図１乃至図７記載の収容ケースＣに比較し、厚みがない分、扁平状の収容ケース）にも適用することができる。
かかる場合の収容ケースＣ（扁平状の収容ケース）は、被収容体１０を収容する袋状の収容ケース本体１と、被収容体１０を出し入れする開口部１６を開閉する蓋体１７と、収容ケース本体１の対向する一方の内壁（図５で言えば、正面部１４の内壁）に設けられた複数の突起からなる第１の突起群（図５で言えば、第３の突起群２３が相当する）と、収容ケース本体１の対向する他方の内壁（図５で言えば、背面部１５の内壁）に設けられた複数の突起からなる第２の突起群（図５で言えば、第４の突起群２４が相当する）とを備え、被収容体１０が前記一方の内壁及び前記他方の内壁から離間すると共に、前記第１の突起群（図５で言えば、第３の突起群２３が相当する）、前記第２の突起群（図５で言えば、第４の突起群２４が相当する）の内の何れか一つに支持され、収容ケース本体１内に収容されていることとなる。
その結果、上述した収容ケースＣによれば、被収容体１０が一方の内壁（図５で言えば、正面部１４の内壁）及び他方の内壁（図５で言えば、背面部１５の内壁）から離間すると共に、第１の突起群（図５で言えば、第３の突起群２３が相当する）、第２の突起群（図５で言えば、第４の突起群２４が相当する）の内の何れか一つに支持され、収容ケース本体１内に収容されているため、例えば、収容ケースＣを落としても、被収容体１０を保護することができる。 In addition, the storage case C (see FIGS. 1 to 7) of the above-described embodiment includes the planar left side portion 12 and right side portion 13 having a thickness. The housing case C is not limited to the planar left side 12 and the right side 13, that is, has a linear left side 12 that is not a plane, and a linear right side 13 that is not a plane (the housing described in FIGS. 1 to 7). As compared with the case C, it can be applied to a flat-shaped storage case) because there is no thickness.
The storage case C (flat storage case) in this case includes a bag-shaped storage case main body 1 for storing the object to be stored 10, a lid 17 for opening and closing the opening 16 for taking in and out the object to be stored 10, and storage A first protrusion group (in FIG. 5, a third protrusion group 23) composed of a plurality of protrusions provided on one opposing inner wall of the case body 1 (in FIG. 5, the inner wall of the front portion 14). And a second protrusion group (in FIG. 5, the first protrusion group) is formed of a plurality of protrusions provided on the other opposing inner wall (in FIG. 5, the inner wall of the back surface portion 15). 4 projection group 24), and the object 10 is separated from the one inner wall and the other inner wall, and the first projection group (in FIG. 5, the third projection group). And the second protrusion group (in FIG. 5, the fourth protrusion group 24 corresponds. ) Is supported on any one of the, and that it is housed in the housing case main body 1.
As a result, according to the storage case C described above, the object to be stored 10 has one inner wall (in FIG. 5, the inner wall of the front portion 14) and the other inner wall (in FIG. 5, the inner wall of the back surface portion 15). The first protrusion group (corresponding to the third protrusion group 23 in FIG. 5) and the second protrusion group (corresponding to the fourth protrusion group 24 in FIG. 5). For example, even if the storage case C is dropped, the object to be stored 10 can be protected because it is supported by any one of the storage case and stored in the storage case body 1.
