PROBLEM TO BE SOLVED: To develop a new container having observation appropriateness, and allowing housing objects such as relatively small insects and aquatic organisms, in a state facilitating observation.SOLUTION: A container having observation appropriateness is such that: a housing part 5 is formed as a space surrounded with a wall element body 2, and a surrounding element body 3 both of the wall element body 2 and the surrounding element body 3 are configured of a transparent material a solid part 23 in the wall element body 2 can exhibit a prism effect and the housing part 5 can be put into a luminous state by the prism effect so as to facilitate observing a sample. When the sample is a violently moving alive organism such as an insect, standstill observation/photographing become possible in a state of suppressing the movement of the sample by selecting a narrow housing part.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2017,JPO&INPIT【課題】比較的小さな昆虫、水生生物等を対象として、それらを観察し易い状態で収納できる、新規な観察適正を具えた容器の開発を技術課題とした。【解決手段】収納部5を壁要素体2と、囲み要素体3とで囲んだ空間として形成して成り、前記壁要素体2、囲み要素体3は共に透明素材で構成され、且つ壁要素体2における充実部23はプリズム効果を発現するものであることを特徴として成り、収納部5をプリズム効果で光輝状態としサンプルを観察し易くすることができる。またサンプルが昆虫等の動きが激しい生きた生物であっても、狭い収納部を選択すれば、サンプルの動きを抑制した状態で静止観察・写真撮影をすることができる。【選択図】図1
