The invention relates to a cultivating device for a plant tissue, comprising a box body and a cover body. The box body is configured with an upper opening, an inner peripheral surface forming the upper opening, and a combination part circumferentially disposed on the upper opening, in which the combination part is firstly outwardly extended from the inner peripheral surface to form a first rough surface and then downwardly extended to form a second rough surface. The cover body is configured with a lower opening and a connection part circumferentially disposed on the lower opening, in which the connection part has a third rough surface that is corresponded to the first rough surface of the box body and protruded with a first protrusion and an external flange that is corresponded to the second rough surface of the box body and inwardly convex-extended with at least one engaging connection block connectively engaged to the combination part of the box body. Accordingly, the box body and the cover body are connectively engaged to each other and not liable to be separated therebetween, and a container formed thereby is still provided with suitable gas permeability when the cover body suffered by an external pressure is tightly combined with the box body.一種植物組織培育裝置,其一蓋體係以其下開口相對一盒體之上開口地蓋設於該盒體,該盒體之上開口係由一內周面所形成並環設一結合部,該結合部係自該內周面先向外延伸一第一粗糙面,再向下延伸一第二粗糙面,該蓋體之下開口環設一連結部,該連結部具有分別與該第一、第二粗糙面相對之一第三粗糙面及一外凸垣,該第三粗糙面並凸出一第一凸塊,且該外凸垣向內凸伸至少一與該結合部卡接之卡接塊;藉此,該盒體及蓋體因相互卡接而不易分離,且當該蓋體因受外加壓力而與該盒體更加緊密結合時,該容器仍具有相當之透氣性。10...植物組織培育裝置20...盒體21...上開口22...底部23...內周面24...結合部241...第一粗糙面242...第二粗糙面25...補強肋26...支撐肋30...蓋體31...頂部32...下開口34...連結部342...外凸垣343...內凸垣344...第一凸塊345...第二凸塊346...第三凸塊347...轉角348...卡接塊35...分隔肋
