A tissue culture vessel structure is characterized in that: the culture culture vessel comprises a box body and a cover body, and the inner lower section of the box body is a resisting section extending a plurality of paths, so as to facilitate a moderate interval between the plurality of stacks. And easy to access, and the periphery of the upper end of the box body is formed to form a downwardly outwardly inclined abutting section, and the abutting abutting section is extended to extend a protruding section to match the aforementioned cover body. The limiting portion extending downwardly abuts against the inner side of the upper end of the casing and the hook portion formed inwardly from the lower periphery resists the protruding portion extending downward in the casing, so that the seedling is conveniently placed or taken out. In operation, the preset portion at the upper end of the cover body is recessed into a space and at least one or more through holes are formed, so that the tissue culture vessel can maintain a moderately ventilated pressure regulation when entering the culture liquid into the sterilization kettle, and the upper end of the cover body is provided. The upturned section allows the recessed area at the bottom of the stacking top to remain smoothly spanned.一種組織培養器皿結構，是採以：沿該組織培養器皿是包含一盒體、及一蓋體，前述盒體內部靠下段落是延伸數道的抵制段，以利多個堆疊時的適度間隔開及容易取用，及在盒體的上端周邊是朝外形成漸下外傾的抵靠段落，並使該截外傾的抵靠段落靠下是延伸一凸出段，以配合前述蓋體相應部位朝下延伸的限位部抵靠在盒體的上端周邊內側、及靠下周邊朝內形成的勾部抵制在盒體朝下延伸的凸出段，以利種苗在置入或取出具便利操作，另在蓋體上端預設部位是凹入一空間並形成至少一或以上的通孔，以利組織培養器皿在盛入培養液進入殺菌釜能保持適度透氣調壓，及使蓋體上端的上傾段落能允許堆疊頂端的盒體底部凹入的區域保持平穩跨設。
