ABSTRACT:
A culture vessel used for microorganism culture, cell culture, tissue culture and the like, which has features with regard to a shape of the opening neck for enabling to perform various operations such as introduction of a culture area solution and insertion of pipettes or the like. In the conventional culture vessel, the opening parts at the opening end of the neck and the connecting part joining the vessel body with the neck have been of circular shapes and they have diameters of equal dimension to provide a straight pipe configuration for the opening neck. This gives rise to the problems that a dead angle is formed for a culture area during operation. In the culture vessel according to the invention, the shape of inner peripheral wall of the opening end of the opening neck diameter of the inner peripheral wall of the connecting part is substantially the same as the diameter of the inner peripheral wall of the opening end, and a minimum diameter of the inner peripheral wall of the connecting part is 20 to 90% of the maximum diameter, whereby the abovementioned problems are solved.
