Document Type and Number:
WIPO Patent Application WO/2015/033507
Kind Code:
A1
Abstract:
Provided is a cell culture flask which has a simple structure and can prevent that the liquid contained in a topmost tray leaks unintentionally through the capillary effect and in which differences in the outer dimensions in individual products are eliminated from occurring; also provided is a manufacturing method thereof. This cell culture flask (100) comprises: an outer frame (200) which includes an outer bottom surface part, a rising outer circumferential wall provided around the entire perimeter of the outer bottom surface part, and a port (280) provided in a portion of the rising peripheral wall; an multi-stage inner tray (400) which is housed inside of the outer frame and which comprises multiple stacked inner trays which include an inner bottom surface part and a rising inner peripheral wall provided around the entire perimeter of the inner bottom surface part; a lid (500) which covers and fuses to both the top end of the rising outer peripheral wall and the top end of the rising inner peripheral wall of the topmost inner tray of the multi-stage inner tray; and a communication hole formed in the rising inner peripheral wall of each of the multi-stage inner trays so as to allow communication between the spaces in the inner trays and the space in the outer frame.
