Abstract
Disclosed is a disposable cell culture bag capable of facilitating cell culture by using a flexible transparent resin film, the disposable cell culture bag including a body having a sealed space for accommodating a medium, and made of a flexible transparent resin film usable for disposable products, and one or more tubing lines extending from an inside to an outside of the body, wherein the body includes a bottom-side integrated part provided by extending one or more side surfaces from a bottom surface of the body to be spread in a radial shape, in order to obtain continuously smooth four edges of the bottom surface, and a top surface fusion bonded to the side surfaces of the bottom-side integrated part after the side surfaces are fusion bonded to each other.
Claims8
A method of fabricating a disposable cell culture bag, comprising:
- folding up side surfaces of a bottom-side integrated part having a one-piece bottom surface and four rectangular side surfaces extending from the bottom surface, the bottom surface having a round shape and a unitary construction and being integrally formed with the one four rectangular side surfaces prior to bonding first bonding lines to one another, the first bonding lines being located at boundaries of the bottom-side integrated part, wherein the bottom-side integrated part is provided in a cross shape formed by the four rectangular side surfaces extending from the bottom surface without touching each other in combination with the bottom surface having the round shape;
- fusion bonding the first bonding lines to one another;
- fusion bonding a top surface to the four rectangular side surfaces of the bottom-side integrated part to thereby define a body having a sealed space for accommodating a medium and being made of a flexible transparent resin film used for disposable products;
- and
- arranging one or more tubing lines so that the tubing lines extend from outside of the body, through the top surface to an inside of the body.
