Apparatus for floating animal cells in a double-bag container

An apparatus for floating animal cells in a culture liquid comprising:

• a culture container, wherein said culture container comprises;
• an outer bag means for sealing a culture liquid and a volume of gas, said outer bag means comprising a pair of plastic sheets sealed at circumferential parts thereof and plastic tubes secured between the sealed circumferential parts for injecting culture liquid and a volume of gas,
• an inner bag means for supporting animal cells to be cultured under a condition wherein animal cells float in a culture liquid, said inner bag means comprising a pair of semipermeable film sheets sealed at circumferential parts thereof, said film sheets having pores of a sufficient size so as to prohibit cells within the inner bag from passing therethrough but allowing culture liquid and air to pass through it, and a plastic tube secured between the sealed circumferential parts of said inner bag means and said outer bag means for injecting a cell suspension, and
• a protective plastic mesh surrounding said inner bag means so as to prevent said inner bag means from contacting said outer bag means.
