PROBLEM TO BE SOLVED: To provide a blow tube container made of a synthetic resin in which a degree of a projection to the side of a bottom seal part is small, and a storing capacity for a content liquid is large, by making the lateral width of the bottom part formed by fusing of the bottom seal part, and relaxing an effect of a flat posture holding force of the bottom seal part to a body cylinder. SOLUTION: An open cylinder part 11 whose opening part on the top end is tightly closed is stood on the top end of the body cylinder 1 through a shoulder part 8. The bottom part 2 is composed by flatly crushing the lower end of the body cylinder 1 from the front and back direction and forming it by fusing to the bottom seal part 3 under a condition where both side parts of the lower end part of the body cylinder 1 are folded inward to form folded parts 4. Gore sections 5 are formed by the folded parts 4. The lateral width of the bottom seal part 3 is made small by folding of the folded parts 4. The front and back width of the bottom part 2 is made large by a restoring elastic force of the gore sections 5 folded and formed. COPYRIGHT: (C)2005,JPO&NCIPI
