ABSTRACT:
A liquid container comprises a flexible bag-shaped container body 1 which is provided with two flat portions 3(3a,3b) as front and back walls and two gusset portions 4(4a,4b) as side walls which are folded inwardly, and a pipe-shaped delivery unit 2 which is provided with a mouth portion 11 at an upper end thereof to be projected out of an upper end portion of the container body, and a flange portion 12 below the mouth portion to be held at a joining portion 5 of the upper end portion of the container body, wherein each gusset portion 4 has a width approximately equal to that of the flat portion 3, inward end portions 15(15a,15b) of the two gusset portions being interposed between the flange portion 12 and the flat portion 3 at the joining portion 5. When the liquid container is manufactured, it is preferable that films for the gusset portions are temporarily bonded to a film for the flat portion before the positioning of the delivery unit.
