A collapsible bottle for enteral feed has a thin-walled body extending axially from a base to a neck and having a front, a back and two sides that define a width dimension of the bottle. The body has a shoulder region adjacent to the neck, a hip region adjacent to the base and a waist region therebetween and the circumference of the bottle in the waist region is less than the circumference of the bottle in both the hip region and the shoulder region. The bottle is provided with hinge columns that extend between the hip region and the shoulder region at the sides of the bottle. The hinge columns provide the wall of the body with a region of increased stiffness in the axial direction while facilitating bending of the wall about the hinge column. |
