ABSTRACT:
An improved liquid transfusing bottle made of flexible material of the type using no air venting needle. It includes a barrel portion, a shoulder portion and a bottom portion and parting lines extend on both the side faces in the vertical direction. The barrel portion is formed with ribs or recessed area of which contour line is so designed that a distance as measured from the parting line decreases toward the center part of the bottle from the shoulder portion or the bottom portion. As a residual volume of liquid in the bottle decreases, the barrel portion is deformed in the flattened configuration along the contour lines of the ribs or the recessed parts in such a manner that the shorter diameter thereof is reduced. Deformation of the barrel portion is achieved without any occurrence of twisting, breaking or the like of the bottle and liquid in the bottle is smoothly discharged therefrom at a constant speed during operation of transfusion.
