ABSTRACT:
The present invention relates to a so-called "natural dripping" type plastic container by which medicinal fluids are administered by deformation of the flat shaped body. During natural dripping the accumulation capability for the contained fluids is large and the deformation based on back pressure avoids the occurrence of dead space. In the plastic blow container for medicinal fluids of this invention, in the cross-sectional shape of a flat shaped body the long axis width is more than 2.0 times the short axis width, at the upper end of the body a suspending mechanism is formed, and at the outer of the lower end of the body an opening means is formed, the bottom cross-section of the body on the short axis side the shape of parallel faces is formed as a wedge, while the parallel faces on the long axis side are formed with a tapered funnel shape toward the opening means.
