BLOW-MOLDED PLASTIC VESSEL FOR LIQUID MEDICINE

摘要

A blow-molded plastic vessel (1) of a so-called "natural drop type" which is deformed at a barrel part thereof for pouring liquid medicine, enables liquid medicine to collect in a large quantity at the time of natural drop of contained liquid, and is free of dead space possibly formed by deformation resulting from back pressure. The vessel (1) is characterized by being composed in such manner that: a flat barrel part (2) whose width at cross-section along the longer axis is two times that along the shorter one or larger; a suspending part (4) is formed on the upper edge of said barrel part (2) and a mouth part (6) is at the center of the lower edge (5) of said barrel part (2), and the surfaces in parallel with the shorter axis at lower cross-section of the barrel part (2) is each formed like a wedge whereas those in parallel with a longer axis like a funnel tapering toward the mouth part (6).
