Abstract

The invention provides an eyedrops container which is easy to manufacture and easy to sterilize, ensures a sterile guarantee, and moreover is excellent in instilling operability, the eyedrops container is integrally formed of a resin material that does not melt or deform in time of sterilization performed under a condition of approximately 121 DEG C, for approximately 20 minutes.

Description

technical field [0001] The present invention relates to a medical eye drop container (hereinafter, simply referred to as an eye drop container) and an eye drop tool which store a medical eye drop freely. Background technique [0002] As an eye drop container filled with eye drops for medical use, such as Image 6 or Figure 7 The eye drop container shown. That is, the middle stopper 11 is installed on the container main body 10 formed into a hollow cylindrical shape, and if the lid is also included, the whole eye drop tool is constituted by three parts, thereby forming a so-called three-piece (ピ ス) eye drop container ( Image 6 ), or, the liquid injection cylinder part and the container main body are integrally formed by blow molding technology to form an integrally formed container ( Figure 7 ) is the so-called bottled eye drop container, and these two eye drop containers have been widely used. In this bottle-type eye drop container, a prescribed amount of a medical solu...
