WIPO Patent Application WO/2015/129594
Kind Code:
A1
Abstract:
[Problem] To provide: a drip-type package with which costs are kept sufficiently low by using a simple structure, and which does not become contaminated due to bacteria or the like adhering to a discharge opening thereof during distribution, etc., before use, and suppresses the entry of air and foreign substances once used, while in particular, allowing eye drops or the like to be precisely dripped as desired; and a drip-type packaging structure formed from said drip-type package and an elastic frame member. [Solution] This drip-type package is obtained by filling a liquid substance into a packaging bag in which a film-like discharge nozzle has a tapered discharge passage and is provided projecting from the upper end part of a packaging bag body. The film-like discharge nozzle has, near the tip end part thereof, a linear, bent, or curved seam for guiding tearing. The opening edge of the discharge passage is formed by cutting off the tip end section of the film-like discharge nozzle along the seam for guiding tearing, and has a linearly inclined shape or a shape that projects in a bent or curved line in the direction in which the film-like discharge nozzle projects.
