Title:

LAMINATED RELEASABLE BOTTLE AND METHOD OF PRODUCING THE SAME

Document Type and Number:

WIPO Patent Application WO/2004/071887

Kind Code:

A1

Abstract:

A particularly small-sized instillator bottle or the like, arranged such that even in the lack of a check valve in an introduction hole, the introduction hole is easily blocked when the bottle barrel is squeezed, and the air between the inner and outer layers can be compressed, making it possible to easily make a confirmation test of the introduction hole for formation defects. To this end, a test hole (19) communicating with an introduction hole (17) through a space between an outer layer bottle (1) and an inner layer bag (16) is formed in an outer layer mouth (4), and the test hole (19) is blocked by an intermediate plug (21) and the inner layer bag (16) that are fitted in the mouth (4). Further, the introduction hole (17) is disposed in the middle of the barrel to be pressed by a finger during squeezing, so that the introduction hole (17) is blocked by the finger.
