DUAL-CHAMBER CONTAINER

WIPO Patent Application WO/2010/082649

A1

A dual-chamber container of two-liquid mixing type, configured so that a discharge opening is opened in response to opening of a partition wall, wherein the discharge opening is adapted to be more reliably opened when the partition wall is opened. A discharge opening (12) of a synthetic resin formed product is provided with a tab (28) which serves as an opening/closing section and is located at the upper wall surface of an extension section (12-2) extended to the inside of a medication bag. The outer periphery of the tab (28) is, together with the remaining portion of the discharge opening (12), formed integrally with a thin-walled section (30) which serves as a weak section. A spring (40) is disposed within the discharge opening (12), and when the discharge opening (12) is in a closed state, the spring (40) is in a contracted state in which the spring applies to the tab (28) elastic force acting in the opening direction. The thin-walled section (30) is broken by inflation of the medication bag occurring when two liquid are mixed, and this opens the tab (28) to cause a medication in the medication bag to be introduced into the discharge opening (12). The elastic force of the spring (40) promotes the breakage of the thin-walled section (30).
