An eye drops container including a container body filled with a drug solution along with a pressurized gas and including a valve mechanism discharging a fixed amount of drug solution; a nozzle member coupled with a stem for open operation of the valve mechanism and including a drug solution drop nozzle; an operating member including an operating piece and attached to the container body; a guide member contained in the operating member and guiding the nozzle member in the axial direction; and a ball contained in the guide member. The nozzle member includes an outer flange for suspending a skirt on the lower surface thereof; the guide member includes a ring-like bottom groove into which the forward end of the skirt enters; and the ball falls into the bottom groove in an upright state to block the open operation of the valve mechanism, and falls onto the outer flange in an inverted state to permit the open operation of the valve mechanism.

Eye drops container

A double chamber aerosol container capable of filling contents in the container has a container cap that constitutes a liquid container with an inner sack to be temporarily fitted to a bead portion of an outer container while the inner sack is placed within the outer container. When the inner sack is placed with the outer container, the lower end of the inner sack is not in contact with the bottom of the interior of the outer container. The propellant is filled in the outer container upon forming a filling gap between the container cap and the bead portion, and then the container cap is surely clinched to the bead portion of the outer container.

Double chamber aerosol container and manufacturing method therefor

A double chamber aerosol container capable of filling contents in the container upon cutting off open air has an inner sack, whose volume is reducible according to reduction of contents, formed with temporarily engaging portions. A housing to which a valve assembly is arranged is inserted in the inner sack where the temporarily engaging portions are temporarily engaged with a ring-shaped neck portion of an outer container. After propellant is filled in a space between the inner sack 1 and the outer container during this temporarily engagement, the inner sack is inserted in the outer container to form the double chamber aerosol container.
