ABSTRACT:
A squeezable container for dispensing foamed sol which includes a container body and a nozzle assembly adapted to be connected together by means of threads. The nozzle assembly comprises an internally threaded outer cap member and a double-walled threaded inner cap member for threaded connection together. The double-walled inner cap member includes an outer cylinder having threads on the opposite sides for threaded engagement with the container body and the outer cap member, respectively and an inner cylinder surrounded by the outer cylinder in peripherally spaced relationship thereto to define an air flow passage serving as a check valve for introducing replaceable air into the container body. A pipe joint having an opening, a fluid flow-out pipe and a porous member are coaxially positioned one upon another within the inner cap member inner cylinder whereby the air from the head space in the container body is passed through flow grooves provided in the inner cap member inner cylinder or in the pipe joint into the porous member and the foamable liquid from the container body is passed through the flow-out pipe and the opening in the pipe joint to mix with the air in the porous member. The ratio of the cross-sectional area of the opening in the pipe joint to the sum of the cross-sectional area of the flow-out passages is within the range of 0.2-0.7.
