Abstract
A dispensing container is produced from a disposable flexible, collapsible inner container surrounded by a resilient outer container. A dispensing cap assembly is removably coupled to the outer container to define a dispensing outlet for the contents of the inner container. The dispensing cap assembly includes a cap having an outlet coupled to the inner container. The inner container is attached to a support hanger which in turn is supported by the outer container. The cap has a dispensing outlet coaxially disposed with the outlet of the inner container. A dispensing check valve is provided in the cap assembly to allow the material to be dispensed without air being drawn into the container at the end of the dispensing cycle. The contents of the inner container are dispensed by squeezing the outer container to deform the side walls and create an increased pressure within the outer container causing the contents to be expelled through the dispensing check valve. The side walls are then allowed to relax which draws air into the container through air inlet check valve. The support hanger includes a depending skirt extending about midway into the outer container. The inner container is attached to the lower end of the skirt and at the upper end of the hanger.
