A dispensing unit which may be readily incorporated in an enclosure, such as a conventional can. The dispensing unit includes a readily collapsible bag in which a product to be dispensed is stored, and a plurality of spring strips. Each of the spring strips is of a construction to inherently roll into a coiled form and constantly urging the collapsing of the container. When the container is incorporated in an enclosure of the general can type including an upper end unit secured to a body by a seam, upper end portions of the spring strips may be anchored within the seam.
