Rotary airless compact

A rotary airless compact for dispensing a fluid cosmetic or skin care product comprising:

• (a) a compact body including a top body part and a bottom body part snap-fitted together so as to be relatively rotatable about a central axis, the top body part defining a pan area and having an arcuate inner wall depending below the pan area, the bottom body part comprising an annular outer wall disposed in spaced concentric relation to the arcuate inner wall and bearing angularly spaced truncated radial ribs each projecting inwardly toward but stopping short of the arcuate inner wall;
• (b) a pan area floor mounted to the upper body part within the pan area and having a central hole;
• (c) a soft flexible tube extending around the inner wall between the inner wall and the ribs over an arc sufficient so that the tube simultaneously engages a plurality of the ribs, the tube being sealingly crimped by the ribs and having un-crimped portions between adjacent ribs for containing discrete quantities of fluid product, the tube having opposed inlet and outlet ends both fixed to the top body part and disposed within the lower portion of the top body part whereby the bottom body part is rotatable relative to the tube, the tube outlet end being sealed and having a nozzle opening through said central hole;
• (d) a flexible pouch cartridge for holding fluid product, disposed within the lower portion of the top body part and communicating with the tube inlet end for supplying fluid product thereto;
• (e) a flapper hinged to the top body part, receivable in the pan area and bearing a pintle for sealing the nozzle through the hole, and
• (f) a lid hinged to the top body part and having a closed position overlying the flapper.

A rotary airless compact for packaging and disposing a fluid cosmetic or skin care product, comprising

• (a) a flexible hollow tube for containing and transporting a fluid product to be dispensed by the compact, the tube having opposed first and second ends with means opening adjacent the second end for dispensing the fluid product from the tube;
• (b) a flexible receptacle for holding the fluid product, communicating through a seal with the first end of the tube for supplying the fluid product to the tube;
• and
• (c) a compact body including an arcuate inner wall and an annular outer wall concentrically surrounding and spaced from the arcuate inner wall, the inner and outer walls being connected so as to be manually rotatable relative to each other about a common axis, the opposed ends of the tube being secured to the inner wall whereby the tube rotates therewith relative to the outer wall, the tube extending for a substantial angular distance between the inner and outer walls in a direction of relative rotation thereof, and the outer wall bearing an array of angularly spaced truncated ribs projecting radially inwardly toward the inner wall and shaped and dimensioned for engaging the tube and crimping the tube against the inner wall to create a seal in the tube at each location of crimping with internally open regions in the tube between successive crimping locations, such that as the outer wall is rotated relative to the inner wall in a direction away from the first end of the tube toward the second end of the tube, successive crimping locations and internally open regions are created and moved along the length of the tube, and fluid product is drawn from the receptacle into the successive chambers as they are created, for delivery of discrete quantities of the fluid product from the receptacle to the dispensing means while maintaining the quantities of fluid product sealed in the successive chambers until they are discharged through the dispensing means.
