Rotary Airless Compact

摘要

A rotary airless compact including facing concentric arcuate inner and annular outer walls which are manually rotatable relative to each other, and a flexible tube extending between the walls and secured to the inner wall. The outer wall has radial ribs projecting inwardly to crimp the tube at spaced locations against the inner wall, providing successive seals between which the tube has internally open regions for holding fluid product. As the outer wall rotates relative to the inner wall in a direction from a first to a second end of the tube, product is drawn from a supply pouch at the first end into successive open regions of the tube in discrete quantities separated by the seals, and the ribs advance the seals and open regions to the second end, where a nozzle or other dispensing element discharges the quantities of product into a pan area of the compact.

主权项

1. A rotary airless compact for a fluid cosmetic or skin care product, comprising:
a compact body defining a pan area and including an arcuate inner wall and an annular outer wall disposed in facing concentric relation and manually rotatable relative to each other; a flexible tube extending between the walls, secured to the inner wall and having first and second ends with means adjacent the second end, communicating with the pan area, for dispensing fluid product from the tube into the pan area; and a supply pouch for fluid product communicating with a first end of the tube,wherein the outer wall bears spaced radial ribs projecting inwardly to crimp the tube at spaced locations against the inner wall, providing successive seals between which the tube has internally open regions for holding product, such that as the outer wall rotates relative to the inner wall in a direction from the first end toward the second end of the tube, product is drawn from the supply pouch at the first end into successive open regions in discrete quantities separated by the seals, and the ribs advance the seals and open regions to the second end, where the dispensing means discharges the quantities of product into the pan area.
