Abstract

A dispensing package for a consumer care product is provided having a product chamber with an inner surface, a major axis and a minor axis. The dispensing package has a movable elevator platform having a coupling sleeve with a non-threaded section and a threaded section along an inner surface. The dispensing package also has a screw assembly with a spindle that supports threads; a seal extending around the circumference of the spindle; a threaded first portion coupled to the threaded section along the inner surface of the moveable elevator platform; and a non-threaded second portion. The seal frictionally engages with the non-threaded section of the coupling sleeve and the movable elevator platform advances along an axis from a first fill volume position to a second fill volume position.

First claim

What is claimed is:

1 . A dispensing package, for a consumer care product, comprising:
a product chamber comprising;
an inner surface, a major axis and a minor axis;
a movable elevator platform comprising:
a coupling sleeve having a non-threaded section and a threaded section along an inner surface;
a screw assembly comprising:
a spindle that supports threads;
a seal extending around the circumference of the spindle;
a threaded first portion coupled to the threaded section along the inner surface of the moveable elevator platform; and
a non-threaded second portion;
wherein the seal frictionally engages with the non-threaded section of the coupling sleeve, and the movable elevator platform advances along an axis from a first fill volume position to a second fill volume position.

2 . The dispensing package of claim 1 wherein the non-threaded section of the elevator platform is at the lower end of the inner surface of the coupling sleeve and the threaded section is at the upper end of the inner surface of the coupling sleeve.

3 . The dispensing package of claim 1 wherein the elevator platform further comprises a rim that is in frictional contact with the inner surface of the product chamber along the product chamber major axis and minor axis.

4 . The dispensing package of claim 1 wherein the seal extends beyond the outer surface of the spindle.

5 . The dispensing package of claim 1 wherein the seal has a first diameter and the inner surface of the non-threaded section of the coupling sleeve has a second diameter, wherein the first diameter is greater than the second diameter.

6 . The dispensing package of claim 1 further comprising a rachet platform wherein the non-threaded second portion of the spindle extends from the ratchet platform to the seal for a distance of about 5 mm to about 45 mm.

7 . The dispensing package of claim 1 wherein the spindle is molded integrally with the screw base.

8 . The dispensing package of claim 1 wherein the first fill volume position provides a composition volume from about 15 ml to about 60 ml.

9 . The dispensing package of claim 8 wherein the second fill volume position provides a composition volume from about 70 ml to about 200 ml.

10 . The dispensing package of claim 1 wherein the screw assembly is molded from a polymeric material selected from the group consisting of polypropylene (PP), polyethylene (PE), polystyrene (PS), polyethylene-terepthalate (PET), styrene-acrylonitrile copolymer (SAN), polyethylene-terepthalate copolymers, polycarbonate (PC), polyamides, acrylonitrile-butadiene-styrene ( ), thermoplastic elastomers, polyoxymethylene copolymer and mixtures thereof.

11 . The dispensing package of claim 1 wherein the consumer care composition is disposed in the product chamber and comprises an antiperspirant composition.

12 . The dispensing package of claim 1 wherein the consumer care product comprises a top fill product.

13 . The dispensing package of claim 1 wherein the frictional engagement of the seal is maintained for a distance corresponding to a distance that the movable elevator platform moves along the axis from a first fill volume position to a second fill volume position.

14 . The dispensing package of claim 13 wherein the distance is from about 0.1 inch to about 1.0 inch.
