Abstract

A cosmetic dispenser with an inner body rotatably engaged with a spiral member. An elevator cup retains a cosmetic pomade, and the spiral member has spiral formations along an inner surface thereof for engaging lugs of the elevator cup that pass through longitudinal tracks in the inner body. The inner body can have lateral and longitudinal bearing surfaces with the lateral bearing surface aligned longitudinally with a longitudinal axis of relative rotation of the spiral member and the inner body and the longitudinal bearing surface orthogonal thereto. Fingers can project inwardly from the inner body to be in slidable, frictional contact with both the longitudinal and lateral bearing surfaces so that the fingers are restrained laterally and longitudinally. The fingers can be inwardly angled establish an effective circumference with the fingers tangent thereto smaller than the circumference of the lateral bearing surface.

2. The cosmetic dispenser of claim 1 wherein the first annular bearing surface has a diameter and a circumference and wherein the plurality of fingers establish an effective circumference with the fingers tangent thereto smaller than the circumference of the first annular bearing surface.

3. The cosmetic dispenser of claim 2 wherein the plurality of fingers are inwardly angled to establish the effective circumference with the fingers tangent thereto smaller than the circumference of the first annular bearing surface.

4. The cosmetic dispenser of claim 1 wherein the second annular bearing surface is generally concentric with and generally orthogonal to the longitudinal axis of relative rotation.

5. The cosmetic dispenser of claim 1 wherein the first annular bearing surface has a diameter and a circumference and wherein the plurality of fingers establish an effective circumference with the fingers tangent thereto smaller than the circumference of the first annular bearing surface.

6. The cosmetic dispenser of claim 1 wherein the plurality of fingers project from the spiral member and wherein the first and second annular bearing surfaces are retained relative to the inner body.

7. A cosmetic dispenser with frictional resistance for retaining a cosmetic pomade for extension and retraction, the cosmetic dispenser comprising:

an inner body with a proximal end, a distal end, a body portion, and at least one longitudinal track that communicates along a substantial length of the body portion;

an elevator cup for retaining a pomade of cosmetic, the elevator cup comprising an annular peripheral wall, a base portion, and at least one lug that projects outwardly from the peripheral wall;

a spiral member with a proximal end, a distal end, and a body portion with at least one spiral formation along an inner surface thereof for engaging the at least one lug of the elevator cup wherein the spiral member and the inner body are rotatably engaged with a longitudinal axis of relative rotation with the body portion of the inner body received into the body portion of the spiral member;

a first annular bearing surface retained by the inner body and a second annular bearing surface retained by the inner body adjacent to the first annular bearing surface wherein the first annular bearing surface is disposed at a non-zero angle relative to the second annular bearing surface;

a plurality of fingers that project from the spiral member wherein the fingers are in slidable contact with both the first and second annular bearing surfaces whereby the fingers are restrained by the first annular bearing surface in a first direction and by the second annular bearing surface in a second direction;
