## Abstract

A lipstick article is provided which houses a lipstick with a water content of from 0.5 to 30% by weight. The lipstick is packaged in a casing including a base, an elongated cylindrical inner body received in the base and containing the lipstick, a device for elevating-retracting the lipstick from within the inner body, a hollow elongated cap fitting over the inner body, and a hollow elongated plug sleeve inserted within the cap and formed of a material more flexible than a material forming the cap, the plug sleeve sealingly contacting an outer wall of the inner body to prevent evaporation of water from the lipstick.

## Claims

### Claim 1

A lipstick article comprising:
(i) a lipstick with a water content of from about 0.5 to about 30% by weight;
(ii) a package base;
(iii) an elongated cylindrical inner body having a lower portion received in said package base and said lipstick being received in said inner body;
(iv) a means for elevating and retracting said lipstick within said inner body, said means being formed therewithin, and said inner body including a cup bearing said lipstick, said cup having at least one aperture in a bottom thereof, and further comprising a means below said aperture for sealing said aperture when said cup is in a retracted position;
(v) a hollow elongated cap formed with an outer wall fitting over and covering said inner body; and
(vi) a hollow elongated plug sleeve inserted within said cap, stretching more than halfway along a length of said cap outer wall and formed of a material more flexible than a material forming said cap, said plug sleeve sealingly contacting an outer wall of said inner body to prevent evaporation of said water from said lipstick and said plug sleeve having a water vapor transmission rate at 37.8.degree. C./24 hours of at most 5 g-mm/mm.sup.2 under ASTM Method E-96-E.

### Claim 2 (depends on 1)

An article according to claim 1 wherein said water vapor transmission rate is at most 0.2 g-mm/mm.sup.2.

### Claim 3 (depends on 1)

An article according to claim 1 wherein said plug sleeve has an inner wall and at an open end thereof is formed with a taper along the inner wall.

### Claim 4 (depends on 3)

An article according to claim 3 wherein said plug sleeve has an inwardly projecting ring circumferentially along said inner wall between said taper and a closed end of said plug sleeve.

### Claim 5 (depends on 1)

An article according to claim 1 wherein said sealing means is an elastomeric insert.

### Claim 6

A lipstick article comprising:
(i) a lipstick with a water content of from about 0.5 to about 30% by weight;
(ii) a package base;
(iii) an elongated cylindrical inner body having a lower portion received in said package base and said lipstick being received in said inner body;
(iv) a means for elevating and retracting said lipstick within said inner body, and said means being formed therewithin;
(v) a hollow elongated cap fitting over and covering said inner body; and
(vi) a hollow elongated plug sleeve inserted within said cap and formed of a material more flexible than a material forming said cap, said material of said plug having a water vapor transmission rate at 37.8.degree. C./24 hours of at most 5 g-mm/mm.sup.2 under ASTM Method E-96-E, said plug sleeve sealingly contacting an outer wall of said inner body to prevent evaporation of said water from said lipstick.
