## Abstract

A device for applying a fluid, gel-like, pasty or powder product, in particular a cosmetic product, comprising an applicator held on a wand, a container for storing the product and for receiving the applicator in a rest position, and a wiper which in the rest position surrounds the wand in an annular shape in a contact region and bears thereagainst.

## Claims

### Claim 1

A device for applying a fluid, gel-like, pasty or powder product, in particular a cosmetic product, comprising:
a wand adapted to be received in a wiper, the wand comprising a first cylindrical contact region having a length L1 of constant diameter D, a first conical region extending from an end of the first contact region wherein the first conical region increases in diameter as it extends from the first contact region and has a length L2, wherein L2 is greater than L1, a second cylindrical intermediate contact region having a length L3 extending from an end of the first conical region and having a constant diameter D′, wherein L3 is less than L1 and D′ is between 1.5 and 2.5 D, and a second conical region extending from the second intermediate contact region wherein the second conical region decreases in diameter as it extends from the second cylindrical intermediate region, is at least hollow in part for receiving a portion of the applicator and has a length L4 wherein L3<L4<L1<L2;
the wiper which in the rest position has a contact portion which surrounds the first contact region of the wand and bears against the first contact region, wherein the diameter D of the first contact region of the wand is greater than and up to 2 times as great as an internal width W of the contact portion of the wiper when the wand is not fitted in the wiper; and
the contact portion of the wiper is formed of a first material and a second portion of the wiper is formed of a second material which is harder than the first material.

### Claim 2 (depends on 1)

A device as set forth in claim 1 wherein the outside diameter D of the wand in the first contact region is between 1.2 and 1.5 times as great at the internal width W of the wiper without the wand fitted therein.

### Claim 3 (depends on 1)

A device as set forth in claim 1 wherein the wand is flexible.

### Claim 4 (depends on 1)

A device as set forth in claim 1 wherein the wiper includes thermoplastic material.

### Claim 5 (depends on 1)

A device as set forth in claim 1 wherein the wiper includes at least one substance selected from the group consisting of:
styrene block polymers,
polyester elastomers,
polyurethane elastomers,
soft polyolefin thermoplastic materials, and
thermoplastic polyamide.

### Claim 6 (depends on 1)

A device as set forth in claim 1 wherein the wiper has a TPE blend with a thermoplastic matrix and elastic particles.

### Claim 7 (depends on 1)

A device as set forth in claim 1 wherein the wiper has PP-EPDM, PP-NR, PP-IIR blends and/or polyolefin thermoplastic materials.

### Claim 8 (depends on 1)

A device as set forth in claim 1 wherein the first and second portions of the wiper are joined together in an indenting relationship.

### Claim 9 (depends on 1)

A device as set forth in claim 1 wherein the first and second portions of the wiper are integral with each other.

### Claim 10 (depends on 1)

A device as set forth in claim 1 wherein at least one of the first and second portions of the wiper are integral with the container.

### Claim 11 (depends on 1)

A device as set forth in claim 1 wherein the applicator means is of a non-rotationally symmetrical configuration with respect to the container axis.
