## Abstract

Device for packaging, dispensing and applying a solid or pasty block of cosmetic product The present application relates to a device for packaging, dispensing and applying a block of solid or pasty cosmetic product, comprising a longitudinal tubular case having an open first end, intended for dispensing the cosmetic product, and an opposite second end that is closed by a base accommodating a mechanism for driving a support for holding said cosmetic product in translation along the case, characterized in that the device has, at the open first end of the case, an external envelope with a longitudinal central axis offset radially with respect to a longitudinal central axis of an external envelope of the device at the opposite end of the case that is closed by the base.

## Claims

### Claim 1

A device for packaging, dispensing and applying a block of solid or pasty cosmetic product, comprising:
a longitudinal tubular case having an open first end, intended for dispensing the cosmetic product, and an opposite second end that is closed by a base accommodating a mechanism for driving a support for holding said cosmetic product in translation along the case; and
an external envelope at the open first end of the case, the external envelope having a longitudinal central axis offset radially with respect to a longitudinal central axis of an external envelope of the device at the opposite end of the case that is closed by the base,
wherein the case bears, close to the open first end, at least one complementary application element protruding from a lateral wall of the external envelope in at least the direction of the offset between the longitudinal central axes from the central axis of the first end toward the central axis of the second end,
wherein the support for holding the cosmetic product is connected to the mechanism for driving in translation via a substantially rectilinear rod, a longitudinal axis of the rod is off-center with respect to a longitudinal axis of said support and to the drive mechanism.

### Claim 2 (depends on 1)

The device as claimed in claim 1, wherein a section of the external envelope of the device at the open first end of the case covers less than 70% of a section of the external envelope of the device at the second end of the case.

### Claim 3 (depends on 2)

The device as claimed in claim 2, wherein a complementary section of the external envelope of the device at the open first end of the case comprises a continuous zone that represents at least 80% of said complementary section.

### Claim 4 (depends on 3)

The device as claimed in claim 3, wherein the complementary section of the external envelope of the device at the open first end of the case is situated on the opposite side of the longitudinal central axis of the external envelope of the device at the open first end from the longitudinal central axis of the external envelope of the device at the base.

### Claim 5 (depends on 1)

The device as claimed in claim 1, wherein the case has a rectilinear internal duct, preferably of constant section, notably elongate, extending preferably in a longitudinal direction of said case.

### Claim 6 (depends on 1)

The device as claimed in claim 1, further comprising a removable cap configured to engage with the external envelope of the device at the base of the case or behind said base over the external envelope of the device in the region of the drive mechanism for the support.

### Claim 7 (depends on 6)

The device as claimed in claim 6, wherein the cap has an internal section that is substantially constant in a longitudinal direction of said cap, said longitudinal direction coinciding with the central axis of the second end of the case when the cap is in place.

### Claim 8 (depends on 1)

The device as claimed in claim 1, wherein the case has, at its opening, a substantially elongate section of external envelope, a major axis of said elongate section extending notably in a direction substantially perpendicular to the direction of the offset between the longitudinal central axes.

### Claim 9 (depends on 1)

The device as claimed in claim 1, wherein the case has, at its second end closed by the base, an external envelope of substantially circular section.

### Claim 10 (depends on 1)

The device as claimed in claim 1, wherein the support for holding the cosmetic product is connected to the mechanism for driving in translation via a rod that exhibits flexibility allowing slight deformation, said rod being connected to the holding support and to the drive mechanism substantially at their center.

### Claim 11 (depends on 1)

The device as claimed in claim 1, wherein the cosmetic product is a product for eyebrows.

### Claim 12 (depends on 1)

A method for making up the eyelashes or eyebrows, comprising:
a step of applying a makeup or care product in the form of a stick to the eyelashes or eyebrows by means of a device as claimed in claim 1.

### Claim 13 (depends on 12)

The makeup method as claimed in claim 12, further comprising:
a subsequent step of using a complementary application element of the device, the complementary application element protruding from the lateral wall of the external envelope in at least the direction of the offset between the longitudinal central axes from the central axis of the first end toward the central axis of the second end.
