## Abstract

A device of axis X for packaging a cosmetic product, includes a base defining a storage compartment and a lid mounted movably in rotation on the base between a closed configuration of the device and an open configuration of the device, a receptacle being arranged in the storage compartment and the lateral wall of the receptacle includes an elastically deformable material.

## Claims

### Claim 1

A device for packaging a cosmetic product, comprising:
a base defining a storage compartment, the base having a central axis;
a lid mounted movably in rotation on the base about an axis of a hinge between a closed configuration of the device and an open configuration of the device; and
a receptacle containing the product P, delimited by a bottom, an upright wall, and by a lateral wall having a concave central portion, being arranged in the storage compartment, the receptacle being fixed relative to the base,
wherein the lateral wall of the receptacle comprises an elastically deformable material and a width of the lateral wall is configured to increase through the effect of the base and the lid being brought closer together, forming a sealing gasket coming into contact with the lid in the closed configuration of the device,
wherein in the closed configuration, an internal wall of the lid contacts an external surface of the lateral wall,
wherein the concave central portion is located on an internal portion of the lateral wall that faces in a direction of the central axis of the base,
wherein the upright wall defines a groove at an upper end of the upright wall, and
wherein the lateral wall includes an upper edge positioned within the groove of the upright wall.

### Claim 2 (depends on 1)

The device according to claim 1, wherein the lateral wall of the receptacle is a continuous solid wall having a circular, oval or parallelepipedal cross section with corners defining an inwardly curved profile.

### Claim 3 (depends on 1)

The device according to claim 1, further comprising: a closure device for holding the device in the closed configuration.

### Claim 4 (depends on 1)

The device according to claim 1, wherein the lid is transparent.

### Claim 5 (depends on 1)

The device according to claim 1, wherein the device is configured to cause a pop-up effect upon opening.

### Claim 6 (depends on 1)

The device according to claim 1, wherein the receptacle is fastened in the storage compartment or is a refill.

### Claim 7 (depends on 1)

The device according to claim 1, wherein the lid is provided with an interior skirt capable of coming into contact with the lateral wall in the closed configuration of the device.

### Claim 8 (depends on 1)

The device according to claim 1, wherein the receptacle is formed by a cup connected by the lateral wall to a support piece.

### Claim 9 (depends on 1)

The device according to claim 1, wherein the receptacle is fastened to the base by clicking, snap-fitting, screwing or force-fitting.

### Claim 10 (depends on 1)

The device according to claim 1, wherein the product is a foundation, a face-care product, a blusher, an eyeshadow, a lipstick, a lip gloss or a lip balm.

### Claim 11 (depends on 1)

The device according to claim 1, wherein the lateral wall of the receptacle is a continuous sold wall having a triangular, rectangular or square section, and
wherein corners of the receptacle define an inwardly curved profile.

### Claim 12 (depends on 1)

A cosmetic method comprising the steps consisting in:
(i) providing a cosmetic device according to claim 1,
(ii) opening the lid in order to slacken off the lateral wall of the receptacle, and
(iii) closing the lid in order to compress the lateral wall of the receptacle and to bring the lateral wall into contact with the lid.
