## Abstract

A device (10) for packaging and applying a pasty product, notably a cosmetic product, comprising: a case (14); an external protective shell (30) mounted on the case (14) and provided on the interior surface thereof with at least one helical groove (36); a tubular element (40) mounted to rotate freely in said external protective shell (30), while being held axially relative to said shell and provided with at least one longitudinal groove (42); and a cup (20) supporting a stick (12) of product mounted to slide in said tubular element (40). The cup (20) comprises a lower cup (22) carrying the stud (23) and an upper cup (24) carrying the stick (12) of product and comprising an axial projection (24c) extending axially toward the base of the case (14) through an orifice (22d) provided on the lower cup (22), said lower and upper cups (22, 24) being integral via a “push-push” latch locking/unlocking system (50).

## Claims

### Claim 1

A device (10) for packaging and applying a stick (12) of product, notably a cosmetic product, comprising:
a case (14);
an external protective shell (30) mounted on the case (14) and provided on the interior surface thereof with at least one helical groove (36);
a tubular element (40) mounted to rotate freely in said external protective shell (30), while being held axially relative to said shell and provided with at least one longitudinal groove (42); and
a cup (20) for supporting the stick (12) of product mounted to slide in said tubular element (40) between a storage position, in which the stick (12) is at least in part accommodated inside the tubular element (40), and a use position, in which at least a part of the stick (12) projects from the external shell (30), the cup comprising at least one stud (23) engaged in the helical groove (36) and the longitudinal groove (42):
the cup (20) comprising a lower cup (22) carrying the stud (23) and an upper cup (24) carrying the stick (12) of product, one of the upper cup (24) and the lower cup (22) comprising an axial projection (24c) extending axially toward the other of the upper cup (24) and the lower cup (22), and the device comprising:
a system (50) for locking/unlocking the upper cup (24) with the lower cup (22) movable between a locked position, in which the axial projection (24c) interacts with said system (50), and an unlocked position, in which the axial projection (24c) is free relative to said system (50), wherein said system (50) can be actuated from the unlocked position toward the locked position and vice versa via axial movement of the upper cup (24) toward the lower cup (22), and wherein the locking/unlocking system (50) comprises a casing (52) mounted on the lower cup (22) and a slide (54) arranged and movable axially in said casing (52), said slide (54) comprising at least two jaws (54a) that can move between the unlocked position, in which the axial projection (24c) is free relative to said jaws (54a), and the locked position, in which the axial projection (24c) is blocked axially between the jaws (54a), the movement of the jaws (54a) being obtained via the sliding of the slide (54) in the casing (52).

### Claim 2 (depends on 1)

The device (10) as claimed in claim 1, wherein the casing (52) of the system (50) is directly formed on the lower cup (22).

### Claim 3 (depends on 1)

The device (10) as claimed in claim 1, wherein the locking/unlocking system (50) comprises a guide lever (56) comprising a first end (56a) mounted in rotation on the slide (54) and a second end (56b), opposite the first end (56a), mounted in a groove (52c) made on the casing (52), said system (50) further comprising a return member (58) mounted between the base of the casing (52) and the slide (54) and configured such as to elastically stress the slide (54) toward the upper cup (24).

### Claim 4 (depends on 1)

The device (10) as claimed in claim 1, wherein the axial projection (24c) comprises, close to the free end thereof, a shoulder (24d) configured such as to interact with the jaws (54a) of the locking/unlocking system (50) in the locking position of said jaws (54a).

### Claim 5 (depends on 1)

The device (10) as claimed in claim 1, comprising a protective cap (29) fixed on the upper cup (24).

### Claim 6 (depends on 5)

The device (10) as claimed in claim 5, wherein the protective cap (29) is in axial contact on the upper cup (24), the axial movement of the upper cup (24) toward the lower cup (22) being produced by axial pressure on said protective cap (29).

### Claim 7 (depends on 1)

The device (10) as claimed in claim 1, wherein the lower cup (22) comprises an upper cylindrical wall (22a) comprising, on the external lateral surface thereof, at least one stud (23) projecting radially outward and a lower cylindrical guide skirt (22b) comprising an internal bore (22e) shaped such as to receive the locking/unlocking system (50).

### Claim 8 (depends on 7)

The device (10) as claimed in claim 7, wherein the lower cylindrical guide skirt (22b) ends at the free end thereof, in the form of an annular shoulder (22d).

### Claim 9 (depends on 1)

The device (10) as claimed in claim 1, wherein the axial projection (24c) has the form of a cylindrical rod.

### Claim 10 (depends on 1)

The device (10) as claimed in claim 1, wherein the upper cup (24) comprises a cylindrical skirt (24a) for receiving the stick (12) of product provided with a base (24b) at the lower end thereof and with the central axial projection (24c) extending axially from the base (24b) on the side opposite the stick (12) of product.

### Claim 11 (depends on 1)

A kit (60) for production of an assembly for packaging and applying a stick (12) of product, comprising, first, a device (10) for packaging and applying a product as claimed in claim 1, and, second, at least one refill (62) comprising an upper cup (24), a stick (12) of cosmetic product and a protective cap (29).

### Claim 12 (depends on 11)

The production kit (60) as claimed in claim 11, comprising at least two refills (62) mounted in a case (64).

### Claim 13 (depends on 1)

A method for insertion and removal of an assembly (28), comprising at least one stick (12) of product and an upper cup (24) in a device (10) as claimed in claim 1, wherein, upon insertion of the assembly (28) into the device (10), the assembly (28) is inserted in the tubular element (40) until the axial projection (24c) bears axially on the locking/unlocking system (50).

### Claim 14 (depends on 13)

The insertion and removal method as claimed in claim 13, wherein the axial bearing of the axial projection (24c) on the locking/unlocking system (50) causes the jaws (54a) to move into the locking position via axial movement of the slide (54) toward the base of the casing (52).

### Claim 15 (depends on 14)

The insertion and removal method as claimed in claim 14, wherein, upon removal of said assembly (28) from the device (10), axial bearing is exerted on the axial projection (24c) such as to cause the jaws (54a) to move into the unlocking position via axial movement of the slide (54) toward the upper cup (24).
