Description

[0037] The invention may be understood better on reading the following description, accompanied by nonlimiting implementation examples thereof, with reference to the appended drawings, in which:

[0038] FIG. 1 is an overall view, in longitudinal section, of a packaging, dispensing and application device according to the present application,

[0039] FIG. 2 is a view in longitudinal section of a case belonging to the device in FIG. 1,

[0040] FIG. 3 is a front view of the case in FIG. 2.

[0041] FIG. 1 shows a device 1 for packaging, dispensing and applying a makeup product in the form of a makeup pen, the cosmetic product being a stick of cosmetic product (not shown), in this case an eyebrow mascara.

[0042] The device 1 comprises a longitudinal tubular case 100, shown on its own in FIGS. 2 and 3. The case 100 has an open first end 101, intended for dispensing the cosmetic product, and an opposite second end 102, intended to be closed by a base 200.

[0043] The case 100 has a rectilinear internal duct 104, preferably of constant section, in this case elongate, extending in a longitudinal direction of said case 100, and in particular in the direction of a longitudinal central axis of an external envelope E1 of the first end 101, from said first end 101 to the second end 102 closed by the base 200.

[0044] The base 200 accommodates a mechanism for driving a support 103 for holding said cosmetic product in translation along the case inside the duct 104. Conventionally, the base 200 comprises an actuating part 201 that is prevented from moving in translation with respect to the case 100 but is rotatable. For its part, the support 103 is movable in translation and prevented from rotating with respect to this same case 100. A helical groove system 203 combined with one or more guide pins 205 converts the rotational movement of the actuating part of the base into a movement of the support 103 in translation so as to bring about the extension or retraction of the cosmetic product with respect to the case. In order to accommodate the rotary drive mechanism, the case 100 has, at its second end 102 closed by the base 200, a substantially circular and more generally rotationally symmetric overall section.

[0045] As explained above, the rotation of the actuating part 201 in a first direction drives the movable support 103 toward the open front end 101, and causes the cosmetic product to partially emerge from the case 100. Rotation of the actuating part 201 the other way drives said movable support 103 in the opposite direction, causing the product to retract into this same case 100.

[0046] In a complementary manner, the device 1 comprises a removable cap 106 intended to cover at least a front portion of the case 100 and configured to engage with an external envelope E2 of the device at the second end 102 of the case 100 or behind said second end 102 over an external envelope of the device 1 in the region of the driving base 200 for the support 103. The cap 106 has a cylindrical overall shape with a substantially constant circular internal section in a longitudinal direction of said cap 106. A longitudinal central axis of the cap coincides with a longitudinal central axis A2 of the external envelope E2 of the second end 102 of the case 100 when the cap is in place (FIG. 1).

[0047] According to the present application, the device 1 (apart from any cap) has, at the open first end 101 of the case 100, an external envelope E1 with a longitudinal central axis A1 offset radially with respect to a longitudinal central axis A2 of an external envelope E2 of the device 1 at the opposite end 102 of the case that is closed by the base 200.

[0048] The fact that the first end is off-center with respect to the second end and the base of said case, and thus of the longitudinal central axis of the cap 106 when it is in the closed position, thus frees up a larger lateral space L between a front lateral wall of the case 100 and an internal wall of the cover 106.

[0049] This lateral space L can be used to house a complementary application element 107 with greater dimensions compared with the existing prior out, both in terms of the height projecting from the case 100 and in width over the periphery of the case 100. More particularly, the complementary application element 107 could have a longitudinal size greater than 0.7 cm and/or a peripheral size greater than 0.5 cm.

[0050] The expression “at the end” is understood as meaning a longitudinal portion of the case that extends from said end over a sufficient distance to house the desired complementary application element. In particular, the longitudinal portion extends over at least 1 cm, preferably up to around 2 cm.

[0051] As can be seen in FIG. 3, an overall section of the external envelope E1 at the first end 101 is inscribed entirely within an overall section of the external envelope E2 at the second end 102.

[0052] In particular, the largest section of the device 1 along the case, determining notably the internal dimensions of the attached cap 106, is located at the second end 102. The smallest section of the device 100 is, for its part, at the open first end 101. The overall section of the external envelope of the device 1 decreases continuously along the case 100 from the second end 102 to the open first end 101. More specifically, the case 100 has a non-rectilinear lateral portion from the second end 102 to the first end 101, which forms a discontinuity forming a transition zone between the two, axially offset, external envelopes E1, E2.

[0053] In the particular case shown, the external envelope E1 of the case is substantially elongate, 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 A1, A2. With such an elongate section, a relatively large substantially flat lateral surface is thus available for housing the desired complementary application element 107.

[0054] As can also be seen in FIG. 3, a complementary section of the external envelope E1 of the device 1 at the open first end 101 of the case is substantially continuous and is mostly situated on the opposite side of the longitudinal central axis A1 of the external envelope E1 of the device 1 at said open first end 101 from the longitudinal central axis A2 of the external envelope E2 of the device 1 at the second end 102 closed by the base 200.

[0055] The complementary application element 107 protrudes laterally from a lateral wall of the external envelope E1 substantially in the direction of the offset between the longitudinal central axes A1, A2 and from the central axis A1 of the first end 101 to the central axis A2 of the second end 102. More specifically, the complimentary application element extends within the complimentary section and notably in the continuous part situated on the opposite side of the longitudinal axis A1 from the axis A2.

[0056] In the present case, the complementary application element 107 is a brush comprising a set of spikes 108 arranged in a plurality of longitudinal rows over a peripheral portion of the external envelope E1. Of course, numerous other configurations are possible given the available space L.

[0057] This complementary application element 107 of the brush type can notably make it possible to homogenize and smooth the product applied to the eyebrows or even to remove the excess.

[0058] As regards the drive mechanism and the support 103, said support 103 comprises, on one side, a front cup 103a, intended to support the stick of cosmetic product and to push it through the duct 104, and, on the other side, an anchor 103b bearing the guide pins 205 in the helical groove 203. The cup 103a and the anchor 103b are connected by a rod 103c or stem that is long enough to cover the travel of the cup 103a along the duct 104 and consequently of the anchor 103b along the groove 203.

[0059] The cup 103a is aligned with the longitudinal central axis of the duct 104, coinciding substantially with the central axis A1, while the anchor 103b is substantially aligned with the longitudinal central axis A2 of the second end 102. On account of the misalignment between the central axis A1 and the central axis A2, the rod 103c cannot be aligned with either of these two axes.

[0060] According to a first embodiment as shown in FIG. 1, the rod 103c is rectilinear but secured to the cup 103a and the anchor 103b in a slightly off-center manner with respect to at least one or both of these elements depending on the respective dimensions and the size of the offset.

[0061] Alternatively, according to a second embodiment that is not shown, it is possible to realize a rod that has a sufficiently small thickness to have a degree of flexibility allowing slight deformation during the displacement. The rod can thus be connected to the cup 103a and/or to the anchor 103b at the centers thereof.
