(18) The lipstick refill of the invention is intended for the replacement of the stick of a lipstick mechanism which has the following features. Rather than driving the axial raising and descent of the stick in the sleeve by rotation of a rotary actuation ring, the lipstick mechanism M of the invention is simpler, since the axial raising and descent of the stick B is done by acting directly on an axial translative push-button which is integral with a cup in which the stick R is mounted.
(19) More specifically, as can be seen in
(20) The lipstick mechanism M of the invention also comprises a sheath F, closed at its upper end F1, which is removably engaged around the sleeve C. It can be held in place on the sleeve C by small relief profiles. The sheath F can come into contact with the projecting annular ridge C6. It can be noted that the lower edge of the sheath comprises a notch F2, which can be aligned with the window C1, such that it leaves the lower bottom C3 visible, when the sheath F is in place on the sleeve C.
(21) The lipstick mechanism M of the invention further comprises a refill entity 1, 2, 3 which is slidingly and removably mounted in the receiving sleeve C. This refill entity comprises a cup and a stick B mounted in the cup. The stick B can have a conventional shape, mainly cylindrical with a bevelled and rounded upper end. The lower end of the stick B is set in the cup. As can be seen below, the cup can have different embodiments G1, G2, G3. In
(22) According to the invention, the refill entity 1, 2, 3 forms an integral part of a lipstick refill R1, R2, R3 in association with a case E1, E2, E3 in which the refill entity is removably received. The stick B can be substantially identical in all embodiments and does not constitute a critical element of the invention, which is concentrated at the level of the cup G1, G2, G3 and of the case E1, E2, E3. Before describing in detail the various embodiments, it can first be noted that the lipstick refill R1, R2, R3, R4 of the invention integrates not only the stick B, but also the cup G1, G2, G3, which will serve to removably hold the refill entity 1, 2, 3 in the case E1, E2, E3 and enable the transfer of the refill entity to the receiving sleeve C of the lipstick mechanism M.
(23) In reference to
(24) This refill R1 first comprises a refill entity 1, constituted of a stick B set in a cup G1, which is associated with a case E1 in which the refill entity 1 is received and removably held in place.
(25) The stick B is presented in the form of a short stick of thick cosmetic product. Absolutely conventionally, the stick B can have a substantially ogival-shaped upper end cut by an inclined flat face. Its lower end is housed inside the cup G1, which comprises a substantially cylindrical side wall G11 and an optional bottom G12. The cup G1 also comprises a resilient blocking strip L1 disposed in a cut-out G13 formed in the side wall G11. This strip L1 is inclined outwards so as to project with respect to the side wall G11. In this embodiment, the strip L1 extends upwards and outwards. In a variant, the strip could also extend downwards and outwards. In the rest state, the blocking strip L1 is inclined outwards, but it is possible to shut it in the cut-out G13 by resilient deformation. This resilient blocking strip L1 supports a push-button P1 which itself also radially projects outwards from the external face of the strip L1. Thus, by radial pressing on the push-button P1, the strip L1 can be deformed so as to return it into the cut-out G13. This push-button P1 will also serve to move the refill entity 1 translationally in the sleeve C of the lipstick mechanism M described above. The stick B can be mechanically inserted inside the cup G1. In a variant, the stick B can be moulded or cast directly inside the cup G1.
(26) The case E1 internally defines a receiving space to house the refill entity 1 there at the same time. This case E1 comprises an upper section of reduced diameter E11 and a lower section E13 of increased diameter. These two sections E11 and E13 are connected by a shoulder E14. The upper end E12 of the case E1 is closed, while its lower end is open. It can be noted that the lower section E13 is formed with a longitudinal indentation E15 which can extend over all or some of the height of the lower section E13. This longitudinal indentation E15 is defined between two parallel side edges E16. The indentation E16 comprises an upper bottom E17, in this case disposed in the proximity of the shoulder E14, as well as a lower opening E18. It is therefore possible to introduce an element in the indentation E16 through its lower opening E18 and to make it slide until abutting against its upper bottom E17. Optionally, a narrowing E19 can be provided in the proximity of the bottom E11 of the indentation E15: the two side edges E15 can form two bosses oriented towards one another so as to create a localised tapering of the indentation E16 in the proximity of the upper bottom E17.
(27) According to the invention, the refill entity 1 is inserted inside the case E1 through the opening of its lower section E13, such that the push-button P1 passes through the indentation E16. The final mounting position is reached when the push-button P1 abuts against the upper bottom E17. It can be noted in
(28) The final mounting position of the refill entity 1 inside the case E1 is guaranteed by the abutment of the push-button P1 against the upper bottom E11 of the indentation E16. The blocking in final mounting position of the refill entity 1 inside the case E1 can be ensured either by the push-button P1 snap-fitted beyond the narrowing E19 of the indentation E15, or by the resilient pressing of the strip L1 against the lower wall of the lower section E13, or by the friction engagement of the upper end of the side wall G11 of the cup G1 inside the upper section E11. A combination of these different holdings is also possible.
(29) The cup G1 and the case E1 can be made of any suitable material. However, a metal, in particular aluminium or steel embodiment, is preferred. The push-button P1 can be made of one piece with the strip and the side wall G11 when the cup is made of plastic material. When made of metal, the push-button P1 can be returned on the strip L1 which is made of one piece with the side wall G11. Without moving away from the scope of the invention, it can be imagined that the internal wall of the case E1 is staged, but not its external wall. This can, in particular, be made of plastic material.
(30) Now,
(31) The longitudinal indentation E15 therefore makes it possible to fix the position of the refill entity 1 inside the case E1. The push-button P1 preferably abuts against the upper bottom E11 of the indentation E15. In a variant, the push-button P1 can be wedged between the two side edges E16 in the proximity of the upper bottom E17. A slight snap-fitting in the proximity of the bottom E11 can even be imagined, in order to block the push-button P1 inside the indentation 15. The visual alignment of the indentation E15 with the window C1 makes it possible for the user to very easily and rapidly transfer the refill entity 1 of the case E1 in the sleeve C.
(32)
(33) In this second embodiment, the refill R2 further comprises a slider K which can be presented in the form of a small cuff which is not complete, since it defines a passage K2. It can also be noted that the lower edge of the slider K can form a holding bead K1. This slider K is intended to be engaged around the cup G1 with the passage K2 receiving the strip L1. The slider K can also be inserted inside the case. Just like in the first embodiment, when the refill entity 1 is in place in the case, the push-button P1 is engaged in the indentation E25 until abutting against its upper bottom E27. Optionally, the side edges of the indentation E25 can progressively move closer to one another in the proximity of the upper bottom E27 to create a narrowing E29 in order to hold the push-button P1 in position by clamping or in the proximity of the bottom E27. The cup G1 and the strip L1 can be observed through the indentation E25, as can be seen in
(34)
(35) Just like in the first embodiment, an annular space is created to receive the sleeve C and engage the push-button P1 in the window C1 of the sleeve. Although the push-button A1 does not come into contact with the bottom C3 in these two embodiments, a variant can be considered in which the sleeve C has no bead C6, thus enabling the push-button P1 abutted against the bottom E11 of its indentation E15 to reach the bottom C3 of the sleeve.
(36) The case E2 with its slider K can be made of any suitable material, and preferably made of plastic material.
(37)
(38) The cup G2 is also adapted to receive a stick B to jointly form the refill entity 2. The latter is represented in
(39) In
(40) It must be noted that the movement of the cup G2 inside the sleeve C is done only by friction at the pins G23 and the resilient tabs G22. The push-button P2 is not intended to be sunk to release the movement of the cup G21, as was the case in the two first embodiments with the resilient blocking strip L1.
(41) In
(42) The fourth embodiment for a lipstick refill is represented in
(43) The cup G3 is preferably made by injection moulding plastic material, but it can also be made of metal. It receives a stick B to form a lipstick refill 3.
(44) In
(45) It must be noted that the resilient strip L3 is not stressed inside the case E3, such that it does not risk being deformed by creeping. The push-button P3 can be held in the indentation E35 by clamping between these side edges or also by a slight snap-fitting, as described above. The axial offsetting of the refill entity 3 inside the case E3 is not impeding, insofar as the sleeve C can, all the same, be inserted around the refill entity 3 thanks to the access profile G32 which avoids a direct abutment of the sleeve C against the cup G3.
(46) The four embodiments which have just been described make it possible to highlight two significant features which can be implemented independently, namely the indentation of the case, which makes it possible to house the push-button and the annular space between the refill entity and the case there, which makes it possible to engage the sleeve around the refill entity to collect it. The engagement of the push-button in the window of the sleeve C, while the push-button is also engaged at the bottom in the indentation of the case is another significant feature of the invention. Likewise, in all the embodiments, the annular space is passed through by the push-button. The push-button can simply abut against the bottom of the indentation and/or be blocked against the bottom or in the proximity of it by any suitable reversible blocking means, like a narrowing of the indentation, a thickening of the edge of the indentation, the pressing of the strip against the internal wall of the case, a friction between the cup and the case, etc. It has been seen that the cup can be made of metal or made of plastic material, with or without resilient blocking strip.
(47) Thanks to the invention, a lipstick refill is available, integrating a refill entity constituted of a cup and a stick which can be transferred from a case into the sleeve of a sliding lipstick mechanism without risk of contact with the stick. A box comprising a lipstick mechanism associated with several identical or different lipstick refill can, for example, be considered.
