Description

Technical Field

[0001] This invention relates to a lipstick refill component comprising a cup-shaped member and a lipstick stick housed within the cup-shaped member, thereby collectively forming a refill component body. The refill component also includes a housing in which the refill component body is held in place but is removable. The refill component body is intended to be transferred from the housing into a lipstick mechanism including a receiving sleeve adapted to slidably receive the refill component body. The receiving sleeve has the feature of forming a longitudinal window in which a button on the cup-shaped member can be manually moved to allow the lipstick stick to retract from or enter the receiving sleeve. Background Technology

[0002] In the prior art, document US2770358 is known, which describes this type of lipstick mechanism having a receiving sleeve forming a longitudinal window, through which a button on a cup-shaped component can be manually moved. The user places the lipstick stick, packaged in a pouch, into the cup-shaped component of the lipstick mechanism. It is noteworthy that the longitudinal window of the receiving sleeve is open at its lower end and forms a bottom at its upper end. The longitudinal window forms a notch, and the button on the cup-shaped component includes two small strips that can be resiliently placed together between the thumb and forefinger to release and move the cup-shaped component into the sleeve.

[0003] The disadvantage of this pouch-packaged refill is that once the pouch is opened, it's difficult to operate the refill without touching the lipstick stick with your fingers. Additionally, it's not easy to insert the lipstick stick into the cup-shaped part. Therefore, the replacement process is both messy and difficult.

[0004] In the prior art, document FR1124179A is also known, which describes a replacement part including a cup-shaped component with lugs that engage in vertical slots formed in a protective shell. These lugs are not intended for user operation but simply engage in two recesses (axial and helical) in the lipstick mechanism. This document essentially specifies removing the shell (cap) before engaging the cup-shaped component in the mechanism to insert the lugs into the recesses. Therefore, contact with the lipstick stick is unavoidable. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of the prior art by providing a lipstick replacement component that avoids any contact with the lipstick stick and is easy and reliable to place in the lipstick mechanism.

[0006] To this end, the present invention proposes a lipstick replacement part, comprising a cup-shaped part, a lipstick stick, and a housing, wherein the lipstick stick is accommodated in the cup-shaped part to jointly form a replacement part entity, and the replacement part entity is fixedly and detachably accommodated in the housing, the housing forming a longitudinal groove, characterized in that the cup-shaped part is provided with a button that protrudes radially outward from the outside of the housing through the longitudinal groove.

[0007] The longitudinal groove serves several functions. Firstly, it prevents the replacement part from being moved within the housing. In effect, the engagement of the button in the groove significantly reduces the button's freedom of movement within the housing. Secondly, the groove allows visibility of the button's positioning for placement within the longitudinal window of the lipstick mechanism's receiving sleeve. The user can easily align the longitudinal groove with the longitudinal window to prepare for the transfer of the replacement part. The user then presses the button to move it from the longitudinal groove within the lipstick mechanism. Thus, the button constitutes a dedicated component for the transfer of the replacement part within the lipstick mechanism.

[0008] A particularly interesting feature of the invention is that a substantially cylindrical annular space can be defined between the replacement body and the housing. This annular space allows the receiving sleeve of the lipstick mechanism to engage within the housing around the cup-shaped member. This space does not necessarily have to be annular over the entire circumference of the cup-shaped member. In fact, the cup-shaped member can be offset within the housing, allowing it to come closer to or even contact the inner wall of the housing. Thus, the crescent-shaped space is almost entirely annular. Advantageously, the button passes through this annular space. In other words, the annular space exists at the level where the button extends through a recess in the housing.

[0009] Advantageously, the recess defines an upper bottom opposite the lower opening, with the button abutting against the upper bottom and / or blocked in the recess near the upper bottom, for example, by a narrowed or equivalent profile. Thus, since the button is blocked in the recess, the replacement component is completely blocked in place within the housing. For example, the portion of the button extending between the two side edges of the recess may be wedged between the two side edges at the level of the partial narrowing of the recess, or the two side edges may form two corresponding bosses near the upper bottom, allowing the button to be retained by a removable snap-fit ​​engagement. The button may abut against the bottom of the recess and be locked in that position by a snap-fit ​​engagement clamping between the two side edges or beyond the two bosses. It can also be considered that the button can be blocked in the recess simply by clamping between the two side edges, advantageously near the bottom.

[0010] According to one embodiment, a slider can be disposed in the annular space, and the slider can be moved by sliding around the replacement component entity within the housing. The slider functions as a spacer or support by ensuring a complete annular space between the housing and the cup-shaped component. Therefore, the upper edge of the receiving sleeve can easily engage with the cup-shaped component within the housing in this well-formed annular space. The upper edge of the receiving sleeve then contacts the slider. Additional pushing of the upper edge of the receiving sleeve on the slider causes the slider to slide around the cup-shaped component without pressing contact, and then around the lipstick stick without contacting anything, so as not to smudge it during operation. In the final position, the slider is positioned at the bottom of the housing.

[0011] According to another embodiment, the cup-shaped member may form an elastic sheet that blocks access to the annular space. Under stress, the elastic sheet retracts radially inward to release access to the annular space. Preferably, the cup-shaped member is therefore made of a plastic material. It is the upper edge of the receiving sleeve that applies the necessary stress to the elastic sheet, thereby enabling access to the subsequent annular space. The elastic sheet performs three functions: holding the cup-shaped member within the housing, centering the cup-shaped member within the housing to ensure the annular space, and blocking the annular space and the housing. According to another embodiment, the cup-shaped member may form an elastic pin that, together with the elastic sheet, holds the cup-shaped member at the center of the housing. In a variation, the cup-shaped member may form an elastic sheet with an axially offset boss that contacts the housing, thereby holding the cup-shaped member at the center of the housing.

[0012] Alternatively, according to another embodiment, the housing may internally define a lower portion with an increased diameter and an upper portion with a decreased diameter, an annular space defined between the cup-shaped member and the lower portion with the increased diameter, the button passing through the annular space, and the cup-shaped member extending into the interior of the upper portion with the decreased diameter. Therefore, the upper edge of the receiving sleeve can penetrate the lower portion with the increased diameter until it abuts against the beginning of the upper portion with the decreased diameter. However, this is sufficient to engage the button within the longitudinal window of the receiving sleeve.

[0013] According to another aspect of the invention, the cup-shaped member may form a resilient blocking strip that protrudes radially outward in the resting state. A button is integral with the resilient blocking strip, and pressing the button causes the resilient blocking strip to move radially inward elastically. Once the replacement component is transferred into the receiving sleeve of the lipstick mechanism, the strip presses against the housing to hold the replacement component in place. To move the replacement component, the user must press the button to deform the strip inward before pushing the button up or down in the longitudinal window. The strip may be formed in a cup-shaped member made of metal or plastic.

[0014] According to one embodiment, the cup-shaped member can be pushed against the housing by a resilient retaining strip to define a crescent-shaped annular space. The cup-shaped member forms an access profile separate from the housing, which is advantageously arranged radially opposite to the resilient retaining strip. This access profile can also be defined as an insertion bevel, chamfer, or insertion space: it allows the upper edge of the receiving sleeve to navigate a channel between the housing and the cup-shaped member. Without this access profile, the upper edge of the receiving sleeve would actually abut against the bottom of the cup-shaped member, and insertion of the sleeve around the cup-shaped member would be impossible. Due to this feature, the upper edge of the receiving sleeve can engage between the housing and the cup-shaped member and push the cup-shaped member against the resilient retaining strip, navigating the path by completing the annular space. This access profile is particularly advantageous when the cup-shaped member is made of plastic material. In fact, the cup-shaped member can be held in the container by allowing the resilient retaining strip to rest, i.e., without stress. The strip simply pushes the cup-shaped member against the housing without actually pressing it. By slightly deforming the strip from its resting position, the access profile allows the cup-shaped member to be moved into the recess. In this case, assuming that the resting strap does not help to keep the cup-shaped part in the housing, it is advantageous to keep the button in the recess by the removable clamp or snap-fit ​​as described above.

[0015] Conversely, one could also consider a resilient retaining strip that is elastically pressed against the inner edge of the recess. Therefore, the cup-shaped component would be made of metal. In addition to the button resting against the bottom of the recess, the strip could even rest against the inner contour of the housing.

[0016] More generally, the housing may include at least one adjacent internal contour against which a cup-shaped member abuts to restrict insertion of a replacement element into the housing, the adjacent internal contour being advantageously integrally formed by the housing in the form of a cut or groove.

[0017] The invention also defines an assembly including a lipstick mechanism and at least one lipstick refill as described above. The lipstick mechanism includes a receiving sleeve adapted to receive a refill body of the lipstick refill. The receiving sleeve forms a longitudinal window defining a lower bottom opposite an upper opening. As a recess aligns with the longitudinal window, a button of the recess is slid into the longitudinal window through the upper opening of the longitudinal window and transferred, moving the refill body of the housing into the receiving sleeve, and the lipstick refill returns to the receiving sleeve. Advantageously, the receiving sleeve penetrates into the housing around the refill body, and the button engages in the longitudinal window through the upper opening.

[0018] Naturally, the movement of the button from the recess to the window can only be accomplished through the alignment of the recess and the window, which is easy for the user to do because the recess is very visible, just like the window. Furthermore, the recess opens downwards, while the window opens upwards.

[0019] Engagement of the button in the longitudinal window preferably occurs during the insertion of the receiving sleeve around the cup-shaped member into the housing: the button remains in the proper position within the recess, for example, against its bottom. In this case, the sleeve can sink until the replacement part has reached its initial position in the receiving sleeve. In a variant, the sleeve can sink into the housing until the replacement part has reached a mid-position in the receiving sleeve. Therefore, the user must manipulate the button to bring it to the initial position in the receiving sleeve. However, it is not excluded that engagement of the button in the longitudinal window is caused by the user operating the button, and the user subsequently brings it to the initial position in the receiving sleeve.

[0020] The scope of this invention also relates to including the cup-shaped component and the lipstick stick in a replacement body, unlike document US2770358, which only includes a pouched lipstick stick. The combination of a longitudinal groove with holding, blocking, and positioning functions with a button mounted or not mounted on the strip is particularly advantageous. An annular space, even if it can be crescent-shaped, is another particularly advantageous feature. Separate protection independent of the groove and the button can be sought. A housing containing the cup-shaped component (and the lipstick stick) and a space between the housing and the cup-shaped component for engaging a receiving sleeve constitute a separate inventive concept. Similarly, separate protection independent of the groove and the button can be used for a lipstick mechanism, the receiving sleeve of which has a longitudinal window opening at its upper end and forming a bottom at its lower end.

[0039] The lipstick replacement part of the present invention is used to replace the lipstick stick of a lipstick mechanism having the following characteristics. The lipstick mechanism M of the present invention is simpler than driving the lipstick stick axially up and down in the sleeve by rotating an actuating ring; the axial up and down of the lipstick stick B is achieved by directly acting on an axial translation button, which is integrated with a cup-shaped member in which the lipstick stick R is mounted.

[0040] More specifically, such as Figure 1a and 1b As shown, the lipstick mechanism M of the present invention includes a generally cylindrical receiving sleeve C. The sleeve C includes a longitudinal window C1 that extends vertically over a major portion of the height of the sleeve C. The window C1 is defined between two main parallel vertical side edges C2. The window C1 includes a lower bottom C3 and an upper opening C4. Optionally, a narrowing portion C5 may be provided near the upper opening C4: the two side edges C2 simply form two small bosses oriented toward each other to create a partial narrowing of the window C1. Below the lower bottom C3, the sleeve C may form a protruding annular ridge C6. The sleeve C may be provided with a housing cap C7 that engages around the lower end of the sleeve. The housing cap C7 is preferably snap-fit ​​or definitively forced in place. The housing cap C7 may extend until it contacts the protruding annular ridge C6. Although not shown, the two vertical side edges C2 may form a blocking profile, for example, in the form of teeth at the level of the window C1, or a notch formed along the window C1 at the level of the inner wall of the sleeve C.

[0041] The lipstick mechanism M of the present invention also includes a sheath F, which is closed at its upper end F1 and is detachably engaged around a sleeve C. The sheath F can be held in place on the sleeve C by a small raised profile. The sheath F can contact a protruding annular ridge C6. It is noteworthy that the lower edge of the sheath includes a notch F2, which, when the sheath F is in place on the sleeve C, can be aligned with a window C1, thereby making the lower bottom C3 visible.

[0042] The lipstick mechanism M of the present invention also includes replacement parts 1, 2, and 3 that are slidably and detachably mounted in the receiving sleeve C. Each replacement part includes a cup-shaped component and a lipstick stick B mounted within the cup-shaped component. The lipstick stick B may have a conventional shape, primarily cylindrical, with a sloping and rounded upper end. The lower end of the lipstick stick B is disposed within the cup-shaped component. As shown below, the cup-shaped component may have different embodiments G1, G2, and G3. Figure 1aThe first replacement component 1 and its cup-shaped member G1 are shown in the diagram, which will be described in more detail below. However, all replacement components 1, 2, and 3 share common features: particularly the lipstick stick B, and side buttons P1, P3, and P4 projecting radially outward at the level of the cup-shaped members G1, G2, and G3, for example, around the peripheral wall of the lipstick stick B. When the replacement component 1 is in the appropriate position within the sleeve C, the cup-shaped member G1 is located within the sleeve C, and the side button P1 is accessible through the longitudinal window C1 and operable from outside the sleeve C. Therefore, the user can raise and lower the lipstick stick B both outside and inside the sleeve C by moving the button P1 axially along the window C1. In the low position, the button rests against the lower bottom C3 of the window C1, and in the high position, the button P1 is stopped by the narrowing portion C5. However, the button P1 can be moved beyond the narrowing portion C5 by applying slight force. The button is therefore positioned at the level of the upper opening C4, and the replacement part body R can thus be removed from the sleeve C.

[0043] According to the present invention, the replacement parts 1, 2, 3 are combined with the housings E1, E2, E3 to form complete parts of the lipstick replacement parts R1, R2, R3, which are detachably accommodated in the housings E1, E2, E3. The lipstick stick B can be substantially the same in all embodiments and does not constitute a key element of the invention; the key elements are concentrated at the level of the cup-shaped members G1, G2, G3 and the housings E1, E2, E3. Before describing the various embodiments in detail, it is important to note that the lipstick replacement parts R1, R2, R3, R4 of the present invention are integral not only with the lipstick stick B but also with the cup-shaped members G1, G2, G3, which are used to detachably hold the replacement parts 1, 2, 3 in E1, E2, E3 and enable the replacement parts to be transferred to the receiving kit C of the lipstick mechanism M.

[0044] Reference Figure 2a , Figure 2b , Figure 2c , Figure 3a and Figure 3b The first embodiment of the present invention, which refills the lipstick with material R1, will now be described.

[0045] The replacement component R1 first includes a replacement component body 1, which is composed of a lipstick stick B disposed in a cup-shaped component G1, which is associated with a housing E1 that accommodates the replacement component body 1 and detachably holds it in place.

[0046] Lipstick stick B is presented in the form of a short stick of thick cosmetic. Conventionally, lipstick stick B may have a generally oval upper end cut by a sloping flat surface. Its lower end is received within a cup-shaped member G1, which includes a generally cylindrical sidewall G11 and an optional bottom G12. The cup-shaped member G1 also includes a resilient blocking strip L1 disposed in a cutout G13 formed in the sidewall G11. This strip L1 is sloping outwards so as to protrude relative to the sidewall G11. In this embodiment, the strip L1 extends upwards and outwards. In a variation, the strip may also extend downwards and outwards. In the resting state, the blocking strip L1 is sloping outwards, but it can also be closed in the cutout G13 by elastic deformation. This resilient blocking strip L1 supports a button P1, which itself also protrudes radially outwards from the outer surface of the strip L1. Therefore, by radially pressing the button P1, the strip L1 is deformable so that it returns to the cutout G13. The button P1 is also used to move the replacement component 1 translationally within the sleeve C of the aforementioned lipstick mechanism M. The lipstick stick B can be mechanically inserted into the cup-shaped component G1. In a variant, the lipstick stick B can be directly molded or cast into the cup-shaped component G1.

[0047] The housing E1 defines an internal receiving space to simultaneously accommodate the replacement component 1. The housing E1 includes an upper portion E11 with a decreasing diameter and a lower portion E13 with an increasing diameter. These two portions E11 and E13 are connected by a shoulder E14. The upper end E12 of the housing E1 is closed, while its lower end is open. Notably, the lower portion E13 has a longitudinal groove E15 that extends over its entire height or a portion thereof. This longitudinal groove E15 is defined between two parallel sides E16. The groove E16 includes an upper bottom E17 located near the shoulder E14 in this case, and a lower opening E18. Therefore, an element can be introduced into the groove E16 through its lower opening E18 and slid until it abuts against its upper bottom E17. Optionally, a narrowing portion E19 may be provided near the bottom E17 of the groove E15: the two sides E15 may form two bosses facing each other to create a local narrowing of the groove E16 near the upper bottom E17.

[0048] According to the present invention, the replacement component 1 is inserted into the housing E1 through the opening in the lower portion E13 of the housing E1, so that the button P1 passes through the groove E16. When the button P1 abuts against the upper bottom E17, it reaches the final installation position. Figure 2b , Figure 2c It can be noted that button P1 protrudes radially outward to the outside of recess E15. Therefore, it is directly accessible to the user. The strip L1 is entirely housed within the housing E1. It can be in a resting state or slightly compressed, pressing against or not pressing against the inner wall of the lower portion E13. In the final installation position, as... Figure 2cAs shown, the free upper end of strip L1 can even abut against shoulder E14. It can be noted that the upper edge of cup-shaped member G1 engages within the upper portion E11 of the reduced portion. This allows cup-shaped member G11 to be centered within the lower portion E13, thereby defining a generally cylindrical annular space S1 between housing E1 and the peripheral wall G11 of cup-shaped member G1. This annular space S1 is directly accessible from the open lower end of housing E1 surrounding the bottom G12 of cup-shaped member G1.

[0049] The final installation position of the filler body 1 within the housing E1 is ensured by the button P1 abutting against the upper bottom E17 of the recess E16. Locking of the replacement body 1 in its final installation position within the housing E1 can be ensured by: the button P1 snapping onto the outside of the narrowing portion E19 of the recess E15; the band L1 elastically pressing against the lower wall of the lower portion E13; or the upper end of the side wall G11 of the cup-shaped member G1 engaging frictionally within the upper portion E11. Combinations of these different retention mechanisms are also possible.

[0050] The cup-shaped member G1 and the housing E1 can be made of any suitable material. However, implementations using metal, particularly aluminum or steel, are preferred. When the cup-shaped member is made of plastic, the button P1 can be integrally formed with the strip and sidewall G11. When made of metal, the button P1 can return to the strip L1 integrally formed with the sidewall G11. Without departing from the scope of the invention, it is conceivable that the inner wall of the housing E1 is segmented, while its outer wall is not segmented. In particular, this can be made of plastic.

[0051] Now, refer to Figure 3a and Figure 3b This explains how the replacement component entity 1 of the replacement component R1 is transferred from the housing E1 to the sleeve C of the lipstick mechanism. Figure 3a As can be seen, the upper end of the sleeve C is engaged in the annular space S1 defined between the housing E1 and the cup-shaped member G1. As described above, this annular space S1 pre-exists in the replacement member R1, thus allowing the upper end of the sleeve C to be easily introduced into the housing E1 around the cup-shaped member G1. In other words, this annular space constitutes a device for engaging or inserting the sleeve C into the replacement member R1. Figure 3aIn this configuration, the upper edge of sleeve C is substantially at the level of the bottom of strip L1. It is understood that deeper insertion of sleeve C into housing E1 will cause sleeve C to press elastic band L1 inward into cutout G13. Thus, before window C1 is aligned with recess E15, sleeve C will be able to continue inserting into housing E1 until its upper edge abuts button P1. Otherwise, if pre-aligned, sleeve C will continue inserting into housing E1 until it abuts shoulder E14, where button P1 is introduced into window C1. Advantageously, button P1 is thus engaged in window F below narrowing C5. Replacement body 1 is thus in contact with sleeve C. The user can then press button P1 within sleeve C to drive replacement body 1 by sliding it into window C1 until it abuts its lower bottom C3. The user can then remove housing E1. In a variant, housing E1 can be removed once button P1 is inserted into window C1. Then, the user will slide the replacement body 1 inside the sleeve C by pressing the button P1 in window C1 until it touches its bottom C3.

[0052] Therefore, the longitudinal groove E15 allows the replacement part 1 to be positioned within the housing E1. The button P1 preferably abuts against the upper bottom E17 of the groove E15. In a variation, the button P1 may be wedged between the two side edges E16 near the upper bottom E17. Even a slight snap-fit ​​near the bottom E17 is conceivable to prevent the button P1 from being blocked within the groove E15. The visual alignment of the groove E15 with the window C1 allows the user to very easily and quickly transfer the replacement part 1 of the housing E1 into the sleeve C.

[0053] Figure 4a , Figure 4b and Figure 4c A second embodiment of the lipstick replacement part of the present invention is shown. The replacement part entity 1 is the same as in the first embodiment, including a lipstick stick B disposed in a cup-shaped member G1. The housing E2 is not segmented as in the first embodiment; instead, it is substantially or entirely cylindrical at the horizontal level of its inner wall, and preferably substantially or entirely cylindrical at the horizontal level of its outer wall as well. Like in the first embodiment, the housing E2 includes a longitudinal groove E25 defining an upper bottom E27 and a lower opening E28.

[0054] In this second embodiment, the replacement element R2 also includes a slider K, which may be presented as an unfinished small sleeve as it defines the channel K2. It is also noted that the lower edge of the slider K may form a retaining flange K1. The slider K is used for engagement around the cup-shaped element G1, where the channel K2 receives the band L1. The slider K may also be inserted into the housing. As in the first embodiment, when the replacement element body 1 is in place in the housing, the button P1 engages in the recess E25 until it abuts against its upper bottom E27. Alternatively, the side edges of the recess E25 may gradually move closer together near the upper bottom E27 to form a narrowing E29, so as to hold the button P1 in place or near the bottom E27 by clamping. Figure 4b As shown, the cup-shaped component G1 and the strip L1 can be observed through the groove E25. The sliding component K is positioned between the cup-shaped component G1 and the housing E2, as... Figure 4c As shown. The slider K and its flange K1 help to hold the replacement body 1 within the housing E2. The slider K also makes it possible to define an annular space S2 between the replacement body 1 and the housing E2.

[0055] Now refer to Figure 5a , Figure 5b and Figure 5c This describes how the replacement component 1 is transferred from the housing E2 to the sleeve C of the lipstick mechanism. Figure 5a In this configuration, the upper end of sleeve C is already engaged within the housing around cup-shaped member G1. This is possible because slider K can slide within housing E2 around replacement member entity 1, starting from cup-shaped member G1. It can be seen that the sliding movement of slider K has cleared the annular space between housing E2 and cup-shaped member G1, in which the upper end of sleeve C engages. The sinking of sleeve C within housing E2 can be achieved first by deforming band L1 inward, and then by engaging button P1 within window C1. The sinking of sleeve C within housing E2 will continue until slider K abuts against the top of housing E2, as... Figure 5b As shown. Therefore, button P1 has moved more than half the height of window C1 of sleeve C. Therefore, the user can press button 1, causing it to sink and drive until it contacts the bottom C3 of window C1. Therefore, housing E2 and its restricted slider K can be removed.

[0056] Similar to the first embodiment, an annular space is formed to accommodate the sleeve C, and the button P1 is engaged in the sleeve window C1. Although in both embodiments the button A1 does not contact the bottom C3, a variation of the sleeve C without the flange C6 can be considered, so that the button P1, abutting the bottom E17 of its groove E15, can reach the bottom C3 of the sleeve.

[0057] The housing E2 with the slider K can be made of any suitable material, but is preferably made of plastic.

[0058] Figure 6a , Figure 6b , Figure 6c and Figure 6d A third embodiment of the lipstick replacement part of the present invention is shown. The replacement part entity 2 differs from the previous embodiments in the level of its cup-shaped member G2, which is in... Figure 6a This is more evident in the middle. The cup-shaped member G2 is preferably made of a plastic material, such as aliphatic polyketone. The cup-shaped member G2 includes sidewalls G21, but no bottom. The sidewalls G21 form a button P2, which is not meant to be depressed, but rather to be simply gripped for axial movement. The sidewalls G21 also include two resilient pins G23, which will make frictional contact with the inside of the sleeve C of the lipstick mechanism. It can also be noted that the lower end of the cup-shaped member G2 forms resilient pieces or segments G22 separated by grooves. These resilient pieces or segments G22 protrude outward when at rest. However, these resilient pieces or segments G22 can move radially inward under stress.

[0059] The cup-shaped component G2 is also adapted to accommodate the lipstick stick B to jointly form the replacement component entity 2. The replacement component entity 2 is... Figure 6b The designation is indicated by a longitudinal groove E35 formed within the housing E3, ending at the bottom E37. The groove E35 may be substantially similar to or identical to the groove in the aforementioned embodiment. In this case, the housing E3 is characterized by the addition of a stop E39, which allows for removable blocking of the bottom of the housing E3. It is noted that the button P2 engages in the groove E35 until it abuts against its bottom E37. On the other hand, the elastic sheet G22 and the elastic pin G23 make slight contact with the interior of the housing E3. Therefore, these elastic sheets G22 and elastic pins G23 help to axially hold the replacement body 2 within the housing E3. These elastic sheets G22 and elastic pins G23 also define an annular space S3 between the replacement body 2 and the housing E3 by centering the cup-shaped member G2 within the housing E3. Thus, it can be said that the elastic sheet G22 and elastic pin G23 form an axial centering or guiding device.

[0060] exist Figure 6b In the image, it can be seen that the upper end of sleeve C is already engaged within the housing E3. Understandably, the upper edge of sleeve C will contact the elastic tabs G22. Due to their flexibility, these elastic tabs will be pressed inward by the upper edge of sleeve C, as... Figure 6c As shown. Therefore, the engagement of sleeve C within housing E3 can be continued by engaging button P2 in window C1 of sleeve C. The engagement ends when the lower edge of housing E3 abuts against flange C6 of sleeve C, which is shown. Figure 6cAs shown in the diagram. Subsequently, the user can remove the housing E3 and press button P2 until it abuts against the bottom C3 of the window C1 of the sleeve C.

[0061] It must be noted that the movement of the cup-shaped member G2 within the sleeve C is accomplished solely through friction between the pin G23 and the elastic plate G22. The button P2 is not intended to retract to release the movement of the cup-shaped member G21, as is the case in the two first embodiments with the elastic stop bar L1.

[0062] exist Figure 6e A variation of the embodiment of cup-shaped member G2, designated G2', can be seen in the housing E3: cup-shaped member G2' can be used instead of cup-shaped member G2. Like cup-shaped member G2, cup-shaped member G2' can be made of aliphatic polyketone. Cup-shaped member G2' includes sidewalls G21', which may not have a bottom. Sidewalls G21' form a button P2, which is not intended to be depressed but rather to be simply grasped for axial movement. Sidewalls G21' also include elastic plates G22' and G23', which are alternately arranged and separated by slots. Elastic plate G22' forms a boss G221, while elastic plate G23' forms a boss G231. These bosses G221 and G231 project radially outward. Boss G221 is axially offset relative to boss G231. When cup-shaped member G2' is inserted into housing E3, plates G22' and G23' are radially inwardly pressed. They can also define an annular space S3 between the replacement body 2 and the housing E3 by centering the cup-shaped member G2' within the housing E3. Therefore, it can be said that the elastic plates G22' and G23' form axial centering or guiding devices.

[0063] exist Figure 7a , Figure 7b , Figure 7c and Figure 7d The image shows a fourth embodiment of the lipstick replacement component. This embodiment of the lipstick replacement component 3 includes a lipstick B and a cup-shaped component G3, which... Figure 7a This is more clearly visible in the image. The cup-shaped member G3 also includes a sidewall G31 forming a cutout G33, in which an elastic blocking strip L3 extends, and a button P3 is formed on the elastic blocking strip L3. Therefore, by radially pressing the button P3, the blocking strip L3 deforms and moves radially inward into the cutout G33. This embodiment can be considered a variation of the cup-shaped member G1. However, it can be noted that the blocking strip L3 extends downward, rather than upward as in the cup-shaped member G1. The cup-shaped member G3 also forms an access contour G32, which can be presented in the form of a bevel or a rounded edge. Its function will be given below.

[0064] The cup-shaped component G3 is preferably made of injection-molded plastic material, but it can also be made of metal. The cup-shaped component G3 contains the lipstick stick B to form the lipstick replacement component 3.

[0065] exist Figure 7b In the diagram, the replacement piece 3 can be seen positioned within the housing E3, which may be substantially similar to or identical to the third embodiment. The button P3 engages in the recess E35 up to its bottom, as in the previous embodiment. It can also be noted that the strip L3 does not deform: it is essentially in its resting state. It can also be seen that the replacement piece entity 3 is offset or eccentric to the right within the housing E3. In fact, the right edge of the cup-shaped piece G3 contacts the housing E3, while the left edge forming the strip L3 moves away from the housing E3. Therefore, a crescent-shaped, essentially annular space S4 is defined between the cup-shaped piece G3 and the housing E3. This annular space S4 also defines the lipstick stick B. The access contour G32 is located at the level where the cup-shaped piece G3 contacts the housing E3. Figure 7b In this configuration, the upper edge of sleeve C is already engaged within housing E3. Therefore, it is readily understood that the access profile G32 facilitates the engagement of sleeve C around the cup-shaped member by shifting sleeve C to the left within housing E3. Alternatively, the access profile G32 allows the upper edge of sleeve C to navigate between cup-shaped member G3 and housing E3 by shifting the path between cup-shaped member G3 and housing E3 to the left, which has the effect of deforming band L3. Therefore, sleeve C can continue to be inserted into housing E3 by further deforming band L3, as... Figure 7c As shown. Therefore, the engagement of the sleeve within the housing E3 allows the annular space S4 to change from a crescent shape to a complete annular shape. All that remains is for the user to move button P3 to the bottom C3 of window C1. Housing E3 can be removed before or after this operation.

[0066] It is important to note that the elastic strip L3 will not be subjected to stress within the housing E3, thus eliminating the risk of creep deformation. The button P3 can be held in the groove E35 by clamping between these sides or by a slight snap-fit, as described above. Axial displacement of the replacement body 3 within the housing E3 will not be obstructed, as the sleeve C can still be inserted around the replacement body 3 due to the access contour G32, preventing the sleeve C from directly abutting against the cup-shaped part G3.

[0067] The four embodiments described so far highlight two important features that can be implemented independently: a recess in the housing that accommodates the button and an annular space between the replacement body and the housing that allows the sleeve to engage around the replacement body to accommodate it. Another important feature of the invention is that the button engages in a window in the sleeve C, and also engages at the bottom of the recess in the housing. Similarly, in all embodiments, the button passes through the annular space. The button can simply abut against the bottom of the recess and / or be blocked at or near the bottom by any suitable reversible blocking device, such as a narrowing of the recess, a thickening of the recess edge, a strip pressing against the inner wall of the housing, friction between the cup-shaped member and the housing, etc. It can be seen that the cup-shaped member can be made of metal or plastic, with or without an elastic blocking strip.

[0068] As a result of this invention, lipstick replacement parts are available, integrating a replacement part entity consisting of a cup-shaped component and a lipstick stick together. This replacement part entity can be transferred from the housing into the sleeve of a sliding lipstick mechanism without the risk of contact with the lipstick stick. For example, a box comprising lipstick mechanisms associated with several identical or different lipstick replacement parts can be considered.
