Description

lipstick refill

The present invention relates to a lipstick refill comprising a cup and a stick of lipstick received in the cup, so as to form together a refill entity. The recharge also includes a case in which the recharge entity is held in position, but in a removable manner. The recharging entity is intended to be transferred from the case into a lipstick mechanism which comprises a receiving sleeve adapted to receive the recharging entity in a sliding manner. This reception sleeve has the particularity of forming a longitudinal window in which the pusher of the cup is manually movable, in order to bring the grapes out or into the reception sleeve.

In the prior art, document US2770358 is known which describes a lipstick mechanism of this type, with a receiving sleeve forming a longitudinal window in which the pusher of a cup is manually movable. The raisin, which is packaged in a sachet, is placed in the cup of the lipstick mechanism by the user. It may be noted 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 notches and the bucket pusher comprises two small tabs, which can be elastically brought together between the thumb and the index finger, so as to be able to unlock and move the bucket in the shirt .

The disadvantage with this sachet refill is that it is difficult to handle it without the fingers coming into contact with the grapes, once the sachet is opened. In addition, it is not easy to insert the grapes into the bucket. The reloading operation is therefore both messy and complicated.

In the prior art, document FR1124179A is also known, which describes a refill comprising a cup provided with a lug which is engaged in a vertical slot formed in a protective case. This pin is not intended to be manipulated by the user, but simply to be engaged in two grooves (axial and spiral) of a lipstick mechanism. This document specifies that the case (cover) is removed before engaging the bucket on the mechanism in order to insert the lug into the grooves. Contact with reason is thus inevitable.

The object of the invention is to overcome the drawbacks of the prior art by proposing a lipstick refill which avoids any contact with the stick and whose installation in the lipstick mechanism is easy and guaranteed.

To do this, the present invention proposes a lipstick refill comprising a cup, a lipstick stick received in the cup, so as to form together a refill entity and a case in which the refill entity is received in a fixed and removable manner, the case forming a longitudinal notch, characterized in that the cup is provided with a pusher which projects radially on the outside of the case passing through this longitudinal notch.

The longitudinal indentation fulfills several functions: the first being to block the charging unit in the case. Indeed, the engagement of the pusher in the indentation considerably reduces its degree of freedom in the case. The second function of the notch is to be able to easily visualize the positioning of the pusher to facilitate its transfer into the longitudinal window of the lipstick mechanism receiving sleeve. The user can very simply align the longitudinal notch on the longitudinal window to prepare the transfer of the charging entity. Then, the user grasps the pusher to move it from the longitudinal indentation in the lipstick mechanism. The pusher therefore constitutes the organ dedicated to the transfer of the refill entity, of the refill in the lipstick mechanism.

According to a very advantageous characteristic of the invention, a substantially cylindrical annular space can be defined between the charging entity and the case. This annular space allows the receiving sleeve of the lipstick mechanism to engage inside the case around the bucket. This space is not necessarily annular over the entire periphery of the bucket. In effect, the cup can be off-center in the case, so that it can approach or even come into contact with the internal wall of the case. The fact remains that space, then in the shape of a crescent moon, is almost entirely annular. Advantageously, the annular space is crossed by the pusher. In other words, the annular space is present at the level where the pusher extends through the indentation of the case.

Advantageously, the notch defines an upper bottom opposite a lower opening, the pusher being in abutment against the upper bottom and/or blocked in the notch close to the upper bottom, for example by a constriction or an equivalent profile. Thus, the charging unit is perfectly locked in position in the case, thanks to its pusher locked in the indentation. One can for example provide that the part of the pusher which extends between the two lateral edges of the indentation is wedged between the two lateral edges at the level of a local narrowing of the indentation or that the two lateral edges form two respective bosses close to the upper bottom which make it possible to maintain the pusher by removable snap-fastening. The plunger can be in abutment against the bottom of the notch and locked in this position by wedging between the two side edges or snapping in place beyond two bosses. It is also possible to envisage blocking the pusher in the indentation only by wedging between the two lateral edges, advantageously close to the bottom.

According to one embodiment, a slider can be arranged in this annular space, this slider being movable by sliding in the case around the charging entity. This slide fulfills a function of spacer or spacer by guaranteeing a perfectly annular space between the case and the bucket. The upper edge of the receiving sleeve can thus be easily engaged in the case around the bucket in this well-formed annular space. Then, the upper edge of the receiving sleeve comes into contact with the slider. An additional push of the upper edge of the receiving sleeve on the slider will cause the slider to move around the cup, but without pressed contact, then around the grapes, without contact at all, so as not to mark it during handling. At the end of the race, the slider is positioned at the bottom of the case.

According to another embodiment, the cup can form elastic tabs which obstruct access to this annular space, the elastic tabs retracting radially inwards under stress to free access to the annular space. Preferably, the cup is then made of plastic. It is the upper edge of the receiving sleeve which will exert the necessary stress on the elastic tabs in order to then be able to access the subsequent annular space. The elastic tabs fulfill a triple function: holding the cup in the case, centering the cup in the case to guarantee an annular space and sealing off this annular space and the case. According to one embodiment, the cup can form elastic pins which, together with the elastic tabs, allow the cup to be held centrally in the case. As a variant, the cup can form elastic tabs forming bosses which are axially offset and which come into contact with the case, thus maintaining the cup in a centered manner in the case.

According to yet another embodiment, the case may internally define a lower section of increased diameter and an upper section of reduced diameter, the annular space being defined between the cup and the lower section of increased diameter, the annular space being traversed by the pusher, the cup extending to the interior of the upper section of reduced diameter. Thus, the upper edge of the receiving sleeve can penetrate into the lower section of increased diameter until it comes into abutment against the start of the upper section of reduced diameter. However, this is sufficient to engage the pusher in the longitudinal window of the receiving sleeve.

According to another aspect of the invention, the bucket can form an elastic locking tongue which projects radially outwards in the rest state, the pusher being integral with this elastic locking tongue, pressing on the pusher allowing to elastically move the elastic locking tab radially inwards. After the charging entity is transferred to the lipstick mechanism receiving folder, this tab will press against the case to lock the charging unit in place. To move the charging entity, the user will have to press the pusher to deform the tongue inwards before pressing the pusher upwards or downwards in the longitudinal window. This tab can be formed in a metal or plastic bucket.

According to one embodiment, the cup can be pushed by the elastic blocking tab against the case so as to define an annular space in the shape of a crescent moon, the cup forming an access profile which is separate from the case , this access profile being advantageously arranged diametrically opposite the elastic locking tab. This access profile can also be described as an insertion ramp, chamfer or insertion space: it allows the upper edge of the receiving sleeve to make its way between the case and the cup. Without this access profile, the upper edge of the receiving liner would bump squarely against the bottom of the bucket and the insertion of the liner around the bucket would not be possible. Thanks to this feature, the upper edge of the receiving sleeve can engage between the case and the cup and push the cup against the elastic blocking tongue to clear a path by completing the annular space. This access profile is particularly advantageous when the bucket is made of plastic. Indeed, the cup can thus be maintained in the case by leaving the elastic locking tongue at rest, that is to say without constraint. The tab simply pushes the cup towards the case without any real support. The access profile allows the bucket to be moved towards the indentation by slightly deforming the tab from its resting state. It is in this case advantageous to block the pusher in the indentation by means of a wedging or a removable snap, as defined above, given that the tab at rest does not participate in maintaining the bucket in the 'case.

Conversely, it is also possible for the elastic locking tab to be elastically constrained against the inner side edges of the notch. The cup is then rather made of metal. The tab can even come into abutment against an internal profile of the case, in addition to the pusher in abutment at the bottom of the indentation.

More generally, the case may comprise at least one inner abutment profile against which the cup abuts to limit the insertion of the refill entity into the case, this inner abutment profile being advantageously formed in one piece by the case in the form of a cutout or a groove.

The invention also defines an assembly comprising a lipstick mechanism and at least one lipstick refill as defined above, the lipstick mechanism comprising a receiving sleeve adapted to receive the the lipstick refill, this receiving sleeve forming a longitudinal window defining a lower bottom opposite an upper opening, the lipstick refill being attached to the receiving sleeve with the indentation aligned with the longitudinal window to transfer by sliding the pusher of the indentation in the longitudinal window through its upper opening, thus moving the charging entity from the case into the receiving jacket. Advantageously, the receiving sleeve enters the case around the charging entity, the pusher engaging in the longitudinal window through its upper opening.

Of course, the transfer of the pusher from the indentation to the window can only be done with the alignment of the indentation and the window, which the user can easily achieve, since the indentation is very visible, while like the window. In addition, the indentation is open downwards and the window upwards.

The engagement of the pusher in the longitudinal window preferably occurs during the insertion of the receiving sleeve inside the case around the bucket: the pusher remaining in place in the indentation, for example in abutment against its bottom. The shirt can be pushed into the holster until the charging entity has gained its starting position in the receiving shirt. Alternatively, the shirt can be pushed into the case until the charging entity has gained an intermediate position in the shirt reception. The user will then have to manipulate the pusher to bring it to the starting position in the receiving sleeve. However, it is not excluded that the engagement of the pusher in the longitudinal window results from manipulation of the pusher by the user, who will then bring it to the starting position in the receiving sleeve.

The spirit of the invention is also based on the fact of including the cup in the refill entity with the grapes, unlike the document US2770358, in which the only grape is bagged. The longitudinal indentation with its holding, blocking and marking functions, in association with the pusher, mounted on a tongue or not, is particularly advantageous. The annular space, although it may be crescent-shaped, is another particularly advantageous feature. A separate protection, independent of the indentation and the pusher, could be sought. A case containing a scoop (plus a grape) with a space between the case and the scoop for engagement of the receiving jacket is an independent inventive concept. Similarly, a separate protection, independent of the notch and the pusher, could be sought for a lipstick mechanism whose longitudinal window of the receiving sleeve is open at its upper end and forms a bottom at its lower end.

The invention will now be more fully described with reference to the attached drawings, giving, by way of non-limiting examples, several embodiments of the invention.

The lipstick refill of the invention is intended for replacing the stick of a lipstick mechanism which has the following characteristics. Rather than driving the axial ascent and descent of the grape in a sleeve by rotation of an actuating ring rotary, the lipstick M mechanism of the invention is simpler, since the axial raising and lowering of the grape B is done by acting directly on an axial translating pusher which is integral with a bucket in which the grape B is mounted .

More specifically, as can be seen in Figures 1a and 1b, the lipstick mechanism M of the invention comprises a receiving sleeve C of substantially cylindrical shape. This sleeve C comprises a longitudinal window C1 which extends vertically over most of the height of the sleeve C. This window C1 is defined between two vertical side edges C2 which are generally parallel. The window C1 comprises a lower bottom C3 and an upper opening C4. Optionally, a narrowing C5 can be provided near the upper opening C4: the two side edges C2 simply form two small bosses oriented towards each other so as to create a localized narrowing of the window C1. Below the lower bottom C3, the sleeve C can form a projecting annular rib C6. The sleeve C can be provided with a trim cap C7 which is engaged around the lower end of the sleeve. The C7 trim cap is preferably snapped or force-fitted permanently. This covering base C7 can extend as far as in contact with the projecting annular rib C6. Although not shown, the two vertical side edges C2 can form blocking profiles, for example in the form of teeth at the level of the window C1 or even notches at the level of the internal wall of the sleeve C along the window C1.

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 profiles in relief. The sheath F can come into contact with the projecting annular rib C6. One can notice that the lower edge of the sheath includes a notch F2, which can be aligned with the window C1, so that it leaves the lower bottom C3 visible, when the sheath F is in place on the sleeve C. The lipstick mechanism M of the invention further comprises a charging entity 1, 2, 3 which is slidably and removably mounted in the receiving sleeve C. This charging entity comprises a cup and a grape B mounted in the bucket. Grapes B can have a classic shape, mostly cylindrical with a beveled and rounded top end. The lower end of grape B is embedded in the bucket. As will be seen below, the bucket can have different embodiments G1, G2, G3. In FIG. 1a, it is the first refill entity 1 with its bucket G1 which is shown: it will be described in more detail below. All the charging entities 1, 2, 3 however have common characteristics, in particular the grape B, but also at the level of the cups G1, G2, G3, such as a peripheral wall which surrounds the grape B and a lateral pusher P1, P3, P3 which projects radially outwards. When the refill entity 1 is in place in the sleeve C, the cup G1 is located inside the sleeve C with the lateral pusher P1 which crosses the longitudinal window C1 so as to be accessible and manipulable from the outside of the sleeve C. Thus, a user can move grapes B up and down outside and inside the sleeve C by moving the pusher P1 axially along the window C1. In the low position, the pusher abuts against the lower bottom C3 of the window C1 and in the high position, the pusher P1 is stopped by the tightening C5. However, it is possible to move the pusher P1 beyond the tightening C5 by forcing a little. The pusher is then positioned at the level of the upper opening C4 and the charging entity R can then be extracted from the sleeve C.

According to the invention, the refill entity 1, 2, 3 is an integral part of a lipstick refill R1, R2, R3, R4 in association with a case E1, E2, E3 in which the refill entity is received detachably. The grape B can be substantially identical in all the embodiments and does not constitute a critical element of the invention, which is concentrated at the level of the cup G1, G2, G3 and the case E1, E2, E3. Before describing the various embodiments in detail, it may first be noted that the lipstick refill R1, R2, R3, R4 of the invention does not incorporate only the grape B, but also the cup G1, G2, G3, which will be used for the removable maintenance of the refill entity 1, 2, 3 in the case E1, E2, E3 and allow the transfer of the entity from refill to receiving jacket C of lipstick mechanism M.

With reference to Figures 2a, 2b, 2c, 3a and 3b, we will now describe the first embodiment for a lipstick refill R1 of the invention.

This refill R1 firstly comprises a refill entity 1, consisting of a grape B encased in a cup G1, which is associated with a case E1 in which the refill entity 1 is received and held in place in a removable manner. .

Raisin B is in the form of a stick of pasty cosmetic product. Quite conventionally, the stick B may have an upper end of substantially ogival shape cut by an inclined square face B1. 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 an elastic blocking tab L1 arranged in a cutout G13 formed in the side wall G11. This tongue L1 is inclined outwards so as to project relative to the side wall G11. In this embodiment, tab L1 extends upward and outward. Alternatively, the tab could also extend downward and outward. In the rest state, the locking tab L1 is inclined outwards, but it is possible to fold it into the cutout G13 by elastic deformation. This elastic locking tab L1 supports a pusher P1 which also projects radially outwards from the outer face of the tab L1. Thus, by pressing radially on the pusher P1, the tongue L1 can be deformed so as to bring it back into the cutout G13. This pusher P1 will also be used to move the refill entity 1 in a translational manner in the sleeve C of the lipstick mechanism M previously described. Raisin B can be inserted mechanically inside cup G1. As a variant, grape B can be molded or cast directly inside cup G1. The case E1 internally defines a reception space to house therein both the charging entity 1. 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 may be noted that the lower section E13 is formed with a longitudinal notch E15 which may extend over all or part of the height of the lower section E13. This longitudinal notch E15 is defined between two parallel side edges E16. The notch E16 comprises an upper bottom E17, here arranged close to the shoulder E14, as well as a lower opening E18. It is therefore possible to introduce an element into the notch E16 through its lower opening E18 and to make it slide until it comes into abutment against its upper bottom E17. Optionally, a narrowing E19 can be provided near the bottom E17 of the notch E15: the two side edges E15 can form two small bosses oriented towards each other so as to create a localized narrowing of the notch E16 at near the upper bottom E17.

According to the invention, the charging entity 1 is inserted inside the case E1 through the opening of its lower section E13, so that the pusher P1 passes through the notch E16. The final mounting position is reached when the pusher P1 comes into abutment against the upper bottom E17. It can be seen in Figures 2b, 2c that the pusher P1 protrudes radially outwards out of the notch E15. It is therefore directly accessible by a user. The tab L1 is arranged entirely inside the case E1. It can be in a state of rest or slightly under stress so as to press or not against the internal wall of the lower section E13. In the final mounting position, as shown in Figure 2c, the free upper end of the tongue L1 can even come into abutment against the shoulder E14. It may be noted that the upper edge of the cup G1 is engaged inside the upper section E11 of reduced section. This makes it possible to center the cup G11 inside the lower section E13 so as to define a substantially cylindrical annular space S1 between the case E1 and the peripheral wall G11 of the cup G1. This annular space 81 is directly accessible via the lower open end of the case E1 around the bottom G12 of the cup G1.

The final mounting position of the charging unit 1 inside the case E1 is guaranteed by the abutment of the pusher P1 against the upper bottom E17 of the notch E16. The blocking in the final mounting position of the charging entity 1 inside the case E1 can be ensured either by the pusher P1 snapped in beyond the tightening E19 of the notch E15, or by the elastic support of the tab L1 against the lower wall of the lower section E13, or by the frictional engagement of the upper end of the side wall G11 of the cup G1 inside the upper section E11. A combination of these different postures is also possible.

The G1 Cup and E1 Case can be made of any suitable material. However, a metal construction, in particular aluminum or steel, is preferred. The pusher P1 can be made in one piece with the tab and the side wall G11 when the cup is made of plastic. In metal, the pusher P1 can be attached to the tab L1 which is integral with the side wall G11. Without departing from the scope of the invention, one can imagine that the inner wall of the case E1 is stepped, but not its outer wall. This is in particular achievable in plastic material.

Reference will now be made to FIGS. 3a and 3b to explain how the refill entity 1 of the refill R1 is transferred from the case E1 into the sleeve C of the lipstick mechanism. In Figure 3a, we see that the upper end of the sleeve C is already engaged in the annular space S1 defined between the case E1 and the cup G1. As mentioned above, this annular space S1 is pre-existing in the refill R1 and thus allows the upper end of the sleeve C to be easily introduced into the case E1 around the cup G1. It can be said that this annular space constitutes a means of engagement or insertion of the sleeve C in the refill R1. In FIG. 3a, the upper edge of the sleeve C is located substantially at the level of the base of the tab L1. We understand that an insertion more depth of the liner C inside the case E1 will cause the liner C to force the elastic tongue L1 inwards in the cutout G13. The sleeve C will thus be able to continue its insertion into the case E1 until its upper edge abuts against the pusher P1, in the event that the window C1 is not yet aligned with the notch E15. Otherwise, when the alignment has been carried out beforehand, the sleeve C will continue its insertion into the case E1 until it comes into abutment with the shoulder E14, with the pusher P1 inserted inside the window C1. Advantageously, the pusher P1 is then already engaged in the window F below the tightening C5. It can be said that the charging entity 1 is then engaged in the sleeve C. The user can then enter the pusher P1 to drive the charging entity 1 inside the sleeve C by sliding in the window C1 until it comes into abutment with its lower bottom C3. The user can then remove the E1 case. As a variant, the case E1 can be removed as soon as the pusher P1 is inserted into the window C1. Then, the user will slide the charging entity 1 inside the jacket C by pressing the pusher P1 which he slides in the window C1 until it comes into abutment against its bottom C3.

The longitudinal notch E15 therefore makes it possible to fix the position of the charging entity 1 inside the case E1. The pusher P1 preferably comes into abutment against the upper bottom E17 of the notch E15. As a variant, the pusher P1 can be wedged between the two side edges E16 close to the upper bottom E17. One can even imagine a slight click close to the bottom E17, in order to block the pusher P1 inside the cutout 15. The visual alignment of the cutout E15 with the window C1 allows the user to transfer very easily and quickly charging unit 1 of case E1 into folder C.

Figures 4a, 4b and 4c show a second embodiment for a lipstick refill of the invention. The charging entity 1 is identical to that of the first embodiment, comprising a grape B encased in a cup G1. Case E2 is not stepped as in the first embodiment, but on the contrary substantially or perfectly cylindrical at its inner wall, and preferably also at its outer wall. The case E2 comprises a longitudinal notch E25 defining an upper bottom E27 and a lower opening E28, just as in the first embodiment.

In this second embodiment, the refill R2 further comprises a slider K which may be in the form of a small sleeve 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 retaining bead K1. This slider K is intended to be engaged around the bucket G1 with the passage K2 receiving the tongue L1. The K slider can also be inserted inside the case. Just as in the first embodiment, when the charging entity 1 is in place in the case, the pusher P1 is engaged in the notch E25 until it comes into abutment with its upper bottom E27. Optionally, the lateral edges of the notch E25 can gradually approach one another near the upper bottom E27 to create a tightening E29 in order to maintain the pusher P1 in position by wedging against or near the bottom E27. The cup G1 and the tongue L1 can be observed through the notch E25, as can be seen in figure 4d. The slider K is arranged between the bucket G1 and the case E2, as can be seen in Figure 4c. The slider K with its bead K1 can participate in maintaining the charging entity 1 inside the case E2. The slider K also makes it possible to define an annular space S2 between the charging entity 1 and the case E2.

Reference will now be made to FIGS. 5a, 5b and 5c to describe how the refill entity 1 is transferred from the case E2 into the sleeve C of a lipstick mechanism. In FIG. 5a, the upper end of the sleeve C is already engaged inside the case around the cup G1. This is possible because the slider K can move by sliding inside the case E2 around the charging entity 1, starting with its cup G1. It can be observed that the sliding movement of the slider K has cleared an annular space between the case E2 and the cup G1 in which the upper end of the sleeve C is engaged. The depression of the sleeve C inside I case E2 can continue first by deforming the tab L1 inwards, then by engaging the pusher P1 inside the window C1. The insertion of the sleeve C into the case E2 will continue until the slider K comes into abutment against the top of the case E2, as can be seen in FIG. 5b. The pusher P1 has then already covered more than half the height of the window C1 of the sleeve C. The user can then grab the pusher P1, push it down and drive it until it comes into contact with the bottom C3 of the window C1. Case E2 can then be removed with its captive slider K.

Just as in the first embodiment, an annular space is created to receive the sleeve C and to engage the pusher P1 in the window C1 of the sleeve. Although the pusher P1 does not come into contact with the bottom C3 in these two embodiments, a variant can be envisaged in which the sleeve C has no bead C6, thus allowing the pusher P1 abutting the bottom E17 of its indentation E15 to reach the bottom C3 of the shirt.

The case E2 with its slider K can be made of any suitable material, and preferably of plastic.

Figures 6a, 6b, 6c and 6d illustrate a third embodiment for a lipstick refill of the invention. The refill entity 2 differs from the previous embodiment at the level of its cup G2, which is more visible in FIG. 6a. This cup G2 is preferably made of plastic material, for example aliphatic polyketone. It includes a G21 sidewall, but lacks a bottom. The side wall G21 forms a pusher P2, which is not intended to be pressed, but simply to be grasped for axial movement. The side wall G21 also comprises two elastic pins G23 which will come into frictional contact inside the sleeve C of the lipstick mechanism. It can also be noted that the lower end of the cup G2 forms tabs or elastic segments G22 which are separated by slots. These elastic G22 tabs protrude outwards when at rest. They are, however, displaceable under stress radially inwards. The G2 bucket is also adapted to receive a grape B to together form the refill entity 2. The latter is shown in Figure 6b engaged inside a case E3 which forms a longitudinal notch E35 terminated by an upper bottom E37. The notch E35 may be substantially similar or identical to those of the previous embodiments. The E3 case is characterized here by the addition of an E39 plug which allows its bottom to be closed in a removable manner. It can be seen that the pusher P2 is engaged in the notch E35 until it comes into abutment against its bottom E37. On the other hand, the elastic tabs G22 and the elastic pins G23 come into slight contact with the inside of the case E3. These elastic lugs G22 and elastic pins G23 thus contribute to the axial retention of the charging entity 2 inside the case E3. They also make it possible to define an annular space S3 between the charging entity 2 and the case E3 by centering the cup G2 inside the case E3. It can thus be said that the elastic lugs G22 and the elastic pins G23 form means of centering or of axial guidance.

In Figure 6b, we can see the upper end of the sleeve C already engaged inside the case E3. It is understood that the upper edge of the liner C will come into contact with the elastic tabs G22. Due to their flexibility, these tabs will be constrained by the upper edge of the sleeve C inwards, as shown in Figure 6c. The engagement of the sleeve C inside the case E3 can thus continue by engaging the pusher P2 in the window C1 of the sleeve C. This engagement ends when the lower edge of the case E3 comes into abutment against the bead C6 of the shirt C, this is shown in Figure 6c. From then on, the user can remove the case E3 and push the pusher P2 until it comes into abutment against the bottom C3 of the window C1 of the sleeve C.

It should be noted that the displacement of the bucket G2 inside the liner C is done solely by friction at the level of the pins G23 and the elastic tabs G22. The pusher P2 is not intended to be pressed to release the displacement of the cup G21, as was the case in the first two embodiments with the elastic locking tongue L1. In FIG. 6e, one can see a variant embodiment of the cup G2, which is designated G2': this cup G2' can be used instead of the cup G2 in the case E3. Just like the G2 bucket, this G2' bucket can be made of aliphatic polyketone. It includes a G2T side wall, which can be bottomless. The side wall G2T forms a pusher P2, which is not intended to be pressed, but simply to be grasped for axial displacement. The side wall G2T also comprises elastic tabs G22' and G23' which are arranged alternately and separated by slots. The elastic tabs G22' form bosses G221 and the elastic tabs G23' form bosses G231. These bosses G221 and G231 project radially outwards. The G221 bosses are axially offset from the G231 bosses. The tabs G22' and G23' are constrained radially inwards, when the cup G2' is inserted into the case E3. They also make it possible to define an annular space S3 between the refill entity 2 and the case E3 by centering the cup G2' inside the case E3. It can thus be said that the elastic lugs G22' and G23' form centering or axial guiding means.

The fourth embodiment for a lipstick refill is shown in Figures 7a, 7b, 7c and 7d. The lipstick refill 3 of this embodiment comprises a grape B, as well as a cup G3, more visible in FIG. 7a. This cup G3 also comprises a side wall G31 forming a cutout G33 in which extends an elastic locking tab L3 on which a pusher P3 is formed. Thus, by radial pressing on the pusher P3, the tongue L3 is deformed and moves radially inwards in the cutout G33. This embodiment can be considered as a variant of the G1 bucket. However, one can notice that the tongue L3 extends downwards, and not upwards, as in the cup G1. The G3 bucket also forms a G32 access profile, which can be a chamfered or rounded edge. Its function will be given below. The G3 cup is preferably made by injection molding of plastic material, but it can also be made of metal. He receives a B grape to form a 3 lipstick refill.

In FIG. 7b, this refill 3 can be seen in place in a case E3, which can be substantially similar or identical to that of the third embodiment. The pusher P3 is engaged in the notch E35 up to the level of its bottom, just as in the previous embodiments. We can also notice that the tongue L3 is not deformed: it is substantially in its state of rest. It is also visible that the charging entity 3 is shifted or misaligned on the right inside the case E3. Indeed, the right edge of the cup G3 is in contact with the case E3, while its left edge where the tongue L3 is formed is detached from the case E3. Thus, a substantially annular space S4 in the shape of a crescent moon is defined between the cup G3 and the case E3. This annular space S4 is also defined around the grape B. The access profile G32 is located at the level where the cup G3 is in contact with the case E3. In FIG. 7b, the upper edge of sleeve C is already engaged inside case E3. It is then easy to understand that the G32 access profile will facilitate the engagement of the sleeve C around the bucket by shifting it to the left inside the E3 case. We can also say that this access profile G32 allows the upper edge of the sleeve C to make its way between the cup G3 and the case E3 by shifting it to the left, which has the effect of deforming the tongue L3. The sleeve C can then continue its insertion inside the case E3 by further deforming the tab L3, as shown in Figure 7c. The engagement of the sleeve in the case E3 thus makes it possible to change the annular space S4 from a crescent moon shape to a perfectly annular shape. It only remains for the user to move the pusher P3 to the bottom C3 of the window C1. The E3 case can be removed before or after this operation.

It should be noted that the elastic tongue L3 is not under stress inside the case E3, so that it does not risk being deformed by creep. The pusher P3 can be held in the notch E35 by wedging between these side edges or by a slight click, as previously described. The axial offset of the charging entity 3 inside the case E3 is not a problem, insofar as the sleeve C can still be inserted around the charging entity 3 thanks to the access profile G32 which avoids a straight stop of the sleeve C against the bucket G3.

The four embodiments which have just been described make it possible to highlight two important characteristics which can be implemented independently, namely the indentation of the case which makes it possible to accommodate the pusher therein and the annular space between the recharging entity and the case which makes it possible to engage the shirt around the recharging entity in order to pick it up. The engagement of the pusher in the window of the sleeve C, while the pusher is still fully engaged in the indentation of the case is another important feature of the invention. Similarly, in all the embodiments, the annular space is crossed by the pusher. The pusher can simply come into abutment against the bottom of the indentation and/or be locked against the bottom or close to the latter by any suitable reversible locking means, such as a tightening of the indentation, a thickening the edge of the indentation, the pressing of the tongue against the internal wall of the case, friction between the cup and the case, etc. We have seen that the bucket can be made of metal or of plastic material, with or without an elastic blocking tongue.

Thanks to the invention, there is a lipstick refill integrating a refill entity consisting of a cup and a grape which can be transferred from a case into the shirt of a lipstick mechanism sliding without risk of contact with the grapes. It is for example possible to envisage a box comprising a lipstick mechanism associated with several identical or different lipstick refills.
