Summary of the Invention

Problems to be Solved by the Invention

[0006] When the stick is used up, in order to reuse the case with a new mechanism, it is necessary to prompt the user to hold the case and at the same time obtain benefits from a device for packaging and applying lipstick that is attractive to consumers.

Means for Solving the Problems

[0007] The present invention is a device for packaging a cosmetic product in the form of a stick, particularly lipstick, - a dispenser mechanism having a proximal portion and a rotatable distal portion, the rotational movement of the distal portion relative to the proximal portion being configured to occur simultaneously with the axial movement of the stick relative to the proximal portion, - a case having a body made of mineral glass into which the mechanism can be fitted and fixed and is satisfied by a device having.

[0008] Since glass is a material that is difficult to damage, the use of mineral glass provides durability and enables the case to be reused without worrying about deterioration of its aesthetic appearance.

[0009] Moreover, the case can be easily cleaned if necessary.

[0010] Due to its weight, the case also provides stability in the vertical position, thereby enabling it to be stored vertically together with other products or accessories.

[0011] Also, when the main body is transparent, the case enables the color of the stick to be seen through the case without the need to remove the case, thereby saving the user's time when the user needs to select among several products.

[0012] Also, the glass provides effective protection against ultraviolet rays, lateral and axial mechanical pressures, and gives the case a pleasant cool feel.

[0013] The case can be made with outer dimensions such that it has a certain degree of compatibility for use on existing display stands.

[0014] The mechanism is known per se and includes any system for converting a rotational movement into an axial movement. A number of mechanisms are commercially available. Examples of mechanisms are described, inter alia, in Patent Document 7 and Patent Document 8.

[0015] The glass body has a neck portion, and the case preferably has a ring made of a thermoplastic material, which is attached and fixed to the neck portion and to which the mechanism is fixed. Such a ring makes it possible to manufacture a body with fairly large manufacturing tolerances and at the same time enables accurate mounting of the mechanism on the case.

[0016] The ring may have at least two fixing tabs on the neck portion, and more preferably four.

[0017] The neck may have at least one positioning relief, especially tooth-shaped, on its outer surface, and at least one of the fixing tabs of the ring may have a recess for receiving said relief.

[0018] At least some of the fixing tabs have snap-fastening teeth on their radially inner surfaces, and the recesses are formed by interruptions of the teeth. The neck portion may have positioning reliefs on two diametrically opposite sides, and two of the fixing tabs of the ring have corresponding recesses.

[0019] The case preferably has a cover, also called a "cup", which is particularly made of metal and is designed to be fixed to the ring. This cover is involved in the appearance of the case and may also have the function of holding the ring.

[0020] The cover can be fixed in various ways.

[0021] The fixing tabs may have ribs for holding the cover on their outer surfaces, against which the cover abuts. The cover, by carrying the tabs, keeps the tabs on the neck portion, thereby making it more difficult to accidentally remove the ring.

[0022] Also, the ring may have at least one relief that is designed to snap - fasten with at least one corresponding relief of the cover. For example, the tabs of the ring have at least one protruding relief, and the skirt of the cover has at least one relief that defines at least one housing into which this protruding relief is received. In one example, the skirt of the cover has an end portion that is folded onto itself adjacent to the inner surface of the cover, which is for defining the said housing for receiving the relief on the ring above this fold. The skirt of the cover may have a shoulder portion that axially abuts against the said relief above the fold. This, together with the fold, should form the above - mentioned housing for receiving the relief. The relief can be formed by ribs that are integrally molded with each tab of the ring. A chamfer may extend under the rib to form a space for accommodating the fold.

[0023] The lip portion of the ring may be completely flat and may rest on top of the uppermost part of the annular portion of the ring, which may also be flat. In this case, the radially inner edge of the lip portion of the cover may be at a short distance (e.g., less than 1 mm measured radially) from the radially inner edge of the annular portion of the ring.

[0024] Also, the ring may have positioning ribs on its upper surface that form upward protrusions, and the cover may substantially abut against these ribs at its radially inner edge. It is preferable that it is placed close to the radially inner edge of the annular portion of the ring. Such ribs improve the centering of the cover on the ring. The fact that the lower edge of the lip portion of the cover thus retreats from the opening provides ease of assembly, snap fastening, and centering.

[0025] Optionally, the positioning rib and the cover have mutually supporting edges that are complementarily angled, and the support of the cover on the groove portion helps to axially hold the edge of the cover in contact with the annular portion of the ring. The positioning rib may particularly have an upwardly outwardly inclined edge. Further, in this way, the mechanism is enabled to axially abut against the cover before abutting against the ring, which is advantageous when the cover is made of metal.

[0026] The lip portion of the cover may have an inwardly downwardly inclined portion close to its radially inner edge, and this portion may advantageously come into contact with the above-described positioning rib. Such an inclined portion may keep the lip portion of the cover separated from the annular portion of the rib except for the contact area between the lip portion of the cover and the ring. This contact area may be defined by the lower edge corner of the inclined portion, and the inclined portion may contact the positioning rib at its upper edge corner. Such a limited contact between the cover and the ring makes assembly easier.

[0027] The mechanism may have a base, particularly a metal base, into which the proximal portion is received, and this base is designed to be snap-fastened onto the case. The base may have a tubular skirt provided with fixed reliefs designed to be snap-fastened to the ring.

[0028] These fixed reliefs may be in the form of bosses, and the snap fastening is preferably realized on the radially inner circular edge of the ring.

[0029] The glass body is preferably transparent. The body can be made from recycled glass or glass containing a certain proportion of recycled glass, for example at least 20%.

[0030] A further object of the present invention is an assembly and a replacement mechanism having at least one device according to the present invention. If necessary, two can be packaged together. Also, the replacement mechanism may be packaged separately.

[0031] The present invention can be better understood by reading the following detailed description of its non-limiting embodiments and by considering the accompanying drawings.

Best Mode for Carrying Out the Invention

[0033] Figure 1 shows a packaging device 1 according to the present invention, having a lipstick mechanism 2 and a case 3 in which the mechanism can be fixed when the lipstick is not being used for application.

[0034] In the conventional method, as shown in Figure 3, the mechanism 2 has a proximal portion 25 and a rotatable distal portion 22 that can rotate relative to the proximal portion 25 in order to axially move a stick holder cup (not shown).

[0035] The proximal portion 25 is received within a base 21, such as a metal base, shown in Figure 2, and the proximal portion is press-fitted and / or snap-fastened, etc. to the base, for example.

[0036] As shown, the proximal portion 25 may be provided with an anti-rotation relief 29 at its end.

[0037] The base 21 has a longer diameter gripping portion, for example provided with a surface grating as shown, and a tubular mounting skirt 23 provided with bosses 24, for example three bosses equally distributed at 120° to each other about the longitudinal axis of the mechanism. The outer diameter of the skirt 23 is, for example, 15 mm or less, for example about 14.5 mm.

[0038] The base 21 cooperates with the relief 29 so that the proximal portion cannot rotate relative to the base 21.

[0039] The case 3 has a body 31 made of, for example, clear mineral glass, and the mineral glass has a neck portion 32 at its upper end to which a ring 40 made of a thermoplastic material and covered with a metal cover 50 is fixed on top, as shown in Figure 4. The body 31 is closed at its lower end by a flat bottom surface.

[0040] The neck portion 32 has a collar forming a radially outwardly projecting portion that defines a groove portion 33 around the neck portion 32 into which two diametrically opposed positioning reliefs 34 in the form of tooth projections project. Only one of these reliefs 34 is shown in FIG. 4.

[0041] The body 31 has, for example, a square outer cross-section with rounded corners below the shoulder portion at the base of the neck portion 32.

[0042] Referring more particularly to FIGS. 5 and 6, it is apparent that the ring 40 has four fixing tabs 41 connected at the top to an annular portion 42.

[0043] The outer shape of this annular portion 42 is substantially a square with rounded corners, and each tab 41 is located at a corner.

[0044] Each tab 41 has, on its radially outer surface, a series of parallel ribs 44 extending in a respective plane oriented perpendicular to the longitudinal axis of the case, and, on its radially inner surface, snap-fastening teeth 45.

[0045] The teeth 45 of the tabs 41 diametrically opposed to each other are interrupted to define recesses 46 for the positioning reliefs 34 on the neck portion 32 to engage therein, as shown in FIG. 8. These reliefs 34 prevent the ring 40 from rotating relative to the neck portion 32 when they are engaged within the recesses 46.

[0046] A slot 48 is provided through the annular portion 42 for the passage of a mold for forming the teeth 45 during the manufacture of the ring 40 by injection molding.

[0047] The cover 50 has an outer skirt 51 carried on the ribs 44 of the tabs 41 to ensure its retention.

[0048] To assemble Case 3, the ring 40 can be snap-fastened onto the neck portion 32, and then the cover 50 is engaged onto said ring 40. In a variant form, the ring 40 is disposed within the cover 50 to form the assembly shown in Figure 7, and then the assembly is snap-fastened onto the neck portion 32.

[0049] The annular portion 42 of the ring 40 defines a circular opening 47, the diameter of which is slightly larger than the diameter of the fixed skirt 23 of the base 21. Thus, as shown in Figure 10, the fixed skirt 23 can be snap-fastened by the boss 24 on the edge of this opening 47.

[0050] In the variant form shown in Figure 11, the annular portion of the ring has an annular positioning rib 60, and the annular positioning rib borders the opening 47. This rib 60 is formed by injection molding together with the rest of the ring 40. The rib may have a radially outer flank 61 that slopes slightly upward and outward.

[0051] The cover 50 has a lip portion 55 that extends to the level of the flank 61. This lip portion is formed, for example, as one piece with the rest of the cover 50. The lip may have a radially inner edge 56 that is slightly beveled at the same inclination as the flank 61 to allow two of them to have complementary shapes and one edge to fit within the other.

[0052] Preferably, the thickness t of the rib 60 in the direction of the longitudinal axis of the device is equal to the thickness of the lip portion 55, as shown in the figure.

[0053] As shown in the figure, the upper surface 57 of the lip portion 55 can be placed slightly higher than the upper surface of the rib 60.

[0054] In the variant form shown in Figure 12, the lip portion 55 of the cover 50 has a flat annular portion 57 that is oriented perpendicular to the longitudinal axis of the device, and it is extended by an end portion 58 that slopes inward and downward.

[0055] As shown in the figure, the end portion 58 may rest on the annular rib 60 around the rib 60, abutting against the annular rib 60 at one edge corner 58a and against the uppermost part of the annular portion of the ring at the other edge corner 58b.

[0056] Figure 13 shows the possibility of realizing the retention of the cover 50 by the ring 40 by some other means than by the friction of the rib 44.

[0057] In this example, each tab 41 has a retaining rib 70 near its lower edge. Each tab 41 has a chamfered portion 72 under this rib 70.

[0058] The outer skirt 51 of the cover 50 may have a thinner lower portion 78 that is folded inwards on itself at its lower end to define a folded portion 75 that is disposed under the rib 70 to keep the cover 50 on the ring 40.

[0059] The joint between the lower portion 78 and the rest of the cover 50 may define a shoulder portion 79 that axially abuts against the rib 70.

[0060] In this example, as shown in the figure, the upper surface of the ring 40 may be flat, and the lip portion 55 of the cover abuts against the uppermost part of the ring at its lower surface 55a.

[0061] During the attachment of the cover 50 on the ring 40, the rib 70 fits into the groove formed between the folded portion 75 and the shoulder portion 79 to ensure that the cover 50 is connected to the ring 40.

[0062] The presence of the chamfered portion 72 liberates space under the rib 70, which enables the accommodation of the folded portion 75.

[0063] The tab 41 of the ring 40 carried on the outer skirt of the cover 50 above the rib 70 may have a thickened portion 80 to achieve a desired radial clamping between the cover 50 and the ring 40. The cover 50 can, as shown, abut against the shoulder portion 38 of the main body 31 at its lower end portion 51b at the base of the neck portion 32.

[0064] To use the mechanism 2, the user pulls it out of the case 3: the elasticity of the plastic material of the ring 40 allows the boss 24 to pass through the ring. Next, the user can hold the base 21 between two fingers and rotate the distal portion 22 to extend the stick.

[0065] After use, the mechanism 2 is inserted into the case 3 until the boss 24 is snap - fastened to the ring 40.

[0066] When the stick is used up, the user can hold the base 21 and the case 3 and replace the mechanism 2.

[0067] Of course, the present invention is not limited to the examples described herein.

[0068] For example, the glass body 31 can be manufactured with a shape showing rotational symmetry.

[0069] If necessary, the mechanism 2 is manufactured without the base 21, and the mechanism is a proximal portion configured to be directly fixed to the ring 40.

[0070] The cover 50 can be made of a plastic material.

[0071] The mechanism 2 can be fixed to the case 3 by sealing, for example, by providing a flexible seal.
