Description

Cosmetic articles containing mesh

The present invention relates to a cosmetic article, in particular a lip cosmetic article.

Typically, the lipstick includes a tube and a cosmetic block, also referred to as raisin, which is vertically translationally received within the tube. Regrinding formulations are selected to provide better makeup effects while ensuring good strength, particularly mechanical strength and heat resistance, of the regrind. For this purpose, the ratio of the four main ingredients of the regimen, namely wax, oil, butter and pigment, can be adjusted. The wax acts as a structural component.

For example, in order to obtain a good makeup effect, such as color, gloss, or reinforced matte properties, it is desirable to reduce the strength of the regrowth, for example by increasing the ratio of oil and butter. In this case, a more smooth and smooth formulation can be obtained. However, this increase causes the mechanical strength of the regulator to be lowered, resulting in breakage. Moreover, this increase not only transforms the initial formulation of the regimen, but also causes exsudation, which has a negative visual impact on the consumer. In this regard, it should be recalled that the user has the potential to preserve such cosmetic articles for many years.

Therefore, an object of the present invention is to improve the cosmetic article.

To this end, there is provided a cosmetic article according to the invention, comprising:

A solid block of cosmetics having a breaking index of 0.2 to 20 N as measured at 20 < 0 > C, and

- at least one mesh arranged to pass the cosmetic product and having through holes with a maximum dimension of from 50 to 450 탆.

The rupture index reflects the mechanical strength of the block. In the case of having a value in the above-mentioned range, the solid block of the cosmetic product has a sufficient strength to limit the phenomenon that the impactor breaks down the stencil when the applicator falls during transportation or use, for example, in a handbag.

In use, the product block passes through the mesh and the mesh collapses the fraction of the product to change from a solid state to a paste state. This condition is particularly advantageous because it allows the product to be better applied. In the case of lipsticks, this particularly helps the user to make up, for example, with emphasis on color, gloss or matte properties.

In this way, the disadvantages of the solid form of cosmetics in use of the product, namely, the difficulty of application of the product, the less satisfactory make-up effect and the disadvantage of the paste-like product when the product is not used, for example low mechanical properties and exudation And has advantages of solid form of cosmetics at the time of non-use and a paste form at the time of use.

The range of maximum dimensions of the holes described above helps the user obtain good block collapse effects without giving too much effort to obtain the capacity required for makeup. In addition, the fact that the block is in particular a solid form aids the user of formulations which provide a good gloss or a particularly good matte effect which is incompatible with the softer form of the block. It is also particularly advantageous that, due to the aforementioned mechanical strength of the mesh and the nature of the pore size, there is no need to carry out another operation, for example a heating operation, on the product to pass the product from the solid state to the paste state .

The maximum dimension of the holes may be 100 to 400 mu m, preferably 150 to 350 mu m, more preferably 200 to 300 mu m.

Advantageously, at least one of the meshes is arranged such that the minimum edge to edge distance between the holes is 100 to 300 占 퐉.

This arrangement also contributes to obtaining a good collapse effect of the block without requiring the user to provide much effort. The minimum distance between different adjacent holes of the mesh may be provided such that it is not constant between the different holes. Also, a distribution of the minimum distance between adjacent holes of the mesh may be provided to help orient the product passing through the mesh in a desired direction.

The minimum distance between the holes may be 120 to 280 mu m, preferably 140 to 240 mu m, and more preferably 180 to 220 mu m.

Preferably, at least one of the meshes or meshes is woven.

Thus, the mesh consists of a warp and a weft.

These chambers may be provided to have different diameters. This particular arrangement allows the product to pass through the mesh, in particular, in a desired direction, for example, to help achieve a particular makeup effect.

At least one of the meshes or meshes may comprise a plate having apertures.

This mesh is obtained, for example, by machining, and imparts to the outline of the holes a shape that is difficult to obtain, for example, a circular shape, elongated shape or the like by, for example, weaving.

Preferably, all of the holes in one or more of the meshes or meshes have stacked contours.

Thus, the product paste is uniformly distributed on the mesh as it exits the holes, which helps to apply the product uniformly.

Advantageously, at least one of said meshes or meshes has apertures with non-staked contours.

Thus, the paste is concentrated at one or several specific locations on the mesh surface, so that certain effects can be obtained when applying the product or application of the product can be made more precise.

Preferably, the contours of the holes have a shape of one of a rectangular, pentagonal, hexagonal, octagonal, circular, elliptical or elongated shape.

Some of these different shapes also contribute to orienting the product while passing through the mesh.

More preferably, the article comprises two or more meshes along the direction through which the product passes through the meshes.

This feature has several advantages. When there are multiple meshes, it is possible to enhance the effect of each mesh guiding the product by orienting the product in a desired direction. This continuous mesh also helps to reduce the effort that the user has to provide to change a portion of the cosmetic block from a solid state to a paste state. Indeed, the upstream mesh collapses the first fraction of the product, which further collapses through the downstream mesh.

Advantageously, the two meshes form an upstream and a downstream mesh, the largest dimension of the holes of the upstream mesh being greater than the largest dimension of the holes of the downstream mesh, and the ratio between these two dimensions being greater than 1 and less than 100.

This feature makes it possible to easily switch the product block from a solid state to a paste state. In practice, the solid block product passes first through the mesh with the largest dimension holes, which collapses the block to convert the solid product into a paste product, through the mesh with the smaller dimension holes in the second step, This reduces the viscosity of the already pasty product so as to obtain a more easily applicable product and obtain a better make-up effect.

Advantageously, the article further comprises at least one intermediate mesh between the upstream mesh and the downstream mesh, the maximum dimension of the holes of the intermediate mesh being greater than the maximum dimension of the holes of the upstream mesh and the maximum dimension of the holes of the downstream mesh The maximum dimension is between.

Accordingly, the maximum dimension of the continuous mesh gradually decreases from the upstream mesh toward the downstream mesh. Thus, the energy required to convert the product block from a solid state to a paste state is reduced. Thus, the user provides less effort in using the article.

Advantageously, the cosmetic product is a lip cosmetic product.

Finally, preferably, the article

A body with a helical ramp,

A product dispensing tube having at least one rectilinear lamp, the product dispensing tube having a mesh located at a distal end of the tube,

A piston that allows the product block to slide within the tube, the piston being joined by two protrusions that can simultaneously traverse the helical ramp of the body and each of the straight ramps of the tube .

In this manner, as the user rotates the body relative to the tube, the protrusions of the piston cross the respective lamps and the piston slides vertically to pull the product block along the longitudinal axis of the article. This movement occurs without the piston rotating along the axis, and therefore the product block does not rotate at all. This feature is particularly advantageous because it facilitates passage of the product block through the mesh. In addition, the point at which the product is discharged without rotating has the advantage that it can impart a sloped shape to the tube, which is generally required because it facilitates makeup.

Hereinafter, the lip cosmetic article will be described with reference to Figs. 1 to 10. Fig. Below, the case of lipstick will be discussed. It will be appreciated that the lip cosmetic article may be different and is not limited to red lipstick, and that the color of the cosmetic may be pink, black, beige or the like.

Device

The outer shell of the cosmetic article 1 shown in Fig. 1 is formed of a body 2 and a lid (not shown). The body has an abutment formed by a shoulder and the lid can be supported thereon such that the body partially fits into the lid.

The body includes two cylindrical portions, for example two cylindrical portions having a substantially square cross-section in the cross-section of the applicator body, the second portion having reduced dimensions compared to the first portion. These two parts are separated by a pedestal. The body is hollow and its distal end and proximal end are open. The opening 11 in the proximal end of the body is partially obstructed by a part of the base 3 of the body extending from this end in the transverse plane of the applicator body.

The cavity formed by the body 2 comprises a tubular member 4, a tube 5 and a piston 6 with a helical ramp from the outside to the inside in the direction of the axis 13 of the body And their major longitudinal axes 13 are joined.

The tubular member 4 (see FIG. 7) is a generally hollow cylindrical shape having a circular cross section in a plane perpendicular to the longitudinal axis 13, and both ends open. The tubular member (4) has an inner surface with a substantially flat outer surface and a groove forming a helical ramp (7) extending over most of the length of the tubular member (4). In Fig. 7, eight spiral rotations can be identified. It will be appreciated that a different number of helical rotations may be provided, i.e. more or less helical rotations, depending on the desired effect. This member rests on a portion of the base portion 3 by its proximal end. The distal end of the member 4 extends substantially in the pedestal. This member is firmly fixed to the body 2 of the article.

The tube 5 (see FIG. 6) forms a hollow cylinder having a circular cross-section in a plane perpendicular to the axis 13, both ends of which are open. The distal end of the tube 5 is tapered. It will be appreciated that this end may be provided so as not to be tapered. The tube 5 has two notches forming two lamps 8 extending from the proximal end of the tube to the middle of the tube. The lamps are generally straight and extend parallel to the axis (13). They are opposed to each other in the radial direction on both sides of this axis.

The piston 6 (see Fig. 5) forms a hollow cylinder having a circular cross section in a plane perpendicular to the axis 13. [ The proximal end of the piston is open, its distal end tapered, and closed by a slightly lower portion 9 relative to the distal end of the piston, forming a vessel into which the base of the spring engages. This improves the coupling between piston and piston. In Figure 1, the portion 9 of the piston that closes the distal end is flat and tilted relative to the shaft 13 to also taper. The piston has two diametrically opposed guidance pads 10 on the outer surface of its proximal end that project from the outer surface of the piston. Of course, the pads may be disposed at different positions on the outer surface of the piston. These pads can simultaneously traverse the straight ramp 8 of the tube 5 and the helical ramp 7 of the tubular member 4 simultaneously. Optionally, the piston has, at its distal end, a sealing lip 12 that extends over the entire circumference of the distal end of the piston. Other guiding means may be provided.

The proximal end of the tube 5 is thus received in the body and the tubular member 4 and its distal end extend outward and protrude out of the body 2 of the article 1. [ The tube is rotatably mounted about the shaft 13 with respect to an assembly formed by the body 2 and the tubular member 4 by suitable guiding means. The piston 6 itself is slidably received in the tube 5 by pads 10 which can cross the different lamps 7, 8.

The article 1 also comprises a lipstick or regrind solid block 14. The strike 14 has a generally cylindrical shape with a circular cross section in a plane perpendicular to the axis 13. [ The distal end of the prong (14) has a tapered shape. Of course, these ends can be provided in different shapes, and these shapes are well known to those skilled in the art. The prong (14) lies on the distal end (9) of the piston (6) by its proximal end. Thus, the piston can make the struts 14 slide along the shaft 13 within the tube 5.

This streak has a breaking index of 0.2 to 20 N (about 20 to 2000 g-force) as measured at 20 占 폚.

This measure is measured, for example, at a rod descent rate of 132 mm / min by a reference test bench TCM 201M and a reference force sensor 23 (dynamometer) DFS 5 kilogram-force (KgF) . The breaking rupture index of a competition represents the average force that must be applied to break the competition.

Since the temperature of the product directly affects the measurement result, the temperature of the product is controlled for the measurement. Before the measurement, the temperature can be adjusted to a desired temperature according to a known method. For example, the striae can be stored in a temperature control chamber at 20 ° C or in a room controlled at 20 ° C. To ensure that the temperature of the product is between 19.5 ° C and 21.5 ° C, the temperature of the product is measured using a thermometer inserted in the center of the stirrup before the measurement.

Typically a force sensor of 1 or 5 KgF can be used. A 1 Kg force sensor can measure up to 1000 gF (approx. 9.8 N). If this value is exceeded, a 5KgF sensor should be used.

Referring to FIG. 10, the measurement is performed with a tube 24 of the same diameter as the tube 5. The tube 24 lies horizontally with respect to the reed 14 in its outermost position as far as possible from the article. The tube is held stationary by a retaining ring 20 and a setscrew 21, with the tapered side of the spring facing downward (see FIG. 10). A rod 22 comprising an inverted "V" shaped pedestal descends vertically at a programmed rate, i. E. 132 mm / min in this case, until it comes into contact with the stalk 14 and breaks. The dynamometer 23 provides a value corresponding to the maximum compressive force measured at the time of damage of the spring, i.e., the breaking index. A number of tests may be performed on the streaks of the same formulation to calculate the mean and standard deviation of the rupture index.

The article 1 also comprises one mesh 15 of generally circular shape. In the illustrated embodiment, the mesh is a woven mesh of, for example, metal, including warp yarns 18 and weft yarns 19, which form apertures 16, which are generally rectangular in shape. The fact that the mesh is made of metal is particularly advantageous because it gives the user a pleasant "refreshing" effect when applying the product to the lips. The maximum dimension d of the holes 16, i.e. the diagonal dimension of the holes 16 here, is between 50 and 450 μm. The warp yarns and the weft yarns have diameters (a, b) of 100 to 300 mu m, and thus also correspond to the value of the minimum distance between the holes. The mesh 15 is securely fixed to the distal end of the tube 5 via a support 17. In this example, the holes are as follows:

- Maximum dimension: 280 탆,

- Width: 100 탆,

- length: 261 탆,

- diameter of the warp yarns a : 150 탆,

- diameter of weft b : 100 탆,

The distance between the holes: 100 mu m.

The support (17) has a generally cylindrical shape with a circular cross section in a plane perpendicular to the axis (13). The mesh 15 is connected to the support 17 by, for example, overmoulding the support onto the mesh, and the support is made of plastic. The support is connected to the tube 5, which connection is made on the entire circumference of the distal end of the tube.

Figure 4 shows a mesh that is alternatively fabricated by machining, and thus the holes 16 may have any suitable shape, such as circular, elliptical or other shapes.

work

When the applicator is not used, the piston 6 is located at the lowest position. That is, its proximal end contacts the portion 3 of the article. The struts 14 are positioned opposite to each other with a distance from the mesh 15 (not shown).

In use, the user holds the article 1 with both hands. One hand holds the end of the tube 5 projecting from the body of the article and the other hand holds the largest dimension of the body 2 of the article.

The user causes the body 2 of the article to rotate about the axis 13 about the tube. This rotational movement causes the two guide pads 10 of the piston to cross the spiral ramp 7 of the tubular member 4 and the straight ramp 8 of the tube 5. This traversing causes translational movement or linear sliding of the piston 6 along the axis 13, which pulls the striker 14. The translational motion continues until the strike 14 contacts the mesh 15.

The user causes the body 2 of the article to continue to rotate so that the ends of the stitches 14 pass through the mesh 15. This passage through the mesh disrupts the fragments of the solid comb end and breaks them into fine pieces which pass through the mesh and bond on the mesh to form a homogeneous paste. When the regimen passes through the mesh and collapses into a paste, the paste is ready for application. Therefore, the user can easily apply the paste to the lips. Of course, for each application only the end of the product block collapses and most of the competition remains intact. As the block moves towards the mesh, it gradually collapses gradually as the application progresses.

8, the article 1 comprises two meshes 15 at the distal end of the tube 5, the two meshes being in contact with each other and on the same support 17 . The two meshes are parallel to each other and oppose each other.

In use, the striae pass through the downstream mesh immediately after passing through the upstream mesh.

This arrangement has several advantages. In practice, this helps to further disrupt the product blocks and thus to obtain more liquid pastes. Also, the effort to pass a portion of the strip through the meshes is reduced, especially if the maximum dimension of the holes 16 in the proximal or upstream mesh is greater than the maximum dimension of the holes 16 in the distal or downstream mesh . The ratio between these two dimensions is greater than 1 and less than 100, for example 60.

These two meshes 15 may be composed of the same material or different materials. The two meshes may also have holes 16, the contours of which have different shapes within the same mesh 15 or between the two meshes. For example, the first mesh may have a shape in which the hole contour is rectangular, and the second mesh may be provided in such a manner that the hole contour has a generally elongated shape. It will be appreciated that a greater number of meshes may be considered, for example 3 meshes, 4 meshes, 5 meshes or 6 meshes.

In another embodiment shown in Fig. 9, the article 1 comprises two meshes 15 which are adjacent and not facing each other but not in contact with each other. The spacing between these two meshes is suitable to accommodate the striae until the striae pass through the first mesh, that is, through the proximal mesh and then through the second mesh. This spacing between the two meshes can be maintained, for example, by braces.

The advantages of this embodiment are the same as those of the previous embodiment. This, in turn, helps to reduce the effort that the user has to provide in order to obtain more liquid paste products and to convert solid streaks into liquid pastes. As in the previous embodiment, a greater number of meshes may be considered, for example, three meshes, four meshes, five meshes, or six meshes. These two meshes 15 may be composed of the same material or different materials. These two meshes may also have holes 16, the contours of which have different shapes within the same mesh 15 or between the two meshes. For example, the first mesh may have a shape in which the hole contour is rectangular, and the second mesh may be provided in such a manner that the hole contour has a generally elongated shape.

It is to be understood that various changes and modifications may be made without departing from the scope of the present invention.

The embodiments described above use a mechanism to help transport the pistol. Any mechanism known to those skilled in the art can be used. For example, the linear lamp may extend outside the part having the spiral lamp. However, the configuration in which the spiral ramp described with reference to the figures is external to the rectilinear ramp reduces the pitch of the spiral, thus reducing the effort that the user has to provide to pass stitches through the mesh or meshes .

A mechanism may be provided that allows the user to directly provide a sliding movement for lifting the rivalry.

A mechanism may be provided for securely securing the struts to the body, which may be meshes or meshes that descend over the struts to disrupt the struts.

One of the meshes or meshes is not woven, but can be provided by machining the plate to make holes or even to be manufactured by an additive manufacturing technique (3D printing).

The dimensions and / or distribution of the holes may be provided to vary on the surface of the mesh.

The holes may also be provided to have larger dimensions than the other holes to disrupt more formulations in one direction.

The mesh may be provided concave or convex.

The mesh may be composed of plastic, cloth or metal.

The cosmetic may be for other parts of the face. This is particularly applicable to the whole body. This may be related to lipstick and different cosmetics, such as care products.
