Description

The invention relates to a scraper for stripping a cosmetic applicator when pulling out of a reservoir according to the preamble of claim 1.

Cosmetic applicators and especially mascara applicators protrude when not in use in a reservoir in which the cosmetic to be applied is. This ensures that the cosmetic applicator is available in plenty wetted with the cosmetic form. In many cases, the wetting of the cosmetic applicator is reinforced by the fact that the cosmetic unit is not only "cover up and bottom down" in the domestic bathroom on the counter of the washstand, but in mobile use and is taken for this purpose in the purse ,

Because of this, it must be ensured that the cosmetic applicator, when withdrawn from the reservoir, is always wetted with just the right amount of cosmetic and does not "pull" excess cosmetic from the reservoir.

Scrapers are usually provided for this purpose.

Such scrapers usually, in the broadest sense, the contour and function of an anus, d. H. they have an annular wiper lip, which lays tightly around the shaft of the cosmetic applicator, with the aid of which the cosmetic applicator protrudes into the reservoir when not in use.

Once the wiper is pulled out of the reservoir, the excess amount of the cosmetic adhering to the applicator shaft and the actual applicator, stripped off.

Such annular scrapers are well manageable in practice and therefore no longer cause difficulties, since suitable scraper designs are available for a wide variety of applications. More recently, however, there has been a growing demand for alternative cosmetic applicators that provide a completely novel sensation of use. In the course of this cosmetic flat applicators have been developed, especially for the purpose of mascara application, the appearance of which rather corresponds to a brush, but which are designed such that they closer to the application advantages of the classic Mascaraapplikatoren and in particular their brush-like behavior, which is an excellent Combing and separating guaranteed, with the often felt beneficial handling of a brush and with its attractive, fresh design.

The construction of scrapers for such Flachapplikatoren brings some challenges with it. Because with such flat applicators, the length of the contact line between the scraper and the applicator is many times greater than in the known applicators, which is why a much greater friction occurs, which makes the wide and therefore much more unstable scraper much more likely, for example, to "stowed" and then only unfold an unsatisfactory wiping effect.

It has already been attempted internally to counteract this undesirable "puckering" by making the scraper as a whole stiffer. However, this leads to the fact that considerable forces have to be applied by the user in order to extract the cosmetic applicator to the outside through the stiff scraper which unfolds due to its long contact line and relatively high frictional forces. It can hardly be avoided that when pulling out of the applicator a jerky, haptic impression arises because the forces required to pull out the applicator suddenly become significantly lower as soon as the applicator has come out of engagement with the wiper.

The patent US 5,309,929 proposes a scraper, the opposite wiper lips are broken down into individual bending elements. Between a double pair of laterally adjacent and opposing bending elements here remains a relatively large space open so that the cosmetic composition, although it is typically pasty, can overcome the barrier effect of the scraper to a significant extent.

EP1481607A describes a wiper with wiper lips. An at least equally serious problem is that such flat applicators, especially when they are used to apply mascara, have a bristle trim that can be easily damaged by a too stiff scraper.

In light of this, it is the object of the invention to provide a scraper for a Kosmetikflachapplikator, which has an improved effect, in particular in the form of a better characteristic when pushing in and pulling out the flat applicator.

This object is achieved with the features of claim 1.

The solution is achieved in that the scraper forms a preferably substantially rectangular passage which is blocked in the unloaded state by two opposing wiper lips, each in turn divided into a plurality of bending elements which are elastically deformed when pushing through the cosmetics applicator and thereby the way for release the passage of the applicator through the passage.

In this case, the invention usually provides that the wiper lips in the unloaded state in the direction of their longitudinal axes LS 1 and LS 2 have an at least substantially, preferably even up to tolerance-related deviations or due to the service life deformations completely rectilinear course. A substantially straight course may be mentioned if the mean radius of curvature of the longitudinal axes is less than 40 mm and preferably even less than 60 mm. Preferably, said longitudinal axes LS 1 and 2 extend parallel to the parting line T between the wiper lips.

Also, a passage whose edges have a slight wavy line or whose edges correspond only approximately to a rectangle, because they are convex or convex, but still form a rectangle substantially, is a rectangular passage in the context of the invention.

It is provided that the bending elements form a first portion of the wiper lip and pass into a foot portion of the wiper lip, which forms the second portion of the wiper lip and in this way prevents the wiper lip is too soft. Such a "two-part" or divided into two sections wiper lip retains its usual hardness in the foot and takes into account only in its outer region by means of the bending elements consideration for the kink sensitivity of the bristles.

The bending elements are designed as triangular tongues. There is a gap between each of these triangular tongues. Predominantly or exclusively triangular tongues are favorable because of their ability to better direct passing applicator bristles.

The triangular tongues of opposing wiper lips are arranged with offset repeat or offset. In this way it is prevented that always two columns opposite each other between opposing pairs of triangular tongues and thus form too large open spaces over which the barrier effect of the scraper can be overcome by the cosmetic.

A preferred embodiment provides that two or preferably a plurality of bending elements of a wiper lip following its root to a common

Combine rag. In this case, a wiper lip then consists of a plurality of lobes, which preferably do not touch one another or at least do not touch over a more than insignificant part of their flank.

By forming such flaps, the flexibility of the wiper lip is further lowered, d. H. The wiper lip becomes more supple. At the same time vents are preferably created through which the interior of the cosmetic reservoir is in communication with the outside environment, so that when pulling out of the scraper no or no significant negative pressure forms and conversely forms no or no significant overpressure when pushing the scraper.

In another preferred embodiment, it is provided that the longitudinal axis of the bending elements is inclined relative to the longitudinal axis of the scraper by an angle of 82 ° to 50 °.

Within the scope of a further preferred embodiment, it is provided that the thickness of the bending elements (measured approximately in the direction of the longitudinal axis of the wiper) is reduced from the root of the bending element to the free end of the bending element, preferably by at least 10%, ideally by at least 25%. the thickness of the bending element at its root.

In a further preferred embodiment, it is provided that the narrowest side of the triangular tongues forms their root, with which the triangular tongues are respectively connected in the manner of cantilevered bending beams to the rest of the body of the wiper or to the foot portion of the wiper lip.

In principle, it is conceivable that the bending elements in turn have the shape of closely spaced and preferably arranged in several rows in the insertion direction one behind the other bristles. The bending elements can thus each represent a substantially as a linear bar presenting bristle curtain, single bristles with a foot diameter ≤ 0.2 mm defined in more detail below. The bristle distances result from the required wiping effect and are to be determined by conventional experiments. Preferably, molded bristles are used.

Clearly preferred, the flexures are not bristles, but significantly more massive. Then, at least in their foot region, in which they pass into the stripper base body (distal from a possible groove / rounding between the bending element and the stripper body), in the direction of the maximum usable length LM, they have a width which is ≥ 0.4 mm, better ≥ 0 , 8 mm and partially ≥ 1.5 mm. Further advantages, effects and design options will become apparent from the following description of the three embodiments explained by the figures.

How to use the Fig. 1 to 3 sees, the main part of the scraper 1 forming stripper body 2 is designed as a sleeve which surrounds a passage 3 for a cosmetic applicator, not shown, which extends in the direction of a longitudinal axis L. The scraper can be described as rectangular with rounded corners if necessary. It is essential that the scraper two short sides and substantially at right angles to two long sides, which are at least a factor of 1.5 even better by at least a factor of 1.8 and ideally by a factor of 2 longer than the short sides. Of course, especially the long pages do not have to be straight in the mathematical sense straight, they can for design or patent reasons, for. B. also have a slightly wavy design, without leaving the concept to be understood in the broad sense "rectangular" - even if such a design is only peripherally according to the invention, since associated with increased manufacturing costs.

The scraper according to the invention to be used for the cosmetic sector differs from scrapers, which are used in other technical fields for completely different purposes, not least by its delicate design:
The sleeve has a maximum height HM of up to 22 mm, better up to only 18 mm, but preferably the maximum height HM is limited to 13 mm. The scraper main body 2 is designed such that the passage in a first direction perpendicular to the said longitudinal axis L a usable maximum length LM of 15 mm to 55 mm, or from only 15 mm to 40 mm, preferably only from 15 mm to 30 mm.

In a second direction perpendicular to the first direction and to the longitudinal axis, the passage has a maximum usable width BM of 2.5 mm to 10 mm, preferably 3 mm to 8 mm.

How to use the Fig. 3 sees, the passage in the unloaded state, ie when not used cosmetic applicator, by two - preferably only two - opposite wiper lips 4 and 5 blocked. These stiffening lips are each composed of a foot section 6 or 7 and an actual lip section 8 or 9 together. The wiper lips are characterized by the fact that they are essentially designed as straight strips which enclose an imaginary linear separation line T between them. For patent law reasons, such dividing lines according to the invention, which are only average on average, because they are for. B. on closer inspection slightly serpentine around a center line around.

The wiper lips are connected with their foot to the Abstreifergrundkörper, preferably molded. They are preferably made of the same material as this. Alternatively, in some cases where an optimally adjusted result is to be achieved without regard to cost, it will be desirable to spray the wiper lips using another, preferably more flexible, plastic.

The wiper lips are designed so that they are connected to one of its two longer sides to the Abstreifergrundkörper. The other of the two longer sides is the substantially cantilevered side of the wiper lip. The longer sides of these wiper lips are preferably at least 10 mm, more preferably 15 mm and ideally even more than 20 mm long in the direction of the arrow P. Preferred embodiments even have wiper lips whose longer sides are at least 25 mm long.

The lip portion 8 and 9 and at least one of the two wiper lips 4 and 5 are each divided into a plurality of bending elements 12. In the present embodiment, even the lip portions of both wiper lips are divided in such a way.

The wiper lip thus subdivided preferably has at least 10 bending elements (with the reference numeral 12), better at least 20 and ideally more than 25 bending elements. The use of more than 40 bending elements worsens in most cases, the properties of the scraper again, which can be accepted at best in exceptional cases and should preferably be avoided.

For many applications, it is ideal if the bending elements 12 are largely predominantly or ideally completely identical. As a rule, the bending elements are designed so that they assume a defined shape and position - unlike, for example, a single bristle in the narrower sense, i. H. also at the latest after repeated use of confused filaments of existing scrapers.

These flexures 12 are characterized by the fact that they can be bent aside individually when pushing or pulling the cosmetic applicator without immediately transferring forces to an adjacent bending element. These bending elements 12 are preferably configured on the one side on their side of the foot section tailed, freely projecting into the central region of the scraper bending beam. These bending beams are very filigree in comparison to the maximum passage length LM, because the average width does not exceed the dimension of 1.5 mm and better still the dimension of 0.75 mm. A mean width in this sense means that width parallel to the maximum passage length LM, which would have a thought rectangle, which has the same surface as a bending element between its free end and the point at which it like a Kragträgers to the foot section the associated wiper lip is connected. Such an embodiment, in the best case, all or at least the overwhelming number of bending beams.

Between the individual, adjacent bending elements 12 one and the same wiper lip 4 or 5 preferably a certain gap 10 remains free, d. H. In any case, adjacent bending elements 12 do not touch each other with their flanks over their entire length, preferably not at all. Precisely because of this, it is so that the individual bending elements 12 can be bent aside to a certain extent individually, without immediately transferring forces to an adjacent bending element.

It is known that it is not desirable for cosmetic mass initially located in the reservoir to overcome the barrier effect of the scraper and to penetrate into the region of the closure cap of the cosmetic container in the case of unfavorable storage of the cosmetic container (eg headstand in a handbag). In order to take this into account, depending on the rheological properties of the cosmetic for which the wiper is intended, all or at least substantially (which is significantly less favorable), the gaps 10 are kept so small that the cosmetic, due to its high viscosity and / or surface tension can not substantially overcome the gap if the cosmetics container is stored in the head stand for at least 4 hours.

Based on Fig. 1 it can be seen that the wiper lips 4, 5 or at least their bending elements 12 are arranged in the direction of the interior of the cosmetic container in a direction swept relative to one another - the arrowhead faces the interior of the cosmetic container. Preferably, the lip longitudinal axis LL encloses, at least on the half of the wiper lip 4, 5 facing the middle of the passage, an acute angle W with the longitudinal axis L of the passage 3, for which W ≦ 70 ° or, ideally, W ≦ 65 °. The angle should preferably not be less than 50 °.

As based on the Fig. 1 and graphically explained in more detail with reference to the extent identical Fig. 7 Preferably, the wiper lips have a slight curvature in the direction from the root to the tip of the wiper lip, with a radius of curvature Q. For: Q ≤ 50 mm, better Q ≤ 40 mm, ideally Q ≤ 20 mm.

It makes sense that the wiper lips 4, 5 or at least their bending elements 12 taper towards the center of the passage, at least in their width and / or thickness, so that their area-moment of inertia opposing a bending becomes ever smaller towards the center.

As can be seen, these bending elements 12 are preferably formed as triangular tongues, of which a number along a wiper lip 4 and 5 is arranged side by side.

For these triangular tongues and the column 10 located between them, all the words above apply literally.

The tips of these triangular tongues collar freely. Between adjacent tongues are triangular columns. The triangles forming the tongues are triangles with an acute-angled side that projects freely. The width of the triangles in the direction of the maximum usable length LM is between 0.4 mm and 1.5 mm in the root region of the freely projecting triangle, preferably the upper limit of the width is even ≦ 0.9 mm.

The triangular tongues are arranged on their opposite Abstreiferlippen with offset repeat or offset, ie the tips of the triangular tongues of a wiper lip are each directly (by the shortest route) the free spaces between two triangular tongues of the other wiper lip opposite. This avoids that local free spaces arise, which have such a large free cross-sectional area that the barrier effect of the scraper addressed elsewhere in this description is impaired.

The triangular tongues are particularly of great advantage when it comes to strip a Flachapplikator whose bristle stocking has a cylindrical in the broadest sense envelope contour, d. H. the shape of a roller whose longitudinal axis extends in the direction of the length LM and which also has a number of bristles, which laterally project beyond the bristle-carrying base body of the flat applicator. Of course, the scraper can also be used advantageously for non-cylindrical applicators.

A side view of the bristle-tipped end portion of such applicator 11 illustrates FIG Fig. 7 , It can be seen here how the flexures 12 are engaged with the bristle-carrying end portion, and understands that the great advantage of the triangular tongues is that they do not stress too much the laterally protruding portion of the bristle trim as the applicator is withdrawn. This is because the triangular tongues are not capable of folding or bending the bristles almost at right angles over a wide front. Instead, the triangular tongues each act as a sort of "flow divider" (term borrowed from the bridge of water bridges) so that the individual bristles will relatively quickly have the opportunity to slip in one of the gaps 10 and thereby pass the respective wiper lip without being overly stressed become. At the same time, the laterally projecting bristle stocking can thereby also be "combed out" and thus freed quite effectively with the required accuracy from an excessive loading of cosmetic mass, cf. again Fig. 7 ,

In the light of this function, it is clear why the scraper or the wiper lips should preferably not be made of a flexible material with rubber-like properties, but of a sufficiently flexible, yet dimensionally stable material - preferably from one of the same plastics, as they also Production of bristles molded onto a bristle carrier can be used.

At this point, we now have to talk about a particular aspect of the invention, which can be realized if needed with great advantage:
Its particular strength plays the scraper according to the invention - possibly even if its bending elements do not have the shape of triangular tongues - from where it is used together with an applicator whose bristle trim is accurate position, ie in which each bristle a known, in mass production reproducibly occupies the same foot position and ideally also always has the same, likewise reproducible orientation. If you then ensure that the scraper and the applicator always in a defined position (or at least in a defined position range) interact relatively, then you get a very effective applicator scraper system. Namely, at least the bristle positions of the individual, laterally projecting bristles of the bristle lining are then selected and matched to the design given to the lip portion of the wiper lip such that none of the bristles or at least substantially none of the bristles (viewed in the direction of the maximum length LM) in one Position is in which it meets exactly when pulling out on the free end face of a bending element 12 and on the tip of the triangular tongue, but instead is in the range of a gap 10 and therefore inserts easily when pulling the scraper in this. Bristles that insert in the course of pulling out of the applicator by the wiper in the column 10, the scraper a much less sharp curvature imposed as such bristles, by a continuous Wiper lip of a scraper not according to the invention when pulling out quasi "folded right angles". Properly used and tuned to the bristle of the applicator, the scraper according to the invention protects the bristle stock immensely and therefore also allows knickempfindlichere bristle designs. Even if only less knickempfindstliche bristle designs are used, the scraper according to the invention shows its strengths, because it is obvious that the forces to be overcome when pulling out of the applicator are the lower, the less sharp the bristles are bent when passing the wiper lip.

It is important to note that the applicator according to the invention in many cases also plays off its strengths at least to a significant extent if the positions of the individual bristles are not exactly matched to the scraper design in the manner described.

In order to ensure in the case of the described optimization for an always consistent or sufficiently tightly tolerated relative position between the applicator and scraper, the scraper body 2 is provided with guide members, which ensure the sufficiently accurate positioning of the applicator relative to the scraper. These governing bodies are in the Fig. 1 to 3 Good to see, they are executed here in the form of over the inner wall of the scraper body 2 raised guide rails 13. These guide members are preferably designed or arranged such that they unfold both a guiding action in the direction of the maximum usable length LM and in the direction of the maximum usable width BM. Alternatively, it would be conceivable that the inner wall of the scraper body as such, more or less full-surface can take over the leadership function. In a more or less full-surface clashing together on the other hand, the danger is great that it comes to an undesirable smearing / carryover of cosmetics on the applicator. Such a full-surface guidance is therefore only peripherally according to the invention, but it is not preferred.

At least one or two of said guide members 13 are preferably designed so that they lock with the applicator when it has reached its end position relative to the scraper. In this way, the applicator is securely held in its rest position.

The wiper lips are designed and arranged to abut or almost abut each other at their end facing the center of the passage, i. H. approach each other to a small distance of maximum 6/10 mm. Thus, the free tips of the triangular tongues of one wiper lip with the tips of the triangular tongues of the other wiper lip meet completely or almost, in o. G. Sense.

Of the 4 to 6 a second embodiment of the scraper according to the invention is shown. The statements made above for the first exemplary embodiment also apply in full to this second exemplary embodiment, with the following modifications: In addition to the bending elements 12 of the type described above, the wiper lips 4, 5 in this embodiment also have at least one, preferably a plurality of cuts 15, extending into the foot section 6 or 7 of the respective wiper lip or completely therethrough. The incisions are preferably configured such that the edges of the wiper lip bordering the respective incision do not touch but enclose a free space between them.

As far as a plurality of cuts 15 are provided on a wiper lip, the wiper lip is divided by these into a plurality of substantially independently mutually flexible tabs 16, each of which carries a plurality of the above-described bending elements 12. As a result, an even greater flexibility of the wiper lip is achieved. Optionally, as a result even after prolonged use not tending zusatzender with stripped cosmetic created path over which a better pressure balance can take place, so that when pulling out of the scraper no or only a slight negative pressure in the cosmetics container forms (pumping effect), which makes it difficult to pull out and in the worst case leads to an unwanted shipment of the cosmetic. Similar advantages then arise when reinserting the applicator through the scraper.

Otherwise, this embodiment differs from the first embodiment only in that here the angle W between the lip longitudinal axis LL and the longitudinal axis L of the passage is chosen to be smaller. For the angle W applies to this Exemplary embodiment W ≦ 85 ° or. ideally W ≤ 80 °. The angle should preferably not be less than 50 ° here, ideally even W ≥ 60 °.

Of the Fig. 7 to 9 a third embodiment of the scraper according to the invention is shown. The statements made above for the first and second embodiments also apply in their entirety to this third exemplary embodiment. The only difference between the second and third embodiments is that the angle W of the third embodiment corresponds to that of the first embodiment.

In a separate variant not according to the invention is a stripper for stripping a cosmetic applicator, which is designed exactly like the scrapers described above, but with the only difference that the two opposing wiper lips are not each subdivided into several bending elements, but are designed as a single continuous wiper lips. Because of this, all that has been said before applies equally to this wider scraper. Only the comments on the subdivision of each of the wiper lips in several bending elements do not apply to this scraper, otherwise the following description is also applicable to this scraper unchanged.

This variant not according to the invention may thus be, for example, a scraper designed as follows:
Scraper for stripping a cosmetics applicator when pulling out of its reservoir, wherein the scraper forms a substantially rectangular passage, which is blocked in the unloaded state by two opposing wiper lips. The wiper lips each have - at least substantially - the shape of a rectangle which is connected with one of its longer sides to the main body of the scraper and interacts with the other of its longer sides with the cosmetics applicator to strip it. Consequently, these wiper lips also essentially have the shape of a straight strip. Generally also applies to this variant that preferably only two such wiper lips are used and no further. Preferably, these scraper lips touch in the pulled-out state of the cosmetics applicator along a straight line of contact or include in the extended state of the cosmetic applicator between them a line-shaped gap having a width BS of not more than 1 mm and preferably not more than 0.6 mm.

It is also provided here that the wiper lips in the unloaded state in the direction of their longitudinal axes LS 1 and LS 2 have an at least substantially, preferably even up to tolerance-related deviations or due to the service life deformations completely rectilinear course. A substantially straight course may be mentioned if the mean radius of curvature of the longitudinal axes is less than 40 mm and preferably even less than 60 mm. Preferably, said longitudinal axes LS 1 and 2 extend parallel to the parting line T between the wiper lips.

Said longer sides of these wiper lips are preferably at least 10 mm, more preferably 15 mm and ideally even more than 20 mm long in the direction of the arrow P. Preferred embodiments even have wiper lips whose longer sides are at least 25 mm long.

In this case, the wiper lips preferably separate in the region of their narrow sides, ie in the region of their rear and front end, in each case one side gap S from the wiper base body 2, in this way that the wiper lips are actually connected to the wiper body 2 substantially only along its one longer side. In this way it is ensured that the wiper lips, even if they are not divided into individual segments, are sufficiently yielding.

In a direction transverse to the direction of said longer sides, the thickness of each wiper lip decreases toward those longer sides with which the wiper lip directly interacts with the cosmetic applicator. Because of this, each of the wiper lips has, in principle, the shape of a bending support tapering towards its free end, in this respect exactly as in the first embodiment.

This scraper is designed so that when it deforms in the course of passage of a cosmetic applicator essentially only those bending moments or bending stresses act that generate a bend around imaginary axes parallel to each other in space, so that the respective wiper lip as a wider, but behaves in the width direction of planar bending beam.
