Definitions

  • the invention relates to a scraper according to the preamble of the main claim.
  • the scraper must rest against the handle of the applicator with not insignificant pretension in order to be able to strip it off cleanly.
  • the scraper must not strip the bristle stock too hard, otherwise too little cosmetic mass remains in the bristle stock to allow an effective application that saves the user a multiple dipping the Kosametikapplikators in the cosmetics.
  • the bristles are heavily loaded, so they fatigue prematurely and then more or less bend. Such kinking occurs when the "bend recovery" modulus of the bristles is exhausted and, for that reason, they are unable to fully reattach the bristles after passing through the scraper.
  • such a behavior can be achieved by using either a soft or rubber-elastic wiper lip or at least a very thin-walled wiper lip.
  • a cosmetic wiper for stripping a cosmetic applicator with a tubular, a passage for the cosmetic applicator forming scraper body is proposed, which can be attached to a cosmetic reservoir.
  • the stripper body has a radially inwardly extending, in its undeflected state, the passage wholly or partially obstructing wiper lip.
  • This is characterized in that it comprises a plurality of wiper lip segments, which are designed in such a way that that the flanks of adjacent wiper lips overlap, seen in the circumferential direction.
  • the wiper lip is more extensible by the segmentation, as a wiper lip, which consists of a self-contained annular or cone-shaped plate or membrane.
  • the circumferentially successive wiper lip elements thus preferably form a circular, self-contained fan of overlapping "plates", each of which is rooted on its radially outer narrow side directly to the tubular stripper body.
  • the wiper lip segments each have two free main surfaces which, seen in the circumferential direction, each helically wind around the imaginary central longitudinal axis of the cosmetic wiper.
  • the main surfaces are those two surfaces which each have a much larger surface per se than each of the other free side surfaces delimiting the wiper lip segment. In any case, one can speak of a substantially larger surface area of a main surface if the relevant main surface is larger by at least a factor of 5, better still by at least a factor of 7.5, than each of the other free secondary surfaces.
  • Such a helical course also promotes the orderly repositioning of the bristles impinging on the wiper lip.
  • the bristles are not just “roughly” folded against the direction of movement of the applicator, but get at Moving at the same time also conveys a movement component acting in the circumferential direction, which protects the bristles. This is particularly important for applicators with injection-molded bristles, as they are more sensitive than bristles made of spun and drawn nylon filaments.
  • the major surfaces of the wiper lip segments are preferably oriented so that the major surfaces of the wiper lip segments span a surface that is approximately perpendicular to the longitudinal axis L of the wiper. This is the case when the local tangents of the major surface intersect the longitudinal axis at an angle not less than 60 °.
  • the overlapping wiper lip segments form a kind of shallow funnel that facilitates reintroduction of the applicator into the cosmetic reservoir and, on the other hand, improves the wiping action. It is ideal if the said angle is not less than 75 °.
  • the wall thickness of the wiper lip segments decreases from the radially outer end of the respective wiper lip toward the radially inner end of the wiper lip, preferably continuously and ideally by at least 20%. This positively influences the bending behavior.
  • the thinner radially inwardly projecting, thinner end of each Abstreiferlippensegments has increased flexibility.
  • the wall thickness of the scraper base body increases from its end facing away from the scraper lip to its end facing the scraper lip - preferably by at least 10%.
  • the stripper body has at its outer periphery a number of locking lugs for locking with the
  • the complete wiper lip from three or preferably four wiper lip segments. But it can also consist of five or six wiper lip segments. In this way, the wiper lip segments are supported at not too close intervals, so that they can play well their own flexibility. A larger number of wiper lip segments than six is not advisable.
  • a web in the sense of the invention is considered in any case a section into which the wiper lip segments pass by a bend.
  • a web is preferably understood to mean a section which in turn has two free main surfaces, each of which is substantially larger than its free auxiliary surface, preferably by at least the factor 5.
  • the two free main surfaces of the web are substantially perpendicular aligned with the immediately adjacent to him major surfaces of Abstreiferlippensegmente, which he connects with each other.
  • An orientation "substantially perpendicular to one another" is present when the main surfaces of the web are arranged at an angle of 90 ° +/- 25 ° relative to the main surfaces of the wiper lip segments. Ideal is an arrangement of 90 ° +/- 5 °. In this way, seen in the circumferential direction arises in the broadest sense "accordion-shaped" structure.
  • the wall thickness of the web perpendicular to the planes in which its major surfaces lie corresponds essentially to the wall thickness of the wiper lip segments which have these at their radially inner end, perpendicular to the plane in which one of their major surfaces lies.
  • the bridge unfolds its supporting effect so only by its geometry, but not by material accumulation.
  • the extent of the web in the direction parallel to the central longitudinal axis of the cosmetic wiper is at least twice and ideally even at least three times greater than its extent in the circumferential direction.
  • the web forms a relatively stiff, local support structure, which reliably prevents the eversion.
  • adjacent, overlapping wiper lip segments abut each other in the region of their overlap with their free main surfaces without being directly connected to one another.
  • the wiper lip segments thus support frictionally and positively against each other. This, too, can reliably prevent eversion if properly designed.
  • the length over which the free major surfaces of adjacent wiper lip segments overlap is greater by at least a factor of 2, more preferably at least a factor of 2.5, than the wall thickness of the wiper lip segments at their radially inner end.
  • the wiper body and its wiper lip formed from the wiper lip segments consist of one piece.
  • the production takes place by injection molding.
  • the wiper lip formed from the wiper lip segments from a different plastic, preferably from a soft or rubber-elastic plastic.
  • This other, second plastic will molded onto the prefabricated scraper body and thus welded in one piece with it.
  • the wiper lip is made of NBR, the advantages of the wiper according to the invention are particularly good effect:
  • the individual wiper lip segments are very flexible in itself, since "rubber-elastic". They can therefore be stretched very easily, so that the bristle stocking of the applicator can make its way under the emergence of only small forces.
  • the eversion is avoided, which is otherwise just a big problem when using NBR or other rubbery materials.
  • the wiper lip really consists of NBR and is vulcanized onto a scraper base body that predetermines its shape from another, non-rubber-elastic material.
  • the scraper according to the invention described above can make particularly good use of its advantages when it is used in a cosmetic unit comprising a cosmetic applicator with injection-molded bristles and a cosmetic storage container.
  • wiper lips each of which is so thin in itself that it alone can not resist eversion, the overlapping of the flanks in the circumferential direction of adjacent wiper lips being used to cause it to the wiper lips prevent each other from being everted.
  • the Fig. 1 shows a non-inventive, prior to the invention scraper.
  • the Fig. 2 shows a side view of a first embodiment of a scraper according to the invention.
  • the Fig. 3 shows a sectional view in the form of a central longitudinal section of Fig. 2 shown scraper.
  • the Fig. 4 shows the scraper gem. Fig. 2 in a view from below.
  • the Fig. 5 shows a section enlargement of the Fig. 3 .
  • the Fig. 6 shows a side view of a second embodiment of a scraper according to the invention.
  • the Fig. 7 shows a sectional view in the form of a central longitudinal section of Fig. 6 shown scraper.
  • the Fig. 8 shows the scraper gem. Fig. 6 in a view from below.
  • the Fig. 9 shows a section enlargement of the Fig. 7 .
  • Fig. 10 shows sketchy and exaggerated clearly illustrated the accordion-like behavior under load, which the webs preferably show when expanding the wiper lip.
  • FIG. 1 a construction that was at the beginning of the internal development, but which is not according to the invention.
  • the said FIG. 1 shows a Kosmetikabstreifer, which consists of a tubular stripper body and a scraper lip integrally attached thereto.
  • the wiper lip is seen in the circumferential direction (ie along the arrow U) closed in itself.
  • the wiper lip is formed comparatively thin-walled. It has, again in the circumferential direction, an undulating form. In this way and This prevents the thin-walled wiper lip from being turned upwards or inwardly under the influence of forces which act in the direction of the arrow P1.
  • FIGS. 2 to 5 show a first embodiment of the invention.
  • the cosmetic scraper 1 consists of a scraper body 2, which carries a wiper lip 3.
  • the stripper body 3 is preferably provided at its first end facing away from the wiper lip with a collar 4, with which it rests against the end face of a container neck, not shown.
  • the stripper body 3 in the present case has the shape of a circular tube that forms a passage 5 in its interior, through which a bristled busy applicator can be pulled out of the cosmetic reservoir to the outside.
  • the wiper body may also have a polygonal cross-section, without prejudice to the fact that a circular cross-section is preferred because it avoids an inhomomene wiping result.
  • the wall thickness of the applicator body takes in the direction of his wiper lip end facing away from his wiper lip facing the end - apart from the only local diameter increase by the collar 4.
  • the wiper body 2 In the region of its second end or directly at its second end, the wiper body 2 is equipped with a wiper lip 3.
  • the scraper body 2 In the present case, the scraper body 2 is in one piece and preferably also einstofflich in the wiper lip 3 over.
  • the wiper lip 3 obstructs the passage 5 partially, as the best of the FIG. 4 can be seen. In the middle of the wiper lip 3 leaves an unobstructed space 6 free. Of the maximum diameter Dmax of this clearance is slightly smaller than the maximum diameter of the applicator handle, not shown, which connects the bristle trim to the closure cap of the cosmetic reservoir, which serves as a handle.
  • the special feature of this cosmetic scraper is the special design of its wiper lip 3.
  • the wiper lip 3 is divided into a plurality of wiper lip segments 7.
  • Each of the Abstreiferlippensegmente 7 has the shape of a circular ring portion which is connected at its outer periphery directly integrally to the Abstreifer stresses 2 and beyond in the circumferential direction has two free side flanks 8, and a free inner circumference 9, see.
  • Fig. 4
  • Each wiper lip segment 7 has a plate-like shape, i. it has two free major surfaces 10, each having a much larger surface area than any one of the other free surfaces adjacent the wiper lip segment.
  • the special feature of the wiper lip segments 7 according to the invention is that their main surfaces 10 run helically in the circumferential direction. In this way, it is possible that in each case two circumferentially adjacent Abstreiferlippensegmente overlap at their free side edges 8 scaly, since their free edges 8 seen in the direction of the longitudinal axis L come to lie one behind the other. As a rule, this overlap results in the wiper lip segments 7 remaining in their undeflected state, i. H. if no cosmetic applicator is used, touch on its main surfaces.
  • the wiper lip segments 7 each have the shape of a circle segment in their projection along the longitudinal axis L, cf. Fig. 4 and 8th ,
  • the main surfaces 10 in the radial direction at the same time include an acute angle ⁇ with the longitudinal axis of the scraper.
  • the characteristic produced by the wiper lip segments depends on how much two adjacent wiper lip segments overlap and can be adjusted by the designer depending on the wall thickness of the wiper lip segments. A favorable result is usually achieved when the length for OVL on which the wiper lip segments overlap and the wall thickness W of the wiper lip elements at their radially inner end are: 2W ⁇ OVL ⁇ 3W.
  • FIGS. 6 to 10 illustrate a second embodiment of the invention.
  • This second embodiment corresponds over long distances to the first, previously described embodiment, so that what is said for this second embodiment applies mutatis mutandis - unless otherwise explicitly described below differences, which has the second embodiment over the first embodiment, something else.
  • the wiper lip segments of the second embodiment are configured the same as those of the first embodiment. They also overlap, but less so, like those of the first embodiment. For this purpose, they are connected to one another in the region in which they overlap with a web 13, so that the overlapping wiper lip segments are not positively or frictionally supported against one another but are firmly bonded.
  • a web 13 so that the overlapping wiper lip segments are not positively or frictionally supported against one another but are firmly bonded.
  • the wall thickness WS of the web substantially corresponds to the wall thickness W of the two overlapping wiper lip segments at their radially inner end. It is also clearly visible that the extent LS of the web in the direction parallel to the longitudinal axis L of the applicator is at least three times greater than the wall thickness WS of the web.
  • the major surfaces 14 of the ridge are substantially perpendicular to the major surfaces 10 of the scraper lip segments joined by the ridge and that the major surfaces 14 of the ridge transiently merge into the major surfaces of the wiper lip segments.
  • the webs each allow a certain "Zieharmonika effect", because they are sufficiently elastic, at least in the region of its radially innermost end - under the influence of the force applied by the wiper sliding through the wiper applicator forces - something transverse and thus the expansion of the To facilitate a scraper on its inner circumference, cf. Fig. 10 ,
  • the wiper lip is circumferentially closed in itself and in the circumferential direction has a accordion-like structure of plate-shaped Abstreiferlippensegmenten and connecting webs, the main surfaces of Abstreiferlippensegmente and the webs substantially perpendicular aligned with each other.
