Definitions
- the invention is directed to methods for producing such a scraper.
- the invention is directed to cosmetic unit with a cosmetic reservoir, an applicator, a cap and a mounted in the neck or in the removal opening of the cosmetic reservoir wiper for stripping of cosmetic mass from the applicator.
- a cosmetic unit comprising a cosmetic storage container, an applicator, a closure cap and a scraper (1) mounted in the neck or in the removal opening of the cosmetic storage container for stripping the cosmetic mass from the applicator, wherein the scraper (1) according to one of claims 1 - 11 is formed and / or produced by one of the method according to claim 12 or 13.
- the scraper has a first component usually in the form of a holding portion for fixing the scraper to a cosmetic reservoir.
- the scraper on at least two stripping acting Abstreiferarme.
- At least one of the wiper arms is pivotally mounted relative to the wiper by means of at least one hinge on the first component of the wiper or the holding portion of the wiper.
- a scraper component shown in FIG. 7 in the form of a bending beam or projection 10 ⁇ without a local thin point which deforms uniformly or largely evenly (+/- 25%) along the entire length with the radius RK has no hinge or is not with the help attached to an integral hinge.
- a hinge in the context of the invention, in particular an integral hinge, in the broadest sense are spoken, if there is an area that applies the major part of the deformation, which contributes to the fact that the hinged wiper arm or a projection moves outward under the influence of the intended forces occurring during the application.
- FIG. 8 shows that the major part of the deformation which leads to the displacement of the scraper arm carrying a projection in the radially outward direction is applied by the thin spot which is clearly visible.
- such a region under the influence of the bend shows a local radius of curvature which is at least a factor of 5 smaller than the radius of curvature of the immediately adjacent scraper wall regions, which may also be deformed under load, in each case with respect to an axis perpendicular to the longitudinal axis L.
- the at least hinge is a local thin spot. Viewed in the direction of the longitudinal axis close as on both sides of the thin spot by at least the factor 3 thicker wall sections of the scraper.
- the invention is characterized in an embodiment therefore characterized in that the at least one hinge is formed in the form of a local thin point.
- each of the wiper arms is articulated to the holding section with only a single hinge, wherein the hinge is preferably arranged centrally relative to the extension of the wiper arm in the circumferential direction on the wiper arm.
- a single and preferably centrally positioned hinge does not oppose the desired outward pivoting of the scraper arm, even if the scraper arm has a not insignificant curvature in the circumferential direction and the associated flexural stiffness.
- this spring element can functionally be a further component of the hinge, so that the spring element will be less resilient than, in particular, together with the actual hinge, will define the pivot axis.
- this spring element has an independent, independent of the hinge function, namely a
- the at least one spring element is an elastic strip which, relative to the wiper longitudinal axis and toward the distal end of the wiper, respectively before the at least one hinge, preferably all hinges, on the holding portion and after the respective Hinge is connected to the scraper arm. It has proved to be advantageous if the spring element has a preferably constant curvature whose center of curvature lies between it and the wiper longitudinal axis.
- each Abstreiferarm seen in the circumferential direction centrally located hinge and two seen in the circumferential direction on both sides next to the hinge arranged spring elements is therefore further characterized in that arranged on one, preferably on each, Abstreiferarm viewed in the circumferential direction centrally located hinge and seen in the circumferential direction on both sides next to the respective hinge in each case a spring element is arranged.
- the or the scrapers are designed so that his / her hinges and preferably also the optionally associated spring elements allow at least one and preferably all Abstreiferarme to pivot about the above axis by an angle of at least 90 ° relative to the longitudinal axis. This is an angle of exactly 90 ° or possibly with a tolerance of +/- 15 °. Accordingly, the invention finally also provides that at least one, preferably all, wiper arms are designed to be foldable outwards at an angle of at least 90 ° relative to the longitudinal axis.
- the scraper arms integrally formed on a holding section can be designed differently.
- a variant of a Abstreiferarms may have its lower edge a ring portion.
- Particularly suitable manufacturing methods for a scraper according to the invention are the injection molding of plastic and plastic processing 3-D printing or rapid prototyping method.
- the invention therefore also provides in a further embodiment that the scraper is produced by means of injection molding or by means of a 3-D printing process.
- a method is suitable for injection molding a scraper, which consists of at least two sections which are connected to each other by means of an integral hinge, wherein the sections are injected in an unfolded position, which does not correspond to the position they are during use of the intended use of the finished scraper relative to each other and that the sections after forming the scraper by itself or with the help of external forces relative to each other pivot in the position they occupy unloaded when used as intended of the finished scraper relative to each other.
- a method of injection molding a scraper which consists of at least two sections, which are connected to each other by means of an integral hinge, in which the sections are injected in a position that finished their position Applicator when used properly, wherein the hinges are used to move the hinged portion when molding from the injection mold relative to the other portion and so facilitate the molding or allow.
- the scraper injection molding technology in an embodiment in which its individual components already occupy each other at least approximately their use positions to each other.
- the invention provides an alternative manufacturing method.
- Fig. 1 shows a first embodiment of the scraper according to the invention in perspective seen from the side, in multiple magnification.
- FIG. 2 shows the wiper gem.
- Fig. 1 in a pure side view.
- FIG. 3 shows the scraper according to FIG. 1 in frontal view, seen in the direction of the central longitudinal axis, from above.
- Fig. 5 shows a central longitudinal section of the scraper gem. Fig. 1.
- Fig. 8 illustrates what falls under the concept of hinge.
- distal refers to the longitudinal direction furthest into the interior of a Kosmetikvorrats disposers protruding side of the scraper
- proximal refers to the side of the scraper, in the longitudinal direction of the edge of the removal opening of the scraper Cosmetic container or cosmetic reservoir is closest.
- the second stripping arms 3a each have a second handle portion 4a. While in each case a ring portion 5 is integrally formed on the first stem sections 4, such is missing at the second stem portions 4a.
- the second handle sections 4a of the second wiper arms 3a each fit into a respective window 9a extending between two first handle sections 4 of the first wiper arms 3 and above a ring arm 8 of the ring sections 5.
- the holding section 2 generally has a substantially (to tolerances) cylindrical shape and is usually completely closed in the circumferential direction.
- the holding section 2 defines with its center or its center the central AbstreiferlFigsachse L.
- Fig. 1 provides the best overview of these hinges 12, while the details of the hinges can best be seen with reference to Figs. Clear over all other types of hinges preferred is the integral design of the hinge, as shown in FIG. 5. In this case, the design is preferably selected as a film hinge.
- 3a protrude at least approximately at right angles with respect to the longitudinal axis L from the holding portion 2 of the scraper 1, sprayed, then accounts for the undercuts in the shape of the incisions E and the window 9a, 9b and it suffices an injection mold which usually only in a plane across or must be divided perpendicular to the longitudinal axis L. This is shown for a second Abstreiferarm 3a with projection 10th
- each of the stem portions 4, 4a preferably has a width which extends over at least 10%, better over at least 15% of the circumference of the holding portion 2, where it merges into the stem portions 4, 4a.
- each stem portion 4, 4a tapers from where it is connected to the holding portion 2, towards its distal end, at the first stem portions 4, towards its respective ring portion 5 - in the sense that it becomes narrower in the circumferential direction.
- the taper is, however, preferably designed only with restraint and is ideally from the proximal end connected to the holding section 2 to the distal end of less than 20%, better than 15%, since this is the only way to avoid that the proximal region of the stem section 4, 4a too rigid and / or the distal region becomes too yielding, so it lacks the necessary uniformity of bending elasticity.
- each of the stem portions 4, 4a is slightly curved, usually so that the longitudinal axis L remote from the outer surface of the stem portion 4, 4a is convexly curved in the circumferential direction and optionally the longitudinal axis L facing inner surface of the stem portion 4, 4a is also concavely curved in the circumferential direction ,
- the stem portions 4, 4a are not twisted with respect to the longitudinal axis L, in the sense that they wind around the longitudinal axis L in the manner of a helix.
- each of the first handle sections 4 merges into its annular section 5.
- each first stem portion 4 and the annular portion 5 formed thereon is usually designed to correspond to the forearm support of a crutch extending upwardly away from the handle.
- Each of the first and second handle sections 4, 4a is usually hinged so that it can move more than insignificantly in radially outward direction.
- the distal end of each stem section 4, 4a in particular where the transition takes place in ring section 5, under the intended forces during stripping forces by more than 0.8 mm and better still by more than 1.2 mm in the radial direction shift elastically reversible outwards.
- the ring arms 8 and the remainder of a respectively associated ring section 5 and preferably also the outer surface of the stem sections 4 have an identical curvature in the circumferential direction.
- the ring arms 8 are also designed to be extremely narrow in the direction parallel to the longitudinal axis L, their maximum extent DR in this direction is preferably 3.5 mm, better still only 2.5 mm, cf. Fig. 5. Since the scraper 1 is usually made of an elastic plastic, the ring arms 8 have due to its ability to move under the intended purpose of stripping during loading more than insignificant relative to the stem portion 4 in the radial direction outward. By an insignificant shift is meant that displacement which is inherently unavoidable by virtue of the inherent elasticity of each body. In any case, a displacement of at least 0.8 mm, more preferably at least 1.5 mm, is understood to mean a displacement that is more than insubstantial. Well with reference to FIG. 1 it can be seen that of two adjacent ring sections 5, the associated
- a window 9 a, 9 b is bounded, which connects the scraper 1 otherwise circumferentially enclosed inside with the space on the peripheral outer side. Such a window prevents the otherwise dreaded "blobb effect".
- the second Abstreiferarm 3a along its entire extent in the direction of the longitudinal axis of a circumferentially constant or at least in Substantially constant width (+/- 7.5%) ⁇
- the hinge attachment of the second Abstreiferarms 3a having the projection 10 on the holding section 2 by means of a hinge 12 helps that the protrusion 10 having the second Abstreiferarm 3a under the influence of the intended forces occurring during application forces more than slightly insignificant reversible-flexible can shift in radially outward direction.
- "more than negligible" means a displacement of the free, distal end of the projection by at least 0.7 mm, better still by at least 1 mm.
- the second wiper arm 3a having the projection 10 does not completely cover the free surface of the window 9a, 9b. As you see well with reference to FIG. 1, at least 45%, better even at least 55% of the imaginary window area remain really free.
- the second wiper arm 3a has the task of acting as an "auxiliary wiper" for the applicator handle, in turn wiping off that narrow portion of the handle which otherwise passes through the nip between two immediately adjacent annular arms 8 without being stripped off, ie from 1, which illustrates this, so that the second wiper arm 3a ensures that the entire circumference of the handle is wiped off.
- the second scraper arm 3a terminates, viewed in the direction of the longitudinal axis L, in a viewing direction aligned with the distal end above the annular sections 5 of the first scraper arms 3
- the holding portion 2 will have a stop collar 6, with which it rests in the fully assembled state against the end face of a container opening.
- the holding section 2 has a latching element which allows its positive fixing in the interior of the container opening, where a complementary latching element is found.
- the locking member is designed as a locking bead 7.
- the scraper 1 seen in the direction of its longitudinal axis L, divided into two sections.
- the first section of the scraper 1 forms the said holding section 2.
- the second section of the scraper consists of the first or second scraper arms 3, 3a.
- the first and the second section preferably have the same or approximately the same length in the direction of the longitudinal axis L up to 30% difference.
- the second section of the scraper 1 is preferably conical or inclined, as shown in FIG. A cone angle of 7.5 ° to 15 ° relative to the scraper longitudinal axis L is particularly useful, cf. Fig. 6.
- the holding section 2 merges into preferably at least two first handle sections 4 and two second handle sections 4a, which project from it in the direction substantially parallel to the longitudinal axis L in the manner of cantilevered beams.
- a narrow gap remains free, which increases in the ideal case in the vicinity of the retaining ring 2, where only the two stem sections 4 are immediately adjacent.
- a window 9 remains free, the shape of which one can preferably describe as "shape of the number 6" and / or "shape of a mirror-inverted digit 6".
- the longest and the shortest stem section 4 differ in their length in the direction parallel to the longitudinal axis L by about 50%, preferably by 50% +/- 5%.
