EP2583584A2 - Multiple stripper - Google Patents

Abstract

The stripper (1) has a holding section (2) for fixing the stripper to a cosmetics storage container, and stripping units (3, 4) arranged one behind the other in an effective direction. One of the stripping units is arranged at the holding section or at another stripping unit such that the former stripping unit communicates with an area storing the cosmetics on a front side and on a rear side. The stripping units are designed as disks that are arranged perpendicular to a stripper longitudinal axis (L), where segments of the stripping units form a bumper bracket.

Description

The invention relates to a scraper according to the preamble of claim 1. Such scrapers are in various forms in use to strip cosmetic applicators, which, as long as they are unused, dive into a cosmetic stock, from which they are pulled out to make the applicator ready for use.

A recurring problem is caused by the fact that an applicator heavily loaded with cosmetic mass prevents air from flowing into the reservoir during extraction of the applicator from the cosmetic reservoir, since the cosmetic applicator and its charge seal almost airtight against the wiper lip. As a result, a negative pressure builds up in the cosmetic reservoir, which collapses abruptly as soon as the distal, ie the handle remote from the end of the applicator has passed the wiper lip. The sudden collapse of the negative pressure leads to a loud noise that can be described as a "pop". This noise is often perceived as a contradiction to a high-quality visual and haptic presentation of the cosmetic unit. Even more disturbing is the fact that the sudden pressure equalization often leads to the fact that clearly perceptible drops of the cosmetic from the near-open area of the cosmetics reservoir squirt out or the distal end of the applicator is overloaded with mascara and prevent a clean application.

In order to remedy this, various solutions have been proposed in the past. These solutions tend to all go in the same direction - there are smaller gaps or openings in a lateral area of the scraper and / or interruptions in the wiper lip itself created, which form a kind of "bypass", which ensures that air continuously flow into the cosmetics reservoir can, so that no or only a lower negative pressure builds up. The problem, however, is that it is difficult to ensure that the smaller gaps, openings or interruptions over time are not really clogged by cosmetics that settle in front of or behind the scraper as a result of multiple withdrawals and reinsertion of the seldom completely discharged cosmetic applicator possibly there dries.

In view of this, the invention is based on the object to provide a scraper or provided with a scraper cosmetic unit that permanently shows a reduced tendency to noise and / or spatter when pulling out of the applicator or frees the applicator at the distal end of excess cosmetic ,

The solution of this object is achieved by the features of claim 1.

Accordingly, a scraper for stripping a cosmetic applicator with a preferably tubular holding portion for setting the scraper to a cosmetic reservoir is proposed, the more in the direction of action - ie regularly in the removal direction of the cosmetic applicator - arranged in succession Abstreiforgane, of which at least one Abstreiforgan is held on the holding portion or the adjacent Abstreiforgan that it communicates both on its front and on its back unhindered with the space-storing the cosmetic. Such unimpeded communication is in any case if, directly next to the wiper member, preferably by the shortest possible route, there is a direct connection between the front side of the wiper member (seen in the withdrawal direction) and the rear side of the wiper member. In this case, the clear cross-section of the connection is so great that even in the course of the period of intended use of the cosmetic unit in question, no complete clogging of the compound is to be feared. Such a shortest possible connection is z. B. given when the wiper member in question is a disc-shaped body and immediately along the peripheral edge of the disc-shaped body, a connection between its front and back is created.

Another variant of the scraper according to the invention which is preferably used to solve the problem of the invention provides a scraper for stripping off a cosmetic applicator with a preferably tubular holding section for fixing the scraper to a cosmetic storage container. In this case, this has the scraper a plurality of successively arranged in the direction of action Abstreiforgane, of which at least one wiper member is held only by means of several columns on the holding portion or the adjacent wiper member. As a result, large "windows" can be realized laterally in the after-region of the optionally also funnel-shaped wiper element, which bring about the desired effect according to the invention or make it feed.

In the context of a preferred embodiment, it is provided that at least one wiper member of the wiper, more preferably at least two wiper members of the wiper, is or are designed as a disk arranged substantially perpendicular to the wiper longitudinal axis L. In any case, a disk in this sense is considered to be a structure whose extent in the direction parallel to the longitudinal axis is not more than 5.5 times better than not more than 3 times the maximum wall thickness in the direction parallel to the wall thickness.

It is preferred that the single-pocket main surface be substantially conical to one or more of said discs.

In the context of a preferred embodiment, it is provided that at least one wiper of the wiper, preferably at least two wipers of the wiper have a number of slots which divide the respective wiper member into several segments, wherein the segments are preferably formed in the manner of cake pieces whose tips are in the middle of each other or meet and abut each other with their flanks or only separated by a small gap. In any case, a gap is small in the sense of this development if its maximum width is not more than 1 mm and preferably not more than 0.5 mm.

Preferably, at least one wiper of the wiper, better have at least two wiper of the scraper on a central opening, which is always unlocked, as long as no cosmetic applicator protrudes through the wiper member in question.

Preferably, the segments of the segmented wiper member are designed such that they cantilevered bending beams form, which bend resiliently when pulling out of the cosmetic applicator in the direction of the tensile force, wherein the bending force counteracting the spring is so large that the segments already snap back into their undeflected position, when the cosmetic applicator in the course of its extraction, the relevant wiper predominantly but has not completely happened yet.

It is ideally so that the thickness of a cantilevered bending beam forming segments decreases in each case in the direction of its clamping point towards its free end. This ensures that the centrally located region of each bending beam does not exert too great a pressure effect on the bristle lining or the stripper area passing in its place and thus nowhere unfolds an excessive stripping effect.

Preferably, it is such that the holding portion forms a further wiper member. This is best done by forming a tubular body that tapers at its unevenness end such that the taper forms a circular wiper lip, ideally completely closed in the circumferential direction. With such an additional scraper can be ensured that the stem of the applicator is optimally stripped. In the case of correct dimensioning, which is preferably to be provided, stripping of the stem takes place without an excessive stripping effect being exerted in the region of the bristle lining by this stripping member, the stripping member of which is at least predominantly responsible for its proper stripping.

Preferably, the tubular body is completely closed at its periphery and thus forms a Abstreifervorhof, which substantially and preferably exclusively on the Wiper opening bordered by the wiper lip communicates with the space storing the cosmetic.

Within the scope of a preferred solution which is completely alternative to the previous proposals, it is provided that the scraper has a plurality of scraper elements arranged one behind the other in the direction of action, one of these scraper elements being arranged as wholly or substantially perpendicular to the scraper longitudinal axis, preferably slotted and ideally in accordance with one of the preceding claims Claims designed disk is formed and another of the Abstreiforgane is formed by a tubular body which tapers at its container-like end such that the taper forms a circular, ideally in the circumferential direction completely self-contained wiper lip.

A development of the inventions provides that the slots are partially or preferably all not rectilinear, but preferably designed so that they form an S-shaped course.

It is preferably claimed additional protection for a system of a cosmetic reservoir and a scraper fixed thereto according to one of the other claims, wherein at least one scraper freely projects into the interior of the cosmetic reservoir, without being in direct contact with the or the walls of the cosmetic reservoir, wherein the system preferably also comprises a cosmetic applicator.

Preferably, such a system is designed so that the said wiper member at least 1 mm better than 3 mm minimum distance to the or the walls of the Kosmetikvorratsbehälters complies.

Protection is also claimed for the combination of individual features of one of the subclaims with the main claim.

Further advantages, effects and design possibilities of the inventions will become apparent from the following description of three embodiments with reference to the figures listed below.

The FIG. 1 shows a side view of a first embodiment of the scraper according to the invention, installed in the neck of a bottle, which serves as a cosmetic reservoir.

The FIG. 2 shows a perspective side view of the first embodiment of the scraper according to the invention.

The FIG. 3 shows a perspective side view of the first embodiment of the scraper according to the invention in a section along the Abstreiferlängsachse L.

The FIG. 4 shows a plan view of the container uninterrupted scraper of the scraper, which represents the first embodiment here.

The FIG. 5 shows a side view of a second embodiment of the scraper according to the invention.

The FIG. 6 shows a perspective side view of the second embodiment of the scraper according to the invention.

The FIG. 7 shows a perspective side view of the second embodiment of the scraper according to the invention in a section along the Abstreiferlängsachse L.

The FIG. 8 shows a plan view of the container uninterrupted scraper of the scraper, which is the second embodiment here.

The FIGS. 9 to 12 show a third embodiment of the invention.

How to get along well with the FIG. 1 recognizes the scraper 1 of the first embodiment consists of a holding section 2 and two Abstreiforganen 3 and 4.

The holding section 2 is here, as it is preferred, formed as a circumferentially completely self-contained tubular body, by means of which the scraper 1 is fixed in the neck of the bottle 13, which serves as a cosmetic reservoir. For this purpose, the holding portion 2 is preferably provided with a collar-like stopper 14 which abuts against an end face of the bottle neck and so limits the way by which the scraper 1 can be inserted into the neck of the bottle and at the same time acts as a seal so as to cause leakage To prevent cosmetics from the container. As you can see, the holding section 2 is additionally equipped with at least one locking member 15 which is locked with a corresponding locking member or a corresponding surface of the bottle neck. The outer diameter of the holding portion 2 is usually adapted to the inner diameter of the neck provided for receiving his neck, so as to ensure a play-free fit of the scraper 1 in the radial direction. In this embodiment, the holding portion 2 has a substantially constant inner diameter, that is, the holding portion 2 does not contribute as such to a substantial extent to the stripping effect. At its safe monotone end of the holding section 2 goes into several Columns 7 over. By means of these columns 7, a wiper member 3 is fixed to the holding portion 2.

The wiper 3 is formed here as a disc, which is preferably circular. A disc in the sense of the invention is a structure having two major major surfaces and a comparatively small circumferential surface. The two major major surfaces are arranged so that they are substantially perpendicular to the Abstreiferlängsachse L.

Preferably, this disc is slightly tapered, d. H. at least one of its two major major surfaces, but preferably both major major surfaces are not one hundred percent oriented perpendicular to Abstreiferlängsachse L, but instead instead preferably extend at an angle of 90 ° +/- max. 15 ° and ideally at an angle of 90 ° +/- max. 10 ° to the Abstreiferlängsachse L. Ideally, the two major major surfaces are tapered so that they are slightly inclined in the direction of the center of the disc in the unrendered direction. This facilitates the reintroduction of the applicator.

The disk is preferably between 0.5 and 1.75 mm thick in the direction parallel to the longitudinal axis, although this area does not have to be fully utilized, despite the thickness of the disk decreasing towards the center. It is provided with a number of slots extending from the center of the disc to the disc rim. In the case of the Fig. 1 to 4 In the preferred embodiment shown, two slots which are directly opposite one another in the center region always form an S-shaped slot arrangement, as a result of which, surprisingly, an improved wiping action is produced in comparison to exclusively straight slots. Due to the straight or S-shaped slots, the vast majority of the major major areas is divided into one-sided clamped bending beams, the have a cake-like, triangular shape and are arranged like the pieces of a cake in a circle. The acute angle of each bending beam on its center-facing side is preferably in a range for which 42 ° ≦ β ≦ 28 °. Such designed tips "comb" the applicator very effectively and therefore cause especially in bristled applicators a very good wiping result.

How best to hand on the Fig. 3 sees, it is preferably such that the thickness of the disc decreases from its outer periphery toward the center of the disc, which positively influences the deformation behavior of the wiper member or its bending beam. The bending beams bend elastically when pulling out the cosmetics applicator. In this case, the bending force counteracting the bending spring is preferably so large that the segments already snap back into their undeflected position substantially when the cosmetic applicator predominantly but not yet completely has passed the relevant wiping element in the course of its extraction. As a result, in particular the applicator handle remote from the free end of the applicator is very effectively stripped off.

Preferably, the slots terminate on the outside of an imaginary circle having a radius which is about% of the maximum disk radius, so that the disk still has the required inherent stability despite the slots and not permanently "overturned" when the applicator is pulled through it. The disc is punched in its center. In this case, the hole diameter, which has the container interior facing disc, preferably larger (ideally by at least 20%, better by at least 30%) than the hole diameter, which has the container opening facing disc, which is equal to come to speak ,

As already stated above, the wiper 3 is held by means of several columns 7 on the holding portion 2 in position. These columns 7 are each preferably rectangular bars, ie structures whose length is substantially greater parallel to the longitudinal axis L of the scraper 1 than their width in the circumferential direction. Preferably, the bars are each so slender that their extent RE in the circumferential direction is at most 7.5% and preferably at most 5% of the circumference along which the bars are set up. In individual cases, the bars can be wider and each make up a maximum of 10% of the circumference, but such an embodiment is not preferred, but in fact only the exception for which only secondary protection is claimed. Ideally, the number of a wiper 3 holding rods is limited, so that a maximum of 4 such rods are provided for a wiper member 3. In individual cases, up to 6 such rods may be provided for a wiper 3, but then each rod should normally have an extension RE, which makes up a maximum of 5% of the circumference and better makes up a maximum of 3% of the circumference. As a rule, the columns are evenly distributed along the circumference.

It is noteworthy that the columns are preferably designed such that they have a thickness in the radial direction which is greater than the wall thickness of the holding section 2 measured in the radial direction Fig. 4 illustrates this quite well, because it shows that the columns protrude in this embodiment, the inside over the inner surface of the holding portion 2.

How best to use the FIG. 1 sees large side "window surfaces" are created in this way, over which the wiper organ can communicate freely with the space of the reservoir storing the cosmetic - which means nothing else than that when pulling out of the cosmetic applicator by the wiper through no noticeable pressure difference between the front and the back of the scraper element can form. This is ensured even if at the edges of the wiper 3 larger amounts of stripped cosmetic have accumulated. Because the "window surfaces" are so large that the accumulating by stripping at the edges of the wiper 3 cosmetic mass drips back into the pantry or falls back before the window surfaces are clogged by this. This makes it possible for the wiper in question, in particular from the tip of the applicator to remove a larger amount of excess cosmetic, without it being undesirable for application and acoustic reasons, because a spraying favoring and unattractive-sounding "popping effect" comes through Pressure differences between the front and the back of a Abstreiforgans comes about.

The hitherto described for the wiper 3 applies to the deviations described below in detail for the wiper 4 and preferably also for each further disc-shaped wiper member, as far as such is provided in the individual case - two successively discrete, disc-shaped wiper members for the majority of cases the optimum are and therefore prefer to claim protection.

Also, the wiper 4 is formed as a disc, as described above for the wiper member 3. The wiper 4 is also held by means of several columns to the preceding wiper 3. Because of this, the wiper 4 can communicate freely with the space of the reservoir storing the cosmetic. The preferably only difference to the wiper 3 is the, that the hole diameter, which has the central hole of this disc-shaped wiper member smaller than that of the disc-shaped wiper member 3. Not least because of this, the wiper 4 is still able to strip a certain portion of the cosmetic from the applicator, which had first passed the wiper member 3, without being stripped.

The FIGS. 5 to 8 show a second embodiment of the invention. This second embodiment of the invention is designed substantially the same as the first embodiment of the invention. Because of this, what has been said for the first exemplary embodiment of the invention applies in the same way, unless something different results from the differences described below.

The second embodiment differs from the first embodiment in three aspects:

The disc-shaped wiper members in this embodiment have a constant thickness parallel to the direction of the longitudinal axis L.

In addition, the disc-shaped wiper members are completely flat in this embodiment, d. H. they are not conical, but their two major major surfaces are each oriented orthogonal to the longitudinal axis L.

Moreover, in this embodiment, the holding portion 2 is shaped to taper toward the container inner side and form a circumferentially self-contained circular wiper lip. For this purpose, the holding portion 2 is formed conically at its container inside end. Preferably, it is such that these circular Wiper lip at the inner end of the tapered portion in particular has the purpose to strip the stem of the applicator and to free as much as possible of adhering there cosmetic. Accordingly, this wiper lip is dimensioned. In this case, the circular applicator or the holding section 2 preferably has no bypass opening, ie no path which bypasses the wiper lip, in order to track air into the cosmetic storage container.

Instead, this circular wiper lip is instead dimensioned so that it has a larger clear diameter than comparable wiper lips, which not only have the task of wiping off the applicator handle, but also the actual applicator body or the bristle facing of the applicator. The size of the clear diameter is selected according to the invention so that the circular wiper lip strikes substantially only the applicator stem and unfolds no significant wiping action relative to the actual applicator body or the bristle border of the applicator. The latter is the case when the circular wiper lip holds so much distance to the core of the applicator, to which the bristles are attached, that sufficient air can flow into the cosmetic storage container through the already stripped bristle stock in order to remove the disturbing "plop" and / or or to substantially avoid the spraying occurring in the course of this or the increased deposition of cosmetic on the applicator tip.

In this exemplary embodiment, the applicator handle is preferably dimensioned so that it still protrudes through the circular wiper lip when the applicator is pushed completely into its stowed position, whereby the cosmetic storage container is completely sealed, so that the stocking cosmetic does not pass the wiper can, for example, if the cosmetic unit is stored in the head stand at higher temperatures, which can occur involuntarily in a handbag.

The FIGS. 9 to 12 show a third embodiment of the invention. The embodiment is designed such that the two disc-shaped wiper members are designed to be 100% as in the first embodiment, while the associated holding portion forms an additional wiper member, as in the second embodiment.

Regardless of the subject matter claimed by the claims separately set forth, protection is also claimed for a scraper having the following features:

Scraper 1 for stripping a cosmetic applicator, wherein the scraper 1 has a plurality of scraper elements 3, 4, 5 arranged one behind the other in the direction of action, one of these scraper elements being arranged as slotted and preferably ideally in accordance with the possibilities described in this application, arranged substantially perpendicular to the scraper longitudinal axis L. Washer is formed and another of the wiper members is formed by a tubular body, which tapers at its Behäleinereinwärtigen end such that the taper forms a circular, ideally in the circumferential direction completely self-contained wiper lip 11.

• Abstreifer 1 zum Abstreifen eines Kosmetikapplikators mit einem Halteabschnitt 2 zum Festsetzen des Abstreifers 1 an einem Kosmetikvorratsbehälter 6, dadurch gekennzeichnet, dass der Abstreifer 1 mehrere in Wirkrichtung hintereinander angeordnete Abstreiforgane 3, 4, 5 aufweist, von denen mindestens ein Abstreiforgan nur mittels mehrerer Säulen 7 an dem Halteabschnitt 2 oder an dem benachbarten Abstreiforgan gehalten ist.

Irrespective of this, independent protection is claimed for a scraper, which has the following features:

• Scraper 1 for stripping a cosmetics applicator with a holding portion 2 for fixing the scraper 1 to a Cosmetic storage container 6, characterized in that the scraper 1 has several in the direction of action successively arranged Abstreiforgane 3, 4, 5, of which at least one scraper is held only by means of several columns 7 on the holding portion 2 or on the adjacent scraper.

For both of the above-mentioned objects, for which independent protection is desired regardless of the separately established claims, it applies that these objects can be further developed by using the features contained in the explicitly set out subclaims.
