Description

GENERAL DESCRIPTION OF THE INVENTION

The present invention relates to cosmetic units with a cosmetic storage container for storing the cosmetic and an applicator according to the preamble of claim 1.

TECHNICAL BACKGROUND

Typically, cosmetic units of the type in question consist of an applicator which, in its ready position, is completely immersed in a stock of cosmetic mass held in the cosmetic storage container. The applicator is typically connected via a stem to a closure. The closure seals the cosmetic unit from leaking when the applicator is in its ready position in the cosmetic container.

As a rule, either a thread or a frictional connection is used to hold the closure in its closed position securely on the cosmetic storage container. Such frictional connections usually look like that the closure has a tubular skirt which is frictionally pushed onto the neck of a Kosmetikvorratsbehälters. The whole thing can be supported by a locking connection. In this case, the neck of the cosmetic storage container, for example, carries a local, usually annular elevation or a corresponding depression, with which the apron of the closure (additionally) locked in a form-fitting manner.

The screw caps have the disadvantage that the thread can become dirty over time and then becomes unsightly.

The frictional connections between the closure and the cosmetic reservoir have the disadvantage that it is not sufficiently ensured that the closure is placed in a particular case close to the cosmetic reservoir. Here it happens occasionally that the closure is not pressed far enough on the cosmetics reservoir. The result is then under unfavorable circumstances, leakage of cosmetics from the cosmetics reservoir, which is of course extremely annoying.

Because of this, it has already been proposed to fix the closure of a cosmetic reservoir by means of magnetic means on the cosmetic reservoir. In that regard, the European patent EP 1 095 870 B1 directed.

However, this patent describes a very expensive to manufacture construction, which is reserved due to the costs associated with their production in practice exclusively the exclusive products.

OBJECT OF THE INVENTION

On the other hand, it is the object of the invention to provide a simplified producible closure that can be held on the cosmetic reservoir by means of magnetic means or on a cosmetic unit equipped therewith.

INVENTION SOLUTION

The solution follows with the means of claim 1.

Accordingly, a cosmetic unit is provided with a cosmetic storage container for storing cosmetic. The cosmetic unit includes an applicator for applying the cosmetic. The applicator passes directly or via a handle into a closure for sealing and closing the cosmetic reservoir. In this case, the closure is held in its fully closed position by the magnetic attraction forces between a first magnetic component carried by it and a second magnetic component carried by the cosmetic storage container.

According to the invention, it is provided that the first magnetic component consists of hard magnetic powder or soft magnetic powder. A hard magnetic powder is understood as meaning a powder of permanently magnetic particles. By contrast, a soft magnetic powder is understood as meaning a powder of particles which can be attracted by a permanent magnet, however formed. The term "integrally embedded in the respective plastic" means that the respective powder has been added to the relevant plastic in the molten state and mixed with it before the resulting mixture has been injected into the corresponding injection mold. Due to this, the respective particles are enclosed on all sides, but at least substantially on all sides, by a plastic layer. However, they only assume a distance from each other which is so small that it does not cancel out the overall intended magnetic effect, but only slightly reduces it.

At the same time, the melt into which the respective particles have been mixed has been such that at least the predominant part of the particles could align in the melt before the mass has solidified. In this way and As a result, various particles form a larger permanent magnet or a larger magnetically attractable region.

It is important to note that not the entire closure or not the entire cosmetic reservoir or the entire scraper must contain the corresponding powder. Rather, it is particularly advantageous here if the production of the relevant component is carried out with a local injection. Explained by the example of a scraper, this can be something like that in the mold cavity, which later forms the complete scraper, first from a first injection nozzle shot a plastic material is injected, which is mixed with the respective powder. The so injected mixture forms, for example, the collar of the scraper, with which this rests later on the upper face of the bottle neck. However, the mold cavity is not completely filled by this first shot, instead plastic powder mixed with powder, which forms the remainder of the scraper, is shot in a second shot. In this way, a scraper, for example, exclusively or substantially exclusively in the area of its covenant magnetic properties has. In the same way can be moved, for example, with the cap, but possibly also with the cosmetic reservoir.

PREFERRED EMBODIMENTS OF THE INVENTION

It has proved particularly favorable if the hard magnetic powder is a hard ferrite or rare earth magnetic powder or a mixture thereof. Even when pressed in powder form together with plastic or other binder, these substances form magnets with a strong tightening force.

Furthermore, it is particularly advantageous if the soft magnetic powder is a soft ferrite, iron or steel powder. The substances mentioned give a good tightening force in the field of a permanent magnet.

Ideally, the individual particles of the hard magnetic powder and / or the soft magnetic powder are predominantly, better than 90% and optimally fully equipped with an average diameter smaller than 0.5 mm and preferably smaller than 0.15 mm. This does not mean that the particles have to be globular. Rather, the average diameter is the diameter of the smallest imaginary sphere into which a single particle can be trapped without impacting the skin of the sphere.

Preferably, the individual particles of the hard magnetic powder and / or the soft magnetic powder are glued to the plastic in which they are embedded, as occurs when the particles are mixed with the molten plastic mass (preferably in an extruder) and then at a pressure of preferably be injected more than 500 bar in an injection mold.

FURTHER OBJECT OF THE INVENTION

Another object of the invention is to provide a cosmetic unit, the closure of which can be fixed particularly secure by means of magnetic forces on the cosmetic reservoir.

INVENTION SOLUTION

The solution is carried out by the means of the independent further main claim, in particular by means of claim 6, which claims, inter alia, independent protection, without reference to the preceding claims.

Also in the context of this inventive solution, a cosmetic unit is provided with a cosmetic reservoir for storing the cosmetic and with an applicator for applying the cosmetic. The applicator passes into a closure for tightly closing the cosmetic reservoir.

According to the invention, the closure has a sealing wedge. At the same time, the opening of the cosmetic storage container carries a seal which forms a seat into which the sealing wedge is sealingly inserted when the cosmetic unit is completely closed. The sealing wedge is designed so that it is driven by forces acting in the direction of the longitudinal axis L of the cosmetic reservoir into its associated seat. Due to its wedge-shaped shape, it converts the force acting in the direction of the longitudinal axis L into a force acting obliquely thereto. In sum, the resulting force is greater in magnitude than the force acting in the direction of the longitudinal axis L. Preferably, the contact surface between the sealing wedge and the seat is limited to a generally conical annular surface, which has an extension of not more than 4 mm, more preferably not more than 2.5 mm, transversely to the circumferential direction.

In all of this, the closure has a first magnetic component while the reservoir has a second magnetic component. The two magnetic components are designed and positioned such that they are in a substantially completely closed cosmetic unit, ie when the closure measured in the longitudinal direction L except for one Distance 1.5 mm has reached its end position, tighten so that a force acts, which pulls the sealing wedge into the seat and brings the closure completely in its final position.

In this way, a closure is produced, which is automatically closing.

If present and correspondingly interacting with the stem of the applicator, the scraper is designed so that its frictional forces, with which it rests against the stem, are smaller than the magnetic forces in the direction of the longitudinal axis L, in the said distance from the end position occur.

FURTHER PREFERRED EMBODIMENT OF THE INVENTION

It has proved particularly expedient to carry out the seal as an integral part of the scraper. In this way no additional component is needed. The assembly effort is reduced, because a scraper must be mounted in any case.

Preferably, the scraper consists of two sections of different plastics. These two sections can be glued together, which is not preferred. Preferably, the two sections are welded together, ideally as is the case with two-component injection molding, when a compatible plastic material is sprayed onto a first already-molded plastic material and then joins at the contact surface therewith. In this way, it is very easy to produce a particularly soft portion of the scraper, which forms a reliable seal with the closure, even if the forces by means of which an adaptation takes place in the length, manageable. The scraper effect is not impaired as such, because a harder plastic can be used for the actual stripping acting section. In this way, the danger that the actual scraper is everted or otherwise unduly deformed when the applicator is pulled through it is avoided.

Ideally, the seal or portion of the wiper that forms the seal is made of a foamed plastic. Foamed plastics are particularly flexible and can cling well to a sealing wedge. Preferably, the surface of the foamed plastic, which interacts directly with the sealing wedge, executed closed cell. This means that on the surface at least a skin is present, which forms a barrier against the foam cells behind it in the radial direction.

As a particularly favorable material for producing such a seal or a portion of the scraper, which forms a seal, LDPE has been found. This material is resistant to cosmetic substances and sufficiently soft to fulfill its intended function.

Preferably, the sealing wedge is formed by a portion of the stem. Ideally, the stem in the section where it forms the sealing wedge is hollow inside. This avoids deviations in shape of the sealing wedge, as they can arise, for example, when a thick-walled or solid plastic part in the region of its core cools only with a time delay and thereby noticeably shrinks.

It has proven to be particularly favorable when the closure has an additional tubular, preferably cylindrical guide section adjacent to its handle, which with its peripheral surface overreactions or engages behind the circumferential surface of a tubular, preferably cylindrical guide section of the cosmetic storage container. The contact takes place so that the peripheral surfaces lie directly against each other.

In this way, the closure is positively secured on the cosmetic reservoir against so-called tilting. This means that the closure is positively held by the cosmetics reservoir, even if, for example, when transported in a bag or handbag a bending moment acts on him, which tends to pivot the closure relative to the cosmetics reservoir. This ensures that such a constellation does not have to be caught or at least not predominantly by the magnetic components. Rather, the magnetic components are in such a constellation predominantly only responsible for preventing the closure can be removed by forces in the direction parallel to the longitudinal axis L.

When designing the guide sections, care must be taken that they abut each other without friction or with a slight preload, which merely leads to frictional forces which can be overcome by the magnetic components at least when the closure is at a distance of 1.5 mm has approached its already described above end position.

Ideally, the guide section is part of the neck of the cosmetic storage container.

Preferably, the two magnetic components are located on the closure and on Cosmetic storage container, relative to the longitudinal axis of the cosmetic unit, in alignment with each other, ideally together with the guide portion of the closure. In this way, very slim-fitting closures can be realized.

However, it may be favorable if the first magnetic component forms an annular region. The same may be favorable for the second magnetic component. The annular regions may be an integral part of the closure or cosmetic reservoir. But it may also be in one or both of these rings to separately prepared rings, which are subsequently mounted on the closure or the cosmetics reservoir. The latter is recommended for small series, while for large series with the closure or the cosmetic reservoir integral production of at least one of the two rings is preferred.

For some applications, it has proved to be particularly useful if the annular portion of the first magnetic component and the annular portion of the second magnetic component are arranged side by side in fully closed closure in the direction of the longitudinal axis of the Kosmetikeinheit - preferably so that one annular portion of the other substantially completely or completely surrounds, so that thus seen one of the two annular areas in the direction of the longitudinal axis L is completely absorbed by the other of the annular areas. In this way it can be ensured that the contact surfaces, over which the facing surfaces of the magnetic components abut against each other, are respectively cleaned by the closing movement, which performs the closure relative to the cosmetic reservoir. Any adhering contaminants or even soft magnetic particles adhering to them, which have been attracted to the environment, are stripped off in the course of the closing movement.

In some cases, it is favorable if the first magnetic component is designed as a circumferentially seamless self-contained ring of permanent magnetic material or soft magnetic material. In that case, it may additionally be advantageous if the second magnetic component is designed as a circumferentially also seamlessly closed ring of a soft magnetic material or of a permanent magnetic material.

Provided that the first magnetic component and the second magnetic component are both made of permanent magnetic material, care must be taken that these permanent magnets in the closed position, which is to take the shutter are aligned so that a south pole on a permanent magnet opposite to a north pole on the other permanent magnet , Only then does the required attraction occur and the magnets do not interfere with each other.

It has proved to be particularly favorable if the ring forming the second magnetic component is frictionally pressed onto the neck of the cosmetic storage container and / or is at least partially pressed into a groove on the neck of the cosmetic storage container. In this way, a very simple assembly is possible. The ring forming the second magnetic component merely has to be pushed from above onto the neck of the cosmetic storage container with the aid of a corresponding placement machine.

It is also expedient if the ring forming the first magnetic component is frictionally pressed into an opening of the closure and / or at least partially engaged in a groove of the closure or its skirt. Even then a very simple assembly is possible. The insertion machine only has to arrange the corresponding ring coaxially with the closure and then insert it into it.

In all of this, the positioning of the first and second magnetic components is preferably adjusted so that when the shutter is fully closed, one surface of the one ring abuts directly against the surface of the other ring without the interposition of a weakening air or third material gap. In this way, particularly large holding forces can be realized.

Occasionally, a particular closure position of the closure is enforced so that it can really only be fixed to a single position on the cosmetic storage container. There is a need for this in particular if the closure is asymmetrical and / or carries a decorative imprint and therefore it is to be ensured that the closure is correctly positioned in its closed position in order to depict the desired overall design of closure and bottle. For this purpose, it is provided that the first and the second magnetic component are either multi-part or locally different magnetic poles are impressed, which are distributed irregularly such that the magnetic poles only at least partially repel when the shutter in a certain orientation relative to Cosmetic storage container is placed on this. In such a case, it will usually be necessary for both the first and second magnetic components to be hard magnetic.

EMBODIMENTS

SUMMARY OVERVIEW

The 1 shows an overall view of a cosmetic unit according to the invention 1 , which can have different very different designs.

As you can see, this cosmetic unit exists 1 from a cosmetic storage container 2 , an applicator 3 and a closure 4 ,

The cosmetic storage container preferably has the shape of a bottle. The bottle preferably has an elongated shape. Their measured along the longitudinal axis L length / height is then usually at least a factor of 3, better by at least a factor of 5 greater than its largest extension perpendicular to the longitudinal axis L.

The applicator 3 and the closure 4 are over a stalk 5 connected with each other. The closure is preferably of a cap 8th overlapped, which gives the outer surface of the closure an optically and haptically high-quality impression. The cap 8th is in many cases of metal, in many preferred cases aluminum or a similar, very ductile material is used.

The cosmetic reservoir 2 is preferred with a neck 6 fitted. The neck is compared to the rest of the cosmetic reservoir is a bottleneck, can be removed through the use of the applicator cosmetic mass from the cosmetics reservoir. Preferably, in the throat 6 a scraper 7 used. The scraper 7 brushes excess cosmetics off the applicator 3 from.

The cosmetic storage container and the closure can be connected to one another threadlessly in order to seal the cosmetics unit without leaks or hermetically.

Preferably on the neck 6 is a second ring 9 fixed, which forms the second magnetic component here. It is particularly favorable if the second ring consists of a soft-magnetic material which can be magnetically attracted, but does not remain magnetically permanently or even to a significant degree.

First of all, it should be said that the second ring 9 frictionally engaged on the neck 6 of cosmetic storage container 2 may have been pressed. Alternatively, however, an adhesive connection can also be provided. Where a particularly secure connection is to be achieved, a combination of an adhesive connection and a frictional press fit is provided.

The first magnetic component is in the present case as so-called. First ring 10 educated.

This first ring can be a material integral part of the closure 4 which will be discussed in more detail below.

Alternatively, he can act as a discrete ring 10 be formed, which is made separately from the closure and / or cosmetic reservoir and is mounted later. In such a case is Also, the first ring regularly formed as a circumferentially self-contained part.

In this type of embodiment or fastening of the first and the second ring or the corresponding magnet components, it is particularly favorable that in each case one surface of the first and of the second ring contact one another directly, without separation through an intermediate layer, such as a plastic layer, when the closure is completely closed to come to rest. As a result, particularly high holding forces become available because the two rings forming a magnetic unit are not separated by an air gap when the shutter is in its fully closed position. This has significant advantages, because this way the holding force can be optimally utilized, even in the event of failure of a weaker magnetic material. This applies to all embodiments explained below.

FIRST EMBODIMENT

The 2 shows a first embodiment of the cosmetic unit according to the invention 1 , wherein from the cosmetic unit 1 only a section in the region of the connection between the closure and the cosmetic reservoir is shown.

Good to see here is a section of the cosmetics reservoir 2 in the neck 6 passes. Into the throat 6 is a wiper 7 used, preferably engaged, which is not shown here as such. The neck 6 gets off the lock 4 overlapped. The closure 4 can on the outside of him a cross-cap 8th wear, which gives it special optical and haptic properties.

As you can see, the cosmetic reservoir is wearing 2 For example, in the area of his shoulder next to the neck 6 , a second ring 9 , The second ring forms the second magnetic component according to the invention. The second ring 9 is here preferably designed as a separately manufactured and preferably in the circumferential direction self-contained component. He is subsequently to the cosmetics reservoir 2 mounted. It is particularly favorable if the cosmetics reservoir 2 this has a circumferential groove into which the second ring 9 can be used, preferably to bond there with the groove bottom and / or the side walls of the groove or to weld.

Ideally, the second ring is made of a hard magnetic material, so that a permanent magnetic field emanates from it.

The first ring 10 however, no separately manufactured and subsequently mounted component. Instead, it is a preferably integral part of the closure 4 , The first ring then consists, for example, of a soft magnetic powder whose powder particles are at least partially embedded in the plastic mass which forms the closure. It is particularly favorable when the apron to be explained in more detail below 11 is the area interspersed with the powder particles of the soft magnetic powder. Ideally, the area of the closure 4 , which is penetrated by the soft magnetic powder, on the lowest, the shoulder next to the bottleneck facing third of the closure 4 limited. In this way an unnecessary weakening of the closure is avoided.

The second ring 9 from which a magnetic field permanently emanates, is able to be the first, an integral part of the shutter 4 forming ring 10 magnetically attract. Ideally, an end face of the first ring touch each other 10 and the second ring 9 immediately when the shutter 4 its the cosmetics reservoir 2 completely occlusive position on the neck 6 occupies.

As you can see, the first and the second ring are all designed and positioned so that they touch each other directly at one of their faces, which has a particularly high holding power result.

It is also noteworthy that directly or indirectly on the closure a damping element 16 can be appropriate. In the present case, the 2 shows is the damping element 16 indirectly on the closure 4 appropriate. The damping element 16 Namely, here is preferably an integral part of the existing in the specific case of plastic cap 8th , The cap 8th overlaps the closure 4 and gives it special optical and tactile properties. The damping element 16 is in the present case at the shoulder of the cosmetic reservoir 2 next to the neck 6 lies, opposite free front of the cap 8th appropriate. The damping element is designed here as a resilient extension, which gives something when the second ring 9 the first ring 10 attracts fast and hard. In this way, the magnets do not clack against each other in their clash, but there is only a muffled end movement.

It is particularly favorable if a guide section is formed both on the container neck and on the closure cap 4 or on their apron 11 , The function of these guide portions, which are in direct contact with each other when the shutter is fully in its closed position, will be discussed later.

The same applies to the sealing wedge 17 The shutter 4 and the seat assigned to it on the side of the cosmetic storage container 18 , These two components are optimally always present in the solution according to the invention in any form and their function will be explained in more detail later.

The inner diameter of the scraper 7 and the outer diameter of the stem 5 are coordinated so, as explained later.

SECOND EMBODIMENT

The 3 shows a second embodiment of the invention of 1 shown cosmetic unit 1 ,

Again, the bottleneck is easy to recognize 6 of the cosmetic storage container shown in detail 2 , the cutout of the lock 4 and a section of the scraper 7 ,

The special feature of this embodiment is that the first ring 10 which also here forms the first magnetic component, again not formed separately, but as an integral part of the scraper 7 is trained. The scraper 7 is for this purpose preferably equipped with a collar, the mounted scraper 7 preferably on the free end of the bottle neck 6 comes to the plant. At least in the area of this collar, and preferably only in the area of this collar, hard or soft magnetic particles are integrally incorporated in the plastic of the scraper - whereby the incorporation of soft magnetic particles is preferred. Because then it is ensured that in the area of the bottleneck 6 it is not unintentionally that magnetically soft particles from the environment are retained, which present themselves in a disturbing way or are even taken away by the applicator when it passes through the bottleneck 6 is pulled out. This means that the second magnetic component is an integral part of the scraper 7 is.

When the scraper 7 in turn stuck with the cosmetics reservoir 2 or its neck 6 is connected - for example by locking -, then he can do the closure 4 to keep in its fully closed position.

Of course, this is a prerequisite that the shutter 4 carries the first magnetic component, with which cooperates the second magnetic component when closing. The first magnetic component on the closure 4 can either as a separate, subsequently attached to the closure first ring 10 be executed. In this case it is particularly preferred if the closure 4 at the transition between his apron 11 and the stalk 5 or the sealing wedge 17 wearing a groove in which the first ring 10 is attached. Alternatively, it is of course also possible not to form the second magnetic component separately, but as an integral part of the closure 4 , which is not represented figuratively here.

In this construction as well, a guide section is formed both on the container neck and on the closure 4 ,

Also in this construction forms the stem 5 a sealing wedge 17 out.

The inner diameter of the scraper 7 and the outer diameter of the stem 5 are coordinated so, as explained later.

THIRD EMBODIMENT

The 4 shows a third embodiment of the invention.

In the 4 The neck is easy to recognize 6 of cosmetic storage container 2 and the closure 4 which in the here only indicated stalk 5 passes. Again, the closure 4 from a cap 8th overlapped. Also visible is the area of the scraper 7 which forms the collar with which the scraper optional on the free end of the neck 6 is applied. As you can see well, the closure points 4 here in the area of his apron 11 a ring cutout 14 on.

This embodiment differs from the two preceding embodiments in that the first magnetic component and the second magnetic component are both here in the form of separate, preferably circumferentially closed, rings. Both of these rings were made separately and were subsequently attached to the cosmetic reservoir or the closure.

The first ring 10 is ideally on the closure 4 or more precisely, on the front end of an apron 11 of the lock 4 attached. The first ring 10 is preferably in the ring cutout 14 at the lock 4 or his apron 11 used and then on its outer periphery of the apron 11 of the lock 4 overlapped. He is therefore predominantly hidden. In addition, the area over which the first ring is enlarged in this way 10 with the lock 4 can be glued. Alternatively, it is also possible to think of a press fit here. For this purpose, then the first ring 10 pressed into the half-groove, the ring cutout 14 the apron 11 at the closure 4 formed.

Theoretically, both rings can be made of hard magnetic material. However, they must then be provided with locally different poles, so that in each case a south pole on one ring with a north pole on the other ring is opposite. This effect can be used to define a preferred rotational position in which the shutter 4 exclusively on the storage container 2 can be fixed. For this purpose, it is necessary to provide both rings of hard magnetic material with asymmetrically arranged poles. This means that, viewed in the circumferential direction, different angles are provided between adjacent poles. If this is done, then there is only a single position in the best case, in which the first ring and the second ring attract each other, because only in this position in each case a south pole on the first ring a north pole on the second ring is exactly opposite and vice versa.

If one of the two rings is made of soft magnetic material, then preferably the first ring 10 made of a hard magnetic material, ie the first ring then has permanent magnetic properties. He is able to permanently attract other soft metallic parts in his environment.

The second ring 9 turn is on the neck 6 of cosmetic storage container 2 attached. Ideally, he will be through a press fit on the neck 6 held. For this purpose, it is advantageous if the inner diameter of the second ring 9 0.08 mm to 0.4 mm smaller than the outer diameter of the neck 6 , The second ring 9 is then from the free end of the neck 6 pressed in, in the of 4 shown position. By thus resulting pressure, the second ring 9 kept safe.

With all this, the first ring 10 and the second ring 9 preferably arranged relative to each other so that they are aligned in the direction parallel to the longitudinal axis L of the cosmetic unit.

As you can see, the first and the second ring are all attached to the cosmetic reservoir and the closure so that they each touch directly on one of their faces, which has a particularly high holding power result.

Based on 4 you can see very well what the actual function of the apron 11 is.

It's like that, the apron 11 on its inner peripheral surface a guide portion 12 The shutter is fully closed 4 the outer peripheral surface of a tubular guide portion 13 engages the container neck 6 is trained. In this way come the leadership section 12 forming inner peripheral surface of the skirt 11 and the outer peripheral surface of the guide portion 13 at the neck of the cosmetics reservoir directly against each other to the plant. Ideally, even a fit is chosen here, which is so tight that the two peripheral surfaces abut each other with a bias.

This embodiment with the guide sections 12 and 13 has the advantage that the magnetic components for the closed-holding of the cosmetic unit only have to apply such holding forces, which are directed in the direction parallel to the longitudinal axis L. Any bending stress that acts on the closure and attempts to pull the closure from the container by a tilting movement, is completely from the two guide sections 12 and 13 therefore does not catch and load the two magnetic components. In this way, a significant contribution is made to the fact that no unintentional opening of the cosmetic unit can occur, for example by the cosmetic unit being exposed in a handbag or a trouser pocket to a bending load.

This function of the skirt is preferably present in all embodiments according to the invention, even in the case of those explained in the introduction.

In this embodiment, you can see very well the already mentioned seal wedge 17 , The seal wedge 17 is here as part of the stalk 5 educated. For this purpose, the stem points 5 an inside hollow section, which widens conically outwards. Ideally, the scraper 7 in turn, with a conically shaped seat 18 provided in its slope the sealing wedge 17 adapts. In this way, the sealing wedge closes 17 the passage between the stem and the scraper already tight when relatively small forces in the direction of the longitudinal axis L act on him.

At the same time the sealing wedge carries 17 to prevent the closure from being inadvertently opened when subjected to a bending moment perpendicular to the longitudinal axis L. This is because of the neck 6 of cosmetic storage container 2 on the one side, form-fitting on the apron 11 abuts and on the other side over the scraper form-fitting against the sealing wedge 17 is applied. In this way, the closure can 4 optimally supported on the bottleneck, which promotes the achievement of the aforementioned effect as best as possible.

In general, it can be said from this embodiment that the stem 5 and its sealing wedge 17 on the one hand and the scraper 7 on the other hand have to be coordinated so that The resulting friction is less than the maximum tightening force between the first and the second magnetic component in the direction of the longitudinal axis L. In this way, it is ensured that the closure, if on the neck 6 is always placed completely in its closed position. This is preferably true for all embodiments discussed herein.

FOURTH EMBODIMENT

The 5 shows a particularly advantageous embodiment, as the first and second magnetic component can be attached, if they are each as first and second magnetic ring 9 and 10 are formed.

The 5 again represents a section enlargement of the 1 so that's for the 4 what is said in the introduction applies mutatis mutandis. As you can see well, the closure points 4 here in the area of his apron 11 again a ring cutout 14 on. In the ring cut is positively the first ring 10 be spread. For this purpose, the first ring 10 have at its front in the direction of spread edge an insertion bevel, as shown in the 5 it can be seen without a separate reference number has been assigned.

Conveniently, the first ring 10 here have a recess into which a corresponding projection of the closure 4 or his apron 11 snaps to the first ring 10 especially safe to keep.

Also good to see is based on the 5 that the second ring 9 in turn, form-fitting to the cosmetic reservoir 2 or its neck 6 can be locked. For this purpose, wearing the neck here 6 of cosmetic storage container 2 in turn a ring cutout 15 , In this ring section, the second ring 9 locked. You then make use of the fact that the neck 6 of cosmetic storage container 2 is compressible, allowing the neck during assembly of the ring, when this from the top, free end of the neck ago down to the area of the ring section 15 pushed over the neck, can be compressed, and then spring back apart as soon as the second ring 9 his position in the ring cutout 15 has reached.

Alternatively, there is the possibility of not later aufzuspreizen the first ring, but already in the production of the cosmetic reservoir in the injection mold or the blow mold and form the cosmetic reservoir so that the second ring 9 at least partially embedded in it, as well as from 5 shown.

Very good on the basis of 5 again, it can be seen that, ideally, a damping element formed separately and additionally by other components is provided. Here is, for example, the first free end of the cap 8th a buffer, which preferably has a circumferential annular shape, has been molded from a soft plastic material, for example a soft elastomer. This damping element 16 prevents a hard, clacking snap when the first and second rings tighten.

FIFTH EMBODIMENT

The fifth embodiment substantially corresponds to the fourth embodiment, so that what is said there applies mutatis mutandis, unless expressly stated otherwise in the drawings and the differences mentioned below.

In this fifth embodiment, the first and second magnetic components are positioned relative to each other so as to be fully closed 4 overlap at their periphery or even substantially or completely aligned with each other in the circumferential direction.

The one of these two magnetic components, which has permanent magnetic properties, is poled so that it tends to attract the other magnetic component such that ideally both magnetic components overlap as much as possible in the circumferential direction. In other words, the polarity is such that the magnet components tend to align so as to be aligned in the radial direction. This also applies if both magnetic components are permanently magnetic. Unlike in the embodiments described so far, the first and the second magnetic components come to rest here at least partially next to one another in the radial direction. Preferably, the first and the second magnetic component are equipped with the smallest possible clearance of 0.08 mm to 0.75 mm and better still with the smallest possible clearance of 0.08 mm to 0.4 mm. This small clearance means that on the one hand, the air gap between the magnetic components is small and therefore their holding power is impaired as little as possible. On the other hand, this small clearance causes the two magnetic components to slide over one another without friction or jamming or hanging.

The above applies if the first and the second magnetic component as a separate first and second ring 9 respectively. 10 are formed, which subsequently to the closure 4 or the cosmetic storage container 2 have been mounted. That is true but also if the first and / or the second magnetic component as an integral part of the closure 4 or of the cosmetic storage container 2 are formed, ie as a powder, in the plastic of the closure 4 or of the cosmetic storage container 2 is embedded.

This positioning of the first and second magnetic components has the distinct advantage that some sort of self-cleaning occurs on the first and second magnetic components. If, for some reason, one of the rings has attracted a soft magnetic particle with its circumferential surface from the environment, then this soft magnetic particle is pushed aside by the sliding of the rings in the direction of the longitudinal axis L and then does not lead to a permanently small air gap between the first of the second magnetic component is maintained.

As already mentioned above, there is also the possibility of the first and the second magnetic component as a separate first and second ring 9 and 10 form, each with a hard magnetic property. Again, that by asymmetrically distributed on the circumference poles are formed, can be specified that the two rings 9 and 10 can only be pushed over one another in a certain rotational position.

SIXTH EMBODIMENT

The 6 and 7 show a sixth embodiment. In this sixth embodiment, a plurality of individual magnets 19 at the lock 4 and at the same time several corresponding individual magnets on the cosmetic storage container 2 used.

These individual magnets 19 can subsequently into corresponding openings in the cosmetics reservoir 2 or the closure 4 have been used, for example by pressing into corresponding receiving blind holes.

The individual magnets may also have already been inserted into the injection mold and / or the blow mold and then in the course of injection molding or the container blowing in the material of the closure 4 or cosmetic reservoir 2 have been embedded.

With these individual magnets 19 Optionally, the same can be realized, which has already been described above for the permanent magnet rings. If the individual magnets are not arranged distributed symmetrically in the circumferential direction, but are positioned according to asymmetrical in the circumferential direction and each south pole on Kosmetikvorratsbehälter a north pole at the corresponding point of the closure 4 corresponds (and vice versa), then this can possibly specify a single position in which the shutter 4 on the cosmetic storage tank 2 can be set in the closed position. In all other positions, at least a part of the magnets repel each other and thereby prevent the closure 4 reaches its full closed position, or give the user at least a haptic signal that he does not put the closure in the correct position, but still has to turn something.
