Description

The invention relates to a refillable cosmetic pen and an associated cartridge.

TECHNICAL BACKGROUND

Cosmetic pencils are often built as so-called lead pencils. In the case of lead pencils, a lead is provided which consists of the material to be applied. The consistency of the lead is typically adjusted - often by using a corresponding proportion of fat or wax - so that when applying the tip of the lead is pulled over the skin area to be treated with the necessary pressure and then the required amount of the material to be applied is pulled from the lead is peeled off and deposited on the skin area.

Mechanical pencils, in which the leads are held in a wooden sleeve, similar to colored pencils, have proven very effective. The sleeve made of wood can be chipped with a sharpener like a pencil sharpener. In this way, the user can repeatedly adjust the tip of the cosmetic pencil to its optimal shape until the pencil is used up. Recently, sleeves made of plastic have also been used. The disadvantage of this type of cosmetic pencil is that a relatively large part of the lead is chipped when the tip is reconditioned and thus ultimately remains unused.

To remedy this, pin systems with mechanisms for advancing the corresponding mines are often offered. With such pens, the mine can be used much more effectively.

Some systems, such as glue sticks for paper handicrafts, use a threaded spindle that penetrates the middle of the hollow mine in order to be able to screw the piston plate running on it, which supports the mine from its rear, forward.

In such systems, the entire pen, including the feed mechanism, is usually discarded as soon as the lead is used up. This is particularly true in the cosmetics sector, where, for hygienic reasons, it is unthinkable to reintroduce the spindle, which is still contaminated with residues from the old, used lead, into the new lead as it is.

Due to the megatrend of sustainability and increasing environmental awareness, consumer behavior in everyday life has already changed significantly in a wide variety of areas in recent years. Some consumers are already questioning their entire consumption behavior and paying attention, for example, to more conscious consumption, support for recycling cycles or a reduction in superfluous packaging. In order to be able to offer consumers sustainable product solutions, companies from the beauty and body care sector and in particular from the care cosmetics sector have already developed refillable product concepts and established them on the market. For example, in the case of liquid soaps for washing hands, refill packs are offered as refills, which have a reduced proportion of packaging than the main packaging when first purchased. This allows the end user to reduce their own packaging consumption. However, the use of post-consumer recyclate (PCR) to support existing recycling cycles is made more difficult by the requirements of the Cosmetics Directive (EC) No. 1223/2009, since the use of recyclates without further thorough tests for the purity of the starting materials is prevented and the manufacturer may not be able to guarantee product safety.

Due to the increasingly important idea of using global resources as sparingly and sustainably as possible without having to forego comfort and attractive design, interest in cosmetic pencils that offer the option of easy and resource-saving refill refills has recently increased significantly. The systems considered in practice as an alternative to the above-described glue stick for paper handicrafts could not gain acceptance. In this context, the idea has already been toyed with of accommodating the refill in a separate housing part, which is separated from the rest of the cosmetic applicator to be used further and can be discarded when the refill contained in it is exhausted. However, a serious deficit proved to be the need to intervene in the feed mechanism in the course of removing the housing part containing the spent lead residue. This resulted in the need, which was felt to be disadvantageous, to start the feed mechanism again with skilled fingers in the course of installing the housing part with the fresh lead.

In addition, with such systems, at least one component of the feed mechanism must also be discarded with the replacement of the housing part containing the mine. This creates large amounts of waste.

Another system is from the European patent application EP 3 332 667 A1 known.

This system has an extremely inconvenient operating mechanism: the mine can be deployed using the operating mechanism, which consists of a simple push rod. However, it cannot easily be retracted again. This option also does not exist if the user has accidentally deployed too many mines. In order to retract the mine again, the operating mechanism must be turned back. Then you have to move the mine back by gently pressing on its tip. Especially with softer mines, unintentional deformation often occurs, which prevents the mine from being pushed back even further.

Furthermore, with these pens, the user can only change the cartridge or refill very inconveniently.

TASK

In view of the above, it is a first object of the invention to provide a cosmetic applicator or pencil whose lead can be changed without special skill. At the same time, the amount of waste generated when changing the mine should be reduced as far as possible.

SOLUTION

A first solution to this problem according to the invention is as described by the features of claim 1 .

According to the invention, a refillable cosmetic pencil with a lead is proposed, from which the cosmetic mass to be applied can be removed, so that at least temporarily a layer or film results on the hairy or preferably at least essentially hairless body part to be treated.

The cosmetic pen has a cartridge holder to hold a cartridge that can be replaced without tools. This cartridge—preferably closed on all sides even in the ready-to-use position except for a lead outlet opening of the really necessary size—contains the lead, mostly completely or at least substantially completely. The mine therefore does not have to be touched with the fingers when changing the mine. This offers considerable hygienic advantages and prevents the lead from being damaged when the lead is changed.

The cosmetic pencil is optionally equipped with a feed mechanism. This is used to push the mine out of the cartridge and pull it back into the cartridge and is designed accordingly. This ensures that there are no handling problems even if the user has extended the mine too far.

The cosmetic pencil has a handpiece, in particular in the form of a grip sleeve, which is used to actuate the feed mechanism.

The cosmetic pencil according to the invention is characterized in that the cartridge only accommodates the mine. Alternatively, the cartridge houses only the mine and a cartridge plunger. In addition, there are at best secondary components in the cartridge. A sealing element, for example in the form of O-rings, or a stop, locking or locking ring or a sealing plug are conceivable in this respect. Ideally, such further components are also missing, so that only the mine and the cartridge plunger find space in the cartridge, with the cartridge plunger being able to be formed by a sleeve or cartridge case.

In any case, in the loading and unloading position, the feed mechanism is completely outside the cartridge. This eliminates the need to discard part of the feed mechanism with each cartridge. Even more important is the fact that in this way the user does not have to concern himself with the functioning of the feed mechanism. Because the feed mechanism always works "by itself" without any external intervention, even after a cartridge change.

According to the invention, the feed mechanism includes a feed rod with a coupling part. This coupling part is designed in such a way that it closes by simply advancing the feed rod against the cartridge or the closing cone on the cartridge and thus connects with the cartridge piston in a form-fitting manner. This means that the feed mechanism can be coupled and uncoupled to a cartridge that has just been inserted or removed simply by actuating the feed mechanism as intended. In addition, there is no need for user intervention in the feed mechanism. It is therefore not necessary to understand how the feed mechanism works in order to carry out the cartridge change without complications. This simplified cartridge change decisively increases consumer acceptance of the system according to the invention.

The means provided according to the invention simplify the cartridge change in such a way that, for the first time, it is also possible to use several unused cartridges with different ones at the same time paints or cosmetics seems practicable. For example, the user can first insert a cartridge with a blue lead and apply it as eye shadow. The unused cartridge with the blue lead is then removed. It is replaced by a cartridge with a black refill that is about to begin, in order to emphasize the eye with a black eyeliner.

A second solution according to the invention to the problem mentioned at the outset appears as described by the features of claim 31 .

According to the invention, a refillable pen with a mine is proposed, from which the mass or color to be applied can be drawn off—as already explained above in the context of the presentation of claim 1 to a large extent. However, protection is not only claimed here with reference to one of the preceding claims, but also in isolation.

The cosmetic stick or pen proposed within the scope of this invention is characterized in that its cartridge holder is designed in such a way that it can be loaded with a cartridge without having to completely or partially separate the feed mechanism from the cartridge holder. It is particularly favorable if the cartridge holder is designed in such a way that the cartridge can be loaded into the cartridge holder by simply snapping it into place or clicking it in or plugging it in. This significantly simplifies handling. Changing a cartridge no longer requires disassembling the cartridge holder from the handpiece and interfering with the advancement mechanism and then restarting it later. Instead, all components of the feed mechanism remain anchored in place to perform their function. Your interaction will not be disturbed.

ANOTHER TASK

A further, second object on which the invention is based is to specify a refillable cosmetic pencil or pen that can be fitted with cartridges that have different leads, in the simplest case leads of different colors, easily and essentially without smearing different lead substances.

SOLUTION ACCORDING TO THE INVENTION

A first solution to this further problem according to the invention is as described by the features of claim 17 .

According to the invention, a refillable cosmetic pencil with a refill is proposed, from which the cosmetic mass to be applied can be drawn off, as already explained above within the scope of claim 1 to a large extent. However, protection is not only claimed with reference to one of the preceding claims, but also in isolation.

This cosmetic stick according to the invention also includes a cartridge holder for receiving a cartridge that can be replaced without tools.

It is characterized in that the cartridge held ready for application by the cartridge holder protrudes freely from the cartridge holder with its mine-side tip surrounding the cartridge like a jacket, preferably with at least a free length that corresponds to twice the diameter of the cartridge 6 . Such a freely protruding tip can be cleaned of residues of the lead mass adhering to its outside before the cartridge is removed through the cartridge holder with a flick of the wrist.

In this way, the risk is reduced that residues of lead material get into the cartridge holder and soil it when applying make-up or later when changing the cartridge. In addition, such a freely protruding tip can be well covered with a cap when not in use, which seals against the tip in the front area by means of a corresponding sealing element.

In this way, a refillable cosmetic pen is created that can be fitted with different cartridges particularly easily and cleanly, for example to be able to apply make-up with different colors.

A second solution to this further problem according to the invention looks as described by the features of claim 8.

According to the invention, a refillable cosmetic pencil with a refill is proposed, from which the cosmetic mass to be applied can be drawn off—as already explained above in the presentation of claim 1 to a large extent. However, protection is not only claimed with reference to one of the preceding claims, but also in isolation.

This cosmetic stick according to the invention is characterized in that when not in use it is closed by a cap pushed over the cartridge and/or over the cartridge holder.

According to the invention, the cap can be designed in several parts and then consists of at least one cap shaft and a cap head, which can preferably be snapped onto the cap shaft in a form-fitting manner. The cap head is at the same time a mostly cap-like, often one-piece transport closure for the removed, loose cartridge or for the separately delivered refill cartridge.

Ideally, the cap head can be snapped onto the cap shaft by the user without tools and ideally can also be separated from the cap shaft again in the same way. In this way, the applicator according to the invention can also cope with color changes with a single cap shaft, without color mixing occurring. Only the lead of one and the same color protrudes into the front, mostly even narrowing part of the inside of the cap.

Since said problem occurs in particular in the region of the cap head, according to the invention an individually adapted cap head is attached to the cap shaft of the novel cosmetic pencil for each lead.

A second solution to this further problem according to the invention looks as described by the features of claim 20.

This cosmetic stick according to the invention also comprises at least one cartridge holder, preferably two cartridge holders, for receiving one or two cartridges that can be exchanged without tools.

OPTIONAL DESIGN POSSIBILITIES OF THE INVENTION

It has proven particularly favorable if the cartridge has a cartridge plunger as a component part of the cartridge at its end facing the feed mechanism. Typically, the cartridge plunger is discarded along with the cartridge. In normal application operation, the cartridge piston usually runs completely inside the cartridge. About him the feed mechanism can advance the mine. Typically, the cartridge piston seals the cartridge outward on its side.

The cartridge plunger prevents the cartridge content from deteriorating in a cartridge that is traded as a refill unit and is therefore also exposed to a longer storage period. During application operation, the cartridge piston prevents a component of the feed mechanism from coming into direct contact with the cosmetic lead and the cosmetic lead from sticking to the feed mechanism. The latter could cause hygiene problems in the long term and is also problematic if the cosmetic pencil is to be used, for example, with interchangeable cartridges of different colors.

Ideally, the cartridge piston is designed as a flat piston, i.e. as a disc-shaped structure with a thickness in the direction of the feed axis that is only a fraction, often less than ¼ of the mine diameter.

In this way, the length of the cosmetic pencil is reduced, making it much easier to handle. As a result, the cosmetic stick according to the invention is also predestined for fine application work such as lip edging or the precise drawing of an eyeliner.

It has proven to be particularly favorable if the cartridge piston is connected to the mine in such a way that it can also be pulled back into the cartridge, under certain circumstances even completely back into the cartridge. For this purpose, the mine is attached to the cartridge piston in a suitable manner.

In many cases it will be favorable if the cartridge piston has a hollow-cylindrical piston skirt. If required, this can enter into a sufficiently strong, friction-locking connection with the section of the lead inserted into it - for example because the lead is pressed in just as strongly as its consistency allows. In other cases, the mine can also be cast with the cartridge piston. This is an option in particular when the cartridge piston has an anchoring extension for this purpose, which can be embedded in the lead when the lead is cast.

The overall length of the cartridge piston or the flat piston and its piston skirt in the direction of the longitudinal axis is preferably at least one lead diameter and ideally less than three lead diameters.

Preferably, the feed mechanism includes a feed rod. After a fresh cartridge has been inserted, this can be coupled to the cartridge simply by actuating the feed mechanism in such a way that the feed rod moves into the interior of the cartridge by further actuating the feed mechanism at one end of the cartridge. In this way, the feed rod pushes the lead at the other end of the cartridge out of the cartridge into its application-ready position.

The user does not have to intervene at this point, so it is does not require any action by the user on the parts of the feed mechanism inside the applicator or on the area of the cartridge that is already inserted in the cosmetic pencil.

It is particularly favorable if a latching element is attached to the end of the feed rod, in particular in the form of a latching claw. The cartridge piston carries a counter-locking element, in particular in the form of a locking projection. The latching element and the counter-latching element are designed in such a way that they latch with one another by advancing the feed rod in the direction of the cartridge piston. This latching takes place in that the latching element or the counter-latching element, when it has received the counter-latching element or the latching element in it in the course of infeed, is pressed elastically into its closed position by the wall of the cartridge. This is preferably done by means of a closing cone, which ideally interacts with corresponding bevels on the counterpart.

In this way, a coupling is created between the feed rod and the cartridge plunger, which allows both advancement and retraction of the cartridge plunger and the mine connected thereto.

At no time does the user have to worry about the exact workings of the feed mechanism and how the feed mechanism is coupled to the particular cartridge, let alone any manual intervention in the feed mechanism or the clutch. Intervention would be uncomfortable and would ultimately produce rejection in practice.

Ideally, the latching element at the end of the feed rod is a latching claw with at least one, significantly better at least two, latching arms or latching claws. Typically, the latching claw or latching claws are non-detachably coupled to the counter-latching member by retracting the feed rod into the cartridge.

It is particularly favorable if the cartridge holder has a side window. The side window is positioned and dimensioned in such a way that a used cartridge can be removed from the cosmetic pencil or its sample holder through the side window without tools and with bare hands. As a rule, the mine is pulled out in an oblique, non-perpendicular direction to the feed axis.

The side window in the cartridge holder also allows a fresh cartridge to be inserted in the reverse direction. So the mine is pushed in at an angle, again not perpendicular to the feed axis.

The great advantage of such a side window (hereinafter also referred to as an opening) is that the cosmetic pencil does not have to be dismantled in any way to change the cartridge. In contrast to a ballpoint pen, for example, no lower part has to be unscrewed in order to be able to insert a new ballpoint pen refill or cartridge into the upper part and the lower part, which is to be screwed on again in the next step.

It is particularly favorable if the cartridge holder has an end window through which a part of the cartridge ready for use and a part of the mine ready for use protrude beyond the cartridge holder, typically along the feed axis of the mine. Such a construction is particularly advantageous because in the vicinity of the lead, as the length of use increases, the residues of the lead adhering to it increasingly do not reach the area of the cartridge holder. Instead, such residues can be removed together with the old cartridge the next time the cartridge is changed.

Ideally, the cartridge holder has a side window and a front window, hereinafter also referred to as an opening. These are dimensioned to the geometry of the associated cartridge and positioned relative to one another in such a way that the end of a cartridge to be replaced that faces the feed mechanism can be swiveled out of the cartridge holder through the side window in a first step such that said end is completely free. Then, in a second step, the cartridge can be pulled out of the front window and the cartridge holder through the side window. The side window and the front window advantageously form a common opening. This is only made possible by a corresponding play between the cartridge and the cartridge holder. This will not grip the cartridge too tightly. It is also expedient if the end window or its reveal is formed by a ring which is inclined or cut relative to the feed axis and thereby promotes the described pivoting of the cartridge.

In order to be able to easily initiate the pivoting described or to be able to easily release the cartridge locked in its application-ready position for the purpose of changing the cartridge, it has proven to be very useful to provide a smaller side window that is ideally at least approximately diametrically opposite the first side window.

A lateral force initiating the cartridge change can be exerted on the cartridge through this smaller side window. For example, such a lateral force can be exerted on the cartridge to be replaced with a fingernail or a foreign body by exerting pressure on the cartridge to be replaced through the side window perpendicularly or approximately perpendicularly to the feed axis. The part of the cartridge that protrudes into this smaller side window can also be designed as a latching element. As a latching element that helps to hold the cartridge securely in its application-ready position after it has latched into the cartridge holder or its window reveal.

It is particularly favorable if the cartridge holder has an anti-twist device which preferably interacts with the cartridge in a form-fitting manner. This prevents the cartridge from rotating with the attempt to recondition the lead with a sharpener, which would thwart sharpening. With a small lead diameter, the lead is prevented from turning by the sealing element on the piston.

Expediently, the anti-rotation device of the cartridge can be a lateral extension on the cartridge that does not extend over the entire circumference of the cartridge and that interacts with a part of the reveal of the side window in a form-fitting manner. It is particularly useful if the side extension on the cartridge interacts with the portion of the side window reveal positioned forward of the cartridge holder, in close proximity to the end window. In many cases, this lateral extension will also form a longitudinal stop which abuts against said section of the reveal of the side window and prevents the cartridge from being pushed further out of the cartridge holder through the front window.

It is particularly favorable if the cosmetic pencil is closed with a cap until the next application, which is held centered in its closed position solely by the cartridge and preferably also by the cartridge holder.

It is particularly favorable if the cap lies tight against the tip of the cartridge protruding from the end window of the cartridge holder and is radially pretensioned there, ideally in an area that (seen in the direction of the feed axis) is at least an amount away from the outermost end of the tip of the cartridge holder mine away, which corresponds to a single mine diameter and which ideally corresponds to no more than three times the mine diameter. In this way, the tip of the refill lies in a compartment protected from air exchange between said sealing area and the end of the cap. This compartment has only a small inclusion volume. Only a small amount of air is therefore trapped, which can then have a spoiling or quality-reducing effect on the mine, and essentially no air flows into the compartment accommodating the mine. In other cases, the use of volatile components in the lead is made possible in the first place by said sealing in the cap and premature evaporation of such components during longer storage times between individual applications is prevented.

It has proven to be particularly favorable if the cap is designed in several parts. It then consists of at least one cap shaft and one cap top. The cap head can preferably be snapped onto the cap shaft in a form-fitting manner, ideally without tools, by hand. In the same way, the form fit between the cap shaft and the cap head can be released again, preferably without tools. The cap head is also a sealing cap for the removed, loose cartridge and ideally a permanent freshness seal for a replacement cartridge that is delivered separately. This closure also makes it possible to use volatile components in the refills of the replacement cartridges and prevents such components from evaporating prematurely during longer storage times.

Such an embodiment is particularly practical where one and the same cosmetic pencil is to be used in a quick change with different cartridges containing different mines. Because it prevents, for example, when using mines of different colors by putting on the same cap to bridge shorter or longer work breaks, that one mine is contaminated with material from another mine via the cap, so that it, for example, unwanted color mixtures.

It is favorable if the feed mechanism consists of a feed rod with a thread, which is held in the cartridge holder in an axially displaceable but non-rotating manner. For this purpose, the thread is preferably provided with at least one longitudinal flattening or groove, which interacts with the cartridge holder in such a way that security against twisting is achieved. The feed rod with the thread is actuated by a threaded nut, which is preferably completely self-contained in the circumferential direction. Such a threaded nut offers high resistance to thread skipping under high loads. In particular, it withstands increased loads Conditions as they can occur in the context of the invention, for example, when coupling and uncoupling the threaded rod to the cartridge piston according to the invention. In addition, this threaded nut preferably has a sleeve extension, with which the threaded nut is held in a torsion-proof manner by the sleeve forming the handle, which sleeve is rotatably mounted on the cartridge holder. The cartridge piston advantageously seals the cartridge.

Not only is protection claimed for a complete refillable cosmetic applicator loaded with a cartridge, but also protection is claimed for the unloaded refillable cosmetic applicator.

Then protection is also claimed for the associated cartridges on their own. These cartridges can have different configurations. Ideally they will have one or more physical features as previously described in the other claims and/or the specification for the cartridge. In accordance with patent law, a claim for use will also be asserted in due course.

Further design options, advantages and modes of operation result from the following exemplary embodiments, which are described with reference to the figures.

EXEMPLARY EMBODIMENTS

The 1A until 1C show an exemplary embodiment of the refillable cosmetic stick 1 according to the invention. The handpiece in the form of the gripping sleeve 2 (also referred to as sleeve), which carries the cartridge holder 3, which can hardly be seen here, is clearly visible. Also clearly visible is the cap 4, which closes the pen 1, which is otherwise equipped with a ready-to-use refill.

The cartridge holder 3 is also clearly visible here. It accommodates a cartridge 5 .

In the cartridge 5 a mine 6 is performed. The mine 6 is usually solid and consists in any case of the cosmetic to be applied. The mine will typically be designed in such a way that a specific quantity of the cosmetic to be applied can be drawn off from it when the tip 7 of the mine 6 is stroked over the skin area to be treated. It is noteworthy that the mine 6 is only in direct contact with the cartridge 5 over a smaller part of its length, which in 2A is easy to see. An intimate contact is given in the area of the tip 7 of the mine 6 at the end of the cartridge 5 there, because the cartridge is at least substantially tightly in contact with the mine 6 there. A further intimate contact is then preferably given only in the area of the cartridge piston (not shown in the figures). The cartridge piston is preferably firmly connected to the end of the mine 6 facing away from the tip 7 of the mine 6, usually in such a way that the cartridge piston can not only exert pressure on the mine 6, but also, if necessary, tension.

In the area between the cartridge piston and the seal described in the area of The tip of the mine 6 does not lie against the cartridge 5 from the inside. In this way, easy displaceability of the mine in the direction of the feed axis M is ensured, which prevents large-area sticking between the lateral surface of the mine 6 and the inner surface of the cartridge 5, which would impede the function. Typically, the cartridge piston seals against the interior surface of the cartridge 5. In this way, the drying out or outgassing or spoilage of the lead 6 is effectively counteracted, even if the cartridge 5 is kept in stock for a long time before it is put into circulation. For this purpose, the piston skirt of the cartridge piston in particular may be provided with the necessary oversize and possibly also a reduced wall thickness, so that it nestles tightly against the inner surface of the cartridge 5 in an elastically resilient manner.

As in the 1A until 1C and 4 As can be clearly seen, the sleeve forming the handle 2 typically houses the majority of the translation mechanism 70 (also referred to as the feed mechanism in this specification). The displacement mechanism 70 consists here of the feed rod provided with an external thread. This is actuated by a threaded sleeve with a matching internal thread. The threaded sleeve is preferably self-contained in the circumferential direction, not slotted, in any case not continuous. In this way, skipping of the thread is ruled out, even when greater forces have to be applied, for example for coupling or decoupling, as will be explained in more detail immediately.

The threaded sleeve is, as a rule, fixed directly in the sleeve forming the handle 2 .

The threaded sleeve 9 is preferably provided with an anti-twist device, with the aid of which it is held by the sleeve forming the handle 2 so that it cannot turn. At the same time, it is usually fixed in a form-fitting manner on the cartridge holder 3 by means of a latch, at least in the axial direction.

Optimally, the thread of the feed rod is not a continuous thread groove, but only attached to two diametrically opposite sides of the feed rod. In this way, lateral flat areas can be provided on the feed rod. These interact with the cartridge holder 3 in such a way that the feed rod can be displaced longitudinally in the cartridge holder 3, but is held by it in a non-rotatable manner.

In the 1A until 2D it can be seen that the sleeve forming the handle 2 is rotatably held by the cartridge holder 3, in the present exemplary embodiment in that a part of the cartridge holder is pushed inside into the sleeve forming the handle 2 and is preferably latched there.

The end of the feed rod is equipped with a locking element, which here has the shape of a locking claw. In this specific case, the latching claw has two claw elements. These claw elements each have an elastically resilient shaft. Their basic position, which they assume in an unforced state, can be defined as the "open position".

The cartridge piston is advantageously equipped at its external front end with a counter-locking element in the form of a locking projection that can be gripped behind.

In the "open position" just described, the claw elements can slide freely or essentially freely over the locking projection of the piston and receive the piston between them.

When corresponding forces occur, the claw elements can be pressed in an elastically resilient manner in the radially inward direction by deformation of the flexible shaft of the locking claw holding them.

A closing cone, which the cartridge has at its end opening facing the feed rod, is responsible for the application of such forces. Ideally, the claw elements each have a complementary bevel on the outside. As soon as these come into contact with the locking cone and the feed rod is moved even further in the direction of the cartridge piston, the locking cone presses the claw elements in a radially inward direction so that they clasp the latching projection in a form-fitting manner. As soon as the claw elements have closed completely and the feed rod still continues to move towards the cartridge 5, the feed rod with its claw elements and the cartridge piston move together into the cartridge in order to push out the mine at the other end. As long as the cartridge plunger is moved into the cartridge, the inner surface holds the claw elements in their closed position, so that a firm connection is now created between the cartridge plunger and the claw elements in both feed directions. This means that the mine can not only be extended out of the cartridge by moving the feed rod accordingly, but also retracted into it. The claw elements can only be pulled off the locking projection of the cartridge piston again when the cartridge piston comes to rest again with its locking projection in the area of the locking cone.

This coupling does not require any direct manual action on the part of the user on the feed rod and/or the cartridge 5. At the same time, your own fingers will not get dirty when coupling the cartridge 5.

Based on 3A until 3D it is also easy to see how the cap 4 can sit on the cartridge holder 3 and the cartridge 5. The cap has a seal or a sealing projection internally. When the cap 4 is in the closed position, this sealing projection lies essentially airtight directly against the cartridge 5, preferably in the region of the tip 7 of the mine 6 Compartments, with reduced volume, are kept airtight in a small space, often representing less than one-fifteenth of the internal space enclosed by the cap 4. The tip 7 of the lead 6 is thus well protected against drying out and no appreciable outgassing of ingredients from the lead can take place. Because if something diffuses out in gaseous form, then the small volume of the compartment within which the tip 7 is stored is quickly saturated with the substance that has diffused out. As a result, there is no concentration gradient that would drive further diffusion.

The cartridge 5 is secured against rotation relative to the cartridge holder 3 . The cartridge 5 is here provided with a laterally projecting projection (not shown) which projects into a recess (not shown) provided in the cartridge holder 3.

More details about the cartridge holder 3 can be well based on the 1A until 1C remove.

The cartridge holder 3 consists of a tubular part that protrudes freely from the sleeve forming the handle 2 when the cap 4 is removed, also referred to below as the cartridge holder body 30 . This tubular part 30 is ideally essentially cylindrical. The tubular part or the cartridge holder body 30 is designed, dimensioned and matched to the cartridge 5 in such a way that a used cartridge 5 can be removed and a new or different cartridge 5 can be reinserted.

The cartridge holder body 30 has two side portions 33 (hereinafter also referred to as cartridge holder body side portions), a cartridge holder body beginning portion 31, a cartridge holder body end portion 33, and a cartridge holder body recess 34. As shown in FIG.

As already mentioned, the cartridge holder body 30 is preferably cylindrical, but it can also be triangular, square or polygonal, for example, according to the shape of the pen. Oval or polygonal (also referred to herein as polygon) shapes of the cartridge holder body 30 are also advantageous. The shape of the cartridge holder body 30
but can also be different than the shape of the holding piece (2) or the cosmetic pencil 1. In particular, the shape of the internal cavity for accommodating the cartridge 5 may be different from the shape of the outer surface of the cartridge holder body 30. For example, the shape of the internal cavity for accommodating the cartridge 5 may have a triangular, square, polygonal, oval or polygonal shape while the shape of the outer surface of the cartridge holder body 30 is round.

The cartridge holder body end portion 32 is as in FIG 1A particularly easy to see, round chamfered or has a rounding, starting from the front (at the tip 32 of the cartridge holder body 30) to the cartridge holder body side sections 33, which run parallel to the center line M or axis line of the cosmetic pencil 1. Toward the end, the cartridge holder body 30 has a recess 34 (hereinafter also referred to as cartridge holder body recess). The cartridge holder body recess 34 is preferably a circular recess and terminates at the opposite end of the cartridge holder body 30 at the cartridge holder body beginning portion 31 (with respect to the tip or cartridge holder body end portion 32).

As already mentioned, the cartridge holder body recess 34 is preferably round, but can also be triangular, square or polygonal, for example, corresponding to the shape of the pen. Oval or polygonal shapes of the cartridge holder body 30 are also advantageous. The shape of the cartridge holder body recess 34 corresponds to the shape of the cartridge case projection 51 . Particularly preferably, the shape of the cartridge holder body recess 34 and the shape of the cartridge case projection 51 are form-fitting to one another. The cartridge case projection 51 is explained in more detail below.

The cartridge holder body 30 has two cartridge holder body side portions 33, in which the cartridge 5 is inserted or clicked into the cartridge holder 3 without tools (hereinafter also referred to as a denoted in bold). The open space between the cartridge holder body side portions 33 is also referred to as an opening (also referred to as a window in the specification) hereinafter or in this specification and/or claims. The cartridge holder body side sections 33 are particularly preferably designed to be elastic and/or resilient. The cartridge holder body 30 is preferably made of a plastic material or a thin metal or sheet metal or metal foil.

As in the 1B , 2D and 4 As can be seen, the cartridge holder body 30 has an opening formed laterally by the two cartridge holder body side portions 33 . Furthermore, the opening (also referred to as a window in the description) is formed by the cartridge holder body beginning section 31 and the cartridge holder body end section 32, so that the cartridge 5 is inserted or removed from above or from the front through the opening in the cartridge holder 3 (and thus in the cartridge holder body 30). .can be clicked in.

As well as in the 1A until 1C As can be seen, the feed mechanism 70 is attached to the rear part in the area of the cartridge holder body beginning section 31 .

Through the opening in the cartridge holder body 30, the cartridge 5 can be clicked or latched into the cartridge holder body 30 by pressure from above. Here, the cartridge case 50 preferably snaps into place between the two cartridge holder body side sections 33 . This is preferably done by the springy and/or elastic design of the cartridge holder body side sections 33, so that the cartridge case 50 is held by the cartridge holder 3 in an elastically resilient manner.

When the cartridge 5 latches or clicks in place, the cartridge holder 3 or the cartridge holding body 30 accommodates the cartridge 5 in a form-fitting and/or force-fitting manner and/or by frictional adhesion.

Alternatively, the cartridge 5 can have a connecting section 51 which connects the cartridge 5 in a positive and/or non-positive manner to the handpiece 2 or to the cartridge holder body 30 and thereby to the cartridge holder 3 .

As in 2A As can be seen, pressure can be exerted on the front section of the cartridge 5 with a finger or a pointed object, as a result of which the cartridge 5 is unlocked from its ready-to-use position, in which it is held in a form-fitting and/or force-fitting manner and/or by frictional adhesion in the cartridge holder 3 was locked so that it can be removed from the cosmetic pen 1 or the cartridge holder 3. When pressure is applied to the front end or portion of the cartridge 5, the cartridge 5 is pivoted out of its ready-to-use position so that this end of the cartridge 5 is no longer (at least partially) engaged with the cartridge holder 3.

This pivoting movement allows the cartridge to be seated in the cartridge holder 3 on the side of its tip with adequate play. This game allows the cartridge 5 to perform the required pivoting movement in the area of its tip. A chamfer or an oblique section of the cartridge holder 3 can contribute to this.

The cartridge 5 can now be pulled completely out of the cartridge holder 3 or cartridge holder body 30 through the opening (also referred to herein as a side window or front window) until it finally comes completely free and is then removed. A new or different cartridge 5 is reinstalled in the reverse order or by pressing or clicking in between the resilient, elastic cartridge holder body side sections 33.

The cartridge 5, which is provided here with a protective cap that serves as a transport lock for the mine 6 and is deducted and discarded before inserting the cartridge 5 into the cartridge holder 3. In some cases the protective cap will be designed and tied to the cartridge 5 to form a seal which will be broken after first opening. In this way, a real seal closure is guaranteed.

The cartridge 5, which contains the refill 6, is preferably substantially cylindrical on the outside. The cartridge 5 is as in the 2A until 2D received in cartridge holder body 30 as shown. As already mentioned, the shape of the cartridge 5 is preferably essentially (at least partially) cylindrical, but can also be triangular, square or polygonal, for example corresponding to the shape of the pen, since such shapes are easy to hold in the hand or with the fingers can become. Oval or polygonal shapes of the cartridge 5 are also advantageous since they are easier to grip and hold with the fingers. However, the external shape of the cartridge 5 may be different from the shape of the holder 2 or the cosmetic stick 1. In particular, the shape of the cartridge 5 can be at least partially different from the shape of the holder 2 or the cosmetic pencil 1. For example, the shape of the cartridge 5 can have a triangular, square, polygonal, oval or polygonal shape, while the shape of the holder 2 or of the cosmetic pencil 1 is round.

Furthermore, the shape of the internal cavity of the cartridge holder body 30 for accommodating the cartridge 5 may be at least partially different from the shape of the outer surface of the cartridge 5. For example, the shape of the internal cavity for accommodating the cartridge 5 may have a round, cylindrical shape, while the shape of the Cartridge 5 is triangular or polygonal.

The cartridge 5 is preferably made of a plastic material. since the cartridge 5 can be manufactured particularly easily and is also light. However, the cartridge 5 can advantageously also consist of a thin metal or sheet metal or a metal foil, since this material can be held and/or gripped particularly well by the hand or the fingers. In particular, the cartridge 5 is made of glass if, for example, a particularly stable cartridge is required.

As in the 1A until 1C As shown, the cartridge 5 includes a cartridge case 50, a front cartridge case portion 52, and a cartridge case end portion 53. FIG. The cartridge 5 further preferably optionally has a cartridge case projection 51 which is arranged on the cartridge case 50 . Advantageously, the cartridge case projection 51 is attached to the rear end of the cartridge case 50, on the side on which the displacement mechanism or feed mechanism 70 is located when the cartridge 5 is in its position in the pen 1, ready for use.

The cartridge case 50 advantageously nestles against the reveal or (inner) surface of the cartridge holder body side sections 33 of the cartridge holder body 30 from the inside, so that a positive or non-positive connection or a connection due to friction is created.

Also good based on the 1A until 1C it can be seen that the cartridge case projection 51 of the cartridge 5 is attached to the rear end of the cartridge case 50 . The cartridge 5 can preferably be clicked or latched into the cartridge holder body 30 by pressure from above or from the front. Here, the cartridge case projection 51 preferably snaps into the cartridge holder recess 34 . This is preferably done by the resilient and/or elastic design of the cartridge case projection 51 and/or the cartridge case projection 51. By clicking or latching the cartridge case projection 51 into the cartridge holder recess 34, a positive or non-positive connection is created between the cartridge case projection 51 and the cartridge case projection 34. When the cartridge 5 latches or clicks in place, the cartridge holder 3 or the cartridge holding body 30 accommodates the cartridge 5 in a form-fitting and/or force-fitting manner and/or by frictional adhesion.

How particularly good in 2C As can be seen, the connecting portion 51 is arranged or formed or formed on the outside of the cartridge case 50 . The connecting section 51 is advantageously formed in one piece with the cartridge case 50, preferably as a projection.
The handpiece 2 is formed by a sleeve and the connecting section 51 advantageously engages over the thickness of the sleeve, and particularly preferably on the outside of the sleeve, in a form-fitting and/or non-positive manner.

How particularly good at that 1A until 2D , 4 and 5 As can be seen, the outer diameter of the cartridge case tip section 53 decreases towards the end of the cartridge case 5 (towards the mine tip 7).

Particularly advantageously, the connecting section 51 or the cartridge case projection 51 protrudes beyond the cartridge case 50 in the direction of the grip (grip sleeve or handpiece) 2, as shown in 1C you can see.
In a further advantageous manner, the connecting section 51 or the cartridge case projection 51 protrudes beyond the cartridge case 50 in the radial direction (i.e. perpendicular to the central axis M), as is also shown in 1C you can see.

As in the 2A until 3D is shown, the connecting section 51 or the cartridge case projection 51 is flush with the outer surface of the cartridge holder 3 or cartridge holder body 30 in the installed and/or ready-to-use state in the radial direction and/or in the axial direction.

In order to achieve the positive and/or non-positive engagement, the outside diameter of the cartridge case front section 52 is preferably the same size as or more preferably smaller than the outside diameter of the cartridge case end section, with the cartridge case 50 having the cartridge case front section 52 and a cartridge case end section on which the connecting section 51 is arranged the cartridge case front portion 52 opposite. In a particularly advantageous manner, the outside diameter of the cartridge case end section is the same size as or preferably slightly larger than the inside diameter of the cartridge holder body 30. Frictional adhesion is thus also increased or produced.

The cartridge case projection 51 is as in FIGS 2C and 3C shown in the radial direction slightly smaller than half the height of the pen 1 and the cartridge holder body 3. Preferred is the The height of the cartridge case projection 51 is approximately 1/5 or 1/3 of the height of the pin 1 or the cartridge holder body 3. In particular, the height can be exactly half or greater than half the pin 1 or the cartridge holder body 3. Here would be a height of the cartridge case projection 51 at about 2/3 or 4/5 of the height of the pin 1 or the cartridge holder body 3 should be mentioned as advantageous.

As in the 1B and 1C can be seen, the cartridge case projection 51 protrudes somewhat in the axial direction. In particular, the cartridge case projection 51 protrudes in the axial direction over the cartridge case 50 by approximately the thickness (+/-10% or +/-20% of the thickness are also advantageous) of the cartridge holder body 30 or cartridge holder 3.
The length of the cartridge case projection 51 in the axial direction corresponds to slightly less than half the length of the cartridge case 50. A length in the range of 30% to 60% of the length of the cartridge case 50 is also advantageous. In other words, the advantageous length of the cartridge case projection 51 is in the axial direction Direction at 1/6 to ¼ of the length of cartridge holder body 30 or cartridge holder 3.

As can be clearly seen in all figures, the shape of the projection 51 is U-shaped. The shape of the projection 51 is advantageously adapted to the shape of the grip 2 or the cartridge holder body 30 or cartridge holder 3 . The shape of the projection 51 can also be V-shaped or have an oval or polygonal shape.

The refillable cosmetic stick or stick according to the invention further has a cap or protective cap 4 to close the cosmetic stick or stick 1 . For example, the lead can be protected from drying out. The cap 4 in the is particularly good 1 until 4 shown.

The cap 4 is essentially cylindrical and closed at one end. The cap 4 accommodates the cartridge 5 together with the mine 6 (at least partially) and forms a positive fit with the cartridge holder body 30 or cartridge holder 3 . The cap 4 advantageously closes the cartridge 5 and the cartridge holder body 30 or cartridge holder 3 in a form-fitting manner when the cartridge 5 is inserted or clicked into the cartridge holder 3 .

The cap 4 advantageously has a cap tab 40 , a cap tab end 41 , a cap tab beginning 42 , a cap tab side 43 and a cap tab transition 44 .

The cap projection 40 advantageously closes the cartridge holder 3 or the cartridge holder body 30 in a form-fitting manner. Advantageously, the cap projection 40 is flat, with the cap projection 40 being thinner than half the diameter of the cosmetic pencil or stick 1. The height or diameter (or partial diameter) of the cap projection 40 is approximately ¼ the height (in the radial direction) of the cartridge holder body 30 or cartridge holder 3. The length of the cap boss 40 is about half the length of the cartridge 5, but preferably less than half the length of the cartridge 5. In other words, the length of the cap boss 40 is about 1/3 to 1/2 the length ( in axial direction) of cap 4.

Basically, the cap projection end 41 is formed to conform or correspond to the shape of the cartridge case projection 51 so as to form a close fit. The cap projection end 41 is advantageously round.

The cap projection side 43 is formed to conform in shape to the cartridge holder body side portion 33 so as to be form-fitting.

Further advantageously, the cap projection transition 44 and the cap projection beginning 42 are designed in such a way that they match or correspond to the shape of the cartridge holder body end section 32 in order to thus close in a form-fitting manner. The beginning of the cap projection 42 is advantageously round or circular (at least partially) in the radial direction. In particular, however, the cap projection beginning 42 has the shape of the cartridge holder body end portion 32 in the radial direction. Further advantageously, the beginning of the cap projection 42 is designed to be elastic and/or spring-loaded, so that it can be closed in a form-fitting and/or non-positive manner or by frictional adhesion, as is the case, for example, in FIGS 3A until 3D is shown.

At the other end or on the opposite side of the cap 4 the cosmetic stick 1 is closed. The grip or handpiece 2 is advantageously closed or closed off by a cover that can be removed and put on again or by an end cap 9 that can be removed and put on again. Alternatively, this is done by means of a screwable (i.e. screwable and unscrewable) cover or a screwable or screwable and unscrewable end cap 9. The cover or the end cap 9 is preferably made of the same or the same material as the handle or the handle 2. The cover is preferably made of plastic, metal and/or glass.
The 4 shows a second embodiment of the refillable cosmetic stick according to the invention 1.

This second exemplary embodiment differs from the first exemplary embodiment just described only in that the cosmetic pencil or pencil 1 is designed somewhat differently at its rear end. Otherwise, what was said above applies accordingly, even if it is not repeated again.

like it in 4 As can be seen, the cosmetic stick or stick 1 according to the invention has an end piece 8 and optionally a lid or end cap 9 at the rear end (on the opposite side of the refill tip 7 or the cap 4). The end piece 8 is on or in the handle 2 or

Handpiece 2 arranged, wherein it is preferably (at least partially) housed within the handle 2 or handpiece 2. The end piece 8 is advantageously arranged on the one hand in the handle 2 and on the other half outside of the handle 2 . With regard to the various alternative uses of the end piece 8 according to the invention, as explained in more detail below, the proportion or the length of the end piece 8 in the handle 2 and the length or the proportion of the end piece 8 in the lid or the end cap 9 different, whereby a larger portion of the end piece 8 can preferably be contained in the grip 2 than in the lid or the end cap 9. A ratio of the length of the end piece 8 in the lid or the end cap 9 to the length of the end piece 8 in the grip 2 is particularly advantageous in the range of about 1:6 to 1:1. Thus, ratios of about 1/5, ¼, 1/3, but also ½ are particularly advantageous. Furthermore, the end piece 8 has at least a portion of the same shape as the grip or the outer surface of the grip 2. Advantageously, both a part of the grip 2 and a part of the end piece 8 are essentially cylindrical. The lid or end cap 9 is open (orifice) on one side and closed on the other side.

The end piece 8 can be accommodated in the end cap 9 through the opening in the cover or the end cap 9 . The end cap 9 is advantageously snapped into the end piece 8 by pressure from above (along the longitudinal axis of the pen 1 and in the direction of the lead tip 7) so that the end cap 9 is held by the end piece 8 in an elastically resilient manner. This is preferably done by making the end cap 9 resilient and/or elastic at its open end. Alternatively, this can also be done by a screw connection. By clicking or snapping the end cap 9 into or onto the end piece 8, a positive or non-positive connection is created between the end cap 9 and the end piece 8. When the end cap 9 snaps or clicks in, the end cap 9 takes the end piece 8 in itself ( at least partially) in a positive and/or non-positive manner and/or by frictional adhesion.

As previously explained, the cosmetic stick or stick 1 can be closed by the lid or end cap 9 , the lid or end cap 9 closing the end piece 8 here. The end piece 8 is advantageously closed or closed off by a cover that can be removed and put on again, or an end cap 9 that can be removed and put on again. Alternatively, this is done by means of a screwable (ie screwable and unscrewable) cover or a screwable or screwable and unscrewable end cap 9. The cover or the end cap 9 is preferably made of the same or the same material as the handle or the handle 2 and /or the end piece 8. The cover is preferably made of plastic, metal and/or glass. The cover or the end cap 9 preferably has an opening in which at least part of the end piece 8 can be accommodated. The end piece 8 is thus accommodated and closed by the handle piece 2 and the cover or the end cap 9 . The end piece 8 is advantageously at least partially arranged between the handle 2 and the cover or the end cap 9, as shown in 4 is shown. The end piece 8 is also advantageously arranged centrally (in the axial direction) on the center line between the handle 2 and the cover or the end cap 9, as is also shown in 4 is shown.

The end piece 8 can, for example, have a sponge for spreading the applied cosmetic compound, compound or paint. Alternatively, the end piece 8 can have an eraser or removal means for erasing or removing the applied or applied cosmetic compound, compound or color. The end piece 8 can advantageously be formed by a further (second) cartridge holder 3, so that the cosmetic pencil or pencil 1 can contain two cartridges 5, each with a refill 6. The further or second, which is clicked or engaged in the further or second cartridge holder 3, is ready for use or ready for application as soon as the cover or the end cap 9 is removed or removed. The grip 2 or handpiece 2 has a cartridge holder 3 on both sides (in the axial direction or in the direction of the center line M) with cartridges 5 that are optionally clicked or latched in and optionally advantageously different cartridges. Thus, for example, two different colors or cosmetic masses or masses can be used or applied with one cosmetic pencil or pencil 1.
In a particularly advantageous manner, the end piece 8 can have or contain a sharpener for sharpening the lead 6 which is arranged on the other side of the cosmetic pencil 1 .

The special structure of the end piece 8 used here is particularly based on the 4 clearly visible.

The end piece 8 can be accommodated in the handle 2 through the opening in the handle 2 . The end piece 8 is advantageously snapped into the grip 2 by pressure from above (along the longitudinal axis of the pen 1 and in the direction of the lead tip 7) so that the end piece 8 is held by the end piece 8 in an elastically resilient manner. This is preferably done by a resilient and / or elastic design of the handle at its open end. Alternatively, this can also be done by a screw connection. By clicking or snapping the end piece 8 into or onto the grip 2, a positive or non-positive connection is created between the grip or hand piece 2 and the end piece 8. When the end piece 8 snaps or clicks in, the grip 2 takes the end piece 8 in itself (at least partially) positively and/or non-positively and/or by frictional adhesion.

As previously explained, the cosmetic stick or stick 1 can be closed by the lid or end cap 9 , the lid or end cap 9 closing the end piece 8 here.

The shape (cross-sectional shape or outer cross-sectional shape) of the end piece 8 is advantageously identical to the shape (cross-sectional shape or outer cross-sectional shape) of the handle 2 and/or the end cap 9. Alternatively, the shape of the end piece 8 can differ from the shape of the handle 2 and/or the End cap 9 deviate. For example, the cosmetic stick 1 can have a triangular, square and/or polygonal shape, the end piece can have a round shape and/or the end cap 9 can have an oval shape.

The handle 2, the end piece 8 and/or the end cap 9 are advantageously made of plastic, stone, metal and/or glass.

The 5 shows a cosmetic pen 1 or pen 1 with a cartridge 5 that is ready for use or clicked in. As clearly shown in FIG 5 can be seen, the refill 6 (in the axial direction) is further out of the cartridge. This may be effected by an alternative lead shape or different lead lengths in the cartridge 5, or by simply sharpening the lead with a sharpener such as one housed in the end piece 8.

The cartridge 5 in the removed state is usually also traded as a refill part. That is why a cartridge is explicitly claimed here in isolation. Advantageously, the cartridge 5 for the above-described cosmetic pencil or pencil 1 only has or houses a refill 6, further comprises a cartridge case 50 in which the refill is housed, and is in the cartridge holder 3 of the handle 2 can be inserted or clicked in or snapped in. All, only one or combinations of the features of the cartridge described above can be included in the claimed cartridge 5. The cartridge 5 is again provided with a protective cap. What has been said above largely applies to this protective cap. Its configuration differs from that described above, which is why it is not discarded after the cartridge 5 has been opened.

Instead, the protective cap is designed here in such a way that it is made part of the cap 4 after the cartridge 5 has been opened. For this purpose, the cap 4 consists of a mostly cylindrical cap shaft. This cap shaft also has an open end on its side facing the tip 7 of the mine 6 . The protective cap is connected to this open end and then forms the cap head, which protects the mine 6 when the cap 4 is closed.

The protective cap is preferably pushed into the open end of the cap shaft and then usually latched there. The protective cap has a latching projection for this purpose. This engages in a corresponding latching recess or another latching element of the cap shaft. This latching connection is preferably designed in such a way that the user has the option of removing the protective cap from the cap shaft again without tools, with bare hands, and replacing it with a different protective cap.

This possibility is important if, for example, cartridges with different colors are to be inserted and used in succession. In this way it can be ensured that, for example, a cartridge with a red lead does not suffer from contamination by putting on a cap with which a corresponding cartridge with a blue lead was previously covered.

It is particularly expedient if a removal aid is provided between the protective cap and the cap shaft.

This removal aid is implemented, for example, in the form of a wavy projection on the protective cap. A complementary undulating protrusion is provided on the cap stem. When the protective cap is twisted with the necessary force in relation to the cap shaft, said wave-shaped projections at least partially slide off one another. This creates a significant separating force on the protective cap generated in an outward direction. With their help, the protective cap can be easily released from its latching with the cap shaft. This applies above all when the latching element of the protective cap is seated on an apron or cylinder apron that can be combined in the radially inward direction.
