Description

The invention relates to a cleaning device for manual cleaning of a target surface, comprising a textile cleaning element that can be slipped onto a carrier and / or slipped onto the carrier, with a cleaning section made of a knitted fabric that occupies at least part of the outer surface of the cleaning element and has a basic mesh structure formed from a basic thread. In addition, the invention relates to a method for producing a cleaning element of such a cleaning device.

In the prior art, there is an increasing need for cleaning devices in order, for example, to be able to simply and effectively clean hard-to-reach target areas. In this context, cleaning elements made of textile materials that can be slipped onto a carrier have already been proposed, in particular designed as finger cots to be pulled over a finger. In this case a finger forms the carrier (not belonging to the cleaning device). Finger cots are particularly suitable for cleaning teeth, for example on babies or animals.

Finger cots as pull-on cleaning elements have already been proposed in the prior art. For example, reveals DE 20 2008 010 776 U1 a finger cot, also for use as a work tool, which consists of a flexible and tube-like structure that essentially adapts to the anatomy of a finger and extends from the third phalanx of the fingertip to at least the second phalanx. DE 20 2016 102 041 U1 relates to a device for cleaning and / or care of a wound or for cleaning and / or care of the oral cavity and pharynx, a cap part being included as a finger cot which can be placed on a finger of a hand and which has a head part having villi at its distal end. These villi should be able to achieve a more effective and lasting cleaning and / or care of the oral cavity and pharynx. The villi serve in particular for wetting the tissue structure and / or for cleaning and / or scraping off debridement and act like a so-called feudel.

EP 1 267 663 B1 relates to a finger cot which should consist of a non-woven basic structure, therefore in particular a fleece. The finger cot can have an abrasive surface to simplify cleaning measures, which surface can consist of various textured materials, for example looped bristles on a fleece-like base structure.

DE 102 15 805 C1 discloses a tooth cleaning part which can be applied with elastic deformation on a finger or a holder. The tooth cleaning part comprises an elastic base layer and a pile layer knitted with this, which can consist of microfiber material.
The surfaces of known finger cots or generally known cleaning devices with a cleaning element that can be turned on are usually optimized for certain activities, for example when the finger cot is made from micro-yarns or super-micro-yarns to polish a surface, as is often used in the dental care of babies. If, however, more sustainable cleaning is to be achieved, a cleaning device with an abrasive surface can, for example, first be used in order to then change the cleaning element and then carry out a polish. This is extremely cumbersome. With regard to a more abrasive effect of cleaning sections on finger cots or other cleaning elements, there is also the problem of difficult and expensive manufacturability.
The invention is based on the object of specifying a flexible, in particular multiple work steps in a cleaning device with a robust, simple and inexpensive to manufacture cleaning element, in particular a finger cot.

To achieve this object, it is provided according to the invention in a cleaning device of the type mentioned at the outset that the cleaning section has a first thread, which is designed as a microfibres or super microfibres, and over the basic mesh structure forms protruding first loops, and a second thread, which has a stronger abrasive effect than the first thread and forms second loops protruding over the first loops formed from the first thread, is formed.

According to the invention, it is proposed to use a robust knitted fabric from whose basic mesh structure the first loops of a first thread, namely a microfiber or super microfiber, protrude so that a polishing effect is created and, in particular with a multifilament thread as the first thread, an excellent absorption force for cleaning agents and / or detached dirt is given. The loops formed from the first thread can therefore be referred to as a type of "pile". At the same time, however, the cleaning section of the cleaning element has second loops protruding beyond the basic mesh structure and the first loops and comprising a second thread which has a stronger abrasive effect than the first thread (and the basic mesh structure). In other words, it is proposed to provide a knitted fabric as the cleaning section, via which both the advantageous effect of micro-threads or super-micro-threads can be achieved, but at the same time an excellent (abrasive) cleaning effect is given by the second loops protruding over the first loops. The second loops thus provide a type of “toothbrush effect / grinding effect” and can, preferably together with the first loops, be produced by special stitch-forming processes that will be explained in more detail below.

The loop heads of the second loops made of abrasive threads therefore have a particularly abrasive / emery effect, whereas the micro yarns or super micro yarns of the first loops have a cleaning / polishing effect and can "buffer" agents, in particular cleaning agents, polishes or the like . As a result of the described construction of the cleaning section of the cleaning element, in particular the combination of microfibres or super microfibres and second loops with abrasive second threads in a knitted fabric, that are to be cleaned Surfaces sanded / cleaned and polished / plastered at the same time. The first thread takes up active agents, in particular cleaning agents and / or polishes, and releases them gradually, in particular also to the loop heads of the second loops, whereby the use of the corresponding active agent can be minimized. By carrying out several work steps at the same time, the time required for cleaning is considerably reduced compared to cleaning with conventional finger cots or cloths.

The cleaning device with the cleaning element preferably designed as a finger cot can be used in a wide variety of areas of application, for which different materials / overall properties can be used in order to achieve the cleaning and cleaning / polishing effects required for the specific application. For example, the proposed cleaning device can be used in the sanitary area, for example for cleaning joints, in the two-wheeler area, for example for cleaning rims, spokes, chrome and aluminum parts on bicycles and / or motorcycles, and / or for cleaning other hard-to-reach places, for example in pipes. Further areas of application include, for example, the cleaning of more robust teeth, for example animal teeth, and / or the use as a tongue cleaner, in which case the cleaning device preferably also has the associated carrier, which can be in the form of a spoon and / or scraper, in addition to the cleaning element. That means, generally speaking, the cleaning device can also have the carrier for the cleaning element in addition to the cleaning element.

Specifically, it can be provided that the first thread has a filament titer less than 2 dtex and the second thread has a titer / filament titer greater than 20 dtex, as is customary in relation to the individual filaments in multifilament threads. Multifilament threads with a filament unit below 1 dtex are usually referred to as microfibres (or micro-yarns). If the titer of the individual filaments is in the range of less than 0.7 dtex, and consequently the weight is only below 0.7 g / 10,000 m, one speaks of super microfibres or super micro yarns.

The basic thread can correspond to the first thread, so that the basic mesh structure can also participate in the polishing / buffering effect. In particular, the base thread can also be designed as a microfiber or a super microfiber. In general, however, any thread that can be used for a basic mesh structure can be used as the basic thread.

The cleaning device according to the invention has a cleaning element, in particular a finger cot, in which, at least in one cleaning section, the preferably elastic knitted fabric consists of two or more different threads which have different abrasive effects in addition to the basic mesh structure. In a specific embodiment of the present invention it can be provided that the second loops have an abrasion behavior that is at least 30%, preferably at least 100%, stronger than the first thread. Depending on the application, different ratios of the abrasive effect can be used.

The Martindale method can be used to quantify an abrasive effect in order to be able to check the values mentioned here. The material to be tested is rubbed on a test object on another object, for example with 50,000 cycles / friction units. During this check, the test item records the abrasion that occurs. If the test specimen is weighed before and after the test, the weight difference describes the abrasive effect, which can easily be expressed, for example, in the form of percentage values. For this purpose, for example, a finger cot without abrasive second threads can be tested first, then a finger cot with a second thread. After the test, the amount of abrasion that the test item has absorbed is determined. By comparing the respective abrasions, a difference in abrasion can be determined in percent.

The particular advantages of using knitwear are particularly evident in embodiments in which the cleaning element is made entirely of knitwear and / or is elastic. Especially with a elastic design of a cleaning element designed as a finger cot, this can be easily and conveniently pulled onto a corresponding finger and adapts to the finger geometry. The finger can then be used as a carrier for the cleaning element in order to clean the at least one target area by means of the cleaning section. The elasticity is preferably brought about by elastic threads, whereby either the basic thread and / or the first and / or the second thread itself can be provided with a certain elasticity, or, as will be explained in more detail below, the elasticity providing Additional threads can be used in the respective stitches.

The use of a knitted fabric also offers further advantages within the scope of the invention. A more economical and simpler production of the cleaning element is thus possible. The cleaning section, or, if the cleaning element is preferably completely formed from knitted fabric, the entire cleaning element, is more stable than, for example, when using nonwovens and can also be made more elastic. Furthermore, the knitted fabric does not require a seam, which is particularly advantageous with regard to finger cots as cleaning elements, since there are no disturbing edges / bulges and the finger cot rests softly and smoothly on the finger. A complete cleaning element, in particular a complete finger cot, comprising, for example, a hose-like structure closed on one side by a cap, is completely knitted, for example by a knitting machine, which enables simple manufacture.

Due to the robust design, the cleaning element can be washed and reused multiple times, for example more than thirty times.

As already mentioned, due to the different conceivable areas of application, different materials are also conceivable for the first and the second thread and, if necessary, additional threads, just like different designs of threads. For example, threads used can be twisted, profiled, textured and / or braided. In preferred Configurations, the basic thread and / or the first thread and / or the second thread and / or optionally an additional thread can be a plastic material, in particular selected from the group comprising polyester (PES), polyamide (PA), polypropylene (PP), polyethylene (PE) and aramid, and / or cotton. In a preferred embodiment, the second thread can comprise stainless steel and / or copper and / or be a monofilament thread in order to obtain excellent abrasive effects. The threads and / or the knitted fabric per se can at least partially have a coating. For example, it makes sense for some applications to provide a hydrophobic coating on the inside of the hose-like cleaning element.

In a particularly advantageous embodiment, provision can also be made for a liquid active agent, in particular cleaning agent and / or polishing agent, to be introduced into at least some of the threads of the knitted fabric for release over time. This means that the cleaning element of the cleaning device can already be supplied with an active agent stored, so to speak, in the knitted fabric, which due to the special properties of the micro-threads or super-micro-threads is released over time and develops its corresponding effect. Of course, it is also conceivable the other way round that a knitting agent is also introduced into the knitted fabric at a later point in time in order to be released there over time. The active agent does not necessarily have to be a cleaning agent and / or a polish, but other active agents are also conceivable, for example a medically active agent in animal dental care using a cleaning device according to the invention. It should be pointed out at this point that if the second thread of the loops, which is preferably designed as a monofilament thread, is supplemented by a multifilament thread, in particular also a microfiber or super microfiber, the storing and releasing effect can also be at least partially realized within the second loops.

In a particularly advantageous, specific embodiment of the present invention it can be provided that the knitted fabric of the cleaning section has basic stitches containing the basic thread for each wale and the first thread and the second thread containing catch stitches for some of the wales in at least one row, with at least the first and second loops resulting from floats lie in part of the catch meshes. This means that in the knitted fabric there can preferably be basic stitches and additional tuck stitches within a row, with floats initially lying between the tuck stitches after knitting, which in a preferred further production step, the shrinking, arise due to the contracting effect of the shrinking and over the the basic mesh structure resulting from the basic mesh protrude. The decision as to where the catches and floats are, ultimately also determines the density and distribution of the loops in the finished product.

In the context of the present invention, it is therefore particularly preferred if the different size of the loops is produced by shrinking for at least a pair of first and second loops formed from the same float. Here, the different properties of the first and second thread are also used with regard to the shrinkage in order to make floats of the same length of the first and second thread, which may initially lie on top of one another, differently high by shortening the first and second thread within the scope of the shrinking process to get towering first and second loops. Such a configuration enables particularly simple production on a knitting machine, since the first and the second thread can be treated the same when knitting.

On the other hand, it is additionally or alternatively, however, also conceivable to at least partially generate the different sizes of the first and second loops by different float lengths. For example, it is therefore possible to use different threads for the first and second threads when knitting Provide float lengths, which can lead to different loop sizes.

In the context of the present invention, the shrinking can for example and preferably take place in that the cleaning device is treated with steam at a temperature of 3-5 seconds, in particular 6 seconds, contact time at 130-150 ° C., preferably 140 ° C. Other shrinking methods, for example ironing, washing at temperatures greater than 40 ° C., preferably greater than 60 ° C., and tumbling are also conceivable.

In general, the height of the loops can be adjusted, for example, via the distances between the catch meshes, that is to say the length of the float. The frequency of the loops can be adjusted via the number and / or spacing of the floats and / or rows of stitches with catch stitches. Staggered loops can also be provided in different rows of stitches by choosing an offset ("shifted") assignment of catch stitches and / or floats to wales. In this way, the product can also be adapted to the corresponding, desired application with regard to the size of the loops and / or the number / density distribution of the loops. In particular, it is also conceivable to use different float lengths for the respective thread for the first and / or the second thread in order to implement different sized loops, for example in different areas.

This again illustrates the particular advantages that the use of a knitted fabric and the corresponding production, in particular by means of a knitting device, bring with it. By fine adjustments to an associated knitting program and / or adjustments to the threads / materials used, cleaning devices for a wide variety of applications can be easily produced with the same knitting device, for example finger cots for cleaning animal teeth, tongue cleaners, rim and / or spoke cleaners, pipe cleaners and much more.

With particular advantage, at least one additional thread for producing at least one desired property can also be guided in parallel with the basic thread and / or the first thread and / or the second thread. This means that the basic stitches as well as the tuck stitches / floats can consist of several threads, guided in parallel, in particular by means of a knitting device. In a specific embodiment, it can be provided that the basic thread, in particular designed as a multifilament thread, has an additional thread that produces the elasticity of the basic mesh structure, in particular an elastane thread and / or a silicone thread, and / or the second thread, in particular designed as a monofilament thread and / or metal thread, an additional thread in particular for receiving multifilament thread serving for active agent and / or surface increase and / or the first and / or second thread are guided in parallel by an additional elastic thread contributing to the defined formation of the loops from the floats.

A specific, preferred embodiment of the present invention can provide that the basic meshes consist of two threads, namely the basic thread as a multifilament thread, the filaments of which, as is usual with micro-yarns or super-micro-yarns, can have a filament denier of less than 1 dtex, and one is elasticity producing additional thread, for example an elastomer thread / elastane thread, silicone thread and / or rubber thread. The catch stitches and floats / loops can consist of three or more parallel threads, namely in addition to the first thread, which is preferably designed as a multifilament thread, the second thread, which is preferably designed as a monofilament thread and / or metal thread, of a first elastic additional thread that contracts when it shrinks and thus acts as a loop former, and a second additional thread designed as a multifilament thread for the second thread, which provides an increase in the surface area of the second loops and also provides storage properties for abrasion and / or active agents.

Just as other properties of the knitted fabric can be selected differently depending on the application, this also applies to the usable density. For example, it can be provided that the knitted fabric has seven to twenty-two courses per centimeter, preferably eleven courses per centimeter, and / or four to twelve wales per centimeter, preferably eight wales per centimeter.

As already mentioned, the cleaning element can preferably be a finger cot to be turned out onto a finger as a carrier, the cleaning device then in particular consisting of the finger cot. A finger cot has a tube-like basic shape, in particular closed on one side. It preferably consists entirely of an elastic knitted fabric, so that it can be manufactured “in one piece”, so that no seams or the like are necessary.

Alternatively or additionally, it can be provided that the cleaning device also has the carrier for the cleaning element. The carrier can, for example, have a rod-like and / or spoon-like basic shape, a spoon-like basic shape being preferred as a cleaning device for a tongue cleaner.

It should be noted at this point that when it is designed as a finger cot, but also when the cleaning element is slipped onto a carrier, the cleaning element can preferably also have a locking means for reliably holding the cleaning element on the carrier, for example the finger, in particular if it is Elasticity is insufficient for support. For example, it is conceivable to work a rubber band into a lower hem of a finger cot as a locking means. If the cleaning device also has a carrier, its shape, given an elastic cleaning element, can likewise already contribute to locking the turned-on cleaning element.

In addition to the cleaning device, the present invention also relates to a method for producing a cleaning element of a cleaning device according to the invention, comprising the following steps:

• Knitting a knitted fabric for at least the cleaning section, in particular the entire cleaning element, which has tuck stitches containing the basic thread for each wale and the first thread and the second thread for a part of the wales in the cleaning section in at least one course, with at least one part between the fishing mesh floats, and
• Shrinking the knitted fabric to form the first and second loops from the floats.

All of the statements relating to production with regard to the cleaning device according to the invention can be applied analogously to the production method according to the invention, in particular with regard to the materials and / or threads to be used, the arrangement of the catch meshes / floats and the like. The production method according to the invention therefore provides a particularly simple and inexpensive way to produce cleaning elements for different applications, as has already been explained in relation to the cleaning device according to the invention.

a cleaning device according to the invention according to a further embodiment.

Fig. 1 shows a first embodiment of a cleaning device 1 according to the invention, which in the present case consists of a cleaning element 3 designed as a finger cot 2, which can be slipped onto a finger of a hand of a person, i.e. a user. For this purpose, the finger cot 2 consistently consists of a knitted fabric knitted in one knitting process, which has different properties in a shaft section 4 than in a cleaning section 5, which does not necessarily have to extend to the tip 6, as shown here, and also, for example, only the front of the Can cover fingerlings 2. The shaft section 4 is a simple, knitted knitted fabric of an elastic type, which only ensures a good fit on the finger as a support and protection of the finger.

In the cleaning section 5, the knitted fabric comprises, in addition to a basic thread that forms the basic mesh structure 7, at least two threads with different abrasive effects, in the present case a first thread designed as a multifilament thread with microfilaments or super microfilaments, i.e. a microfiber or super microfiber, the first in Fig. 1 For the sake of clarity, loops that protrude from the basic mesh structure 7, which protrude from the basic mesh structure 7, and a second thread, here designed as a monofilament thread, which protrudes as part of second loops 8 over the basic mesh structure 7 and the first loops, so that a total of one Loop knitted fabric results. The protruding second loops 8 have an abrasive effect that is at least 30%, preferably 100% higher than that of the first loops, which form a type of pile.

Fig. 2 explains the meshing in the first embodiment in more detail. As is known in principle, the stitch structure comprises several courses 9 and several wales 10, which in the present case are formed on a base thread 11 that corresponds to the first thread 18 Base mesh 12 refer. In each of the rows of stitches 9, however, in addition to the basic stitches 10, there are also tuck stitches 13 and floats 14 lying between tuck stitches 13, which are in particular also formed by the first thread 18 and the second thread 16.

In addition to the main thread 11, the first thread 18 and the second thread 16, the first thread 18, as described, was selected as a multifilament thread, for example made of PES, and the second thread 16 as a monofilament thread, for example made of polypropylene (PP), Additional threads are used to bring about certain properties of the cleaning device 1 and to promote the formation of the first loops and the second loops 8, which are intended to result from the floats 14 by shrinking.

As by splitting in the right part of the Fig. 2 shown in the drawing, the basic stitches 12 are formed from two parallel threads 11, 15, namely the basic thread 11 and the additional thread 15, which here is an elastic thread, for example an elastane thread or silicone thread, and which promote the elasticity of the knitted fabric and the contraction when it shrinks / should provide. The floats 14 and the tying stitches 13 are formed by three or more threads 16, 17 and 18 running in parallel. The second thread 16 and the first thread 18 have already been described. The at least one additional thread 17 can be a multifilament thread which, on the one hand, provides an enlarged surface area of the second loops 8, but on the other hand, due to the microfilaments or super microfilaments, provides a storage option for active agents, and / or a further elastic thread that contracts in the transverse direction when it is shrunk and thus ensures a defined formation of the loops 8. That is, by shrinking the in Fig. 2 The mesh structure shown in Fig. 1 The illustrated structure of the cleaning section 5 with the first loops and the second loops 8, whereby the different properties of the first thread 18 and the second thread 16 are specifically exploited during shrinking, so that the first loops and the second loops 8 are given different sizes despite the same float length .

The first thread 18 has a single filament denier of less than 2 dtex, the second thread 16 a single filament denier of greater than 20 dtex. The first thread 18, as a micro thread or super micro thread, therefore provides a polishing and cleaning effect and also allows active agents, for example cleaning agents and / or polish, to be buffered. In addition, abrasion is largely retained until the cleaning element 3 is cleaned. It is therefore also expedient to design the basic thread 11 in the same way as the first thread 18. The second thread 16 gives the second loops 8 an abrasive effect, that is to say, in particular, an abrasive or scouring effect. In this way, target surfaces, for example on the spokes of a bicycle, are cleaned and polished / cleaned in one operation. Due to the use of the knitted fabric, a robust material of the finger cot 2 with excellent elastic properties is available, which, in addition, due to the knitted production, does not have any seams that could have a disruptive effect.

It should be noted at this point that in the present exemplary embodiment an active agent can be introduced into the base bevels 11 and / or the first thread 18 and / or the additional thread 17, which is released over time and, for example, the cleaning and / or the polishing effect of the cleaning device 1 is supported.

The size and positioning / density of the first loops and the second loops 8 can be based on the illustration in FIG Fig. 2 easily modified. For example, a float 14 can span a plurality of basic meshes 12 in the row direction in order to obtain larger first loops and second loops 8. Less common first loops and second loops 8 can be achieved by using successive tuck stitches 13 in a course 9 and / or by omitting tuck stitches 13 / floats 14 for some of the courses 9. As in Fig. 2 As shown, an even distribution of the first loops and the second loops 8 can also be achieved by providing the floats 14 offset.

Fig. 3 shows the resulting structure according to Fig. 2 after shrinkage more precisely. The first loops 22 formed from the first thread 18 protrude above the basic mesh structure 7 and achieve the polishing effect as a kind of pile. The second loops 8 protrude higher than the first loops 22 over the basic mesh structure 7 and exhibit an abrasive effect. Fig. 4 shows the finger cot 2 as it is attracted to the finger of a hand 20. As can be clearly seen, the cleaning section 5 extends over the fingertip 21 to the fingernail, which can be achieved due to the design in knitted knitwear.

Fig. 5 shows a second embodiment of a cleaning device 1 'according to the invention, which can be used, for example, as a tongue cleaner. In the present case, the cleaning device 1 ′ comprises a spoon-like carrier 19 onto which the correspondingly shaped cleaning element 3, again made of elastic knitted fabric, can be slipped. The cleaning element 3 again has a shaft section 4 and a cleaning section 5, the knitted fabric of which is designed like the finger cot 2.
