Description

TECHNICAL FIELDThe present invention relates to a cleaning attachment for a container. The present invention further relates to a cleaning kit comprising the cleaning attachment and a container.BACKGROUND OF THE INVENTIONCarpet brushes are special cleaning tools developed for the thorough care and cleaning of carpets. Their construction varies depending on the model and intended use, but typically consists of a handle or housing, a brush roller or fixed bristles and a mechanism for moving the bristles. Manual carpet brushes usually have a simple construction with a stable handle and fixed or movable bristles made of plastic or natural fibres. Electric models have a rotating brush roller that is driven to loosen deep seated dirt.The use of carpet brushes ranges from simple brushing of dust and hair to intensive cleaning with special cleaning agents or steam function. Manual brushes are well suited for smaller surfaces or the removal of animal hair, while electrical variants, often available as carpet separators or as attachments for vacuum cleaners, allow a deeper cleaning. Special carpet shampoo brushes also aid in wet cleaning by incorporating cleaning agents and simultaneously loosening the carpet. The choice of the proper carpet brush will depend on the type of carpet and the desired cleaning effect.Carpet brushes with an integrated detergent bottle are known from the prior art. Its structure combines a brush unit with a container for cleaning agent, so that the cleaning agent can be applied in a targeted manner to the surface to be cleaned. Carpet brushes with an integrated cleaning agent bottle are known from the prior art, wherein both the carpet brush is manufactured from different plastics and the cleaning agent bottle is manufactured from at least one further plastics material.Recycling products made of several different plastics entails several disadvantages. Different plastics must be sorted before recycling, since they are often incompatible. This is time consuming and requires specialized procedures. If different plastics are recycled mixed, they cannot bond completely, which deteriorates the mechanical properties of the new material. Sorting, cleaning and reprocessing require additional resources, which makes recycling expensive. Since the separation is complicated and often uneconomical, many such products land in refuse incineration or on landfills despite theoretical recycleability.DESCRIPTION OF THE INVENTIONObject of the InventionIt is therefore the object of the present invention to provide a cleaning attachment for a container as well as a cleaning kit comprising the cleaning attachment and a container, starting from the prior art, which overcome the disadvantages of the prior art.In particular, the object of the present invention is to provide a cleaning attachment for a container and a cleaning kit comprising the cleaning attachment and a container, which have increased recycling ability. Moreover, it is the object of the present invention to provide a cleaning attachment for a container and a cleaning kit comprising the cleaning attachment and a container, which enable the container to be easily refilled. Finally, it is an object of the present invention to provide a cleaning attachment for a container and a cleaning kit comprising the cleaning attachment and a container that enables uniform distribution of a cleaning agent onto carpet fibers.Technical SolutionThis object is achieved according to the subject matter of the independent claims. Further embodiments are evident from the subject matter of the dependent claims and the following description of the invention.The object is achieved in particular by a cleaning attachment for a container, whereinthe cleaning attachment comprises a cleaning part and a connecting part;the cleaning portion comprises a plurality of bristles and a sponge;the connecting part is designed to form a firm connection between the cleaning attachment and the container with a complementarily designed connecting part of the container; andthe cleaning attachment has a cavity configured to allow a transfer of a liquid from the container to the cleaning part;- characterized in that all the components of the cleaning attachment are made of the same material.This object is furthermore achieved in particular by a cleaning kit comprising a cleaning attachment according to one of the preceding claims and a container, whereinthe container has a complementary connecting portion configured to form a tight connection with the connecting portion of the cleaning attachment;a complementarily shaped connecting part comprising an opening configured to allow a transfer of a liquid from the container to the cleaning attachment; andcleaning attachment and the container are made of the same material.Technical EffectsThe cleaning attachment according to the invention and the cleaning kit according to the invention are distinguished by an increased recycling capacity.

Rather, the terms and words used should be construed in a sense and concept consistent with the technical idea of the present disclosure based on the principle that the inventor can properly define the concept of a term to describe this invention in the best possible manner.Unless otherwise limited, a detailed description defining or specifying the elements may be applied to all of the inventions and is not limited to descriptions of particular inventions. That is, the present disclosure also relates to combinations of the embodiments, although not separately disclosed.The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The singular forms "a", "an" and "the / s" include plural referents unless the context clearly dictates otherwise. It should be understood that the terms such as "comprise" or "have" as used in the present specification are intended to refer to the presence of stated features, numbers, steps, operations, components, parts, or combinations thereof, but are not intended to exclude the possibility of the presence or addition of one or more other features, numbers, steps, operations, components, parts, or combinations thereof. The term "comprising" expressly includes the meaning "substantially comprising" and "consisting of", although not necessarily limited accordingly.The term "substantially comprising" as used herein has the meaning of "at least 70% comprising", preferably "at least 80% comprising", most preferably "at least 90% comprising". When referring to the amount of a component in a material mixture, % is % by weight based on the total weight of the respective mixture. For example, a material substantially comprising a polymer comprises the polymer in an amount of at least 70% by weight based on the total weight of the corresponding material.As used herein, "A and / or B" means "A and B or A or B.".Cleaning attachmentAccording to a first aspect, the present invention relates to a cleaning attachment for a container. The cleaning attachment includes a cleaning part and a connecting part.The cleaning part includes a plurality of bristles and a sponge. The plurality of bristles and the sponge are disposed on a part of the surface of the cleaning part.The term "sponge" in the sense of the present invention denotes a porous material with an open-cell or closed-cell structure, which is suitable for absorbing and / or releasing liquids and can also be understood from a technical point of view as foam (foam-like structure).In particular, it can be provided that the cleaning part comprises a body of planar configuration and the plurality of bristles and the sponge are arranged on a surface of the body of planar configuration. It is preferably provided that the plurality of bristles and the sponge are arranged on a surface of the body of planar configuration which is remote from the connecting part. The term "facing away" here does not merely denote an arrangement in which the surface of the body of planar configuration, which is facing away from the connecting part, is arranged at an angle of 90° with respect to a connecting axis which extends from the connecting part to the surface. Instead, it can be provided that the said angle is less than 90°, i.e. the surface of the connecting part on which the plurality of bristles and the sponge are arranged, has an inclination. This makes it possible to achieve easier handling of the cleaning attachment. The term "planar" can refer to a planar configuration of the surface. A concave, convex, wave-shaped, etc. configuration of the surface can likewise be provided.The body of planar configuration has at least one opening which enables a transfer of a liquid from the connecting part to the cleaning part, in particular enables the liquid to be transported to the sponge. It can be provided that the body of planar configuration has a multiplicity of openings (holes). A liquid, for example a cleaning liquid, which can pass through the connecting part to the cleaning attachment, for example after connecting the cleaning attachment to a container which contains the liquid, can reach the sponge and / or the plurality of bristles, in particular the sponge, in order in particular to wet (wet) the sponge, thus preferably to generate a foam in and on the sponge and thus to enable the cleaning attachment to be used for cleaning a surface, in particular a surface which has a plurality of fibers, for example a carpet. It can therefore be provided that the sponge is arranged over at least one opening of the body of planar configuration. An optimum cleaning effect can thereby be achieved.It can be provided that the plurality of bristles is formed in a plurality of separate bristle bundles. This can increase the stability of the brush part formed by the plurality of bristles and improve the cleaning effect.In addition, it can be provided that the plurality of bristles delimit the sponge, i.e. are arranged around the sponge. In other words, it can be provided that the sponge is arranged centrally on the body of the cleaning part which is configured in a planar manner and the plurality of bristles, preferably in the form of bristle bundles, is arranged around the sponge. In particular in this arrangement, it is preferred that the sponge is arranged over at least one opening of the body of planar configuration, as a result of which a liquid, for example a cleaning liquid, which reaches the sponge through the connecting part, for example after connecting the cleaning attachment to a container which contains the liquid. By means of the moistened or wet sponge, the liquid (cleaning liquid) can thus be applied, with optional foaming, to a surface to be cleaned, in particular a surface which has a multiplicity of fibers, for example a carpet. Subsequently and / or simultaneously, a mechanical cleaning of the surface to be cleaned can then take place, in particular by the plurality of bristles surrounding the sponge. This allows particularly thorough cleaning of the surface to be achieved. In addition, a particularly uniform distribution of the cleaning agent on the surface can be achieved.It can furthermore be provided that the plurality of bristles comprises a first type of bristles and a second type of bristles, wherein the first type of bristles and the second type of bristles differ from one another in at least one property, preferably in length and / or elasticity. Due to the different properties of the first type of bristles on the one hand and the second type of bristles on the other hand, an improved cleaning effect can be achieved. For example, longer and / or harder (less resilient) bristles may provide for improved removal of coarse contaminants from a surface to be cleaned, while shorter and / or softer (more resilient) bristles may simultaneously serve for the removal of finer and deep seated contaminants. For example, it can be provided that the first type of bristles is longer and / or harder than the second type of bristles and the first type of bristles delimits the second type of bristles, i.e. for example the second type of bristles forms an inner ring around the sponge and the first type of bristles forms an outer ring surrounding the inner ring. In particular, in such an arrangement, an optimum cleaning effect can be achieved.The cleaning attachment includes a connecting part in addition to the cleaning part. The connecting part is designed to ensure a firm connection between the cleaning attachment and the container with a complementarily designed connecting part of a container to which the cleaning attachment is to be connected. For example, the connecting part can have an internal thread and the connecting part of the container an external thread, wherein the internal thread and the external thread are formed complementary to one another. Alternatively, the complementary connecting parts can be configured to produce a click connection. Alternative connection forms known from the prior art can likewise be provided.The cleaning attachment has a cavity which is designed to allow a transfer of a liquid from the container to the cleaning part. It can be provided that the cleaning attachment is hollow and comprises at least two openings, in particular a first opening which is part of the connecting part and a second opening which is part of the cleaning part, can be in direct contact with the sponge. In this arrangement, a liquid, for example a cleaning liquid, can pass through the first opening into the cavity of the cleaning attachment and from there to the second opening. The liquid emerging through the second opening can preferably wet, wet, etc. the sponge arranged there and preferably form a foam.All the components of the cleaning attachment, i.e. the entire body of the cleaning attachment as well as the bristles and the sponge applied to this body, are made of the same material. In this case, it can be provided that the material, i.e. the "same material", from which all the constituents of the cleaning attachment are produced, is a recyclable polymer. The term "identical material" in the sense of the present disclosure can be aimed at a polymer, in particular a recyclable polymer, which is produced from the same monomer units but differs in other properties, in particular in molecular weight. In other words, for example, a polyethylene having a weight average molecular weight M w100.000 is "the same material" as a polyethylene having a weight average molecular weight M w of 1,000,000. The use of the same material for all constituents of the cleaning attachment achieves increased recycling capacity. In particular, more than 99% of the material used can be recycled.The recyclable polymer may be selected from the group consisting of polyolefin, preferably polyethylene, in particular HDPE and LDPE, or polypropylene; polyamide, in particular polyamide-6; polyurethane; and polyethylene terephthalate.It may be provided that the recyclable polymer has a density of less than 1 g / cm 3.It can be provided that the recyclable polymer is a polyolefin. It can be provided that the recyclable polymer is polyethylene or polypropylene. It can be provided that the recyclable polymer is polypropylene. It may be provided that the recyclable polymer is polyethylene. In this case in particular, significantly more than 99% of the material used can be recycled.It may be provided that the recyclable polymer is polyethylene with a density of less than 1 g / cm 3 and may in particular be selected from the group consisting of low density polyethylene (LDPE): density about 0.91-0.94 g / cm 3 linear low density polyethylene (LLDPE): density about 0.91-0.94 g / cm 3 high density polyethylene (HDPE): density about 0.94-0.97 g / cm 3 ultra high molecular weight polyethylene (UHMWPE): density about 0.93-0.98 g / cm 3.Cleaning kitAccording to a second aspect, the invention relates to a cleaning kit, i.e. a set of different cleaning tools and, preferably, cleaning agents. The cleaning kit comprises at least the cleaning attachment described in detail above and a container. The cleaning attachment and the container as well as all further components of the cleaning kit which are not consumed during use thereof, i.e. in particular a cleaning liquid optionally contained in the container, are made of the same material. The use of the same material for all constituents of the cleaning kit achieves increased recycleability. In particular, over 99% of the material used can be recycled, especially if the material is polyethylene.The container has a complementarily shaped connecting part which is configured to form a fixed connection with the connecting part of the cleaning attachment. For example, the connecting part of the cleaning attachment can have an internal thread and the connecting part of the container can have an external thread, wherein the internal thread and the external thread are formed complementary to one another. Alternatively, the complementary connecting parts can be configured to produce a click connection. Alternative connection forms known from the prior art can likewise be provided.The complementarily shaped connecting part of the container comprises an opening configured to allow a transfer of a liquid from the container to the cleaning attachment. For example, the complementarily shaped connecting part of the container comprising an opening can be a screw closure opening.The container may be a bottle, canister, can, flat container, bag, tube, etc. The container is preferably a bottle. Preferably, the container has an internal volume selected from the group consisting of from 50 ml to 2 L, from 100 ml to 1.5 L, from 250 ml to 1 L, and from 500 ml to 750 ml.In one embodiment, the cleaning kit further comprises a seal.The seal is arranged in the opening of the complementarily configured connecting part of the container and completely closes this opening. The seal can be arranged in the opening in a fixed but removable manner. When the seal is removably disposed in the opening, the seal may be considered a stopper. For example, the seal can have a sealing bead which can form a click connection with a complementary bulge in the complementarily formed connecting part of the container. This ensures that the seal closes the opening of the container sufficiently tightly to prevent a liquid contained in the container from leaking out, for example during transport, but at the same time the seal can be removed without disproportionate effort and without damage to the container in order to refill the container after a liquid contained in the container has been used up. This achieves an environmentally harmless re-use of the container as a component of the cleaning kit.The seal is preferably made of the same material as the cleaning attachment and the container.The seal has a tapered location configured such that mechanical piercing of the tapered location allows transfer of a liquid from the container through the mechanically pierced tapered location. The tapered point is made of the same material as the remaining seal, but has a reduced wall thickness. The wall thickness (taper) is adjusted during the production of the seal in such a way that the tapered point can be penetrated simply by the end user without special tools, but merely with the aid of easily available means, such as a needle, a pin, etc., in order to create an opening through which a liquid contained in the container can leave the container. In this way, it is ensured that the liquid contained in the container remains securely enclosed in the container during the transport of the cleaning kit to the end user and only immediately before use is contact of the liquid allowed with the environment allowed. This also makes it possible to avoid contamination of the liquid.It may further be provided that the cleaning kit comprises a liquid contained in the container. The liquid can be in particular a cleaning liquid, for example a liquid carpet cleaner. Corresponding cleaning fluids, in particular liquid carpet cleaners, are known to the person skilled in the art from the prior art.DETAILED DESCRIPTION OF THE INVENTIONThe invention will be described in detail below with reference to the figures.
