Description

[0001] The invention relates to a urinal insert element for a urinal device.

[0002] Sanitary liners for the purpose of urination or, more broadly, the treatment of urine are already widespread. Most primarily serve to reduce, if not completely prevent, excessive splashing of urine within the sanitary fixture. This is often achieved by dispersing, distributing, or breaking the incoming stream. Most solutions involve manufacturing the majority or even the entire liner from plastic. Besides offering a certain degree of stability and considerable design freedom, the advantages lie particularly in cost-effective production. This design freedom is especially beneficial because it allows for a variety of ways to achieve the technical effect of treating the incoming stream.For example, sieve structures or studded structures are known to exert this technical effect on the beam. However, in times when it is increasingly important to avoid plastic waste, plastic inserts are not sustainable and therefore not advantageous for the sustainable design of corresponding products. So far, no solutions are known that rely predominantly on natural substitutes while simultaneously retaining the existing advantages, especially the technical ones.

[0003] Solutions already exist in the prior art that address this sustainability issue in the broadest sense. Two prior art documents are presented below as examples.

[0004] A sanitary liner is known from German patent application DE 10 2022 111 388 A1. This patent describes a sanitary liner, in particular a urinal liner, comprising a mat-shaped base body with a first flat side and a second flat side opposite the first, which allows the liner to be placed on the sanitary fixture. The liner also includes at least one or more openings extending from the first flat side to the second flat side through the mat-shaped base body, or it includes a plurality of studs extending from the first and / or second flat side of the mat-shaped base body. The liner is made of a water-soluble material or comprises a water-soluble material that gradually dissolves over time.

[0005] A splash guard urinal strainer is also known from US patent 20150284940A1. This splash guard urinal strainer consists of a flat base, an outer and an inner cup, and a mesh screen. The flat base has a grid that allows liquid flow and provides mounting slots for connecting the components. The outer cup yields when compressed, causing tabs to engage in the mounting slots and secure the components. The outer cup has a first opening in a curved area. The inner cup has a second opening of approximately the same size. Its shape is adapted to the outer cup so that they fit together precisely, with the openings aligning. The mesh screen fills the space between the outer and inner cups, allowing liquid to flow through the openings and the mesh.

[0006] The solutions presented in the state of the art already offer initial approaches to making the associated objects more sustainable. This is achieved, for example, by reducing the amount of material used through the use of interlocking constructions. This already demonstrates a promising approach to reducing plastic waste in the future. However, waste still remains after use that must be disposed of, and for hygienic reasons, this waste can only be partially integrated into a circular economy. Water-soluble materials are advantageous for the user, as they eliminate the need for disposal. However, some experts are already voicing their concerns, viewing the introduction of self-dissolving films or similar materials as only partially beneficial or even as a new environmental problem.

[0007] The invention is based on the objective of providing an alternative urinal insert element for a urinal device that, on the one hand, provides a sustainable solution without being detrimental with regard to the technical effect.

[0008] This problem is solved using the features of claim 1.

[0009] In a preferred embodiment of the invention, a urinal insert element for a urinal device is provided, comprising a mat-shaped base body with a first surface side and a second surface side opposite the first surface side, with which the urinal insert element can be placed on a urinal device. The base body further has at least one or more openings extending from the first surface side to the second surface side through the base body. In addition, the base body comprises at least partially plant-based cellulose sponge material.

[0010] Plant-based cellulose sponge material is compostable after use and is also a renewable resource that can be cultivated organically and sustainably without artificial additives, so the urinal insert element according to the invention can be considered a sustainable solution for a urinal device. Plant-based cellulose sponge material also offers the advantage that its structure is naturally designed to disperse, spread, or break up an impacting stream of urine. In this respect, the present technical solution naturally possesses a structure that is not only at least partially permeable to fluids, such as water, urine, or a water-urine mixture, but also simultaneously has the technical feature of a splash guard.The texture or structure of plant-based cellulose sponge material is naturally so diverse that even at varying angles of incidence, a stream striking the urinal insert can be reliably and safely dispersed, distributed, or broken. In contrast to previous solutions, which have a fixed, predetermined structure, the urinal insert according to the invention offers the advantage of a particularly diverse structure without requiring any particularly costly effort. Therefore, the presented solution is not only sustainable and offers a special technical benefit, but also presents itself as a cost-effective alternative to existing solutions. In the context of these technical instructions, the term "surface side" can, for a person skilled in the art, refer not only to the actual, outward-facing side, but also to an outer area of ​​the element as a whole.In extreme cases, this area can extend to a second object, which also has a surface and which can also encompass an area, so that both surface surfaces of the two objects can be connected without the actual, outward-facing sides necessarily having to touch.

[0011] Further preferred embodiments of the invention result from the other features mentioned in the dependent claims.

[0012] In a further preferred embodiment of the invention, the plant-based cellulose sponge material comprises at least partially loofah sponge material. Loofah sponge material offers the advantage of naturally possessing a particularly pronounced structure due to its numerous fibers. The skeletal structure of the dried interior of the loofah fruit can be considered such a loofah sponge material. The diversity of interconnected fibers in this loofah sponge material is particularly evident in the fact that each loofah fruit is unique, and there is a virtually unlimited number of variations of this internal structure, or rather, this sponge-like structure.An incident jet is thus dispersed, distributed, or refracted in a variety of ways, with even the initial dispersed, distributed, or refracted components of a jet striking the urinal insert being further dispersed, distributed, or refracted. The deeper the jet penetrates into the internal structure of the loofah sponge material, the greater the probability that it will be completely dispersed, distributed, or refracted. This offers the advantage that the urinal insert according to the invention exhibits this technical effect particularly reliably, so that it can be considered not only a particularly sustainable but also a particularly reliable alternative to existing solutions.

[0013] In a further preferred embodiment of the invention, the plant-based cellulose sponge material consists of at least partially compressed loofah sponge material. Without unduly diminishing the aforementioned advantages, this embodiment offers the additional benefit of being particularly space-saving when inserted into a urinal device. Even in its partially compressed state, loofah sponge material still exhibits a sufficiently complex structure, allowing an incident stream to be dispersed, distributed, or broken in a variety of ways. Furthermore, this reduces the packed size of the urinal insert element according to the invention, thus enabling cost-effective transport.

[0014] In a further embodiment of the invention, the plant-based cellulose sponge material consists of at least partially compressed loofah sponge material, wherein the at least partially compressed loofah sponge material comprises a portion of the inner fibrous network of a loofah fruit. The inner fibrous network of a loofah fruit can be understood, in particular, as the skeletal structure of the loofah fruit that remains after the outer shells and other components, such as seeds, are removed from the fruit, leaving only the interconnected fibrous structure after drying. In other words, the inner fibrous network of a loofah fruit can be considered the cellulose-rich fibrous framework that remains after drying. This cellulose-rich fibrous framework can be elastic, coarse-pored, highly absorbent, and also biodegradable.With sufficient rinsing with water, as is the case with conventional urinal devices, any remaining urine is reliably flushed away, so that the urinal insert element according to the invention can also be considered suitable for longer periods of use.

[0015] Furthermore, in a further embodiment of the invention, the portion of the inner fibrous network of the loofah fruit with its original structure is at least partially compressed in a skeletal form, so that the original structure, due to its lignified and spongy cellulose structure, serves as a splash guard. The aforementioned advantages also apply, insofar as they are transferable, to this embodiment of the invention.

[0016] In a further preferred embodiment of the invention, the base body comprises at least partially plant-based cellulose sponge material, in particular at least partially compressed loofah sponge material, and at least one other material. An additional material can be advantageous, for example, if a particular geometry, especially a particular three-dimensional geometry, is desired which is intended to extend beyond and further complement the natural structure of the plant-based cellulose sponge material.

[0017] Furthermore, in a further embodiment of the invention, at least one additional material is selected from: compostable bioplastic; wood; water-soluble material; organic plastic; inorganic plastic; beeswax; carnauba wax; soy wax; linseed oil; tung oil; wood oil mixture; biopolymers; chitosan; silane; siloxane; epoxy; acrylic. Depending on the intended use and service life of the urinal insert according to the invention, a specifically designed configuration can thus be provided. For example, additional reinforcement can be provided to advantageously support a structure of the wet plant-based cellulose sponge material of the urinal insert according to the invention that may become too flexible. Natural substances can thereby reinforce the sustainable nature of the plant-based cellulose sponge material.The use of artificial materials can be reduced to a minimum, so that a comparatively sustainable solution can still be provided.

[0018] Furthermore, in a further embodiment of the invention, the urinal insert element comprises at least one insert element, and the base body has at least one chamber between the first and second surface sides designed for inserting the at least one insert element. Additional functions can thus be integrated into the urinal insert element according to the invention. Such an insert element can also advantageously support a structure of the wet plant-based cellulose sponge material of the urinal insert element according to the invention that might become too flexible. In this respect, the plant-based cellulose sponge material can fully develop its technical effect, even when wet, and at the same time, the insert element can provide additional reinforcement to the overall structure, thus advantageously enabling additional functions.In an extreme case, the insert element can, for example, be a solid element whose consistency is comparable to that of a stone or the like, and in which the element is then wrapped with, for example, loofah fiber mesh or the like, so that a splash guard can be provided while maintaining sufficient stability in all conditions.

[0019] In a further embodiment of the invention, the insert element is also selected from: a fragrance element; a cleaning element; or a fragrance and cleaning element. Fragrance elements, cleaning elements, and fragrance and cleaning elements can thus be considered additional functions of the urinal insert element according to the invention and can, for example, advantageously extend its service life without resulting in undesirable soiling or unpleasant odors.

[0020] Furthermore, in a further embodiment of the invention, the plant-based cellulose sponge material is impregnated with one or more active ingredients suitable for cleaning, disinfecting, and / or scenting, and / or which increase the stability of the urinal insert element. The active ingredient is, in particular, a biological cleaning agent or comprises a biological cleaning agent, and / or the active ingredient is selected from: compostable bioplastic; water-soluble material; organic plastic; inorganic plastic; beeswax; carnauba wax; soy wax; linseed oil; tung oil; wood oil mixture; biopolymers; chitosan; silane; siloxane; epoxy; acrylic. In this way, even in its comparatively simple embodiments, the urinal insert element can have additional functions.Fragrance effects, cleaning effects, and the like can thus be provided as additional functions of the urinal insert element according to the invention and can, for example, advantageously extend its service life without leading to undesirable soiling or unpleasant odors. These active ingredients can also advantageously increase the stability of the urinal insert element, particularly if the structure of the wet plant-based cellulose sponge material of the urinal insert element according to the invention becomes too flexible.Active ingredients, particularly those with an impregnating effect, can also make the plant-based cellulose sponge material of the urinal insert according to the invention less susceptible to the absorption of fluids such as water, urine, or a mixture of water and urine. This allows the natural structure to remain advantageously stable for a longer period and prevents the absorption of potentially odorous substances, thus extending the service life of the urinal insert according to the invention. For example, a wax impregnation can be applied. The plant-based cellulose sponge material, such as loofah material, can be dipped in molten beeswax, carnauba wax, and / or soy wax. It can then be held in such a way that excess active ingredient can drip off, and the treated urinal insert can subsequently be cooled.The effect can be described as follows: Wax or another active ingredient fills the pores of the cellulose and forms a hydrophobic (water-repellent) layer. An advantage of natural substances, such as beeswax or soy wax, is their biodegradability. Furthermore, these substances are considered non-toxic and have a pleasant feel. An oil or resin treatment can also be used. Examples of natural oils include linseed oil (raw or boiled), tung oil, or wood oil mixtures. The corresponding method might be as follows: The oils are applied in several coats, then allowed to penetrate thoroughly before curing during a settling period. The effect can be: esterification of the cellulose surface can occur, resulting in reduced water absorption and simultaneously increased strength. A chitosan or starch coating can also be applied. Biopolymers, such as chitosan (from crab shells) or modified starch, can be used as a thin coating. The effect can be: protection against microbes, slightly water-repellent, and biodegradable. Application might involve applying the solution and allowing it to dry. A silane or siloxane coating can also be applied. The underlying principle is as follows: organosilanes react with the OH groups of the cellulose to form a hydrophobic silicone layer.This offers the advantage that the urinal insert can be virtually permanently water-repellent without any significant increase in weight. A polymer coating (e.g., PU, ​​epoxy, acrylic) can also be applied. If, for example, plant-based cellulose sponge material, such as loofah, is used as a composite material (e.g., in biocomposites), it can be impregnated with resins. Examples include polyurethane, epoxy resin, and polylactic acid (PLA). This can result in very high strength.

[0021] In a further embodiment of the invention, the base body is also constructed from at least two at least partially compressed loofah sponge cores. The aforementioned advantages can thus be easily reinforced and, insofar as applicable, also apply to this embodiment of the urinal insert element according to the invention. During compression, the at least two loofah sponge cores, i.e., the dried skeletal structure of the loofah fruit, can interlock in such a way that a durable and sufficiently stable connection for the intended purposes can be formed between them.

[0022] In a further embodiment of the invention, the base body is constructed from at least two at least partially compressed loofah sponge fiber networks, wherein the at least partially compressed loofah sponge fiber networks are at least partially stacked on top of one another. The aforementioned advantages can thus be easily reinforced and, insofar as applicable, also apply to this embodiment of the urinal insert element according to the invention. During compression, the at least two loofah sponge fiber networks, i.e., the dried skeletal structure of the loofah fruit, can interlock in such a way that a durable and sufficiently stable connection for the intended purposes can be achieved between them.

[0023] Furthermore, in a further embodiment of the invention, the base body is constructed from at least two at least partially compressed loofah sponge fiber braids, wherein the loofah sponge fiber braids are provided to be at least partially stacked on top of each other, wherein a respective fiber longitudinal direction of the respective loofah sponge fiber braids is twisted relative to each other in an interval between 5° and 90°, preferably in an interval between 10° and 90°, preferably in an interval between 25° and 90°, preferably in an interval between 35° and 90°, preferably in an interval between 45° and 90°, preferably in an interval between 65° and 90°, preferably in an interval between 75° and 90°, so that the splash protection effect of the urinal insert element is increased overall.A 90° twist thus means that the two loofah sponge fiber networks lie on top of each other like a cross, and then an outer geometry can be created by means of cutting processes or the like. The aforementioned advantages can therefore be easily reinforced and, insofar as applicable, also apply to this embodiment of the urinal insert element according to the invention. When compressed, the at least two loofah sponge fiber networks, i.e., the dried skeletal structure of the loofah fruit, can interlock in such a way that a permanent and sufficiently stable connection for the intended purposes can be created between them. The respective twist can result in a particularly diverse structure, so that an impacting stream can be dispersed, distributed, or broken in a variety of ways.

[0024] In a further embodiment of the invention, the base body has at least one chamber between the first and second surface surfaces designed for inserting at least one insert element, wherein the at least one chamber is formed by means of at least one spacer element provided between the first and second surface surfaces. An incident beam can thus be further dispersed, distributed, or refracted in a variety of ways, since additional beam paths can be provided due to the spacer element. The resulting chamber can also be used for other purposes, requiring only at least one spacer element, which can be made, for example, of wood or another solid organic material.

[0025] In a further embodiment of the invention, the base body is provided to have a substantially round surface, the diameter of which can be adapted to the respective support surface in a urinal device into which the urinal insert element is placed. For example, it is conceivable that a basic shape in the form of a substantially round surface can be provided, which can then be adapted to the required fit for the urinal device, for example, by means of a tool (scissors or the like).

[0026] Furthermore, in a further embodiment of the invention, the base body has an edge region that is thinner than a central region of the base body and at which the first and second surface sides are at least partially reinforced. For a person skilled in the art, the term "surface side" in the context of this technical description can include not only the actual, outward-facing side but also an outer region of the element as a whole. In extreme cases, this region can extend to a second object, which also has a surface side and which can likewise encompass a region such that both surface sides of the two objects can be connected without the actual, outward-facing sides necessarily having to touch.In this way, premature fraying or similar issues at the edges can be easily prevented or even completely eliminated. An existing bond (or bonds) between these two sides, such as those created by the natural structure of the plant-based cellulose sponge material, can thus be reliably reinforced.

[0027] In a further embodiment of the invention, the first and second surface surfaces are connected to each other, at least partially, by means of a seam formed by another material. A seam provides particularly reliable reinforcement. Furthermore, premature fraying or similar issues at the edges can be prevented or even completely eliminated in a simple manner. An existing connection (or connections) between these two surfaces, such as those formed by the natural structure of the plant-based cellulose sponge material, can thus be reliably reinforced.

[0028] In a further embodiment of the invention, the additional material for forming the seam is selected from: cotton; compostable bioplastic; wood fibers; water-soluble material; metal; metal alloy; loofah fibers. The aforementioned advantages also apply to this embodiment, insofar as they are transferable. Furthermore, natural or easily handled materials can underscore the sustainable nature of the urinal insert element according to the invention.

[0029] Furthermore, in a further embodiment of the invention, the base body is provided with at least one handle element, in particular a tab-shaped handle element. Such a handle element can be advantageous for removing the urinal insert element according to the invention from the urinal device after use. It can, for example, be provided at an edge so that it is not directly exposed to a stream of urine during use.

[0030] In a further embodiment of the invention, it is also provided that the at least one or the plurality of passages are formed by the plant cellulose sponge material and are predetermined according to their natural structure. The aforementioned advantages also apply to this embodiment, insofar as they are transferable.

[0031] Unless otherwise stated in individual cases, the various embodiments of the invention mentioned in this application can be advantageously combined with one another.

[0032] The invention is explained below using exemplary embodiments with reference to the accompanying drawings. These show: Fig. 1 a schematic top view of a surface side of a urinal insert element 1 for a urinal device according to an embodiment of the present invention; Fig. 2 a schematic representation of a urinal insert element for a urinal device according to an embodiment of the present invention; Fig. 3 a schematic cross-sectional representation of a urinal insert element for a urinal device according to an embodiment of the present invention; Fig. 4 a further schematic cross-sectional representation of a urinal insert element for a urinal device according to an embodiment of the present invention; Fig. 5 a further schematic cross-sectional representation of a urinal insert element for a urinal device according to an embodiment of the present invention.

[0033] Fig. Figure 1 shows a schematic top view of a surface side of a urinal insert element 1 for a urinal device according to an embodiment of the present invention. An exemplary and purely schematic representation of a surface side of the urinal insert element 1 is shown. This can be a first or a second surface side of the urinal insert element 1. In particular, individual fibers 2 of a plant-based cellulose sponge material 3 of the urinal insert element 1 are shown in a highly simplified schematic representation. The plant-based cellulose sponge material 3 can, for example, comprise at least partially loofah sponge material. Likewise, the plant-based cellulose sponge material 3 can, for example, be made entirely of loofah sponge material. The fibers 2 of the plant-based cellulose sponge material 3 form a three-dimensional structure.In other words, the fibers 2 are not only present on the surface, but also extend into the urinal insert element 1 according to their natural position as determined by the growth of the plant cellulose sponge material 3. Likewise, several layers of these fibers 2 are present, which are at least partially interconnected, as illustrated by an example of a possible natural growth pattern of the plant cellulose sponge material 3. It is conceivable that a denser structure with more fibers 2 is provided in further embodiments. A sponge-like structure, such as that typically occurs naturally in loofah fiber networks, could also result in further embodiments of the presented urinal insert element 1.

[0034] Fig. Figure 2 shows a schematic representation of a urinal insert element 1 for a urinal device according to an embodiment of the present invention. The urinal insert element 1 is shown with a mat-shaped base body 4. The base body 4 is depicted as circular. However, in other embodiments not shown in detail, it is conceivable that other geometries are provided, for example, square, rectangular, or trapezoidal shapes. It is also conceivable that geometries are provided which are based on the shape of an insert area of ​​a urinal device. The base body 4 is also shown with a structure of fibers 2. This highly simplified form is shown with a symmetrical texture.This is merely an example, and natural textures or structures are conceivable in this basic body 4, such as those commonly found in nature in plant cellulose sponge material 3 or in loofah fiber networks or the like. In this sense, the following is an example: Fig. 1. The base body 4 has a plurality of openings 5 ​​due to the plant cellulose sponge material 3, which is present, for example, in the form of a planned loofah fiber network, extending through the base body 4 into the plane of the image. These openings 5 ​​of the base body 4 result from the fact that the base body 4 is made of plant cellulose sponge material 3, for example, loofah material.

[0035] Fig. Figure 3 shows a schematic cross-sectional view of a urinal insert element 1 for a urinal device according to an embodiment of the present invention. The urinal insert element 1 for a urinal device is shown with a mat-shaped base body 4 having a first surface side 6 and a second surface side 7 opposite the first surface side 6, by which the urinal insert element 1 can be placed on a urinal device (not shown in detail). The base body 4 is also shown with a plurality of openings 5 ​​extending from the first surface side 6 to the second surface side 7 through the base body 4, wherein the base body 4 is shown with, or consists of, plant-based cellulose sponge material 3. The base body 4 is also shown with a structure of fibers 2.

[0036] Fig. Figure 4 shows a further schematic cross-sectional view of a urinal insert element 1 for a urinal device according to an embodiment of the present invention. In particular, a urinal insert element 1 for a urinal device is shown, comprising a mat-shaped base body 4 with a first surface side 6 and a second surface side 7 opposite the first surface side 6, with which the urinal insert element 1 can be placed on a urinal device, and wherein the base body 4 has a plurality of openings 5 ​​extending from the first surface side 6 to the second surface side 7 through the base body 4, wherein the base body 4 is constructed from two compressed loofah sponge fiber braids 8, the compressed loofah sponge fiber braids 8 being arranged one above the other.The majority of openings 5 ​​in the superimposed loofah sponge fiber braids 8 result from the multitude of free spaces between the fibers 2 of the respective loofah sponge fiber braids 8. In this respect, it is conceivable that the basic body 4 shown is constructed from the two compressed loofah sponge fiber braids 8, with the loofah sponge fiber braids 8 being superimposed.Furthermore, in other embodiments not shown in detail, it is conceivable that the respective longitudinal fiber directions of the respective loofah sponge fiber braids 8 are twisted relative to each other at an interval between 5° and 90°, preferably at an interval between 10° and 90°, preferably at an interval between 25° and 90°, preferably at an interval between 35° and 90°, preferably at an interval between 45° and 90°, preferably at an interval between 65° and 90°, and preferably at an interval between 75° and 90°, so that the splash protection effect of the urinal insert element 1 is increased overall. In other words, the loofah sponge fiber braids 8 are not arranged parallel to one another, but rather twisted in such a way that a wide variety of overall structures with their individual openings 5 ​​can result.

[0037] Fig. Figure 5 shows a further schematic cross-sectional view of a urinal insert element 1 for a urinal device according to an embodiment of the present invention. In particular, a urinal insert element 1 for a urinal device is shown, comprising a mat-shaped base body 4 with a first surface side 6 and a second surface side 7 opposite the first surface side 6, with which the urinal insert element 1 can be placed on a urinal device, and wherein the base body 4 has a plurality of openings 5 ​​extending from the first surface side 6 to the second surface side 7 through the base body 4, wherein the base body 4 is constructed from two compressed loofah sponge fiber braids 8, the compressed loofah sponge fiber braids 8 being arranged one above the other.The majority of openings 5 ​​in the superimposed loofah sponge fiber braids 8 result from the multitude of free spaces between the fibers 2 of the respective loofah sponge fiber braids 8. In this respect, it is conceivable that the basic body 4 shown is constructed from the two compressed loofah sponge fiber braids 8, with the loofah sponge fiber braids 8 being superimposed.Furthermore, in other embodiments not shown in detail, it is conceivable that the respective longitudinal fiber directions of the respective loofah sponge fiber braids 8 are twisted relative to each other at an interval between 5° and 90°, preferably at an interval between 10° and 90°, preferably at an interval between 25° and 90°, preferably at an interval between 35° and 90°, preferably at an interval between 45° and 90°, preferably at an interval between 65° and 90°, and preferably at an interval between 75° and 90°, so that the splash protection effect of the urinal insert element is increased overall. A chamber 9 provided centrally in the base body 4 is also shown. The urinal insert element 1 is shown with an insert element 10. In particular, the base body 4 thus has an insert element 10 between the first and second surface sides 6, 7, which is shown inserted in the chamber 9.The insert element 10 can be selected, for example, from: fragrance element; cleaning element; fragrance and cleaning element. The base body 4 is also shown to be thinner at both lateral edge regions 11 than in a central region of the base body 4. This can be achieved, for example, by increased pressure when compressing the superimposed loofah sponge fiber braids 8. In this respect, the first and second surface sides 6, 7 are at least partially reinforced at these edge regions 11. Furthermore, the first and second surface sides 6, 7 are connected at least partially at these edge regions 11 of the base body 4 by means of a seam 12 formed by another material. The other material for forming the seam 12 can be selected, for example, from: cotton; compostable bioplastic; wood fibers; water-soluble material; metal; metal alloy; loofah fibers.The chamber 9 is formed by means of two spacer elements 13 provided between the first and second surface sides 6, 7. In further embodiments not shown in detail, however, it is conceivable that the chamber 9 is formed by the loofah sponge fiber braids 8 themselves as a result of processing steps to be carried out on them. For example, increased pressure can be exerted at the respective locations of the loofah sponge fiber braids 8 in order to partially indent them so that the chamber 9 is formed in the assembled state. The chamber 9, or the respective recesses in the loofah sponge fiber braids 8, can also be formed by cutting processes or the like. Furthermore, the base body 4 is shown with a handle element 14. The handle element 14 is shown in particular as a tab-shaped handle element 14.Such a handle element 14 can be advantageous for removing the urinal insert element 1 according to the invention from the urinal device after use. It can, for example, be provided on an edge area 11, as shown, so that it is not directly exposed to a stream of urine during use. All in the . Fig. 1, Fig. 2, Fig. 3, Fig. 4 to Fig. The base body 4 shown in Figure 5 can, in further embodiments not shown, also comprise plant-based cellulose sponge material 3, for example in the form of loofah sponge fiber meshes 8, which are impregnated with one or more active ingredients suitable, for example, for cleaning, disinfecting, and / or scenting, and / or which can increase the stability of the urinal insert element 1. The active ingredient can, in particular, be a biological cleaning agent or comprise a biological cleaning agent. The active ingredient can be selected from: compostable bioplastic; water-soluble material; organic plastic; inorganic plastic; beeswax; carnauba wax; soy wax; linseed oil; tung oil; wood oil mixture; biopolymers; chitosan; silane; siloxane; epoxy; acrylic. All of the Fig. 1, Fig. 2, Fig. 3, Fig. 4 to Fig.The base body 4 shown in Figure 5 can, in further embodiments not shown, also comprise at least one further material not shown. This further material can, for example, be selected from: compostable bioplastic; wood; water-soluble material; organic plastic; inorganic plastic; beeswax; carnauba wax; soy wax; linseed oil; tung oil; wood oil mixture; biopolymers; chitosan; silane; siloxane; epoxy; acrylic. It can, for example, be provided that the further material forms a kind of framework into which the base body 4 is fitted or at least partially attached. For example, a kind of frame structure can be provided, the shape of which corresponds to a respective insertion area of ​​a urinal device, wherein the plant-based cellulose sponge material 3 is then embedded or attached centrally in this frame structure.For this purpose, fastening elements can be provided, which can also be of organic origin, so that a completely compostable embodiment of the urinal insert element 1 according to the invention can result. 2025The plant-based cellulose sponge material 3 can, in further embodiments not shown in detail, be made from the following materials in addition to loofah plant material: Wood cellulose sponge (regenerated cellulose from wood pulp). This consists of decongested wood cellulose (for example, from beech, pine, or spruce). The pore structure can be created, for example, by freezing or foaming techniques. It exhibits good capillarity and allows water and air to pass through evenly. A bamboo cellulose sponge can also be provided. This can be made from bamboo fibers. It is very fine-pored, yet permeable.Since this material is also suitable for water filtration, as well as for biological media and cleaning purposes, its function can be considered sufficient for the aforementioned technical effects. A cotton cellulose sponge can also be used, which consists of pure cotton cellulose and can be chemically processed to provide sufficient porosity. In addition to a certain liquid absorption capacity, it can also be sufficiently open-pored to allow good flow. Sugarcane bagasse cellulose can also be used. This consists of residual fibers after sugar extraction and is rich in cellulose and hemicellulose. After foaming and drying, a highly permeable, sponge-like material is produced. Hemp cellulose sponge can also be used.This consists of disintegrated hemp fibers, which are a very durable material with good porosity. Flax / linen cellulose sponge can also be used. This is made from flax fibers combined with soluble cellulose. It has a uniform pore structure and allows good water and air circulation. Coconut fiber cellulose composite can also be used, which is made from a combination of a cellulose binding matrix and coarse coconut fibers. It is a porous, open-structured material ideal for flow and drainage purposes. Banana fiber cellulose foam can also be used. This can be made from the fibrous tissue of the banana plant, which develops capillary channels during drying. Paper cellulose sponge (for example, made from unbleached cellulose) can also be used.This can be produced mechanically, for example by foaming or chemically, and can have an open-pore structure.
