Description

The present invention relates to a catamenial product in the form of a tampon, to a method for producing a catamenial product, in particular in the form of a tampon, and to a kit comprising the proposed catamenial product.Catamenial products are known feminine absorbent hygiene products that occur in various forms. Most commonly used are sanitary napkins as panty liners and tampons. These products are made using synthetic materials. The use of disposable pads of synthetic materials and conventional sanitary napkins results in a substantial amount of waste and environmental impact. Moreover, some of the chemicals used in these products may present potential health risks. There is therefore an urgent need for a long-lived, more durable and ready-to-use alternative for catamenial products.Tampons are commercially known menstrual products which are introduced manually and / or through an applicator into the vagina of a person usually taking a menstrual person. The liquid is thereby guided through the outer layer into the interior of the tampon, so that the liquid absorption is constantly ensured without inhibiting the natural flow. Because of their cylinder-like shape, tampons are easy to insert into the vagina. The surface is often made of a smooth material and is partially textured by grooves to facilitate fluid ingestion. Such a method is disclosed, for example, in DE 20 2006 000 746 U1. When introduced into the body, the tampon has a certain strength which becomes more flexible in shape due to the absorption of body fluids, so that the latter is led out of the body with the aid of the withdrawal tape in a substantially larger, softer and more voluminous manner.Conventional tampons are discarded at this point, or incorrectly flush the toilet, which, due to the mass of menstruating persons, results in much waste and a high amount of plastic gets into the groundwater.Disposable pads are usually made of a blend of viscose and cotton fibers which are pressed into shape and subsequently processed. In this process, recourse is frequently made to a sheathing made of synthetic materials which are thus initially in close contact with the body of women and the environment for hours. These cannot be biodegradable, but must be disposed of or burnt. They thus represent an immensely high burden on humans and the environment. Therefore, it is desirable to have an alternative to the disposable product. Although there are also proposals for reusable tampons, as are disclosed, for example, in WO 95 / 13040. However, these have inherent disadvantages and are therefore not applicable.It is an object of the present invention to reduce the amount of waste relevant to catamenial products.This object is achieved with a catamenial product in the form of a tampon having the features of claim 1, with a method for producing a catamenial product having the features of claim 9 and with a set having the features of claim 10. However, the invention is not limited to the proposed embodiments. Rather, one or more features from the claims, the following description and / or the figures can be combined to form further developments of the invention. Also, the present claims are only a first approach to describing the invention. In contrast, claims are also proposed in which one or more features of the present claims are replaced and / or supplemented by one or more features of the present description or can also be deleted.A catamenial product in the form of a tampon is proposed, comprising at least one, preferably recyclable, in particular biodegradable, first material, which is absorbent in the dried state, wherein the first material can be washed repeatably at at least 90° C. while preserving a tampon-like form without losing its absorbent capacity, wherein the first material is preferably based on cellulose and / or viscose and comprises moisture-absorbing cavities, wherein wall structures of the cavities made of the first material are flexible under the influence of moisture.The catamenial product preferably comprises only a biodegradable first material. This allows reliable recycling. The biodegradable material is, for example, cellulose- and / or viscose-based. Both materials can also be readily deposited with catamenial residues present thereon such that the catamenial product can self-decompose under the influence of heat, oxygen and, optionally, pressure. The decomposition can be assisted by addition of suitable bacteria or adaptation of ambient conditions such as, for example, a temperature, a pressure, a humidity and / or others. In addition to a first material, there is also the possibility that at least one further, second material and / or also a plurality of additional materials are present. The second material may also be biodegradable. It is preferred that the biodegradable first material is that material which forms the cavities by means of wall structures. An additional, for example second material can serve to enable bonding or a strengthening of the position of hollow spaces. It is also possible for the second material to form a coating of the first material. The coating can be present completely or else only partially. By means of the coating, for example, a surface property of the first material can be adapted to the Menses liquid to be absorbed.A further embodiment of the invention provides that the catamenial product consists exclusively of biodegradable materials. This can relate, on the one hand, to the tampon as such. In addition, however, a material which surrounds the tampon, for example in a packaging, for example a plastic casing, can likewise be biodegradable. Furthermore, a tape which is fastened to the tampon can likewise consist of a biodegradable material. Preferably, the materials used for the tampon, the tape and also the packaging are matched to one another such that they can be subjected to the same recycling process, for example. It is preferably provided that at least the material of the tampon as well as of the tape are biodegradable together by adding suitable bacteria. It is preferred if the catamenial product consists only of biodegradable components.The catamenial product in the form of a tampon is preferably recognizable in that this shape of the tampon is already present at least partially at the time of removal from a package. The first material is preferably shaped into a contour designed in such a way that an elongate body, preferably a body which is at least partially approximately radially symmetrical, in particular a body which is cylindrical-like, is obtained. The body can also have a changing diameter, for example a conically similar elongate shape, at least in sections. The elongated shaped, in particular cylindrical-like shaped body has a thickness that is less than a length of the elongated shaped body. Preferably, the elongate shaped body comprises a dome. This dome avoids the formation of a circumferential edge. According to one embodiment, the dome can be made of the same material from which the other contour of the tampon is also substantially shaped. A further embodiment provides that at least a part of this dome is made of a different material. For example, the dome may be formed from one material which mixes with the other material and thus provides a transition from the dome to the elongate shaped body. A cylindrically shaped body need not be strictly cylindrical. Rather, it can also have a different thickness over its length. The thickness can, for example, change continuously from one end to the other end, for example lead to thickening or thinning. It is also possible for the elongate body to have an outer shape which, for example, is shaped in a wavy manner and / or which has shoulders, interruptions or other contour shapes. For example, this interrupts a uniform outer contour, in particular a strictly cylindrical contour. This interruption can extend over an entire circumference of the contour. There is also the possibility that only partial circumferential regions thereof are detected, but not a complete total circumference. Also, various configurations having different shapes may be provided.The moisture-receptive cavities preferably have dimensions such that the catamenial product to be receptive is introduced into the catamenial product. Preferably, the moisture-absorbing cavities have a structure which makes it possible to enable absorbency of the tampon thus formed. For example, the cavities can form capillaries which are capable of guiding the menses into the interior of the tampon by means of physical effects. The formation of capillaries which transport the menses can be influenced, for example, by means of a production process in such a way that capillaries change from the outside to the inside into the tampon, in particular change their diameter and / or their size, for example decrease and / or increase. A further embodiment provides that the capillaries can also widen again towards an interior of the tampon. In this way, the menses can be absorbed at the surface of the tampon, with the interior of the tampon permitting greater menses absorption by increasing capillaries. Preferably, the catamenial product is configured such that the first material used can act flexibly under the influence of moisture. For example, cavities can on the one hand become larger. On the other hand, the material itself can also swell and enable storage of the menses by means of the swelling. Preferably, the tampon exhibits reversible swelling behaviour when the menses are taken up. This is to be understood as meaning that, after cleaning the tampon at a temperature of at least 90° C., on the one hand, the shape of the tampon continues to be present. On the other hand, the menses can be completely rinsed out, so that during a subsequent drying process the swollen material contracts again. There is also the possibility, for example, that due to the material during drying the material also stiffens itself again compared to the swollen state.A further embodiment provides that the catamenial product in the form of the tampon is provided with the first material having a greater stiffness in the dried state compared to a moist state and a greater flexibility in the moist state compared to the dried state and having a first diameter in the dried state and a second diameter in the moist state, wherein the first diameter is smaller than the second diameter. This effect is repeatable, in particular even after a plurality of washing operations at 90° C. Thus, for example, it has been found that, when a first material made of cellulose and / or viscose is used, the tampon thus grown has still retained its shape and its property after 15 washing cycles.According to the invention, a catamenial product is also proposed, wherein the first material is at least one sponge. The sponge is preferably made of biodegradable material. With regard to the biodegradability, for distinguishing between biodegradable products on the one hand and plastics on the other hand, reference is made to a clarification within the scope of the disclosure, as can be seen, for example, from the publication "Viscose Fibers und Kunststoff", Position Paper of the Industrial Association Chemiefager e.V. (IVC) for defining plastics in the disposable plastics guideline, dated 24.2.2021. The references cited in the publication and the references cited therein show the difference between the article and the biodegradable material, as is also to be understood in the sense of the invention. For example, a viscose sponge produced from regenerated cellulose and water is optionally provided with color pigments. A cellulose sponge is produced, for example, from vegetable constituents such as wood and cotton. The sponge can be produced in various ways. It is further preferred that the sponge is a viscose sponge. In the production, regenerated cellulose and water are preferably used, optionally. Color pigments and, if appropriate, color pigments. Softeners when using moist material. Preferably, a method is chosen in which the pore size is adjustable. For example, the pore size can change over the thickness, for example increase from the outside to the inside and decrease again from the inside to the outside. In particular, a method for producing a sponge is chosen, in which it is ensured that no residues remain in the sponge, which residues are absorbed via the mucous membranes and have a harmful effect on health.According to one embodiment, the sponge has an open-pored surface. The open-pored surface enables the mouths to enter the sponge as well as be sucked into it. The sponge is preferably open-pored throughout. A further development provides that the sponge has a different pore size in an outer region compared to an interior of the sponge. For example, the Schwann has smaller pore sizes in the outer region compared to the interior.Furthermore, it is possible to use different sponges together. For example, these sponges may have mutually different pore sizes. The different sponges can lie in different configurations with one another as well as against one another, directly or indirectly, for example separated by another layer of another material, for example a biodegradable nonwoven.A further embodiment provides that the catamenial product is designed such that the first material is formed by means of hollow fiber, preferably by means of a compressed viscose hollow fiber. The use of a hollow fiber allows the interior of the fiber to be used as a volume to contain the menses. At the same time, the use of the hollow fiber enables pressing as well as expansion to be made possible by a change in the thickness of the fiber. When using a hollow fiber made of viscose, there is also the possibility that the menses ensure that the viscose itself likewise swells. This makes it possible for the viscose hollow fiber to utilize two effects: on the one hand, liquid absorption, for example via a capillary effect, in the interior of the hollow fiber and, on the other hand, the use of the material itself as a reservoir for liquid. Furthermore, the outer geometry of the hollow fiber can also have a liquid-conducting property, preferably due to the formation of the hollow spaces which can fill with liquid.Furthermore, it can be provided that the catamenial product is provided with a protective sheath. This protective sheath can serve, for example, as a direct packaging in order to protect the tampon on the one hand, for example against soiling. On the other hand, according to a further embodiment, this serves to extend the shelf life and thus the usability of the catamenial product. For example, this protective sheath can prevent moisture and / or liquid from directly entering and entering the first material and thus, for example, a suction effect leads to swelling of the catamenial product and thus its non-usability for the user.A further embodiment provides that the protective sleeve has a function for an unused catamenial product and for a used catamenial product. For example, the protective sheath secures the unused tampon directly, since it surrounds it in a liquid- and moisture-tight manner. If the unused tampon is removed from the protective sleeve, a used tampon can subsequently be repacked by means of the same protective sleeve. Preferably, the protective sleeve is designed such that not only a used tampon of the same original size but also another used catamenial product of different original size can be repackaged. The catamenial product used may be, for example, a tampon of other size. A further embodiment provides that the catamenial product to be repackaged can also be a napkin or another catamenial product of a different shape. For example, the protective cover has so much area that the catamenial product used can be wrapped more than just once. Preferably, the catamenial product used can be wrapped in a moisture- and liquid-tight manner by means of the protective sheath.Furthermore, it is preferred if the material of the protective sleeve is likewise biodegradable. A further development even provides that the material of the protective sheath dissolves in water at a temperature of 90° C. Such a protective sheath can be made, for example, as a bioplastic bag made of a combination of polyvinyl alcohol (PVAL), starch, glycerol and water. In this case, PVAL is responsible for the water solubility of the product. The polymer rejects most anhydrous solvents, is resistant to oils and fats, and can be filtered once dissolved in water without residual water. Such a material mixture can be reliably dissolved even at lower temperatures, for example at 80° C. Thus used pads stored in such a protective sleeve can also be placed in a container and then fed to 90°C laundry in a washing machine. During washing, the protective sheath dissolves without residue and the tampon remaining in the container is washed and cleaned accordingly. Bags such as the Invisible bag from Fa. can be used, for example. Individual Company, Hong-Kong, HK, https: / / www.individual-company.com, which classify it as hydro-biodegradable and then compostable according to ASTM D6400 and EN13432, respectively. However, other comparable bags can also be used, which can consist for example of saccharides, starch or another biodegradable material. For example, bags called H2OK, which were tested by the Italian laboratory of Materialsi Polimeric Ecocompatability-laboratory for environmentally compatible polymeric materials-(LMPE), can also be used. The manufacturer of these PVA-based bags is Medanos Claros HK Limited, #2302, 23 / F, Lee Garden Two, 28 Yun Ping Rd, Causeway Bay, Hong Kong, China. Hot water-soluble films for hot water starting from a release temperature of >45° C. again represent the problem. Sokufol Fiht GmbH, Industriestrasse 11-13, 65549 Limburg, based on PVOH, which can be used as bags for the used or unused pads.Preferably, the protective sheath prevents a discharge of menses from the protective sheath. This in turn prevents, for example, contamination by the menses contained in and on the used menstrual product. The protective sheath can have a resealable nature for this purpose, for example. According to one embodiment, it is provided that the protective sleeve has a predetermined opening for removing the still unused catamenial product. This opening can be prefabricated, for example. For this purpose, for example, a region of the protective sheath can have the resealable nature, for example by means of an adhesive surface.The protective sheath can have a bag-shaped form which can be closed again. For this purpose, a tab can be provided, for example, on the pocket-shaped form, which tab is used to pull the material of the protective sleeve around the used tampon after the latter has been inserted into the pocket-shaped form of the protective sleeve. The pocket-shaped configuration can then be liquid tightly sealed.According to a further configuration, the protective sheath can have a planar shape in which the used menstrual product is wrapped. It is preferably provided that respective side edges of the planar shape adhere to the material of the protective sleeve in such a way that the used wrapped-in of the menstrual product is stored in the protective sleeve in a liquid-tight manner. For this purpose, for example, an adhesion can be provided, in particular adhesive surfaces on the side edges. Upon contact of these adhesive surfaces with the remaining material of the protective sheath, a connection, preferably a liquid-tight connection, is then created. Such an adhesive surface can have, for example, a continuous adhesive application. Furthermore, a plurality of adhesive surfaces can be arranged one behind the other, which achieve a barrier effect with respect to moist or liquid in this way. Further, it is preferable that the used material providing the adhesive property is also biodegradable. The material having the adhesive property can be sprayed on, printed on or applied in another manner. This can be done in line form, in dotted form or in some other way.According to a further embodiment of the catamenial product, it is provided that this first material is provided with a sheath, to which preferably one end of a retrieval tape is fastened and preferably another end of the retrieval tape is fastened to the first material. In this way, the enclosure as well as the first material is secured together, for example. According to one embodiment, the sheath serves to protect the first material. Furthermore, according to a further embodiment, the casing can be configured for rapid liquid absorption and liquid transfer to the first material. Furthermore, it can be provided that the casing provides a particularly soft surface which makes it possible to introduce or use the catamenial product in a particularly skin-friendly manner. According to yet another embodiment, the cladding can also be used to stabilize the first material arranged in the cladding, at least with regard to its shape. For example, it can be provided that the sheath has a higher elastic property compared to the first material. For example, as a result of this or by other properties, a pressure can be exerted on the first material by means of the cladding. Preferably, the material of the enclosure and the first material are joined together. This can be effected, for example, by terminating fibers. At least one of the two materials is a fiber material or comprises fibers. The other material, on the other hand, is capable of bonding to the fibers, whether by adhesion, adhesion, entanglement of the materials, or in some other way. For example, the first material as well as the material of the cladding can each have fibers. A connection between the sheath and the first material can also be effected, for example, by engaging each other. Such a kind can be created, for example, by means of needle punching.The catamenial product may further comprise such a wrap, wherein the wrap comprises a knitted wrap, wherein the knitted wrap is preferably composed of a viscose fiber and / or the wrap comprises hollow fibers, preferably at least one layer of the wrap is formed of hollow fibers. An advantage of a stretched material is the possibility of being able to adjust a strength by the manner of scraping. On the other hand, a knitted casing also allows a binding to be made with the first material arranged in the casing. For example, a used thread and or fiber can be passed through the first material during the stretching process itself.A further embodiment of the invention relates to the production of the proposed catamenial products. For example, it is provided that the casing is produced and subsequently the first material is arranged in the casing. If the cover is a knitted cover, the arrangement can also be made possible in a continuous process. In this case, for example, the first material is supplied in the form of a cylindrical strand. Around this strand shape, the covering is arranged continuously, for example stretched. Subsequently, the material thus created can be cut and, if appropriate, supplied to a further shape. However, other approaches are possible to perform a continuous manufacturing process. During production, there is also the possibility that the material of the casing and or the first material alone or together are subject to a compressive load. On the one hand, this can be used to enable the respective materials to be inserted into one another. On the other hand, it is also possible to carry out a compression in such a way that a subsequent outer packaging protects the catamenial product at least against external contamination, preferably against moisture and or liquid damage. The outer packaging is preferably designed with a protective sleeve, as is also described in more detail above and below.According to a further concept of the invention, which can also be followed independently, it is proposed to provide a pack with catamenial products, a multiplicity of different catamenial products being jointly contained in this pack. Preferably, the proposed catamenial product is used. In this case, one configuration provides that at least some of the catamenial products are proposed catamenial products in the form of a tampon. In this case, tampons of different sizes can be arranged in this packaging. Preferably, all of these tampons are reusable in the manner described. However, they can also be produced differently or have different materials. A further embodiment provides that in addition to the proposed catamenial products, other catamenial products may also be included in the package. These may be, in particular, catamenial products having a form of napkin. According to a further development, this napkin can also be designed to be reusable, for example analogously to a basic production mode or a basic construction as described here with reference to the proposed catamenial products for a reusable tampon. Furthermore, according to a further embodiment, it is possible that one or more catamenial products in the package are only disposable products which have to be disposed of after the single application. The package can thus have a multiplicity of the most varied catamenial products, wherein, however, all packages have in common with one another that at least a portion, preferably the predominant number of catamenial products present therein, can be reused.According to a further aspect of the invention, a method for producing a reusable catamenial product which can be washed several times at 90° C. in the form of a tampon having a first material which is biodegradable, preferably having a first material as described above and also below, is proposed, wherein the first material is preswollen before it is produced ready for sale as a catamenial product. Such a procedure makes it possible for the first material to be highly compacted, in particular produced and / or transported in a maximally compacted manner, for example. By means of the high-compression process, the space required during transport is limited to a minimum. If, furthermore, an arrangement of the pre-compressed material in this way is selected which enables the best possible utilization of the available space of a packaging, waste of unused space and thus a transport effort on the whole can be reduced in this way. However, in order to make the pre-compressed material in this way usable within the scope of use, for example, a treatment with moisture and / or liquid is provided in the production process to form the catamenial product. This is done in a defined manner so that the first material only expands as intended. This pre-swelling can take place, for example, before as well as after a final processing step, in particular also subsequently to an envelope. After pre-swelling, there is the possibility that the liquid and / or moisture contained in the first material is removed again, for example via a drying process. Another configuration again provides that the catamenial product has a certain residual moisture. The material or materials used for the catamenial products are preferably designed in such a way that this residual moisture is not suitable for causing bacteria or other germs to develop or grow during storage, for example. For this purpose, for example, packaging can be carried out using a protective gas, which prevents such a packaging. Such a protective gas is, for example, nitrogen.A further idea of the invention provides that a set is present so as to be able to be assembled or put together ready for sale. The set comprises at least one catamenial product in the form of a tampon, preferably as described above or below and / or produced by a method as described above or below, and a container, preferably a bag, in particular a wash bag and / or a liquid-tight storage bag for the catamenial product, wherein the catamenial product is preferably made of biodegradable material, which is capable of being washed and reused multiple times at 90° C., and the container receives a plurality of catamenial products and stores them in the container. Preferably, the catamenial product is retained in a container when the catamenial product is washed in a washing machine, the container then being permeable to blood and wash water. Furthermore, a container can also be liquid-tight. For example, a first container, which is liquid-tight, and a second container, which is permeable to menses and wash water, may be used. Again, one embodiment provides that a container is used, which is liquid-tight on the one hand, but also permeable to wash water on the other hand.For example, a container can have a fixed shape, for example a container into which one or more menstrual products can be placed. The container can be a sphere, approximately forming a sphere as a polygon. Other geometries are also possible, for example oval, cylindrical, cubic, rectangular or other geometries. Angular edges are preferably dispensed with. Edges are preferably rounded or couplings are placed on the respective end, for example, in the case of a cylinder, so that rounded shapes are obtained. For example, this container can be reclosable and re-sealable, preferably reclosable and re-sealable in a liquid-tight manner. The container with fixed walls may be liquid-tight according to one embodiment. According to another embodiment, the container can be permeable to wash water. Thus, the container can have one or more passages, preferably a plurality of passages, through which the wash water can pass, in particular flow in and out. A further development provides that at least a first and a second side of the container are each permeable, preferably each via a plurality of passages. It is further preferred if the first and second sides are opposite one another. A further configuration provides that the first and the second side abut each other. Again, it can be provided that multiple sides have passages, preferably more sides have passages than sides without passages. It can also be provided that all sides have passages. It is also possible for at least one side, preferably a cover, to be arranged interchangeably, once without passages, once with passages. A further embodiment provides that at least one passage, preferably all passages of the container, can be opened and closed in a repeatable manner, in particular can be closed in a liquid-tight manner. For example, by displacing and arresting two parallel wall regions of the container that are displaceable relative to one another, one or more passages can be opened or closed. It is also possible for the container to have one or more devices which act like a respective valve and make it possible or block the ingress of wash water. The container can be formed not only angularly but also round, oval or in some other way.Furthermore, a reusable, washable tampon substantially consisting of a biodegradable absorbent or monomaterial, a moisture-absorbing and binding intermediate membrane, a finely structured outer layer and a withdrawal tape combined together in a form, preferably a conical-like form, is proposed.The absorbent material consists, for example, of a self-pressed or machine-pressed viscose filament yarn. It is preferred that the intermediate layer surrounding the core, preferably consisting of viscose, functions here as a moisture-binding membrane by a plush bond. A further embodiment provides that the tampon has an outer layer as a cover, preferably made of viscose, for protecting the core, which serves for easier insertion into the body. Alternatively, the outer layer can also comprise at least one of the following materials: cotton, hemp, batt, finette and / or (tricot) jersey. It is preferred for the tampon if the withdrawal string consists of the same biodegradable material, preferably viscose, as the core. The tampon is designed for reuse over several menstrual cycles. Furthermore, the tampon is available in various sizes and / or shapes to be selected to suit individual needs. The proposed tampon thus relates to a natural, washable and thus reusable tampon which is a more durable and ready-to-use alternative to conventional disposable tampons. The use of biodegradable materials and the possibility of reuse over multiple menstrual cycles reduces environmental impact and minimizes potential health risks. The tampon provides high wear comfort and allows for individual adaptation to the user's needs.Manufacturing Details:Outer Layer Cladding (Exemplary):• an R / L tubular knitted fabric made of, for example, Lenzing Lyocell yarn• Tubular knit as sheath (made on very fine circular or flat knitting machine E10 upwards, E24 (needles per inch)Intermediate layer (exemplary):• 330dtex viscose filament yarn on E24 a knitted R / L fabric is produced• Bramant hollow fiber as fiber composite (here: spun fiber)Various configurations and their respective composition of the materials will be discussed by way of example below. The dimensions, weights and orders of magnitude specified here are exemplary and show, for example, how different sizes of tampons can be realized, which can be reused. The respective details are therefore also to be understood as being accurate details by way of example. Other sizes with different dimensions and weights are also possible.During the period, an average of 5-80 ml of blood is lost daily. This broad range illustrates the relevance of various sizes of the pads designed for the individual needs of the menstrurists. A view of the absorbency of commercial tampons, cf. Table 1, represents guide values in the properties of these, with which it is important to orient itself in order to obtain the usual handling of the tampons: Table 1: Properties Generate. Tampons Table 1: Properties obtained.

The aim of this test phase is to optimize prototypes by determining the liquid absorbency of the respective quantities in the optimum ratio of the different materials to one another. For example, other factors such as wear feel, retention and stability of the tampon have also been taken into account. The materials were tested for their respective absorption capacity in relation to their own weight, cf. Table 2. The core gives the tampon stability which only allows comfortable insertion. The dimensions of the various tampons or of the individual components of the reusable tampon, which are specified in the following by way of example, make this possible. Table 2: Absorption capacity in relation to the own weight of the materials Table 2: Absorption capacity in relation to the own weight of the materialsSponge Sponge10 (g)60 (g)90 (g)6-foldHollow Fiber2,5 (g)25 (g)30 (g)10-foldKnitted Fabric2,5 (g)6,5 (g)8 (g)2.6 Times 2.6 Times,5Comparison: Tampon2,3 (g)8 (g)23 (g)3.4-foldFor each material component, the following have been calculated depending on the respective size: a) absorbency of the sponge=eweight of the sponge×absorbance capacity b) absorbency of the knitted fabric=eweight of the knitted fabric×absorbance capacity c) absorbency of the fiber=eweight of the fiber×absorbance capacity and d) absorbency of the sponge+absorbance capacity of the knitted fabric+absorbance capacity of the fiber=abouts absorbency of the tamponThe following Table 3 gives an overview of the results determined based on different dimensions corresponding to different tampon sizes. The absorption capacity is shown in Table 3 as a factor of the absorbency of the dead weight. The component sizes and resultant dead weights are shown below in Table 3. Table 3 Table 3The desired Receiving Capacity6101418Self-weight sponge60,31,80,42,40,42,40,53Dead weight knit fabric2,512,51,74,251,53,751,754,375Dead weight fiber100,220,343,40,88110Total total1,56,310,0514,1517,375The individual components can be put together, for example, by first defining the own weights of sponge and knitted fabric, and determining the capacity of the partial lamp present in this way from this. If an average receptivity for a variable from Table 1 is targeted, the receptivity still to be made available by the fiber can then be determined therefrom. By means of this, with knowledge of the absorption coefficient of the fiber, the intrinsic weight of the fiber to be used in the dry state can be determined. This shows an exemplary way of how a design, but also an optimization of a construction of a reusable tampon of biodegradable materials is possible with the addition of known data from known disposable tampons. If, for example, two components are specified, it is possible to infer the third component of the reusable tampon from this.Design Examples ISize XS of the tampon6,3 The tampon was found to have the following capacity: 1.8 g+2.5 g+2 g=6.3 g of broken up onto the respective components:• a) sponge: dimensions (in cm): 4.5(b)×0.75(t)×0.75(h), with b: width, t: depth, h: height of dead weight 0.3 g (in the dry state)• b) Knitted fabric: dimensions (in cm): 5(b)×18(l) where b: width, l: length of dead weight 1 g (in the dry state)c) Fiber:Total weight 2 g (in the fully sucked state) -> Eigengewicht weight 0.2 g (in the dry state)Size S of the tampon10 g of absorbency of the tampon is as follows: 2.4 g +4.25 g +3.4 g = 10.05 g a) sponge: measure (in cm): 5(b)×1(t)×0.5(h) inherent weight 0.43 g (in the dry state) b) knitted fabric: measure (in cm): 5(b)×18(l) inherent weight 1.7 g (in the dry state) c) fiber:Total weight 3.4 g (in the fully aspirated state)→ Eigengewicht weight 0.34 g (in the dry state)Size M of the tampon14 g of the tampon absorbency is as follows: 2.4 g + 3.75 g + 8 g = 14.15 g a) sponge: measure (in cm): 4.5(b)×1(t)×0.5(h) inherent weight 0.4 g (in the dry state) b) knitted fabric: measure (in cm): 5(b)×18(l) inherent weight: 1.5 g (in the dry state) c) fiber:Total weight 8 g (in the fully sucked state) -> Eigengewicht weight 0.8 g (in the dry state)Size L of the tampon here with an exemplary calculation pathAbout 18 g Absorbency of the tampon: 3 g + 4.4 g + 10.8 g = 17.8 g a) Sponge: Dimensions (in cm): 4.5(b) × 1(t) × 0.7(h) Inherent weight 0.5 g b) Knitted fabric: Dimensions (in cm): 5(b) × 18(l) Inherent weight 1.75 gSince the knitted fabric can absorb 2.5 times its own weight, 1.75 g×2.5=4.4 g of absorbency for the knitted fabric is obtained. When the absorption capacity of sponge and knitted fabric is then calculated together, the result is: 3 g+4.2 g=7.2 g. A desired absorbency of the tampon should be about 18 g total absorbency, so that, starting from the determined absorbency capacities of each sponge and knitted fabric, the absorbency of the fiber can be deduced: 18 g-7.2 g=10.8 g. Since the fiber can absorb 10 times its own weight, it is considered that 1g×10=10g of absorbency. The result is thus obtained for the fiber which is given in c).c) Fiber:Total weight 10 g (in the fully sucked state) -> Eigengewicht weight 1 g (in the dry state)Design Examples IIBy way of example, a further procedure for designing a reusable tampon will be discussed below. A tampon M is a measure of other tampons so that material components are consistent in percentage sizes. For this purpose, the values determined for the tampon size M are transferred in relation to the various tampon sizes XS, S and L. For this purpose, for example, the following formula system and the following calculation methodology: a) Determination of the respective percentages according to the following formula weight of the material: dry weight tampon×100=content of weight in % b) The weights of the individual components of the tampon of size M having a capacity of 14 g in the dry state are added:0.4 g + 0.8 g + 1.5 g = 2.7 gc) Percentage content of the material components in the tampon M for sponge 0.4:2.7×100=14.8% fiber 0.8:2.7×100=29,6% knitted fabric 1.5:2.7×100=255.6% d) The absorbency of the tampon M is 14 g, divided on the basis of the percentages, the following component absorbency results:Sponge 14.8%=2.1 gFiber 29.6% = 4.1gKnit 55.6% = 7.8gThe calculation steps will not be described in detail below. The following ratios are obtained:Size XS of the tampon absorbency of tampon XS is 6 g, divided into sponge 14.8%=0.8 g fiber 29.6%=1.8 g knitted fabric 55.6%=3.3 gSize S of the tampon absorbency of tampon S is 10 g, divided into sponge 14.8%=1.5 g fiber 29.6%=3 g knitted fabric 55.6%=5.6 gSize M of the tampon absorbency of tampon M is 14 g, divided into sponge 14.8%=2.1 g fiber 29.6%=4.1 g knitted fabric 55.6%=7.8 gSize L of the tampon absorbency of tampon L is 18 g, divided into sponge 14.8%=2.6 g fiber 29.6%=5.3 g knitted fabric 55.6%=10 g component absorbencyFrom the thus determined absorption capacities of the individual components, it is in turn possible to convert to the dry weights of the individual components. For this purpose, too, the size M of the tampon is set as a scale, this tampon having 14 g absorbency. This leads to the following conversion, based on the respective capacity of individual variables, as follows: 6 g corresponds to 42.9% 10 g corresponds to 71.4% 14 g corresponds to 100% 18 g corresponds to 128.6%The calculation of the individual material components in dry weight takes into account the relationship determined for the size M of the tampon:2.7 g dry weight comprises 14 g liquid.The two formulae below are used to determine the respective dry weight of the individual components from this: a) dry weight×per cent=de dried weight factor b) material in %×de dried weight factor=de dried weight of the material componentsFor the respective different tampon sizes, the exemplary composition for the production results therefrom as follows:Tampon XS 2.7 τ 0.429 = 1.15 g knit: 55.6% × 1.15 g = 0.64 g becomes 0.6 g fiber: 29.6% × 1.15 g = 0.34 g becomes 0.3 g sponge: 14.8% × 1.15 g = 0.17 g becomes 0.2 gTampon S 2.7×0.714=1.9 g / / (2.1×0.714=1.5) knit fabric: 55.6%×1.93 g=1.07 g becomes 1 g fiber: 29.6%×1.93 g=0.57 g becomes 0.6 g sponge: 14.8%×1.93 g=0.28 g becomes 0.3 gTampon M 2.7×1=2.7 knit: 55.6%×2.7g=1.5g becomes 1.5g fiber: 29.6%×2.7g=0.79g becomes 0.8g sponge: 14.8%×2.7g=0.39g becomes 0.4gTampon L 2.7×1.28=3.47 g / / (2.1×0.714=1.5) knit: 55.6%×3.5 g=1.94 g becomes 2 g fiber: 29.6%×3.5 g=1.04 g becomes 1 g sponge: 14.8%×3.5 g=0.51 g becomes 0.5 gThese are thus only two possibilities which show by way of example how the design of a proposed tampon can be adapted on the basis of already existing tampon sizes and thus to the usual behavior and selection of the users.Even if this assumes idealised assumptions in each case, the calculation methods make possible an initial design which can then be adapted, for example, by tests and tests.Moreover, the reusable tampons produced in this way have been tested for their multiple use in different ways, for example also microbiologically. While some series of tests on the durability had a focus on the multiple washing after each use, in particular also on different multiple washing, and thereby aimed at the outer and inner durability of the tampon treated in this way, for example, microbiological investigations were also carried out in order to show which washing processes actually permit a safe re-use and which do not. This will be discussed below.Results of microbiological testing: in order to ensure that the proposed tampon is to be used without risk after use or after the washing cycle, various microbiological tests have been carried out by the applicant. With these tests, the bacterial cultures of the pads have been tested directly after use with a pad used after various washing cycles and with washing agent. The pads were cut open in the middle for the tests, and a sample was taken from each of them. The respective sample was coated onto a culture medium. Important results from the microbiological tests below:Test Result 1: Pad used, washed manually with cold water (comparative sample)CULTURE:Micrococcus s., about 100 CFU (micrococci are skin and environmental germs of low virulence. Very rarely are foreign body infections, for example on plastic material)Coagulase-negative staphylococci about 100 CFUEscherichia coli 10 CFUVaginal floraTest Result 2: Tampon, washed manually with cold water and washed at 90° CelsiusCULTURE:NO growth of bacteriaThe user of such a catamenial product is thus able to be re-used by manual washing and corresponding washing at temperatures at 90° C. Also, the washing at high temperature can be carried out manually. Thus, the water may be heated to the desired temperature in a pot, for example on a cooker, via a water cooker or by some other heating means. Temperature control can be effected with a suitable thermometer, which comprises a measurement range which also exceeds 100° Celsius, for example with a food thermometer such as a meat thermometer. Boiling water can also be used, i.e. water which is heated to 100° C. or more.Tests have shown that typical 90° washing with a washing machine is sufficient to reduce a biological load of the used tampon such that its re-usability is subsequently made possible without problems. No detergent was added in these tests. Washing machines were tested with a cooking wash program at 90 and 95° Celsius, respectively, the cooking wash program duration of which was 1⁄2 hours or more. The tests have also shown that washing with cold water alone is not sufficient to be able to reduce a load on the tampon used to such an extent that it can also be reused from a hygiene point of view.In addition to the possibility of using a cooking laundry program provided in conventional washing machines, which is usually associated with a temperature of at least approximately 90° or more Celsius, tests have likewise taken place which tested machine washing with a special washing program and showed that subsequent reuse of the tampon is also possible if a conventional cooking laundry program is not used. It is thus possible to wash the tampons for a certain first time at 90° and more Celsius in order to ensure that bacteria, germs and others are killed. Washing out in turn can subsequently take place at a second, lower temperature. It is also possible to first operate the wash-out at a lower temperature and subsequently use a cooking wash temperature. The time period of the washing out at a lower temperature can be longer here, but also shorter than the time of the cooking washing.It is also possible to wash the used tampons at a temperature below 90° C. In this case, it is important that the temperature is maintained for such a time that germs as well as bacteria are washed out sufficiently and are caused to die to such an extent that they are harmless during a test of the used and reused tampons.One embodiment provides for using a 60° Celsius wash cycle, wherein no ecoprogram of a washing machine is used here. The latter generally has too short a washing time. However, the problem with using a 60° Celsius wash cycle is that it is not reliably actually always 60° Celsius reached in the washing program. This is washing machine dependent. It has been found that at 60° C., it is possible, with a sufficiently long exposure time and rinsing time, to also be able to clean pads to such an extent that they can be reused.Another possibility for enabling used pads to be cleaned is to use washing agents. Thus, a wide variety of so-called hygiene detergents exist, which are to be used at 30° C. However, these detergents are in question whether adequate disinfection and cleaning is actually achieved. On the other hand, it is at least necessary to perform sufficient washing after use of the detergent with clear water in the washing machine. Since the hygiene detergents contain components which, if they remain in the tampon, are liable to be taken up via the mucosa when the user is used again, this danger is to be avoided by means of a sufficient rinsing of clear water.It is also possible to use a wash program at 40° C. and a washing agent which contains wash bleach. As studies show, it is possible to allow sufficient safety at least with respect to viruses, cf. Michael Heinz et al., "Evaluation of the virucidal performance of domestic laundry procedures" in International Journal of Hygiene and Environmental Health, Volume 213, Edition 5, September 2010, pages 334-337, https: / / doi.orq / 10.1016 / j.ijheh.2010.06.003. However, here too, a sufficient washing operation with clear water is necessary in order to avoid undesired portions, among other things, of the washing agent remaining in the tampon to be reused.A further possibility, which can also be used in combination with the preceding washing possibilities, is the use of microwaves. Thus, moist, preferably washed, pads can be placed in a microwave and treated. By adjusting the strength of the microwaves and the duration of the microwave treatment, even any germs or bacteria still present can be destroyed. It is also possible that prewashed pads which have been rinsed out are treated by means of microwaves before they are fed to a washing cycle in the washing machine. It is also possible to follow the treatment with microwaves after the washing cycle in the washing machine.Drying of the cleaned tampon can be done in air, for example at the clothes line. The drying location should, however, be chosen so as to avoid subsequent dirt from dust or others.In order to ensure freedom of the user for the use of his preferred cleaning procedure, the proposed reusable pads are designed to reliably survive multiple washes at at at least 90° Celsius.It is preferred to arrange the pads to be washed in a wash container such as a bag. This allows the pads to be washed without being subject to damage by the washing drum due to the machine washing, by wash washed with buttons, hooks or others, for example.Further advantageous embodiments are evident from the drawing below. The individual features shown here in individual figures are, however, not limited to the respective configuration. Rather, one or more features from one figure can be combined with one or more features from another figure to form a further configuration. Furthermore, the solutions shown in the respective figures can be considered per se. They are preferably to be understood as exemplary configurations, but are not intended to represent a restriction as such. The following are shown: FIG. 1 shows a first tampon, essentially consisting of an absorbent body, FIG. 2 shows a second tampon, essentially comprising an absorbent body and a wrapper, FIG. 3 shows a third tampon, essentially comprising an absorbent body, a fibrous material and a covering with plush, FIGS. 4, 5 and 6 show a fourth tampon having two tubular, crossedly arranged absorbent bodies which are surrounded by a knitted casing having a viscose fiber, FIG. 7 shows a fifth tampon made of a fibrous material and a sheath, FIG. 8 shows an exemplary dimension of a possibility of a wrapping using the example of a cut pattern representation for the respective above tampon sizes XS, S, M and L, FIG. 9 shows a sixth tampon made of a fibrous material and a reinforced casing, FIG. 10 shows a seventh tampon with a suction core which can be wrapped with a wrapping shown by way of example, FIGS. 11 aand 11 b show an eighth tampon from the outside and once in cross section.FIG. 1 shows a first catamenial product 1 in schematic view in the form of a first tampon 2. an absorbent body 3 consists of a viscose sponge as first material, which is produced without plasticizer and thus hardens in a dry state. A return ribbon 4, preferably likewise made of viscose, is fastened to the absorbent body 3, which facilitates extraction. The return strap 4 can be fastened in the first material, for example, by a first and a second end 5, 6. The tampon shape of the first catamenial product 1 schematically shown here has an approximately cylindrical-shaped body 7 with a first tampon end 8 which is dome-shaped. At an opposite second tampon end 9, which is shown here as being approximately smooth as a vertical section to a longitudinal axis of the tampon shape, unlike the illustration of FIG. 1, a dome-shaped closure can also be provided in which the withdrawal string 4 is fastened. The first material 11, consisting of a sponge 12, has an open-pore surface 13, wherein the individual pores 14 are schematically indicated. The pores 14 are irregularly and non-uniformly distributed due to the manufacturing process. However, a pore size can be at least influenced by the production process, preferably also adjusted with regard to an average size. The pore 14 forms a cavity 15, wherein the first material 11 of the sponge forms wall structures 16 surrounding the cavity 15.FIG. 2 shows a second catamenial product 17 in the form of a second tampon 18. a second absorbent body 19 shown here likewise has a viscose sponge, which is produced without plasticizer and thus hardens in a dry state. Arranged around the second absorbent body 19 is a casing 20, here shown as a casing 21, preferably knitted from a viscose fiber, which simplifies the insertion, since it offers a supple surface. A return strap 22, preferably made of viscose, is fastened to the sheath 20 in the form of the knitted sheath 20, which facilitates the extraction. The second tampon 18 is shown in a dry state having a diameter D1. The intake of menses by the second tampon is indicated, which leads to a change in the volume of the second tampon. This can be determined by an increase in thickness to a diameter D2. In comparison between the second tampon in the dry state and in the moist state, an increase in volume is also associated with a greater flexibility of the second tampon in the moist state.FIG. 3 shows a third tampon 23 in schematic view, essentially comprising a third absorbent body 24, preferably a sponge, a fibrous material 25 and a covering 26 with plush. The fibrous material 25 surrounds the absorbent body 24, wherein the fibrous material 25 is again surrounded by the casing 26. A withdrawal tape 27 is also present on the third tampon 23. The withdrawal tape 27 can extend, for example, with a longer tape region within the third tampon 23, preferably also extend one or more times around the third absorbent body 24 and / or the fibrous material 25. As shown, the third absorbent body 24 is completely surrounded by the fibrous material 25. It is likewise possible for one end of the absorbent body 24 to terminate together with an end region of the fibrous material 25 and for the absorbent body 24 to be visible outwards as a result. The third tampon 23 is produced, for example, by introducing the fibrous material 25 and the third absorbent body 24 into the prefabricated casing 26. The fibrous material 25 may be produced in the form of one or more fibers of a material. However, various types of fibers can also be connected to one another, for example made of different materials. Thus, the fibrous material 25 can first be formed around the third absorbent body 24, before both are then introduced into the prefabricated casing 26. It is likewise possible to arrange another method of production, for example first the third absorbent body 24, in order to arrange the fibrous material 25 around the latter and then arrange the casing around the third absorbent body 24 and the fibrous material 25. However, other methods of production are also possible. Preferably, all components are at least largely prefabricated before they are connected to one another. This allows a continuous manufacturing operation. For this purpose, feed lines may be present, one component of each feed line being fed to the tampon manufacturing process. However, it is likewise possible to first produce at least one component of a tampon directly on site during a continuous production process. The fibrous material 25 forms cavities with its fiber or fibers, wherein the material of the fibers in this case forms wall structures. Although these differ from those of a sponge, they preferably also provide a holding and binding structure.FIGS. 4, 5 and 6 show a fourth tampon 34 in schematic view:the fourth absorbent body 28 consists of two tubes 29 intersecting one another and consisting of two parts;the sheath 30 of the tube 29 comprises a knitted viscose fiber;filling it with a very strongly pressed hollow fiber, in particular a bramant hollow fiber 31, in order to suck up and bind the liquid;Bands 32, preferably made of viscose, are fastened to all four ends, and are brought together to form a return band 33;During insertion, the finger of the finger gives the required stability.FIG. 7 shows a fifth tampon 35 in schematic view:the fifth absorbent body 36 as the first material consists of a very strongly pressed hollow fiber, preferably a bramant hollow fiber;Around the fifth absorbent 36 is a sheath 37 knitted from a viscose fibre, which simplifies the insertion because it provides a supple surface. In this embodiment, the casing 37 completely encloses the fifth absorbent 36 so that the fifth absorbent 36 is not visible from the outside;A returning ribbon 38, preferably made of viscose, is fastened to the sheath 37 so as to simplify the extraction.FIG. 8 shows an exemplary dimension of a possibility of a wrapper 39 using the example of an exemplary sectional pattern representation for respective tampon sizes XS, S, M and L. In this case, the wrappers have the following dimensions, but are not limited thereto:XS: a=15 mm, b=45 mm, c=5 mm, d=20 mmS: a=20 mm, b=45 mm, c=5 mm, d=20 mmM: a=25 mm, b=50 mm, c=5 mm, d=20 mmL: a = 30 mm, b = 50 mm, c = 5 mm, d = 20 mmFIG. 9 shows a sixth tampon 40 in schematic view:the sixth absorbent body 41 consists of a very strongly pressed hollow fiber, preferably a bramant hollow fiber;around the sixth absorbent body 41 is a sheath 42 knitted from a viscose fibre, which simplifies the insertion because it provides a supple surface;The sheath 42 is reinforced at the upper end 43, for example by another binding 44. This can produce, for example, an additional stability required. The reinforcement 45 can also be produced by other means, for example by means of multilayers, an additional material, another material and / or by means of compaction;A returning ribbon 43, preferably made of viscose, is fastened to the sheath 42 so as to simplify the extraction.FIG. 10 shows an example of a wound seventh tampon 47 in schematic view:a seventh absorbent body 47 consists of a sponge, preferably a viscose sponge, which is produced without softener and thus hardens in a dry state;a sheath 48 consisting of uncolored biobaum is disposed around the seventh absorbent member 47;This casing 48 not only comprises the seventh absorbent body 47, but has a tail 48 on one side, which is for example 5 to 7 cm long and preferably falls down to a height of 2 to 3 cm. Other dimensions and a different section of the tail-out are also possible;a return strip 49 is preferably fastened to the sheath 48;the tail 50 is bound around the seventh absorbent body 47, is quasi wound and fastened with the return ribbon 49;The wound seventh tampon 46 can be cut as shown, but also differently. In particular, the shape of the enclosure 48 may also be different than illustrated. Likewise, the tail 48 can also be fastened in another way, for example without using the return ribbon 49.FIGS. 11 aand 11 b show an eighth tampon 51 in schematic view. Centrally, a sponge is arranged as the first material as the eighth absorbent body 52, surrounded by a non-woven material 53, for example. Both are surrounded by a sheath 54. In the case of this eighth tampon 51, the sponge, like the nonwoven material 53, extends as far as an end 54 of the eighth tampon 51, so that sponge, like the nonwoven material 53, can be seen there at this end 54, as is shown in FIG. 11 b.List of reference characters1 first catamenial product 2 first tampon 3 absorbent body 4 withdrawal tapes 5 first end of withdrawal tape 6 second end of withdrawal tape 7 cylindrically shaped body 8 first tampon end 9 second tampon end 10 dome-shaped termination 11 first material 12 sponge 13 open-pore surface 14 pores 15 cavity 16 wall structure 17 second catamenial product 18 second tampon 19 second absorbent body 20 casing 21 knitted casing 22 withdrawal tapes 23 third tampon 24 third absorbent body 25 fibrous material 26 casing of first material 27 withdrawal tapes 28 fourth absorbent body 29 hoses 30 casing of a hose 31 bramant hollow fiber 32 tapes 33 withdrawal tapes 34 fourth tampon 35 fifth tampon 36 fifth absorbent body 37 casing 38 withdrawal tapes 39 casing 40 sixth tampon 41 sixth absorbent body 42 Sheath 43 Upper end 44 Bond 45 Reinforcement 46 Seventh tampon 47 Seventh absorbent 48 Sheath 49 Withdrawal tapes 50 Tail 51 Eighth tampon 52 Eighth absorbent 53 Nonwoven material 54 Sheath 55 End a, b, c, d Dimensions D1 First diameter of the tampon in the dry state D2 Second diameter of the tampon in the wet stateReferences included in the specificationThis list of documents cited by the applicant has been produced in an automated manner and is only included for the better information of the reader.
