Abstract
Description
[0001]
[0002] Cleaning tablet
[0003] The present invention relates to a cleaning tablet for cleaning at least one hollow body, wherein the
[0004] Cleaning tablet, preferably powdered, microcrystalline cellulose as a binder. Furthermore, the application relates to the use of such a cleaning tablet for cleaning a hollow body and a method for producing such a cleaning tablet. Such cleaning tablets are already known from the prior art. For example,
[0005] DE 100 45 977 A1 describes a process for cleaning hollow bodies in which cleaning-active substances are present in the form of compacted shaped bodies, i.e. tablets.
[0006] The cleaning process is essentially carried out by the active cleaning substances, which dissolve dirt through chemical reactions. For this purpose, the cleaning tablet is dissolved in a liquid, such as water. This solution must then be absorbed into the hollow body to achieve a cleaning effect. The exposure time can range from a few minutes to several hours.
[0007] The object of the invention is to provide an improved cleaning tablet for cleaning hollow bodies, which in particular enables faster cleaning. This object is achieved by the features of independent claim 1.
[0008] According to the invention, it is therefore provided that the cleaning tablet comprises glass powder and / or ceramic powder for the mechanical removal of contaminants.
[0009] The cleaning tablet according to the invention is also dissolved in a small amount of liquid, such as water, contained in the hollow body. The hollow body is then swirled and / or shaken, causing dissolved particles of the cleaning tablet to move within the hollow body. The glass powder particles then contact the surfaces of the hollow body, mechanically removing contaminants from the surface.
[0010] This allows hollow bodies to be cleaned significantly faster, for example, within 0.5 to 1.5 minutes. It can also be provided that the microcrystalline cellulose also causes mechanical removal of contaminants.
[0011] Hollow bodies, within the meaning of the present application, are understood to mean objects with one or more openings which form or have a hollow space. Examples include mugs, cups, bowls, bottles, vases, and jugs. For the purposes of the present application, ceramic powder is understood to mean a powder made of ceramic material. According to the invention, ceramic material is an inorganic, non-metallic material which is fired, or in other words sintered, during its production to produce a hard, water-resistant product.
[0012] In other words, the ceramic material according to the invention is sintered ceramic and / or oxide ceramic. The ceramic powder preferably has a vitrified outer surface.
[0013] Examples of such ceramic materials within the meaning of the invention are appropriately fired clay, porcelain or stoneware. The invention also provides for the use of a
[0014] Cleaning tablet intended for cleaning a hollow body.
[0015] With regard to a method according to the invention, it is provided that at least one component, preferably all components, of the cleaning tablet are in powder form, wherein the components of the cleaning tablet are mixed and then compressed into a tablet. Known tablet presses can be used for this purpose.
[0016] Further advantageous embodiments of the invention are defined in the dependent claims.
[0017] It can be provided that the weight proportion of microcrystalline cellulose in the cleaning tablet is between 20% and 95%, preferably between 25% and 35%.
[0018] By using a correspondingly high proportion of microcrystalline cellulose, sufficient binding of the.'
[0019] Cleaning tablets can be guaranteed. If the weight percentage of microcrystalline cellulose is too low, such as 10% in the prior art, the cleaning tablets would dissolve immediately upon contact with a liquid, which is undesirable.
[0020] In addition, with higher weight proportions of microcrystalline cellulose, the mechanical removal of soiling via the microcrystalline cellulose can be increased and thus the cleaning effect can be improved.
[0021] The particle size of the microcrystalline cellulose can be between 50 μm and 300 μm. Preferably, cellulose of the PH-101 or PH-102 type is used.
[0022] Preferably, it can be provided that the weight proportion of the glass powder and / or the ceramic powder in the
[0023] Cleaning tablet between 5% and 50%, preferably between 14% and 28%.
[0024] This ensures that after dissolving the
[0025] Cleaning tablet contains sufficient glass and / or ceramic particles to achieve the desired cleaning effect.
[0026] It can also be provided that the glass powder and / or the ceramic powder has a particle size between 30 μm and 800 μm, preferably between 150 μm and 300 μm.
[0027] The appropriate particle size allows for the best possible removal of contaminants when the glass and / or ceramic particles impact the surfaces of the hollow body. The glass and / or ceramic powder may be in crushed form. This means that the glass and / or ceramic particles have an irregular, sharp-edged shape.
[0028] Alternatively or additionally, the particles of the glass and / or ceramic powder may also be in the form of glass and / or ceramic beads. This means that the glass and / or ceramic particles are rounded toward the outside, preferably essentially spherical.
[0029] In both of the above-mentioned grain shape variants, it is advantageous for the grains of the glass or ceramic powder to be completely surrounded by a vitrified surface. This is naturally always the case with glass powder. With crushed ceramic powder, this can be ensured by conducting the firing process after the material has been crushed or painted. In any case, the vitrified surface provides good resistance to acids.
[0030] According to a further embodiment, the cleaning tablet may comprise a surface-active cleaning agent, preferably in powder form.
[0031] In addition to mechanical removal, the surface-active cleaning agent can also be used to chemically remove surface dirt. In particular, the surface-active cleaning agent can be designed to dissolve grease.
[0032] The surface-active cleaning agent can therefore provide an even more thorough cleaning. Preferably, the weight proportion of the cleaning agent in the cleaning tablet is between 1% and 50%, preferably between 8% and 17%. This ensures that
[0033] The cleaning tablet must contain sufficient cleaning agent to enable sufficient chemical dissolution of soiling. The cleaning agent can be a commercially available dishwashing detergent, such as that used in dishwashers. The cleaning agent can therefore contain, in particular, sodium carbonate, sodium percarbonate, tetrasodium l-hydroxyethane-1,1-diphosphate and / or various alcohols. Other ingredients are also conceivable.
[0034] The cleaning tablet may contain a descaling agent, preferably in powder form, which is preferably at least one acid, particularly preferably at least one fruit acid. The descaling agent can be used to specifically dissolve limescale deposits in addition to the mechanical abrasion caused by the glass and / or ceramic powder.
[0035] The descaling agent can, in particular, be a fruit acid, for example citric acid, lactic acid, orange acid, and / or grape acid. It can also be provided that the descaling agent is a combination of several different fruit acids. The descaling agent can also be in powder form, with a particle size between 1 μm and 1000 μm being possible. It can further be provided that the weight proportion of the descaling agent in the cleaning tablet is between 1% and 40%, preferably between 7% and 18%.
[0036] This ensures that the cleaning tablet contains sufficient descaling agent to effectively remove limescale.
[0037] In connection with the descaling agent, another major advantage of using glass powder and / or ceramic powder becomes apparent. For example, if an unfired mineral powder, such as that already frequently used in cleaning tablets, were intended for the mechanical removal of dirt, this unfired mineral powder would be attacked by the descaling agent, especially by the acid, such as fruit acid. This would significantly reduce the cleaning effect of the cleaning tablet.
[0038] Glass, on the other hand, is resistant to the descaling agent, which means that if a descaling agent is provided, no complications arise. Ceramics within the meaning of the present invention are also resistant to the descaling agent due to the firing or sintering process. According to a further embodiment, the cleaning tablet can comprise soda, preferably powdered soda. The soda reacts upon contact with a liquid, especially water, and thus leads to the rapid disintegration of the cleaning tablet. In addition, the soda can also have a cleaning effect, for example, by dissolving grease.
[0039] The soda can be regular food soda.
[0040] Preferably, the proportion by weight of the soda in the cleaning tablet can be between 1% and 60%, preferably between 15% and 22%.
[0041] This ensures that the
[0042] Cleaning tablet completely and in the desired
[0043] speed decays, i.e. dissolves, is .
[0044] A powdered formulation of the components of the cleaning tablet, microcrystalline cellulose, glass powder, cleaning agent, descaling agent and / or soda, is advantageous in that a uniform distribution of the particles of the components can be achieved after dissolving the cleaning tablet.
[0045] In addition, the powdered form makes it easier to produce the cleaning tablet.
[0046] The specified weight proportions of the cleaning tablet components enable an ideal composition of a cleaning tablet, optimizing the cleaning effect of both the individual components themselves and the cleaning effect of the entire cleaning tablet. The cleaning tablet does not have to contain all of the components listed here and / or may also contain other, not explicitly mentioned components in addition or as an alternative.
[0047] The cleaning tablet can advantageously have a weight between 0.5 g and 4 g, preferably between 1.5 g and 2.5 g. Furthermore, the cleaning tablet can have maximum dimensions between 5 mm and 20 mm, preferably between 7 and 11 mm, in length, width, and / or height.
[0048] Further details and advantages of a preferred embodiment of the invention are explained in more detail below with reference to the description of the figures and the drawing. Figure 1 shows a schematic representation of a cleaning tablet according to the invention.
[0049] Fig. 1 schematically shows a preferred embodiment of a cleaning tablet 1. The cleaning tablet 1 has a cylindrical shape. However, the shape of the cleaning tablet 1 can, in principle, be chosen arbitrarily.
[0050] The cleaning tablet 1 comprises powdered microcrystalline cellulose 2, a glass powder 3, powdered cleaning agent 4 in the form of a dishwashing detergent, powdered descaling agent 5 in the form of a combination of citric, lactic and grape acid, and powdered soda 6. The individual components 2, 3, 4, 5, 6 of the cleaning tablet 1 are visualized by different symbols. Of course, other components of the
[0051] Cleaning tablet 1 is conceivable. In particular, a ceramic powder can also be provided in addition to or as an alternative to the glass powder 3.

[0054] Composition on:
[0055] 33% microcrystalline cellulose 2, 21% glass powder 3, 14%
[0056] Cleaning agent 4, 13% descaling agent 5 and 19% soda 6.
[0057] By means of such a composition, for example, an optimal
