Definitions

  • the present invention relates to a detergent tablet for toilets with a detergent compartment with a detergent composition and a chlorine compartment with a chlorine component, a manufacturing method thereof and the use of such a detergent tablet as a toilet block, in particular for a urinal or for placement in a holding basket for a toilet bowl.
  • bleach-containing cleaners made up of biphasic tablet systems.
  • those biphasic systems are described in which bleaches and detergents are housed in different compartments so as not to fade the detergent range ingredients by direct contact with the bleach.
  • the bleach-containing areas with a water-soluble film or a slightly water-soluble material surrounded or enclosed, so that the bleach-sensitive substances, such as dyes or odors, are protected until their use before bleaching.
  • the bleach-sensitive substances are again in direct contact with the bleaching agent, so that bleaching or decomposition of the sensitive substances regularly takes place within a very short time during use.
  • a detergent tablet according to the invention for toilets with a detergent compartment with a detergent composition and a chlorine compartment with a chlorine component
  • the detergent composition and the chlorine component are at least partially separated by a barrier layer and at least one or a portion of a surface of the chlorine compartment is neither of the detergent composition prior to its intended use still covered by the barrier layer directly or indirectly.
  • Partially separated at least in part by a barrier layer means in the sense of the invention that the detergent compartment and the chlorine compartment are mechanically, in particular partially or completely, connected via a barrier layer which is largely stable under the respective conditions of use, so that the detergent tablet has defined proportions is present.
  • the barrier layer has the function that at least the major part of the cleaner composition is not in direct contact with the chlorine component during storage and secondly during use.
  • the advantage of this is that the components that are unstable to chlorine-containing reagents, such as most surfactants, dyes, fragrances, etc., are subject to degradation or fading upon storage and over an extended period of time during normal use or use to be protected.
  • the detergent tablet according to the invention may be a two-phase or multi-phase tablet, which is preferably present in the form of a detergent compartment with an integrated chlorine compartment or vice versa.
  • Two-phase or multi-phase means that at least two phases, solid-solid, solid-liquid, solid-gel-like are present. Each phase can form its own compartment, such as its own tablet or a separate part of a tablet. If a gel-like or liquid phase is present, then these are usually housed in a solid envelope, for example a plastic envelope or a coating, which, for example, only dissolves or becomes permeable to the respective component upon contact with water.
  • both the detergent compartment and the chlorine compartment are solid phases. This can also be achieved, for example, by applying a solution to a solid phase.
  • An example of such a separate embodiment is a so-called tab-in-tab variant, in which the chlorine component is made available in a, often smaller, chlorine compartment or a chlorine tablet and then integrated into a detergent compartment or detergent tablet.
  • an embodiment with reverse construction for.
  • a chlorine compartment with integrated detergent compartment possible. Since, however, the amount of chlorine component is usually less than the amount of the cleaner component, in most applications, the first Variant with a preferred from the purifier mass at least partially chlorine compartment preferred. Therefore, for the sake of simplicity, this variant is assumed below, this also including the reverse arrangement, unless otherwise stated.
  • the detergent composition according to the invention comprises at least one surfactant-containing detergent and preferably a surfactant mixture with surface-active effect to solve the deposits and contamination in toilets, especially in the toilet bowl or urinal, with each rinse and remove as much as possible.
  • the detergent tablet also called toilet stick or toilet stick
  • the detergent tablet is placed either in a holding basket in a toilet bowl or at the bottom of a urinal so that the detergent tablet is wetted by the rinse water during each rinsing process and thereby each time a part of the detergent and the chlorine component releases into the rinse water.
  • the cleaner composition is designed so that it dissolves in ordinary use only over a period of several days to several weeks.
  • the chlorine component may be any chlorine-containing reagent which has a cleaning action-promoting action with water, namely, primarily, a disinfecting and bleaching effect due to the release of chlorine-containing compounds. Released chlorinated compounds having such an effect may be, for example, free chlorine, but also hypochlorites.
  • the chlorine component is preferably so is selected to be substantially stable under normal ambient conditions, ie, in a dry or slightly humid environment, so that no or only small amounts of free chlorine or hypochlorite are released under these conditions.
  • the detergent tablet is used in a use according to the invention in the form of a toilet block or a toilet stick, in particular for a urinal or for use in a holding basket for a toilet bowl. It is expedient to mount the holding basket in a toilet bowl in such a way or hang on the edge that only from time to time during flushing with the rinse water is wetted, but not regularly in the wet state.
  • the barrier layer may be formed from a material and / or in a thickness such that it dissolves more slowly during the intended use, in particular in contact with water, than the detergent compartment and the chlorine compartment. This can be achieved be that the barrier layer is largely stable and decomposition of chlorine-unstable ingredients in the detergent compartment is largely avoided.
  • the smaller compartment usually the chlorine compartment
  • the barrier layer covers both the bottom area and the side areas.
  • the barrier layer may also go beyond the interfaces between the two compartments.
  • An example would be a tab-in-tab variant in which two tablets of different sizes are combined as compartments. For example, a smaller cylindrical tablet can be sunk in a likewise cylindrical depression of a larger tablet.
  • the barrier layer can be attached both to the bottom, the sides and in a part of the protruding from the recess top of the smaller tablet or the larger, surrounding the smaller tablet tablet to further complicate the direct contact between the chlorine component and the cleaner composition ,
  • the thickness of the barrier layer necessary to ensure the corresponding solution speeds can usually already be set in a suitable range.
  • the barrier layer whose solubility is inferior to the surrounding materials of the detergent compartment or of the chlorine compartment.
  • the cleaner composition of the detergent compartment and the chlorine component of the chlorine compartment tend to dissolve faster than the barrier layer, so that the tendency for separation of the two components from the barrier layer is much less than in conventional systems.
  • the advantage is that the two compartments remain separated for a longer time even in use.
  • a chlorine compartment integrated into a detergent compartment the chlorine component, in particular the not covered with a barrier layer part of the chlorine compartment, preferably coated with a complete or partial coating or a coating as an additional protective layer for storage, so that no direct contact between the chlorine component and the purifier mass is given.
  • the chlorine compartment be sealed in a slightly water-soluble protective cover before it is glued into the detergent compartment by means of a barrier layer adhesive.
  • the chlorine component is then indirectly covered by the barrier layer at least in the areas adjacent to the detergent compartment.
  • a protective layer usually fulfills a protective effect against the intended use, for example during storage or handling during production, but has no effect as a barrier layer.
  • the stability of the ingredients of the cleaner composition can be maintained over several years.
  • a protective layer can be, for example, a polymer film, in particular a polyvinyl alcohol film, or a coating of such a material.
  • the barrier layer is at least partially formed by an adhesive which holds the chlorine compartment in the detergent compartment or the detergent compartment in the chlorine compartment.
  • a barrier layer also used for connecting or gluing the two tablets means, such as an adhesive take over. This is introduced during the manufacturing process of the detergent tablet according to the invention, for example, in molten or other liquid form in a recess of a detergent and distributed by pressing a chlorine compartment in this depression in the spaces formed by the two tablets or in the open pores of the detergent.
  • Upon cooling or curing of the molten or liquid adhesive then forms a barrier layer in situ on the chlorine compartment at least at the direct contact points to the detergent compartment.
  • a separate complete enclosure of the chlorine compartment can be omitted, thereby reducing production costs.
  • Preferred materials employed for this barrier layer include, for example, high molecular weight polyethylene glycols, paraffins / waxes, stearate, silicates (e.g., waterglass), teflon, silicones, aluminas, or a mixture thereof.
  • the detergent tablet is characterized in that the detergent composition comprises one or more components, for example consisting of surfactant-containing cleaning agents, polymers, sulfates, carbonates, citrates, dyes, fragrances, fillers and tabletting aids.
  • the detergent composition comprises a combination of these components, optionally also in combination with other conventional ingredients for such detergent tablets such as preservatives.
  • An exemplary preferred detergent composition includes, for example, one or more detergents, one or more polymers, sodium sulfate, sodium carbonate, trisodium citrate, or a combination thereof.
  • the detergent tablet comprises one or more surfactant-containing cleaning agents.
  • Preferred examples of the surfactant-containing detergent are selected from salts of alkylbenzenesulfonic acid, fatty alcohol sulfate, fatty acid alkanolamide, fatty alcohol ethoxylate, ether sulfate, polyethylene glycol and ethoxylated alcohols, which may be used alone or in combination with each other.
  • the chlorine component comprises a granular matrix having at least one chlorine-containing reagent and at least one chlorine-stable surfactant.
  • a matrix of chlorine-stable surfactants and optionally further auxiliaries leads to an additional separation and has a positive effect on the pressing behavior and the tablet strength.
  • These chlorine-stable surfactants can also be used, for example, to form a barrier layer.
  • the matrix of the chlorine compartment in this case would itself act as such a barrier so that an extra barrier between the detergent compartment and the chlorine compartment could be omitted.
  • Examples of such chlorine-stable surfactants are especially amine oxides, etc.
  • the chlorine component may be mixed with detergent fillers, tableting aids or a mixture thereof.
  • the chlorine component comprises, for example, dichloroisocyanurate (eg the sodium salt) or trichloroisocyanuric acid or a mixture thereof.
  • dichloroisocyanurate eg the sodium salt
  • trichloroisocyanuric acid breaks down chlorine in an acidic environment, whereas in an alkaline environment, the acid is first neutralized before hypochlorite is formed.
  • trichloroisocyanuric acid When trichloroisocyanuric acid was used, several studies have shown that it has the advantage over dichloroisocyanurate of being less reactive. Especially with incorrect use of acidic cleaning agents, eg. As in the household, trichloroisocyanuric acid has the advantage that in the unwanted contact with the acidic medium (eg., An acidic toilet cleaner) significantly less toxic chlorine-containing gases or chlorine gas are released. This is probably due to the above different chemical behavior.
  • the acidic medium eg., An acidic toilet cleaner
  • a preferred embodiment of the detergent tablet comprises the chlorine component dichloroisocyanurate in less than about 50 wt .-%, and preferably between about 5 to about 35 wt .-%. Based on the total tablet, the dichloroisocyanurate is preferably below 25% by weight and more preferably at about 2-15% by weight.
  • Trichloroisocyanuric acid is comprised in at least about 20% by weight, but not more than about 80% by weight, and preferably at least about 40 to about 70% by weight in a preferred embodiment to achieve the cleaning-promoting effect. Based on the total tablet, the trichloroisocyanuric acid is preferably below 40 wt .-% and more preferably at about 5-25 wt .-%.
  • the detergent tablets can in principle be produced with each production process, wherein an extrusion process is preferred in which, after the separation of individual detergent compartments with the detergent composition, a single can be combined with the chlorine component, preferably in the form of a separately produced by extrusion chlorine compartment.
  • the cleaner composition and / or the chlorine component are produced from extruded kneading compounds and both components are at least partially separated in a detergent tablet by a barrier layer.
  • the barrier layer components may be sprayed onto either the detergent mass or the chlorine component or the respective compartment or both compartments may also be immersed in a barrier layer solution with the interfaces.
  • the barrier layer component may for example also be injected between the two compartments by means of a nozzle, for example while these are guided into one another.
  • the detergent compartment may be prepared in a kneader with subsequent extruder.
  • the ingredients of the cleaning animal are usually mixed in the kneader and then formed by means of an extruder into a strand.
  • mixing and extruding can also be done in one go.
  • the individual tablets for the detergent compartment can be cut from this strand.
  • the compression of the extruded detergent composition for the purpose of continuous production in a rotary tablet press or an extender press done.
  • the chlorine compartment may be introduced into a well in the detergent compartment by means of a barrier layer serving as an adhesive to substantially separate the detergent composition and the chlorine component.
  • a number of holes e.g. B. one or two or more holes are introduced during the extrusion in the extruded molded body into which then a number of chlorine compartments can be used.
  • a chlorine compartment is used per hole, and it is also conceivable to use several chlorine compartments in a hole, for example one above the other.
  • the adhesive can again serve as a barrier layer, if no separate barrier layer is to be formed.
  • two largely uniform tablets can be combined with one another via a barrier layer, so that a two-layered system is produced. The amount of the respective component can be adjusted via the thickness or the diameter of the tablets as needed.
  • the detergent tablet according to the invention may preferably be used individually or in a defined number in a welded film (for example polyvinyl alcohol film), a so-called Flowpack (a tubular bag in which the products are placed horizontally in the bag for packaging), so that it can be accurately and easily dosed.
  • a single packaging of each detergent tablet is particularly preferred, as this can prevent or at least reduce endangering of the users by chlorine-containing ingredients and a deterioration of the product quality during storage.
  • the detergent tablet according to the invention can be favorably used as a toilet block or as a toilet stick if the detergent composition and the chlorine component are at least partially separated in the detergent tablet over a period of at least two weeks and preferably about three to eight weeks.
  • This is advantageous because the effect of each compartment, that is, the cleaning function by the cleaning agent and the cleaning-supporting function of the chlorine component, combined over a long period of time and complement each other.
  • the other constituents of the cleaning composition that are often unstable with respect to chlorine-containing compounds, such as, for example, perfumes (eg perfume ingredients), dyes, and some surfactants, can thus be stably integrated into the detergent tablet over a relatively long period of time.
  • the detergent compartment may for example be designed so that it is usually slow in an aqueous environment, in particular in a continuous or interrupted superficial Rinse with water (depending on the irrigation system in the urinal or the toilet bowl), that is about several days or weeks, dissolves.
  • the chlorine component is housed in a corresponding compartment separated from the detergent compartment and may be correspondingly displaced in time or dissolved in water simultaneously with it.
