ABSTRACT:
The invention concerns a sanitary agent for cleaning and/or disinfecting and/or releasing a deodorant for sanitary objects such as toilet bowls. It is known to hang sanitary agents in the water tank by means of appropriate hanging devices, whereby from there the release of the sanitary agent takes place evenly with each flushing action in the toilet bowl. Sanitary agents are also known for use in toilet hang-in baskets, which are attached through a holder to the toilet bowl edge, whereby the sanitary agent is released with each flushing action.
A disadvantage with these known devices is its replacement by hand with a new sanitary agent, for example, in the form of a toilet cleaning block, in the existing uptake system when the sanitary agent has been used up. Among the users there exists a psychological block about putting a new one in the device after using up the sanitary agent, especially in the case of the toilet hang-in basket, whose refilling requires putting one's hand in the toilet bowl. The take-up devices that go there are only partly and with difficulty accessible on the unhygienic places, and replacing the agent is associated with a certain expenditure of time. Moreover, the conventional toilet hang-in basket causes problems due to the hanger-shaped holder if one wishes to clean the toilet bowl edge by hand where the holder is attached.
Another disadvantage with the toilet hang-in basket is that, during cleaning with the toilet bowl brush, it can, for example, be easily displaced and then must be put on the desired place again by using one's hands, which is unhygienic. Also disadvantageous about the hang-in basket is that in some cases it can be considered a toy by children and can be removed from the edge of the bowl. Usually a single toilet hang-in basket is used on a sanitary object so thatch the effect of the sanitary agent is locally limited and the amount is limited by the maximum filling capacity of the hang-in basket and/or the size of the sanitary agent to be used.
Such sanitary agents that are used in appropriate hanging devices are known in the form of solid blocks and recently also in gel form. Such gel-shaped sanitary agents can be filled according to need and not only when the entire sanitary agent is completely used up. Of course, with these gel-shaped sanitary agents, which, for instance, are described in DE 197 15 872, it is also necessary to refill them in the hanging device, which is considered by consumers to be unhygienic.
Moreover, sanitary agents are known and freely available on the market that are usually applied to the toilet bowl in liquid form from bottles from time to time-to then be flushed away immediately during the next flushing action. Accordingly a new application of the sanitary agent is necessary for each cleaning and/or disinfection action, which on the one hand is connected with a corresponding expenditure of time and on the other hand leads to a quick consumption of the sanitary agent with corresponding frequent cleaning, especially with daily cleaning. The cleanliness to be obtained with the liquid cleaners is also not lasting, and not everyone immediately takes a sanitary agent in the hand when the toilet gets dirty, whether in the private or public arena. In DE 195 25 604, which concerns a liquid, acidic cleaning agent for the removal of calcium, it is suggested that a thickener be mixed in with the acidic cleaning agent to increase the viscosity and thus improve the removal of calcium—especially on vertical surfaces. Of course, this publication teaches us that the viscosity of a liquid cleaning agent cannot be increased at one's desire because when it is, the removal of calcium build-ups and the necessary distribution of the cleaner cannot be attained anymore.
Difficulties with a hygienic and time-saving cleaning agent also occur with urinals. They are usually cleaned with a liquid cleaning agent, which is nonetheless immediately flushed away so that the cleaning flushing and the odor of freshness and cleanliness do not last. The urinals must therefore be cleaned continually.
The “hang-in basket solution,” which is felt to be unhygienic by consumers due to the necessary replacement of the agent and which nonetheless guarantees a longer lasting cleaning and release of deodorant, cannot be realized in urinals in most cases due to the shape of the urinal and the lack of a suitable hanging edge. To obtain a longer lasting cleaning of the urinal and release of a deodorant one is aided by the use of “toilet stones,” which are thrown in the toilet bowl or discharge water. They are, however, partly flushed away by the flush stream and also lead to undesired sprays. In some cases garbage such as cigarette butts are also thrown into the urinals so that cleaning personnel must sort out the “toilet stones” from the garbage in the urinal bowl when the “toilet stones” are not flushed away together with the trash.
Starting with this prior art, the problem that the invention seeks to solve is to make a sanitary agent available that obtains a long-lasting cleaning and/or deodorant-releasing and/or disinfecting effect and that can be applied in a simple and hygienic manner.
A problem of this sort is solved by a sanitary agent with the properties of claim

SUMMARY OF THE INVENTION
Amazingly, it was determined that it is possible to produce a sanitary agent that can be put directly on the surface of the sanitary object to be cleaned and that adheres there so that the known holders for the sanitary agents that are felt to be unhygienic can be abandoned; this was achieved by using an adhesion promoter, namely long or long-chained organic molecules with at least one hydrophilic residual together with water in the sanitary agent.
Through the interaction between the hydrophylic part of the adhesion-promoting molecule and water especially the surface of the agent becomes “sticky,” which makes an application directly onto the surface of the sanitary object possible. The application can take place with any suitable device such as a spray, tube, cartridge, spray nozzle, etc. The consumer only activates the applicator; contact with a possibly dirtied toilet hang-in basket is avoided.
The agent according to the invention can thus be applied and renewed in a hygienic way without touching the possibly dirtied facilities associated with the toilet bowl.
A considerable advantage of the agent according to the invention consists in the fact that it can be apportioned according to the desires of the consumer. If the consumer wants an intensive release of deodorant or if the toilet is used frequently, the consumer can use correspondingly larger amounts.
The agent according to the invention can also be applied in a simple way on different places of the sanitary object at the same time, for instance, to obtain a consistent cleaning effect both on the right and left side of a toilet bowl.
The agent according to the invention can also be applied in various compositions on various places on a sanitary object. This makes possible, for instance, that two incompatible components, for example, a halogen-releasing agent and an oxidation-sensitive fragrance, can be used by separating them locally for a common cleaning and/or deodorizing of the toilet.
The agent can be “sticky” either through a certain water content already in the formulation to be applied or the adhesion can be obtained by a light dampening of the surface—for example, by activating the flush water—and then applying the agent.
The adhesion obtained is so good on the sanitary object even with an application on a vertical surface that the agent does not become detached with the additional action of the streams of rinse water.
As a result of the adhesion promoter's hydrophilic part, the adhesion promoter detaches together with the residual sanitary agent little by little so that no undesired “sticky places” remain on the sanitary object, as is the case, for instance, with a simple “taping” of the sanitary agent with the double-sided adhesive tape.
