Definitions

• the invention relates to a sanitary agent for cleaning, disinfecting and/or perfuming a sanitary appliance.
• the present invention relates to a sanitary agent which can adhere to an internal wall of a water-closet bowl or a urinal, remaining attached for a high number of water flushes up to its final consumption.
• Sanitary appliances for example hygienic toilet bowls or urinals fixed to a wall, have to be subjected to repeated cleaning and disinfecting operations in order to be able to maintain adequate hygienic sanitary conditions.
• the prior art comprises hanging sanitary agents by means of hooking device positioned in the water closet container, where one exists; the emission of the sanitary agent occurs at each discharge flush operation into the bowl.
• sanitary agents which are fixed to the perimeter edge of the toilet bowl by means of a support; these sanitary agents are normally inserted in particular devices, like cages, provided with the support means, such as for example a plastic bracket, and which also include slits and/or holes such as to enable a portion of the sanitary agent to exit at each flush of the water.
• the above-described sanitary agents when struck by the water which irrigates the toilet bowl, enriches the water with the substances contained in the agents, thus providing the elements required for deterging, descaling, deodorising and/or disinfecting the bowl.
• these devices are not very practical and hygienic; during manual cleaning of the edge of the toilet bowl or during the cleaning of the inside of the bowl by use of the toilet brush, the support means fixed to the edge of the bowl can be accidentally shifted and it is therefore necessary to reposition it. Further, on substitution of the sanitary agent, due to its consumption, it is necessary to act manually with ensuing operative and hygienic difficulties for 5 the user, as the devices are often positioned in poorly-accessible places, in any case not ideal from the hygienic point of view.
• the prior art comprises certain solutions to the above-cited problem, in which sanitary agents, in particular solid or semi-solid soaps can adhere stably to the internal wall of a WC bowl or a urinal in order to be subjected to regular water flushes.
• European patent EP 1 086 199 in the name of Buck-Chemie GmbH 0 describes a sanitary agent which can be applied directly on the surface of the sanitary appliance, the sanitary agent having a viscosity of at least 15,000 mPas and comprising an adhesion promoter such as poly oxy alcohol alkane, cellulose, etc.
• an adhesion promoter such as poly oxy alcohol alkane, cellulose, etc.
• the sanitary agent deforms, causing the components constituting it to drip downwards in an undesirable way.
• a further disadvantage is given by the fact that in order to be applied adequately to the part of the sanitary appliance, the sanitary agent described in the patent application obligatorily requires the use of a batching system normally constituted by rigid plastic material, with the consequence of an undesired and significant use of plastic material.
• EP application 2 141 221 in the name of Manitoba described a detergent pastille having a substantially flat adhesive surface for anchoring to a wall of the WC bowl and a shell-shaped surface such as to be subjected to the action of the flush water.
• a problem of the products using an adhesive part is that the adhesive part does not completely dissolve following the action of the flush water and therefore, once the detergent part of the pastille has been consumed, a manual intervention is required to remove the residue of the detergent pastille that has remained adhering to the part of the WC bowl.
• the aim of the present invention is to provide a sanitary agent for treatment of a sanitary appliance which constitutes an alternative to the solutions provided by the prior-art documents as cited above.
• the aim of the present invention is to provide a sanitary agent for treatment of a sanitary appliance, the sanitary agent comprising at least an adhesive component and at least a component that is useful for the treatment, the adhesive component being capable of enabling the sanitary agent to remain in adherence for a large number of water flushes to a sanitary appliance of any shape and, at the same time, once the component of the sanitary agent used for the treatment is consumed, to be easily dissolved in the water of further flushes.
• the present invention relates to a sanitary agent to be used for deterging, disinfecting and/or perfuming a sanitary appliance.
• a sanitary agent for treating a sanitary appliance comprising an active body, solid or semi-solid, including a treatment compound having at least an active element for treatment of the sanitary appliance and at least a surfactant, characterised in that it comprises an adhesive layer positioned on a portion of the external surface of the active body, in which the adhesive layer comprises at least an adhesive element deriving from colophony resin, destined to realise adhesion of the active body to the wall of the sanitary appliance, is capable of enabling the adhesion to last for a high number of water flushes, the sanitary agent dissolving substantially completely at the end of the operating cycle thereof and being of a shape such as to be able to adhere to sanitary appliances of any shape.
• the present invention has the advantage of providing a sanitary agent which comprises an adhesive layer and a treatment compound, in which the treatment compound can be any of the traditionally known treatment compositions.
• sanitary appliance is understood to mean a water-closet toilet bowl, a urinal bowl, a urinal or any other like apparatus which is usually subjected to water flushes in order to maintain cleanliness and hygiene thereof.
• treatment of a sanitary appliance is understood to mean cleaning, hygienising, disinfecting, perfuming and removing limescale, and other like operations applicable to the sanitary appliance.
• active element for the treatment is understood to means an element dedicated to cleaning, deterging, foaming, perfuming, deodorising, disinfecting, water-colouring, polishing, or any other element which is soluble in water and useful for the treatment to which the sanitary appliance is to be subjected.
• si-solid body is intended to mean a body having a pasty consistency, or having a consistency which is such as to be slightly modifiable in shape by manual pressure, but such as to maintain over time the given shape, even following the action of weak external forces, such as a water flush or discharge.
• the shape of the sanitary agent can be appropriately modelled on the basis of the shape of the wall in order to guarantee good adhesion. This shape can be maintained over time, except for the reduction in mass due to its dissolving by action of the flush water.
