Definitions

  • the present invention relates to a sanitizing device, particularly for sanitary fixtures and the like. More specifically, the invention relates to a sanitizing device that is adapted to release a sanitizing product following the passage of water in contact with it or through it.
  • sanitizing sanitary fixtures devices comprise a form of cage inside which a sanitizing product in tablet form is arranged.
  • the device is clipped to the sanitary fixture so as to remain in contact with the internal wall of the sanitary fixture, in particular in a position that corresponds to a point where water passes.
  • the water When the water is flushed, the water flows over or passes through the containment device of the tablet and the tablet releases sanitizing product in order to sanitize the sanitary fixture.
  • sanitization devices comprise containers of the cage type that are adapted to accommodate a product in tablet form which is constituted by a sanitizing product with gradual release.
  • a product in tablet form which is constituted by a sanitizing product with gradual release.
  • Such tablet is typically constituted by a solid material, accommodated in the cage, which dissolves upon the passage of water in contact with it.
  • the tablets have an unpleasant appearance, being opaque, and their outward appearance worsens as they are consumed.
  • the tablets are made using inert substances such as sodium carbonate, sodium sulfate, sodium chloride, calcium carbonate etc, in order to confer a solid texture.
  • inert substances such as sodium carbonate, sodium sulfate, sodium chloride, calcium carbonate etc.
  • the purpose of such inert substances are not linked to the performance of the product; they are only needed for the latter to have a solid texture.
  • some inert substances used tend to leak and therefore to leave undesired streaks on the inner surface of the sanitary fixture.
  • the inorganic substances in the tablet are very dense, with the drawback that in order to have a tablet of sufficient volume it is necessary to use a relatively high amount by weight of the product, with consequent high costs.
  • the application of a dose of gel on the wall is a much more complex operation than clipping to that sanitary fixture, since it entails exerting sufficient pressure, so as to make the dose of gel adhere to the wall, and a certain degree of dexterity in manipulating the device for applying the gel, whether it is in the form of a syringe (single dose or multidose) or in the form of a blister.
  • liquid tablets are known in which the product is therefore aqueous and free from inert substances.
  • Such tablets contain liquids that are also viscous but, however, they exhibit the drawback of needing to be handled like a liquid and therefore the container that holds them must be perfectly closed, and in order to obtain the desired sanitizing effect it is necessary to provide complex and expensive mechanisms to allow the gradual release of the liquid in use.
  • the aim of the present invention is to provide a sanitizing device for sanitary fixtures that overcomes the problems mentioned above with reference to the background art.
  • an object of the present invention is to provide a sanitizing device for sanitary fixtures that has all the advantages of the product in gel form without the corresponding drawbacks:
  • Another object of the present invention is to provide a sanitizing device for sanitary fixtures that maintains a pleasing appearance from the start to the end of its useful life following the gradual release in use of the sanitizing product contained in it.
  • Another object of the present invention is to provide a sanitizing device for sanitary fixtures that is highly reliable, easily and practically implemented and low cost.
  • a sanitizing device particularly for sanitary fixtures and the like, which comprises an open container body that is adapted to accommodate a sanitizing product, and a stem adapted to enable the clipping of said device to a sanitary fixture, characterized in that said container body accommodates a sanitizing product in gel form that is adapted to be released gradually by said container body as a consequence of the passage of water through said container body.
  • the sanitizing device generally designated by the reference numeral 1, comprises an open container body 2 that is adapted to define a form of cage for a sanitizing product, and a supporting stem 3, which is connected to the container body 2 and is adapted to be clipped to the edge of a sanitary fixture.
  • the supporting stem 3 can be provided at an angle with respect to the front surface of the container body 2, as shown in Figures 1-3 , or it can be aligned with the front surface of the container body 2.
  • the container body 2 is adapted to contain a sanitizing product in gel form 4.
  • sanitizing product is used to mean a sanitizing and/or scenting and/or cleaning product.
  • the container body 2 is provided with a plurality of slits 5 that are adapted to allow the release of the sanitizing product 4 in gel form, with the slits being advantageously arranged at the bottom surface of the container body 2, i.e. the surface that is adapted to be directed toward the wall of the sanitary fixture to which the sanitizing device is applied.
  • the slits are adapted to allow the product in gel form 4 to be struck directly by streams of water of the sanitary fixture and a direct discharge of the resulting solution with gradual release of the sanitizing product.
  • the slits 5 are arranged so as to leave a central region 6 of the body of the container full, with the slits 5 extending laterally thereto.
  • This particular configuration of the slits 5 allows the container body 2 to be filled without the product in gel form 4 immediately leaking through the slits 5, as will be described in detail below.
  • slits 5 that can also be continuous at the bottom of the container body 2, as long as they are provided in a certain dimension, as will be described in detail below.
  • slits 5 provided at the bottom of the container body 2 entails that the slits widen as they extend upward with respect to the direction of pouring of the product in gel form, i.e. at the edge regions of the container body: in this case the slits widen in a region 7, arranged for example perpendicular to the extension of the slits.
  • the size of the slits is extremely important to ensure that upon pouring the product in gel form, which is to be loaded into the container body 2, the product does not exit from the slits proper.
  • the slits 5 can have various shapes and dimensions, with a size limit of 2 mm width.
  • the size limit indicated previously of 2 mm for the width of the slits 5 ensures that, upon pouring the product in gel form 4 into the body 2 of the container, the product does not exit from the slits proper.
  • the gel is conveniently heated and poured at a certain temperature so that it is at the same time pourable and as viscous as possible.
  • the heating temperature to which the gel is heated must be such that at the moment of pouring the gel has a minimum viscosity of 500 mPa*s.
  • the actual filling temperature of the container body varies depending on the composition of the gel.
  • aqueous gels containing ethoxylated alcohols can require, for pouring, temperatures comprised between 75° and 80°C; for other gels temperatures lower than 60°C can suffice.
  • the important factor is that the gel is poured into the cage at a viscosity that is higher than 500 mPa*s or even more preferably even higher, between 800 and 1200 mPa*s.
  • the maximum width of 2 mm specified for the slits 5 makes it possible for the gel not to leak, as mentioned, upon the loading thereof into the container body 2, but at the same time it makes it possible to ensure the functionality, i.e. the passage of the water once the tablet in gel form is in use.
  • the method of pouring the gel into the container body 2 can also optionally entail, in addition to the heating of the gel indicated above, the contrivance of pouring the gel initially at a region where there are no slits or there are slits of very reduced thickness, so as to give time for the gel to constitute a certain mass such that it has greater difficulty in exiting from the slits once the mass of gel reaches the region where the slits are arranged.
  • the slits 5 are interrupted at a region defined on the bottom surface of the container body 2, it is advisable to pour the gel exactly in such region that is substantially free from slits 5, and therefore enable the mass of gel to then flow toward the region of the slits once the gel has created a mass that is such as to prevent the product in gel form from leaking through the slits 5 proper.
  • the portion 7 of slot will have a maximum size that can even exceed the 2 mm maximum indicated previously, as the portion 7 of slot is in a region of the container body 2 at its edges, a region that is reached by the mass of gel loaded in the container body 2 when such mass is no longer capable of flowing through the slits, even if the slits 5 have a size greater than 2 mm.
  • the viscosity of the gel during the filling must preferably be approximately 800-1200 mPa*s measured with a Haake viscometer VT550 MV2 at 5s-1.
  • This value is a indicative, and non-limiting, of the preferred viscosity of the gel.
  • the device according to the invention makes it possible to be loaded with a tablet made with a product in gel form, with the product in gel form being loaded in the container body of the sanitizing device without the product in gel form exiting from the slits for releasing the product during loading.
  • the characteristics of the gel make it possible to provide containment devices that are open or partially open, by taking advantage of the viscosity characteristics of the gel that enable its stable permanence inside a perforated container, even under the effect of streams of water.
  • the convenience remains unaltered of application to the sanitary fixture of a device of the cage type, which does not require particular dexterity or the need to come into contact with the internal wall of the sanitary fixture in order to directly apply a dose of gel.
  • the shape of the container body can be many according to the method of filling adopted and depending on the composition of the gel.
  • Figure 12 shows a fourth embodiment of the device according to the invention, in which the container body 2 is provided, at the upper surface thereof, which is adapted to be directed toward the opening of the sanitary fixture, with a plurality of walls 10 that are arranged in a labyrinth-like configuration and are mutually offset.
  • the container body has a boat-like shape and the walls 10 are vertical vanes.
  • Figure 13 shows a fifth embodiment of the device according to the invention, similar to the one in Figure 12 , with the walls 10 provided with holes 11 or with slits 12.
  • Figure 14 shows a sixth embodiment of the device according to the invention, similar to the ones in Figures 12 and 13 , in which the slits 5 defined on the container body 2 have a different orientation.
  • the materials used, as well as the contingent shapes and dimensions may be any according to the requirements and the state of the art.
