Definitions

  • the invention concerns a dispenser of active substances for WC bowls, of the type which comprises a container for the active substance and means for hooking the container to the rim of the bowl, in such a way as to maintain the container suspended in a position which is subjected to the action of the flush water.
  • dispensers for WC comprises a rigid cage-like container which contains a solid active substance in the form of a compacted block - usually referred to as a "rim-block".
  • the active substance is destined to dissolves on contact with the flush water, thus forming a liquid mixture which crosses the mesh of the cage and spreads over the inside walls of the WC bowl, there performing a perfuming, detergent, disinfectant action, or other types of action, according to the active substance being used.
  • the cage of the active substance and the means for fastening it to the WC bowl are typically made of plastic, through an injection moulding process.
  • the dispensers comprise a hooking means for suspending the dispenser from the rim of the bowl and a solid block comprising an active substance, in a position which is subject to the flush water, having a through-opening and a support element which supports the solid block by means of a cross-piece placed through the through-opening of the solid block.
  • An aim of the present invention is to realise a dispenser for a WC bowl which though requiring a very limited quantity of plastic obviates the above-mentioned drawback, and the solid block is consumed homogeneously and at a correct rate up until it is completely washed away.
  • a further aim of the invention is to achieve the above-mentioned aim within the ambit of a simple, rational and relatively inexpensive solution.
  • the dispenser comprises suspension means 10 which at their upper end exhibit a hook means 11 for suspending the dispenser from the rim 51 of the WC bowl 50.
  • the hook 11 can exhibit a shape which is traditional for dispensers, for example it can be made of elastically flexible material (typically plastic) which hooks onto the rim 51 of the bowl 50 and at the same time, as a reaction against the original deformation imposed upon it by the act of hooking, grips the rim 51 in such a way as to remain joined to the rim with sufficient force to resist any possible stresses tending to detach it, to which it is subjected during normal use of the bowl 50.
  • elastically flexible material typically plastic
  • a support element 20 which is situated at the other (lower) end of the suspension means 10 supports a solid block 30 comprising at least one active substance, in a position which is subjected to the action of the flush water.
  • the solid block 30 is formed from a substance which regularly and quite slowly dissolves when in contact with water, thereby forming a liquid mixture which performs an action that depends on the formulation of the active substance it contains.
  • the action can be detergent, disinfectant, enzymatic, anti-scale, whitening, deodorant, or a synergistic combination of two or more of the foregoing, and it can achieve its effect on the inside walls of the WC, on the water in the siphon, on the walls of the WC below the siphon water level, or in the discharge pipes.
  • the support element 20 and the solid block 30 are arranged in the WC bowl 50, against the inside surface 52 of the bowl 50, below the upper rim 51 of the bowl 50, and exposed to the action of flush-water flow.
  • flush water exits along the rim 51, flowing from holes 53 which are arranged on the lower part, or exits from a rear central outlet in the bowl 50 and is made to flow in a direction which is tangential to the inside surface 52, below the rim 51.
  • the solid block 30 exhibits a through-opening 31 afforded through its body, passing from a lateral surface 33 to the opposite surface 34.
  • the through-opening 31 has the form of a circular channel pass more or less through the centre of the block 30.
  • the block 30 can be formed by a single body, or by two or more bodies 30' which are arranged pack-fashion along the direction of the axis of the opening, as shown in figures 3 and 3A , or else are formed by a series of concentric bodies.
  • the support element 20 is connected to the suspension means 10, and comprises a cross-member 25, placed through the through-opening 31 of the solid block, and destined to support the solid block 30.
  • the support element 20 comprises two arms 22, 24, connected to the two ends of the cross-member 25, which exhibit, at the connection thereof with the cross-member 25, respective flat portions 22a, 24a adjacent to the surfaces 33 and respectively 34 of the solid block 30, having an extension which is such as to completely cover the mouths which the opening 31 forms on the surfaces 33, 34.
  • the support element 20 defines a closed ring shape able to pass from side to side through the opening 31 of the solid block.
  • the support element 20 comprises a shaped portion 21 having a U-shape, in particular downwardly-facing, and a cross-member 25, which is arranged traversing the through-opening 31 of the solid block 30, ends of which cross-member 25 are connected to lower ends of the U-shaped portion 21.
  • the U-shaped portion 21 and the cross-member 25 define the closed ring.
  • the shaped portion 21 comprises two straight elongate arms 22 and 24, which are substantially parallel and face downwardly, upper ends of which are solidly attached (in a single body) to the ends of the transversal arm 23, and the lower ends of which define the flat portions 22a, 24a adjacent to the surfaces 33 and 34, and the ends of the cross-member 25 are connected thereto.
  • the cross-member 25 exhibits at least an end that is removably connected to an end of the U-shaped portion, with a disconnectable connection.
  • the cross-member 25 exhibits a tapered end 26 shaped like a small spearhead which can be inserted through a hole 27, which is afforded in the lower end of the third arm 24, in such a way as to snap-fit thereto.
  • the other end of the cross-member 25 is solidly attached to the lower end of the first arm 22.
  • the lower end of the arm 22 defines the flat portion 22a while the lower end of the arm 24 defines the flat portion 24a; these two flat portions adhere to the surfaces 33, 34 of the solid block 30 and are able to effectively cover the two ends of the through-opening 31 from the passage of water.
  • the cross-member 25 exhibits external longitudinal ribbing 25' which renders the structure rigid.
  • the suspension means 10 comprise a stem 15 which extends from the hook 11 and joins, with its lower end, the downwardly-facing U-shaped portion 21.
  • the shaped portion 21 will project laterally relative to the stem 15 in such a way as to fit below the lower wall of the upper rim 51 and against the inside surface 52.
  • the arm 23 and the hook 11 grip the rim 51 of the bowl over a very wide angle (at least 270° in figure 3 ), thus making the connection of the dispenser to the rim 51 stable.
  • the solid block 30 has the shape of a cylindrical slab, with a through-opening 31 arranged along the longitudinal axis of the cylinder.
  • the flat protion 24a of the arm 24 is distanced from the end 26 of the cross-member 25, bending the arm 24, which by its own nature is elastically flexible.
  • the cross-member 25 is then inserted through the hole 31 in the block 30, and the flat portion 24a is connected to the free end of the cross-member 25, thus securing the end 26 within the hole 27.
  • the block 30 is suspended from the support element 20 and constrained to it by the closed ring which is formed by the three arms 22, 23, 24 and by the cross-member 25.
  • the block 30 remains suspended in a position in which it is subjected to the flush water flow and performs its action as if it were inserted within a traditional cage-like dispenser.
  • the second embodiment differs from the previous embodiment solely due to the different shape of the shaped portion 21.
  • the second arm which is horizontal and is joined transversely to the stem 15 (indicated by reference numeral 23'), is shorter and is no longer joined to the third arm 24.
  • the arm 24 is defined by the flat portion 24a having a disc shape, placed through the end of the cross-member 25, the external diameter of which is greater than the diameter of the opening 31, with a disconnectable connection.
  • the second arm 23' projects laterally with respect to the stem 15 in such a way as to come into contact with the lower surface of the lower wall of the rim 51 of the bowl, in order to render the connection of the dispenser to the rim 51 more stable.
  • the dispenser of the invention requires a much smaller quantity of materials, in particular of plastic, for its production, thus causing less environmental impact and costing less for materials, especially since there is no outer cage structure.
  • the dispenser of the invention is cheaper to produce, since the process for producing the suspension means 10 is rather simple and economical, enabling the high costs for injection-moulding the plastic to be reduced, and does not require sizeable investments in machines and moulds. Fitting the block 30 to the suspension means 10 is also simple and convenient to perform both manually or using machine assembly.
  • part of the flow of WC flush water also flows internally of the opening 31, and causes a relatively rapid widening of the opening 31, such that after a relatively low number of flushes the opening 31 reaches the perimeter of the block 30 and the block 30 detaches from the cross-member, or separates into two or more parts and in any case crumbles and is carried away by the flush water.
  • the working life of the block in these cases is very brief and unacceptable.
  • the dispenser in addition to the solid block 30 comprising at least one active substance in a position which is subjected to the action of the flush water, the dispenser comprises a diffuser element 40 for the airborne diffusion of substances, the diffuser element 40 being fixed to the suspension means 10, and diffusing at least one substance into the air, for example a perfuming or a deodorant substance, independently of the action of the WC flush water, in particular diffusing continuously and extensively over time.
  • the diffuser element 40 comprises a support wall 41 which is provided with at least one through-hole 42.
  • the suspension means 10 comprise at least one projecting body 43 which snap-fits to the support wall 41 via the through-hole 42.
  • the diffuser element 40 is provided with only one hole 42 in a central position and the body 43 is located on the first arm 22.
  • the diffuser element 40 shown here is of the type which comprises a forward shell 44 which is joined to the support wall 41 and contains a plurality of small bodies 46 which are soaked in a volatile substance, or other type of carrier material, such as gel. Through a series of slits 45 afforded in the shell 44, the volatile substance released by the bodies 46 diffuses into the surrounding environment.
  • the diffuser element 40 exhibits an elliptically elongate casing, with two holes 42 associated to two projecting bodies 43.
  • the diffuser means are of the type which enclose a (more or less dense) liquid substance contained in a tray formed by the profiled wall 41, allowing the perfuming/deodorant volatile substance given off by the liquid to pass through.
