Definitions

  • the present invention relates to a device cleaning and refreshing a bowl of W.C. It aims more particularly at a device enabling spill, following a jet or a storm of water coming of a container, a product containing one or more substances active on the walls of the bowl bathed by the flow water and ensure the maintenance of a fresh and scented, by the diffusion and evaporation of an agent volatile refreshment.
  • This device comprises a reservoir for product containing active substances, means of suspension to suspend the device on the edge of the W.C bowl, a diffuser tray arranged between the outlet tank and the rinsing water path as well as a liquid-permeable closure system which ensures the in communication between the reservoir and the porous mass.
  • this product is generally colored, viscous or gelling, it remains, in the absence of water rinsing, hanging on the walls of the bowl, which leads to unsightly traits or deposits.
  • the use of a diffuser tray provided with a plurality of grooves does not facilitate, because of the exchange surface limited only to the grooves, the diffusion and evaporation of the volatile agent ensuring the Refreshments.
  • Another device for cleaning and known refresh described by the European document EP 0 785 315, sought to solve the particular problem of the venting of the tank by the presence of a double annular orifice between the outlet orifice of the reservoir and the porous mass, one of these orifices allowing the flow of the fluid product, the other ensuring the passage of air to the tank.
  • WO 00 42261 Also known from WO 00 42261 is a device for the release of an agent in the rinse water, in particular in toilet bowls, this release by means of a distribution device complicated, consisting of two elements practically fit of plates, each of these plates including grooves which intersect in a perfectly orderly way.
  • the present invention therefore aims to overcome the disadvantages of the devices according to the prior art, proposing a device for cleaning and refreshing which is, on the one hand, devoid of porous mass, and, on the other on the other hand, of great simplicity of design and a very low cost, which guarantees evaporation optimum of the volatile coolant.
  • the cleaning and refreshing a bowl of W.C comprising a tank for active substances, connected to a receptacle, suspension means for suspending the receptacle at the rim of the W.C bowl, a means of diffusion disposed between the outlet of the reservoir and the path of the rinsing water and a means of closing which ensures the communication between the tank and the means of dissemination, is characterized in that the means of on the one hand, a single between the outlet of the reservoir and a network of conducted, this single passage being intended both for the flow of product to the outside of the tank and to the air flow of venting the tank, the pipe network being disposed on a substantially horizontal wall of the receptacle, and secondly, a tray positioned in a Receptacle housing below the pipe network and facing a defined free area the pipeline network, the platform being provided with a plurality of reliefs.
  • this one has a reservoir for active substances.
  • This tank 1 generally of plastic material, obtained in particular by traditional thermoforming techniques or extrusion, is intended to contain the product to be dispensed.
  • the term product any fluid conditioned in the liquid or gel state, comprising, for example in solution, one or more substances to ensure, inter alia, disinfection, and / or cleaning, descaling, during the deposition of said produced on the walls of the W.C, as a result of the training made by the stream of water coming from the hunt.
  • Tank 1 (shown in FIG. less an outlet orifice 2 having means for opening and closing. These means make it possible the tank filled with product, as long as the tank 1 is not properly positioned on a receptacle 4.
  • this is including a screw cap, fitted on the neck forming the outlet port 2 of the tank; this cap (which may not exist depending on the type of packaging) is removed by the user to expose an operculum or any other equivalent system performing a function of check valve.
  • this valve is released (in the case of a seal, the latter is forced by a party corner protruding from the receptacle) during the tank 1 on receptacle 4, the product may to flow and walk, especially by gravity, towards diffusion means 5 associated with the receptacle 4.
  • the receptacle 4 in particular made of plastic material, is performed as a result of molding operations. consistent substantially in the trough, it cooperates by casing or by clipping with the tank 1.
  • the receptacle 4 is delimited globally by its walls sides 6, 7, 8, 9 and its bottom wall 10.
  • the receptacle 4 further comprises and protruding vertically with respect to the bottom wall 10, on the one hand, a portion 11, in particular cylindrical, intended to cooperate with the level of the outlet 2 of the tank 1 and other on the other hand, a plurality of ribs 13 allowing both stiffen the receptacle 4 and support the tank 1.
  • the part 11 delimits a single passage between the outlet orifice 2 of the tank 1 and a network of pipes, this single passage allowing both adduction in product flow from the tank 1 to the means of dissemination 5 and the the free air of the tank 1.
  • Part 11 positioned substantially in the area median before 12 of the receptacle 4 (we can refer to Figures 3, 4, in which the median area before 12 actually corresponds to the area farthest from the edge of the bowl), has at one of its ends 11a, a crown with bevelled edges that delimit between them corners capable of uncapping the outlet orifice 2 of the tank 1 and hold the lid in a position in which he is not likely to close unexpectedly the outlet orifice 2 of the tank.
  • the other end 11b of the cylindrical part opens into at least one annular cavity 11c, which is come of manufacture during the development of the receptacle 4.
  • This annular cavity 11c travels laterally, and substantially in the same diameter, at least one channel 14 formed by the flanks of ribs 13.
  • channels 14a, 14b extend laterally around of the annular cavity 11c, each of these channels 14a, 14b opening at its first end in said cavity 11c, while the other end ends in at least one room 16a, 16b.
  • These rooms are also elaborated during of the manufacture of the receptacle and are for example of cylindrical profile.
  • the channels 14a, 14b comprise each a bottom wall 14c inclined.
  • the bottom walls extend from the cavity 11c to each of the chambers 16a, 16b so that the defined intersection areas respectively by the chambers 16a, 16b and the channels 14a, 14b and the cavity 11c, the channels 14a, 14b have different straight surfaces that are decreasing since the cavity 11c to each of the chambers 16a, 16b. Thanks to trapezoidal profiles of the channels 14a, 14b, the venting tank 2 by promoting expansion air bubbles within the channels 16a, 16b.
  • each of the rooms 16a, 16b is in the same plane already defined by the channels 14a, 14b and the cavity 11c, while their vertex lies in a plane raised with respect to the channels 14a, 14b, and to the cavity 11c.
  • the chambers 16a, 16b, the channels 14a, 14b, and the cavity 11c together define a network of pipes in the receptacle, this network lying by construction in a lower plane compared to the outlet orifice 2 of the tank 1 when the latter cooperates in the receptacle 4.
  • the 16a, 16b have, at their free end, of orifices 17a, 17b which ensure the communication of the network of pipes with the atmosphere.
  • the chambers 16a, 16b constitute two fulcrums 15a, 15b necessary to maintain the reservoir 1 in the receptacle 4, a third support point 15c being positioned substantially on the mediator of the segment joining the chambers 16a, 16b, in a back medial area (relative to the median area before whose relative position has been explained above).
