Definitions

  • This invention is concerned with improvements in and relating to lavatory cleansing devices.
  • the invention is concerned with lavatory cleansing devices for immersion in the water cistern of a lavatory or urinal whereby, upon flushing, a dose of a treatment liquid, obtained by dissolving material from a solid block of material within a chamber of the device, is delivered to water in the cistern.
  • the present invention provides a lavatory device for immersion in the cistern of a lavatory or urinal comprising a chamber for containing water-soluble or water-dispersible treatment material, and syphon means in connection with the interior of the chamber and having an inlet spaced above the floor of the chamber and an outlet exterior of the chamber and below the level of the inlet and preferably below the level of the floor of the chamber.
  • the chamber for containing the treatment material may be open topped, whereby the device as a whole is refillable; i.e. a new portion or dose of treatment material may be introduced to replace exhausted treatment: material.
  • the chamber may have a generally closed top and, in this case, the upper part of the chamber should be provided with one or more vents to allow air to freely enter or leave the chamber.
  • a device in accordance with the invention is wholly or partially immersed in the cistern of a lavatory, preferably so that the upper part of the chamber is substantially at the same level as the uppermost water level in the cistern. Water thus enters the chamber through the syphon and, after flushing of the cistern, leaves the device through the syphon. It is most desirable that so-called "end dosing" can be achieved by operation of the device; that is the treatment material contained in is emptied preferably at the final discharge of the contents of the cistern. This ensures that the water finally introduced into the lavatory bowl; and which will remain there after flushing, will contain a higher concentration of treatment material. This is especially the case where the treatment material comprises a bleach, fragrance or disinfectant, so that the benefits of these remain in the bowl.
  • the total water capacity of the device i.e. the amount of water which will flow into the device when it is appropriately immersed in the cistern empty of any treatment material
  • the treatment material when present in wholly unconsumed form, suitably forms from 25 to 75% of the total, preferably from 30 to 50% thereof.
  • the total volume of liquid dosed in any one flushing is suitably 30 to 95%, preferably 50 to 90%, especially preferably 70 to 80%, of the total volume of liquid in the device. That is, by virtue of the supply entrance being located above the floor of the chamber, some water containing dissolved treatment material remains in the chamber.
  • the diameter of the syphon aperture is suitably 1 to 10, preferably 4 to 6 mm.
  • the diameter may, of course, vary depending on the nature of the cistern in which the device is to be employed and on the location of the device within that cistern.
  • the total capacity of the device may suitably be increased (generally pro rata) if it is to be used with a cistern of appreciably greater water capacity, and vice versa.
  • the treatment material to be used in the device of the invention is conveniently a solid block and, for convenience, in the following description reference will be made to solid blocks.
  • other forms of treatment material may be employed such as pastes or gels or particulate forms, such as granules, which latter are more conveniently contained in perforate flexible container (e.g. in a so-called "tea bag”) or in water-soluble pouches.
  • Figure 1 is a side elevation of one embodiment of lavatory cleansing device in accordance with the invention.
  • FIG. 2 is a vertical section through another embodiment of lavatory cleansing device in accordance with the invention.
  • Figure 3 is a plan view of the device shown in Figure 2.
  • the lavatory cleansing device shown in Figure 1 of the drawings comprises an open topped chamber 1, for containing a block of solid water-soluble or water-dispersable treatment material, the chamber having a lower extension 2 in connection with the inlet end 4 of a syphon tube 3 whose outlet 5 is disposed exterior to and and at a level below the floor of chamber 1.
  • Chamber 1 is further provided with water level indicating means (in the upper portion thereof) .
  • a block of solid treatment material is firstly inserted into chamber 1 and the whole device is then immersed in a cistern, when full, so that the water level indicating -means in chamber 1 is approximately level with the water level in the cistern. Under these conditions, of course, water will flow into chamber 1 through syphon 3 to fill the whole device to about the water level mark. Water in contact with the solid block of treatment material will partially dissolve it so as to form a solution of the treatment material within the device.
  • the water level in the cistern Upon flushing of the cistern, the water level in the cistern will, of course, descend, below the level of the floor of chamber l so that the solution in the device, or a part of it, will be syphoned off from the device by the operation of syphon 3.
  • the cistern refills the device itself will be refilled by water entering through syphon 3.
  • Devices in accordance with the invention are conveniently manufactured, by appropriate moulding techniques, from plastics materials such as polyethylene, polypropylene, PVC, etc.
  • the chamber 1 of the device shown in the drawing is open-topped so that blocks of cleaning or treatment material may be inserted into the device as and when a block in the device has become exhausted.
  • the treatment material to be inserted into the devices of the invention serves to introduce into the flush water in the cistern desired ingredients such as surfactants, colorants, fragrances, disinfectants, iodophors, chlorine-release agents or limescale removal or inhibition agents, and it will be formulated of appropriate materials, which may be water-soluble or water-dispersible, for providing such active ingredients
  • desired ingredients such as surfactants, colorants, fragrances, disinfectants, iodophors, chlorine-release agents or limescale removal or inhibition agents, and it will be formulated of appropriate materials, which may be water-soluble or water-dispersible, for providing such active ingredients
  • the treatment material m the device suitably has a weight from 5 to 150 gms, preferably 10 to 100 grms.
  • the unit dose e.g. block
  • the unit dose would have had to be relatively water-soluble as compared with, for example, a so-called “naked” or uncontainerised lavatory cleansing block of the sort which is simply placed per se, without any container, in the cistern of a lavatory or urinal.
  • the treatment material used in accordance with the invention will frequently comprise a surfactant component and a solubility control component, optionally together with any of a variety of other components such as fillers, colorants, fragrances, disinfectants, halogen-release agents and the like.
  • a surfactant component and a solubility control component
  • any of a variety of other components such as fillers, colorants, fragrances, disinfectants, halogen-release agents and the like.
  • the treatment material will be similar to the so-called naked blocks as discussed above.
  • the treatment material in a cleansing device of the invention will give a total life from 10 to 100 days, preferably 20 to 40 days, (at an average rate of 17 flushes per day) .
  • a formulation which, when formulated as a naked lavatory cleansing block having a weight of about 50 gms, gives a life of 40 to 60 days (measured under the above conditions) will give a formulation, when used as treatment material in accordance with the present invention, having the preferred in-use life. It is, accordingly, a matter of simple trial to decide whether any particular formulation will, or will not, be suitable for use in accordance with the present invention.
  • the treatment material when in block form, be formed by the steps of forming a mixture of the appropriate ingredients, extruding this into a rod and then cutting the rod into suitable lengths.
  • Other forms of treatment material may be made by appropriate methods, e.g. by tabletting the ingredients, forming a melt of the ingredients and moulding the melt, or by granulating the ingredients and then placing them in a suitable container.
  • solubility control agents may be employed including hydrophobes, difficultly soluble materials including difficultly soluble (low-ethoxylated) non-ionic surfactants, fatty acid alkanolamides, and rheological control agents such as gums.
  • many fragrances or perfumes are, in themselves, essentially hydrophobic and may serve as a part, or the whole of, the solubility control component.
  • the formulations were tested, as blocks having a weight of 50 grams, firstly, in a device of the invention and, secondly, as free standing blocks, at an average rate of 17 flushes per day in cisterns of 9 litres capacity. In the examples all percentages are by weight unless otherwise stated.
