Definitions

  • the present invention relates to lavatory blocks.
  • Lavatory blocks are known in the art and are typically configured to provide an automatic and sustained release of active ingredients to the lavatory environment. For example, they may be suspended in a container under the rim of a lavatory bowl or urinal such that, during a flushing cycle, water from the cistern flows over the block thereby dissolving a portion of the block and releasing active ingredients of the block into the lavatory bowl.
  • lavatory blocks contain a number of active ingredients in order to provide multiple lavatory care benefits such as cleansing, disinfection and fragrancing.
  • Formulating and processing blocks with multiple active ingredients can lead to problems due to the physical and/or chemical incompatibility of such ingredients. For example, it has become commonplace for lavatory blocks to contain a halogen release agent or other bleaching agent. Such materials are powerful chemically reactive species, which are difficult to combine with other oxidation sensitive components (such as perfumes), particularly since blocks are commonly made by extrusion which subjects the ingredients to elevated temperatures and pressures.
  • WO00/23558 describes how it is possible to provide a viable two-part lavatory cleansing block containing bleach and bleach-incompatible substances by extruding two compositions, only one of the compositions containing the bleach, and the other composition containing a component which is incompatible with the bleach, and ensuring that the two compositions do not have a common hydrophobe component. This is said to prevent the migration of the bleach sensitive component.
  • the block parts are co-extruded side-by-side.
  • a problem with such co-extrusion is that it places constraints on the formulation and the physical properties of the constituent block parts. For example, it is difficult to co-extrude parts of significantly different rheologies.
  • WO 99/38950 describes a lavatory cleansing block having an inner region and an outer region which both comprise a different fragrance.
  • the blocks are formed by co-extrusion.
  • lavatory blocks continue to produce lavatory care benefits (such as fragrancing) throughout the useful life of the block, which is typically around 3 to 4 weeks under normal domestic use conditions.
  • lavatory care benefits such as fragrancing
  • a problem with the incorporation of high levels of perfume into blocks formed by an extrusion process is that such incorporation may produce an overplasticised or sticky formulation consistency that is difficult to extrude.
  • perfume materials are normally hydrophobic and high levels may tend to ooze out from the block during manufacture and/or storage.
  • US 5,759,974 describes a WC stick with a relatively high fragrance content in a cast core. This is said to have the advantage of the possibility of incorporating very large quantities of perfume in the core.
  • the stick is manufactured by extruding a hollow shell, cutting the shell to its final length, and placing on a support in such a way that the moulding is closed underneath. The shells are then filled with the molten core material containing the perfume by means of a casting trolley.
  • a problem with this manufacturing method is that it is difficult to scale up and/or operate as a continuous process.
  • EP-A-1 418 225 discloses toilet cleaning and odorising agents comprising a gel phase and another phase, wherein the gel phase comprises a gel former, solvent and perfume.
  • WO03/04262 describes how the fragrance life of an in-the-bowl (ITB) toilet article may be extended by placing the perfume in the second chamber of a dual chamber housing so that the perfume is not in the path of the flushing toilet water.
  • the first chamber has an inlet and an outlet opening for water flow and typically contains a cleaning, disinfectant or anti-limescale composition in solid block form which fits into the chamber.
  • a problem with this proposal is that the dual chamber housing is an expensive configuration to manufacture. Also, since the perfume is placed within a gel system which is deposited in the second chamber of the housing, this means that the entire housing will need replacing by the consumer once the perfume is exhausted.
  • the underlying objective of the present invention is to resolve one or more of the problems outlined above.
  • the present invention provides a lavatory cleansing and freshening block, comprising a solid phase and a gel phase, in which the gel phase contains from 2% to 90% by weight perfume (based on the total weight of the gel phase) and is positioned on the surface of the solid phase, characterised in that the gel phase is formed from a polyamide resin.
  • the gel phase releases perfume during as well as between the flushes
  • the solid phase of the block according to the invention has a recess moulded on an outer surface in which the gel phase is positioned.
  • the solid phase of the block according to the invention is preferably formed by a process which includes extrusion.
  • a preferred process used to form the solid phase of the block is an extrusion process in which a mixture of the constituent ingredients of the solid phase is extruded into a continuous bar of solid phase which is subsequently cut into pieces of the desired size.
  • the solid phase may be in the form of a single, homogeneous composition, or alternatively may be in the form of one or more layers.
  • a multi-layered solid phase may suitably be produced by extrusion of the layers as complementary shapes which are brought together, or preferably by co-extrusion of the two layers side-by-side into a continuous bar as above.
  • the provision of a multi-layered solid phase is advantageous because it enables incompatible components such as bleach and dye, or bleach and bleach activator, to be segregated by placing them in different layers, thereby enhancing stability and performance of the block.
  • the solid phase of the block preferably has a recess moulded on an outer surface thereof, more preferably a longitudinal surface.
  • the recess extends along the entire length or width of the longitudinal surface of the solid phase of the block as a strip or groove.
  • the recess may be moulded on an outer longitudinal surface of the solid phase of the block by stamping, or preferably by extruding the constituent ingredients of the solid phase through a specially shaped extruder head so that the recess is formed in an outer longitudinal surface of the solid phase as it is extruded.
  • stamping or preferably by extruding the constituent ingredients of the solid phase through a specially shaped extruder head so that the recess is formed in an outer longitudinal surface of the solid phase as it is extruded.
  • the gel phase is positioned in the recess of the solid phase. Preferably it is put into position by injection into the recess. In a more preferred process, the constituent ingredients of the gel phase are heated, mixed and dosed through a nozzle into the recess of the solid phase.
  • the constituent ingredients of the solid phase are extruded through a specially shaped extruder head to form a recess as described above, and the extrudate so formed is mounted to travel upon a belt conveyor which is arranged so that the gel phase may be injected continuously into the recess of the solid phase as it travels along the belt conveyor, for example by dosing the gel phase into the recess through a nozzle as described above. Cooling and cutting of the gel-filled extrudate so formed may then take place to produce the final lavatory block according to the invention. Again this enables continuous operation of the block manufacturing process.
  • Fig 1 depicts an extruded block having a recess moulded along the entire length of a longitudinal surface of the solid phase 1, which is filled with the gel phase 2.
  • Fig. 2 depicts an extruded block having a recess moulded along the entire width of a longitudinal surface of the solid phase 1, which is filled with the gel phase 2.

  • the total amount of such materials, when present, will generally range from 5 to 50wt%, more preferably from 5 to 30wt% (by total weight of hygiene agent based on the total weight of the solid phase).
  • Preferred hygiene agents for use in the block according to the invention are bleaching agents, optionally in combination with one or more bleach activators.
