Definitions

  • the present invention relates to multi-coloured laundry products dispensed in deformable packaging.
  • Bottom dispensing packaging offers the consumer many advantages in terms of ease of dispensing. Viscous fluids may be stored in such packaging as higher viscosities reduce leakage from a bottom-oriented dispensing aperture or valve.
  • multi-coloured laundry liquids within certain types of packaging namely deformable bottom dispensing packaging, can present technical challenges. Multiple and distinct colours achieved chemically e.g. by phase-separation are adversely affected when deformable packaging is squeezed, as squeezing can lead to mixing of the phases. With viscous fluids, mixed phases can take some time to separate reducing the visual effect experienced by the consumer when using the product.
  • the object of the present invention is to provide a multi-coloured viscous laundry composition in a deformable bottom dispensing packaging, which can be squeezed freely without mixing different colours but without the need for formulation modification.
  • the invention provides a transparent fluid composition in packaging, the composition:
  • a deformable, bottom-dispensing packaging comprising:
  • a container comprising a front wall and opposing rear wall, (ii) each wall comprising an inner layer which is transparent such that its light transmittance is greater than 25% at wavelength of about 410-800 nm, (iii) and an outer layer which is opaque such that its light transmittance is less than 25% at wavelength of about 410-800 nm;
  • the fluid laundry composition can be coloured with deep, vivid and distinct colours to create a stunning effect whilst still enabling squeezing of the deformable bottle which does not adversely affect the colour effects.
  • the entire inner surface of the rear wall is coloured.
  • the inner surface of the rear outer wall is coloured with multiple colours.
  • the colours are preferably bright vivid colours, and are defined by the CIE L * C * H * colour space.
  • the L * C * H * colour space is in the form of a sphere.
  • the vertical L * axis represents Luminance or lightness: from 0 representing no lightness (absolute black) at the bottom, with 50 at the middle to 100 representing maximum lightness (i.e. absolute white) at the top.
  • H * or H° axis represents Hue and is a circular horizontal axis passing through the centre.
  • the units are in the form of degrees 0 , ranging from 0° (red) through 90° (yellow), 180° (green), 270° (blue) back to 0°.
  • the C * axis represents Chroma or "saturation": 0 at the centre of the circle is completely unsaturated (i.e. a neutral grey, black or white) through to 100 at the edge of the circle which is maximum Chroma or saturation.
  • C * is greater than 20.
  • the or each colour of the rear wall may be located in a region of the L * C * H * sphere, said region forming an equatorial shell which passes through and is asymmetrical about the centre and occupies less than a third of the volume of the sphere.
  • the inclusion in the composition of high levels of strong dyes/pigments to achieve vivid coloured compositions is therefore not required allowing for formulations which are suitable for sensitive skin.
  • the package may comprise one or more side walls with inner and outer layers as defined above.
  • the one or side walls may be coloured as for the rear wall.
  • the or each window is as small as possible so that the package can offer protection to any light-sensitive components.

  • the window(s) correspond positionally with all colours of the rear wall.
  • Mulitple windows may be arranged so that the elongate sections together positionally correspond with all the colours of the rear wall.
  • the colours may be in zones and the elongate sections positionally correspond by overlapping (when viewed from at least the front) with a portion of the zone.
  • Suitable materials for the transparent inner layer of the package include, but are not limited to: polypropylene (PP), polyethylene (PE), polycarbonate (PC), polyamides (PA) and/or polyethylene terephthalate (PETE), polyvinylchloride (PVC); and polystyrene (PS).
  • the container may formed by extrusion, moulding e.g. blow moulding from a preform or by thermoforming or by injection moulding.
  • the transparent layer of the package according to the invention preferably has a transmittance of more than 25%, more preferably more than 30%, more preferably more than 40%, more preferably more than 50% in the visible part of the spectrum (approx. 410-800 nm).

  • H * or H° axis represents Hue and is a circular horizontal axis passing through the centre.
  • the units are in the form of degrees 0 , ranging from 0° (red) through 90° (yellow), 180° (green), 270° (blue) back to 0°.
  • the C * axis represents Chroma or "saturation": 0 at the centre of the circle is completely unsaturated (i.e. a neutral grey, black or white) through to 100 at the edge of the circle which is maximum Chroma or saturation.
  • the or each colour of the rear wall can be located in the region forming a horizontal spherical segment which passes through and is asymmetical about the centre and occupies less than a third of the volume of the sphere.
  • Each window comprises elongate sections 13, each elongate section 13 corresponding positionally (when viewed from the front i.e. as in figure 1 ) with at least three colours on the inner surface of the outer rear wall. Together the windows 5a 5b correspond positionally with all the colours of the rear wall. Positional correspondence is achieved by overlapping with zones 7.

  • the windows may be defined by lines of perforations so that the unwanted material is removed to form the windows after application of the sleeve.
  • the package 1 is bottom-dispensing and accordingly comprises a dispensing device 9 located at the base of the container 2.
  • the dispensing device 9 shown comprises a pretreater 11 but this is optional.
  • the dispensing device 9 is enclosed by a dosing closure device 15 which itself comprises a supportive base of the package.
  • the bottle container 2 and dispensing device 9 are connected to each other by threaded or snap-fit connections.
  • top 29 of the bottle is shown flat but in other embodiments it may be curved as shown in dotted line 31 to discourage storage top-down.
  • the closure 15 includes an enlarged (with respect to at least the neck region of the bottle) flat, generally planar bottom surface 15. By providing an enlarged flat top surface 15, the surface allows the closure 13 to function as a supportive base 13 with the bottle 7 in an inverted position thereby allowing the composition to accumulate (under gravity) during storage at the dispensing device 9.
  • the closure 15 includes a reservoir portion 17 in which the pretreater 12 is enclosed.
  • the closure is taped outwardly toward the surface 15 to provide a stable base.

  • the valve 21 comprises a membrane extending across an orifice 25 in the dispensing part 9.
  • the membrane has an arcuate portion (not shown) directed toward the container 7.
  • the arcuate portion of the membrane is provided with a intersecting slits to define a plurality of generally triangular leaves.
  • the triangular leaves bend toward the open end of the orifice 25 allowing product to pass through the orifice 25.
  • the dispensing pressure is released, the triangular leaves spring back to their original position and operate to block passage of product through the orifice 25.
  • the leaves of the valve are sufficiently resilient that they do not bend open unless the applied pressure exceeds the hydraulic static head pressure generated by a full of condiment. In use, the fluid is pressurised to flow past and partially collect on the pretreater part 12 ready for cleaning.
  • any of the fluid which remains on the pretreater part 12, can drip from the pretreater during storage and is collected in the reservoir portion 17 for use in the next wash. This reduces waste of product.
  • the container is rigid.
  • the present invention can be adapted for use with flexible packages such as bags, pouches and the like. Table 1. Exemplary Transparent Detergent Formulation
