Definitions

  • the present invention concerns a viscous laundry product and packaging therefore.
  • An objective is to provide an improved pre-treatment device for the precise pre-treatment of laundry stains.
  • the present invention provides a packaged laundry product comprising a flowable laundry composition contained in a package, wherein:
  • the invention provides a method of treating a stain on a fabric using the device of the first aspect, the method comprising the steps of:
  • Steps (ii) and (iii) may be repeated at least once e.g. for larger stains, where repeated loading of the stain treatment device is needed.
  • the advantage of the above arrangement is that it offers great ease in a high viscosity composition vis-à-vis stained areas. Highly viscous liquids or gels are desirable for treating as they do not spread out so much after application and so can be restricted to the stain area.
  • stain treating with such high viscosity fluids using squeeze-operated hand-held products can be difficult ergonomically.
  • One particular problem is how to dispense a high viscosity composition onto the stain treatment device so it may be applied to the stain.
  • Various devices are known, such as sponge applicators downstream of a dispensing orifice, whereby dispensing the fluid forces it through the sponge, however this is difficult with high viscosity fluids to get large amounts onto the stain treatment device.
  • the arrangement of invention allows the composition to be dispensed in the reservoir, such that it can be applied to the stain treatment device very easily and repeatedly for repeated loading with the composition which is useful for larger stains.
  • the dispensing/stain treatment part being positioned at the base of the reservoir, means the user does not need to invert the package to dispense and treat stains as gravity maintains the composition at the bottom of the container, ready for dispensing.
  • the dispensing device need not involve complicated and expensive seal/valves as the reservoir encloses the stain treatment device any drips are collected in the reservoir for later use. This also allows efficient emptying of the bottle when the composition is nearly all used up.
  • the stained area may present in any form such as discolouration, fading, darkening and may be due to soil or dirt or any other stain-creating substance.
  • stains affect localised areas (as opposed to the whole garment being affected) but can be quite large.
  • the treatment may precede a further operation such as a main washing operation. However it may also incorporate a rinsing process whereby the stain is simply treated and the stained area or whole fabric/article rinsed without a main wash.
  • the dispensing device may comprise a channel or duct or valve or aperture or any combination thereof.
  • the reservoir may be part of a closure and may also be used as a dosing device which can be placed in a washing machine along with the stained fabric (for a main wash or for a rinse etc) which has been pre-treated using the stain treatment device.
  • the reservoir preferably receives the stain treatment device to such a degree that the stain treatment device projects into the reservoir by more than 50% of the depth of the reservoir, and more preferably by more than 60%, even more preferably by more than 75% and most preferably by more than 90%.
  • the depth of the reservoir would preferably be the depth measured from the centre of the reservoir base to the top level of the reservoir sides at its highest point.
  • the depth would be measured along the longitudinal axis from the centre of the base which is the deepest part to the level of the sides - in Fig 1 this is shown from X to Y.
  • This feature means that the stain treatment device projects sufficiently deeply into the reservoir such that the stain treatment device is easily loaded with the composition.
  • the reservoir forms part of a closure device, this is especially advantageous, since it minimises the risk that inserting the stain treater into the reservoir activates any closure mechanism (e.g. by snap-fit engagement or screw-on screw-off) as screw-threads or snap-fit members become engaged by accident.
  • the stain treatment device may comprise a device allowing mechanical cleaning, such as a body with multiple projections.
  • the projections may be flexible so that they move during cleaning providing a light cleaning action. Alternatively some or all of the projections may be semi-rigid or rigid so as to provide a harsher mechanical cleaning action.
  • the projections may be thin e.g. bristles to provide a brush-like device, or thicker so as to provide finger like projections.
  • the stain treatment device comprises a generally hemispherical body with multiple projections extending radially therefrom.
  • the stain treatment device may itself be an extension of the dispensing device. So it may be continuous with e.g. a dispensing aperture, valve etc. It may comprise a surface surrounding said aperture or valve etc. so that it can be loaded with, so as to carry the composition which is then applied to the stained area without any scrubbing action as might be used with the above described devices containing projections.
  • the surface may be a ring (full or partial e.g. annular section) around the dispensing aperture.
  • the package may have a convex, preferably a curved e.g. hemispherical top to deter users from storing the bottle top-down. In this way the package is more likely to be stored in a stain treatment device - loading position i.e. with the flowable laundry composition accumulated by gravity in the base of the package.
  • the composition is preferably a shear thinning gel-type composition.
  • the viscosity under shear stress may be less than 300 Pa.s, preferably less than 100 Pa.s and more preferably less than 5 Pa.s, even more preferably it is at most 1 Pa.s and most preferably it is at most 0.5 Pa.s.
  • Shear thinning compositions may comprise a polymer gum, e.g. Xanthan gum or other gum capable of forming stable continuous gum networks which can suspend particles.
  • a polymer gum e.g. Xanthan gum or other gum capable of forming stable continuous gum networks which can suspend particles.
  • external structurants e.g. hydrogenated castor oil, micro crystalline cellulose may be used.
  • compositions may comprise a soap or fatty acid in combination with sodium sulphate and one or more surfactants may be used to form a gelled structure by the formation of lamellar phases.
  • the composition may comprise a lamellar phase dispersions from a micellar surfactant systems, and additionally a structurant for establishing the lamellar phase, whereby said structurant may be a fatty alcohol.

The composition may be provided in a concentrated form to be diluted or may be a ready-to-use (in-use) composition.

  • Viscosity was measured at varying shear rates from very low shear up to a shear regime in excess of 100 s -1 . Two situations are shown: the viscosity measured at relatively low shear (20 s -1 ) and that measured at much higher shear (100 s -1 ). It can be seen that the viscosity of composition A at high shear is much lower than that obtained at low shear, whereas composition B shows almost equal viscosity's for high and low shear. In other words composition A is clearly shear thinning, whereas composition B is not.
  • Tan delta values are shown, referring to the ratio of loss over storage moduli (G"/G') and reflecting the dominance of viscous over elastic properties such that materials giving very low “Tan delta”-values (tending to zero, such as composition A in the above table), will be much more elastic than those giving higher “Tan delta” values (tending to 90).
