Definitions

  • the present invention relates to packaging for low viscosity fabric treatment fluids which are dispensed by pouring into measuring devices which may themselves be emptied into further devices, such as a machine dispensing drawer or be placed directly into a washing receptacle such as a washing machine drum.
  • laundry packaging may incorporate an outlet from which the fluid is poured into dosing 'ball' or 'shuttle' which then is used to dose the laundry fluid into a washing receptacle or machine directly or via a dispensing drawer.
  • US 2012/004156 discloses a known fabric treatment composition having a viscosity in the range 200-1000 mPa.s @20s-1 and comprising a volatile benefit agent.
  • US 2003/051945 discloses a consumer package containing a fabric treatment fluid and comprising a reservoir containing the fluid, a dispensing outlet located in an uppermost portion of the package, a neck region comprising a mixing area adjacent and in fluid communication with the dispensing outlet and having an upwardly curved upper wall and curved side walls and a weir member bifurcating the reservoir region.
  • the present invention provides a consumer package according to claim 1.
  • the invention provides gently disrupted fluid flow to the mixing chamber prior to dispensing via the outlet.
  • the disruption increases the amount of volatile benefit agent released on dispensing whilst the viscosity together with the relative dimensions of the mixing chamber and the channels prevents excessive flow rates which could otherwise cause uncontrollable and potentially eruptive egress of the fluid. It is important that disruption occurs within the mixing chamber and not during pouring. At the same time, the smoothly curved walls prevent pooling of viscous gels in corners. The weir also reduces the upstream water velocity which prevents uncontrollable fluid egress.
  • the release of the volatile benefit agent advantageously provides for enhanced consumer experience of that benefit agent and also 'primes' the consumer for enhanced enjoyment during subsequent activities e.g.
  • the fluid may be a liquid or a gel.
  • the gel is pourable.
  • the pack comprises a base portion, and this is at an opposite end to the dispensing portion, and the pack is stored standing on its base portion.
  • the terms "tipped” and “tipped orientation” as used herein are intended to mean that that the packaging is tilted or rotated by the consumer from an upright orientation to lie in at least a horizontal orientation, and preferably rotated beyond this so that the base is higher than the dispensing outlet whereby fluid of the stated viscosity flows from the reservoir to the dispensing outlet is effected or at least aided by gravity.
  • a squeeze-activated package without or even against gravity is also included in the invention and with such embodiments, tipping would not need to place the dispensing outlet lower than the reservoir.
  • the weir comprises an internal wall, and preferably a smoothly curved or flat internal wall. This enhances the effect of the weir to disrupt the flow.
  • the package comprises an external recess defined by one or more walls, and preferably the weir is provided by said one or more walls of the external recess.
  • external recess means that it is a recess applied to and visible from the outside of the package, as opposed to the reservoir which is an internal space within the interior of the package.
  • the external recess comprises a channel, traversing the package transversely.
  • the recess is substantially tubular and is substantially circular in cross section.
  • the package comprises a walled structure and the recess traverses the package from one wall to another, preferably a front wall to a rear wall.
  • the recess is located substantially horizontally central of the walls, so at a midpoint along a level/horizontal axis (when the pack is viewed standing upright on a level base). Centrality is preferably measured using a diametric horizontal line through the centre of the recess and then centralizing this line within the wall. Most preferably the centrality is such that the weir substantially bisects the neck region. This is highly advantageous where both the weir and/or recess are symmetrical.
  • the weir is located nearer an upper dispensing outlet than the base and more preferably it is in an upper region, where "upper” refers to measuring along an upright axis with the pack supported on its base with the dispensing outlet at an opposite end.
  • the neck portion is preferably tapered in the direction of the dispensing outlet to restrict and /or tapers the diameter of the channels and ensures each is oriented in a direction toward the mixing chamber and dispensing outlet ready where mixing takes place prior to dispensing.
  • the neck region may be present as a high waist to afford the package a carafe structure. This affords a larger reservoir section downstream of the weir, with a good quantity of fluid their and a smaller mixing chamber.
  • the neck region is preferably offset from a central postion to allow for ease of pouring.
  • the mixing chamber is preferably 0.03 - 0.05 m high, and most preferably 0.035 - 0.045 m high.
  • the mixing chamber is preferably 0.03 - 0.05 deep, most preferably 0.035 - 0.045 m, when viewed from either side.
  • the mixing chamber is preferably 0.055 - 0.07 wide, most preferably 0.060 - 0.065m, when viewed from the front or the rear. This provides an advantageous mixing volume for disruption and flow performance with the viscosity range of the invention.
  • the package may be elongate (such as a bottle) and the dispensing outlet may be offset from a central longitudinal axis of the package.
  • the dispensing outlet may comprise a spout.
  • the dispensing outlet may be part of a bottle fitment comprising a collar arrangement with a spout and optionally a drain back aperture.
  • the package may comprise further recesses or apertures acting as handles. Preferably these are located downstream of the weir member, ("downstream” being construed in the context of fluid flowing from the reservoir to the dispensing aperture). When viewed stood on a level surface, the weir should be higher than any additional handle apertures.
  • the package may be a bottle, carton, tube, cavat etc.
  • the recess may comprise a through-hole or be a 'blind' recess such that one end is closed off e.g. by a package wall.
  • the package comprises rigid portions such that the reservoir aperture is self supporting.
  • the recess is provided in said rigid portions.
  • the package may further comprise a dosing device comprising a dosing recess, the device being releasably retained in the reservoir recess such that the respective recesses are in a nested configuration.
  • the volatile benefit agent is an agent which is volatile and which confers a benefit to fabric.
  • Suitable volatile benefit agents include but are not limited to perfumes, insect repellents, essential oils, sensates such as menthol and aromatherapy actives, preferably perfumes. Mixtures of volatile benefit agents may be used.
  • the total amount of volatile benefit agent is preferably from 0.01 to 10 % by weight, more preferably from 0.05 to 5 % by weight, even more preferably from 0.1 to 4.0 %, most preferably from 0.15 to 4.0 % by weight, based on the total weight of the fluid.
  • the preferred volatile benefit agent is a perfume.
  • the consumer experience is greatly enhanced by a greater perfume sensation and this then 'primes' the consumer for enhanced enjoyment of the particular perfume during later activities e.g. during hand washing or after washing and drying when handling the fabrics.
  • the volatile benefit agent or at least a portion of said agent evaporates at room temperature.
  • the perfumes of the of the invention preferably comprise an unconfined (also called non-encapsulated) volatile benefit agent.
  • the volatile benefit agent is a perfume
  • the perfumes described below are suitable for use as the encapsulated volatile benefit agent and also as the unconfined perfume component.
  • Any suitable perfume or mixture of perfumes may be used.
  • Useful components of the perfume include materials of both natural and synthetic origin. They include single compounds and mixtures.

Jacobs, edited by Van Nostr and; or Perfume and Flavor Chemicals by S. Arctander 1969, Montclair, N.J. (USA ).
  • perfume in this context is not only meant a fully formulated product fragrance, but also selected components of that fragrance, particularly those which are prone to loss, such as the so-called 'top notes'.

  • materials, of relatively low boiling point and relatively low Clog P have been called the "delayed blooming" perfume ingredients and include the following materials:
  • Preferred non-encapsulated perfume ingredients are those hydrophobic perfume components with a ClogP above 3.
  • ClogP means the calculated logarithm to base 10 of the octanol/water partition coefficient (P).
  • the octanol/water partition coefficient of a perfume raw material (PRM) is the ratio between its equilibrium concentrations in octanol and water. Given that this measure is a ratio of the equilibrium concentration of a PRM in a non-polar solvent (octanol) with its concentration in a polar solvent (water), ClogP is also a measure of the hydrophobicity of a material--the higher the ClogP value, the more hydrophobic the material.
  • ClogP values can be readily calculated from a program called "CLOGP" which is available from Daylight Chemical Information Systems Inc., Irvine Calif., USA. Octanol/water partition coefficients are described in more detail in U.S. Pat. No. 5,578,563 .
