Definitions

  • the present invention concerns a consumer unit for dyeing textile.
  • a dyeing product comprising a dyeing agent
  • a water based solution in which the textile, such as while clothes are added for a certain period of time.
  • the dyeing can be done, e.g., either by giving a white textile a color or by reinforcing the existing color of the textile. For instance a blue jeans which has acquired a pale color over the time due to washing can be treated with a blue dyeing product to reinforce its color so that it can look like new, at least regarding to the color.
  • a bleaching agent to bleach the color of a textile so that this textile can be latter on dyed with a different dye resulting in a different color. The change of color allows a user to choose its preferred color for chosen clothes.
  • a consumer unit for the dyeing of textiles is a bag, e.g. a flow pack, comprising a certain amount of dyeing product.
  • the bag needs to be open and the product dispensed into a bucket into which the fabric will be treated.
  • the consumer unit may also comprise a paper box containing the bag.
  • This kind of known consumer unit has the disadvantage that the consumer has to open the bag and dispense its content, the handling of the bag is cumbersome and often ends into the consumer having direct contact with the dyeing product, and/or the product being partially spilled out of the bucket during dispensing.
  • US 2009/249562 A1 is describing a consumer product for dying textiles with a reactive dye composition for rejuvenation of the color or dark colored textile fabrics.
  • a reactive dye composition for rejuvenation of the color or dark colored textile fabrics.
  • the dye composition it is preferably used together with a dosing container comprising an opening which could be closed by a corresponding removable cap.
  • the dosing container with the dye is used preferably within a usual laundry washing machine to rejuvenate the textile fabrics. Even such a dying product is showing some deficiencies with regard to convenience, usability and a tamper-proof packaging.
  • WO 90/12864 A1 is showing a cleaning product for textile fabrics which is used within a usual laundry washing machine.
  • the cleaning composition is stored and used within a dosing container comprising an opening closed by a water-soluble or water-dispersible closure member.
  • a dosing container comprising an opening closed by a water-soluble or water-dispersible closure member.
  • the container is opened after contact of the closure member with water.
  • the consumer unit according to the invention is easy to use, and can easily be placed inside the drum of a washing machine, without a user needing to dispense its content.
  • the objective of the invention is solved by a consumer unit for use in a washing machine for dyeing textile.
  • the consumer unit comprises a textile dyeing agent stored in a crucible.
  • the crucible comprises a bottom and an opening arranged at the other end from the bottom.
  • the opening is round, such as oval, and preferably circular.
  • the crucible further comprises a circumferential wall between the bottom and the opening.
  • the crucible preferably has a general shape of a body of revolution.
  • the opening is surrounded by an annular surface extending in a plane, and a lid is attached to the annular surface thereby closing the opening.
  • the crucible is formed as a single piece. A single piece is more stable and less unlikely to break during laundry treatment process. Breaking or falling apart of pieces from the crucible should be avoided because these parts may generate non foreseen noise during treatment in a drum. Further the crucible is insoluble in water.
  • the crucible is preferably made of a material which can be blow molded, such as a polypropylene based composition.
  • a crucible which is insoluble in water has the advantage that is does not interfere in, i.e. it does not reduce, the relative concentration of the dyeing agent in the treatment solution.
  • the treatment solution is the solution resulting when the dyeing product is dissolved in water.
  • a tear-off sleeve allows information to be shown on the outer surface of the crucible, while it can be removed before use. It was found that using a consumer unit with removed sleeve in a wash machine drum has advantages, because no dyeing agent can be left stuck between crucible and sleeve, thus the whole process can be done in a much cleaner way and more complete way. Further the tear-off sleeve covers at least part of the lid, such that the lid can only be removed, after said sleeve is removed. Therefore an enhanced protection can be given to the whole consumer unit because the sleeve also works as a tamper evident, also giving a better aesthetical appearance.
  • the crucible is barrel shaped so that the bottom and the opening, are, each, smaller than a largest portion of the crucible. It is further preferred that the greatest annular perimeter of the crucible is at a location between the bottom and the opening, preferably at a distance of at least 1/5 of the height of the crucible from each of the bottom and from the opening. This provides a good dynamic of the crucible into the washing machine, since the largest part of the barrel can absorb chocks much better than the corners from bottom and/or opening.
  • the amount of the dyeing product is a single unit dose.
  • a single unit dose is preferably sufficient to fully dye at least 250g of cotton textile.
  • Such dose preferably has a mass of greater than 100 g, preferably between 150 g and 3 Kg, more preferably between 200 g and 500 g.
  • the dyeing product in the crucible comprises the dye composition and the dye fix, preferably as a mixture.
  • the lid is a sheet like material. It is attached to the annular surface so that it can be peeled off by a consumer. Due to the difference in materials of the crucible with a form stable material and the lid which is flexible and can easily be rolled or folded, the step of opening the crucible is made simple for a user. The user can hold the crucible, peel off the lid, and move the crucible to its place of use in a convenient way, with low efforts, without spilling out and/or entering into skin contact with the dyeing agent. In this case it is preferred that the lid is water insoluble.
  • the lid is water soluble.
  • a soluble lid is a foil based on polyvinyl alcohol (PVA), such foils are available with diverse temperatures and solubility rates. A crucible closed with such foil can be added directly to a washing machine's drum, without a user needing to peel it off.
  • PVA polyvinyl alcohol
  • the lid may be thermoformed.
  • the dyeing product comprises less than 0.01weigth% of surfactant. Higher concentrations of surfactants would disturb the dyeing process. With less than 0.01weigth% of surfactant, in the dyeing product, best dyeing actions can be obtained.
  • the dyeing product comprises less than 0.01weigth% of bleach. Bleach do react with most of the dyes or their precursors thus interfering negatively with the dyeing.
  • the dyeing product comprises less than 0.01weigth% of enzyme. It is believed that enzymes interfere with the dyeing process.
  • the annular surface is continuous, meaning uninterrupted, so as to allow for a tight sealing of the opening by the lid.
  • the consumer unit preferably, comprises a booklet.
  • Such booklet can be used to provide the instructions of how to use the product.
  • the booklet comprises a color matching pattern, of at least 2 cm2, preferably of at least 4 cm2.
  • the user can place close to a piece of fabric to observe the color the textile will have after the dyeing the textile.
  • the booklet is placed over the lid, preferably secured in place by a sleeve, which covers at least part of the booklet and lid.
  • the booklet has a counter at least partially matching the contour of the lid.
  • the booklet may have rounded corners.
  • the crucible preferably comprise a transition corner located between the wall and the annular surface, wherein the corner preferably has a minor radius of greater than 0,3 mm, more preferably greater than 3 mm.
  • the wall transitions into the annular surface at the transition corner.
  • the crucible comprises a transition surface between the transition corner and the annular surface.
  • the annular surface is offset (a) out of plane from the transition surface. The offset is away from the crucible's interior. Due to the offset, the annular surface forms a well-defined region for which the lid can be attached, and therefore detached, to the crucible.
  • the offset (a) is preferably smaller than the smallest distance (b) between the annular surface and the transition corner. Due to the relatively low offset, the annular surface is less prone to hit the drum of a washing machine when this machine is operating.
  • the preferred use of the consumer unit according to the invention is in a washing machine.
  • the normal washing cycle program of the washing machine can be used for dyeing.
  • the term "reactive dye” is intended to mean that a reactive substituent group in the dye molecule can form a covalent chemical bond with molecules in the fabric to be dyed.
  • the terms “dyeing agent” and “reactive dye” can be interchanged when the dyeing agent is of the reactive kind. Reactive dyes are the most suitable dyes for home use as they work at a low temperature, give color fast results and do not stain the washing machine.
  • Suitable reactive dyes include those from the triazine, pyrimidine and vinyl derivative classes, having the following formulae: wherein A ⁇ 1 is CI and A ⁇ 2 is aryl or Cl, preferably Cl;
  • aryl means a monocyclic or polycyclic-aromatic ring or ring radical comprising carbon and hydrogen atoms and which may be substituted or unsubstituted.
  • suitable aryl groups include, but are not limited to, phenyl, tolyl, anthracenyl, fluorenyl, indenyl, azulenyl, and naphthyl, as well as benzo-fused carbocyclic moieties such as 5,6,7,8-tetrahydronaphthyl.
