Definitions

  • the present invention relates to a package or container for one or more water-soluble capsules containing a detergent composition.
  • Detergent compositions for machine washing of laundry are provided in many forms such as free-flowing powders, liquids. Detergents in the form of compressed powder tablets are also commonly available.
  • Tablets have several advantages over free-flowing powdered products and these are well documented, in particular, as they do not require measuring they are thus easier to handle and dispense into the wash load and allow for accurate dosing of detergent.
  • Water-soluble capsules generally comprise a detergent composition encapsulated with water-soluble film, such as polyvinyl alcohol. Encapsulation allows for handling without direct contact with the detergent composition. This is especially advantageous when the detergent composition includes aggressive cleaning components which would irritate the skin on direct contact.
  • a further problem is that many existing packages have been developed for other types of detergent e.g. boxes/bags from which free-flowing powder is scooped or bottles/refill bags from which the liquid is poured or boxes in which tablets are stacked. Whilst these may be adequate for packaging water-filled capsules they do not facilitate easy retrieval without the use of additional packaging which is undesirable for environmental reasons.
  • the invention provides one or more water-soluble capsules containing a detergent composition in combination with a package containing said one or more water-soluble capsules, characterised in that the package comprises a flexible material and is self-standing by means of a expandable base portion which expands from a collapsed position to an expanded position when one or more capsules is/are placed on the base, and is collapsible when empty so as to make the package substantially flat.
  • water soluble capsules may be packaged so as to facilitate easy retrieval of capsules from a standing package by simply reacting in and taking out a capsule/s.
  • the use of a self-standing package is especially advantageous in that it dispenses with the need for a separate supporting structure, (such as a box) when flexible materials are used.
  • the package comprises a single-walled body. This feature is advantageous as it minimises the amount of packaging material which is desirable for environmental reasons.
  • single-walled should be construed as meaning that at any position the package is only one wall thick. It includes a body comprising one or more co-joined walls and includes a wall or walls having a laminate structure.
  • the packaging material includes at least a portion (e.g. one or more walls) which is transparent or translucent.
  • This feature allows the capsules to be viewed through the packaging which is desirable especially when the capsules have an attractive shape or colour.
  • the package may have decoration applied there to, e.g. by printing, and this may be applied to transparent/translucent parts to allow some visibility of the capsules.
  • water-soluble capsules A further problem encountered with water-soluble capsules is that the water soluble film material is vulnerable to increased levels of ambient humidity during storage and this can lead to premature dissolution of the film and as a result the capsule may rupture and release it contents.
  • Another problem is that if, during storage, the film of the water soluble capsule becomes damp, it may then increase the possibility of in-wash lodging as a tacky film is more likely to stick to the washing machine door before it has chance to be caught up in the main wash.
  • the package is preferably formed from a material which has a Moisture Vapour Transfer Rate (M.V.T.R) of 0.25 g/m 2 /day to 10 g/m 2 /day at 38°C and 90% relative humidity and more preferably from 0.25 g/m 2 /day to 5 g/m 2 /day.
  • M.V.T.R Moisture Vapour Transfer Rate
  • This feature provides the additional advantage that the water soluble capsules can be protected from ambient humidity during storage.
  • the packaging system of the invention is intended to consist of a consumer unit containing the detergent composition of the invention and designed to be used/stored as such in the consumer homes.
  • the units shown are bags/pouches and can be made either from raw stock or from preformed and/or prefolded sheet material, and can be sealed by various means, e.g. by heat, adhesives/glue, tapes.
  • the bags/pouches herein are made of films, either monolayer, including coextruded materials, or laminated; such films are typically paper or plastic or combinations of the two; preferred materials for the bags herein are plastic and/or paper laminates.
  • Plastic, materials are typically polyolefines, and both plastic and paper can be virgin or recycled material; the films herein can be printed in different ways, typically gravure, flexo, offset.
  • films with moisture barrier properties obtained by resins, either coextruded or in different laminated layers, or coating by e.g. lacquers.
  • a combination of the invention comprising a plastic bag 1 which contains one or more water soluble capsules 3 (only one shown) of detergent liquid.
  • shaped water-soluble capsules may be used e.g. round, as shown in figures 1,3 and 4 or rectangular (sometimes referred to as 'pillow-shaped')as shown in figure 5.
  • the plastic bag 1 is constructed from a laminar material comprising two layers: an outer layer of polyester (PET) which is 12 microns thick and an inner layer of low linear density polyethylene(LLDPE) 150 microns thick.
  • PET polyester
  • LLDPE low linear density polyethylene
  • the bag has two rectangular side walls 2, 4 which are heat (or glue)-sealed together along corresponding longitudinal edges and which is closed at one end (the base portion 17) by a base wall 6 and at the other end (the upper portion 18) by 20, 22 seals both which are described below in greater detail.
  • a base wall 6 which is formed from a rectangular sheet of plastic, perimeter portions of which are heat (or glue)-sealed to respective edges portions of the end portions 8, 10 of the side walls 2,4.
  • the sealing portion 12 i.e. the part forming the seal with the base wall 6) is shaped such that the effective base area 16 is very generally elliptical (as shown more clearly in figure3).
  • a resealable closure member 20 which comprises a plastic zip 20 having corresponding engagement portions fixed on respective side walls 2, 4, internally of the bag 1.
  • the package further includes a permanent heat or glue seal 22 in the uppermost portion 18a.
  • a permanent heat or glue seal 22 in the uppermost portion 18a.
  • an indent 26 in the seal section 5 and/or 7, to assist tearing (along the dotted line 28, which may be weakened) so as to enable removal of the upper portion 18a (after purchase).
  • the bag 1 can then be opened and sealed/resealed repeatedly by use of the zip 20.
  • the bag 1 is self-standing on a substantially flat surface shown generally at 14, (and which could be for example a shelf, work top etc.,) when one or more capsules is/are placed on the base portion: the weight of the capsule acts downward on the base wall which thereby expands laterally to support the capsule and as a result the package is disposed in an upright position.
  • the construction as described above allows the bag to be formed one wall thick but self-standing and without a supporting structure such as a box.
  • the laminar material comprises two layers: an outer layer of polyester (PET) which is 12 microns thick and an inner layer of low linear density polyethylene(LLDPE) 180 microns thick.
  • PET polyester
  • LLDPE low linear density polyethylene
  • This material has an MVTR value of 4.50 g/m 2 /day at 38°C and 90% relative humidity.
  • This increased thickness of the LLDPE layer provides a reduced MVTR and additional stability for larger packs (e.g. where say 20 -30 or more capsules are packaged).
  • FIG. 4-7 A further embodiment is shown in figures 4-7.
  • This bag is structure as for the package above except that it has outwardly curved sides which provide extra volume.
  • the bag may have an increased outer curvature at the base so as to lower the centre of gravity of the package when one or more capsules, are contained so providing a more stable package.
  • the package of figures 4-7 may comprise any suitable material, such as that in the embodiment shown in figures 1-3.
  • the detergent liquid contained in the water soluble capsules exemplified here comprises: Raw material Level (weight percent of total) Nonionic Surfactant (alcohol ethoxylate) 20.00 Linear Dodecylbenzene Sulphonic Acid 20.00 Fatty acid 17.00 Monopropylene glycol 22.35 Monoethanolamine 9.65 Water, perfume, minor ingredients 11.00
  • capsules contain a granular laundry detergent powder as follows: Base powder Linear Dodecylbenzene Sulphonic Acid (Sodium salt) 8.8% Alcohol ethoxylate (C12 - C13 7 EO) 7.0% C16 -C18 Carboxylic acid 1.0% Zeolite 29.6% Anhydrous Sodium Carbonate 10.5% Moisture, Salts, Minors 4.1% (All above in a granulated Base Powder) Post-dosed ingredients Sodium Percarbonate 18.0% Tetracetyl ethylenediamine 3.5% Sodium Disilicate 5.5% Sodium Citrate 2.0% Fluorescer, antifoam, speckles, enzyme,fragrance, minors 10.0%
  • the detergent composition may take any suitable form e.g. any liquid, gel, granulated powder or combination thereof.
