Definitions

  • the present invention relates to concentrated particulate detergent compositions in visually appealing packaging according to the preamble of claim 1.
  • Concentrated particulate formulations offer huge environmental and cost savings. A major saving arises from the reduced package size, however, this itself presents the problem that the package is therefore less noticeable on shelf in a retail establishment. In order to overcome this visually interesting packaging can be employed however this often involves additional material which itself negates any environmental savings achieved by increased concentration of the particulate composition.
  • D 1 US 4 269 722 A discloses a bottled particulate detergent of certain particle sizes, bulk density and flowability contained in a necked bottle in which the the neck opening is sufficiently small as to allow ready sealing with screwcaps conventionally employed to close bottles while also allowing pouring from the bottle of the particulate detergent of the described characteristics.
  • D2 US 7 022 660 discloses a process for preparing a detergent particle having a coating layer of a water-soluble material is provided.
  • the process comprises providing a particle core of a detergent active material and the particle core is then at least partially covered by a particle coating layer of a water soluble coating material including double salt combinations of alkali metal carbonates and sulfates that reduces the surface area of the particle
  • D3 EP 1 081 219 A2 discloses a process for preparing a detergent particle having a coating layer of a water-soluble material.
  • the process comprises providing a particle core of a detergent active material and the particle core is then at least partially covered by a particle coating layer of a water soluble coating material including double salt combinations of alkali metal carbonates and sulfates that reduces the surface area of the particle.
  • An object of the invention is therefore to provide a packaged concentrated particulate detergent product which has visual interest but which reduces package material waste.
  • a packaged product according to claim 1 According to one aspect of the invention, a packaged product according to claim 1.
  • the combination according to the invention is advantageous in that it provides visually appealing concentrated particulate packaged product without excessive material. This is achieved by the combination of the coated particles and the transparent packaging.
  • the inner surfaces of the reservoir become coated with a fine dusting, which would affect the transparency. For this reason, traditionally powders are mostly sold in opaque cartons or pouches.
  • the large hard-coated particles of the invention do not for film over the reservoir surface.
  • the coating reduces the stickiness of the hygroscopic surfactant core to a point where the particles are free flowing across a surface. This together with the particle size means that any composition left in the package after tipping/pouring etc. are present in minor and localised amounts - which does not alter the transparency. A gentle tap releases them from the surface.
  • the or each transparent portion includes a base portion of the pack.
  • the or each transparent portion may extend longitudinally to include a base portion.
  • the or each transparent portion may comprise the as such that in plan view the package appears totally transparent. This has the advantage of communicating to the consumer the lack of fines whilst at the same time presenting a visually appealing pack, even if the package is tipped over to pour composition into a receptacle.
  • the package is sufficiently rigid in material or construction such that a portion e.g. the base or a side wall, can be tapped to move the particles throughout the reservoir. Such tapping creates audible feedback to the user to guide them as to the movement of the particles.
  • a rigid plastic bottle or tub or even a sachet would be advantageous.
  • the or each transparent portion comprises at least a part of the front face, such that the composition contained within is visible when viewed looking at front face (being the face normally front facing when placed on shelf either in a retail establishment or even at home).
  • the or each transparent portion comprises more than 50% of the surface area of the pack. More preferably the or each transparent portion comprises more than 60% of the surface area of the pack. Most preferably the or each transparent portion comprises more than 75% of the surface area of the pack.
  • transparent means that its light transmittance is greater than 25% at wavelength of about 410-800 nm.
  • the or each transparent portion 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).
  • absorbency of transparent layer may be measured as less than 0.6 (approximately equivalent to 25% transmitting) or by having transmittance greater than 25% wherein % transmittance equals: 1 10 absorbency ⁇ 100 %
  • absorbency of the opaque layer may be measured as more than 0.6.
  • the container is considered to be transparent.
  • absorbency of bottle may be measured as less than 0.6 (approximately equivalent to 25% transmitting) or by having transmittance greater than 25% wherein % transmittance equals: 1 10 absorbency x 100% and corresponding absorbency levels for the remaining preferred levels above.
  • Suitable materials for 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 packaged particles are substantially the same shape and size as one another.
  • This homogeneity can be viewed through the or each transparent portions and has great visual appeal.
  • the amount of coating on each coated particle is advantageously from 10 to 45, more preferably 20 to 35% by weight of the particles.
  • the number percentage of the packaged composition of particles comprising the core and coating is preferably at least 85%.
  • the coating comprises water soluble inorganic salt.
  • the coated particles preferably comprise from 0.001 to 3 wt% perfume.
  • the core of the coated particles preferably comprises less than 5 wt%, even more preferably less than 2.5 wt% inorganic materials.
  • the coating is preferably sodium carbonate, optionally in admixture with a minor amount of SCMC and further optionally in admixture with one or more of sodium silicate, water soluble fluorescer, water soluble or dispersible shading dye and pigment or coloured dye.
  • Each particle has perpendicular dimensions x, y and z, wherein x is from 0.2 to 2 mm, y is from 2.5 to 8mm (preferably 3 to 8 mm), and z is from 2.5 to 8 mm (preferably 3 to 8 mm),
  • the particles are desirably oblate spheroids with diameter of 3 to 6 mm and thickness of 1 to 2 mm.
  • At least some, and preferably a major portion by number of the particles are coloured other than white which has a greater visual effect. Multicoloured, e.g. some blue and some white, particles have been found to provide even higher visual appeal.
  • the cooled dried output from the evaporator or drier stage (b) comprising at least 95 wt% preferably 96 wt%, more preferably 97 wt%, most preferably 98 wt% surfactant to be transferred to a mill and milled to particles of less than 1.5 mm, preferably less than 1 mm average diameter before it is fed to the extrusion step (c).
  • a powdered flow aid such as Aerosil®, Alusil®, or Microsil®, with a particle diameter of from 0.1 to 10 ⁇ m may be added to the mill in an amount of 0.5 to 5 wt%, preferably 0.5 to 3 wt% (based on output from the mill) and blended into the particles during milling.
  • step b or the intermediate milling step, if used, is fed to the extruder, optionally along with minor amounts (less than 10 wt% total) of other materials such as perfume and/or fluorescer, and the mixture of materials fed to the extruder is extruded to form an extrudate with a diameter of greater than 2 mm, preferably greater than 3 mm, most preferably greater than 4 mm and preferably with a diameter of less than 7 mm, most preferably less than 5 mm, while periodically cutting the extrudate to form hard detergent particles with a maximum thickness of greater than 0.2 mm and less than 3 mm, preferably less than 2 mm, most preferably less than about 1.5 mm and more than about 0.5 mm, even 0.7 mm.
  • the invention also encompasses other cross sections such as triangular, rectangular and even complex cross sections, such as one mimicking a flower with rotationally symmetrical "petals".
  • the invention can be operated on any extrudate that can be forced through a hole in the extruder or extruder plate; the key being that the average thickness of the extrudate should be kept below the level where dissolution will be slow. As discussed above this is a thickness of about 2 mm. Desirably multiple extrusions are made simultaneously and they may all have the same cross section or may have different cross sections. Normally they will all have the same length as they are cut off by the knife.
  • the cutting knife should be as thin as possible to allow high speed extrusion and minimal distortion of the extrudate during cutting.
  • the extrusion should preferably take place at a temperature of less than 45°C, more preferably less than 40°C to avoid stickiness and facilitate cutting.
  • the extrudates according to the present process are cut so that their major dimension is across the extruder and the minor dimension is along the axis of the extruder. This is the opposite to the normal extrusion of surfactants. Cutting in this way increases the surface area that is a "cut" surface. It also allows the extruded particle to expand considerably along its axis after cutting, whilst maintaining a relatively high surface to volume ratio, which is believed to increase its solubility and also results in an attractive biconvex, or lentil, appearance. Elsewhere we refer to this shape as an oblate spheroid. This is essentially a rotation of an ellipse about its minor axis.
  • the LAS containing surfactant blends can be extruded to make solid detergent particles that are hard enough to be used without any need to be structured by inorganic materials or other structurants as commonly found in prior art extruded detergent particles.
  • the amount of surfactant in the detergent particle can be much higher and the amount of builder in the detergent particle can be much lower.
  • the blend in step (a) comprises at least about 60 wt%, most preferably at least about 70 wt% surfactant and preferably at most about 40 wt%, most preferably at most 30 wt% water, the surfactant part consisting of at least 51 wt% linear alkyl benzene sulphonate salt (LAS) and at least one co-surfactant;
  • the co-surfactant is chosen from the group consisting of: SLES, and nonionic, together with optional soap and mixtures thereof.
  • the upper limit for the amount of nonionic surfactant has been found to be 20 wt% of the total surfactant to avoid the dried material being too soft and cohesive to extrude because it has a hardness value less than 0.5 MPa.
  • the surfactant blend is dried in step (b) to a moisture content of less than 1.2 wt%, more preferably less than 1.1 wt%, and most preferably less than 1 wt%.
  • Drying may suitably be carried out using a wiped film evaporator or a Chemithon Turbo Tube® drier.
  • the extruded hard detergent particles may be coated by transferring them to a fluid bed and spraying onto them up to 40 wt% (based on coated detergent particle) of inorganic material in aqueous solution and drying off the water.
  • the coating material is not contributing to the wash performance of the composition then it is desirable to keep the level of coating as low as possible, preferably less than 35 wt% even less than 30 wt%, especially for larger extruded particles with a surface area to volume ratio of greater than 4 mm -1 .
  • the detergent composition comprises at least 70 wt%, preferably at least 85 wt% of coated particles made using the process. However, compositions with up to 100 wt% of the particles are possible when basic additives are incorporated into the extruded particles, or into their coating.
  • the composition may also comprise, for example, an antifoam granule.
  • the coating is coloured. Particles of different colours may be used in admixture, or they can be blended with contrasting powder. Of course, particles of the same colour as one another may also be used to form a full composition. As described above the coating quality and appearance is very good due to the excellent surface of the cut extrudates onto which the coating is applied in association with the large particle size and S/V ratios of the preferred particles.
  • the detergent particles comprise perfume.
  • the perfume may be added into the extruder or premixed with the surfactant blend in the mill, or in a mixer placed after the mill, either as a liquid or as encapsulated perfume particles.
  • the perfume may be mixed with a nonionic material and blended. Such a blend may alternatively be applied by coating the extruded particles, for example by spraying it mixed with molten nonionic surfactant.
  • Perfume may also be introduced into the composition by means of a separate perfume granule and then the detergent particle does not need to comprise any perfume.
  • the composition comprises greater than 50 wt% detergent surfactant.
  • Surfactant blends that do not require builders to be present for effective detergency in hard water are preferred. Such blends are called calcium tolerant surfactant blends if they pass the test set out hereinafter. Thus, it may be advantageous if the extruded core is made using a calcium tolerant surfactant blend according to the test herein described.
  • the detergent may also be of use for washing with soft water, either naturally occurring or made using a water softener. In this case, calcium tolerance is no longer important and blends other than calcium tolerant ones may be used.
  • LAS can be at least partially replaced by MES, or, less preferably, partially replaced by up to 20 wt% PAS.
  • the surfactants are mixed together before being input to the drier. Conventional mixing equipment is used.
  • scraped film devices may be used.
  • a preferred form of scraped film device is a wiped film evaporator.
  • One such suitable wiped film evaporator is the "Dryex system" based on a wiped film evaporator available from Ballestra S.p.A..
  • Alternative drying equipment includes tube-type driers, such as a Chemithon Turbo Tube® drier, and soap driers.
  • the hot material exiting the scraped film drier is subsequently cooled and broken up into suitable sized pieces to feed to the extruder. Simultaneous cooling and breaking into flakes may conveniently be carried out using a chill roll. If the flakes from the chill roll are not suitable for direct feed to the extruder then they can be milled in a milling apparatus and/or they can be blended with other liquid or solid ingredients in a blending and milling apparatus, such as a ribbon mill. Such milled or blended material is desirably of particle size 1 mm or less for feeding to the extruder.
  • Particulate material with a mean particle size of 10 nm to 10 ⁇ m is preferred for use as a milling aid.
  • materials there may be mentioned, by way of example: aerosil®, alusil®, and microsil®.
  • the extruder provides further opportunities to blend in ingredients other than surfactants, or even to add further surfactants.
  • all of the anionic surfactant, or other surfactant supplied in admixture with water; i.e. as paste or as solution, is added into the drier to ensure that the water content can then be reduced and the material fed to and through the extruder is sufficiently dry.
  • Additional materials that can be blended into the extruder are thus mainly those that are used at very low levels in a detergent composition: such as fluorescer, shading dye, enzymes, perfume, silicone antifoams, polymeric additives and preservatives.
  • Solid additives are generally preferred. Liquids, such as perfume may be added at levels up to 2.5 wt%, preferably up to 1.5 wt%. Solid particulate structuring (liquid absorbing) materials or builders, such as zeolite, carbonate, silicate are preferably not added to the blend being extruded. These materials are not needed due to the self structuring properties of the very dry LAS-based feed material. If any is used the total amount should be less than 5 wt%, preferably less than 4 wt%, most preferably less than 3 wt%. At such levels no significant structuring occurs and the inorganic particulate material is added for a different purpose, for instance as a flow aid to improve the feed of particles to the extruder.
  • the output from the extruder is shaped by the die plate used.
  • the extruded material has a tendency to swell up in the centre relative to the periphery.
  • An advantageous variant of the process takes the sliced extruded particles and coats them. This allows the particles to be coloured easily. It also further reduces the stickiness of the hygroscopic surfactant core to a point where the particles are free flowing. Coating makes them more suitable for use in detergent compositions that may be exposed to high humidity for long periods.
  • the thickness of coating obtainable by use of a coating level of say 5 wt% is much greater than would be achieved on typically sized detergent granules (0.5-2mm diameter sphere).
  • the extruded particles can be considered as oblate spheroids with a major radius "a” and minor radius "b".
  • this surface area to volume ratio must be greater than 3 mm-1.
  • the coating thickness is inversely proportional to this coefficient and hence for the coating the ratio "Surface area of coated particle" divided by "Volume of coated particle” should be less than 15 mm-1.
  • any known coating may be used, for instance organic, including polymer
  • An aqueous spray-on of coating solution in a fluidised bed may also generate a further slight rounding of the detergent particles during the fluidisation process.
  • Suitable inorganic coating solutions include sodium carbonate, possibly in admixture with sodium sulphate, and sodium chloride. Food dyes, shading dyes, fluorescer and other optical modifiers can be added to the coating by dissolving them in the spray-on solution or dispersion.
  • Use of a builder salt such as sodium carbonate is particularly advantageous because it allows the detergent particle to have an even better performance by buffering the system in use at an ideal pH for maximum detergency of the anionic surfactant system. It also increases ionic strength, which is known to improve cleaning in hard water, and it is compatible with other detergent ingredients that may be admixed with the coated extruded detergent particles.
  • the amount of coating should lie in the range 3 to 50 wt% of the particle, preferably 20 to 40 wt% for the best results in terms of anti-caking properties of the detergent particles.
  • the coated particles dissolve easily in water and leave very low or no residues on dissolution, due to the absence of insoluble structurant materials such as zeolite.
  • the coated particles have an exceptional visual appearance, due to the smoothness of the coating coupled with the smoothness of the underlying particles, which is also believed to be a result of the lack of particulate structuring material in the extruded particles.
  • the coated detergent particle is curved.
  • the size is such that y and z are at least 3 mm, preferably 4 mm, most preferably 5 mm and x lies in the range 1 to 2 mm.
  • the coated detergent detergent particle may be shaped as a disc.
  • the core is primarily surfactant. It may also include detergency additives, such as perfume, shading dye, enzymes, cleaning polymers and soil release polymers.
  • the coated detergent particle preferably comprises between 50 to 90 wt% of a surfactant, most preferably 70 to 90 wt %.
  • a surfactant most preferably 70 to 90 wt %.
  • the nonionic and anionic surfactants of the surfactant system may be chosen from the surfactants described " Surface Active Agents" Vol. 1, by Schwartz & Perry, Interscience 1949 , Vol. 2 by Schwartz, Perry & Berch, Interscience 1958 , in the current edition of " McCutcheon's Emulsifiers and Detergents” published by Manufacturing Confectioners Company or in " Tenside Taschenbuch", H. Stache, 2nd Edn., Carl Hauser Verlag, 1981 .
  • the surfactants used are saturated.
  • Suitable anionic detergent compounds that may be used are usually water-soluble alkali metal salts of organic sulphates and sulphonates having alkyl radicals containing from about 8 to about 22 carbon atoms, the term alkyl being used to include the alkyl portion of higher acyl radicals.
  • suitable synthetic anionic detergent compounds are sodium and potassium alkyl sulphates, especially those obtained by sulphating higher C8 to C18 alcohols, produced for example from tallow or coconut oil, sodium and potassium alkyl C9 to C20 benzene sulphonates, particularly sodium linear secondary alkyl C10 to C15 benzene sulphonates; and sodium alkyl glyceryl ether sulphates, especially those ethers of the higher alcohols derived from tallow or coconut oil and synthetic alcohols derived from petroleum.
  • anionic surfactants are sodium lauryl ether sulphate (SLES), particularly preferred with 1 to 3 ethoxy groups, sodium C10 to C15 alkyl benzene sulphonates and sodium C12 to C18 alkyl sulphates.

  • the anionic surfactant is present in the coated detergent particle at levels between 15 to 85 wt%, more preferably 50 to 80 wt%.
  • Suitable non-ionic detergent compounds which may be used include, in particular, the reaction products of compounds having a hydrophobic group and a reactive hydrogen atom, for example, aliphatic alcohols, acids, amides or alkyl phenols with alkylene oxides, especially ethylene oxide either alone or with propylene oxide.

  • surfactants are mixed together before being dried. Conventional mixing equipment may be used.
  • the surfactant core of the detergent particle may be formed by roller compaction and subsequently coated with an inorganic salt.

Such blends are called calcium tolerant surfactant blends if they pass the test set out hereinafter. However, the invention may also be of use for washing with soft water, either naturally occurring or made using a water softener. In this case, calcium tolerance is no longer important and blends other than calcium tolerant ones may be used.
  • Suitable calcium tolerant co-surfactants include SLES 1-7EO, and alkyl ethoxylate non-ionic surfactants, particularly those with melting points less than 40°C.
  • a LAS/SLES surfactant blend has a superior foam profile to a LAS Nonionic surfactant blend and is therefore preferred for hand washing formulations requiring high levels of foam.
  • SLES may be used at levels of up to 30%.
  • a LAS/NI surfactant blend provides a harder particle and its lower foam profile makes it more suited for automatic washing machine use.
  • the main component of the coating is the water soluble inorganic salt.
  • Other water compatible ingredients may be included in the coating.
  • fluorescer for example fluorescer, SCMC, shading dye, silicate, pigments and dyes.

  • Sequestrants may be present in the detergent particles.
  • coated large detergent particles are manufactured, following the process in PCT/EP2010/055256 .
  • Surfactant raw materials were mixed together to give a 67 wt% active paste comprising 85 parts LAS (linear alkyl benzene sulphonate), 15 parts Nonionic Surfactant.
  • the raw materials used were:
  • the dried surfactant blend dropped onto a chill roll, where it was cooled to less than 30°C.
  • the cooled dried surfactant blend particles were milled using a hammer mill, 2% Alusil® was also added to the hammer mill as a mill aid.
  • the resulting milled material is hygroscopic and so it was stored in sealed containers.
  • the average particle diameter and thickness of samples of the extruded particles were found to be 4.46 mm and 1.13 mm respectively.
  • the standard deviation was acceptably low.
  • Coated particles composition is given in Table 4.
  • coated extruded particles have an excellent appearance due to their high surface smoothness. Without wishing to be bound by theory it is thought that this is because the uncoated particles are larger and more flattened than usual detergent particles and that their core has a much lower solids content than usual (indeed it is free of solid structuring materials, unlike prior art coated extruded particles).
  • the BD container was fitted with a removable collar to extend the height of the container. This extended container was then filled via the poured BD technique. The extended container was then placed on a Retsch Sieve Shaker and allowed to vibrate/tap for 5 min using the 0.2mm/"g" setting on the instrument. The collar was then removed and the excess powder levelled as per the standard BD measurement, the mass of the container measured and the Tapped BD calculated in the usual way.
  • Standard DFR Dynamic Flow Rate
  • a cylindrical glass tube having an internal diameter of 35 mm and a length of 600 mm.
  • the tube is securely clamped with its longitudinal axis vertical. Its lower end is terminated by means of a smooth cone of polyvinyl chloride having an internal angle of 15 DEG and a lower outlet orifice of diameter 22.5 mm.
  • a beam sensor is positioned 150 mm above the outlet, and a second beam sensor is positioned 250 mm above the first sensor.
  • the outlet orifice is temporarily closed, for example, by covering with a piece of card, and detergent composition is poured into the top of the cylinder until the detergent composition level is about 100 mm above the upper sensor.
  • the outlet is then opened and the time t (seconds) taken for the detergent composition level to fall from the upper sensor to the lower sensor is measured electronically.
  • the DFR is the tube volume between the sensors, divided by the time measured.
  • Uncoated crystals do however, flow much better than the uncoated prior art powders. It is thus feasible to use a small proportion of uncoated crystals in the composition, say up to 30% of the total particles, preferably up to 15 % by number.
  • the coated crystals despite their superior appearance to the uncoated crystals have a lower DFR then the uncoated ones, hence the coating is improving appearance but not the flow.
  • the coated crystals do have a very consistent DFR as seen in table 3 (in fact they seem to flow the same way reliably no matter what their history).
  • both packages 1 and 3 package contain a particulate detergent composition 5, wherein the composition 5 comprises any of the above examples.
  • the sachet comprises a compressible reservoir structure 11 for containing the composition 5.
  • the reservoir is compressible by means of a flexible plastic sheet material together with the side gusseting 13, so as to be compressible to a substantially flat structure (not shown).
  • the bottle 1 comprises a rigid reservoir 17 and narrow aperture 19 (shown more clearly in Figure 2 ).
  • a narrow aperture would not normally be desirable in a refillable package for conventional laundry compositions.
  • the reliable and predictable flow of the particulate composition via a narrow dispensing aperture allows for dispensing of the composition into a narrow aperture. This in turn prevents the ingress of large amounts of moisture which might affect the particulate composition.
  • the narrow refilling aperture approximately 4 cm in diameter. Circular shaped apertures allow filling from any angle and are advantageous. Alternatively or additionally apertures with corners locating means for supporting the refill package in position during loading.
  • the refillable container is a totally transparent PET bottle.
  • Other embodiments not shown incorporate labels to bear information, graphics but the visual appeal of the transparency and the particles means expensive graphics are not as necessary as with conventional laundry particulate products. Even if labels are incorporated, preferably the transparency extends to the base and covers at least 60%.
  • the bottle 1 is resealable with a closure mechanism, to avoid the flow properties being affected by ingress of large amounts of moisture, which could lead to stickiness.
  • the closure mechanism comprises a screw-fit mechanism or a snap-fit mechanism. It comprises audible feedback to signal positively to the consumer that the package is closed.
  • the refillable package is resealable by zip or other means.
  • the sachet also comprises a transparent portion, being window 7.
  • Transparency combined with the size (no fines), colour, and homogenity of the composition provides a striking visual impact for the compact package.
  • "transparent" means that its light transmittance is greater than 25% at wavelength of about 410-800 nm.
  • 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).
  • absorbency of transparent layer may be measured as less than 0.6 (approximately equivalent to 25% transmitting) or by having transmittance greater than 25% wherein % transmittance equals: 1 10 absorbency ⁇ 100 %
  • absorbency of the opaque layer may be measured as more than 0.6.
  • the container is considered to be transparent.
  • absorbency of bottle may be measured as less than 0.6 (approximately equivalent to 25% transmitting) or by having transmittance greater than 25% wherein % transmittance equals: 1 10 absorbency x 100% and corresponding absorbency levels for the remaining preferred levels above.
  • Suitable materials for 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.
  • Both package types embodied here are rigid such that the base 21 can be tapped to move the particles throughout the reservoir.
  • a major portion by number of the particles are coloured blue other than white, which increases visual appeal as well as making them easier to see to determine that the required dose level has been reached in any dosing devices (caps, shuttles etc).
