Definitions

  • This invention relates to a dispenser for use inside an automatic dishwasher to provide controlled release of dishwashing active ingredients into the dishwasher over multiple dishwashing cycles.
  • EP 154421 describes a solid product formed from polyethylene glycol and nonionic surfactants which provides controlled release in the wash and rinse cycles for improved cleaning and reduced spotting and streaking.
  • the product is placed inside a cylindrical dispenser having a top opening of 20 sq.cm in area and four side openings whose sizes can be adjustable according to water temperature and which range from 0.6 to 2.5 sq.cm in area.
  • W096/38638 describes a dispenser for dispensing fragrance in the form of a waxy cake into a dishwasher during operation.
  • the dispenser has a main body portion forming a cavity into which the waxy cake is secured by means of retaining pins, and a hinged lockable front plate having elongated openings through which water can pass to dissolve and release fragrance.
  • the openings are large enough to provide a visual indication of the amount of fragrance cake remaining in the dispenser.
  • a problem with dispensers such as those described above is their high unit cost and complexity to manufacture on a large scale, due to their multi-part construction and the requirement for injection moulding techniques.
  • the present invention provides a solution to the problem of obtaining effective controlled release of dishwashing active ingredients into the interior of a dishwasher in a low cost and adaptable manner.
  • a dispenser according to the preamble of the independent claim is known from EP 1 072 715 .
  • a dispenser for use inside an automatic dishwasher to provide controlled release of one or more dishwashing active ingredients into the dishwasher over multiple dishwashing cycles, the dispenser comprising a perforated flexible polyolefin sheet which is in fluid communication with a composition having one or more dishwashing active ingredients, in which the perforation density of the polyolefin sheet ranges from 1 to 100 perforations per cm 2 of sheet and in which the perforations individually have an area ranging from 0.0004 to 0.01 mm 2 .
  • multiple dishwashing cycles is meant at least two dishwashing cycles, and may conveniently be up to about 100 dishwashing cycles. Conveniently the controlled release may occur over a period of 2 to 60, preferably 30 to 60, dishwashing cycles.
  • dishwashing cycle in this instance is meant a complete dishwashing cycle, including any pre wash, a wash at normal temperature (e.g. 50°C), and any rinses.
  • a method of providing controlled release of one or more dishwashing active ingredients into the dishwasher over multiple dishwashing cycles comprising the steps of packaging a composition containing the one or more active ingredients into a dispenser as defined above, adding the dispenser to a dishwasher prior to the commencement of a dishwashing cycle, and leaving it in the dishwasher for multiple dishwashing cycles.
  • the dispenser is in the form of a sachet comprised of two side walls sealed around the peripheral edges and enclosing the composition as defined above, in which at least one (but conveniently both) of the side walls comprises a perforated flexible polyolefin sheet as defined above.
  • a sachet is simple and cost-effective to produce. It also enables improved tailoring and adaptability of dosage and ingredients, since the low unit cost means that such sachets can be used in multiples. In this way, the user can boost the dosage of a particular dishwashing active ingredient as and when required, or can provide a regime of different dishwashing active ingredients in individual sachets according to requirements.
  • the packaging of different dishwashing active ingredients into separate individual sachets according to the invention also solves the problem of product stability in those instances where such ingredients may be chemically and/or physically incompatible (for example where oxidative materials such as bleaches are involved together with other oxidation-sensitive materials).
  • Suitable flexible polyolefin materials used to form the perforated flexible polyolefin sheet in the dispenser of the invention will retain their integrity at the temperatures involved in dishwashing (e.g. 70 to 75degC) for prolonged periods.
  • Examples include low density polyethylene, polypropylene, and high density polyethylene.
  • the flexible polyolefin sheet can also be a laminate.
  • the perforations of the flexible polyolefin sheet have individual areas ranging from 0.0007 mm 2 to 0.006 mm 2 , and a perforation density of from 1 to 10 perforations per cm 2 of sheet.
  • the perforations are circular.
  • the perforated flexible polyolefin sheet of the dispenser may be coated with a water soluble polymer such as polyvinyl alcohol to prevent egress of the contents of the dispenser prior to use.
  • a water soluble polymer such as polyvinyl alcohol
  • a device for use in a dishwasher may comprise a number (e.g. 1 to 5, preferably 2 to 5) of dispensers according to the invention retained in the device, with each dispenser containing different dishwashing active ingredients intended for use in the dishwashing cycle.
  • One or more of the dispensers may be interchangeable in the device for a fresh dispenser, thereby enabling the device to be used for more than the lifetime of the individual dispensers.
  • multiple dispensers containing the same dishwashing active ingredient can be used in such a device, so that the user can tailor the number used and hence the dosage provided into the dishwasher according to the prevailing conditions (such as water hardness or level of soiling).
  • Dispensers according to the invention contain one or more dishwashing active ingredients.
  • dishwashing active ingredient is meant an ingredient that enhances the end-results obtained after treatment of articles in the dishwasher. Such enhancement may occur by improved removal of soil, reduction of deposits such as films, spots or streaks left on the articles after they have been treated in the dishwasher, or reduction of negative effects associated with the dishwashing process such as glass corrosion and colour fading.
  • Suitable dishwashing active ingredients include rinse-aids, anti-scaling agents, bleaches and bleach activators, builders, chelating agents, degreasing agents, anti-spotting agents and glass anti-corrosion agents (such as those described in WO00/39259 and WO01/64823 ).
  • dishwashing active ingredients in the context of this invention are nonionic surfactants. These provide a rinse-aid functionality in the dishwasher, and may be used alone or in combination with other dishwashing active ingredients.
  • the dishwashing active ingredient contains nonionic surfactant
  • the nonionic surfactant is selected or prepared to have the desired leaching rate through the perforated flexible polyolefin sheet of the dispenser. This may be achieved by a number of technical routes.
  • the nonionic surfactant is selected so as to be one which forms a thickened liquid crystal phase, such as a meso-phase on the addition of water.
  • a meso-phase is a form of liquid crystal which can be formed by the addition of water to some nonionic surfactants, which liquid crystal form is relatively insoluble. It is this relative insolubility and the consequent leaching properties which make the selected nonionic surfactants particularly suitable for use in the dispenser of the invention.
  • Suitable nonionic surfactants which provide such a relatively insoluble meso-phase on the addition of water include ethoxylated surfactants, ethylene oxide/propylene oxide block copolymer surfactants, and blends of these with ethoxylated surfactants.
  • the nonionic surfactant is selected so as to be one which is a solid at room temperature, which dissolves slowly in water, and which typically has a cloud point in the range 12°C to 30°C.
  • the cloud point may be less than 25°C, more preferably less than 20°C, and in some embodiments may preferably be less than 15°C.
  • a suitable example of a nonionic surfactant having the above properties is POLYTERGENT SLF18B45, ex BASF.
  • the nonionic surfactant can be prepared so as to have a suitable leaching rate in the dispenser of the invention.
  • One way is to impregnate the nonionic surfactant onto an insoluble, preferably flexible textile substrate.
  • the textile substrate may be woven or non-woven. Suitable textile substrates include cotton. However, other suitable substrates are inflexible hard solids, and include porous inorganic insoluble materials such as zeolites, silica, phosphates and carbonates, as well as clays.
  • a further method of preparing a nonionic surfactant so as to have a suitable leaching rate includes combining it with a suitable thickener or structurant, to provide a gel.

It is preferable if the level of anti-scaling agent is from 0.2 to 95%, preferably from 0.5 to 50% by total weight of anti-scaling agent based on the total weight of the composition in the dispenser.
  • Suitable anti-scaling agents include water soluble polymers which reduce phosphate scale formation.
  • Such a polymer often comprises at least one structural unit derived from a monomer having the formula: wherein R 3 is a group comprising at least one sp 2 bond, z is O, N, P, S, or an amido or ester link, A is a mono- or a polycyclic aromatic group or an aliphatic group and each p is independently 0 or 1 and B + is a monovalent cation.
