Definitions

  • the invention relates to single-dose articles which are suitable for treating fabrics in a washing machine, and which contain a fabric-treatment composition such as a detergent composition.
  • these devices improve dosage control and considerably reduce loss of detergent composition caused by retention in the dispensers of washing machines.
  • the empty sachets are flat or in the form of sheets, so that they offer even less grip than in the initial form; moreover, the sachets are wet and often stick to the drum of the washing machine, which makes them uneasy to locate and grip.
  • the present invention provides single-dose fabric treatment products, in the form of sachets, which are easy to manipulate both before and after the wash cycle.
  • the present invention provides sachets containing a fabric-treatment product which are equipped with a permanent handling device.
  • the sachets of the present invention are preferably rectangular, and formed either from two rectangular sheets of flexible material bonded together at their four edges, or from a single sheet of flexible material folded over and with the remaining three edges bonded together.
  • the sachets of the present invention are characterized in that a handling device is permanently attached to the sachet.
  • the handling device consists of a rigid or a semi rigid component of such a shape so as to allow it to be gripped easily.
  • the rigid or semi rigid material is selected from polyethylene or polypropylene.
  • the handling device may be a full or hollow moulded component, but in a preferred embodiment, it consists in a loop formed by a rigid or semi rigid material; Preferably, such loop has a triangular cross section.
  • the handling device consists of a hollow, moulded component, it will preferably have a ring or doughnut shape.
  • the handling device may consist of a component directly attached to the sachet; in such case, any adhesive compound can be used but preferably, the component will be attached using an ultrasonic welding technique.
  • the component has a ring or doughnut shape
  • the handling device contains a rigid or semi-rigid component indirectly attached to the sachet; in such a case it is necessary to provide a means to attach the rigid or semi rigid component to the sachet.
  • such means consist in a thread made of rigid or flexible material, and the rigid or semi-rigid component is of a shape such as to be held easily in the hand; for instance, a spherical shape is appropriate.
  • the handling device has several different possible locations on the sachet : In one embodiment of the invention, the handling device is attached to one edge of the sachet, but in a preferred embodiment, the handling device is attached to an integral fin extending outward from one of the edges of the sachet or to an integral fin extending outward from one surface of the sachet.
  • the handling device according to the invention may be colored, printed or embossed by any means such as to make them easy to locate and/or identify by a logo or a brand name.
  • the present sachets can be non-opening, in which case, the sheet material is such as to allow water to pass through and dissolve the detergent composition, which is then released.
  • said sachets contain at least one opening side, i.e. a side which, while being closed by closing means before use of the sachet, opens up when in use in a washing machine, and allows dispensing of the fabric-treatment composition contained in it.
  • sachets which are formed of a single sheet of flexible material folded over, and with the three remaining edges being opening sides, such as defined above. After the wash cycle, such sachets are in the form of a sheet.
  • the closing means of the opening sides contain preferably water-soluble seals, although mechanically-weak seals or combinations of water-soluble and mechanically-weak seals can be used.
  • Suitable water-soluble adhesives can, for example, be based on polysaccharides such as starch or dextrin, synthetic polymers such as polyvinyl alcohol, or alkali metal silicates or polyethylene oxide. Small amounts of plasticizers, for example ethylene glycol, can be added to the water-soluble adhesives, if desired.
  • the flexible sheet materials which are used to form the sachets herein can be made of paper, of woven, knitted or non-woven fabrics, or of plastic film material.
  • the materials should be water-insoluble and can be either water-permeable or water-impermeable.
  • the materials used to form the sachets are required to have a high wet strength, so as not to disintegrate during the washing process.
  • the preferred sheet material for forming the bags is paper or thin non-woven fabric made out of synthetic fibres; synthetic fibres include fibres made out the following materials : Polyethylene, polypropylene, polyester, polyamide, polyacrylate, cellulose acetate, polyacryloritrile, and any mixture thereof.
  • cellulosic materials can be used to make the non-woven fabrics herein, alone or in admixture with either synthetic or natural fibres. If natural fibres are used, it is desirable to include a proportion of long fibers such as manilla hemp, in order to improve the strength of the sheet material, and polymeric coating is also desirable for increasing wet strength.
  • thermoplastic materials including perforated materials such materials may advantageously be selected from polyolefins such as polyethylene, polypropylene, polystyrene; polyesters especially polyethylene terephthalate; vinyl polymers such as insoluble polyvinyl acetate and polyvinyl acrylate, polyvinyl chloride, and polyvinylidene chloride; polyamides and polyacrylonitrile; and other thermoplastic sheet materials having similar physical properties.
  • polyolefins such as polyethylene, polypropylene, polystyrene
  • vinyl polymers such as insoluble polyvinyl acetate and polyvinyl acrylate, polyvinyl chloride, and polyvinylidene chloride
  • polyamides and polyacrylonitrile and other thermoplastic sheet materials having similar physical properties.
  • the fabric-treatment compositions which are contained in the sachets of the present invention are in particulate form, and are usually detergent compositions, i.e., a composition containing at least a surfactant and a builder is suitable for use in the present context; as an alternative, the sachets of the present invention can contain any particulate ingredient which is active during the wash and rinse cycles : bleaches, bleach activators, fabric softeners, perfumes, whitening or brightening agents, stain removal agents, enzymes and the like. It can be appropriate to keep certain of these ingredients separate during storage, and therefore executions of the present invention can be conceived, wherein the present sachets contain at least two separate compartments;
  • each of these sachets is detachable from the others and each sachet has an individual handling device according to the invention.
  • the sachets contain the following particulate detergent composition. Ingredients Percent by weight Anionic surfactant 8.0% Nonionic surfactant 5.0% Sodium tripolyphosphate 24.5% Sodium perborate monohydrate 14.0% Bleach activator 4.0% Enzyme 0.8% Sodium silicate 8.0% Sodium carborate 11.0% Minors and water balance to 100
  • Fig. 1A represents the sachet before use
  • Fig. 1B represents the sachet during the wash cycle.
  • the sachets consist of a sheet 1 of polyethylene oxide which is folded in two unequal parts; the three remaining edges 2a, 2b, 2c are bounded together, using a water soluble adhesive such as high molecular weight polyethylene oxide; these seals are represented by the hachured regions in Fig. 1A.
  • a fin 3 extends outward from the seal 2c and the handling device 4 is fixed on said fin; the hanling device consists of a loop of polypropyene, such loop has a triangular cross section and is 15 mm long.
  • This example refers to Fig. 2A and 2B which represent, respectivly, the sachet before and during the wash.
  • This sachet consists of a sheet 1 which is folded three times, as illustrated in Fig. 2B.
  • the three edges 2a, 2b and 2c are bonded, using high molecular weight polyethylene oxide as a water soluble adhesive; the three seals are represented by the hachured regions in Fig. 2A.
  • This sachet has a fin 3 extending outwards from the middle seal in 2c and a handling device 4 is attached to said fin.
  • FIG. 3A and 3B represent, respectivly, the sachet before and during the wash.
  • This sachet consists of a sheet 1 which is folded three times, as illustrated in Fig. 3B.
  • the three edges 2a, 2b and 2c are bonded, using high molecular weight polyethylene oxide as a water soluble adhesive; the three seals are represented by the hachured regions in Fig. 3A.
  • the sachet has a handling device 4 which is fixed at one extremity of one of the lateral seals 2a or 2b.
  • the sachet After having discharged the fabric treatment composition, the sachet is in the form of a sheet, but remains folded, since the handling device is positioned on a seal and, therefore, holds together a portion of the two edges.
