Definitions

  • the present invention relates to a multi-compartment pouch with one or more inner compartments surrounded by one or more outer compartments, a method for making such a multi-compartment pouch as well as to the use of said pouch in methods for washing or cleaning an article or a surface.
  • Detergent and cleaning products are commercially available in various different forms, including for example tablets as well as powdery, granular, pasty, gel-like and liquid compositions.
  • unit-packaged detergent compositions have become increasingly popular due to the convenience of dosing them and the improved safety for the user as the risk of unintended contact with said compositions is diminished.
  • a water-disintegrable packing e.g. a water-soluble foil, any unintended contact with the composition may be completely avoided, as during manual handling the composition is protected by said packing which will only disintegrate upon contact with water, e.g. inside the dosing chamber of a laundry or a dishwashing machine.
  • the packing comprises several compartments, it is even possible to simultaneously dose two different compounds or compositions at the same time in one single step, which otherwise are not compatible with each other during storage.
  • Using a multi-compartment packing wherein each compartment is packed in different packing material it is also possible to provide pouches that sequentially release the contents of the individual compartments.
  • a further drawback of multi-compartment pouches wherein the compartments are arranged solely in an adjacent manner is the fact, that compartments comprising a liquid content are always in risk of being damaged or even bursting during handling or under mechanical impact, thus leaking their liquid content.
  • the same drawback is found in multi-compartment pouches wherein a liquid-containing compartment is located on the outside of said pouch above another compartment. The same is true for hygroscopic contents.
  • WO 02/42408 A2 discloses water-soluble containers of essentially rectangular outer shape comprising a plurality of internal partitioning walls to separate the different compartments from one another. Said containers are made by thermoforming or vacuum-forming. Even though these pouches provide a good mechanical stability even for liquid contents if said liquid contents are filled into an inner compartment, the process of making these pouches by thermoforming or vacuum-forming is rather expensive. Also US 2005/00033982 A1 describes compartment detergent pouches having walls composed of a water-soluble or dispersible water-containing polymer film made by vacuum-forming.
  • the present invention provides a multi-compartment pouch according to claim 4 comprising one or more inner compartment(s) and one or more outer compartment(s), the latter surround(s) at least 75 % of the outer surface of said inner compartment(s).
  • Water-sensitive and/or liquid compounds or components preferably may be filled into said inner compartment(s) and thus are protected from environmental humidity and/or mechanical impact by both the additional water-disintegrable film or foil surrounding the outer compartment(s) as well as the content of said outer compartment(s).
  • an inner compartment comprising liquid content is damaged, for example due to mechanical impact, said content leaks into said outer compartment, there being absorbed by the preferably solid content of said outer compartment.
  • the whole multi-compartment pouch maybe formed from rather thin water-disintegrable film or foils, e.g. having a thickness of less than 1 mm, for example in form of a sachet.
  • the pouches of the present invention preferably represent a sachet and not a rectangular container, made by moulding, thermoforming or vacuum-forming.
  • the present invention provides a method for making a multi-compartment pouch comprising one or more inner compartments and one or more outer compartments, the latter surrounding at least 75 % of the outer surface of said inner compartment(s), each compartment being completely surrounded by at least one water-disintegrable film or foil, comprising the steps of: (i) providing an assembly of essentially tubular shape comprising at least one inner tube, which optionally may already be filled with at least one detergent or cleaning adjuvant, and at least one outer tube, the latter surrounding at least 75 % of the outer surface of said inner tube(s), by forming said tubes from at least one water-disintegrable film or foil having a set of opposed lateral edges and sealing said lateral edges either to each other or another part of the lateral surface of said tube (vertical seal) to fix said tubes, (ii) filling in at least one of the inner and/or the outer tubes a portion of detergent and/or cleaning adjuvant, (iv) introducing at least one seal below and/or above said portion of detergent and/or
  • Said outer compartment(s) preferably surround(s) at least 80 % of the outer surface of the said inner compartment(s), more preferably at least 85 %, even more preferably at least 90 %, particularly preferably at least 95 % and most preferably essentially the whole outer surface of said inner compartment(s) (except for the small part of the surface at which the horizontal seals are located).
  • a film or foil is water-disintegrable if it dissolves, disperses, melts or ruptures upon contact with water or an aqueous solution.
  • the water-disintegrable film or foil used for making the multi-compartment pouch of the present invention does not leave more than 20 wt.-%, even more preferably not more 10 wt.-% and most preferably less than 5 wt.-% of solid residue when 10 grams of said material are placed in a vessel, completely covered with 100 mL of water having a temperature of max. 50Ā°C, preferably of max. 40Ā°C, more preferably of max.
  • a cold water-soluble film or foil i.e. a film or foil which disintegrates at a temperature of 25 Ā°C or below under conditions described above, to cover the outer surface of the outer compartments, i.e. to form the outer tube(s) of the assembly of essentially tubular shape used in the method of the present invention, while a film substantially insoluble in water having a temperature of 25Ā°C or below, but being soluble in water having a temperature of 40 Ā°C or above maybe used for surrounding one or more of the inner compartments, i.e. for forming one or more of the inner tube(s). In this way, retarded release of the content of said inner compartments may be achieved.
  • the velocity of disintegration may also be controlled by the thickness of the film or foil.
  • the thickness of the film or foil used is in the range of from 10 ā‡ m to 100 ā‡ m, both for the thickness of the film before it is formed into an essentially tubular shape as well for the thickness of the films or foils in the multi-compartment pouch, i.e. after having been formed into tubular shape.
  • films or foils of different disintegration behavior in water may be either made of a different basic film or foil material, i.e. comprise different polymers, or they may be made of the same basic foil material, wherein a part of said foil material is treated on its surface by physical or chemical means to control the disintegration behavior.
  • the multi-compartment pouches of the present invention represent a sachet, i.e. usually they more or less have a pillow shape having at least two flat outer edges formed by horizontal top and bottom seals, whereas the middle part of the sachet lying between said flat edges is extended in volume due to the filling of the compartment(s).
  • the assembly of essentially tubular shape preferably is formed from at least one continuous flat roll or sheet of the aforementioned films or foils using the VFFS technique by flapping said film or foil around a preferably hollow forming tube, more preferably an essentially conical hollow forming tube and vertically sealing said edges either to each other or to another part of the lateral surface of said tube to fix the tubular shape of the foil.
  • a vertical form-film-seal machine is used which is continuously operated.
  • the film or foil From a continuous roll the film or foil approaches the back of the hollow forming tube and is formed around said forming tube into an essentially tubular shape for example by forming collars. The film or foil is then guided downwards along said forming tube, for example by low friction rollers and vertically sealed, for example by heat-sealing bar clamps on its edges. If the vertical form-fill-seal technique is used it is preferred to introduce one horizontal seal before starting filling of the film tube to create an open bag which then may be filled with substances dispensed through the hollow forming tube into the center of the bag. When filling is completed, the bag, i.e. the compartment in terms of the present invention, may be closed by introducing a further horizontal seal above the filled-in material.
  • Another advantage of the present invention is that for forming a multi-compartment pouch of the present invention no thermoforming, vacuum-forming or filling on a rotary drum as described for example in US 3,057,127 is needed. Hence the use of all of these methods preferably is excluded in the process of making the multi-compartment pouch of the present invention.
  • VFFS-technique A further advantage of the VFFS-technique is the fact that the compartments usually are not completely filled and thus remain more flexible and deformable than a pouch which is completely filled. This higher flexibility and deformability ensures that the multi-compartment pouches of the present invention can be easily fit into dosing chambers of different shape.
  • the remaining space in the compartments above the filling with detergent and/or cleaning adjuvant may be filled with a gas or a mixture of gases, including for example air, nitrogen, noble gases and the like, without being limited to them, either at atmospheric, positive or negative pressure.
  • the gas or the mixture of gases may be inert towards the contents of the compartment, but it may as well be suitable to trigger a chemical reaction with the composition or one or more of its ingredients. If a gas or a mixture of gases is filled into at least one compartment, preferably said gas or gas mixture does not leak out of the multi-compartment pouch, neither through the seals nor through the foil itself.
  • the sealing in the machine direction i.e. the direction in which the foil material is moved during making of the tube(s) in a traditional VFFS machine, is called the vertical seal due to its vertical position in said traditional VFFS machine.
  • a folded strip of film or foil may be closed to fix a tubular shape and/or the vertical seal may divide a preformed tube into two compartment tubes.
  • the vertical seal may be a rim protruding from the outer surface or the inner surface of the tube or the vertical seal may be an integrated part of the outer wall of the tube or an inner sidewall which divides the tubes into two compartments.
  • a tube already fixed by a vertical seal may be further divided into three compartments by adding two additional vertical seals.
  • Each of said vertical seals may be independently form an angle of from above 0 to 90Ā° with one or more horizontal seals, including 10, 15, 30, 45, 60, 75, 80 and 85Ā°.
  • Each vertical seal may be arranged to another vertical seal to include an angle in the range of from 0 to 90Ā°, including 5, 10, 15, 30, 45, 60, 75, 80 and 85Ā°.
  • a horizontal seal closes the bottom side of a tube to create an open chamber (or a plurality of open chambers if the tube had previously been divided into more than one tube by adding additional vertical seals).
  • the compartments are closed by introducing a further horizontal seal at the top, i.e. above the filling level of said compartments.
  • Said top seal may simultaneously create a further open chamber (or plurality of further open chambers) above the filled and closed compartment, i.e.
  • a bottom seal can be introduced as well when introducing a top horizontal seal. This may be used to create a further compartment inside the same pouch or the horizontal seal may be divided for instance by cutting to produce one multi-compartment pouch and start a new open chamber for a further multi-compartment pouch.
  • Each horizontal seal may be arranged to another horizontal seal to include an angle in the range of from 0 to 90Ā°, including 5, 10, 15, 30, 45, 60, 75, 80 and 85Ā°.
  • the method of the present invention preferably may comprise the steps of iii) filling at least one gas into at least one of the compartments before horizontally sealing it, and/or v) removing the sealed pouch from the remaining film or foil.
  • Removing the sealed pouch from the remaining film or foil may for example be achieved by cutting through a horizontal seal forming the bottom seal of one pouch and the top seal of a further pouch.
  • the multi-compartment pouch comprises one or more inner compartment(s) and one or more outer compartment(s), the latter surrounding at least 75 % of the outer surface of said inner compartment(s), the compartments being filled with detergents or cleaning adjuvants wherein each compartment is completely surrounded by at least one layer of at least one water-disintegrable film or foil and wherein the number of vertical seals per number of compartments in the pouch is above 0 but below 2.
  • the compartments inside said multi-compartment pouch preferably are essentially fixed in their relative position to each other at least by the horizontal top and bottom seals of the pouch.
  • the pouch of the present invention preferably does not comprise any freely movable inner compartments inside the outer compartments.
  • the number of vertical seals necessary to form and seal compartments is reduced in comparison to conventional methods of forming multi-compartment sachets by introducing a preformed sachet into a further sachet, as described for example in EP 0 132 726 A2 . This further reduces the efforts with respect to time and costs in the production process.
  • At least one and more preferably all of the compartments in the pouch of the present invention are filled with a compound or a composition independently selected from the group comprising detergents, cleaning adjuvants and mixtures thereof, even more preferably independently selected from the group comprising dish-washing detergents, laundry detergents, machine cleaning and maintenance detergents, components of the aforementioned detergents, water softening compounds or compositions, lime-scale-preventing compounds or compositions, rinse-aid compounds or compositions or mixtures thereof, wherein most preferably each compartment comprises a different compound or composition.
  • a compound or a composition independently selected from the group comprising detergents, cleaning adjuvants and mixtures thereof, even more preferably independently selected from the group comprising dish-washing detergents, laundry detergents, machine cleaning and maintenance detergents, components of the aforementioned detergents, water softening compounds or compositions, lime-scale-preventing compounds or compositions, rinse-aid compounds or compositions or mixtures thereof, wherein most preferably each compartment comprises a different compound or composition.
  • detergent includes both fully formulated and ready to use detergent composition as well as components thereof, including for example anionic, cationic, nonionic and amphoteric surfactants, soaps, builders, enzymes, polymers, bleaching agents, bleach activators, bleach catalysts, optical brighteners, sud suppressors, dispersants, anti-redeposition agents, soil release agents, metal ion sequestrants, corrosion inhibitors, crystal growth inhibitors, colorants, dyes, perfumes, organic solvents, and the like as well as mixtures thereof without being limited to these.

  • the pouch of the present invention is a multi-compartment pouch, it is possible to provide a fully formulated detergent composition wherein interfering compounds may be separated during transport and storing and are mixed only upon the start of the washing cycle. It may for example be preferable to separate compounds having bleaching activity from enzyme composition by filling them into different compartments. As well e.g. combinations of for example detergents and rinse aids or detergents and lime scale preventing compositions are possible.
  • the compounds or compositions filled into each compartment independently may represent a solid, including powders, granules, crystals, pellets, beads, compressed solids, blocks, a paste, a cream, a wax, a gel, a liquid, a gas or a mixture thereof.
