Definitions

  • This invention relates to water soluble detergent sachets comprising a detergent composition, in particular a laundry detergent or machine dishwashing composition.
  • detergent compositions especially laundry detergent compositions
  • the consumer is required to determine and provide the correct dosage of the product at the point of use. This may lead to over dosing of the product and/or to an increased risk of spillage or wastage.
  • detergent products have been commercially available in a form which provide a single dose of the detergent product for the consumer to add directly to the cleaning operation.
  • Two examples of these single-dose products are laundry detergent tablets of compressed powder and water-soluble sachets of detergent composition which may contain the detergent product in liquid, paste or particulate form.
  • Water-soluble sachets generally comprise a detergent composition encapsulated with water-soluble film, such as polyvinyl alcohol. Encapsulation allows for handling of the product without direct contact with the detergent composition. This is especially advantageous when the detergent composition comprises aggressive cleaning components which could irritate the skin on direct contact.
  • This invention relates to water-soluble sachets a detergent composition wherein the sachets comprise from 2 to 5 compartments.
  • WO 01/85898 describes a multi-compartment pouch obtained by closing an open compartment with a pre-sealed second compartment.
  • the process as proposed requires a complicated process and may incur the risk that the pre-sealed compartment is damaged during the handling and secondary sealing.
  • WO 02/8380 describes a multicompartment pouch in pouch product wherein one ore more of the pouches may comprise a liquid detergent product.
  • W0 02/42408 descibes multicompartment pouches for dishwashing products wherein the compartments are superposed.
  • Another potential problem due to interaction e.g. due to moisture migration between ingredients in the different compartments is that some ingredients e.g. bleach (activators), colorants, enzymes etc. may decompose.
  • the present invention aims at providing alternative multi-compartment pouches of water-soluble material which have a reduced tendency of water migration between the compartments and which accordingly have a reduced tendency of weakening or damaging the partition between compartments and/or which have an increased stability of the detergent ingredients in the compartments.
  • the invention relates to a multi-compartment package comprising from 2 to 5 compartments of water-soluble material, said package containing at least two different cleaning compositions and wherein said compartments are connected to each other and seperated by at least one flat seal area having a width of from 1 to 10 mm.
  • multicompartment packages of the invention can be made by any suitable process it is especially preferred to produce the multi-compartment packages by a process of thermoforming.
  • Sealing can be done by any suitable method for example heat-sealing, solvent sealing or UV sealing. Particularly preferred is water-sealing.
  • the present invention providing multi-compartment pouches of water-soluble material containing at least two different cleaning compositions which have a reduced tendency of water migration between the compartments and which accordingly have a reduced tendency of weakening of damaging of the partition between compartments.
  • the compartments are separated by a seal with a width of from 1 to 10 mm, more preferred 2 to 9 mm, most preferred 3 to 7 mm.
  • each compartment will have a top surface area adjacent to the seal area of from 0.5 to 50 cm 2 , more preferred from 1 to 40 cm 2 , most preferred from 1.5 to 35 cm 2 .
  • each compartment can have various shapes composed of curved or straight lines or combinations thereof for example triangle, hexagonal, round, square, ellustl, rectangular. Preferred are rectangular, square or round forms.
  • the perimeter of the entire multi-compartment package can have any form.
  • a rectangular form but other forms may equally be applied for example various shapes composed of curved or straight lines or combinations thereof for example triangle, hexagonal, round, square or elappell.
  • each compartment has a maximum depth of from 1 to 40 mm, more preferred from 2 to 35 mm, most preferred from 5 to 30 mm.
  • the sides of the compartments are relatively steep e.g. the angle between the top surface area of the package and the sides of the package can advantageously be from 90 to 30 degrees, more preferably from 90 to 45 degrees, most preferred from 90 to 60 degrees.
  • the release time of product from each compartment can be adapted by changing the steepness of the sides of the pack and or the curvature between the sides and the bottom of the pack.
  • a compartment made in cavity with a continuously curved side/bottom area which only involves rounded corners (for example with an internal radius of more than 20 mm, for example from 30 to 100, more preferred from 40 to 80 mm will have a more even film thickness distribution and will therefore release its contents relatively slower than a compartment with more steep and square sides.
  • a compartment with relatively steep and square sides is characterised by a relatively small internal radius of curvature in the corner, said radius being from 0 to 20 mm, more preferred from 1 to 15 mm, most preferred from 3 to 10 mm.
  • a preferred embodiment of the invention relates to multi-packs composed of compartments of different size and/or different depth.
  • the ratio of top surface areas of the largest and the smallest compartment may be from 20 : 1 to 1 : 1, most preferred from 10 : 1 to 1.2 : 1, most preferred from 5 : 1 to 1. 3: 1.
  • the ratio of the depth of the deepest compartment and the least deepest compartment may be from 10 : 1 to 1 : 1, more preferred 5 : 1 to 1.1: 1, most preferred from 3 :1 to 1.3 : 1.
  • compartments are shaped in such manner that the average film-thickness in one of the compartments differs from the average film-thickness in one of the other compartments.
  • one of the compartment may have an average film thickness which is at least 10 %, more preferred at least 20 %, most preferred at least 25 % more than the film thickness of the compartment with the least average film thickness.
  • the average film thickness can be determined by the following methods:
  • Suitable methods to reduce the average film thickness generally stem from a high ratio of the top-surface area of the recess to the total internal surface of the recess.
  • a high ratio of the top-surface area of the recess to the total internal surface of the recess For example for a square recess having a top surface area of p * p and a depth d resulting in an internal surface area of (p * p + 4p * d).
  • the ratio of internal surface area to top surface area is defined as the stretch factor.
  • each recess has a stretch factor of from 1.2 to 20, more preferred from 1.5 to 15, most preferred from 2 to 12.
  • the ratio of the highest stretch factor to the lowest stretch factor is from 1.0 to 5.0, more preferred from 1.1 to 4.5, most preferred from 1.2 to 4.0.
  • the difference in stretch factor leading to a difference in average film thickness between the various compartments can be used to manipulate the release times of the ingredients in the different compartment.
  • a compartment with a high stretch factor could be used to effect fast release of components, for example most of the builder material -which is advantageously released fast- is contained in a compartment with a relatively high stretch factor, whereas a compartment with low stretch factor could be used to release ingredients in a more delayed fashion (e.g. advantageously perfume or softener ingredients). It will be understood that by changing the stretch factor per compartment a wide flexibility can be obtained to tailor the release profile of the various ingredients.
  • the film thickness to form the recessed compartments is from 30 to 150 micrometer, more preferred from 40 to to 100 micrometer, most preferred from 60 to 90 micrometer. After stretching generally the average thickness will be from 10 to 150 micrometer, more preferred from 20 to 100 micrometer, most preferred from 30 to 80 micrometer. It will be appreciated that the film thickness used for preparing the recessed compartments -especially if they have a relatively high stretch factor- may advantageously be higher than the film thickness used for preparing the top surface area. In an advantageous embodiment of the invention the ratio of thickness of the first film to the thickness of the second film is therefore from 1 : 1 to 2 :1. Typical advantageous thicknesses for the top film may be from 20 to 100 micrometer, more preferred from 25 to 80 micrometer, most preferred from 30 to 60 micrometer.
