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 provides 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 00/55045, WO 00/55046, WO 00/55068, WO 00/55069, WO 00/55415 and WO 01/83668 describe processes for the preparation of water-soluble detergent capsules or pouches by thermoforming.
  • the present invention aims at providing alternative multi-compartment pouches of water-soluble material, which can be easily prepared at low costs.
  • the invention relates to a process for the producing a water-soluble multi-compartment package comprising two to five closed compartments, said package containing at least two different cleaning compositions, comprising the steps of:
  • 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 provides a multi-compartment package comprising from 2 to 5 compartments obtained by thermoforming a water-soluble film, said package containing at least two different cleaning compositions and wherein said compartments are connected to each other and separated by at least one seal area.
  • the present invention providing multi-compartment pouches of water-soluble material containing at least two different cleaning compositions, which can be easily prepared at low costs.
  • the invention involves the specific use of a thermoform process whereby two or more recesses are formed. Two to five adjacent recesses will form the multi-compartment package of the invention. Subsequent to thermoforming, the recesses are filled with cleaning compositions. At least two different cleaning compositions will be used; whereby each of said different cleaning compositions is present in a separate compartment of the multi-compartment package. After dosing the cleaning compositions the compartments will be sealed. Subsequently the packages will be cut to detach from the remaining of the film and from the other multi-compartment packages. The cutting will be carried out such that the two to five compartments of the package will remain connected to each other while being separated by a seal area.
  • a suitable device for carrying out the method of the invention may comprise a moulding plate comprises a plurality of recesses, said recesses being divided in groups of 2-5 each group of recesses is separated by distance b (not shown), which is preferably at least 10 mm, more preferred from 10 to 25 mm, most preferred from 11 to 15 mm.

  • each recess 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.
  • Figure 1 illustrates a rectangular or circular 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 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.

  • 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 is 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.

After stretching generally the average thickness will be from 10 to 150 micrometers, more preferred from 20 to 100 micrometers, most preferred from 30 to 80 micrometers.
  • 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.
  • 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 thickness for the top film may be from 20 to 100 micrometers, more preferred from 25 to 80 micrometers, most preferred from 30 to 60 micrometers.
