Definitions

  • the invention relates to a water soluble package according to claim 1, to a process for producing a water soluble package and to a process for washing of laundry.
  • Detergent compositions for the machine washing of laundry are provided in many forms.
  • Probably the most prevalent form of laundry detergent is washing powder or granules.
  • a problem with the use of these forms of detergent is that the product needs to be dosed into the machine in such a way that the detergent is quickly and thoroughly dissolved in the wash water of the machine without coming into contact with the laundry in a solid form.
  • many dosing devices which seek to overcome this problem have been proposed.
  • 0 343 070 and 0 343 069 teaches the use of a flexible fabric sock which holds the particulate detergent in the machine, the fabric of the sock being permeable to water so as to allow water enter the sock and carry the detergent out of the sock through the fabric walls in the form of an aqueous solution.
  • More recently unit dose forms of detergent have been proposed in the form of compressed tablets of detergent powder.
  • a problem encountered with the provision of detergent tablets is that the tablets need to be strong enough to withstand storage and transport, yet weak enough to disintegrate and dissolve quickly in the washing machine.
  • a further problem is the need to prevent the tablets "posting" in the porthole and between the drums of conventional washing machines.
  • a water soluble package according to claim 1 a process for producing a water soluble package and to a process for washing of laundry.
  • the thermoformed body wall of a package according to the invention is of substantially uniform thickness.
  • substantially uniform it is meant that at any measured point the thickness of the thermoformed film is preferably less than about ⁇ 25%, even more preferably less than about ⁇ 20% and most preferably less than about ⁇ 15%, different from the original thickness of the film pre-thermoforming.
  • the film has a thickness of between 10 and 1000 microns. More preferably the film has a thickness of between 20 and 80 microns, most preferably between 40 and 60 microns.
  • the first sheet of water-soluble material is thermoformed by means of a heating plate.
  • the sheet of water-soluble material intimately contacts the heating plate, typically by applying a vacuum between the heating plate and the sheet of water-soluble material.
  • the vacuum applied will be of less than 6000 Pa (0.6 Bar).
  • the sheet may be blown into contact with the heating plate.
  • the thermoforming sheet can be blown or sucked off the heating plate and into a suitable dome-shaped mould.
  • the process includes an additional step of, prior to the addition of the fluid substance, applying a vacuum to the thermoformed body wall to maintain the shape of the body portion at least until after the heat sealing step.
  • thermoforming process where a number of packages according to the invention are produced from two sheets of water soluble material.
  • recesses are formed in the sheet using a forming die having a plurality of cavities with dimensions corresponding generally to the dimensions of the packages to be produced.
  • a single heating plate is used for thermoforming the film for all the cavities, and in the same way a single sealing plate is described.
  • a first sheet of polyvinyl alcohol film is drawn over a forming die so that the film is placed over the plurality of forming cavities in the die.
  • Each cavity is generally dome shape having a round edge, the edges of the cavities further being radiussed to remove any sharp edges which might damage the film during the forming or sealing steps of the process.
  • Each cavity further includes a raised surrounding flange.
  • the film is delivered to the forming die in a crease free form and with minimum tension.
  • the film is heated to 100 to 120°C, preferably approximately 110°C, for up to 5 seconds, preferably approximately 700 micro seconds.
  • a heating plate is used to heat the film, which plate is positioned to superpose the forming die.
  • a vacuum of 0.5. MPa (0.5 bar) is pulled through the pre-heating plate to ensure intimate contact between the film and the pre-heating plate, this intimate contact ensuring that the film is heated evenly and uniformly (the extent of the vacuum is dependant of the thermoforming conditions and the type of film used, however in the present context a vacuum of less than 0.6 MPa (0.6 bar) was found to be suitable)
  • Non-uniform heating results in a formed package having weak spots.
  • thermoformed film is moulded into the cavities blowing the film off the heating plate and/or by sucking the film into the cavities thus forming a plurality of recesses in the film which, once formed, are retained in their thermoformed orientation by the application of a vacuum through the walls of the cavities. This vacuum is maintained at least until the packages are sealed.
  • the composition in this case a non-aqueous liquid detergent is added to each of the recesses.
  • a second sheet of polyvinyl alcohol film is then superposed on the first sheet across the filled recesses and heat-sealed thereto using a sealing plate.
  • the heat sealing plate which is generally flat, operates at a temperature of about 140 to 160°C, and contacts the films for 1 to 2 seconds and with a force of 8 to 30kg/cm 2 , preferably 10 to 20kg/cm 2 .
  • the raised flanges surrounding each cavity ensure that the films are sealed together along the flange to form a continuous seal.
  • the radiussed edge of each cavity is at least partly formed by a resiliently deformable material, such as for example silicone rubber. This results in reduced force being applied at the inner edge of the sealing flange to avoid heat/pressure damage to the film.
  • the packages formed are separated from the web of sheet film using cutting means. At this stage it is possible to release the vacuum on the die, and eject the formed packages from the forming die. In this way the packages are formed, filled and sealed while nesting in the forming die. In addition they may be cut while in the forming die as well.
  • the relative humidity of the atmosphere is controlled to ca. 50% humidity. This is done to maintain the heat sealing characteristics of the film.
  • the objective of this experimental work was to create thermoformed packages different shapes from the same material under the same conditions with the same depth of draw and approximately the same volume.
  • the formed packages were then tested for thickness at specific points using a micrometer. The results were then compared between shapes,
  • the rectangular shape shown is used only as an example to show the various points.
  • Points A & E are the same.
  • Points B, C and D are all equivalent in the dome shape and they were represented by Point F below.
  • the objective of this test was to show any differences, which exist, between the impact resistance of the dome shape and other shapes.
  • test specimen was placed on a hard surface immediately below the suspended dart. The dart was allowed to fall, striking the specimen centrally. The specimen was then examined and any rupture or leak recorded. If there was no rupture or leak, the specimen was subjected to successive impacts, each at a higher dart weight, until rupture did occur.
  • Dome, triangle (ie triangular pyramid) and cube shapes were tested.
  • Each package was formed from polyvinyl alcohol supplied by Chris Craft under reference CC8534.
  • the film thickness was 75 ⁇ m.
  • dome-shaped packages according to the invention containing a liquid laundry detergent, were placed randomly in a fibreboard box.
  • the box was made of "M-flute" material of dimensions 170 x 85 x 54 mm which had a total filled weight of 609g.
  • the box was sealed closed and subjected to a vertical drop of 1.2 m on to a hard flat surface on the short dimensions.
