Definitions

  • This invention relates to packs primarily intended for detergent powder, such as drums and cartons.
  • the invention provides a pack containing a solid substrate having liquid absorbed thereon, the liquid having a tendency to bleed from the substrate, the pack having an open-pored surface on its inside face.
  • the invention also provides a pack suitable for containing a detergent powder comprising a nonionic surfactant or other liquid substance having a tendency to bleed from the powder, in which the open-pore surface on the inside face of the pack is formed by applying a non-woven fabric to the sheet material from which the pack is formed.
  • the invention also provides a blank for the pack described.
  • the invention in both its major aspects relates to a pack having an open-pore surface internally.
  • the latter term is used herein to denote a surface in which the smallest pores are no smaller than the pores in the substrate from which the liquid is expected to bleed.
  • the minimum pore diameter of the surface will be approximately 0.1-20 microns.
  • the maximum pore diameter is governed by the following consideration, that if the largest pores are larger than the smallest particles in the solid, then some of the powder may stick to the open-pore surface and not dispense. Consequently it is preferred, though not essential to the invention, that the maximum diameter of the pores is approximately 50-500 microns.
  • the open-pore surface referred to in the first aspect may be formed in any desired manner.
  • it may be formed by treatment of the sheet material itself from which the pack is made, for example by heat or by spraying with a foamable material.
  • the sheet material is cardboard
  • the open-pore surface may even be formed by adding a gassing agent to the surface of the board during the final stage of manufacture.
  • Foamed. plastics of the .open cell type may also be used as linings for the pack and these may either be co-formed with or adherent to the sheet material from which the pack is made.
  • the detergent powder which is present in the pack in accordance with the preferred aspect of the invention will generally contain from 5 to 25% by weight of a liquid or pasty nonionic surfactant.
  • Detergent powders containing lower amounts of nonionic surfactant than this generally having sufficient inherent absorbency not to exhibit the bleeding phenomenon. However, the powder may still exhibit bleeding due to the presence of large amounts of, for instance, mobile perfume components or polysiloxane anti-foam components.
  • the non-woven fabric should be formed from a substance which is readily drawn into fibres, for example a cellulosic material such as cotton, proteinaceous material such as wool or silk or hair or other materials such as substantially linear plastics polymers, particularly acrylic polymers.
  • a cellulosic material such as cotton, proteinaceous material such as wool or silk or hair
  • substantially linear plastics polymers particularly acrylic polymers.
  • very many other materials can be used such as glass and carbon fibre, asbestos and polyurethanes.
  • the packs of the first and second aspects of the invention are either cylindrical or rec- tanguloid.
  • the invention includes the corresponding blanks.
  • This experiment confirms the efficacy of a thin layer of non-woven fabric in protecting a cardboard carton from the effects of bleeding from a detergent powder.
