Definitions

  • the present invention relates to a sealable container containing a substrate which incorporates a composition.
  • the composition comprises a cleaning and/or antimicrobial compositions.
  • the substrate in combination with the composition can be used to clean and/or disinfect animate surfaces (e.g., human skin, mouth) and inanimate surfaces including, but not limited to, hard surfaces like walls, tiles, table tops, glass, bathroom surfaces, kitchen surfaces, dishes as well as fabrics, clothes, and carpets.
  • compositions are well known in the art.
  • the compositions are available in many forms, for example, as liquids, sprays and more recently as wet wipes.
  • wet wipes provide an easy and fast way of cleaning and/or disinfecting any kind of surfaces. Indeed, wet wipes may be utilised in a variety of applications both domestic and industrial. Typically, wet wipes are used to clean and/or disinfect animate surfaces (e.g., human skin, mouth) and inanimate surfaces including, but not limited to, hard surfaces like walls, tiles, table tops, glass, bathroom surfaces, kitchen surfaces, dishes as well as fabrics, clothes, and carpets.
  • animate surfaces e.g., human skin, mouth
  • inanimate surfaces e.g., hard surfaces like walls, tiles, table tops, glass, bathroom surfaces, kitchen surfaces, dishes as well as fabrics, clothes, and carpets.
  • such wet wipes essentially consist of a substrate which incorporates a composition.
  • the composition used for cleaning wet wipes has to exhibit at least some cleaning performance benefits.
  • Disinfecting wet wipes can be similar to cleaning wet wipes, but the composition incorporated thereon additionally comprises a disinfecting material. It is generally recognised that such a disinfecting material greatly reduces or even eliminates microorganisms, e.g., bacteria, existing on a surface.
  • residual antimicrobial benefits are delivered over time (i.e., 12, 24 hrs) since the application is a non-rinsing one.
  • wet wipes consisting of a substrate which incorporates a composition are already known in the art.
  • WO 89/05114 discloses disposable wipes for hard surface cleaning which are impregnated with a liquid composition.
  • the cleaning and/or disinfecting performance benefits of the currently used wet wipes may still be further improved.
  • other key benefits sought include reducing the presence of residue on drying of the composition and improving shine. These benefits can in some instance work against each other and thus it is the constant effort of the manufacturer to provide improved cleaning and/or disinfecting performance without negatively impacting the level of remaining residue and/or shine.
  • a drawback associated with the currently used wet wipes is that fluid, including the composition incorporated onto the substrate may partially or even completely evaporate during storage, resulting in the drying of the wipe. Drying of the wipe significantly reduces the cleaning and/or disinfecting performance originally provided by the wet wipes.
  • wet wipes can be packaged in a closeable container, for example a plastic box, as described in the Applicant's co-pending patent application EP 99870131.2.
  • the evaporation of the composition may still take place even though a closeable container is employed, this may for example be due to the insufficient sealing or complete lack of sealing provided by such containers and/or insufficient closing mechanisms of such containers.
  • the reduction or prevention of the evaporation of the composition incorporated onto a substrate may still be further improved.
  • sealable container containing a substrate which incorporates a composition comprising a multiple surfactant system according to the present invention.
  • WO 89/05114 discloses disposable impregnated wipes for cleaning hard surfaces impregnated with an aqueous composition comprising at least one water-miscible solvent.
  • US 4,666,621 discloses pre-moistened wipes for cleaning hard surfaces impregnated with a liquid cleaning solution comprising surfactants and up to 40% of a monohydric aliphatic alcohol of 1 to 6 carbon atoms.
  • the present invention encompasses a sealable container containing a substrate which incorporates a composition comprising (i) an anionic and/or cationic surfactant, (ii) a nonionic surfactant and (iii) an amphoteric and/or zwitterionic surfactant.
  • the present invention directed to a process according to claim 22.
  • the present invention relates to a sealable container containing a wipe comprising a cleaning composition.
  • the container as used herein must be sealable.
  • the container is re-sealable, meaning that it can be opened and then re-sealed.
  • the container comprises a container body having at least one opening and a sealable element, more preferably a re-sealable element by which the container can be sealed.
  • the container may be for example a box, bag, pouch, envelope or any other suitable construction.
  • the container is made using any suitable material. More preferably the container is made from plastic and/or metal.
  • the container herein is a box, wherein said box is molded from a polypropylene material or any other suitable thermoplastic materials such as polyethylene, polystyrene, acrylonitryl butadiene styrene (ABS), polyester, polyvinyl chloride, polycarbonate or elastomer, or a blend of these compounds.
  • the container herein is a pouch, wherein said pouch consists essentially of a laminate film of polyethylene, polypropylene and/or other suitable thermoplastic materials.
  • the substrate incorporating the composition i.e. the wipe
  • the pouch housed within a box.
  • the sealable element may be, for example a lid, hatch, cover or any other suitable means which occludes the opening of the container body.
  • the container when sealed is substantially airtight.
  • the container when in the airtight sealed position, the container is substantially impermeable to air, even through the container opening.
  • the container is as described in co-pending Application number EP 98870244.5.
  • the substrate according to the present invention incorporates a composition comprising a surfactant system.
  • the substrate is provided by a web, typically as a sheet of material cut from the web.

  • Man-made fibres includes fibres manufactured from cellulose, either derivative or regenerated. They are distinguishable from synthetic fibres which are based on synthetic organic polymers.
