Definitions

  • the present invention relates to a multip le-compartment container for packaging products that must be kept separated during transport and storage and that are mixed within the container only when used.
  • One advantageous application o f the invention is the use of the multip le-compartment container for packaging cosmetic products, such as cosmetic products for dyeing human keratin fibers.
  • Other advantageous applications o f the invention may be the use of the multip le-compartment container to store care products, adhesive products, polymer coatings, flavored liquids, etc.

  • the frangible seal can be ruptured by exerting a manual pressure to the envelope.
  • frangible seal has sufficient strength to not be ruptured or compromised until a predetermined amount of pressure is applied to the container.
  • a "compromised seal” should be understood as a seal which allows a communication between the housed products.
  • the multiple-compartment container must be designed such that the required breaking force pressure to apply is limited.
  • the frangible seal must rupture easily in order to satisfy a consumer in search of effective products, and notably a consumer using such a container packaging cosmetic products.
