  • an interior compartment normally containing water
  • an exterior compartment containing, for example, a salt.
  • EP 454912 describes a cooling pack in which the separated compartments contain an ammonium salt and urea, if necessary, in order to achieve a very good cooling effect.
  • U.S. Pat. No. 4,049,408 discloses a cooling pack for blood samples in which double-compartment containers containing ammonium nitrate in one compartment and water in the other compartment and being integrated in a wrappable cover are, after bringing together the two reacting components, wrapped around a cylindrical blood sample thus ensuring its cooling.
  • a hot pack to be applied on the human body is known from U.S. Pat. No. 4,057,047 in which water contained in an interior compartment having a perforation and water-free magnesium sulphate in a tightly sealed exterior compartment are brought into contact with each other.
  • the exothermal reaction is used, for example, to warm up limbs of sportsmen in winter.
  • the multi-compartment pack comprises a first compartment containing a solid matter or a liquid and an adjacent second compartment temporarily separated from said first compartment and containing a liquid, wherein, if the temporary separation of said compartments is eliminated, the substances in both compartments get into contact with each other and cause an endothermal or exothermal reaction, said pack being characterized according to the present invention in that at least one wall of the first compartment and one wall of the second compartment form at the same time a permanent whole contact area to a third compartment, which contains a product to cool or to heat; the first compartment and the second compartment are in contact with the third compartment solely via the contact area; the liquid present in both compartments after interrupting the separation at a sealing between the first compartment and the second compartment makes possible an interchange of heat by transfer via the whole contact area to the third compartment; and the third compartment comprises an opening easily to be opened from the outside from which the heated or cooled product can be taken out following the reaction between the substances contained in the first and second compartments.
  • the contact area consists of a material inert towards the reaction partners and which has a good heat conductivity.
  • a heat-conducting material are aluminum foil, that may be coated with a plastic material such as polyethylene, Saran, polypropylene, polyethylene terephthalate, polyester, polyvinyl acetate, polyvinyl chloride; copolymers of that polymers; and mixtures thereof.

  • the contact area may be formed as a corrugated or wafer-like structure in order to achieve a further extension of its surface.
  • contact area is meant to describe the area between each of the two compartments containing the heating or cooling substance and the liquid belonging to it, and the compartment containing the product that is to be heated or cooled.
  • Whole contact area is the total area created by the sum of the contact areas of the first and the second compartment to the third compartment.
  • the first chamber contains a dry substance being selected among calcium oxide, calcium chloride, zeolite Beta, zeolite faujasite X, zeolite faujasite Y, zeolite ZSM-5, mordenite, and mixtures thereof.
  • zeolites of the structural classes A, chabasite, ERI (erionite), MEL (ZSM-11), MTT (ZSM-23), OFF (offretite) may be used as well provided that they are commercially available, aluminium-rich, and thus hydrophile.
  • Further materials may be used such as magnesium sulfate, sodium acetate, ferric chloride, calcium chloride, magnesium chloride, zinc chloride etc. which should be anhydrous.
  • the first compartment may contain a dry substance being selected among ammonium nitrate, urea, potassium chloride, stannic chloride, ammonium bromide, cobalt chloride, and mixtures thereof, all of them should be anhydrous.
  • the ratio between the agents involved in the reaction to achieve a suitable exothermal or endothermal reaction can be determined by a person skilled in the art. Preferably, this ratio ranges between 1:0.8 and 1.3 with relation to the weight of the reactants being a chemical reaction agent (salt):water.
  • the weight ratio between the reactants and the product to be cooled or heated can also be determined by a person skilled in the art and defines the degree of temperature change within the product itself. The range temperature change to be achieved for the product is 1° C. 60° C.
  • reaction temperature can be lowered e.g. by 20 to 40° C., thus cooling down the contacted cosmetic or pharmaceutical product by 5 to 20° C. after a short waiting time of 0.1 to 3 minutes depending upon the dimensions of the contact area.
  • water particularly deionized water
  • Impurities in tap water may be detrimental to package stability and may affect reactions.
  • all compartments are formed to be flat with the ratio between the respective side wall height of one compartment and its length or width being in the range of 1:20-300 and wherein the contact area between the third compartment and the first compartment or the first and second compartments respectively represents the largest basic area of a compartment.

  • the top areas of all compartments i.e. those areas facing the outside instead of another compartment, are made of a thermally insulating material in order to enhance the cooling effect towards the contact area.
  • a thermally insulating material are thin foamed foils, e.g. from polystyrene which are optionally reinforced with other plastics, such as films. While heat-insulating materials may be preferred, the use of thermal conducting materials may be required to facilitate production and/or reduce costs.
  • a further embodiment of the invention is a multi-compartment pack wherein at least a part of the first compartment and the second compartment is integrated within the third compartment.
