Definitions

  • the present invention is in the field of hot and cold beverages, such as coffee. tea, soft drinks, and soups, as well as other ingestible products that are consumed at non-ambient temperature, such as baby food and medicines.
  • the invention enables to store and carry food and drink products at ambient temperature conditions, and to bring them to the desired temperature just before using them, without using external energy sources. It is also possible to embody the heating device that constitutes a component of the beverage can, as a stand-alone product for heating any type of beverage or food.
  • US Patents 4523,083, 4914920 and 5549219 teach methods of heating and cooling beverages and food products, requiring exterior means and none of them is a self-contained, autonomous device.
  • US Patent 5626022 presents a container with an integral material cavity containing a solid reactant while the liquid reactant being contained in a separate cap. By depressing an actuator disc, prongs break the barrier between the reactants, initiating an exothermic/endothermic chemical reaction.
  • US Patent 5370107 teaches a beverage can heated by a charge which is ignited using a piezo-electric initiation system. The medium in the piezo-electric generator that generates the spark is oxygen, which is sealed in a closed container containing the electrodes as well.
  • the present invention provides methods of heating/cooling a beverage or a food can which are self-contained and therefore are adequate for use at any location and at any time, without any need for water, electricity, heating/cooling appliances or any other additional means.
  • Heating/cooling are achieved by activating an exothermic/endothermic chemical reaction, without using external energy sources.
  • the chemical reacting substances are stored in one unit with the product container.
  • the materials used as reactants have a high specific heat and a high rate of reaction. Physical separation (possibly double-wall design) between the chemical reactants and the ingestible product prevents any mixing or contact.
  • the reactants are completely safe, and no spontaneous reaction will occur as a result of heating, mechanical shock, drop, impact or any other conditions which might occur during normal storage, transportation and handling.
  • the can Prior to activating the chemical reaction, the can is opened, in order to prevent pressure build-up as the boiling takes place. This precondition is implemented mechanically.
  • the structure of the can is provided with appropriate thermal insulation in order to prevent injury or inconvenience due to the high temperature of the beverage/food and of various parts of the cans a result of the exothermic reaction.
  • the present invention applies chemical heating/cooling to the beverage and food industry. In this field, there are special requirements in terms of safety, reliability and price. Also, special attention has been given to achieve a heating/cooling rate adequate for the immediate consumption of the beverage or food after opening the can. In order to achieve a high temperature after heating, irrespective of the initial temperature, a heating device generating sufficient heat is required.
  • the present invention has the following advantages: a. Only a small percentage of the overall can volume and weight is dedicated to the heating device, as the heat of reaction of the reactants (solid and liquid) is relatively high. b. Fast reaction rate and subsequently short heating time. c. Final temperature independent of initial temperature, as liquid is always brought to boiling temperature. d.
  • Absolute safety due to design preventing bursting of the can in case of activation of heating system this feature being a result of physically preconditioning the activation on opening the can or on a controlled weakening of part of the can, which can serve as a "fuse" in case of excessive pressure buildup and/or arriving at a specified temperature.

  • the present invention is of a container which can be used to store a substance and to heat or cool the substance prior to use.
  • the present invention can be used to heat or cool the substance to an extent that induces a phase transition such as boiling, without damage to the container, because the container is constructed so that the part of the container that holds the substance is opened to the outside air either before or while the heating/cooling mechanism is activated. This ensures that the pressure inside the container remains the same as the pressure outside the container, despite large volumetric changes in the contained substance associated with the phase transition.
  • Figure 1 illustrates a container 100 of the present invention.
  • Container 100 is based on a can 1 containing a beverage 2.
  • Can 1 is equipped with a safety cover 3 on its lid 4.

  • Heating device 6 contains as reactants a metallic component 7, such as magnesium, an electrolyte 8, and an additive 9 such as cupric chloride to scavenge hydrogen gas precursors in order to prevent release of hydrogen gas, and a plunger 10 which when being depressed cause the reactants to mix and to undergo a highly exothermic chemical reaction, bringing beverage 2 to boiling.
  • Safety cover 3 is physically connected to lid 4 beneath a conventional pull-tab 40, and removing safety cover 3 from left to right using pull-tab 40 first creates an opening at point 14 in lid 4 and only afterwards exposes plunger 10. In this way, before plunger 10 can be depressed, lid 4 is partially opened and thus pressure build-up in can 1 is prevented.
  • FIG 2 illustrates in more detail heating device 6, which can be part of container 100, as in Figure 1 , or can form a stand-alone item, as an immersion heater, which can be used to heat any beverage or food in an open vessel.

  • plunger 10 When the user of the device of Figure 1 presses on plunger 10, a shear pin 17 is sheared and plunger 10 causes the reactants to mix and to undergo a highly exothermic chemical reaction.
  • a cooling column 18 is incorporated in the plunger 10 for the condensation of the vapor generated by the reaction with the purpose of recycling the condensed vapor to continue the reaction.
  • heating device 6 As an immersion heater, heating device 6 is immersed in a beverage to be heated, or heating device 6 is inserted in a food to be heated, and plunger 10 is depressed.

  • Removing safety cover 33 uncovers plunger 10 and enable pressing on plunger 10, in a condition where there is no danger of high pressure build-up because the pressure of steam from boiling beverage 2 breaks the seals of openings 44 before a dangerously high level of pressure is reached inside can 1.

  • Lower body 34 contains, as a first reactant, a solid metallic component 7 such as magnesium, and also an additive 9 such as cupric chloride that prevents release of hydrogen gas.
  • Upper body 35 contains, as a second reactant, a liquid electrolyte 8, a cooling column 36 which typically is a highly porous metallic body such as a wire lattice, a sealing cover 37 and a pull rod 38.
  • Safety cover 3 is physically connected to lid 4 beneath a conventional pull tab 40.
  • Safety cover 3 also is physically connected to pull-rod 38. Removing safety cover 3 using pull-tab 40 creates an opening at point 14 in lid 4, to expose beverage 2 to ambient pressure, while pulling pull-rod 38 to initiate the reaction of reactants 7 and 8 in one continuous motion. The almost simultaneous, consecutive exposure of beverage 2 to ambient pressure and initiation of the reaction of reactants 7 and 8 prevents the buildup of dangerously high pressure in can 1 as beverage 2 boils.

Abstract

L'invention concerne un récipient permettant de contenir une substance telle qu'une boisson puis de réchauffer ou de refroidir sans danger cette substance au point de l'amener à une phase transitoire, telle que l'ébullition. Le récipient comprend un compartiment extérieur permettant de contenir cette substance et un compartiment intérieur qui comprend un mécanisme de changement de température permettant de changer la température de la substance, et un mécanisme d'activation permettant d'activer le mécanisme de changement de température. Un mécanisme d'étanchéité étanchéifie le compartiment extérieur tout en bloquant l'accès au mécanisme d'activation. Le mécanisme d'étanchéité comprend également un dispositif permettant l'équilibrage sans risques de la pression entre le compartiment extérieur et l'environnement au moment où le mécanisme d'activation est actionné. Le mécanisme de changement de température et le mécanisme d'activation peuvent également être utilisés séparément comme appareil de réchauffement et de refroidissement submersible et autonome.
