Definitions

  • the present invention relates to a disposable self-heating container assembly for use for heating the contents of a container.
  • the devices may be classified according to the mechanism used for heat generation into four groups.
  • a first group employs hydration processes, a second employs acid-base reactions.
  • a third employs spontaneous oxidation-reduction reactions in aqueous solutions, and a fourth employs kinetically non-spontaneous oxidation-reduction reactions between solid oxidant and a solid reductant.
  • Each group will now be addressed in turn.
  • a second approach employs mixing of acids and bases.
  • a recent patent that takes advantage of this approach is U.S. Pat. No. 5,935,486 to Bell et al. that involves mixing of various organic and inorganic acids and bases.
  • the third approach uses oxidation-reduction reactions occurring in the aqueous phase.
  • Examples of this type include U.S. Pat. No. 5,517,981 to Taub et al. in which magnesium is mixed with cupric chloride in the presence of water and the U.S. Pat. No. 3,998,749 to Hydro et al. where aluminum and cupric chloride are mixed in a mixture of aqueous and organic solvents.
  • Oxidation reactions of this type are highly exothermic, providing greater heat per unit storage volume than hydration reactions.
  • the use of such reactions also presents certain problems. Firstly, the reactions tend to progress very rapidly, making it difficult to ensure efficient heat transfer to the liquid food. Furthermore, because of the need for the presence of some water, substantial energy is wasted in heating the water or boiling part of it. Finally, most reactions in this group produce significant quantities of dangerous gases such as hydrogen, and the waste solution may include hazardous substances, leading to numerous safety and environmental problems.
  • a fourth group of devices achieve significant advantages of efficiency, simplicity of structure and controllability by using solid phase self-propagating high-temperature synthesis (SHS) reactions, which include oxidation-reduction processes in the solid-state (such as thermite reactions).
  • SHS high-temperature synthesis
  • These reactions are basically redox reactions between metals or semimetals and metal oxide, such as aluminum, silicon and ferric oxide.
  • these reactions are gas-less processes that involve harmless materials, and generate large amounts of heat per unit volume (or weight) of the reagents.
  • the temperature of SHS reactions is above 1000° C., which requires good heat transfer and a safe metallic inner container.
  • the rate of reaction may be controlled by appropriate choice of metals and metal oxides, grain size of the solids and path of reaction. Since the reactions are not kinetically spontaneous at room temperature, the components may be safely and conveniently mixed within a single chamber until activated by the user.
  • the fuel is a mixture of a metal or alloys, such as silicon or ferrosilicon and a metal oxide, such as ferric oxide or cupric oxide.
  • the present invention provides a disposable self-heating container assembly for use for heating the contents of a container, a heating unit for use in the assembly, a disposable self-heating container convenience package for storage, sales and end usage, and corresponding method for heating the contents of a container.

  • FIG. 1 shows a preferred embodiment of a disposable self-heating-container assembly, constructed and operative according to the teachings of the present invention, which employs a disposable heating unit for heating a stored liquid.
  • the assembly employs a disposable heating unit which has a housing 10 including a first region 12 containing a combination of at least two solid substances which undergo a primary reaction that is an exothermic chemical reaction which is kinetically non-spontaneous at room temperature requiring relatively high activation energy.
  • the housing further contains an ignition region 14 , adjacent to first region 12 , which contains a second combination of solid substances which undergo an exothermic chemical reaction defining at least one intermediate reaction.
  • This intermediate reaction is also kinetically non-spontaneous at room temperature but has a relatively low activation energy. This provides the relatively high activation energy for the primary reaction.
  • An ignition mechanism 16 containing a primer and an ignition pin, is configured for ignition of the primer substantially within the ignition region 14 .
  • Pyrotechnic primers such as percussion primers and stab primers are devices well known to those skilled in the art of pyrotechnics.
  • the composition and structure of primers is taught in numerous patents, such as U.S. Pat. Nos. 5,466,315 and 5,717,159, The primer used here is a stab primer.
  • the ignition pin penetrates into the primer, the primary pyrotechnic material is ignited as a result of the heat generated by the friction of the penetration.
  • Operation of the assembly is as follows. Firstly, the ignition pin ignites the primer initiating an intermediate exothermic reaction of the substances in the ignition region 14 . The heat generated by this reaction is sufficient to provide the required activation energy to initiate the reaction of the solid substances in the first region 12 . This latter reaction then progresses, generating beat which is transferred through housing 10 to the contents of the container. This method of using a chain of reactions to initiate a primary reaction is well known within the art of pyrotechnics.
  • the present invention is applicable to a very wide range of applications in which a liquid (used herein to refer also to a mixture of solids together with a liquid) needs to be warmed, heated, boiled or cooked in circumstances in which conventional heat sources are unavailable, unsafe or inconvenient.
  • the invention may be used for heating water which may be used for preparing drinks, instant soups and the like, or for a range of other uses such as personal hygiene.
  • beverages, soups or solids such as vegetables mixed in water or other liquids may be heated directly within the container. All such applications are referred to generically as “liquid food” applications.
  • Other possible non-food applications include, but are not limited to, heating of fumigants and various chemicals for any purpose required.
  • the heating element of the present invention may be produced in numerous forms suited to a wide range of different applications.
  • the heating unit is part of a disposable container which is used to store a liquid prior to use, and then to heat and dispense the liquid on demand. The entire assembly is then discarded.
  • the heating element may be a replaceable insert within a reusable container, forming what may be regarded as a kettle operated by single-use replaceable inserts.
  • the heating unit may be implemented as a free-standing heating element for immersion into a container in a manner similar to an electric immersion heater.
  • the primary reaction is a solid-solid exothermic reaction which is kinetically non-spontaneous at room temperature and pressure requiring relatively high activation energy while the intermediate reaction is a solid-solid exothermic reaction which is kinetically non-spontaneous at room temperature and pressure requiring relatively low activation energy, and the intermediate reaction being initiated by ignition of a primer.
  • the primary reaction is an oxidation reaction between a metal, semimetal, metal alloy, metal-semimetal alloy or mixtures thereof with one or more metal oxide.
  • silicon is combined with a metal, typically iron or aluminum, to achieve a slower rate of reaction than when using a metal alone.
  • a preferred rate of reaction has been observed when using a ratio, by weight, of silicon to aluminum of greater than 1:1, and preferably about 2:1.
  • a preferred example of the metal oxide is ferric oxide (Fe 2 O 3 ).
  • a preferred example of the overall composition of the solid substances of the primary reaction is about 22% silicon, about 11% aluminum and about 67% ferric oxide, by weight.
  • the rate of reaction can be further adjusted by varying the mechanical properties of the mixture.
  • Relevant parameters include the grain size of the particles, the degree of consolidation, and the path of the reaction as defined by the shape of the container.
  • this preferably employs a solid oxidant as the first reagent.
  • a solid oxidant include, but are not limited to, at least one of potassium permanganate, manganese oxide, potassium chlorate, barium peroxide and potassium nitrate.
  • the solid oxidant in the ignition region 14 is present together with a metal and/or semi-metal or alloy thereof.
  • a typical preferred example employs 22% aluminum, 5% silicon, and 73% KMnO 4 .
  • the ignition region 14 is preferably separate from the first region 12 which contains the mixture for the primary reaction, but can optionally be implemented overlapping or intermixed therewith. The physical properties of the solid within the ignition region 14 may be varied to affect the rate of reaction.
  • At least part of the ignition region 14 is disposed within a recess formed in first region 12 so that at least part of the ignition region 14 is substantially circumscribed by first region 12 .
  • FIG. 1 illustrates what is believed to be a particularly advantageous configuration for the disposable self-heating-container assembly of the present invention.
  • a container 18 which has a contained volume 20 substantially enclosed by a plurality of walls including at least one side-wall 22 , a bottom 24 and a cover 26 .
  • At least one of the walls, most preferably bottom 24 provides a recessed cavity 28 projecting into contained volume 20 .
  • Housing 10 is disposed within recessed cavity 28 so as to be displaceable relative to container 18 .
  • the ignition mechanism 16 is deployed between housing 10 and a surface of recessed cavity 28 , the ignition pin actuation block 40 is supported by the ignition mechanism housing 42 which also contains the primer which is ignited by relative displacement between housing 10 and container 18 .
  • displacement of housing 10 relative to container 18 serves as an actuation mechanism to cause ignition of the primer substantially within the ignition region 14 to initiate heating.
  • the displacement of the housing relative to the container is achieved by pressing the container 18 toward the base 110 thereby causing the ignition actuation block 40 to come into contact with the bottom 24 of the container.
  • the actuation block is then displaced into the ignition mechanism housing 42 thereby igniting the primer.
  • first region 12 closest to the outside of container 18 may be provided with a layer of material 34 which is stable at high temperatures and has a high heat-capacity, such as ceramics. This serves as a heat storage device, prolonging the period over which heat is given out by the heating unit.
  • material 34 provides an additional safety buffer zone between the intense heat of the reaction region and proximal surfaces external to the container.
  • the entire container 18 is preferably made from materials which can withstand high temperatures, typically steel or other metals approved for use with food, and is coated with an insulating material, typically plastic.
  • the heating element may optionally be located in positions other than in bottom 24 .
  • the recessed cavity may be formed in the cover.
  • This embodiment also illustrates certain additional safety features which, it should be appreciated, are equally applicable to any other embodiments of the invention described above. It should be noted that various options may be used to prevent accidental actuation of heating unit 10 prior to use. In the example illustrated here, actuation of heating element 10 is achieved by relative displacement of container 18 and a base portion 110 which are temporarily locked against relative movement by a spring locking element 112 which engages a slot 114 in each and must be removed prior to initiation. Additional or alternative structures which may be used to advantage to offer similar or complementary preventive properties include, but are not limited to, bayonet structures which must be rotated to allow relative vertical motion, and tear-off retaining elements such as a plastic retaining ring.
  • ignition mechanism 16 is shown clearly in FIG. 2. Specifically, ignition pin actuation block 40 is supported by the ignition mechanism housing 42 so as to align the ignition pin 46 with the primer 44 . As the base and container sections of the disposable self-heating-container assembly are pressed together, the ignition pin actuation block comes into contact with the bottom of the container. This, in turn, causes the ignition pin actuation block to move further into the ignition mechanism housing, causing the ignition pin to come into contact with the primer, thereby igniting the primer.
  • a further important feature is the use of a spout apparatus 88 that also acts as a pressure-released seal, and includes a dispensing spout 104 . It is an important safety consideration that there should not be a build up of pressure within container 18 during operation of the heating unit. In the prior art, this was addressed by ensuring that the container was opened prior to actuation the heating unit. This, however, raises a different safety issue, namely, the risk of overheating in the event that the user were to pour out the contents of the container prior to or during operation of the heating unit.
  • An alternative approach to avoiding problems of pressure build up, while also preventing premature emptying of the container is the use of a pressure-released seal such as is shown here.
  • spout apparatus 88 is formed from a flexible hollow plug 90 which fits into an aperture 92 .
  • Plug 90 has a radially projecting ridge 94 which is slightly oversized for aperture 92 but which can be inserted due to the flexibility of the plug material.
  • Plug 90 also features a cylindrical recess 96 that narrows to an opening 98 in the portion of the plug that is inserted through the aperture.
  • a lock element 100 is slidable within recess 96 of plug 90 between a locked position, shown here, and a pressure-released dispensing position.
  • lock element 100 becomes locked by friction against side of the recess that is pressed between the lock element and the periphery of aperture 92 such that lock element 100 cannot be removed. This prevents premature emptying out of the contents of container 18 , since lock element 100 blocks the dispensing passageway between holes 98 and 102 .
  • the heating unit is actuated, the temperature of the contents of the container starts to rise. When the water content reaches a predefined temperature, typically about 95° C., sufficient steam pressure is generated to displace lock element 100 to its pressure-released dispensing position.
  • lock element 100 When lock element is displaced to its pressure-released dispensing position, the hot contents of the container may be dispensed through holes 98 and 102 , and spout 104 respectively. As shown here, the spout 104 is positioned back from the edge of the container cover so as to inhibit oral consumption of the heated liquid directly from the container. It should be noted that lock element 100 may further be held in place by components such as shear-pins or having a small protrusion from lock element 100 , which is releasable at a predetermined pressure, fit into a grove in plug 90 .
  • this spout apparatus provides a highly advantageous combination of properties for applications in which a fluid to be heated is stored in container 18 prior to use, since the container cannot be emptied prior to or during operation of the heating unit. At the same time, since the seal is released automatically by pressure increase within the container, excessive pressure build up is avoided. In addition, in cases of extreme pressure build, possibly caused by the malfunction of the moving parts of the seal, the entire flexible plug would be ejected from the aperture thereby releasing the pressure. In such an event, the flexible plug would remain connected to the container by the safety retaining strap 106 which is fixed to the cover of the container.
  • the liquid food within the container is at boiling temperature, which is too hot to consume.
  • a major consideration in the design of the spout is to prevent the user from consuming the liquid food directly from the container.
  • the spout enables the user to conveniently pour the liquid food into the receptacle described in FIG. 4 below. During this process, the liquid food comes into contact with the ambient air and is thereby sufficiently for consumption. This is the same principle as pouring a liquid from a kettle into a cup.
  • FIG. 4 shows additional features of the disposable self-heating-container convenience package for storing, selling and heating a stored liquid.
  • at least one serving receptacle may be secured over the cover of the container.
  • the attached serving receptacle serves two purposes. Firstly, it directly provides the needed serving receptacle to aid in the cooling process of the heated liquid as mentioned above Further, it provides a storage volume for supplemental food items such as cookies, crackers, or candies.
  • the serving receptacle may vary in size and shape depending on the size of the container and the serving requirements of the liquid inside.
  • the container may have a larger circumference and the serving receptacle may be in the form of a bowl with a spoon and crackers inside.
  • the serving receptacle may be in the form of a cup with a cookie, and sugar and creamer packets inside.
  • multiple-serving sized containers there may be two or more serving receptacles, each containing a supplemental food item.
  • the embodiment shown here includes an elongated larger sized container 18 , fitted with two cups 120 .
  • the convenience package as illustrated, could provide heated beverage, cups, cookies, sugar and creamer for two people.
