Definitions

  • the present invention relates to an arrangement for beverage and/or food in which the beverage and/or food can be heated or cooled by self-contained structure in the arrangement.
  • a variety of arrangements for self-heating or self-cooling beverage and/or food have been proposed in the prior art.
  • the arrangements typically include a reaction volume in which liquid and solid reactants combine, when desired, to create heat or cold, which is then imparted to a container for beverage and/or food.
  • a container for beverage and/or food are proprietary in design. This usually increases the overall expense of manufacture since government regulations or standards must be specially met for the proprietary container.
  • the invention provides an arrangement for heating or cooling a pre-sealed container for beverage and/or food includes a reaction vessel with a reaction volume in which first and second reactants intermix when desired to change the temperature in the reaction volume.
  • a pre-sealed beverage and/or food container thermally contacts the reaction volume, and has a generally tubular shape with a bottom, and a top with means for opening the container.
  • a lid surrounds, and is sealed to, the top portion of the container, for enclosing part of the reaction volume.
  • Confronting surfaces of the top portion of the container and the lid have respective cooperating, portions shaped in an overall tapering manner, more narrow towards the top of the container, so that downward pressure from the lid towards the container substantially aids in holding the container against a bottom support for the container.
  • a seal is positioned between the confronting surfaces.
  • a mid-ring separate from the reaction vessel is positioned generally mid-way between top and bottom of the reaction vessel.
  • the mid-ring supports the bottom of the container and is interposed between the bottom of the pre-sealed container and the membrane. Stop structure within the reaction vessel provides a stop to downward movement of the mid-ring.
  • the foregoing embodiments of the invention provide arrangements for self-heating or self-cooling beverage and/or food that can use standard, commercially available containers for the beverage and/or food. Such arrangements can beneficially have a simple construction.
  • FIG. 1 is a side view, partially cutaway, partially in cross section and with portions removed, of an exemplary self-heating/cooling arrangement for beverage and/or food according to the invention.
  • FIG. 2 is a side view, partially cutaway, of a container of the arrangement of FIG. 1 .
  • FIG. 3 is an exploded, top perspective view of the inventive arrangement of FIG. 1 , without the temperature-changing reactants shown.
  • FIG. 4 a is an enlarged side view, partially in cross section, of an upper portion of the arrangement of FIG. 1 , without the temperature-changing reactants shown; and FIG. 4 b is an enlargement of the circled area in FIG. 4 a labeled FIG. 4 b.
  • FIG. 5 is a side view, partially in cross section, of a lower portion of the arrangement of FIG. 1
  • FIG. 6 is s top perspective view of the mid-ring shown in FIG. 5 .
  • FIG. 7 is a top perspective view of the lid of the arrangement of FIG. 1 .
  • FIG. 8 is a fragmentary view, partially in cross section, of a lid, taken at Arrows 8 - 8 in FIG. 7 .
  • FIG. 1 shows an overview of an inventive arrangement 10 for heating or cooling beverage and/or food in accordance with the invention.
  • Arrangement 10 includes a beverage and/or food container 12 that may have a pop top 13 for opening the container, may be pre-sealed, and may be made of aluminum.
  • Arrangement 10 also includes a reaction vessel 14 , preferably of plastic.
  • Reaction vessel 14 includes a reaction volume 16 in thermal contact with container 12 , for heating or cooling the contents of the container, depending on the composition of liquid 18 and solid 20 reactants.
  • Reactants 18 and 20 are normally separated from each other by a membrane 58 ( FIG. 5 ), but intermix with each other when membrane 58 is breached by a breaching member 22 .
  • a lid 24 is sealed to the top portion of container 12 , and is specially contoured to facilitate easy consumption of the contents of the container.
  • the bottom portion of the container may rest, directly or indirectly, against a so-called “mid-ring” 26 (i.e., a shortened version of “mid-vessel ring”).
  • a label 28 preferably of heat-shrink construction, covers the outside of generally tubular reaction vessel 14 , and can provide enough thermal insulation to prevent a user's hand holding the label from uncomfortable temperatures.
  • a spritz guard 29 is mounted over pop-top 13 for containing an outburst, or spritz, of beverage from container 12 that may occur after shaking the container in an operation (described below) for heating or cooling the contents of container 12 .
  • Spritz guard 29 preferably comprises a removable, pressure-sensitive label that is supple.
  • One example is 2 mil thick polypropylene.
  • a user pulls upwardly on tab 29 a which lacks adhesive—to remove the spritz guard. This would be accomplished, as written on the spritz guard itself, by instructions such as: “Break open the Pop Top [13] before peeling of this Spritz Guard consumer protection label.” As will be apparent from the present specification, a consumer would open pop top 13 after a heating or cooling operation has occurred.
  • Reaction vessel 14 and mid-ring 26 preferably comprise high impact polystyrene.
  • Spritz guard 29 preferably comprises a pressure-sensitive, removable label.
  • a typical heating or cooling operation of arrangement 10 proceeds in the following sequence: Invert the arrangement (i.e., turn it upside-down), and then breach membrane 58 , which is explained below, which causes liquid reactant 18 to start intermixing with solid reactant 20 . Then, shake the arrangement vigorously for at least about 45 seconds, which assists in thermal transfer between the reactants and the contents of container 12 , so that the contents more uniformly become heated or cooled to a desired temperature. The beverage and/or food in the container will typically reach a desired temperature for consumption within a few minutes.
  • Container 12 is preferably mounted in arrangement 10 through mechanical pressure, and preferably without adhesive. Such mounting can occur by suitable shaping of the container and associated lid 24 ( FIG. 1 ).
  • Container 12 is preferably a pre-sealed aluminum can, such as commercially prevalent for soft drinks or beer. By being pre-sealed, containers can be used in the inventive arrangement that have already passed all governmental regulations and standards for safely sealing beverage and/or food.
  • container 12 has a bottom portion 12 a and a top portion 12 b .
  • Top portion 12 b has a so-called “necked-in” region 30 below a double-seamed end 32 , and a “shoulder” portion 12 e below necked-in region 30 . Double-seamed end 32 connects a top 12 c of the container to a main body 12 d of the container.
  • the necked-in region causes top portion 12 b of the container to be shaped in an overall tapering manner, more narrow towards the top of the container.
  • Manufacturers of aluminum cans often reduce the amount of metal required to make a main body (e.g., 12 d ) of a can, below a double-seamed end (e.g., 32), by accentuating the amount of necking-in of the can. If the main body of the can is thin, the accentuated necking-in at the top of the can assures the presence of adequate metal required to form a proper double-seamed end. In any event, cans shaped in the desired, overall tapering manner are commercially quite prevalent.
  • FIG. 3 shows various parts of arrangement 10 of FIG. 1 that can mount container 12 by mechanical pressure.
  • Lid 24 preferably with the aid of a gasket 36 , applies downward pressure onto the top portion ( 12 b , FIG. 2 ) of the container.
  • the bottom portion (e.g., 12 a , FIG. 2 ) of the container is pressed upwardly by mid-ring 26 .
  • Mid-ring 26 may rest on an annular shelf in the vicinity of stepped region 42 of reaction vessel 14 .
  • lid 24 interacts with the top portion of container 12 and how mid-ring 26 interacts with the bottom of the container are now described.
  • top portion 12 b of container 12 is shaped in an overall tapering manner, more narrow towards the top of the container. Referring to FIGS. 4 a and 4 b , this is true in vertical region 46 of arrangement 10 .
  • surface 48 of lid 24 which confronts top portion 12 b of the container, is also shaped in an overall tapering manner, more narrow towards the top of arrangement 10 .
  • the mentioned configurations of the cooperating, confronting surfaces of the lid (i.e., surface 48 ) and of top portion 12 b of the container are chosen with respective dimensions so that downward pressure from the lid towards the container substantially aids in holding the container against a bottom support for the container e.g., mid-ring 26 ( FIG. 3 ).
  • dimension 49 of lid 24 ( FIG. 4 a ) may be about 40 mils less than dimension 47 of container 12 . This further causes the lid to hold the container downwardly in arrangement 10 .
  • gasket 36 provides a watertight seal between top portion 12 b of the container and lid 24 .
  • Gasket 36 cooperates with the cooperating, tapered configurations of the container and lid to hold the container downwardly against mid-ring 26 ( FIG. 3 ), for example.
  • gasket 36 may comprise a flat, annular band of compressible material, such as foamed plastic (e.g., foamed polyethylene) with a typical thickness between about 20 and 40 mils.
  • foamed plastic e.g., foamed polyethylene
  • Such material is commercially available as Part No. F-217, with a density of 23-27 pounds per cubic foot, from Tri-Seal, a division of TEKNIplex Co. of Blauvelt, N.Y. Inner diameter 36 a ( FIG.
  • unflexed gasket 36 preferably is substantially smaller than diameter 47 ( FIG. 4 a ) of the top portion of the container.
  • inner diameter 36 a of the gasket, before being stretched over the container may be 1.5 inches, the outer diameter of the gasket, 2.225 inches, and container diameter 47 , 2.050 inches, using the 20-mil foamed polyethylene gasket from TEKNIplex Co., as just discussed.
  • gasket 36 alone can fulfill the requirement of obtaining a watertight seal between lid and container.
  • adhesive (not shown) need not be used in addition to a gasket.
  • adhesive could be used to obtain a watertight seal, with or without a gasket, without departing from the invention.
  • the seal between lid 24 and container 12 is preferably formed by the squeezing of gasket 36 between a “shoulder” portion 12 e of the container and an adjacent portion of the lid.
  • reaction vessel 14 may be ultrasonically sealed to lid 24 in the areas shown at 50 . This will prevent accidental release of the contents of reaction volume 16 from reaction vessel 14 . A reliable weld can be easily achieved especially with vessel 14 and lid 24 both made of high impact polystyrene.
  • FIGS. 5 and 6 show details of mid-ring 26 to aid in explaining its function of supporting bottom portion 12 a of container 12 , as well as explaining further functions of the mid-ring.
  • mid-ring 26 is contoured to support bottom portion 12 a of the container.
  • mid-ring 26 has an annular channel, e.g., 26 a , that receives lowermost, annular extension 54 ( FIG. 5 ) of the container. This provides a reliable hold on the container.
  • channel regions 26 b in the mid-ring in cooperation with a central, vertical aperture 26 c ( FIG. 6 ) in the mid-ring, enable passage of liquid reactant, when desired, from one side of the mid-ring to the other—or, from the perspective of FIG. 6 , from below mid-ring 26 to above the mid-ring.
  • Mid-ring 26 provides another important function; that is, to make breaching member 22 effective.
  • mid-ring 26 may rest, indirectly (via membrane 58 ), on an annular shelf 14 a of reaction vessel 14 , in the vicinity of stepped region 42 of the reaction vessel.
  • Membrane 58 which may be a laminated induction heat seal, may extend for 225 mils, for instance on annular shelf 14 a . Other thicknesses for the membrane can be used, if desired.
  • breaching member 22 can reliably breach the membrane when moved upwardly in the reaction vessel, by having the mid-ring 26 , which may have an aperture 26 c of dimension 60 , rest atop membrane 58 . Breaching member 22 will move upwardly in the vessel when a user presses upwardly on lower, concave surface 14 b of the reaction vessel.
  • membrane 58 cannot resist breaching by bulging upwardly as would be the case without the mid-ring over it, by having mid-ring 26 situated atop membrane 58 , with a relatively smaller aperture 26 c for passage therethrough by breaching member 22 . Additionally, the membrane is more reliably pierced by breaching member 22 , allowing a thicker membrane to be used so as to avoid premature piercing of the membrane.
  • mid-ring 26 effectively reduces the unsupported surface area of the membrane from that of dimension 62 , the maximum horizontal dimension of the unsupported part of the membrane that is typically of 2.55-inch, to dimension 60 , which is typically one inch.
  • aperture 26 c preferably covers less than about 25 percent of the full area of the membrane, and more preferably less than about 15 percent of the full area of the membrane.
  • dimension 64 of breaching member 22 which is the maximum horizontal dimension of the breaching member, is preferably at least about 60 percent of dimension 60 of aperture 26 c of the mid-ring, and more preferably at least about 75 percent of such dimension. This helps assure that breaching member 22 reliably breaches the membrane with only a short distance of movement.
  • Mid-ring 26 is also designed to slow the flow of intermixed reactants 18 and 20 from reaction volume 16 back below membrane 58 after the membrane has been breached by breaching member 22 . This is desirable to assure that: (1) liquid 18 and solid 20 reactants intermix thoroughly to achieve the desired heating or cooling reaction and (2) that the intermixed reactants 18 and 20 conduct thermal transfer to the contents of container 12 for a prolonged period of time. With reference to FIGS. 5 and 6 , mid-ring 26 slows down the flow of the intermixed reactants 18 and 20 through two features.
  • Suitable materials for membrane 58 will be apparent to those of ordinary skill in the art.
  • One possibility is a laminated adhesive-aluminum foil-white paper sold by TRI-SEAL, a TEKNIplex Company, of Flemington, N.J., as Part No. HS 405 .
  • Such membrane has an adhesive thickness of about 2 mils, a foil thickness of about 0.35 mils, and a white paper thickness of about 3 mils, for a total thickness of about 5.35 mils.
  • FIGS. 7 and 8 show additional details of a novel topology for lid 24 of FIG. 1 .
  • lid 24 has an upwardly and outwardly facing surface 24 a that surrounds a top portion of the container 12 .
  • FIGS. 4 a and 4 b show another cross section of the lid, in which surface 24 a can be seen surrounding container 12 .
  • Surface 24 a typically extends upwardly at an angle from straight upward between about 5 and 45 degrees, and more preferably with a lower angle of 10 degrees and a higher angle of 20 degrees. Some portion of surface 24 a beneficially receives the lower lip of the mouth of a person consuming the contents of the container.
  • surface 24 a receives more than about 9.5 mm of a consumer's lip, and may be extended to receive a greater extent of a consumer's lip, such as 13 mm.
  • surface 24 b of the lid cooperates with surface 24 a to form a trough 24 c , which beneficially collects contents of the container that spill over the top of the container.
  • a 10-centimeter length of trough 24 c can hold between about 1 and 3 milliliters of volume of contents from the container when the container is vertically upright.
  • lid 24 preferably also includes another lip-receiving surface region 24 d .
  • Region 24 d includes a concave surface 24 e , which is generally vertical, and another surface 24 f , which may be flat, for instance.
  • region 24 d forms a drain from trough 24 c , which preferably can drain substantially all of the trough.
  • FIGS. 1 and 3 show label 28 , which, as mentioned above, is preferably of heat-shrink construction.
  • Label 28 beneficially may perform a thermal-insulating function with respect to the reactants 18 and 20 that, when intermixed, undergo a change in temperature.
  • label 28 may be tubular in shape. Upon being shrunk in a known heating process onto reaction vessel 14 and lid 24 , label 28 appears as in FIG. 1 , and is generally tubular in shape. Label 28 may be formed of polyvinyl chloride (PVC), for instance, preferably of at least about 2.7 mils thickness before being heat shrunk, but can possibly have a lesser thickness. Label 28 is preferably heat shrunk onto reaction vessel 14 without adhesive.
  • PVC polyvinyl chloride
  • Heat-shrink label 28 without adhesive, will aid in keeping the lateral outside of the inventive arrangement—and more particularly the outside of reaction vessel 14 —from becoming uncomfortably hot or uncomfortably cold. If adhesive is used, the thermal isolative quality of the label drops considerably. The thickness of the label and lack of adhesive for affixing the label aids in providing robust thermal isolation from the heat or cold generated within the reaction vessel.
  • the lateral outside of the inventive arrangement will stay within a comfortable temperature range of below about 120 F., and more preferably below about 115 F., by (1) applying a heat-shrink label 28 from about 2.0 to 2.7 mils thick PVC, without using adhesive; and (2) forming the lateral outside of reaction vessel 14 with 30- to 60-mil thick high-impact polystyrene, by way of example.
  • Materials other than high-impact polystyrene, which apparently has a substantial content of rubber so as to reduce thermal conductivity, can be used for the lateral outside of the reaction vessel, as will be apparent to those of ordinary skill in the art.
  • a solid reactant 20 ( FIG. 1 ) of 148 grams calcium chloride (CaCl 2 ) is mixed with 140 grams of water as liquid reactant 18 ( FIG. 1 )
  • the temperature of 6.5 ounces of liquid beverage within container 12 will reach 140 F. (i.e., 140 degrees Fahrenheit) typically within a brief period of time (e.g., 60 seconds). This represents a temperature change of about 70 degrees from a normal ambient temperature of 70 F.
  • the calcium chloride reactant may that identified as BRINERS Choice Anhydrous 94-97% Calcium Chloride Mini-Pellets, available from Dow Chemical Company of Midland, Mich.
