Definitions

  • the invention relates the food industry, more specifically to packages for such objects that should be heated up or cooled down to a required temperature prior to consumption or use.
  • packages are known from the prior art, said packages being provided with means which allow the heating of a stored product up to a predetermined temperature as a result of the course of the exothermic reaction, or the cooling of a stored product down to a predetermined temperature as a result of the course of the endothermic reaction.
  • a package for changing a stored product temperature prior to the opening thereof, said package comprising: a cylindrical case with a heat insulating coating at an external lateral surface and with a bottom having a central portion extending into the case; a sealed container for the stored product, said container being coaxially installed within the case closely to its bottom central portion extending into the case to form an annular cavity between its external lateral surface and an internal lateral surface of the case, wherein a lower portion of the annular cavity is filled with a solid reagent while a chamber of an elastic material, for example plastic, is located in an upper portion of the annular cavity and is filled with a liquid reagent.
  • annular cavity is closed at the top by an annular lid hermetically connected along its external contour to the case and along its internal contour - to the container, wherein an annular strip of an elastic material is placed between the annular lid and the elastic material chamber.
  • the annular lid is provided with two dents to perforate it while the upper portion of the container is provided with a closure (see US-A-5,542,418, 1996 ).
  • the basic disadvantage of said package for changing prior to the opening thereof consists in that it does not allow high effectiveness of using heat evolved as a result of the exothermic reaction because the heat supply to the container with the stored product takes place only via the lateral surface of the container and is accompanied with a large heat loss via the case bottom where the heat insulation is absent. Further, when gases evolved during the exothermic reaction ascend to the top of the annular cavity, they form a gas space between reagents, said gas space decelerating the process of mixing the reagents. This results in reduction of a maximum reaction temperature. It should be also noted that the presence of the elastic material strip does not exclude the ability of the high-temperature products of the exothermic reaction to arrive at the upper surface of the container, which generates additional problems and inconveniences in use of the package.
  • a package is also known for changing a stored product temperature prior to the opening thereof, said package being taken as a prototype and comprising: an upper detachable cap, a heat insulating body and a thermal module with an activator including a piercing member fastened on a central portion of a bottom of a thermal module case, said central portion being formed flexible and convex outwardly.
  • a thermal module case Arranged in a thermal module case are a stored product container hermetically connected thereto around an entire perimeter of own upper portion, a solid reagent, and a liquid reagent storage section comprising a closed cylindrical compartment with a protrusion in its upper portion, said protrusion providing the fixation of said section relative to a bottom of the stored product container.
  • the closed compartment in its lower portion is provided with an annular flange and radially arranged channels.
  • the closed compartment is filled with a liquid reagent, is formed of a material capable to be pierced, and is installed to interact with a tip of the activator of the thermal module in actuation thereof.
  • the annular flange of said section is arranged at an internal surface of the bottom of the thermal module case while a bottom portion arranged oppositely to the tip of the piercing member is concaved into the closed compartment to form a cavity in communication via said radial channels with a cell in the cavity of the thermal module case filled with the solid reagent (Patent US-A-3,970,068, 1976 , Figs. 8, 9).
  • the prior art package does not comprise means to provide reduction in a peak value of the gas-vapor mixture in the cavity of the thermal module case in the course of the endothermic reaction.
  • the increased requirements in part of the mechanical strength are imposed upon a material of the stored product container and the thermal module case integrated therewith.
  • the present invention is aimed at solution of the technical problem to improve the convenience in use of a package for changing a stored product temperature prior to the opening thereof at simultaneous increase of effectiveness of using the heat effect of a reagent reaction due to reduction in heat exchange with environment and also lowering of the requirements to the strength parameters of a stored product container and a thermal module case by lowering a peak value of a gas-vapor medium pressure in the course of the reaction.
  • a thermal module case are a stored product container hermetically connected thereto around an entire perimeter of own upper portion as well as a solid reagent and a closed compartment formed of a material capable to be pierced, containing a liquid reagent and installed to interact with the tip of the piercing member of the activator of the thermal module when the latter is driven, according to the invention, there are recesses formed at equal angular distances relative to each other in a sidewall of the thermal module case at least oppositely to the closed compartment arranged therein, wherein an internal surface area of each recess bottom is arranged at a minimum gap or closely to the closed compartment, the heat insulating body is formed with a bottom and a sidewall flexed at application of a radi
  • the advantage of the inventive package for changing a stored product temperature prior the opening thereof over the prototype consists in that an embodiment of the liquid reagent section without a flange and radial channels and simply in the form of the closed compartment allows not only simplification of the package design and therefore reduction of its cost but also placement of the thermal module activator not below but from the side of the closed compartment. As a result, the use of the packages becomes more convenient because it is not necessary now to turn it upside-down when the thermal module is driven.
  • thermo module activator to be annularly-shaped, installed coaxially with the thermal module case and capable of sensing an external load when the sidewall of the heat insulating body flexes and of displacing the piercing members installed on the holder in a radial direction when they are subjected to said external load, the tips of said members being in the vicinity of the closed compartment with the liquid reagent due to presence of recesses in the sidewall, makes it possible to drive the thermal module in a very simple manner, exactly, by flexing with hand fingers from one or two (depending upon a number of piercing members fastened on the holder) oppositely arranged sides of the sidewall of the heat insulating body for several millimeters (2 to 4 mm on average, as experiments have shown).
  • the recesses in the sidewall of the thermal module case arranged at least oppositely to the closed compartment arranged within the thermal module case, provide not only the possibility to drive the thermal module by small flexure of the sidewall of the heat insulating body but also to fix a position of the closed compartment with the liquid reagent when the piercing members act thereto.
  • An embodiment of the heat insulating body with the bottom makes it possible to decrease significantly heat exchange in a reaction zone with environment accompanied with a heat effect (heat evolution or absorption). This allows improvement in effectiveness of using the heat effect of the reacting reagents and therefore reduction in consumption thereof to obtain a required change of a stored product temperature.
  • the presence of the through openings in the side surface (in its upper portion) of the thermal module case, said openings being covered by plates of a porous material from the external side of the thermal module case, and also the presence of containers with sorbents allows essential decrease of a peak pressure value in the reaction zone and therefore lowering of the requirements to the strength parameters of the thermal module case, the heat insulating body and the protective gas-watertight housing.

  • the flexible rods 59 together with the crosspieces 60 and 62 form a parallelogram mechanism, wherein the flexible rods 59 are tilted oppositely to the axis 12, in other words, at an angle ⁇ to a plane of the ring 58.
  • a thermal paint 64 is applied to an external surface area of the discoverable closure 39 and has an irreversible color variation in heating up to a respective temperature.
  • the package for changing a stored product temperature prior to the opening thereof operates as follows.
  • a stored product water, tea, broth, drink, and so on
  • the liquid reagent 10 preferably water
  • the closes compartment 9 is placed in the cavity of the case 8 or in the lower portion 31 (Figs.
  • the closed compartment 9 can be arranged closely to the external surface of the bottom of the container 4 (Fig. 12) or separated therefrom by a layer of the solid reagent 11 (for example, a mixture of powders of active metals, such as zinc, magnesium, with a non-aqueous non-active metal salt, such as copper sulfate) that also fills all the residual lower portion of the cavity of the thermal module case 8.
  • the closed compartment 9 can be installed in the special mount 44 (Fig. 12).
  • the serviceability of the can be monitored by a color of the thermal paint 64 having an irreversible color variation (for example, in heating up to a temperature higher than 70 °C) and applied to an external surface area of the discoverable closure 39.
  • a color of the thermal paint 64 having an irreversible color variation (for example, in heating up to a temperature higher than 70 °C) and applied to an external surface area of the discoverable closure 39.
  • the thermal paint 64 is based on cobalt ammonia monohydrate, then, the bright pink color thereof attests the serviceability of the thermal module. If the thermal point 64 has the blue color, then, the thermal module is unserviceable, for example, because of a random actuation during storage or transportation.
  • the thermal module is driven by a user who applies a radially directed external load P (Fig. 6) to the heat insulating body 1 (or similarly to the heat insulating bodies 1.1 and 1.2). In doing so, a direction of applying the external load coincides with a straight line along which the piercing members 6 (or 6.1) having tips faced each other are arranged.
  • respective indicators for example labels (not shown in the drawings) for users are applied on the external surfaces of said heat insulating bodies.
  • the thermal module activator is in the lower portion of said body.
  • the lower portion of the heat insulating body 1 is characterized by a higher radial compression rigidity.
  • the sidewall of said bodies either is cone-truncated in its lower portion (Fig. 10) or has the annular turned groove 43 (Fig. 12). In the latter case, the safety ring 43.1 (which protects from a random actuation of the thermal module activator) installed within the turned groove 43 is removed.
  • the holder 5 After destruction of at least one of the crossbars 21 (21.1 or 21.2), the holder 5 stops to have a significant influence upon the strain of the heat insulating body 1, and therefore the external load applied thereto is transmitted via the piercing members 6 to the bottoms of the recesses 14. Since the closed compartment 9 is arranged closely or practically closely (with a small gap) to the internal surface area of the recesses 14 formed as grooves or their modifications 14.1 formed as holes, then interaction of the tips of the piercing members 6 with the closed compartment 9 will take place practically immediately after piercing the walls of the thermal module case 8 by said members, said walls being in the bottoms of the recesses 14 (14.1).
  • thermal module case 8 of either a metal (aluminum) or a foiled polymeric material allows intensification of the steam condensation process within the thermal module case 8 (at the internal wall thereof). When non-condensed steam passes via the through openings 17, it is partial sorption thereof in a porous material of the plates 18.
  • the final sorption of the steam passed via the plates 18 is performed by a material present in the containers 19 as well by a material of the layer 51 (Fig. 12).
  • a value of a maximum excessive pressure within the cavity of the package is essentially reduced due to compensation and sorption of the steam in the course of the exothermic reaction.
  • the thermal module With the casing head 33 (Fig. 10), wherein the cavity of the thermal module is in communication with a cavity of the casing head via a channel formed by the corrugation 36 and the opening 35.
  • the casing head 33 starts to move downwardly thereby to compress the spring 34.
  • the arched pushers 41 are positioned with a gap relative to the internal surface of the sidewall of the heat insulating body 1.1. If a flexure value of the heat insulating body 1.1 is larger than said gap, the arched pushers will begin to flex towards the holder 5.1 and simultaneously act to non-pointed faces of the piercing members 6.
  • the thermal module is driven similarly to that described above.
  • Use of the mount 44 for the closed compartment 9 provides only the more reliable fixation of the closed compartment 9.
