Description

Packaging for change before opening the temperature of the product stored in it

Technical field

The invention relates to the food industry, and more particularly to packaging for such objects that must be heated or cooled to the required temperature before use or use.

Prior art

The prior art various packaging designs are equipped with means that provide either heating the product stored in them to a predetermined temperature as a result of an exothermic reaction, or cooling the product stored in them to a predetermined temperature as a result of an endothermic reaction.

So known packaging for changing before opening the temperature of the product stored in it, containing a cylindrical body with a heat-insulating coating on the outer side surface and the bottom with the central part protruding into the body, a sealed cylindrical container for the stored product, which is installed coaxially inside the body close to the protruding inside the case the central part of its bottom and with the formation of an annular cavity between its outer side surface and the inner side surface of the housing, the lower part of the annular cavity is filled with reagent in the solid state, and in the upper portion of the annular cavity located chamber of elastic material, for example plastic, filled with the liquid reagent. On top of the annular cavity is closed by an annular cap hermetically connected along its outer contour with the body, and along the inner circuit with a container, while between the annular cap and the chamber made of elastic material ring gasket made of elastic material. The annular lid is provided with two dents for punching, and the top of the container with a shutter (see US-A-Ns 5542418, 1996).

The main disadvantage of the packaging described above for changing the temperature of the product stored in it before opening it is that it does not provide high efficiency in using the heat released as a result of the exothermic reaction, since heat is supplied to the container with the stored product only through its side surface and is accompanied by this large heat loss through the bottom of the housing, where there is no thermal insulation. In addition, the gases released during the exothermic reaction, rising to the upper part of the annular cavity, create a gas layer between the reactants, which slows down the process of mixing the reactants. This leads to a decrease in the maximum reaction temperature. It should also be noted that the presence of an annular gasket made of elastic material does not exclude the possibility that high-pressure products of exothermic reaction can get onto the upper surface of the container, which creates additional inconvenience when using the package.

Also known is a package for changing the temperature of the product stored in it before opening it, taken as a prototype and containing an upper removable cover, a heat-insulating body and a thermal module with an activator, including a piercing element, mounted on a flexible and convex outward central part of the bottom of the thermal module body. Inside the case of the thermal module are located: a container for the stored product, hermetically connected to it around the entire perimeter of its upper part, a reagent in the solid state and a section for reagents in the liquid state, containing a closed cylindrical chamber with a protrusion in its upper part, which secures the section to be fixed relative to the bottom of the container for the stored product. In addition, the closed chamber is provided in its lower part with an annular flange and radially isolated channels isolated from its internal cavity. A closed chamber is filled with a reagent in a liquid state, made of material, capable of puncturing, and is installed with the possibility of interaction with the pointed end of the piercing element of the activator of the thermal module when it is started. For this, the annular flange of the section is located on the inner surface of the bottom of the thermal module housing, and the section of the bottom of the closed chamber located opposite the pointed end of the piercing element is concave into the closed chamber with the formation of a cavity that, through the above-mentioned radial channels, communicates with the compartment of the cavity of the housing of the thermal module filled with reagent in the solid state (patent US-A-N ° 3970068, 1976, Fig. 8.9).

Taken as a prototype packaging for changes before opening the temperature of the product stored in it has the following disadvantages:

- it is not convenient to use, because to start the activator of the thermal module it is necessary, firstly, to turn the package upside down, secondly, to remove the safety cover located from the bottom, and thirdly, to destroy (puncture) the piercing element of the bottom of a closed cylindrical chamber filled the reagent in a liquid state, by applying the axial force to the convex flexible portion of the bottom of the housing of the thermal module;

- it is characterized by significant heat losses during the course of the exothermic reaction, since the reagents are mixed near the bottom of the body of the thermal module, in other words, where there is no thermal insulation;

- the section for the reagent in the liquid state has a complex structure (flange, radial channels), which leads to an increase in the cost of packaging.

In addition, in the known packaging there are no means providing a decrease in the peak value of the pressure of the vapor-gas mixture in the cavity of the housing of the thermal module in the course of the exothermic reaction. In other words, to the material of the container for the stored product and the thermal housing made at the same time The module of the known packaging has increased demands in terms of mechanical strength. This circumstance also leads to a rise in the cost of packaging.

Other advantages of the proposed packaging will become apparent from the following description.

The invention is further illustrated by specific examples, which, however, are not the only possible, but clearly demonstrate the ability to achieve the above set of essential features of the required technical result.

Disclosure of invention

The package for changing, before opening the temperature of the product stored in it, contains a heat-insulating casing 1 with a removable cover 2, a thermal module 3, which is placed inside the heat-insulating casing 1 (preferably coaxially to it), a container 4 for the stored product, and an activator of the thermal module 3, including holder 5 and at least one piercing element b (figure 1). The heat-insulating casing 1 is made in the form of a glass with a flat or concave bottom 7 of moisture-proof, lightweight, shock- and bending-resistant material with low heat conductivity and heat resistance not lower than 200 ⁰ C, for example, foamed polystyrene. The side wall of the heat-insulating housing 1 can be made of any shape: cylindrical, conical, barrel-shaped, etc., but with the possibility of flexing, it is preferable to flex elastically when a user applies a radially directed external load to it.

To improve the usability of the package, the insulating body 1 can be made with a side handle, in particular removable (not shown in the drawings).

The thermal module 3 includes a housing 8 of the thermal module, in the cavity of which there is a closed (sealed) chamber 9, designed to accommodate the reagent 10 in it in a liquid state, for example water, and reagent 11 in the solid state (in the form of granules, powder).

In a preferred embodiment of the invention, the thermal module casing 8 is made axisymmetric with respect to the axis of the package 12 and in the form of a hollow truncated cone with a smaller base facing down, which is the bottom of the thermal module casing 8. In principle, the housing of the thermal module may also have a different shape, for example, the shape of a straight circular cylinder, as in the prototype. An annular bead 13 is made on the outer side surface of the housing 8 of the thermal module, which is flush with the upper end of the side wall of the housing 8 of the thermal module (in other words, the large base of the truncated cone, Figs. 1 and 2). On the side wall of the housing 8 of the thermal module are made located along its generatrix and at the same angular distance from each other (in other words, uniformly around the circumference) of the recess 14 in the form of grooves having (in a preferred embodiment of the invention) the shape of a section of the conical surface (base 15 which in the plane jcna of the housing 8 of the thermal module in Fig. 2 is shown by a dashed line) with the vertex pointing upward and axis 16 parallel to the packaging axis 12. The length of the recesses 14, at least 3%, is less than the length of the generatrix of the outer side surface of the housing 8 of the thermal module. It should be noted here that the recesses 14 must be made, at least in the sections of the side wall of the housing 8 of the thermal module, located opposite the closed chamber 9, while the recesses 14 in the form of grooves can be made in the form of sections of any (circular, parabolic, etc. (p.) a cylindrical surface whose axis is at an acute angle to axis 12, exceeding half the angle at the apex of the conical side wall of the housing 8 of the thermal module.

The number of grooves 14 in the form of grooves should preferably be even: 4, 6.

The housing 8 of the thermal module can be made of polyethylene, PET (recycled polyethylene), as well as aluminum used in the food industry. In the case of housing 8 thermal It is advisable for a module made of polymer material to have at least its inner surface folded.

The closed chamber 9 is made of a punctureable film of polymeric material, for example polyethylene, and is placed in the cavity of the thermal module body 8 with a minimum gap between the parts of its outer surface and the corresponding parts of the inner surfaces of the bottom of all the recesses 14 (in the preferred embodiment of the invention, to them). In other words, with the above even (4, 6) number of recesses 14, the closed chamber 9, filled with liquid reagent 10, is secured in the transverse direction when exposed to loads radially directed and destroying the walls of the chamber 9. In a preferred embodiment of the invention, at least one through hole 17 with a diameter of 3-10 mm is made in the upper part of the side wall of the housing 8 of the thermal module. Moreover, on the outside of the side wall of the housing 8 of the thermal module, the holes 17 are closed with the corresponding plates 18, preferably of paper with a sufficiently high porosity (density not exceeding 60 g / m ² ). Opposite each through hole 9 in the cavity between the heat-insulating casing 1 and the casing 8 of the thermal module are placed, for example, containers 19 (bags, sachets, etc.) made of gas-permeable material filled with a sorbent material are glued to the inner surface of the side wall of the heat-insulating casing 1 vapors and gases released during the interaction of reagents 10 and 11 (activated carbon, silica gel, etc.). In a preferred embodiment of the invention (FIGS. 1 and 2), the through holes 17 are made in the bottom of the groove-shaped recesses 14, which allows to reduce the distance between the side walls of the heat-insulating housing 1 and the housing 8 of the thermal module, and therefore increase the fraction of the useful volume of the cavity of the heat-insulating housing 1 .

The container 4 for the stored product is made, in a preferred embodiment of the invention, in the form of a hollow truncated cone with a large base facing upwards, along the perimeter of which is made flange 20. The container 4 is placed in the cavity of the housing 8 of the thermal module, while its flange 20 is supported by the end of the upper part of the housing 8 of the thermal module, and the edges of the flange 20 are rolled along the annular collar 13. Thus, the container 4 around the entire perimeter of the larger base is hermetically sealed connected to the upper part of the housing 8 of the thermal module. The closed chamber 9 is either located close to the outer surface of the bottom of the container 4, or is separated from it by a layer of reagent 11.

The housing 8 of the thermal module with the reagent 11 placed in its cavity, the closed chamber 9 with the reagent 10, and also the container 4, which is hermetically connected to the upper part of the housing 8 of the thermal module, is installed inside the heat-insulating housing 1 and fixed relative to it, for example, by placing the annular flange 13 of the flange 20 in the corresponding annular groove made in the upper part of the inner surface of the side wall of the insulating body 1 (Fig. 1).

The holder 5 (Figs. 1, 3 and 4) is made of an annular shape with at least one elastically deformable section with weakened mechanical strength, for example, with straight thin jumpers 21 and protrusions 22 inward (to the axis 12), the number of which is equal to the number (preferably two) piercing elements 6, made, for example, in the form of steel, thin (with a diameter of 0.5 - 2.0 mm) rods (needles) pointed on one side. Each piercing element 6 is placed in a corresponding groove made on the surface of the corresponding protrusion 22 and is fixed (fixedly fixed) using the corresponding lining 23 with the locking protrusions 24, which are inserted into the corresponding holes 25 made in each protrusion 22. The protrusions 22 are opposite each other friend and opposite the corresponding recess 14 on the housing 8 of the thermal module (Fig. 1, 3, 5 and 6), while the piercing elements b are located opposite the closed cavity 9 on a straight line passing through 12 of the package and respective external load application direction P (FIG. 6). In principle, the piercing elements 6 can be fixed on a holder that does not contain protrusions 22. In particular, the piercing elements 6 can simply be pressed into the material of the holder when it is molded. Instead of rectilinear jumpers 21 can be used jumpers 21.1 arcuate (Fig. 7) or jumpers 21.2 V-shaped (Fig. 8). Jumpers 21, 21.1 and 21.2 are made either integrally with other elements of the holder 5 (Figs. 3 and 7), or in the form of corresponding inserts from another, for example, less mechanically strong material (Fig. 8).

The holder 5 may have other design, for example in the form of a hoop with a faceted external and / or internal surface.

The activator of the thermal module 3 (Fig. 1) is fixed on the inner surface of the side wall of the heat-insulating body 1 so that the ends of the piercing elements 6 are opposite (preferably touched) sections of the outer surface of their respective recesses 14, opposite which are the above-mentioned sections of their inner surfaces, relative to which, with a minimum clearance or close to them, sections of the outer surface of the closed chamber 9 are located. In other words, the pointed ends of the piercing element 6 located opposite the closed chamber 9 and at a distance less than the maximum value of the deflection of the side wall of the heat insulating housing 1. To consolidate the activator on the inner conical surface of the side wall of the heat insulating housing 1 formed with an annular groove 26 in diameter allowing installation therein holder 5 with the desired interference fit. In the case of a heat-insulating casing 1 with a side wall having a cylindrical shape of the inner surface, the fixing of the holder 5 in the cavity of the heat-insulating casing 1 at a predetermined distance from its bottom 7 is achieved either by performing an annular collar on the inner surface of the side wall of the heat-insulating casing, or supporting ribs 27 located evenly around the circumference and along the generatrix of the inner surface (Fig. 9). In this case, the grooves 28 corresponding to the support ribs 27 are made on the outer surface of the holder 5, and the installation of elastically deformable (due to the presence of jumpers 21, 21.1 and 21.2) of the holder 5 with the required interference fit is provided by the selection of the appropriate ratio between the diameter of the holder 5 and the diameter of the inner cavity of the insulating body 1.

However, the above-described options for fixing the activator of the thermal module on the heat-insulating casing 1 are not exhaustive for the proposed technical solution, which makes it possible to fix the activator on other packaging elements, for example, on the case of the thermal module. So in FIG. 10 and 11 of the embodiment of the package for changing the temperature of the product stored in it before opening it, the heat-insulating casing 1.1 is made, for example, with a cylindrical side wall truncated in the lower part onto a cone to reduce the thickness of the material of the heat-insulating casing 1.1 in the interface zone of its side wall with the bottom 7.1 in which a blind hole 29 is made.

The housing of the thermal module 3.1 is made axisymmetric with respect to the axis of the package 12 and includes the upper part 30 and the lower part 31 made in the preferred embodiment at the same time. The upper part 30 of the housing of the thermal module 3.1 is made in the form of a hollow truncated cone with a large base facing upward and an annular bore 13.1 intended (similar to that described above) for the tight connection (in particular by rolling) of the housing of the thermal module with the container 4 for the stored product. The lower part 31 is made of a cylindrical shape with a bottom 32 and is mated on top with a smaller base of the truncated cone of the upper part 30. At least two (preferably four, six) recesses 14.1 are arranged uniformly around the circumference in the form of holes having in a preferred embodiment, the shape of the surface of rotation of the arc of a second-order curve, such as a circle. At the same time (similar to the above-described embodiment of the recesses 14 in the form of grooves), a closed chamber 9 with a reagent 10 in the liquid state is placed in the cavity of the lower part 31 opposite the recesses 14.1 and with a minimum gap between the sections of its outer surface and the corresponding sections of the inner surfaces of all the recesses 14.1 (in the preferred embodiment of the invention, close to them). In addition, the thermal module 3.1 contains nozzles 33 in the form of a cylindrical cup, tightly covering the lower part of the housing 31, with the possibility of axial movement relative to it and spring-loaded from below from the side of its bottom, for example a four-leaf spring 34, which is installed in the hole 29. Near the bottom 32 the lower part 31 has a radial through hole 35, and opposite it, on the side wall of the nozzle 33 (along its generatrix) is the corrugation 36 that is open only from below, forming a channel through the outer surface of the side wall of the lower part 31, through which, and then through the opening 35, the cavity of the nozzle 33 communicates with the cavity of the thermal module 3.1. In addition, on the side walls of the lower part 31 of the housing of the thermal module 3.1 and the nozzle 33 is made at least one pair of holes 37 and 38 arranged to combine them each other in the lowermost position, the nozzle 33. On top of the container 4 for the stored product is equipped with a widely used in the food industry openable shutter 39, for example of aluminum foil with a tongue 40 for ease of removal before use on odyaschegosya in the container 4. The activator of the thermal module 3.1 contains a holder 5.1 and two piercing elements 6, which are also made as described above - in the form of thin (with a diameter of 0.5 - 2.0 mm) steel rods that are pointed on one side. The holder 5.1 is made of an elastically deformable material, mainly plastic, in the form of an open (cut) ring with two cantilevered identical arcuate pushers 41 located on its outer cylindrical surface, and with identical protrusions uniformly spaced around the inner cylindrical surface of the open ring 42, the number of which is equal to the number of recesses 14.1. In the holder 5.1, two through radially arranged and coaxial holes are made, each passing through a corresponding protrusion 42 from opposite pairs of protrusions 42. Each piercing element 6 is placed with the possibility of sliding longitudinal movement in the corresponding through radially located hole made in the holder 5.1, while the pointed ends of the piercing elements 6 are located opposite each other and on both sides of the lower part 31. The length of the piercing elements 6 is longer than the length of the above-mentioned through radially located holes at least by the distance between their pointed ends. In a preferred embodiment of the invention, the arcuate pushers 41 are arranged equidistant from the outer cylindrical surface of the open ring with the possibility (upon application of forces radially directed to the axis of the open ring) of their loose ends interacting with the non-pointed ends of the piercing elements protruding beyond the open ring 6. In a preferred embodiment of the invention, the arcuate pushers are rotated relative to each other by 180 °. The activator of the thermal module 3.1 is placed outside the lower part 31 of its body, while the protrusions 42 of the holder 5.1 are located in their respective recesses 14.1, are pressed to their bottom surface due to the elastic deformation forces of the open ring, and the pointed ends of the piercing elements 6 are located close to the surface corresponding recesses 14.1.

As already noted above, the material of the heat-insulating buildings 1 and 1.1 must be moisture-gas-tight, lightweight, shock and bending, have a sufficiently high heat resistance and low thermal conductivity. At the same time, in order to ensure the deflection necessary for the activation of the thermal module activator, in other words, the radial deformation of the side wall of the heat insulating body, the thickness of the side wall itself should not be large, since an increase in the thickness of the side wall will inevitably lead to an increase in the force applied by the user to actuate the thermal module, and, therefore, to create additional inconvenience when using the package. The proposed implementation of the thermal module with a protective gas-tight casing, and also other features of the present invention are illustrated by the following description and drawings: FIG. 12-19.

Packaging for change. Before opening the temperature of the product stored in it (Fig. 12) it contains a cylindrical heat-insulating casing 1.2 with an annular groove 43 from the bottom 7.2, the length of which is

1, 05 - 1, 5 times the thickness of the bottom 7.2. During transportation and storage of the package in the groove 43, the safety ring 43.1 shown in FIG. 12 dashed line.

The housing 8.1 of the thermal module is made in the form of a hollow truncated cone with the smaller base facing down, which is the bottom of the housing 8.1 of the thermal module. An annular bead 13 is made on the outer side surface of the housing 8.1 of the thermal module, which is flush with the upper end of its side wall. On the side (conical) wall of the housing 8.1 of the thermal module there are one or two (according to the number of piercing elements 6.1) recesses 14.1 in the form of holes having, in the preferred embodiment, the shape of the surface of rotation of the arc of a second-order curve. Through holes 17 with a diameter of 3-10 mm are made in the upper part of the side wall of the housing 8.1 of the thermal module, while on the outside of the side wall of the housing 8.1 of the thermal module, the holes 17 are closed with corresponding plates 18 of paper with a density not exceeding 60 g / m ² .

A container 4 for a stored product is placed in the cavity of the housing 8.1 of the thermal module, which (similar to the one described above) is made in the form of a hollow truncated cone with a large base facing upwards, along the perimeter of which is made a flange 20. The smaller base of the truncated cone is the bottom of the container 4 , on the outside of which is placed, for example, mounted, a frame 44 for a closed chamber 9 with a reagent 10 in a liquid state. The frame 44 is made, for example, in the form of a "squirrel wheel", namely: in the form of two ring elements: the upper 45 with a tapered groove 46 for mounting the frame 44 with an interference fit on the container 4 and the lower 47, interconnected by vertical jumpers 48 located along the circumference of the annular elements 45 and 47. The frame 44 can be made monolithic of polymeric materials or of individual parts interconnected by known means. The frame 44 provides a fixation of the position of the closed chamber 9 relative to the housing 8.1 of the thermal module both in the axial (in the direction of the axis 12) and in the radial directions, not only during transportation of the package, but also in the process of starting the thermal module, as a result of which the interaction of the closed chamber 9 with piercing elements 6.1, it is destroyed with the subsequent interaction of reagents 10 and 11. To ensure the convenience of using the package, the thermal module contains a protective gas-tight casing 49, which The second is located between the thermally insulating housing 1.2 and the housing 8.1 of the thermal module. Protective gas - waterproof casing 49 is made in the form of a cylindrical thin-walled glass with a bottom. As the material for the manufacture of protective gas-tight casing 49 can be used aluminum, polyethylene, etc. In the case of using polymeric materials, in a preferred embodiment, the inner surface of the protective gas-tight casing 49 is made foil. In the upper part, the protective gas-tight casing 49 is hermetically connected to the flange 20, for example, rolled (Fig. 12).

In FIG. 13 shows another embodiment of a sealed rolled connection of the container 4 for the stored product with the housing 8.1 of the thermal module and with a protective gas-tight casing 49, which in the present embodiment is made with an annular collar 50 on its outer surface of the side wall flush with its upper end. In this case, the edges of the flange 20 are rolled along the flanges 13 and 50 closely spaced. In principle, the tight connection of the container 4, the housing 8.1 of the thermal module and its protective gas-tight casing 49 can be carried out using glue, heat sealing, soldering, as well as other known in food industry means and methods. In a preferred embodiment, the inner the surface of the side wall of the protective gas-tight casing 49 is a layer 51 of gas-vapor-sorption material. Layer 51 is placed opposite the openings 17, while containers 19 of gas-permeable material filled with a substance that also, like the material of layer 51, sorb vapors and gases released during the interaction of reagents 10 and 11 are additionally placed on the bottom of the protective gas-tight casing 49 thermal module consists of a ring-shaped holder 5.2 made of elastically deformable material integral with the piercing elements 6.1 (Figs. 14 and 15). The piercing elements 6.1 have an elongated triangular shape and are formed by extruding from the original continuous tape material of the holder 5.2.

The holder 5.2 is made either in the form of an open ring (Figs. 14 and 15), or in the form of two identical half rings 52 and 53 made of an elastically deformable metal strip and interconnected by V-shaped or arched inserts 54 and 54.1, respectively (Fig. 16 and 17). The activator of the thermal module is placed on the inner surface of the side wall of the protective gas-tight casing 49 between the two annular folds 55, while the piercing elements 6.1 abut (located closely) to the bottom of the corresponding recess 14.1. Additional fixation of the activator of the thermal module can be achieved due to the elastic deformation forces of the ring-shaped holder 5.2 itself, providing it is pressed against the inner surface of the side wall of the protective gas-tight casing 49. In this modification of the package, the holder 5 described above can be used. Similarly, the holder 5.2 can be used in the modification of the packaging shown in figure 1. The removable cover 2, in the preferred embodiment, is made with tear-off before its removal of the annular locking element 56, which is widely used in food packaging. It should be noted that the use of a protective gas-tight casing 49, in principle, allows you to perform a heat-insulating casing 1.2 with a hole in the bottom. However, this will inevitably lead to the underutilization of thermal effect (heating or cooling) resulting from the interaction of reagents 10 and 11.

Protective gas-tight casing 49 can be located either close to the inner surface of the insulating casing 1.2, or with a gap relative to it ³ (Fig. 18 and 19). The housing 8 of the thermal module (in contrast to that shown in Figs. 1 and 2) is made with a cylindrical section 57, which serves to install a tight fit (or on a thread) of a protective gas-tight casing 49. The activator of the thermal module in the modification shown in FIG. 18 and 19 comprises a holder in the form of a ring 58 located at the bottom of a protective gas-tight casing 49 with two (or one) uprights located opposite each other in a diametrical plane, which is a plane of symmetry of two recesses 14 located opposite each other.

Each rack includes two parallel to each other flexible rods 59, the lower ends of which are connected to the ring 58 either directly (made integral with it, for example by molding), or using the lower bridge 60 connecting the lower ends of the rods 59 with each other and provided with mounting tabs 61 . Installation ledges

61 are located in the corresponding holes provided in the ring 58. The upper ends of the rods 59 are interconnected by an upper jumper

62 parallel to the lower jumper 60. In the jumper 62, for example, the piercing elements 6 are fixedly fixed, such as pressed in. In addition, in a preferred embodiment of the invention, each upper jumper 62 is provided with two flexible strips (petals) 63 that interact with those located on both sides of the corresponding depression'14 with sections of the outer surface of the housing 8 of the thermal module. Flexible rods 59 in conjunction with jumpers 60 and

62 form a parallelogram mechanism, while the flexible rods 59 are inclined in the opposite direction from the axis 12, i.e. at an angle φ to the plane of the ring 58. On a portion of the outer surface made of sheet material of the tear-off shutter 39, thermal paint 64 is applied with an irreversible color change when it is heated to the appropriate temperature. Packaging for change before opening the temperature of the product stored in it operates as follows. In the initial state, the stored product (water, tea, broth, drink, etc.) is placed in the cavity of the container 4 and, depending on the specific storage conditions, is closed by an openable shutter 39 with a tongue 40 and / or a removable lid 2. Reagent 10 in a liquid state (mainly water) is in a closed (sealed) chamber 9, which is made of material capable of destruction (puncturing) when exposed to at least one, located opposite each other and from two opposite sides relative to the closed chamber 9 piercing elements 6 or 6.1 (Fig. 12). A closed chamber 9 is placed in the cavity of the housing 8 or in the lower part 31 (Fig. 10, 11) of the thermal module with a minimum clearance (preferably close to) to the parts of the inner surface of the recesses 14 or 14.1 (Fig. 10) corresponding to their bottom. The closed chamber 9 can be located close to the outer surface of the bottom of the container 4 (Fig. 12) or separated from it by a layer of reagent 11 in the solid state (for example, a mixture of powders of active metals - zinc, magnesium with an anhydrous salt of an inactive metal - copper sulfate), which also fills the rest of the lower cavity of the housing 8 of the thermal module. The closed chamber 9 may also be in a special frame 44 (Fig. 12).

The health of the thermal module can be controlled by the color of the thermal paint 64 with an irreversible color change (for example, when it is heated to a temperature exceeding 70 ⁰ C) applied to the portion of the outer surface of the openable shutter 39. So, if the thermal paint 64 is based on ammonium cobalt monohydrate, then its bright pink color indicates that the thermal module is working. If the thermal paint 64 is blue, then, therefore, the thermal module is faulty due to, for example, accidental operation during storage, transportation.

The serviceable thermal module is launched by the user applying radially to the heat-insulating casing 1 (or similarly to the heat-insulating casing 1.1 and 1.2) directional external load P (Fig. 6). In this case, the direction of application of the external load coincides with the straight line along which the piercing elements 6 (or 6.1) are located with pointed ends facing each other. In order to ensure that the external load P is applied strictly in the required direction, on the external surface of the side wall of the above-mentioned heat-insulating bodies are marked (not shown in the drawings) corresponding signs for users, for example, stickers.

It should be noted here that the most complete use of the internal volume of the heat insulating casing is ensured in the case of the location of the activator of the thermal module in its lower part. However, due to the close location of the bottom 7, the lower part of the heat-insulating body 1 is characterized by a higher, high radial compression stiffness. To ensure greater deflection deformation of the lower part of the heat insulating bodies mentioned above, the side wall of these buildings is either truncated in the lower part to a cone (Fig. 10) or with an annular groove 43 (Fig. 12). In the latter case, before starting the thermal module, the safety ring installed in the groove 43 (against accidental activation of the thermal module activator) is removed from the ring 43.1.

As a result of the application of a compressive external load P to the heat-insulating body 1, it deforms in the form of a deflection, as a result of which the external load applied by the user to the heat-insulating body is transferred to the holder 5. First, the elastic deformation of the holder 5 takes place due to the presence of elastically deformable sections (jumpers 21, 21.1 or 21.2) with weakened (compared to the rest of the holder 5) mechanical strength, and then (after reaching the applied external load P, and therefore Nogo its deflection of the heat insulating housing 1, and interacting with the inner surface of the lateral wall of the holder 5, a predetermined threshold) is destroyed, at least one of the aforementioned webs. After the destruction of at least one of the jumpers 21 (21.1 or 21.2), the holder 5 stops exert a significant influence on the deformation of the heat-insulating body 1, and therefore, the external load applied to it is transmitted through the piercing elements 6 to the bottom of the recesses 14. Since the closed chamber 9 is located close to or almost close (with a small gap) to the parts of the inner surface of the recesses 14 in the form of grooves or their modifications 14.1 in the form of holes, the interaction of the pointed ends of the calcined ^'ayuschyh elements 6 with a closed chamber 9 will occur almost immediately after piercing of steno to the housing 8 of the thermal module located at the bottom of the recesses 14 (14.1). It should be noted here, when molding the body 8 of the thermal module, due to the "drawing" of the material, the wall thickness in the bottom region of the recesses 14 (14.1) is minimal. Thus, the execution of the housing 8 of the thermal module with recesses 14 in the form of grooves or recesses 14.1 in the form of holes not only ensures: a) fixing the position of the closed chamber 9 in the radial direction when interacting with the piercing elements 6 or 6.1, and b) reducing the magnitude of the deflection of the insulating case 1, necessary for piercing the closed chamber 9, but also allows to reduce the amount of compressive external load P necessary for piercing the wall of the housing 8 of the thermal module.

After piercing the closed chamber 9, the reagent 10 in a liquid state starts to flow out of the closed chamber 9. The reagents 10 and 11 are mixed. As a result of mixing the reagents 10 and 11, either an exothermic or endothermic reaction occurs depending on their specific chemical composition.

In the case of an exothermic reaction, intense heat and water vapor are released. Intensive heat release leads to rapid heating of the product stored in the container ^~ 4 due to heat transfer. To eliminate the negative consequences associated with a large amount of steam released in a short time, a number of products are used in the proposed packaging that promote both its condensation and its sorption. So, the execution of the housing 8 of the thermal module either from metal (aluminum), or their foil polymer material allows you to intensify the process of condensation of water vapor inside the housing 8 of the thermal module (on its inner wall). Uncondensed water vapor passing through the through holes 17 is partially sorbed in the porous material of the plates 18. Water vapor passing through the plates 18 is finally sorbed by the material in the containers 19, as well as in the material of the layer 51 (Fig. 12). Thus, due to condensation and sorption of water vapor, the maximum overpressure in the packaging cavity during the course of the exothermic reaction is significantly reduced. To exclude, during the exothermic reaction, a sharp increase in pressure inside the case of the thermal module 3.1 to a value exceeding the permissible value from the point of view of its mechanical strength, it is proposed to execute the thermal module with nozzle 33 (Fig. 10), while the cavity of the thermal module communicates with the nozzle cavity through the channel formed by the corrugation 36 and the hole 35. As a result, if the pressure in the cavity of the housing of the thermal module 3.1, and therefore in the cavity communicating with it, the nozzle 33 exceeds the air pressure in the cavity between the heat-insulating casing 1.1 and the casing of the thermal module 3.1, the nozzles 33 will begin to move downward, compressing the spring 34. With a further increase in the above differential pressure of the nozzles 33 will move down until the hole 38 is not aligned with the hole 37. Partial "bleeding" water vapor into the cavity between the heat-insulating casing 1.1 and the casing of the thermal module 3.1 until the pressure of water vapor in the zone of the exothermic reaction reaches the maximum permissible . In other words, nozzles 33 and openings 37 and 38 function as a safety gas valve.

The work of the proposed packaging when cooling the product stored in the container 4 is no different from the one described above. In this case, gas sorbing elements can be used to eliminate the unpleasant odor arising from the endothermic reaction. At the end of the reaction between reagents 10 and 11, the shutter 39 is removed. As a result, the user has access to a stored product, heated or cooled to a predetermined temperature.

As noted above, when starting the thermal packaging module shown in FIG. 10 and 11, under the influence of an external load, a deflection of the heat-insulating casing 1.1 occurs. To reduce the likelihood of an accidental start of the thermal module, the arcuate pushers 41 are located with a gap relative to the inner surface of the side wall of the heat insulating body 1.1. When the magnitude of the deflection of the insulating body 1.1 exceeds the value of the gap indicated above, the arcuate pushers 41 will begin to bend towards the holder 5.1 and simultaneously act on the non-pointed ends of the piercing elements 6. Since the piercing elements 6 are placed in their respective through radial holes on the sliding nozzle, it is applied by the user the external load will be freely transmitted to the bottom of the recesses 14.1, as a result of which their walls are punctured.

When using the proposed packaging protective gas-tight casing 49 (Fig. 12, 18), the launch of the thermal module is carried out similarly as described above. The use of the frame 44 for the closed chamber 9 provides only a more reliable fixation of the closed chamber 9, but does not affect the process of starting the thermal module.

Regarding the operation of the activator shown in FIG. 18 and 19, when the rounded part of the upper jumpers 62 is exposed to an external load, each pair of flexible rods 59 rotates at the same time to increase the angle φ. In this case, the piercing elements 6 remain parallel to the plane of the ring 58, which is the main property of the parallelogram mechanism used in this case. Flexible strips 63 reduce the likelihood of accidentally starting the thermal module during shipping.

In principle, one flexible rod can be used in the claimed package instead of a pair of flexible rods 59. However, this simplification of the packaging can lead to a deterioration in its technical and operational parameters. Industrial applicability

The industrial applicability of the proposed invention is confirmed by the possibility of its implementation using well-known materials and technological processes widely used in the food industry.
