Useful for preparation of packaged products which can be rapidly heated using an integrated heating module.
Description
- The present invention relates to a self-heatable container.
- The field of the invention is that of the preparation of containers intended to contain food products, especially beverages, soups and the like, which can be consumed at a temperature greater than room temperature and in any place, particularly when specific heating means are not available.
- Several types of self-heatable containers provided with incorporated means for the local generation of heat in order to increase the temperature of a beverage up to a certain value are known. Among the mentioned types are that described in patent WO 03/064283 and other similar patents.
- The models of containers provided with incorporated heating means which have been disclosed have certain drawbacks, such as their complex structure demanding complicated and therefore expensive manufacturing processes. In addition, some types described in patents have a questionable suitability, given the technical difficulty in maintaining the constitutive parts thereof hermetically joined.
- In other cases, the functional and shape design of the proposed containers is scarcely suitable for the intended purpose.
- Therefore, it is desirable to have a container provided with its own heating means, which has a suitable structure and is easy to use and which reaches temperature levels suitable for the type of product contained relatively quickly.
- The invention relates to a container with a simple structure (with a minimum of component parts) and reasonably simple construction, essentially formed by a body containing the product, conventionally closed, and by an incorporated heating device which works by the likewise known principle of the exothermic reaction of two chemical products which are contacted prior to the consumption of the beverage of interest. This process takes place with safety and efficiency as a result of the design of the parts forming the container and the associated device thereof.
- To facilitate the explanation, several drawings are attached to the present description, in which a case of embodiment of a self-heatable container, according to the principles of the claims, has been depicted by way of an illustrative and non-limiting example.
-
FIG. 1 is an exploded view of the components forming essential container parts of the new container, depicted in the relative position of their coupling. -
FIG. 2 is a view of a housing which can be operated to cause the heating process of the container and with two associated elements. -
FIG. 3 shows the housing and its associated elements coupled to one of the containers forming the new container, which, in turn, is associated with another of the containers. -
FIG. 4 shows the operation of the device causing the heating of one of the containers and the latter, in turn, that of the beverage contained in the other container of the container. -
FIG. 5 indicates the normal position of the container with its content heated and ready for its consumption. -
FIGS. 6 and 7 are sectional details of the functional housing included in the container. - Constitution of the container. The
body 1 contains the product, such as a beverage, soup or the like, intended for its consumption, optionally, once heated by the incorporated means. - Said
body 1 can have any regular shape, such as a cylindrical shape, according to the attached drawings, and is made of a metallic material of a suitable thickness. In its upper part it has a flange 2 intended to receive adiscoid lid 3 provided with conventional opening means and fixed by a peripheral crimp 4. - In its lower part, the
body 1 has anarea 5 with an optionally decreasing diameter and followed by acylindrical area 6 with a smaller diameter provided with aflange 7 at its end for placing aclosing lid 8, similar tolid 3, finally fixed by ahermetic crimp 24. - The
container 9 consists of a cylindrical body having in its mouth a projectingflange 9′, therefore saidcomponent 9 is supported in thelower flange 7 of thefirst container 1. - The
component 10 in the form of a housing is a cylindrical body of a small height with respect to its diameter, made of a plastic material which, in itscylindrical side part 11, has a considerable resistance, whereas itsbase 12, of a reduced thickness, is flexible in its central part, defining a dome in the inner face of which there is theprojection 13. The latter has the form of a prism with a square section, withcuts 14 in its faces like acute angles determining the formation of four fingers with an L-shaped or right-angled section. - A thin disc-
shaped seal 15 of aluminum or similar material, easily piercable when appropriate, hermetically closes the housing as a result of aperipheral rim 16. Such housing incorporates in the outer face of its base adisc 17 of a porous material acting as a filter. - The
disc 17 is of a flexible, porous and air-permeable and also moisture-absorbing material. - After the
housing 10 and its associated elements are placed, thelower lid 8 is arranged, which is fixed by the aforementioneddouble crimp 24, which gathers together in a completely leak-tight manner thelid 8, thefilter 17, theflange 9′ of thecontainer 9 and the lower flange 2 of thebody 1, while at the same time it holds thehousing 10 such that it is completely locked. - The assembly of the self-heatable container which is described from its components can be stated as follows:
- A certain amount of water is placed in the
housing 10, and it is hermetically closed by means of theseal 15, the inner face of which is supported exactly on thecentral projection 13 and its fingers with a right-angled section. Thefilter disc 17 is likewise incorporated to it. - Separately, a certain amount of a
product 20 such as calcium oxide which, upon contact with water, will give rise to an exothermic reaction, is placed in thecontainer 9. Thecontainer 9 with its content introduced in the mouth of the cylindricallower part 6 of thebody 1, according toFIG. 3 . - Then the
housing 10 and its annexes are introduced in the joint mouth of thecomponents FIG. 3 , after which thelid 8 is fixed, followed by the already mentioneddouble crimp 24 which assures the hermetic closing of this end part of the container, i.e., the associated edges of thelid 8, thefilter 17, thehousing 10 and thecontainer 9. The latter is absolutely locked with respect to thebody 1. - Inverting the position of the
body 1, passing to the position ofFIG. 5 , the desired amount of the food product (beverage or the like), the consumption of which will optionally take place after heating, is poured through the upper mouth of such body. The product bathes the upper and side part of thecontainer 9 and likewise occupies thelower part 19 located between thebody 1 and theactual container 9, according to the mentionedFIG. 5 . Finally theupper lid 3, which is fixed by a conventional peripheral crimp, is placed. - In most cases and according to the type of product contained, a sterilization of the finished container (with its heating module incorporated) then takes place in an autoclave at a temperature and pressure suitable for the characteristics of the product. The sterilization is possible given the simplified configuration and the metallic nature of the new container, and the latter is ready for its final conditioning, which occurs with the placement of a preferably tubular and laminar label 18.
- It can likewise be emphasized that the
lower lid 8, fixed by thesafety crimp 24, closes and holds all the components of the heating module associated with thecontainer 9. - Use. The consumption of the beverage contained in the
body 1 takes place, with regard to its prior heating, by partially extracting thelower lid 8, retained by thecrimp 24, which leaves thefilter 17 and, behind it, the dome or (flexible)central part 12 of the housing exposed. This central part is pressed, whereby theprojection 13 moves forward in an axial direction and, like a striker, causes the tearing of theseal 15 and the passage of the water contained in the housing into thecontainer 9. The water contacts thecalcium oxide 20 contained in the mentioned container, initiating the exothermic chemical reaction which gives rise to a considerable increase of the temperature of theactual container 9. - The container with its content is shaken for 10 seconds to facilitate the mixture of the reagents and is again inverted, leaving it face up (
FIG. 5 ). In less than 30 seconds the heating is noted due to the exothermic chemical reaction, which gives rise to a considerable increase of the temperature of the surface of thecontainer 9 and, as a result, of the product. - Finally, the user, in less than 3 minutes, can open the mouth of the container by separating the
upper lid 3 and have access to the heated beverage. - The wall of the body metallic 1 is obviously also heated with the previous operation, normally at a high temperature which can be, for example, of the order of 65-70° C., since the container is designed so that the temperature of the content rises from 38 to 40° C. with respect to the environment. To that end and to prevent the inconvenience and risk of burning for the user when holding the
body 1 of the container, the label 18 is made of a heat-insulating material, such as polystyrene. - As a result of the chemical reaction occurring inside the
container 9, a condensation of the moisture contained in the hot air can occur upon contacting a cold surface (for example, the surface of a table on which the container is placed). - In the event that the container is not inverted after the activation of the reaction, the content will not be suitably heated and some amount of vapor may appear, which will be partly absorbed by the
filter disc 17. - Two important details must be emphasized in the design of the
housing 10. In the first place, theopenings 21 existing in thecrown 22 determine air passages between the outside and the inside of thecontainer 9 and assure that the reaction always occurs at atmospheric pressure, whereas theribs 23 reduce to a minimum the amount of calcium hydroxide in powder form, resulting from the reaction, which could be deposited on thefilter disc 17. - It is recommendable to use a protective element for the user's lips, by means of the use of an incorporable and separable ring made of an insulating material, which does not form part of the object of the present patent.
