Self-heatable container

Abstract

The present invention related to a container for food and other products, where said container comprises: An upper compartment or part and a lower threaded lid; in the upper compartment is placed the contents of the product that can be food, and others. The lower threaded lid is interchangeable and allows the reuse of the upper compartment, and the arrangement of the upper compartment in an extended manner and under the upper compartment allows easy, quick and practical interchangeability of the lower threaded lid, without needing to flip the upper compartment in order to place or remove it. Likewise, the upper threaded lid is protected by a security seal at the junction between the upper threaded contour and said upper threaded lid. The package or container has at least one flexible and adaptable handle. Between the upper compartment and the inner container there is a free space through which the heat flows and surrounds the outside of the entire inner container, which holds the content of the product. The lower threaded lid has an integral mechanism of compounds that houses the chemical compounds that allow food to be heated and remain hot; said chemical compounds are calcium oxide or calcium chloride and water, separated by a breakable sheet and/or a breakable container. The calcium oxide or calcium chloride and the breakable water container are placed separately, as well as at least one striking mechanism for breaking the water container, allowing the elements to combine, producing an exothermic reaction. The lower threaded lid is joined to the upper compartment through a threaded connection and optionally an adhesive tape that makes it possible to maintain the temperature and avoid possible leaks of the content that is inside the container. There are three optional mechanisms for activating the self-heating device.

PREFERRED EMBODIMENT OF THE INVENTION

[0108] As mentioned above, the present invention is constituted by a package comprising an upper compartment (5) and a lower compartment (6); the height of the container is preferably 10-15 cm of height; the material is aluminum, stainless steel, tinplate, among others; thin thickness. The measures and designs of the container are made according to the type of product to be heated and also according to the quantity of the product.

[0109] The upper compartment (5) measures 10-12 cm, here is held the contents of the product, which can be chocolate, coffee, and other products and food. Once the content of the product is filled, the upper mouth of the contour of the container (4) is sealed with a thin aluminum sheet (9), after which the threaded upper lid (2) is placed, this lid is made of polyethylene material or others which fits into the upper threaded contour (4), such upper threaded contour (4) is made of polyethylene covered with polystyrene or polyurethane, etc. This is so that the heat felt in the upper contour (4) is minimal and can be taken to the mouth with no problems.

[0110] Likewise, the upper threaded lid (2) has a fitting contour of the cover (4.a), where the cover (1) fits perfectly, this cover (1) holds certain special foods such as baby formula, ingredients of the soup, and so on, which works as follows: the baby formula (milk powder) is filled in the cover (1) and immediately protected by sealing it with an aluminum foil (9), this is so that milk and other special foods do not lose their vitamins, proteins, etc. (its nutritional value). The cover material (1) is made of polyethylene or others and measures 4 to 5 cm. After all this, the upper security seal (20.a) is placed, which is made of adhesive material, polyethylene or paper or others.

[0111] The entire body of the container (7) has a measurement of 10 to 15 cm. In between the compartments (5; 6), there is a free space (8) of 1 to 2 mm, this measurement is according to the size and design of the container (7). Through this free space (8) the heat flows and surrounds the contour of the container, causing the entire content of the product to be heated evenly. The inside of the container is lined up with a thin sheet (10), made of polystyrene, aluminum, polyurethane or thin cardboard, etc. which prevents any type of leakage of the contents.

[0112] The outer part of the container is covered by an insulating sheet (12), made of extended polystyrene, polyurethane, and others, for insulating and blocking heat, so that when the container is touched only minimal heat is felt and is suitable for the user's touch. Next to it, is placed the second outer sheet (11) or the label, made of polyethylene, thin cardboard, or others.

[0113] Likewise, the container has two fasteners on both sides which are two adaptable and flexible handles (13) of polyethylene, or others, etc. These handles (13) are initially straight, and when pressing the handle fitting (13) they turn oval and this is how the handles are formed.

[0114] As for the lower threaded lid (6), activation mechanisms (30-40-50) are installed inside such lower threaded lid (3), and also there it is located the mechanism of the integral chemical compound accessory (14), which is of (3-3 cm.) of height, made of aluminum, etc. and it has three levels (14.1; 14.2; 14.3), each level is lined up by an aluminum sheet (16), the floor of each level has holes, in the second level (14.2) is the water accessory (14.a), covered by an aluminum foil (16.a) with chopped points, on the sides and at the bottom of the water accessory (14.a). The sheet (16.a) is there to protect the water container (15), in such a way that when it is triggered the striker breaks the chopped aluminum sheet (16.a) and subsequently breaks the water container (15).

[0115] Inside the water accessory (14.a), is located the water container (15), which is a container or a wrapper made of polyethylene-coated latex, aluminum-coated latex or aluminum-coated polyethylene, among others.

[0116] Also, there are chemical elements of compound 1 (calcium oxide (17) and water (19)), compound 2 made up of (calcium chloride (18) and water (19)). The amount of both substances depends on the amount of the contents of the product to be heated, for example, for a 250 ml drink the compound is 35 g of calcium oxide (17) and 17 ml of water (19). Both elements, calcium oxide (17) and water (19) are separated and at the moment of activation they mix and produce the exothermic reaction that gives off heat in the form of steam and begins to heat the contents of the product in a period of 1-5 minutes, this allows food to stay warm longer.

[0117] The lower threaded lid (3) works as the self-heating device and is a removable lid for the reusable system and a non-removable lid for the single-use system. Once all the elements (17; 18; 19) of the integral compound mechanism (14), and the strikers with their respective activation mechanisms are installed, the lid is screwed and sealed with the lower part of the upper compartment, being amalgamated with the container. Next, the lower security seal (20.b) is placed, which should preferably be thick and of cardboard covered with polyethylene, among others. Additionally, the protective sheet (21) should be made of polystyrene covered with foil aluminum, or the like.

[0118] There are three activation mechanisms of the self-heating device.

[0119] The 3 activation mechanisms are applicable for both the reusable self-heating container and for the single-use, non-reusable container.

[0120] In the case of the self-heating single-use container, the non-removable lower threaded lid (3) is attached and hermetically sealed to the container body (7) and therefore the lower threaded lid (3) cannot be removed, taken out or detached because said lower lid (3) is solidly attached to the body of the container (7). This is done for safety purposes and to avoid leakages, etc. Likewise, the activation mechanisms (30-40-50) and all the elements that produce the exothermic reaction are already installed inside the lower threaded lid (3): calcium oxide (17), calcium chloride (18), and water (19) which are housed inside the integral accessory (14) which itself is also located inside the lower threaded lid (3).

[0121] For the reusable self-heating container system, there is an easily removable lower threaded lid (3). It is only needed to place and rotate the lower threaded lid (3), which is easy to put in and take out. Inside the lower threaded lid (3) the activation mechanisms (30-40-50) are already installed, and all the chemical elements that produce the exothermic reaction: calcium oxide (17), calcium chloride (18), and water (19), are housed inside the integral accessory (14) which itself is located inside the lower threaded lid (3). When taking the last turn on such lower threaded lid, it is closed completely and compacts the contents further, sealing fully the container and preventing all leaks. All this is done for safety, since in the lower part is where all the chemical compounds and formula of the self-heating device are concentrated.

[0122] The first is a rotating activation mechanism (30). It works as follows: first the security seal is removed from the lower part (20.b), then put a hand on the lower threaded lid (3) and rotate and the device is activated. On the lower part of the container bottom the lower threaded lid (3) is placed. In the center of the lower threaded lid (3), there is a striker accessory with two arms (30.a), which has on both sides pointed striking accessories making a total of three pointed accessories on top of the same base. Also, on the base of the inner receptacle is placed a one-arm striking accessory (30.b). The lower threaded lid (3), when turning, rises and causes the water container (15) to break, and the device is activated, starting to heat the product.

[0123] The second activation mechanism is with activation button 1 (50). It works as follows: first the lower security seal (20.b) is removed, then the two striking accessories with side buttons (50.a) are pressed, each button internally has a striking accessory (50.a), which lo when the buttons are pressed on, cause the water container (15) to break and the self-heating device to activate, starting to heat the product.

[0124] There is also the Activation Mechanism with activation button 2 (50). It works as follows: first, the lower security seal (20.b) is removed, and at the same time the two buttons (50.d) are pressed upwards; such buttons (50.d) have a striker accessory with linked buttons (50.c), which is the intersection and by which the buttons (50.d) are coupled and held at the same base. These buttons (50.d) work together either when pressed up or down. Pressing both buttons (50.d) upwards causes the striker accessory (50.c) to rise and cause the water container (15) to rupture and the self-heating device to activate, starting to heat the product.

[0125] The third mechanism is with fitting accessory 1 (40); which works as follows: the lower security seal (20.b) is removed, then the striker accessory (40.a) is inserted in the lower side of the container (7), being perfectly fitted in the fitting accessory (40.b). The inserted striker accessory (40.a), has an irreversible threaded design not to be removed nor taken out again. This inserted striker accessory (40.a) has an elongated, pointed shape and is made of polyethylene or others, the accessory (40.a) is glued on the same lower side of the container (7). When introducing the striker accessory (40.a), the rupture of the water container (15) is caused and the device is activated, starting to heat the product.

[0126] There is also the Mechanism with fitting accessory 2 (40); which works as follows: the lower security seal (20.b) is removed, and the rotating striker accessory (40.c) is rotated and the accessory fits perfectly into the fitting accessory (40.b) of the container (7). This rotating striker accessory (40.c) has a non-removable threaded shape and is irreversible to be removed or to be taken out again, it is elongated, pointed, flexible, and is made of polyethylene or others.

[0127] By fitting the rotating striker accessory (40.c), the rupture of the water container (15) is produced, and the device is activated starting to heat the product.

[0128] Moreover, the three activation mechanisms are applicable to both single-use self-heating container systems and reusable self-heating container systems.

[0129] Therefore, the activation mechanisms and the other components of the lower threaded lid can be used in the two self-heating container systems: a single-use system and a reusable system.

[0130] The Reusable Self-Heating Container System consists of a container with two threaded lids, (one upper and one lower), the product contents are placed in the upper compartment and the self-heating device is placed in the lower threaded lid, which is a lower threaded lid that houses inside all the chemical elements that heat the product. To reuse the container it only needs to be washed and to reheat any product, only place a new elf-heating device on the lower threaded lid (the device is the same as the lower threaded lid).

[0131] The Self-Heating Single-Use Container System; consists of a container with one upper threaded lid (removable) and a lower lid (non-removable), the lower lid is attached and hermetically sealed to the body of the container, for safety purposes and to avoid leakages, etc. since these containers are for single use and for ready-made foods among others. The content of the product is placed in the upper compartment and the self-heating device is placed in the lower threaded lid, which is a non-removable lower threaded lid attached and sealed to the body of the container or to the upper compartment. The lower lid houses inside it all the chemical elements that heat the product. In order to reuse the container, only needs to be washed and to reheat any product, only place in the lower compartment a new self-heating device that is the same as the lower threaded lid.

[0132] Once the nature of the invention has been sufficiently described, as well as the preferred embodiment, it is stated for the appropriate purposes that the materials, shape, size and arrangement of the described elements may be modified, provided that this does not entail an alteration of the essential features of the invention that are claimed below.
