SELF-HEATING CONTAINER
The present invention relates to a heating container. There are types of food which should be eaten after being warmed up at home or in a restaurant. Hot sops or hot stews can be eaten after being heated on a portable gas range. However, it is impossible or very inconvenient to heat pan-fried foods, boiled beef, fried foods, rice cakes and the like on a gas range. The heating container of the present invention has a self-heating function and is very useful because the heating container allows food to be kept warm until the end of the meal when various foods are placed on the heated heating container, whereby enabling the distinct tastes of the foods not to be lost until the end of the meal.
The present invention relates to a self-heating container which is different as compared to a conventional heating container which is designed to be directly heated and is currently, widely used. Since the conventional heating container does not have a self-heating function, the increased heat is gradually cooled as time passes. In the event that the heat is increased to a high level in an attempt to keep the increased heat lasting long, the heat becomes too hot at the very beginning of heating, and then the heat is gradually cooled, so there is a big heat difference, which might make foods have no taste, and it is inconvenient to use.
BACKGROUND ARTMost of housewives does a lot of work at home making foods, and the tastes of foods at a restaurant might be a key factor which determines the success of the business, so a lot of efforts is contributed to making the foods have taste. When a certain food which needs to keep warm until the end of meal is fast cooled on a table, a restaurant guest might not enjoy eating the well cooked foods, which leads to ruining a restaurant business. Therefore, it is important to make the foods have taste as well as it is important to facilitate the heat of the foods to last until the end of meal. In terms of the forgoing, a self-heating container according to the present invention can be very useful since it is possible to keep the initial heat of the foods until the end of meal.
DISCLOSURE OF INVENTIONAccordingly, it is an object of the present invention to provide a self-heating container which has a self-heating function, an easier heating control, a function generating a certain level temperate appropriate to a corresponding food, and a function making the temperature last long, with the container being repeatedly used, along with a reliable safety and low cost feature.
To achieve the above objects, there is provided a self-heating container characterized in that a self-heating function is implemented using a solution such as sodium acetate, sodium thiosulfate, etc. or an aqueous solution generally used to manufacture a hand-held stove, and a snap button type impact device capable of impacting a heating trigger member is used to make a module-type operation kit which results in an easier operation, thus engaging the module at the container. When the amount of the material is a lot, a longer heating time is needed depending on the thickness of the container, and when the amount of the same is small, the heating time relatively shortens. The high and low of the temperature can be adjusted by adjusting the amount of a solution such as sodium acetate, sodium thiosulfate, etc. or the amount of an aqueous solution and the ratio of water, and the container used is inputted into boiling water or is processed to have required conditions for the use at the microwave range. All the elements of the self-heating container are cheap, and an efficient self-heating container can be manufactured.
ADVANTAGEOUS EFFECTSThe heating container according to the present invention has a self-to heating function and can be half permanently, repeatedly used, and a heating control is easy, and the construction of the heating container looks simple, and the industrial applicability is excellent.
The present invention will become better understood with reference to the accompanying drawings which are given only by way of illustration and thus are not limitative of the present invention, wherein;
The preferred embodiments of the present invention will be described with reference to the accompanying drawings.
Claims
1. A self-heating container, comprising:
- a double container inner space part 12 formed of a double container upper layer 10 and a double container lower layer 11, with a solution such as sodium acetate, sodium thiosulfate, etc. or an aqueous solution being filled in the double container inner space part 12, and
- an impact module 35 with an impact elastic member means 21.
2. A self-heating container according to claim 1, wherein the materials of said double container upper layer 10 and said double container lower layer 11 are stainless steel.
3. A self-heating container according to claim 1, wherein the materials of said double container upper layer 10 and said double container lower layer 11 are synthetic resin.
4. A self-heating container, comprising:
- a double container inner space part 12 of which either a double container upper layer 10 or a double container lower layer 11 is made from an inoxidable metallic material, with the other layer being made from a synthetic resin material, with a solution such as sodium acetate, sodium thiosulfate, etc. or an aqueous solution being filled in the double container inner space part 12, and
- an impact module 35 with an impact elastic member means 21.
5. A self-heating container, comprising:
- a double container inner space part 12 formed of a double container upper layer 10 and a double container lower layer 11, with a solution such as sodium acetate, sodium thiosulfate, etc. or an aqueous solution being filled in the double container inner space part 12, wherein a reaction of a solution such as sodium acetate, sodium thiosulfate, etc. or an aqueous solution is trigged as a certain impact is externally inputted using an ultrasonic oscillation means.
6. A self-heating container, comprising:
- an impact module 30 configured in such a way that a circular circumferential portion is protruded to form a small container shape and having an impact module inner space 17 and an assembly groove 16 formed by forming a protrusion at its lower and upper side, respectively, in order for the assembly groove 16 to be formed at an upper side of an outer circumferential portion, with the assembly groove 16 being formed in order for the impact elastic member means 21 to help form itself in a polygonal shape, with a recovery spring 20 being provided at a lower side of the impact elastic member means 21, thus helping recover the impact elastic member means 21, with a protrusion part 22 being formed in the vicinity of the double container upper layer 10 at the upper side of the impact elastic member means 21, and in the above construction as the center portion where the protrusion part 22 of the double container upper layer 10 is pressed, the protrusion part 22 strongly presses the impact elastic member means 21, and said impact elastic member mean 21 with its outer circumferential side being caught by means of the escape prevention shoulder 14 is configured with its upper side being concave, and its lower side being convex, so the impact elastic member means 21 stores elastic force, and when a user releases his hand from a pressing state of the double container upper layer 10, the protrusion part 22 no longer presses the impact elastic member means 21, and the impact elastic member means 21 can recover for itself, but the recovery can be easily performed by means of an elastic force of the compressed impact elastic member means 21, and here since the impact elastic member means 21 is caught by means of the escape prevention shoulder 15, it does not disengage from the assembly groove 16, and a solution such as sodium acetate, sodium thiosulfate, etc. and an aqueous solution in the double container inner space part reacts, thus generating heat.
