Description

[Detailed description of the invention] (Industrial field of application) This invention relates to a food container that can be heated and eaten in a timely manner.

(Prior Art) Lunch containers that also serve as heat-retaining jars are known, but they are not effective when left outdoors in the cold or for a long time.
It is also large and inconvenient to carry.

(Problems to be solved by the invention) In view of the above points, the present invention aims to provide on the market a food container that is convenient to carry and can be heated and used as needed. ,
It is especially suitable as a lunch box container.

(Means for solving the problem) The present invention forms a double bottom of the container and seals a certain amount of quicklime and water in a separate state inside.
The two can be safely and easily mixed and heated as necessary.

Specific examples will be explained below based on the drawings.

1 is a container body made of heat-resistant polystyrene foam, 2 is an aluminum foil that is stored in a similar shape to the bottom of the container, and there is a certain gap S (approximately 1 cm to 1 cm) between the two.
A chamber 3 having a diameter of about 2 cm) is formed. 4 is a quicklime bag to be filled into the chamber, and 5 is a water bag, each of which is made of synthetic resin film or other water-resistant bag with an appropriate amount of material, that is, as an example, the former is 150g and the latter is 125g. Both are integrally connected via a string 6 in a left-right distributed manner at the center, with the ends of the string protruding outside the side wall of the container body 1.

In the illustrated example, a water bag 5 is integrally connected to the quicklime bag 4 via a string 6, and when the string is pulled during use, which will be described later, both bags are torn and the quicklime and water are mixed. This will cause fever.

The string 6 is designed to be able to be stretched for a long time while effectively breaking the joint between both bags. The other end of the cord is suspended outward through the section, and a gripping member 8 with a loop is provided at the end of the cord to facilitate pulling. This has the effect of preventing the end of the string from accidentally entering the inside of the container.

Note that a seal piece 9 is pasted to the location of the through hole 7.

Next, the interior of the aluminum foil 2 is appropriately partitioned, taking the case of a lunch box container as an example, and rice 10, various side dishes 11, etc. are packed therein. At this time, the aluminum foil 2 is preferable because it has good thermal conductivity and can effectively heat the internal food, and allows the rice and side dishes to be heated at different temperature conditions as necessary. For this purpose, the thickness of the aluminum foil can be made different or a different sheet material can be provided inside.

In the present invention, the aluminum foil can be replaced with other materials having the same effect, but in either case, the upper edge e and the upper edge f of the container body are sealed in a tightly mating state. Note that 12 is a heat-resistant Styrofoam lid.

(Function) The container of the present invention has the above-mentioned structure, and when it is used to warm the food inside, the grip member 8 protruding from the outer wall is held in the hand and pulled. As a result, the internal string 6 breaks the bag of water and quicklime, and the two are mixed together, causing the quicklime to generate heat and heat the bottom of the aluminum foil. The steam generated at this time is discharged to the outside through the through hole 7, which is formed by a relatively large window 7 through which the string 6 is inserted.

The heating temperature is determined by the relationship between the amount of quicklime and water, and if the amount of quicklime is constant, it will vary depending on the amount of water. That is, when the amount of water decreases, it will be heated at a high temperature, and when it increases, it will be heated at a low temperature.

(Effect of the invention) According to the inventor's experiments, the overall temperature is approximately 50℃ to 80℃.
It is sufficient if the temperature can be heated to 100%, but it can be heated further. The heating time is approximately 10 to 15 minutes, and by using the container of the present invention, even in the coldest of winters, it is possible to easily make a warm lunch box and eat it deliciously outdoors.

In the above embodiment, the use of heat-resistant styrene foam for the container body is advantageous in that it is lightweight and convenient to carry.

In addition, in the present invention, since the bag containing a certain amount of quicklime and water is formed into a flat bag arranged in a left-right distribution at the center, the overall volume can be made compact and not bulky. Moreover, since the window for blowing out the steam is also provided as an outlet for the tow cord, it is convenient to use and also has excellent safety.

Claims (1)

[Scope of Claim for Utility Model Registration] (1) The lower bottom of the container body is formed in double layers, and bags for enclosing a certain amount of quicklime and water are placed in the center part in a divided manner on the left and right sides, A string is provided at the center of the bag so that the left and right bags can be torn when pulled.The string is attached to a window drilled in the outer wall of the container body via a seal piece, and the end of the string is attached to the outside of the wall. 1. A food container, characterized in that when the end of the string is pulled, the bag ruptures and water and quicklime mix to generate heat, and the window serves as an outlet for the generated steam. (2) The food container according to claim 1, wherein the container body is made of heat-resistant styrofoam.
