Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to a container with a heating function that utilizes heat generated by a self-combustion reaction of a combination of a combustible agent and an oxidizing agent.

(Prior Art) It has been known for a long time to use a combustion reaction that combines a combustible agent and an oxidizing agent as a heating method for food and drinks. Publication No. 24119 describes a device that heats a liquid by inserting a heating cylinder containing a heating agent using a combustion reaction into a metal cylinder with a bottom and igniting a fuse connected to the heating agent with a pine or the like. is introduced.

Furthermore, Japanese Patent Publication No. 27-582 discloses a heating device in which a metal cylinder with a bottom is filled with a heating agent that utilizes a combustion reaction, and a device for filtering gas and smoke is attached to the top end of the heating cylinder. There is.

(Problems to be solved by the invention) However, in the heating device as disclosed in Utility Model Publication No. 58-24119, flame blows out from the ignition part.
Also, because the heating device was not fixed to the container, there was a risk of burns during handling.

In addition, in the heating device as disclosed in Japanese Patent Publication No. 27-582,
Since a filtration device and the like are attached, it was difficult to fix it to the paper or plastic side wall.

(Means for Solving the Problems) The present inventors have studied the above-mentioned problems and have devised a container that is easy to handle and can be heated efficiently.

That is, in the present invention, a heating container 3 containing a self-combustible heating agent 4 is fixed to the side wall of the container via a support 2 having a built-in ignition device 5 and a filter 6 inside the container 1 whose upper end is open. However, it is a container with a heating function in which a space is provided between the bottom wall of the container 1 and the heating container 3 so that at least liquid can enter.

The present invention will be described below with reference to the drawings.

The container body 1 of the present invention with an open top end is not limited to the cup-shaped one shown in FIGS. 1 and 2, but may also be a container with a removable lid, and may be made of paper, polyethylene, or polyethylene terephthalate. Any material that is commonly used as containers for food and beverages may be used, such as metals such as aluminum and aluminum.

The support 2 for connecting the container body 1 and the heating container 3 of the present invention may be made of plastic, but is preferably made of a metal tube such as aluminum or copper.
Note that if it is necessary to bond the support 2 and the container body 1 or the heating container 3, they are bonded using hot melt or adhesive.

Inside the support 2, there is a filter 6 made of inorganic sponge or glass wool for filtering gas particles emitted when the self-combustible heating agent 4 burns, and an ignition device 5 for igniting the self-combustible heating agent 4.
is built-in. The ignition device 5 may be of any structure as long as it is ignited by a fuse or a filament type electric heater. Further, after the ignition device 5 is installed, it is preferable to cover the surrounding area with a seal or the like in order to prevent the heating agent 4 and the ignition device 5 from absorbing moisture.

The support 2, the container body 1, and the heating container 3 are bonded to each other by hot melt adhesive or welding to prevent liquid from leaking.

The self-combusting heating agent 4 used in the present invention is composed of a mixture of a combustible agent and an oxidizing agent, generates a small amount of gas during combustion, and has the amount of heat necessary to heat food and drink. Metal powders such as silicon powder, silicon iron powder, and copper powder are used as the fuel, and metal oxides such as trilead tetraoxide, iron oxide, and barium peroxide are used as the oxidizing agent. Further, the heating container 3 that houses the self-combustible heating agent 4 is preferably a metal container made of aluminum, copper, iron, etc. and formed into a plate shape for efficient heat conduction.

Since the combustion temperature of the self-combustible heating agent 4 used in the present invention is usually high and reacts, the heating container 4
It is necessary that at least the liquid comes into contact with the surface of the support 2 and the surface of the support 2. That is, there needs to be a gap between the bottom surface of the heating container 3 and the bottom wall of the container body 1 that allows at least a liquid such as water to enter.

(Effects) The heating function container of the present invention is safe to handle because the heating container is fixed to the side wall of the container, and has excellent thermal efficiency, so it can heat alcohol, coffee, tea, milk, soup, etc. It can be said that this device is extremely suitable for

[Brief explanation of the drawing]
