Hereinafter, embodiments of the present invention will be described, but the present invention is not limited to these embodiments.

<Heating element of the present invention (1)>
FIG. 1 shows an embodiment of the heating element 1 of the present invention. The heating element 1 of the present invention has a structure in which the "heating agent (2)" is enclosed in the "bag material (3)".

-Exothermic agent 2-
In the present invention, the exothermic agent 2 is in various dosage forms such as powder, paste, and fixed shape. In the present embodiment, for the exothermic agent 2, a powdery exothermic composition utilizing the exothermic heat generated by the oxidation reaction of iron powder was used.

-Bag material 3-
In the present invention, the bag material 3 includes a "main chamber (31)" and a "sub chamber (32)" independent of the main chamber 31. The main chamber 31 is a space for encapsulating the exothermic agent 2, and the sub chamber 32 is a space for encapsulating the capsule 4 described later. In the present embodiment, two breathable sheets 30 (30A, 30B) having a two-layer structure in which a polyester non-woven fabric is laminated on one surface of a polyethylene breathable film are laminated to form the main chamber 31 and the sub chamber 32. The bag material 3 was obtained by applying a heat seal to the area other than the area to be covered. The state in which the sub chamber 32 is "independent" from the main chamber 31 means that the space in the main chamber 31 and the space in the sub chamber 32 are not continuous.

-Capsule 4-
The capsule 4 means a dosage form in which a drug 41 having some function is encapsulated by a capsule 40. In the present embodiment, a liquid air freshener (terpene-based air freshener) is used as the drug 41, and the seamless capsule in which the drug 41 is encapsulated in a spherical (diameter 3 mm) capsule (gelatin-based seamless capsule) 40 is used as the capsule. It was used as agent 4. Further, the capsule strength 4 is adjusted so that its capsule strength is 10N. In the present invention, the "seamless capsule" means a seamless capsule manufactured by utilizing the property that a liquid becomes spherical due to its interfacial tension. Further, in the present invention, the "capsule strength" refers to the load (compression) at the time when the capsule 4 fixed to the pedestal so as not to roll is subjected to a vertically downward load and the capsule 4 is crushed. Strength). In this embodiment, a tensile compression tester (model: SV-55CA) manufactured by Imada Seisakusho Co., Ltd. was used as a measuring instrument for measuring the capsule strength.

The heating element 1 of the present invention having the above configuration is sealed in a non-breathable outer bag and is used for distribution and storage in a state of being isolated from the outside air. Then, in the heating element 1 of the present invention, when the outer bag is opened, the heating agent 2 and the oxygen that has passed through the bag material 3 come into contact with each other in the main chamber 31, and start generating heat.

On the other hand, the capsule 4 existing in the sub-chamber 32 is not affected by this opening operation. In the present embodiment, the function (fragrance in this case) of the drug 41 encapsulated in the capsule 4 is that the user applies pressure to the capsule 4 through the sub-chamber 32 as shown in FIG. In addition, it is expressed by crushing the capsule 40.

That is, the heating element 1 of the present invention can arbitrarily select the timing of generation of the function of the drug 41 encapsulated in the capsule 4 at a timing different from the timing of generation of heat by the exothermic agent 2. .. Of course, in the heating element 1 of the present invention, the function of the drug 41 may be generated at the same time as the generation of heat, or the function of the drug 41 when the oxidation reaction of the heating agent is completed and the generation of heat is stopped. May be generated.

By the way, in the present embodiment, a seamless capsule is used for the capsule 4, but in the present invention, a soft capsule or a hard capsule may be used for the capsule 4. Further, the material of the capsule 40 forming the outer shell of the capsule 4 is not particularly limited, and in addition to gelatin, for example, a polymer material such as starch, agar or carrageenan can be arbitrarily selected.

Further, in the present embodiment, the capsule strength of the capsule 4 is adjusted to 10N, but in the present invention, the capsule strength of the capsule 4 is not particularly limited. The capsule strength of the capsule 4 may be adjusted so that it can be easily crushed by pressing with a finger, and is preferably 5 to 50 N so that a comfortable feel can be obtained when crushed.

In the present embodiment, the user applies pressure to the capsule 4 through the sub-chamber 32 to crush the capsule 40 to express the function of the drug 41 encapsulated in the capsule 4. However, the opening of the capsule 4 (opening of the drug 41) is not limited to the case of pressure. For example, the capsule 40 forming the outer shell of the capsule 4 is constructed of a thermoplastic material such as paraffin wax, and the capsule 40 is formed after a certain period of time has passed from the generation of heat generated by the heating agent 2 even if no pressure is applied. It may be a mechanism that melts away.

Further, in the present embodiment, the capsule 4 has a spherical shape having a diameter of 3 mm, but in the present invention, the shape and dimensions of the capsule 4 are not particularly limited. The size of the capsule 4 is preferably a triaxial average diameter of 0.5 to 10 mm.

In addition, in the present embodiment, a liquid air freshener was used as the drug 41 encapsulated in the capsule 4, but in the present invention, the type and dosage form of the drug 41 encapsulated in the capsule 4. There is no particular limitation. As the agent 41, various functional compositions such as a cooling agent such as menthol and peppermint oil and a deodorant such as silica gel and activated carbon can be arbitrarily selected in addition to the air freshener. As the dosage form, various dosage forms such as liquid, powder, and granular can be appropriately selected.

In the present embodiment, the bag material 3 is provided with two sub-chambers 32, and one capsule agent 4 is sealed in each of the sub-chambers 32. However, in the present invention, the number of the sub-chambers 32 and the number of the sub-chambers 32 are increased. The number of capsules 4 to be encapsulated in the sub-chamber 32 is not particularly limited. For example, as shown in FIG. 3, a plurality of capsules 4 may be encapsulated in the sub-chamber 32. In this case, it is not necessary to use the same type of the drug 41 to be encapsulated in each capsule 4, and various capsules 4 in which the drugs 41 having different functions are encapsulated may be enclosed in the sub-chamber 32.

Further, in the present embodiment, as the bag material 3, a package having a four-sided seal structure having a rectangular overall shape is used, but in the present invention, the shape, structure, and material of the bag material 3 are not particularly limited. .. The bag material 3 may have a shape that can be used as an eye mask as shown in FIG. 4, for example. The eye mask-shaped heating element 1 of the present invention shown in FIG. 4 is formed by laminating another breathable sheet 30B via an adhesive 5 applied to one side surface (inner surface) of one breathable sheet 30A. By interposing the exothermic agent 2 and the capsule agent 4 between the two breathable sheets (30A, 30B) at the time of laminating, the main chamber 31 in which the exothermic agent 2 is sealed and the capsule agent 4 are formed. It forms an enclosed sub-chamber 32.

It should be noted that the present invention can be carried out in various other forms without departing from its spirit or main features. Therefore, the above embodiments are merely exemplary in all respects and should not be construed in a limited way. The scope of the present invention is shown by the scope of claims and is not bound by the text of the specification. Furthermore, all modifications and modifications that fall within the equivalent scope of the claims are within the scope of the present invention.

The heating element of the present invention can be used as a heating tool that can arbitrarily select the timing of generation of a function different from the heating such as aroma.
