(First embodiment of the present invention)
FIG. 1 is an external perspective view of a heating pack 1 showing a first embodiment of the present invention. FIG. 2 is a cross-sectional view taken along the line AA of FIG.

  The heating pack 1 heats an object to be heated by utilizing the heat generated by the heat generating agent 42 reacting with the water 32. The heating pack 1 includes a container 2, a water pack 3 accommodated in the container 2, a heating agent pack 4 accommodated in the container 2 on the water pack 3, and heat generated in the container 2. A bag breaking member 5 disposed on the agent pack 4 and a sealing material 6 for sealing the container 2 are provided.

  The container 2 has an opening 2b on the upper surface 2a. The container 2 is formed using a heat resistant material. As the heat resistant material, a resin having a melting point higher than the temperature at which the heat generating agent 42 reacts with the water 32 to generate heat is used. Examples of other heat resistant materials include metals and ceramics.

  The water pack 3 is a bag 31 in which water 32 is sealed. The bag 31 is formed by sealing water sealed in a bag 31b formed of a material that is soft and can be broken by the bag breaking member 5 with a circular disk 31a. The disc 31 a is fixed to the bottom surface 2 c in the container 2 with an adhesive member 7. In addition to the water 32, an aqueous solution may be used. The amount of water in the aqueous solution is such that the exothermic agent reacts sufficiently.

  The heat generating agent pack 4 is a water permeable bag 41 in which a heat generating agent 42 is enclosed. The water-permeable bag 41 is formed in an annular shape, for example, on an annular disk 41a formed of a hard resin so as to cover a nonwoven fabric 41b formed in a substantially semicircular cross section. Thereby, the heat generating agent pack 4 is disposed in contact with the outer surface 3 a on the water pack 3. The exothermic agent 42 is one in which the water 32 in the water pack 3 passes through the water permeable bag 41 and reacts exothermically. As a specific exothermic agent 42, calcium oxide is used. A known exothermic agent other than calcium oxide may be used.

  The bag breaking member 5 is for breaking through the water pack 3. The bag breaking member 5 is disposed on the heat generating agent pack 4 stacked on the water pack 3. In addition, the bag breaking member 5 is formed of a heat-resistant material like the container 2. Further, as shown in FIGS. 2 and 4, the bag breaking member 5 includes a flat plate portion 51, a blade portion 52 provided at a central portion of the lower surface 51 a of the flat plate portion 51, and a blade on the lower surface 51 a of the flat plate portion 51. And a plurality of pressing protrusions 53 provided around the portion 52. Specifically, the pressing protrusions 53 are provided on the front, rear, left and right sides of the blade portion 52.

  The flat plate portion 51 is formed in a disc shape as shown in FIG. A plurality of semicircular cutouts 511 are formed on the outer peripheral portion of the flat plate portion 51. In addition, a circular hole 512 is provided between the adjacent pressing protrusions 53 on the lower surface 51 a of the flat plate portion 51. These notches 511 and holes 512 are provided to release water vapor generated by the reaction between the heat generating agent 42 and the water 32.

  The blade part 52 is a part that breaks through the water pack 3. As shown in FIG. 2, the blade portion 52 is formed so as to protrude downward from the flat plate portion 51, and is positioned above the central portion 4 a (space) of the heat generating agent pack 4. A central projection 54 is formed on the upper surface 51 b of the flat plate portion 51 coaxially with the blade portion 52. The central protrusion 54 is for evenly transmitting the force to the blade portion 52 when the flat plate portion 51 is pressed.

  As shown in FIG. 2, each pressing protrusion 53 extends downward from the flat plate portion 51. Here, the pressing protrusion 53 is formed in a plate shape, and is supported in contact with the heat generating agent pack 4. Further, a protrusion 53 a is formed on the upper surface 51 b of the flat plate portion 51 at the same position as each pressing protrusion 53. Each protrusion 53a is for evenly transmitting a force to each pressing protrusion 53 when the flat plate portion 51 is pressed.

  The sealing material 6 is attached to the upper surface 2a so that the opening 2b of the container 2 can be sealed. The sealing material 6 is formed using a moisture permeable material (polyethylene or the like) in order to prevent the heat generating agent 42 in the heat generating agent pack 4 in the container 2 from absorbing moisture.

  Next, the procedure for heating the heating object 10 using the heating pack 1 will be described with reference to FIG.

  First, the sealing material 6 is peeled from the container 2 as shown in FIG. Next, the heating object 10 is placed on the bag breaking member 5 as shown in FIG.

  Next, the heating object 10 is pushed in as shown in FIG. Then, the bag breaking member 5 is pushed in, and each pressing projection 53 of the bag breaking member 5 pushes the outer surface 3 a of the water pack 3 through the heat generating agent pack 4. Thereby, the central part 3b of the water pack 3 is pushed up, the central part 3b is pierced by the blade part 52, and the water 32 leaks out.

  Subsequently, when the object to be heated 10 is further pushed in as shown in FIG. 5D, each pressing protrusion 53 of the bag breaking member 5 further pushes the outer surface 3 a of the water pack 3, and the water 32 is discharged from the water pack 3. Extruded. The water 32 penetrates into the heat generating agent pack 4 and reacts with the heat generating agent 42 to generate heat and generate high-temperature water vapor 11. The water vapor 11 rises through the notch 511 and the hole 512 (see FIG. 4) of the bag breaking member 5. Furthermore, the container 2 is filled with the hot water vapor 11 by closing the container 2 with the lid 12 as necessary. The heating object 10 is heated by the heat generated by the heat generating agent 42 and the high temperature steam 11. Although not shown, the lid 12 is provided with a small hole for removing the water vapor 11.

  As described above, the heating pack 1 according to the present embodiment can be heated by placing the heating object 10 in the container 2, and thus can be used independently by itself. Therefore, the heating pack 1 of the present embodiment can heat various objects to be heated as necessary, and can discard only the minimum necessary heating pack 1.

  Moreover, since the heating pack 1 according to the present embodiment can be used independently by itself, it can be stocked, carried and used in various places. Moreover, since this heating pack 1 heats the heating object 10 using a heat generating agent and water, it can be used in places where fire and electricity cannot be used, and elderly people who are worried about handling fire. Can be used with peace of mind for children. Therefore, this heating pack 1 can be sufficiently used even in ordinary households.

  In addition, in this Embodiment, although the heating target object 10 was arrange | positioned in the container 2, when larger than the container 2, you may arrange | position on the container 2. FIG.

  Further, in the heating pack 1 of the present embodiment, the bag breaking member 5 is arranged away from the water pack 3 by arranging the bag breaking member 5 via the heat generating agent pack 4 on the upper side of the water pack 3. This can prevent the bag breaking member 5 from accidentally breaking through the water pack 3 when not in use. Therefore, the heating pack 1 of the present embodiment can improve usability.

  Furthermore, in the heating pack 1 of the present embodiment, the heat generating agent pack 4 is formed in an annular shape, and the blade portion 52 of the bag breaking member 5 is positioned above the central portion 4a (space). This makes it possible for the blade 52 to directly pierce the water pack 3 during use. Therefore, the exothermic agent 42 and the water 32 can be reacted quickly to cause the exothermic agent 42 to quickly generate heat and to quickly generate the high temperature water vapor 11. Therefore, the heating pack 1 of the present embodiment can efficiently heat the heating object 10.

  Furthermore, the heating pack 1 according to the present embodiment is arranged such that each pressing protrusion 53 of the bag breaking member 5 is in indirect contact with the outer surface 3 a of the water pack 3. Thereby, in use, each pressing projection 53 pushes the outer surface 3a of the water pack 3 to push up the central portion 3b, so that the water pack 3 can be efficiently pierced by the blade portion 52. Furthermore, the exothermic agent 42 and the water 32 can be reacted more quickly so that the exothermic agent 42 can generate heat more quickly and the high-temperature water vapor 11 can be generated more quickly. Therefore, the heating pack 1 of the present embodiment can heat the heating object 10 more efficiently.

  Furthermore, as shown in FIG. 2, the heating pack 1 of the present embodiment is provided with a central protrusion 54 and a plurality of protruding portions 53 a on the upper surface 51 b of the flat plate portion 51 of the bag breaking member 5. For this reason, when the heating object 10 is placed on the central protrusion 54 and the plurality of protrusions 53a and the bag breaking member 5 is pushed in, the force is evenly transmitted to the blade 52 and the pressing protrusions 53 of the bag breaking member 5, and therefore the inclination is inclined. However, each pressing projection 53 can reliably press the outer surface 3 a of the water pack 3. As a result, the central portion 3b is reliably pushed up, and the water pack 3 is more efficiently pierced by the blade portion 52, causing the heat generating agent 42 and the water 32 to react more quickly, causing the heat generating agent 42 to generate heat more quickly, and the high temperature steam 11 Can be generated more quickly. Therefore, the heating pack 1 of the present embodiment can heat the heating object 10 more efficiently.
