As shown in FIGS. 1 and 2, the outer box 1 of the package A is formed of a rectangular parallelepiped cardboard box, and has a rectangular frame-shaped peripheral wall upward from the outer peripheral edge of the flat rectangular bottom 11. A rectangular cover piece 13, 13... For closing the upper end opening of the outer box 1 so as to be openable and closable is extended to each of the upper end opening edges of the peripheral wall portion 12. It is installed. The outer box 1 is formed so that oxygen can flow into the outer box 1 through a gap formed at the seam between the cardboards and the cardboard itself.

  Furthermore, an inner box 2 made of foam is disposed in the outer box 1. The inner box 2 is formed in a rectangular parallelepiped shape that is slightly smaller than the outer box 1, and includes a planar rectangular bottom 21 and a rectangular frame-shaped peripheral wall 22 extending upward from the outer peripheral edge of the bottom 21. And a lid 2b that closes the upper end opening of the storage container 2a so that it can be opened and closed. The storage container 2a is used to store the stored items in a portion surrounded by the bottom 21 and the peripheral wall 22 of the storage container 2a. A possible storage part 20 is formed.

  As described above, the inner box 2 is formed to be slightly smaller than the outer box 1, so that the inner box 2 is accommodated in the outer box 1, and the upper end opening of the outer box 1 is the lid piece 13. , 13..., A space B is formed entirely between the outer surface of the inner box 2 and the inner surface of the outer box 1.

  And between the outer surface of the bottom part 21 of the inner box 2 in the said space part B and the inner surface of the bottom part 11 of the outer box 1 which opposes this, the chemical heating element 3 is the bottom part 21 of the inner box 2, and the bottom part of the outer box 1 11 is in contact with the state. That is, the chemical heating element 3 is placed on the inner surface (inner bottom surface) of the bottom 11 of the outer box 1, and the inner box 2 is placed on the chemical heating element 3.

  As the chemical heating element 3, a conventionally known one can be used. For example, a powder mixture is formed by absorbing a salt solution in a mixture of activated carbon and a water retention material, and this powder mixture is mixed with iron powder and aluminum powder. A chemical heating element is formed by enclosing and sealing a metal powder such as a metal powder, and this chemical heating element uses heat generated when the metal powder is oxidized. Oxygen is required for heat generation.

  In the packaging body A of the present invention, the outer box 1 is formed of a cardboard box and oxygen is allowed to flow in from the outside. Therefore, the chemical heating element placed on the inner surface of the bottom 11 of the outer box 1 3 is supplied with oxygen smoothly from the outside of the outer box 1 and reliably generates heat.

  Further, in the storage portion 20 of the inner box 2, a pair of strip-like foam sheets 4, 4 having a fixed length and a fixed width are stacked in a state of being orthogonal to each other at the center in the length direction. The portion is disposed in a state of being located on the inner surface of the bottom 21 of the inner box 2.

  Further, a heat storage body 5 is placed on the inner bottom surface of the storage portion 20 of the inner box 2, that is, on the inner surface of the bottom portion 21 via the foamed sheets 4, 4. It is disposed on the inner bottom surface of the storage portion 20 above the chemical heating element 3. A water absorbent paper 6 is placed on the heat storage body 5.

  In addition, as said heat storage body 5, a conventionally well-known thing can be used, and a heat storage agent is sealed in a plate-shaped hollow container. As such a heat storage agent, for example, an aqueous solution of an inorganic salt such as sodium chloride, ammonium chloride or magnesium chloride, an aqueous alcohol solution such as methanol or ethanol, or a water-soluble polymer is added with a known gelling agent to form a gel. What was formed is mentioned.

  And the space part 20a covered with the foam sheets 4 and 4 is formed in the upper part of the thermal storage body 5 in the storage part 20 of the inner box 2, and fresh goods, such as sea grapes, are formed in this space part 20a. It can store plants such as flowers and florets.

  Next, how to use the package A will be described. First, when the inner box 2 is stored in the outer box 1, the chemical heating element 3 is heated on the inner surface of the bottom 11 of the outer box 1 after the inner box 2 is taken out from the outer box 1. It is placed in a state or a state where heat can be generated.

  Thereafter, the inner box 2 is housed in the outer box 1 in a state of being placed on the chemical heating element 3, and the foam sheets 4, 4, the heat storage body 5 and the water absorbing paper 6 are sequentially placed in the housing part 20 of the inner box 2. Arrange. And after placing storage goods C such as fresh products such as sea grapes and plants on the water absorbent paper 6 in the storage section 20 of the inner box 2, the upper ends of the foam sheets 4 and 4 are overlapped with each other. Thus, the stored item C is covered with the pair of foam sheets 4 and 4. Subsequently, after closing the upper end opening of the storage container 2a of the inner box 2 by the lid 2b, the upper end opening of the outer box 1 is closed by the lid pieces 13, 13. Body A can be obtained. In addition, the extra water | moisture content which adheres to the stored item C or generate | occur | produces from the stored item C is absorbed by the water absorbing paper 6, and the situation where the stored item C is conveyed in the state immersed in water does not generate | occur | produce.

  In the package A, a space B is formed between the outer box 1 and the inner box 2, and a chemical heating element 3 is disposed in the space B. The part B is heated. And the air in the space part B heated by the chemical heating element 3 convects in the space part B, and heats and keeps the inner box 2 as a whole. Since the outer box 1 is formed of a cardboard box, oxygen is smoothly supplied into the space B, and the chemical heating element 3 continues to generate heat for a predetermined time with a sufficient concentration of oxygen.

  At the same time, since the chemical heating element 3 is in contact with the outer surface of the bottom 21 of the inner box 2, the chemical heating element 3 heats the bottom 21 of the inner box 2 by heat conduction, and the heated bottom 21 causes the inner box to be heated. The heat storage body 5 placed on the inner surface of the bottom 21 of the 2 is heated and retains the amount of heat.

  As described above, although the bottom 21 of the inner box 2 is heated by the heat generated by the chemical heating element 3, the heat storage body 5 is interposed between the stored item C and the bottom 21 of the inner box 2, and the chemical heat generation. While the influence of the direct heating by the body 3 on the temperature of the stored item C is mitigated by the presence of the heat storage body 5, the air in the space B is heated by the chemical heating element 3, and this heated air is convected. As a result, the inner box 2 is covered with air heated to an appropriate temperature, so that the heat entering the inner box 2 can be kept uniform. As a result, the product temperature of the stored item C in the inner box 2 is also more uniformly maintained.

  Then, when the chemical heating element 3 elapses for a certain period of time, its calorific value decreases or the heat generation stops. At this time, as described above, the heat storage body 5 is heated by the chemical heating element 3 to maintain the amount of heat, and the inside of the storage portion 20 of the inner box 2 is heated and kept warm by this heat storage body 5. Even after the heat generation of 3 is stopped, the inside of the storage section 20 of the inner box 2 is heated and kept warm by the heat storage body 5. At this time, since the heat storage body 5 is formed of a substance having a large specific heat, the heat storage body 5 is heated to an appropriate temperature without being heated to a high temperature by the chemical heating element 3, and the heated temperature is maintained for a long time. Therefore, the inside of the storage portion 20 of the inner box 2 is kept at an appropriate temperature by the amount of heat accumulated in the heat storage body 5. Moreover, also when the temperature in the storage part 20 of the inner box 2 becomes below the freezing temperature of the heat storage body 5 or the stored item C, the freezing start time of the stored item C can be delayed by the latent heat of the heat storage unit 5.

  In this way, the inner box 2 is heated and kept warm by the heat accumulator 5 after being heated and kept by the chemical heating element 3, and the stored item C stored in the storage portion 20 of the inner box 2 is also at the outside temperature. Regardless, it is kept at an appropriate temperature for a long time, and is transported to a destination without causing deterioration in quality even in long-distance transportation requiring a long time.

  In the package A, the chemical heating element 3 is disposed only between the bottom 21 of the inner box 2 and the bottom 11 of the outer box 1 opposed thereto, and the heat storage body 5 is disposed only on the inner surface of the bottom 21 of the inner box 2. As shown in FIG. 3, the chemical heating element is also provided between the upper surface of the lid 2b of the inner box 2 and the lid pieces 13, 13,. 3 'may be disposed, and a heat accumulator 5' may be disposed between the stored item C stored in the storage portion 20 of the inner box 2 and the inner surface of the lid 2b of the inner box 2 opposite to the stored item C. Good.

  In this way, by arranging the chemical heating elements 3, 3 'and the heat storage bodies 5, 5' on the upper and lower sides of the stored item C stored in the storage unit 20 of the inner box 2, the inner box 2 can be reliably kept warm from above and below, and the stored item C stored in the inner box 2 can be kept warm at a predetermined temperature for a longer time even in a more severe environment.
