Description

[Technical field]

[0001] The present invention relates to a heated storage container. [Background technology]

[0002] In the event of a disaster or outdoors, a small amount of water can be added to a heat generating agent whose main components are calcium oxide or aluminum powder to generate heat through a chemical reaction, allowing food and drink to be warmed or water to be boiled.

[0003] A heating pack that uses such a heat generating agent for heating is described in, for example, Patent Document 1. The heating pack described in Patent Document 1 has an exterior body and an inner body that is accommodated inside the exterior body to form an enclosed space between the exterior body and the inner body, and that accommodates food and drink inside. The enclosed space is provided with a water-permeable heat generating agent container that accommodates a heat generating agent that reacts with water to generate heat, and a reaction water container that accommodates reaction water to react with the heat generating agent and is opened under the action of a predetermined pressure to release the reaction water to the outside. With this configuration, when food and drink are set in the inner body, the reaction water container can be opened, for example, by tapping with a hand, to heat the food and drink.

[0004] [Patent Document 1] JP 2018-070224 A Summary of the Invention [Problem to be solved by the invention]

[0005] However, the heating pack described in Patent Document 1 is a pouch type, and therefore has a small gusset, and although it can store food and drink of the same size as canned goods or retort packs, it cannot store food and drink such as boxed lunches, etc. In addition, even if the food and drink is canned goods or retort packs, it is difficult to store multiple items at once.

[0006] In addition, commercially available heating packs are equipped with a wire fastener that can open and close the storage opening for storing food and drink. Although heating packs can withstand multiple heatings, repeated heating dozens to hundreds of times can cause the wire fastener to deteriorate, leading to an open storage opening and reduced heating efficiency, or leakage of reaction water that has reacted with the exothermic agent. The reaction water is highly alkaline because it is made by dissolving calcium oxide and aluminum powder, and may cause chemical burns if it comes into contact with the skin.

[0007] In addition, although heating packs can be used multiple times as mentioned above, some users mistakenly believe that they are disposable and use a new heating pack every time they need to heat something up. In particular, if many heating packs are used in evacuation shelters, etc., there is a problem of a large amount of plastic waste being generated.

[0008] The present invention has been made in consideration of the above-mentioned problems, and has as its main object to provide a heat preservation container that can preserve food and drink and can repeatedly heat the food and drink. [Means for solving the problem]

[0009] The heat preservation container of the present invention comprises an outer container having a bottomed cylindrical shape, a first storage space capable of storing a heat generating agent therein, and a first fringe provided around an opening periphery that forms the first storage space; an inner container that is capable of being placed in the first storage space, a bottomed cylindrical shape, a second storage space capable of storing food and drink therein, and a second fringe provided around an opening periphery that forms the second storage space; a lid that is detachably placed on the inner container and seals the second storage space; and a cover that seals the inner container between the first storage space and the outer container. and a sealing member that brings the first fringe and the second fringe into close contact to seal the first storage space when the first fringe is arranged in such a manner that the first fringe and the second fringe are ...

[0010] With the above-mentioned configuration, the heating storage container of the present invention can be stored with a heat generating agent stored in the first storage space and food and drink stored in the second storage space, so it can also be used as a disaster prevention item. In other words, it can be used as a storage container in normal times, and in the event of an emergency, it can be used as a heating container that easily heats food and drink.

[0011] Furthermore, since the second storage space for storing food and drink is constituted by a cylindrical inner container with a bottom, it is possible to store a lunch box or multiple items of food and drink.

[0012] Furthermore, since the container is provided with a sealing member that seals the first storage space by tightly contacting the first fringe and the second fringe, the heating efficiency can be maintained even if the container is repeatedly used for heating. Also, the heating storage container of the present invention that can store food can be used for purposes other than heating, so it is not accidentally thrown away.

[0013] When water is added to the exothermic agent to heat the food or drink by the exothermic reaction, high-temperature steam continues to be emitted for a while, and the high temperature state is maintained even after the steam emission has stopped. Therefore, there is a possibility of getting burned when trying to remove the food or drink during heating or immediately after heating. As a result, in the past, the food or drink could not be removed until some time had passed after the exothermic reaction had ended. However, since the heat storage container of the present invention is provided with a second handle part on the inner container, if the second handle part of the inner container is lifted and removed from the outer container, the food or drink contained in the inner container can be safely removed while being kept away from the exothermic agent contained in the outer container. In addition, since the outer container is also provided with a first handle part, the heat storage container of the present invention can be moved by holding the first and second handle parts even during heating or immediately after heating.

[0014] In addition, since the first handle portion and the second handle portion are arranged so that they do not overlap at least partially, when it is desired to grip only the second handle portion, it is possible to easily grip only the second handle portion.

[0015] A specific aspect of the heating storage container of the present invention is characterized in that the first handle portion has a gap in a part of the longitudinal direction extending along the opening periphery forming the first storage space, and the second handle portion is positioned in the gap without overlapping with the first handle portion. Effect of the Invention

[0016] According to the present invention, a heating storage container can be realized that can store heat generating agents and food and drink, can be used repeatedly without being disposable, and can allow food and drink to be safely removed even after heating.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0018] An embodiment of the heat storage container of the present invention will be described in detail below with reference to the drawings. In this description, common parts are given common reference symbols throughout the drawings unless otherwise specified. In addition, in the drawings, the elements of each embodiment are not necessarily shown to scale. In addition, some symbols may be omitted to make each drawing easier to see.

[0019] As shown in Figures 1 to 7, the heated storage container 1 of this embodiment comprises an outer container 2 capable of containing a heat generating agent, an inner container 3 placed inside the outer container 2 and capable of containing food and beverages, and a lid body 4 removably arranged on the inner container 3.

[0020] 2 and 6, the outer container 2 is in the form of a cylinder with a bottom, and is provided with a first storage space 5 capable of storing a heat generating agent therein. In this embodiment, the outer container 2 is in the form of a square cylinder, and is configured so that the opening width narrows toward the bottom. The outer container 2 can be made of a resin material such as polypropylene.

[0021] A first fringe 6 is provided on the periphery of the opening that forms the first housing space 5 of the outer container 2. The first fringe 6 is provided with a pair of first handle portions 8 that extend outward at positions facing each other across the opening that forms the first housing space 5. A groove is formed in the first fringe 6 in the circumferential direction, and a sealing member 7 is disposed in this groove to tightly contact the first fringe 6 and a second fringe 12 (described later) to seal the first housing space 5. In this embodiment, a seal material such as an O-ring is used.

[0022] The first handle portion 8 has a predetermined thickness and is configured as a rectangle whose longitudinal direction is a direction extending along the periphery of the opening that forms the first housing space 5, and is configured to be integrated with the first fringe 6. A gap 9 is formed in the approximate center of the first handle portion 8 in the longitudinal direction.

[0023] As shown in Fig. 3 and Fig. 7, the inner container 3 is in the form of a cylinder with a bottom, and is provided with a second storage space 10 capable of storing food therein. In this embodiment, the inner container 3 is in the form of a rectangular cylinder, and is configured so that the opening width narrows toward the bottom. The height from the opening end of the inner container 3 to the bottom is configured to be smaller than the height from the opening end to the bottom of the outer container 2. Therefore, as shown in Fig. 5, when the inner container 3 is placed inside the outer container 2, a first storage space 5 is provided between the bottom of the inner container 3 and the bottom of the outer container 2. The inner container 3 can be made of a resin material such as polypropylene.

[0024] 7, a plurality of holes 11 are formed in the bottom surface of the inner container 3, and in this embodiment, the circular holes 11 are arranged in a lattice pattern. The size of each hole 11 is preferably about 3 mm to 5 mm. The size of each hole 11 may be the same or different.

[0025] A second fringe 12 is provided on the periphery of the opening that forms the second storage space 10 of the inner container 3. The second fringe 12 is provided at the same position as the first handle portion 8, across the opening that forms the second storage space 10, and is provided with a pair of second handle portions 13 that extend outward. The second fringe 12 also has a protrusion 14 formed in the circumferential direction for tight contact with the lid body 4, which will be described later.

[0026] The second handle portion 13 has a predetermined thickness and is configured as a rectangle whose longitudinal direction is a direction extending along the periphery of the opening that forms the second storage space 10, and is configured to be integrated with the second fringe 12. The first handle portion 8 and the second handle portion 13 have the same length in the longitudinal direction and the lateral direction, so that the first handle portion 8 and the second handle portion 13 are arranged to overlap each other except for the gap 9 provided in the first handle portion 8.

[0027] The lid 4 is detachably disposed on the inner container 3 and seals the second storage space 10. As shown in Fig. 4, a recess is provided on the periphery of the rear surface of the lid 4 to fit with the protrusion 14 of the second fringe 12, and this appears as a protrusion 21 on the surface of the lid 4. A substantially rectangular raised portion 22 is provided in the approximate center of the lid 4, and multiple steam holes 23 are provided in this raised portion 22. As shown in Fig. 5, the lid 4 seals the second storage space 10 by fitting the protrusion 14 of the inner container 3 with the protrusion 21. The lid 4 can be made of a resin material such as polypropylene.

[0028] A usage mode of the heat storage container 1 of this embodiment configured as described above will be described below.

[0029] The heating storage container 1 of this embodiment can store a heat generating agent in the first storage space 5 and food and drink in the second storage space 10, and is therefore normally used as a storage container for storing these items.

[0030] On the other hand, in an emergency disaster or in an outdoor environment where gas cannot be used or where it is difficult to start a fire, the heat storage container 1 of the present embodiment can be used as a heating container. The use as a heating container will be described below.

[0031] First, the inner container 3 is removed from the outer container 2, and a small amount of water is added to the heat generating agent, whose main components are calcium oxide and aluminum powder, contained in the first storage space 5 of the outer container 2. Heat begins to be generated in the first storage space 5 through a chemical reaction.

[0032] In this state, food or drink is contained in the second storage space 10, and the inner container 3 with the lid 4 attached is attached to the inside of the outer container 2. At this time, as shown in Fig. 5, since the height from the opening end to the bottom of the inner container 3 is configured to be smaller than the height from the opening end to the bottom of the outer container 2, the inner container 3 can be attached to the outer container 2 while maintaining the first storage space 5 in which the heat generating agent and the reaction water that reacted with the heat generating agent are contained.

[0033] Here, when the inner container 3 is attached to the outer container 2, the first fringe 6 of the outer container 2 and the second fringe 12 of the inner container 3 come into contact with each other, and a sealing member 7 is arranged on the first fringe 6 of the outer container 2. Therefore, the second fringe 12 of the inner container 3 comes into contact with the first fringe 6 with the sealing member 7 crushed by the weight of the inner container 3 and the food and drink contained in the second storage space 10, so that the first fringe 6 and the second fringe 12 come into close contact with each other, thereby sealing the first storage space 5.

[0034] Since the first storage space 5 is sealed, high-temperature steam generated by the exothermic reaction moves from a plurality of holes 11 formed in the bottom surface of the inner container 3 to the second storage space 10. As a result, the food and drink stored in the second storage space 10 is heated by the high-temperature steam. In addition, the lid 4 that seals the inner container 3 is provided with a steam hole 23. Therefore, the high-temperature steam that has moved to the second storage space 10 flows out from the steam hole 23 to the outside.

[0035] The heating storage container 1 of the present embodiment configured as described above can be used as a storage container under normal circumstances with a heat generating agent stored in the first storage space 5 and food and drink stored in the second storage space 10. Therefore, it can also be used as a disaster prevention item, and in the event of an emergency, food and drink can be easily heated with just the heating storage container 1 of the present embodiment and a small amount of water. In addition, since it can be used as a storage container as described above, it is not accidentally thrown away, and an environmentally friendly product can be realized.

[0036] Furthermore, since the inner container 3 is configured as a cylinder with a bottom, food and drink such as a lunch box can be stored in the second storage space 10 without tilting it, and multiple cans or retort packs can also be stored.

[0037] Furthermore, the first fringe 6 and the second fringe 12 are sealed by a sealing member 7. Since the sealing member 7 is disposed on the first fringe 6 which is not directly exposed to high-temperature steam, deterioration can be prevented even if the fringe is repeatedly heated and used, and heating efficiency can be maintained.

[0038] Even when the exothermic agent is heating, the heat preservation container 1 of this embodiment can be moved by grasping the first handle portion 8 and the second handle portion 13. After heating, the inner container 3 can be removed from the outer container 2 by grasping the second handle portion 13, and the food and drink contained in the inner container 3 can be safely taken out.

[0039] In addition, in this embodiment, the first handle portion 8 and the second handle portion 13 are arranged to overlap except for the gap 9 provided in the first handle portion 8, so that when a user wants to move the heating storage container 1 of this embodiment, he or she can intuitively grasp the first handle portion 8 and the second handle portion 13.

[0040] In addition, since a gap 9 is provided where the first handle portion 8 and the second handle portion 13 do not overlap, a user can easily grasp the second handle portion 13 in the gap 9 where the first handle portion 8 and the second handle portion 13 do not overlap, and remove the inner container 3 from the outer container 2. Therefore, even immediately after the emission of steam due to the exothermic reaction has finished, the inner container 3 can be removed from the outer container 2, and the food and drink contained in the inner container 3 can be separated from the exothermic agent contained in the outer container 2, thereby allowing the food and drink to be taken out.

[0041] The present invention is not limited to the above-described embodiments.

[0042] For example, the first handle portion and the second handle portion may be configured so as not to overlap at all, allowing the user to easily select and grip the second handle portion.

[0043] The present invention can be modified in various ways without departing from the spirit of the invention. [Explanation of symbols]
