Description

  The present invention relates to a lunch jar.

  Launchers of the type that simultaneously contain multiple small containers, such as a miso soup container, a rice container that contains rice, and a vegetable container that contains side dishes, are stacked in multiple stages above and below. Then, the temperature of the food contained in each small container is kept for a certain period of time by being housed in a housing part having a heat insulating structure and covered.

  Conventionally, in order to improve the heat retaining property of such a launcher, various heat insulating structures have been proposed for the lid and the small container as well as the housing.

  By the way, in the above-described launcher, when the applicant realizes cost reduction by simplifying the heat insulating structure of the lid and the small container, the cooking material accommodated in the small container is formed between the inner surface of the accommodating portion and the outer surface of the small container. The air in the gap is warmed, and this warm air (warm air) rises in the gap between the inner surface of the housing part and the outer surface of the small container, but the air that has risen through this gap (warm air) is cooled on the lid side, Along with the problem that the cooking material contained in each small container is easy to cool, the cooking material accommodated in the lower small container warms the air in the gap between the inner surface of the accommodating portion and the outer surface of the lower small container. When the warm air (warm air) in the gap between the inner surface and the lower small container outer surface rises to the inner surface of the housing portion and the upper small container outer surface, the cooking material of the upper small container is heated by this warm air, for example, Fill the lower small container with warm rice, and the upper small container with pickles and Ikuno When packed laden side dishes, etc., side dishes of the upper has been found that to occur a disadvantage arises in that the heat.

  In other words, the launcher that achieves cost reduction by simplifying the heat insulating structure of the lid and the small container has a problem that the heat insulation property of the cooking material stored in the small container is not sufficient.

  The present invention has solved this problem in view of the above-mentioned problems, and is an extremely excellent lunch that can improve the heat retention of the cooking material contained in a small container simply by providing a flat plate that can be easily assembled with a simple configuration. Jar is provided.

  The gist of the present invention will be described with reference to the accompanying drawings.

  Embodiments of the present invention that are considered suitable (how to carry out the invention) will be briefly described with reference to the drawings, illustrating the operation of the present invention.

  A flat plate 5 is disposed in the housing portion 1 in which a plurality of small containers 4 are housed in a stacked state of a plurality of stages.

At this time, the flat plate 5 is configured to have a diameter larger than the inner diameter of the housing portion 1 and an outer peripheral edge portion formed in a tapered shape with a material having elasticity that can be flexibly flexible or elastically contacted. When the flat plate 5 is disposed above the gap formed between the inner surface of the housing portion 1 and the outer surface of the small container 4, the outer peripheral edge portion of the flat plate 5 is bent and flexible or elastically pressed against the inner surface of the housing portion 1. It contacts closely with the inner surface of the housing part 1 while being in contact , and closes the gap between the inner surface of the housing part 1 and the outer surface of the small container 4 from above.

  Therefore, the warm air is confined in the gap between the inner surface of the storage portion 1 and the outer surface of the small container 4, and accordingly, the storage portion 1 that stores a plurality of small containers 4 that store cooking materials such as miso soup and rice, and this storage The heat retaining property of the container 3 including the lid portion 2 that closes the upper opening of the portion 1 is improved.

  That is, when the heat insulating structure of the lid portion 2 and the small container 4 is simplified and the cost is reduced as in the prior art, the cooking material accommodated in the small container 4 causes a gap between the inner surface of the accommodating portion 1 and the outer surface of the small container 4. This warm air (warm air) rises in the gap between the inner surface of the container 1 and the outer surface of the small container 4, but the air (warm air) that has risen through this gap is cooled on the lid 2 side. Therefore, the cooking material contained in each small container 4 may be easily cooled. In this respect, in the present invention, the flat plate 5 closes the gap between the inner surface of the container 1 and the outer surface of the small container 4 from above, and traps warm air in the gap between the inner surface of the container 1 and the outer surface of the small container 4. This warm air is not cooled on the lid 2 side, so that it can be easily assembled with a simple structure without providing an expensive or complicated heat insulating structure for the housing 1, lid 2 and small container 4. The heat insulation property of the cooking material accommodated in the small container 4 is improved only by providing the flat plate 5.

  Further, for example, when the flat plate 5 is configured to be placed between the small container 4 and the small container 4 that are stacked and accommodated in the upper and lower stages, the inner surface of the accommodating portion 1 and the lower small container 4 are arranged. By confining the warm air in the gap with the outer surface, the heat retaining property of the cooking material accommodated in the lower small container 4 can be easily improved, and this warm air is placed in the gap between the inner surface of the accommodating portion 1 and the outer surface of the upper small container 4. The cooking material stored in the upper small container 4 is not heated by the warm air.

  That is, if hot miso soup or warm rice is stored in the lower small container 4 and a side dish containing pickles or raw vegetables is stored in the upper small container 4, the miso soup or rice is kept warm. On the other hand, the hot miso soup or warm rice warms the side dishes containing the pickles and raw vegetables contained in the upper small container 4 more than necessary, and the side dishes have a certain temperature (room temperature). There was a case that could not be kept. In this respect, according to the present invention, the flat plate 5 closes the gap between the inner surface of the storage portion 1 and the outer surface of the small container 4 for storing hot miso soup and warm rice on the lower side, so that the inner surface and the lower side of the storage portion 1 are closed. In order to confine the warm air in the gap between the outer surface of the small container 4 for storing hot miso soup and warm rice, only the lower small container 4 reliably heats the soup and rice while it is accommodated in the lower small container 4 The hot air of the hot miso soup and warm rice does not rise to the gap between the inner surface of the container 1 and the outer surface of the upper small container 4, so that the side dishes of the upper small container 4 are heated more than necessary by the warm air. For example, in order to avoid the heat of the side dishes, the side dishes are stored in hot miso soup and warm rice without the side dishes being put into the container 3 and the side dishes being cooled excessively by the cold outside air. Even at the right temperature The lunch jar that may be lifting.

  In addition, for example, the flat plate 5 is placed on the upper portion of the small container 4 disposed on the lower side, and the gap between the small container 4 and the inner surface of the housing portion 1 is closed from above to lower the lower container 4. When the small container 4 is configured to prevent the warm air of the small container 4 from being transmitted upward to the periphery of the upper small container 4, the small container 4 is biased to the upper part of the small container 4 when the small containers 4 are stacked in order from the bottom. The small container 4 and the small container 4 are heat-insulated and separated at a desired position by a simple means of placing and arranging the flat plate 5 and can be easily attached / detached at a desired position without providing a special locking structure or detachable structure. It can be set freely, and the above-mentioned heat insulation and the warm air cutoff upward are simplified and ensured.

Further, for example, the flat plate 5 is made of a flexible material and has a diameter larger than the inner diameter of the housing portion 1. When the flat plate 5 is attached from the upper opening into the housing portion 1, A configuration in which the outer peripheral edge of the flat plate 5 is bent and elastically brought into contact with the inner surface of the housing portion 1 so as to close the gap between the inner surface of the housing portion 1 and the outer surface of the small container 4 from above. In this case, since the outer peripheral edge of the flat plate 5 is bent and elastically contacts the inner surface of the housing portion 1, the handleability when the flat plate 5 is attached to and detached from the housing portion 1 is improved. The outer peripheral edge part of the flat plate 5 and the inner surface of the accommodating part 1 are easily adhered.

  Further, for example, when the flat plate 5 is made of a material having flexibility, and the core material 6 for reinforcement or shape retention is embedded or attached, the flat plate 5 is formed of the small container 4 and the small container. 4 or close to the upper part of the small container 4 to tightly insulate the gap between the small container 4 and the small container 4 or the gap between the inner surface of the container 1 and the outer surface of the small container 4 from above, and the core 6 Since the flat plate 5 is reinforced and retained and is not deformed during attachment or removal, the handleability is improved and the durability is also improved.

  Further, when the flat plate 5 is configured in a ring shape, not only can the material of the hollow portion be saved and the cost can be reduced, but also the attachment and removal can be further performed by grasping the inner edge of the ring-shaped flat plate 5. It becomes easy.

  Specifically, a lidless main body 41a for storing miso soup, a soup container 4A comprising a lid 42a that can freely open and close an upper opening of the main body, a lidless main body 41b for storing rice, and the main body The upper opening is configured with a rice container 4B composed of a lid 42b that can be opened and closed, a non-lid main body 41c for storing side dishes, and a vegetable container 4C composed of a lid 42c that can be opened and closed. ing.

  The flat plate 5 is a ring-shaped board having a diameter equal to or larger than the inner diameter of the housing portion 1, and by making such a ring-shaped shape, the inner edge of the ring is grasped, Attachment and removal to / from the housing part 1 can be performed easily.

  Specifically, the ring-shaped flat plate 5 is formed of a flexible material such as silicon rubber. Therefore, the outer peripheral edge portion of the flat plate has flexibility that can be bent or elastically contacted. Therefore, the flat plate 5 of this embodiment is formed on the inner surface of the housing portion 1 as shown in FIG. Needless to say, it can be flexibly flexible or elastically contacted, and is in close contact with the upper side of the small container 4 or between the small container 4 and the small container 4.

More specifically, the flat plate 5 is formed in a tapered shape whose peripheral edge becomes narrower toward the edge in the plan view. Therefore, the flexibility of the peripheral edge of the flat plate 5 is improved, the handleability when being attached to and detached from the accommodating portion 1 is improved, and the outer peripheral edge portion of the flat plate 5 is more easily adhered to the inner surface of the accommodating portion 1. To do.

  Further, as shown in FIGS. 3 and 4, the flat plate 5 has a structure in which a core material 6 for reinforcement or shape retention is embedded or attached.

  Specifically, the core material 6 is formed of a resin such as PP (polypropylene), PE (polyethylene), or PET (polyethylene terephthalate) in a ring shape, and the core material 6 is formed as shown in FIG. It arrange | positions in the state which can be inserted and removed from the inner peripheral part of the flat plate 5. As shown in FIG.

  Accordingly, the core material 6 reinforces and retains the flat plate 5, and the durability of the flat plate 5 is improved and is not easily deformed. Therefore, the handling property is further improved when attaching to and removing from the housing portion 1. It becomes.

  Although the present embodiment shows the case where the core material 6 is disposed so as to be sandwiched, the core material 6 may be disposed so as to be embedded therein, in which case the core material is disposed. Since 6 and the flat plate 5 are integrated, it is easy to handle.

  In the present embodiment, the flat plate 5 is formed in a ring shape, but instead of the ring shape, a handle 7 is provided at a substantially central portion of the upper surface of the flat plate 5 as shown in FIGS. In this case, the flat plate 5 may be disposed so that the core member 6 is embedded inside or has a thickness sufficient to maintain the shape-retaining property. Is disposed in a portion where the small container 4 and the small container 4 overlap each other, the heat insulation between the small containers 4 is improved as compared with the ring-shaped flat plate 5, and the heat retention of the small container 4 is further improved. The ring-shaped flat plate 5 is preferably used in consideration of the necessity of forming the handle 7 and the reduction of the material cost of the hollow portion in consideration of the formability, mass productivity, cost and the like.

  In addition, although the present Example showed the case where the said flat plate 5 was arrange | positioned in one place between several small containers 4, as shown in FIG. 7, the small flat plate 5 piled up the flat plate 5 in two steps. Even in the case where one container is disposed between the containers 4, as in the present embodiment, the heat retaining property of the small container 4 below the flat plate 5 is easily improved, and the warm air of the small container 4 on the lower side is also improved. Thus, the cooking material accommodated in the upper small container 4 is not heated.

  FIG. 8 illustrates the case where the flat plate 5 is disposed at a plurality of locations between the plurality of small containers 4.

  That is, when the flat plate 5 is placed on the upper part of all the small containers 4 stacked in a plurality of stages, the gap between the inner surface of the storage unit 1 and the outer surface of each small container 4 is closed from above. The heat retention of each small container 4 is improved.
