Description

The present invention relates to a portable heat insulation jar, and more particularly to a portable heat insulation jar in which the heat insulation property of the rice container is improved in a configuration in which a rice container having a heat insulation structure and a side dish container not having a heat insulation structure are combined and stored in an outer case. About.

Conventionally, portable heat insulation jars (hereinafter referred to as “vertical heat insulation jars”) in which a cylindrical rice container and a vegetable container are stacked in a cylindrical outer case are known, but they are generally bulky. There's a problem.

Therefore, in recent years, portable heat insulation jars (hereinafter referred to as “horizontal heat insulation jars”) that store rice containers and prepared food containers in an exterior case in a state of being adjacent to each other in the horizontal direction have gained popularity.

Generally, a rice container needs to keep the cooked rice for a long time, so a container body with a heat insulation structure composed of a vacuum double container and an upper cover with a heat insulation structure that covers the upper opening of the container body in an openable and closable manner. It has. On the other hand, the side dish container does not have a heat insulation structure.

Although the exterior case is configured by a pouch or the like that is convenient for carrying and has a heat insulating structure, heat dissipation of the rice container cannot be completely prevented because of being carried outdoors.

For this reason, in order to improve the heat retention of a rice container, what provided the heat retention cap which covers the outer periphery of the upper opening part of a container main body from the upper cover of a rice container is proposed.

Registered Utility Model No. 3100210 Japanese Patent No. 4301204

The conventional horizontal portable heat insulation jar is generally smaller in volume than the conventional vertical heat insulation jar, but the outer shape of the outer case is formed horizontally so that it can be carried in a bag such as a bag. It is not always easy to use.

Therefore, the present inventor has formed a rice container and a side dish container so as to be horizontally long in a plan view, and a portable heat insulation jar (hereinafter referred to as “new”) that is stored in an outer case with the side dish container laminated on the rice container. It has been found that the provision of a “longitudinal heat insulation jar”) improves the usability for carrying it in a bag such as a bag because the outer case becomes a so-called book shape.

However, in the case of such a new vertical-type thermal insulation jar, since the side dish container is laminated on the rice container storing hot cooked rice, the heat of the rice may affect the side dish and cause corruption. There are issues that need to be resolved.

In this regard, in order to improve the heat retention and heat insulation of the rice container, a heat retention cap as in Patent Document 1 is helpful, but there is no problem in Patent Document 1 as a horizontal heat retention jar. In the case of a new vertical type heat insulating jar, the heat that has passed through the heat insulating cap may rise and adversely affect the prepared food container.

For this reason, this invention solves the problem peculiar to a new vertical installation type heat insulation jar, and can completely intercept not only the heat insulation heat insulation of a rice container but the heat influence to the vegetable container laminated on it. It is an issue to provide a portable thermal insulation jar.

Furthermore, the present invention provides an inner case for completely shutting off the heat dissipation of the rice container, and at that time, a portable heat insulation jar configured to be able to easily take out the rice container stored in the inner case. The issue is to provide

The present invention provides a portable heat insulation jar that solves the above-mentioned problems, and as a means thereof, a portable heat insulation jar comprising a rice container and a sugar beet container that are detachably stored in an outer case, The rice container and the side dish container are horizontally long in a plan view, and are stored in an outer case in a state in which the side dish container is laminated on the rice container. The rice container includes a container body having a heat insulating structure, and an upper portion of the container body. It consists of a top cover with a heat insulating structure that covers the opening so that it can be opened and closed, and is stored in the inner case so that it can be taken out in a state where the top cover is applied to the container body. A flexible flexible bag main body that forms a heat-insulating storage chamber having a lower opening by hanging a peripheral wall having a heat insulating structure from the bottom, and a lower opening that covers the lower opening of the bag main body so as to be freely opened and closed Said rice container comprising a lid With the upper lid facing the upper wall of the bag body and the bottom of the container body facing the lower lid, the rice container is stored so that it is tightly held by the inner case, with the upper wall facing upward The inner case is housed in the outer case.

In a preferred embodiment of the present invention, the inner case has a base end portion fixed to the inside of the first wall portion with respect to the first wall portion and the second wall portion of the peripheral walls facing the heat insulating storage chamber of the bag body. And an intermediate portion extending from the base end portion and extending along the inner side of the upper wall and the second wall portion, and a distal end portion extending from the intermediate portion and extending along the inner side of the lower lid. It has a long body.

In a further preferred embodiment of the present invention, the lower lid of the inner case includes a covering peripheral wall that is fitted onto the outer peripheral edge of the lower opening of the bag body, and the outer peripheral portion of the lower opening and the inner peripheral portion of the covering peripheral wall A hook-and-loop fastener that allows the mutual attachment and detachment is provided around the front end of the elongate body, and a gripping portion that extends between the outer peripheral edge of the lower opening and the covering peripheral wall and extends to the outside of the inner case is provided. I have.

A lower lid of the inner case is coupled to a second wall portion of the bag body via a hinge, the grip portion is extended toward the outside of the first wall portion of the bag body, and the grip portion is pulled downward. It is preferable to constitute so that the hook-and-loop fastener is separated. Furthermore, it is preferable to provide a knob in a portion facing the grip portion in the upper portion of the bag body.

According to the present invention described in claim 1, a “new vertical-type heat insulation jar” is configured, and the outer case for storing the rice container 2 and the side dish container 3 each having a plan view that is horizontally long is a so-called book shape. Therefore, it is possible to provide an easy-to-use portable heat insulation jar for carrying in a bag such as a bag.

And regarding the heat retaining property of the cooked rice stored in the cooked container 2, the cooked container 2 has a structure in which it is inevitable to radiate the heat of cooked rice from the vicinity of the opening edge 6a of the container body 6, but according to the present invention. And since it is the structure which hold | grips the whole periphery of the rice container 2 in the closely_contact | adhered state by the inner case 11 with high heat insulation heat retention, heat dissipation of cooked rice is suppressed as much as possible.

In particular, the inner case 11 has an opening formed by a lower lid 16 formed on the lower side, and an upper portion of the flexible and flexible bag body 15 having a high heat insulation and heat-retaining property formed integrally and integrally on the upper side. Because the wall 12 and the peripheral wall 13 hold the outer lid from the top lid 7 of the rice container 2 and the opening edge 6a of the container body 6 to the vicinity of the bottom 6b in close contact, the thin opening edge 6a of the container body 6 is temporarily Even if the heat of the cooked rice is going to be released by heat conduction, there is an effect that the heat release is completely cut off and the heat-retaining state of the cooked rice can be maintained for a long time.

According to the second aspect of the present invention, since the elongated body 22 is provided in the heat insulating storage chamber 14 of the bag body 15, the rice container 2 is held in close contact with the flexible bag body 15 having flexibility. There is an effect that the rice container 2 can be easily taken out from the bag main body 15 while being held.

At this time, according to the third and fourth aspects of the present invention, the lower lid 16 that covers the lower opening of the bag body 15 is attached in a detachable manner with the hook-and-loop fasteners 20 and 21, and is long. Since the body 22 is provided with the grip portion 28 that extends between the surface fasteners 20 and 21 and extends outward, the lower lid 16 can be easily and easily opened simply by pulling the grip portion 28 downward. . That is, since the hook-and-loop fasteners 20 and 21 form a non-fixed portion that is not fixed to a portion through which the grip portion 28 is inserted, the non-fixed portion grows when the grip portion 28 is pulled strongly downward. Thus, the lower lid 16 can be easily opened simply by detaching the hook-and-loop fasteners 20 and 21 in the circumferential direction and further pulling the grip portion 28 downward after the detachment.

Then, after the lower lid 16 is opened, the rice container 2 can be easily and easily removed from the lower opening of the bag main body 15 by further pulling the grip portion 28 or the distal end portion 24 of the elongated body 22 downward. Can be withdrawn. Therefore, in order to take out the rice container 2 held in close contact with the bag main body 15, the user does not need a difficult work of grasping and pulling out the vicinity of the bottom 6 b of the container main body 6 with a fingertip or the like. The rice container 2 can be easily taken out from the bag body 15 by a simple operation of pulling the long body 22.

Furthermore, according to the present invention described in claim 5, since the user can hold the picking piece 29 with one hand and pull the long body 22 with another hand, the opening operation of the lower lid 16 and the rice container 2 can be easily taken out.

It is the sectional view on the AA line of FIG. 4 (A). It is a longitudinal cross-sectional view which shows the state which open | released the lower cover of the inner case. It is a longitudinal cross-sectional view which shows the state which took out the rice container from the bag main body of the inner case.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings.

As shown in FIG.1 and FIG.2, the portable heat insulation jar 1 has accommodated the rice container 2, the side dish containers 3 and 3, and the chopstick box 4 in the exterior case 5 so that extraction is possible. The rice container 2 and the side dish containers 3 and 3 are horizontally long in plan view, and are configured to be stored in the outer case 5 in a state where the side dish containers 3 and 3 are stacked on the rice container 2. It is formed in a so-called book shape that is convenient to carry in a bag such as a bag. Thereby, the portable heat insulation jar 1 provides the “new vertical heat insulation jar” as described above.

As shown in FIG. 1, the exterior case 5 includes an opening / closing lid 5b formed by a front wall of a box-shaped case body 5a having a book shape, and the opening / closing lid 5b is attached to the case body 5a by a zipper-type attaching / detaching means 6. The lid is openable and closable by adhering. The opening / closing lid 5b opens the front portion of the case body 5a by being inverted via the hinge portion 5c when the lid is opened.

As shown in FIGS. 2 and 4 (B), the rice container 2 is capable of opening and closing a container body 6 having a heat insulating structure formed of a stainless steel vacuum double container and an upper opening of the container body 6. An upper lid 7 having a heat insulating structure for covering is provided and configured to store hot cooked rice. The upper lid 7 constitutes a synthetic resin lid body in which a heat insulating material is loaded into the hollow interior, and the stopper portion 7a is tightly fitted to the opening portion of the container body 6 and the opening edge 6a of the container body 6 is sealed by packing. To do. Accordingly, the rice container 2 stores the cooked rice in a thermally insulated and heat-insulated state, but as shown in the figure, the vicinity of the opening edge 6a of the container body 6 is formed thinly by the joint of the vacuum double container. Heat release from the rice is unavoidable, although gradually.

As shown in FIG. 2, the side dish container 3 includes a container body 8 that does not have a heat insulation structure, and a lid body 9 that does not have a heat insulation structure that covers the upper opening of the container body 8 so that the upper opening can be opened and closed. It is configured to store side dishes, that is, side dishes. Since the side dish container 3 does not have a heat insulating structure, the cooked side dish is cooled by heat radiation and kept at room temperature. Therefore, the side dish stored in the side dish container 3 is easily affected by heat from the outside. In the case of the illustrated example, the two side dish containers 3 and 3 are stored in the outer case 5 in a state of being stacked on the rice container 2, but the number thereof is not limited.

As shown in FIG. 2, the chopstick box 4 is arranged vertically on the side of the laminated body of the rice container 2 and the side dish container 3 and is detachably fixed by a fixing band 10. The fixed band 10 has, for example, both ends of an elastically stretchable band fixed to the inside of the outer case 5, and the outer peripheral surface of the chopstick box 4 with the chopstick box 4 inserted between both ends of the fixed band 10. To hit.

As shown in FIGS. 2, 3, 4 (A), and 5, the rice container 2 is housed in the inner case 11 in a state where the container body 6 is covered with an upper lid 7 so as to be freely taken out. The inner case 11 is configured to hold the entire outer peripheral surface of the stored rice container 2 in a close contact state, and thus is formed in a shape that is horizontally long in a plan view like the rice container 2.

The inner case 11 includes a bag main body 15 that forms a heat insulating storage chamber 14 having a lower opening by suspending a peripheral wall 13 having a heat insulating structure from the periphery of the upper wall 12 having a heat insulating structure, and the bag main body 15. The lower opening 16 is provided to cover the lower opening of the door so that the lower opening can be freely opened and closed.

Although not shown, the bag body 15 is a series of the upper wall 12 and the peripheral wall 13 made of a flexible flexible heat insulating material that is sewn with a heat insulating material such as a heat insulating fiber sandwiched between two cloth fabrics. It is configured by sewing together. The lower lid 16 may be configured by sewing the same heat insulating material as that of the bag body 15, but is not necessarily required to have high heat insulating properties, and may have normal heat insulating properties. A flat plate portion 17 that covers the lower opening portion, and a belt-shaped covering peripheral wall 18 that stands on the periphery of the flat plate portion 17 are provided.

A pair of first wall portion 13a and second wall portion 13b facing the heat-insulating storage chamber 14 among the horizontally long wall portions of the peripheral wall 13 of the bag body 15 having a horizontally long plan view are shown in FIG. As described above, the lower lid 16 is coupled to the second wall portion 13b via a belt-like hinge 19, and when the covering peripheral wall 18 is externally fitted to the outer peripheral edge of the lower opening portion of the bag body 15, the lower opening portion The surface fasteners 20 and 21 are provided around the outer peripheral portion of the cover and the inner peripheral portion of the covering peripheral wall 18 so as to be detachable from each other. In the case of the illustrated example, the surface fasteners 20 and 21 extending in the circumferential direction are fixed to the outer peripheral portion of the lower opening of the bag body 15 and the inner peripheral portion of the covering peripheral wall 18 except for the portion facing the hinge 19. .

Therefore, as shown in FIGS. 4A and 5, the inner case 11 has the top lid 7 of the rice container 2 facing the upper wall 12 of the bag body 15 and the bottom 6 b of the container body 6 of the rice container 2 is lowered. The rice container 2 is stored in a tightly held state in a posture facing the lid 16, and the rice container 2 is stored in this manner, and as shown in FIG. And stored in the outer case 5. Accordingly, the rice container 2 itself has a structure in which it is inevitable to dissipate the heat of the cooked rice from the vicinity of the opening edge 6a of the container body 6, but the entire circumference of the rice container 2 is insulated and heat-retaining. Since it is held in close contact by the high inner case 11, heat dissipation of the cooked rice is suppressed as much as possible.

In particular, the inner case 11 is formed by forming the opening covered by the lower lid 16 on the lower side, and the upper wall 12 and the peripheral wall 13 of the bag body 15 with high heat insulation and heat retention formed in a series and integrally on the upper side. Since the outer lid from the top lid 7 of the rice container 2 and the opening edge 6a of the container body 6 to the vicinity of the bottom part 6b is held in close contact, the heat of the cooked rice is temporarily caused by the heat conduction of the thin opening edge 6a of the container body 6. Even if you try to release it, you can completely cut off heat dissipation and keep the cooked rice warm for a long time. Incidentally, since the bag body 15 is configured to cover the lower opening with the lower lid 16, the heat insulation and heat retaining property on the lower side is inferior to that on the upper side, but the rice container 2 has the bottom 6 b of the container main body 6. In the vicinity thereof, the thick double heat insulating wall of the vacuum double container is configured to provide a high heat insulating structure, so that the heat of cooked rice is not radiated from that portion.

In this regard, in the drawing, a gap appears between the outer periphery of the rice container 2 and the bag body 15, but as described above, the bag body 15 is provided with a heat insulating material such as a heat insulating fiber between two cloth-made fabrics. It is formed by sewing a flexible and flexible heat insulating material that is sewn and sandwiched, and the rice container 2 is pushed into the heat insulating storage chamber 14 to be brought into close contact with the upper wall 12 and the peripheral wall 13. However, it should be understood that a gap as shown does not actually appear.

As shown in FIGS. 3, 4 </ b> A, and 5, the inner case 11 is provided with a flexible long body 22 in the heat insulating storage chamber 14 of the bag body 15. The long body 22 is made of, for example, a single cloth made of cloth, and is located near the lower opening of the bag main body 15 via a fixing portion 23 such as an adhesive on the inside of the first wall portion 13a. A base end portion 24 that is fixed and extends toward the upper wall 12, a first intermediate portion 25 that extends from the base end portion 24 toward the second wall portion 13b along the upper wall 12, and a second wall portion 13b that extends therefrom. A second intermediate portion 26 extending toward the lower opening, and a distal end portion 27 extending from the second intermediate portion 26 toward the first wall portion 13a along the inner side of the lower lid 16, and the distal end portion 24 includes the lower opening. A gripping portion 28 is provided which extends between the surface fastener 21 fixed to the outer peripheral surface of the inner surface 11 and the surface fastener 20 fixed to the inner peripheral surface of the covering peripheral wall 18 and extends to the outside of the inner case 11.

Accordingly, the hook-and-loop fasteners 20 and 21 are not fixed at a portion where the distal end portion 24 of the elongated body 22 is inserted, but are continuously provided in the circumferential direction of the lower opening edge of the bag body 15 and the covering peripheral wall 18. Therefore, as a whole, the covering peripheral wall 18 can be detachably fixed to the lower opening edge of the bag body 15.

Further, on the upper portion of the bag body 15, a knob 29 formed of, for example, a cloth tape fabric is fixed by fastening or the like. The position where the grip piece 29 is fixed is preferably at a position facing the grip portion 28. In the example shown in the figure, it is the corner portion of the upper wall 12 and the peripheral wall 13, but it may be the upper portion of the upper wall 12 and near the upper end of the peripheral wall 13. Department may be sufficient.

6 and 7 show the operation of the long body 22. As shown in FIG. 5, when the rice container 2 is pushed into and stored in the bag body 15 and the gripping portion 28 is strongly pulled downward while being covered with the lower lid 16, as shown in FIG. 21 can be released and the lower lid 16 can be opened. Therefore, the user does not need a complicated work of inserting a fingertip or the like inside the covering peripheral wall 18 and detaching the hook-and-loop fasteners 20 and 21 in the circumferential direction. Since the hook-and-loop fasteners 20 and 21 form a non-fixed portion that is not fixed to the portion through which the grip portion 28 is inserted, the non-fixed portion is grown when the grip portion 28 is pulled strongly downward. The lower lid 16 can be opened by detaching the hook-and-loop fasteners 20 and 21 in the circumferential direction and further pulling the grip portion 28 downward after the detachment.

When the user pulls the gripping portion 28 downward, if the gripping piece 29 is gripped with one hand and the gripping portion 28 is pulled with another hand, the opening operation of the lower lid 16 is facilitated.

After the lower lid 16 is opened, if the portion of the grip portion 28 or the distal end portion 24 of the elongated body 22 is further pulled downward, the rice container 2 is moved to the lower opening portion of the bag body 15 as shown in FIG. It is taken out while projecting from the lower opening. Therefore, in order to take out the rice container 2 held in close contact with the bag main body 15, the user does not need a difficult work of grasping and pulling out the vicinity of the bottom 6 b of the container main body 6 with a fingertip or the like. . The rice container 2 can be easily pulled out from the bag body 15 by a simple operation of pulling the long body 22.

Also in this case, the user can easily take out the rice container 2 by holding the picking piece 29 with one hand and pulling the long body 22 with another hand.

When the user stores the cooked rice 2 in the bag main body 15 after storing the cooked rice in the cooked container 2, the cooked rice container 2 with the elongated body 22 disposed inside the heat insulating storage chamber 14 as described above. May be pushed into the heat insulating storage chamber 14 and covered with the lower lid 16.
