Description

  The present invention relates to an insulated transport container capable of transporting an object to be kept warm in an insulated state.

  In places where large quantities of food and foodstuffs need to be transported, such as lunch centers and restaurants, insulated transport containers (insulated transportable food containers / insulated transportable food cans) are often used (for example, the following). See Patent Document 1). Such a heat-insulated transport container has a bottom portion capable of supporting the object to be kept warm from below, and a heat-insulating structure having a side portion that is erected from the bottom portion, has an opening at the upper end side, and has a larger cross-sectional area than the bottom portion. A container body, a fitting portion that can be fitted into the opening, and a lid having a heat insulating structure having an engaging portion that can be engaged with a bottom portion of the container body in another insulated transport container are provided.

JP 2004-337518 A

  In the above structure, if the container body of the other heat-insulated transport container that houses the heat-insulating object is stacked on the container body that houses the heat-insulated object without interposing the lid, the container body of the other heat-insulated transport container may be stacked. After taking out the object to be kept warm, it is possible to immediately take out the object to be kept warm from the container body simply by removing the container body of another insulated transport container. For this reason, it is possible to carry the product in a compact and light weight and to perform the operation easily.

  However, in the above conventional technique, when the container body of another heat-insulated transport container is stacked on the container body without a lid interposed therebetween, the container body of the other heat-insulated transport container is deeply inserted into the container body. Therefore, the accommodation volume of the container body located below is too small, and the heat retention target cannot be sufficiently inserted, and the transport efficiency and the work efficiency deteriorate.

  In view of the above situation, there has been a demand for a heat-insulating transport container having a reasonable structure capable of storing a sufficient amount of heat-retaining objects in a stacked state while maintaining the heat-retaining state of the heat-retaining objects in a favorable state.

The heat-insulating transport container according to the present invention,
A bottom portion capable of supporting the object to be kept warm from below, and a container body having a heat insulating structure having a side portion that is provided upright from the bottom and has an opening at an upper end side and a cross-sectional area larger than the bottom portion,
A fitting portion capable of fitting to the opening, and a lid of a heat insulating structure having an engaging portion capable of engaging the bottom portion of the container body in another insulated transport container,
The vertical dimension in which the bottom of the other heat-insulated transport container can enter the opening is smaller than the height of the side part.

According to the present invention, a single form in which a lid body is simply attached to a container body, a stacking form in which a container body of another insulated transport container is stacked on a lid body attached to a container body, without interposing a lid body In this case, it is possible to selectively use a non-stacked form in which a container body of another heat-insulated transport container is stacked on the container body, which is excellent in convenience.
Furthermore, the vertical dimension in which the bottom of another heat-insulated transport container can enter the opening of the container main body is smaller than the height dimension of the side of the container main body. Erosion of the container body of the container body located in the other insulated transport container is suppressed, the accommodation volume of the container body located below is sufficiently ensured, and the object to be heated is sufficiently stored in the container body. It can be inserted and transported.
Therefore, according to the present invention, it is possible to configure a heat-insulating transport container having a reasonable structure that can store a sufficient amount of heat-retaining objects in a stacked state while maintaining the heat-retaining state of the heat-retaining objects in a favorable state.

In the above configuration,
It is preferable that the thickness of the heat insulating space of the lid is larger than the thickness of the heat insulating space of the bottom of the container body.

  According to this configuration, in the stack configuration with the lid, the transfer of heat between the heat insulation target accommodated in the container body of the other heat-insulating transport container and the heat insulation target accommodated in the lower container body is performed in the heat-insulating space. The lid having a large thickness dimension can be suitably suppressed, and the thermal insulation state of the thermal insulation target housed in each heat-insulating transport container can be favorably maintained.

In the above configuration,
It is preferable that the thickness dimension of the heat insulating space at the side part is smaller than the thickness dimension of the heat insulating space at the bottom part.

  According to this configuration, the heat insulation performance can be sufficiently ensured even if the heat insulation space on the side where the heat transfer by the heat insulation target is smaller than that of the bottom of the heat insulation target is somewhat thin. Thus, a structure having a compact lateral dimension can be realized.

Hereinafter, an embodiment which is an example of the present invention will be described in detail with reference to the accompanying drawings.
In this embodiment, as shown in FIGS. 1 to 9, the adiabatic transport container is a single form in which the lid 2 is simply attached to the container body 1, and <2> as shown in FIGS. In addition, a stack configuration in which a container body 1 of another heat-insulated transport container is stacked on a lid body 2 attached to the container body 1 (for example, particularly suitable when the temperature difference between the upper and lower heat insulation objects is large), <3> As shown in FIGS. 16 to 21, the container body 1 of another heat-insulated transport container is stacked on the container body 1 without the lid 2 interposed therebetween (for example, the temperature of the upper and lower heat-retention objects). This is particularly suitable when the difference is small).

<Structure of insulated transport container>
As shown in FIGS. 1 to 9 and the like, a thermally insulated transport container includes a container body 1 having a heat-insulating structure having a predetermined storage volume for storing a heat-retaining object such as food or foodstuff that needs to be kept warm or cold, and a container. And a lid 2 having a heat insulating structure removably fitted to the opening 11 d located on the upper end side of the main body 1.

  The container main body 1 has a bottom portion 11a capable of supporting the object to be kept warm from below, and a side portion 11c which is erected from the bottom portion 11a and provided with an opening 11d at an upper end side and has a larger cross-sectional area than the bottom portion 11a. I have. The lid 2 has a fitting portion 21a that can be fitted into the opening 11d of the container main body 1, and an engaging portion 20 that can be engaged with the bottom 11a of the container main body 1 in another insulated transport container. .

  The engaging portion 20 includes a convex portion 23, a first engaging convex portion 22a, and a second engaging convex portion 22b formed on the upper surface portion 21d of the lid 2 (each reference numeral in the drawing indicates (20)). Are shown side by side).

  The container body 1 forms a heat insulating space at a predetermined interval between the inner container 1a having a rectangular shape in a top view and a bottom portion and a side portion of the inner container 1a, which forms a housing space having a predetermined depth. And an outer container 1b having an opening edge located on the upper end side integrally joined to an upper edge opening edge of the inner container 1a.

  As shown in FIGS. 7 to 9 and the like, the vertical and horizontal outer diameters of the bottom 11a of the container body 1 are smaller by a predetermined size than the vertical and horizontal outer diameters of the side 11c. Have been. In addition, a portion extending from the outer peripheral end of the bottom 11a of the container body 1 to the outer periphery of the lower end of the side portion 11c is formed with an engaging step portion 11b having a small round surface and bent outward in the horizontal direction. ing. As shown in FIG. 21, the outer peripheral corner surface of the engaging step portion 11b is an engaging surface to the opening 11d of the container body 1 in another insulated transport container in the lidless stack configuration.

  The heat insulating space formed between the inner container 1a and the outer container 1b in the container main body 1 is formed such that the bottom portion 11a and the side portion 11c of the container main body 1 have basically the same distance. However, in a portion continuous from the outer peripheral side of the bottom portion 11a to the engagement step portion 11b, the curvature of the bent portion on the inner container 1a side is made relatively small (gradual), so that the separation dimension is slightly reduced. . This is because heat transfer is small on the outer peripheral side (below the engaging step 11b) of the bottom 11a that is bent upward, because it does not come into contact with the container body 1 of another insulated transport container. In addition, this is because not only a sharply angled stepped portion is not formed in the container main body 1 but also a large accommodation volume in the container main body 1 can be secured even if a little.

  In the heat insulating space between the inner container 1a and the outer container 1b in the container main body 1, a second heat insulating material 1c at the bottom portion 11a and a second heat insulating material at the side portion 11c, which has relatively lower heat insulating properties than the first heat insulating material 1c. A heat insulating material 1d is accommodated. The reason why the heat insulating property of the second heat insulating material 1d on the side part 11c side is relatively smaller than the heat insulating property of the first heat insulating material 1c on the bottom part 11a side is in the stacked state with the lid and the stacked state without the lid. While heat transfer may occur from the bottom 11a of the container body 1 of the other heat-insulated transport container to the lid 2 or the opening 11d, another heat-insulated transport container may be provided on the side 11c side of the container body 1. No heat transfer from the container body 1 occurs.

  As shown in FIG. 9 and the like, the thickness dimension D2 of the heat insulating space of the side portion 11c is smaller than the thickness dimension D1 of the heat insulating space of the bottom portion 11a. Further, the bottom portion 11a having the heat insulating space having the thickness D1 is uniformly filled over the whole so that the first heat insulating material 1c substantially fills the thickness D1. On the other hand, the side part 11c having the thickness dimension D2 smaller than the thickness dimension D1 of the bottom part 11a is provided with the second heat insulating material 1d having the thickness dimension D4 smaller than the thickness dimension D2 by the gap D5. It is housed in a state fitted on the outer peripheral surface side. The thickness D4 of the second heat insulating material 1d is, for example, about ／ of the thickness D2 of the side portion 11c. Further, for example, the gap D5 is about １ ／ of the thickness D2 of the side portion 11c. With such a configuration, the cost can be reduced because the second heat insulating material 1d can be made thinner.

  As shown in FIGS. 7, 8, etc., the first heat insulating material 1 c has a dish-shaped structure that matches the bottom shape of the inner container 1 a, and is fitted from below to the bottom of the inner container 1 a, The bottom of the outer container 1b having the same shape is supported from below. The second heat insulating material 1d has a rectangular cylindrical structure, is fitted to the outer periphery of the side part of the inner container 1a from below, and is lower by the inner step surface of the outer container 1b in the engaging step 11b. Is supported. Therefore, the first heat insulating material 1c and the second heat insulating material 1d can be easily attached.

  As shown in FIG. 9 and the like, the upper opening edge of the inner container 1a is formed to be longer than the upper opening edge of the outer container 1b by a predetermined dimension, and is bent into an inverted U-shape toward the outer container 1b. ing. The upper end side opening edge portion of the inner container 1a is superposed on the outer peripheral surface side of the upper end side opening edge portion of the outer container 1b extending straight upward and is welded and integrated with each other. Thus, a heat insulating space having a predetermined thickness D1 and a heat insulating space having a predetermined thickness D2 having a sealing property (airtightness) are formed between the inner container 1a and the outer container 1b. The outer peripheral surface of an opening 11d located on the upper end side of the container body 1, which is a junction between the upper end side opening edge of the inner container 1a and the upper end side opening edge of the outer container 1b, extends radially outward. A convex portion having a predetermined vertical width and projecting a predetermined size is formed.

As shown in FIGS. 2 to 7 and the like, a handle 3 for carrying is provided on the left and right sides 11c of the container body 1. The handle 3 has a structure in which a ring-shaped metal fitting 3a serving as a handle is vertically rotatably attached to a side portion 11c of the container body 1 via a bracket 3b.
The metal fitting 3a is in a state of hanging under its own weight in a normal state. Locking fittings (not shown) are provided at the left and right end portions and the front and rear end portions of the insulated transport container so that the lid 2 can be locked so as not to come off.

  As shown in FIGS. 3, 4, 6, etc., on the bottom 11 a of the container main body 1 (the bottom of the outer container 1 b), a concave surface portion 13 having a predetermined area depressed upward at the center is formed. The concave portion 13 not only increases the strength of the bottom wall surface of the bottom portion 11a as a rib, but also, for example, as shown in FIGS. , The lid 2 is fitted to the convex surface 23 provided on the upper surface 21d side, and is positioned at the center.

  On the outer periphery of the concave portion 13, a plurality of spherical convex portions 4 serving as legs are provided at predetermined intervals. By providing such a convex portion 4, a predetermined vertical clearance is provided between the bottom 11 a of the container body 1 of another heat-insulated transport container and the upper surface 21 d of the lid 2 located below in the stacked state with the lid. Is formed, and a certain heat insulating property is secured, and at the same time, the bottom 11a of the container body 1 is protected from being damaged.

  As shown in FIGS. 7 to 9 and the like, the lid 2 has an inner lid 2a fitted into the opening 11d of the container main body 1 and closing the opening 11d of the container main body 1, and an upper surface side of the inner lid 2a. An outer lid 2b that covers through a heat insulating space having a predetermined thickness D3, and a third heat insulating material 2c housed in the heat insulating space between the inner lid 2a and the outer lid 2b are provided.

  The inner lid 2a is formed by molding a single metal plate. The inner lid 2a is formed in a downwardly convex shape, and is provided integrally with a fitting portion 21a fitted inside the opening 11d of the container body 1 on the outer peripheral side of the fitting portion 21a. A hang portion 21e (hook portion) having an inverted U-shaped cross section is fitted so as to cover an outer wall portion (edge portion) of the opening 11d of the main body 1. The hang portion 21e is configured to extend a predetermined dimension outward in the horizontal direction from the supported portion 21b of the fitting portion 21a, then extend downward again, and curl the extended end thereof.

  The outer lid 2b is formed by molding a single metal plate into a hat-shaped cross section. The edge of the lower end of the outer peripheral portion 21c (side portion) of the outer lid 2b is joined to and integrated with the upper surface of the hang portion 21e, thereby providing a sealing property (airtightness) between the inner lid 2a and the outer lid 2b. It is designed to form a heat insulating space.

  As shown in FIG. 9 and the like, the thickness dimension D3 of the heat insulating space formed between the inner lid 2a and the outer lid 2b in the lid body 2 is the thickness dimension D1 of the heat insulating space at the bottom 11a of the container body 1, 11c is considerably larger than the thickness D2 of the heat insulating space. For example, the thickness dimension D3 of the heat insulating space of the lid 2 is, for example, about four times the thickness dimension D1 of the heat insulating space of the bottom 11a of the container body 1. Thereby, for example, as shown in FIGS. 10 to 14, even in the case of a stack configuration in which a plurality of heat-insulating transport containers are vertically stacked via the lid body 2, the upper and lower thermal insulation objects are mutually connected. Are not affected by each other.

  As shown in FIGS. 1, 2, 4, 5, and 7 to 21, the upper surface 21 d of the lid 2 (the upper surface of the outer lid 2 b) is located at the center and has a predetermined height. A convex portion 23 having a predetermined area, a first engagement having a C-shape in a top view, which prevents movement of the container main body 1 located on both ends in the longitudinal direction of the outer peripheral portion and located above at the time of stacking in the left and right ends. The convex portion 22a is provided with a second engaging convex portion 22b at both ends in the front-rear direction and for preventing the container body 1 located on the upper side during stacking from moving in the front-rear end directions. These components form the engaging portion 20.

  As shown in FIGS. 10 to 15, the height of the first engagement protrusion 22 a and the second engagement protrusion 22 b from the upper surface 21 d and the shape of the inclined surface on the inner surface side are different from those of the cover body 2. In a stacking configuration with a lid vertically stacked via a bottom, the bottom 11a of the container main body 1 located on the upper side is formed in a height and an inclined surface shape that can be securely and stably fitted. Thereby, the container main body 1 of the upper heat-insulated transport container can be reliably supported.

<Single form>
As shown in FIGS. 1 to 9, when the heat-insulated transport container is used alone, first, the lid 2 is removed, and the opening 11 d of the container body 1 is opened. The object to be transported is stored in the container body 1, and then the lid 2 is fitted into the opening 11d to seal the container body 1. Regardless of the temperature condition such as a hot or cold heat-retaining object, the heat-retaining condition such as food or food can be transported while maintaining the good heat-retaining state without being affected by the ambient temperature. .

<About the stack with lid>
As shown in FIGS. 10 to 15, when used in the form of a stack with a lid, first, for example, an object to be kept warm is accommodated in the container main body 1, and the lid 2 is fitted into the opening 11 d of the container main body 1. Then, the container bodies 1 of other heat-insulated transport containers are stacked via the lid 2. It is possible to stack a plurality of other insulated transport containers in the same procedure.

  In such a case, for example, in a case where a cold heat-insulating container is accommodated in one heat-insulating transport container and a hot heat-insulating object is accommodated in the other heat-insulating transport container, the upper portion of the container is transported via the lid 2 during the transportation. The temperature of the heat-insulated transfer container on the lower side and the temperature of the heat-insulated transfer container on the lower side are mutually transmitted to each other, so that the heat insulation state is not maintained and a problem may occur.

  However, in this heat-insulated transport container, as shown in FIGS. 9 and 13 to 15, the thickness D3 between the inner lid 2a and the outer lid 2b of the lid 2 is set differently from the inner container 1a of the container body 1. The thickness D1 and the thickness D2 between the container 1b are approximately four times larger than the thickness D2, and accordingly, the thickness of the third heat insulating material 2c itself in the heat insulating direction is also approximately the same. For this reason, the heat insulation performance of the lid 2 is greatly improved as compared with the related art, and for example, the heat insulation target of the heat insulation target housed in the container body 1 of another heat-insulated transport container on the upper side stacked via the lid 2 is provided. It is possible to effectively prevent heat from being transmitted to the heat-retaining target housed in the container body 1 of the lower heat-insulated transport container through the bottom portion 11a of the container main body 1 and the lid 2 of the lower heat-insulated transport container.

  Further, as a result of the thickness (longitudinal cross-sectional dimension) of the lid 2 itself increasing, the vertical thickness of the engaging edge (overhang portion) with respect to the upper surface (outer wall upper surface) of the opening 11d of the container body 1 can be effectively secured. . In addition, it is possible to secure a sufficient vertical dimension D6 of the fitting portion 21a that enters the opening 11d of the container body 1 in the lid 2, and the strength, heat insulation properties, and sealing properties of the lid fitting portion are also improved. . In addition, the strength of the entire lid 2 is increased, and the support function and durability for supporting the other heat-insulated transport containers on the upper side are also improved.

  Further, the outer peripheral portion of the inner lid 2a constituting the lower surface side of the lid body 2 is bent into an inverted U shape, and the inner peripheral surface, the upper end surface, and the outer peripheral surface of the outer wall portion of the opening 11d of the container body 1 are formed. Is formed, and the lid 2 is fitted to the container body 1 via the hang 21e. Accordingly, the fitting state of the lid 2 to the container body 1 is stabilized, and the sealing performance is further improved by providing the sealing packing in the concave groove portion, so that a liquid content such as a soup can be accommodated as an object to be kept warm. It becomes.

<About stack without lid>
As shown in FIGS. 15 to 21, in the case of using the stack without a lid, first, for example, an object to be kept warm is stored in the container main body 1, and the container main body 1 is directly attached without attaching the lid 2. The container body 1 of another heat-insulated transport container is stacked on the second container. It is possible to stack a plurality of other insulated transport containers in the same procedure.

  In this case, the outer diameter of the fitting portion 21a of the lid 2 and the outer diameter of the bottom 11a of the container body 1 (the outer diameter at the upper end position of the bent portion on the outer peripheral side) are, for example, line aa in FIG. As shown by, they are formed substantially equally. The entire bottom portion 11a of the container body 1 (the vertical dimension D7 in FIG. 9) enters the opening 11d of the container body 1 of another insulated transport container.

  On the other hand, between the outer peripheral end of the bottom portion 11a of the container body 1 (upper end of the bent portion upward on the outer peripheral side) and the lower end of the side portion 11c, there is a side from the outer peripheral end of the bottom portion 11a (upper end of the upwardly bent portion on the outer peripheral side). An engagement step portion 11b is provided which is gently bent outward in the horizontal direction toward the lower end of the portion 11c. By the engagement step 11b, the lid 11 can be inserted into the opening 11d of the container body 1 in the heat-insulated transport container and inserted into and supported by the bottom 11a of the container body 1 in another heat-insulated transport container without using the lid 2. It is possible. In this way, a plurality of heat-insulated transport containers can be stacked in a stackless form. The lid 2 is attached to the opening 11d of the container body 1 of the uppermost insulated transport container.

  As shown in FIG. 9, FIG. 21, etc., the vertical dimension D7 at which the bottom 11a of another heat-insulated transport container can enter the opening 11d of the container body 1 of the heat-insulated transport container located below is the side portion 11c. It is smaller than the height dimension D9. In addition, the vertical dimension D7 of the bottom 11a entering the opening 11d of the container body 1 of the heat-insulating transport container located below is set to the outer wall portion of the opening 11d of the lid 2 located on the upper end side of the container body 1. Of the fitting portion 21a, excluding the overhang portion, is approximately twice as large as the vertical dimension D6. The vertical dimension D7 of the bottom 11a is set to a dimension (for example, less than about 1/3) that is sufficiently smaller than the volume height D8 of the space for storing foods and the like in the container body 1. Therefore, even when the bottom portions 11a of the container main bodies 1 are directly fitted and stacked as shown in FIGS. 16 to 21, the storage space in which the heat insulating target of the container main body 1 of the insulated transport container located below can be stored. A sufficient amount of heat retention target can be accommodated with almost no restriction on the volume (at least 2/3 of the volume can be used effectively: see the dimension D10 in FIG. 21).

  It should be noted that various types of heat insulating materials such as fiber-based and foamed plastic-based materials can be used for the first heat insulating material 1c, the second heat insulating material 1d, and the third heat insulating material 2c used in the above embodiment. As described above, since the side portion 11c of the container body 1 in which the second heat insulating material 1d is used does not come into contact with another heat insulated transport container, the required degree of the heat insulating level is low. Therefore, the type of the heat insulating material used may be lower in cost than the first heat insulating material 1c and the third heat insulating material 2c.

  By stacking a plurality of adiabatic transport containers by combining the above-described stack configuration with a lid and the stack configuration without a lid according to desired conditions, the container body 1 of each adiabatic transport container can maintain a good heat retaining state. It is possible to store and transport a large amount of the object while keeping the temperature.
