Description

  The present invention relates to a cold and heat insulating box capable of attaching / detaching additional functional parts in a housing space.

  In recent years, with the serious global warming, energy conservation has been promoted in various fields such as industrial machinery, vehicles such as automobiles, consumer equipment such as home appliances, buildings such as houses, and logistics. .

  Among them, in the cold and warm box for keeping warm and cool the stored items, the energy used for maintaining the storage space at a constant temperature occupies a large proportion of the total energy consumption. For this reason, in the cold and heat insulating box, the heat consumption is reduced by arranging the heat insulating material in the panel constituting the casing. Moreover, in addition to arrangement | positioning of a heat insulating material, it adjusts so that the temperature distribution in accommodation space may become uniform according to the kind and magnitude | size of an accommodation thing, for example by using a heat storage agent etc. together.

  For example, Patent Document 1 discloses an outer box and a constant temperature holding container covered with the outer box as a pallet-type constant temperature conveyance container, and the constant temperature holding container defines a constant temperature chamber in which an object to be conveyed is accommodated. And has a structure in which a heat insulating layer is arranged inside a panel constituting the casing. Further, the housing has a plurality of concave or pocket-shaped accommodating portions arranged on the entire inner surface of the panel, and the plurality of heat storage agents are selectively detachably accommodated in the accommodating portion. In addition, a structure in which the heat storage agent or the like does not protrude to the constant greenhouse side is adopted. According to Patent Document 1, since the panel constituting the housing has the above-described structure, it is possible to suppress variation in temperature distribution in the constant temperature chamber by attaching the heat storage agent, and to the size of the conveyed object. Accordingly, it is possible to adjust the mounting position and the number of heat storage agents.

Japanese Patent Laid-Open No. 2015-9388

However, in the housing disclosed in Patent Document 1, it is necessary to increase the thickness of the heat insulating layer constituting the panel in order to provide the above-described recessed or pocket-shaped accommodation portion on the inner surface of the panel. For this reason, the plate | board thickness of the whole panel of a housing | casing becomes large, As a result, the subject that the internal volume of a constant temperature chamber becomes small occurs.
In addition, when a transported object that does not require heat insulation or cold insulation is accommodated in a constant temperature greenhouse, it is not necessary to arrange a heat storage agent in the storage unit. However, in the case structure disclosed in Patent Document 1, the arrangement of the heat storage agent is not necessary. Regardless of the presence or absence, the panel thickness is constant and the thickness cannot be adjusted. For this reason, when the temperature adjustment in a fixed greenhouse is unnecessary, there exists a problem that the accommodation volume of a to-be-conveyed object cannot be increased by adjusting the internal volume of a constant greenhouse, and storage efficiency is bad. Furthermore, since the heat insulation layer has a smaller plate thickness at the portion where the housing portion is located, if the heat storage agent is not disposed in the housing portion, the heat insulation performance of the portion where the housing portion is located will be reduced. There is a possibility that a certain heat insulating property cannot be secured in the housing space.

  The present invention has been made in view of the above circumstances, and in the accommodation space, while ensuring a desired internal volume and a certain heat insulating property, an additional function according to the type required for the type of accommodation and accommodation.

The joint portion can be equipped with additional functional components according to the type of the item to be accommodated and the function required for the accommodation space, while ensuring a certain heat insulating property of the accommodation space by the inner volume and the heat insulation panel. . On the other hand, when the additional function component is unnecessary, the accommodation efficiency of the accommodation space can be improved by removing the additional function component and avoiding the reduction of the accommodation space.

  In the said invention, it is preferable that the said heat insulation panel is comprised with the vacuum heat insulating material. Since the vacuum heat insulating material can exhibit high heat insulating performance with a small plate thickness, it is possible to secure a larger internal volume of the accommodation space and to enhance the cold insulation function in the accommodation space. Because.

  In the said invention, the said heat insulation panel may be arrange | positioned so that attachment or detachment is possible on the surface at the side of the said accommodation space of the said housing | casing. This is because the storage efficiency can be improved by removing the heat insulating panel and securing a larger internal volume of the storage space when the stored object is not required to be kept warm.

  The box for cold and heat insulation according to the present invention is equipped with additional functional parts according to the type of the item and the function required for the accommodation while ensuring a desired internal volume and a certain heat insulating property in the accommodation space. In addition, there is an effect that the accommodation efficiency of the accommodation space can be improved when the additional function component is unnecessary.

B. Thermal insulation panel The thermal insulation panel in this invention is arrange | positioned on the surface at the side of the said accommodation space of the said housing | casing.

1. Configuration of thermal insulation panel The thermal insulation panel is composed of a thermal insulation material. The heat insulating material constituting the heat insulating panel may be any material that exhibits desired heat insulating properties, for example, glass-based heat insulating materials such as glass wool, rock wool, cellulose fiber, and insulation board, and natural materials such as wool and carbonized cork. Examples thereof include a material-based heat insulating material, an extruded foamed polystyrene, a beaded polystyrene, a rigid urethane foam, a high-foamed polyethylene, a phenol foam, and other foamed plastic heat-insulating materials, and a vacuum heat-insulating material.
Especially, in this invention, it is preferable that the said heat insulation panel is comprised with the vacuum heat insulating material. Since the vacuum heat insulating material can exhibit high heat insulating performance with a small plate thickness, it is possible to secure a larger internal volume of the accommodation space and to enhance the cold insulation function in the accommodation space. Because.
Hereinafter, the vacuum heat insulating material used for the said heat insulation panel is demonstrated.

(1) Vacuum heat insulating material A vacuum heat insulating material has the exterior material which coat | covers a core material and a core material. In the vacuum heat insulating material, the core material is enclosed by the exterior material, the inside of the exterior material is sealed under reduced pressure, and the inside exhibits a high degree of vacuum.

(A) Core material As a core material, the thing of the material used for the core material of a conventionally well-known vacuum heat insulating material can be used, for example, powders, such as powders, such as a silica, urethane polymers, fibers, such as glass wool Examples thereof include porous bodies such as bodies. The porous body preferably has a porosity of 50% or more, particularly 90% or more. It is because it can be set as a core material with low heat conductivity.

  Further, the core material may contain a getter agent for adsorbing a minute amount of moisture or gas entering from the outside. Examples of the getter agent include general materials used for vacuum heat insulating materials such as silica, alumina, zeolite, activated carbon and the like.

  The thickness of the said core material will not be specifically limited if it is the thickness which can exhibit a desired heat insulation effect, For example, it is preferable to exist in the range of 1 mm-10 mm in the state after pressure reduction.

(B) Exterior material As the exterior material, a laminate having at least a heat welding layer and a gas barrier layer is used. In the vacuum heat insulating material, the two layers constituting the exterior material are laminated in the order described above from the core material side. The exterior material is usually a flexible film or sheet.

(I) Gas barrier layer The gas barrier layer has a function of blocking intrusion of gas such as water, oxygen, and nitrogen from the outside.
As said gas barrier layer, the vapor deposition film etc. in which the vapor deposition layer was formed in the single side | surface of metal foil and a resin film are mentioned.
Examples of the metal material for the metal foil include aluminum, nickel, stainless steel, iron, copper, and titanium.
Examples of the resin used for the resin film in the vapor deposition film include polyvinyl alcohol resin (PVA), polyamide resin (PA), ethylene vinyl alcohol copolymer resin (EVOH), and polyethylene terephthalate resin (PET). Examples of the material constituting the vapor deposition layer include metals, metal oxides, metal nitrides, inorganic compounds such as silicon oxide, and the like.

  The vapor deposition film may have a gas barrier coating film formed on the vapor deposition layer. Examples of the gas barrier coating film include a coating film formed of a barrier composition containing a water-soluble polymer such as PVA and a metal alkoxide and polycondensed by a sol-gel method.

  The gas barrier layer may be a single layer or a multilayer in which layers having the same composition or different compositions are laminated. The thickness of the gas barrier layer is not particularly limited as long as the gas barrier property can be exhibited, and is, for example, about 9 μm to 100 μm.

  The gas barrier layer may be subjected to surface treatment such as corona discharge treatment, flame treatment, plasma treatment, and ozone treatment. This is because the surface treatment can improve the gas barrier performance and the adhesion with other layers.

Examples of the gas barrier properties of the gas barrier layer, the oxygen permeability ^0.5cc · m -2 · ^{day -1} or less, preferably among them ^0.1cc · m -2 · ^{day -1} or less. Further, the water vapor permeability ^0.2cc · m -2 · ^{day -1} or less, and preferably less inter alia ^0.1cc · m -2 · ^{day -1.} By setting the oxygen and water vapor permeability within the above-described ranges, it is possible to make it difficult for moisture, gas, and the like that have entered the inside of the vacuum heat insulating material to enter the core material.
The oxygen permeability is a value measured using an oxygen permeability measuring device (manufactured by Mocon, USA, OXTRAN) under the conditions of a temperature of 23 ° C. and a humidity of 90% RH based on JIS K7126B. is there. Further, the water vapor permeability is a value measured using a water vapor permeability measuring apparatus (manufactured by MOCON, USA, PERMATRAN) under the conditions of a temperature of 40 ° C. and a humidity of 90% RH.

(Ii) Thermal welding layer When the core material is sealed with the exterior material, the thermal welding layer has a function of thermally sealing the periphery of the exterior material.
Examples of the material for the heat welding layer include polyolefin resins such as polyethylene and unstretched polypropylene (CPP), polyvinyl acetate resins, polyvinyl chloride resins, poly (meth) acrylic resins, and urethane resins. .

  Moreover, the said heat welding layer may contain other materials, such as an anti blocking agent, a lubricant, a flame retardant, and an organic filler.

  The melting point of the heat-welded layer is preferably a temperature at which the bonded surface does not peel off under the usage environment, and is, for example, in the range of 80 ° C. to 300 ° C., in particular, 100 ° C. to It is preferably within the range of 250 ° C.

(Iii) Arbitrary layer It is preferable that the said exterior material has a protective layer. This is because by having the protective layer, the heat welding layer and the gas barrier layer can be protected, and the inside of the vacuum heat insulating material can be protected together. The protective layer is usually disposed on the side opposite to the heat-welded layer side with respect to the gas barrier layer and serves as the outermost layer of the vacuum heat insulating material.

  The protective layer preferably has sufficient strength and is excellent in heat resistance, moisture resistance, pinhole resistance, puncture resistance, and the like. Examples of the material for the protective layer include nylon resins, polyester resins such as polyethylene terephthalate and polyethylene naphthalate, polyamide resins, polyolefin resins such as polypropylene, acrylic resins, cellulose resins, and ethylene-vinyl alcohol copolymers. And the like.

  The protective layer may be in the form of a sheet or a film that is uniaxially or biaxially stretched. The protective layer may be a single layer or a laminate in which layers made of the same material or layers made of different materials are laminated.

  The protective layer may be subjected to surface treatment such as corona discharge treatment, flame treatment, plasma treatment, ozone treatment, etc., in order to improve adhesion with other layers.

  The thickness of the protective layer is not particularly limited as long as it can protect the heat-welded layer and the gas barrier layer, and can be, for example, about 5 μm to 80 μm.

  The exterior material may have an arbitrary layer such as an anchor coat layer, a pinhole layer, an interlayer adhesive layer, in addition to the protective layer described above. As the adhesive used for the interlayer adhesive layer, for example, an adhesive for laminating disclosed in JP 2010-284854 A can be used.

(Iv) Others The exterior material may have a plurality of protective layers and gas barrier layers. For example, two or more gas barrier layers may be provided between the heat welding layer and the protective layer, and two or more protective layers may be provided on the gas barrier layer. Further, another protective layer may be provided between the heat welding layer and the gas barrier layer.

  Each layer constituting the exterior material may be laminated via the interlayer adhesive layer described above, or may be laminated by directly adhering adjacent layers.

  The said exterior material may have transparency and does not need to have it, and can be suitably set according to a use. The transparency of the exterior material is not defined by a strict transmittance, and can be appropriately determined according to the application.

  The gas barrier property of the exterior material depends on the gas barrier property of the gas barrier layer.

(C) Others The vacuum heat insulating material may contain a detection agent inside when the exterior material is transparent. This is because the internal vacuum state can be confirmed from the change in the detection agent. As the detection agent, for example, a gas detection agent such as an oxygen detection agent and a moisture detection agent disclosed in JP-A-2015-117801, a temperature detection agent, and the like can be used. The detection agent may be dispersed inside the vacuum heat insulating material, or may be fixedly arranged at a desired position.

  As an internal vacuum degree of a vacuum heat insulating material, what is necessary is just to exhibit desired heat insulation, for example, it is preferable that it is 5 Pa or less. It is because the convection of the air inside a vacuum heat insulating material can be interrupted | blocked and heat insulation performance can be improved.

The heat conductivity (initial heat conductivity) of the vacuum heat insulating material is, for example, 15 mW · m ⁻¹ · K ⁻¹ or less, particularly 10 mW · m ⁻¹ · K ⁻¹ or less, particularly 5 mW · m ^{−1 in a} 25 ° C. environment. ^-It is preferable that it is below K- ¹ . This is because the vacuum heat insulating material is difficult to conduct heat to the outside, and a high heat insulating effect can be achieved. The thermal conductivity is a value measured by a heat flow meter method using a thermal conductivity measuring device auto lambda (HC-074 manufactured by Eihiro Seiki Co., Ltd.) according to JIS A1412-3.

(2) Others The thickness of the heat insulating panel is not particularly limited as long as it can have a desired heat insulating property, and is appropriately selected according to the use and size of the cold and warm box, the internal volume of the housing space, the heat insulating material to be used, and the like. Can be set.
In addition, the size of the heat insulation panel is not particularly limited as long as it can have a desired heat insulation property, such as the use of a cold and warm box, the wall surface size of the wall plate constituting the housing, the internal volume of the accommodation space, etc. It can be set accordingly.
The plane (plate surface) shape of the heat insulation panel is only required to cover the surface of the housing on the housing space side, and can be appropriately selected according to the wall surface shape of the wall plate constituting the housing.

  When the said heat insulation panel is comprised with the said vacuum heat insulating material, the said heat insulating panel may have a protective material on the surface at the side of accommodation space at least. Vacuum insulation is prone to cracks, wrinkles, and penetration due to external damage, etc., and is easily damaged when used alone.Once the exterior insulation of the vacuum insulation is destroyed, the desired insulation can be maintained due to a decrease in the degree of internal vacuum. It becomes difficult. Therefore, by covering the surface of the vacuum heat insulating material on the accommodation space side with a protective material, the vacuum heat insulating material can be prevented from being damaged and the heat insulating property of the heat insulating panel can be maintained.

  When the said heat insulation panel has a protective material, the said joint part is arrange | positioned on the surface by the side of the said accommodation space of the said heat insulation panel through the said protective material.

  The protective material is preferably one having rigidity capable of protecting the vacuum heat insulating material from external impact, and examples thereof include plywood, steel plate, foam material, resin plate, embossed resin sheet, paperboard and the like. In the case of using the cold and heat insulating box of the present invention in a physical distribution process, a resin plate is preferable as the protective material from the viewpoint of reducing the transportation cost by reducing the weight and volume in the physical distribution. The resin plate is not particularly limited as long as it is formed from a resin. Specific examples of the protective material include a curing material, plastic cardboard, or a composite material thereof. The thickness of the protective material can be set as appropriate.

  The protective material is preferably disposed at least on the accommodation space side surface of the heat insulation panel, and is preferably disposed on the accommodation space side surface and the housing side surface of the heat insulation panel. This is because disposing the protective material on both surfaces of the heat insulating panel can sufficiently prevent the vacuum heat insulating material that is the heat insulating panel from being damaged. In particular, as will be described later, when the heat insulation panel is detachably disposed on the housing space side surface of the housing, a protective material is also disposed on the housing side surface of the heat insulation panel, so The insulation panel can be prevented from being damaged.

  The protective material may be disposed on the heat insulating panel using an adhesive, a pressure sensitive adhesive, a double-sided tape, etc., and an adhesive filler is filled between the protective material and the heat insulating panel, and the filler You may arrange | position on a heat insulation panel via. Examples of the adhesive filler include urethane foam adhesive and rigid urethane foam.

2.

For example, it is 100 mW / (m · K) or less, especially 50 mW / (m · K) or less, particularly preferably 25 mmW / (m · K) or less.
The heat conductivity of a heat insulation panel can be measured with the same measuring method as the heat conductivity of the above-mentioned vacuum heat insulating material.

  In addition, the specific heat of the heat insulating panel is not particularly limited as long as it can exhibit a desired heat insulating property, and depends on the heat insulating material used, for example, 0.5 kJ / (g · K) to 2.0 kJ / (g · K), in particular, within the range of 0.8 kJ / (g · K) to 1.5 kJ / (g · K), particularly 1.0 kJ / (g · K) to 1.4 kJ / (g · K). ) Is preferable.

C. Housing The housing according to the present invention forms an accommodation space by a top plate, a bottom plate, and a side plate.

The material of the wall plate of the housing is not particularly limited as long as the housing space can be formed and the heat insulating panel can be arranged, and examples thereof include metal, wood, and resin. When using the cold and heat insulating box of the present invention in a physical distribution process, it is preferable that the wall plate is formed of a resin from the viewpoint of reducing the transportation cost by reducing the weight and volume in the physical distribution.
All the wall plates may be made of the same material, or at least one of the top plate, the bottom plate, and the side plate may be made of different materials.

  The thickness of the wall plate may be any thickness as long as it has sufficient strength to function as a housing, and can be appropriately set depending on the application.

The casing may have any shape that can form a storage space having a desired internal volume required for the cold and warm box of the present invention. The shape of the housing space formed by the housing can be appropriately designed according to the number of side plates, and examples thereof include three-dimensional shapes such as a cylinder, a triangular prism, a quadrangular prism such as a cube or a rectangular parallelepiped, and other prisms. Of these, a rectangular parallelepiped is preferable. This is because it has a highly versatile shape as a cold and warm box.
About the shape of a top | upper surface board and a bottom face board, it can set suitably according to the shape of accommodation space. Moreover, as a shape of a side plate, quadrangle | tetragon, such as a square and a rectangle, is mentioned, for example.
The number of side plates in the housing is appropriately set according to the shape of the accommodation space, but is at least one (when the shape of the accommodation space is a cylinder) or more. When there are a plurality of side plates, the plurality of side plates may all have the same shape or different shapes depending on the shape of the housing space.

The housing may be capable of being assembled and disassembled. When using the cool and warm box for the present invention in a physical distribution process, the housing is assembled and used when storing the contents, and when not storing the contents, the case is disassembled to disassemble the cool and warm box. This is because the arrangement and storage space can be adjusted. Moreover, it is because it is easy to carry the cool and warm box when the stored item is not stored.
The structure of the housing that can be assembled and disassembled includes, for example, a structure in which the top plate, the bottom plate, and the side plate are all removed, and a plurality of side plates are connected to each other with a folding mechanism. A structure in which the bottom plate is detached from the plurality of side plates, the top plate can be removed from the plurality of side plates, or the top plate is rotatably connected to the one side plate, Examples of the structure include a structure in which the side plate and the bottom plate are rotatably connected and can be folded so that the flat plate surfaces of the plurality of side plates overlap the flat plate surface of the bottom plate.

  When the housing has a structure that can be assembled and disassembled, a groove portion into which the side plate is fitted may be formed on the surface of the bottom plate or the top plate on the accommodation space side. This is because the side plate can be erected by fitting the side plate in the groove portion of the bottom plate.
