[0016] <Embodiment 1> A first embodiment of the present disclosure will be described with reference to Fig. 1 and the like. In this embodiment, a four-door vertical cooling storage cabinet 10 is exemplified as the storage cabinet. In Fig. 1, the front side of the paper is the front side (outside the storage cabinet) of the cooling storage cabinet 10. In Fig. 2, the upper side is the front side of the front panel 18 (outside the storage cabinet).

[0017] As shown in Fig. 1, the cooling storage cabinet 10 has an overall rectangular parallelepiped shape with its longer sides extending in the vertical direction. The cooling storage cabinet 10 includes a main body 11 which is an insulated box opening at the front, a plurality of doors 16 for opening and closing the opening of the main body 11, and a machine room 12 disposed above the main body 11. In the cooling storage cabinet 10, the internal space (storage room) surrounded by the main body 11 and the doors 16 and the space inside the machine room 12 are referred to as the inside of the cabinet, and the space outside of this is referred to as the outside of the cabinet. The cooling storage cabinet 10 is capable of storing and cooling food and drink in the storage room.

[0018] The main body 11 includes a lower wall 13 that forms the bottom of the storage chamber, two side wall portions 14 that rise upward from both lateral ends (both ends in the left and right direction) of the lower wall portion 13, a rear wall portion (not shown) that rises upward from the rear end portion (end portion in the rear direction) of the lower wall portion 13, and an upper wall portion 15 that is connected to the upper ends of the side wall portions 14 and the rear wall portion and forms the ceiling of the storage chamber. A door 16 is attached rotatably to an opening formed by the front ends of the walls 13, 14, and 15.

[0019] Each of the walls 13, 14, 15 and the door 16 is a plate-like body having a double structure with a plate-like inner wall portion whose surface faces the inside of the storage compartment, and a plate-like outer wall portion arranged on the outside of the inner wall portion and whose surface faces the outside of the storage compartment. A heat insulating material (e.g., expanded urethane foam or melamine foam) is filled between the inner wall portion and the outer wall portion. The door 16 has a door main body portion 16A and a door lower end portion 16B arranged below the door main body portion 16A.

[0020] The machine room 12 includes two side panels 17 arranged on both sides, a front panel 18 arranged on the front side of the two side panels 17, and a back panel (not shown) arranged on the rear side of the two side panels 17. Each panel 17, 18 is a plate-like body. In the internal space surrounded by each panel 17, 18 (the internal space of the machine room 12), a part of a cooling device (compressor, condenser, condenser fan, etc.) that cools the storage room is arranged. The front panel 18 is rotatable so that the internal space of the machine room 12 can be opened and closed from the front side. The front panel 18 includes a front panel main body 18A, a front panel lower end 18B arranged below the front panel main body 18A, and two front panel side end portions 18C arranged on both sides in the left-right direction of the front panel main body 18A.

[0021] The cross-sectional structure of the front panel 18 will be described below with reference to FIG. 2. The inner wall and outer wall of the door 16 are also configured in the same manner. The front panel 18 includes a base material 20, a first layer 21 arranged on the front surface 20A side of the base material 20, a second layer 22 arranged on the front surface 21A side of the first layer 21, the front surface 22A of which is exposed to the outside of the storage compartment (front side), and a back surface layer 23 arranged on the back surface 20B side of the base material 20, the back surface layer 23 of which is exposed to the inside of the storage compartment (rear side). The first layer 21 and the second layer 22 may be called the surface layer arranged on the front surface 20A side of the base material 20. The front surface 20A of the base material 20 is in contact with the back surface 21B of the first layer 21. The front surface 21A of the first layer 21 is in contact with the back surface 22B of the second layer 22. The back surface 20B of the substrate 20 is in contact with the front surface 23B of the back surface layer 23.

[0022] The thickness of the base material 20 is not particularly limited, but may be, for example, several hundred μm or several mm. The thickness of the first layer 21 and the back surface layer 23 is not particularly limited, but may be, for example, several μm each. The thickness of the second layer 22 is not particularly limited, but may be, for example, several μm or several tens of μm. The base material 20 may be thicker than the first layer 21, the second layer 22, or the back surface layer 23 (thickest in the front panel 18). The second layer 22 may be thicker than the first layer 21 or the back surface layer 23. The back surface layer 23 may be thinner than the first layer 21 (thinnest in the front panel 18).

[0023] The substrate 20 is a metal plate. The material of the substrate 20 is not particularly limited as long as it is a metal, but one or more of the group of aluminum, copper, iron, etc. (pure metals), or the group of stainless steel, copper alloys, aluminum alloys, etc. (alloys) can be used. As the stainless steel, any of ferritic stainless steel such as SUS430, austenitic stainless steel such as SUS304, and martensitic stainless steel such as SUS410 can be used. For example, the material of the substrate 20 may be SUS430 or SUS304.

[0024] The first layer 21 includes a first resin component which is a main component, an oil-repellent component which has higher oil repellency than the first resin component, and a water-repellent component which has higher water repellency than the first resin component. The second layer 22 includes a second resin component which is a main component, an oil-repellent component which has higher oil repellency than the second resin component, and a water-repellent component which has higher water repellency than the second resin component. Note that when the first layer 21 (or the second layer 22) includes both an oil-repellent component and a water-repellent component, or when the first layer 21 (or the second layer 22) includes a component having both oil and water repellency, it may be described as including an oil-repellent and water-repellent component.

[0025] The oil repellent component is a component that enhances the oil repellency of the first layer 21 and the second layer 22. "Oil repellency" can be defined as a value obtained by dropping oil on the surface of a certain material and quantifying the wettability of the surface of the material (contact angle of oil with respect to the surface of the material). For example, when the second layer 22 contains only the second resin component, the contact angle of oil with respect to the surface of the second layer 22 is larger than when the second layer 22 contains both the second resin component and the oil repellent component.

[0026] The water-repellent component is a component that enhances the water-repellency of the first layer 21 and the second layer 22. "Water repellency" can be defined as a value obtained by dropping water on the surface of a certain material and quantifying how easily the surface of the material wets the surface (the contact angle of water with respect to the surface of the material). For example, when the second layer 22 contains only the second resin component, the contact angle of water with respect to the surface of the second layer 22 is greater than when the second layer 22 contains both the second resin component and the water-repellent component.

[0027] The material of the first resin component and the material of the second resin component are not particularly limited, and for example, one or more of the group consisting of polyester resin, epoxy resin, polyurethane resin, acrylic resin, etc. may be used. The first resin component and the second resin component may be the same component or different components. The first resin component and the second resin component may be a polyester resin.

[0028] The oil repellent component (first oil repellent component) contained in the first layer 21 and the oil repellent component (second oil repellent component) contained in the second layer 22 are not particularly limited, and may be one or more of the group consisting of fluorine-based compounds, silicon-based compounds, natural waxes, synthetic waxes, etc., for example. The first oil repellent component and the second oil repellent component may be the same component or different components. In addition, the ratio (e.g., mass ratio) of the first oil repellent component to the entire first layer 21 and the ratio (e.g., mass ratio) of the second oil repellent component to the entire second layer 22 may be the same or different. The ratio of the second oil repellent component may be higher than the ratio of the first oil repellent component. In order to increase the oil repellency in each layer 21, 22, the crosslink density of the resin component contained in each layer 21, 22 may be increased. When it is desired to increase the oil repellency of the second layer 22 more than that of the first layer 21, the crosslink density of the second resin component may be higher than that of the first resin component.

[0029] The water-repellent component (first water-repellent component) contained in the first layer 21 and the water-repellent component (second water-repellent component) contained in the second layer 22 are not particularly limited, and may be one or more of a group consisting of, for example, fluorine-based compounds, silicon-based compounds, natural waxes, synthetic waxes, etc. The first water-repellent component and the second water-repellent component may be the same component or different components. Furthermore, the ratio (for example, mass ratio) of the first water-repellent component to the entire first layer 21 and the ratio (for example, mass ratio) of the second water-repellent component to the entire second layer 22 may be the same component or different components. The ratio of the second water-repellent component may be higher than the ratio of the first water-repellent component. Furthermore, the water-repellent component may be the same component as the oil-repellent component (may have oil repellency) or different components. In order to increase the water repellency in each layer 21, 22, the crosslink density of the resin component contained in each layer 21, 22 may be increased. When it is desired to make the second layer 22 more water repellent than the first layer 21, the crosslink density of the second resin component may be higher than the crosslink density of the first resin component.

[0030] The second oil-repellent component may have higher oil repellency than the first oil-repellent component. The second water-repellent component may have higher water repellency than the first water-repellent component. The second resin component may have higher oil repellency or water repellency (or oil repellency and water repellency) than the first resin component. The first layer 21 and the second layer 22 may contain additives in addition to the above components.

[0031] As the fluorine-based compound, one or more selected from the group consisting of perfluoroalkyl group-containing fluorine compounds, PTFE (polytetrafluoroethylene), polyvinylidene fluoride resin, copolymers of fluoroolefins and unsaturated monomers such as vinyl ethers, fluorine-containing acrylic resins, fluorine-containing polyester resins, etc. can be used.

[0032] The silicon-based compound may be one or more of the following: fluorine-containing silicon resin, silicon resin with acrylic bond, silicon resin with epoxy, silicon resin with urethane bond, etc. The fluorine-containing silicon resin may be a perfluoroalkyl group-containing silane compound. The perfluoroalkyl group-containing silane compound may be perfluoroisobutyltriethoxysilane, perfluorooctyltriethoxysilane, etc.

[0033] As the natural wax, one or more types may be used selected from the group consisting of vegetable waxes such as candelilla wax, animal waxes such as beeswax, mineral waxes such as montan wax, etc. As the synthetic wax, one or more types may be used selected from the group consisting of synthetic hydrocarbons such as polyethylene wax, montan wax derivatives, paraffin wax derivatives such as chlorinated paraffin, modified waxes such as microcrystalline wax derivatives, 12-hydroxystearic acid, stearic acid amide, phthalic anhydride imide, etc.

[0034] The material of the back surface layer 23 is not particularly limited, and one or more of the group consisting of polyester resin, epoxy resin, polyurethane resin, acrylic resin, etc. can be used. Among these, epoxy resin can be used. The material of the back surface layer 23 may be the same as or different from the material of the first resin component and the material of the second resin component.

[0035] The method of applying the first layer 21, the second layer 22, and the back layer 23 to the substrate 20 is not particularly limited, and for example, a coating method such as spray coating, roller coating, electrodeposition coating, or dipping coating can be adopted. Alternatively, a method in which each layer is made into a film shape and attached to the substrate 20 may be used. The second layer 22 may be applied to the front surface 21A of the first layer 21 after the first layer 21 is applied to the substrate 20.

[0036] Next, the effects of this embodiment will be described. The storage cabinet 10 of this embodiment includes a metal substrate 20, a first layer 21 arranged on the surface side of the substrate 20 and containing a first resin component, and a second layer 22 arranged on the surface 21A side of the first layer 21, the surface 22A of which is a surface exposed to the outside or inside of the storage cabinet, and the second layer 22 contains a second resin component and an oil-repellent component having higher oil repellency than the second resin component.

[0037] According to such a storage cabinet 10, the second layer 22, the surface 22A of which is the surface exposed to the outside or inside of the storage cabinet, contains an oil-repellent component, so that it is possible to prevent characters written on the surface of the second layer 22 with an oil-based pen from penetrating into the inside of the second layer 22, and to prevent colored seasonings from coming into contact with the surface 22A of the second layer 22 and coloring the surface 22A. In this way, various stains including characters and colored seasonings are less likely to adhere to the storage cabinet 10, and even if stains do adhere to the storage cabinet 10, the stains are easier to erase (easily wiped off), making the storage cabinet 10 easier to clean. In addition, since oil is less likely to penetrate the second layer 22, it is easier to impart lubricity, and the storage cabinet 10 can have improved wear resistance. This makes it possible to prevent the surface of the storage cabinet 10 from being scratched when the storage cabinet 10 is transported or handled by a user, and to maintain its appearance. In addition, even if an adhesive member such as a label or a protective sheet is attached to the surface 22A of the second layer 22, the adhesive member can be easily peeled off. For example, even if a foaming agent filled in the storage container 10 as a heat insulating material leaks and adheres to the surface 22A of the second layer 22, the leaked foaming agent can be easily peeled off, so that the number of storage containers 10 that are discarded without being peeled off can be reduced. In addition, if the resin layer that protects the surface 20A of the metal base material 20 has at least a two-layer structure of the first layer 21 and the second layer 22 and the oil repellency is increased in the second layer 22, an inexpensive material can be used for the first layer 21, thereby reducing costs.

[0038] The second layer 22 contains a water-repellent component that has higher water repellency than the second resin component.

[0039] According to such a storage container 10, the surface 22A of the second layer 22 can be configured to exhibit both oil repellency and water repellency.

[0040] The first layer 21 contains an oil-repellent component that has higher oil repellency than the first resin component.

[0041] Such a storage facility 10 can be configured to further improve the oil repellency function.

[0042] The first layer 21 contains a water-repellent component that has higher water repellency than the first resin component.

[0043] Such a storage facility 10 can be configured to further improve the water repellency function.

[0044] The second layer 22 contains a water-repellent component having higher water repellency than the second resin component, and the first layer 21 contains an oil- and water-repellent component having higher oil and water repellency than the first resin component.

[0045] According to such a storage container 10, the first layer 21 and the second layer 22 can be configured to suitably exhibit both the functions related to oil repellency and water repellency.

[0046] <Embodiment 2> Next, a second embodiment of the present disclosure will be described. In the storage cabinet of this embodiment, in the front panel 18 of the storage cabinet 10 of the first embodiment, the first layer 21 contains a first resin component, and the second layer 22 contains a second resin component and a water-repellent component having higher water repellency than the second resin component. On the other hand, the first layer 21 does not contain the oil-repellent component or the water-repellent component. In addition, the second layer 22 does not contain the oil-repellent component.

[0047] When ultraviolet rays hit the resin layer arranged on the surface side of the base material and moisture adheres to that part, the part wrinkles and looks white, which may reduce the design of the storage. However, according to the storage 10 as described above, the second layer 22, whose surface 22A is the surface exposed to the outside or inside of the storage, contains a water-repellent component, so that even if moisture adheres to the surface 22A of the second layer 22, the water is repelled and the above-mentioned situation can be prevented. In addition, it is possible to prevent characters written with a water-based pen on the surface 22A of the second layer 22 from penetrating into the inside of the second layer 22, and to prevent colored seasonings from coming into contact with the surface 22A of the second layer 22 and coloring the surface 22A. In this way, various stains including characters and colored seasonings are less likely to adhere, and even if stains do adhere, the stains are easy to erase, resulting in an easy-to-clean storage 10. In addition, since moisture is less likely to penetrate the second layer 22, lubrication is easily imparted, and the storage container 10 can have improved wear resistance. This makes it possible to prevent the surface of the storage container 10 from being scratched when the storage container 10 is transported or handled by a user, and to maintain its appearance. In addition, even if an adhesive member such as a label or a protective sheet is attached to the surface 22A of the second layer 22, this adhesive member can be easily peeled off. For example, even if a foaming agent filled in the storage container 10 as a heat insulating material leaks and adheres to the surface 22A of the second layer 22, this leaked foaming agent can be easily peeled off, so that the number of storage containers 10 that are discarded without being peeled off can be reduced. In addition, if the resin layer that protects the surface 20A of the metal base material 20 has at least a two-layer structure of the first layer 21 and the second layer 22, and the water repellency is increased in the second layer 22, an inexpensive material can be used for the first layer 21, thereby reducing costs.

[0048] <Embodiment 3> Next, a third embodiment of the present disclosure will be described. The storage of this embodiment is a plate-like body such as a door or a front panel, and includes a first part and a second part constituting an end part of the plate-like body, and the oil-repellent component (or water-repellent portion) contained in the second layer (or the first layer) arranged on the surface side of the base material in the second part has higher oil-repellency (or water-repellent property) than the oil-repellent component (or water-repellent portion) contained in the second layer (or the first layer) arranged on the surface side of the base material in the first part.

[0049] The first part corresponds to the front panel main body 18A or the door main body 16A as shown in FIG. 1 of the first embodiment. The second part corresponds to the front panel lower end 18B, the front panel side end 18C, or the door lower end 16B. For example, the oil repellent component (end side oil repellent component) contained in the second layer arranged on the surface side of the substrate in the front panel lower end 18B or the front panel side end 18C has high oil repellency compared to the oil repellent component (main body side oil repellent component) contained in the second layer arranged on the surface side of the substrate in the front panel main body 18A. In addition, the water repellent component (end side water repellent component) contained in the second layer arranged on the surface side of the substrate in the door lower end 16B has high water repellency compared to the water repellent component (main body side water repellent component) contained in the second layer arranged on the surface side of the substrate in the door main body 16A.

[0050] With such a configuration, for example, it is possible to locally (partially) increase the oil repellency of the parts that are easily touched by the user and easily soiled (for example, the front panel bottom end 18B and the front panel side end 18C) to effectively exert the function related to the oil repellency, while relatively decreasing the oil repellency in other parts, thereby reducing costs. Also, for example, it is possible to locally (partially) increase the water repellency of the parts that are likely to drip and accumulate (for example, the door bottom end 16B) to effectively exert the function related to the water repellency, while relatively decreasing the water repellency in other parts, thereby reducing costs.

[0051] <Other embodiments> The present disclosure is not limited to the embodiments described above and in the drawings. For example, the following embodiments are also included in the technical scope of the present disclosure. Furthermore, in addition to the embodiments described below, various modifications can be made without departing from the spirit of the present disclosure.

[0052] (1) In addition to the above embodiment, the components contained in the second layer and the first layer can be changed as appropriate. For example, the second layer may contain only an oil-repellent component, and the first layer may contain an oil-repellent component or a water-repellent component, or an oil-repellent component and a water-repellent component. Also, the second layer may contain only a water-repellent component, and the first layer may contain an oil-repellent component or a water-repellent component, or an oil-repellent component and a water-repellent component.

[0053] (2) The second layer may be a material in which a specific structure (such as a fluorine atom or a fluorine-containing alkyl group) serving as an oil-repellent component or a water-repellent component is bonded to a resin serving as the second resin component.

[0054] (3) In addition to the above embodiment, the number of layers applied to the substrate can be changed as appropriate. For example, a third layer or more layers may be disposed between the substrate and the first layer, or between the first layer and the second layer. In addition, the substrate may not have a back surface layer on the back surface, and may have two or more back surface layers.

[0055] (4) The portions to which the configurations of the base material, the first layer, and the second layer are applied are not limited to the inner wall portion and the outer wall portion of the front panel and the door. The portions to which such configurations are applied may be, for example, the side panel and the back panel constituting the machine room, or the lower wall portion, the side wall portion, the rear wall portion, the upper wall portion, etc. constituting the main body portion of the storage cabinet. When this technology is applied to the inner wall portion of the door or each wall portion, the inside of the cabinet is the surface side of the base material and each layer. When this technology is applied to the outer wall portion of the door or each wall portion, the outside of the cabinet is the surface side of the base material and each layer.

[0056] (5) The overall configuration of the storage facility can be changed as appropriate. The storage facility may be a two-door or six-door type, or may be horizontal. In addition, the storage facility may be a freezer storage facility or a storage facility having both refrigeration and freezing functions. [Explanation of symbols]
