Abstract
Description
vacuum insulation
[0001] The present invention relates to a vacuum insulation material.
[0002] Vacuum insulation is made by wrapping a porous core with several layers of thin film, using glass fiber (glass wool) as the main raw material, and reducing internal pressure through special treatments such as vacuuming and sealing treatment.
[0003] Because the thermal conductivity of gas is close to zero, vacuum insulation has very high thermal insulation performance compared to general insulation.
[0004] The vacuum insulation material may include an outer layer, a core, and a getter. The outer layer may include a gas barrier film (aluminum foil) that maintains a vacuum state inside the vacuum insulation material. The core may include a porous material (fumed silica, glass wool, urethane foam, etc.) to create an internal vacuum space within the vacuum insulation material and maintain the shape of the vacuum insulation material. The getter may include a material that adsorbs gases and moisture that may occur inside the vacuum insulation material.
[0005] The manufacturing process for vacuum insulation is complex, resulting in high manufacturing costs. Additionally, due to the nature of the manufacturing process, it is difficult to produce vacuum insulation in complex shapes, and it is generally manufactured in specific sizes and shapes. Vacuum insulation is typically produced in the form of panels; however, if the size of the panel increases, the vacuum chamber must also be enlarged, which increases the manufacturing cost.
[0006] In the case of panel-type vacuum insulation, it is sensitive to external impact or damage, and if the internal vacuum (or reduced pressure) is released due to damage, the insulation performance may decrease.
[0007] The background technology described above is possessed or acquired by the inventor in the process of deriving the content of the disclosure of the present application, and cannot necessarily be considered as prior art disclosed to the general public prior to the filing of this application.
[0008] When using conventional vacuum insulation panels (VIPs), it is difficult to manufacture the panels in a free shape. Due to the core material of the vacuum insulation panel, the panel is formed into a plate shape, and the shape of a container is formed using this plate-shaped vacuum insulation panel.
[0009] For example, when intending to form a box-shaped insulation using vacuum insulation panels, U-shaped vacuum insulation panels are stacked to form a box-shaped container with one side open. In this case, the weight of the container increases, and the manufacturing cost rises.
[0010] According to various embodiments, a vacuum insulation material that can have various shapes and is lightweight can be provided.
[0011] According to various embodiments, a vacuum insulation material that is easy to store and capable of changing its shape can be provided.
[0012] According to various embodiments, a vacuum insulation material including a flow path formed between the inside and the outside can be provided to prevent an increase in internal pressure.
[0013] According to various embodiments, by using folding lines with different maximum folding angles, a vacuum insulation material that is easy to deform and easy to store can be provided.

[0062] Hereinafter, embodiments are described in detail with reference to the attached drawings. However, various modifications may be made to the embodiments, and thus the scope of the patent application is not limited or restricted by these embodiments. It should be understood that all modifications, equivalents, and substitutions to the embodiments are included within the scope of the rights.
[0063] The terms used in the embodiments are for illustrative purposes only and should not be interpreted as intended to be limiting. Singular expressions include plural expressions unless the context clearly indicates otherwise. In this specification, terms such as "comprising" or "having" are intended to indicate the existence of the features, numbers, steps, actions, components, parts, or combinations thereof described in the specification, and should be understood as not precluding the existence or addition of one or more other features, numbers, steps, actions, components, parts, or combinations thereof.
[0064] Unless otherwise defined, all terms used herein, including technical or scientific terms, have the same meaning as generally understood by those skilled in the art to which the embodiments pertain. Terms such as those defined in commonly used dictionaries should be interpreted as having a meaning consistent with their meaning in the context of the relevant technology, and should not be interpreted in an ideal or overly formal sense unless explicitly defined in this application.
[0065] In addition, when describing with reference to the attached drawings, identical components are assigned the same reference numeral regardless of drawing symbols, and redundant descriptions thereof are omitted. In describing the embodiments, if it is determined that a detailed description of related prior art could unnecessarily obscure the essence of the embodiments, such detailed description is omitted.
[0066] FIG. 1 is a drawing showing a first type of container (100) according to one embodiment of the present invention. FIG. 2 is a drawing showing a second type of container (100) according to one embodiment of the present invention.
[0067] FIG. 1 is an example showing a container (100) containing paper material. The container (100) of FIG. 1 may be deformed into a first shape or a second shape along a fold line. FIG. 1 is an example showing a container (100) in a first shape that is unfolded along a fold line.
[0068] As shown in FIG. 1, the first type of container (100) may include an opening formed on the upper side. The container (100) may include a receiving space inside.
[0069] When the first type of container (100) shown in FIG. 1 is folded along the fold line, the shape of the container (100) can be deformed into a second type as shown in FIG. 2. When the container (100) is deformed into a second type, it can have a surface shape.
[0070] Although the container (100) illustrated in FIGS. 1 and 2 is described as an example including a paper material, the material of the container (100) is not limited to the example described above. For example, the container (100) may include a material that can be deformed and maintain the shape of the container (100) in each shape (e.g., first shape, second shape).
[0071] The container (100) illustrated in FIGS. 1 and 2 illustrates an example in which it is deformed along a folding line, but is not limited thereto. For example, as shown in FIG. 5 described below, it may include not only a container (100) in which a fluid is injected and its shape is deformed, but also a container (100) in which its shape can be deformed according to various known methods.
[0072] FIG. 3 is a drawing showing a reinforcing material according to one embodiment of the present invention.
[0073] For example, the reinforcing members (131, 133) can support a first form of the container (100). For example, the reinforcing members (131, 133) shown in FIG. 3 represent an example attached to a second form of the container (100). The reinforcing members (131, 133) can support the form and / or shape of the container (100) when the container (100) is deformed into a first form.
[0074] In FIG. 3, the reinforcing members (131, 133) are shown attached horizontally and vertically to the center of the flat container (100), but are not limited thereto. For example, the reinforcing members may be attached to the corners of the flat container (100) or attached to the inside. Additionally, the reinforcing members may be inserted into the interior of the container (100).
[0075] FIG. 4 is a drawing showing a reinforcing material (140) according to one embodiment of the present invention.
[0076] Referring to FIG. 4, the reinforcing material (140) according to one embodiment is formed of an insulating material and can support the first shape of the container (100) by injecting fluid into it.
[0077] For example, the insulating material may include, but is not limited to, EPS (Expanded Polystyrene), EPP (Expanded Polypropylene), PIR (Polyisocyanurate), LCP (liquid crystal polymer), nanocomposite plastics, etc.
[0078] For example, the reinforcing material (140) may include an inlet for injecting fluid into the interior. When the container (100) is deformed into a first shape, fluid may be injected into the reinforcing material (140) through the inlet. For example, the fluid may include air, water, a refrigerant (e.g., PCM (phase change material)), etc.
[0079] In the example as shown in FIG. 4, the reinforcing material (140) may have a shape that wraps around the outside of the container (100). The reinforcing material (140) may support the first shape of the container (100) according to the pressure of the injected fluid.
[0080] FIG. 5 is a drawing showing a container (100) according to one embodiment of the present invention.
[0081] As shown in FIG. 5, the container (150) may include an insulating material. The container (150) may be transformed into a first form by injecting a fluid into the interior in a second form. The description of the insulating material and fluid regarding the container (150) may be substantially the same as the description of the insulating material and fluid regarding the reinforcing material (140).
[0082] Since the container (150) is formed of an insulating material and contains fluid inside, the thermal insulation performance of the vacuum insulating material can be improved. The first shape of the container (150) can be supported by the pressure of the fluid injected into the container (150).
[0083] FIG. 6 is a drawing showing a container (100) inserted into an outer shell material (200) according to one embodiment of the present invention. FIG. 6 shows a cross-section of the outer shell material (200) into which the container (100) is inserted.
[0084] As shown in FIG. 6, a first type of container (100) can be inserted into the outer shell (200). For example, the container (100) can be inserted through an opening (210) formed on the lower side of the outer shell (200).
[0085] The outer shell (200) may be in a shape into which a container (100) can be inserted, as shown in FIG. 6. The outer shell (200) may include a receiving space in which a container (100) is inserted and an item can be stored.
[0086] For example, the outer shell (200) can have its internal space depressurized while the container (100) is inserted. After the internal space of the outer shell (200) is depressurized, the opening (210) formed on the lower side can be sealed. For example, the opening (210) of the outer shell (200) can be sealed by being fused along the line (A in FIG. 6) of the outer shell (200).
[0087] As shown in FIG. 6, the vacuum insulation can accommodate articles and / or cold materials (e.g., ice, dry ice, PCM, etc.) in the receiving space. With articles and / or cold materials accommodated in the receiving space of the vacuum insulation, the upper opening of the vacuum insulation can be sealed. When the upper opening of the vacuum insulation is sealed, the receiving space of the vacuum insulation can be insulated from the outside. Articles within the receiving space of the vacuum insulation can be kept at a low temperature by the cold material.
[0088] For example, the vacuum insulation can be sealed by joining both sides with a sealing means (e.g., tape, Velcro, etc.). The upper opening of the vacuum insulation can be sealed similarly to FIG. 8.
[0089] The vacuum insulation material may be supported in a first form (or unfolded state) by a container (100) and / or a reinforcing material. The container (100) of the vacuum insulation material may serve as a core material.
[0090] The container (100) can be transformed into a first or second shape, making storage easy. Additionally, since the overall shape of the vacuum insulation material is determined by the shape of the container (100), the vacuum insulation material can be manufactured in various shapes. Since the container (100) containing fluid, the container (100) containing paper material, etc., serve as the core material, the vacuum insulation material is lighter in weight compared to conventional vacuum insulation materials containing core materials such as glass wool.
[0091] The vacuum insulation material can be vacuum-sealed by depressurizing the internal space of the outer shell material (200) through the opening (210) of the outer shell material (200). Since the internal space can be vacuum-pressurized through the opening (210) using a vacuum pump or the like, the vacuum insulation material can be manufactured at a lower cost compared to vacuum insulation material manufactured through a vacuum chamber.
[0092] For example, a method for manufacturing a vacuum insulation material may include the operation of transforming a container (100) of a second form (e.g., a flat form) into a first form, the operation of inserting the container (100) of the first form into an outer shell material (200), and the operation of depressurizing and sealing the internal space of the outer shell material (200).
[0093] The manufacturing method of vacuum insulation can be easier compared to vacuum insulation that uses a conventional vacuum chamber to seal the interior under reduced pressure.
[0094] FIG. 7 is a drawing showing a flow path forming member (300) according to one embodiment of the present invention. FIG. 8 is a drawing showing a sealed state of a vacuum insulation material according to one embodiment of the present invention.
[0095] For example, the vacuum insulation material may include a flow path forming member (300). As shown in FIGS. 7 and 8, the flow path forming member (300) may be formed by extending from the inner surface of the outer
[0096] For example, the flow channel forming member (300) may include a material that blocks heat exchange and allows fluid to flow (e.g., Gore-Tex, membrane, etc.). The flow channel forming member (300) may include pores for fluid to flow between the inside and outside of the outer shell material (200).
[0097] A vacuum insulation material including a flow path forming member (300) may have an upper opening sealed as shown in FIG. 8. For example, the flow path forming member (300) can eliminate the pressure difference between the receiving space of the vacuum insulation material and the outside. The vacuum insulation material may contain a low-temperature material (e.g., dry ice) whose volume changes with temperature in the receiving space. When the solid dry ice sublimates into a gas, the pressure in the receiving space of the vacuum insulation material may rise. When the pressure in the receiving space rises, the fluid within the receiving space of the vacuum insulation material may be discharged to the outside through the flow path forming member (300).
[0098] In FIGS. 1 to 8 above, the first form is described as a container in the shape of a square box with the top open, but the first form is not limited to a square box shape.
[0099] FIG. 9 is a drawing showing the unfolded view of a core material (400) according to various embodiments.
[0100] According to one embodiment, the core material (400) may include a first fold line (410-1, 410-2, 410-3, 410-4, 410-5, 410-6) and a second fold line (420).
[0101] For example, the maximum angle that can be folded along the first folding line (410-1, 410-2, 410-3, 410-4, 410-5, 410-6) may be different from the maximum angle that can be folded along the second folding line (420).
[0102] For example, the maximum angle at which it can be folded along the first fold line (410-1, 410-2, 410-3, 410-4, 410-5, 410-6) may be 90 degrees. For example, the maximum angle at which it can be folded along the second fold line (420) may be 180 degrees.
[0103] The core material (400) may include a plurality of regions separated by a first fold line (410-1, 410-2, 410-3, 410-4, 410-5, 410-6) and a second fold line (420).
[0104] For example, the core material (400) may include a polyurethane-based open-cell form with pores. For example, the core material (400) may include urethane foam or an open-cell foamed polymer. The core material (400) may have higher hardness and / or strength compared to glass wool, etc., which are used as core materials for conventional vacuum insulation.
[0105] Since the core material (400) has high strength and / or hardness in the form of foamed plastic (or foamed polymer, polymer polymer), a separate auxiliary core material (e.g., corrugated cardboard, paper, etc.) may not be required. Also, because the core material (400) has high strength and / or hardness and thermal insulation, the vacuum insulation material can maintain its shape and have high thermal insulation with only the core material (400). Additionally, since the core material (400) has high hardness and / or strength compared to glass wool, etc., the core material (400) can be processed to form a fold line (e.g., first fold line (410-1, 410-2, 410-3, 410-4, 410-5, 410-6), second fold line (420)).
[0106] Since the core material (400) has high hardness and / or strength, it can be easily folded along a folding line to form a box shape. Therefore, the vacuum insulation material containing the core material (400) can be easily deformed. In addition, because the core material (400) has high hardness and / or strength, the vacuum insulation material can be easily stacked in multiple layers and stored easily.
[0107] Conventional core materials (e.g., glass wool, PET, etc.) do not have high strength and are soft, so it is difficult to pre-process the folding lines on the core material. On the other hand, since the core material (400) according to one embodiment of the present invention has high hardness and / or strength, the folding lines (e.g., first folding line, second folding line) can be pre-processed on the core material (400).
[0108] In addition, since the existing core material is a soft material, it cannot be folded 180 degrees, but since the core material (400) has high hardness and / or strength, it can be folded 180 degrees along the second folding line (420).
[0109] Referring to FIG. 9, a core material (400) according to one embodiment may include a first surface (e.g., the left side of the first fold line (410-5) in FIG. 9), a second surface adjacent to the right side of the first surface and separated by the first fold line (410-5), a third surface adjacent to the right side of the second surface and separated by the second fold line (420), and a fourth surface adjacent to the right side of the third surface and separated by the first fold line (410-6).
[0110] The core material (400) may include a fifth surface adjacent to the upper side of the first surface and separated by a first fold line (410-1), a sixth surface adjacent to the lower side of the first surface and separated by a first fold line (410-2), a seventh surface adjacent to the upper side of the third surface and separated by a first fold line (410-3), and an eighth surface adjacent to the lower side of the third surface and separated by a first fold line (410-4).
[0111] FIG. 10 is a drawing showing an outer shell material (430) with a core material (400) inserted inside according to various embodiments. In FIG. 10, the part indicated by the dotted line may show the shape of the core material (400) inserted inside the outer shell material (430).
[0112] As shown in FIG. 10, the core material (400) can be inserted into the outer shell material (430). For example, the core material (400) can be inserted into the outer shell material (430) which is in the shape of a bag and has one side open. After the core material (400) is inserted, the interior of the outer shell material (430) is depressurized and the open side can be sealed.
[0113] For example, the vacuum insulation material may include an adhesive means (440) attached to one side of the outer shell material (430). For example, the vacuum insulation material may have both ends fixed by the adhesive means (440). The vacuum insulation material may be folded along the vertical folding lines of the core material (400) (e.g., the first folding line (410-5, 410-6) and the second folding line (420)). When the vacuum insulation material is folded along the vertical folding lines, the vacuum insulation material may be deformed into a box shape having an open surface on the upper and lower sides. The vacuum insulation material deformed into a box shape may maintain its box shape by having both ends fixed by the adhesive means (440).
[0114] For example, the adhesive means (440) may include double-sided tape, but is not limited thereto.
[0115] Since the core material (400) contains a material containing pores or has an open-cell form, the outer material (430) can adhere to the core material (400) when the inside of the outer material (430) is depressurized. Because the outer material (430) and the core material (400) adhere to each other without a separate adhesive or bonding means, the core material (400) can be easily separated from the outer material (430) when the depressurized state inside the outer material (430) is released. The outer material (430) may include a cut line to release the depressurized state inside the outer material (430). Therefore, in the process of disposing of the vacuum insulation material, the vacuum insulation material according to one embodiment of the present invention facilitates the separation of the outer material (430) and the core material (400). On the other hand, in the case of vacuum insulation, where insulation (or an insulation layer) is attached to a core material to maintain its shape, the disposal process is complex due to the process of removing the attached insulation from the core material.
[0116] For example, the vacuum insulation material may include an auxiliary layer located between the outer layer (430) and the core (400). Since the core (400) contains a material containing pores or is in an open-cell form, the auxiliary layer may adhere to the core (400) when the inside of the outer layer (430) is depressurized. The auxiliary layer may adhere to the core (400) (similar to being adhered) even without a separate adhesive or bonding means. For example, the auxiliary layer may include a material to maintain the shape of the vacuum insulation material. The auxiliary layer may include an insulating material to improve the thermal insulation performance of the vacuum insulation material.
[0117] Solid insulation materials are hard and high-hardness materials, such as polymers like expanded polyurethane, EPS, and EPP. Solid insulation materials can be used as containers themselves. In the case of solid insulation materials, foaming results in a closed internal structure.
[0118] For example, the outer shell material (430) may include an opening on one side. Through the opening of the outer shell material (430), the core material (400) may be inserted into the outer shell material (430). Through the opening, the interior of the outer shell material (430) may be depressurized. When the interior of the outer shell material (430) is depressurized, the opening may be sealed. For example, the opening may be sealed by heat-fusion.
[0119] When a solid insulating material having a closed structure is used as the core material, the interior of the outer material (430) may not be uniformly depressurized because the outer material (430) is adsorbed to the solid insulating material on the open side of the outer material (430) when the interior of the outer material (430) is depressurized.
[0120] On the other hand, since the core material (400) has an open-cell structure, when the interior of the outer material (430) is depressurized, the outer material (430) is not adsorbed to the solid insulation material on the open side of the outer material (430), and the interior of the outer material (430) can be depressurized uniformly.
[0121] Fiber insulation refers to soft, cotton-like materials, such as glass wool, PET wool, and mineral wool. Fiber insulation has low hardness and strength, and is difficult to form into a uniform shape.
[0122] Therefore, when using fibrous insulation as a core material, it is difficult to form fold lines on the surface (e.g., first fold lines (410-1, 410-2, 410-3, 410-4, 410-5, 410-6) and second fold lines (420)). Additionally, when using fibrous insulation as a core material, it is difficult to store vacuum insulation in multiple layers because of the low hardness and strength.
[0123] On the other hand, since the core material (400) includes a foamed polymer (or foamed urethane foam, etc.) having an open-cell structure, a fold line (e.g., a first fold line (410-1, 410-2, 410-3, 410-4, 410-5, 410-6) and a second fold line (420)) can be formed on the surface of the core material (400). In addition, because the hardness and strength of the core material (400) are high, it is easy to store vacuum insulation material in multiple layers.
[0124]
[0125] FIG. 11 is a drawing showing folding lines according to various embodiments (e.g., first folding lines (410-1, 410-2, 410-3, 410-4, 410-5, 410-6) and second folding lines (420)).
[0126] For example, the second fold line (420) may be formed such that the angle at which it can be folded along the second fold line is 180 degrees or less. As shown in FIG. 11, the core material (400) of the vacuum insulation material can be folded along the second fold line (420) into an unfolded state (510), a state folded at 90 degrees (520), and a state folded at 180 degrees (530). For example, an area of the core material (400) adjacent to the second fold line (420) can be folded along the second fold line (420) as shown in FIG. 11 (510, 520, 530). The maximum angle that can be folded along the second fold line (420) may mean the maximum angle that the area of the core material (400) adjacent to the second fold line (420) can form (e.g., 0 degrees in state (510), 90 degrees in state (520), and 180 degrees in state (530).
[0127] For example, the cross-section of the core material (400) at the part where the second fold line (420) is formed may be 3 mm or less. By making the cross-section of the core material (400) at the part where the second fold line (420) is formed thin, the resistance when folding the core material (400) can be reduced.
[0128] For example, the first folding line (410) may be formed such that the angle at which it can be folded along the first folding line is 90 degrees or less. The core material (400) of the vacuum insulation material may be folded into an unfolded state (540) and a 90-degree folded state (550) along the first folding line (410). For example, the area of the core material (400) adjacent to the first folding line (410) may be folded along the first folding line (410) as shown in FIG. 11 (540, 550). The maximum angle at which it can be folded along the first folding line (410) may mean the maximum value of the angle that the area of the core material (400) adjacent to the first folding line (410) can form (e.g., 0 degrees in state (540), 90 degrees in state (550)).
[0129] As shown above, the maximum angle that can be folded along the first fold line (e.g., 90 degrees) may differ from the maximum angle that can be folded along the second fold line (e.g., 180 degrees).
[0130] As shown in FIG. 11, the second fold line (420) according to one embodiment may include a groove formed on one side of the core material (400). The first fold line (410) according to one embodiment may include grooves formed on both sides of the core material (400).
[0131] As shown in FIG. 11, the first fold line (410) and the second fold line (420) may differ in shape, size, and form of the groove formed on the surface of the core material (400).
[0132] The shape, size, and form of the grooves associated with the first fold line (410) and the second fold line (420) shown in FIG. 11 are exemplary and are not limited thereto.
[0133] FIG. 12 is a drawing showing a vacuum insulation material for storage according to various embodiments. In FIG. 12, the parts indicated by dotted lines may represent first fold lines (410-1, 410-2, 410-3, 410-4, 410-5, 410-6) formed in a core material (400) inserted inside an outer shell material (430).
[0134] FIG. 12 is a drawing showing a vacuum insulation material in which both ends of the vacuum insulation material of FIG. 10 are fixed by an adhesive means (440). For example, the diagonal corner of the corner where the second fold line (420) is located may be a position fixed by the adhesive means (440).
[0135] In the unfolded state of FIG. 10 (e.g., second form), when both ends of the vacuum insulation are fixed by adhesive means (440), the vacuum insulation can be transformed into a box shape with the upper and lower sides open (e.g., first form, or storage form).
[0136] For example, in FIG. 11, the core material (400) may be located inside the surfaces (451, 453), and the core material (400) may not be located inside the surfaces (452, 454). The surfaces (452, 454) may be formed by the outer skin material (430). The description regarding the surfaces (451, 452, 453, 454) of the upper opening may be applied substantially the same to the surfaces of the lower opening.
[0137] The upper and lower openings of the vacuum insulation material of FIG. 11 can be sealed. For example, the surfaces (451, 453) can be folded along the first folding line (410-1, 410-3), respectively. The upper opening of the vacuum insulation material can be sealed by sealing the surfaces (451, 453) with a sealing means (e.g., tape, etc.). When the surfaces (451, 453) are folded along the first folding line (410-1, 410-3), the core material (400) is not located inside the surfaces (452, 454) formed only by the outer covering material (430), so the surfaces (451, 453) can be moved in the folding direction.
[0138] For example, a sealing means for sealing an upper or lower opening may include a material (e.g., Gore-Tex, etc.) that blocks heat exchange through the sealing means while allowing fluid to flow. By allowing fluid to flow between the internal space (or receiving space) and the external space of the vacuum insulation through the sealing means, the pressure difference between the internal space and the external space of the vacuum insulation can be eliminated.
[0139] The method for sealing the lower opening of a vacuum insulation material can be substantially applied in the same way as the description for sealing the upper opening.
[0140] FIG. 13 is a top view of a vacuum insulation material for storage according to various embodiments.
[0141] The vacuum insulation material of FIG. 12 is shown in a state where both ends are fixed by adhesive means (440) while folded at 90 degrees along the first fold line (410-5, 410-6) and the second fold line (420). FIG. 13 shows the state of the vacuum insulation material that has been deformed such that the angle folded along the first fold line (410-5, 410-6) is less than 90 degrees and the angle folded along the second fold line (420) exceeds 90 degrees.
[0142] As shown in FIG. 13, when the folding angle is changed along the first folding line (410-5, 410-6) and the second folding line (420), the vacuum insulation material can be transformed from the rectangular column shape of FIG. 12 into a rhombus-shaped column. In FIG. 13, when the folding angle along the first folding line (410-5, 410-6) is 0 degrees and the folding angle along the second folding line (420) is 180 degrees, the vacuum insulation material can be transformed into a flat shape.
[0143] As shown in FIG. 13, the angle between each of the surfaces (451, 452, 453, 454) can change depending on the angle of folding along the first fold line (410-5, 410-6) and the second fold line (420).
[0144] Since the angle at which it can be folded differs according to the first folding line (410-1, 410-2, 410-3, 410-4, 410-5, 410-6) and the second folding line (420), the user can easily assemble the vacuum insulation. According to the first folding line (410-1, 410-2, 410-3, 410-4, 410-5, 410-6) and the second folding line (420), the vacuum insulation can be deformed into a flat shape. The vacuum insulation deformed into a flat shape can be easily stacked and easy to store.
[0145] FIG. 14 is a drawing showing a vacuum insulation material (600) before sealing according to various embodiments. FIG. 15 is a drawing showing a sealed vacuum insulation material (700) according to various embodiments.
[0146] FIG. 14 is a drawing showing the (upper or lower) opening of a vacuum insulation material of the first form (or the vacuum insulation material form of FIG. 12). As shown in FIG. 14, the surface of the vacuum insulation material adjacent to the opening may include a surface containing a core material (400) and a surface not containing a core material (400).
[0147] As shown in FIG. 14, the shape of the vacuum insulation can be deformed as shown in FIG. 15 by pushing the side that does not contain the core material (400) into the center of the vacuum insulation and folding the side that contains the core material (400) along the first fold line (410-1, 410-3). In FIG. 15, the internal space (or receiving space) of the vacuum insulation can be sealed by fixing and sealing the side that contains the core material (400) using a sealing means.
[0148] In FIGS. 9 to 15 above, the first form is described as a core material in the shape of a square box with the upper and / or lower sides open, but the first form is not limited to a square box shape. For example, the first form of the core material may be a hexagonal column shape with the upper and / or lower sides open, etc.
[0149] FIG. 16 is a drawing showing the unfolded view of a core material (401) according to various embodiments.
[0150] In the description of the core material (401) in FIG. 16, content that overlaps with or is substantially identical to the description of the core material (401) in FIG. 9 to FIG. 15 may be omitted. Therefore, even if the description of the core material (401) in FIG. 16 is omitted, the description of the core material (400) in FIG. 9 to FIG. 15 may be applied.
[0151] For example, the description of the first fold line (410-1, 410-2, 410-3, 410-4, 410-5, 410-6) and the second fold line (420) of the core material (401) can be applied substantially the same as the description of the first fold line (410-1, 410-2, 410-3, 410-4, 410-5, 410-6) and the second fold line (420) of the core material (400) shown in FIG. 9.
[0152] In addition, the description regarding the material, hardness, strength, characteristics, etc. of the core material (401) can be substantially applied to the description regarding the material, hardness, strength, characteristics, etc. of the core material (400) shown in FIGS. 9 to 15.
[0153] Referring to FIG. 16, the core material (400) may include at least one wing portion (441, 443, 445, 447). For example, the wing portion (441, 443, 445, 447) may be triangular in shape. The shape of the wing portion (441, 443, 445, 447) may have a shape other than that of the illustrated example.
[0154] The wing portions (441, 443, 445, 447) may be located between surfaces (e.g., surfaces (451, 453) where the core material (400) is located inside FIG. 11).
[0155] The core material (401) of FIG. 16 can be inserted into the outer material (430). The description of the outer material (430) of FIG. 16 can be substantially applied to the description of the outer material (430) of FIG. 9 to FIG. 15.
[0156] Referring to FIG. 16, a core material (401) according to one embodiment may include a ninth surface (441) adjacent to the upper side of the second surface and separated by a first fold line, a tenth surface (445) adjacent to the lower side of the second surface and separated by a first fold line, an eleventh surface (443) adjacent to the upper side of the fourth surface and separated by a first fold line, and a twelfth surface (447) adjacent to the lower side of the fourth surface and separated by a first fold line.
[0157] FIG. 17 is a drawing showing a wing portion (441) according to various embodiments.
[0158] For example, the wing portion (441) may be formed so as to be spaced apart from adjacent surfaces (451, 453) by a set distance (e.g., A in FIG. 17, 10mm, 15mm, etc.). When the core material (401) is folded along a folding line (e.g., first folding line (410-1, 410-2, 410-3, 410-4, 410-5, 410-6) and second folding line (420)), if the wing portion (441) is not spaced apart from adjacent surfaces (451, 453), it may be difficult to fold the core material (401). If the wing portion (441) is spaced apart from adjacent surfaces (451, 453) by a set distance, the core material can be easily folded along the folding line.
[0159] FIG. 17 illustrates an example regarding a wing portion (441), but this can be substantially applied to other wing portions (443, 445, 447). Substantially identical to the example illustrated in FIG. 17, the wing portions (443, 445, 447) may be formed spaced apart from adjacent surfaces to the left and / or right by a set distance.
[0160] For example, the ninth surface (441) may be formed at a set distance from the fifth and seventh surfaces. The tenth surface (445) may be formed at a set distance from the sixth and eighth surfaces. The eleventh surface (443) may be formed at a set distance from the seventh surface. The twelfth surface (447) may be formed at a set distance from the eighth surface.
[0161] FIG. 18 is a drawing showing an example of a cross-section of a vacuum insulation material assembled including the core material (401) of FIG. 16.
[0162] As shown in FIG. 18, when the core material (401) is folded along a folding line (e.g., a first folding line (410-1, 410-2, 410-3, 410-4, 410-5, 410-6) and a second folding line (420)), the wing portions (441, 443, 445, 447) can be folded toward the center of the box.
[0163] For example, the wing portions (441, 443, 445, 447) are located on the upper and lower sides of the box-shaped vacuum insulation material, so that the insulation performance inside the vacuum insulation material can be improved. In addition, since the wing portions (441, 443, 445, 447) support the box shape of the vacuum insulation material, when using a core material (401) having wing portions (441, 443, 445, 447), the vacuum insulation material can be easily assembled into a box shape.
[0164]
[0165] FIGS. 19 and 20 are drawings showing cross-sections of a container (500) (or pouch) according to various embodiments.
[0166] For example, a container (505) including a vacuum insulation material (505) may include an outer shell (501) and an inner shell (503) formed such that an internal space is formed and a vacuum insulation material (505) including an opening is positioned on the upper side.
[0167] For example, the outer shell (501) and the outer shell (503) may be formed such that their ends extend from the ends of the vacuum insulation material (505) and include at least a portion of the area (e.g., area (507) of FIG. 20) in which the vacuum insulation material (505) is not located.
[0168] Referring to FIG. 19, a container (500) according to various embodiments may include an outer shell (501), an inner shell (503), and a vacuum insulation material (505). The container (500) may include an internal space for accommodating articles. An opening may be formed on the upper side of the container (500) (or on the upper side of the vacuum insulation material (505)).
[0169] The container (500) shown in FIG. 19 indicates a state where the opening is open. As in FIG. 19, the vacuum insulation material (505) can form a shape with the upper inner side open.
[0170] For example, the vacuum insulation (505) may include at least one surface (505-1) that extends upward from the side of the vacuum insulation (505) and can be folded. The surface (505-1) can be folded along a fold line (505-3).
[0171] The vacuum insulation material (505) can form the shape of a container (500) along a fold line (505-3, 505-3). In FIG. 19 and FIGS. 20 to 23 below, the description of the fold line (505-3, 505-5) of the vacuum insulation material (505) can be substantially the same as the description of the fold line (410) and / or the fold line (420) in FIGS. 9 to 15.
[0172] As shown in FIG. 19, the outer shell (501) and the inner shell (503) may be formed to include a vacuum insulation material (505) inside. The ends of the outer shell (501) and the inner shell (503) may be formed to extend from the end (or surface (505-1)) of the vacuum insulation material (505).
[0173] As shown in FIG. 19, an area where a vacuum insulation material (505) is located and an area where a vacuum insulation material (505) is not located may be formed inside the outer shell (501) and inner shell (503).
[0174]
[0175] FIG. 20 is a drawing showing the opening of a container (500) in a closed state according to one embodiment.
[0176] The area (507) of the outer shell (501) and inner shell (503) where the vacuum insulation material (505) is not located inside can be deformed as shown in FIG. 20. Additionally, as shown in FIG. 20, the surface (505-1) can be folded inward along the fold line (505-3).
[0177] As shown in FIG. 20, when the region (507) is deformed and the surface (505-1) is folded, the upper opening of the container (500) can be sealed.
[0178] For example, when the area (507) is deformed, the surface (505-1) can naturally be folded along the fold line (505-3) as in the example shown in FIG. 20.
[0179] In FIG. 20, an example is illustrated in which the opening of the container (500) is sealed when the angle at which each side (505-1) is folded is 90 degrees or less, but is not limited thereto. For example, similar to the embodiment illustrated in FIG. 12 to FIG. 15, the opening of the container (500) may be sealed when the side (505-1) is folded to 90 degrees.
[0180] FIG. 21 is a drawing showing a vacuum insulation material (505) according to various embodiments.
[0181] For example, the vacuum insulation material (505) may include a lower side, a side extending upward from the lower side, and at least one side (505-1) extending upward from the side and having a first fold line or a second fold line formed therein.
[0182] According to one embodiment, the vacuum insulation material (505) may include at least one surface (505-1). For example, as shown in FIG. 21, the vacuum insulation material (505) may be formed with two surfaces (505-1) extending upward from the side of the vacuum insulation material (505). The two surfaces (505-1) may be formed at positions that are not adjacent to each other.
[0183] As shown in FIG. 21, if two surfaces (505-1) are formed at positions where they are not adjacent to each other, a surface where the core material is not located can be formed between the two surfaces (505-1). When the two surfaces (505-1) are folded along the fold line (505-3), the surface where the core material is not located can move inward.
[0184] With respect to the vacuum insulation material (505) of FIGS. 19 to 23, the description of the vacuum insulation material of FIGS. 9 to 15 can be applied substantially the same way.
[0185] For example, the vacuum insulation material (505) of FIGS. 19 to 23 may include an outer layer, a core, and a fold line. With respect to the outer layer, core, and fold line of the vacuum insulation material (505), the description of the outer layer (430), core (400), and fold line (e.g., first fold line (410, 410-1, 410-2, 410-3, 410-4, 410-5, 410-6), second fold line (420)) of the vacuum insulation material of FIGS. 9 to 15 may be applied substantially the same way.
[0186] FIGS. 22 and FIGS. 23 are drawings showing a container (500) (or pouch) according to various embodiments.
[0187] FIG. 22 shows a container (500-1) with the opening open. FIG. 23 shows a container (500-2) with the opening closed.
[0188] When the area (507) where the vacuum insulation material (505) is not located inside the outer shell (501) and inner shell (503) of the container (500) is deformed as in FIG. 20 and the surface (505-1) of the vacuum insulation material (505) is folded, the opening of the container (500) can be sealed as in FIG. 23.
[0189] As shown in FIG. 23, in order to maintain the region (507) in a deformed state and / or the surface (505-1) in a folded state, the container (500) may include a fixing device (e.g., buckle, adhesive part, magnet, etc.).
[0190] As shown in FIGS. 19 to 23, the area (507) of the outer shell (501) and inner shell (503) where the vacuum insulation material (505) is not located inside is deformed, and the surface (505-1) is folded, so that the opening of the container (500) can be easily sealed.
[0191] In the following description regarding FIGS. 24 to 28, the material of the core material (610) included in the vacuum insulation material (600) may be formed from paper material. While the core material of the vacuum insulation material shown in FIGS. 9 to 18 is a material with high hardness and / or strength, the core material (610) of the vacuum insulation material (600) shown in FIGS. 24 to 28 may be a material with lower hardness and / or strength compared to the core material of the vacuum insulation material shown in FIGS. 9 to 18, including paper material.
[0192] Even if the description regarding the core material (610) and outer material (620) of the vacuum insulation material (600) in FIGS. 24 to 28 is omitted, the description regarding the outer material, core material, etc. of the vacuum insulation material described in FIGS. 9 to 18 may be substantially applied to the core material (610) and outer material (620) of the vacuum insulation material (600) in FIGS. 24 to 28 according to the embodiment.
[0193] FIG. 24 is a drawing showing the core material (610) of a vacuum insulation material (600) according to various embodiments.
[0194] The core material (610) illustrated in FIG. 24 may include paper material, etc. For example, the core material (610) may include the material of a paper box or a corrugated cardboard box. The core material (610) may be formed by attaching liner paper to both sides of the corrugated core.
[0195] The material of the core material (610) described above is exemplary, and the material of the core material (610) is not limited to the above examples. For example, the core material (610) may be formed from a solid board made of paper material, a pulp mold, a honeycomb board, etc.
[0196] FIG. 24 shows an unfolded view of the core material (610) of the vacuum insulation material (600), and the description of the core material (401) shown in FIG. 16 can be applied substantially the same way.
[0197] The shape of the core material (610) of the vacuum insulation material (600) shown in FIG. 24 represents one example among various embodiments and is not limited to the shape shown in FIG. 24. For example, the core material (610) may have a shape that can form the shape of a container according to the shape of the core material (400) shown in FIG. 9 or a fold line.
[0198] FIG. 25 is a drawing showing a vacuum insulation material (600) according to various embodiments.
[0199] The vacuum insulation material (600) illustrated in FIG. 25 shows a state in which a core material (610) is inserted into the interior of the outer material (620), and after the interior of the outer material (620) is depressurized, the opening of the outer material (620) is heat-fused (or sealed).
[0200] Referring to FIG. 25, a vacuum insulation material (600) according to one embodiment may include a core material (610) and an outer layer material (620).
[0201] For example, the core material (610) may be formed from paper material. The core material (610) may be inserted into the interior of the outer covering material (620). With the core material (610) inserted, the interior of the outer covering material (620) may be vacuum-sealed.
[0202] For example, the outer layer (620) may include an adhesive means (630) on one side of the outer layer (620). One end of the vacuum insulation material (600) may be fixed to the other end by the adhesive means (630). With one end of the vacuum insulation material (600) fixed to the other end, the core material (610) may be folded along a fold line. When the core material (610) is folded along a fold line, the vacuum insulation material (600) may form the shape of a container (e.g., a box shape).
[0203] An outer layer (620) according to one embodiment may include a plurality of layers. For example, the outer layer (620) may include a first layer that fuses when heat is applied, a second layer that blocks gas and radiant heat, a third layer that includes a porous structure or a foamed structure, and a fourth layer for mechanical protection.
[0204] The outer covering material (620) may include a plurality of layers stacked in the order of a first layer, a second layer, a third layer, and a fourth layer, or a plurality of layers stacked in the order of a first layer, a third layer, a second layer, and a fourth layer. In the following description, for convenience of explanation, the outer covering material (620) is described as including a plurality of layers stacked in the order of a first layer, a second layer, a third layer, and a fourth layer.
[0205] For example, the outer shell material (620) can be folded so that the first layer faces in a flat shape. The folded outer shell material (620) can be heat-fused at the upper end and the lower end.
[0206] When the upper end (e.g., 12 o'clock direction in FIG. 25) and the lower end (e.g., 6 o'clock direction in FIG. 25) of the folded outer shell material (620) are heat-fused, the opposing first layer can be heat-fused. When the upper end and the lower end of the folded outer shell material (620) are heat-fused, an opening can be formed on one side of the outer shell material (620). The core material (610) can be inserted through the formed opening.
[0207] According to one embodiment, the other end (e.g., 9 o'clock direction in FIG. 25), which is opposite to one side (e.g., 3 o'clock direction in FIG. 25) of the outer skin material (620) having an opening formed therein (e.g., 3 o'clock direction in FIG. 25), can be heat-fused.
[0208] For example, the first layer is intended to seal the outer layer (620) by fusing with the facing first layer when heat is applied to the outer layer (620), and may include a polymer bonding layer having thermal adhesiveness or thermal fusion properties.
[0209] For example, the first layer can be formed from materials such as HDPE (High-Density Polyethylene), LDPE (Low-Density Polyethylene), LLDPE (Linear Low-Density Polyethylene), CPP (Cast PP, Cast Polypropylene), co-extrusion film, and polyethylene-based adhesive layer.
[0210] For example, the second layer is intended to block gas and radiant heat and may include a metal foil, a deposited film, or a blocking polymer layer having a gas and radiant heat blocking function.
[0211] For example, the second layer can be formed from materials such as aluminum foil (Al foil), MPET (Metalized Polyethylene Terephthalate), VMCPP (Vacuum Metallized Cast Polypropylene), EVOH (Ethylene Vinyl Alcohol), PVDC (Polyvinylidene Chloride), and nanocellulose.
[0212] For example, the third layer may include a porous structure or a foamed structure. The third layer has low thermal conductivity and can act as an intermediate buffer.
[0213] For example, the third layer may include PE foam (Polyethylene Foam), PU foam (Polyurethane Foam), EVA foam (Ethylene-Vinyl Acetate Foam), XPS (Extruded Polystyrene), air cap, and a core sheet for VIP.
[0214] For example, the fourth layer is intended to prevent impact, damage, etc. applied from the outside of the outer layer (620) and may include a polymer film or laminate material having a mechanical protection function. For example, the fourth layer may be formed from materials such as HDPE, LDPE, LLDPE, OPP, CPP (Cast PP), nylon (PA), paper and coating film, composite laminate, etc.
[0215] FIG. 26 is a drawing showing a cross-section of an outer covering material (620) according to various embodiments.
[0216] As shown in the cross-section of the outer layer (620) in FIG. 26, the outer layer (620) can be heat-fused with one end (e.g., the upper end at the 12 o'clock direction in FIG. 25) and the other end (e.g., the lower end at the 6 o'clock direction in FIG. 25) while the outer layer (620) is folded so that the first layer faces it.
[0217] As shown in FIG. 26, one end and the other end of the outer shell material (620) folded so that the first layer faces each other may be heat-fused to form a bonded surface (621, 623) (or a fusion line).
[0218] FIGS. 27 and 28 are drawings showing the assembled state of a vacuum insulation material (600) according to various embodiments.
[0219] The vacuum insulation material (600) can be deformed into a box shape as shown in FIGS. 27 and 28 by deforming the core material (610) along the fold line. The upper and lower sides of the deformed vacuum insulation material (600) can be sealed by a sealing means.
[0220] Since the outer covering material (620) is located on the outside and inside of the box-shaped vacuum insulation material (600), the insulation performance of the vacuum insulation material (600) can be high. In addition, since the vacuum insulation material (600) can be stored and delivered in a flat shape (e.g., the shape of the vacuum insulation material (600) shown in FIG. 25), the storage and delivery of the vacuum insulation material (600) are easy.
[0221] In addition, the vacuum insulation material (600) can be manufactured by heat-fusing the outer layer material (620), making it easy to manufacture. Since the cost of the core material (610) and / or the outer layer material (620) is low, the vacuum insulation material (600) can be manufactured at a low cost.
[0222] When the vacuum insulation material (600) includes the core material (610) shown in FIGS. 24 and 25, the cross-section of the vacuum insulation material (600) may be the same as the cross-section of the vacuum insulation material shown in FIG. 18. The wing portions of the core material (610) can block heat transfer through the corners of the box-shaped vacuum insulation material (600).
[0223] Additionally, when an item is positioned on the upper side of the wing portion of the core material (610), heat transfer through contact between the vacuum insulation material (600) and the item can be blocked more effectively. For example, when an item is positioned on the upper side of the wing portion of the core material (610), heat exchange must occur between the item and the external space by passing through the surface of the core material (610) and the wing portion, so the insulation performance of the vacuum insulation material (600) can be high.
