By disposing an auxiliary heat insulator in addition to the main heat insulator in the first heat insulator arrangement region, the heat insulating performance of the main body 100 may be further increased. The first auxiliary heat insulating material arrangement area is not limited to a specific location within the first heat insulation material arrangement area, and may be defined at any location determined to be appropriate in order to increase the heat insulation effect. That is, only the main heat insulator (vacuum insulator 200) may be disposed in the first insulator arrangement area, and differently, the main heat insulator (vacuum insulator 200) and auxiliary heat insulator may be disposed in the first heat insulator arrangement area. In this case, the arrangement of the main insulating material and the auxiliary insulating material in the first insulating material arrangement area may vary according to specific implementation purposes. The auxiliary heat insulating material may be formed of the same or similar vacuum insulating material as the main heat insulating material, but the scope of the present invention is not limited thereto, and may be formed of any type of heat insulating material.

On the other hand, the lid 300 may also include a vacuum insulating material 202 therein. Specifically, the lid 300 may also include an outer lid 310 and an inner lid 320 . The outer lid 310 and the inner lid 320 may be manufactured in a shape similar to each other so that they can be coupled to each other by overlapping. In particular, the outer lid 310 and the inner lid 320 may be bonded to each other through the edge portion of the lid 300 . For this purpose, a third bonding region is formed at a position corresponding to the edge portion of the outer lid 310 . and a fourth bonding region may be formed at a position corresponding to the edge of the inner lid 320 . After the third bonding region and the fourth bonding region are brought into contact with each other, a fusion process is performed thereon, whereby the outer lid 310 and the inner lid 320 may be bonded. The third junction region may be a region indicated by C3 in FIG. 3 , and the fourth junction region may be an region indicated by C4 in FIG. 3 , but the scope of the present invention is not limited thereto, and the outer lid 310 and the inner A detailed position or area of the lid 320 may vary depending on a specific shape or design purpose.

As the outer lid 310 and the inner lid 320 are bonded together in this way, a second insulating material arrangement region may be defined between the outer lid 310 and the inner lid 320, and the vacuum insulating material 202 is 2 can be accommodated in the insulation arrangement area. Accordingly, the bonding structure of the outer lid 310 and the inner lid 320 may block and protect the vacuum insulation material 202 disposed in the second insulation material arrangement area from the outside. The vacuum insulating material 202 disposed in the second insulating material arrangement area may have a plate-shaped structure. The second heat insulator arrangement area may be an area indicated by S2 in FIG. 3 .

In some embodiments of the present invention, the vacuum insulation material 202 disposed in the second insulation material arrangement area is a single insulation material having a plate-like structure to fit on one surface defined by the outer lid 310 and the inner lid 320 . can be formed. For example, the vacuum insulating material 202 is formed to be similar to the shape of the upper surface of the lid 300 , for example, to be formed in a rectangular shape to cover most of the area of the lid 300 , to further enhance the insulation effect. can The vacuum insulating material 202 is disposed between the outer lid 310 and the inner lid 320, and is not shown in FIG. 2, but between the outer lid 310 and the inner lid 320 from FIG. 3 or 5. The second insulating material arrangement region S2 is defined so that the shape of the lid 300 and the upper surface thereof is similar, and the plate-shaped vacuum insulating material 202 is arranged in the corresponding region is obvious to those skilled in the art to which the present invention pertains. . Of course, the vacuum insulating material 202 may be manufactured in various other shapes, and the scope of the present invention is not limited to a specific shape.

In some embodiments of the present invention, the lid 300 may include any type of insulation in place of the vacuum insulation 202 .

Meanwhile, the second heat insulator arrangement area may include a second main heat insulator arrangement area for disposing the main heat insulator (vacuum insulator 202 ) and a second auxiliary heat insulator arrangement area for disposing the auxiliary heat insulator. By disposing an auxiliary heat insulator in addition to the main heat insulator in the second heat insulator arrangement region, the heat insulating performance of the lid 300 may be further increased. The second auxiliary heat insulating material arrangement area is not limited to a specific location within the second heat insulation material arrangement area, and may be defined at any location determined to be appropriate in order to increase the heat insulation effect. That is, only the main heat insulator (vacuum insulator 202) may be disposed in the second heat insulator arrangement area, and differently, the main heat insulator (vacuum insulator 202) and auxiliary heat insulator may be disposed in the second heat insulator arrangement area. In this case, the arrangement of the main heat insulating material and the auxiliary heat insulating material in the second heat insulating material arrangement area may vary according to specific implementation purposes. The auxiliary heat insulating material may be formed of the same or similar vacuum insulating material as the main heat insulating material, but the scope of the present invention is not limited thereto, and may be formed of any type of heat insulating material.

As used herein, the term “outer container” may refer to both the outer body 110 or the outer lid 310 , and “inner container” may refer to both the inner body 120 or the inner lid 320 . . In other words, the

outer containers

110 and 310 may include at least one of the outer body 110 and the outer lid 310 , and the

inner containers

120 and 320 include the inner body 120 and the inner lid 320 . may include at least one of

In some embodiments of the present invention, the insulated container 1 may further include a silicone guide 302 between the body 100 and the lid 300 . The silicone guide 302 can make the main body 100 and the lid 300 tightly adhere to each other, thereby further enhancing the thermal insulation effect.

In some embodiments of the present invention, the body 100 and the lid 300 of the insulated container 1 may be made of a plastic material. As the body 100 and the lid 300 are made of a plastic material having low thermal conductivity, an insulating effect resulting from the material itself can be obtained. The plastic material, for example, may be manufactured to include a polyolefin-based polymer material, but the scope of the present invention is not limited thereto, and according to specific implementation purposes, PC (polycarbonate), PBT (Polybutylene Terephthalate), ABS (Acrylonitrile Butadiene) Styrene) or high-performance engineering plastics can also be used. In addition, the plastic material may be manufactured by adopting only a single material, or may be manufactured by mixing two or more materials.

When the vacuum insulators 200 and 202 are used in the heat insulating container 1 , the vacuum insulators 200 and 202 may include a core material, an envelope material, and an adsorbent.

In general, an insulator is a material for reducing heat loss or inflow to the outside, is manufactured to have low thermal conductivity, and can be classified into an insulating material, a thermal insulation material, an insulating material, a fireproof insulation material, and the like. It realizes significantly lower thermal conductivity than general insulators by forming a vacuum by wrapping it with an envelope made of a gas barrier film with low gas permeability. For example, vacuum insulators are widely used in various products requiring insulation, such as refrigerators, vending machines, cold storage cars, building materials, and plumbing equipment.

As the core material, it may be manufactured to include any one or more of materials with low thermal conductivity such as organic fibers, inorganic fibers, powder, and foam insulation, and if it can be disposed inside the outer shell, a core material using any material may be used. there is. In addition, the core material may be manufactured using a single material, may be manufactured using a mixed material, may be manufactured to have a single layer structure, or may be manufactured to have a laminated structure.

The envelope material may be an encapsulant surrounding the core material for vacuum packaging the core material, and may include, for example, a film, a metal barrier layer, and an adhesive layer. The outer shell material is manufactured in the form of a film to prevent gas and moisture permeation to maintain a high vacuum state, protect and seal the core material, and block thermal radiation. Outer material is polyvinylidene chloride (PVDC), polyethylene (PE), polypropylene (PP), polyethylene terephthalate (PET), ethylene-vinyl alcohol copolymer (EVOH), polyvinyl-alcohol (PVOH), graphene oxide ( PVA/GO), polylactic acid (PLA), and nylon (nylon) may be prepared to include one or more, and it is preferable to include aluminum foil or copper foil formed by vapor deposition or sputtering as a metal layer. can do.

The adsorbent disposed together with the core material in the outer shell material serves to adsorb gas and moisture inside the vacuum insulator to uniformly maintain the internal vacuum. As an adsorbent, silica gel, zeolite, activated carbon, zirconium, barium compound, lithium compound, magnesium compound, such as magnesium oxide (MgO), calcium compound, such as calcium oxide (CaO) containing at least one of a material that acts as a moisture absorption It may be formed in the form of a pouch, but the scope of the present invention is not limited thereto.

However, since the envelope of the vacuum insulation material generally uses a thin plate (eg, an aluminum thin plate of 8 um level), when the envelope is damaged, there is a risk that gas and moisture may pass through the damaged part. Accordingly, as described above, the main body 100 and the lid 300 of the insulating container 1 according to an embodiment of the present invention reliably protect the vacuum insulating material disposed therein from damage to ensure the insulating effect. designed for the structure. Even when the heat insulating container 1 uses a heat insulating material other than a vacuum heat insulating material, damage to the heat insulating material reduces the heat insulating effect, and the structure of the heat insulating container 1 can ensure the heat insulating effect even in this case.

In addition, the heat insulating container 1 according to an embodiment of the present invention can obtain the heat insulating effect resulting from the structure of the container itself, apart from the heat insulating effect that can be obtained due to the vacuum insulating material itself, and can be washed and reused It is designed to be easy to use and to be environmentally friendly. For example, in the case of a conventional insulated container using foam insulation, it is vulnerable to damage caused by external pressure or external force, so there is a high possibility that the thermal conductivity increases rapidly even with a small crack, and it is mainly used for disposable use, so it is also related to environmental problems this is high

On the other hand, the insulation container 1 according to an embodiment of the present invention has a poor appearance by using Clean Vibration Technology (CVT) in the process of being manufactured in a structure that can completely block and protect the vacuum insulation material from the outside. It is possible to prevent and secure the durability of the container, as well as to increase the ease of manufacture and productivity.

As described above, the first bonding area may be formed at a position corresponding to the upper corner of the outer body 110 , and the second bonding area may be formed at a position corresponding to the upper corner of the inner body 120 , , After bringing the first bonding region and the second bonding region into contact, a fusion process is performed thereon, so that the outer body 110 and the inner body 120 can be bonded and bonded, and the edge portion of the outer lid 310 is A third bonding area may be formed at a position corresponding to , and a fourth bonding area may be formed at a position corresponding to the edge of the inner lid 320 , and after bringing the third bonding area into contact with the fourth bonding area , by performing a fusion process for this, the outer lid 310 and the inner lid 320 may be bonded to each other.

As a plastic welding technology to be applied to such a welding process, hot plate welding or vibration welding may be considered.

In hot plate fusion, the fusion material fixed to the upper and lower jigs is pressed with a hot plate heated to a temperature slightly higher than the melting temperature of the material, and after heating, softening and melting, the hot plate is removed when the fusion part is sufficiently melted. It is a fusion splicing method that removes, pressurizes, and cools until it hardens. Vibration fusion melts the resin with frictional heat generated from the contact area through the left and right vibrations of the upper jig while pressurizing the thermoplastic resin products. After sufficient melting, continuous pressurization and It is a method of fusion bonding by cooling.

However, in the case of using hot plate fusion, since the fusion proceeds in such a way that the heat conductor directly contacts the product, the fusion surface may be damaged or the bonding strength may be lowered accordingly, and the fusion portion may be melted by conduction heat due to pressurization. Accordingly, it may be difficult to secure the degree of freedom in design because it is necessary to secure the support for the fusion part. In addition, burrs or fluff may occur due to leaking of the melt to the outside after fusion. Even when vibration welding is used, there is a problem that the melt may protrude to the outside of the base material after melting. may not

Accordingly, the outer body 110 and the inner body 120 may be bonded to each other by infrared vibration welding for the first bonding region and the second bonding region, and similarly, the outer lid 310 and the inner lid 320 are connected to the third The bonding region and the fourth bonding region may be bonded to each other by infrared vibration welding.

That is, the manufacturing method of the insulated container 1 includes the steps of forming the outer body 110 in which the first bonding region is defined; forming an inner body 120 in which a second bonding region is defined; disposing an insulating material on the inner surface of the outer body 110; disposing the inner body 120 on the inner surface of the outer body 110; and bonding the outer body 110 and the inner body 120 by performing infrared vibration welding.

Here, the bonding may include heating at least one of the first bonding region and the second bonding region using infrared rays; fixing the outer body 110 and the inner body 120 so that the first bonding area and the second bonding area contact each other; pressing the outer body 110 and the inner body 120 to each other; generating friction and heat by vibrating at least one of the outer body 110 and the inner body 120; and cooling while maintaining pressure.

Similarly, the manufacturing method of the insulated container 1 comprises the steps of forming an outer lid 310 in which a third bonding region is defined; forming an inner lid 320 in which a fourth bonding region is defined; disposing an insulating material on the inner surface of the outer lid 310; placing an inner lid (320) on the inner surface of the outer lid (310); and bonding the outer lid 310 and the inner lid 320 by performing infrared vibration welding.

Here, the bonding may include heating at least one of the third bonding region and the fourth bonding region using infrared rays; fixing the outer lid 310 and the inner lid 320 such that the third bonding region and the fourth bonding region contact each other; pressing the outer lid 310 and the inner lid 320 to each other; vibrating at least one of the outer lid 310 and the inner lid 320 to generate friction and heat; and cooling while maintaining pressure.

Infrared vibration welding is a method of bonding after preheating the bonding surface of the product by irradiating infrared rays generated from an infrared lamp to the bonding surface of the product. It is a method of compressing and bonding the bonding surface of the product, which is melted while preheating and preheated to a constant temperature by infrared rays, using an upper/lower operating table and a vibrating table.

Infrared vibration welding, firstly, can minimize product deformation by solving the problem of melt protrusion that occurs during simple vibration welding, and secondly, in the case of hot plate welding, a direct heating method that relies on conduction By using not only heat conduction and convection, but also the complex heat transfer of radiant heat that passes through space without a medium, it can heat the plastic member faster than hot plate fusion and reduce working time. Third, electricity consumption is relatively small. In addition, in the case of vibration welding, when burrs generated during welding break away from the welding part and flow into the product, it is possible to compensate for the problem of causing poor appearance.

Accordingly, it is possible to prevent a defect in the appearance of the insulated container 1 and secure the durability of the container, as well as increase manufacturing easiness and productivity. That is, in the process of fusing the

outer containers

110 and 310 to the

inner containers

120 and 320, the surfaces of the

outer containers

110 and 310 and the

inner containers

120 and 320 are damaged, or as a result, the outer containers 110, It is possible to prevent the bonding strength between the 310 and the

inner containers

120 and 320 from being lowered. In addition, it is possible to prevent the melt, which may occur during fusion, from coming out of the insulated container 1 to form burrs or lint, thereby preventing deterioration of the appearance of the insulated container 1 . Furthermore, according to embodiments of the present invention, it is possible to increase productivity by shortening the welding operation time during the manufacture of the insulated container 1, and also to secure efficiency by lowering electricity consumption.

In some embodiments of the present invention, the step of disposing the insulating material of the manufacturing method of the insulated container 1 includes the steps of disposing the main insulating material on the inner surface of the

outer container

110 , 310 and the step of the

outer container

In addition, in some embodiments of the present invention, the step of arranging the insulating material of the manufacturing method of the insulating container 1 has a structure folded to fit on five sides defined by the outer body 110 and the inner body 120 . It may include disposing a single insulating material.

Hereinafter, referring to FIGS. 3 to 5 , the structure of the insulating container 1 will be further described.

3 is a view showing a cross-section taken along the line B-B' in FIG. 1 .

Referring to FIG. 3 , as the outer body 110 and the inner body 120 are bonded to each other, a first insulating material arrangement region S1 may be defined between the outer body 110 and the inner body 120 . As described above, the vacuum insulator 200 disposed in the first insulator arrangement region S1 may have a unitary structure folded to fit on five surfaces defined by the outer body 110 and the inner body 120 . . In other words, by folding one vacuum insulator and arranging it to cover all 5 sides, heat loss occurs in the gap between the individually inserted vacuum insulators as in the case of individually inserting a plate-shaped vacuum insulator on each side. This can be prevented, and a higher thermal insulation effect can be expected. As described above, the vacuum insulating material 200 is disposed in the first insulating material arrangement region S1 between the outer body 110 and the inner body 120 , so that the double plastic material structure of the outer body 110 and the inner body 120 .

Specifically, a separation region S3 may be defined between the vacuum insulating material 200 and the outer body 110 . That is, the vacuum insulating material 200 is not seated on the inner surface of the outer body 110, for example, by a structure such as the first insulation support rib (L1), to be disposed spaced apart from the inner surface of the outer body 110 can Here, the first insulating material support rib L1 may be formed on the inner surface of the outer body 110 and may be disposed in the separation region S3 . Accordingly, in the heat insulation effect resulting from the double plastic material structure of the outer body 110 and the inner body 120 and the heat insulation effect due to the vacuum insulation 200 itself, heat is generated by the air layer formed in the spaced region S3. It is possible to obtain an insulating effect in which loss or heat inflow is further prevented.

Similarly, a spaced region S4 may be defined between the vacuum insulating material 200 and the inner body 120 .

Accordingly, the heat insulation effect resulting from the double plastic material structure of the outer body 110 and the inner body 120 and the heat insulation effect due to the vacuum insulator 1 itself, are heated by the air layer formed in the spaced region S4. An insulation effect that additionally prevents loss or heat inflow can be expected.

It is formed between the outer surface of the envelope 220a of the vacuum insulator 200 and the inner surface of the outer body 110 and the outer surface of the envelope 220a of the vacuum insulator 200. It may be formed to have an acute angle. In addition, it goes without saying that the number of the first insulating material support ribs L1 formed in the separation region S3 may be different from that shown in FIG. 4 .

Meanwhile, for example, the second insulating material support rib L2 formed in the separation region S4 may also be formed to be perpendicular to the bottom surface of the inner body 120 extending in the horizontal direction in FIG. 4 . In this case, the second insulating material support rib L2 may be formed on the edge of the inner body 120 or may be formed on the right side of the edge. When the second insulating material supporting rib (L2) is formed on the right side of the corresponding edge, the second insulating material supporting rib (L2) is the inner surface of the inner body 120 facing each other in parallel and the outer surface of the vacuum insulating material 200 (220b) ), it may be formed to be perpendicular to the inner surface of the inner body 120 and the outer surface of the outer surface of the envelope 220b of the vacuum insulator 200 . Here, the inner surface of the inner body 120 refers to a surface facing the envelope 220b of the vacuum insulating material 200 , and the outer surface of the envelope 220b refers to a surface facing the inner surface of the inner body 120 . Similarly, as another example, the second insulating material support rib L2 formed in the separation region S4 may be formed to be perpendicular to a side surface of the inner body 120 extending in the longitudinal direction in FIG. 4 .
