Description

Technical Field

[0001] This invention relates to a takeaway packaging container and its packaging method, and more specifically, to a takeaway packaging container and its packaging method that not only maintains the temperature of the food but also allows it to be cooked by continuously supplying heat to the food from a heating element during delivery. Background Technology

[0002] In recent years, the demand for takeout food has increased rapidly. Generally, takeout food is delivered fully cooked or delivered in a state where it can be cooked and eaten immediately.

[0003] For example, pizzas or fried chicken, although delivered fully cooked, often get cold due to delivery delays caused by high volume or traffic congestion. Furthermore, cooking the food after receipt requires time, which can be inconvenient.

[0004] Therefore, heat-insulated packaging is used to minimize heat loss during delivery. However, even so, the effect is bound to be limited depending on the delivery time and the type of food.

[0005] Therefore, there is a need for a new delivery container and its packaging method, for example, to cook food that needs to be cooked during delivery while maintaining the temperature of already heated food.

[0006] As prior art, Korean Patent No. 10-0617910 (Invention title: Takeout delivery bag equipped with temperature sensor and its heating device) is disclosed. Summary of the Invention

[0035] The advantages and / or features of the present invention, and methods of implementing them, will become apparent from the embodiments described in detail below with reference to the accompanying drawings. However, the invention is not limited to the embodiments disclosed below, but can be embodied in various different forms; these embodiments are merely provided to make the disclosure of the invention more complete and to provide those skilled in the art with the full scope of the invention, which is defined only by the scope of the claims. Throughout the specification, the same reference numerals are used to denote the same constituent elements.

[0036] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0037] Figure 1 This is a diagram illustrating the internal structure of a takeaway packaging container according to an embodiment of the present invention. Figure 2 yes Figure 1 A vertical cross-sectional view of the packaging container. Figure 3 yes Figure 2 The top view of the filter shown.

[0038] As shown in these figures, a takeaway packaging container 100 according to an embodiment of the present invention includes: a heating unit 130 that provides heat to maintain the temperature of food 101 to be delivered or to cook it; an inner container 120 that covers both the food 101 and the heating unit 130; and an outer container 110 that covers the inner container 120.

[0039] According to the structure, by minimizing heat loss of the delivered food 101, it is possible to deliver the food 101 while it is almost still cooking, and it is also possible to cook the food 101 during delivery, thereby providing food that is like cooking at home, thus improving consumer satisfaction.

[0040] The various structures will be described below. The takeaway packaging container 100 of this embodiment has a double packaging structure. The inner container 120 is used to hold the food 101, and the outer container 110 is used to hold the inner container 120. Due to this double structure, the heat from the food 101 in the inner container 120 or the heating element 130 can be prevented from being released to the outside, thereby maintaining the state of the food 101 and ensuring safety.

[0041] First, the outer container 110 of this embodiment may include: a lower container member 111 having an internal space corresponding to the inner container 120 and being a cuboid shape with an open upper part; and an outer cover member 115 for covering the open upper part of the lower container member 111.

[0042] The outer container 110 may be a cardboard box made of thick paper material. However, the shape or material of the outer container 110 is not limited to this.

[0043] The outer container 110 of the structure houses the inner container 120, and a heat-insulating material 170 is arranged between the lower end of the inner container 120 and the bottom of the outer container 110, thereby blocking the heat generated from the inner container 120.

[0044] In this embodiment, the heat insulation material 170 can be set as an egg carton type, which can not only reduce the external impact that may occur during delivery, but also block and absorb the heat generated in the inner container 120, thus minimizing heat loss.

[0045] In addition, the egg-shaped insulation material 170 has an ignition temperature of 400°C, which can reduce the risk of fire during delivery.

[0046] Although this embodiment describes the case where the insulation material 170 is arranged at the bottom of the outer container 110, it is not limited thereto. For example, it can be arranged on the inner wall or top of the outer container 110.

[0047] In addition, such as Figure 1 and Figure 2 As shown, the inner container 120 of this embodiment contains food 101 and a heating part 130 for holding or heating food, and may include: a bottom container member 121, which is formed in the shape of an open cuboid around the lower part and side part of the food 101 and the heating part 130; and a cover member 125, which covers the bottom container member 121.

[0048] The bottom container component 121 and the lid component 125 can be made of thin aluminum. However, they are not limited to this, and other shapes or materials can certainly be used.

[0049] A heating element 130 for heating food 101 is arranged inside the inner space of the container 120, and food 101 is placed on top of it. Furthermore, the heating element 130 is also arranged on top of food 101, thereby providing heat to food 101 and cooking it during delivery. In this embodiment, food 101 can be meat, fish, etc., therefore, when cooked during delivery, the highest quality food 101 can be provided.

[0050] like Figure 1 and Figure 2As shown, the heating unit 130 of this embodiment can be constructed from a heated gravel assembly 130, which is an assembly of heated gravel 131 laid flat as a whole. For this purpose, a wire mesh 135 can be provided to maintain the shape of the heated gravel 131. That is, by placing the heated gravel 131 into a flexible wire mesh 135 and laying it flat in the inner container 120, food 101 can be placed on it.

[0051] Although heated gravel 131 is illustrated as an example of a component for heating food 101 in this embodiment, other heat sources besides gravel 131 may of course be used.

[0052] The gravel 131 of the heated gravel aggregate 130 can be heated to about 100 to 120°C and contained in the inner container 120 together with the food 101. When the above temperature is reached, the food 101 can be delivered while maintaining its temperature.

[0053] Furthermore, the gravel 131 in the heated gravel assembly 130 can be heated to 250 to 350°C, more preferably to 300°C, and then placed in the inner container 120 together with the food 101. When the temperature range is as described above, the food 101 can be cooked during delivery. For example, if raw meat is placed between the heated gravel assemblies 130, the raw meat can be heated during delivery to provide meat that is as freshly grilled as if it were grilled.

[0054] The temperature of the gravel 131 can be adjusted according to the microwave oven's operating time. For example, the heated gravel assembly 130 can be placed in the microwave oven and heated for about 5 minutes to raise the temperature of the gravel 131 to 100 to 120°C.

[0055] Alternatively, the heated aggregate 130 can be placed in a microwave oven and heated for about 10 minutes to raise the temperature of the aggregate 131 to 150 to 180°C.

[0056] To raise the temperature of the heated gravel aggregate 130 to 250 to 300°C, other heating sources, such as a gas furnace, can be used.

[0057] Therefore, the temperature of food 101 can be maintained during delivery, or food 101 can be cooked during delivery to shorten cooking time. Furthermore, after arriving at the destination, the heated gravel aggregate 130 remains at a temperature, so that food 101 can be eaten while placed on top of the heated gravel aggregate.

[0058] As an additional note, when the temperature of the heated grit assembly 130 is set to 300°C for delivery, the temperature of the heated grit assembly 130 can still be maintained at around 100°C even after about 20 to 30 minutes. Moreover, after about 60 minutes, the temperature of the heated grit assembly 130 can still be maintained at around 60°C. Therefore, not only can the food 101 be cooked during delivery, but the temperature of the food 101 can also be maintained after arriving at the destination.

[0059] In other words, when the delivery time is about 20 to 30 minutes, the temperature of the heated gravel aggregate is 300°C, so food 101 can be cooked. Even after the consumer has received food 101, since the temperature can be maintained from 100°C to 60°C for more than 30 minutes, the consumer can enjoy the heat preservation effect while eating food 101.

[0060] Additionally, to prevent foods such as meat 101 from directly contacting the heated gravel aggregate 130, such as Figure 2 and Figure 3 As shown, a filter screen 140 can be arranged between the heated gravel aggregate 130 and the food 101.

[0061] The filter 140 of this embodiment can be made of aluminum foil with a plurality of holes 141 regularly formed thereon, and the holes 141 can have a variety of shapes.

[0062] The filter 140 is used to separate the heated gravel aggregate 130 at about 300°C from the food 101. Thus, during the cooking process of the food 101, the water and oil transmitted through the multiple holes 141 are turned into steam, making the meat of the raw meat and other foods 101 tender and delicious.

[0063] In addition, when raw meat is grilled over direct fire such as charcoal, carcinogens may be produced during the cooking process. However, in this embodiment, food 101, such as hot-grilled meat, provided from the heated grit assembly 130, is used through a filter 140. Therefore, meat with the texture of charcoal-grilled meat or boiled meat can be obtained, while minimizing carcinogens.

[0064] Although not shown, a handle may be provided on one side of the filter 140, so that the filter 140 can be easily removed.

[0065] The following describes a method for packaging food in a takeaway packaging container according to the above embodiment.

[0066] A packaging method for packaging food 101 in a takeaway packaging container 100 according to an embodiment of the present invention may include: firstly, arranging heat-insulating material 170 in an outer container 110; placing a bottom container member 121 of an inner container 120 therein, and arranging a heating part 130 in the bottom container member 121, i.e., the heating part 130 of the heated grit assembly 130 in this embodiment; placing a filter screen 140 on top of the heating part 130, and arranging the food 101 on top of it; placing another filter screen 140 on top of the food 101, and arranging the heating part 130 on top of it, and then covering the bottom container member 121 with a cover member 125, thereby covering the inner container 120; and covering the lower container member 111 of the outer container 110 with an outer cover member.

[0067] Through the above steps, food 101 can be safely packaged into takeaway packaging container 100, and heat is provided to food 101 by heating the grit assembly 130 during delivery, thereby not only maintaining the temperature of food 101, but also cooking food 101.

[0068] However, in the above embodiments, although the case of packaging food 101 after placing inner container 120 into outer container 110 is described, it is not limited to this. For example, it is also possible to first put food 101 into inner container 120 and cover inner container 120 before putting inner container 120 into outer container 110.

[0069] Thus, according to one embodiment of the present invention, during the delivery process, by continuously supplying heat to the food 101 from the heating unit 130, the food 101 can be kept at a temperature and can also be cooked, thereby providing consumers with food 101 that looks like it has just been cooked, thus improving satisfaction.

[0070] Furthermore, since the heating element 130 is arranged not only at the bottom of the food 101 but also at the top of the food 101, the food 101, such as meat, can be grilled while being pressurized appropriately. As a result, the food 101 can be fully cooked within the time it takes for the packaged food to reach its destination, thereby improving consumer satisfaction.

[0071] The following describes a takeaway packaging container according to another embodiment of the present invention, but the description of the parts that actually correspond to the structure of the above embodiment will be omitted.

[0072] Figure 4 This is a diagram illustrating the internal structure of a takeaway packaging container according to another embodiment of the present invention.

[0073] As shown in the figure, in the delivery packaging container 200 of this embodiment, since the food 201 is placed in two layers, a heated grit assembly 230 can be arranged between the food 201. A heated grit assembly 230 is placed on the upper part of the upper food 201 and on the lower part of the lower food 201.

[0074] In addition, a filter screen 240 can be arranged between the heated gravel aggregate 230 and the food 201.

[0075] When packaging more food (201), it can be as follows: Figure 4 The arrangement shown includes a heated grit assembly 230 and a filter screen 240, which allows the food 201 to maintain its temperature or be cooked smoothly during delivery.

[0076] The following will describe a takeaway packaging container according to another embodiment of the present invention, but the description of structures that actually correspond to the structures of the above embodiments will be omitted.

[0077] Figure 5 This is a diagram illustrating the internal structure of a takeaway packaging container according to another embodiment of the present invention.

[0078] As shown in the figure, the takeaway packaging container 300 in this embodiment can be equipped with a heated cleaning stone plate 330 as a heating part 330.

[0079] The cleaning stone plate 330 has regular grooves 331, so even if food 301 is placed on it, it can prevent the food 301 from being burned locally, and ensure that the food 301 is thoroughly cooked.
