Description

Technology Field

[0001] The present invention relates to a cooking container, and more specifically, to a double cooking container having a relatively small container and a relatively large container capable of accommodating it. Background Technology

[0002] Oden (fish cake), enjoyed by people of all ages, is typically cooked at home or purchased from snack shops and street stalls. While home cooking usually takes place in deep, round pots, snack shops and stalls typically prepare fish cakes skewered on bamboo in deep, rectangular pots, and many people prefer to eat the fish cakes sold in this manner. Furthermore, with the recent widespread popularity of camping as a hobby, people also desire to eat skewered fish cakes, just like those sold at snack shops or street stalls, while camping or engaging in other outdoor activities.

[0003] However, fish cakes need to be completely submerged in water to cook properly and evenly. Cooking fish cakes on skewers requires a deep pot, but many ordinary households do not have deep, rectangular cooking utensils. Recently, rectangular oden pots for home use have been sold, but they are all shallow, with a depth of only about 6 to 8 cm. If the pot is shallow, there is a disadvantage in that you either cook without skewers or, if you do, lay the fish cakes flat so they are submerged in water. Also, if you lay the fish cakes almost horizontally after skewering them, the amount of fish cakes that can be cooked at once is significantly reduced.

[0004] To cook fish cakes on skewers in a square oden pot at an angle (e.g., 45 to 60 degrees), as is done at snack shops or street stalls, the depth of the cooking area must be at least 12 cm, and the pot must be filled with broth at least halfway. However, if a square oden pot covering the surface area of ​​a gas or induction stove is made to be at least 12 cm deep, it will have a full capacity of 8 to 10 liters or more. Even if you fill it with water at least halfway to make broth, about 4 to 6 liters of water will be needed. This amount of water requires an enormous amount of ingredients to create the flavor of the broth, making it too much for 2 to 3 people to eat at once. The problem to be solved

[0005] The purpose of this invention is to solve the aforementioned problems by providing a double container that allows fish cakes to be cooked using a relatively small amount of broth. means of solving the problem

[0006] According to one embodiment of the present invention, a first container (10) having a first side (12) and a second side (13) facing each other, and a third side (14) and a fourth side (15) perpendicular thereto and facing each other; and a second container (20) that can be inserted into a first container (10), having a first side and a second side facing each other, and a third side and a fourth side perpendicular thereto facing each other; wherein the first container (10) includes protrusions (12a, 13a) that protrude horizontally for a predetermined length inwardly into the container on the first side and the second side of the first container, respectively, and the second container (20) includes first protrusions (22a, 23a) that protrude horizontally for a predetermined length outwardly into the container on the first side and the second side of the second container, respectively, and when the second container is seated on the bottom surface (11) of the first container, the first protrusions (22a, 23a) of the second container are located at a lower height than the protrusions (12a, 13a) of the first container, and each of the protrusions (12a, 13a) of the first container is of the first protrusions (22a, 23a) of the second container A double cooking container configured to be positioned so as to interfere with each other in a vertical direction is disclosed.

[0007] In one embodiment, the width of the first and second sides of the second container is less than or equal to half the width of the first and second sides of the first container, and the horizontal length of the protrusions (12a, 13a) of the first container may be less than half the width of the first and second sides of the first container.

[0008] In one embodiment, the second container (20) may further include second protrusions (22b, 23b) that protrude horizontally outward for a predetermined length from the container at a height lower than the first protrusions (22a, 23a) of the first side and the second side. Effects of the invention

[0009] When using a double container according to one embodiment of the present invention, the user can appropriately adjust the water in the first container according to their discretion while cooking food or eating food after cooking, thereby cooking food with the second container (20) in close contact with the first container (10) and, after cooking is complete, the second container (20) is separated from the first container (10) by buoyancy so that the cooked food can be heated indirectly, and at the same time, the water in the first container (10) can also be used as a double boiler to heat alcohol or beverages.

Specific details for implementing the invention

[0011] The above objectives, other objectives, features, and advantages of the present invention will be easily understood through the following preferred embodiments associated with the accompanying drawings. However, the present invention is not limited to the embodiments described herein and may be embodied in other forms. Rather, the embodiments introduced herein are provided to ensure that the disclosed content is thorough and complete, and to ensure that the spirit of the present invention is sufficiently conveyed to those skilled in the art.

[0012] In this specification, when a component is mentioned as being on another component, it means that it may be formed directly on the other component or that a third component may be interposed between them. Similarly, when a component is mentioned as being connected (or coupled, fastened, attached, etc.) to another component in this specification, it means that it may be directly connected (or coupled, fastened, attached, etc.) to the other component or indirectly connected (or coupled, fastened, attached, etc.) by interposing a third component between them. Additionally, the thicknesses of the components in the drawings of this specification are exaggerated for the effective explanation of the technical content.

[0013] FIG. 1 is a drawing illustrating a double container for cooking according to one embodiment. Referring to FIG. 1, a double container for cooking according to one embodiment may be composed of a first container (10) with a relatively large volume and a second container (20) with a relatively small volume.

[0014] The first container (10) may be, for example, a container with an open top and a cuboid shape, with a width and length of 20 centimeters to 40 centimeters each and a height of 10 centimeters to 20 centimeters, and these figures are exemplary. The second container (20) may have a shape and volume that can be inserted into the interior of the first container (20) as shown in FIG. 1, and may be, for example, a container with an open top and a cuboid shape, having a volume of 1 / 3 to 1 / 2 of the first container (10).

[0015] The first container (10) and the second container (20) can each be made of a material such as stainless steel and can be heated by placing them on a gas stove or a portable burner. In one embodiment, as shown in FIG. 1, the second container (20) is placed inside the first container (10), and ingredients such as fish cakes and broth are placed in the second container (20). After filling the first container (10) with water to a predetermined height, the first container can be heated to make food. In this case, since the broth is placed only in the second container (20) and not in the first container (10), there is an advantage in being able to cook fish cakes and other dishes without consuming more broth than necessary.

[0016] The specific configuration of the double container described above will be explained below with reference to FIGS. 2 to 6.

[0017] FIG. 2 schematically shows a perspective view of a first container (10) according to one embodiment.

[0018] The first container (10) may be a cuboid-shaped container with an open top. For example, the first container (10) is composed of a rectangular bottom surface (11) and four sides (12, 13, 14, 15) extending upward from each corner of the bottom surface (11). The first side (12) and the second side (13) face each other, and the third side (14) and the fourth side (15) face each other. For convenience of explanation, it is assumed that the bottom surface (11) is rectangular in shape and that the first side (12) and the second side (13) are longer in length (width) than the third side (14) and the fourth side (15).

[0019] In one embodiment, the first container (10) includes protrusions (12a, 13a) that protrude horizontally for a predetermined length into the container on the first side (12) and the second side (13) facing each other. The method of forming the protrusions (12a, 13a) is not limited. For example, after manufacturing the container (10), the protrusions (12a, 13a) can be formed by applying pressure from the outside to the inside at the points where the protrusions are formed on the first side (12) and the second side (13), or alternatively, the protrusions (12a, 13a) can be formed by attaching a rod of a predetermined length horizontally by welding or the like at a predetermined position on the inner surface of the first side (12) and the second side (13). Additionally, protrusions (12a, 13a) may be formed on the inner surface of the first side (12) and the second side (13), or on the upper corners of the first side (12) and the second side (13).

[0020] It is preferable that the length of the protrusions (12a, 13a) be less than half the length (width) of the first side (12) and the second side (13). For example, the length of the protrusions (12a, 13a) may be between 1 / 4 and 1 / 3 of the length (width) of the first side (12) and the second side (13).

[0021] In an alternative embodiment, the first container (10) may further include protrusions (14a, 15a) that protrude horizontally for a predetermined length into the container on each of the third side (14) and the fourth side (15) facing each other. The method of forming the protrusions (14a, 15a) is not limited. Additionally, the length of the protrusions (14a, 15a) may be less than half the length (width) of the third side (14) and the fourth side (15).

[0022] FIG. 3 schematically shows a perspective view of a second container (20) according to one embodiment.

[0023] The second container (20) may be a cuboid-shaped container with an open top. For example, the second container (20) consists of a rectangular bottom surface (21) and four sides extending upward from each corner of the bottom surface (21). The bottom surface (21) may be rectangular or square in shape.

[0024] The length (width) of the first side (22) and the second side (23) facing each other of the second container (20) may be less than or equal to half the width of the first and second sides (12, 13) of the first container (10). More preferably, the length of the first and second sides (22, 23) of the second container (20) is smaller than the remaining length obtained by subtracting the length of the protrusions (12a, 13a) from the length of the first and second sides (12, 13) of the first container (10), respectively, and in this case, the second container (20) can be placed inside the first container (10) without interference from the protrusions (12a, 13a).

[0025] In addition, it will be understood that in order for the second container (20) to be placed in the first container (10), the lengths of the mutually facing third side (24) and fourth side (25) of the second container (20) must be smaller than the lengths of the third side (14) and fourth side (15) of the first container (10).

[0026] In one embodiment, the second container (20) may include a first protrusion (22a, 23a) that protrudes horizontally for a predetermined length outward from the container on each of the first side (22) and the second side (23) facing each other. The method of forming the first protrusion (22a, 23a) is not limited. For example, the protrusion (22a, 23a) may be formed by pressing the side of the second container (20) from the inside outward direction, or alternatively, the protrusion (22a, 23a) may be formed by attaching a rod of a predetermined length horizontally by welding or the like at a predetermined position on the outer surface of the first side and the second side. Additionally, the protrusion (22a, 23a) may be formed on the outer surface of the first side (22) and the second side (23), or on the upper corner of the first side (22) and the second side (23).

[0027] The length of the first protrusion (22a, 23a) of the second container (20) is not particularly limited and, for example, may have a length greater than 1 / 2 of the horizontal length (width) of the first side and the second side of the second container (20).

[0028] As indicated by the dotted line in FIG. 3, in an alternative embodiment, the second container (20) may further include second protrusions (22b, 22c, 23b, 23c) that protrude horizontally for a predetermined length outward from the container on each of the first and second sides facing each other.

[0029] One or more second protrusions are formed on the first and second sides of the second container (20) at a height lower than that of the first protrusions (22a, 23a), respectively, on the outside of the container. For example, a second protrusion (22b, 23b) may be formed at a predetermined height below the first protrusion (22a, 23), and another second protrusion (22c, 23c) may be further formed at a predetermined height below it.

[0030] FIG. 4 schematically shows a perspective view of a second container (30) according to an alternative embodiment.

[0031] According to an alternative embodiment, the second container (30) is a rectangular container with an open top, consisting of a square bottom surface and four sides extending upward from each corner of the bottom surface.

[0032] Compared to the second container (20) of FIG. 3, the second container (30) of FIG. 4 differs in that it is inserted vertically into the first container (10). That is, in the case of the second container (20) of FIG. 3, the first and second sides (22, 23) are approximately half the length of the first and second sides (12, 13) of the first container (10), and the third and fourth sides (24, 25) are slightly shorter than the length of the third and fourth sides (14, 15) of the first container (10), whereas in the case of the second container (30) of FIG. 4, the first and second sides are slightly shorter than the length of the first and second sides (12, 13) of the first container (10), and the third and fourth sides are approximately half the length of the third and fourth sides (14, 15) of the first container (10).

[0033] According to an alternative embodiment of FIG. 4, the second container (30) may include protrusions (34a, 35a) that protrude horizontally outward from the container by a predetermined length on each of the two sides (i.e., the third and fourth sides) of relatively short length. The method of forming the protrusions (34a, 35a) is not limited, and for example, the protrusions (34a, 35a) may be formed by pressing the sides of the second container (30) from the inside outward direction, or by attaching a rod of a predetermined length horizontally at a predetermined position on the outer surface of the container by welding, etc.

[0034] In the case of the second container (30) of FIG. 4, additional protrusions (22b, 22c, 23b, 23c) as indicated by dotted lines in FIG. 3 may also be included, but are omitted in FIG. 4.

[0035] FIG. 5 schematically illustrates a plan view of the first container (10) to explain the method of inserting and seating the second container (20, 30) into the first container (10).

[0036] When placing the second container (20) of FIG. 3 into the first container (10), the second container (20) is inserted into an area without protrusions (12a, 13a) of the first container (10) (i.e., the right area in FIG. 5), as indicated by the dotted line in the drawing, and then the second container (20) is slid (to the left in FIG. 5) as indicated by the arrow, thereby allowing the second container (20) to be placed in the first container (10) as in FIG. 1.

[0037] In addition, it will be understood that if you want to put the second container (30) of FIG. 4 into the first container (10), you can insert the second container (30) into the area where there are no protrusions (14a, 15a) of the first container (10) (i.e., the upper area in FIG. 5) and then slide the second container (30) as indicated by the arrow to place the second container (30) into the first container (10).

[0038] FIG. 6 is a cross-sectional view along line A-A' of FIG. 1, schematically showing the state in which the second container (20) is seated on the first container (10).

[0039] In one embodiment, when the second container (20) is seated on the bottom of the first container (10) (i.e., when the bottom surface (21) of the second container (20) is in close contact with the bottom surface (11) of the first container (10), the first protrusions (22a, 23a) of the second container (20) are located at a lower height than the protrusions (12a, 13a) of the first container. Also, at this time, each of the protrusions (12a, 13a) of the first container (10) is located in a position that interferes in a vertical direction with each of the protrusions (22a, 23a) of the second container (20). That is, since the protrusions (22a, 23a) of the second container (20) interfere with the protrusions (22a, 23a) of the first container (10) and cannot rise, the rise of the second container (20) is restricted.

[0040] And as shown in the enlarged view of FIG. 6, in a preferred embodiment, when the second container (20) is seated on the bottom of the first container (10), it is preferable that the protrusions (12a, 13a) of the first container (10) and the protrusions (22a, 23a) of the second container (20) are not in close contact and that there is a gap (G) between the two protrusions. The gap (G) may be, for example, between 1 millimeter and 1 centimeter, but the numerical value is not particularly limited.

[0041] In this way, by creating a gap space (G) between the first container (10) and the second container (20), when water is filled into the first container (10), the second container (20) can rise by the height of the gap space (G) due to buoyancy, and accordingly, food cooking and heating such as the following are possible.

[0042] (i) When cooking food, that is, when filling the second container (20) with ingredients and broth and filling the first container (10) with water to an appropriate height and heating it, the second container (20) does not float due to the weight of the ingredients and broth in the second container (20), and the bottom surface (21) of the second container (20) is in close contact with the bottom surface (11) of the first container (10) as shown in FIG. 6. Therefore, not only is the heat energy from the water being heated in the first container (10) transferred to the second container (20) and the second container (20) is heated, but the heat energy from the heating of the burner is also directly transferred from the bottom surface (11) of the first container (10) to the bottom surface (21) of the second container (20), so it is possible to cook the food in the second container (20) quickly.

[0043] (ii) When eating food after cooking is complete, the food and broth in the second container (20) gradually decrease, or the user may add more water to the first container (10) at their discretion, so that the second container (20) can float from the first container (10) by buoyancy. At this time, the protrusions (22a, 23a) of the second container (20) are caught on the protrusions (12a, 13a) of the first container to prevent it from rising higher. At this time, a gap is created between the two bottom surfaces (11, 21), so the heat energy from the heating of the burner is not directly transferred to the second container (20) through the bottom surfaces, but the second container (20) is heated indirectly by the water filled in the first container (10), thereby preventing the cooked food in the second container (20) from being overcooked and serving to heat the food to an appropriate temperature.

[0044] (iii) In addition, the water filled in the first container (10) can be used not only to heat the food in the second container (20), but also simultaneously used as a water bath to heat alcohol or beverages such as sake or rice wine.

[0045] In this way, when using the double container according to the present invention, the user can appropriately adjust the water in the first container at their discretion while cooking or eating food after cooking. This allows the second container (20) to be in close contact with the first container (10) during cooking, and after cooking is complete, the second container (20) to be separated from the first container (10) by buoyancy, thereby allowing the cooked food to be heated indirectly. Additionally, there is an advantage that the water in the first container (10) can be used simultaneously for a double boiler to heat alcohol or beverages.

[0046] FIGS. 7 and 8 are drawings illustrating a double container for cooking according to another embodiment, schematically showing a cross-sectional view in which a second container is inserted into a first container.

[0047] FIG. 7 shows a case where the second container (20) is provided with three protrusions (22a, 22b, 22c and 23a, 23b, 23c) of different heights on the first side (22) and the second side (23), respectively, as shown in FIG. 3. At this time, FIG. 7(a) shows the second container (20) inserted into the first container (10) so that the bottom surface of the second container (20) is in close contact with the bottom surface of the first container (10). In this case, as described above, the upward movement of the second container (20) is restricted by the protrusions (12a, 13a) of the first container (10).

[0048] FIG. 7(b) shows a case where the second container (20) is fitted into the first container (10) such that the protrusions (12a, 13a) of the first container (10) are positioned between the first protrusions (22a, 23a) and the second protrusions (22b, 23b) of the second container (20). In this case, it will be understood that the second container (20) can move to any height in the up and down direction due to buoyancy while the protrusions (12a, 13a) of the first container (10) are positioned between the first protrusions (22a, 23a) and the second protrusions (22b, 23b) of the second container (20).

[0049] For example, FIG. 7(b) shows a state in which a second container (20) is floating due to buoyancy by filling a first container (10) with an appropriate amount of water (not shown), and in this state, the second protrusion (22b, 23b) of the second container (20) interferes with the protrusion (12a, 13a) of the first container (10), thereby restricting the upward movement of the second container (20).

[0050] In this way, by providing a plurality of protrusions of different heights on the side of the second container (20), the user may directly heat the second container (20) by filling the first container (10) with an appropriate amount of water according to the cooking process of the second container (20) or the amount of food remaining after cooking, or may heat it indirectly by the water in the first container (10). Additionally, for example, as shown in FIG. 7(b), the user may heat the second container (20) by filling the water in the first container (10) only up to a height lower than the bottom surface (21) of the second container (20). In this case, since the second container (20) does not come into direct contact with the water in the first container (10), the food in the second container (20) may be heated only by the steam of the water evaporating from the first container (10).

[0051] FIG. 8 illustrates an alternative embodiment in which the second container (20) is provided with a concave portion rather than a protrusion. The second container (20) is provided with a concave portion (25a, 26a) capable of receiving the protrusions (12a, 13a) of the first container (10). That is, one side concave portion (25a) of the second container (20) can receive the protrusion (12a) of the first side of the first container (10), and the other side concave portion (26a) of the second container (20) facing it can receive the protrusion (13a) of the second side of the first container (10).

[0052] In this case, in one embodiment, the vertical width of the concave groove (25a, 26a) of the second container (20) may be formed to a width sufficient to accommodate the protrusion (12a, 13a) of the first container. However, in another embodiment, the vertical width of the concave groove (25a, 26a) of the second container (20) may be larger than the vertical protrusion width of the protrusion (12a, 13a) of the first container, as shown in FIG. 8(a), and thus, as shown in FIG. 8(b), when an appropriate amount of water is filled into the first container (10), the second container (20) can rise by buoyancy within the vertical width range of the concave groove (25a, 26a).

[0053] In addition, although not shown in the drawing, in an alternative embodiment, a plurality of concave portions with different heights may be formed on the opposing sides of the second container (20).

[0054] FIGS. 9 to 11 are drawings illustrating a double container for cooking according to another alternative embodiment.

[0055] Referring to FIGS. 9 to 11, in this embodiment, each of the protrusions (12a, 13a) of the first container (10) is composed of a plurality of short horizontal protrusions. For example, in the illustrated embodiment, the protrusion (12a) of the first side (12) may be composed of four short protrusions (12a), and the protrusion (13a) of the second side (13) may also be composed of four short protrusions (13a).

[0056] In addition, the second container (20) is also provided with a short length protrusion. That is, as shown in the plan view of FIG. 10(b), the second container (20) has two short length protrusions (22a, 23a) formed on each of the sides facing each other.

[0057] In this case, if you want to insert the second container (20) into the first container (10), as shown in FIG. 10(a) and FIG. 11, you will understand that after inserting the second container (20) into the first container (10) at a position where the protrusions (22a, 23a) of the second container (20) do not interfere with the protrusions (12a, 13a) of the first container (10), you can push the second container (20) to the left or right to seat the second container (20) inside the first container (10).

[0058] As described above, a person skilled in the art to which the present invention pertains will understand that various modifications and variations are possible from the description in this specification. Therefore, the scope of the present invention should not be limited to the described embodiments, but should be defined by the claims set forth below as well as equivalents thereof.
