Abstract
Description
Food packaging components
[0001] The present invention relates to a food packaging member, and more specifically, to a packaging member capable of separating materials with different cooking temperatures during food packaging, blocking microwaves from materials with lower cooking temperatures during microwave heating, and utilizing it as a means to resolve slow heating of the inside of the food while the outside is being heated during microwave use.
[0002] Microwave ovens can heat food by irradiating it with microwaves, a type of electromagnetic wave, while the food is placed inside the case. As the use of microwave ovens has become widespread, microwave-safe packaged foods are widely distributed in the market, not only in large supermarkets but also in small general stores, so that food can be heated conveniently.
[0003] These packaged foods contain a variety of ingredients, each with a suitable cooking temperature. For example, in the case of a hamburger, vegetables such as lettuce, tomatoes, and pickles are placed as fillings between the outer ingredients—a patty, cheese, bacon, and a bun.
[0004] Here, outer ingredients such as patties, cheese, bacon, and bread require heating, so the cooking temperature tends to be high. However, vegetables need to be kept at room temperature or even chilled, so the cooking temperature tends to be low.
[0005] Therefore, when a hamburger is cooked in a microwave, the outer ingredients are heated properly, but the vegetables inside are also heated, which can degrade the taste and texture.
[0006] The objective of the present invention is to provide a packaging member capable of separating materials with different cooking temperatures during food packaging and blocking microwaves from a microwave oven to materials with a lower cooking temperature.
[0007] To achieve the above objective, a food packaging member according to one embodiment of the present invention may include an outer material in which a first material and a second material are disposed inside, and an inner material disposed inside the outer material to separate the first material and the second material.
[0008] An exterior material or an interior material according to one embodiment of the present invention may be formed from a material including a microwave shielding material.
[0009] An exterior material or an interior material according to one embodiment of the present invention may be at least one metal material among aluminum, stainless steel, copper, and nickel, at least one carbon-based material among graphene and carbon nanotubes, at least one conductive polymer among PEDOT and polyaniline, or any one of composite materials thereof.
[0010] A through hole may be formed in the exterior material and the interior material according to one embodiment of the present invention.
[0011] A through hole according to one embodiment of the present invention may be at least one of a single circle, a plurality of circles, an ellipse, a straight line, a random, a grid, a mesh, a symmetrical shape, and an asymmetrical shape.
[0012] In an interior material according to one embodiment of the present invention, the density of a certain area may be higher than the density of the remaining area.
[0013] A food packaging member according to one embodiment of the present invention may include an exterior material comprising a first exterior material disposed on the upper part of a first material and a second exterior material disposed on the lower part of the first material.
[0014] An interior material according to one embodiment of the present invention may include a first interior material disposed on the upper part of a second material and a second interior material disposed on the lower part of the second material.
[0015] A first interior material according to one embodiment of the present invention may include a first-1 interior material and a first-2 interior material that overlaps with a part of the first-1 interior material or is spaced apart from each other.
[0016] According to one embodiment of the present invention, the length of the interior material may be shorter or longer than the length of the exterior material.
[0017] A joint may be formed at the end of an exterior material or an end of an interior material according to one embodiment of the present invention.
[0018] According to one embodiment of the present invention, the left end of the interior material may be interposed between the left end of the first exterior material and the left end of the second exterior material and joined together, and the right end of the interior material may be interposed between the right end of the first exterior material and the right end of the second exterior material and joined together with the exterior material.
[0019] According to one embodiment of the present invention, the left end of the first exterior material and the left end of the second exterior material are joined, and the right end of the first exterior material and the right end of the second exterior material can be joined.
[0020] According to one embodiment of the present invention, the velvet of the first interior material can be interposed between the velvet of the first exterior material and the velvet of the second exterior material and joined together.
[0021] According to one embodiment of the present invention, the left end of the second interior material can be interposed between the left end of the first exterior material and the left end of the second exterior material and joined together.
[0022] According to one embodiment of the present invention, the velvet of the first interior material can be interposed between the velvet of the first exterior material and the velvet of the second exterior material and joined together.
[0023] According to one embodiment of the present invention, the velvet of the second interior material can be interposed between the velvet of the first exterior material and the velvet of the second exterior material and joined together.
[0024] A cut-out groove may be formed in at least one of the left end, right end, front end, and rear end of the exterior material according to one embodiment of the present invention.
[0025] A perforation line may be formed in the exterior material according to one embodiment of the present invention.
[0026] A food packaging member according to one embodiment of the present invention can be formed in various forms such as paper, boxes, strips, containers, etc., in addition to vinyl, so it can be applied to the packaging of various foods.
[0027] In addition, since the interior material is placed inside the exterior material, the space inside the exterior material can be partitioned, allowing for the separation of materials with different cooking temperatures.
[0028] In addition, the interior material is formed from a material containing a microwave shielding material, so microwaves can be blocked for materials with low cooking temperatures, thereby maintaining a room temperature state or minimizing the increase in temperature.
[0029] In addition, microwaves can be partially irradiated onto the material through the perforations formed in the interior material, allowing for precise control of the heating level. Therefore, since food can be cooked at various temperature ranges from rapid to medium or minimal heating, it can be applied not only to refrigerated foods but also to frozen foods, and can be utilized as a means to resolve the issue of slow heating on the inside of food while the outside is being heated during microwave use.
[0030] In addition, through a multi-layered structure consisting of exterior and interior materials, the advantages of each material can be combined to effectively preserve the freshness, safety, and quality of food, while simultaneously maximizing the functionality and convenience of the packaging.

[0047] In addition, in describing the present invention, if it is determined that a detailed description of related known components or functions may obscure the essence of the invention, such detailed description is omitted.
[0048]
[0049] Hereinafter, a food packaging member according to the first embodiment of the present invention will be described.
[0050] FIG. 1 is a plan view of a food packaging member according to a first embodiment of the present invention, FIG. 2 is an exploded perspective view of the food packaging member shown in FIG. 1, FIG. 3 is a cross-sectional view showing a first embodiment of an exterior material, FIG. 4 is a cross-sectional view showing a second embodiment of an exterior material, and FIG. 5 is a plan view of an interior material.
[0051] Referring to FIGS. 1 to 5, the food packaging member (100-1) may include an outer material (110) and an inner material (120-1). A food ingredient (200) may be placed inside the outer material (110). The ingredient (200) may include a first ingredient (210) and a second ingredient (220). The food may be any packaged food including hamburgers, sandwiches, hot dogs, paninis, kebabs, wraps, gyros, nachos and sauces, tacos, burritos, fajita wraps, tortillas, gimbap, rolls, banh mi, etc.
[0052] For ease of explanation, the food is described below as a hamburger as an example. The first ingredient (210) may be an outer ingredient such as a patty, cheese, bacon, or bread. The second ingredient (220) may be a filling ingredient with a lower cooking temperature than the first ingredient (210), such as vegetables.
[0053] The interior material (120-1) is placed inside the exterior material (110) to partition a space (300) inside the exterior material (110). Additionally, the interior material (120-1) is interposed between the first material (210) and the second material (220) to separate the first material (210) and the second material (220).
[0054] The first material (210) may consist of a pair. The second material (220) may consist of a single material. Here, the number of the first material (210) and the second material (220) is not limited to this and can be selectively adjusted depending on the food.
[0055] The first material (210) may include a first-1 material (211) and a first-2 material (212). The first-1 material (211) may be placed on the upper side of the second material (220). The first-2 material (212) may be placed on the lower side of the second material (220).
[0056] The exterior material (110) may include a first exterior material (111) and a second exterior material (112). The first exterior material (111) may be placed on top of the first-1 material (211) to cover the first-1 material (211). The second exterior material (112) may be placed on bottom of the first-2 material (212) to cover the first-2 material (212).
[0057] The interior material (120-1) may include a first interior material (121) and a second interior material (122). The first interior material (121) may be placed on the upper part of the second material (220) and interposed between the first-1 material (211) and the second material (220). The second interior material (122) may be placed on the lower part of the second material (220) and interposed between the first-2 material (212) and the second material (220).
[0058] That is, a first space (310) is formed between the first exterior material (111) and the first interior material (121) so that the first-1 material (211) can be placed. A second space (320) is formed between the first interior material (121) and the second interior material (122) so that the second material (220) can be placed. A third space (330) is formed between the second interior material (122) and the second exterior material (112) so that the first-2 material (212) can be placed.
[0059] A joint may be formed in the exterior material (110) or the interior material (120) to seal the exterior material (110). First, an exterior joint (150) may be formed at the end of the exterior material (110). The exterior joint (150) may be formed by heat-fusion joining the end of the first exterior material (111) and the end of the second exterior material (112) while they are in contact with each other.
[0060] The exterior joint (150) may include a first exterior joint (151), a second exterior joint (152), a third exterior joint (153), and a fourth exterior joint (154). More specifically, the first exterior joint (151) may be formed by joining the left end of the first exterior material (111) and the left end of the second exterior material (112). The second exterior joint (152) may be formed by joining the right end of the first exterior material (111) and the right end of the second exterior material (112).
[0061] The third exterior joint (153) can be formed by joining the front end of the first exterior material (111) and the front end of the second exterior material (112). The fourth exterior joint (154) can be formed by joining the rear end of the first exterior material (111) and the rear end of the second exterior material (112).
[0062] Here, if the exterior material (110) is a single sheet, the exterior material (110) wraps the material (200) from top to bottom, and then the left end of the exterior material (110) is joined to form a first exterior joint (151).
[0063] Additionally, the right end of the exterior material (110) may be joined to form a second exterior joint (152). Furthermore, the front end of the exterior material (110) may be joined to form a third exterior joint (153), so that a fourth exterior joint (154) may be omitted.
[0064] An internal joint (160) may be formed at the end of the internal material (120). The internal joint (160) may be formed by interposing the end of the internal material (120) between the end of the first exterior material (111) and the end of the second exterior material (112) and joining it together with the exterior material (110). Accordingly, the space (300) formed between the exterior material (110) and the internal material (120) can be sealed.
[0065] The internal joint (160) may include a first internal joint (161) and a second internal joint (162). The lengths (d1, d2, see FIG. 2) of the exterior material (110) and the interior material (120) may be formed to correspond to each other or similarly.
[0066] The first internal joint (161) can be formed by interposing the left end of the internal material (120) between the left end of the first external material (111) and the left end of the second external material (112) and joining it together with the external material (110).
[0067] Additionally, the second internal joint (162) can be formed by interposing the right end of the internal material (120) between the right end of the first external material (111) and the right end of the second external material (112) and joining it together with the external material (110).
[0068] A plurality of cutting grooves (116, see FIG. 1) may be formed along the length direction of the exterior joint (150), that is, on the left or right end of the exterior material (110). A consumer can easily tear the exterior material (110) along the vertical direction of the exterior joint (150) through the cutting grooves (116) while holding the exterior material (110).
[0069] The exterior material (110) may be formed as a single aluminum sheet as shown in FIG. 3, but is not limited thereto and various packaging materials may be used. Additionally, the exterior material (110') may include an aluminum sheet (114), a PP (polypropylene) film (115), and an LLDPE (linear low-density polyethylene) film (113) as shown in FIG. 4.
[0070] The PP film (115) can be in contact with one side of the aluminum sheet (114). The LLDPE film (113) can be in contact with the other side of the aluminum sheet (114). The PP film (115) can be placed on the outer surface of the outer material (110) to form an outer protective layer of the packaging.
[0071] The PP film (115) provides a base for printing and design, allowing it to be printed with ink. Additionally, the PP film (115) blocks oxygen and moisture to some extent, thereby maintaining the quality of the food inside for a certain period of time.
[0072] In addition, the PP film (115) can protect the interior from external impacts and improve the durability of the packaging. Here, various packaging films including PS film, PET film, and NY (nylon) film may be used instead of the PP film (115).
[0073] The aluminum sheet (114) can be placed on the inner surface of the PP film (115). The aluminum sheet (114) can block external elements such as oxygen, moisture, and light, thereby preserving the freshness and quality of the food inside for a certain period of time. Here, the aluminum sheet (114) is not limited to, and various packaging materials may be used in place of the aluminum sheet (114).
[0074] The LLDPE film (113) can be placed on the inner surface of the aluminum sheet (114). The LLDPE film (113) can come into contact with food. At this time, the LLDPE film (113) can ensure safety even when in direct contact with food.
[0075] In addition, the LLDPE film (113) can effectively seal food to prevent leakage. Here, various packaging films including LDPE film, HDPE film, and MDPE film may be used instead of the LLDPE film (113).
[0076] The exterior material (110) or the interior material (120) may be formed from a material including a microwave shielding material. For example, the exterior material (110) or the interior material (120) may be provided with one of the following: a metal material such as aluminum, stainless steel, copper, nickel, a carbon-based material such as graphene, carbon nanotubes, a conductive polymer such as PEDOT, polyaniline, or a composite material thereof, but is not limited thereto.
[0077] The microwave shielding material may have at least one of the forms of powder, particle, flake, and pellet. That is, since the density varies depending on the form of the microwave shielding material, the microwave shielding rate of the internal material (120) can be controlled by adjusting the density.
[0078] Accordingly, the density of a certain area (123, see FIG. 5) of the interior material (120) can be formed higher than the density of the remaining area (124). That is, in the area with low density, the microwave shielding rate is reduced, so the temperature of the second material (220) rises relatively, allowing for heating and cooking. And, in the area with high density, the microwave shielding rate is increased, so the temperature of the second material (220) can be maintained at a low level.
[0079] Additionally, as the thickness of the interior material (120) increases, the microwave shielding rate may increase. Therefore, the thickness of a certain area (123) of the interior material (120) may be formed to be thicker than the thickness of the remaining area (124).
[0080] FIG. 6 shows various shapes of through holes formed in an interior material, FIG. 7 is a cross-sectional view showing a first embodiment of an interior material, and FIG. 8 is a cross-sectional view showing a second embodiment of an interior material.
[0081] Referring to FIGS. 6 to 8, through holes (130) may be formed in the interior material (120). As shown in FIG. 6, the through holes (130) may be formed in various shapes, such as a single circular shape (131), a random shape (132), multiple circular shapes (133), a straight shape (134), a grid shape (135), a mesh shape (136), an asymmetrical shape (137), and an elliptical shape (138).
[0082] That is, microwaves can be irradiated onto the second material (220) through the holes (130), so the cooking temperature of the second material (220) can be precisely controlled. In addition, the cooking temperature of the second material (220) can be controlled more precisely depending on the shape, size, number, arrangement, and density of the holes (130).
[0083] For example, if the size of the through hole (130) is enlarged, the microwave shielding rate is reduced, allowing the second material (220) to be heated rapidly to a high temperature. For another example, if the size of the through hole (130) is reduced, the microwave shielding rate is increased, allowing the heating level of the second material (220) to be maintained at an intermediate or minimum level.
[0084] As another example, the number of holes (130) can be reduced or the density increased to increase the microwave shielding rate.
[0085] As another example, the position of the through hole (130) may be positioned adjacent to the microwave transmitter of the microwave oven or positioned perpendicular to the direction of microwave propagation to adjust the microwave shielding rate.
[0086] The food packaging member (100-1) may be formed in the form of paper, a box, a strip, or a container in addition to vinyl. Also, the food packaging member (100-1) may be used as a food packaging material other than a lunch box.
[0087] Here, the food packaging member (100-1) may primarily target refrigerated food. In this case, a through hole (130) may not be formed in the inner material (120-1). However, when the food packaging member (100-1) is applied to frozen food, a through hole (130) may be formed in the inner material (120-1).
[0088] The food packaging member (100-1) may further include a transparent film (140). The transparent film (140) allows microwaves to pass through so that the second material (220, see FIG. 2) can be partially heated and cooked.
[0089] Also, the transparent film (140) can close the through hole (130) so that the first material (210, see FIG. 2) and the second material (220) can be prevented from flowing in and mixing through the through hole (130).
[0090] The transparent film (140) may be in contact with only one side of the interior material (120). Additionally, the transparent film (140) may be bonded to both sides of the interior material (120). The transparent film (140) may include a first film (141) and a second film (142). The first film (141) may be bonded to one side of the interior material (120). The second film (142) may be bonded to the other side of the interior material (120).
[0091]
[0092] Hereinafter, a food packaging member according to a second embodiment of the present invention will be described. Prior to the description, specific details regarding components that overlap with the first embodiment described above will be omitted.
[0093] FIG. 9 is an exploded perspective view of a food packaging member according to a second embodiment of the present invention.
[0094] Referring to FIG. 9, the length (d2) of the interior material (120-2) may be formed to be shorter than the length (d1) of the exterior material (110). Accordingly, the interior joint (160, see FIG. 2) described above in the interior material (120-2) may be omitted. Also, the space (300) formed inside the exterior material (110) may be mutually connected.
[0095] That is, the second material (220) can be microwave-blocked by the internal material (120-2), but the moisture and heat released while the first material (210) is cooked can be transferred to the second material (220), allowing the second material (220) to be wet-heat cooked.
[0096]
[0097] Hereinafter, a food packaging member according to the third embodiment of the present invention will be described. Prior to the description, specific details regarding configurations that overlap with the previously mentioned first and second embodiments will be omitted.
[0098] FIG. 10 is a plan view of a food packaging member according to a third embodiment of the present invention, and FIG. 11 is an exploded perspective view of the food packaging member shown in FIG. 10.
[0099] Referring to FIGS. 10 and 11, the interior material (120-3) may include four interior materials. More specifically, the first interior material (121) may include a first-1 interior material (121a) and a first-2 interior material (121b). The second interior material (122) may include a second-1 interior material (122a) and a second-2 interior material (122b).
[0100] The right end of the first-1 inner material (121a) and the left end of the first-2 inner material (121b) may partially overlap and be interposed between the first-1 material (211) and the second material (220). The right end of the second-1 inner material (122a) and the left end of the first-2 inner material (121b) may partially overlap and be interposed between the second material (220) and the first-2 material (212).
[0101] When the inner material (120-3) is overlapped, the thickness increases, and the microwave shielding rate can be higher than that of other areas. Therefore, the overlapped area (125, see FIG. 11) of the inner material (120) is formed with a lower density than the remaining area, so that the microwave shielding rate can be evenly controlled across the entire surface area of the inner material (120-3).
[0102] A perforation line (117, see FIG. 10) may be formed along the length direction of the exterior joint (150) on the exterior material (110). That is, when a consumer pulls the exterior joint (150) to the left and right while holding it, the exterior material (110) can be opened by tearing it to the left and right along the perforation line (117). Also, since the exterior material (110) is connected to the interior material (120-3) through the joint (150, 160), the interior material (120-3) can be separated from the material (200) together with the exterior material (110), allowing the consumer to conveniently consume the food.
[0103]
[0104] Hereinafter, a food packaging member according to the fourth embodiment of the present invention will be described. Prior to the description, specific descriptions of configurations that overlap with the previously mentioned first to third embodiments will be omitted.
[0105] FIG. 12 is an exploded perspective view of a food packaging member according to a fourth embodiment of the present invention.
[0106] Referring to FIG. 12, unlike the third embodiment, the fourth embodiment of the present invention may form a slit (126) by separating the right end of the first-1 inner material (121a) and the left end of the first-2 inner material (121b) by a certain distance from each other. Additionally, the right end of the second-1 inner material (122a) and the left end of the first-2 inner material (121b) may form a slit (126) by separating them by a certain distance from each other.
[0107]
[0108] Hereinafter, a food packaging member according to the fifth embodiment of the present invention will be described. Prior to the description, specific descriptions of configurations that overlap with the previously mentioned first to fourth embodiments will be omitted.
[0109] FIG. 13 is an exploded perspective view of a food packaging member according to the fifth embodiment of the present invention.
[0110] Referring to FIG. 13, the length (d2) of the interior material (120-5) may be formed to be shorter than the length (d1) of the exterior material (110). The right end of the first interior material (121) may be interposed between the right end of the first exterior material (111) and the right end of the second exterior material (112) and joined together. The left end of the second interior material (122) may be interposed between the left end of the first exterior material (111) and the left end of the second exterior material (112) and joined together.
[0111] That is, the inner material (120-5) can be interposed between the materials (200) in a zigzag pattern. Also, the left end of the first inner material (121) and the right end of the second inner material (122) are not joined together with the outer material (110), so that the first space (310) and the second space (320) can be interconnected. Also, the second space (320) and the third space (330) can be interconnected, so wet heating cooking is possible as in the second embodiment described above.
[0112]
[0113] Hereinafter, a food packaging member according to the sixth embodiment of the present invention will be described. Prior to the description, specific descriptions of configurations that overlap with the previously mentioned first to fifth embodiments will be omitted.
[0114] Referring to FIG. 14, the length (d2) of the interior material (120-6) may be formed to be shorter than the length (d1) of the exterior material (110). The right end of the first interior material (121) may be interposed between the right end of the first exterior material (111) and the right end of the second exterior material (112) and joined together.
[0115] The right end of the second interior material (122) can be interposed between the right end of the first exterior material (111) and the right end of the second exterior material (112) and joined together. That is, a joint may not be formed on the left end of the interior material (120-6). Also, a joint (162) may be formed only on the right end of the interior material (120-6).
[0116] A cutting groove (118) may be formed at the front or rear end of the outer material (110). That is, the cutting groove (118) is located on the side where the inner material (120-6) is joined, so that the consumer can naturally specify the opening location. Also, as the consumer tears the outer material (110), the inner material (120-6) can be naturally separated, allowing the food to be consumed conveniently.
[0117]
[0118] As described above, the food packaging member according to one embodiment of the present invention can be formed in various forms such as paper, boxes, strips, containers, etc., in addition to vinyl, so it can be applied to the packaging of various foods.
[0119] In addition, since the interior material is placed inside the exterior material, the space inside the exterior material can be partitioned, allowing for the separation of materials with different cooking temperatures.
[0120] In addition, the interior material is formed from a material containing a microwave shielding material, so microwaves can be blocked for materials with low cooking temperatures, thereby maintaining a room temperature state or minimizing the increase in temperature.
[0121] In addition, microwaves can be partially irradiated onto the material through the perforations formed in the interior material, allowing for precise control of the heating level. Therefore, since food can be cooked over a wide range of temperatures, from rapid to medium or minimal heating, it can be applied not only to refrigerated foods but also to frozen foods.
[0122] In addition, through a multi-layered structure consisting of exterior and interior materials, the advantages of each material can be combined to effectively preserve the freshness, safety, and quality of food, while simultaneously maximizing the functionality and convenience of the packaging.
