Description

[Technical field]

[0001] The present invention relates to a rice ball case. [Background technology]

[0002] Conventionally, portable onigiri cases available on the market are in the shape of a rounded triangular prism, slightly larger than an onigiri, and can store one or two or three onigiri. They are made of plastic or cloth, and are widely distributed in the public. The purpose of putting onigiri in an onigiri case is to protect the onigiri from being crushed while moving and to serve as a packaging cover to prevent food from being put directly into a bag or the like. Places where onigiri are brought with them include parks, schools, workplaces, cram schools, and club activities, and the reasons for bringing onigiri with them are varied, such as not wanting to carry much luggage, not wanting to spend money, not eating as much as a bento, not having time or space to eat a bento, and eating as a supplement to a bento. Thus, there are many situations in daily life where people bring one onigiri with them, even if they do not need a bento. When buying onigiri from a convenience store, you only need to throw away the trash after eating, but if you bring an onigiri case from home, carrying the case home after eating can be a nuisance. As a countermeasure, people sometimes wrap the rice balls in a flat lunch cloth or put them in a plastic bag, but in that case, the rice balls can get mixed up in the bag and get crushed.

[0003] Onigiri made at home are often wrapped in plastic wrap or aluminum foil before storage, but in these cases, the onigiri often have seasoning mixed in or are wrapped in nori seaweed from the beginning. In recent years, as convenience store onigiri have become more prevalent in society, the style of wrapping nori just before eating has become mainstream, rather than onigiri that already have nori wrapped around them. Although it takes time, wrapping nori just before eating allows you to enjoy the fun of completing the onigiri yourself, and you can feel the crispy texture and flavor of the nori, giving you a sense of satisfaction. When wrapping nori seaweed around onigiri on the go, there is no storage space in the onigiri case, so you have to wrap the nori seaweed in plastic wrap, put it in a plastic bag with a zipper, or prepare it separately outside the onigiri case, which makes it difficult to carry. In some cases, onigiri wrapped in plastic wrap or aluminum foil are covered with seaweed wrapped in plastic wrap or aluminum foil and then stored in an onigiri case. However, if there is not enough space in the onigiri case, the seaweed is forced in, which can tear the seaweed.

[0004] When eating onigiri, people often buy instant noodles or prepared foods at convenience stores, or drinks from vending machines, and eat and drink with the onigiri. Depending on the circumstances of the family, such as when both partners work, people may give their family members onigiri for lunch and dinner out, or onigiri for breakfast and lunch at the school cafeteria, and so on. When giving onigiri and cash to children for long hours of extracurricular activities or cram schools, or preparing meals for the elderly, it can be difficult to manage them depending on the age and situation.

[0005] If you prepare side dishes in addition to rice balls, you will need to use a separate lunch box, but this means you will have to carry around a chopstick holder, lunch box, ice packs, etc., which increases the amount of luggage you need to carry. Also, rice ball cases that can be washed and into which you can put rice balls directly, and lunch boxes for side dishes, can emit a putrid odor if you do not wash them immediately after bringing them home. If you are out all day, you will have to carry the rice ball case and lunch box after use and wash them immediately after returning home, which is a hassle.

[0006] After eating onigiri, sometimes seaweed gets stuck on my teeth and lips, and when I'm out I can't check it, which can be embarrassing.

[0007] Various onigiri cases that can store onigiri and seaweed, as well as foldable onigiri cases, have been proposed (see the prior art documents below). [Prior art documents] [Patent documents]

[0008] [Patent Document 1] JP 2015-164480 A [Patent Document 2] Patent Publication No. 2021-36997 [Patent Document 3] Utility Model Registration No. 3149980 [Patent Document 4] Utility Model Registration No. 55-7127526 [Patent Document 5] Japanese Patent Application Publication No. 10-264929 [Patent Document 6] Design Registration No. 1771990 [Patent Document 7] Design Registration No. 1484588 [Patent Document 8] Japanese Utility Model Application Publication No. 6-50520 [Patent Document 9] Utility Model Registration No. 3126414 Summary of the Invention [Problem to be solved by the invention]

[0009] The rice ball case described in Patent Document 1 is a case in which rice is directly put into the rice ball case to form rice balls, which can then be carried around as is. The case must be washed after each use, and the nori seaweed must be stored in it, which requires thorough drying after washing, which is time-consuming. In addition, hard cases do not lose their shape, but they do not change shape even after use, which can be a nuisance. The product of the present invention is different in that it can be folded up to make it compact after use.

[0010] The multifunctional lunch belt described in Patent Document 2 is made of a flexible packaging material and covers a wide variety of shapes (cylinders, triangular prisms, cubes, etc.) and covers the shape of the packaged items such as rice balls, sandwiches, and mochi. This is fine when the item can be carried by hand, but when it is put in a bag or backpack and used on a crowded train, for example, the flexible packaging material does not protect the shape of the food. In addition, when covering multiple items of different shapes, gaps may be formed inside the packaging part, causing the food items to come into contact with each other and lose their shape. This multifunctional lunch belt is fine for items that are well-shaped, such as three rice balls or two sandwiches, but is difficult to use when there is only one rice ball. The multifunctional lunch belt is a belt that holds the food items together, and is not a case or container that protects the food items from being crushed, so its features differ from those of the present invention.

[0011] The onigiri bento box described in Patent Document 3 can store side dishes, rice, and nori seaweed. It has a function to pull out the rice, and the nori seaweed is placed on the rolling mat to roll it up and eat, but this is difficult to do outdoors where there is no table. In addition, it is large like a bento box, and is too large to carry as a light snack when you just want to eat a little. The present invention differs in that it can be folded compactly after use, making it easy to carry.

[0012] The portable container for wrapped nori rice balls described in Patent Document 4 is a container that can form a single rice ball and allow the rice ball formed together with the seaweed to be carried, but the present invention is different in that the side wall portion can be folded inward to make it compact.

[0013] The foldable container described in Patent Document 5 is a container for holding several rice balls, side dishes, sandwiches, etc., and has a capacity the size of a typical lunch box. After use, it can be folded up to become compact, but it also has a lid, inner lid, main body, and fork, so it is time-consuming to put away. The present invention is different in that the side part of the triangular rice ball can be held in a triangular shape by the side wall part, allowing one triangular rice ball to be stored compactly.

[0014] The bamboo bark style lunch cloth with heat and cold insulation described in Patent Document 6 has a mesh pocket for storing ice packs, but it is a lunch cloth that can store rice balls together and is not a case or container that protects them from being crushed, so its features differ from those of the present invention.

[0015] The rice ball storage container described in Patent Document 7 is a storage container made of a foldable flexible sheet body with a sheet material with heat and cold insulation function on the inner side, and is a container suitable for storing three rice balls. It is different in that it stores one rice ball of the present invention. Also, while the rice ball is wrapped in a single sheet, the product of the present invention is different in that it has a foldable side wall that is configured in an upright state and a tilted state.

[0016] The lunch box with a mirror described in Patent Document 8 has a lunch box lid with a mirror attached. Although the lunch box lid allows the user to check the user's mouth, it is difficult to check the user's mouth when there are people around, and it is also difficult to remove dirt from the lid. The present invention is oblong and made of a flexible material, so it can be curved to cover the face. It is different in that it allows the user to check the user's mouth while hiding the face.

[0017] The paper cup lunch box described in Patent Document 9 has a mirror attached to the lunch box lid. Although the lunch box lid allows the user to check the user's mouth, it is difficult to check and remove dirt from the lunch box when there are people around due to the concern of people looking at the user. The present invention is made of a flexible material with a horizontal shape, so it can be curved to cover the face. It is different in that the user can check the user's mouth while hiding the face.

[0018] Conventionally, onigiri cases have had the following drawbacks: (a) A typical onigiri case or lunch box becomes lighter after eating, but the size of the container remains the same, making it inconvenient to carry it home. Also, when a single onigiri is placed in a lunch cloth or plastic bag and carried around, the shape of the onigiri can get crushed. (b) When using a general onigiri case, there is no space to store seaweed, so the onigiri rice balls are either pre-wrapped in seaweed, moist, or have furikake (seasoning) mixed in, meaning that the original crunchy texture of the seaweed cannot be enjoyed. Also, if you want to enjoy a crunchy texture, you have to prepare seaweed separately, which makes it inconvenient to carry around. (C) When giving rice balls and cash to children or elderly people, it can be difficult to manage depending on their age and situation. (2) If rice balls alone were not enough and one wanted to bring side dishes, one had to bring a lunch box, chopstick holder, and ice pack separately, which was troublesome. After using the lunch box, one had to carry around a dirty lunch box and wash it immediately after bringing it home, which was troublesome. (e) When eating rice balls with seaweed, the seaweed would sometimes stick to my teeth, which was difficult to check when I was out. [Means for solving the problem]

[0019] This is a case for storing typical triangular rice balls, A foldable side wall portion configured in an upright state and an inclined state is provided on a rectangular sheet for the purpose of holding a side portion of the triangular rice ball; The foldable side wall portion is erected, and after the rice balls are stored, By wrapping the rectangular sheet underneath the rice ball inside, the rice ball can be kept in its shape without losing its shape. After eating, the foldable side wall parts are inclined so as to overlap inward, and the rectangular sheet is also folded inward to flatten the rice ball case, thereby making it compact.

[0020] The foldable rice ball case according to claim 1 is made by stacking rectangular sheets 1 and 2, sewing the edges together into an L-shape or a U-shape with an opening at the top, and providing a storage compartment like the bill compartment of a wallet, in which seaweed wrapped in plastic wrap or paper money can be stored.

[0021] A box-shaped body that surrounds the rice ball on all four sides is provided on the outside of the side wall that stores the triangular rice ball. The foldable rice ball case according to claim 1 has foldable side walls that can be placed upright or tilted, allowing side dishes to be placed in the free space, and after eating, the side walls of the box-shaped body and the side walls of the rice ball are tilted inward so that they overlap, and the rectangular sheet can also be folded to become flat and compact.

[0022] 2. The foldable rice ball case according to claim 1, wherein a mirror is provided in the center of the rectangular sheet, so that the mouth can be checked while the face is hidden by the rectangular sheet. Effect of the Invention

[0023] According to the onigiri case described in claim 1, you can carry a typical triangular onigiri without losing its shape, and after eating, you can fold it into a flat, compact shape, so it doesn't get in the way when you put it in your bag, making it easy to use. By bringing your staple onigiri with you, you can reduce the cost of eating out and the hassle of going out to buy them.

[0024] According to the onigiri case described in claim 2, a storage section like the billfold of a wallet is provided in the rectangular sheet, so that seaweed and bills can be stored inside. The nori wrapped in plastic wrap can be stored unfolded together with the onigiri, allowing you to enjoy the crispy texture of the seaweed like you would get from a convenience store onigiri, giving you a sense of satisfaction. You can also put bills in it, so busy parents can encourage their children to bring their own onigiri and buy the rest, and give them all together.

[0025] According to the onigiri case described in claim 3, a foldable side wall section is provided on the outside of the side wall section that stores the triangular onigiri, which is a box-shaped body that surrounds the onigiri on all four sides and can be configured in an upright or tilted state, and side dishes can be placed in the empty space, making this an onigiri case that is just right for people who are not satisfied with just onigiri, although not as much as a bento. In the empty space, for example, naturally thawed fried chicken wrapped in plastic wrap can be placed, or boiled eggs wrapped in plastic wrap can be placed, and all wrapped in plastic wrap can be stored in the gaps. In this way, if you eat with one hand without using chopsticks or a fork, holding the plastic wrap, there is no washing up, making cleanup easy. Also, naturally thawing frozen foods instead of using ice packs can prevent food poisoning and save the effort of preparing them.

[0026] According to the rice ball case described in claim 4, a mirror is provided in the center of the rectangular sheet, and the rectangular sheet can be curved to cover the face, allowing the user to check for dirt around the mouth, smudged lipstick, etc. This allows the user to check while hiding their face without worrying about the surroundings, providing peace of mind even when out and about.

[0028] An embodiment of the present invention will be described with reference to FIG. 1. FIG. 1 is an exploded view of a rice ball case. A rectangular sheet 1 and a rectangular sheet 2 are stacked, and the edges are sewn into an L-shape or a U-shape with an opening at the top, forming the rectangular sheets 1 and 2 into a bag-like shape like the billfold of a wallet. On the rectangular sheet 2, two folded side walls formed by an upper wing 6 and a lower wing 7 are provided in a V-shape. The upper wing 6 and the lower wing 7 are one sheet, and have a fold line 4 in the center, and only the base part of the lower wing 7 is placed on the rectangular sheet 2. The lower wing 7 is an isosceles trapezoid, and the upper wing 6 is shaped like the letter D with a slightly protruding tip. The shapes of the upper wing 6 and the lower wing 7 can be regular hexagons, but the shape of the upper wing 6 like the letter D with a slightly protruding tip compared to a regular hexagon makes it easier to store large rice balls. Two wing parts 6, one on the inside and the other on the outside, have a pair of wing part hook-and-loop fastener convex 8 and wing part hook-and-loop fastener concave 9. Rectangular sheet 2 has sides 5 and a cover 3, and a hook-and-loop fastener convex 10 is provided on the inside of cover 3, and a pair of hook-and-loop fastener concave 11 is provided on the end opposite to hook-and-loop fastener convex 10 on the outer surface of rectangular sheet 1. Rectangular sheet 2 has a pocket 13, which can be opened and closed by a pocket closing part 12. Inside is a pocket for putting coins, plastic wrap waste, ice packs, etc. A mirror 14 is provided in the center of rectangular sheet 2.

[0029] An embodiment of the present invention will be described with reference to Fig. 2. Fig. 2 is an overhead view of rice balls and nori seaweed in the middle of being stored. Rectangular sheet 1 and rectangular sheet 2 are overlapped to form a bag-like shape, and nori seaweed 16 wrapped in plastic wrap, half the size of a sheet of nori seaweed, is stored inside rectangular sheet 2. Wing portions 7 are raised to form side walls, and rice balls 17 wrapped in plastic wrap are stored inside. The hook-and-loop fastener protrusions 8 and hook-and-loop fastener recesses 9 on the wings are adjusted to the size of the rice ball, and then closed and joined by overlapping while tightly fitting them together.

[0030] An embodiment of the present invention will be described with reference to Figure 3. Figure 3 is an overhead view of a regular-sized rice ball (approximately 130g) that has been joined to encase it. The overlapping area of ​​the two upper wings 6 is where the hook-and-loop tapes 8 and 9 are joined. The hook-and-loop tapes are joined by fixing them at the bends along the shape of the rice ball, so that a triangular shape that matches the size of the rice ball can be formed and held in place.

[0031] An embodiment of the present invention will be described with reference to FIG. 4. FIG. 4 shows a side view of the rice ball holder and an enlarged view of rectangular sheets 1 and 2. The shape of rice ball 17 wrapped in plastic wrap is maintained by the side wall of lower wing 7, and the hook-and-loop fastener convex 8 and hook-and-loop fastener concave 9 of the overlapping wing upper wing 6 are joined together. The enlarged view shows the inside of bag-shaped rectangular sheets 1 and 2, which contain seaweed 16 wrapped in plastic wrap. Inside rectangular sheet 1, there are three layers: outer wrapping material 1a, intermediate material 1b, and inner material 1c. Intermediate material 1b is a taut, thin board, and outer wrapping material 1a and inner material 1c are dough. Similarly, inside rectangular sheet 2, there are three layers: outer wrapping material 2a, intermediate material 2b, and inner material 2c. In this way, the intermediate material provides tension, and even if the sheet is thin, the shape of the rice ball can be protected.

[0032] An embodiment of the present invention will be described with reference to Fig. 5. Fig. 5 is an overhead view of a convenience store-sized rice ball 17 (approximately 110g) wrapped in plastic wrap being fixed in place. This shows the area where the two upper wing pieces 6 overlap and are joined. The area of ​​the wing hook-and-loop fastener convex 8 and the wing hook-and-loop fastener concave 9 is large, allowing for a firm fixation.

[0033] An embodiment of the present invention will be described with reference to Fig. 6. Fig. 6 is an overhead view of a rice ball 17 (approximately 160g) wrapped in plastic wrap and fixed to fit in a rice bowl. This shows the joint where the two upper wing parts 6 overlap. The surface area of ​​the wing hook-and-loop fastener convex part 8 and the wing hook-and-loop fastener concave part 9 is shallow, but the upper wing parts 6 overlap near their apexes, so they are firmly fixed in place. Rice balls made at home tend to be somewhat large, and frozen rice packs are often thawed and wrapped in plastic wrap to make onigiri. In this way, even if the size of the rice ball changes, it can be accommodated by the overlap of the upper wing parts 6.

[0034] An embodiment of the present invention will be described with reference to Fig. 7. Fig. 7 is a perspective view of rice balls stored and standing upright. Handle 15 makes it easy to carry.

[0035] An embodiment of the present invention will be described with reference to Fig. 8. Fig. 8 is a side view of the container with rice balls stored and turned sideways. The lower wing portion 7 forms a side wall, which prevents the rice balls 17 wrapped in plastic wrap from falling out. The fold lines 4 form a box-like body, eliminating wasted space and allowing the rice balls to be neatly stored.

[0036] An embodiment of the present invention will be described with reference to Fig. 9. Fig. 9 is an overhead view of the folded wing parts. The two left and right wing parts 6 and 7 are folded flat and stacked. At this time, one side of the hook-and-loop fastener is placed at the top so that the hook-and-loop fasteners 8 and 9 do not overlap, and the fastener surfaces do not join, making it easy to use the next time.

[0037] An embodiment of the present invention will be described with reference to Fig. 10. Fig. 10 is a side view of the wing portion folded. When the wing portion is folded, it becomes flat. By placing one side of the hook-and-loop fastener at the top so that hook-and-loop fasteners 8 and 9 do not overlap, the fastener surfaces do not join together, making it easy to use the next time.

[0038] An embodiment of the present invention will be described with reference to Fig. 11. Fig. 11 is an overhead view of folding. A bag-shaped rectangular sheet is folded in half along fold line 4, and the hook-and-loop fastener protrusion 10 and the hook-and-loop fastener recess 11 under the cover lid 3 are joined together to close the bag, making it compact.

[0039] An embodiment of the present invention will be described with reference to Fig. 12. Fig. 12 is a side view of folding. The fold line 4 makes it easier to fold in half and results in a flatter shape. EXAMPLES

[0040] An embodiment of the present invention will be described with reference to Fig. 13. Fig. 13 is an overhead development view of a rice ball case that can also hold side dishes. A rectangular sheet 1 and a rectangular sheet 2 are overlapped to form a bag-like rectangular sheet 2, on which four side walls (two side walls 22 and two side walls 24) are fixed to form a box-like body, and two side walls (two side walls 23) are fixed inside in a V-shape, leaving a triangular space. It is possible to store rice balls in the triangular space, and to put small amounts of side dishes in the two spaces on either side.

[0041] An embodiment of the present invention will be described with reference to Fig. 14. Fig. 14 is an overhead view of rice balls, side dishes, and nori seaweed being stored in an onigiri case that can also hold side dishes. Rice balls 17 wrapped in plastic wrap are stored in the triangular space in the center, and side dishes 18 wrapped in plastic wrap (e.g. frozen fried chicken wrapped in plastic wrap, boiled eggs wrapped in plastic wrap, frozen broccoli wrapped in plastic wrap, cherry tomatoes wrapped in plastic wrap, etc.) are stored in the two spaces on either side. Rectangular sheets 1 and 2 are overlapped to form a bag-like rectangular sheet 2, which stores seaweed 16 wrapped in plastic wrap and half the size of a sheet of nori seaweed.

[0042] An embodiment of the present invention will be described with reference to Fig. 15. Fig. 15 is a perspective overhead view of rice balls and side dishes stored in the container. When viewed from an angle, it can be seen that rice balls 17 and side dishes 18 wrapped in plastic wrap are surrounded by side walls (22, 23, 24).

[0043] An embodiment of the present invention will be described with reference to Fig. 16. Fig. 16 is a side view of a container filled with rice balls and side dishes. The trapezoidal side wall fold 22 has trapezoidal fold 4 and is designed to be easily folded inward, but the material of the side wall is taut, so it is less likely to fall over if side dishes are stuffed into it.

[0044] An embodiment of the present invention will be described with reference to Fig. 17. Fig. 17 shows a side view of a rice ball container with trapezoidal folds 22. Like the rectangular sheets 1 and 2, the side walls are made of three layers: an outer layer, an intermediate layer, and an inner layer, with the intermediate layer being a taut board and the outer layer and inner layer being dough. There are trapezoidal folds 4, making it easy to fold inwards and stand on its own.

[0045] An embodiment of the present invention will be described with reference to Fig. 18. Fig. 18 is a side view of the rice ball storage with an isosceles triangle fold 23. As in the above, there is an isosceles triangle side wall fold 4, making it easy to fold inwards.

[0046] An embodiment of the present invention will be described with reference to Fig. 19. Fig. 19 is a side view of a rice ball storage container with no fold lines 24. There are no fold lines on the side walls, and the container has a rectangular structure that makes it easy to fold inwards.

[0047] An embodiment of the present invention will be described with reference to Fig. 20. Fig. 20 is a diagonal overhead view of the rice ball container in the middle of being folded for storage. When the side wall portion 24 and the fold lines 4 of the side wall portions 22, 24 are folded inward and pressed toward the center, the container changes from an upright state to an inclined state, and the box-shaped body is folded into a flat state.

[0048] An embodiment of the present invention will be described with reference to Figure 21. Figure 21 is an overhead view of the rice ball storage fold. The trapezoidal fold 22 and isosceles triangle 23 on the side wall are folded inward along the fold 4, and the unfolded triangle 24 is folded inward as is, resulting in a flat box-shaped body. The right angle at the apex of the isosceles triangle 23 on the side wall is folded to the left or right. The folding method is similar to an origami trick boat or morning glory, and the combination of triangles and squares allows it to be folded flat.

[0049] An embodiment of the present invention will be described with reference to Fig. 22. Fig. 22 is an upright perspective view of the container containing rice balls and side dishes. The container is wrapped with fixing band 19 so that the contents do not spill out of side wall 22, and the whole container is fixed in place by joining convex hook-and-loop fastener 20 and concave hook-and-loop fastener 21 at the center of the front. A handle 15 is attached to the top, making it easy to carry.

[0050] An embodiment of the present invention will be described with reference to Fig. 23. Fig. 23 is an overhead view of folding. A bag-shaped rectangular sheet is folded in half along fold line 4, and hook-and-loop fastener convex 10 and hook-and-loop fastener concave 11 under cover lid 3 are joined to close the bag so that the bag is flattened, and hook-and-loop fastener convex 20 and hook-and-loop fastener concave 21 on fixing band 19 are joined to fasten the bag.

[0051] An embodiment of the present invention will be described with reference to Fig. 24. Fig. 24 is a side view of folding. The presence of fold line 4 makes it easy to fold the bag-shaped rectangular sheet in half.

[0052] An embodiment of the present invention will be described with reference to Fig. 25. Fig. 25 is a front view of the mirror when in use. A mirror 14 is provided in the center of rectangular sheet 2, and the bag-shaped rectangular sheet in a flattened state is spread out in the horizontal direction and curved to cover the face, hiding the face while allowing the wearer to see the mirror 14 in the center of rectangular sheet 2 and check the mouth.

[0053] An embodiment of the present invention will be described with reference to Fig. 26. Fig. 26 is a perspective view of the mirror when in use. Since not only the mouth but also the side of the face can be hidden as described above, the face can be hidden from those around when checking. [Industrial Applicability]
