Description

Applicable under Article 30, Paragraph 2 of the Patent Act. Exhibited and unveiled at the Delicatessen Trade Show 2021 from February 17, 2021 to February 19, 2021.

Application of Article 30, Paragraph 2 of the Patent Act An introduction video was posted and made public on a video sharing site on December 3, 2020.

The present invention relates to a square-shaped block of rice in which ingredients are placed in a square space in the center and the whole is wrapped in a wrapping sheet.

Conventionally, there are various products available at convenience stores, supermarkets, etc., in which cooked rice containing ingredients is packaged in a packaging sheet. For example, there are rice balls in which cooked rice is formed into an approximately triangular shape and rice balls in which cooked rice is formed into an approximately round shape.

However, most onigiri currently on the market are made by encasing the ingredients inside, meaning that the ingredients inside cannot be seen from the outside, and consumers often have to choose a product based on the text and pictures on the packaging.

On the other hand, there are products whose flavors can be visually distinguished even through the packaging.
For example, there are various types of products, such as cooked rice or mixed rice, which is a mixture of cooked rice and ingredients, or a round rice ball with a small depression formed in the approximate center and ingredients embedded in the depression.

On the other hand, there are molded containers that are designed to hold the shape of a bowl-shaped block of cooked rice after it is placed in the container and heated, and then topped with ingredients.

As mentioned above, if the ingredients are exposed and not wrapped in rice, the ingredients can be seen when the product is made, which has the advantage of conveying visual appeal to consumers.

However, in products that combine cooked rice and ingredients, the ingredients need to be cut into small pieces, and there is a risk that the ingredients used will be limited to those that make this possible.

In addition, in products where ingredients are embedded in a recess, since the rice ball is round in shape, the recess shape is naturally basically round, and by embedding small ingredients or ingredients with an approximately circular shape, it is possible to achieve both external aesthetics.
However, when the ingredients are large or other than roughly circular in shape, the exterior of the rice ball is round and the depression is also round, making it difficult to visually balance the rice portion and the ingredients, and difficult to achieve a beautiful external appearance.

Furthermore, when the cooked rice block formed into a bowl shape is used as a container inside which ingredients are stored, a large storage space for the ingredients can be secured, and a highly aesthetic appearance can be obtained.
However, the above-mentioned molding containers are designed for home use, and require the application of heat for molding and have a large space for storing ingredients, making it difficult to hold the containers in the hand and eat them easily like rice balls.
Furthermore, when displaying the product, it is necessary to weld or attach a packaging sheet to the bottom of the cooked rice block using an adhesive such as tape so that the ingredients can be seen; however, since the cooked rice block is bowl-shaped, its complex shape may make it difficult to package the product when it is made into a product.

The present invention was made in consideration of these circumstances, and solves the above problem by storing ingredients in a rectangular space in the center of the interior and wrapping the entire product in a wrapping sheet.

To solve the above-mentioned problems, the square-shaped rice block is characterized by the fact that the ingredients are placed in a square space in the center and the whole is wrapped in a wrapping sheet.

In addition, in a packaging sheet structure that packages a packaging sheet for a square-shaped mass of rice containing ingredients in an openable manner, the packaging sheet body is composed of an upper side covering part that is folded over and overlapped with the underside of the square-shaped mass of rice via both sides from the top of the square-shaped mass of rice, and front and rear end covering parts that are made by folding the left and right side sheets at the front and rear end parts of the square-shaped mass of rice and folding over the undersides of the front and rear ends and welding them together.Furthermore, it is also characterized by the fact that a tearing band is welded and overlapped on the top surface of the packaging sheet body, a handle piece is extended from the tip of the band that extends from one side of the square-shaped mass of rice to the other side, and the packaging sheet body is torn from the handle piece via the band welded to the packaging sheet body to expose the square-shaped mass of rice together with the ingredients.

According to the present invention, the square-shaped rice block has ingredients stored in a square space in the center and the entire block wrapped in a packaging sheet, which ensures a large space for storing ingredients, and has the effect of making it possible to produce various types of products without being limited by the size or shape of the ingredients to be stored.

In addition, the rectangular shape of the storage space means that ingredients can be stored without being limited by their size or shape, which has the effect of creating a highly aesthetic appearance.

In addition, the square shape of the rice block reminds consumers of a lunch box, and depending on the ingredients stored inside, it can have a unique aesthetic appearance that makes it seem like a small, easy-to-eat lunch box, which has the effect of catching consumers' attention.

In addition, the rice chunks are square in shape, which makes it relatively easy to wrap them in a wrapping sheet, making it possible to package them automatically.

According to the present invention, a strip is welded to the packaging sheet body and a tab is extended from the tip of the strip, which has the effect that a consumer can easily tear and open the packaging sheet body along the strip by pulling the tab.

In addition, by wrapping the packaging sheet body from the top of the square rice lump, the consumer can visually check the contents, which has the effect of making it possible to wrap the square rice lump without interfering with its beautiful appearance.

In addition, by tearing the packaging sheet along the strip and opening it, it is possible to adjust the ratio of the square-shaped rice block and the ingredients exposed, and it is possible to appropriately select a shape that is easy to eat by widening the opening width to match the ingredients stored in the square-shaped rice block, and a configuration in which the remaining wrapping acts as a wall to prevent the ingredients from falling out.

The gist of this invention is that the ingredients are placed in a rectangular space in the center of a square-shaped block of rice, and the whole is wrapped in a wrapping sheet.

In addition, in a packaging sheet structure that packages a packaging sheet for a square-shaped mass of rice containing ingredients in an openable manner, the packaging sheet body is composed of an upper side covering part that is folded over and overlapped with the underside of the square-shaped mass of rice via both sides from the top of the square-shaped mass of rice, and front and rear end covering parts that are made by folding the left and right side sheets at the front and rear end parts of the square-shaped mass of rice and folding over the undersides of the front and rear ends and welding them together.Furthermore, it is also characterized by the fact that a tearing band is welded and overlapped on the top surface of the packaging sheet body, a handle piece is extended from the tip of the band that extends from one side of the square-shaped mass of rice to the other side, and the packaging sheet body is torn from the handle piece via the band welded to the packaging sheet body to expose the square-shaped mass of rice together with the ingredients.

[1. Structure of the square-shaped rice lump according to the present invention]
An embodiment of a square-shaped rice lump according to the present invention will be described in detail below with reference to the drawings.
Figures 1 to 3 are explanatory diagrams illustrating the square-shaped rice lump of the present invention, with Figure 1 being a schematic perspective view showing the overall image of the square-shaped rice lump, Figure 2 being a schematic perspective view showing the structure of the rice lump main body, and Figure 3 being a schematic explanatory diagram showing the specific dimensions of the square-shaped rice lump.

As shown in Figures 1 and 2, the square-shaped rice block 1 of the present invention is made by forming cooked rice into a square box shape, storing ingredients 2 in the square space S at the top, and packaging it in a packaging sheet 3 that is formed to be easily opened.

As shown in Figure 2, the square-shaped rice lump 1 is formed into a square box shape overall and is composed of a bottom 11 that is square in plan view, a front wall portion 12 that is square in front view and extends from one edge of the bottom 11, a rear wall portion 13 that faces the front wall portion 12 and has the same shape, a square right wall portion 14 that is interposed between the right edge of the front wall portion 12 and the left edge of the rear wall portion 13, and a left wall portion 15 that faces the right wall portion 14 and has the same shape.
The space at the upper opening formed by the bottom 11 and each of the walls 12 to 15 is a rectangular space S, which has the function of storing the ingredient 2 described later.

More specifically, as shown in FIG. 3, the width A of the front wall portion 12 and the rear wall portion 13 is 60 mm to 80 mm, the width B of the right wall portion 14 and the left wall portion 15 is 80 mm to 100 mm, the height C of each wall portion 12 to 15 is 30 mm to 40 mm, the thickness D of each wall portion 12 to 15 is 8 mm to 10 mm, and the height c of the bottom portion 11 is 10 mm to 20 mm.

When forming the square-shaped rice block 1, pressure is applied to the cooked rice placed in the mold so that it is firm enough to hold its shape when lifted by hand.

The square space S provided in the square rice block 1 can store ingredients 2 for a lunch box, such as grilled meat or minced chicken, so the square rice block 1 functions as a container for storing ingredients 2.

By using the square rice block 1 as a container to store the ingredients 2, the ingredients 2 and cooked rice can be eaten at the same time, making it easier to eat than a lunch box made of paper or plastic containers.
In addition, by storing the ingredients 2 in the rectangular space S, it is possible to arrange the ingredients in a delicate manner that was not possible with onigiri, which allows the ingredients 2 to be easily eaten together with rice.

Furthermore, the square-shaped rice block 1 functions as a container by being formed by pressure, so the square space S has a certain depth, and is dense enough to prevent leakage of small amounts of liquid, making it possible to store things that contain soup stock, such as the ingredients in a chicken and egg rice bowl.

In addition, the square-shaped rice block 1 is generally in the shape of a square box and has a square space S that is a square ingredient storage area, so it is possible to provide a large storage space for the ingredients 2, and there are fewer detailed restrictions on the type and size of the ingredients 2, making it easier to serve them.

As described above, the square-shaped rice block 1 is made by serving ingredients 2 in cooked rice formed into a square box shape, and unlike basic rice balls with ingredients, the ingredients 2 can be seen. Furthermore, the appearance of the square-shaped rice block 1 combined with the appearance of a bento box gives it a highly aesthetic appearance, which is eye-catching to consumers.

The square-shaped rice block 1 is said to mainly form cooked rice, but it is not limited to rice and may be other grains such as barley or foxtail millet, or may be cooked rice in which other ingredients are mixed into rice or multigrain rice in which other grains are cooked with rice.

[2. Configuration of the packaging sheet according to the present invention]
The packaging sheet according to the present invention will be described in detail below with reference to the drawings.
Fig. 4, Fig. 6 and Fig. 7 are explanatory diagrams showing the structure of the packaging sheet according to the present invention, Fig. 4 is an overall perspective view showing the structure of the packaging sheet according to the present invention, Fig. 6 is a schematic exploded perspective view showing the structure of the packaging sheet, Fig. 7 is a schematic perspective view showing the packaging sheet in an unsealed state, and Fig. 5 is a schematic perspective view showing the process of packaging with the packaging sheet.

As shown in FIG. 1, the packaging sheet 3 is composed of an upper side covering portion 41 that is folded over and overlapped on the underside of the square-shaped rice lump 1 from the top surface of the square-shaped rice lump 1 through both side surfaces, i.e., the left and right wall portions 14, 15, and front and rear end covering portions 42 that are formed by folding over the left and right side sheets 421 at the front and rear end surfaces of the square-shaped rice lump 1 , i.e., the front and rear wall portions 12, 13, and folding over the undersides of the front and rear ends to weld them together.

As shown in FIG. 4, the packaging sheet 3 is a rectangular sheet member made of a transparent resin film.

As shown in FIG. 5, the packaging sheet 3 wraps the entire square-shaped rice block 1 from the top, and the four edges of the packaging sheet 3 overlap and are welded together under the square-shaped rice block 1 to package it.

The upper side covering portion 41 refers to the overlapping portion that is formed by folding back from the top surface of the square-shaped rice block 1 through the left and right wall portions 14, 15 to the bottom surface and overlapping with the square-shaped rice block 1, and the contact surface with the square-shaped rice block 1. The upper side covering portion 41 allows the top surface of the square-shaped rice block 1, i.e., the surface where the ingredients 2 stored in the square space portion S can be seen, and the left and right wall portions 14, 15 to be covered with the packaging sheet 3.
At this time, the underside of the rectangular rice block 1 is in a state where two surfaces, the surface folded back via the right wall portion 14 and the surface folded back via the left wall portion 15, overlap each other.

The front and rear end wrapping parts 42 refer to the parts of the packaging sheet 3 other than the above-mentioned upper surface wrapping part 41, and by folding back and overlapping from the top surface of the square-shaped rice block 1 to the bottom surface via the front and rear wall parts 12, 13, together with the upper surface wrapping part 41, the entire surface of the square-shaped rice block 1 can be covered.

Therefore, the packaging sheet 3 covers the top surface and left and right wall portions 14, 15 of the square-shaped rice block 1 with the upper side covering portion 41, and covers the front and rear wall portions 12, 13 of the square-shaped rice block 1 with the front and rear end covering portions 42.
In addition, the underside of the square-shaped rice block 1 can be covered by folding back and overlapping the upper surface covering portion 41 and the front and rear end covering portions 42.

As a specific procedure for packaging the above-mentioned package, first, as shown in FIG. 5(a), a package sheet 3 is placed over the square-shaped rice lump 1.
The next step is to fold the packaging sheet 3 downward so as to fit along the left and right walls 14, 15 of the rectangular rice lump 1, as shown in FIG. 5(b).

In this case, the packaging sheet 3 has a U-shaped cross section, and the portion in contact with the top surface of the square-shaped rice block 1, the portion in contact with the left and right wall portions 14, 15 of the square-shaped rice block 1, and the portion extending downward and hanging down from the portion in contact with the left and right wall portions 14, 15 form the upper surface covering portion 41, and the other portions form the front and rear end covering portions 42.
In other words, the front and rear end covering portions 42 are portions that extend to the front and rear of the square-shaped rice block 1 in Figure 5 (b) and have a U-shaped cross section.

The next step is to fold the entire front and rear end covering portions 42 downward while folding the left and right side sheets 421 toward the inside of the U-shape, that is, toward the center of the front and rear walls 1 2 , 1 3 , as shown in FIG. 5( c ).
The above-mentioned left and right side sheets 421 refer to the portions of the upper surface covering portion 41 that contact the left and right wall portions 14, 15 and extend in the front-rear direction.

The final step is to fold back the portion of the upper surface wrapping portion 41 that extends downward from the portion where it contacts the left and right wall portions 14, 15, and the portion of the front and rear end wrapping portion 42 that extends downward from the portion where it contacts the front and rear wall portions 12, 13, toward the underside of the square-shaped block of rice 1, and then overlap and weld all of them together to create the packaging shape described above, as shown in Figure 5 (d).

As shown in Figs. 4 and 6, the packaging sheet 3 is composed of a rectangular sheet body 31 made of resin film, a tear strip 32 welded to the back side of the sheet body 31, i.e., the side that comes into contact with the rectangular rice block 1 during packaging, a U-shaped cut line 33 that crosses the tear strip 32 and is formed integrally with the sheet body 31, and a tab 34 that is attached to the surface of the sheet body 31 over the U-shaped cut line 33.

The sheet body 31 is formed from a rectangular transparent resin film.
The resin film used is a film that is highly transparent and easy to tear, such as a biaxially oriented polypropylene film.

The tear strip 32 is formed of a strip-shaped transparent resin film, for example, made of the same material as the sheet body 31 .
In addition, the tear strip 32 is integrated with the sheet body 31 by being heat-sealed to the back side of the sheet body 31, i.e., the side that comes into contact with the square-shaped rice block 1 during packaging.

In the embodiment, only the two edges of the strip are heat-sealed, but as long as the sheet body 31 and the tear strip 32 are integrated, the entire strip may be heat-sealed.

The tear strip 32 functions as a guide when tearing the sheet body 31 starting from the U-shaped cut line 33 described below, and has the effect of allowing the sheet body 31 to be torn into strips.

The U-shaped cut line 33 consists of a cross section 331 consisting of a cut or small hole formed to cross the middle of the tear strip 32 that is integrally welded to the sheet body 31, and a tear guide section 332 consisting of a cut or small hole formed perpendicular to both ends of the cross section 331 in the same direction, i.e., to form a U-shape together with the cross section 331.

Although both the sheet body 31 and the tear strip 32 are made of resin film that is easy to tear, the film cannot be easily torn by pulling on the edge, and a cut is required to start tearing.

The above-mentioned U-shaped cut line 33 is formed as a starting point for tearing the sheet body 31 .
That is, by tearing the transverse portion 331 of the U-shaped cut line 33 and pulling it toward the tear guide portion 332, the film is torn in a U-shape, and the sheet body 31 is torn starting from this U-shaped tear.

The tab 34 is made of a rectangular sticker or tape having an adhesive surface on one side, and is attached to the front side of the sheet body 31 so as to cover the U-shaped cut line 33.
That is, the U-shaped cut line 33 forms the tip of the tear strip 32, and the tab 34 is attached so as to extend from the tip.
By doing so, when the tab 34 is peeled off from the sheet body 31, the U-shaped cut line 33 breaks, and the sheet body 31 can be torn along the tear strip 32 by pinching and pulling the tab 34.

The tab 34 is not limited to a rectangular shape, and may be of any shape as long as it can cover the U-shaped cutout line 33 .
Also, although the entire side may be an adhesive surface, it is also conceivable to provide a non-adhesive portion to make opening even easier.
In addition, the tab 34 does not necessarily have to be a separate member from the sheet body 31. For example, a cut line may be provided in the outermost sheet of the front and rear wall portions 12, 13 into which the left and right side sheets 421 are folded, i.e., the sheet body 31 may be shaped to extend from the tip portion of the tear strip 32.

As shown in Figures 1 and 7, the tear strip 32 is welded to the sheet body 31 so as to run vertically or horizontally across the top surface of the square-shaped rice block 1 when packaged, and the gripping piece 34 is packaged so as to be positioned on either the front and rear walls 12, 13 or the left and right walls 14, 15.

When opening the package, as described above, the tab 34 is used as an opening, the U-shaped cut line 33 is broken, and the sheet body 31 is torn along the tear strip 32 .
In this embodiment, the width of the tear strip 32 is set to be the same as the width of the rectangular space S, so that the upper surface of the rectangular block of rice 1 together with the ingredients 2 stored in the rectangular space S can be widely exposed, as shown in FIG. 7 .

When eating, there are two possible methods: eating from the exposed top part of the square rice block 1 using chopsticks, or rolling up either the front and rear walls 12, 13 or the left and right walls 14, 15 of the square rice block 1 downward and eating it directly like a rice ball.

As described above, the square-shaped rice block 1 contains the ingredients 2 in the square space S. When eaten directly like a rice ball, the ingredients 2 are supported by the walls 12 to 15, so that even if the block is tilted slightly, it can be eaten without spilling out.

The packaging sheet 3 has all four edges welded together on the underside of the square rice block 1, and combined with the transparency of the sheet body 31, the square rice block 1 topped with ingredients 2 can be seen in its packaged state. This is expected to visually stimulate consumers' desire to buy when displayed in convenience stores, supermarkets, etc., without compromising its aesthetic appearance.

[3. Other embodiments]
Another embodiment of the square-shaped rice lump according to the present invention will be described in detail below with reference to the drawings.
Figures 8 to 13 are schematic perspective views showing other embodiments of a square-shaped rice block. Figures 8 to 10 are explanatory views showing other embodiments relating to a tear strip provided on a packaging sheet. Figures 11 and 12 are explanatory views showing a state in which an infiltration prevention sheet is provided between a square-shaped rice block and ingredients. Figure 13 is a schematic perspective view showing another embodiment relating to the shape of a square-shaped rice block.

Another embodiment of the square-shaped rice block 1 according to the present invention is one in which the width of the tear strip 32 provided on the packaging sheet 3 is narrowed, as shown in FIG. 8.

In this embodiment, the exposed portion of the upper surface of the square-shaped rice block 1 can be reduced when opened.
In other words, it is possible to increase the area covered by the packaging sheet 3 when the package is opened.
With this configuration, when the product is eaten directly like a rice ball, the ingredients are protected by the packaging sheet 3, making it possible to eat the product more hygienically when time is required for eating, and also making it possible to better prevent the ingredients 2 from spilling out.

As another example, as shown in FIG. 9, it is possible to provide a tear strip 32 that crosses the square-shaped rice block 1.

In the embodiment described above, a tear strip 32 is formed to cut the rectangular rice block 1 vertically, i.e., to separate the opposing long sides on the top surface of the rectangular rice block 1 as viewed in the drawing.
This allows the shorter side to be exposed on the top surface of the square-shaped rice block 1 when opened, which has the effect of improving handling and ease of eating when eating with one hand.

As another example, as shown in Figure 10, it is possible to narrow the width of the tear strip 32 and weld it to one of the walls 12 to 15 of the square-shaped rice block 1.

In this embodiment, a smaller area can be exposed when opened, and the portion of the packaging sheet 3 that remains when the package is eaten immediately, such as in the case of a rice ball, functions to ensure hygiene and protect the ingredients 2 as in the embodiment shown in Figure 7, while also providing an effect of making it easier to eat as the area that can be handled is wider.
In addition, when the sheet body 31 is torn by the tear strip 32, the area of the remaining packaging sheet 3 that covers the upper surface of the square-shaped rice lump 1 on one side can be narrowed, which has the effect of making it easier to roll the sheet 3 onto the lower surface of the square-shaped rice lump 1 without it getting caught on the square-shaped rice lump 1.

Another possible embodiment is one in which a moisture-preventing sheet 5 is provided between a square-shaped block of rice 1 and ingredients 2, as shown in Figures 11 and 12.

The infiltration prevention sheet 5 is a rectangular sheet member formed from a transparent resin film such as a biaxially oriented polypropylene film, the same as the sheet body 31 of the packaging sheet 3.

The moisture prevention sheet 5 is made of a resin film and does not absorb moisture. Therefore, by providing the sheet between the square-shaped rice block 1 and the ingredients 2, the sheet can receive moisture from the ingredients 2, for example, broth when the ingredients 2 are used as ingredients for an oyakodon (chicken and egg rice bowl), and prevent the moisture from seeping into the square-shaped rice block 1.
This has the effect of preventing the square-shaped rice lump 1 from becoming brittle due to the incorporation of moisture.

The moisture-preventing sheet 5 may be simply inserted between the square-shaped rice block 1 and the ingredients 2, and after opening, the moisture-preventing sheet 5 may be pulled out laterally before eating, or one side may be welded to the packaging sheet 3, and when the packaging sheet 3 is torn and rolled up to eat, the sheet is pulled along with the rice block 1 to assist in pulling out the moisture-preventing sheet 5.

When the packaging sheet 3 and the moisture-preventing sheet 5 are welded together, the moisture-preventing sheet 5 will not come apart, which is expected to make it easier to collect trash when eating outdoors.

In another embodiment, as shown in Figure 13, a square-shaped rice block 1 has a plurality of square spaces S, making it possible to store two or more types of ingredients 2 in the first storage space S1 and the second storage space S2.
In other words, a plurality of ingredients 2 can be stored in the square-shaped rice block 1, and the plurality of flavors can be prevented from mixing.
Furthermore, not only can two or more flavors be enjoyed from one square-shaped rice lump 1, but the rice can be presented in a wider variety of ways, and the square-shaped rice lump 1 can have a unique and highly aesthetic appearance.

In addition, in the drawings, two storage spaces S1 and S2 are shown to be of the same size, but this is not limited to this, and three or four rectangular spaces S may be provided as necessary, and large and small spaces may be mixed.
This makes it possible to arrange the food in a way that stores multiple ingredients 2, for example in a makunouchi bento box, and allows for a balanced meal presentation, with a large space for storing the main dish and a small space for storing the side dish.

The various effects described above are merely a list of the most favorable effects resulting from the present invention, and the effects of the present invention are not limited to those described in this embodiment.
