Description

There is an application for the application of Article 30, Paragraph 2 of the Patent Law Exhibited and released at the Delicatessen Trade Show 2021 from February 17, 2021 to February 19, 2021. [Publications, etc.] From December 3, 2020, an introductory video was posted on a video posting site and released.

TECHNICAL FIELD The present invention relates to a square-shaped rice block in which ingredients are housed in a square space at the center of the interior and the whole is wrapped with a packaging sheet.

2. Description of the Related Art Conventionally, there are various products in convenience stores, supermarkets, etc., in which a lump of boiled rice containing ingredients is wrapped with a wrapping sheet. For example, there are rice balls in which cooked rice is formed in a substantially triangular shape, rice balls in which cooked rice is formed in a substantially round shape, and the like.

However, most rice balls currently on the market are made by wrapping the ingredients inside, making it impossible to see the ingredients inside from the outside. I often chose a product.

On the other hand, there are products that can be distinguished by visually recognizing the difference in taste even through the packaging sheet.
For example, products such as takikomi gohan (takikomi gohan) and mixed gohan (rice mixed with ingredients) mixed with rice and ingredients, or products in which ingredients are embedded in a round-shaped rice ball with a slight depression in the approximate center. There are various forms.

On the other hand, there is a molded container for the purpose of serving ingredients in a bowl-shaped lump of boiled rice, which is formed so that the shape can be maintained by putting boiled rice into the container and heating it.

As described above, if the ingredients are exposed without being wrapped in boiled rice, the ingredients can be visually recognized when made into a product, and there is an advantage that the appeal can be visually conveyed to consumers.

However, in a product in which cooked rice and ingredients are mixed, it is necessary to reduce the size of the ingredients, and there is a risk that the ingredients are limited to those that allow this.

In addition, in products where ingredients are embedded in the hollow, the round shape of the rice ball is used, so the shape of the hollow is naturally round. be able to.
However, when the ingredients are large or not nearly circular, the appearance of the rice ball is round and the dents are also round, so it is difficult to visually balance the rice and the ingredients. It is difficult to obtain a beautiful appearance.

In addition, when ingredients are stored inside a bowl-shaped lump of boiled rice, a large storage space for the ingredients is secured, and a high external appearance can be obtained.
However, the above-mentioned molded container is assumed to be used at home, and it needs to be heated for molding and has a large storage space for ingredients, so it can be easily eaten by holding it in your hand like a rice ball. I didn't.
Furthermore, when displaying the product as a product, it is necessary to adhere the packaging sheet to the bottom of the rice mass by welding or using an adhesive such as tape in order to make the ingredients visible. Therefore, the shape is complicated, and there is a possibility that it may not be easy to package the product.

The present invention has been made in view of such circumstances, and has solved the above-mentioned problems by storing ingredients in a rectangular space at the center of the interior and wrapping the whole with a packaging sheet.

In order to solve the above conventional problems, the square-shaped rice mass is characterized in that ingredients are contained in a square space in the center of the interior and the whole is wrapped with a packaging sheet.

In addition, in the packaging sheet structure in which the packaging sheet of the square-shaped rice lump containing the ingredients is unsealably wrapped, the packaging sheet main body is folded back from the upper surface of the square-shaped rice lump through both sides at the lower surface of the square-shaped rice lump. and a front and rear end covering portion formed by folding the left and right side sheets at the front and rear end surfaces of the square-shaped rice loaf, folding the lower surfaces of the front and rear ends, and integrally welding the lower surfaces of the front and rear ends. A strip for tearing is welded and overlapped on the upper surface of the sheet body, and a tab piece is extended to the tip of the strip extending from one side to the other side of the square-shaped rice block, and the strip welded to the packaging sheet body is interposed. It is also characterized in that the package sheet body is torn from the tab piece and the square-shaped rice lump is exposed together with the ingredients.

According to the first aspect of the invention, the square-shaped rice mass accommodates the ingredients in the square space at the center of the interior and is wrapped with the packaging sheet, so that a wide space for accommodating the ingredients can be secured. This has the effect of making it possible to manufacture various types of products without being limited to the size and shape of the ingredients to be stored.

In addition, since the storage space has a rectangular shape, it is possible to arrange the ingredients to be stored without being limited to the size and shape thereof, and there is an effect that a high external appearance can be obtained.

In addition, by making the shape of the lump of rice square, consumers are reminded of a boxed lunch container, and depending on the ingredients to be stored, it is possible to present a unique aesthetic appearance of a boxed lunch that is small and can be eaten easily. It has the effect of attracting the attention of consumers.

In addition, since the lump of rice has a square shape, the shape is relatively easy to package with a packaging sheet, and there is an effect that automatic packaging is possible.

According to the second aspect of the present invention, the band welded to the packaging sheet body and the tab piece extending from the leading end of the band member allow the consumer to wrap along the band by pulling the tab piece. There is an effect that the sheet body can be easily torn open.

In addition, by packaging the main body of the packaging sheet from the upper surface of the square-shaped rice lump, the contents can be visually recognized by the consumer. be.

In addition, by tearing and opening the packaging sheet along the strip, it is possible to adjust the exposed ratio of the square-shaped rice lump and the ingredients. There is an effect that it is possible to appropriately select a shape that is wide and easy to eat and a structure that uses the remaining foreskin as a wall to prevent the ingredients from falling.

The gist of the present invention is that in a square-shaped rice block, ingredients are contained in a square space at the center of the interior and the whole is wrapped with a packaging sheet.

In addition, in the packaging sheet structure in which the packaging sheet of the square-shaped rice lump containing the ingredients is unsealably wrapped, the packaging sheet main body is folded back from the upper surface of the square-shaped rice lump through both sides at the lower surface of the square-shaped rice lump. and a front and rear end covering portion formed by folding the left and right side sheets at the front and rear end surfaces of the square-shaped rice loaf, folding the lower surfaces of the front and rear ends, and integrally welding the lower surfaces of the front and rear ends. A strip for tearing is welded and overlapped on the upper surface of the sheet body, and a tab piece is extended to the tip of the strip extending from one side to the other side of the square-shaped rice block, and the strip welded to the packaging sheet body is interposed. It is also characterized in that the package sheet body is torn from the tab piece and the square-shaped rice lump is exposed together with the ingredients.

[1. Regarding the configuration of the square-shaped rice mass according to the present invention]
Hereinafter, embodiments of the square-shaped rice lump according to the present invention will be described in detail based on the drawings.
1 to 3 are explanatory diagrams for explaining the square-shaped rice lump of the present invention. FIG. 1 is a schematic perspective view showing the overall image of the square-shaped rice lump, and FIG. 2 is a schematic diagram showing the structure of the main body of the rice lump. FIG. 3 is a schematic perspective view showing specific dimensions of the rectangular rice lump.

As shown in FIGS. 1 and 2, the square-shaped rice mass 1 according to the present invention is formed mainly of cooked rice in a square box shape, and the ingredients 2 are stored in the square space S provided at the top. Furthermore, it is packaged with a package sheet 3 that is formed to be openable.

As shown in FIG. 2, the square-shaped rice mass 1 is formed in the shape of a square box as a whole. , a rear wall portion 13 having the same shape facing the front wall portion 12, a square right wall portion 14 interposed between the right edge of the front wall portion 12 and the left edge of the rear wall portion 13, and the right wall portion. 14 and a left wall portion 15 having the same shape.
Further, the space of the upper opening formed by the bottom portion 11 and the wall portions 12 to 15 is defined as a rectangular space portion S, which has a function of storing the ingredients 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, and each wall portion The height C of 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 mass 1, pressure is applied to the cooked rice placed in the mold so that it has a hardness that does not lose its shape when lifted by hand.

The square space S provided in the square-shaped rice block 1 can accommodate the ingredients 2 of lunch boxes such as grilled meat and minced chicken.

By using the square-shaped rice block 1 as a container to store the ingredient 2, the ingredient 2 and the cooked rice can be eaten at the same time, and can be eaten more easily than a boxed lunch made of a paper or plastic container.
In addition, by storing the ingredients 2 in the rectangular space S, it is possible to delicately arrange the ingredients, which could not be achieved with rice balls in which the ingredients 2 and cooked rice can be easily eaten.

Furthermore, since the square-shaped rice mass 1 functions as a container by being formed by pressure, it has a certain depth in the square space S and does not leak if it is a high-density liquid with a certain amount of liquid. For example, it is possible to store items containing soup stock such as ingredients for oyakodon.

In addition, since the square-shaped rice mass 1 has a square box shape as a whole and has a square space S that is a square-shaped ingredient storage section, a wide storage space for the ingredients 2 can be provided. There is little restriction on the type, size, etc. of the ingredients 2, and there is an effect of facilitating serving.

As described above, in the square-shaped rice ball 1, the ingredients 2 are served in a container made of cooked rice formed in a rectangular box shape. Combined with the appearance of the shaped rice lump 1, it has an appearance like a bento box, so that a high aesthetic appearance can be obtained, and an effect of attracting consumers' attention can be exhibited.

Although it is said that the square-shaped rice mass 1 mainly forms cooked rice, it is not limited to rice, and other grains such as barley and millet may be used. It is also possible to use mixed grain rice cooked with rice.

[2. Regarding the configuration of the packaging sheet according to the present invention]
Hereinafter, the packaging sheet according to the present invention will be described in detail with reference to the drawings.
4, 6 and 7 are explanatory diagrams showing the configuration of the packaging sheet according to the present invention, FIG. 4 is an overall perspective view showing the configuration of the packaging sheet according to the present invention, and FIG. 6 is the configuration of the packaging sheet. FIG. 7 is a schematic perspective view showing an unsealed state of the packaging sheet. Moreover, 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 an upper side covering portion that overlaps the lower surface of the rectangular rice lump 1 by folding back from the upper surface to both side surfaces of the rectangular rice lump 1 via the left and right walls 14 and 15. 41, and front and rear end covering portions 42 formed by folding the left and right side sheets 422 in the front and rear end surfaces of the rectangular rice mass 1, that is, the front and rear wall portions 12 and 13, folding back the lower surfaces of the front and rear ends, and integrally welding them. ing.

The packaging sheet 3, as shown in FIG. 4, is a rectangular sheet member and is formed of a transparent resin film.

As shown in FIG. 5, the packaging sheet 3 wraps the entire square-shaped rice lump 1 from the upper surface, overlaps the four edges of the packaging sheet 3 on the lower surface of the square-shaped rice lump 1, and is integrally welded. ing.

The upper side surface covering portion 41 refers to the contact surface of the square-shaped rice lump 1 and the overlapping portion that is folded back and overlapped on the lower surface from the upper surface of the square-shaped rice lump 1 via the left and right walls 14 and 15, and the upper surface. The covering portion 41 allows the wrapping sheet 3 to cover the upper surface of the rectangular rice mass 1 , that is, the surface where the ingredients 2 stored in the rectangular space S can be seen, and the left and right walls 14 and 15 .
At this time, the lower surface of the square-shaped rice block 1 is in a state in which two surfaces, that is, the surface folded back via the right wall portion 14 and the surface folded back the left wall portion 15 overlap each other.

The front and rear end covering portions 42 refer to portions of the packaging sheet 3 other than the upper side covering portion 41 described above, and are folded back from the upper surface of the square-shaped rice loaf 1 to the lower surface via the front and rear wall portions 12 and 13 to overlap. Thus, the entire surface of the rectangular rice lump 1 can be covered together with the upper side covering portion 41 .

Therefore, the packaging sheet 3 covers the upper surface and the left and right walls 14 and 15 of the rectangular rice lump 1 with the upper side surface covering portion 41 , and the front and rear wall portions 12 of the rectangular rice lump 1 with the front and rear end covering portions 42 . , 13.
In addition, the lower surface of the square-shaped rice block 1 can be covered by folding the upper surface covering portion 41 and the front and rear end covering portions 42 so as to overlap each other.

As a specific packaging procedure for realizing the packaging form described above, first, as shown in FIG.
As the next procedure, as shown in FIG. 5(b), the packaging sheet 3 is folded downward along the left and right walls 14 and 15 of the rectangular rice lump 1. Then, as shown in FIG.

At this time, the packaging sheet 3 has a U-shaped cross section, a portion in contact with the upper surface of the rectangular rice block 1, a portion in contact with the left and right walls 14 and 15 of the rectangular rice block 1, The portion that extends downward from the portion in contact with the left and right walls 14 and 15 and hangs down forms the upper side surface covering portion 41 , and the other portion forms the front and rear end portion covering portions 42 .
That is, the front and rear end covering portions 42 are portions extending forward and backward of the rectangular rice lump 1 shown in FIG.

As the next procedure, as shown in FIG. 5C, the left and right side sheets 421 are folded toward the inside of the U-shape, that is, toward the center of the front and rear walls 14 and 15, and the entire front and rear end covering portions 42 are folded. fold down.
The left and right side sheets 421 described above refer to the portions of the upper side covering portion 41 that are in contact with the left and right walls 14 and 15 and extend in the front-rear direction.

As a final procedure, the portion extending downward from the portion of the upper side surface covering portion 41 in contact with the left and right walls 14 and 15 and hanging down, and the front and rear wall portions 12 and 13 of the front and rear end portion covering portion 42 are attached. The part that extends downward from the contact part and hangs down is folded back toward the lower surface of the square-shaped rice lump 1, and all are overlap-welded to achieve the above packaging form as shown in FIG. 5(d). can do.

More specifically, the structure of the packaging sheet 3 is, as shown in FIGS. 4 and 6, a sheet main body 31 made of a rectangular resin film and a back surface of the sheet main body 31, that is, the side that comes into contact with the rectangular rice mass 1 during packaging. a U-shaped drilled wire 33 formed integrally with the sheet body 31 across the tear strip 32, and the U-shaped drilled wire 33 pasted on the surface of the sheet body 31 and a gripping piece 34 attached thereto.

The sheet body 31 is formed from a rectangular transparent resin film.
For this resin film, a film such as a biaxially stretched polypropylene film, which has high transparency and is easy to tear, is used.

The tear strip 32 is made of a strip-shaped transparent resin film, for example, the same material as the sheet body 31 .
The tear band 32 is integrated with the sheet body 31 by heat-sealing it to the back side of the sheet body 31, that is, the side that comes into contact with the square-shaped rice lump 1 during packaging.

In the embodiment, only the two edges of the band are welded to the heat-welding surface, but the sheet body 31 and the tear band 32 may be heat-welded as long as they are integrated.

The tear band 32 functions as a guide when tearing the sheet body 31 starting from a U-shaped tear line 33, which will be described later, and has the effect of tearing the sheet body 31 into a strip.

The U-shaped drilled wire 33 is formed in the same direction from both ends of the crossing portion 331, which is a cut or a small hole formed so as to cross the middle portion of the tear band 32 welded integrally with the sheet body 31. , i.e., a tear guide portion 332 consisting of a notch or a small hole formed so as to form a U-shape together with the transverse portion 331 .

Although both the sheet body 31 and the tear band 32 are made of an easily tearable resin film, they are not easily torn even when the edges of the film are pulled, and a cut as a starting point is required for tearing.

The U-shaped cut line 33 described above is formed as a starting point for tearing the sheet body 31 .
That is, by tearing the crossing portion 331 of the U-shaped drilled wire 33 and pulling it toward the tear guide portion 332, the film is torn in a U-shape, and the sheet body 31 is pulled starting from the U-shaped tear. configured to tear.

The tab piece 34 is made of a rectangular sticker, tape, or the like having an adhesive surface on one side, and is attached to the surface side of the sheet body 31 so as to cover the U-shaped drilled wire 33 .
That is, the U-shaped drilled wire 33 becomes the leading end of the tear strip 32, and the grip piece 34 is attached so as to extend the leading end.
By doing so, when the tab piece 34 is peeled off from the sheet body 31, the U-shaped slit wire 33 is broken, and by pinching and pulling the tab piece 34, the sheet body 31 can be torn along the tear band 32.例文帳に追加.

The grip piece 34 is not limited to a rectangular shape, and may be of any shape as long as it can cover the U-shaped drilled wire 33 .
Moreover, although one side may be entirely adhered, it is also conceivable to provide a partially non-adhered portion to facilitate opening.
Further, the grip piece 34 does not necessarily have to be a separate member from the sheet body 31. For example, the sheet of the front and rear walls 12 and 13, in which the left and right side sheets 422 are folded, is provided with a slit line on the outermost layer of the sheet. may be extended from the tip portion of the tear band 32 .

As shown in FIGS. 1 and 7, the tear band 32 is welded to the sheet body 31 so as to extend vertically or across the upper surface of the rectangular rice lump 1 when wrapped, and the tab pieces 34 are attached to the front and rear wall portions 12, 12 and 12 respectively. 13 or left and right wall portions 14 and 15.

When opening, as described above, the tab 34 is used as an opening, and the U-shaped slit wire 33 is broken, and the sheet body 31 is torn along the tear strip 32 .
In this embodiment, the width of the tear band 32 is the same as the width of the rectangular space S. Therefore, as shown in FIG. The upper surface can be exposed widely.

When eating, either the front and rear walls 12 and 13 or the left and right walls 14 and 15 are rolled up below the square-shaped rice lump 1. , the method of eating directly like rice balls is conceivable.

As described above, the square-shaped rice mass 1 contains the ingredients 2 in the square space S, so that the ingredients 2 are supported by the walls 12 to 15 when directly eaten like rice balls. There is an effect that it becomes possible to eat without spilling even if it is slightly tilted.

The packaging sheet 3 has four edges integrally welded to the lower surface of the square-shaped rice block 1, and combined with the transparency of the sheet body 31, the appearance of the square-shaped rice block 1 on which the ingredients 2 are served can be visually recognized in the packaged state. For example, when displayed in convenience stores, supermarkets, etc., it can be expected to have the effect of visually stimulating consumers' willingness to purchase without impairing the high aesthetic appearance.

[3. Regarding other embodiments]
Hereinafter, another embodiment of the square-shaped rice lump according to the present invention will be described in detail with reference to the drawings.
8 to 13 are schematic perspective views showing other examples of rectangular rice lumps. 8 to 10 are explanatory diagrams showing another embodiment of the tear band provided on the packaging sheet. 11 and 12 are explanatory diagrams showing a state in which a permeation prevention sheet is provided between the square-shaped rice block and ingredients. FIG. 13 is a schematic perspective view showing another embodiment regarding the shape of the square-shaped rice lump.

As another embodiment of the square-shaped rice loaf 1 according to the present invention, as shown in FIG.

In this embodiment, it is possible to narrowly expose the upper surface portion of the square-shaped rice lump 1 when the package is opened.
In other words, it is possible to increase the portion covered with the packaging sheet 3 at the time of opening.
By adopting such a structure, when eating directly like a rice ball, the ingredients are protected by the packaging sheet 3 and can be eaten more hygienically when it takes time to eat, and the ingredients 2 are prevented from spilling. There is an effect that it is possible to further prevent
