Summary of the Invention

Problems to be Solved by the Invention

[0004] For rice such as polished rice, where the rice grains are bound to each other with a certain degree of binding force, the rice grains can be eaten as a nori-wrapped rice ball without spilling. However, in the case of rice composed of rice grains with oil adhering to the surface, such as fried rice or cooked rice, the binding force between the rice grains may be weak, and even if it is solidified like a rice ball, it may be difficult to eat because the shape collapses and the rice grains spill when eating.

[0005] An object of the present invention is to provide a rice packaging body and rice-packaged food that can be eaten without spilling the rice regardless of the binding force between the rice grains.

Means for Solving the Problems

[0006] The rice packaging body of the present invention comprises a film body formed from a film material into a triangular bag shape, having a discharge port at its top and a rice storage port on the side opposite to the discharge port; more specifically, a first film body formed from a film material into a triangular bag shape, having a discharge port at its top and a rice storage port on the side opposite to the discharge port; and a second film body formed from a film material into a triangular bag shape, provided on the outside of the first film body so as to enclose at least the discharge port of the first film body, with the tip portion corresponding to the discharge port being sealed and the bottom portion corresponding to the rice storage port being open.

[0007] The rice-packaged food of the present invention comprises the above-described rice packaging body containing rice. [Effects of the Invention]

[0008] According to the present invention, it is possible to provide a rice packaging and rice packaging food that allows rice to be eaten without spilling, regardless of the binding force between rice grains. [Brief explanation of the drawing]

[Figure 3] This is a plan view showing a rice package containing rice according to the embodiment, resulting in a packaged rice food product. [Figure 4] This is a diagram illustrating the usage state of a packaged rice food product according to an embodiment. [Figure 5] This is a plan view showing a modified rice packaging body according to an embodiment. [Modes for carrying out the invention]

[0010] Embodiments of the present invention will be described below. As shown in Figure 1, the rice packaging body 1 has a first film body 10 and a second film body 20. The first film body 10 contains rice, and the second film body 20 is a component that packages the first film body 10. The first film body 10 and the second film body 20 are each formed into a substantially triangular bag shape from a film material. In this embodiment, the film material of the first film body 10 is made of a resin material containing polyethylene (PE). In this embodiment, the film material of the second film body 20 is made of a resin material containing polypropylene (PP).

[0011] The first film body 10 is formed into a bag shape by, for example, folding a single film sheet into a triangular shape and welding the edges of the film sheet together. An outlet 11 is provided at the top of the roughly triangular shape of the first film body 10. The outlet 11 is open. The leading edge of the outlet 11 is formed in a roughly straight line along the horizontal HL direction (hereinafter also referred to as the "left-right direction") which is perpendicular to the perpendicular VL direction (hereinafter also referred to as the "up-down direction") from the top to the base of the roughly triangular shape of the first film body 10. A rice container opening 12 is provided on the side (base) of the roughly triangular shape of the first film body 10 that is opposite the outlet 11 in the up-down direction. The rice container opening 12 is open. That is, the first film body 10 is sealed except for the outlet 11 and the rice container opening 12. The edge of the rice container opening 12 is formed in a roughly straight line along the left-right direction. Specifically, the first film body 10 is formed in a roughly trapezoidal shape. The angle θ between the left and right inclined edges of the first film body 10 is set to approximately 34 degrees.

[0012] The second film body 20 is formed into a bag shape by joining the edges of two film sheets, for example, two films punched out in a roughly triangular shape, by welding or other means. The top of the roughly triangular shape of the second film body 20 is the tip portion 21, and the side opposite the tip portion 21 in the vertical direction is provided with a base portion 22. The edges of the tip portion 21 and the base portion 22 are formed in a roughly straight line along the left-right direction. The edges of the second film body 20 corresponding to the tip portion 21 in the vertical direction (left and right edges) are provided with a first straight edge portion 23a in the vertical direction. The edges of the second film body 20 corresponding to the base portion 22 in the vertical direction (left and right edges) are provided with a second straight edge portion 23c in the vertical direction. The second film body 20 is also provided with an inclined edge portion 23b that connects the first straight edge portion 23a and the second straight edge portion 23c. The portion where the second straight edge 23c and the inclined edge 23b connect is designated as the connecting edge 23d.

[0013] The leading edge 21 of the second film body 20 is sealed. In this embodiment, the two films at the leading edge 21 are welded and sealed by a welding portion 21a provided linearly in the left-right direction on the leading edge 21. On the other hand, the bottom edge 22 of the second film body 20 is open. That is, the second film body 20 is sealed except for the bottom edge 22. The edges where the bottom edge 22 opens are offset between the two films. For example, as shown in Figure 1, if the film sheet provided on the near side in the direction perpendicular to the plane of the paper in Figure 1 is the front sheet 20a and the film sheet provided on the far side is the back sheet 20b, then the edge of the bottom edge 22 of the front sheet 20a is located closer to the leading edge 21 than the edge of the back sheet 20b. This makes it easier to separate the front sheet 20a and the back sheet 20b when inserting the first film body 10 into the second film body 20 through the opening in the bottom edge 22.

[0014] The front sheet 20a of the second film body 20 is provided with a strip-shaped opening tab 24. The opening tab 24 is formed in a straight strip shape from the front end 21 to the bottom end 22 of the second film body 20. In this embodiment, when the tab 24a on the front end 21 side is grasped and the opening tab 24 is pulled down towards the bottom end 22, the front sheet 20a of the second film body 20 is split. In other words, the opening tab 24 is provided so that the second film body 20 can be split. The opening tab 24 is provided in a straight line from the front end 21 to an intermediate position on the way to the bottom end 22 of the second film body 20.

[0015] The second film body 20 is provided on the outside of the first film body 10 such that it encloses at least the discharge port 11 of the first film body 10. In this embodiment, approximately two-thirds of the first film body 10, including the discharge port 11, is enclosed within the second film body 20. The portion of the first film body 10 on the side of the food container opening 12 protrudes from the opening of the bottom portion 22 of the second film body 20 and is exposed from the first film body 10. The first film body 10 is fixed to the second film body 20 by adhesive tape M1 which is attached from the outer surface of the first film body 10 that protrudes from the bottom portion 22 of the second film body 20 to the bottom portion 22 of the second film body 20 (near the bottom portion 22 of the front sheet 20a). In this way, the first film body 10 and the second film body 20 are fixed to each other. In the rice packaging body 1, the leading edge 21 of the second film body 20 is provided to correspond to the discharge port 11 of the first film body 10, and the bottom edge 22 of the second film body 20 is provided to correspond to the rice receiving port 12 of the first film body 10.

[0016] Rice can be packed into the first film body 10 through the rice storage opening 12 of the rice packaging body 1. Here, the line connecting the connecting edges 23d of the second film body 20, which are opposite each other in the left-right direction, is designated as the rice storage guideline 25. The rice storage guideline 25 is a guideline for when to put in the rice 50. When the rice 50 is packed up to the rice storage guideline 25, it is preferable to fold the rice storage opening 12 (bottom edge 22) side of the first film body 10 and the second film body 20 to seal the rice 50 later. The rice storage guideline 25 may be an actual line indicated as a guideline, or if no line is indicated, a line connecting the connecting edges 23d can be assumed as an approximate guideline and designated as the rice storage guideline 25.

[0017] Furthermore, the inclined line that faces the left and right sides and extends from the connecting edge 23d to the edge of the rice storage opening 12 is designated as the inclined fold line 26a. The angle φ of the inclined fold line 26a with respect to the left and right direction is the same as the angle φ of the inclined edge 23b with respect to the left and right direction. In addition, the first film body 10 is provided with three lines (first fold line 26b, second fold line section 26c, and third fold line section 26d) that run in the left and right direction (lines parallel to the rice storage guideline 25) between the rice storage opening 12 and the rice storage guideline 25. The inclined fold line 26a, the first fold line 26b, the second fold line section 26c, and the third fold line section 26d may or may not have lines displayed.

[0018] The rice 50 is placed into the rice packaging 1 by opening the rice storage opening 12. After the rice 50 is placed up to the rice storage guideline 25, the rice packaging 1 on the rice storage opening 12 side is folded and secured with adhesive tape M2 or the like.

[0019] As shown in FIG. 2, the folding of the rice packaging body 1 first involves folding two opposing inclined folding lines 26a. The two opposing inclined folding lines 26a are folded in the same direction with respect to the normal direction on the surface of the rice packaging body 1. In this embodiment, it is folded towards the front side of the paper surface of FIG. 2. Next, the first folding line 26b, the second folding line portion 26c, and the third folding line portion 26d are folded in sequence. The folding direction is the same as that of the inclined folding line 26a, folding towards the front side of the paper surface of FIG. 2 to obtain the state shown in FIG. 3. Then, in order to fix the folded portion, an adhesive tape M2 is attached along the left - right direction across the folded portion and the outer surface of the second film body 20. In this way, the rice - packed food 100 is formed. Thus, by folding the rice storage opening 12 and the bottom portion 22 multiple times (in this embodiment, three times for the first folding line 26b, the second folding line portion 26c, and the third folding line portion 26d), it is possible to reduce the leakage of oil from the oil - containing rice 50 through the rice storage opening 12. And the openings of the rice storage opening 12 and the bottom portion 22 are not exposed to the outside because they are folded like the first folding line 26b, the second folding line portion 26c, and the third folding line portion 26d, so rainwater and foreign substances cannot easily enter the inside of the first film body 10 from the outside. Also, the folded portions of the first folding line 26b, the second folding line portion 26c, and the third folding line portion 26d are fixed by attaching the adhesive tape M2 and are made difficult to be seen from the outside.

[0020] To eat the rice 50 contained in the rice - packed food 100, first, pick the knob 24a of the unsealing strip portion 24 and pull it so as to peel the unsealing strip portion 24 from the tip portion 21 towards the bottom portion 22. Then, the second film body 20 is split. Note that a triangular mark with the apex directed downward as shown in the lower side of FIG. 2 where the rice packaging body 1 is folded is described on the knob 24a. Here, the lower end of the unsealing strip portion 24 is located at the portion folded by the first folding line 26b, the second folding line portion 26c, and the third folding line portion 26d. Therefore, the unsealing strip portion 24 does not completely separate from the second film body 20, and there is no hassle of treating the separated unsealing strip portion 24 as garbage.

[0021] Thereafter, when the split second film body 20 is peeled while being displaced toward the base portion 22 side, as shown in FIG. 4, the first film body 10 is exposed, and the second film body 20 can be disposed on the base portion 22 side thereof. The discharge port 11 at the tip of the first film body 10 is open. Therefore, by gripping the discharge port 11 of the first film body 10 exposed from the second film body 20 with the mouth and pressing the side surface or the bottom of the first film body 10 by hand or the like, the cooked rice 50 can be extruded and eaten. Here, since the discharge port 11 of the first film body 10 to be gripped by the mouth is enclosed and covered by the second film body 20, even if the cooked rice packaged food 100 is carried, it is hygienic. Further, the first film body 10 is formed at an angle θ = approximately 34 degrees (see FIG. 1) on the discharge port 11 side, so that the rice grains can be suitably discharged from the discharge port 11.

[0022] At this time, the unsealing strip portion 24 that split the second film body 20 is attached to the cooked rice package 1 (cooked rice packaged food 100) in a string-like state. Using this unsealing strip portion 24, the second film body 20 disposed so as to hang on the side opposite to the discharge port 11 of the first film body 10 can be tied. Thereby, the split and peeled second film body 20 and the unsealing strip portion 24 can be compactly stored, and the tied second film body 20 can be used as a handle and held by hand to make it easier to grip the discharge port 11.

[0023] Furthermore, as shown in the modified example in Figure 5, the rice packaging body 1 can also have the rice storage opening 12 of the first film body 10 positioned to align with the edge of the bottom portion 22 of the second film body 20. In addition, although not shown, the rice storage opening 12 of the first film body 10 can also be positioned closer to the front portion 21 than the edge of the bottom portion 22 of the second film body 20. This makes it easier to fold along the first fold line 26b and the second fold line portion 26c. In the rice packaging body 1 of Figure 5, the first film body 10 and the second film body 20 are fixed together by double-sided tape M3 that adheres to each other. Specifically, for example, the double-sided tape M3 is attached to both the inner surface of the second film body 20 and the outer surface of the first film body 10 (in the modified example shown in Figure 5, it is preferable that the second straight edge portion 23c and the corresponding inclined line portion of the first film body 10 are formed to extend downward by a predetermined length (a reasonable length) to facilitate bending).

[0024] As described above, according to this embodiment, the rice packaging body 1 comprises a first film body 10 formed from a film material into a triangular bag shape, with a discharge port 11 at its top and a rice storage port 12 on the side opposite the discharge port 11, and a second film body 20 formed from a film material into a triangular bag shape, provided on the outside of the first film body 10 so as to enclose at least the discharge port 11 of the first film body 10, with a tip portion 21 corresponding to the discharge port 11 being sealed and a bottom portion 22 corresponding to the rice storage port 12 being open.

[0025] As a result, the rice packaging body 1 allows the user to eat the packaged rice by holding the discharge opening 11 in their mouth. This makes it easy to eat even rice dishes that are difficult to form into a ball, such as fried rice or seasoned rice, where oil adheres to the rice grains. In particular, it makes it easy for infants, the elderly, and people with disabilities to eat rice even if the rice grains are not tightly bound together. Therefore, with the rice packaging body 1 of this embodiment, it is possible to eat rice without spilling it, regardless of the binding strength between the rice grains.

[0026] Furthermore, the second film body 20 has an opening strip 24 formed in a strip shape from the leading edge 21 to the bottom edge 22, which allows the second film body 20 to be separated. As a result, the rice packaged food 100, in which rice is packaged in the rice package body 1, can be easily opened.

[0027] Furthermore, the opening band 24 is formed in a straight line from the leading edge 21 of the second film body 20 to a point midway along the bottom edge 22. As a result, the opening band 24 remains attached to the food packaging body 1 even after opening, and the peeled-off second film body 20 can be tied and bundled together using the string-like opening band 24.

[0028] Furthermore, the rice-receiving opening 12 of the first film body 10 is provided protruding from the bottom portion 22 of the second film body 20. This makes it easier to open the rice-receiving opening 12 when refilling the rice.

[0029] Furthermore, the first film body 10 is fixed to the second film body 20 by adhesive tape M1 which is applied from the portion protruding from the bottom edge 22 of the second film body 20 to the bottom edge 22 of the second film body 20. As a result, the first film body 10 is securely fixed to the second film body 20 with a simple configuration using adhesive tape M1 without using welding or the like, and the relative positional relationship between the first film body 10 and the second film body 20 can be maintained even when food is placed inside.

[0030] Furthermore, the rice-receiving opening 12 of the first film body 10 is positioned at a location aligned with the edge of the bottom portion 22 of the second film body 20, or on the tip portion 21 side of the edge of the bottom portion 22. This makes it easier to fold the bottom portion 22 (rice-receiving opening 12) compared to when the first film body 10 protrudes from the bottom portion 22.

[0031] Furthermore, the first film body 10 and the second film body 20 are fixed to each other by double-sided tape M3. This allows the first film body 10 to be securely fixed to the second film body 20 with a simple configuration using double-sided tape M3 without using welding or other methods, and the relative positional relationship between the first film body 10 and the second film body 20 can be maintained even when food is placed inside.

[0032] Furthermore, the edge of the second film body 20 corresponding to the leading edge 21 in the direction along the perpendicular VL of the second film body 20 is provided with a straight first straight edge portion 23a along the perpendicular VL of the second film body 20, and the edge of the second film body 20 corresponding to the bottom edge 22 in the direction along the perpendicular VL of the second film body 20 is provided with a straight second straight edge portion 23c along the perpendicular VL of the second film body 20, and the second film body 20 is provided with an inclined edge portion 23b connecting the first straight edge portion 23a and the second straight edge portion 23c, and the part where the second straight edge portion 23c and the inclined edge portion 23b connect is called a connecting edge portion 23d, and the line connecting the opposing connecting edge portions 23d in the horizontal HL direction perpendicular to the perpendicular VL of the second film body 20 is called the rice storage guideline line 25. This makes it easy to understand how much rice should be stored in the rice packaging body 1 when storing rice.

[0033] The first film body 10 is made of a resin material containing polyethylene, and the second film body 20 is made of a resin material containing polypropylene. This allows rice to be smoothly discharged from the discharge port 11 of the first film body 10, and provides a rice packaging body 1 equipped with a second film body 20 that can be manufactured at low cost.

[0034] The packaged rice food 100 contains rice 50. Specifically, the packaged rice food 100 contains rice 50 filled up to the rice storage guideline 25, and the rice package 1 has the first film body 10 and the second film body 20 at opposing edges on the second straight edge 23c side both bent at an angle equivalent to the angle at which the inclined edge 23b is inclined with respect to the horizontal HL direction perpendicular to the perpendicular line VL, and the bent portion is further bent multiple times (for example, three times) along a line parallel to the rice storage guideline 25, and the bent portion is fixed with adhesive tape M2. This makes it possible to provide a packaged rice food 100 that is compact and convenient to carry, and that can be eaten without spilling rice, regardless of the binding force between the rice grains.

[0035] Although embodiments of the present invention have been described above, the present invention is not limited to these embodiments and can be implemented with various modifications. For example, in this embodiment, the discharge port 11 of the first film body 10 is open from the beginning, but it may be lightly welded or an opening strip may be formed so that it opens just before the rice 50 is eaten. Furthermore, even if the rice packaging body 1 does not have a second film body 20, and is instead composed only of a first film body 10 formed from film material into a triangular bag shape, with a discharge port 11 at the top and a rice storage port 12 on the side opposite the discharge port 11, the desired effects, such as being able to eat the rice without spilling, can be achieved regardless of the binding force between the rice grains.
