Hereinafter, the present invention will be described with reference to the drawings.
1 to 3 show a packaging sheet (12) of the packaged rice lump (10) of the present invention.
As shown in FIGS. 1 to 3, the packaging sheet (12) includes a rectangular and transparent outer film (20) and an inner film piece (approximately half the width of the short side in the width direction of the outer film (20)). The sheet-like food (50) is sandwiched between the inner film (40) made of 41) and (41).

As shown in FIGS. 1 and 2, the outer film 20 is a vertically long rectangular film in this embodiment, and has a length in the longitudinal direction of about 23 cm and a length in the width direction of about 14 cm. The outer film (20) has a tear portion (24) formed by forming notches (21) with a predetermined interval over the entire length in the longitudinal direction at the center in the width direction. The outer film (20) can be easily torn by pulling the tear portion (24) in the width direction.
On the back surface of the outer film (20), a cover film piece (22) that closes the tear (24) made of the cut (21) is provided. The cover film piece (22) is narrow (for example, 1.5 cm), and is provided so as to block the tear (24) over its entire length. The cover film piece (22) is arranged so as to cover the tearing part (24), and one side in the longitudinal direction is joined to the outer film (20) by heat welding (17) or the like, so that the outer film (20) is joined. Can be attached.
The cover film piece (22) serves to prevent moisture and the like from entering the cut (21) and maintain the dry state of the sheet-like food (50) in the packaging sheet (12).

The sheet-like food (50) can be exemplified by sheet-like seaweed. The sheet-like food (50) is placed substantially at the center on the back side of the outer film (20).
The sheet-like food (50) can be a substantially rectangular one, but as shown in FIGS. 1 and 2, a rectangular shape with chamfered corners or a longitudinal end portion can be used. By using a rounded chamfered shape, as described later, the inner film piece (41) constituting the outer film (20) and the inner film (40) is removed from the rice lump (60) and the sheet-like food (50). It can be easily pulled out.
In the present embodiment, the sheet-like food product (50) can have a shape having a length of about 16 cm in the longitudinal direction and a length of about 8 cm in the width direction.

In the examples, the sheet-like food (50) uses sheet-like seaweed, but it is not particularly limited as long as it is a thin food.
For example, a thinly stretched cocoon or a coconut kelp formed into a sheet.

As shown in FIGS. 1 and 2, the inner film (40) is composed of two film pieces (41) (41) having the same shape, and the inner edges of each other are arranged in the center in the width direction of the outer film (20). It overlaps with an overlap width of about 1 cm on the tearing part (24).
That is, in this embodiment, each film piece (41) (41) has a length in the longitudinal direction of about 23 cm which is the same as that of the outer film (20), and a length in the width direction of about 7.5 cm.

  As the inner film (40), it is desirable to use a film made of a material to which rice grains do not easily adhere. For example, as the inner film (40), that is, the inner film pieces (41) and (41), an embossed film in which concave portions and convex portions are uniformly distributed can be used. By using the embossed film, it becomes difficult for the rice grains from the lump (60) to adhere, and it is possible to prevent the rice grains from adhering to the inner film (40) and the like.

  As shown in FIGS. 2 to 3, the sheet-like food (50) is placed in the approximate center of the back side of the outer film (20), and the inner film piece (41) constituting the inner film (40) is formed thereon. (41) are placed so that the inner edges of each other overlap on the split part (24), and surround the outer film (20) and the inner film along the periphery of the outer film (20) so as to surround the sheet-like food (50). The packaging sheet (12) is formed by welding (18) the film (40) linearly. Note that welding is not performed on the overlapping portions of the inner film pieces (41) and (41).

  Also, as shown in FIGS. 2 and 3, in order to prevent the sheet-like food (50) from shifting, the inner film pieces (41) are arranged near one end or both ends in the longitudinal direction of the sheet-like food (50). ) (41) is preferably welded (19) to the outer film (20).

  The packaging sheet (12) formed as described above is provided with a cover film piece (22) that closes the tearing portion (24) from the inside, so that moisture entering the inside of the packaging sheet (12) from the cut (21) is provided. And the sheet-like food (50) in the packaging sheet (12) can be kept dry.

The lump (60) is packaged using the packaging sheet (12) having the above configuration.
The rice lump (60) can be exemplified by a flat-shaped lump that hardens white rice or rice. Preferably, both side surfaces are substantially parallel, and the both side surfaces are connected to each other by a planar or curved peripheral surface.
The rice lump (60) may be partially or entirely sprinkled with sprinkled food such as sesame, placed with ingredients, or sandwiched with ingredients.

  In the embodiment, the rice cake (60) is a triangular rice ball, but it may be a round rice ball or a square rice ball.

A procedure for packaging the rice cake (60) with the packaging sheet (12) having the above-described configuration will be described below.
As shown in FIG. 2, the rice cake (60) is placed on the packaging sheet (12) with the inner film (40) side facing upward. When the rice cake (60) is a triangular rice ball, the rice cake (60) is overlapped with the split portion (24) at a position slightly above the center of the packaging sheet (12), and the rice cake (60 ) Is placed so that the approximate center of the side faces the tearing portion (24).

  Next, as shown by the arrow C in FIG. 2, one end in the longitudinal direction of the packaging sheet (12) is placed on the rice chunk (60) so as to wrap the rice chunk (60). Subsequently, as indicated by an arrow D in FIG. 5, both corners of one end of the packaging sheet (12) are set along the circumferential surface of the rice lump (60).

  Next, from the state of FIG. 5, as shown by arrow E in FIG. 6, one corner of the other end of the packaging sheet (12) is covered so as to wrap the rice cake (60), and further, by arrow F in FIG. As shown, the other corner is put over the rice block (60).

  Finally, as shown in FIG. 7, the packaged rice lump (10) can be obtained by stopping the ends of the intersecting packaging sheet (12) by fastening means (16) such as a tape. The fixing means (16) of the embodiment is a tape, but it can be stopped by using a label on which the date of manufacture, contents, etc. are described, or by welding.

FIG. 8 is a cross-sectional view of the packaged rice lump (10) taken along the line BB in FIG.
The rice chunk (60) is covered with the inner film pieces (41) (41), the sheet-like food (50), and the outer film (20) constituting the inner film (40) from the inside. (41) and (41) overlap so as to pass through the center of the lump (60).

  The packaged rice lump (10) obtained as described above can be unpacked in the following two steps.

  As a first step, the edges of the outer film (20) positioned on the left and right sides of the tear (24) are pulled left and right as indicated by arrows G and G in FIG. As a result, as shown in FIG. 9, the outer film (20) is torn at the tearing portion (24), and the divided one outer film (20) and inner film piece (41) are separated into a sheet-like food (50). Can be pulled out in a state left in the rice lump (60).

  Next, as a second step, the other half of the remaining outer film (20) and the inner film piece (41) are pulled in the direction of arrow H in FIG. Pulled out from the food (50), as shown in FIG. 10, a rice cake (60) directly covered with the sheet-like food (50) is obtained.

  The rice lump (60) that has been unwrapped by the above two steps and directly covered with the sheet-like food (50) is wrapped around the end of the sheet-like food (50) around the rice lump (60). can do.

  The present invention does not require complicated steps as in the prior art, and the packaging can be unwrapped with only two simple steps.
