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) having a length substantially the same as the width of the rice chunk (60) in the longitudinal direction at the substantially center in the width direction and the longitudinal direction. The split part (24) is formed by forming a notch (21) at a predetermined interval, and the split part (24) is formed to be substantially the same as or slightly longer than the width (about 3.5 cm) of the rice lump (60). In the illustrated embodiment, the length is about 4 cm, which is slightly longer than the rice block (60).
The tear portion (24) can be easily torn by pulling 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). Accordingly, it is desirable that the cover film piece (22) is formed to be slightly longer than the tear portion (24), and is about 5 cm in the illustrated embodiment.

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).

  Since the packaging sheet (12) formed as described above has a configuration in which the tear portion (24) is provided only in a part of the outer film (20), the tear portion is formed in the longitudinal direction or the width of the outer film (20). Compared with the case of forming the entire length in the direction, it is possible to reduce entry of moisture and the like from the outside. More specifically, in the case of the present embodiment, compared with an outer film in which a cut is formed over the entire length in the longitudinal direction, intrusion of moisture and the like can be reduced to about 1/5 or less, and a packaging sheet ( The sheet-like food (50) in 12) can be maintained in a dry state.

  In addition, by providing a cover film piece (22) that closes the tear (24) from the inside, it is possible to further prevent moisture and other intrusion from entering the inside of the packaging sheet (12) from the cut (21). The sheet-like food (50) in (12) can be maintained in a dry state.

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. In the present embodiment, the width of the rice block (60) is about 3.5 cm.
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 mass (60) is a triangular rice ball, when the rice mass (60) is wrapped with the packaging sheet (12), the rice mass (60) so that the center of the bottom surface of the triangular rice ball faces the tear (24). 60) is placed.

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

  Next, from the state of FIG. 5, as shown by arrow D 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 E 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. When the fastening means (16) passes through the center of the packaging sheet (12) in the width direction, it is desirable to make a notch such as a perforation in the fastening means (16).

  In addition, after packaging the rice cake (60) with the packaging sheet (12), the edges of the packaging sheet (12) positioned on the left and right with the tear (24) in between are along the side surface of the packaging rice cake (10). It is desirable to bend and lock so as not to spread by a sealing means (not shown) such as a tape or a seal.

  When the edge of the packaging sheet (12) is bent as described above, it is desirable that the edge is not bent toward the bottom surface of the packaged rice lump (10) but is bent upward. This makes it possible to improve the sitting position of the packaged rice lump (10) when the display is performed at the store with the bottom surface facing downward.

  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 F and F in FIG. In addition, when the end edge is fixed or locked as described above, the fixed or locked state is released in advance.

  By pulling the edges of the outer film (20) to the left and right respectively, as shown in an enlarged view in FIG. 8, the outer film (20) is torn from the tear portion (24), and further, these edges are pulled. The outer film (20) is divided (25) in the longitudinal direction so as to be torn from the tear portion (24). In FIG. 8, the protrusion protruding from the inner side of the split portion (24) is the outer film (20) located between the cuts (21) and (21) cut by the division.

  Further, by pulling the edge, the outer film (20) is divided in the longitudinal direction over the entire length, and one of the divided outer film (20) and inner film piece (41) is 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 G 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.

  In the above description, in order to make the description easy to understand, appropriate dimensions and desirable shapes are illustrated, but it is obvious that the present invention is not limited to the above dimensions and shapes. For example, the length of the tearing portion (24), the size of the packaging sheet (12), and the like may be prepared according to the size of the rice chunk (60).

  In addition, by chamfering the corner of the sheet-like food (50) or rounding the edges, the sheet-like food (50) is placed at the bent portion of the outer film (20) and the inner film (40). Since it is not pinched, the outer film (20) and the inner film (40) can be pulled out from the sheet-like food (50) and the rice cake (60) without breaking the sheet-like food (50).

  The above description of the embodiments is for explaining the present invention and should not be construed as limiting the invention described in the claims or reducing the scope thereof. In addition, the configuration of each part of the present invention is not limited to the above embodiment, and various modifications can be made within the technical scope described in the claims.

FIG. 11 shows an embodiment in which the packaging sheet (12) shown in FIGS. 1 to 3 is formed in a bag shape. Also in this case, the tear portion (24) is formed only in a region that substantially matches the width of the bottom surface of the rice lump (not shown).
To unwrap, pull the edges of the outer film (20) located on the left and right sides to the left and right, respectively, and tear the outer film (20) over the entire length in the longitudinal direction of the outer film (20) in order from the tear (24).
