It is a perspective view which shows the other Example of the rice lump used for the packaged rice lump packaged in the bag shape shown in FIG.

The present invention will be described below with reference to the drawings.
As shown in FIGS. 1 to 3, the packaging sheet (1) is formed by sandwiching a sheet-like food (4) between a rectangular transparent outer film (2) and an inner film (3).

The outer film (2) is a vertically long film in the present embodiment, and a plurality of cuts (23) and (23) are formed in a perforated shape at a substantially central portion (18) in the longitudinal direction. It has a score line (22) that crosses. The outer film (2) is cut by breaking the connection between the notches (23) and (23) by receiving a force perpendicular to the outer film (2) against the notch line (22). It has become.
The outer film (2) can have a length in the longitudinal direction of about 24 cm and a length in the width direction of about 14 cm.

Inside the outer film (2), a narrow cover film (24) is provided along the cut line (22) to close the cuts (23) and (23). The cover film (24) is thermally welded to the outer film (2) at one side in the longitudinal direction (width direction of the outer film (2)) so as to be along the cutting line (22) in the vicinity of the cutting line (22). 24a) (see FIG. 9).
By covering the cuts (23) and (23) with the cover film (24), it is possible to prevent moisture and the like from entering the inside of the packaging sheet (1) from the cuts (23) and (23). 4) can be kept dry.
The cover film (24) can have the same length (about 14 cm) as the width of the outer film (2) in the longitudinal direction and the width (longitudinal direction of the outer film (2)) of about 1 cm.

The inner film (3) is composed of two inner film pieces (31) and (31) having the same shape, and the inner edges of each other are overlapped by about 1 cm at the center (18) of the outer film (2). Overlapping.
Each of the inner film pieces (31) (31) is formed so as to have substantially the same shape as the outer film (2) in a state of being stacked as described above.

  As the inner film (3), 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 (3) (the inner film pieces (31) and (31)), an embossed film in which concave portions and convex portions are uniformly distributed can be used. By using an embossed film, the detachability from the rice lump (6) can be increased, and the rice grains can be prevented from adhering to the inner film (3).

  The sheet-like food (4) is a sheet-like seaweed in the examples. The sheet-like food (4) is not particularly limited as long as it is a thin food such as those obtained by forming a rag kombu into a sheet, or a thinly stretched koji.

The sheet-like food (4) can have a length of about 19 cm in the longitudinal direction and a length of about 9 cm in the width direction.
The sheet-like food (4) can be of a substantially rectangular shape, but as shown in the figure, a rectangular shape with a chamfered corner or a shape with a rounded chamfered end in the longitudinal direction is used. By using a thing, as will be described later, the rice cake (6) can be easily dropped from the packaging sheet (1).

  As shown in FIG. 1 to FIG. 3, laver (41) is placed at the approximate center position of the outer film (2) with the cover film (24) attached on the inside, and the inner film (3) is formed from there. The film pieces (31) and (31) are placed so that they slightly overlap at the center (18), and the outer film (2) and the inner film are placed along the periphery of the outer film (2) so as to surround the sheet-like food (4). The packaging sheet (1) is formed by welding the film (3) linearly (11) (11). In addition, welding is not given to the overlapping part of the inner film pieces (31) (31) which becomes the center part (18) of the packaging sheet (1).

  In addition, it is desirable to prevent welding of the sheet-like food (4) by applying welding (12) to one end or the vicinity of both ends in the longitudinal direction of the sheet-like food (4).

The lump (6) is packaged on the packaging sheet (1) having the above-described configuration.
As shown in FIG. 2, the rice lump (6) packaged in the packaging sheet (1) is a lump that is flattened by hardening white rice, rice, etc. Preferably, both side surfaces are substantially parallel, and the both side surfaces are connected to each other by a flat or curved peripheral surface.
The rice lump (6) may be partially or entirely sprinkled with sprinkled food such as sesame, placed with ingredients, or sandwiched with ingredients.

  The illustrated rice cake (6) is a triangular rice ball having a height of about 7 cm and a width of about 4 cm, but can also be a round rice ball or a rectangular rice ball. In order to make the rice lump (6) slide well from the inner film (3) and drop it, the sides and corners of the rice lump (6) are preferably chamfered. The chamfering can be exemplified by round chamfering. R is preferably 5 mm or more, and more preferably approximately 8 mm.

  As shown in FIG. 2, the rice cake (6) having the above configuration is placed on a packaging sheet (1) with the inner film (3) side facing upward. In the case of a triangular rice ball, the rice lump (6) has a central surface (18) of the packaging sheet (1) when one of the peripheral surfaces (referred to as the bottom surface) is folded. Place them so that they face each other.

  Note that the packaging sheet (1) may be folded in advance in a U shape with the central portion (18) in between, and the mass of rice (6) may be sandwiched.

  As shown in FIG. 2, after placing the rice cake (6) on the packaging sheet (1), as shown by the arrow D in the figure, one end of the packaging sheet (1) is wrapped around the rice cake (6) so as to wrap the rice cake (6). 6).

  Next, as shown in FIG. 4, the end portion of the packaging sheet (1) is placed along the peripheral surface of the rice chunk (6) as indicated by the arrow E (in FIGS. 4 to 6, the inner film (3 ) And sheet-like food (4) are not shown). Subsequently, as shown by an arrow F in FIG. 5, one corner of the other end of the packaging sheet (1) is covered so as to wrap the mass of rice (6), and the other is also shown as an arrow G in FIG. Put the horn over the rice block (6).

  Subsequently, as shown in FIG. 6, the end of the intersecting packaging sheet (1) is sealed by the fastening means (5), whereby a packaged rice lump can be obtained. Although the illustrated fastening means (5) is a tape, it can be sealed by using a label on which the date of manufacture and contents are described, or by welding.

  Finally, as shown in FIG. 7, it is desirable to fold the both ends of the central portion (18) of the packaging sheet (1) upward and to secure the locking means (51) such as a tape or a seal. Seal with. Accordingly, the appearance of the packaged rice lump can be improved without sacrificing the appearance, and when the display is performed at the store with the bottom surface on which the central portion (18) is formed facing downward.

  In the above case, as shown in FIG. 8, the locking means (51) is made of a thick or difficult-to-bend material, and an adhesive or the like is formed on the surface of the locking means (51) on the outer film (2) side. Can be provided, and can have a pasting part (51a) having sticking property and a pressing part (51b) having no sticking property to which no adhesive or the like is applied. However, the pasting part (51a) is stuck to the outer film (1) wound around the rice lump (6), and the folded center part (18) of the packaging sheet (1) is pressed by the holding part (51b), It is desirable to prevent the bent portion from returning to its original position. This effect will be described later.

  FIG. 9 shows a cross-sectional view taken along line BB of FIG. 6 of the packaged rice lump in which the rice lump (6) is packaged by the packaging sheet (1). As shown in the figure, the rice cake (6) is covered with the inner film pieces (31) and (31), the sheet-like food (4) and the outer film (2) constituting the inner film (3) from the inside. The bottom surface of the lump (6) is the center of the cover film (24) and the inner film pieces (31) (31) that close the cut line (22) of the outer film (2) from the inside at the center (18). The overlapping portion is opposed to the sheet-like food (4).

  By arranging the cover film (24) on the inner surface side of the outer film (2), the cut line (22) is blocked so that the cuts (23) and (23) do not communicate with the inside of the packaging sheet (1). Therefore, moisture or the like does not enter the inside of the packaging sheet (1), and the sheet-like food (4) can be kept in a crisp state.

The packaged rice lump having the above configuration can be unpacked in the following manner.
First, the locking means (51) is peeled off, and both ends of the central portion (18) are unfixed.
In this state, the bottom surface of the packaged rice cake is directed downward, and the top of the packaged rice cake is picked with a finger as shown by arrows H and H in FIG. 9, and the rice cake (6) is moved downward.

The locking means (51) is formed of the gluing part (51a) and the holding part (51b) as described above, and the folded central part (18) of the packaging sheet (1) is pressed by the holding part (51b). By adopting a configuration that only needs to be kept, it is possible to save the trouble of peeling off the locking means (51). That is, even if the locking means (51) is not peeled off, if the rice cake (6) is pushed down by picking the packaged rice cake with the arrows H and H in FIG. The force applied to the part (18) is disengaged from the locking means (51). Therefore, the step of unwrapping can be further simplified.
Of course, the locking means (51) may be configured such that a part of the glue portion (51a) is adhered to the bent central portion (18).

  When the rice block (6) is pushed downward, as shown in FIG. 10, a force in a direction substantially perpendicular to the score line (22) provided on the outer film (2) acts from the rice block (6). To do. Thereby, the connection part of notches (23) and (23) is cut, the outer film (2) is separated at the notch line (22), and the outer film (2) is opened (25).

  By keeping the opening (25) facing down as it is, the food mass (6) can transform the sheet-like food (4) into the outer film (2) and the inner film (3) by its own weight. Fall while pulling from between. As the lump (6) is dropped, the inner film (3) is also opened when the inner film pieces (31) and (31) are unoverlapped.

  At this time, if the rice mass (6) does not fall smoothly due to its own weight, the finger holding the upper end of the packaged rice mass is lowered downward so that the rice mass (6) moves downward, and the rice mass ( 6) Press down or shake gently downward.

  The rice lump (6) is completely detached from the packaging sheet (1), so that the rice lump (6) is directly covered with the sheet-like food (4) as shown in FIG. ).

  The rice lump (6) unwrapped and covered with the sheet-like food (4) can be eaten by winding the end of the sheet-like food (4) around the rice lump (6).

  In addition, as mentioned above, by chamfering the sides and corners of the lump (6), the contact resistance with the inner film (3) can be reduced, and the lump (6) is deformed. And can be dropped smoothly.

  Furthermore, as described above, the sheet-like food (4) is bent between the outer film (2) and the inner film (3) by chamfering the corners of the sheet-like food (4) or rounding the edges. Since the sheet-like food (4) is not torn between the outer film (2) and the inner film (3), it is not sandwiched between the parts (for example, indicated by reference numeral (15) in FIG. 4). It can be pulled out from between.

  The packaged rice lump of the present invention is a step in which the central portion (18) of the packaging sheet (1) is directed downward and the top of the packaged rice lump is picked, or after the locking means (51) is removed, The rice mass (6) covered with the sheet-like food (4) can be obtained only by picking the top of the mass, so the packaged rice is as simple as possible compared to the conventional packaged rice mass. You can unwrap the lump.

  In the above description, dimensions and desirable shapes are illustrated as appropriate for easy understanding of the description, but it is obvious that the present invention is not limited to the above dimensions and shapes. For example, what is necessary is just to produce the magnitude | size of a packaging sheet (1) according to the magnitude | size of a rice lump (6).

  FIG. 12 shows an embodiment in which the shape of the packaging sheet (1) is different. As shown in FIG. 4, when the corners of the inner film pieces (31) and (31) constituting the packaging sheet (1), that is, the outer film (2) and the inner film (3) are chamfered, The bent portion of the packaging sheet (1) shown in (15) can be reduced or eliminated, and the packaging can be unwrapped more smoothly.

  FIG. 13 shows an embodiment in which the packaging sheet (1) shown in FIGS. 1 to 3 is formed in a bag shape. Also in this case, the outer film (2) is separated at the cut line (22) by picking the upper end of the packaged rice lump with the center (18) facing downward, and the lump (6) is A rice lump (6) that falls by its own weight and is directly wrapped with a sheet-like food (4) can be obtained in the same manner as described above.

FIG. 14 shows another embodiment of the rice chunk (6) that can be accommodated in the bag-shaped packaged rice chunk shown in FIG. As shown in FIG. 14, the rice chunk (6) is shaped so as to be split (61) into a plurality of chunks (60) and (60). Thereby, since the rice lump (6) can be divided into each lump (60) (60), it can be made easy to eat.
Although not shown in the figure, the sheet food (4) that wraps the rice chunk (6) is also provided with notches such as perforations along the divided portion (61) of the chunk (60) (60). Thus, when the lump (60) (60) is broken, the sheet-like food (4) is also cut into one body, and a rice lump directly wrapped by the sheet-like food (4) can be obtained.

  In addition, a plurality of tastes can be enjoyed with one packaged rice lump by placing or putting different ingredients (62), (63), (64) on each lump (60) (60).

  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.
