FIG. 14: is a perspective view of the packaged rice lump which packaged the rice lump in the bag shape using the packaging sheet of this invention.

The present invention will be described below with reference to the drawings.
As shown in FIGS. 1 to 3, the packaging sheet (1) is a rectangular and transparent outer film (2), and three film pieces (3a) (3a) arranged side by side in the longitudinal direction of the outer film (2). A substantially rectangular sheet-shaped food (4) is sandwiched between the inner film (3) made of 3b) and (3c).

  The illustrated packaging sheet (1) is formed in a vertically long shape, and has a length in the longitudinal direction of about 26 cm and a length in the width direction of about 13 cm. In addition, the rice lump (6) to be packaged by the packaging sheet (1) is a lump that is flattened by solidifying white rice or crisp rice, as shown in FIG. It is a rice ball of about 3cm.

The outer film (2) is a vertically long film in this embodiment, and perforated cuts (21) are formed at two locations parallel to the width direction orthogonal to the longitudinal direction. The cut (21) can be divided by applying a force in a substantially vertical direction.
The cuts (21) are formed with a wider interval than the bottom surface (61) (FIG. 3) of the rice lump (6). Hereinafter, the film part between the notches (21) and (21) is referred to as the central piece (2b), and the film part continuous across the center piece (2b) and the notch (21) is referred to as the outer piece (2a) (2c). Called.

  The interval between the notches (21) and (21), that is, the length of the central piece (2b) is determined when the bottom (61) of the rice cake (6) is placed on the central piece (2b) and the rice cake (6) is packaged. It is preferable that the notch (21) is formed at a position of about 1/2 to 1/4 of the height of the rice lump (6).

  A thin cover film piece (23) is attached to the outer film (2) from the inside along the cut (21). The cover film piece (23) can have a width of about 1.5 mm, and a longitudinal side of the cover film piece (23) is welded (17) to the outer film (2) along the cut (21). Thus, the incision (21) is covered from the inside to prevent moisture and the like from entering the packaging sheet (1).

  As shown in FIG. 2, the cover film piece (23) is preferably welded (17) to the outer pieces (2a) and (2c) of the outer film (2). Thus, in the step of unpacking which will be described later, when the outer piece (2a) (2c) is pulled out leaving the central piece (2b), the cover film piece (23) is pulled out together with the outer piece (2a) (2c). This is so that it does not remain on the side of the rice cake (6).

  An inner film (3) is provided inside the outer film (2). The inner film (3) is composed of three film pieces (3a) (3b) (3c) arranged side by side in the longitudinal direction of the outer film (2). Adjacent film pieces are connected to the outer film (2). ) On the incision (21) with an overlap width of about 1 cm.

  As shown in FIGS. 3 and 4, the overlapping part of the film piece (3a) and the film piece (3b) and the overlapping part of the film piece (3b) and the film piece (3c) can be easily peeled at a plurality of points. Welding (31) is applied and connected to each other.

  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, each film piece (3a) (3b) (3c) of the inner film (3) can be an embossed film in which concave portions and convex portions are uniformly distributed. 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).

A sheet-like food (4) such as seaweed is sandwiched between the outer film (2) and 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.
In the illustrated embodiment, the sheet-like food (4) has 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) is disposed between the outer film (2) and the inner film (3), and the outer film (2) and the inner film (3) are heat-welded as shown in FIGS. (11) By doing so, a packaging sheet (1) is produced.

  The thermal welding (11) between the outer film (2) and the inner film (3) is performed by the outer piece (2a) (2c) of the outer film (2) and the outer film piece (3a) of the inner film (3). It is desirable to apply only to the outer peripheral side of (3c).

  Also, in order to prevent the sheet-like food (4) from shifting in the packaging sheet (1), the outer film (2) and the inner film (3) are placed at a plurality of locations outside the sheet-like seaweed (4). It is desirable to perform spot welding (12). Also in this case, it is desirable that the spot welding (12) is applied only to the outer pieces (2a) (2c) of the outer film (2) and the outer film pieces (3a) (3c) of the inner film (3).

The lump (6) is packaged on the packaging sheet (1) having the above-described configuration.
As shown in FIG. 3, the rice lump (6) packaged in the packaging sheet (1) is a lump that is flattened by solidifying 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 (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 3 cm, but can also be a round rice ball or a rectangular rice ball.

  As shown in FIG. 3, 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 rice ball (6), when the rice ball (6) is a triangular rice ball, one of the peripheral surfaces (bottom surface (61)) is bent at the center of the inner film (3) when the packaging sheet (1) is folded (3b). ).

  Note that the packaging sheet (1) may be folded in a U shape in advance to sandwich the lump of rice (6).

  As shown in FIG. 3, after putting the rice cake (6) on the packaging sheet (1), as shown by the arrow C 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). At this time, the bottom surface (61) of the lump (6) and the central piece (2b) of the outer film (2) face each other through the central film piece (3b) of the inner film (3) and the sheet-like food (4). Cover the packaging sheet (1) as shown.

  Next, as shown in FIG. 6, the end portion of the packaging sheet (1) is placed along the peripheral surface of the rice chunk (6) as indicated by an arrow D. Subsequently, as shown by an arrow E in FIG. 7, the other end of the packaging sheet (1) is covered so as to wrap the rice cake (6), and, as shown by an arrow F in FIG. Put on (6).

  Subsequently, as shown in FIG. 8, 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.

  As shown in FIG. 9, the left and right ends of the packaged rice lump are bent upward and locked by means of heat welding (13) or locking means such as a tape or a seal.

  By bending both ends of the packaged rice lump upward, the appearance is not impaired, and the packaged rice lump can be sat well when displayed at a storefront with the lower side as the bottom side.

  As shown in FIG. 9, the packaged rice lump (7) wrapped by the packaging sheet (1) of the present invention has a cut (21) at a position about 1/4 to 1/2 from the bottom side. ing.

The packaged rice lump obtained as described above can be unpacked in the following manner.
First, as shown in FIG. 10, the packaged rice chunk (7) has the finger (100) (100) (the outer film (2) on the apex side facing the bottom surface (61) of the rice chunk (6) of the packaging sheet (1). 101) Pick and pull. As a result, the lump (6) is pushed downward, and tensile force is applied to the outer film (2) and the inner film (3), and the outer pieces (2a) (2c) and the central piece (2b) of the outer film (2) are applied. ) Are cut at the cuts (21) and (21), and the inner film (3) is spot welded between the film piece (3a) and the film piece (3b), and between the film piece (3b) and the film piece (3c) ( 31) peels off. As a result, as shown in FIG. 11, the outer pieces (2a) (2c) and the film pieces (3a) (3c) are peeled off, and the central piece (2b) and the inner film (3) of the outer film (2) are peeled off. Only the film piece (3b) remains in the lump (6).

  At this time, as described above, the cover film piece (23) is welded (17) to the outer piece (2a) (2c) side of the outer film (2), so that the outer piece (2a) (2c) The cover film piece (23) is pulled out together and does not remain on the side of the rice cake (6).

  As shown in FIG. 11, the sheet-like food (4) comes into direct contact with the upper portion of the rice lump (6), and in this state, the center piece (2b) is grasped and the sheet-like food (4 ) Can be eaten.
