Can be packaged. In addition, since the outer film (2) and the first inner film (31) are weakly bonded, the first inner film (31) is removed and the sheet-like food is removed when the package is unwrapped from the packaged rice cake. The whole can be exposed, and the operation of rolling the rice cake onto the sheet-like food and winding the sheet-like food becomes easy.

It is a perspective view which shows the inner side of a packaging sheet. It is a perspective view which shows the outer side of a packaging sheet. It is sectional drawing of the state which fractured | ruptured along the AA line of FIG. 1 and mounted the rod-shaped rice lump on the 2nd inner film. It is another Example of a packaging sheet, Comprising: The 2nd inner film of FIG. 3 is extended to the end of an outer film. It is a disassembled perspective view of a packaging sheet. It is a perspective view of a packaged rice lump. It is a package rice lump perspective view in the middle of cutting a label and unwrapping. It is the perspective view which looked down at the state which unpacked and exposed the end of the sheet-like foodstuff. It is a perspective view of the state where the peripheral surface of the stick-shaped rice lump was made to adhere to the end of the sheet-like food exposed by unwrapping. It is a perspective view of the state where the welding on both sides of the first inner film was peeled off and the first inner film was turned to expose the entire length of the sheet-like food (4). It is a perspective view in the middle of rolling a stick-shaped rice lump on a packaging sheet, and winding a sheet-like food. It is a perspective view of the rod-shaped rice lump which wound the sheet-like food. It is a perspective view of the packed rice lump of another Example.

  As shown in FIGS. 1 to 3, the packaging sheet (1) has a sheet-like food (4) sandwiched between the outer film (2) and the first inner film (31), and the outer periphery of the outer film (2). The outer film (2) and the first inner film (31) are welded (11) (11) (12). Welding is performed with a welder, adhesive, etc., and the welds on both sides (11) and (11) on the long side of the outer film (2) are weak enough to be peeled off by hand after welding. It is a junction. The weld (12) on the short side of the outer film (2) may be weakly bonded as in the case of the welds (11) and (11) on both sides, but may be a strong bond that cannot be peeled off. In the figure, the sheet-like food (4) is drawn with a thick dashed line. The welds (11, 11, 12, 13, 13, 14) between the outer film (2) and the first and second inner films (31, 32) are drawn with thick solid lines.

  The rectangular outer film (2) is a single piece, and there are parts that can be cut, such as cut drape for cutting, intermittent cutting, and cutting for easy cutting at the film edge using a directional film. do not do.

The first inner film (31) covers the outer film (2) except for one end side of the outer film (2). The second inner film (32) covers the other end of the outer film (2) that is left uncovered by the first inner film (31) (the end of the first inner film (31) that is not covered). .
The second inner film (32) integrally forms extension portions (33) and (33) protruding from both side edges along the longitudinal direction of the outer film (2), and the extension portions (33) and (33) are packaged. It is a size which is too much to cover the end face of the stick-shaped rice cake (6) to be processed. The second inner film (32) has both sides and ends joined to the outer film (2) by welding (13), (13) and (14).

The first inner film (31) is approximately 1 cm wide and overlaps the second inner film (32).
The above numerical values are examples and do not limit the present invention.

The sheet-like food (4) is a sheet-like seaweed in the embodiment, and the length thereof is a length that allows the circumferential surface of the stick-shaped rice lump (6) to be wound more than one round. The width | variety length of a sheet-like foodstuff (4) respond | corresponds to the length of a stick-shaped rice lump (6).
The sheet-like food (4) is accommodated between the outer film (2) and the first inner film (31) to form a packaging sheet body (1) and is close to the second inner film (32). The inner end of the food (4) protrudes about 1 cm from the inner end (34) of the first inner film (31).

As shown in FIG. 1, at the outer periphery of the outer film (2), the outer film (2) and the first inner film (31) are connected by welding (11), (11), and (12). ) Between the two films (2) and (31).
In the welding of the outer film (2) and the first inner film (31), the strength of the welding (11) (11) on both sides along the longitudinal direction of the outer film (2) has the following conditions.
As shown in FIG. 8, when unpacking the packaged rice lump (7), spreading the packaging sheet body (1) and peeling the first inner film (31), the welding (11) on both sides is easy. Must be off. It is because peeling of a 1st inner film will become difficult when welding (11) is too strong. The weld (12) at the end of the outer film (2) may be as weak as the welds (11) on both sides, but need not be weakened.

As shown in FIG. 1, the ends (11a) and (11a) of the welds (11) and (11) between the outer film (2) and both side edges of the first inner film (31) reach the second inner film (32). There is no appropriate distance (1-2 cm in the embodiment) from the inner side edge (32a) of the second inner film (32).
The ends (13a) and (13a) of the welds (13) and (13) on both sides of the outer film (2) and the second inner film (32) do not reach the protruding edge of the sheet-like food (4). The distance from the projecting edge is a suitable distance (0.5 to 1 cm in the embodiment).
As another example of the first inner film (31), there is a configuration shown in FIG. In FIG. 3a, the first inner film (31) extends the auxiliary piece (36) to the leading edge of the second inner film (32), and the outer film (2), the extension piece (36), and the second inner film. The film (32) is stacked and welded (14), and an opening line (37) such as a sewing line is applied at a position corresponding to the tip of the first inner film (31) in FIG. Since this embodiment is bound as compared with the first inner film (31) of FIG. 3, there is an advantage that moisture does not easily enter from the mass of rice (6). In order to open the first film (31), the perforation of the open line (37) can be cut and opened in the same manner as in FIG.

  However, in order to wrap the stick-shaped rice cake (6) with the packaging sheet (1), as shown in FIG. 1, the first and second inner films (31) and (32) are placed on the upper side, and the packaging sheet body (1 ). On the second inner film (32), the bar-shaped rice cake (6) is placed so as to be orthogonal to the longitudinal direction of the outer film (2). Next, the extension parts (33) at both ends of the second inner film (32) are put on both end faces of the rod-shaped rice cake (6), and then the packaging sheet (1) is wound around the peripheral surface of the rod-shaped rice cake (6). . At the winding end of the packaging sheet body (1), an adhesive layer is applied to the back surface and a label (5) having a cut tape (51) is adhered and fastened, and the packaged rice cake (7) shown in FIG. Complete.

To unwrap the packaged rice cake (7) and wind the sheet-like food (4) around the rod-shaped food cake (6), the following procedure is followed.
As shown in FIG. 6, the cut tape (51) is pulled up to divide the label (5), and the packaging sheet (1) is developed. As shown in FIG. 7, the second inner film (32 ) Is extended to release the rod-shaped rice cake (6), and the rice cake (6) is supported on the second inner film (32).
Next, as shown in FIG. 8, the inner end (34) of the first inner film (31) is raised so that the overlap between the first inner film (31) and the second inner film (32) opens, and the arrow (35 ) To peel off the first inner film (31). Since the welded parts (11) and (11) on both sides are weak joints, they can be easily detached by peeling them off by hand. As shown in FIG. 9, the first inner film (31) is only welded at the end (12). It leaves and peels from an outer film (2), and the sheet-like foodstuff (4) whole is exposed on an outer film (2). Therefore, the stick-shaped rice cake (6) on the second inner film (32) is moved slightly to the exposed end (4a) of the exposed sheet-like food (4) to move the stick-shaped rice cake (6 ) Is attached to the exposed portion of the sheet-like food (4). As shown in FIG. 10, when the rice lump continues to roll, the sheet-like food (4) can be wrapped around the rice lump, and when the winding is finished, the rice lump is covered with the sheet-like food (4) as shown in FIG. So you can have it in your hand and eat it as it is.

  FIG. 11 is an example in which the packaging sheet body (1) is applied to a bar-shaped rice lump having a rectangular cross section. The packaged rice cake (7) can be made in the same manner as the packaging of the rice cake having a circular cross section.

  The above description is provided to illustrate the present invention and should not be construed as limiting the invention described in the claims or reducing the scope thereof.
