Further, such an outer sheet includes a pair of cut tapes extending in the longitudinal direction, and is configured such that one end of the pair of cut tapes is located between the pair of cut portions.

On the other hand, the inner sheet is configured to have substantially the same shape as the outer sheet. The inner sheet is composed of two sheet pieces. When the outer sheet and the inner sheet are overlapped with each other, the two sheet pieces are formed on the inner end portion of one sheet piece and the other sheet piece at a position corresponding to the area between the pair of cut tapes of the outer sheet. It is configured so that it overlaps with the inner end. As a result, the inner sheet is configured so that it can be easily divided in the width direction.

When wrapping rice balls using the above-mentioned packaging material, the packaging material is folded back in two in the longitudinal direction so that the rice balls are located between them, and one of the pair of facing portions (picking) facing each other via the rice balls. Both ends in the width direction (hereinafter, also referred to as folded ends) that do not overlap with the rice ball at the opposite portion on which the portion is formed) are folded back toward the other facing portion and overlapped. As a result, both ends of the folded-back overlap, and both ends of the folded-back overlap with the other facing portion. Then, at the position where both ends of the folded-back portion and the opposite portion of the other end overlap, the both ends of the folded-back portion and the opposite portion of the other end are heat-sealed and connected, or the label covers the overlapping area of both ends of the folded-back portion and the opposite portion of the other. By sticking a sticker (printed product information, etc.), the rice ball is maintained in a packaged state (see Patent Documents 1 and 2).

One end is formed so as to reach the edge of the extending portion 1c, and the interval is widened from the main body portion 1a side toward the extending portion 1c side. Therefore, as described above, even if the pair of bilateral extending regions 1i and 1i are connected to each other and the folded state is maintained, the knob portion 1g formed between the pair of cut portions 1f and 1f is the main body. As the distance from the portion 1a increases, it becomes easier to spread in a planar shape. Thereby, 1 g of the picking portion can be easily picked.

Further, the outer sheet 3 includes an outer sheet main body portion 3a constituting the main body portion 1a, an outer sheet extending portion 3c forming the extending portion 1c, and a pair of cut portions 1f and 1f. The sheet 2 includes an inner sheet main body portion 2a constituting the main body portion 1a and an inner sheet extending portion 2c forming the extending portion 1c. Further, the portion constituting the pair of bilateral extension regions 1i and 1i in the outer sheet extension portion 3c and the portion constituting the pair of both side extension regions 1i and 1i in the inner sheet extension portion 2c are connected. , The region between the pair of cut portions 1f, 1f in the outer sheet 3 is configured so as not to be connected to the inner sheet 2. Therefore, when the cooked rice processed food A is packaged so that the outer sheet 3 is on the outside, the pair of both side extending regions 1i and 1i are connected to each other so that the pair of cut portions 1f and 1f are in the vicinity (picking). A gap is less likely to occur between the outer sheet 3 and the inner sheet 2 (in the vicinity of the portion 1 g). Therefore, it is possible to suppress the invasion of foreign matter between the outer sheet 3 and the inner sheet 2 and the deterioration of the quality of the sheet-shaped food B.

Further, since the sheet-shaped food B is arranged between the outer sheet main body 3a and the inner sheet main body 2a, the sheet-shaped food B does not overlap with the extending portion 1c. Therefore, it is possible to prevent the work of connecting the pair of bilateral extending regions 1i and 1i from adversely affecting the quality of the sheet-shaped food B.

Further, the extension portion 1c includes a pair of extension pieces 1d and 1d formed at intervals in the second direction with the virtual line L as a boundary, and the pair of extension pieces 1d and 1d are virtual. It is formed in the vicinity of the line L. As a result, in the folded state, the pair of bilateral extending regions 1i and 1i are connected to each other in the vicinity of the folded position, so that sealing in the vicinity of the folded position can be performed satisfactorily.

Further, a pair of bilateral extending regions 1i and 1i can be connected at a position overlapping the portion of the separating portion 1n that constitutes the other facing portion 1k. As a result, the separated portion 1n is separated from the other region in the state where the cooked rice processed food A is packaged (that is, the main body portion 1a is cut), so that a pair of bilateral extending regions in a connected state The 1i and 1i and the separated separation unit 1n come into contact with each other. As a result, the pair of bilateral extending regions 1i and 1i are disconnected along with the cutting of the main body portion 1a (separation of the separating portion 1n), so that the state in which the cooked rice processed food A is packaged can be easily released. ..

The packaging material for cooked rice processed foods according to the present invention is not limited to the above embodiment, and various modifications can be made without departing from the gist of the present invention. Further, the configurations and methods of the plurality of embodiments described above may be arbitrarily adopted and combined (the configurations and methods of one embodiment may be applied to the configurations and methods of other embodiments). Of course, the configuration and method according to the following various modification examples may be arbitrarily selected and adopted for the configuration and method according to the above-described embodiment.

For example, in the above embodiment, the extension portion 1c is composed of a pair of extension pieces 1d and 1d, but the present invention is not limited to this, and for example, as shown in FIG. 5A, a virtual extension portion 1c is formed. It may be formed so as to be continuous in the second direction across the line L.

Further, in the above embodiment, each extension piece 1d includes an inclined edge formed so as to be separated from the virtual line L in the extension direction, but the present invention is not limited to this, and for example, As shown in FIG. 5B, it may be configured to include an inclined edge that approaches the virtual line L in the extending direction and an edge that extends along the virtual line L. In such a case, each end portion of the pair of cut portions 1f and 1f is inclined so as to approach the virtual line L as the distance from the first end portion 1b of the main body portion 1a in each extension piece 1d increases in the extension direction. It may be formed to reach the edge.

Further, in the above embodiment, the inner sheet 2 is configured to include the inner sheet extending portion 2c (specifically, a pair of inner sheet extending pieces 2d, 2d), but the present invention is limited to this. Instead, for example, as shown in FIG. 6, the inner sheet 2 may be configured not to include a portion constituting the extension portion 1c. In such a case, a pair of bilateral extending regions 1i and 1i are formed by the regions on both ends in the second direction from the pair of outer sheet notching portions 3f and 3f in the outer sheet extending portion 3c.

According to such a configuration, the outer sheet 3 includes an outer sheet main body portion 3a constituting the main body portion 1a, an outer sheet extending portion 3c forming the extending portion 1c, and a pair of cut portions 1f and 1f. The inner seat 2 is configured to include an inner seat main body 2a constituting the main body 1a and not to include a portion constituting the extending portion 1c. Further, a pair of bilateral extending regions 1i and 1i are formed by the regions on both ends in the second direction from the pair of notch portions 1f and 1f in the outer sheet extending portion 3c. Therefore, when the cooked rice processed food A is packaged so that the outer sheet 3 is on the outside, the pair of both side extending regions 1i and 1i are connected to each other so that the pair of cut portions 1f and 1f are in the vicinity (picking). A gap is less likely to occur between the outer sheet 3 and the inner sheet 2 (in the vicinity of the portion 1 g). Therefore, it is possible to suppress the invasion of foreign matter between the outer sheet 3 and the inner sheet 2 and the deterioration of the quality of the sheet-shaped food B.

Further, since the sheet-shaped food B is arranged between the outer sheet main body 3a and the inner sheet main body 2a, the sheet-shaped food B does not overlap with the extending portion 1c. Therefore, it is possible to prevent the work of connecting the pair of bilateral extending regions 1i and 1i from adversely affecting the quality of the sheet-shaped food B.

Further, in the above embodiment, the extension portion 1c is composed of the inner sheet extension portion 2c and the outer sheet extension portion 3c, or the extension portion 1c is composed of only the outer sheet extension portion 3c. However, the present invention is not limited to this, and for example, the extension portion 1c may be configured only by the inner sheet extension portion 2c.

Further, the portion of one facing portion 1j that is folded back toward the other facing portion 1k and the other facing portion 1k may overlap and be connected by a heat seal or the like.

Further, in the above embodiment, the pair of bilateral extending regions 1i and 1i are connected in a state of being in the palm of one's hand (a state in which one of the troublesome areas faces each other), but the present invention is not limited to this, and for example, one of them is used. Surface and the other surface may be connected in a state of facing each other.

Further, in the above embodiment, the sheet-shaped food is accommodated between the inner sheet 2 and the outer sheet 3 to form the packaging material 1, but the present invention is not limited to this, and for example, only the outer sheet 3 is used. The packaging material may be composed of.

Further, in the above embodiment, the main body portion 1a (outer sheet 3) is configured to include the separating portion 1n, but the present invention is not limited to this, and for example, the main body portion 1a (outer sheet 3) is one. It may be configured to be cut only on one virtual line extending in the direction (ie, cut so that there is no part to be separated).

Further, in the above embodiment, the packaging material 1 for cooked rice or grazing food is configured to include the extension portion 1c, but the present invention is not limited to this, and for example, the packaging material 1 for cooked rice or grazing food is extended. It may be configured not to include the portion 1c (that is, only the main body portion 1a). In such a case, the pair of cut portions 1f and 1f are formed so that one end portion in the first direction reaches the end edge of the main body portion 1a, and are spaced apart from the other end portion in the first direction toward one end portion. Is formed to expand.

Further, in the above embodiment, the strip-shaped separating portion 1n is formed in a straight line in which both side edges extending in the longitudinal direction are parallel (so that the distance between the side edges does not substantially change), but the present invention is limited to this. However, for example, the distance between the side edges of the strip-shaped separation portion 1n may be continuously widened from both ends in the longitudinal direction toward the center portion. Alternatively, each of both side edges of the separating portion 1n may be formed in a wavy shape.
